In this paper, we propose a robust tracking control scheme for a class of uncertain strict‐feedback nonlinear systems. In these systems, the control signal is quantized by a class of sector‐bounded quantizers including the well‐known hysteresis quantizer and logarithmic quantizer. Compared with the existing results in input‐quantized control, the proposed scheme can control systems with non‐global Lipschitz nonlinearities and unmatched uncertainties caused by model uncertainties and external disturbances. It is shown that the designed robust controller ensures global boundedness of all the signals in the closed‐loop system and enables the tracking error to converge toward a residual, which can be made arbitrarily small.

AbstractThis paper comprises five main sections. The introduction traces the gradually increasing commitment to industrial subjects in the first 70 years of the Royal Commission's existence i.e. up to 1978, a year which was to prove something of a watershed. The second section reviews developments since that date; the third section outlines the 1986 situation while the fourth section, as a separate essay, deals with the computerisation of the Royal Commission's archives and discusses the problems and potential of such an exercise. The final part outlines possible responses to the problem of recording industrial sites in the face of an accelerating rate of destruction.


THE BVA's position of support for the forthcoming pilot culls of badgers in the west of England is, we believe, not representative of majority scientific or veterinary opinion.

As members of the veterinary profession, we are deeply concerned that the shooting of free-roaming badgers at night with shotguns and rifles is very likely to have detrimental welfare impacts on a large number of individual badgers, which may be shot, maimed and severely injured, but not killed outright. The natural behaviour of …


The interaction of shock-induced ejecta with gas beyond the free surface is a critical unsolved issue and being investigated broadly. Using models containing micrometer-sized gas environments, we perform molecular dynamics simulations to investigate the coupling interactions of surrounding gases with ejecta from shock-loaded tin surface. Ejected microjets experience progressively aggravated deceleration with increasing gas density, and particle flows ahead of jet tips are suppressed. Despite the drag effect, the primary fragmentation process is yet intrinsically dominated by a velocity gradient. The continuous interaction between ejecta and gas leads to the progressive formation of transmitted shock waves in background gases, which is jointly determined by ejecta velocity and thermophysical properties of gas. Meanwhile, a mixing layer between ejecta and gas is directly observed, leading to discrepant mass distributions of ejecta along shock direction. With increasing gas density, the volume density tends ...

The interaction of 3,6-dihydrazino-1,2,4,5-tetrazine(DHT) with main components of solid propellant was studied by DSC,and the interaction of DHT with the slurry of CMDB propellant was investigated by curing experiment.The results show that there are no obvious interaction between DHT with cyclotetramethylenete-tranitramine(HMX),hexanitrohexaazaisowurtzitane(CL-20),nitrocellulose(NC),aluminum powder(Al powder),carbon black(CB),polyethylene glycol(PEG),2-nitrodianiline(2-NDPA),1,3-dimethyl-1,3-diphenyl urea(C2) and diisocyanate(N100).The influence between them is a main physical process.There are the strong interaction between DHT with nitroglycerine(NG),cyclotrimethylene-trinitramine(RDX),3,4-dinitrofurazanofuroxan(DNTF),N-guanylurea-dinitramide(FOX-12),N-nitrodihydroxyethylaminedinitrate(DINA) and resorcinol(Res).DHT is found to partly dissolve in these components or to form an eutectic system with these components that can decrease the decomposition temperature of DHT.The DHT/CMDB propellant mixture system can fire when the slurry of the propellant is cured at 70℃ for about 40 minutes,indicating that DHT can not be applied to the double-base propellant or other energetic mixture system that NG is as the main component.


The work's objective was to determine the influence of food ingredients, which can have direct effect of the oxidative stress neutralization (dihydroquercetin and shelf fungus extract), on the quality and preservation of bakery products. The objects of the research were the samples of wheat-and-rye dough and bread with dihydroquercetin and shelf fungus, as well as a reference sample without any additives. The organoleptic assessment of the samples under study allows to conclude on the pronounced influence which the introduced additives have on the appearance, crust colour and crumb structure of bread. However, the introduction of additives does not have any obvious effect on changing of flavour and aroma of the baked products. The assessment of the antioxidative activity of the studied samples of wheat-and-rye dough and crumb of bread made of it revealed that the samples of dough with additives showed 2.4–2.6 times higher antioxidative activity as compared to the reference sample. Once baked, the still enriched bakery products had higher antioxidative activity than the reference sample. Meanwhile, bread with shelf fungus showed the highest antioxidative activity (2.4 times higher as compared to the reference sample). A dependence was determined between the rheological characteristics of the studied and reference samples of wheat-and-rye dough and bread. The density of the dough produced using innovative technologies is somewhat higher as compared to the dough manufactured by the traditional technology. Adding shelf fungus extract reduces the general deformation of the bread crumb by 33%, what increases the degree of crumbling. And dihydroquercetin on the contrary slightly increases the general deformation by 9% and therefore makes the bread crumb more elastic.


Key Points Question Are temporal fluctuations in positive affect associated with mortality risk in older adults? Findings In this survey study of 3834 adults aged 50 years or older, greater instability of momentary positive affect was associated with increased risk of mortality. Meaning This finding suggests that instability of positive affective states in everyday life is relevant to health in old age.


Histamine poisoning is caused by the consumption of fish and other foods that harbor bacteria possessing histidine decarboxylase activity. With the aim of preventing histamine formation, highly specific mass spectral fingerprints were obtained from the 16 major biogenic amine‐producing enteric and marine bacteria by means of MALDI‐TOF MS analysis. All bacterial strains analyzed exhibited specific spectral fingerprints that enabled its unambiguous differentiation. This technique also identified peaks common to certain bacterial groups. Thus, two protein peaks at m/z 4182±1 and 8363±6 were found to be present in all Enterobacteriaceae species analyzed except for Morganella morganii. Peaks at m/z 3635±1 and 7267±2 were specific to both M. morganii and Proteus spp. Biogenic amine‐forming Proteus spp. exhibited three genus‐specific peaks at m/z 3980, 7960±1 and 9584±2. The genus Photobacterium also showed three genus‐specific peaks at m/z 2980±1, 4275±1 and 6578±1. The two histamine‐producing Gram‐positive bacteria Lactobacillus sp. 30A and Staphylococcus xylosus exhibited a few protein peaks in the 2000–7000 m/z range and could be easily distinguished from biogenic amine‐forming Gram‐negative bacteria. Clustering based on MALDI‐TOF MS also exhibited a good correlation with phylogenetic analysis based on the 16S rRNA gene sequence, validating the ability of the MALDI‐TOF technique to establish relationships between microbial strains and species. The approach described in this study leads the way toward the rapid and specific identification of major biogenic amine‐forming bacteria based on molecular protein markers with a goal to the timely prevention of histamine food poisoning.


In an article in the BBC News Magazine some years ago, Lyman Frank Baum's (1856–1919) novel The Wonderful Wizard of Oz was called "one of the world's best-loved fairytales" (Jahangir 2009). The story of little Dorothy Gale being swept away from her home on a farm in Kansas by a cyclone and carried to a magical parallel world called the "Land of Oz," where she encounters numerous unknown creatures and dangers and has to survive various adventures before finally finding her way back home, is indeed one of the most popular literary fairy tales of the Modern Period. Ever since its first publication in 1900, 1 Baum's narrative has been an unparalleled commercial success, and this success continues to this day, especially in the U.S. Aside from countless reprints and translations, Baum's story was further popularised, and thus gradually became part of America's common cultural heritage, through a total of thirteen sequels and, in particular, by its adaptation to an early Technicolor film by MGM in 1939. 2 In modern scholarship, after a first period of almost virtual negligence, allegorical readings became increasingly popular and have remained so to this day. In this paper, I will suggest an alternative reading of Baum's novel, using Homer's Odyssey as its backdrop and hypotext. It will be shown that the Homeric Odyssey provides a key intertextual model of The Wonderful Wizard of Oz, the most important narrative devices of which are the Odyssean motifs of homecoming, transgression, and transformation. Furthermore, it will also be demonstrated that the character of Dorothy is, contrary to common assumption, not subject to development or maturation in the course of the narrative, but rather she is presented as a quasi-adult person from the very beginning of the novel, similarly to how the epic hero Odysseus, who is already a fully grown and mature man when he embarks upon his nostos, is depicted in the Odyssey.


The campaign conducted by the Congo Free State from 1892-1895 against the 'Arabs', who dominated the western part of its territory, had important consequences. Now, at the centenary of the beginning of this campaign, it is time to shed light on two relevant historical sources of this campaign.The first is a beautiful cup with Arab inscriptions and decorations, no doubt taken as booty after the Sefu defeat at the battle of Chige, the first of the campaign (23 November 1892).The second source, this time written, is a letter from Captain Scheerlinck, sent from Lusambo, on November 3rd 1893, to a certain 'Henri'. As the author has not identified the addressee, this article will attempt to do so. The article will also try to decipher an 'illegible' passage in the letter and to clarify the reference to an American 'Factorien' in the letter.


At the T(d,n)He4 reaction each 14 MeV neutron is accompanied by a 3.5 MeV alphaparticle emitted in the opposite direction. A positionand time-sensitive alpha-detector measures time and coordinates of the associated alpha particle which allows determining time and direction (tags) of neutron escape. The tagged neutron technology is based on a time and spatial selection of events that occur when a tagged neutron moves through the object. The VNIIA ING-27 neutron generators produce intensive beams of tagged neutrons in a wide cone angle with the high spatial and time resolution of tagged neutrons provided by the pixelated fast alpha-detector. Requirements to a DAQ system for various tagged neutron devices are reported. The architecture and parameters of the DAQ system based on preliminary online selection of signals by analog front-end electronics and transmission of only useful events for subsequent computer processing are considered. The examples of tagged neutron devices for various applications are discussed.


Objective To investigate the clinical effects of calcium dobesilate on early diabetic nephropathy.Methods 42 patients with early diabetic nephropathy were randomly divided into the treatment and control groups.All the patients were given treatment to control blood glucose and 21 patients in the treatment group were treated with calcium dobesilate(500 mg,three times per day) for 12 weeks.Urinary albumin excretion,plasma endothelin,serum nitric oxide,serum glucose,glycosylated heamoglobin A1c,hepatic and renal function were determined before and after the treatment.Results After 12 weeks of treatment,in the treatment group the levels of UAE were significantly decreased(P0.01),the levels of ET were decreased,the levels of NO were increased,and the levels of serum glucose and HbA1c had no changes.However,the levels of UAE,ET,NO,serum glucose and HbA1c had no changes in the control group.Conclusion Calcium dobesilate can decrease the levels of UAE in patients with early diabetic nephropathy and postpone the development of diabetic nephropathy,which may be due to its correction of abnormal renal hemodynamics through decreasing ET and increasing NO.


[Extract] This commentary is a response to those of Hall (2016) and Winebrenner (2016), which in turn were responses to our article on modality preferences and learning styles (Lodge, Hansen, & Cottrell, 2016). There are several key points we wish to address. Most importantly, and aligned with the aims and focaus of Learning: Research and Practice, we would like to take the opportunity to discuss why learning styles provide a key example of what happens when the link between resarch and practice is coroded.


Dear Sir It is well established that certain individuals with episodic migraine will develop chronic daily headaches, which suggests that migraine may be a clinically progressive disease in individuals at risk (1). Additionally, a recent study proposes that migraine may also be an anatomically progressive disease. Kruit et al., in a large cross-sectional population study, found that migraine sufferers were at significantly increased risk of clinically silent infarctlike lesions in the posterior circulation territory of the brain, notably in the cerebellum (2). The adjusted odds ratio (OR) was 13.7 [95% confidence interval (CI) 1.7, 112] for patients with migraine with aura compared with controls. The highest risk was in patients with migraine with aura with one attack or more per month (OR 15.8; 95% CI 1.8, 140). Furthermore, based on the radiological aspects of the lesions, they suggest that a combination of possible migraine attack-related hypoperfusion and embolism is the likeliest mechanism for PC infarction in migraine, and not atherosclerosis or small-vessel disease (2, 3). Recent evidence also suggests that migraine (possibly more so migraine with aura), is comorbid with patent foramen ovale (PFO), which may explain some of the silent brain lesions (4). Finally, migraine with aura has been consistently suggested as a risk factor for stroke in young women (5, 6). Based on these findings, there has been much interest in theoretical prospects for avoiding migraine progression, and proposals that the role of preventive treatment in the management of migraine must be reassessed, based on the fact that timely use of daily preventive treatment might modify the long-term outcome of migraine sufferers (7). According to some authors, preventive therapy should be used when patients experience as little as two migraines per month; have severe, recurring migraine; or are overusing or have failed acute medications. The argument is that reductions in attack frequency and severity by migraine prevention decrease the likelihood of drug overuse and may reduce the risk of facilitating pain transmission, neuroplasticity, and subsequent transformation to a more chronic, refractory and disabling form of migraine. Although we absolutely agree that preventive medication is often underutilized and that the use of prevention may reduce attack frequency and severity and, therefore, pain and disability, we ask ourselves if we are not missing the point. Regarding preventive therapies, it is important to emphasize that:


Boron nitride (BN) powder was modified by silane coupling agent, and a series of cyanate ester resin composites containing the modified BN were prepared. The effect of volume fraction of BN on the thermal conductivity, electrical insulation properties of these composites was investigated. Results show that addition of a little of BN powder can improve thermal conductivity of the composites effectively, while the composites still retain the relatively good electrical insulation and low dielectric constant. When the volume fraction of BN was 23.6%, the thermal conductivity of composite increased to 1.33 W/(m·K), which is 4.6 times that of pure resin.


Objective The study takes the aromatization of adipose tissue as the breakthrough point to probe the molecular mechanism of male sex hormone disorder produced by obesity and the effect and mechanism of different exercise loads in alleviating the male sex hormone disorder.The research aims to provide the experimental basis for investigating the mechanism of obesity and exercise produced or improved male sex hormone disorder,and to provide the theoretical basis for exploring the effective exercise load.
Methods A total of forty 3-week-old C57BL/6 male mice were randomly divided into normal control group feeding with normal diet and obesity model group feeding with high fat diet,ten mice for normal control group and thirty mice for obesity model group.We got rid of one mouse which weight did not reach the standard after 10-week of high fat diet.Obesity model group were randomly divided into obesity control group,moderate-load exercise group and high-load exercise group,nine mice for obesity control group and ten mice for moderate-load exercise group and high-load exercise group feeding with high fat diet.Moderate-load exercise group was assigned to 1time/d,2h/time,6d/w non-weight-bearing free swimming.High-load exercise group were assigned to 2times/d, 2h/time,6d/w non-weight-bearing free swimming. After 8-week swimming training,there was one mouse died in each of the exercise group.
After training,the sperm counts were observed by inverted microscope.The serum luteinizing hormone(LH),Follicle-stimulating hormone(FSH),Testostrone(T)and Estradiol (E2) were tested with Elisa method.The genetic transcription and protein expression of the interleukin-6(IL-6),Interleukin-6 Receptor(IL-6R) and aromatase in adipose tissue were detected by Real-time PCR and Western blot.
Results 1.Compared with normal control group,weight, fat weight and body fat rate of mice in the obesity control group were significantly increased(P<0.01,P<0.01,P<0.05);Serum Luteinizing hormone(LH),Follicle-stimulating hormone(FSH),Testostrone(T)in the obesity control group were significantly decraesed(P<0.05) and serum estradiol(E2)was significantly increased(P<0.01);Sperm counts and sperm activity of mice in the obesity control group were significantly decraesed(P<0.01);The genetic transcription levels of interleukin-6(IL-6),Interleukin-6 Receptor(IL-6R) and aromatase in adipose tissue in the obesity control group were significantly increased(P<0.01)and the protein expression were significantly increased(P<0.05,P<0.01,P<0.05).
2.Compared with obesity control group,weight,fat weight and body fat rate of mice in the moderate-load exercise group were significantly decraesed(P<0.01,P<0.05,P<0.05);Serum Luteinizing hormone(LH),Follicle-stimulating hormone(FSH),Testostrone(T)in the moderate-load exercise group were significantly increased(P<0.01,P<0.01,P<0.05) and serum Estradiol(E2)was significantly decraesed(P<0.01);Sperm counts and sperm activity of mice in the moderate-load exercise group were significantly increased(P<0.01,P<0.05);The genetic transcription and the protein expression of interleukin-6(IL-6),Interleukin-6 Receptor(IL-6R) and aromatase in adipose tissue in the moderate-load exercise group were significantly decraesed(P<0.01).Compared with obesity control group,weight,fat weight and body fat rate of mice in the high-load exercise group were significantly decraesed(P<0.01,P<0.05,P<0.05);Serum luteinizing hormone(LH),Follicle-stimulating hormone(FSH),Testostrone(T) and Estradiol(E2) in the high-load exercise group have no significant differences(P>0.05);Sperm counts and sperm activity of mice in the high-load exercise group were also have no significant differences(P>0.05);The genetic transcription levels and the protein expression of interleukin-6(IL-6),Interleukin-6 Receptor(IL-6R) and aromatase in adipose tissue in the high-load exercise group have no significant differences(P>0.05).
3.Compared with moderate-load exercise group,weight,fat weight and body fat rate of mice in the high-load exercise group were significantly decraesed(P<0.05);Serum luteinizing hormone(LH),Follicle-stimulating hormone(FSH) ,Testostrone(T) in the high-load exercise group were significantly decraesed(P<0.01) and Serum Estradiol(E2) have no significant differences(P>0.05);Sperm counts and sperm activity of mice in the high-load exercise group were significantly decraesed(P<0.01);The genetic transcription levels of interleukin-6(IL-6),Interleukin-6 Receptor(IL-6R) and aromatase in adipose tissue in the high-load exercise group were significantly increased(P<0.05,P<0.01,P<0.01);The protein expression of Interleukin-6(IL-6),aromatase in adipose tissue in the high-load exercise group were significantly increased(P<0.01),but Interleukin-6 Receptor have no significant differences(P>0.05).
4.IL-6 correlated positively with aromatase(r=0.776,P<0.01) and Estradiol(E2)(r=0.414, P<0.05) and correlated negatively with Testostrone(T)(r=-0.572,P<0.01);IL-6R correlated positively with aromatase(r=0.435,P<0.01) and Estradiol(E2)(r=0.486, P<0.01) and  correlated negatively with Testostrone(T)(r=-0.321,P>0.05);Aromatase correlated negatively with Testostrone(T)(r=-0.562,P<0.01) and positively with Estradiol(E2) (r=0.435,P<0.01).
Conclusions 1.Eighteen weeks of high fat diets for male mice led to serious obesity and facilitated the inflammation in adipose tissue.The up-regulation of gene and protein expression of adipose tissue IL-6 stimulated aromatization and prompted testosterone converted into estrogen,leading to sex hormone disorder.
2.Long-term moderate-load exercise reduced the body fat effectively and inhibited the gene and protein expression of adipose tissue IL-6.Meanwhile,it inhibited the aromatization and improved sex hormone disorder associated with obesity.
3.Long-term high-load exercise reduced the body fat significantly,but had no effect on aromatization which was mediated by adipose tissue IL-6,nor relieved male sex hormone disorder associated with obesity.


The Paleogene turbiditic sedimentation in the eastern Southern Alps represents the sedimentary response to tectonic activity related to the Mesoalpine phase, which involved the surrounding chains from Paleocene onwards. Field and petrographic analyses have allowed to classify these turbiditic successions as multisource deposits, as demonstrated by the common presence of allochemical, mainly bioclastic detritus, associated with different types of terrigenous arenites. Field data suggest more proximal sources for allochemical supply and distal sources for terrigenous material, characterized by the presence of chert, carbonate rocks and metamorphic rock fragments. All the investigated successions display transparent heavy mineral associations, marked by the common presence of Crspinel, alcaline amphibole, staurolite, epidote, and zoisite, pointing to similar metamorphic sources. The location of the source of metamorphic rock fragments is uncertain, but inputs from the internal Dinaric belt are possible. The source of the allochemical detritus was located in the nearby re-activated Friuli Platform.


At least two species of Tubifex are abundant in Scotland, one of which is, perhaps, more prevalent in streams, the other in lakes. The former is common at the margin of the river Tay, when the water is low, in sandy tubes of little tenacity, and often in tunnels formed amongst the wet sand under stones, just as many of the marine annelids occur. Its length varies from three-fourths of an inch to an inch and a-half when stretched, and the segments range from fifty to seventy, the average number probably being sixty. The body is of various shades of dull fawn or pale madder-brown, somewhat interrupted by the pale bands at the junctions of the segments, and streaked by the reddish dorsal vessel; or, in summer, marked anteriorly by the whitish mass of the reproductive organs. It is easily recognised amongst its fellows by its faintly purplish or lilac hue, as well as by its peculiar mode of progression; and not a few are observed with reproducing heads and tails. This form, perhaps, has most claim to be called Tubifex rivulorum.


Taking 135 MW sets as a practical example,the profitability of flue duct positioned low pressure feed-water heaters is quantitatively analyzed,in consideration of the boilers thermal efficiency,the turbine's output,the increase of the feed-water pump's and induction fan's power consumption,as well as the corresponding investment required.The conclusion points out,that it is not recommendable to use such a positioned heater as a substitute for the turbine regeneration system's second stage low pressure heater for effectuating the latter's performance.


The article examines motivators of energy conservation behavior and accesses to its implementation via educational system. There were elicited the main challenges that face Russians on such a way of transformation to energy effective conservation practice, among which the most outstanding are: established lifestyles, a lack of rigid governmental standards regards energy consuming production, the absence of clearance in understanding of actions required to be taken by individuals, rent-seeking behavior of officials, businessmen, company's head power engineers and so on. Thus, Russians miss inner conviction in respect of effectiveness of their energy conservation actions taken in the background of the common inactivity as well as state mechanism which misses a practical realization of energy conservation policy. Authors concluded that implementation of elements of energy conservation through education will contribute to form a motivation and will facilitate some changes in the behavior of Russian people behaviors towards energy conservation practices. Authors also give a brief review of some foreign theories and practices of introduction of energy conservation through education.


The invention provides a vibration wave driving device based on barium calcium zirconate titanate material that can be driven with high reliability over a wide operating temperature range includes a piezoelectric element (P), and a temperature compensation capacitor (C) in parallel, such that the relations 20 DEG C <=T[epsilon](Cmax) - T[epsilon](Pmax) <=75 DEG C and 0.50 <= [epsilon] (Cc)/ [epsilon](Cmax) <= 0.80 involving the relative dielectric constants [epsilon] and temperatures at their maximum values T[epsilon] are satisfied.


The purpose of this study was to verify the effects of psychodrama group counselling, and to determine its applicability as a nursing intervention for the promotion of mental health of clients in their developmental stages. Methodological triangulation was used for research design. For quantitative study, quasi experimental study design with nonequivalent control group was used to test the effects of psychodrama group counselling. For each experimental and control group convenient samples of 15 nursing students were selected, and observed from May to Nov. 2000. For experimental group, the treatment was given for 2 hours each week, totaling 20 hours. The questionnaire consisted of 24 items of physical symptoms from CMI. 40 items of Spielberger Anxiety Scale, and 21 items of Beck Depression Scale. Reflective journal was written by the experimental group. The data were analyzed using chi-square and Mann-Whitney U test. For the qualitative study, the contents of the reflective journal were analyzed into categories and classifications. The results of the study were as follows; 1. There was a significant difference on physical health status between the experimental and the control group 2. There was a significant difference between two groups on the mean scores of mental health before and after psychodrama group counselling. 3. The qualitative analysis of reflective journal resulted in 4 categories and 13 classifications, which was reflected by the experience of the psychodrama group counselling. The four categories were self introspection, psychological support, improvement of interpersonal relationship and self development. The thirteen classifications are self-discovery, discovering others, emotional catharsis, positive thinking, formation of consensus, comforting, being free, being comfortable, understanding, maturing personal relationship, acquiring self-confidence, new challenges, and planning for the future. Based on the study findings, the psychodrama group counselling had promoted not only physical but also mental health of nursing students. The characteristics identified by the study suggested the applicability of psychodrama group counselling as an effective measure of nursing intervention for clients.


This paper uses a case study of Ukrainian migrants in Italy and the Czech Republic to demonstrate the similarities in remittance behavior and integration process of same ethnic group in different destination countries. Our findings show that that remittance behavior of Ukrainian migrants in the Czech Republic and Italy is significantly determined by their financial situation, demographic characteristics, level of human capital and the level of integration as well as the specific context characteristics. In addition, we find evidence for the fact that Ukrainian migrants who are more settled in a target country will send less or no remittances to Ukraine and that therefore the Stark's hypothesis of remittances decay holds true for this ethnical group regardless of the country of residence.


Objective To investigate the expression of FOXP3 in cancer cells and FOXP3-positive lymphocyte invasion in the tumor stroma separately,and to evaluate their clinical values in predicting the prognosis of esophagus cancer of the neck.Methods Envision immunohistochemistry and double-immunostaining method were used to detect the expression of Foxp3 and FOXP3-positive lymphocyte invasion in 42 specimens of esophagus cancer of the neck and 30 specimens adjacent to carcinoma.Results The positive rate of FOXP3 protein in parenchyma was 42.9%(18/42)in esophagus cancer of the neck and 6.67%(2/30)in tissues adjacent to carcinoma(χ2=10.324,P0.01).The positive rate of FOXP3-positive lymphocytes in mesenchyma was 38.1%(16/42)in cancer tissues and 13.33%(4/30)in tissues adjacent to carcinoma(χ2=15.376,P0.01).In parenchyma of esophagus cancer of the neck,the expression of FOXP3 protein in the patients with lymph nodes metastasis was positively higher than the patients without(P0.05).And,the expression in stage Ⅲ orⅣ was all positively higher than that in stages Ⅰor Ⅱ(P0.05).In cancer's mesenchyma,the expression rate of FOXP3-positive lymphocytes in the patients with lymph node metastasis was positively higher than those without(P0.05). Conclusion The abnormal expression of FOXP3 protein in cancer's parenchyma and FOXP3-positive lymphocytes infiltration in cancer's mesenchyma may be closely related to metastasis of esophagus cancer of the neck.It could facilitate the immune escape of esophagus cancer of the neck.FOXP3 may be a potential marker to evaluate metastasis of esophagus cancer of the neck.


Static tests and calculating bearing capacity and settlement of largediameter and overlength caisson pile are carried out; and design method is discussed. The Q-S curve of large diameter and overlength caisson pile doesn't have apparent characteristic point, it is slow transformation .The settlement of the pile head is composed of the elastic compression of pile body, the compression of the soil below the pile tip by the load from the pile stem and pile tip. It is shown that the bearing force of largediameter and overlength caisson pile can be determined by displacement control method. Usually, the design bearing capacity is the test load when the pile head's settlement is one percent of its diameter. Elastic compression of pile body has a great influence on pile settlement, the calculated pile settlement by elastic method is bigger than that of test, and the settlement from static tests should be adopted when designing.


Milling is one of the most common and productive edge cutting machining methods in industry. The intermittent cycle of the cutting edge allows the using of high-speed machining principles, which significantly increases the productivity and quality of machining. Cutting temperature is one of the key factors which makes it possible to control the cutting process and tool life to achieve the required product characteristics. First, we analyze the temperature distribution in the cutting zone of the aluminum alloy AMg3. Then, we consider the results of mathematical simulation and experimental studies of thermal processes in the cutting zone when machining critical parts of aerospace structures, depending on the cutting conditions and tool geometry using non-contact measuring instruments. Finally, we give recommendations on temperature control in the cutting zone during the milling process


It deals with a first report of research dedicated to the tourist areas which have reached their maturity, to their ability to absorb the challenges of the market and to their compatibility among different tourist experiences. The components that motivate the tourist flux, the images of the destination area and the relations among subjects, created by the particular atmosphere of the same area, are the theme of the research. In particular, the different images of tourism are studied in each sub-area of the Adriatic coast of Emilia-Romagna, as basic elements of dif-ferent but coexisting behavioural models. The differentiation of the tourist demand would be very interesting because it would be, itself, a powerful cause of attrac-tion and then it would consent new conditions of autonomy for local population in the development of the tourist offering.


We show that a photonic structure composed of silicon dioxide, silicon nitride, and gallium arsenide layers can act as a reflective optical limiter at near-infrared wavelengths. The limiter transmits low intensity light while totally reflecting high intensity laser radiation, thereby protecting the limiter and the sensor from overheating and destruction.


The spatially resolved transmission through porcine liver is measured with a CCD-Camera. A solution of the diffusion equation is derived to investigate whether the optical coefficients can be deduced from this experimental geometry. The inverse problem is solved with a nonlinear regression program using Monte Carlo simulations as solutions of the forward problem. The experiment is tested with latex-spheres, which are described by Mie-Theory.


High specific power electric motor is a key enabling technology for electric/hybrid-electric propulsion for aircraft. High-frequency, air core machine topologies show potential for high specific power when the machines are integrated within jet engines at high speed, e.g. 15,000 rpm. In this paper, we explore how these machines scale to a boundary layer ingestion (BLI) fan application in newly proposed Single-aisle Turboelectric Aircraft with an Aft Boundary Layer Propulsor (STARC-ABL). Detailed analytical models that have been experimentally verified, and an evolutionary genetic algorithm are utilized to choose an optimized design for the BLI propulsor. Analyses show that a 2.6 MW, 11 kW/kg, 98% electric motor is achievable.


The effect of installing a circular cylinder in front of the returning turbine blade in enhancing the self-starting capability of the Savonius wind turbine has been studied experimentally by measuring the static torque of the turbine at the angular positions of the blades. The circular cylinder with a diameter relative to the blade diameter d/D = 0.5 is installed at a distance corresponding to the blade diameter in front of the returning turbine blade which is varied by 1.2 ≤ S/D ≤ 2.6. The experiments were carried out for Reynolds number (Re) = 74,000, 136,000, and 175,000. The results showed that the presence of a circular cylinder installed in front of the returning turbine blade at a distance of 1.4 ≤ S/D ≤ 1.8 was able to achieve the self-starting capability of the Savonius wind turbine as indicated by the positive values of the turbine static torque coefficient at all blade angular positions. The highest performance of the Savonius turbine self-starting capability is obtained at the circular cylinder position S/D = 1.6 for the Reynolds number (Re) = 136,000, and 175,000.


A rotor system can be studied via various approaches, e.g., FEM, the transfer matrix method, etc. The receptance method has been one of the methods used for frequency analysis of rotors. The authors, herein, have shown an application of the receptance matrix for sensitivity analysis. Examples of critical speed sensitivity to support stiffness were illustrated and a computing algorithm was developed. Numerical examples proved the approach to be valuable for rotor engineers in quick evaluation and understanding of the support effects.


The aim of this work is to shed light on the characteristics and relationship between customer loyalty and publications by the companies on social networks; it has been undertaken with the aid of an exhaustive review of previous studies from 1994 up to the present time. The purpose of the research is to generate a model that can tackle the practical characteristics of the publications on social networks to encourage loyalty. With a view to this, a model is developed that is an extension of the traditional "Four Stage Loyalty Model" based on other constructions of the same model, and combined with the characteristics of social networks publications defined in earlier literature. This reflexive approach is particularly important here due to the fact that companies have to be closer to customers' requirements and customers have the option to choose from which type of communication they wish to be the object.


In mobile video applications, where unreliable networks are commonplace, corrupted video packets can have a profound impact on the quality of the user experience. In this paper, we show that, in a wide range of operating conditions, selectively reusing data resulting from decodable errorneous packets leads to better results than frame copy. This selection is guided by a novel concept that combines motion estimation and a measure of blocking artifacts at block edges to predict visual degradation caused by the decoding of erroneous packets. Simulation results show that, by using the proposed solution, the H.264/AVC JM reference software decoder can select the best option between frame copy and the erroneous frame decoding in 82% of test cases. We also obtain an average gain of 1.95 dB for concealed frames (when they differ from those concealed by the JM decoder).


Recent work has pointed out that diagnosis strategies are a necessary tool for the diagnosis of complex systems. Nevertheless, though current diagnosis systems are able to use explicit system models, their representation of diagnosis strategies is only implicit. In this paper we introduce a formal meta language to express strategic knowledge in an explicit way, This language is sufficient to formalize all strategies introduced in previous work, and extends previous diagnosis strategies by the integration of empirical knowledge and by explicit statements about dependencies between actions. We provide a declarative semantics for this language and an architecture for implementation.

Abstract The highbush blueberry (Vaccinium corymbosum L.), which has been cultivated commercially in northwest Arkansas for about ten years, is rapidly gaining popularity in this area. However, problems are becoming apparent with regard to the delicate nutritional balance required by this plant. Symptoms characteristic of iron deficiency were noted in the spring of 1981, and soil and plant analyses were initiated to determine the exact cause of the chlorosis. Soil analysis showed no soil factor to be the direct cause of the chlorosis. Plant analyses, however, showed high phosphorus, high potassium, and low calcium to be associated with the chlorosis. Although plant symptoms were typical of iron deficiency. iron content within the plant was adequate, suggesting iron inactivation from excess phosphorus.


Wireless body area networks (WBANs) are emerging as important networks, applicable in various fields. The network typically extends over the whole human body and the nodes are connected through a wireless communication channel. WBAN consists of sensors, transceivers, battery, processors and accerelerometer. WBANs can be seen as a special purpose sensor networks designed to satisfy Quality of Service (QoS) requirements of physiological signals operating in different environments. This paper surveys the WBANs that are designed for applications in healthcare. We present a comprehensive survey consisting of stand-alone sections focusing on important aspects of WBANs. We examine the following: monitoring and sensing, power efficient protocols, system architectures. We conclude by discussing some open research issues, their potential solutions and future trends.


This qualitative case study examined the beliefs and practice of two teachers in an international school in order to inform debates about the potential of education for critical, transnational, and multiple citizenship. Data from interviews and observations indicated that teachers conceptualized and taught citizenship in ways that reflected the fluid and evolving nature of civic identity, rights, and obligations. However, the teachers noted challenges in linking their students' daily civic experiences and academic programs, and reconciling the school's civic ethos with the wider, nation-centric discursive practices of citizenship in the United States.


The desire to make education accessible to all citizens, has been the focus of many nations in the world. This could be attributed to its roles in individuals and national development. Over the years, attempts had been made to achieve this feat in Nigeria. Unfortunately, after over four decades of attaining independent status, many adult illiterates still abound in Nigeria. Presently, Nigeria is committed to the achievement of Education for All and the Millennium Development Goals. While the country is striving to achieve the goals, this paper examines the challenges such as: limited access to schools, inadequate infrastructural facilities in schools, inadequate fund and teachers, corruption, increase in population, inappropriate planning and implementation, and wastage, which can impede the achievement. Litteratures and relevant data were gathered to describe the existing problem. To tackle the challenges and ensure that the goals are achieved however, allocation of more fund to the education sector, recruitment of qualified teachers and distribution to schools, training and re-training of available teachers, provision of infrastructural facilities for schools by government, wealthy individuals and organizations, are suggested Keywords : Challenge, Achievement, Education, Education for All, Millennium, Development, Goal, Millennium Development Goal


For the first time, we enable the execution of hybrid machine learning methods on real quantum computers with 100 data samples and real-device-based simulations with 5,000 data samples, thereby outperforming the current state of research of Suryotrisongko and Musashi from 2022 who were dealing with 1,000 data samples and quantum simulators (pure software-based emulators) only. Additionally, we beat their reported accuracy of $76.8\%$ by an average accuracy of $91.2\%$, all within a total execution time of 1,687 seconds. We achieve this significant progress through two-step strategy: Firstly, we establish a stable quantum architecture that enables us to execute HQML algorithms on real quantum devices. Secondly, we introduce new hybrid quantum binary classification algorithms based on Hoeffding decision tree algorithms. These algorithms speed up the process via batch-wise execution, reducing the number of shots required on real quantum devices compared to conventional loop-based optimizers. Their incremental nature serves the purpose of online large-scale data streaming for DGA botnet detection, and allows us to apply hybrid quantum machine learning to the field of cybersecurity analytics. We conduct our experiments using the Qiskit library with the Aer quantum simulator, and on three different real quantum devices from Azure Quantum: IonQ, Rigetti, and Quantinuum. This is the first time these tools are combined in this manner.


Abstract Treatment under normal processing temperature has been carried out by kneading for different times and at different roller rotating speeds, and also by successive extrusion cycles. There is an increase in melt viscosity of PES samples after processing. A phenomenon of thickening of melt during processing of PES may occur due to prolonged shear, heat, and oxidation under normal processing temperature (315°–335°C). A systematic study was conducted to investigate the structure changes during processing of PES by a variety of techniques including: Fourier–transform infrared spectroscopy, 13C nuclear magnetic resonance, and x-ray photoelectron spectroscopy. The results indicate that chain scission reactions occur and that long-chain branches are formed due to shear and heating. A branching mechanism provoking increase in molecular weight and thickening of melt during processing of PES is presented based on experimental data.


Combining a high‐capacity material possessing a core@shell structure with a carbon material is a powerful tactic for reinforcing the performance of Li‐ion battery (LIB) anodes. As an efficient and simple approach to obtain tin(II) sulfide (SnS) with ultrafast lithium‐storage capability and cycling stability, we propose the hierarchical core@shell structure of carbon nanofibers@SnS nanotubes (CNF@SnSNTs) covered with S‐doped carbon via a one‐pot carbonization by harnessing the Kirkendall effect of camphene and sulfurization of SnO2 by L‐cysteine. This hierarchical core@shell structure contains mesoporous carbon nanofibers (CNFs) that reduce the Li‐ion diffusion pathway, SnS nanotubes (NTs) that expand the active site, and a S‐doped carbon layer at the faces of the SnS NTs that promotes the electrical conductivity and inhibits volume expansion of SnS. Therefore, a CNF@SnSNT‐C7 electrode achieves superb ultrafast electrochemical performance (528.1 mAh/g under a current density of 2000 mA/g), high specific capacity (2218.2 mAh/g under a current density of 100 mA/g), and an ultrafast cycling stability of 92.9% after 500 cycles under a current density of 2000 mA/g. These performance improvements are resulted from the synergistical effect of mesoporous CNFs, SnS NTs, and S‐doped carbon layer. Therefore, CNF@SnSNT is potential anode material for LIBs having superior Li‐storage capability.


The in situ electrochemical supply of promoters (ionic species), via current and voltage application (typically ±1-2 V) on metal catalyst films, interfaced with solid electrolytes, can cause dramatic and reversible modifications in catalytic activity and product selectivity. The catalytic activity can be enhanced by up to a factor of 100, and the induced change in the catalytic rate is strongly non-faradaic, i.e., up to five orders of magnitude larger than the steady-state rate of electrochemical supply of ionic species from the solid electrolyte onto the catalytic surface. This novel phenomenon has been termed electrochemical promotion or in situ controlled promotion or Non Faradaic Electrochemical Modification of Catalytic Activity (NEMCA) and has been demonstrated for a large variety of catalytic reactions (over 40), catalysts (Pt, Ag, Rh, Pd, Ni, and IrO 2 ), and solid electrolytes (O 2- , F - , Na + , H + conductors), and more recently for aqueous alkaline solutions. In this paper, we show explicitly, on the basis of XPS, TPD, and cyclic voltammetry, that NEMCA is due to the electrochemically controlled back-spillover of promoting species onto the catalytic surface and the concomitant change in catalyst work function and surface chemisorptive properties. This in situ controlled promotion of catalysts underlines the role of the electronic factor in catalysis and allows for a systematic study of the role of promoters.


Generally, employers of private security guards are vicariously liable for the actions of their employees. This incentivizes employers to protect against unnecessary risks to the public and to internalize the social costs of their business activities. In Georgia, however, this centuries-old doctrine of respondeat superior does not apply when a private business hires an off-duty police officer.
Several consequences arise from the current state of the law: inconsistency in application, unfairness to victims and imprudent taxpayer subsidization of private businesses. This Note illustrates that the current law is both unjust and unwise by contrasting business liability for police torts with private citizen torts, and by considering recent cases in which employers escaped liability for the egregious conduct of their employees.
Although the current law is in need of reform, the solution is not radical. Following the lead of several other states and a recent Eleventh Circuit Court of Appeals decision, this Note proposes applying the doctrine of respondeat superior to off-duty officers as a solution that would wholly eliminate the identified problems


The boundary layer stability within the high-area-ratio nozzle at NASA Lewis was tested at five chamber pressure conditions. For all nozzle conditions examined, Taylor-Goertler vortices grew more rapidly than Tollmien-Schlichting waves. The experimental heat flux was accurately predicted by a laminar boundary layer computation, thereby confirming the laminar nature of the nozzle boundary layer flow. When the chamber pressure was increased in a series of cases, the transition point occurred farther upstream. The number of vortices contained in the dominant instability increased with chamber pressure.


In this paper, to improve the testing accuracy of moving objects, the speed attenuation caused by air resistance was introduced into a double-N six-light-screen test system, and the pulse-time axis was recalibrated. Through error analyses of the yaw angle, pitch angle, and axial speed and distance, the advantages of this improved system for testing accuracy were demonstrated. In addition, the reliability of this system was verified through an experimental test with mud pellets. The results show that this system greatly improved the test accuracy of yaw angle and pitch angle, using certain statistical rules for test errors, and the error of the axial speed was only affected by pitch coordinates, while the distance error could reach the nanometer scale, which satisfies our test requirements for small-volume moving objects.

Rietveld analysis of X-ray powder diffraction data was performed on SmBa{sub 4}Cu{sub 3}O{sub 8.5+{delta}}, which was synthesized from precursors Sm{sub 2}O{sub 3}, BaO{sub 2}, and CuO at 1000{degree}C in an oxygen atmosphere. SmBa{sub 4}Cu{sub 3}O{sub 8.5+{delta}} has a cubic perovskite-related structure that is isostructural with YBa{sub 4}Cu{sub 3}O{sub 8.5+{delta}}, and a doubled perovskite unit cell parameter of 8.17790{plus_minus}0.00004{Angstrom}. {copyright} {ital 1997 International Center for Diffraction Data.}


This paper investigates the performance of quadrature-amplitude modulations (QAMs) of different orders with a 2 GBaud symbol rate over a wireless link in the 240 GHz band based on fully-integrated transmitter and receiver chips designed in a 130 nm SiGe technology. The results of end-to-end link measurements at 80 cm distance show the data rates of 4 to 12 Gbps, with an error vector magnitude (EVM) in the range of 7.5 - 8.5 % for all analyzed schemes. Targeting the bit-error-rate (BER) of 10-3, and using 2 GBaud symbol rate, the estimated maximal achievable distances based on the 240 GHz chipset are 3.7 m, 1.4 m, 0.9 m, and 0.7 m for 4-QAM, 16-QAM, 32-QAM, and 64-QAM, respectively. Furthermore, the paper discusses the prospects for throughput boost, using channel combining at an intermediate frequency (IF) as well as deploying Line-of-Sight multiple-input multiple-output (LOS-MIMO). By combining 5 channels and deploying 4×4 LOS-MIMO, depending on the used modulation scheme, data rates of 80 to 240 Gbps are conceivable.


Thomas (1911) founded the genus Millardia on an earlier described species, Golanda meltada Gray, 1837. Subsequently, Ellerman (1941) synonymized the genera Grypomys Thomas, 1911 and Guyia Thomas, 1917 with Millardia, to which they resemble in possessing less than six plantar pads, shortened fifth hind toe and the strongly cuspidate molars. Later, on the basis of his observations on African species of rats he (Ellerman, 1963) accorded the group a subgeneric status under the genus Rattus without assigning any definite reason. Besides the confusion caused by the above conflicting views, the present status of Millardia creates much practical difficulty in identification. Therefore, a critical analysis of various characters of this group has been thought desirable for a clear understanding of its taxonomic position. The present observations are based on the collection present in the Zoological Survey of India, Calcutta, except that of A corny s which have been taken from Miller (1912) and Ellerman (1941, 1963). The external and cranial measurements are in millimetres and after Ellerman (1963). The following abbreviations have been used : HBL., head and body length ; mm., millimetres ; ONL., occipitonasal length ; m, m & m, first, second and third upper molars. The author is thankful to the Director, Zoological Survey of India, Calcutta, for providing facilities for this work and to Dr. B. Biswas, Superintending Zoologist, for suggestions.


In this paper a mutiple linear regression model is applied to global surface temperature records in order to assess the relative contributions of natural and anthropogenic external forcings and internal variability from ENSO, PDO and AMO. The results suggest that variations in the Atlantic merdional overturning circulation (AMOC) has been a significant factor in the decline of global temperatures following 20th century large tropical volcanic eruptions. By neglecting ocean circulation the paper suggest that volcanic cooling after recent volcanic eruptions might have be overestimated by a factor of 2.


Experimental clearings in macroalgal (Ascophyllum nodosum) stands were established in 1996 to determine if mussel beds and macroalgal stands on protected intertidal shores of New England represent alternative community states. Circular clearings 1, 2, 4, and 8 m in diameter were made in Ascophyllum stands at 12 sites on Swan's Island, Maine, USA. Each site also had an uncleared control. The sites are nested within four bays. The purpose of this data set is to provide access to data on densities and percent cover in the 60 experimental plots from 1996 to 2002. Data include densities of mussels (Mytilus edulis and Modiolus modiolus), an herbivorous limpet (Tectura testudinalis), herbivorous snails (Littorina littorea, Littorina obtusata), a predatory snail (Nucella lapillus), a barnacle (Semibalanus balanoides), and fucoid algae (Ascophyllum nodosum and Fucus vesiculosus), and percent cover by mussels, barnacles, and fucoids. Published analyses of the data set show that succession depends on clearing size and not on site-specific differences.

This study investigated the feed handling efficiency and size selectivity of four size groups of Penaeus subtilis fed three commercial feed particle sizes. Shrimp feeding behaviour was recorded with a video‐camera, installed below a glass aquarium, where one shrimp at a time was introduced and allowed to feed. A total of 163 specimens of P. subtilis were examined. Results indicated that over 59% of all food particles placed in the mouth by shrimp were completely or partially consumed, regardless of size. Large pellets however were less preferred than small ones. Manipulation capacity and capture success were also greater when shrimp were fed small particles. Shrimp size had no significant effect on manipulation efficiency, indicating that within the feed size range examined, food handling by juvenile shrimp was as efficient as adults. These results suggest that in aquaculture systems, the use of crumbles and broken pellets may be preferable to large pellets.


The fibre/matrix interaction is a critical aspect of the composite behaviour for all composite families and has to be optimized for each new fibre/matrix system. In order to help this optimization, dedicated tests on model composites have been developed since fibre adhesion to organic matrices was first measured reproducibly in terms of bonding strength in the early sixties. Such tests provide a lot of information about the interface and related microphenomena and thus help to improve the materials. The progress is especially fast whenever the material is in an early stage of development. However, difficulties in the mechanical analysis of those apparently simple tests stand in the way of the introduction of relevant parameters into models of composite behaviour.


Mixed matrix membrane (MMM), a developing research area, is a membrane formed by incorporating fillers in the polymeric membrane to enhance gas separation performance. In this study, MMMs comprised of blend rubbery block copolymers of polyether block amide (Pebax-1657) with a glassy polyethersulfone (PES) polymer and multi-walled carbon nanotubes (MWCNTs) were synthesized by dry phase inversion method and explored further by gas permeability test. Pebax-1657/PES/MWCNTs membrane resulted in an increased permeability as well as CO2/CH4 selectivity. The Pebax-1657/PES polymer blend MMM with 10wt% of MWCNTs has shown the most superior performance of CO2 permeability, CH4 permeability and CO2/CH4 selectivity in comparison with the pure Pebax-1657 resulted in 66.3% and 11.6% difference respectively.


The impact of Ridomil Plus® (12% metalaxyl + 60% cuprous oxide) spray rate and frequency on the severity of potato late blight, caused by Phytophthora infestans, was evaluated during 1997 and 1999 in Dschang, Cameroon. A randomised complete block design was used in both experiments. In 1997, plots were sprayed with 0.6, 1.2, 2.4, or 4.8 kg a.i.ha-1 of Ridomil Plus®, while in 1999, they were treated once, twice or thrice with 2.4 kg a.i.ha-1 of the fungicide. In both trials control plots were not sprayed. Late blight intensity was recorded weekly and yields were obtained at harvest. Fungicide applications reduced late blight intensity and consequently increased potato tuber yields. Marketable yields were significantly higher in the resistant variety, Cipira (22.4 - 34.8 t ha-1), than in the susceptible variety, Tezelfeu (4.0 - 12.0 t ha-1). A significant quadratic relationship existed between the rate or number of fungicide applications and tuber yields. Economic analyses indicated that two sprays of the fungicide at 2.4 kg a.i. ha-1 are necessary for a good late blight protection programme in potato. This spray regime resulted to increases in net returns of US$ 1947 to 3327 ha-1. Results also suggest that high rates or frequencies of fungicide applications do not necessarily lead to better economic benefits.

A external method is developed for determination of fenobucarb and impurity by HPLC with reversed chromatographic column and UV absorbance detector. Results showed the standard deviation was 0.45, 0.03; the coefficient of variation was 0.48%, 3.37%; linear correlation was 0.99993, 0.99991 and recovery was 99.3%~101.05%, 99.6%~102.5%.


There are developed many topological methods which are powerful tools in the theory of critical points of functionals; see for example [2], [3], [5], [6], [9], [13]–[20], [22]–[25], [27]–[29], [32], [33], [43]–[45], [47], [48], [51], [59]. It happens quite often that functionals whose critical points are important in the theory of differential equations are invariant under an action of a compact Lie group G. Symmetric variational nonlinear problems have been considered by many mathematicians; see for instance [7], [8], [10]–[12], [15], [21], [29]–[31], [34], [37], [41], [46], [55]–[57], [62], [63]. In [55] the author has constructed a degree theory for S1-equivariant, orthogonal maps (the known class of S1-equivariant gradient maps is included in the class of S1-equivariant orthogonal maps). Moreover, we have applied this degree to research of bifurcations of solutions of S1-equivariant nonlinear variational problems. For other definitions of degree theories for equivariant gradient maps we refer the reader to [21] (in case of S1-symmetries) and to [37] (in case of symmetries of any compact Lie group). Degree theories for (not gradient) equivariant maps have been constructed in [26], [39], [40].


A novel amphiphilic graft copolymer composed of γ-polyglutamic acid(γ-PGA) as the hydrophilic backbone and cholesterol as the hydrophobic segment was synthesized.The cholesterol-bearing γ-PGA(γ-PGA-Graft-CH) was used to form self-assembly nanoparticles(γ-PGA-Graft-CH NPs) with an inner hydrophobic core and an outer hydrophilic shell via the ultrasonic probe method.The obtained nanoparticles showed low cytotoxicity and a narrow size distribution(PDI=0.17) with a mean diameter 299.6+5.4 nm.OVA-loading γ-PGA-Graft-CH NPs was also successfully prepared,with drug loading content of 118.8μg/mg,and entrapment efficiency of 33.5%.The experimental results also showed that OVA continuously released from γ-PGA-Graft-CH NPs in the phosphate buffered saline(PBS) solutions,and its release was sensitive to the pH of the release medium.


Constrained multibody mechanical systems are used in various applications. These systems often lead to index-2 or index-3 differential-algebraic equations (DAEs), which are known to pose a challenge to numerical integration methods. This paper develops a novel approach to solve index2 DAEs which describe the dynamics of constrained multibody mechanical systems. The method, called PSMAP, relies on effective combination of the power series method (PSM) with Adomian polynomials (AP). To overcome the limitation of the PSM, the PSMAP expands nonlinear terms once in series form using AP. Further, by exploiting an important property of AP, a nonsingular linear algebraic system for the coefficients of the power series solution is derived and solved. To extend the domain of the power series solution, a multistage PSMAP is developed. The main advantage of our technique is that it applies directly to the DAE without the need for complex or costly transformations like index-reductions. Consequently, the PSMAP considerably reduces the computation work, leads to simple algorithm and avoids constraints violation. To demonstrate the efficiency of the PSMAP, two examples of two-link planar robotic systems are solved. Numerical results show that the PSMAP is a powerful tool to solve this class of DAEs. *Corresponding author: E-mail: email@example.com Benhammouda; ARJOM, 8(3): 1-15, 2018; Article no.ARJOM.38983


Under long-term synergy effect of multi-factors, especially the thermal stress, insulating paper will be degraded and its insulation performance will decline due to carbonization and degradation of cellulose. This paper presents an optical approach for aging feature extraction of the insulating paper, where one of the image processing methods called texture analysis is utilized. By conducting laboratory accelerated thermal aging tests, insulating paper samples with different aging conditions for both Nomex and Kraft, evaluated with the aging time, are prepared. After taking optical microscopic images of insulating paper samples belong to different aging groups, up to 14 texture features are extracted using the gray-level co-occurrence matrix (GLCM). With different feature selection methods applied, several of them are finally selected to represent the aging condition of insulating. Numerical tests with both supervised and unsupervised algorithms, as well as a linear regression method verifies the validity of these features in characterizing the aging condition of the insulating paper.


Introduction Species in the genus Aspergillus are saprophytic filamentous fungi that are most commonly found in soil and litter environments of subtropical and warm temperate latitudes [1]. Inhalation of asexual spores produced by Aspergillus fumigatus and a few other species in the genus cause a group of diseases collectively referred to as aspergillosis [2]. The most severe form of aspergillosis is invasive aspergillosis, which primarily affects individuals with compromised immune systems or preexisting lung conditions [3]. Since drugs targeting invasive aspergillosis are not always effective due to our lack of understanding of how they function inside the human host [4] and the evolution of drug resistance [5, 6], infected individuals suffer high morbidity and mortality [7]. Collectively, Aspergillus fungi affect millions of patients and cause hundreds of thousands of life-threatening infections every year [8, 9]. Not all pathogenic Aspergillus species exhibit the same infection rates [10, 11]. Approximately 70% of all Aspergillus infections are caused by A. fumigatus, whereas the remaining 30% of infections stem from other species in the genus [12]. Some of these other pathogenic species–for example, Aspergillus flavus, Aspergillus niger, and Aspergillus terreus–are distantly related to A. fumigatus [12]; each of these three species belong to different Aspergillus sections (note "section" is a taxonomic rank in-between the genus and species ranks) and show extensive genomic divergence [13]. However, there are also pathogenic Aspergillus species, such as Aspergillus lentulus and Aspergillus udagawae, that belong to the same section as A. fumigatus (section Fumigati) and are much more closely related [14–16]. In contrast, the vast majority of Aspergillus species, including many close relatives of the pathogens mentioned above, are either not pathogenic or very rarely cause disease [16, 17]. Interestingly, A. fumigatus and a few other species in the genus can also cause opportunistic infections, mainly in other mammals and birds, and occasionally in other vertebrates and invertebrates [18]. Even though a great deal is known about some aspects of A. fumigatus pathogenicity [2, 19, 20], we have only recently begun to examine why pathogenicity varies so dramatically across the entire genus and the traits and genetic elements that contributed to this variation. Addressing this question requires that we consider the fact that pathogenic Aspergillus species are not


This paper introduces the application of the computer data acquisition and processing technique in the college physics experiment teaching,as an example,the characteristic of PTC and NTC thermal resistor have been measured.


We developed a regio- and stereocontrolled Dieckmann cyclization approach to the synthesis of a novel, natural-product-like scaffold that was inspired from treprostinil (UT-15). This was further utilized in a diversity-based, 15-membered macrocyclic synthesis of two different sets of hybrid compounds. The amino acid moiety embedded in the macrocyclic skeleton allow exploring various chiral side chain groups within the ring.


The apparent permeability of a specific model of a heterogeneous polymer membrane has been estimated by applying a finite-difference method of integration to Fick's first law and the continuity equation. The model was assumed to be a simple chequer one composed of alternate rectangular cells of two different kinds. The cells were defined so as to give repeating concentration profiles under periodic boundary conditions. The apparent permeability of a permeant was calculated from the concentration in sufficiently small lattices in the cell by the iteration method. The effect of membrane heterogeneity or cell dimensions on the permselectivity of permeants is discussed by taking an example, O2+ N2, with polystyrene (PSt)–poly(dimethyl siloxane)(SR) as membrane substrates.


This paper presents three self-powered photodetectors namely, p+-bilayer graphene (BLG)/n+-ZnO nanowires (NWs), p+-BLG/n+-Si NWs/p–-Si and p+-BLG/n+-ZnO NWs/p–-Si. The Silvaco Atlas TCAD software is utilized to characterize the optoelectronic properties of all the devices and is validated by analytical modeling. The proposed dual-junction photodetectors cover broadband spectral response varying from ultraviolet to near-infrared wavelengths. The dual-heterojunction broadband photodetector exhibits photocurrent switching with the rise and fall time of 1.48 and 1.27 ns, respectively. At −0.5 V bias, the highest external quantum efficiency, photocurrent responsivity, specific detectivity, and the lowest noise equivalent power of 71%, 0.28 A W−1, 4.2 × 1012 cmHz1/2 W−1, and 2.59 × 10–17 W, respectively, are found for the dual-heterojunction device with a wavelength of 480 nm at 300 K. The proposed nanowires based photodetectors offer great potential to be utilized as next-generation optoelectronic devices.


The IMP 6 spacecraft was able to make measurements in the distant dayside cusp during substorms when the cusp was located slightly equatorward of its normal location and the geomagnetic dipole was tilted in the appropriate direction. High time resolution data from the magnetic field, plasma, energetic particle, and VLF wave experiments yield support for both reconnection and diffusion as methods of particle entry to the magnetosphere. The support for reconnection is indirect evidence from particles which flow down cusp field lines near the noon meridian. This evidence (1) indicates an acceleration process to explain enhancements of 400 to 600-km/s protons above their magnetosheath intensities and (2) suggests convection of field lines over the polar cap as a means of explaining the lack of low-energy protons near the low-latitude boundary of the cusp. Support for diffusion comes from indications of turbulent flows and fluctuating magnetic fields near the outer boundary of the entry layer. Magnetic field fluctuations below the proton gyrofrequency increase at larger radial distances and higher latitudes within the cusp. Perturbation vector ..delta..B is perpendicular to B in the lower ..beta.. plasma at lower altitudes but is more randomly oriented in the higher ..beta.. plasmas of the distantmore » cusp. Ion cylotron waves are frequently seen in the entry layer and outer cusp. An abrupt change in the intensity of both whistler waves and electrostatic waves near half-integral multiples of the electron gyrofrequency seems to be characteristic of the outer boundary of the cusp. This boundary does not seem to be a standing shock.« less


The present article investigates the phenomenon of compelled circumstantial trust that the public agent is subjected when performing his functions in the Public Administration. This work aims to contribute to the public agent efficiency in the public management field of research. Compelled circumstantial trust is a phenomenon that occurs, for instance, when a mandate has just started, or the public agent is sworn in a new position. Therefore, it is necessary to trust the inherited administrative legacy and its constituent parts, what might represent a potential problem for an efficient public management model, a real challenge for the public agent. This article discusses the presence of the compelled circumstantial trust and presents a validated scale, while presenting a set of best practices aiming at a better performance of the public agent in the exercise of his function, maintaining the constitutional prerogatives and particularities of Public Administration.


Dyslexia is referred as learning disability that causes learner having difficulties in decoding, reading and writing words. This disability associates with learning processing region in the human brain. Activities in this region can be examined using electroencephalogram (EEG) which record electrical activity during learning process. This study looks into performance of Support Vector Machine (SVM) using RBF kernel in classifying EEG signal of Normal, Poor and Capable Dyslexic children during writing words and non-words. Discrete Wavelet Transform (DWT) with Daubechies order 2 was employed to extract the power of beta and theta waves of EEG signal. Beta and Theta/Beta ratio form the input features for classifier.  Multiclass one versus one SVM was used in the classification where RBF kernel parameters and box constraint values were varied with the factor of 10 to analyze performance of the classifier. It was found that the best performance of SVM with 91% overall accuracy was obtained when both kernel scale and box constraint are set to one.

A sensitive search for the rare decays \Omega^- \to \Lambda \pi^- and \Xi^0 \to p \pi^- has been performed using data from the 1997 run of the HyperCP (Fermilab E871) experiment. Limits on other such processes do not exclude the possibility of observable rates for |\Delta S| = 2 nonleptonic hyperon decays, provided the decays occur through parity-odd operators. We obtain the branching-fraction limits B(\Omega^- \to \Lambda \pi^-)< 2.9 x 10^{-6} and B(\Xi^0 \to p \pi^-)< 8.2 x 10^{-6}, both at 90% confidence level.


Large scale urban regeneration projects of central railway stations are considered to be extremely complex. The description and analysis of such projects and the formation of their complexity is becoming difficult as knowledge becomes fragmented among various professionals and "lost" in the course of a decades-long process. Nevertheless, this knowledge is essential for keeping track of the project over long periods of times and might prove useful when such a project is encountered for the first time in any given environment. Such is the case with Prague and Brno railway stations' regeneration projects, that might draw inspiration from similar projects currently being undertaken in London (King's Cross) and Vienna (Hauptbahnhof).


. The article covers the problems of using quantification while analizyng political processes and phenomena, namely the specifics of using quantification in political science. The author pays much attention to such methods of quantification as: scaling and indexing of political phenomena. As a result the conclusion is made that it is necessary to tie up together the measured amount, number, intensity or the degree of the political phenomena manifestations with the analisis of its inner content. The author considers it will help not only avoid accusations in formality and superficiality of the quantification procedure, but also help get the core of the studied political phenomena or process.

Context. Extinction and emission of dust models need for observational constraints to be validated. The coreshine phenomenon has already shown the importance of scattering in the 3 to 5 micron range and its ability to validate dust properties for dense cores. Aims. We want to investigate whether scattering can also play a role at longer wavelengths and to place even tighter constraints on the dust properties. Methods. We analyze the inversion of the Spitzer 8 micron map of the dense molecular cloud L183, to examine the importance of scattering as a potential contributor to the line-of-sight extinction. Results. The column density deduced from the inversion of the 8 micron map, when we neglect scattering, disagrees with all the other column density measurements of the same region. Modeling confirms that scattering at 8 microns is not negligible with an intensity of several hundred kJy per sr. This demonstrates the need of efficiently scattering dust grains at MIR wavelengths up to 8 microns. Coagulated aggregates are good candidates and might also explain the discrepancy at high extinction between E(J-K) et tau(9.7) toward dense molecular clouds. Further investigation requires considering efficiently scattering dust grains including ices as realistic dust models.


Considering that the 316LVM regarded as a medical-grade, is one of the most used biomaterials in the manufacturing of joint prosthesis, due to its low cost, and also its mechanical properties and resistance to corrosion, however, in the presence of body fluids, it degrades, liberating ions to the medium and causing rejection of the implant. An alternative to this phenomenon is to employ coatings of one or more materials that isolate the steel from environmental degradation. In this paper, multilayer coatings of hydroxyapatite/beta-tricalcium phosphate were deposited, with a variation in the number of layers (n=1, 10, 30 and 50 layers) at the constant thickness, to analyze the electrochemical behaviour as the number of layers increases. The scanning electron microscopy technique was used to determine the elemental composition of the multilayers and the Ca/P ratio. Atomic force microscopy analyses were also performed to determine the topography. It is obtained that the corrosion current density, decreases to a greater number of multilayers, offering an improved behaviour in the corrosion processes.


As the complexity of ICs increases at an exponential rate, the cost and time of design has similarly escalated. Among the evolving layout methods to be compared are the use of standard cells, gate arrays, high level symbolic and structured design techniques.


This experimental study concerns the mixed, forced and natural convection heat transfer in rectangular cross-section cavities heated from bottom surface. Flow visualization, temperature profiles and measurements of heat transfer from bottom heating surface are performed for various free-stream velocities, temperature differences between the free-stream and the heating surface and dimensions of the cavity. It is found that flow pattern and amount of convective heat transfer are influenced by an interaction between forced and natural convection, and there is an existence of Reynolds number's region which the amount of convective heat transfer is decreased with increasing Reynolds number. This paper correlates the experimental data in terms of Nusselt number, dimension ratio of cavity (depth/width of cavity), Grashof and Reynolds numbers according to the region of Reynolds numbers.


The aim of this study was to determine the content of some elements (Pb, Cd, Hg, Fe, Cu, Zn, As) in muscle tissue of Prussian carp (Carassius auratus gibelio) from seven different lakes in the Belgrade region, Serbia. Concentrations of Pb, Hg and As in fish muscle tissues from all examined lakes were under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia. In all investigated fish, levels of Cd exceeded maximum allowed concentrations (0.05 mg kg-1). Data on the finding of elements in fish speak concurrently about the safety of fish as food and are good indicators of environmental pollution.


manA is a gene that encode β-mannanase(β-1,4-mannan mannohydrolase EC 188.8.131.52).ManA gene isolated from Bacillus subtilis strain A33 was cloned into an E.coli expression vector pET-32a and be transformed into E.coli strain BL21(DE3).An expression activity 41.58 U/ml was obtained after inducing.To get a better expression level that a site-directed mutation based on PCR was used to induce a mutant β-mannanase gene.The second code of the gene CUU was changed into GUU thus the second amino acid of β-mannanase of N-terminus changed from leucine to valine.The constructed mutated gene vector pET-32a-manA was transformed into strain E.coli BL21(DE3)and induced.The expression activity is increased to 138.65U/ml.It is predicted that a single change of amino acid enhancing the stability of expressed β-mannanase and greatly improve the expression level.The optimum temperature and pH of the enzyme is not changed observably.


Abstract An experimental study of small-scale variability of raindrop size distributions (DSDs) has been carried out at Wallops Island, Virginia. Three Joss–Waldvogel disdrometers were operated at a distance of 0.65, 1.05, and 1.70 km in a nearly straight line. The main purpose of the study was to examine the variability of DSDs and its integral parameters of liquid water content, rainfall, and reflectivity within a 2-km array: a typical size of Cartesian radar pixel. The composite DSD of rain events showed very good agreement among the disdrometers except where there were noticeable differences in midsize and large drops in a few events. For consideration of partial beam filling where the radar pixel was not completely covered by rain, a single disdrometer reported just over 10% more rainy minutes than the rainy minutes when all three disdrometers reported rainfall. Similarly two out of three disdrometers reported 5% more rainy minutes than when all three were reporting rainfall. These percentages were b...


M. C. Beardsley, Aesthetic Welfare, Aesthetic Justice, and Educational Policy, J. Aesth. Ed. 7, 49 (Oct. 1973). This must be called a 'position paper' on some fundamental social, political, moral, economic, religious and educational questions about art. In his characteristic manner of lucid candor, Beardsley distinguishes aesthetic welfare from aesthetic wealth and expands on several themes of the social significance of art and aesthetics. He ends by projecting some fundamental proposals and priorities for educators and public men to ponder. 'If there is such a thing as aesthetic welfare, and such a thing as aesthetic justice, and if they are an important part of a life and of a society worthy of human persons, then aesthetic development must be of very serious concern at all stages of the educational process' (p. 60).

An efficient method of parameter prediction is needed for sensor validation of Space Shuttle main-engine (SSM £) parameters during real-time safety monitoring and post-test analysis. Feedforward neural networks (FFNN) have been used to model the highly nonlinear and dynamic SSME parameters during startup. Due to several problems associated with the use of feedforward networks, radial-basis-function neural networks (RBFNN) were investigated in modeling SSME parameters. In this paper, RBFNNs are used to predict the high-pressure oxidizer turbine discharge temperature, a redlined parameter, during the startup transient. Data from SSME ground test firings were used to train and validate the RBFNNs. The performance of the RBFNN model is compared with that of a FFNN model, trained with the Quickprop learning algorithm. In comparison with the FFNN model, the RBFNNbased model was found to be more robust against variations in architecture and network parameters, and was faster to train. In addition, the performance of the RBFNN model during nominal operation and during simulated input sensor failures was found to be robust in the presence of small deviations in the input.


This study aims to determine the effect of the use of multimedia learning English vocabulary to student learning outcomes. The method used in this study is a one-group pretest-posttest design. Type one group pretest-posttest design was intended to be the result of treatment can be determined more accurately, because it can be compared with the situation before being treated. The instrument used in this study is shaped in the form of test questions pretest and posttest. Learning outcomes data obtained by performing tests in the form of essays. Questions used during the pretest and posttest is exactly the same problem. This is due to find out the differences or improving student learning outcomes before and after different treatment between these two classes. Learning outcomes data obtained by performing tests in the form of essays.

This shows that the use of multimedia learning positive effects.


In the present investigation the influence of a constant level of P excess (890 mg/MJ ME) was examined in 20 European shorthair cats using the following
study design:
1.) a Ca/P-ratio in the recommended range (1.3:1)
2.) an inverse Ca/P ratio (0.4:1) according to Pastoor (1993) and
3.) a high Na and marginal K supply as well as an inverse Ca/P-ratio (0.4:1).
Selected parameters of renal health including endogenous creatinine clearance, serum chemistry, urine analysis as well as faecal and renal mineral excretion were
determined. In both trials with inverse Ca/P-ratio the endogenous creatinine clearance was significantly reduced and therefore confirmed the findings of Pastoor (1993). Furthermore, renal protein and glucose excretion increased. All effects were aggravated by multiple inappropriate mineral supply (Na excess and marginal K supply). Feeding the P excess diet with balanced Ca supply (Ca/P=1.3:1) for the limited study period of 28 days did not lead to comparably altered clinical findings. Possible long-term effects under these conditions can not be assessed on the basis of the current results.

The imprecise computation technique ensures that all time-critical tasks produce their results before their deadlines by trading off the quality of the results for the computation time requirements of the tasks. This paper provides an overVIew of the problems in scheduling imprecise computations. It describes several workload models of imprecise computation that explicitly characterize the costs and benefits of the tradeoff and the scheduling algorithms that have been developed to achieve the desired tradeoff.


. We argue that interstellar gas in elliptical galaxies can be turbulent, with turbulent scale and velocity of 400 pc and 20kms~ 1 re spectively. An upper limit on turbulent velocity, ~ 50kms _1 , follows from the requirement that the turbulence dissipation rate does not exceed the X-ray gas luminosity. The turbulence can generate random magnetic fields of 0.3 /xG strength at the above scale via fluctuation dynamo ac tion. The resulting Faraday rotation is random, with a typical value of 5-30 radm~ 2 , consistent with observational evidence available.


The SIFT (Scale Invariant Feature Transform) is a most popular image processing algorithm that has been widely used in solving image matching related problems. However, SIFT is of high computational complexity and large memory requirement that prevent it from being applied to applications that are unable to offer large on-chip memory. Based on the analysis of the memory requirement of SIFT feature detection, a novel memory access strategy is proposed to reduce the hardware memory usage. In addition, to achieve real-time performance of high resolution video streams, dedicated hardware architecture with multi-pixel based processing scheme has been developed. Compared with conventional designs, our design achieves hardware memory reduction of at least 58.8%.


Both pediatric and adult malignant intraocular ocular tumors are often treated with external beam radiation or brachytherapy. Because the lens is the most radiosensitive ocular structure, cataracts are a common occurrence after such treatments. Some studies report up to an 87% occurrence of cataracts within 3 years in retinoblastoma patients treated with external beam radiation (Blach et al., 1996; Fontanesi et al., 1996). In the Collaborative Ocular Melanoma Study, the largest multicenter prospective randomized trial ever performed for uveal melanoma patients, 83% of patients had developed cataracts by 5 years post-treatment (Collaborative Ocular Melanoma Study Group, 2007). Because many patients treated for intraocular tumors survive for extended periods and have the capacity for excellent vision, cataract surgery is an important part of the treatment algorithm for these patients. However, this group of patients poses a unique set of surgical challenges not present in standard cataract patients. In this chapter, we will review the incidence, surgical techniques, visual and anatomic outcomes, and complications for this unique group of patients.


This paper deals with the study of wastewater production, municipal treatment plants performance, and utilization of treated wastewater in the southeast of Coahuila, Mexico. The objective is to identify the status of wastewater in order to propose alternatives to increase the use of treated wastewater. Influent and effluent on three municipal wastewater treatment plants were analyzed considering four parameters. Results show that the wastewater presents a high concentration of total suspended solids; nevertheless the effluents meet the current environmental standards. Then the treated wastewater requires additional treatment before to be applied in industrial processes, but it can be used for irrigation purposes.


ABSTRACT Relatively little has been written about the detailed workings of the court of chancery after the restoration. Even less is known about the doctrines of the chancery in the eighteenth century. Yet social historians of this period have relied on legal sources to generate a narrative which suggests that the landed classes were instrumental in determining the content of the rules governing family settlements. This article seeks to situate that narrative in the adjudicative context. Through a close textual analysis of the case law, supplemented by archival material, the article argues that, whilst successive chancellors did give voice to the underlying intentions of the settlor (and thus to the estate preservative policies of their class), the settlor's intention was not the sole prescribing law when construing family settlements.

In this paper, we analyze the effect of cyber-attacks on voltage control via the Wide Area Monitoring, Protection and Control System. To address this problem, we model wide area voltage control as a dynamical system under the presence of an adversary that aims to disrupt the network's voltage and steer the system towards voltage collapse. Under this framework, we derive stealthy attack templates that aim to reveal the attack locations and timing that will be most effective on the power grid. From the perspective of defending the grid, the attack templates reveal the critical locations for the optimal distribution of resources to mitigate potential cyber-attacks. Alternatively, we derive stealthy attack templates based on power flow equations and the static mechanism of voltage collapse. The effectiveness of our proposed attack templates are validated through numerical examples.

During the last decades, the term postmodernity has been highly invoked, on the one hand, or ignored, on the other hand. It is a term that can be found in the writings of various philosophers and sociologists, and is almost ignored and less meaningful within the economic thinking. At first view and analysis, postmodernity is the successor of the modern age, modernity in other words. However, the concept has much deeper meanings; it regards the future, foreshadowing the new realities of today's world, which are very complex and dynamic, and come under endogenous and exogenous influences, activities and issues that are permanently under the influence of multiple and multidimensional challenges [7]. In fact, the period of globalization, of the new trends of the revolutionary ICT (Information and Communication Technologies), is believed to overlap the period of postmodernism. From the philosophical point of view, but also in consonance with the economic life and realities, the individuals and entities of any nature should be characterized by adaptability, the ability to respond promptly and appropriately to the impulses and reactions that affect that system .
