Various ecological waste treatment and utilization systems (EWTUS) available in urban and rural areas in China are described, among which are land treatment and utilization systems (LTUS), eco-pond systems mainly consisting of macrohydrophytes-growing ponds, fish ponds and duck/geese ponds, and comprehensive circulation eco–systems for the treatment and utilization of wastes in rural areas, such as semi–closed eco–system in fish ponds, "rice–fish" and "rice–azolla–fish" symbiotic systems, recycling eco–systems with methane-generating digesters as central link, and comprehensive recycling eco–systems with digesters and eco–ponds as central link. In the various EWTUS, the sewage and wastewaters and other wastes are utilized and converted into various forms of recoverable resources and/or energy, while they are being purified to good quality effluents, meeting their respective discharge standards, and hence acceptable to receiving waters.


Solving the algebra equation with real_coefficients of nth degree is of great importance for analysis and synthesis of a control system A few methods, such as Splitting Trinomial Factor method and the Optimal Trinomial Factor method proposed firstly in this paper, can be used to solve the algebra equation with complex roots of nth degree.This paper proposes that the Optimal Trinomial Factor method is superior to Splitting Trinomial Factor method in convergence,accuracy and other variables.The Optimal Trinomial Factor method is based on the factor that a real_coefficient polynomial of high degree can always be the product of several trinomials and a sub_polynomial whose degree is 4 or 3. Getting all trinomials and a sub_polynomial of the original algebra equation, the solution is obtained.OTF has satisfying accuracy for engineering practice and is superior to STF in iteration numbers. Five examples were selected from testing examples for the effectiveness, accuracy and convergence of OTF. They are suitable instances in illustration of properties of OTF: effectiveness to compute all of complex and/or real roots of an equation, satisfying accuracy of obtained roots.


Objective: Vasculitides are heterogeneous group of disorders that feature inflammation of the blood vessels. The aim of this study was to investigate the role of TNF-α, MMP9 and the balance between Th17 and Tregs in two ANCA negative vasculitides, polyarteritis nodosa (PAN) and Behçet disease. Methods: Peripheral blood lymphocytes were isolated from three patients with childhood PAN, four with Behçet disease and three controls. mRNA levels of FoxP3, IL-17, TNF-α and MMP9 were studied by qRT-PCR and analyzed as described previously. Results: IL-17, MMP9, TNF-α expressions were significantly increased compared to normal controls (p=0.0322, p=0.0011, and p=0.0235 respectively) in both diseases. There was no difference in the expression for FoxP3. Conclusion: Our results suggest that Th17 cells participate in the inflammation of PAN and Behçet disease. Increased expressions of TNF-α and MMP9 suggest their role in the pathogenesis as well.

by Nei! Harms and Perpetua Rodriguez Oafeguards measures at the world's light-watercooled reactors (LWRs) — the major type of nuclear power reactor in use today for the production of electricity — are well established. More than 220 LWRs and other types of power reactors presently are under IAEA safeguards in non-nuclear weapon States.* This article addresses current IAEA safeguards practices at LWRs and also safeguards measures under consideration and development that go beyond the practices of today. Why does the IAEA implement safeguards at nuclear power plants? How are these facilities a threat to nuclear proliferation? To answer these questions, it is important to look at the kind of nuclear materials at nuclear power plants. Excluding the use of mixed uranium-plutonium oxide (MOX) fuels for the moment, LWRs use low-enriched uranium (LEU), categorized as "indirect-use" material from the standpoint of its potential use in the manufacture of nuclear weapons. After these nuclear materials have been fueled in the reactor core, the spent fuels are categorized as "direct-use" material. Plutonium contained in spent fuel, as well as fresh MOX fuels, represent a strategic material from a safeguards standpoint. This is one of the determining factors that affects the safeguards approach and the inspection goal for a facility.


The tradition of outstanding corrosion resistance of titanium alloys in seawater environments continues with Ti 5111 (ASTM Grade 32, UNS R55111). Assemblies of Ti 5111 and ofTi 5111 galvanically coupled to Alloy 625 have now been crevice corrosion tested in natural seawater for one year. No crevice corrosion was observed on Ti 5111:Ti 5111 and Ti 5111:Alloy 625 assemblies after one year submersion in seawater. The alloy's resistance to environmentally assisted cracking in seawater with applied cathodic potentials and sustained load cracking in air has also been investigated. The tests confirmed that Ti 5111 has excellent resistance to sustained load cracking in air and environmentally assisted cracking in seawater with applied potentials of -1.0 or -0.45V Ag/AgCl , yielding a threshold K SLC (= K EAC ) of 105 ± 2 MPa.m 1/2 (96 ± 2 ksi.in 1/2 ). Fracture surfaces are ductile transgranular with no evidence of stress corrosion cracking. Ti 5111's resistance to stress corrosion cracking and crevice corrosion in seawater environments and galvanic compatibility with Alloy 625, make it an ideal material for high strength marine fastener applications. Other tests, with potential downhole applications in mind, were carried out in flowing aerated seawater, at elevated temperature, with and without CO 2 and CO 2 /H 2 S additions to evaluate the suitability ofTi 5111 as a candidate tubular material for water injection string applications. No corrosion of any kind was observed on Ti 5111 under injection conditions of mixed commingled seawater with produced water, rendering the alloy suitable as a candidate tubular material for water injection string applications.


NE group, 89% were intubated and 56.9% developed seizures within 24 hours of delivery. There were no deaths in the control group but 23.9% of infants died in the NE group. Women in the NE group were more likely to exhibit a category II or III FHR tracing at the time of admission than were women in the control group. In the 30 minutes before delivery, category III FHR tracings were more common among women in the NE group (19 women, 17.4%) compared with 2 women (0.9%) in the control group. Of interest most FHR tracings were category II before delivery regardless of group. Compared with controls, women in the NE group were more likely to demonstrate minimal or absent variability, bradycardia, late decelerations, and prolonged decelerations before delivery. In summary, the results of the study suggest an association between certain FHR patterns and development of NE. In addition, an increased focus on variability and the presence of late and prolonged decelerations may improve the management of category II tracings. The authors support further investigation into how obstetric management in response to FHR patterns may mitigate adverse neonatal outcomes.


Although the strengths perspective seems a natural framework for social workers practicing in mental health, it often plays a minor role in planning and evaluation. Two issues complicate its use: (a) The concept of strengths has different meanings and functions, depending on whether viewed as part of assessment, intervention, or outcome, and (b) the strengths perspective is an applied concept operating only through the medium of a specific intervention, not a modality whose efficacy can be independently evaluated. When these factors are ignored, the role of the strengths perspective can seem vague, peripheral, too obvious and "soft" to be a serious component of the change process–-yet, understood in context, it is an essential element of social work's unique approach.


The growing global epidemic of coronavirus, as well as the shortage in health care professionals, impose protection measures to be taken by citizens themselves. One of these measures is social distancing. In an autonomous and assisted living environment a set of technologies can offer protection to the tenants by monitoring the individuals' distance between them. This paper proposes to leverage the social distancing application in Ambient assisted living environments, following the precautions proposed by the experts against Covid-19. The evaluation results were quite impressive and a high accuracy was achieved as the difference between application's and real world measurements was up to 5%.


This article deals with the relationship between music and festive practices. After having delimited the idea of Fiesta from an anthropological point of view, the author traces the main types of different musical manifestations as they appear in festivals and celebrations. The last part of the article seeks to explain the importance of music in festive practices basically through the fact of the extreme complicity of music with the four constants, formulated by Vittorio Lanternari, regarding the idea of Fiesta : sociability, participation, rituality and the temporal and simbolic annulment of order.


The passenger car air conditioning system is designed to supply and process fresh air, prevent it from the spread of infections and pathogenic bacteria through disinfection as well as provide com-fortable conditions for train passengers and personnel. The prime requirement for air conditioning systems in railway transport is the stability of parameters set to maintain microclimate in the train, regardless of meteorological conditions. One of the tasks facing the SLE in railway transport is to minimize the energy consumption of the air conditioner. This is due to the fact that a voltage of 220 V and lower is used to power the air conditioner, which can be obtained either from the contact network or from batteries on the train. Each kilowatt of low-voltage electricity is quite expensive, an order of magnitude more expensive than in a stationary location, and this is due to the increased attention to the energy consumption of SLE. The article proposes a method and conditions for calculating indirect evaporative cooling of passenger car air conditioning systems in order to reduce energy consumption, increase reliability and comfort of passenger transportation. 2672-8575 © 2022 Published by European Publisher.


A novel membrane deflection technique (MDT) was designed to investigate the fracture toughness of MEMS materials. The specimens were notched using a focused ion beam (FIB) milling method to produce pre-existing cracks with a tip radius as small as 50 nm. The fracture behavior of ultrananocrystalline diamond (UNCD) developed at Argonne National Laboratory has been investigated using this methodology. 15 UNCD thin film membranes with the gauge size of 200 μm in length, 20 μm in width, and 800 nm in thickness were tested under tensile stress until failure. Measured fracture toughness (KC) values were found to be 6.8-7.3 MPa m with the crack size varying from 1 μm to 5 μm, indicating that the fracture toughness is independent of the geometry.


In recent years, researchers have been attracted to the application of wide-bandgap (WBG) power semiconductor devices such as silicon carbide (SiC) and gallium nitride (GaN) in electric vehicle (EV) applications. Their advantages over Si power semiconductors are lower power losses, higher switching frequencies, and higher junction temperatures. Thus, using WBG power semiconductor devices for EV power electronic systems improves EV efficiency, reliability, and mileage; however, these adoptions are still under challenges in terms of packaging and power converters design. In this article, future trends and prospects of using WBG power semiconductor devices in EV systems are first presented. Then, the recent progress of different commercial WBG power semiconductor devices is reviewed and different solutions are reported to overcome R&D obstacles.


Online learning contexts promote pedagogical changes to foster students' success and prevent dropout. Teacher and student roles are expected to be redefined to fit the characteristics inherent in the status of teacher and students. Teaching should promote student autonomy, which, according to Holec's (1981) [1] definition, implies the ability to take responsibility for learning. This focus on the student requires the development of competences at the level of self-regulation of learning and metacognitive strategies. That is, setting goals for learning objectives, identifying and developing appropriate strategies, reflecting on their learning, assessing their own progress. It was with this framework that we developed our work. We used a sample of 62 1st cycle students of both sexes who attend online course. It served as a basis for our work by Cubukcu (2009) [2]. The results point to the differentiation of teacher and student roles. However, the most indicated strategies are those that are less related to a reflection on learning. As a conclusion, we point to need a student to approach their strategies for greater autonomy.


SUMMARY

Viscosity readings with three rates of shear for each of six time intervals were obtained for 0.5% dispersions of lambda-carrageenan in de-ionized water and in solutions of increasing concentrations of CH3COOK, KBr, K2CO3, KCl, K3C3H5O7, KNO3, K3C2O4, K3PO4, and K2SO4. The addition of any of these salts to the water in which lambda-carrageenan was dispersed caused a highly significant decrease in viscosity. Significant differences also occurred among the viscosity readings for lambda-carrageenan dispersed in different concentrations of one salt; however, the same concentrations of the different salts did not show comparable effects on the reduction of carrageenan viscosity. No significant differences occurred among viscosity readings for carrageenan dispersed in the various potassium salts at the 0.05N level of concentrations nevertheless, differences did occur at both the 0.10N and 0.20N levels of concentration. All solutions tested showed significant differences among viscosity readings due to rate of shear. Differences were minimal among viscosity values attributable to aging time of the dispersions.

In order to provide a basis for better understanding of phylogenetic relationships of Saudi Arabian Tetraena Maxim. and Zygophyllum L., 44 specimens representing seven taxa, were reconstructed based on chloroplast DNA data of rbc L and trn L-F. The combined chloroplast ( rbc L and trn L-F) contributed more phylogenetically informative characters than in individual regions. Phylogenetic analysis of the combined chloroplast ( rbc L and trn L-F) and in individual regions based on both of Maximum Parsimony and Bayesian criteria showed that the Saudi Arabian species of Tetraena and Zygophyllum were monophyletic. Zygophyllum fabag L. was nested in one clade with Z. xanthoxylum (Bunge) Engl. (Asian species), and all taxa of Tetraena were distributed in other clades. Bangladesh J. Plant Taxon. 24 (2): 155–164.


In this paper the residual stresses in a butt-welded plate of 2.25Cr 1Mo has been analyzed using a 3D and transient finite element (FE) model. Also the effect of the welding-electrode speed has been studied using death and birth of FEs. For this purpose, a coupled thermo-mechanical FE solution has been used to obtain the temperature distribution and the resulting residual stresses. Also, the variations of the physical properties of the material with temperature have been taken into account. Results show that the residual stresses in the heat affected zone (HAZ) are maximum and change along the weld and also in the plate-thickness. It has been shown that use of the 3D and transient model will lead to more accurate and realistic results which are well compared with the experimental test data.


Gluon radiation is an important mechanism for parton energy loss as the parton traverses the quark gluon plasma (QGP) medium. We studied the gluon emission in QGP using AMY formalism. In the present work, we obtained gluon emission amplitude {\bf F}({\bf h},p,k) function, which is a solution of the integral equations describing gluon radiation including Landau-Pomeranchuk-Migdal (LPM) effects, using iterations method. We define a new dynamical scale for gluon emission denoted by $x$. The gluon emission rate is obtained by integrating these amplitude function over {\bf h}. We show that these obey a simple scaling in terms of this dynamical variable $x$. We define the gluon emission function $g(x)$ for gluon radiation for the three processes $g\rightarrow gg$, $q\rightarrow gq$ and $g\rightarrow q\bar{q}$. In terms of this $g(x)$ function, the parton energy loss calculations, due to medium induced gluon radiation, may become simplified.


We formulate a delayed SIR epidemic model by introducing a latent period into susceptible, and infectious individuals in incidence rate . This new reformulation provides a reasonable role of incubation period on the dynamics of SIR epidemic model. We show that if the basic reproduction number, denoted, R0, is less than unity, the disease- free equilibrium is locally asymptotically stable. Moreover, we prove that if R0 > 1, the endemic equilibrium is locally asymptotically stable. In the end some numerical simulations are given to compare our model with existing model.


The aim. To evaluate the effectiveness of the diagnosis of senile asthenia using the Edmonton Frail scale in emergency abdominal surgery and to determine its impact on the severity of the perioperative period.
Materials and methods. The study included 81 patients with acute cholecystitis on the background of gallstone disease, who were assessed for senile asthenia using the Edmonton Frail scale. For the reliability of the obtained results, only patients who were urgently hospitalized to the surgical department with gynecology beds of the emergency hospital with clinical symptoms of acute cholecystitis were included. All patients received treatment in only one department and according to the standards and clinical protocols of this clinic. Based on the Edmonton Frail score, all patients were divided into two groups. The comparison group included 50 (61.7 %) patients who did not have senile asthenia. The main group included 31 (38.3 %) patients diagnosed with senile asthenia.
Results. Surgical treatment in both groups was carried out on an urgent basis using total intravenous anesthesia with artificial lung ventilation. According to the type of surgical intervention in both groups, preference was given to minimally invasive methods. Laparoscopic cholecystectomy in the comparison group was performed in 49 (98.0 %) patients, and only one patient (2.0 %) was converted and operation continued from the mini-access. In the main group, all surgical interventions were performed by the laparoscopic method, U = 759.50, P = 0.8841. Analyzing the results of the duration parameters and the need for prolonged mechanical ventilation, it can be seen that it progressively increases in patients with asthenia: in the comparison group 61.50 (48.00; 75.00) minutes, and in the main 93.84 (60.00; 80.00), U = 513.50, P = 0.0112. Also, we noted that in patients with senile asthenia, the number of postoperative complications increases: in the comparison group, there were only 2 (4.0 %) postoperative complications, while in the main group – 7 (22.6 %), U = 556.00, Р = 0.0337.
Summarizing the results, it can be seen that due to increase of the frequency of postoperative complications and increase of the need for prolonged artificial ventilation of the lungs, the length of hospital stay of patients with senile asthenia increased: in the comparison group it was 7.9 ± 2.2 days, and in the main group 9.7 ± 3.2 days, U = 530.50, P = 0.0177.
Conclusions. In our opinion, the Edmonton Frail scale is effective in diagnosing the severity of senile asthenia in elderly and senile patients in emergency abdominal surgery due to its simplicity and speed of use. The overall severity of the condition, heart failure in patients with senile asthenia lead to increase in the duration of surgery and the total duration of artificial lung ventilation: in the comparison group 39.52 (30.00; 45.00) minutes, while in the main group 49.19 (35.00; 50.00) minutes, U = 482.50, P = 0.0046. The duration of mechanical ventilation also differed significantly, in the comparison group 61.50 (48.00; 75.00) minutes, and in the main – 93.84 (60.00; 80.00), U = 513.50, P = 0.0112. The severity of senile asthenia negatively affects the course of the perioperative period, the frequency of postoperative complications increases: 2 (4.0 %) patients in the comparison group, while in the main group of 7 (22.6 %) patients, U = 556.00, P = 0.0337 and, as a consequence, the duration of inpatient treatment increases: in the comparison group it was 7.9 ± 2.2 days, in the main – 9.7 ± 3.2, U = 530.50, P = 0.0177. Modification of the approaches to preoperative preparation and postoperative management of elderly and senile patients diagnosed with senile asthenia will reduce the frequency of postoperative complications and reduce the length of hospital stay.


Extant country-of-origin research has focused on the deliberate use of country-specific associations (CSAs) as a cognitive cue, captured by consumer responses to direct questioning. However, such responses only capture rational and verbally held aspects of CSAs and do not reveal emotional and nonverbally held aspects. Drawing from dual-coding theory, the authors (1) develop propositions about the existence of two distinct types of CSAs (rational and emotional) and the differences in consumers' communication of these associations, (2) apply a three-stage qualitative design in two complementary studies to test these propositions, (3) link the identified CSAs to brand origin recognition and brand ownership, and (4) generate a consumer typology on how CSAs are communicated. Their results indicate that people tend to communicate rational CSAs verbally and emotional CSAs nonverbally. Whereas both rational and emotional associations positively affect consumers' brand origin recognition accuracy, only emotional associations affect brand ownership. The authors consider theoretical and managerial implications in light of recent criticism on country-of-origin research and offer suggestions for further research.


Results are given of write—disturb—read tests on elements of continuous film of 80Ni17Fe3Co on aluminum substrates. The curves relating output voltages to digit currents used for writing and disturbing are traced automatically. Measurements on a variety of films show that, irrespective of whether Hc/HK≶1 the following statements apply to 40‐mil‐square elements: the disturbing threshold current is about 1.5 times the value calculated; the writing threshold is usually about 3 times the value calculated; the output of one polarity may fall very rapidly as skew increases; creep occurs during about the first 100 disturbing pulses; even with optimum digit currents the disturbing pulses can reduce the output and may even just reverse it. However, where the reversed output is small a two‐element storage cell can be made to give correct operation. The ultimate limit of skew occurs when the writing threshold approaches the disturbing threshold, so that films with higher Hc/HK tolerate more skew. Films with Hc/HK>1 ...

Carravetta Institute for Cancer Treatment and Research, BARI, Italy Introduction: Central venous access positioning and its management represent one of the achievements in a cancer patient. Moreover, the prevention and the control of catheter related complications are the main objectives for any Cancer Institutes. To support the dressing's management of the cancer patients with central venous access, the Institute for Cancer Treatment and Research of BARI in ITALY, proposes a training session and a continuous collaboration between medical and nursing staff, caregivers and patients. Method: During the first dressing the patient is informed about the complications of central venous catheter and the good practices for the dressing's management. Moreover, the patient receives a checklist of the catheter related injury and the devices recommended by international guideline. Then the patient is invited to photograph any change of dressing and to send these pictures to a dedicated email address. The dressing's management outpatient evaluates the pictures and publish the most significant photos on the site of the Cancer Institute. Results: The daily review of central venous access assessed by a photographic archive improved by the dressing's management outpatient in hospital and by the patients at home. This photographic documentation can be updated (daily, if necessary) by the patient or the caregiver in case of suspected catheter related complications. Discussion and conclusion: The introduction of a photographic archive and the collaboration between patient and caregiver improve the prophylaxis of the catheter related complications and promote the good practices in the central venous access management.

association with sociodemographic factors, lifestyle and other comorbidities. METHODS: Cross-sectional population-based study with a probabilistic sample of elderly in Goiânia, Goiás, Brazil. RESULTS: Of the 934 elderly, 19.0% self-reported DM and 13.9% overweight. The prevalence of DM and overweight was higher among females, on those aged 60-69 years, among people who self-reported good health and were not physically active (overweight). There was an association and a high prevalence of hypertension, hypertriglyceridemia and hypercholesterolemia. CONCLUSION: The prevalence of self-reported diabetes and excess weight was high. Their association with comorbidities also with high prevalence is a condition that negatively affects the living habits of this vulnerable population, requiring actions to promote health for these people.


We present a global-in-radius linear analysis of the axisymmetric magnetorotational instability (MRI) in a collisional magnetized plasma with Braginskii viscosity. For a galactic angular velocity profile $\Omega$ we obtain analytic solutions for three magnetic field orientations: purely azimuthal, purely vertical and slightly pitched (almost azimuthal). In the first two cases the Braginskii viscosity damps otherwise neutrally stable modes, and reduces the growth rate of the MRI respectively. In the final case the Braginskii viscosity makes the MRI up to $2\sqrt{2}$ times faster than its inviscid counterpart, even for \emph{asymptotically small} pitch angles. We investigate the transition between the Lorentz-force-dominated and the Braginskii viscosity-dominated regimes in terms of a parameter $\sim \Omega \nub/B^2$ where $\nub$ is the viscous coefficient and $B$ the Alfv\'en speed. In the limit where the parameter is small and large respectively we recover the inviscid MRI and the magnetoviscous instability (MVI). We obtain asymptotic expressions for the approach to these limits, and find the Braginskii viscosity can magnify the effects of azimuthal hoop tension (the growth rate becomes complex) by over an order of magnitude. We discuss the relevance of our results to the local approximation, galaxies and other magnetized astrophysical plasmas. Our results should prove useful for benchmarking codes in global geometries.


The research purpose was the study of rear and endangered species of the family Caryophyllaceae Juss. in the Altai Mountain Country (AMC). The objectives involved the identification of rare and endangered species of the family and the analysis of their limiting factors. The studies were conducted in the period from 2004 to 2012. The research material included our own observations of the species in the natural conditions and herbarium samples from the AMC. Eleven species of the Caryophyllaceae Juss. family from the AMC are protected on the federal and regional levels. Those species are in the Red Lists of Threatened Species of the following countries and regions: Russian Federation, Mongolia, Republic of Altai, and Kemerovo, Krasnoyarsk and Altai Regions. All limiting factors were analyzed, and two major factors affecting the whole family were revealed. The main reason of including the species in the Red Lists is an increasing anthropogenic impact. The first limiting factor is the impossibility of further dissemination causing the loss of the populations and species. The second limiting factor is the stenotopy of the species (a low competitive ability, blowing of the seeds from the phytocenosis, and the adaptation to restricted conditions (wind, temperature). It is proposed to include the following species in the Red Lists: Arenaria pentandra Maxim. (Republic of Kazakhstan), Dianthus soongoricus Schischk., Gypsophila cephalotes (Schrenk) Will., Silene altaica Pers., Silene mongolica Maxim., Stellaria pulvinata Grub. (Mongolia). It is proposed to exclude Stellaria dichotoma L. from the "Red List" of Mongolia due to its wide distribution.


Advancements in construction are concentrated largely on producing innovative practices to perform construction projects in an efficient and timely manner. Understanding the relationship between performance on the job site and level of productivity is important to develop best and innovative practices to improve construction productivity. This paper explains the ongoing research project within Alberta construction industry to identify the most critical aspects in terms of human, external and management issues that affect construction productivity. The pilot study interviewed very experienced personnel from the construction sector not only to prioritize the factors but also to identify the measurement criteria to improve future construction projects. The second phase of the research and the deliverables are also outlined in the paper.


In Western music, Orientalist styles have related to previous Orientalist styles rather than to Eastern ethnic practices, just as myths have been described by L6vi-Strauss as relating to other myths.1 One might ask if it is necessary to know anything about Eastern musical practices; for the most part, it seems that only a knowledge of Orientalist signifiers is required. In the case of Orientalist operas, I had at first thought it might be important to understand where they were set geographically. Then I began to realize that, for the most part, all I needed to know was the simple fact that they were set in exotic, foreign places. Perhaps I should have remembered Edward Said's advice that "we need not look for correspondence between the language used to depict the Orient and the Orient itself, not so much because the language is inaccurate but because it is not even trying to be accurate. What it is trying to do ... is at one and the same time to characterize the Orient as alien and to incorporate it schematically on a theatrical stage whose audience, manager, and actors are for Europe, and only for Europe."2 Nevertheless, the state of affairs found in a work like Rameau's Les Indes galantes (1735), where, for example, Persians are musically indistinguishable from Peruvians, was to change. Distinctions and differences developed in the representation of the exotic or cultural Other, and that, as well as the confusion that sometimes results, is my present concern. This confusion is most evident in the nineteenth century, when Western composers, especially those working in countries engaged in imperialist expansion, were torn between, on the one hand, making a simple distinction between Western Self and Oriental Other, and on the other, recognizing that there was no single homogeneous Oriental culture. Thus, even when different Orientalist styles had become established, they could sometimes be applied in a careless manner. In this article, because of its broad span, I am looking primarily for changes in representation. As a caveat, I should stress that in a genealogical critique such as this, a smooth linear narrative is impossible, and owing to the contingent nature of developments in Orientalist styles, a certain amount of lurching around on my part is unavoidable.


Disturbances of bone and mineral metabolism are a hallmark of chronic kidney disease (CKD). Renal osteodystrophy (ROD) is the traditional term for bone lesions in conjunction with CKD and is now considered a part of the 'chronic kidney disease—mineral and bone disorder' (CKD-MBD) [1]. ROD comprises various subtypes with substantial differences in aetiology and fundamental differences in treatment strategies. In long-term dialysis patients the prevalence of some types of ROD is virtually 100% [2]. A simple, easy to apply but still sophisticated and comprehensive descriptive system of ROD is the TMV system [1]. The TMV system comprises bone turnover (T), bone mineralization (M) as well as bone volume (V). Bone turnover and bone volume may both be classified as high, normal or low. Bone mineralization may be categorized as normal or abnormal. As an alternative to volume, the bone balance may be considered [3,4]. Based on the above system, the NKF/KDOQI guidelines distinguish six types of bone pathology in CKD-MBD (Table 1) (Figures 1 and 2). The focus on cancellous bone parameters in this classification system has been questioned regarding the importance of cortical bone quality for structural integrity [5]. Moreover, bone histomorphometric parameters comprise a continuum, and categorization may be an oversimplified approach [5]. Nevertheless, categorical CKD-MBD classification is helpful for clinical practice and widely used as the basis for therapeutic decision making. In this review we will focus particularly on adynamic bone disease (ABD), which is increasing in prevalence and, in


Unconsumed food has environmental impacts via both the resources used in food production and its disposal. Ideally, householders would generate only unavoidable food waste such as preparation residues and peelings. Reducing avoidable food needs underpinning evidence to ensure that initiatives to alter householders' behaviour deliver their intended outcomes. The aim of this work was to better understand means to reduce avoidable food waste by establishing where attention should be focused, and whether campaigns to change householders' behaviour should focus on the financial or environmental impacts of food waste. Analysis of food waste composition in relation to households' economic status was combined with field trials of interventions, which established that (1) interventions had negligible impacts on food waste composition, and (2) most avoidable food waste comprises fruit, vegetables, bread, and prepared meals. The focus for initiatives to reduce food waste is thus clear, but the potential for information-based campaigns to reduce food waste appears limited


An experiment was performed using 20 calves of about one-month old to investigate the effect of chelation therapy with calcium disodium ethylenediaminetetraacetate (CaNa 2 EDTA) alone or along with antioxidant α-tocopherolin lead loaded calves on blood trace minerals, erythrocytic sulfahydryl groups and some haematobiochemical parameters. Fifteen calves were given lead orally at a daily dose of 7.5 mg of 99% pure lead acetate/kg body weight for 28 days. Then the lead was withdrawn on day 28 and the calves were randomly divided into three groups. Each group of five animals was either treated with CaNa 2 EDTA alone at the dose rate of 110 mg/kg body weight in two divided doses for 4 days or along with α-tocopherol at the dose rate of 100 mg/kg body weight orally daily for 7 days, keeping the remaining five calves as lead-exposed untreated controls. Blood samples were collected at the end of the lead exposure (day 0) and thereafter on day 2, 4, 7 and 10 from the start of the chelation treatment. The treatment with EDTA alone led to slow but non-significant improvement in blood copper level, but incorporation of antioxidant α-tocopherol in chelation therapy resulted in its significant decline, as recorded on day 7-post treatment. Withdrawal of lead or treatment with CaNa 2 EDTA alone or along with α-tocopherol enhanced the erythrocytic thiol contents and the levels of T-SH and P-SH became statistically (p 0.05) change in serum urea, creatinine, total protein and albumin levels between the treatment groups. It is concluded from the present investigation that treatment with CaNa 2 EDTA at the present dose rate is safe to be used for chelation in lead loaded calves.

Computer Vision is a concept which works with the methods for automatic extraction, analysis and understanding of useful information from a single image or a sequence of images. To fulfill the new challenges, the system which is proposed in this paper, is mainly being used for object detection and recognition of images so that the image search engine becomes more fruitful. A large dataset of 15 million high-resolution images have been taken from ImageNet with more than 21K different classes to the purpose of object detection and recognition system for image search engine which have been trained through machine learning. TensorFlow is an open source library for software which uses machine learning techniques as Convolution Neural Network to train datasets and to provide the percentage accuracy of objects in an image. The datasets have been trained so that the objects can be detected and figured out. The trained datasets create a protocol buffer (.pb) file which ensures the serialization of datasets according to their classes for matching the patterns. For giving input as well as viewing the result with best guesses, it has been designed a demo image search engine using Laravel5.4 framework of PHP language. By uploading several images on the demo image search engine, best guesses can be shown where the input image matches the pattern with protocol buffer file to provide the output results. There has been achieved highest accuracy rate of 99.983% best guesses and lowest accuracy rate of 89.282% best guesses for this proposed system which is better than the previous state-of-art.


This invention relates to a method for preparing an antibiotic stinking-proof textile, which comprises the following steps: 1) preparing A finishing liquid including AgNO3, penetrant and dispersing preservative; 2) immersing the textile in the A liquid by pad mangle; 3) preparing B finishing liquid including reducer and dye leveler; 4) immersing the textile in the B liquid by the pad mangle and reacting to generate the nanometer silver particles; 5) cleaning the finishing liquid not reacted; 6) drying and shaping. The penetration, dispersing protection, reduction and equalizing technology are all proceeding in the liquid, by which the compounded nanometer silver particles can be absorbed and penetrated in the surface and gap of the textile evenly.


The operational characteristics of a light expanded clay aggregate (LECA) media biofilter treating the odorous off gases from the cooking process of a rendering facility were investigated. Over the course of a 20 month period odour removal efficiencies ranged from 63.2% to 98.2%. Lower efficiencies were observed when the media in the biofilter was changed. The new media was inadequate and had to be replaced again to achieve the desired odour removal efficiencies. When the biofilter media was adequate the odour removal efficiencies were generally above 90% and often above 95%. Inlet odour concentrations ranged from 7,100 ouE m-3 to 233,536 ouE m-3. The biofilter was capable of reducing high and low odour concentrations efficiently. The empty bed retention time of the biofilter varied between 25 and 47 seconds. It was desirable to achieve an EBRT close to 35 seconds during warmer periods of the year when odour concentrations were higher. The biofilter moisture content at 400 mm deep ranged from 33.4% to 59.6%. Deeper in the biofilter at 900 mm, moisture content ranged from 34.5% to 44.7%. It was desirable to keep the moisture content between 40% and 45% although during autumn test dates moisture content was lower than 40% and efficiency remained high. The pH of the biofilter ranged from 6.4 to 9.6 at 400 mm and 6.0 to 9.4 at 900 mm deep. Ideally, pH should be maintained between 7 and 8.


Empirical evapotranspiration models were used in computing onset dates, termination dates and duration of growing season. Other rainfall data (daily, monthly, and annual) were analyzed using several statistical methods. The onset dates were determined using rainfall data and evapotranspiration models developed by Kowal and Knabe (1972), Blaney-Morin Nigeria (BMN) (Duru 1984), Penman (1948) and Walter (1967), while the termination dates were determined using a model developed by Zargina (1987). Climatological data were obtained from the Institute for Agricultural Research (IAR), Ahmadu Bello University (ABU), Zaria database, for twenty years of daily data (1981 – 2000). Using Blaney-Morin Nigeria (Duru 1984) model, the mean onset date during the period of study is 26 th April and the earliest starts are 23 rd April and 6 th June, respectively. Rainfall terminates in the month of October. The result shows that about two third of the onset dates are in May and the rainfall regime is marked by a peak in August with about 24% of the annual total rainfall received in this month. The comparison, shows that Walter (1967) and Blaney-Morin Nigeria (Duru 1984) models predict earlier onset than Penman (1948) model while Penman (1948) predicts late termination than the other two models. Therefore, Walter (1967) and Penman (1948) have longer length of growing season than BMN (Duru 1984).

This paper describes the design of a novel dynamic Content Addressable Memory (CAM) cell suitable for high density arrays on the order of 64K bits. The proposed cell is capable of storing three internal states; '1', '0' and "don't care" (MASK). The cell consists of five NMOS transistors of which four are used to store and access data and one is used as a diode to isolate current paths. Charge is stored on the gate of a transistor which results in non-destructive current driven Read and Match operations and increases the charge storage time leading to higher reliability and improved immunization to alpha particles. Using 2µm design rules, buried contacts, single level metal, and low resistance polycide lines results in a CAM cell 25µm × 22µm which is comparable to 64K bit static RAM cell areas. The CAM cell was sucessfully fabricated using a 4µm NMOS process and its operation was confirmed with a 2 × 3 bit array.


There is a series of adaptive feature of D. luodian ense in population level. It has high shoot-emergen ce number, high mortality and low bamboo grown-up rate. The shortag e of nutrition is the main reason for the high mort ality. In the distribution of D. luodianense, the age structure o f the population is growing, but it tends to be sta ble. There is a great relationship between the distribution pattern and the sampling scale. With the increase of resea rch scale, the clonal distribution pattern changes from random to cluster-based type, and the clonal ramets distribut ion pattern is an enhanced cluster-based type. The population regu lation of D. luodianense belongs to density depende nce type, which is affected by clonal density and clonal rame ts density. The environment capacity of D. luodiane nse is about 100/m 2 .


Iodination of N-methylquinaldinium iodide gives N-methylquinaldinium tri-iodide which with silver nitrate affords quinoline-2-aldehyde methiodide. A possible mechanism is advanced. Iodination of N-methyl-lepidinium iodide similarly yields N-methyl-lepidinium tri-iodide, but in this case silver nitrate treatment gives no aldehyde. Excess of iodine results in the diamagnetic bis(N-methyl-lepidinium)octa-iodide. The evidence obtained from absorption spectra and electrical conductivity measurements regarding ionic and intraionic dissociation of N-methylquinolinium polyiodides is discussed.


Our propositional-attitude concepts are indispensable to us; our very survival depends on the ways we use those concepts to exploit others as sources of information about the extra-cranial world and to predict and explain our own and other people's behavior. If, as many suppose, to have a propositional attitude is to stand in a propositional-attitude relation to a proposition, then we should find that propositions play an essential role in enabling propositional-attitude concepts to perform the jobs they perform for us, and if we found that things of some other kind—say, linguistic entities of some stripe or other—could do what propositions do better than, or even as well as, propositions, then we should doubt whether propositional attitudes really are relations to propositions. In this article I inventory the jobs that our propositional-attitude concepts do for us and explain how propositions enable them to do those jobs and why things of no other kind could enable them to do those jobs nearly as well as propositions do. I also show that, among propositions, fine-grained material-object-dependent propositions are much better enablers than propositions of any other kind. If my arguments are correct, then Davidsonians and others should give up trying to hold that propositional attitudes are relations to linguistic entities, and Stalnakerians and others should give up trying to hold that the propositions we believe and assert can be represented as sets of possible worlds. Although there is a vast literature on whether propositional attitudes are relations to propositions, a crucial question that ought to lie at the heart of this debate is not often enough seriously addressed. This is the question of the contribution propositions make to the ways in which we benefit from having our propositional-attitude concepts, if those concepts are concepts of relations to propositions. Unless propositions can be shown to confer a benefit that no non-propositions could provide, we should probably doubt whether propositional attitudes really are relations to propositions. I believe that propositional attitudes are relations to propositions and that the role played by them in our conceptual economy cannot be played by things of any other kind, and in this article I try to say why. This article, in other words, offers my answer to the question posed by my title. 1

Abstract Objective: To date, no prospective comparative study of the diagnostic value of STIR versus T1-weighted (T1w) sequences at both 1.5 T and 3 T has been performed with special focus on the detectability of bone metastases. Materials and Methods: 212 oncological patients had a whole-body MRI at 1.5 T and/or at 3 T. The standard protocol comprised STIR and T1w sequences. All patients who showed typical signs of bone metastases were included in the study. Evaluation of the images was performed by the calculation of the number of metastases by three independent readers and by visual assessment on a 4-point scale. Results: 86 patients fulfilled the inclusion criteria. The total number of metastases was significantly higher on T1w than on STIR images at both field strengths (p < 0.05). T1w revealed a sensitivity of 99.72 % (3 T) and 100.00 % (1.5 T) versus STIR with 70.99 % (3 T) and 79.34 % (1.5 T). In 53 % (38/72) of all patients, STIR detected fewer bone metastases in comparison with T1w at 3 T. At 1.5 T, STIR showed inferior results in 37.5 % (18/48) of all patients. Qualitative analysis indicated a significantly better lesion conspicuity, lesion delineation and an improved image quality on T1w compared to STIR imaging at both field strengths (p < 0.05) with similar results for T1w at 1.5 T and 3 T, but inferior results for STIR especially at 3 T. Conclusion: The whole-body MRI protocol for the detection of bone metastases could safely be limited to the T1w sequence in adults, especially at 3 T. There is no need for an additional STIR sequence. These initial results will have a major impact on the department's workflow if confirmed by larger studies as they will help reduce examination time and therefore save financial resources. Key points: • In a routine MR protocol, T1w imaging is sufficient for the detection of bone metastases. • In case of differential diagnostic problems, other appropriate sequences can be added to the protocol. • STIR is inferior to T1w in the detection of metastases, especially at 3 T.

Bulk heterojunction (BHJ) solar cells have made great progress over the past decade and consequently are now attracting extensive academic and commercial interest because of their potential advantages: lightweight, flexible, low cost, and high-throughput production. Polymer conductivity is a key factor for improving the performance of electronic and photonic devices. Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is promising for use as a next-generation transparent electrode of optoelectronic devices. In this research, we compare the effect of nanomorphology on conductivity, and power conversion efficiency of polymer organic solar cells prepared by the spin- and spray-coating methods. To improve the conductivity of spray-deposited PEDOT:PSS, we modified the PEDOT:PSS films by simple UV irradiation and by UV irradiation with treatment using various solvents such as methanol, ethanol, acetone, acetonitrile, hydrochloric acid, and sulfuric acid to form a hole transport layer (HTL). The active layer of PTB7:PC70BM is spray-coated on top of the PEDOT:PSS layer. The films were examined by optical spectroscopy, micro-Raman spectroscopy, and conductivity measurements. The surface morphology of the deposited films was examined by atomic force microscopy (AFM). The current density–voltage (J–V) characteristics were measured under illumination with simulated solar light at 100 mW/cm2 (AM 1.5G) using an oriel 1000 W solar simulator. The obtained results are expected to have a considerable impact and suggest a bright future for organic polymer solar cells.


In theory, a book's ISBN is unique. Garnet Publishing, a small publisher specialising in the Middle East, appears to have taken a short-cut with Mohammed's Islamonomics, however, and has given it the same identity number as his 2018 title, What Is Islamic Finance, and Why Should We Care? I dug a little to see if it is actually the same book with a catchier name, and that does indeed seem to be the case, albeit with some tweaks.


Research on performance simulation deployment opportunities in the building operation phase has recently gained on momentum. Specifically, simulation routines have been successfully applied in the conception and implementation of predictive methods for building systems control. Needless to say, the quality of such a predictive control system depends on the reliability of the integrated simulation models. Thus, to ensure that predictions are dependable, the incorporated simulation models must be calibrated. Moreover, given the dynamic nature of building operation and the boundary conditions, some input parameters of the model may have to be subjected to calibration more frequently. Hence, the calibration task cannot be approached as a one-time activity. Rather, it needs to be conducted on a regular and systematic basis. Given this background, this paper examines the potential of recurrent optimization-based simulation model calibration of an office area. The results displayed a noticeable but not fully consistent improvement of the predictive potency of the calibrated model.


Counterproductive work behavior (CWB) is a things that can harm the industry and co-workers, CWB can be an abuse, production deviance, sabotage and theft, and even withdrawal. Many factors can cause CWB, one of them is the personality type. The dark triad personality regarded as the dark side of personality that the researched is rare in Indonesia. The purpose of this study was to determine whether there was any influence of each dark triad personality traits (machiavellianism, narcissism, and psychopathy) on counterproductive work behavior. This research uses total sampling technique in a production field of the printing company and fruit chip company with 56 subject, using Short Dark Triad Scale (SD3) and Counterproductive Work Behavior Checklist (CWB-C). The Result found that the machiavellianism and narcissism has no significant effect on CWB. While the psychopathy are significant against CWB.


The Golden Jezebel (Delias aruna) is a large pierid butterfly known in Australia from Torres Strait and from Cape York to the McIlwraith Range, with most sightings in the Iron Range area. This paper records a new southern record, and thus a possible extension of range, in Rinyirru (Lakefield) National Park some 100 km south-east of previous records and in quite different habit at to normal.


Background and Objectives: Using additives such as Balnkit, to increasing the quality color of food and for the fermentation and early preparation of bread dough, has increased in recent years. The purpose of this study was to investigate the concentration of Blankit in Hamadan breads production and risk assessment of food consumption during 2016. Materials and Methods: In this descriptive-analytical study, Balnkit, concentration in breads produced in Hamadan in 2016 was determined. A total number of 85 samples were randomly collected from all bakeries in two steps. The concentration of Blankit was determined according to ISIRI guideline using spectrophotometer in 560 nm. Then for the evaluation of risk assessment of food consumption, the value of target hazard quotients (THQ) was calculated. Results: The Blankit was not found in 97% of samples and only 3% of samples (Lavash bread) have the Blankit. The calculation of the THQ index showed that value of THQ was 0.0041 whose value is less than 1 and the consumption of bread with this concentration will not endanger. Conclusions: The results of this study showed that the addition of Blankitin bread processing, with regard to the concentrations determined and eliminating it from bread due to the heat, does not pose a threat to the health of the people.


There are many good reasons to ensure sufficient exercise in everyday life. However, advising patients with increased blood pressure (hypertension) to exercise regularly is often regarded as a specific medical measure aiming to reduce the increased risk of late complications. But whether more exercise actually helps to avoid illnesses related to hypertension or at least delay their onset has been insufficiently investigated.


This document was previously referred to as the Draft 2006 Plan. As part of the DOE`s national strategy, the Richland Operations Office`s Paths to Closure summarizes an integrated path forward for environmental cleanup at the Hanford Site. The Hanford Site underwent a concerted effort between 1994 and 1996 to accelerate the cleanup of the Site. These efforts are reflected in the current Site Baseline. This document describes the current Site Baseline and suggests strategies for further improvements in scope, schedule and cost. The Environmental Management program decided to change the name of the draft strategy and the document describing it in response to a series of stakeholder concerns, including the practicality of achieving widespread cleanup by 2006. Also, EM was concerned that calling the document a plan could be misconstrued to be a proposal by DOE or a decision-making document. The change in name, however, does not diminish the 2006 vision. To that end, Paths to Closure retains a focus on 2006, which serves as a point in time around which objectives and goals are established.


This paper addresses software dependency by presenting a multi-kernel-based software model and introducing the concept of directional coupling (d-coupling). A six-level d-coupling model to represent the dependencies of a kernel module on other modules in a multi-kernel-based software system is defined. This model can be used to represent the dependencies induced by all types of software coupling. The dependency model is applied to evaluate Darwin, a dual-kernel-based operating system. The study shows that (1) few strong dependencies exist between Darwin kernel modules and other modules; (2) from version XNU-517 to XNU-792, Darwin has been restructured to reduce the number of high level dependent modules induced by high level global variables to mitigate the effect of the increase of the dependency due to the growth of the kernel size and the product size. 1. INTRODUCTION omponent-based software engineering is the production of software products through the systematic integration of existing software components. Quite frequently, existing components are not like ready-to-use building blocks, especially in the case of large-scale design-level reuse. Instead, these components need to be modified to meet the specific requirements of the new product. Furthermore, reused software components also need to be updated to meet new requirements or changes in the environment. Therefore, reusability and maintainability are two important properties of a software component [1. [2]. A considerable amount of work has been done to try to characterize reusable [3–7] and maintainable [8–10] software components. Both reusability and maintainability are related to coupling. If a software component is relatively independent, that is, if there are only a few dependencies of this component on other components, it would be easy to understand, maintain, and reuse this component. Coupling reflects the modifiability, maintainability, and reusability of a software product [11]. Certain types of coupling, especially common coupling, are considered to present risks for software development, reuse, and maintenance [12–15]. Hence, a maintainable and reusable component should be as independent as possible.


Electrical submersible pump providers are always collaborating with client to overcome the challenges of costly ESP change out by offshore workover rigs and the conventional well intervention by offshore barges, in addition to the harsh reservoir environments due to high H2S and high temperature. Accordingly, operating companies are keen to minimize the number of ESP failures and avoid costly offshore workovers especially in high producers and when the demand of production is high. In effort to improve the ESP reliability and ensure continuous production, several recent technologies were combined to boost the run life of the overall completion.
 The combination of these technologies improved the run life and the reliability of the system and resulted in massive financial impact as it saves rig cost, Barge cost, wireline cost, operations cost and more importantly the deferred production.
 This paper will elaborate in details about the technologies utilized in this completion and how it caused considerable financial impact on both vendor and client.


A numerical and analytical investigation of the formation and structure of thin current sheets which form in a magnetotail-like plasma model is presented. Current sheet formation is driven by the application of a boundary electric field similar to what would be expected from solar wind driving. As a result, a thin current sheet forms which involves strong Hall-type electric fields, which, by means of electric field drifts, strongly increase the electron contribution, and reduce the ion contribution to the cross-tail current density. This result is also supported by analytical investigations of the total plasma momentum. The thin current sheet forms on strong gradients in the ion density and the magnetic field. The simulation leads to a well defined equilibrium state.

Background: Microelemental content of the hair reflects the status of microelements in whole body and is an indicator of mineral metabolism. There is no sufficient literature on study of macro and microelements in HIV/AIDS. We study macro and micro elements in hair samples of HIV infected patients and healthy individuals. Materials and methods: We collected samples from 100 people aged 21 – 55. 40 persons were healthy, 46 were HIV infected. HIV infected patients have been divided into 3 groups according to CD4 cells count: more than 500, 200 – 499, less than 200. Neutron activation analysis (NAA) was used to detect microelements in the hair. Results: Our study revealed the following results: in HIV infected women levels of Cl, Fe , Co, Ni, Cu, K, Se, Br, Rb, Ag, Cd, Sb, Ba, As were lower than in healthy persons. Levels of I, Au,Hg, Sr were higher than in healthy persons, Cr, Mn, Zn, U levels were normal. Levels of K was decreased 5 times and Ni was decreased 2 times compare to norm. In male HIV patients, the results were different: the levels of , Cr. Mn. Zn,Se, Br, Au, Sb, Ba were normal, levels of Сl, Ca, Fe, Co, Ni, Cu, K, Rb, Ag, Cd, Hb, U were lower compare to healthy people. Only Iodine (I) and Strontium (Sr) were higher than norm. Conclusion: Analysis of our data revealed that HIV infected patient develop deficiency of some macro and micro element (Sc, Cr, Fe, Cu, K, Se, Rb, Sb, Cd, Hg, As). The causes of such disbalance are due to changes in microbiocenosis of intestines and an impaired absorption in progression of HIV/AIDS. Found disbalance of microelements in hair samples of HIV infected patients defines necessity of correction of deficiency of macro and micro elements in treatment of such patient. It necessitates further detailed research of such disturbances to better understand immunopathochemical nature of HIV/AIDS and goal oriented therapy.


In this paper,the effect of hot-air drying conditions on the texture and sensory characteristics of Cantonese sausage was tested by texture profile analysis combined with sensory evaluation.The results showed that:increase of drying time obviously reduced moisture content of products,increased the hardness,springiness,gumminess and chewiness value of products,but showed little effect on the improvement of products.Increasing the drying temperature obviously reduced water content of the product,and also greatly improved its texture characteristics,including its hardness,springiness,and chewiness.The degree of drying temperature influence on texture characteristics of the product was related to the temperature-related phase during drying process.It was also found that hot-air drying conditions showed great influence on the sensory quality of the Cantonese sausage.


A new predictable model of the generation of municipal solid waste (MSW) is established by combining GM(1,1) model and GM(1,N) model. By using GM (1, N) model to do the quantitative analysis on the main factors of the generation of MSW, and using GM (1, 1) model to analyse and predict each factor,the relationship between the various factors and the generation of MSW and the new predictable model of the generation of MSW are obtained. We took the data of Shanghai as the example to establish the combinatorial model. It is analysed that the model's fitting precision and predictable precision are higher. The method has good feasibility and practicability, and provides a quantitative basis for analysing, forecasting and planning management of MSW.


The general situation of public welfare of the disabled(PWD) in China has been greatly improved,but the ethical defence of PWD isn't sufficient. A practical defence model should be constructed so that all generally ethical principles will be reduced to ethical strategies. And finally, all sorts of limitation on PWD in practice will be revealed.


A crystal and molecular structure determination of the transition metal-nucleotide complex, Ni(imp)(H2O)5,2H2O shows that the octahedral nickel ion is co-ordinated to the N(7) atom of the hypoxanthine unit and to five water molecules and that hydrogen bonding occurs between two of the co-ordinated water molecules and two of the phosphate oxygen atoms; the structure previously proposed is shown to be incorrect.

Parkinson's disease (PD) is characterized by motor and nonmotor features, including cognitive, neuropsychiatric, and autonomic disturbances. PD can also be accompanied by various pathological behaviors such as pathological hypersexuality (PHS), excessive gambling or shopping. These impulse control behaviors have devastating psychosocial consequences. Recently, PHS has been associated with antiparkinsonian medication. However, the brain region responsible for PHS remains unknown, in part because of few neuroimaging studies. We describe a PD patient with PHS who showed activation in the medial temporal regions on technetium-99m-ethyl cysteinate dimer (Tc-ECD) SPECT. In October 2001, a 74-year-old right-handed man noticed gait difficulty and hand tremor. He received levodopa, and symptoms improved moderately. However, slowness of movements, rigidity, and tremor worsened, and he was given other antiparkinsonian medications, including pergolide and trihexyphenidyl. In March 2006, he presented at our hospital. The patient was given L-dopa (300 mg/day), pergolide (1500 lg/day), selegiline (5 mg/day), trihexyphenidyl (2 mg/ day), and droxydopa (200 mg/day). He showed features of moderate Parkinsonism, including masked face, stooped posture, retropulsion, bradykinesia, left-side-dominant rigidity, and resting tremor. Because slowness of movement and gait difficulty progressively worsened, the doses of L-dopa (400 mg/day) and pergolide (1,750 lg/day) were increased. Symptom severity decreased, but obsessive behavior developed in February 2008. Every night he demanded sex several times and touched his wife's genitals many times per night, even though he could not achieve an erection. He was uninterested in other women. He also changed clothes many times per day. The patient had a serious personality, with no history of hypersexuality. In March, his sexual urges increased despite treatment with quetiapine (25 mg/day). In April, he desired sex constantly, not only at night but also during the daytime. The results of EEG and cranial MRI examinations were normal. The easy Z-score imaging system (eZIS) images on initial Tc-ECD SPECT showed increased regional cerebral blood flow (rCBF) in the right medial temporal regions (Fig. 1A). There was decreased rCBF in the occipital lobes (data not shown). At the time of SPECT imaging, the patient was receiving L-dopa (400 mg/day), pergolide (1,750 lg/day), selegiline (5 mg/day), trihexyphenidyl (2 mg/day), droxydopa (200 mg/day), and quetiapine (25 mg/ day). The scores of neuropsychological assessments were 1 (out of a possible 54) on the Hamilton Depression Scale, 3 (out of 56) on the Hamilton Anxiety Scale, and (3 out of 60) on the Young Mania Rating Scale. The score on the Mini-Mental Status Examination was normal (26/30). The scores on parts I, II, III, and IV of the Unified Parkinson's Disease Rating Scale were 0, 7, 14, and 1, respectively. The dose of only pergolide was decreased (1,250 lg/day), and the obsessive touching of his wife's genitals and excessive punding-like behavior resolved, but he still demanded sex many times per day. In May, the dose of pergolide was decreased to 500 lg/day. The doses of the other medications remained unchanged. His desire to have sex resolved during the daytime, but persisted at night. At the time, a second series of eZIS images on SPECT revealed that the increased rCBF in the right medial temporal regions had diminished (Fig. 1B). PHS in our patient was ascribed to pergolide since such behavior decreased after lowering the dose. Impulse control behavior involves increased dopaminergic stimulation of nonmotor basal ganglia loops, including the nucleus accumbens, mesolimbic and mesocortical circuits, and the anterior cingulate loop. Dopamine agonists can influence nonmotor basal ganglia loops. Dopamine D3 receptor is involved in reward, craving, emotional, and cognitive processes and related to impulse control behavior. Pergolide has a high affinity for D3 receptor. The relation of drug usage to PHS remains uncertain, but the association of pathological gambling in PD with the use of dopamine D3-selective agonists and our observations suggest a link between PHS and treatment with this type of drug. The region responsible for PHS remains unclear because of difficulty in evaluating the underlying causes by techniques such as functional MRI. Some neuroimaging studies of impulse control behavior showed reduced activity in the mesial frontal areas in medicated PD patients performing the Iowa Gambling task. Functional MRI showed a negative correlation of gambling severity with activation of the ventromedial prefrontal cortex and ventral striatum in individuals with pathological gambling without PD. The increased medial temporal blood flow in our patient may provide initial evidence of primary regions associated with PHS. The mesolimbic system, an integral part of nonmotor basal ganglia loops, regulates responses to natural rewards such as sex. The dopamine D3 receptors, temporally associated with PHS in our patient, are primarily localized to brain limbic regions. Although the effects of other antiparkinsonian medications being received at the time of scanning cannot be ruled out, our observations suggest that excessive stimulation of D3 receptors in medial temporal regions may contribute to PHS in PD.


Japan and the United States have mature, defined benefit Social Security systems that provide a basic level of income to most retired workers. The retirement benefit in both countries is determined using an earnings based benefit formula. Japan has a separate benefit that provides a specified yen amount for all persons plus an earnings benefit. Current law specifies that the benefit formula will ultimately be 0.7125 percent of earnings for each year of covered employment. In the United States, there is no flat benefit; however, the benefit formula is progressive and provides a greater proportionate benefit to low-wage workers. For a person reaching age 62 in 2003, benefits are determined using a formula that provides 90 percent of the first $606 of average indexed monthly earnings (AIME), plus 32 percent of the next $3,047 of AIME, plus 15 percent of AIME in excess of $3,653. Both countries provide nearly universal coverage and workers who have average earnings and have a full career of participation in the system will receive a retirement benefit that is 40 to 50 percent of their average earnings. The Social Security systems of both countries are facing significant long range funding problems. Important policy debates concerning how to modify these programs are occurring in both countries. Current projections indicate that to pay benefits specified under current law the payroll tax for the Japanese system would have to increase from its current level of 13.58 percent of annual earnings to 23.1 percent in the next 25 years. In the United States, the cost of Old Age Survivors and Disability (OASDI) is projected to rise from 10.9 percent in 2003 to 20.1 percent in 2080. The income rate for these programs is approximately 13 percent of covered payroll. Thus the projected shortfall in revenues in 2080 is projected to be over 6 percent of payroll (Board of Trustees, 2003). Confronted with these financial realities, policy makers are debating how to reduce future costs of providing retirement benefits or identifying methods of increasing future revenues. The debates in both countries are wide ranging and include many policy options. This paper provides an assessment of the debate in the United States and discusses its implications for reform in Japan.


Seabather's eruption (SBE) is an acute dermatitis caused contact due to with the scyphomedusae Linuche unguiculata, and L. aquila and, rarely, the sea anemone Edwardsiella lineata.t is manifested by erythematous and itchy papules located often in areas covered by bathing suits during or immediately after exposure to sea water. We report two cases of SBE mimicking Koebner Phenomenon (KP) as envenomations caused by the hydromedusa Olindias sambaquiensis and the scyphomedusa Chrysaora lactea, some of the most common jellyfish species in S and SE Brazil.


All teachers are leaders by the nature of their work. They lead within their schools, whether implicitly or explicitly, for good or for bad, proactively or reactively. In this chapter, we present a framework of teacher leadership that is an assemblage of our previously published works. We use this chapter to provide a consolidated view of how to help all teachers to acknowledge, understand, and use their "awesome" power as leaders to transform their classrooms, schools, and communities. Schools are sites of social, political, and economic influence and teachers play key roles in either maintaining the status quo or creating environments that are transformative and equitable for all members. We argue that a teacher's power is essential both within and beyond the walls of the classroom. Teachers have the capacity and power to participate in change decisions and efforts that traditionally either have been tacitly assumed by them or deliberately defined by others. By having an understanding of critical leadership or leadership for social justice, teachers will be more prepared to identify and resist the variety of contexts which threaten their professional expertise and contexts that deliberately question their professional knowledge.

The article provides a comprehensive analysis of the social policy of American Conservatives in the end of the 20th century. The context for this study is the protracted "crisis of the welfare state" that the entire Western world has experienced. An evaluation of the adaptation process of American Conservatism to this rapidly changing world constitutes an innovative research task of this work. The social policy advocated by the American Conservative movement is analyzed not as a reaction to liberal politics and sequence of unrelated actions, but as a self-sufficient strategy. There are strong arguments to put forward a research hypothesis that the 1990s was a period when the Conservative model of social politics was created as an alternative to the socio-liberal model. In other words, it is a conservative version of a "welfare state" that has become the main expression of social policy. An additional innovative aspect of this work is its analysis of the interconnection of Conservative social policy and the evolution of the Conservative movement itself. In the "Contract with America" and the "compassionate conservatism" program the Republicans managed to achieve synthesis of principles and approaches of different kinds of the conservative movement. For the first time, they were able to create a conservative version of the "welfare state."


Poetics can be defined as a system of a poetic creation which is beyond a physical state. In other words, we can say that Poetics stands for a metaphysical state of a poetic creation. Its chief concern is not only the creation of a poem rather to highlight linguistic features, cultural values and dialogues, as well as literary discourse. The basic motif of analysis of any literary creation is to associate it with the basis of literature, but the conscious creation of a literary genre has an inherent sub-conscious creation in its core depth, like; social, historical and cultural patterns.

This book creatively explores the gold rushes in the Tasman World through an examination of the Otago gold rushes. It adopts a new methodology to reveal how transnational connections and local social and natural environments shaped colonial identities. The first monograph-length study on the Otago gold rushes and their place in the histories of British and Irish migration, it further increases our understanding of the British World by grounding transnational networks in the local ecologies, geologies and weather patterns which shaped local social structures and profoundly affected migrants' relationships to loved ones in Britain, Ireland and elsewhere. In doing so, Gold Rush Societies evolves as neither a local nor a transnational history but one which blends the two into a single study and offers fresh perspectives on each in the process.


The catchword of young people refers mainly creates,transformation,use,promoted dissemination by the young people,and in the young people use the popular words and expressions widely,this is the production of young people which are the kind of rich vigor but simultaneously the insufficiently stable mature mass organization seeks the self-approval and the difference characteristic inevitable.In the young people catchword has one kind of limit language,this kind of limit language main reflection is calling in the three aspects of the eulogy,the degree adverb,the degree complement.They often adopt such solid ways as righteousness substitution,novel usage,superior combination and fast elimination to express one kind of high and limit semantics.


In the beginning of this millennium power density and related heating problems practically stopped the exponential frequency increase of single core processors and limited availability of instruction-level parallelism (ILP) in general purpose applications started to limit the speedup achievable by increasing the number of simultaneously executed instructions in superscalar processors that along with architectural improvements in exploitation of memory hierarchies used to roughly duplicate the performance of processors in every second year for decades. In order to be able to continue the increasing trend of computational performance, all major processor manufacturers have switched to chip multiprocessors (CMP) integrating multiple processor cores on a single chip and switching the focus of parallelism from ILP to thread-level parallelism (TLP), because the number of transistors per chip still tends to increase exponentially with every new generation of silicon technology (ITRS, 2007) and high amounts of TLP is easier to extract than ILP. Manufacturers have ambitious plans to continue this development by roughly duplicating the number of cores per chip every second year, resulting to constellations with over 100 cores in ten years (Intel, 2006). This will, however, not happen without problems, because current CMP architectures and related programming models do not support simple migration to parallel computing, so called automatic parallelization of existing sequential code has been turned out to be extremely difficult for general purpose programs, writing explicitly parallel versions of programs has turned out to be tedious, error-prone and expensive, and achieving linear speed-ups with respect to the number of cores appears to be limited to only small classes of well-behaving algorithms. These problems are caused by inability of current architectures to hide the latency of shared memory accesses (or intercommunication), lack of synchronicity in execution of computational threads as well as too weak models and low-level primitives of parallel computing forcing a programmer to explicitly take care of data partitioning to maximize locality, functionality mapping supporting data partitioning, synchronization of subtasks, and communication. Without solving these problems, it is hard to imagine that parallel computing would be able to 3


A brief review of the indirect detection signatures of dark matter is given. In particular, detection methods of dark matter particle annihilation to antimatter and γ-rays are reviewed. With the GLAST satellite soon to be launched, a crucial window in the energy range of a few GeV up to 300 GeV will open. The good angular and energy resolution of the instrument means that structures predicted by cold dark matter models can be searched for. Large, currently planned ground-based imaging Cherenkov telescope arrays, may further improve the limits, or discover a signal, if the current understanding of halo dark matter structure is correct.


Along with popularity of electronic commerce and online purchasing, electronic payment systems have been developed and expected to the main payment means of e-commerce. But many of electronic payment systems have failed with a short-lived time. From the standpoint of buyers, this paper discusses the influential factors of electronic payment system adoption and classifies these influential factors into six dimensions. Moreover, a numerical case is illustrated for presenting rough set approach (RSA) to quantize the influence degree of these factors on electronic payment system adoption. The results derived from the case reveal that only 20 percent of buyers take electronic payment system as their first choice, security and trust have more significant impact on users' attitude than other influential factors. Finally, the paper concludes with the limitations of the study and several suggestion for future research.


Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, and has become a pandemic since March 2020. Morbidity and mortality vary between populations. For instance, African Americans in the U.S. are disproportionately affected by COVID-19 and show higher mortality compared to the other race and ethnic groups. However, it is not clarified whether the difference in genetic susceptibility to SARS-CoV-2 infection may exist or not. We surveyed publicly available database of genomic variants across populations (Latino, European, East Asian, South Asian etc. including Japanese) to find allelic variation across populations in the genes involved in viral entry to the host cells such as ACE2, TMPRSS2and CTSB/L, and sensing molecules of viral genomic RNAs such as TLR3/7/8. Overall, amino acid residues that are critical for host-viral interaction and sensing of viral genome are highly conserved across populations. Genetic determinant for the binding affinity between SARS-CoV-2 and ACE2 does not show significant difference between populations. Therefore, SARS-CoV-2 uses highly conserved molecules as its virion interaction, whereas its immune response appears to be genetically biased in individuals to some extent.


In a documentary called Attrazione D'amore, the cinematographer Frank Scheffer provides footage from a lunch concert at Amsterdam's Royal Concertgebouw. When the orchestra starts to play Mozart's Piano Concerto No. 20 in D minor, it becomes apparent that the renowned pianist Maria Joao Pires had made a mistake. As the director of the concert, Riccardo Chailly, recounts in the film: "She was shocked because she was expecting us to play another concerto. So when I started the first bar of the D...


The effects of ultrasound treatment on the quality of Yizhou chaenomeles were studied. Yizhou chaenomeles were treated respectively with ultrasonic wave(power of 200 W, frequency of 50 kHz) for 3, 5 and 10 min. The changes of the factors such as soluble solids, VC, titratable acids, hardness, weight loss and rotting rate were determined under the normal temperature condition. The results showed that the 5 min treatment can retain the content of VC, titratable acids and hardness, inhibit the increase of soluble solids, and reduce weight loss and rotting rate.


The polymerization of norbornene in the presence of different bis(salicylaldiminate)copper(II) complexes and methylalumoxane has been investigated. In all cases a high molecular weight vinyl-type polymer was obtained. The presence of electron-withdrawing nitro groups on the chelate ligand markedly increased the activity of the catalyst. The influence on the catalytic performances and polymer characteristics as a function of reaction parameters, such as temperature, duration, and content of free trimethyl aluminum in the commercial MAO, was studied.


Abstract The predominant serovars of Salmonella associated with environmental contact surfaces and utensils used in processing and selling roasted chicken in Dutse town of Jigawa State was determined. The aerobic plate count of the one hundred (100) cotton swab samples collected from studied surfaces was determined. Cultural Identification of the isolates was done on Salmonella - Shigella agar (SSA) followed by microscopy. Biochemical confirmatory tests and serological tests using polyvalent and monovalent sera were conducted. Antibiotic sensitivity pattern of the isolates was determined by the Kirby Bauer disc diffusion method. Thirteen (13) samples yielded growth of Salmonella serotypes, giving a prevalence rate of 13.0%. S. enteritidis serotype was the most identified (46.0%) while S. Virchow (8.0%) was the least. The highest bacterial load was observed on the hands of vendors, with an aerobic plate count of 4.4 ×10 4 CFU/g while the least was observed on cutting board utensil (2.5×10 4 CFU/g). Rate of contamination was found to be most significant on hand swab samples (38.0%) and least on knife swab samples (8.0%). Isolates were most susceptible to Chloramphenicol and Gentamicin but highly resistant to Septrin, Peflacin, and Tarivid. The hands, contact surfaces and utensils used in the processing of roasted chicken must be adequately sanitized with appropriate sanitizers so as to prevent the dissemination of pathogens such as Salmonella to consumers.

A method comprises determining a reference ratio based on a first division ratio of a first phase-locked loop (PLL) and a second division ratio of a second PLL, and converting a first discrete sequence to a second discrete sequence based on a sequence of multiples of the reference ratio. The first and second PLLs operate under a locked condition and share a common reference oscillator. An apparatus includes comprises a clock generator including first and second phase-locked loops (PLLs) and configured to generate first and second clock signals, respectively, and a sample-rate converter configured to convert a first discrete sequence to a second discrete sequence based on a sequence of multiples of a reference ratio. The reference ratio is determined based on a first division ratio of the first PPL and a second division ratio of the second PLL.


Potamopyrgus antipodarum is one of the most widespread invasive species worldwide and its expansion is ongoing. Although the snail has already been documented as surviving the digestive tract of various fish, there is insufficient data on potential riverine fish predators of P. antipodarum and of the ability of the snail to survive digestion by these fish. Lotic ecosystems are unfavourable for the upstream spread of this species by active movement and thus it is suspected that benthivorous riverine fish facilitate such upstream dispersion. In general, the results of this study indicated that P. antipodarum is not a preferable food object for the studied riverine fish. The study did indicate, however, that the invasive snail is capable of surviving the digestive tract of all the studied fish. As accidental consumption of abundant P. antipodarum with other food objects has already been documented, this study suggests that riverine fish can act as potential secondary dispersion vectors, facilitating the upstream dispersion of the snail.


The objective of this study was to investigate the effect of perceived adherence to psychological contract on citizenship performance and mediating role of organizational loyalty among an industrial company. In this study, 226 people through conveniance sampling were selected. Tools included Rousseau Adherence to Psychological Contracts (1995), Lee and Allen Organizational Citizenship Behavior (2002) and Kumar and Shekhar Organizational Loyalty Questionnaire (2012). Data was analyzed with SPSS software (version 18) using descriptive-analytical statistics such as coefficient and Structural Equation. Results showed that There was a significant Direct effect on transactional psychological contract and organizational loyalty (p<0.01,0.001), and on relational psychological contract and organizational loyalty (p<0.05,0.06), and also on significant Direct effect organizational loyalty and the performance of the citizens (p<0.01, 0.001).The results of the structural equation analysis showed that transactional psychological contract and organizational loyalty first, and then through organizational loyalty effected the performance of citizens and communicational psychological contract, also directly effected the performance of citizens. Hence, it can be concluded adherence to psychological contracts are important anticipations for the performance of corporation citizenship. on the other hand, Commitment to the psychological contract increases organizational loyalty and organizational loyalty provides all the conditions for performance of the citizens.

Objective
To investigate the characteristics of the 24 h ambulatory blood pressure in type 2 diabetic patients with chronic kidney disease(CKD).

Methods
A total of 510 type 2 diabetic patients hospitalized from September 2009 to December 2013 were enrolled in this study. The patients were divided into six groups according to K/DOQI staging of CKD: non-CKD(94 cases), stage 1 CKD(134 cases), stage 2 CKD(122 cases), stage 3 CKD(80 cases), stage 4 CKD(36 cases) and stage 5 CKD(44 cases). The incidence of hypertension in those groups were calculated. The data were compared with one-way analysis of variance among groups. Multiple stepwise regression analysis was applied to evaluate the effect of every indicators on estimated glomerular filtration rate.

Results
The incidence of hypertension increased significantly in type 2 diabetic patients with CKD, with a incidence rate of 95.4% in stage 5 patients(χ2=54.533, P 0.05). The predictors of atherosclerosis, pulse pressure and ambulatory arterial stiffness index, increased significantly along with the progression of CKD(F=32.829, 10.134, P<0.05). The decrease of nighttime systolic and diastolic blood pressure declined along with CKD progression (F=17.827, 10.519,P<0.05). Multiple stepwise regression analysis indicated that estimated glomerular filtration rate was negatively correlated with systolic blood pressure and pulse pressure(β=-0.201,-0.237, both P<0.01),and positively correlated with body mass index, percentage of night reduction rate of diastolic pressure and smoothness index of systolic blood pressure (β=0.134,0.151,0.145, all P<0.05).

Conclusion
The incidence of hypertension increased significantly in type 2 diabetic patients with CKD, with increasing of systolic blood pressure and pulse pressure and obvious abnormal circadian rhythm. So monitoring on blood pressure rhythm of these patients should be strengthened.

Preliminary attempts were made to isolate hexokinase
from human erythrocytes and placenta. The final purifications
were made from heart, which contained more enzyme
than other tissues. From 1.15 kg of heart, 25 mg of hexokinase
was obtained of specific activity 58 units/rng.
This represents a 1,700-fold purification and a yield of
I+7% over six steps. A critical development in isolating
" this enzyme was the use of affinity chromatography, using
glucosamine linked to Sepharose".
The material contained"a single protein component
according to electrophoresis on starch gel, cellulose
acetate and polyacrylamide gel. It gave a single peak on
gel filtration, and on sedimentation in the ultracentrifuge.
However, a heterogeneity in size was indicated by
electrophoresis on SDS-polyacrylamide gels which gave two
bands of approximately equal intensity. The apparent
molecular weights of these components were 109,000 and
124,000. The small difference in size has not resolved
by the other techniques used.
Gel filtration on Sephadex G-200 suggested a molecular
weight-of 106,000, as did the combination of the 'sedimentation
coefficient of 5.5 S and diffusion coefficient
of 47 μm2/s.
