Moreover, the students can know which part they should improvee. Task-based learning also creates a learning process which is more focused. It is said so because in teaching-learning process followed some steps which makes the learning process is more focused.
Those finding indicate that the use of task-based learning method is effective in improving the students' mastery of simple past tense in recount text as well as their motivation.


Radio frequency interference (RFI) is a common source of interference in high-frequency (HF) surface wave (HFSW) radars owing to cochannel interferences (CCIs) in the user-congested HF band. The existence of RFI degrades the detection performance of HFSW radars because its amplitude is high enough to mask the sea and target echoes. Two types of common RFI can be observed in observation data. One of them presents sloping stripes (RFISS) in range-Doppler spectrum (RDS) and another one, which is more common, leads to vertical stripe paralleling to range axis in RDS. In this paper, a unified model in order to represent the characteristic of the two types of RFI for the frequency-modulated continuous wave (FMCW) radar system is presented. On the basis of analysis of this generalized model, a new RFI suppression algorithm based on inverse temporal windowing and complex empirical mode decomposition (CEMD) is proposed. Test results show that the proposed method can effectively suppress dense RFI without losing sea echoes in practical condition.


The main objective of this work is to split the video into multiple parts and send each part over a different path based on the amount of traffic in each path. Traditionally UDP protocols were being used for the transmission since they do not have acknowledgements. UDP is used since real time traffic uses RTP protocol for multimedia transmission. TCP is a connection oriented protocol not suited for delay sensitive transmissions .In this paper, the TCP protocol has been modified with an efficient congestion control algorithm. In this algorithm, the congestion window limit is determined based on the four parameters like short term throughput, packet out of order arrival, inter-arrival time and packet loss ratio. The performance study has been done with these UDP and Modified TCP protocols by multipath multicasting video over MANETS.


the V^/Q inequalities. Continuous positive airway pressure delivered through a face mask increases end-expiratory lung volume. Gas delivery to well-perfused, but atelectatic or poorly ventilated lung areas, is improved, and arterial oxygen saturation increases. However, venous return to the heart may be impaired, and cardiac output may fall, as a result of the increase in intrathoracic pressure. Endotracheal intubation and mechanical ventilation is indicated to protect the airway when consciousness is decreased or when severe respiratory distress or acute respiratory acidosis is present. Controlled studies that specifically compare different ventilatory techniques in ventilatory failure inhalation injury are lacking. Ventilator settings are chosen so that SaO2 exceeds 90% and so that pH is within an acceptable range. Positive end-expiratory pressure is used to improve oxygenation and reduce the need for fractional concentrations of inspired oxygen (F1O2) of more than 0.6. If there is significant airway obstruction, inspiratory time may have to be shortened to allow for complete expiration. It is important to recognize that mechanical ventilation is a supportive measure, and not curative in itself. Moreover, mechanical ventilation is associated with many side effects. It can be shown experimentally that ventilation with high-tidal volumes or high-peak inspiratory pressure induces lung injury. It is essential to minimize the risks of such complications during mechanical ventilation. Close monitoring of hemodynamic and pulmonary function identifies adverse effects, such as excessive alveolar pressure, dynamic hyperinflation, and compromised cardiac function, and permits prompt action to be taken against these complications.


. A compartmental mathematical model of the transmission dynamics of the monkeypox virus (MPXV) was developed and analyzed. The model incorporates proper surveillance and contact tracing as effective controls. The equilibrium states of the model were obtained and analyzed both locally and globally. The effective reproduction number, R m was obtained and the sensitivity of the model parameters were studied using R m as the threshold of transmission. When the infection becomes endemic, R m (cid:117) 1 , the model exhibits a backward bifurcation but R m < 1 which means that the interventions tend to MPXV containment. Numerical simulations to bespeak our findings and discussions are provided. Our result shows that surveillance and contact tracing are effective for the containment of MPXV in the absence of a perfect vaccine.


In this paper, we report on the investigation on filament interaction and pattern evolution in glow DBD regime by using a fluid model. The aim is to find the leading mechanism controlling the filamentary dynamic behaviors. Space-charge and voltage (or surface-charge) fluctuations are introduced into the discharge space to trigger initial non-uniformity of glow DBDs. Filamentary dynamic behaviors of generation and annihilation, merging and splitting, and attraction and repulsion are observed in interaction and evolution process under both kinds of fluctuations. It is found that, localized lateral electric field and its induced electron-focusing effect (EFE) should be the controlling mechanism, which is significantly influenced by discharge intensity, filament diameter and distance. If neighboring discharge channels connect or partially overlap with each other, they will attract and merge under the combined effect of lateral bi-diffusion and EFE. The fluid model and a dynamic model based on voltage transfer character are compared from basic physics and reach good unification.


Massive stars are rare but crucial to understand the cycle of matter in the interstellar medium of the Milky Way, as they are the most important cosmic engines which drive the evolution of galaxies through the history of the Universe. Significantly influenced by their rotation, bulk motion or by the presence of a companion, their strong winds and ionising ultra-violet photons that heat gas, shape their surroundings while chemically augmenting their ambient medium. Throughout their live, massive stars evolve from a hot main-sequence star to a cold inflated red supergiant star, via the eruptively mass-losing Luminous Blue Variable and/or winddominated Wolf-Rayet phases. These rapid changes provoke strong variations in the their close surroundings and this leads to a highly structured circumstellar medium. The final explosion of massive stars as supernova releases chemically-enriced ejecta and drives shocks inside their own organised circumstellar nebulae. Such events give birth to ∼ 100 pc-large and efficient cosmic-ray-producer supernova remnants such as in Fig. 1. Although most massive stars form in group, a fraction of them, classified as runaway, are ejected out Figure 1: X-Ray view of remnant N132D [1].


Multidrug resistance has been increasing world wide amongst most microrganisms, and adding to increased rate of both hospital and community acquired infections. Of all resistance mechanisms the alarming spread of carbapenemase producers is most worrisome and needs to be tackled head on. The present study was undertaken with the objective of determining the prevalence of carbapenemase producers and its significance in selecting the appropiate antibiotic for clinical use.The study was undertaken by the department of Microbiology and Immunology of SGRRIM&HS, Dehradun over a period of six months. A total of 1918 varied clinical specimens were subjected to Bacterial identification and antibiotic sensitivity determination. Further carbapenemase production was detected phenotypically using modified carbapenemase inactivation method (mCIM) for randomly selected 152 carbapenem resistant gram negative isolates. Total of 58.55% isolates tested mCIM test positive of which the highest percentage (71.4%) were Pseudomonas spp, while 17.2% isolates were not found to be carbapenemase producers i.e mCIM negative. These results substantiate the importance of differentiating the carbapenemase producers from non producers to aid in rational use of antibiotics.


Preliminary tracking system design and analysis is typically done using simulated data in which the target truth is known and many techniques have been developed for evaluating performance under these conditions. However, there is a notable lack of any consistent approach for evaluating tracker performance for real data in which there may be an unknown number of targets of opportunity whose trajectories are not known. In addition, the background clutter/false alarm environment may be unknown so that an important analysis task is to determine the most accurate background models. This paper proposes a set of criteria for evaluating the tracks that are formed using real data collected in the field in the presence of an unknown number of targets of opportunity. These criteria include duration, update history, and measures of kinematic and data association consistency. A scoring method is developed and the use of these criteria for system design is discussed.

A method for playing data using networks is provided to guarantee the continuity of the broadcast information by using mobile communication network where a broadcasting signal communication is not available. A broadcast signal is received through the first communications network(S103). A first broadcast information is generated by demodulating and decoding the first broadcast signal(S105). If the broadcast signal cannot be received, the second broadcast information corresponding to the first broadcast information is received through the second communications network(S109,S119). The received second broadcast information is reproduced(S125).


There are some problems in China's environmental enforcement coordination mechanism, such as lack of high standard legal coordination lead unit in environmental enforcement and lack of information communication mechanism in running the coordination mechanism. Improving environmental enforcement coordination mechanism is the goal and direction of China's administrative reform, we can learn from the experience of the United States, Japan, the Philippines and other countries. In order to establish a specialized environmental law enforcement coordination agency, we should try to improve relevant laws and regulations, to establish "cooperation and coordination"model, to stablish "three sides"monitoring system and to improve information sharing mechanisms and public participation mechanisms.


This synthesis will be of interest to finance officers, administrators, legislators, and others interested in the actions that states take to stem evasion of highway fuel taxes. Information is presented on the types of schemes that are being used to evade paying fuel taxes and on practices that have been successful in eliminating those schemes and increasing fuel tax revenues. With shortages of funds to meet current and future highway needs, it is important for states to stem evasion of fuel taxes. This report of the Transportation Research Board describes some of the schemes that have been devised to evade paying fuel taxes and a number of successful practices that states have used to foil those schemes.


A PARABOL1ZED Navier-Stokes (PNS) prediction method developed to treat laminar flow over a sharp cone at incidence to a supersonic or hypersonic freestream has been extended to consider flow over a spherically blunted cone at angles of attack up to 38 deg. The basic method treats the flowfield between the body and the bow shock by one set of equations that are valid in both the viscous and inviscid regions. A description is given of the computational methods used, and results are compared with inviscid flowfield calculations and experimental data. The shock shape predictions were found to be in good agreement with most of the inviscid results as well as in reasonable agreement with some low Reynolds number heat transfer experimental data.


In pairs bridge competitions, the same cards are played at a number of tables. At each table, two pairs meet in a match. The pairs then circulate according to some playing scheme, a design, to play other cards against other opponents. In a match, one pair plays what is called the North-South (NS) cards and the other the East-West (EW) cards. If one considers tables as rows and NS and EW as two columns, we realize that nested row-column designs can be used. In this paper a statistical model is formulated and good nested row-column designs with good row component designs are sought. Another block component design with rounds as blocks is often introduced, which means that we require a kind of double resolvability. A generalization of Howell designs can then be useful.


The major outputs of the Expert Group Meeting on Population Distribution, Migration, and Development, held in Tunisia during March 1983, were the formulation of well rounded principles and objectives in the areas of urbanization, internal and international migration, and population distribution which have policy relevance for development to help the review and appraisal of the World Population Plan of Action; and the compilation of recommendations in these areas. The substantive agenda items discussed at the meeting were as follows: internal and international migration; migration and rural development; urbanization, migration, and the growth of large cities in developing countries; the turnaround of urbanization in developed countries; and population distribution policies. The following are among the recommendations made: population distribution policies should be justified in terms of their positive benefits rather than as a means of correcting alleged adverse trends in the distribution of population; population distribution goals should be adopted to help achieve predetermined broader societal goals such as raising per capita incomes, increasing efficiency, or improving the distribution of income by taking into account those left behind or those affected by mass immigration; population distribution policies should be tailored to the specific needs of a country's political, economic, and institutional structure; governments should make available information on employment, social, and economic conditions in places of potential destination for individuals who may be considering migration; where policies to encourage migration are formulated, their implementation should be carried out in close cooperation with migrants, taking into account their needs as well as those of persons affected by migration; governments are urged to provide the resources to collect data, particularly with respect to the variety of migration streams; in formulating policies on international migration receiving countries should take into account not only their own economic and social needs and the well being of the migrants concerned but the needs of the sending countries and the longterm implications of migration for both migrants and the communities concerned; and countries should ensure that migrants have adequate access to health and social services.


The difference of skin red index and fruit water loss are compared at the different storage temperature of Lizao fruit, which are two important apparent indicatots of judging Lizao fruit quality. The storage effect in the plastic bag and fresh keeping chemicals with TD, TP and TDGNC at the room temperature, 10℃ and 0℃ were investigated, the results showed that it will benefit to keep fruit firm and higher soluble solid and to reduce fruit rot under the lower temperature. Mildew, boltch and other bacteria diseases are inhibited significantly at fresh keeping chemicals TD, TP and TDGN, commercial fruit tate increases 10 percent compared with control.


Myasthenia Gravis (MG) is a rare disease of neuromuscular junction which typically presents with fatigable weakness of cranial and limb muscles. But patient may present with vague symptoms which may mislead physicians to an incorrect diagnosis. We are reporting a 45 year old cobbler presented with the complaints of lack of energy, aching pain in shoulder, back, upper arm and difficulty in swallowing of both solid and liquid food without any diurnal variation for two and half years. He was ultimately diagnosed as a case of MG and thymectomy revealed thymoma. DOI: http://dx.doi.org/10.3329/jom.v13i1.10087 JOM 2012; 13(1): 109-114


The keto−enol tautomerism of benzoylacetone (1-phenyl-1,3-butadione) in aqueous acidic solution at 25 °C was investigated by studying the influence of anionic, cationic, and nonionic surfactants in the UV−vis spectra of benzoylacetone. The percentage of the enol tautomer was found to increase abruptly at surfactant concentration above the critical micelle concentration (cmc). A model is proposed to quantitatively interpret the experimental results, which allows for the determination of the enolization constant in water, KE, and in micellar, pseudophases; the binding constant of the enol tautomer to micelles, Ks; and the extinction coefficients of the ketonic and enolic forms, e, of benzoylacetone. The formation of the enolate in the absence and presence of micelles in basic media was also studied. The acidity constants of the enolic, and ketonic, forms of benzoylacetone have been determined.


In March 2020, when the World Health Organization declared COVID-19 a pandemic, more than 90% of the world's student population went through an unprecedented and sudden transition to distance learning. Although this was a challenging time for instructors across all disciplines, entrepreneurship educators faced the unique dilemma of preserving the experiential nature of entrepreneurship education in the online environment. We look at how entrepreneurship educators addressed experiential learning through online education during the pandemic and some of the solutions adopted given the experiential, hands-on nature of entrepreneurship education. We review the first wave of literature on the topic, and we offer the results of a recent survey of entrepreneurship educators who are members of the United States Association for Small Business and Entrepreneurship (USASBE). In doing this, we have added to a growing literature on the shift of entrepreneurial education to an online setting.


To compare the prevalence of Eimeria macusaniensis among midwestern llamas (Lama glama), alpacas (Lama pacos), and guanacos (Lama guanicoe), feces were obtained from Lama spp. in 10 states between October 1989 and February 1996. Feces were examined by centrifugal flotation in sugar solution (specific gravity = 1.28-1.30), and oocysts were quantified by a a modified McMaster method. Data were compared by host species arid age classifications. Typical oocysts occurred in samples from 28% of 76 herds and 10.4% of 443 animals including 12% of 301 llamas, 7% of 115 alpacas, and 7.4% of 27 gua nacos. Prevalence was significantly greater (P = 0.009) in animals <1 yr of age in comparison to older animals for llamas (22.L vs. 8,5%) and for all Lama spp. combined (17.1 VS. 8.4%). Fecal oocyst abundance was significantly greater (P = 0.001) in llamas < 1 yr of age in comparison to older llamas (30 vs. 16 oocysts per g of feces). Fecal oocyst intensities did not differ significantly. Prevalence in both age groups of midwestern llamas was greater than previously reported for llamas in the western United States. Prevalence in midwestern alpacas < 1 yr of age was lower than reported for alpacas of similar age in South America, but oocyst intensities were similar. These results indicate that infection with E. macusaniensis is more common its Lama spp. in North America than previously recognized.


A careful reader discovered, and reported to the editor of this journal, that the same figure was published to illustrate different experiments in two separate articles from this laboratory. Indeed, Figure 3 from "Olfactory Cues Accelerate Reentrainment following Phase Shifts and Entrain Free-Running Rhythms in Female Octodon degus (Rodentia)" (Governale MM and Lee TM [2001] J Biol Rhythms 16:489-501) is the same as an earlier example of a degu phase-shifting experiment found in Figure 2 of "Social Cues Accelerate Reentrainment of Circadian Rhythms in Diurnal Female Octodon degus (RodentiaOctodontidae)" (Goel N and Lee TM [1995] Chronobiol Int 12:311-323). I am grateful for the reader's attention and apologize for the error. It is not entirely clear how the error occurred. However, I have multiple figures in my database with very similar names. Apparently, I pulled the wrong figure when I was preparing the final version of the paper for submission. Because the data demonstrated the same effect of olfactory cues improving recovery from jetlag, and because the rates of recovery were nearly identical in the two studies (although the olfactory cues were delivered quite differently), I did not notice the error. M. Governale has no fault in this, as I prepared the final figures to be sent after she had graduated and left my laboratory. The data for the remaining figures and tables in the Governale and Lee article have been rechecked, and all are correct and represent data not published elsewhere. Here is the figure that should have been Figure 3 in the article in Journal of Biological Rhythms, showing an example of hastened recovery after a phase shift (advances in this example) when the degu, housed in an environmental chamber, was exposed to a continuous airflow containing the odors of conspecific females housed in a separate chamber.


Background: Granulomatosis with polyangiitis (GPA) is autoimmune-mediated, necrotizing granulomatous vasculitis, primarily involving the upper and lower respiratory tract and kidneys. Pulmonary parenchymal necrosis, vasculitis, and granulomatous inflammation are the main pathological features. Pulmonary imaging visualizes various manifestations, like lung consolidation, ground-glass shadow, speckle shadow, nodules and mass shadows, cavitation, pulmonary interstitial change, pleural effusion, and multiple mediastinal lymph nodes enlargements, and stenosis or occlusion of a lobe or bronchus segment. Case presentation: We report a 53-year-old patient diagnosed with Granulomatous polyangiitis with multiple pulmonary nodules and masses, by ultrasound-guided lung mass puncture biopsy. After treatment with methylprednisolone, Mycophenolate Mofetil, compound sulfamethoxazole and cyclophosphamide, the patient's condition improved and the pulmonary lesions were better than before.Conclusions: In addition to specific infections and tumors, immunological diseases, especially granulomatous polyangiitis, should be considered when treating patients in a clinical setting with multiple pulmonary nodules and weights. Through close multidisciplinary cooperation and communication, the disease will be hopefully received timely diagnosis and early treatment, relieving pain for more patients.


This article presents a case study of the parking program in Corpus Christi, Texas, which has been undergoing a significant overhaul due to the implementation of an ambassador-style enforcement program. Among the results of this new approach to parking management are the allotment of $300,000 from the city council to upgrade meters, increased revenues, increased quality of life as a result of safer and cleaner neighborhood streets, and an increased respect for the parking control division of the local police department.


Marion saw it; she was there. And she knew how beautiful it can be, the joy of working with a single cell, watching its responses to stimuli, and determining which reactions were most important and pertinent to human physiology and pathology. The thrill of discovery was all hers, and a brief moment of pain on a dark street will never take them away. Marion was a very real person and I will miss her. The platelet Marion saw has been the subject of great interest to me as well. Recent work in our laboratory has focused on the cytoskeleton of the platelet and its reorganization in response to stimulation. The scanning microscope image that Marion described so well will serve as a background for dissection of the platelet cytoskeleton in this presentation given in her memory.


In recent years, the interest of researchrs in using fly-ash as a raw material for the geo-polymer synthesis is increasing. Kuzbass region (in Russia) has a large amount of ash wastes generated, which defined the relevace of the study performed in this paper. Results of investigating load-bearing capacity of structural insulating material produced by geo-polymerization of fly-ash of Kemerovo hydro-electric power plant with the addition of complex activator are described in the paper. Hydrogen peroxide solution was used as the foaming agent. The activation time, the temperature of isothermal holding and hardening in normal conditions for all samples were constant. The compressive strength and the mean density of geo-polymer foamed concrete were determined. The influence of the material composition on its properties was revealed. It is found that of the geo-polymer foamed concrete with the optimum composition has hardness of 1,1-3,5 MPa at the density of 400 to 900 kg/m3. Thus, the production of the fly-ash...

Geographic variations in two social behavioural characters, waving display and barricade building, and genetic population structure were examined in the tidal‐flat‐inhabiting dotillid crab Ilyoplax pusilla (de Haan, 1835), in six localities between the northern and southern limits of its distributional range (four localities from the Japanese mainland and two southern localities from the Ryukyu Islands). Although waving motion followed the same lateral–circular pattern in all of the local populations, cheliped‐extension at the wave peak was most prominent in the Yakugachi River population (near the distribution's southern limit in the Rykukyu Islands), followed by Haneji Inlet (the southern limit in the Ryukyu Islands) and four localities on the Japanese mainland in that order. The frequency of barricade building showed a similar trend, namely lowest in Yakugachi River, followed by Haneji Inlet and the four mainland localities. Genetic relationships among the six local populations revealed that the two southernmost populations (Yakugachi River and Haneji Inlet), particularly the former, differed significantly from the mainland populations. The similar geographic trend between social behaviour and genetic structure suggests a relationship at some level between the two.


Bleeding during surgery is a serious clinical problem that can be very disconcerting to the patient and could have serious consequences. During the course of nearly all types of surgery, blood vessels will be disrupted, causing some bleeding. The dentist should be familiar with the general techniques of hemorrhage control for different types of bleeding episodes—small vessels, large vessels, oozing, drug-induced, or when an underlying coagulation defect is present. Bleeding complications can occur in healthy as well as systemically compromised patients. This article reviews the types of haemorrhage and various measures for their management. It also discusses the various haemostatic agents used in the management of bleeding episodes in oral surgery. Keywords-Haemostatic agents, Haemorrhage, Dental surgery, Haemostasis INTRODUCTION Haemorrhage means the escape of blood from a blood vessel. Haemorrhage generally indicates extravasation of blood due to vessel rupture. Blood carries oxygen and nutrients to the tissues and is vital for body functions. Loss of blood due to any reason beyond a certain point is potentially life threatening and may lead to loss of life. Types of haemorrhage Depending on the type of blood vessel involved, haemorrhage can be arterial, venous or capillary. Arterial Haemorrhage: In arterial haemorrhage, there is bleeding from a ruptured artery. Arterial bleeding is pulsatile, brisk and bright red in colour. Venous Haemorrhage: Loss of blood from a vein is known as venous haemorrhage. Bleeding from veins is dark in colour and blood flows in an even stream. Due to lack of valves in veins of the facial region and extensive communication, there is relatively more flow from veins as compared to other parts of body. Capillary Haemorrhage: Oozing from the capillaries is known as capillary haemorrhage. In capillary haemorrhage blood oozes from the area and no bleeding point can be made out.(1) Depending on the duration of haemorrhage it can be classified as Primary, Reactionary/Intermediate Bleeding and Secondary Bleeding: 1. Primary bleeding: occurs at the time of injury. Haemostatic mechanisms in the body attempt to stop the bleeding by formation of clot. 2. Secondary bleeding: If the primary bleeding has stopped and wound starts to bleed again after 24 hours to several days, it is known as secondary bleeding. It may be due to: (a) dislodgement of clot (b) secondary trauma to the wound, (c) infection( the most common reason for secondary bleeding) (d) elevation of patient's blood pressure enough to overcome pressure external to blood vessels. 3. Intermediate bleeding/ Reactionary bleeding: Bleeding occurring within eight to 24hours after stoppage of primary bleeding is labelled as intermediate bleeding. Loose foreign body in the wound like calculus, broken bone piece, and pre-existing extensive granulation tissues in the extraction socket are the most common causes for the intermediate bleeding.(2) Laboratory Tests for Screening Majority of defects of haemostasis can be screened by four basic tests.


Nine genera of minute nonmycelial fungi characterized by a thallus of one to 15 cells in linear arrangement, a usually darkened holdfast, and often endospores cut off in succession are known from arthropod hosts. The taxonomic relationship of these minute fungi, including Thaxteriola, has been the subject of speculation, and morphological comparisons have been made to the Laboulbeniales. One genus has been synonymized with Fyxidiophora in the Hypocreales. The discovery of a new species of Fyxidiophora with a Thaxteriola anamorph on mites associated with the southern pine beetle gives new evidence of relationships and points out the importance of a mycological curiosity as a dispersal stage. This anamorph is nonmycelial, highly specialized, and unlike any known for an ascomycete. Spegazzini (1918) described the genus Thax-teriola and its species, T. infwcata Speg. and T. subhyalina Speg., from beetles in Argentina. Several years earlier Thaxter (1914) had illustrated a similar fungus of a type he found on a variety of insects and occasionally on the laboulbeni-alean fungi on the insects; no formal description was given because he knew nothing of its development. Thaxter (1920) later accepted Spegaz-zini's genus and. described a third species, T. ni-gromarginata, on a staphylinid from Java. He cautioned that many species probably exist and that eventually "posterity will have become burdened with a horde of these uninteresting little plants." However, only one additional species, T. moseri Majewski et Wibniewski (1978a), has been formally described from mites in Poland. Other genera of morphologically similar fungi are known from insects, mites, and a centipede. (TABLE I). Common features include morphological simplicity with thalli having one' to four or fifteen cells in linear arrangement, a usually darkened holdfast, and endospores cut off in succession (except in Laboulbeniopsis and Cor-eomycetopsis, see under Discussion below). Haustoria have not been reported for any of the species, and the mode of nutrition of the fungi in the aerial environment is unknown. While these forms are not encountered by most mycologists they have been of interest from a phylogenetic point of view because they are so different from other h g i. The resemblance of these fungi to the male thalli of some dioecious laboulbenialean species has been noted several times. Thaxter (1914, 1920) pointed out that the similarity of Ampho-romorpha, Thaxteriola, and Endosporella to the male thallus of species of Dimeromyces and Am-phoromyces was probably only superficial and did not indicate a relationship with the …


Using the cosmic composition of elements as given by Aller and utilized by Bell and Kingston, and the total photon interaction cross sections per atom of the elements as computed by Hubbell and collaborators, the x‐ray interaction cross sections are computed for three cosmic mixtures over the range 1 keV (12.4 A) to 1.5 MeV (0.008 A). The results are compared with a formula given by Heiles. Approximate agreement exists between 10 to 20 keV.


This study investigates the physical properties of pure palm fatty acid distillate (PFAD) as a new, clean and renewable source of lubricant and hydraulic oil. This study is done using a four-ball tribotester. The experiments are conducted at five different temperatures of 55, 75, 95, 105 and 125 °C. The rotational speed was fixed at 1200 rpm, normal load was 40 kg and duration was 1 hour. For evaluating the results, all experiments again were conducted using commercial engine mineral and hydraulic mineral oil and at the end all results were compared together. The results show that PFAD has higher anti friction and anti-wear ability.

The structured problem solving is important methodology in quality improvement. This article discuss the problem solving should be approached in a structured manner using team. Firstly, discuss the concept of problem and structured problem solving. Secondly, descript the base of structured problem solving is the Deming circle: PDCA. And introduce the Bank's 6 steps process of the problem solving. Thirdly, discuss the important of a structured manner using team in problem solving. Fourthly, discuss the argument about the problem solving. Finally, appraise the view of structured problem solving in critical way. And give an example of Toyota how to setup a practical problem solving process and integrate the quality management systems. Through the study, we can learn that when the companies try to meet or exceed customers' needs and expectations, they often need to face different kinds of problems. The structured problem solving is important methodology to fix the problem and improve the quality. And we also need to think about to integrate the problem solving process in the framework of TQM, and understand important of the organization structure in problem solving. And the zero defects are also a good concept and practical way to reduce the quality problem in an organization.

Two adolescent case reports of Class II Div I malocclusion are presented, the first of a 16years old girl with dentoalveolar protrusion, mild crowding in the upper anterior segment, increased overjet and the second of a 13years 1 Omonths old girl with rotated labially placed maxillary canines with mild crowding in the upper anterior segment. Non-extraction treatment w as undertaken in both the cases with distalization of maxillary molars with Distal Jet appli ance to correct the cl ass II relationship. Distalization often comes with adverse effects of uncontro lled tipping, anchorage loss and third molar impaction . The focus will be on Diagnosti c criteri a for pati ent se lection and countering strategies to combat the side effects. Clinical review on the Distal Jet appliance has also been presented.


We studied an optical method of diffuse wave interferometry based on a random moire principle, permitting, in real time, the measurement of very small displacements or vibrations under experimental conditions which are unusual by reason of their weakly constrain-ing character. In fact, - the field of application is that of objects with unpolished surfaces, observed perpendicularly to this surface, for displacement vectors situated in the plane of this surface; - the setup demands only ordinary precision ; it is composed of a lighting system with two coherent (laser) waves and a low-resolution imagery system followed by a detector ; - the mode of operation consists in the detection of variations of lighting in a laser image granularity spot ; under certain conditions, these variations are propor-tional to the displacement of the point corresponding to the object ; - the performances : the sensitivity is interferometric ; the theoretical limit is on the order of 0.1Å√Hz standard experimental conditions. Values close to this limit have been attained experimentally. The precision of the measurements is on the order of 1%.


Clinical, histological and ultrastructural features of three small cell carcinomas arising in the parotid gland are presented. The light microscopic appearance of two of the neoplasms suggested neuroendocrine cell derivation, confirmed by electron microscopy in both instances. The fine structure of the third neoplasm suggested intercalated duct cell differentiation. The possibility that both types of neoplasm may arise from the same primitive precursor cell is considered. The findings from this study confirm the occurrence of two different types of small cell carcinoma of salivary gland origin. A distinction between duct cell and neuroendocrine subtypes may be impossible by conventional light microscopic evaluation. Cancer 52:2115‐2121, 1983.


Since few years, the single-crystal fiber (SCF) technology has demonstrated very interesting features, combining the advantages of bulk crystals and glass fibers. Thanks to a very efficient thermal management and a high overlap between the guided pump and the unguided signal, SCF technology is well suited with the requirement of Master Oscillator Power Amplifier (MOPA) dedicated to high average power pulsed laser [1]. Recently, 30 W average power at 380 fs pulse duration has been demonstrated using a single SCF amplification stage [2]. In the frame of the European project "Ultrafast RAZipol", we present in this paper a MOPA setup using three successive SCF amplification stages to reach an average power up to 100 W at sub-picosecond pulse duration and 20 MHz repetition rate.


There have been several algorithms in the literature that use Clabke's generalized gradients to find descent directions for minimizing Lipschitz functions, The result used to find these directions states that if zero is not a generalized gradient to a Lipschitz function f at xthen there is an y that is a direction of descent for f at all points in a neighborhood of x. In this paper it is shown that, even though there may not be descent directions, there are paths of descent if f is lower semicontinuous. This is done using a characterization of Clabke'S tangent cone in terms of Lipschitz paths.


High resolution SEM should be, in theory, the most useful instrument to investigate the extracellular matrix of connective tissues, in that it should provide information on the molecular arrangement at 3D level. In SEM, however, collagen fibrils are hardly distinguishable from the other components. In fact while in TEM the collagen fibril is easily detectable for its periodicity, in SEM the latter is rarely seen (1). This may be due to the conductive coating that usually masks the collagen banding.In this work we tried to develop coating method, that allow the visualization of collagen period. MATERIALS AND METHODS Unfixed mouse tail tendons were quickly dissected in filaments as thin as possible. Tissues were dehydrated in a graded acetone series, dried for two hours in high vacuum. They were then sputtered with 26 nm gold palladium (Polaron 5001 S.D.), or with 18 nm chromium (Plasma science Cr C 100 S.D.), or rotary shadowed with 2 m platinum /carbon (Baker BAF 301, two EK 552 E.B.G.), at -85. All instruments were equipped with film thickness monitors. Specimens were kept overnight in high vacuum and observed with a field emission Hitachi S 4000 SEM, at 20 kV. RESULTS Collagen period had a length of 64 nm in all specimens. At high resolution, in specimens coated with gold palladium, brightness and contrast were good. However particles of various dimensions were evident on the fibrils and the collagen period was partially masked with the thick metal covering. Fractures were evident: some of them, perpendicular to the collagen fibrils axis, were spaced each other a period length; others, parallel to the axis, rarely exceeded the collagen period length (Fig. 1A). In chromium-coated specimens, brightness and contrast were not satisfactory, where the covering was rather homogeneous. The period was evident and collagen fibrils gap and overlap zones were easily observable. In addition, in these specimens, fractures absolutely comparable with those observed with gold palladium were seen (Fig. 1B). In platinum/carbon-coated specimens, the brightness was very satisfactory and the covery homogeneous. Period was easily visible and gap and overlap zones were evident. The gap zone represented about 1/5 of the total period. No fracture could be seen in these specimens (Fig. 1C). At a relatively low magnification, the periodicity of the fibrils could be appreciated (Fig. 2). DISCUSSION Unfixed fragments were used in order to avoid artefacts produced by furation with aldehydes and tannic acid (both create artificial cross-links between collagen molecules) (2). From our results it emerges that gold palladium covering gives unsatisfactory results for its granularity. Collagen period was easily observable after chromium coating: gap and overlap zones beeing well distinguishable. Fractures observed in gold and chromium-covered specimens suggestively recall the arrangement of proteoglycans as results from TEM (3). Even though no subperiod was observed, platinudcarbon coating gave the best results because it allowed the identification of gap and overlap zones. These fidings might be related more to the coating temperature than to the metal used: according to Hermann and Muller (5,6) the metal grain size increases with heating. At variance with TEM findings, that showed a period of 67 nm and a gap zone representing 2/5 (4), according to our results the period measures 64 nm and gap zone only 1/5 of the total period. Even though several other factors may be taken into consideration, we believe that the shortening of the period and of the gap zone observed in SEM may be related to the fact that we employed unfixed tissues.

Context-aware computing is one of key problems of intelligent environment and the context-aware application has focused on providing services to users.Context-conflict often occurs when multiple users share limited resources at the same time in intelligent environment.The mathematical model of context-conflict is built based on fuzzy set and systematology.The context-conflict resolution policy is represented as finding the extremum of a constrained multivariable function.In desirable scenarios,this resolution policy can describe the context-conflict problem concisely and serve users without distracting or sacrificing others.This proposal for solving context-conflict situations simplifies development of context-aware applications.


ABSTRACT Title: The development of a methodology to measure and verifY the impact of a national solar water heating program.Title: The development of a methodology to measure and verifY the impact of a national solar water heating program. Author: Rene Pierre Coetzee. Promoter: Prof. U Grobler. School: School of Mechanical Engineering, North-West University (Potchefstroom Campus). Degree: Magister lngeneriae in Mechanical Engineering The School for Mechanical Engineering at the North-West University is home to one of South Africa's most established Measurement & Verification (M&V) teams. The team is involved with South Africa's electricity utility, Eskom, and their efforts to reduce the energy demand of the nation through Demand Side Management (DSM). One of the DSM initiatives in the residential energy sector is a National Solar Water Heating Program which encourages homeowners to purchase and install an Eskom accredited solar water heating system by means of a financial incentive. Massive financial investments have been incurred and it is only natural for stakeholders to question their return on investment. The need consequently exists to determine the impact of the National Solar Water Heating Program and establish whether it is being sustained. Before developing a methodology to measure and verifY the impact of a solar water heating program an in-depth study had to be done on M&V as well as the concepts around solar water heating itself. After considering financial, time and accuracy constraints it was decided that an M&V Solar Water Heating Application along with the M& V methodology be developed. The primary aim of the application was to simulate the electrical hot water demand caused by the electrical-backup elements of the solar water heating systems and thereby avoiding the logistically and financially impossible process of measuring the electrical demand. A high-level simulation application, based on energy balances, was developed with solar water heating system types, geographical locations, weather conditions, hot water demand profiles and installation positions as inputs. The outputs of the application were the uncontrolled, simulated electrical hot water demand and were compared to the actual measured electrical hot water demand of a solar water heating system located in Cape Town.


Photo-excited state in correlated electron system with spin-state degree of freedom is studied. We start from the two-orbital extended Hubbard model where energy difference between the two orbitals is introduced. Photo-excited metastable state is examined based on the effective model Hamiltonian derived by the two-orbital Hubbard model. Spin-state change is induced by photo-irradiation in the low-spin band insulator near the phase boundary. High-spin state is stabilized by creating a ferromagnetic bound state with photo-doped hole carriers. An optical absorption occurs between the bonding and antibonding orbitals inside of the bound state. Time-evolution for photo-excited states is simulated in the time-dependent mean-field scheme. Pair-annihilations of the photo-doped electron and hole generate the high-spin state in a low-spin band insulator. We propose that this process is directly observed by the time-resolved photoemission experiments.


Jarosites (KFe3(SO4)2(OH)6) are examples of minerals that are highly effective scavengers of toxic elements, and are abundant in acid rock drainage systems, acid sulfate soils, metallurgical wastes and other contaminated sites. The K, Fe and S sites can be filled by toxic elements such as Cd, Cu and Zn, but the mechanisms of this incorporation are not well understood.
We have used atomistic simulation methods to model the jarosite (102) surface and its interactions with Cd, Zn and Cu, in order to understand the mechanisms by which these potentially toxic elements are incorporated into the K-jarosite structure. Our results suggest that incorporation via a defect complex consisting of an impurity cation at the K site charge balanced by a K vacancy stabilises the (102) surface in the order Cu>Zn>Cd.


By the modern geological survey and data comprehensive analysis of silt muddy coastal zone,it is suggested that modern geological action,erosion and accumulation coexist on the west coast of Bohai Bay,China.At present,upper part of the intertidal zone is being accumulated,and meanwhile subtidal zone eroding,so intertidal zone is in the transitional period from aggrading to eroding.Based on further analysis of remote sense data and grain size data of sediment,the authosr discuss the influence factors of modern geological action and the source of sediment that aggraded coastal zone at west coast of Bohai Bay: the mud and sand coming from subtidal zone and shallows are the dominating source that result in deposited in the upper intertidal flat.In the end,authors presented future development tendency of tidal flat on west coast of Bohai Bay,and insisted that not only prevent accumulation but also the erosion should be payed more attention to in the coastal development.


ABSTRACT:Introduction: West Virginia is a state in which most counties are rural, as well as a state with multiple health disparities among its population. The purpose of this study was to determine the association of sleep duration and falls for non-institutionalized West Virginia adults, aged 40 years and above, using the National Sleep Foundation's definition of "may be appropriate" and "not recommended" sleep durations for specific ages.Methods: Behavior Risk Factor Surveillance System (BRFSS) 2018 data concerning West Virginia residents were extracted for sleep duration and number of falls within the previous year. Data were analyzed with Chi square and logistic regression analyses on falls.Results: There were 2780 participants, aged 45 years and above. Slightly more than half (51.0%) were female. In adjusted logistic regression analysis, the adjusted odds ratio for falls in participants who did not have the recommended sleep duration was 1.77; 95%CI: 1.38, 2.27; p<0.0001 as compared with participants who did have the recommended sleep duration.Conclusion: Inadequate sleep duration, based on age, was associated with ≥1 falls within the previous year in a West Virginia Appalachian population.


Looks at any cooperative design process as a decision-making process, i.e. as a non-deterministic process. The process is performed by responsible agents having the freedom to decide how to proceed according to their assessment of the situation they are faced to. However, the cooperative design process cannot be an ad-hoc and chaotic process. We look at it as a repeatable process made of steps resulting each of the application of the same pattern for decision making. The pattern views a decision as a choice of the way to proceed in a given situation to achieve an intention. An intention can be fulfilled in different ways depending on the situation being considered. We propose a process meta-model for describing such a pattern of decision making. This meta-model can also be used for modeling cooperative business processes, whether well-structured or ill-structured. In order to deal with a wide range of cooperative processes, we propose a single-process meta-model which provides the structuredness of predefined models and the flexibility of ill-structured processes.


A cycloolefin copolymer matrix was melt mixed with exfoliated graphite nanoplatelets (xGnP) and the resulting nanocomposites were foamed by supercritical carbon dioxide. The density of the obtained foams decreased with the foaming pressure. Moreover, xGnP limited the cell growth during the expansion process thus reducing the cell diameter (from 1.08 to 0.22 mm with an XGnP amount of 10 wt% at 150 bar) and increasing the cell density (from 12 to 45 cells/mm 2 with a nanofiller content of 10 wt% at 150 bar). Electron microscopy observations of foams evidenced exfoliation and orientation of the nanoplatelets along the cell walls. Quasi-static compressive tests and tensile creep tests on foams clearly indicated that xGnP improved the modulus (up to a factor of 10 for a xGnP content of 10 wt%) and the creep stability.


Abstract The slip systems observed in a number of crystal structures common amongst metals and simple ceramic materials are examined to see whether they allow the crystal to undergo an arbitrary strain without change of volume. For most materials, other than f.c.c. and b.c.c. metals, there are insufficient independent slip systems. The condition under which cross slip can give rise to extra independent systems is stated. The results explain in a natural way recent experimental findings on the ductility of polycrystals with the sodium chloride structure.


We summarize published hole transit-time measurements for hydrogenated amorphous silicon, microcrystalline silicon, and light-emitting nanoporous silicon in terms of drift mobilities and dispersion parameters. For amorphous and microcrystalline silicon, the anomalously dispersive measurements are broadly consistent with multiple-trapping by bandtail traps with an exponential distribution of energy depths. One unexplained result has been that the trap emission prefactor frequency ν is about 1000 times smaller in microcrystalline silicon than in amorphous silicon. We present a model incorporating both detailed-balance effects and a previously proposed Meyer–Neldel variation of ν with trap-depth; the model accounts for the factor 1000. We discuss general trap distributions incorporating variations of both trap depth and prefactor frequency; a model for which dispersion is due entirely to prefactor variation accounts for measurements on nanoporous silicon.


The utility model relates to a hydrogen peroxide gas sterilizer, which is used for carrying out sterilization in isolated spaces and vessels. The hydrogen peroxide gas sterilizer comprises a shell, an air outlet pipe, vaporizing chamber components, liquid atomizing components and an electrical control cabinet, wherein the liquid atomizing components comprises an atomizing solenoid valve, a gas-liquid mixing tank, a micro-air compressor, an air inlet solenoid valve, a liquid inlet solenoid valve, a small metering pump and a hydrogen peroxide solution barrel; the hydrogen peroxide solution barrel is connected with the gas-liquid mixing tank through the small metering pump and the liquid inlet solenoid valve; the micro-air compressor is connected with the gas-liquid mixing tank; and the gas-liquid mixing tank is connected with a spraying nozzle in a vaporizing chamber through the atomizing solenoid valve; the vaporizing chamber components comprise a vaporizing chamber, a vaporizing plate, a heater and a axial flow high-pressure ventilator; the heater is a PTC cellular heater; the vaporizing plate at which micropores are distributed is attached to the PTC cellular heater; the spraying nozzle corresponds to the vaporizing plate; the top of the vaporizing chamber is connected with the axial flow high-pressure ventilator; and the air outlet of the high-pressure ventilator is connected with the air outlet pipe. The hydrogen peroxide gas sterilizer has the advantages of reasonable structure and good sterilization effect.


We consider a polaronic model in which impurity fermions interact with background bosons in a dipolar condensate. The polaron in this model emerges as an impurity dressed with a cloud of phonons of the dipolar condensate, which, due to the competition between the attractive and repulsive part of the dipole-dipole interaction, obey an anisotropic dispersion spectrum. We study how this anisotropy affects the Cerenkov-like emission of Bogoliubov phonon modes, which can be directly verified by experiments in which a dipolar BEC moves against an obstacle. We also study the spectral function of impurity fermions, which is directly accessible to the momentum resolved rf spectroscopy in cold atoms.


This paper introduces the robust D-stabilizing output-feedback H(subscript ∞) control for a uncertain system. Using the method of Linear Matrix Inequality (LMI), the sufficient condition and design idea for robust D-stabilizing output-feedback controller are deduced from the quadratic stability. The method in this paper is conservative but simple and efficient. It is also applied to the mulitiobjective robust control. Finally, the simulation proves the method is right.


Tribological properties of blends of melamine-formaldehyde resin (MFR) with low density polyethylene (LDPE) containing 1, 5, 10, 20, 25 wt% MFR were investigated. We have determined sliding wear by multiple scratching along the same groove using a micro scratch tester. Instantaneous penetration depth is lowered by the MFR addition to LDPE. However, there is less viscoelastic recovery and the residual (healing) depths increase with increasing MFR concentration. Microindentation hardness increases along with the MFR content. Since MFR is only partially miscible with LDPE, MFR-rich islands in the PE matrix offer more interfaces and so increase hardness. Friction determined with a pin-on-disk tribometer using silicon nitride balls as a function of MFR concentration shows a minimum. The result is explained in terms of surface morphology seen in scanning electron microscopy. At the same time, all blend friction values are lower than for neat LDPE. Wear determined in the pin-on-disk tribometer decreases along with the MFR concentration increase. Thus, pin-on-disk wear and friction show different faces of blends tribology. Blending can be used to improve tribological properties of LDPE. POLYM. ENG. SCI., 2008. © 2007 Society of Plastics Engineers


Anomalous diffusion is discussed in the context of quantum Brownian motion with colored noise. It is shown that earlier results follow simply and directly from the fluctuation-dissipation theorem. The limits on the long-time dependence of anomalous diffusion are shown to be a consequence of the second law of thermodynamics. The special case of an electron interacting with the radiation field is discussed in detail. We apply our results to wave-packet spreading.


Crystallization and multicomponent crystal formation of active pharmaceutical ingredients Baclofen and Phenibut with dicarboxylic acid co-formers are discussed. The crystallization process of several crystalline entities is elucidated via single crystal—as well as powder X-ray—diffraction, followed by thermal analysis and phase stability studies over time. Both APIs form increasingly complex crystalline phases with co-formers malic and tartaric acid, where phase purity of a desired compound is not necessarily a given. Therefore, the influence of different solution and milling environments during crystallization on the outcome is studied. Emphasis is laid on how molecular influences such as the chirality, propensity to form hydrates as well as low solubility of Baclofen and Phenibut impede attempts to gather high-quality single crystals. The results highlight that targeted crystallization of these compounds with dicarboxylic acids can be difficult and unreliable.


With South Africa being one of the most water-scarce countries in the world, the limited water resources available must be well preserved and consciously utilized. Thepurpose of the research was to quantify the daily amount of groundwater pumpedout of the University's basement area, determining the impact that it has when discharged into the surrounding environment as well as the socioeconomic benefits it holds for the community and theUniversity. By analyzing data recorded from installed meters, it was determined that there was an average of 192.89m of groundwater extracted daily from March 2016 to February 2019. It was established that a total of 55.8% of this water was not utilised by the University and was discharged into the municipal stormwater system which was essentially wasted. Further investigations found that the installed meters did not account for all of the water flowing out of the basement area into the stormwater drain and that the amounts are greater than anticipated.The groundwater's point of discharge from the basement area was identified and it was discovered that due to the long term discharge of water at this point, a crack has formed in the pavement adjacent to the road surface. Remedial action is required in this area to prevent further deterioration of the road surface which may become a safety hazard for motorists. It was also determined that this groundwater possesses the potential to save the University expenditure on municipal water expenses and these savings can be utilised to improve the conditions on campus for the students. This groundwater also holds vast amounts of socio-economic potential to improve the lives of many poor individuals in the surrounding community.


Nonlinear-optics activities range from the fundamental studies of the interaction between matter and radiation to the development of devices,components,and systems of tremendous commercial interest for widespread applications in optical telecommunications,medicine,and biotechnology.During recent years,research efforts in nonlinear optics focused on source technology,light communication technology and engineering or enhancing nonlinearities.As an aspect of laser source,high field nonlinearities and Attosecond technology obtained huge progress widely.Importantly,more and more groups are employing new white-light-laser sources for their experiments.In the area of light communications,nonlinear propagation of light and engineerable group-velocity dispersion(GVD) in engineered waveguides become focus.Moreover,nonlinear material is the basic of nonlinear science.It is a new hot spot to manipulate nonlinear response and enhance nonlinearities by Microcavity and surface plasmonic.

Gravitational lensing – the deflection of light rays by gravitating matter – has become a major tool in the armoury of the modern cosmologist. Proposed nearly a hundred years ago as a key feature of Einstein's theory of general relativity, we trace the historical development since its verification at a solar eclipse in 1919. Einstein was apparently cautious about its practical utility and the subject lay dormant observationally for nearly 60 years. Nonetheless there has been rapid progress over the past twenty years. The technique allows astronomers to chart the distribution of dark matter on large and small scales thereby testing predictions of the standard cosmological model which assumes dark matter comprises a massive weakly-interacting particle. By measuring the distances and tracing the growth of dark matter structure over cosmic time, gravitational lensing also holds great promise in determining whether the dark energy, postulated to explain the accelerated cosmic expansion, is a vacuum energy density or a failure of general relativity on large scales. We illustrate the wide range of applications which harness the power of gravitational lensing, from searches for the earliest galaxies magnified by massive clusters to those for extrasolar planets which temporarily brighten a background star. We summarise the future prospects with dedicated ground and space-based facilities designed to exploit this remarkable physical phenomenon.

This article focuses on the question of how regulation can be best designed to encourage technological innovation. Most scholarship in this area applies standard economic analysis to evaluate the impact of various forms of regulation on technological innovation. We reject that approach as too narrow, drawing instead upon principles of evolutionary economics. The basic premise of the article is that a firm's technology choices—and its response to regulation intended to shape those choices—are influenced by other actors (such as suppliers and competitors), by external social and legal institutions (e.g., industry standards and norms) and by the firms' internal structure (such as communication channels.) Regulators seeking to encourage innovation must first understand the industry sector's "selection environment;" that is, the socio-economic environment created by that network of actors, institutions, and routines. We demonstrate the selection environment approach in a case study of the dry cleaning sector, a leading source of toxic emissions in Southern California. Professional drycleaners have been slow to adopt alternative non-polluting cleaning technologies. Relying upon surveys and interviews we conducted of cleaners, equipment vendors, and regulators, we construct a conceptual model of the sector's selection environment. We then use that model to identify barriers to innovation, and to evaluate several policy tools intended to overcome those barriers. Our analysis is a cautionary tale for those who support broad use of market-based regulation such as economic incentives and information strategies. In the selection environment we studied, traditional command and control regulation is likely to lead to broader diffusion of the new environmentally-beneficial cleaning technologies than market-based approaches, and at less social cost.

Abstract. A dual-wavelength method in high accuracy polarimetry has been successfully tested and applied to measure optical activity (OA) of nonlinear crystals. In proposed polarimetric scheme two neighboring semiconductor laser wavelengths (635 and 650 nm) are used, which increases number of parameters measured simultaneously and improves the data processing. By neglecting dispersion of eigen wave ellipticity in crystals, more efficient elimination of the systematic errors, in comparison with the known HAUP technique, is possible. We have tested our experimental setup on optically inactive lithium niobate crystal and obtained OA in the perpendicular to the optical axis direction for quartz and DKDP crystals.


cerebral xanthomatosis nor dyslipoproteinemia. The xanthomas were removed by curettage and CO2-laser therapy. Consistent complex decongestive therapy (CDT) with manual lymphatic drainage, bandaging and compression garments were applied both preand postoperatively. Two years after commencing CDT, no further xanthomas have appeared. The association of papular xanthomas in chronic lymphedema is found especially in adolescents with primary lymphedema. There is no sex preference. The yellowish to red-brown papules with smooth or verruciform surface and a tendency to confluence develop some months to a few years after manifestation of the lymphedema. The histological pattern is characterized by subepidermal accumulation of foam cells and signs of lymph stasis. There is normolipidemia and no association with other diseases. Hunter et al. proposed that the development of xanthomas on lymphedema result from the phagocytosis of lipoproteins by tissue macrophages, because lipoproteins accumulate secondarily in the intercellular tissue clefts due to hydrostatic pressure or lymphatic obstruction. In patients with neither lipoprotein abnormalities nor associated systemic diseases, local dermal tissue abnormalities seem to play the major role in normolipemic xanthoma formation. Chronic lymphedema can selectively damage a cutaneous district and facilitate the onset of neoplasms, infections and immune disorders. The alteration of immunity is based on abnormal trafficking of immunocompetent cells through the lymphatic channels and altered signaling of neuromediators. This local immune imbalance may lead to an increased leakage of accumulated lipoproteins into the dermis. In terms of general pathology, the designation ''lymphostatic xanthomatosis'' defines a potential sequela of chronic primary lymphedema. Therefore, inappropriate or missing therapy of the lymphedema may be etiological for frequent relapses. The surgical therapeutic options consist of curettage, excision, electrodissection or laser removal. However, xanthomas can only be resolved permanently in combination with a consistent complex decongestive therapy.


The future Large Hadron Electron Collider (LHeC) would enable collisions of an intense electron beam with either protons or heavy ions at the High Luminosity-Large Hadron Collider (HL- LHC). With a center of mass energy greater than a TeV and a high luminosity, the LHeC would be a new-generation collider for deep-inelastic scattering (DIS) and a significant facility for precise Higgs physics, complementing pp and electron-positron colliders. Anomalous hadronic decay signatures of the Higgs Boson, such as those into three or more partons, are challenging to detect at the LHC due to high background rates, but they may be observable at the LHeC. This paper presents the expected sensitivity of the LHeC for the decay channels $H \rightarrow 3jets$ and $H \rightarrow 4jets$, assuming an integrated luminosity of 1 ab$^{-1}$. Our analysis indicates that upper limits on the branching ratio of the Higgs Boson of 0.35 and 0.17 at 95% confidence limit for these processes are possible.

A novel nonionic surfmer, AGE-TX-100, was synthesized by the epoxide ring-opening reaction of allyl glycidyl ether and polyoxyethylene (10) octylphenyl ether (TX-100). Then a novel copolymer, acrylamide (AM)/acrylic acid (AA)/AGE-TX-100, was synthesized with AM, AA, and AGE-TX-100 in aqueous solution through free-radical random polymerization. The structures of the novel surfmer and copolymer were characterized by IR and 1H-NMR. The results of the salt-resistance tests and the rheological tests indicate that the copolymer had good salt tolerance, thermal stability at high temperatures, and shearing resistance under high shear rates. The environmental scanning electron micrographs showed that the copolymer could form a tighter three-dimensional network structure than partially hydrolyzed polyacrylamide (HPAM) in aqueous solution. Compared with the HPAM solution, the copolymer solution showed a good ability to emulsify organic components. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 41024.


Philadelphia-chromosome positive acute lymphocytic leukemia (Ph+ALL) is an intractable disease. After the development of imatinib, a tyrosine kinase inhibitor, the outcome of chemotherapy, especially remission induction rate, has been improved. Its long-term prognosis is, however, still poor, mainly because of high relapse rate, and therefore allogeneic stem cell transplantation (allo-SCT) is considered to be the only curative option. Recently, adopting the idea of minimal residual disease (MRD) in a treatment strategy of Ph+ALL as well as chronic myeloid leukemia (CML), it was reported that even in hematologically complete remission (CR), positive MRD at allo-SCT was a strong predictor for relapse after allo-SCT. Although it is ideal to perform allo-SCT in MRD-negative condition, it is sometimes difficult to achieve such treatment effect, despite the administration of imatinib. There are some reports dealing with posttransplant imatinib administration, but its efficacy and administration methods are still controversial. To evaluate the effect of posttransplant imatinib administration, we retrospectively analyzed 34 Ph+ALL patients who received allo-SCT at 7 transplant centers in Japan between January 1989 and September 2007. Study admission criteria were allo-SCT for the first time, non-manipulation and MRD positive at allo-SCT. Median age at allo-SCT was 40 years old, 18 patients were transplanted in hematological CR, 14 patients were transplanted from unrelated donors and 20 patients from relative donors. Seven out of 34 patients received posttransplant imatinib administration. We proposed two strategies for posttransplant imatinib administration. One was early administration, where imatinib was administered upon detecting MRD after allo-SCT. The other was prophylactic administration, where imatinib was administered as soon after allo-SCT as possible. Overall survival was significantly better in patients with posttransplant administration (29.6% in patients without posttransplant imatinib vs. 66.7% in those with posttransplant imatinib at 3 years, p=0.03). In contrst, there was no significant difference in event-free survival (EFS) between two groups (29.6% in patients without posttransplant imatinib vs. 0% in those with posttransplant imatinib at 3 years, p=0.29).(Figure) As for details of MRD in patients with posttransplant imatinib administration, the duration of negative MRD was 9 months, 6 months, and 2 months or more in the early administration group, while in the prophylactic administration group it was 29 months, 12 months, and 9 months or more. It seemed that the duration of negative MRD was longer in the prophylactic group, but in all patients whose observation periods were longer than 1 year, MRD became positive in both groups and this lead to hematological relapse. The fact that posttransplant imatinib administration, even prophylactic administration, was no significant effect on event-free survival revealed the limitation of imatinib administration after allo-SCT. Although it is a great thing to achieve longer duration of negative MRD, posttransplant imatinib administration could not be a fundamental solution for Ph+ALL patients whose MRD was positive at allo-SCT. Considering the cure for Ph+ALL, MRD at allo-SCT has a profound impact on long-term EFS and posttransplant intervention seems to have limitation. To achieve a fundamental solution, the key would be to achieve negative MRD at allo-SCT, for example, by using new drugs, like nilotinib, dasatinib and other secondgeneration tyrosine inhibitors in case imatinib was inadequate to achieve negative MRD. MRD-based strategy is essential for a cure of Ph+ALL.

A morphological and anatomical study of the mycorrhizas on Pinus strobus L. was conducted on seedlings excavated from St.-Williams nursery in southern Ontario. Micro- and macro-scopic characters were used to classify the morphotypes into complexes and, when possible, genera and species. An E-strain fungus, fungi from the Mycelium radicis atrovirens (MRA) complex, and an unidentified ascomycetous "red-type" fungus formed ectendomycorrhizal (EECM) associations, while Tuber sp., Hebeloma sp., and Thelephora terrestris formed ectomycorrhizal (ECM) associations in the nursery. Cultures of Hebeloma sp., the E-strain fungus, Tuber sp., and two morphologically distinct MRA fungi (MRA1, later identified as Phialophora finlandia Wang & Wilcox, and MRA2, unidentified) were isolated from field-collected morphotypes and re-inoculated onto Pinus strobus seedlings grown in semisterile pot cultures for 4 months. In the resynthesis experiment, the E-strain fungus formed EECM with sparse intracellular colonization, and Tub...

Jean Masini, The Untouchable Multinationals ; The multinational companies must maximize products in a conflictual environment. As they are a major source of these tensions, the multinationals must constantly find ways to adapt their economic strategies to the political conditions created by them. Although national governments follow these adaptations, attempting to profit from them, it is difficult to anticipate decisions that are made privately. Nevertheless, the creation of free-trade zones in Western Europe and North America represents parallel attempts to increase the competitive position of European and North American multinationals in relation to those of Japan. But will this strategy be successful ?

We performe first-principles density functional theory calculations to investigate the stability and mechanical properties of various HfHx (0 ≤ x ≤ 1) phases. For pure Hf phases, the calculated results show that the HCP and FCC phases are mechanically stable, while the BCC phase is unstable at 0 K. Also, as for various HfHx phases, we find that H location and concentration could have a significant effect on their stability and mechanical properties. When 0 ≤ x ≤ 0.25, the HCP phases with H at (tetrahedral) T sites are energetically most stable among various phases. The FCC and BCC phases with H at T sites turn to be relatively more favorable than the HCP phase when H concentration is higher than 0.25. Furthermore, our calculated results indicate that the H solution in Hf can largely affect their mechanical properties such as the bulk moduli (B) and shear moduli (G).


Summary The occurrence of spontaneous fibrinolysis has been investigated in various medical diseases, e. g. myocardial infarction, cerebral stroke, phlebothrombosis, pulmonary embolism, metastasing cancer, and others. Serum from patients has been tested for fibrinolytic break-down products by use of immunodiffusion and Immunoelectrophoresis with double-diffusion. It was anticipated that positive results might provide useful diagnostic, prognostic, and therapeutic information, particularly in patients with myocardial infarction. However, there is no apparent correlation between the occurrence of spontaneous fibrinolysis and the course of disease. In patients with haemorrhagic diathesis the tests give useful information, but in the remaining groups tested, the significance of occurring fibrinolytic break-down products cannot yet be evaluated.


This paper examines the effects of fiscal policy on private consumption. The paper evaluates the assumption that the effects of fiscal policy are dependent on the public sector's financial situation, which changes the private sector's income expectations. For this purpose regression equations are run with international data. From the international evidence it is found that every component of fiscal policy, public consumption, taxes, and transfers, may have regime-specific effects related to the financial balance in the public sector. Regressions of Finnish data show that private sector's income expectations may have played an important role in the private consumption changes of the early 199Os. In light of the international estimations, it is also found that changes in the unemployment rate may have regime-specific effects on consumption.


Five chiral and achiral copper(II) carboxyphosphonates, namely, [Cu(4-cppH)(2,2′-bipy)(H2O)] (1: R-1 and S-1), [Cu9(4-cpp)6(2,2′-bipy)6] (2), [Cu3(4-cpp)2(2,2′-bipy)2] (3), [Cu3(4-cpp)2(1,10-phen)2]·4H2O (4), and [Cu(4-cppH)(1,10-phen)]·H2O (5), had been hydrothermally synthesized. Among them, 1 showed an unexpected 1D chiral helical chain from achiral carboxyphosphonate ligand by spontaneous resolution. In 2, the interconnection of {CuN2O3}, {CuO4}, and {CPO3} polyhedra formed a 1D chain. Such chains were further connected to a 2D layer through the carboxyphosphonates ligands. Compounds 3 and 4 were isostructural and exhibited a 2D layer, which was constructed from {CuO3N2}/{CuO4} polyhedra and the carboxyphosphonate ligands. In 5, the interconnection of neighboring {CuN2O3} polyhedra formed a dimer. These dimers were connected with the carboxyphosphonate ligands to form a chain. Interestingly, the homochiral copper(II) phosphonate (R-1 or S-1) could be obtained by utilizing the (+)-cinchonine or (−)-cin...


The effects of culture factors (e.g. ratio of NH~+_4/NO~-_3; nitrogen concentration; MS strength; sugar types and sucrose) were studied to establish the system of quick propagation of Gysophila paniculata L. in vitro and the controlling of vitrified seedlings. The results indicated that the MS medium containing 20/40 mM of NH~+_4/NO~-_3 was fit for the mass proliferation, and the growth state of seedling was good. The 90 mM of nitrogen or two folds strength of MS medium could obtain mass healthy seedlings. 30 g/L of sucrose had facilitation to the proliferation growth and could inhibit the occurrence of vitrified seedlings.


This chapter considers the famous opposition between "letter" and "spirit". The dictum of Paul, famously rendered by the King James Version: "For the letter killeth, but the spirit giveth life" has itself been appropriated in their different ways by lawyers and theologians. It argues that the historical background indicates that the real dispute was one over the semiotics of revelation: through what means was the divine will made manifest and to what extent was that form of communication both effective and accessible to human reason? The history of division between Judaism and Christianity may be viewed as a conflict over the acceptable forms of communication of divine message. When discussing biblical law, the historical and social realities of the period must be distinguished, and claims of the authors of the biblical texts, which frequently reflect their own, normative views. The chapter focuses is on the latter, rather than the former.Keywords: biblical law; Christianity; dictum of Paul; divine message; historical observations; Judaism; letter; revelation; spirit


MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) neutrino experiment on the Booster Neutrino Beamline at the Fermi National Accelerator Laboratory, with an 85-tonne active mass. One of MicroBooNE's primary physics goals is to investigate the excess of electron neutrino events seen by MiniBooNE in the [200-600] MeV range. MicroBooNE will constrain the intrinsic electron neutrino component of the beam by measuring the muon neutrino spectrum. Several low-energy excess analyses are taking place in parallel, using independent reconstructions and selection schemes. This paper will focus on a low-energy excess analysis that makes use of deep learning algorithms applied to the high-resolution images provided by the MicroBooNE LArTPC. We present a novel 3D event reconstruction based on computer vision tools and a stochastic search algorithm, yielding a 2.2% energy resolution for 1μ1p muon neutrino interactions in the [200-1500] MeV range.

The Sisters are flanked by a number of monumental barks painted by the great artists who have interpreted the Djang'kawu Sisters creation narrative over a sixty year period: Mawalan1 Marika, Wandjuk Marika, Mawalan 2 Marika, Mathaman Marika and Wanyibi Marika. This comprehensive exhibition pulls together a number of significant paintings, sculptures, fibreworks and prints based on this story, which takes place around the site of Yalangbara, near Yirrkala in north-eastern Arnhem Land. It also presents a history of creative and spiritual custodianship by the Marika family of the Rirratjingu clan and like all Yolngu art from eastern Arnhem Land, it is a declaration of rights to their land.


During game play a variety of undesired emotions can arise, impeding players' positive experiences. Adapting game features based on players' emotions can help to address this problem, but necessitates a way to detect the current emotional state. We investigate using input parameters on a graphics tablet in combination with in-game performance to unobtrusively detect the players' current emotional state. We conducted a user study with 48 participants to collect self-reported emotions, input data from the tablet and in-game performance in a serious game teaching players to write Japanese hiragana characters. We synchronized data, extracted 46 features, trained machine learning models, and evaluated their performance to predict levels of valence, arousal, and dominance modeled as a seven class problem. The analysis shows that random forests achieve good accuracies with F1 scores of .567 to .577 and AUC of .738 to .740, while using input features or in-game performance alone leads to highly decreased performance. Finally, we propose a game architecture that is able to react to undesired emotion levels by adaptive content generation in combination with emotion recognition.

The subject of this paper is the fracture characteristics of single particles of polymethylmethacrylate (PMMA) or polystyrene (PS) when they were impacted on a target by using an air gun. As a result of experiments a new method of measuring the specific fracture-surface energy was also obtained. From the total energy balance of the impacted particle and the target, the specific fracture energy for PMMA and PS was calculated from four kinds of measured values, namely impact velocity, rebound velocity, deformation, and impact force of a collided particle. The specific fracture energy was formulated as a function of the impact velocity of a particle. The specific fracture-surface energy was also calculated from the values of the specific fracture energy and the increase of specific surface area. The values of the specific fracture-surface energy at the optimum impact velocity were estimated to be 1.5-2.0 kJ/m2 for PMMA and 3.0-3.4 kJ/m2 for PS.

heard the slogan "No Voice is Louder than the Voice of the Intifada". I was born at the peak of the 1988 Intifada, when this slogan first appeared. I became aware of it during the second uprising, when the slogan reemerged at the start of the millennium. When I chose the topic of my dissertation – the impact of a prevalent ideology in determining the options of sociological research in Palestinian universities – I found that the slogan summarised how the existing national ideology works against critical visions in social sciences and tries to silence them. In my research I found that the slogan was a modification to one that existed during times of tyranny in Arab countries in the past century – "No Voice is Louder than the Voice of the Battle". Ever since I was born, I've been living through the "battle" in which no other voice should prevail. This is what happens when you live in a conflict that has not been resolved for more than 70 years. I live in Ramallah in the West Bank, an area that is subject to Israeli military occupation, according to the UN, since 1967. During this time there have been national movements working towards ending the occupation, but these have transformed into an authority that has signed a peace agreement with Israel that hasn't led to peace. Instead, understandings were reached that resulted in administrative and security co-ordination. At various times, this has led to periods of calm, with economic opportunities and cultural activity which were supported internationally. It seemed as if the battle's voice had receded or faded away. Yet the administration maintained the battle discourse, which seemingly must remain above all others.
