As the observation of 19 Scripture versions from the years 1632–1739 shows, the notion of Estonian negation changed a lot during the translating process of Estonia's fi rst full Bible. In North Estonian translations until the middle of the 1680s, German-like negation was often used instead of genuine Estonian forms: indicative negation was formed by merely adding a negative particle to the affi rmative; sometimes mitt e, "not", or a pronoun was the only negative marker. Such forms were, for the fi rst time, regularly replaced by genuine Estonian negation during the Pilistvere Bible conference in 1687. German-like negation was eliminated even more decisively in two Bible versions compiled immediately after this meeting: in the thoroughly edited New Testament by Johann Hornung, and in the Old Testament translated by Andreas and Adrian Virginius. From then on, such a choice of forms was preserved in North Estonian translations. In South Estonian texts, genuine Estonian forms dominated from the start. In South Estonian translations, the negative particles ei and es were used from the outset. In North Estonian texts, ep was the principal negative particle until the middle of the 1680s. With the translations by Virginius and Virginius, and Hornung, ei also became the principal negative particle in the North Estonian tradition. To a small extent, translators also began to again use es ~ is, which was common in the North Estonian sermons that were compiled by Georg Muller in the fi rst years of the 17th century. In prohibitive forms, the negation word ara remained the same in all persons before the 1680s. Then, for the fi rst time, diff erent forms of this verb were used by Hornung (argu in the third person), by both Virginius and Virginius, and by Hornung (arge in the second person plural). The ancient Finno-Ugric negative verb form e- occurred in the Bible translations extremely rarely, only in North Estonian texts and only in fi rst 137 person singular (en) and third person plural (evad). In the earlier sermons of Muller, instances of the negative verb in fi rst person plural (emme) have also been found.

Oxide electrolysis is the main way to produce metal neodymium and other rare earth alloys.Electric energy consumption is the big part in course of working,so it is very important to study the energy's going and to know the relationship in the manufacturing process.In this paper,the strike off of energy in 3000A Nd electrolytic cell is calculated and the radiating balance of electrolytic cell is analyzed.The results provide guidance for development of electrolytic cell and energy saving and cost reducing in practice.


This empirical research seeks to evaluate purchasing practices in Taiwan based on survey data collected from companies located in that country. A research model is presented and tested using structural equation modeling. The model includes three factors: purchasing risk taking, purchasing knowledge and skills, and strategic purchasing. The research findings indicate that purchasing risk‐taking impacts purchasing knowledge and skills and purchasing knowledge and skills impacts strategic purchasing. Also, the study finds that the relationships among risk taking, purchasing knowledge and skills and strategic purchasing for high performing firms are stronger than for low performing firms.


How to characterize and segment the different textures in an image is a key problem of image processing. All kinds of approaches have been proposed, among which some innovative methods were suggested base on fractal theory. The gray value of images can be mapped to a surface which could be characterized usually by fractional Brownian motion, and thus the fractal dimension were adopted to denote the roughness of different textures and their self-similarity quantitatively. The process of computing the fractal dimension of textures in an image was firstly discussed based on FBM models and then a novel algorithm was suggested to improve the efficiency of calculation, in which only those pixels that lying on the right and bottom edges of the square surrounding window would be considered. When sliding a window with a certain size on an image, the fractal dimension of the window can be calculated and applied to denote the fractal dimension of the center pixel of the window. Thus a fractal dimension image could be generated by mapping the fractal dimension of each pixel. The transformation from an image to its fractal dimension image bring forward a new beginning for further image process and has been investigated and validated through analyzing some SEM images. It's demonstrated that the fractal dimension of textures is little affected by the brightness and contrast of images but determined mostly by the structure of textures. Consequently fractal dimensions could characterize different textures more stably.


Advocates have suggested that the principles of community development can, and should, be used to increase the community connections of stakeholders with disabilities. Recently, the authors successfully implemented an approach that applied community development principles and practices with citizens with disabilities. To this end, the University Centers for Excellence in Developmental Disabilities Education, Research, and Service at the University of South Carolina School of Medicine and Louisiana State University Health Sciences Center collaborated during a 33‐month grant project designed to implement a community development model guided by five distinct core elements. The goal of this project, "The South Carolina and Louisiana Community Development Project," was to implement a community development process in four communities across two states that would use community coalitions to enhance community connections for all stakeholders. This paper describes the coalition‐building model used in this project, including its methodology with frameworks for technical assistance, quality indicators, and person‐centered outcomes. In illustration of the model, this paper presents case studies that summarize the results of the four participating coalitions, including coalition‐specific milestones and opportunities for participation and contributions by stakeholders with disabilities. Valuable lessons learned about coalition‐building and community connections for stakeholders with disabilities are presented. Finally, project findings, which offer contributions to existing research, accumulated knowledge, and recommended practices, are discussed.


Much discussion of electoral integrity focusses on new democracies. This paper explores the determinants of electoral integrity in a major established democracy in order to begin to identify drivers of electoral integrity for comparative scholars to exploit further. It does so through a novel measure of electoral administration in Britain which is brought together with comprehensive data on spending on electoral administration, whether concurrent elections were being held, size of electorate, number of constituencies administered, type of administration overseeing local electoral administration, and various socio-economic measures. The results establish a range of relationships to electoral integrity which will inform subsequent debates on election quality in other democracies, whether advanced or otherwise. In particular, the findings point to the importance of administrative resources in delivering electoral integrity in advanced democracies.


The effect of selected organic pigments on the supermolecular structure of isotactic polypropylene (IPP) fibre has been investigated. For the present work, three organic pigments of different molecular and supermolecular constitution were selected. Undrawn fibres with a minimal technological degree of drawing and fibres at draw ratios of 2, 4 and 5 were examined. The supermolecular structure was explored using small-angle X-ray scattering (SAXS). From the SAXS patterns the one-dimensional intensity function and the correlation function were determined. The parameters characterizing the supermolecular structure of the fibre, i.e. long period and invariant, were assessed. It was found that a lamellar structure develops during fibre formation. A regular lamellar structure is formed irrespective of the presence of pigments. On drawing fibres the high regularity of the lamellar structure decreases. In the drawing process the pigments are at the origin of micropore formation.


It is shared by several critical studies that Pietro Bembo's personal relationship with the feminine world exerted a great influence on the choice of theme and the writing of Gli Asolani . Much of the information we have about Bembo's personal life comes from his private letters wich were first published in 1552, in a five-volume Venetian edition at Scotto that included the Epistolarum familiarium Libri VI , in Latin, plus four volumes of letters in volgare , divided per recipient: the first to pontiffs, cardinals and clergymen, the second to Venetian friends, the third to gentlemen and friends in general, the fourth to women Among the recipients of the letters to women are Maria Savorgnan, whose loving relationship with the author will mark the history of the first edition of Gli Asolani , and Lucrezia Borgia, to whom Bembo will dedicate the editio princeps of the dialogue in 1505. In the next pages, we will discuss the author's relationship with Maria Savorgnan and Lucrezia Borgia and the intellectual affinity at the base of their affective bond. This work was carried out as part of the research project, Men for Women. Voces Masculinas en la Querella de las Mujeres for which we have translated into Spanish some passages from Pietro Bembo's Gli Asolani and have carried out a gender perspective study (SUADONI; SANNA, in press).


Abstract The habitat and population characteristics of the Maral, Cervus elaphus maral Gray, 1850, were studied in Golestan National Park, Iran, from 1975 to 2003 (but more intensively from 1976–1978) in the three vegetation types present; Caspian deciduous forest, transition zone, and steppe. Forest meadows and the transition zone were the preferred habitats. Hahn's census method and pellet group counts gave a population number of 1897–2096 Marals during 1976– 1978. Since then the population size has declined, to 500 in 2003. The average Maral group size was 4.6. The sex ratio among adults was 27 stags per 100 hinds. The number of calves produced per 100 hinds was 28. The annual mortality rate was 13.9% and life expectancy was 6.7 years. The decline of the Maral population in Golestan National Park was correlated with a similar trend in the Maral population in the Caspian forest (Hyrcanian region). Illegal hunting, road kill and livestock grazing have been identified as the major factors which affect the Maral population adversely.


SUMMARY An investigation was carried out into the potential of tylosin and terramycin fermentation wastes as fertilizers for tomatoes. Each waste was added at concentrations equivalent to 1 tN/ha to John Innes base compost. Each waste provided the sole source of nitrogen for the crop. Controls were set up with inorganic nitrogen applied at 1 tN/ha and 0·2 tN/ha, the quantity of nitrogen normally found in John Innes potting compost. Comparisons were also made between wet and dry terramycin waste. Each treatment was added to normal John Innes base compost and John Innes base minus one part peat, to determine the potential of antibiotic fermentation waste as a peat substitute. The size, weight and antibiotic content of the tomatoes produced were determined. The use of antibiotic fermentation wastes delayed the onset of tomato production due to the slow release of nitrogen. Final yields were not significantly different from the control treatments except in the tylosin treatment which produced the highest yield, both in terms of weight and numbers, of all the treatments. The reduction in the amount of peat in the base compost only appeared to affect the control treatments, where a delay in the onset of tomato production was seen in the control low in peat. No antibiotic was detected in any of the tomatoes.

The further high efficiency exploitation of gas reservoir is very difficulty because of the complexity of the spatial distribution of single sand body in S area,Sulige Gas Field. Based on the regional geology, sedimentary facies, well logging, well drilling and core data in S area, the study of high-resolution sequence stratigraphy and electrofacies in the low Shihezi Formation of HE-8 member in the area was carried out by adopting the scheme of multistage sequence cycle division and associates analysis-technique of electrofacies and guided by the theory, technique and method of Cross's high-resolution sequence stratigraphy. This paper not only recognizes 2 long-term, 4 mid-term and 11 short-term base level cycle sequences after fine classification and correlation but also establishes stratigraphic correlation framework with High-resolution in this area. The division of sedimentary facies and establishment of subsequence correlation frameworks above mentioned enhance the understanding for the discipline of the vertical-horizontal distribution of sand body in S area, which make geological foundations for the planning of reasonable cycling exploitation- development scheme in next step.


[1] This paper describes a statistical clustering approach toward the classification of cloud types within meteorological satellite imagery, specifically, visible and infrared data. The method is based on the Standard Deviation Limited Adaptive Clustering (SDLAC) procedure, which has been used to classify a variety of features within both polar orbiting and geostationary imagery, including land cover, volcanic ash, dust, and clouds of various types. In this study, the focus is on classifying cumulus clouds of various types (e.g., "fair weather, "towering, and newly glaciated cumulus, in addition to cumulonimbus). The SDLAC algorithm is demonstrated by showing examples using Geostationary Operational Environmental Satellite (GOES) 12, Meteosat Second Generation's (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI), and the Moderate Resolution Infrared Spectrometer (MODIS). Results indicate that the method performs well, classifying cumulus similarly between MODIS, SEVIRI, and GOES, despite the obvious channel and resolution differences between these three sensors. The SDLAC methodology has been used in several research activities related to convective weather forecasting, which offers some proof of concept for its value.


The concept of ethics as a set of guiding principles is becoming more and more important in the current healthcare setting. There are always problems in perception of what is right and what is wrong. According to Grogar-Murray and DiCroce ethics is that branch of philosophy that examines ideal human behaviour. Ethics are moral guidelines used to justify healthcare practices to promote quality of life. Ethics will be viewed from a conceptual framework of an ethical professional or legal environment with the need to understand the ethics in the past measuring ethics in the present and determining (if needed) how to create an appropriate ethical climate and code of professional conduct for the future. This article focuses on the Hippocratic oath medical ethical issues - in particular genetics - mistakes in medicine ethical principles and the political arena. (excerpt)


In this paper, a biologically-informed computational framework is developed to model the efficacy and to optimize the implementation of an implantable epi-retinal prosthesis that performs optogenetic stimulation through a μLED array. The developed model is capable of translating visual stimulus inputs into corresponding signals evoked in the transfected retinal cells through optogenetic stimulation, calculating the subsequent neuronal activities of the following retinal layers, and estimating the resulted brain's visual perception. As such, it can model and quantitatively analyze the impact of optical stimulation parameters (intensity, frequency, directivity, wavelength, etc.) and the μLED array's physical specifications (array size, density, pitch, implantation location, etc.) on the efficacy of the stimulation. Using this model, we compared optical and electrical stimulations in terms of the structural similarity between their induced visual perception in the brain and the visual stimulus input. We showed that thanks to the cell-type specificity of optogenetic stimulation, it can induce more relevant visual perception qualities than electrical stimulation. We also showed that its resulted visual perception substantially improves with scaling the stimulator's array size. The model was also used to qualitatively and quantitatively analyze the impact of parameters such as implantation location, light intensity, single- and dual-wavelength stimulation, and illumination divergence angle on the quality of the optical-stimulation-induced visual perception. In each case, the simulation results were followed by our interpretation from a biological point of view. More importantly, in each case, we discussed how the results could be used for optimizing different parameters of an implantable optogenetic stimulator to achieve maximum efficacy and energy efficiency. Keywords: Retinal prosthesis, optogenetics, visual perception, optical stimulation, μLED array, computational model, spatial resolution, pathway-specific stimulation.


Abstract Results from a systematic grinding study with the SM-320 Szego Mill are reported. A wide range of flow rates, from 750 to 5300 kg/h of coal, at 60–65% solids concentration has been covered, with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured. Data, including those for energy consumption, have been correlated in terms of the mass fraction of particles passing various mesh sizes 45 μm and up. A dynamic wet-grinding model recently developed for the Szego Mill is reviewed. Use of this model allows a priori predictions of limiting performance for all design and operating variables in the "paste grinding" regime, i.e., at relatively high solids concentrations which are optimal for wet grinding in the Szego Mill. Limiting size predictions for the SM-320 mill and the conditions used are presented along with an initial attempt to incorporate the breakage function in the model. Predictions confirm the observed effects of feed rate and ...


In a comparative anatomy laboratory study, two cats out of 16 were found to have an anomalous condition involving the presence of an accessory gall bladder. These two cases confirm earlier observations by Boyden ('26), where an extensive comparative study of the morphology and embryology of anomalous gall bladder conditions was pursued in cats, calves, sheep and lambs, pigs, and man, as well as a later report of a similar occurrence in a cat by Bartlett ('51). Moreover, one of the cats described in this report exhibits what may be a condition as yet not reported observed, namely, a quadruple gall bladder.


The maintenance of uniformity in food grade among the market available edible elements is quite debatable now-a-days. This ambiguity is mere consequence of versatility in the product vendors and various materials used for manufacturing the same. One of the important factors which governs the processed food's standard is its shelf life with and without refrigeration. It's a known fact that the food becomes a house for production of yeast, mold, bacteria and many other parasites on an extended shelf life. This process will route a way for aerobic and anaerobic culture in the food, for which the dominant end product would be methane (CH4). The proposed work aims at providing an amicable and affordable IoT device which is capable of identifying the extent of food spoilage and decides the degree of edibility based upon methane dissipation. The designed product additionally also features the measurement of humidity and temperature to ensure annunciation of food decay.


Dr. Kirsty Hudson, Cardiff University Professor Hazel Kemshall, De Montfort University Dr. Kieran McCartan, University of the West of England A limited public disclosure scheme has now been rolled out across all police forces in England and Wales, and in Scotland in the UK. These schemes operate quite differently to many of the schemes in the USA. Crucially, they all rely on a concerned adult making an enquiry,via the local police in the case of England and Wales, and through Stop It Now in Scotland (see: http://www.stopitnow.org.uk/scotland.htm), about a specific person and in relation to a specific child. There are no plans, as of writing, to develop and/or roll out a pilot study in Northern Ireland.


Stress corrosion cracking occurs if the three parameters -- material condition, tensile stress and water chemistry -- are in a critical range. In this study the material conditions especially of Ti- and Nb-stabilized steels are considered. The purpose of this work is to show the influence of the degree of sensitization of Ti- and Nb-stabilized stainless steels on stress corrosion cracking susceptibility in BWR water chemistry. This is an on-going research program. Preliminary results will be presented. Different types of stabilized, and for comparison unstabilized, stainless steels are examined in various heat treatment conditions with regard to their sensitization behavior by EPR tests (double loop) and TEM. The results are plotted in sensitization diagrams. The sensitization behavior depends on many parameters such as carbon content, stabilization element, stabilization ratio and materials history, e.g. solution heat treatment or cold working. The obtained EPR sensitization diagrams are compared with the well known sensitization diagrams from the literature, which were determined by standard IC test according to e.g. German standard DIN 50914 (equivalent to ASTM A 262, Pract. E). Based on the obtained EPR sensitization diagrams material conditions for SSRT tests were selected. The EPR values (Ir/Ia x 100%) of the tested Ti-stabilizedmore » stainless steel are in the range of {approx} 0.1--20%. The SSRT tests are carried out in high-temperature water with 0.4 ppm O{sub 2}, a conductivity of 0.5 {micro}S/cm and a strain rate of 1{times}10{sup {minus}6}{sup {minus}1}. The test temperature is 280 C. Ti-stabilized stainless steel with Ir/Ia x 100% > 1% suffered intergranular stress corrosion cracking under these conditions. The SCC tests for Nb-stabilized stainless steel are still in progress. The correlation between EPR value, chromium depletion and SSRT result will be shown for a selected material condition of sensitized Ti-stabilized stainless steel.« less


The anterior cruciate ligament is one of the most important ligaments in the knee joint (ACL). The ACL is necessary for appropriate knee joint mobility and mechanics. When the ACL is torn, patients may experience issues with their knee's function, as well as instability and the sensation of 'falling away' while walking. The anterior cruciate ligament acts as a main restraint on tibia-to-femur translation (anterior shear). Depending on the angle of knee flexion, this function is allocated to either anteromedial or posterolateral bundle. When the knee is fully extended, the posterolateral bundle is tense; however, when the knee flexes, the posterolateral bundle loosens and the anteromedial bundle tightens.
We report the case of a 32-year-old man who twisted his leg while jogging, resulting in a partial thickness ACL rupture and mild joint effusion along the periarticular surface of the right knee, as revealed by radiological symptoms and MRI.Conservative rehabilitation in a patient aged 32 year shows good results and so the surgery was not performed. Initially 10 weeks protocol was managed in hospital under the guidance of a therapist including strengthening, stretching and conditioning of lower limb muscles, later on as pain reduced and patient achieved functional pain free range 12 week protocol was further set for home program.

The South African higher education learning community is dominated by underprepared learners with different cultural backgrounds. With such diversity in the learning environment, the concept of same-time/same-place learning does not accommodate all the learning perception. The learning is fixed with formal context and in return lead to lack of access to the learning content and social resources for underprepared learners. On the other hand more and more learners are entering higher learning institutions with a reasonable acquiesce of Social Network Sites (SNS) and new technology innovation. This study took advantage of this phenomenon and simulated online classroom using FACEBOOK (FB) for a group of 1 st year learners registered for National Diploma at the Tshwane University of Technology (TUT) under the Information and Communication Technology (ICT) faculty. The aim is to explore the possibilities of formally adopting SNS as a tool for learning support in South African Institutions of higher learning. We heavily scrutinised the social presence and context-awareness theories on to uncover how FB could supplement learning outside classroom. Following a qualitative approach, a case study was employed to amass qualitative data in multiple conducts. One-on-One interviews were conducted with a sample of learners enrolled on the simulated social network classroom. Learning related interactions amongst learners in a form of text-cues were also collected as a secondary data and subjected to analysis to confirm experience, attitude and behaviour that research participants claim in the interview outcomes. Through content analysis we constructed the meaning of data (recorded communication) in the interview and text cues transcripts from online class using social presence and context awareness indicators. In this paper, we argue that SNS can provide supplementary learning support to learners regardless of time and space. Learners are able to converse using any language at any given time and space, including their home language, English or even informal spoken language when interrogating the learning content. This allows each learner an opportunity to participate in the interaction and indicates a higher sense of social presence.


Little is known about the hemodynamic response to exercise in the early development of essential hypertension(EH). Graded, supine bicycle exercise was performed in 13 children with EH (14.6±0.7 yr) and 13 normotensives(N) (12.3±1.8 yr). All children were taken to maximum voluntary exercise(PEAK). Left ventricular function was monitored echocardiographically by measurements of the left ventricular shortening fraction(LVSF). The responses to peak exercise in the two groups are shown below.These results show that young people with EH compared to N have a greater increase in systolic BP in response to peak exercise, and children with EH have significantly lower LVSF at rest. There is no difference of LVSF at peak exercise between EH and N showing that early EH does not impair the left ventricular response to the increased demands imposed by exercise. The reduced LVSF at rest is somewhat surprising and may indicate an early deleterious effect of essential hypertension on the heart which has not been recognized previously.


Around 24 million of people worldwide have some kind of dementia, and most of them are diagnosed to suffer from Alzheimer's disease (AD). In fact, every seven second a new case of dementia is identified, arriving to the rate of 4,6 new million cases per year. It is expected that by 2040 over 80 million of people will be affected. Neurological diseases are therefore a major public health problem due to the rise in the aging population, only in Europe these disorders cover approximately 35% of the burden of all diseases. In economical terms, brain diseases in Europe cost a total of 386 billion of euros per year, with an average of 829€ per inhabitant. AD and other dementias represent the second-leading cause of brain disorders after affective ones and equal with addiction diseases (Wittchen and Jacobi, 2005). Altogether dementias, and in particular AD represent a huge socio-economical impact, not only regarding the cost from the pharmacological point of view but also familiar cares which increase in an alarming rate in the last stages of the disease. Worthy to mention is the role of the family during the progression of this kind of diseases, relatives have to watch the patient every moment above all during the first lapses of memory and some of them need psychological help to assume the situation and the change in their lifestyle. The incidence and prevalence of this group of diseases explain the need to understand mechanisms underlying dementia to uncover early and discriminative diagnostic markers as well as new therapeutic targets in order to improve the quality of life of these patients and the efficacy of the treatements. For these reasons research in AD is currently considered as a priority. At this time, the pharmacological treatments available aim to enhance the cognitive impairments once the disease is diagnosed, only cholinesterase inhibitors and one NMDA receptor antagonist are commercialized. Despite these products can alleviate the symptomatology, they are far away to constitute an effective remedy to cure or prevent the deleterious effect of the disease. In line of these observations, methods for improving diagnosis are needed, the search of biomarkers and neuroimaging techniques might help to support clinical diagnosis and detect the disease in the earliest stages. The identification of potential genetic and environmental risk factors as well as protective ones may provide a new window of action even if interventions at this level are more complex and controversial (Ballard C et al., 2011).


Thirteen markers in Aspergillus amstelodami were mapped through meiotic and mitotic recombination, resulting in good correlation of the two linkage groups established by each method. Mapping via mitotic analysis proved the more efficient of the methods because of the long distances between some of the markers established in this organism. Visual selection of haploid segregants from mitotic recombination was aided by the ability to recover conidia which differed in colour from the haploid parents. These contained pairs of conidial colour markers which were not epistatic to each other.


The soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) continues to be the most damaging soybean pest [Glycine max (L.) Merr.] in the USA. A major gene that provides partial resistance to SCN is rhg1, which is located on linkage group (LG) G. The objectives of this study were to test the effect of rhg1 on SCN reproduction in both the field and greenhouse and on agronomic traits in the field. Two populations of near isogenic lines (NILs) that segregated for rhg1 were developed to test the effect of the gene. These NIL populations were tested for their ability to support SCN cyst development in a thermo-regulated water bath in a greenhouse and egg production estimated from soil samples taken from each plot in field tests. The NIL populations were evaluated for agronomic traits in field plots to determine the associated effects of rhg1 on these traits. In the greenhouse, NILs predicted to be carrying the resistance allele for rhg1 on the basis of a linked marker supported significantly (P 500 SCN eggs (100 cm 3 soil) -1 ]. These results show that resistance at rhg1 can have a large effect on SCN reproduction and may result in a significant yield increase.


ABSTRACT Measurement of single droplet drying in the acoustic levitator has been used to detect a correlation between the kinetics of aggregation and inactivation of the model protein l-glutamate dehydrogenase (GDH) during drying and particle formation. The droplet drying was performed at one set of conditions: drying gas temperature = 60°C; drying gas relative humidity = 1%, and drying gas velocity = 0.5 L/min. A centrifugation technique was used to remove insoluble aggregates from the rehydrated microparticles removed from the levitator chamber. Size exclusion chromatography could then be used to quantify the contents of nonaggregated native protein. During the constant-rate drying period up to the critical point of drying, there was retention of nonaggregated native structure. Only after the critical point of drying has been reached, a rapid decline in nonaggregated native content was observed owing to formation of insoluble aggregates. No sign of a soluble trimer of GDH was found. The kinetics of this behavior correlates closely with the kinetics of inactivation of the same enzyme in levitated microdroplets from the literature, i.e., retention of activity up to the critical point and rapid loss of activity after the critical point. The novelty of this work is that such a correlation between aggregation and inactivation can be detected during drying and particle formation on both sides of the critical point of drying.


Nowadays, ageing related diseases represent one of the most relevant challenges for developed countries. The use of healthcare remote technology may allow reducing most of the management of the chronic diseases meanwhile it may also contribute to the improvement of elderly people's quality of life. Unfortunately, despite the advent of Internet of things and the even decreasing price of sensors, current proposals are not extensible during runtime meaning that they need to be maintained offline by engineers. Therefore, in this paper we discuss how to build an ad-hoc extensible (during runtime) healthcare monitoring system by using low cost wireless sensors and already existent Internet of things technology as communication platform. Moreover, we present a prototype of a basic healthcare remote monitoring system, which alerts, in real time, patients' relatives or medical doctors that an elderly people is experienced a problem that could need medical attention or hospitalization.


Following recent trends and events – such as the global financial crisis along with environmental disasters, trust in business has lost so much and the investors and other stakeholders has been affected. Financial reporting has changes over the last years and is currently being challenged if it provides an accurate picture of the present and future performance of companies. Annual reports based on financial information cannot to provide sufficient information to potential investors in order to make a correct investment decision. A new concept has emerged in order to answer their challenge. This is integrating reporting and it offers the opportunity to provide investors strategy and value creation, how companies make decisions and if they should continue to be invested in the business or not. A integrated report go beyond the traditional financial metrics. The aim of this discussion paper is to describe this new concept and to give a literature review analysis of the framework regarding integrated reporting evolution from the non-financial reporting, through environmental stage, until now. Based on literature overview, this paper gives an explanation of the companies need to disclose in addition to financial information of the other information: non-financial, sustainability and corporate social responsibility. A good and very known example for the integrated reporting is Philips Electronics, the Dutch healthcare and lighting company, a pioneer that embrace this concept, and the paper make an analysis of its experience. In 2008, company Philips decided to publish an integrated financial social and environmental report which reflecting the progress and embedding sustainability in way of doing business. This is also supported by the inclusion of sustainability in the Philips Mission, Vision and the company strategy. This is seventh annual integrated financial, social and environmental report which has been prepared in line with the International Integrated Reporting Council (IIRC) Integrated Reporting framework. Company Philips is a frontrunner in this field, because publishes annual report with the highest (reasonable) assurance level on the financial, social and environmental performance.


IntroductionAlthough not formally recognized by the Judicial Conference of the United States, nearly half of federal district courts operate some form of problem-solving court. Citing the positive energy those courts have produced and studies conducted in various jurisdictions, advocates argue it is time for federal problem-solving courts to be formally recognized and expanded. On the other hand, opponents argue that empirical support for problem-solving courts is lacking. There have only been a handful of federal studies with results that have been mixed at best, and all the research efforts have been subject to methodological limitations. Their impact on recidivism aside, federal problem-solving courts face issues of scalability, including cost, in the federal system. Observers, however, are increasingly positive about problem-solving courts' work in the areas of mentorship and managing the collateral consequences of a criminal conviction. Possibly greater focus in those areas and better division of duties among other problem-solving court members can drive down costs, enhance outcomes, and even avoid potential ethical issues. However, it will take more time and effort to determine if those benefits can, in fact, be realized. That all comes at the cost of other promising programs and those we already know reduce recidivism. The criminal justice system, unfortunately, has a history of maintaining and expanding popular programs only to discover later that those programs are ineffective. Consequently, ongoing and meaningful assessment is vitally important.PROBLEM-SOLVING COURTS ARE designed to promote public safety and stabilize communities. As part of the court program, judges work collaboratively with litigants and others to resolve personal and social problems presented by "justice-involved people."2 By addressing those problems, courts mitigate factors, such as substance abuse,3 that are often associated with crime and recidivism.4There are now thousands of problem- solving courts operating in state and local jurisdictions (Marlowe, Hardin, & Fox, 2016), and nearly half of federal district courts have programs as well (Meierhoefer & Breen, 2013). In the federal system, the programs are adopted at the discretion of interested districts, and they rely on decentralized funding allotments and volunteers for support. The Federal Judicial Center provides training for problem-solving courts (Sherman, Taxman, & Robinson, 2011), but the courts have not been formally recognized by the Judicial Conference of the United States,5 and there are no judiciary-wide policies governing their operation. For those and other reasons, there is significant variability in and among federal problem-solving courts and they handle only a small number of cases each year (Meierhoefer & Breen, 2013).6Advocates argue that the federal problem-solving courts have proven themselves effective and efficient, and should be formally recognized and expanded (Marlowe, Hardin, & Fox, 2016; Berman & Feinblatt, 2015).7 Opponents, on the other hand, assert that it is not clear that problem-solving courts have met their primary goal of lowering recidivism while reducing social and economic costs. Moreover, the courts bring with them a variety of ethical, policy, and practical questions. Underscoring all these concerns is the criminal justice systems history of sustaining and expanding programs that seem promising but later prove to be ineffective and costly.Possibly unique to the federal context, there is also concern that problem-solving courts are inconsistent with the judiciary's long-standing position against specialized courts and the direct assignment of cases to judges.8 Further working against expansion of problem-solving courts in the federal system is the sheer size and diversity of the system itself.9This article seeks to assist in answering the question whether federal problem-solving courts should be expanded. …


Fault detection efficiency at careful source code reading (that is, code review) is significantly different between reviewers. In this paper, authors investigate the effect of review procedure instruction which formed from effective reviewers' reading process to reviewers. Our instruction for the reviewer consists of three steps, 1) read design specification at the initial phase of review, 2) read the entire source codes to understand structure of the program, and 3) verify the consistency between the design specifications and the source code. In the experiment, authors divide subjects into two groups and instruct the above steps to a group and compare the fault detection efficiency. The result of the experiment shows that the group with the instruction significantly improved their fault detection ratio.

Abstract The Dingle Peninsula exposes the most complete Old Red Sandstone (ORS) succession in Ireland, ranging from Late Silurian to Early Carboniferous in age. It lies within 20 km of several ENE-WSW aligned lineaments, including the Dingle Bay Lineament immediately to the south, and the putative trace of the Iapetus Suture to the north. These were formed in a regime of sinistral transpression in the Late Silurian to Early Devonian. It also forms part of the northern margin of the Munster Basin formed by Late Devonian N-S extension. The sequence is divided into five groups: the Dingle Group, the Caherbla Group, the Smerwick Group, the Pointagare Group and the Glengarriff Harbour Group in ascending order. The Dingle Group records initially lacustrine dominated sedimentation followed by deposition in laterally and axially draining fluvial systems within the NE-SW aligned Dingle basin. Generation and inversion of the Dingle basin, and subsequent deposition of the Caherbla Group — composed of alluvial fan and aeolian dunefield deposits — may be related to sinistral strike-slip displacements along the Dingle Bay Lineament. The Smerwick and Pointagare Groups, also consisting of fluvial and aeolian facies, are interpreted to have been deposited in small half grabens restricted to the north of the peninsula. Further Late Devonian extension and subsidence allowed the more widespread deposition of the Glengarriff Harbour Group comprising braided river sediments. Thus the lower part of the ORS of the Dingle Peninsula is interpreted to reflect the Late Silurian to Early Devonian development of localised basins adjacent to sinistral strike-slip faults that were active during the final oblique convergence within the British and Irish Caledonides. In the later Devonian these lineaments were reactivated as normal faults during N-S extension to form the northern margin of the more extensive Munster basin. This change in tectonic regime is also reflected in the swing of major fluvial drainage from an early NE-SW along-basin alignment to a later southerly directed paleoflow.

This paper provides the outcome of a preliminary research, which investigates the consumers' behaviour and attitudes towards private-label evaporated milk. Research methodology is twofold, including qualitative and quantitative research. Results indicate that few respondents purchase private label milk. The main reasons for not purchasing are the perception that it is inferior in quality compared to the manufacturers' brand, routine purchase, and consumers' reluctance to "risk" changing brands, while price is the main reason for purchase. Results are discussed for retailing stores selling private label evaporated milk, as well as marketing strategies in order to increase the consumers' response towards the product.


Spatiomolecular mapping of hippocampal dopamine receptor D2 (D2R) neurons revealed that in addition to hilar mossy cells, hippocampal SST-INs and, to a lesser extent, PV-INs expressed D2R. However, while the role of D2R signaling onto mossy cells has been characterized, the consequence of D2R activation onto hippocampal SST-INs and PV-INs is unknown. By combining pharmacological approaches and patch-clamp recordings in organotypic hippocampal slices from control or mice lacking Drd2 selectively in SST-INs and PV-INs, we found that D2R activation increase excitability in SST-INs while it decreases in PV-INs. These D2R-mediated changes rely on distinct intracellular pathways, involving the non-canonical β- arrestin-dependent pathway in SST-INs and the G protein-dependent pathway in PV-INs. Finally, our study also unveiled that D2R activation modulates theta oscillations through SST- INs D2R signaling.


One of the major factors of the contemporary social world is industrialization. Recent industrial developments have moved in two major directions. First, there has been a tremendous increase in technological innovation, reaching the stage which we call automation. The machines which we have developed are doing their work only too well, including some tasks which we had long though could be done only by human hands and heads. Not only the blue-collar worker but also the white-collar worker seems to be faced with the possibility of technological unemployment. [excerpt]

Image deblurring by a deconvolution method requires accurate knowledge of the blur kernel. Existing point spread function (PSF) models in the literature corresponding to lens aberrations and defocus are either parameterized and spatially invariant or spatially varying but discretely defined. In this paper, a parameterized model is developed and presented for a PSF which is spatially varying due to lens aberrations and defocus in an imaging system. The model is established from the Seidel third-order aberration coefficient and the Hu moment. A skew normal Gauss model is selected for parameterized PSF geometry structure. The accuracy of the model is demonstrated with simulations and measurements for a defocused infrared camera and a single spherical lens digital camera. Compared with optical software Code V, the visual results of two optical systems validate our analysis and proposed method in size, shape and direction. Quantitative evaluation results reveal the excellent accuracy of the blur kernel model.


In this study, fifty samples from nodules of skin tissue collected from cattle were clinically supposed to be infected with lumpy skin disease (LSD) from deferent area in Al-Qadisiyah province .These specimens were provided to PCR assay. The endpoint of conventional PCR assay was sent to sequence analysis. The results revealed that thirty-nine samples out of fifty were positive to lumpy skin disease virus at 752bp PCR product of p32 gene, the sequence analysis of five positive samples were done as a confirmative diagnosis to PCR assay. The sequences of these five samples can be found under the accession numbers (KR066462.1,KR066463.1,KR066464.1,KR066465.1 and KR066466.1) at NCBI-Gen Bank submission. In conclusion; the sequence analysis of five local isolate of lumpy skin disease virus was close related to NCBI-Blast reference lumpy skin disease virus isolate (KU720359.1) and Kurdistan isolates, whereas others "Turkish and Egyptian isolates" were different.


Molecular systematic methods have been applied to all levels of problem in the diatoms. A possible sister group to the diatoms has been identified, the primary evolutionary radiation has been shown to be among centric diatom lineages, and the systematic positions of some problematic genera have been established. Certain structural characteristics previously used to diagnose higher taxa have been shown to exhibit homoplasy, and examination of selected complexes of diatoms has shown that cryptic and semicryptic species are probably widespread. Population genetics show that some species are panmictic over large geographical areas, while others are strongly differentiated at the population level, either geographically or temporally. Ongoing research addresses the major biogeographical question of whether diatom species are ubiquitous. On the negative side, most gene trees are disappointing because of the low statistical support for basal nodes in group-wide analyses; independent data sources (cytology, fossils) also mostly fail to discriminate between competing hypotheses of relationships. Constraints on progress include the relative poverty of culture collections and lack of multi-gene sequence data. The worst problem is the poor state of "diatomics" (holistic information about diatom species): for most diatoms, low-grade information about cell wall morphology is all that is available. Improved phylogenies are therefore often unedifying.

The use of modern materials and specialized forming techniques have enabled the ISR Division at CERN to produce very transparent interaction area vacuum chambers. The design and fabrication methods used to conceive and form these chambers are described. Special reference is made to the titanium chamber in intersection 7, the inconel chamber in intersection 8, and the stainless steel chamber in intersection 4. A method is given for rationalising the choice of material for interaction area vacuum chambers for any colliding beam machine.


Significance The CD8+ T cell response is crucial in protecting the organism against infections and cancer. This protective response relies on the production of effector molecules and the generation of long-lived memory cells. Understanding the processes governing CD8+ T cell responses is essential for the development of better vaccine strategies and immune cell therapies. Here, we show that deletion of the transcription factor NR4A3 leads to increased memory generation and effector functions. This results from an early impact on the CD8+ T cell transcriptional memory program and on chromatin accessibility for bZIP transcription factors. Thus, we identify NR4A3 as a key regulator of CD8+ T cell function and differentiation, which could have therapeutic implications. Enhancing long-term persistence while simultaneously potentiating the effector response of CD8+ T cells has been a long-standing goal in immunology to produce better vaccines and adoptive cell therapy products. NR4A3 is a transcription factor of the orphan nuclear receptor family. While it is rapidly and transiently expressed following T cell activation, its role in the early stages of T cell response is unknown. We show that NR4A3-deficient murine CD8+ T cells differentiate preferentially into memory precursor and central memory cells, but also produce more cytokines. This is explained by an early influence of NR4A3 deficiency on the memory transcriptional program and on accessibility of chromatin regions with motifs for bZIP transcription factors, which impacts the transcription of Fos/Jun target genes. Our results reveal a unique and early role for NR4A3 in programming CD8+ T cell differentiation and function. Manipulating NR4A3 activity may represent a promising strategy to improve vaccination and T cell therapy.


ABSTRACT This study assesses the use of various technologies, from institutional virtual learning environments to Web 2.0 tools, amongst learners studying at six general Further Education colleges in the UK. The study surveyed 218 students from a range of disciplines and qualifications. Cluster analysis revealed distinct patterns of engagement with technologies in both personal/social and educational contexts. Some support was found for a connection between personal/social and academic uses of technology. In contrast to the dominant narrative of learners as digitally fluent technology users, the analysis showed the majority of learners were using educational technologies in fairly simplistic ways that satisfy the demands of their course. Significant relationships were found between digital practices in college and subject studied and gender. The discussion draws on the literature of digital literacy practices in order to interpret the findings and inform the planning and development of learning technologies.

Amyloid ? (A?) is the major component of the senile plaques in Alzheimer's disease (AD). The mechanism underlying cell death in AD includes oxidative stress, apoptosis, impaired mitochondrial function and receptor mediated effects. Compounds that specifically bind to A? are neuroprotective. Catalase is an antioxidant enzyme that specifically binds A?. Kisspeptin (KP) is a product of the KiSS-1 gene and contains an A? binding domain, which also interacts with A?. The localization of catalase, KP and A? in the AD brain plus the effects of catalase and KiSS-1 overexpression in neuronal cells were investigated in the present study.
Tissue sections from the AD pons region were immunohistochemically stained to determine if catalase or KP colocalized with A? deposits. The immunohistochemistry results show that immunoreactive KP or immunoreactive catalase co-localizes with immunoreactive A? in AD pons sections. These results suggest that endogenous catalase and KP could play neuroprotective roles in AD.
Catalase and KiSS-1 overexpressing gene models were created by stably transfecting human catalase and KiSS-1 constructs into SH-SY5Y cells and overexpression confirmed by RT-PCR, immunocytochemistry and Western blotting. The effects of A? and H2O2 on cell viability were determined by either MTT (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) or trypan blue assay.
Catalase overexpressing SH-SY5Y neurons showed a reduced susceptibility to A? and H2O2 toxicity compared to vector control cells. The catalase overexpression neuroprotection could by reduced by the catalase activity inhibitor 3-Amino-1,2,4-triazole and an inhibitor of catalase-A? interactions benzothiazole aniline-tetra (ethylene glycol).
The KiSS-1 overexpressing SH-SY5Y neurons also showed a reduced susceptibility to A? and H2O2 toxicity compared to vector control cells. The KiSS-1 overexpression neuroprotection could by reduced by an anti-KP antibody, the oyxtocin antagonist atosiban and the cyclooxygenase inhibitor SC-560.
In conclusion, both catalase and KP colocalize with A? in AD pons sections and overexpression of catalase or KiSS-1 is neuroprotective against A? toxicity.


The History of Hispanic-American Lexicography The present text is a summary of the history of Hispanic-American lexicography – an area of Spanish lexicography that is relatively rarely discussed in general lexicographic studies. As this topic is quite broad, the article opens with a discussion of the Hispanic-Amerindian lexicography in the colonial period from the first works to the independence stage. Then the main achievements of contemporary Hispanic-American lexicography are presented. At the end, a paragraph is dedicated to the challenges of the metalexicography in Spanish-speaking America. For a better understanding, the main text is preceded with a brief historical-cultural outline. StudiaIberystyczne_19.indb 223 2021-04-22 15:44:47


Irradiation of a solution of 1,3,5-tricyanobenzene in acetonitrile in the presence of toluene gives 1-benzyl-3,5-dicyanobenzene and 1-benzyl-3,5,6-tricyanobenzene. In a toluene solution only bibenzyl is obtained. On the basis of results obtained using [2H8]toluene (i.e. deuterium incorporation only in the benzyl and not in the cyanoaromatic moiety) a series of reactions which involves photoinduced electron-transfer, removal of proton from the radical cation, and then coupling of the radical anion and the radical formed is postulated. It is also suggested that for the coupling reaction to take place then the reduction potential for radical anion to dianion on the cyanoaromatic species might play an important role.


We have investigated the width dependence of Sb delta (δ) doping layers grown by Si solid phase epitaxy (SPE) on the Sb surface reconstruction prior to Si deposition. Depending on the Sb adsorption conditions a 2×1 and a 2×n surface reconstruction is observed. Measurements of crystal truncation rods and x‐ray standing waves show a drastically reduced interface roughness and a better crystal quality for δ layers grown on Sb:Si(001)−2×n substrates in comparison to Sb:Si(001)‐2×1, which we attribute to reduced surface stress of the Sb:Si(001)‐2×n reconstruction.


Objective: To compare the effectiveness of 70-mg and 200-mg doses of IV erythromycin in improving gastric emptying in critically ill patients. Design: Gastric emptying was measured on consecutive days; day 1 (pretreatment), day 2 (posttreatment) after an IV infusion of either 70 or 200 mg erythromycin or saline placebo (0.9%), in a randomized double-blind fashion. Setting: Mixed medical/surgical intensive care unit, tertiary referral. Patients and Participants: Thirty-five randomly selected, mechanically ventilated, enterally fed critically ill patients (median APACHE II score 19 on admission). Interventions: On day 2, either 70 or 200 mg erythromycin or saline was administered IV over 20 min. Measurements and Results: Gastric emptying was measured using the [13C]octanoic acid breath test. The gastric emptying coefficient (GEC) and half-emptying time (t½) were calculated from the area under the 13CO2-recovery curve. Pretreatment gastric emptying measurements were similar in all 3 patient groups. Treatment...


A lagged adaptive adjustment mechanism has been developed to stabilize a high-order discrete system. Theoretical proofs and computer simulations have been provided to show the effectiveness and efficiency of this new mechanism in practice. The mechanism ensures that the adjusted system converges to its generic fixed points and achieves the convergence with a high speed. Besides, it requires neither a priori information about the system itself nor any external generated control signal.


Spectroscopic calculations for 38 tetrahedral XY/sub 4/ molecules were performed, assuming small harmonic vibrations. The results of following quantities are reported: force constants, compliance constarts, mean-square amplitude matrices, parailel and perpendicular mean-square amplitudes, mean amplitudes of vibration, and BastiansenMorino's shrinkage effects. One arithmetic error in previous work on this molecular model is corrected. (auth)


BACKGROUND Deakin University graduated its first cohort of Civil Engineering graduates in 2012. In the continually changing professional and university learning and teaching environments of engineering education, it is important to establish the link between learning approaches adopted by the students and their perceptions of the learning environment (particularly the teaching quality) at the university. Literature studies suggest that the learning outcomes can be achieved more efficiently when the students' perceptions of learning environment match with their learning approaches. Although there exists significant amount of literature regarding the Course Experience Surveys, this study is aimed at going into detail by re-designing survey questionnaire and analysing student responses to establish these interactions. Further strategies to improve the university learning environment can be developed taking into account the students' learning approaches at both unit/subject and course/program levels.


Visible light responsive nitrogen-doped titania nanocrystals were prepared by "Homogeneous Precipitation-Solvothermal Process" in TiCl3-hexamethylenetetramine (C6Hi2N4) mixed solution. The phase composition, crystallinity, microstructure and specific surface area of titania greatly changed depending on pH,solvent and temperature. The titania powders prepared in TiCl3-hexamethylenetetramine aqueous solutions at pH 1~6 and 190℃ for 2 h consisted of single phase of brookite and that prepared at pH 9 was single phase of rutile. On the other hand, the sample prepared in the presence of methanol at pH 9 consisted of single phase of anatase. All titania powders prepared in the present study were yellow and showed excellent visible light absorption property and photocatalytic ability for NO destruction under irradiation of the visible light (λ>510nm). The photocatalytic activity of the sample possessing similar specific surface area was in the order anatase > brookite > rutile. The photocatalytic activity of nitrogen doped titania under irradiation of visible light (λ>510 nm) slightly decreased with increasing calcination temperature up to 600℃ and then greatly decreased at 800 C. The visible light responsive photocatalytic activity of rutile titania nanoparticles could be improved by forming nanocomposite with layered tetratitanate possessing high specific surface area via a delamination-reassembly process of K2Ti4O9 combined with planetary ball-milling.


In 20 untreated patients with CML in the chronic phase the proportion of erythro-blasts was found to be higher in aspirates from the spleen than in bone marrow smears. The mitotic indices of the erythroblasts were significantly lower, and megalo-blastic changes more common, in the spleen than in the bone marrow. Although the erythroblasts constitute a considerable proportion of the haemopoietic tissue of the spleen in CML, the relatively low mitotic activity and the megaloblastic changes may indicate an ineffective red cell production in this organ.


Although competitive balance is an important concept for professional team sports, its quantification still remains an issue. The main objective of this study is to identify the best or optimal index for the study of competitive balance in European football using a number of economic variables and data from eight domestic leagues from 1959 to 2008. The findings that refer to the indices specially designed to capture the complex structure of European football support the longstanding Uncertainty of Outcome Hypothesis. The most comprehensive bi-dimensional Special Dynamic Concentration index has the greatest effect on attendance while ranking mobility across seasons is more important for fans than seasonal performance.


OBJECTIVE
To understand the infection status and main risk factors of soil-transmitted nematodes in southwest China so as to provide the evidence for making the control programs for soil-transmitted nematodiasis.

METHODS
The prevalence of soil-transmitted nematode infections was determined by Kato-Katz technique and influencing factors were surveyed by using a standardized questionnaire, and in part of the children, the examination of Enterobius vermicularis eggs was performed by using the cellophane swab method. The relationship between soil-transmitted nematode infections and influencing factors was analyzed by the multiple probit estimated method.

RESULTS
A total of 1 707 children were examined, with a soil-transmitted nematode infection rate of 22.2%, the crowd infection rates ofAscaris lumbricoides, hookworm, and Trichuris trichiura were 16.0%, 3.8% and 6.6% respectively and 495 children were examined on Enterobius vermicularis eggs, with the infection rate of 5.1%. The results of probit estimated analysis suggested that the effects of 4 factors on soil-transmitted nematode infections were significant (all P values were less than 0.05), namely the number of sib, educational level of mother, drinking unboiled water and raising livestock and poultry. Among the factors above, the educational level of mother could reduce the probability of infection (ME = -0.074), while the number of sib, drinking unboiled water and raising livestock and poultry could increase the probability of the infections (with ME of 0.028, -0.112 and 0.080, respectively).

CONCLUSIONS
Soil-transmitted nematode infection rates are still in a high level for children in southwest poor areas of China, with Ascaris lumbricoides as a priority. The changes of children's bad health habits, raising livestock and poultry habits, and implementing the health education about parasitic diseases in mothers would be of great significance for the prevention and control of soil-transmitted nematodiasis.


In the year since the Genesis solar wind collector fragments were returned, early science samples, specimens for cleaning experiments, and science allocations have been distributed. Solar wind samples are stored under nitrogen and handled in an ISO Class 4 (Class 10) laboratory. For array collector fragments, a basic characterization process has been established. This characterization consists of identification of solar wind regime, whole fragment image for identification and surface quality, higher magnification images for contaminant particle density, and assessment of molecular film contaminant thickness via ellipsometry modeling. Compilations of this characterization data for AuOS (gold film on sapphire), and sapphire from the bulk solar wind for fragments greater than 2 cm are available. Removal of contaminant particles using flowing ultrapure water (UPW) energized megasonically is provided as requested.


Regularities of photosynthetic pigments accumulation (chlorophylls, carotenoids, and flavonoid compounds) in plants growing on the territory of the «Deep Sabun» base of the «Siberian Uvaly» Natural Park have been analyzed to evaluate the ecological and biochemical status of the most significant plant species.

Purpose: To investigate whether asiatic acid (AA) can improve the quantity and function of retinal ganglion cells (RGCs), as well as how AA regulates synaptic pathways in rat models with chronic glaucoma. Methods: In our study, a rat model of chronic glaucoma was prepared via the electrocoagulation of the episcleral veins. The numbers of surviving RGCs were counted via retrograde Fluorogold labeling, and a whole-cell patch clamp was used to clamp RGCs in normal retinal sections and in retinal sections 4 weeks after glaucoma induction. Results: Retrograde-Fluorogold-labeled RGC loss caused by persistent glaucoma was decreased by AA. Additionally, AA reduced the postsynaptic current produced by N-methyl-D-aspartate (NMDA) and diminished miniature glutamatergic excitatory neurotransmission to RGCs. On the other hand, AA increased miniature gamma-aminobutyric acid (GABA)-ergic inhibitory neurotransmission to RGCs and enhanced the GABA-induced postsynaptic current. The excitability of the RGC itself was also decreased by AA. RGCs in glaucomatous slices were less excitable because AA decreased their spontaneous action potential frequency and membrane potential, which led to a hyperpolarized condition. Conclusions: AA directly protected RGCs in a chronic glaucoma rat model by lowering their hyperexcitability. To enhance RGCs' survival and function in glaucoma, AA may be a viable therapeutic drug.

Aim: The present study evaluated the activity of Digesti'Vas on gastrointestinal motility, appetite and hepatoprotective effects in a rodent model. Methods: Digesti'Vas is a polyherbal formulation developed by Suguna Foods Pvt Ltd. Acute toxicity and gastrointestinal motility activity were evaluated in mice. Appetite activity and potential hepatoprotective effects were evaluated in rats. Results: Since Digesti' Vas did not exhibit acute toxicity when given orally up toa concentration of 2000 mg/kg bw, 200mg/kg body wt(1/10 th of 2000 mg/kg) was selected as the median dose. Digesti'Vas showed a significant increase in mean defecation period (346.2 ± 65.83min), comparable to the positive control, loperamide (383.0 ± 37.83min), in comparison to the normal control group (251.2 ± 60.32min). Digesti'Vas treatment also led to a significant increase in the percentage change in body weight (8.367±3.021 g) when compared to the normal control group (3.618±2.088g) and a significant increase in percentage change in food intake (13.28±3.673 g) when compared to the normal control group (8.657±2.160 g). When measurements were done on various liver parameters, it was found that Digesti'Vas treated animals showed a significant decrease in serum ALP levels (401.8±10.04U/L) compared to CCl 4 treated animals (493.2±108.4 U/L); comparable to the positive control, Silymarin (370.5±37.82 U/L). Digesti'Vas significantly decreased serum SGPT levels (57.03±66.01U/L), compared to CCl 4 treated animals (420.8±214.1 U/L); in agreement with levels seen in Silymarin treated animals (61.39±37.87 U/L).Furthermore, Digesti'Vas significantly decreased SGOT (6.953±3.712 U/L) levels compared to the CCl 4 treated group (29.65±5.765 U/L), in keeping with levels seen after treatment with Silymarin (10.71±6.135 U/L). Conclusion: This study suggests that Digesti'Vas, a herbal preparation that is formulated by Suguna Foods Pvt Ltd, possesses antimotility, hepatoprotective, and increased appetite effects in a rodent model. Future studies investing the role of Digesti'Vas in alleviating gastrointestinal disorders are certainly warranted.

Traditional analytics rely largely on search engine "similarity" scores (e.g. XCorr, ion-score, hyperscore) that quantify the degree of similarity between the measured spectrum and a predicted spectrum, the latter derived from a candidate peptide sequence using a sequence-to-spectrum ionization model. They evolved mainly for abundant peptides with robust spectral signals. Efforts to improve the search engine score, for example by incorporating accurate fragment data, have had limited success or worse. Some ad hoc efforts identify unexpectedly numerous peptides having near-identical mass, charge, and chromatographic retention time i.e. same isotopic envelopes at the same split-second in a multihour experiment better explained by faulty analytics.

Within the realm of multi-level systems, the European Union (EU) constitutes a unique case characterized by a compound executive order which might serve as a template for building similar systems worldwide. This chapter examines the literature on the EU executive. Theoretically inspired mainly by neo-institutionalism, this literature revolves around four basic themes: the institutional structure and the powers of the EU's executive(s); the performance of and the interactions among executive institutions; the exercise of political leadership; the democratic legitimacy and accountability of the executive(s). Despite ongoing research and debate, scholars agree that EU executive power is widely dispersed among various institutions and that their performance and interactions are characterized by cooperation and conflict. Furthermore, they see leadership in this context faced with limited opportunities and multiple constraints and the democratic legitimacy and accountability of EU executives as poorly developed. The chapter concludes that many research lacunae remain.


Background: The traditional ultracentrifugation purification method of hepatitis C virus (HCV) particles requires special equipment, limiting its wide application. Therefore, more effective and convenient methods for HCV are needed. Objectives: The present study aimed to establish simple and effective purification methods for HCV. Methods: The infectious clone of the HCV genome (JFH-1) was transfected to the human hepatoma cell line (Huh7.5.1) and cultured in Dulbecco's modified eagle medium/nutrient mixture F-12. The infectivity of JFH-1 culture was determined by reverse transcription-quantitative polymerase chain reaction and immunofluorescence. After concentration by centrifugal filter devices, HCV particles were purified by heparin-affinity chromatography and magnetic separation technique. The purified viruses were detected by the western blot and immune-electron microscopy. Results: The infectious titer of JFH-1 transfected Huh7.5.1 in the serum-free culture medium was 4.5 × 104 FFU/mL, and HCV ribonucleic acid load was 3.946 × 106 IU/mL in 30 days of cell culture post-transfection. After purification by heparin-affinity chromatography or magnetic separation method, viral particles were visualized with spherical morphology and an average diameter of 55 nm assessed by electron microscopy. The viruses were confirmed by the western blot and immune-electron microscopy with specific antibodies to HCV. Conclusions: The heparin-affinity chromatography and magnetic separation methods were established for the purification of HCV, which were simple and efficient methods for the stable purification of HCV particles on a large scale.


The relation between the solar wind speed (V) observed at the earth's distance and the latitudinal angular distance of the earth (λ) from the magnetic neutral line on the so-called "source surface" of the sun, which is determined from the spherical harmonic analysis of the line-of-sight component of the photospheric magnetic field [Hoeksema et al., 1982], is examined. It is shown that the solar wind speed V increases as |λ| increases and that V does not depend on the heliographic latitude of the earth. This relation may be represented by V(km/s) = 408 + 473sin²λ during the period between May 1976 and August 1977. The presence of such a latitudinal gradient of V indicates that some of the time variations of V observed at the earth are caused by the spatial variations of V with respect to λ.


COVID-19-related quarantine measures resulted in a significant increase of interest in online collaboration tools. This includes virtual reality (VR) or, in more general term, extended reality (XR) solutions. Shared XR allows for activities such as presentations, training of personnel or therapy to take place in a virtual space instead of a real one. To make online XR as accessible as possible, a significant effort has been put into the development of solutions that can run directly in web browsers. One of the most recognized solutions is the A-Frame software framework, created by Mozilla VR team and supporting most of the contemporary XR hardware. In addition, an extension called Networked-Aframe allows multiple users to share virtual environments, created using A-Frame, in real time. In this article, we introduce and experimentally evaluate three components that extend the functionality of A-Frame and Networked-Aframe. The first one extends Networked-Aframe with the ability to monitor and control users in a shared virtual scene. The second one implements six degrees of freedom motion tracking for smartphone-based VR headsets. The third one brings hand gesture support to the Microsoft HoloLens holographic computer. The evaluation was performed in a dedicated local network environment with 5, 10, 15 and 20 client computers. Each computer represented one user in a shared virtual scene. Since the experiments were carried out with and without the introduced components, the results presented here can also be regarded as a performance evaluation of A-Frame and Networked-Aframe themselves.


Mental disorders are increasingly becoming a significant issue among medical students, consequent to rapid societal changes and increase in life stress. Yet, help seeking for mental health problems in medical students is universally poor. Attitudinal factors, stigma, and systemic barriers prevent early detection of such problems and often push students to self-harm and suicide. The fear of losing the capacity and license to practice often prevents students to come forward for treatment. Here, we discuss the various issues of a similar case from India and deliberate on the possible solutions to help such students in need.


The integrated vehicle and crew scheduling problem is a difficult and widely studied Combinatorial Optimization problem. Several studies have shown that exact approaches for this problem are not useful in practical situations due to the high computational costs involved. This paper describes a hybrid genetic algorithm for vehicle and crew scheduling, which is modeled as a maximal covering problem with multiples resources. In addition, an innovative mathematical formulation is presented. Computational results with real vehicle and crew scheduling problem instances are presented and discussed. These results indicate that the proposed approach has a considerable potential for achieving significant gains in terms of operation costs and planning times.


Diabetes Mellitus is a metabolic disorder which may result in severe and potentially fatal complications if not well-treated and monitored. In this study, a quantitative analysis of the data collected using CGM (Continuous Glucose Monitoring) devices from eight subjects with type 2 diabetes in good metabolic control at the University Polyclinic Agostino Gemelli, Catholic University of the Sacred Heart, was carried out. In particular, a system of ordinary differential equations whose state variables are affected by a sequence of stochastic perturbations was proposed and used to extract more informative inferences from the patients' data. For this work, Matlab and R programs were used to find the most appropriate values of the parameters (according to the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC)) for each patient. Fitting was carried out by Particle Swarm Optimization to minimize the ordinary least squares error between the observed CGM data and the data from the ODE model. Goodness of fit tests were made in order to assess which probability distribution was best suitable for representing the waiting times computed from the model parameters. Finally, both parametric and non-parametric density estimation of the frequency histograms associated with the variability of the glucose elimination rate from blood were conducted and their representative parameters assessed from the data. The results show that the chosen models succeed in capturing most of the glucose fluctuations for almost every patient.


Admission seekers into Nigerian tertiary institutions of learning are currently supplied with a compact discthat contains among others,an electronic brochure which contains therequirements for being admitted into their preferred courses of study in PDF format. The brochure is also downloadable from the Joint Admissions and Matriculation Board's (JAMB) website. Searching through the compact disc requires a personal computer (PC), a tablet computer or a smartphone. However, these devicesare not widely accessible considering the populationof Nigerians that have access to them because of the cost implications of obtaining one. Consequently, there is a need to make it accessible via a platform that is widely accessible. Furthermore, even though the board provides a mobile app to access some of its services, admission requirements service is not inclusive.In this work, a multimodal admission requirements search system that enables access to the brochure's contents electronically, in both text and audio formats via PC and as well as mobile phones (including feature phones) was developed and evaluated for its acceptability and user satisfaction.The results obtained show that the system was widely accepted and the users were satisfied with the system. This means that if adopted, the system will be widely accepted and will engender cost-effectiveness.


Riserless drilling poses numerous operational challenges that adversely affect the efficiency of the drilling process. These challenges include increased torque and drag, buckling, increased vibration, poor hole cleaning, tubular failures, poor cement jobs, and associated problems during tripping operations. These challenges are closely associated with complex bottomhole assemblies (BHAs) and the vibration of the drillstring when the topholes are drilled directionally. Current methods lack proper modeling to predict drillstring vibration. This paper presents and validates a modified model to predict severe damaging vibrations, analysis techniques, and guidelines to avoid the vibration damage to BHAs and their associated downhole tools in the riserless highly deviated wells. The dynamic analysis model is based on forced frequency response (FFR) to solve for resonant frequencies. In addition, a mathematical formulation includes viscous, axial, torsional, and structural damping mechanisms. With careful consideration of input parameters and judicious analysis of the results, the author demonstrates that drillstring vibration can be avoided by determining the 3D vibrational response at selected excitations that are likely to cause them. The analysis also provides an estimate of relative bending stresses, shear forces, and lateral displacements for the assembly used. Based on the study, severe vibrations causing potentially damaging operating conditions were avoided, which posed a major problem in the nearby wells. The study indicates that the results are influenced by various parameters, including depth of the mud line, offset of the wellhead from the rig center, wellbore inclination, curvature, wellbore torsion, and angle of entry into the wellhead. This study compares simulated predictions with actual well data and describes the applicability of the model. Simple guidelines are provided to estimate the operating range of the drilling parameter to mitigate and avoid downhole tool failures.

The homogeneous graft copolymerization of acrylic acid (AA) onto cellulose (CE) using 1-butyl-3-methylinidazolium chloride ionic liquid ([Bmim]Cl) as reaction medium was studied. The effect of various reaction parameters on grafting efficiency, such as monomer concentration, initiator dosage, reaction time and reaction temperature was evaluated. The result showed that the optimum conditions are as follows: the mass ratio of monomer to cellulose 4:1, initiator to cellulose 1:10, reaction temperature, 60℃, reaction time, 2h. The grafting efficiency can reach 96.7% under the optimum conditions. Moreover, the structure of the copolymer was characterized by IR.


Companies have long known that, to be competitive, they must develop a good strategy and then appropriately realign structure, Systems, leadership behavior, human resource policies, culture, values and management processes. Doing insurance business in Rwanda is increasingly becoming a challenge to both established and newly establishing insurance organization. The country is struggling out of serious political turmoil but with a desire to get the country back to shape as demonstrated by the strategies laid down by the Rwandan Government. Multiple evidences from the strategic orientations has failed to catch up with contemporary organizational practices. Although many studies in management literature incorporated strategic orientation, the effect on organizational performance and the relationship between market orientations remains unclear. Some found positive connections between market orientations and organizational performance. The target population was SONARWA's staff and sample size was 80 potential respondents. The descriptive research approach was adopted, where semi-administered questionnaires was applied. Data collected from the field was cleaned, sorted, coded, tabulated and statistically analyzed by using SPSS. The One-Sample T test was applied to compare means computed with hypothesized means. The results obtained concluded market orientation had a significant effect on organizational performance. Thus, competitive advantage pricing and promotions had an influence on organizational performance. A researcher recommended the institutional managers to comprehend the fact that although some elements like market orientation exert a positive and significant effect on organizational performance, there are other elements which can contribute to the business performance of Insurance companies. And it was recommended that a study should be undertaken to find out ways of addressing the challenges that insurance companies are facing such that insurance company can be having a good percentage of market share and other companies are surviving on low market share for a long time without gaining.


Processes that occur within and across the oceanic crust—in particular along mid-ocean ridges and oceanic spreading centers—play a huge role in the dynamics of the Earth. The largest fluxes of heat and material between the Earth's mantle, crust, and seawater occur via magmatic, tectonic, and hydrothermal processes along oceanic spreading centers and their vast flanks. Roughly two thirds of the Earth's surface is accreted through magmatic and tectonic processes along mid-ocean ridges, and subduction of this ocean crust in turn influences mantle compositions. Exchange of elements between ocean crust and seawater strongly influences seawater compositions and leaves a geologic record of fluid-rock reactions in altered ocean crust. Some of these reactions contribute energy to microbial activity of a largely unexplored biosphere. The dynamics of ridge and ocean crustal processes therefore have enormous implications for thermal, chemical, and biological exchanges between the solid Earth and the hydrosphere.


The need for high-resolution seismic imaging of the shallow subsurface has grown rapidly particularly in civil, geotechnical, and environmental engineering. In most cases, P waves have been used. However, P-wave seismics has some fundamental weaknesses that are difficult to overcome. Firstly, P wave can only indirectly (through AVO) address the shear strength of the soil that is of primary interest to the engineers. Secondly, in the shallow (0-50 meter) depth range of interest, S waves are, more sensitive than P waves to changes in soil composition/facies. Finally, P-wave are more affected by the effects of the weathering layer than S waves. In view of these limitations, the application of S waves becomes interesting.


Objective
To observe the effects of lutein on cell proliferation and apoptosis of in vitro culture human cervical cancer HeLa cells.

Methods
Select human HeLa cells of the logarithmic growth phase for the study. Using a random number table method, those HeLa cells were randomly divided into six groups: 20, 40, 80, 160, 320 μmol/L lutein group and control group, then added 200 μL RPMI1640 medium contained final concentration of 20, 40, 80, 160, 320 μmol/L lutein and HeLa cells in 20, 40, 80, 160, 320 μmol/L lutein group, respectively, and added 200 μL RPMI1640 medium only and HeLa cells in control group.The HeLa cells proliferation inhibitory rates were determined by methyl thiazolyl tetrazolium(MTT) assay and the apoptosis rates of HeLa cells were determined by flow cytometry.Analyzed rates of proliferation inhibitory and apoptosis of HeLa cells that cultured the same time but in different concentrations of lutein and cultured in the same concentration of lutein but at different time points by statistical method.

Results
When HeLa cells cultured the same time(24 h or 48 h or 72 h), with lutein concentration increased by turns(20, 40, 80, 160, 320 μmol/L, respectively), compared with the previous low concentration group, the proliferation inhibitory rates and apoptosis rates increased significantly, and the differences were statistically significant(P<0.01); When HeLa cells cultured in the same concentration(20 μmol/L or 40 μmol/L or 80 μmol/L or 160 μmol/L or 320 μmol/L) of lutein, with the culture time extended (24, 48, 72 h, respectively), compared with the previous time point, the proliferation inhibitory rates and apoptosis rates were significantly increased, and the differences were statistically significant(P<0.01).

Conclusions
Lutein can inhibit the cell proliferation and induce the apoptosis of in vitro culture human HeLa cells.The rates of proliferation inhibitory and apoptosis of in vitro culture human HeLa cells could increase with lutein concentration increasing and culture time prolonging.

Abstract : As the millimeter-wave portion of the spectrum comes into more common usage for radar, radiometry, and communication, good nonreciprocal devices such as isolators will be required. The report explores the possibilities of a thin evaporated indium antimonide film in the Faraday configuration as a millimeter-wave isolator. Using a free-electron model, charge carrier concentrations and mobilities that are presently obtained at room temperature in good N-type InSb films are plugged into a computer program which computes Faraday rotation, including the effects of multiple reflections.

In this exploratory study we investigated the use of search and navigation as strategies for retrieval in large collections of digital photos. The main goal of the research was to test out models and methods that can describe retrieval behaviour and preferences. A focus group interview was conducted and demonstrated the need for taking various types of factors and measurements into account. We examined relationships between independent variables (happiness levels, satisfaction with and confidence in the search results, feeling lost during search,), and perceived satisfaction as dependent variable. The analysis showed statistical significant relationships for some important factors, but also indicated limitations in the applied theoretical framework, in particular related to use of emotions as independent variables. The study also showed that users' own perception of which retrieval strategy was the fastest differed from the actual time they used on search and navigation tasks. This confirms the need for analytical models that integrates subjective preferences/perceptions and measurement of objective factors.
