According to the character of two-sided matching problem between venture capitalists and investment enterprises in real-life,the two-sided matching model between venture capitalists and investment enterprises with multiple attributes and different kinds of information is constructed and a corresponding decision method is proposed.Due to the uncertainty of market environment and complexity of objective things,real numbers,intervals,triangular fuzzy numbers,linguistic variables and intuitionistic fuzzy numbers are used to represent the evaluation information.Taking the expectation levels as the reference points,the gain or loss relative to the reference points for each attribute value is computed according to prospect theory.Considering the loss aversion trait of the decision maker's psychological behavior,the comprehensively perceived values of venture capitalists and investment enterprises are calculated by using TODIM(an acronym in Portuguese of Interactive and Multicriteria Decision Making)method.The multiobjective optimization model which maximizes the comprehensively perceived values of venture capitalists and investment enterprises and the income of investment intermediary is established.The maxmin method is proposed to solve this model and then the matching results can be obtained.The example analysis shows the effectiveness and reasonability of the method.


Hypertension affects ~1 in 10 pregnant women in the UK, whilst pre-eclampsia (PET) complicates 2–8% of pregnancies. Hypertensive disease is the 4th leading cause of direct deaths, with recent triennium deaths due to intracerebral causes. This chapter explores the pathophysiology of hypertensive disease and its current management in pregnancy, including the treatment of eclampsia on labour ward. PET is a multi-system disease, which may present across a wide spectrum of organs. Therefore, the anaesthetic plan of management is greatly influenced by the extent of the disease process and which systems may be involved. This chapter provides detailed recommendations for the anaesthetic plan of care, whichever mode of delivery is indicated, and the peripartum critical care management required.


Electricite de France has developed a number of simple, inexpensive radioactive tracer methods for pipe discharge measurement. The equipment is highly adaptable and causes neither flow disturbance nor additional loss of head, nor does it require modification of existing circuits as a general rule. The method described is based on the fluid transit time between two detection stations along the pipe. Discharge is found by dividing the volume between the two measurement stations by the tune the fluid takes to transit from one to the other. To determine transit time, the fluid is "marked" by a tracer with a short half-life, which is produced and fed into the pipe flow by a special "generator/injector" unit. Cesium 137, a radio-element with a long half-life (30 years), produces metastable barium 137, which emits gamma-radiation at 662 keV with a half-life of 2.6 minutes. The cesium is fixed on resin inside a cartridge sealed with filter plugs at both ends. A positive-displacement pump circulates the fluid extracting the barium 137 and stores the resulting aqueous tracer solution in a hydropneumatic accumulator. Direct transit time indication is provided by an electronic detection and processing unit. This equipment is designed to current French regulations, and the "marked" fluid is safe as regards radioactivity.


Based on the investigation of white dutch clover lawn, the spatial distribution pattern of Adelphocoris suturalis Jackson population was aggregative distribution through the analysis of the method of the aggregated index and Iwao's law.The reason resulting in this result was determined by both Adelphocoris suturalis themselves and environmental factors.And also the suitable sample size and Iwao's model of sequential sampling were proposed for a certain precise level.


The invention discloses a medicinal composition and its application in the preparation of medicines for treating obesity, insulin resistance and diabetes. The medicinal composition containing sodium salicylate and oleanolic acid is injected to the abdominal cavity of a diabetic animal to substantially reduce the blood sugar level, and the composition containing sodium salicylate and oleanolic acid is added to a culture solution of differentiated 3T3-L1 adipocytes to substantially inhibit the tumor necrosis factor induced insulin signal disorder, so the composition containing sodium salicylate and oleanolic acid can be used in medicines for treating the obesity, the diabetes, the insulin resistance, and insulin resistance closely related metabolic syndromes.

[Objective] Different levels of dietary iodine were fed to study the relevance of dietary iodine and rabbit muscle and liver accumulation.[Method] A total of 84 rabbit were selected and divided into seven groups according to the principle of sexuality reciprocity.The test groups were added different doses of iodine in the basic diet.The contents of iodine in the muscle and liver were measured.[Result] With the added amount of iodine in diet increased,muscle and liver in the iodine content also increased.When the adding amounts of dietary iodine were 0.2 mg/kg and 0.4 mg/kg,the iodine content of the test group in muscle and liver was higher than that of the control,and the difference was not significant(P 0.05).When the amount of the dietary iodine was above 0.6 mg/kg,the iodine content of the test group in muscle and liver and the control group had significant difference(P0.05).[Conclusion] Iodine content in diets had significant positive correlation to the accumulation of iodine in the muscle and liver.


Atypical fibroxanthoma (AFX) with osteoclast‐like giant cells is a rare entity. We present the case of an elderly woman who presented with a pink–purple dome‐shaped nodule with central hyperkeratotic crust. Biopsy revealed a cellular, dermal‐based tumor comprised of spindle, oval, and osteoclast‐like giant cells with pleomorphism. The immunohistochemistry profile supported a diagnosis of AFX with osteoclast‐like giant cells. We performed a literature review through PubMed and Google Scholar for AFX with osteoclast‐like giant cell formation and found 16 previously reported cases. We aim to provide a review and discuss features of these cases. We also discuss the pathogenesis of these osteoclast‐like cells as well as potential pitfalls in diagnosis.


Faculty of Education York University North York, Ontario Questions about pedagogy move from what constitutes knowledge, understanding and conduct, to concerns with social difference and social inequalities, and to whether language constitutes thought or thought constitutes language. In the end, only one pedagogical question, reflecting the work of a 19th-century French educator, remains of value in the classroom: What do you think? Les questions concernant la pedagogie touchent au savoir, a la comprehension et a la conduite, a la difference et aux inegalites sociales, et a l'enigme suivant: la langue rend-elle possible la pensee ou la pensee engendre-t-elle la langue? Au bout du compte, la seule question pedagogique qui demeure pertinente a l'interieur de la salle de class reflete le travail d'un enseignant du 19eme siecle, a savoir: Que penses-tu? A few pages into Civilization and Its Discontents, one finds Freud struggling with a series of metaphors meant to convey the timelessness of the unconscious. He wants to suggest something beyond juxtaposition -- the problem of the past and present as montage -- but gets tangled in the problem of language, of not being able to express a movement unhinged from chronology. He tries with the metaphor of a city. Suppose one could walk throughout a city and see, at the same time, the chaos of coincidence, ruins persisting within their restorations, traces of the present and past still felt as structures. "And the observer," Freud says, "would perhaps only have to change the direction of his glance or his position in order to call up the one view or the other" (Freud, Civilization, p. 7). Still, such things seem unimaginable and Freud acknowledges "how far we are from mastering the characteristics of mental life by representing them in pictorial terms" (p. 8). One might add that while both research and pedagogy are also quite far away from engaging the characteristics of mental life and in acknowledging learning as a psychic event, a passionate encounter, both research and pedagogy continue to be affected by this life and by their own attempts "to change the direction of one glance or one position in order to call up one view or the other." But suppose one could imagine the unharmonious coincidence of simultaneous chronologies constituting not so much a city but its architectonics, (1) the text a structure of social relation. And suppose one could hear different narrators speaking at the same time, so much so that it would be almost impossible to discern where one voice begins and one continues, where one hesitates and the other carries out a thought that can think against itself. Imagine the possibility of making a non-narrative narrativity, a way of telling that refuses the hierarchies and conventions of origin and of closure, and of teleology -- all techniques most necessary to the fictions of anchoring chronology to the discreteness of certitude. The non-narrative text is not discrete. It asks something of the reader: the reader must decide whether it is interesting to think along, to think against it; whether it is in the detours rather than in the destination that a certain pleasure can be allowed; whether the reader and whether the writer can dispense with the need for explication. This may be the dynamic of friendship. In 1818 a teacher named Joseph Jacotot stumbled on a pedagogy and then wrote about it for the rest of his life. This pedagogy caused a stir. Those who were against it thought this accidental pedagogy would usher in chaos, would signal the end of the world, and would make education, as it was known at the time, a stranger to itself. And others were for this pedagogy, they welcomed what it supposed (and these others already had nothing to lose for they were already deemed discontented by the established authority). The pedagogy Joseph Jacotot stumbled upon was like an anti-pedagogy. It claimed one did not need a teacher to learn; that one could teach what one did not know; that the illiterate could teach literacy; that pedagogy could be reduced to one question: What do you think? …


The excess pore water pressure in the saturated sand was controlled by applying the back pressure to the stratum,so that the degraded saturated stratum with the residual pore water pressure was simulated.Model tests of the soil-pile interaction were conducted to study variations of p-y curves and ultimate lateral resistances of single pile in degraded saturated sand with the increase of the residual pore water pressure.The following results were obtained based on model tests corresponding to the saturated sand with the relative density of 30%.The lateral resistance of the pile gradually decreased with increase of the residual pore water pressure under the same lateral displacements of piles.If there was no residual pore water pressure in the saturated sand,the ultimate lateral resistance of the stratum determined based on model tests was close to the academic value.The ultimate lateral resistances of piles degraded about 30%,55% and 80% respectively if the residual pore water pressure was 0.25,0.5 and 0.75 times the effective overburden pressure of the stratum.The ultimate lateral resistances of the stratum degraded about 90% for liquefied sand,which was consistent with shaking table and centrifugal model test results.


In this paper we study the problem of coloring the edges of a graph for any k-list assignment such that there is no maximal monochromatic biclique, in other words, the k-biclique edge-choosability problem. We prove that the K3free graphs that are not odd cycles are 2-star edge-choosable, chordal bipartite graphs are 2-biclique edge-choosable and we present a lower bound for the biclique choice index of power of cycles and power of paths. We also provide polynomial algorithms to compute a 2-biclique (star) edge-coloring for K3-free and chordal bipartite graphs for any given 2-list assignment to edges.


But the reality of that particular relationship still escapes us. Just how and why did the Madoc myth interact in quite the way it did with the needs of a fulcrum group climbing towards a local hegemony? There are parallels elsewhere and we are none the wiser about them. Gramsci talks a lot about organic intellectuals, about folklore, 'common sense'; he tells us more than anybody else, I think. But he doesn't tell us enough. If we could penetrate to the reality of the Madoc myth in that particular human complex Wales at that particular moment of historical experience and perception of experience, we'd be feeding where the corn of history is green, to quote another Cambro-Briton.


Pharmaceutical activity of pharmaceutical webs in the regional market is studied. The main competitive advantages of pharmaceutical webs before the isolated pharmaceutical organizations are studied. With usage of methods of the theory of fuzzy sets the methodological approach to definition of a degree of economic safety of a pharmaceutical web is offered. The computer program «Pharmaceutical economic safety» allowing is developed and registered to parse a state of economic safety of pharmaceutical webs.


Accurate prediction of runoffs plays an important role in managing water resources in river basins. Conducting runoff prediction is a complex and nonlinear process, therefore suitable for applying tools like Artificial Neural Networks (ANN). A typical algorithm for training the ANN is Back Propagation (BP). But there are two disadvantages for the BP algorithm: slow in convergence, and prone to fall into local extreme points. Therefore, we applied so called GA-ANN hybrid algorithms to predict runoffs. The data from Qing jiang river in between 1989 and 1991 are used as training data set, and 1992 are as testing data set. The historical 3 days daily runoff data were used to predict the upcoming (4th) day's runoff. The precision of the prediction is examined by DC and RMAE. The result showed that, the DC value of GA-ANN hybrid algorithms has increased for 0.12% compared to the traditional BP algorithm, and the RMAE value has been reduced for 1.69%. And in addition, the GA-ANN network is more stable than the traditional BP network.


Rumination and worry are repetitive negative thinking (RNT) tendencies that contribute to the development and maintenance of internalizing psychopathologies. Accruing data suggest rumination and worry represent overlapping and unique transdiagnostic cognitive processes. Yet, prior neuroimaging research has mostly focused on rumination in depression, which points to involvement of resting‐state brain activity in default mode, executive, salience, and/or affective networks.


This paper provides the first geological and paleontological data on two Mexican Paleocene fossil localities, the División del Norte and the Belisario Domínguez quarries, recently discovered near Palenque, State of Chiapas. Both are part of the marine outcrops previously known as the Tenejapa (toward the West) and the Lacandón formations (toward the East and in Guatemala). Since the limits of these formations remain unclear in the Palenque area, the geological association of these localities is referred to as the Paleocene Tenejapa-Lacandón Unit. The fossil fishes are particularly abundant and well preserved in these sites; they represent taxa previously known from Eocene localities around the world, whose strata were deposited under continental and marine conditions. This new assemblage is peculiar because it includes potential new species of Pycnodontiformes, Osteoglossiformes, Anguillifromes, Clupeiformes, and "serranids" that might expand their temporal and paleogeografical distribution worldwide and therefore become important elements to understand the evolution of these groups. These 63 my fish localities are the closest, temporally and geographically, sites to the Chicxulub Crater, a crater intimately associated to the Mass Extinction Event at the Cretaceous-Paleogene boundary (K/P). These newly localities represent an important paleontological scenario that will contribute to achieve a better understanding of the marine vertebrate communities throughout this important geological event.

The Nearest Neighbor Algorithm (NNA) was proposed to predict the structural class of a protein domain according to its amino acid composition. Results obtained through Resubstitution test, Jackknife test and independent dataset test are quite high. Accordingly, the present method, if effectively complemented with the existing prediction methods in this area, may become a powerful tool for predicting the structural class of protein domains


The author analyzes the forms, features, and main directions of visualization within the nationalist text. This article delves into the study of the nationalist imagination and political discourse. Beginning in the late 18th century, nationalism emerged as a social and cultural factor that steered the vectors and trajectories of political development in Western societies. The article examines the forms of interdependence between nationalist discourse and the visualization of political imagination, which plays a pivotal role in the invention and construction of identities. It underscores that the discursive and visual methods of constructing national identities evolved concurrently. Visualization both complemented and recalibrated the primary vectors of transformations in narrative and discursive forms of the nationalist imagination. The political rhetoric of nationalism transitioned into a visual realm, and its visualization resulted in a fusion of the traditions of both "high" and "low" cultures. This visual rhetoric of the nationalist imagination catalyzed the transformation of ethnic groups into modern nations, viewed as imagined communities. While the visual techniques in the nationalistic metatext could vary, they often shared certain characteristics. Visual imagination emerged as an integral component of identity formation in rhetorical discourse. The amalgamation of political and visual rhetoric ensured continuity between various forms of identities and the cultures they fostered. Narrative forms of political rhetoric were enriched by visual ones, especially when the nationalist imagination was crafting and promoting images of Self and Otherness. Throughout the 19th and 20th centuries, the nationalist discourse of European nationalisms operated as a dichotomy, rooted in a blend of political rhetoric and visual imagination.


Acute lymphoblastic leukemia (ALL) is a type of blood cancer that affects white blood cells, primarily affecting children. Early diagnosis is crucial for successful treatment and recovery. In recent years, convolutional neural networks (CNNs) have been increasingly used in medical image analysis, including the detection and classification of ALL from medical images. In this paper, we propose a model called QCResNet for the classification of ALL from peripheral blood smear images. Our proposed model achieved a high accuracy of 98.9% on a dataset of 15,135 images, outperforming several state-of-the-art methods. Our results demonstrate the potential of QCResNet for accurate and rapid effective diagnosis of acute lymphocytes.


the old supporters of the zymotic nature of tetanusthought, some kind of poison resemblinig strychnine was generated by the. bacilli. We may suppose, then, that the bacilli streaming forth, from the point of inoculation, as from a centre, distribute themselves-through the body, and, further, that each bacillus lying in tissues represents a small bult coEstantly acting source of poison, which first affects its own immediate vicinity, but, as a consequence of absorption and in co-operation with others, affects ultimately the whole body, and we may thus explain the local tone and tension, its gradual extension, and, finally, the affetioi 'of the whole system. It is interesting to consider how these organisms exert their baneful influence on the living bodies of the higher animals. Blow, tor example, do the bacilli of splenic fever act upon cattle? There are ;clearly four ways in which we may explain the action of microbes upon 'the infected animal. In the first place, they may act like an invading' army on a peaceful population; they may simply consume their stores 'of pabulum. Possessing greater strength and vitality than the normal tissues, which are highly specialised and perhaps require more complex food-that is, food which has been more or leos highly assimilated,-these young and vigorous warriors seize upon and appropriate the raw material, and practically starve out the more delicately framed cells. And this action cannot be overlooked, in whatever mode we may seek to explain their influence. Their enormous rate of reproduction has been already referred to, and we have only to look at the drawings of Klein and others of the thorough infiltration of many organs to understand what a powerful influence they must exert in this direction, and how the normal cells weakened 'by inanition may tall, like Gulliver before the Lilliputians, vittims to the attacks of their minute but numerous and persevering enemies; %nd, if any further proof were needed, it would be found in the serious effects that are produced upon the economy by any constant drain, whether it be from an imperfectly healed abscess, from leucorrhcea, or even from purulent ophthalmia. Secondly, they may act by interfering with the due performance of the functions of the various depurating organs. Klein, in his numerous and excellent drawings, has frequently represented the kidney, and we see the capillaries of the glomeruli blocked up with myriads of microbes. It is clear that the urea and other final products of the regressive metamorphosis of the tissues must be imperfectly eliminated, and if retained in the body must contribute their share in the development of disease. But another view may be held. It may be said, so far as we know, all living beings produce exereta, the simplest of which, carbonic acid and water, contain the carbon, hydrogen and oxygen of the food; whilst the nitrogen is eliminated in the form of urea or uric acid or guanin, or some other soluble and generally poisonous compound. Microbes can constitute no exception to this rule; but, whereas in most instances the products of excretion are thrown forth into the vast receptacles of the atmosphere or of the waters or of the soil of the earth, and by the play of other forces become harmless, they are here discharged into the body of the animal on which they are living, and so bring about its destruction more or less quickly, but as surely as if that animal's own exereta were retained in its body. There is still another explanation which on many grounds has recommended itself, as accounting more satisfactorily for the phenoniwea observed, both to chemists and biologists. It is that the injurious effects produced by microbes are due, not to what they take or to what they excrete, but to what they leave, and this is closely associated with the imperious demand they make for oxygen. Being in many instances anaerobic-that is, living and multiplying without direct exposure to air-they must obtain the oxygen they require for the process of life from the tissues by which they are surrounded; but when oxygen is withdrawn from such complex chemical compounds as those of which our bodies are constructed, the elements enter into new combinations, and then, under the name of ptomaines (from 7rrTwa, a dead body), are believed to be the really poisonous agents. Attempts have been made to isolate these compounds ; and it has been shown that they are of the nature of alkaloids, and resemble, both in their constitution and in their effects, those deadly poisOns that may be extracted from digitalis, conium, tobacco, delphinum, and other noxious plants. In reference to this, it may just be noted that Miquel (Les Organines Vieants, 1883, p. 103) has cultivated a bacterium which has the singular power of converting a gramme of sulphur in the course of forty-eight hours into hydrosulphuric acid on the addition of four litres of boiling water and some tartrate of ammonium. This bacterium often fixes itself in Vulcanised india-rubber tubes, and in the course ofa few hours can charge the wter they ontain with from 60 ec. to 70 cc. per litre of Blphurettd; hydrogen. The difficulty which must strike everyone in regard to the action of these microbes on the body is the comparative zrvity of disease. How is it, if the air is swarming with these ferocous crobes, that we do not all succumb to their attacks? How can anyone escape? Pasteur meets the difficulty by stating that the healthy body is capable of resisting the attacks of these foreign agents, and that so long as-the surface is intact no harm comes from their ingestion. A healthy man is probably capable of resisting the attacks of the majority of pathogenic organisms, at least for a timQ. The cells which cover the surface of our bodies and line our alimentary, respiratory and genito-urinary tracts possess their own vital energy, and when perfectly normal cannot be invaded by any microbe; they present an impenetrable front to such organisms along their whole line. When, however, by mechanical, chemical, or other injury the vitality of these cells is lowered, a door is opened for the admissions of such organisms, which, having once penetrated the tissues or the blood, find a fit soil for multiplication ; and these may prove, by their mere numbers or by their effects, injurious or fatal to the whole body. NothiDg can demonstrate this better than the experiment recently made,by Orth and Wyssokowitsch (Virchow's Archiv, Bd. ciii., 1886), who found that staphylococcus coald be injected into the blood of a rabbit without apparent injury ; but, if before the injection, a slight mechanical injury was inflicted on the valves of the heart, typical endocarditis was at once produced. In conclusion, I would desire to point out that this branch of inquiry is of quite a special character, and.that it requires very considerable practice and entire devotion of time. Take my own case. I was most desirous to obtain cultures from various diseases of the eye attended with suppuration, to illustrate this lecture, but it is requisite, in the first instance, to have sterilised tubes and plates to grow the microbe, Though pretty well accustomed to delicate operations, very specialprecaution is required to introduce the matter gained without entrance of foreign bodies. Then an incubator is wauted; and, finally, there is the long and difficult examination with the microscope, with all its details of cutting, staining, mounting, and, not least, preserving in an accessible form. On these grounds, I hope that the Council of the College will see fit to institute, with part of Sir Erasmus 'Wilson's bequest, a laboratory devoted to this object, where one or two able demonstrators may continue the study of bacteriology, and prosecute, with all modern appliances, those researchos, which are certain to prove of service in the diagnosis and treatment of disease.


In this paper, a large number of studies of the efiect of the foliage on single or lines of trees on modern wireless communication systems are reviewed. The paper is focused on the experimental works mainly done for commercial applications such as cellular communication and high speed point-to-point flxed link at the microwave and millimeter wave frequencies. For this review study, the development of the foliage loss prediction methods and the factors in∞uencing the tree-induced shadowing efiect are highlighted. In view of current research work in this area, some possible future works are proposed to improve the performance of modern wireless communication systems with the efiect of foliage.


From the foregoing study there is evidence: Of the presence in horse serum of heterophilic antigens of the Forssman type, as shown by the development of a relatively strong antisheep hemolysin in rabbits immunized with large quantities of the serum. Absorption with heterophilic organs removed the hemolysin, while absorption with non-heterophilic organs diminished its titer only slightly, possibly due to physical absorption. The immune sera did not contain agglutinins for sheep red cells, neither did they contain hemolysins and agglutinins for horse and guinea pig red cells.That antistreptococcus serum has antigenic qualities similar to those of plain horse serum, while diphtheria globulin does not stimulate the production of heterophilic antibodies; and that subcutaneous injection of any one of the three sera fails to call forth a response.That the sera of rabbits, as a result of treatment, as outlined, become toxic for the guinea pig. This toxicity is shown to be not identical with the sheep cell hemolysin.

Abstract Inspired by an old result by Georg Frobenius, we show that the unbiased version of Hall's marriage theorem is more transparent when reformulated in the language of matrices. At the same time, we obtain a more general statement applicable to bipartite graphs whose parts need not have the same size.


Abstract The influence of the different thermal boundary conditions at the bottom and top plates on the dynamics and statistics of a turbulent Rayleigh–Bénard convection flow is studied in three-dimensional direct numerical simulations. The flow evolves in a closed cylinder with an aspect ratio of $\varGamma =1/2$ in air for a Prandtl number $Pr=0.7$ and a Rayleigh number $Ra=10^7$ and in the liquid metal alloy GaInSn at $Pr=0.033$ and $Ra=10^7$, $10^8$. We apply for each case three different thermal boundary conditions at the top and bottom of the fluid volume while leaving the solid sidewall thermally insulated: (i) fixed temperature, (ii) fixed heat flux and (iii) conjugate heat transfer which couples the temperature and heat flux in the working fluid to that of the finitely thick, solid plates enclosing the turbulent flow. The global heat transfer is enhanced by up to 19 % for the conjugate heat transfer case in comparison to that of isothermal plates. The differences decrease for the lower of the two Prandtl numbers; they remain generally smaller for the global turbulent momentum transfer. Mean temperature profiles and root mean square velocity fluctuations are surprisingly weakly affected. The largest difference appears for the distribution of local thermal boundary scales when the cases of fixed temperature and of conjugate heat transfer are compared. We also discuss our results in view to experimental uncertainties in liquid metal experiments.


Spiking Neural Networks (SNNs) that require synapse weight initialization using random numbers have been widely used in the neural morphological system. However, the random numbers generated by traditional digital circuits have certain repeatability, and the entire computing architecture has issues such as high resource consumption and low integration. In this letter, a hardware system for true random number generation is realized through integrating a magnetic tunnel junction, a memory cell of MRAM (magnetic random access memory) chips, with an interface circuit and using the same mechanism as writing data in spin transfer torque MRAM. The generated true random numbers are evaluated using NIST SP800-22 standard and are used for synapse weight initialization in an SNN system. The recognition rate of the system initialized by the generated true random numbers is about 84% for an MNIST handwritten digit dataset, which is 2%–3% higher than that using a traditional linear feedback shift register. The reported work provides a new approach for better SNN performance.

The success of product stewardship initiatives will depend on their being cost-effective for the participants. If they are to be imposed by means of legislation, the costs have to be minimized and the profitability maximized if they are not to be seen as a burden on society rather than as part of a general move towards sustainable growth. As manufacturers orient themselves in the direction of product recovery and recycling, certain aspects of the development of recycling-oriented manufacturing systems emerge as paramount to their satisfactory establishment. There must be full collaboration between the various players in the system. This applies particularly to the end users who have traditionally been outside the system. Information must be exchanged between the product recovery operation and the product design activity if the end-of-life performance of products is to be optimized. Who maintains control of the system is a key issue. If control is allowed to pass from the manufacturer to the recovery operator, for instance, there is likely to be a bias in favour of recovering only the most profitable items. For a product recovery scheme to be most cost-effective, the question of value must be properly addressed. The value of most products lies not in their materials or components, although these have some residual value, but in their function.


UK Abstract: Berlin, Alexanderplatz is a novel completed by Döblin in 1929 that marks the pinnacle of Döblin's literary output. The novel tells the story of Franz Biberkopf's difficult survival in Berlin after his release from prison. The dark thread of the novel is Biberkopf's struggle with god of death, in which the theme of sin and punishment is embedded. By analysing and explaining the transformation of Biberkopf's perception of the problem of sin and punishment, it shows the process of his soul's active lowering of its will towards the path of rationalism. It analyzes the Volitionalism, irrationalism and rationalism hidden under the motif of sin and punishment.


Background Enhancing The Global Health Network's online offerings (TGHN eLearning, www.theglobalhealthnetwork. org) through local facilitation of its outputs may enable its uptake by clinical research staff. To explore this issue, we aimed to design and pilot a blended-learning programme in collaboration with South African research team members. Methods A participatory research design was used, with purposively-selected support staff and their line managers. Formative semi-structured interviews with the former and focus group discussions with the latter sought reflection on current learning opportunities and career development experiences and needs. Staff then helped design and pilot a practical, feasible blended-learning programme over an approximately 6-month period. The pilot was assessed on reflections of its value that were elicited in follow-up discussions with participants. Results Forty-five clinical research field workers, nurses, co-ordinators, data managers and laboratory personnel (and their respective line managers) took part. Formative discussions suggested staff generally had the necessary skills for their jobs, however they often lacked time and finances to develop a career path. The blended-learning menu of options for staff that they then co-designed and piloted included: facilitated one-to-one or group TGHN eLearning sessions followed by a discussion forum hosted by a volunteer content-expert; job shadows; guidance in accessing training opportunities/ resources; twinning with other research groups or staff; and a skills-sharing workshop. Feedback on their experience of the programme was very positive from those who got 'hooked', particularly as regards the non-threatening learning environment, building of IT competence and networking opportunities. However, staff's personal time constraints, and our challenges in supporting remote teams, were evident for some despite the pragmatic design. Conclusions This flexible, practical and feasible blended-learning program catalysed the self-development of many research staff in the pilot, and supported their busy line managers. As some challenges remain, the programme may require further modification when implemented in different contexts.


We study the so-called interior transmission problem using the T-coercivity approach. In particular, we prove that this problem, which appears when one is interested in the reconstruction of the support of an inclusion embedded in a homogeneous medium, is of Fredholm type and that so-called transmission eigenvalues form at most a discrete set. The simple technique we propose allows to treat cases, which were not covered by existing methods, where the difference between the inclusion index and the background index changes sign.


This study, was made to investigate the antiviral activity against herpes simplex virus type 1 (HSV-1, strain HF, ATCC VR-260) of the methanol and water extracts obtained from Ferula halophila Pesmen, endemic to Turkey. For this purpose, the plant extracts were evaluated by the colorimetric XTT assay in vitro HSV-1/Vero cell systems. Results showed that both extracts of Ferula halophila possessed anti-HSV-1 activity (EC 50 and SI values for methanol extract were 1035.29 µg/ml and 35.56 respectively; EC 50 and SI values for water extract were 264.45 µg/ml and 130.81 respectively). Keywords: Ferula halophila , Colorimetric XTT assay, Antiviral activity, Herpes simplex virus type 1


Morgagni hernia is a subcostosternal diaphragmatic hernia, and is the rarest form of disease related to diaphragmatic defects. Most Morgagni hernias are congenital, but are rarely diagnosed in childhood. Specific examinations are needed because of reducible symptoms and herniation. Surgical correction is the golden rule for cure of this complicated disease. We report a 57-year-old male patient with diabetic obesity and Morgagni hernia who presented as heart failure and acute renal insufficiency. Dramatic recovery of clinical symptoms and systemic complications occurred after surgical repair. Roentgenographic studies and operative findings are demonstrated as well.


How did Christ die? He was crucified. These are the words repeated over and over on Good Friday with the usual emphasis, "He died for us"—but when we asked the question, "How did he actually die on the cross? No one gave us a good answer.
This topic for a short noon day Lenten talk was assigned to us by our minister two years ago and it stimulated us to inquire into the medical aspects of this form of death. The Bible accounts of all four of the gospels are terse and matter-of-fact with almost complete omission of any physiological details.
When we read the theological concepts of the execution from such books as The Day That Christ Died by Jim Bishop, or in The Week That Changed The World, and many others, we found interesting narratives developed by the authors but without any real medical perspective. The historical literature covering that period in books such as Caesar and Christ by Will Durant afford us a fair understanding of this technique of execution as the Romans practiced it. We learn that crucifixion was mentioned by Herodotus in early Greek history, and the Roman historian Pliny wrote that Tarquinus Priscis invented the Roman crucifixion which came into general use between 260 and 160 B.C., two hundred years before Christ.  The historians emphasize that Rome ruled by terror and that the technique of crucifixion, which Cicero described as the "most cruel and hideous of tortures," became the designated method of execution for slaves and insurgents against the state. Into this latter class Jesus fell as Pilate pronounced his sentence: "PoneCrucem servo" (Place a cross on the slave).


The development of simulation technology provides a technical base for multimedia teaching to realize three-dimensional,dynamic,extensive forms,but how to apply simulation technology to improve the quality of modern education is a challenge the college teaching is facing.For reforming education,the ways to combine simulation technology with modern educational means are studied from the aspects of space state,dynamic process and net classroom etc,and the search is useful for better applying simulation technology.Rational application of simulation technology to the modern education can improve students' study interest,help students form knowledge model,expand educated objects and reduce educating cost so that bring better educating effect than tradition education.


This paper presents a study of the effect of load on the retention of the tribofilms formed at the interface of a dry sliding contact between exhaust valve material, Nimonic alloy (N 80A) and valve‐seat material, ductile cast iron (GGG‐40), at a temperature of 500 °C. The role of tribofilms in influencing friction and wear behaviour at elevated temperature is highlighted. Reciprocating pin‐on‐disc experiments were conducted using a hemispherical shaped pin sliding against a flat disc at 20 Hz oscillating frequency, 2 mm stroke at loads of 20 N to 50 N. Low coefficient of friction, in the range of 0.13 to 0.15, was observed at loads up to 40 N whereas at a load of 50 N, the average coefficient of friction increased to 0.29. Optical and scanning electron micrographs with energy dispersive spectroscopy analysis indicate evidence of formation and retention of well compacted and strongly adhering tribofilms at loads up to 40 N. At 50 N, even though more abrasive wear is seen, initial deterioration and subsequent reforming of the tribofilms with increasing sliding time is observed. Overall, more wear was observed for the valve‐seat material as compared to the valve material. Raman spectroscopy primarily indicates the presence of hematite on the worn surfaces at loads of 20 N to 40 N, whereas magnetite presence is strongest at the highest load of 50 N. Increase in tribofilm hardness was observed with increase in contact load whereas the thickness of the tribofilm was not significantly affected by the contact load.


Objective\ To compare the difference between the craniofacial hard tissue of skeletal Class Ⅲ malocclusion and that of normal occlusion in mixed dentition, and to speculate the etiologic mechanism and craniofacial development trend of skeletal Class Ⅲ malocclusion. \ Methods\ Thirty eight children with skeletal Class Ⅲ malocclusion in mixed dentition were selected as a study group, and another 40 children at similar mean age with normal occlusion served as a control group. Lateral cephalometric radiographs at central occlusion were taken.\ Results\ In the linear analysis of the hard tissue, 11 variables in male and 10 variables in female were significantly different between the study group and the control group( t=2.083-2.569,P0.05; t=2.827-3.476,P 0.01). Seventeen variables in angular measurement of the hard tissue were significantly different between the two groups ( t=2.245-2.672,P0.05; t=2.937-3.429,P 0.01). Five variables in the ratio of linear measurement differed significantly( t=2.189-3.528,P 0.01). \ Conclusion\ Mandibular hyperplasia is the main factor responsible for Class Ⅲ malocclusion. Disharmony of craniofacial relation leads to skeletal malocclusion.

Purpose
This study is a comparative organizational analysis of the four subsectors of the Indian information technology (IT) industry, namely, IT service (ITS), business process outsourcing (BPO), software products services (SPS) and engineering and R&D (ER&D). The purpose of this paper is to empirically identify the cross-sectorial attributes, organizational characteristics and the talent best suited to it.

Design/methodology/approach
Data were collected using a qualitative research design with semi-structured interviews of 17 industry experts.

Findings
Findings suggest there are differences in the internal organization of each subsector and this influences the talent attracted toward it. ITS and BPO are perceived as customer driven sectors where technology is an enabler to facilitate smooth functioning of customer operations. Conversely, technology is the core factor that drives SPS and ER&D. Similar observations and differences in the design, environment, individual motives and competencies are identified. The study also identified the inter-relationships between organizational characteristics, task and social structures in the IT industry using Perrow's organizational theory.

Research limitations/implications
The findings identify contextual dimensions and shared patterns that exist between the subsectors. At the same time, it distinguishes each subsector in terms of observable and objective characteristics. Significantly, the study highlights the inter-relationships between technology, task, raw material, goal and social interactions. However, the authors stop short of framing hypotheses to test the relationships identified here.

Originality/value
This cross-sectorial study delineates between the four subsectors and provides a foundation for pursuing future investigations in the right direction. This attempt to systematically analyze and compare all the subsectors of the IT industry simultaneously is a distinctive approach. The sectorial diversity suggests a need for talent management practices that will fit the unique characteristics of each subsector.


Coming from the perspective of historical sociology, the epilogue highlights some systematic features of apologetics as approached in the volume. First, apologetics serves as a seismograph of social change. Second, it expresses and constitutes a relation with an outer and inner opponent as well as with an audience. Third, it relates to different levels of society: to the meso-level of religious and irreligious groups and organizations, and to the micro-level of individuals as iconic figures in the defence of faith. On both levels, however, the 'big picture' is always evoked. Finally, apologetics is discussed with reference to the "Multiple Secularities"-approach as one of the arenas in which disputes about the place of religion and its limits are fought.


There are many problems in the traditional test paper correction system. The thinking and implementation of test paper automatic correction system based on COM technique is given and the COM embedding,COM designing and development platform application in details are discussed as well.


Abstract Disposable solid-electrolyte cells have been used to follow the oxidation level of slags containing from 1 to 40 % Pb, covering the range of both blast furnace slags and lead-rich slags from the Hoboken two-step smelting process.The measured oxygen potential, the lead content of the slag and the temperature were correlated by semiempirical equations. By considering separately the results for each furnace and each type of charge, one can predict the lead level of a slag from an oxygen potential measurement with a standard relative error of about 10%.The results are in reasonable agreement with published thermodynamic data. They yield an apparent activity coefficient for PbO, relative to the liquid state, and including possible metal entrainment effects, of about 0.9 at 1150°C in blast furnace slags.The cost of a determination is similar to that of a routine elemental analysis of the slag.The method has the advantage of giving instantaneous readings, and is of particular interest for the new proces...


Sequence variations exist at defined positions within genomes and are responsible for individual phenotypic characteristics, including a person's propensity toward complex disorders such as heart disease and cancer. As tools for understanding human variation and molecular genetics, sequence variations can be used for gene mapping, definition of population structure, and performance of functional studies. The Single Nucleotide Polymorphism database (dbSNP) is a public-domain archive for a broad collection of simple genetic polymorphisms. This collection of polymorphisms includes single-base nucleotide substitutions (also known as single nucleotide polymorphisms or SNPs), small-scale multi-base deletions or insertions (also called deletion insertion polymorphisms or DIPs), and retroposable element insertions and microsatellite repeat variations (also called short tandem repeats or STRs). Please note that in this chapter, you can substitute any class of variation for the term SNP. Each dbSNP entry includes the sequence context of the polymorphism (i.e., the surrounding sequence), the occurrence frequency of the polymorphism (by population or individual), and the experimental method(s), protocols, and conditions used to assay the variation. dbSNP accepts submissions for variations in any species and from any part of a genome. This document will provide you with options for finding SNPs in dbSNP, discuss dbSNP content and organization, and furnish instructions to help you create your own (local) copy of dbSNP.


Oral squamous cell carcinoma (OSCC) is a malignant solid tumor characterized by hypoxia. Autophagy is considered to play a protective role in cancer cells under hypoxia. A variety of microRNAs (miRNAs) that play a critical role in tumorigenesis have been identified. However, the underlying mechanisms of miR-150 in OSCC development remain unclear. In this study, we observed decreased downregulated expression of miR-150 in association with increased expression of BNIP3 in CAL-27 cells under hypoxia. Hypoxia induced the initiation of the BNIP3-mediated autophagic process, and overexpression of miR-150 inhibited hypoxia-induced autophagy. In addition, we demonstrated that miR-150 inhibited autophagy by negatively regulating the expression of the BNIP3 gene. Collectively, our study identified miR-150 as a key modulator of autophagy by inhibiting BNIP3 in OSCC cells.


A government department in the UK set up a division devoted to ensuring that businesses keeping personal data on employees, customers, and anyone else they had contact with, complied with the Data Protection Act of 1998. The Information Commissioner's ICO set up a regulatory action division to focus on companies that had ignored the law. The rules around data protection legislation are getting tougher. Lax companies and organisations are penalised for failing to comply with the rules and regulations. In this article the author lays down the law about how to avoid prosecution under the DP Act.


We present a new algorithm for optical properties recovery, based on the GPU accelerated of the MCML algorithm for solving the light propagation problem and a Genetic Algorithm as a search method.


To achieve both diversity gain and coding gain, the design of space-time turbo trellis coded modulation (ST turbo TCM), which is based on the turbo structure, has been proposed in the literature. The aim of this paper is to study the effect of finite-word length representation on the performance of ST turbo TCM. We present the investigation of bit-width optimization for an 4-state QPSK ST turbo TCM decoder based on the symbol-by-symbol (SBS) logarithm-maximum a posteriori (log-MAP) algorithm on a quasistatic fading channel. The decoder structure utilizes a sliding window algorithm for reducing memory requirements and decoding latency. Simulation results show that ST turbo TCM is feasible for finite word length representation without significant degradation in the frame error rate (FER) performance. The optimum word length configurations are defined for all quantities external and internal to the SBS log-MAP decoder


Biochemistry is a core subject in the cross‐disciplinary training on Biotechnology engineering courses. Metabolic pathways teaching has traditionally integrated hands‐on laboratory experiences and traditional lectures, which detail a large number of reactions at a molecular level, their enzymes and regulation. The current scenario of Covid‐19 outbreak have motivated the development of complementary tools that expand the horizon of metabolism teaching. In this study, we employed a story‐based methodology to strengthen the metabolic pathways learning and to measure students' perception. Specifically, a peer‐reviewed tale describing the ketone body metabolism was used during five semesters as a didactic strategy to teach this biochemical process. A questionnaire assessed the students' understanding and acceptance of the methodology (n = 83). Our findings showed that a high proportion of students (83.13%) were able to relate the story to the topics studied in the classroom (ketogenesis and ketolysis). On the other hand, they were satisfied and suggested that such methodology is effective and fun. In summary, most of the survey responses related to acceptance of story‐based strategy ranged from 72% to 97%. Collectively, these results indicated that the story is appropriate to decomplex pathways, becoming a simple tool for driving motivation, learning and engagement of students. The narrative represents a bridge to connect the intriguing series of chemical reactions involved in the anabolism and degradation of 3‐hydroxybutyrate (3‐OHB), acetoacetate, and acetone with previously learned knowledge, emotions, and key concepts. In conclusion, the tale was useful to decode ketone body‐related pathways and making metabolism learning more interesting and easier.


When Paul Rudolph was commissioned to design a new university campus for East Pakistan in the mid-1960s, the project was among the first to introduce the expressionist brutalist lexicon of late-modernism into the changing architectural language of postcolonial South and Southeast Asia. Beyond the formal and tectonic ruptures with established colonial-modern norms that these designs represented, they also introduced equally radical challenges to established patterns of domestic space-use. Principles of open-planning and functional zoning employed by Rudolf in the design of academic staff accommodation, for example, evidently reflected a socially progressive approach – in light of the contemporary civil rights movement back in America – to the accommodation of domestic servants within the household of the modern nuclear family. As subsequent residents would recount, however, these same planning principles could have very different and even opposite implications for the privacy and sense of security of Bangladeshi academics and their families.

 The paper explores and interprets the post-occupancy experience of living in such novel 'ultra-modern' patterns of a new domesticity in postcolonial Bangladesh, and their reception and adaptation into the evolving norms of everyday residential development over the decades since. Specifically, it examines the reception of and responses to these radically new residential patterns by female members of the evolving modern Bengali Muslim middle class who were becoming progressively more liberal in their outlook and lifestyles, whilst retaining consciousness and respect for the abiding significance in their personal and family lives of traditional cultural practices and religious affinities. Drawing from the case material and methods of an on-going PhD study, the paper will offer a contrapuntal analysis of architectural and ethnological evidence of how the modern Bengali woman negotiates, adapts to and calibrates these received architectural patterns of domesticity whilst simultaneously crafting a reembraced cultural concept of femininity, in a fluid dialogical process of refashioning both space and self.


The Exxon Nuclear Company, Inc., acting as a subcontractor to EG and G Idaho Inc., Idaho National Engineering Laboratory, Idaho Falls, Idaho, conducted a laser beam welding study to attach internal stainless steel thermocouples into stainless steel upper end caps in nuclear fuel rods. The objective of this study was to determine the feasibility of laser welding a single 0.063 inch diameter stainless steel (304) sheathed thermocouple into a stainless steel (316) upper end cap for nuclear fuel rods. A laser beam was selected because of the extremely high energy input in unit volume that can be achieved allowing local fusion of a small area irrespective of the difference in material thickness to be joined. A special weld fixture was designed and fabricated to hold the end cap and the thermocouple with angular and rotational adjustment under the laser beam. A commercial pulsed laser and energy control system was used to make the welds.


We demonstrate a voltage tunable two-color quantum-well infrared photodetector (QWIP) that consists of multiple periods of two distinct AlGaAs/GaAs superlattices separated by AlGaAs blocking barriers on one side and heavily doped GaAs layers on the other side. The detection peak switches from 9.5 μm under large positive bias to 6 μm under negative bias. The background-limited temperature is 55 K for 9.5 μm detection and 80 K for 6 μm detection. We also demonstrate that the corrugated-QWIP geometry is suitable for coupling normally incident light into the detector.


In this work, we study the epoxidation reactions of coumarin and monoterpene such asimperatorine 1 and myrcene 2. Using DFT method with three hybrid functional such asB3LYP and B3PW91 and the basis 6-311G*, we discuss from thermodynamic and kinetic thepossibility and the stereoselectivity of these reactions. The study of the frontier orbitals hasallowed us to compare the reactivity of these molecules in the epoxidation reactions.

In this study, a high frequency piezoelectric energy harvester converted from the human low vibrated motion energy was newly developed. This hybrid energy harvester consists of the unimorph piezoelectric cantilever, the pendulum and a pair of permanent magnets. One magnet was attached at the edge of cantilever, and the counterpart magnet at the edge of pendulum. The mechanical energy provided through the human walking motion, which is a typical ubiquitous existence of vibration, is converted to the electric energy via the piezoelectric unimorph cantilever vibration. At first, we studied the energy convert mechanism and analyze the performance of novel energy harvester, where the resonance free vibration of unimorph piezoelectric cantilever generated a high electric power. Next, we equipped the counterpart permanent magnet at the edge of pendulum, which vibrates with a very low frequency caused by the human walking. Then the counterpart magnet was set at the edge of unimorph piezoelectric cantilever, which vibrated with a high frequency. This low-to-high frequency convert "dual vibration system" can be characterized as an enhanced energy harvester. We examined and obtained average values of voltage and power in this system, as 8.31 mV and 0.33 μW. Those results show the possibility to apply for the energy harvester in the portable and implantable Bio-MEMS devices.


The switching process of transistor Schmitt circuit was studied in this paper. Concrete analytical expressions of the switching process have been derived. Using these expressions numerical calculations were carried out for two types of commonly used transistor Schmitt circuit. Experiments were carried out to check the theoretical calculations. Experimental results fit the theoretical calculations quite well. From this study, some rules for selection of the transistors and circuit elements were obtained. The results of calculation in this paper may be used to estimate the switching speed of Schmitt eircuit in the early design stage.


This paper deals with the subject of the various relations existing between intellectual property and the right to health. Reference will be made, within the industrial property system, especially to patents, as a crucial instrument in the development of the pharmaceutical industry, which in turn has afforded the world's population greater and better access to health systems. Clearly therefore, it is by no means frivolous to suggest that industrial property protection systems, by means of patents in this case, have managed to make a profound contribution to the development and improvement of the health of the general public throughout the world, by creating a situation in which the right to health, as a first-generation human right, namely one of those relating to the individual, becomes a reality.


Abstract Almost no one today doubts that AI systems will increasingly affect our lives in the near future. Growing interactions of humans with non-human intelligent systems are both a source of threats and a source of hopes. In this paper, some ethical challenges in the development and application of weak and strong AI systems are analyzed. Then, legal challenges that appear when legislators attempt to regulate uncertain and unpredictable phenomena such as AI are discussed. Here we show that despite these challenges, an appropriate law is the most optimal response to threats and hopes related to AI. We also point out that the development of AI will be a major political challenge. Politicians will have to find a difficult compromise between, on the one hand, consenting to the inevitable and essentially beneficial technological development for humanity and, on the other hand, certain risks and dangers, probably also inherent in the specificity of AI functioning.


Twenty-four of 50 individuals were concurrently using drugs reported to have anticholinergic activity. Table 1 provides an overview of population characteristics, drug use, and ADS scores before and after pharmacist-guided interventions in individuals with an ADS score of 2 or greater. Ten of 28 outpatients (35.7%) and four of 22 inpatients (18.2%) had a score of 2 or greater. In individuals with an overall score of 2 or greater, the median ADS score was significantly reduced, from 2.5 to 1.0 (P = .009), after pharmacist intervention.

Electron gas in the conduction channel of a Field Effect Transistor (FET) can support collective plasma oscillations tunable by the gate voltage. In the Dyakonov-Shur terahertz (THz) detector, nonlinearities in the plasma wave propagation in the gated channel of a FET lead to a constant source-to-drain voltage providing the detector output. We present the detector theory in the frame of the hydrodynamic model using the electron plasma Navier-Stokes and thermal transport equations, thus fully accounting for the hydrodynamic non-linearity, the viscosity, and pressure gradients in the detector response. Both resonant and broadband operations of the high electron mobility transistor (HEMT) based plasmonic detectors are described by this model. The relation between the electron channel density and gate voltage was modeled by the unified charge control model applicable both above and below the threshold voltage. The theoretical results are compared with the response measured in the short channel InGaAs HEMT and...

The condom is now on show in the Cairo Museum alongside the more famous artefacts which goes to show that one cant be too careful - even in the afterlife! (excerpt)


Compared with the traditional doubly-fed induction generator (DFIG), the brushless doubly-fed induction generator (BDFIG) eliminates the slip rings and brush gear, which has the benefit of low maintenance costs and high reliability. It thus promises broad application prospects in power generation. The whole generation system should operate in both stand-alone mode and grid-connected mode to provide uninterrupted and continuous power to critical loads. The two operating modes have different control structures due to separate control targets, increasing the control complexity of the power generator system. This article proposes the control winding (CW) current-oriented vector control method for BDFIG in grid-connected mode, which has unique advantages in stand-alone mode. First, the modified variables are obtained under the CW-current rotating frame; Second, the power expression of the system is deduced according to the modified variables; Third, the angle of CW was chosen as a new control degree of freedom based on phase-angle control to realize power control. The proposed control strategy analyzed the control principle of CW-current amplitude and angle control in detail. This method adopts the same orientation strategy with stand-alone mode, which avoids the switching of orientation strategy in different operation modes, thus simplifying the system design a lot. Moreover, considering the same criteria GSC control, reactive power compensation, the control during grid voltage recovery and so on, the large CW-current can be limited at a safety level once the overload or grid faults happened, which can easily achieve Low-Voltage-Ride-Through (LVRT) and significantly increased security and stability of the system. Finally, the proposed control strategy is verified by the experimental results.


The literature on immigrants punctuates their difficulties with language acculturation and communication. Minimal attention has been given to the diversity of immigrant family communication issues in relation to the receiving communities in which they have lived, and research has not assessed immigrant families' strategies for minimizing communication breakdown. Based on in-depth interviews with 20 immigrant mothers and their adult daughters, we examine language acculturation and communication experience within the context of characteristics of the receiving community. The findings demonstrate the previously hidden complexity of language acculturation and communication experiences within mother-daughter dyads and highlight the variety of problem-solving strategies they employ to maintain strong ties despite language difficulties.


Unlike evaluation strategy (ES) and evaluation programing (EP) genetic algorithm (GA) strongly depends on the given search space for the optimal solution problem. The interval of existing optimal solution is unknown in most practical problem, then the suitable search space can not be given and the performance of GA are influence grently. A self-adaptive search space expansion scheme (SA-S~2ES) is proposed to cure this problem. It contains two steps: coarse-step and fine-step. The formen can quickly find a more coarse search interval including the overall situation optimal solution and the latter can refine this interval iteratively. The more precise lower and upper bounds can be obtained with this scheme from any initial search space. It is suited quickly to new suitability bend surface when dynamic environment is used. Simulation experiment results substantiate excellent performance of SA-S~2ES.


The Eureka River landslide of June 1990, at 50 Mm3, is one of the largest historical landslides on the Interior Plains of Canada. It is one of seven large translational landslides to have occurred in the Peace River Lowlands within the last 65 years. Each landslide occurred in Quaternary sediments deposited within a preglacial valley. Each landslide formed a dam. The rupture surface of the Eureka River landslide in preglacial lacustrine sediment, 125 m below the Peace River Lowlands plains, extended beneath the river channel causing the channel to be elevated. The resulting landslide dam was over 20 m high, forming a lake exceeding 8 km in length. The river cut a new channel around the toe of the landslide, abandoning the prelandslide channel. As the new channel is free of armour, incision has been rapid. After 10 years, the dam now stands approximately 5 m high.Key words: landslide, landslide dam, Peace River, Alberta, preglacial valley, geomorphology.


Epidemiological studies suggest a close association between diet and cancer initiation, which provides evidence that the dietary components may be effectively developed as chemopreventive agents[1]. These pieces of evidence are further supported by several case-control and cohort studies, which overwhelmingly support a converse association between the intake of phytochemicals and cancer risk[2,3]. A number of clinical studies have been conducted demonstrating that dietary phytochemicals have the ability to inhibit tumorigenesis[4]. Components present in fruit and vegetables termed "bioactive" phytochemicals belong to several classes of micronutrients, including flavonoids,

The aim of the study is to chronicle the challenges and suggest amendments in policies associated with planning, promotion, implementation and adoption of livestock insurance in tribal communities of Koraput tract in the Eastern Ghat mountain range, India. Two hundred tribal households in six villages belonging to Kandha, Penthia and Poraja communities were selected for the study employing methodologies such as focus group discussion and a structured questionnaire. The findings revealed the inefficient approaches followed in risk mitigation planning for animal husbandry activities involving small and marginal farmers in India. The findings also highlighted the absence of national level planning for encompassing the climate resilient indigenous breeds of cattle under livestock insurance. Lack of insurance coverage for unorganised backyard poultry farming, supporting livelihood of small and marginal farmers, was identified as a challenge for sustainable integrated farming. Policy recommendations were devised in consultation with tribal farmers for promotion and adoption of livestock insurance in tribal communities. These recommendations comprised social, financial and policy advocacy initiatives for a holistic approach towards risk management. Innovative solutions suggested by tribal farmers such as employment of advanced information and communication tools for accessing technical guidance of veterinarians reflected the need and the willingness of the agrarian communities to adopt sustainable animal husbandry practices. A comprehensive plan in participatory mode with the tribal communities was developed to promote food and nutritional security through sustainable agriculture in the hilly terrains of Koraput tract.


The purpose of this study was to assess the influence of the robo-horseback riding exercise with riding posture and speeds on muscle activity of neck and upper trunk in health adults. Subjects(n=31) performed robo-horseback riding with three different kind of postures(hyper-lordotic posture: HLP, neutral posture: NP, slumper posture: SP) and two kind of speed conditions(moderate speed: MD, fast speed: FS). Muscle activity of neck and upper trunk(sternocleidomastoid: SCM, upper trapezius: U-Trap, cervical elector spinae: CES, thoracic elector spinae: TES, lumbar elector spinae: LES, internal oblique: IO, rectus abdominis: RA) were recorded during the robo-horseback riding. According to this study, main effect of muscle activity with SCM, TES, and IO depended on the riding posture(p . Therefore, neutral posture was especially important for healthy robo-horseback riding.


This paper presents the linkages between three essential components of real time flow monitoring in south Florida: the supervisory control and data acquisition (SCADA) system, the hydrodynamic model used to estimate discharge (FLOW), and the corporate database for archiving hydrologic data (DBHYDRO). Water resource assessment in South Florida involves flow computation at more than 400 major water control structures consisting of spillways, weirs, pumps, culverts and combination structures. The water control structures are spread over an area of about 46,600 square kilometers (18,000 square miles) in 16 counties, extending from south of Orlando to the Florida Keys. A network of canals and levees, with a total length of about 2,896 kilometers (1,800 miles), control surface water flow that is characterized by reversals of hydraulic gradient and direction due to low and flat relief. FLOW determines magnitude and direction of discharge through control structures and open channels, incorporating real time hydrodynamic data from remote sites and static parameters extracted from DBHYDRO. Daily flows, archived in DBHYDRO, provide historical records for decision making on flood control, water quality enhancement, water supply planning, and ecosystem restoration. Flow values in oneto fifteen-minute intervals provide vital information for real -time operation of major control structures and the regional water storage system. Instantaneous data are also used for real-time, automatic flow-proportional water quality sampling. A data quality improvement process is in place, involving discharge -rating evaluation, field data collection, and calibration of flow equations. The reliability of flow data has improved significantly as a result of the process.


The infrared spectra of poly(ethylene terephthalate) γ-irradiated in presence of organic solvents were recorded over the spectral region 200–300 cm−1. The analysis of these spectra showed that the combined effect of solvent and γ-irradiation results in appearance of two strong bands at 1550 and 1630 cm−1, increase in the intensities of the gauche bands at 1450 and 1370 cm−1 and decrease in the intensity of the trans-band at 1340 cm−1. The aromatic ring C=C stretching band at 1410 cm−1 was also affected. The profound spectral changes were observed only in samples irradiated in presence of solvents and were not observed in samples treated with solvents or only irradiated in atmosphere of air, these spectral changes were attributed to the changes in the intermolecular of intramolecular forces as a result of penetration of solvent molecules in the polymer and the ionizing effect of γ-iffadiation. It was found that the extent of the intensity variations depends on the nature of the solvent.


Europe is often described as "flooded" by migrants or by Muslim "others," with Western African men especially portrayed as a security risk. At the same time the intensified mobility of privileged people in the Global North is celebrated as creating an increasingly cosmopolitan world. This book looks critically at racialization of mobility in Europe, anchoring the discussion in the aspiration of precarious migrants from Niger in Belgium and Italy. The book contextualizes their experiences within the ongoing securitization of mobility in their home country and the persistent denial of racism and colonialism that seeks to portray the innocence of Europe.


At the present moment there is no proven information regarding gender and age of physical development issues in Russia in children and young people. Objective. Identify the variants of deviations in the physical development of schoolchildren in a large industrial city of Russia on the example of the city of Ufa. Material and methods. Study included 5561 girls and boys, aged 6 to 18 y.o., studying in general schools of Ufa. Based on gen- der and age, the key morphometric indicators were analyzed: height, body weight, chest circumference and BMI (body mass in-dex). Results. Every fourth schoolchild had physical development issues. The excess body weight and obesity were prevalent in the cas- es of deviation ( p <0.05), the undernutrition and growth pathologies were identified much less frequently. Identified specifics characteristics based on age and genders in overweight/obesity schoolchildren. Males dominated among overweight children ( p <0.05). The prepubertal and pubertal peaks of the detection of these pathological conditions in schoolchildren of both sexes were deter-mined. Conclusions. The study demonstrated a real specific of physical development for schoolchildren in Ufa correlated with current main trends of health development in megapolises of Russia for young population. Obtained data should be taken into account in the development of comprehensive preventive programs to protect the health of children and adolescents on a national level.

A novel type of wide angular aperture noncollinear acoustooptical tunable filter (AOTF) configuration in uniaxial crystals is described. These AOTF configurations have a very high figure of merit and operate at a few GHz. They are very attractive because of the recent advent of efficient GHz multilayer ZnO transducers. A formulation is presented which allows an analytical solution for the dependence of the Bragg angles with respect to both the refractive indices and the acoustic wave propagation direction. As a consequence it is shown that, provided the figure of merit is nonzero, these configurations are obtained for any acoustic wave propagation direction. This is in contrast to previously reported noncollinear AOTF configurations which are only obtained when the acoustic-wave propagation direction is constrained to lie within an angular range depending only on the refractive indices of the medium. AOTFs based on the proposed configurations are analyzed in TeO/sub 2/, LiTaO/sub 3/, quartz, Al/sub 2/O/sub 3/ and Te and illustrative calculations related to the tuning curves, the figure of merit and the resolution in these materials are given.<<ETX>>


An experiment of heat transfer on a wall in a laminar flow was performed by using a wall jet. The wall jet was generated by a flow control plate which was inserted into the wall. The heat transfer coefficients were measured by Mach-Zehnder interferometer. The flow pattern and velocity were measured by a smoke-wire method and laser doppler velocimeter, respectively. The height of plates (h) was varied from 2 to 8 mm. The spaces between wall and plate (c) were varied from 0 to 7.6mm. The inclined angles of plate (θ)were varied from 60 deg to -60 deg at the constant front projected height. The following results were obtained. The large plate height gave a large local heat transfer coefficient. The local heat transfer coefficients were enhanced about 7-fold of whithout plate at h=8 mm, θ=30 deg, and c/(c+h)=0.15. The optimum inclined angle of control plate for maximum local heat transfer was 30 deg, and the optimum wall jet generator angle for heat quality was -30 or -45 deg.


Endogenous oxidative damage to brain mitochondrial DNA and consequential disturbances of gene expression and mitochondrial dysfunction have long been implicated in aging and the pathogenesis of neurodegenerative diseases. It has yet to be determined, however, whether mitochondria in brain cells contain an active DNA repair system and, if so, how this system functions. Therefore, the capacity for the repair of defined types of oxidative DNA lesions has been investigated in adult rat brain mitochondria. Using in vitro DNA incorporation repair assay, we have detected base excision repair (BER) activity for the common oxidative DNA adduct 8‐hydroxyl‐2′‐deoxyguanine (8‐oxodG) in mitochondria protein extracts from cortical tissues and cultured primary cortical neurons and astrocytes. The levels of BER activity were both protein concentration‐dependent and repair‐incubation time‐dependent. To resolve the BER pathway, the activity of essential BER enzymes was examined in mitochondria using oligonucleotide incision assay, DNA polymerase assay, and DNA ligase assay employing specific DNA substrates. Mitochondrial extracts were able to remove specifically 8‐oxodG, uracil, and the apurinic/apyrimidinic abasic site from substrates. Moreover, a gamma‐like DNA polymerase activity and a DNA ligase activity were detected in mitochondiral extracts, based on the formation of specific repair products. These results demonstrate that adult brain mitochondria possess an active BER system for repairing oxidative DNA lesions. This repair system appears to function by sequential actions of DNA repair enzymes that are homologous to, but not identical to, that in the nucleus. Thus, BER may represent an endogenous protective mechanism against oxidative damage to mitochondrial, as well as nuclear, genomes in brain cells. J. Neurosci.

ABSTRACT Growing scholarship on the pedagogical applications of statistical modeling is currently taking place to create adaptations of this practice to introduce novices to statistics. These are intended to promote novices' reasoning, and are typically void of formal mathematical procedures and calculations. In this article, we define the potential product that novices can create as they engage in such informal implementations, Informal Statistical Models (ISM), as purposeful representations – with both deterministic and stochastic components – of how observed variability in data is generated. This definition reflects the potential connection between informal constructs that novices and young students can create and the formal view of statistical models, thereby suggesting how informal insights may be later cultivated into more mature understandings. We illustrate the usefulness of this definition by providing an in-depth account of the reasoning that a pair of sixth-grade students employed through their informal statistical modeling process. The findings illustrate a four-episode sequence where students created and developed an initial deterministic model before extending it with an informal stochastic component. This shows how starting with deterministic models can be a valuable precursor to develop initial ISMs.


The desire of humankind that longed for reappearance of visual makes progress within the development of linear history. The directing point at the moment was the `eye`. Upon completion of setting the aiming point, visual image attempts reflection of main agent beyond reappearance of it and, by extension, aimed to visualize desire which was latent in the instance of main agent. It was able to experience a fantasy in paintings, photos and movies as a stage of desire, of course. Digital, however, suggested a new phasis in creating a fantasy world. This study aimed to research the fantastic nature in digital image that a fantastic image is created as a reflection of both independence and unconsciousness. As a result of research, this study revealed that digital image, as a channel that image and imaginative desire which were saved in id, is created as a perfect stage on the basis of verisimilitude, granting an experience toward realization of desire to a main agent raising id which was repressed by the ego and superego to the surface.


Conclusion Developing new in-house assays or verifying commercial kits in hospital laboratories is increasingly challenging due to strictening regulatory and accreditation requirements. For example, ISO 15189 and the upcoming CE-IVD update set new requirements for validations and verifications. These projects are already complex and burdening, involving a lot of error-prone manual work mainly done in Excel sheets and paper documents.

Due to their high ionic conductivity strontium-substituted lanthanum cobaltites (La1-xSrxCoO3-δ) have potential applications as solid oxide fuel cell cathodes, gas separation membranes or oxygen sensors. In the heavily Sr doped materials, the ionic conductivity obtained from galvanostatic polarization experiments shows a distinct maximum at certain δ values [1]. This behavior at high oxygen non-stoichiometry may be explained by oxygen vacancy ordering thus decreasing the mobility of the vacancies [2].


International trade can be affected by various economic events, including domestic and global developments, such as economic crises, exchange rate volatilities, natural resource explorations, and globalization. In addition, trade uncertainty is an important factor that affects the trade volume of an economy. Recently, trade uncertainty has increased episodically in the world with trade wars between the US and China, and this uncertainty has spilled over to other countries, thereby affecting trade volumes. This study attempts to understand and explain the role of World Trade Uncertainty (WTU) on both export and import in the Turkish economy for the period from 1998:Q1 to 2021:Q4. Therefore, this study utilizes the Autoregressive Distributed Lag (ARDL) bounds test. The research findings presented here reveal that there is a long-run nexus between the variables in both models. The results also show that an increase in WTU negatively affects export, while it has no statistically significant effect on Turkish import for the period examined.


This paper describes the results of the test on a steel-concrete composite slab with truss-typed shear connectors. This composite slab was recently developed. A series of tests were conducted in order to evaluate (1) the strength of shear connector itself; (2) the ultimate strength; and, (3) the fatigue strength and durability of this composite slab under fixed loading point and moving load. For this purpose, push out tests of 39 specimens, flexural ultimate strength tests of 12 specimens, fatigue tests under fixed loading point of one specimen and fatigue tests under moving load of one specimen were executed. The results are detailed herein.

Assistive technologies (ATs) have been found beneficial for persons with intellectual disability in enhancing communication. However, previous research suggests that these technologies are hard to learn and use, and their portability and availability poses challenges. Researchers widely agree that creating novel technologies is crucial to address these limitations. Little research has been done so far on how textile-based technology could support communication and improve AT's availability for those with intellectual disabilities. The aim of this study was to develop concrete user scenarios from initial user stories derived from literature for using textile based alternative and augmentative communication (AAC) technologies in daily life situations for those with intellectual disabilities. We present the flow of scenario development in our multidisciplinary team and two finalized user scenarios that describe people, activities, contexts, and technologies (PACT).
