The research conducted under this award has focused on the study and development of useful chemical reactions initiated via photoinduced electron transfer events. Specifically the research was initiated with a goal of determining whether the energy "harvested" in a photoinduced electron transfer process could be used to selectively break relatively strong carbon-carbon bonds in organic molecules that otherwise might be relatively unreactive. Since most of the photoinduced electron transfer reactions studied involved a single electron transfer event, the reactions invariably involved bond cleavage processes occurring from odd electron radical ions or ion-radical pairs. Our first results, summarized in publications 1-5 (see list below) showed that amines, amino alcohols and related compounds, subjected to photoinduced one-electron oxidation, undergo selective fragmentation at rates rapid enough to compete with return electron transfer within a contact radical ion pair. Importantly, these results showed that both partners in the contact ion-radical pair the oxidized amine and the reduced electron acceptor are essential for rapid reaction. Subsequent work revealed that quite different donor and acceptor substrates could be used in these reactions (publications 6-14). The studies of fragmentation reactions was extended to a series of different substrates and media (publications 14-18, 19-23) and gradually a focus was developed on potential applications. One particularly interesting application was the development of small molecules and polymers containing both a light absorbing acceptor and a fragmentable donor (publications 19,21,24). The polymers constructed in this manner exhibit light induced decomposition and offer some promise as usefbl photodegradable materials. The last few years of the project focused on photoinduced electron transfer fragmentations occuring as chain processes. Thus in a typical situation organic halide acceptors and electron rich pinacols as donors were found to undergo a double fragmentation reaction that in certain cases occurred as an ion-radical chain fragmentation (publications 26,27,3 1). These reactions, particularly those in which donor and acceptor pinacols both can fragment, (publications 3 1 and 32) can result in large amplifications of an initial photoprocess and consequent quantum yields much greater than unity. The possibility that these reactions can be used in dosimetry for both ultraviolet and visible light or for ionizing radiation has been carried out by investigators subsequent to their leaving Rochester.


"Supper with friends. Candles and wonderful food. Suddenly my face is split apart—the bones feel as though they are shattering and the flesh raked aside by red-hot claws. I lean forward, the food falls from my mouth. The guests stare, concerned and appalled. I cannot speak to explain why the tears stream down my face. I cannot even swallow, my own saliva dribbling onto my plate. All I can do is try not to scream. If I look into a mirror I cannot believe that there is no sign of injury, no blood pouring out of my eye."


You should stop skylarking about with those bloody desert mice and try and stop those woody weeds. I could see clear through that paddock in the '60s. Now look at it. That scrub costs us tens of thousands of dollars in lost fodder and it's almost impossible to muster the livestock." That blunt assessment of our research, first offered by a local farmer in Australia's arid rangelands almost seven years ago, raised an irresistible question for us as field ecologists. Why are Australia's (and many others around the world) grasslands becoming woodier? Disciplines Medicine and Health Sciences | Social and Behavioral Sciences Publication Details Gordon, C.

In a previous article by one of the writers, 1 the histopathology of the lesions of vesicular stomatitis was described and mention was made of further studies on this subject, which were in progress at the time. Additional facts have been secured from the later investigations and are herewith presented. The tissues examined consisted of pads from guinea pigs, 18 to 120 hours after inoculation with guinea-pig passage virus of vesicular stomatitis of horses. The pads were fixed in Zenker's fluid (with acetic acid) and stained with eosin-methylene blue. The cells which are most profoundly affected are those in the upper part of the epidermis, that is, just beneath the horny layer. The basal epithelial cells are not as much damaged by this virus as by the virus of herpes. The cells immediately beneath the horny layer are swollen and stain less intensely than normal ones. As degeneration proceeds vesicles form, containing a loose reticulum composed of collapsed degenerated cells. Later there is infiltration with polymorphonuclear and endothelial leucocytes. The cytoplasm of the affected epithelial cells becomes granular. The nuclei swell and finally appear as empty sacs with a dark blue-staining membrane. The nucleoli become first vacuolated and later fragmented. Often they are extruded and enter the cytoplasm, and frequently the staining is pink instead of blue.


This paper presents some improvements that have been made to UNLSumm, an automatic summarizer of UNL Texts. These are texts encoded in the Universal Networking Language (UNL), an artificial language intended to convey conceptualizations of natural language texts. In UNLSumm, a set of heuristics is responsible for, based in the UNL characteristics, prune sentences of a UNL Text, generating its UNL summary. We now present a case study conducted to identify possible bad heuristics and approaches, and also the improvements made to the summarization model based on such a study.


Objective To observe hemodynamic changes of liver in patients with obstructive jaundice. Methods The blood flow in portal vein and hepatic artery were quantitively measured by color Doppler ultrasonography before and after surgery in 20 patients with obstructive jaundice. Results The results showed that the diameter,velocity and quantity of portal vein blood flow before surgery in the patients with obstructive jaundice were significantly lower than after surgery ( P 0.01, P 0.001). The diameter,velocity and quantity of hepatic artery blood flow before surgery in the patients with obstructive jaundice were significantly higher than after surgery ( P 0.001). Conclusion Before and after operation, monitor of liver hemodynamics for these patients are needed. It plays an important role in making clinical therapy schedule.


What would a theatre history course look like without the confines of time? I do not mean a never-ending semester, but a course that moves beyond the assumption that theatre history is a stable, progressive movement of theatrical styles across time; a course that rejects the restrictions of linear temporality and all of the canonized curricular expectations that often envelop it: a theatreorigin story beginning in ancient Greece, the mandatory Shakespeare unit, black artists siloed to a single week, non-Western modes of performance framed as Other, exoticized within even the most recent editions of popular textbooks. What would a theatre history course look like that requires students to interrogate historical "fact" rather than memorize information? Where, at the end of the semester, students leave the classroom with an understanding of how power plays out in the archive, the contingency of historical narratives, and the efficacy of writing and performing as modes that can complicate the legacies of their cultures and communities? Within the structure of Theatre History I and II (or III) curricula, how do theatre and performance studies educators move outside the restrictions of static models of teaching students a wide array of theatrical movements, texts, and cultural contexts?


Several million "at will" employees have been laid off not only from their jobs but their careers. Survivors often lack loyalty to their organizations because downsizing has become an annual rite of headcutting. This guide helps managers and employees meet the challenge of continuous restructuring.


An algorithm to identify and remove term redundancy is proposed for text classifiers using ranking-based feature selection. The proposed method employs a normalized mu- tual information, which is called inclusion measure, to es- timate asymmetric dependency between two terms. Based on pair-wise dependency measures, a dependency matrix is constructed. In this paper, an algorithm is proposed to learn term dependency links from term dependency matrix, and visualize the dependency between term in a graph called term dependency tree. All nodes of the tree are categorized into two groups: hubs and links. Any node whose outde- gree is less than two will join the Links group. We show that all link nodes are most likely redundant. We also in- troduce a criterion, which is called substitution cost, to de- cide whether to remove or retain a candidate, redundant term. The proposed approach is applied to four well-known benchmark data sets with a SVM and Rocchio classifier us- ing a set of highly aggressive feature selection schemes. The results show the effectiveness of the proposed method espe- cially when applied to weak classifiers.


This essay offers a comparative analysis of the ways that Isaac Julien9s Looking for Langston (1989) and Rodney Evans9s Brother to Brother (2005) inscribe Richard Bruce Nugent9s landmark short story "Smoke, Lilies, and Jade" (1926). Both films are examples of how "Smoke," which was first published in the short-lived but infamous journal FIRE!!, now functions as much more than an artifact from the Harlem Renaissance9s dynamic print culture. As I contend through this analysis, "Smoke" is a central diegetic element in both films. It enables Looking9s visual depiction of the sojourn that Nugent9s protagonist Alex has with his male lover "Beauty" and Brother9s depiction of an intergenerational collaboration that honors Nugent as a black gay male artist. Through honorific interpretations of "Smoke, Lilies, and Jade," Looking for Langston and Brother to Brother affirm a black gay print culture as indispensable to black gay film.


Some of the problems and uncertainties of stratospheric–mesospheric modeling are discussed in terms of the variables which constitute the continuity equation. The status of one- and two-dimensional eddy coefficients, required in the evaluation of the flux equation, are briefly reviewed. The production and loss terms are discussed both generally and with respect to the particular uncertainties in the CH4, H2O–HOx, NOx, and O3 chemistries.


The configurations and conformations of S-methyl benzothiohydroxamic acid (3) and its S-oxo and S,S-dioxo derivatives (5) and (7) were established by means of a graphical comparison of their dipole moments with those of the corresponding p-nitro compounds.The proton magnetic resonance and infrared spectra of these compounds were also studied.It is concluded that the relative stability of stereoisomers in the series of compounds C6H5C(NOH)X seems to depend more on the electronic nature of the group X than on its steric requirements.


1. Cerebral blood flow was measured in 17 baboons, anaesthetized with pentobarbitone, paralysed with gallamine and mechanically ventilated and in which the right sinus and both aortic nerves had been cut and the left carotid sinus vascularly isolated. Later in each experiment, the head was artificially perfused with femoral arterial blood via the innominate artery.


In order to improve the situation of straw burning in a large area and achieve sustainable development of agriculture,the influences of different tillage modes and continuous straw returning on soil structure and nutrient content in direct seeding paddy field were researched through field tests.The results revealed that straw returning could significantly reduce soil bulk density,and tillage mode also had an impact on soil bulk density;straw returning could obviously increase the content of organic matter,total nitrogen content in the soil,as well as available phosphorus content in the soil layer of 0~7 cm.Tillage mode could significantly influence the content of organic matter and total nitrogen in the soil as well,but its impact on the content of soil available phosphorus was not significant.


The distributions in the HR diagram with theoretical time-constant loci for stars in several young clusters and superclusters are compared to demonstrate that blue stragglers in these aggregates are most frequently simply single massive (mode B) stars formed in bursts of star formation that occur at discrete intervals in time following the formation of the bulk of the low-mass (mode A) stars in the aggregate. The characteristics of the close binary systems in these aggregates are examined to show that, in several cases, mass transfer by Roche lobe overflow has or will occur and that, in some instances, the system would have appeared as a blue straggler prior to the mass-transfer event, and, in other instances, mass transfer will lead to the identification of the system as a blue straggler. Thus, it is concluded that the blue straggler phenomenon has at least two distinct physical origins: it may originate from delayed formation (starbursts) or from delayed evolution in some close binaries (mass transfer from an evolved primary). 185 references.

An Integrated Approach to Managing Vessel Service in Seaports Efficient vessel service is of utmost importance in the maritime supply chain. When serving a group of incoming vessels, berth allocation and pilotage planning are the two most important decisions made by a seaport. Although they are closely correlated, the berth allocation problem and pilotage planning problem are often solved sequentially, leading to suboptimal or even infeasible solutions for vessel services. In "Vessel Service Planning in Seaports," Wu, Adulyasak, Cordeau, and Wang focus on a vessel service planning problem that optimizes berth allocation and pilotage planning in combination. To solve the joint problem, the authors develop an exact solution method that combines Benders decomposition and column generation within an efficient branch-and-bound framework. They also propose acceleration strategies that significantly improve the performance of the algorithm. Test instances from one of the world's largest seaports are used to validate the effectiveness of the approach and demonstrate the value of integrated planning.


The "Washington consensus" and "shock therapy" approach to transition economies ignored the Keynesian lessons from the Great Depression: that market instability is a possibility and there may be an active role of government in managing stability and growth. The severe output decline in East Europe and the former Soviet Union (EEFSU) was triggered by a simplistic policy of liberalisation and privatisation, which ignored many economic complexities and the existence of multiple equilibria under alternative divisions of labour. Issues of fundamental importance, such as the chain reaction between macroeconomic instability and microeconomic behavior, the role of the government in creating learning space in development, interactions between economic openness, sustainable growth, and social stability, can all be revealed from comparative experiments between China and EEFSU. These include the role and impact of exchange rate regimes, price dynamics, trade policies, and reform strategies. The tremendous cost of the Transition Depression sheds new light on theoretical limitations of atomic demand and supply analysis, theory of hard-budget constraints, microfoundations in macroeconomics, and the property rights school in institutional economics. New development policy based on learning, innovation, and decentralised experiments will pave the way for new thinking in complex economics.


Purpose of the conducted study was to evaluate the possibility of using underutilized seaweed (Sargassum sp.) to encapsulate prebiotics in dairy food applications. This will enable dairy based industries to utilize local materials instead of imports, whereas direct crude exports of the seaweeds can also be consumed for more valued added purposes. For encapsulation purposes, Lactobacillus acidophilus and Bifidobacterium bifidum strains were selected. When considering the surviving ability of the two strains of bacteria in 0.5% bile solution and gastric solution followed by intestinal juice and inclusive and non-inclusive of bile salt, it was evident that the strains coated with Sodium alginate from Sargassum provide a positive protection and therefore is foreseen as a better natural solution for probiotic encapsulation in dairy based food products. Extraction and utilization of local seaweeds in South Asia, has not been an exploited area so far, and therefore this research will form a base to formulate probiotics in local dairy industry by using Sargassum seaweed.

When the author's Memoir on the Conductivity of various substances was presented to the Society, it was intimated to him on the part of the Council of the Society, that it might be advisable to determine absolute instead of relative conductivities, the latter only having been attempted in his previous experiments. It is partly in consequence of this intimation, and partly from the desire to make his former investigations more complete, that the author has given his attention to the construction of a calorimeter which might serve for this purpose. His present memoir contains a description of this instrument, with the results obtained from its application to the surfaces of various substances. The apparatus used by Messrs. Dulong and Petit was more delicate and complete than the simpler instrument devised by the author of this paper, but it was calculated only to determine the radiating powers of substances of which the bulb of a thermometer could be constructed, or with which it could be delicately coated. The only substances to which, in fact, it was applied, were glass and silver, the radiation taking place, in the first case, from the naked bulb of the thermometer, and, in the second, from the same bulb coated with silver paper. In these cases, too, it was the whole heat radiating in a given time from the instrument, and not that which radiated from a given area, that was determined. For this latter purpose the apparatus was not well calculated, on account of the difficulty of obtaining with accuracy the area of the surface from which radiation took place. The instrument here described can be easily applied to any plane radiating surface, while the area of that surface can be easily determined to any required degree of accuracy. The quantity of heat radiating under given conditions, from a unit of surface in a unit of time, can thus be easily ascertained. The paper contains a detailed description of the instrument, and of the experiments made with it.


We investigate the non-linear saturation behavior of a top illuminated double heterostructure p-i-n photodetector under high optical power A two-dimensional drift-diffusion model has been used to determine the influence of the space charge screening effect on the detector bandwidth. The results show that, when increasing the light optical power, the electric field within the intrinsic region begins to decrease. Consequently, the carrier velocity falls while the electron and hole density increases. This phenomenon is cumulative and determines a bandwidth reduction.


On basis of ventilator dimensionless performance curve and specific speed, a ventilator selection software is studied on purpose of improving the efficiency of ventilator selection. Utilizing programming technology, a database is built which consists of ventilator type, performance parameter, outline dimensions, etc. Graphical interface is programmed using C# language and performance curve is generated and analyzed by the block of MATLAB. Mixed programming method is used to integrate the above two different programming tools, which shortens software development cycle. Analysis result shows that the software developed by the authors meets application requirements and the selected ventilator type is qualified to be adopted.

We talk about chances by using sentences such as: The probability that the electron will be detected as having spin up is one over root two. The coin is fair. And we make reference to morals in sentences such as: Murder is wrong We have a duty to rescue those in dire need of assistance. In general, what is the epistemic standing of our beliefs about chance and about morals? While it might seem odd to consider such diverse types of belief together, there are, I believe , important and surprising analogies between them. Our justification for both types of belief is undermined or weakened by plausible hypotheses about the genealogy of those beliefs. While the degree of undermining is different in the two cases, the structural similarity of the arguments are striking, and mutually illuminating – even for readers who remain unpersuaded by one or other of the undermining explanations that I will offer. The epistemology of moral propositions is notoriously murky. We are full of moral opinions, but they have no obvious empirical or a priori justification. The epistemology of chance propositions is – seemingly – in much better standing. Chances are in some important way tied to two empirically observable phenomena: symmetries and frequencies.

Angioleiomyomas are benign mesenchymal tumours commonly occurring in the subcutis of extremities. They are typically composed of interlacing fascicles of smooth muscle cells with intermingling vascular channels. Angioleiomyomas of the uterus are rare and unique variant with only very few case reports available in literature. Herein, we report a case of this rare entity in a 37 yr old female who presented with complaints of urinary retention, dysfunctional uterine bleeding, and abdominal pain at our hospital.


In the last decades, the field of maritime transports has been characterized by an exponential growth in terms of both people and wares moved and/or exchanges. Nevertheless, advancements in employment and business opportunities have not always been accompanied by adequate actions regarding education and training. The result is a scenario characterized by a lack of qualified seafarers in which, in addition, unhomogeneity in competence frameworks, training programs and certification modalities makes mobility across countries an extremely critical task. Such issues have been recently addressed by the O.R.S.A. M.I.NO.R.E. project, whose aim is to develop a reference scenario for the certification of seaman achievements through the use of a shared formal language within a distributed Web based environment relying on smart card technology. In this paper, the preliminary results of this project are discussed, by analyzing the formalization methodology being pursued, and providing the details of the so called electronic European Seaman's Book prototype architecture.


Directly reduced iron (DRI) is a major source of iron units in cases of low scrape availability and/or hot metal. Its main advantage is it is low content of phosphorus and sulphur. Removal of phosphorus and sulphur demands high energy consumption in steel making process.

With fast depleting sources of cooking coal, the availability of hot metal will decrease in the coming years. Also, scrap availability is already on the declining trend. Hence, DRI is going to be the main source of iron units in the future, especially in electric arc furnace (EAF steel making).

The disadvantage of DRI usages lies in it is high reactivity. Freshly produced DRI possesses high susceptibility to oxidation whenever it comes in contact with air. The generated heat in the oxidation reaction increases the tendency to oxidation, thereby, starting a short of chain reaction and ultimately leading to the burning of DRI. This phenomenon makes storage and handling of DRI a concern.

The problem caused loss of one cargo in Delta steel company, Nigeria. The authors of this dissertation were given the responsibility to work out the solution in the minimum possible time for implementing it to the next shipments. It is heartening that the problem could be successfully solved and implemented in the next shipments in November '06. Hence, after above work implementation of the recommendations for a $45 risk/ton of DRI, only $1 is to be spent for protection against the risk.

This paper presents the e-SENSE middleware architecture for distributed processing of context information in dynamic wireless sensor networks. At the lower layer, sensor nodes organize into clusters spontaneously based on shared context. These clusters form the basis for the service-oriented processing layer, where the functionality of the sensor network is expressed using service task graphs supporting distributed execution of applications. The higher layer is responsible for complex context inference and recognition. As a concrete example we evaluate the distributed recognition of human activities in a car assembly process.


Compound 1 coupled smoothly with aromatic diazonium salts to yield the corresponding arylhydrazones 2a-d. Compounds 2a-d condensed with DMF-DMA in refluxing xylene to yield the pyridazinones 3a-d. Compounds 3a-d were also established based on its further reaction with some active methylene reagents and some nucleophilic reagents. So, reactions of 3a, b with malononitrile in refluxing ethanolic piperidine afforded arylidinemalononitrile 4a,b. The pyridazinone derivatives 3a, b reacted with hydrazine hydrate to afford the hydrazine derivatives 5a, b. When 3a,b were fused with hydrazine hydrate without solvent, the pyrazolo[4,3-c]-pyridazines 6a,b were obtained. Compounds 6a, b were also obtained when compounds 5a, b melt over melting point for short time. Condensation of 2a, b with ethyl cyanoacetate yield 7a, b. Similarly, reactions of 2a,b with 1 mole of malononitrile afforded the pyridazine derivatives 8a,b. While, when 2 moles of malononitrile reacted with 2a, b in the same experimental conditions to yield the cinnoline derivative (9a, b). Reactions of pyridazine 8a,b with 1 mole of malononitrile afforded 9. Compound 2b was reacted with a mixture of arylidinemalononitrile and acrylonitrile to yield product formulated as triazole moieties 12a, b. Similarly, compound 2b was reacted with a mixture of maleic anhydride and acrylonitrile in the same above experimental conditions to give 13. Also, reactions of 2b with hydroxylamine hydrochloride yield 14.

The study deals with R&D, international spillovers and productivity growth. More specifically the first issue we look at is whether R&D spillovers are transferred across different industries and countries. The effect of R&D conducted within the industry, as will as in other industries and countries, on productivity growth are examined. The second issue concerns what channels and factors facilitate the knowledge spillovers. Special emphasis is put on examining the effect on knowledge flows from international trade and geographic conditions. Our third and final issue is to examine the effect on productivity growth from knowledge spillovers facilitated through international trade, direct foreign investment (DFI) and geographic conditions.

The mechanism of the interaction of polycrystalline Ag‐Al thin‐film couples to form Ag2Al at temperatures from 107 to 221 °C has been studied. Techniques of film characterization included Rutherford backscattering, x‐ray diffraction, and SEM. The dependence of the interaction on the grain size of the Ag film (660–7500 A) was measured. An effective activation energy of 0.86±0.05 eV was found. The reaction is believed to occur initially by nucleation and growth of Ag2Al grains at Ag grain boundaries at the interface; after formation of a continuous Ag2Al layer, the growth of this layer follows a t1/2 law, controlled by diffusion through the grain boundaries of the Ag2Al layer.


felt necessary at this point. Management comprised topical methylprednisolone aceponate 0.1% ointment, topical xylocaine 5%, oral prednisolone 25 mg daily for 1 week then 12.5 mg daily for a further week and urinary alkaliniser. On review 3 weeks later, the ulcers had nearly all healed and the patient was symptomatically much improved. Ten months later she had reported no lesion recurrence, nor any symptoms suggestive of Behc et's disease, IBD or other systemic illness.

Background: Congenital anomalies are an important cause of neonatal deaths, chronic illness, and disability and are most common in low- and middle-income countries. Central nervous system (CNS) congenital anomalies are one of the most common abnormalities. Information on the burden and types of CNS anomalies will facilitate health system planning and an efficient allocation of scarce resources. We determined the prevalence and pattern of CNS congenital anomalies in a neonatal unit in Jos, north-central Nigeria. Materials and Methods: A retrospective descriptive study of all neonates admitted with CNS congenital anomalies into the neonatal unit of Jos University Teaching Hospital (JUTH) from October 2013 to September 2016 was conducted. Results: One hundred and fifty-five (14.8%) of the 1046 babies admitted during the period had congenital anomalies. Twenty-seven babies (14 males and 13 females) had CNS anomalies giving a prevalence rate of 2.6%. CNS anomalies constituted 17.4% of the 155 babies admitted with congenital anomalies. All 27 (100%) of the babies were born outside the teaching hospital, with 13 (48.2%) of them delivered at home. Neural tube defects (NTDs) were the most common CNS malformations (26; 96.3% of the CNS anomalies). Talipes equinovarus was the most common associated anomaly (6; 22.2% of the babies). Conclusion: The prevalence of CNS anomalies among admitted neonates in the JUTH is high. NTDs were the most common CNS anomalies, with myelomeningocele being the single most common disorder.


In this paper we describe a Bayesian Model Averaging (BMA) methodology developed for detecting artifacts in electroencephalograms (EEGs). The EEGs can be heavily corrupted by cardiac, eye movement, muscle and noise artifacts, so that EEG experts need to automatically detect them with a given level of confidence. In theory, the BMA methodology allows experts to evaluate the confidence in decision making most accurately. However, the non- stationary nature of EEGs makes the use of this methodology difficult. In our experiments with the sleep EEGs, the proposed BMA technique is shown to provide a better performance in terms of predictive accuracy.


Abstract We make five over-time comparisons of student knowledge of civics and government: a) knowledge among 4th, 8th, and 11/12th graders between 1975/6 and 1998 using two separate NAEP trend assessments; b) knowledge over the same period by comparing responses to individual items asked in the 1975/6 and 1981/2 assessments to responses on identical questions asked in the 1988–98 assessments; c) knowledge among 12th graders in the 1930s–1960s compared to 1988–98 using a small set of identical or highly similar items; d) the ability of students in the 1950s–1960s versus 1998 to interpret political cartoons and to read tables and graphs; and e) knowledge of current and past high school students on putative "domains" of civic knowledge. In the two older grades, there has been a decline in civic knowledge in the past quarter century. The decline among 12th graders was small, on the order of several percentage points; yet it may have left high school seniors in 1998 able to answer questions only a little better than 8th graders in the mid–1970s. The long-term comparisons suggest that student skills have improved and, more ambiguously, that contemporary high school seniors are not demonstrably less informed about politics and government than were students in the distant past.


The seasonal pattern and individual variation in reproductive success was studied in a population of the river bullhead, Cottus gobio L. Female fecundity and male reproductive success were correlated with body size. Large males were found to breed early in the season when most of the large females spawned. The diameter of eggs found in male nests indicates that females tend to mate with males larger than themselves. The analysis of stomach contents suggests that guarding males cannibalize some of their own eggs. During parental care, the rate of filial cannibalism increases as guarding male body condition deteriorates.


The railway industry throughout the world continues to emphasize the importance of developing innovative trackbed design technologies for both heavy tonnage freight lines and high-speed passenger lines. The purposes are to achieve high levels of track geometric standards for safe and efficient train operations while minimizing long-term track maintenance costs and extending track component service lives. During the past several decades designs incorporating a layer of asphalt (or bituminous) paving material, similar to a highway pavement asphalt base layer, as a portion of the railway track support structure have steadily increased until it is becoming a common or standard practice. This technology has demonstrated applications for the construction of numerous new high-speed passenger lines in Europe and Asia. This paper reviewed the development of asphalt used in railway engineering.


The presence of nonadiabaticity in the photodetachment bands of the anionic mixed carbon-boron cluster C3B5- has been realized through ab initio electronic structure calculations and detailed analyses of quantum dynamics study on top of those electronic structures. In the course of our study, we traverse extensive first principles electronic structure calculations to compute potential energy curves and to trace the energetic locations for the conical intersections in the multidimensional surfaces. All the ab initio calculations are performed on the four low-lying electronic states of the C3B5 cluster, while quantum nuclear dynamics are pursued on those electronic states by applying both time-dependent and time-independent quantum chemistry frameworks. In particular, we rely on the diabatic electronic representation to construct the molecular Hamiltonian. Altogether, the simulated theoretical spectra offer exceptional agreement with the experimental attainments.


Abstract This article examines how James Alderson blew the whistle on the fraudulent Medicare practices of one of America largest hospital conglomerates, Columbia/HCA, and its former subsidiary, Quorum. Also discussed is how Alderson maintained his ethical autonomy in the face of organizational conformity. Relevant literature contributes to an understanding of the lessons that can be learned from such an exemplar.


Covalent organic frameworks (COFs) have permanent, nanometer‐scale pores endowed with high porosity and thermal and chemical stability, which is widely used as composite membranes and applied in the field of separation. Conventional methods for preparing composite membranes, such as spray coating, spin coating, and pressure‐assisted or vacuum‐assisted filtration, have problems such as the selective layer can easily fall off. Here, an integrated casting–precipitation–evaporation method is proposed to prepare flexible COF composite membranes (DPBI/HTpBD). The DPBI/HTpBD composite membranes constructed with hollow spherical shell COF selective layer (HTpBD) and porous supporting layer are designed and applied in a vanadium flow battery. The excellent coulombic efficiency (CE, 99.5%) and voltage efficiency (VE, 81.1%) of batteries (180 mA cm−2) are achieved by the nanometre‐scale pores of the hollow spherical shell COF selective layer. In addition, the rigid pore structure inside COF bonded by covalent bonds endows the DPBI/HTpBD composite membranes with outstandingly high temperature stability. Compared to that of the Nafion 212 and DPBI pristine membranes (CE reduces by 5.2%, 3.3%), the CE of DPBI/HTpBD‐9 composite membrane‐based cell only reduces by 0.9% as the temperature increases from 25 to 55 °C. This work provides a new preparation method for high ion‐selective and high temperature stable battery membranes.


In early 2009, immediately following the end of the WR140 periastron campaign (see these proceedings), I turned my telescope back to epsilon Aurigae in time for the start of the eclipse. As well as being an interesting object in its own right, the Pro-Am campaign being run on epsilon Aurigae during the current eclipse is a good example of how amateur spectroscopists can make a useful contribution. epsilon Aurigae is a naked eye magnitude 3 star and was first noted to be variable by Johan Frisch in 1821. It was subsequently found to be an eclipsing binary with a period of 27.1 years which undergoes an approximately 2 year long flat-bottomed eclipse with approximately 0.8 magnitude drop in V.


The utility model discloses a lens mechanism with stable and automatic focusing function, which comprises a shell, a motor, a first gear wheel, a second gear wheel, a lens module and an elastic component. The motor is arranged inside the shell; the first gear wheel is arranged inside the shell and fastened on the axle of the motor; the second gear wheel is also arranged inside the shell and vertically meshed with the first gear wheel; a helical inclined plane is provided on the upper surface of the second gear wheel; the lens module is arranged inside the shell and provided with a convex block which contacts with the helical inclined plane of the second gear wheel; the elastic component is arranged between the shell and the lens module. Therefore, by the direct contact between the convex block and the helical inclined plane, the utility model can reduce the overall size and the lens module can reach precise positioning.


Scheduling all-to-al connections in a network of limited physical connectivity provides a way to trade bandwidth for reduced routing control as well as deterministic connection latency. In this paper, we consider the problem of scheduling all-to-all connections in a WDM ring. For a given number of wavelengths, K, and a given number of transmitter/receiver pairs per node, T, we determine the theoretical lower bound (TLB) on the scheduling length. A basic scheduling strategy called complementary assembly with dual strides (CADS) is proposed. In a special case when K equals 1 and T equals 1, the TLB can be achieved based on CADS. Heuristic algorithms based on either homogeneous or heterogeneous CADS are then proposed for the case when K > 1, and near minimum scheduling length can be achieved for any T. Our analysis also indicate that there is an optimal value of T for a given K such that neither T nor K would become the performance bottleneck. Impact of wavelength-tuning delay, ring propagation delay, laser array fabrication especially wavelength drift of the WDM sources on the scheduling method is also discussed.


Introduction Endothelial function is impaired in adults with sickle cell anaemia (SCA), but limited data exists in children. Endothelial damage occurs from chronic inflammation, oxidant damage, immune cell activation and ischemia-reperfusion injury. In addition, availability of nitric oxide (NO) as the major vasodilator may be reduced as a result of scavenging by plasma haemoglobin and reduced arginine substrate for endothelial nitric oxide synthase. Methods Tanzanian children (N=119) with SCA (HbSS) aged 8-11.9 years enrolled in the Vascular Function Intervention Trial (ISRCTN74331412/NCT01718054) underwent baseline assessment of endothelium-dependent and -independent vasodilatation. All children were determined clinically well at assessment, hydroxyurea naive, on no long-term medication and not receiving chronic blood transfusions. Blood pressure and vasomotion were assessed after 10 minutes recumbent rest in a temperature controlled room between 08-13:00 hrs. An identical protocol as published in children (Donald & Charakida et al. Eur Heart J; 2010: 31; 1502-10) was used. In brief, brachial arterial endothelium dependent dilatation was assessed by 1 of 3 trained technicians using ultrasound imaging (Ultrasonix SonixTouch with a 12Mz probe & stereotactic holder) to assess flow-mediated dilatation (FMD) in response to reactive hyperaemia induced after release of transient blood pressure cuff occlusion (5 min, 200 mmHg, Hokanson, USA) using an automated air regulator (Logan Research, UK). Automated B-mode image edge detection was used to measure maximum change in arterial diameter (Brachial Tools) expressed as a percentage of resting baseline diameter (FMDmax). Endothelium-independent responses to 2.5µg sub-lingual glyceryl-trinitrate (GTN) were also assessed. All recordings were over-read by an experienced researcher in the UK. Venepuncture for full blood count, clinical chemistry and amino acids was conducted after FMD assessment. Results Patient characteristics are described in Table 1. Mean brachial artery diameter at baseline was 2.61mm (95% CI 2.55 – 2.67mm). Mean FMDmax was 7.70% (95% CI 7.09 – 8.32%). Endothelium-independent vasodilation (GTNmax) was 4.15% (95% CI 3.83 – 4.47%). The FMDmax response was on greater than the GTNmax response (Figure 1). No effect of room or skin temperature on FMDmax or GTNmax was observed. There was a strong inverse association between baseline artery diameter and FMDmax (-3.46, P Discussion We have characterised peripheral vascular function in a large cohort of children with SCA. Mean FMDmax was slightly lower than that observed in predominantly Caucasian non-SCA British children of similar age (8.1% [SD3.4]) (Donald & Charakida et al. Eur Heart J 2010: 31; 1502-10), but higher than reported in 21 older French children with SCA (5.6 +/- 0.2) (Montalembert et al. Haematol 2007: 92; 1709-10) which might reflect deterioration of endothelial function with age. There was no apparent association between FMDmax and hemolytic markers or with nutritional status at baseline. Recruitment and assessment of appropriate local non-SCA controls for comparison is planned. Amino acid analyses are ongoing. Disclosures: No relevant conflicts of interest to declare.


Abstract: Background Traditional psychotherapeutic interventions show small to moderate effect in treating psychotic symptoms. Virtual reality (VR) assisted treatments has the potential of advancing current psychotherapies for psychotic symptoms by creating virtual environments that can elicit responses (e.g., thoughts, feelings, behaviours) mirroring real-world settings. This presentation will highlight the current research initiatives using virtual reality-based interventions targeting positive and negative symptoms in patients with psychosis. Results Main findings from the pilot-studies and randomized clinical trials on computer-based and immersive VR-interventions demonstrate preliminary evidence of VR-based psychotherapy for treating auditory hallucinations and paranoia with large effect sizes (Cohens d= 0.75-0.80). Additionally, pilot data has provided indications as to VR-psychotherapy being feasible and acceptable in treating negative symptoms and may have a large effect on participants achieving their goals and potentially in reducing negative symptoms. No adverse effect has been found related to the VR-interventions. Discussion The promising findings on VR-based interventions for psychosis calls for large-scale randomized clinical trials consolidating the evidence for the effect in treating positive and negative symptoms in psychotic disorders. Cost-effectiveness of these short-term VR-based interventions are essential to inform scalability and implementation. Finally, most of the studies target patients in more chronic/treatment resistant phases of psychosis highlighting the need to investigating the effect in earlier phases of psychosis, that is, first-episode and potentially clinical high-risk states.

This paper examined the various electronic learning platforms adopted by undergraduates in Nigerian Universities which include both private and public universities in Nigeria and its related challenges during the COVID-19 lockdown in 2020. The coronavirus' enormous consequences, which affected all countries and industries, influenced around 91% of the world's students. The objective of this study is to investigate the experiences of private and public university undergraduates in a Nigerian University, to determine whether there is a significant disparity in the accessibility, affordability, and ease of use of the various e-learning platforms that were adopted during the global pandemic lockdown. The study employed the survey method in eliciting useful information from undergraduates in Covenant University, and in the University of Lagos. The population of the study consisted of 374 undergraduates from both schools. Due to the inaccessibility of students whose lecturers were on industrial action by the Academic Staff Union of Universities, the questionnaire was physically distributed to students at Covenant University, while a Google form was generated for students at the University of Lagos. Data was analyzed using descriptive techniques in frequencies, percentages, and linear regression analysis. Results from the study revealed that 68.1% of students at Covenant University utilized more e-learning platforms like Moodle, Coursera, Zoom, and WebEx unlike their counterparts at the University of Lagos who used only Moodle and Zoom with 43.6%. Also, 87.5% of Covenant University undergraduates made use of their laptops mostly for their e-learning classes while 56.4% of their counterparts in the University of Lagos mostly made use of their smartphones. Findings revealed that students from public Universities faced major challenges such as unstable internet, limited financial capability in buying devices such as laptops, and lack of skill and competence in navigating the e-learning platforms while students in the private universities on the contrary had relatively stable internet connectivity, could afford laptops and smart devices and had the requisite skills to properly navigate their e-learning platforms. The study concludes by recommending the provision of substantial financing that will aid in the acquisition of relevant technology to promote and support e-learning in public universities in Nigeria. It also suggested the inclusion of public University students with adequate training on how to navigate the e-learning platforms, thereby equipping them with the requisite skills needed to maximize the benefits of e-learning. The study emphasizes how the use of e-learning can be an effective sustainable learning solution for current and future situations by the main actors, educators, and learners. In the long run, the Nigerian educational system would be better prepared to face future emergencies that may warrant the adoption of remote learning.


Under the sponsorship of the U.S. Department of Energy's Office of Classification (DOE/OC), Brookhaven National Laboratory/Technical Support Organization (BNL/TSO) has prepared a level-three interactive-laserdisc program for the training of authorized classifiers in the Department of Energy. This training programs consists of six modules presented in several formats. The material is presented in a highly interactive manner with various tests to reinforce and evaluate the trainee's progress in learning the material. A lengthy qualification test is presented at the end of the educational material. The various instructional techniques of scenario presentation, ''talking heads'', graphics, textual material and combinations of the above are used to assure that the training material attracts the trainee's interests and motivates him to understand and use the material. The state-of-the-art interactive laser videodisc with its storage capacity, speed flexibility, and superior training capacity was the logical choice for the training of Authorized Classifiers in the Department of Energy.


E ver since the decision by Morningstar to classify domestic equity mutual funds into one of nine style categories, financial advisers have often been faced with the task of assessing the risk-return characteristics of these equity styles. The nine categories are the intersection of three size classes (large, midcap, and small), and three valuation classes (value, blend, and growth). Investment advisers are perhaps familiar with the historic evidence that portfolios of small companies tend to have higher long-term average returns but also higher volatility than portfolios of large companies. However, the performance of so-called "value" stocks (often defined as companies with high book-to-market ratios) versus "growth" stocks (generally defined as low book-tomarket ratios) is less known and more controversial. The purpose of this paper is to explore in depth the risk-return characteristics of value and growth portfolios. In particular, we focus on the possibility of average returns and risk changing over time. Thus the central questions in this study are: • Does value investing still result in higher average returns than growth investing? Additionally, is the relative performance stable throughout time? • Is value investing riskier than growth investing? Is the relative risk stable throughout time? • In the event of a significant down stock market, which investment style offers the most down-side protection? By examining the historic behavior of these investing styles, it is possible to obtain a better sense of the magnitude and stability of each style's risk and returns. This, in turn, will help investment advisers better match the investment style to their clients.


The highly nonlinear, stochastic nature of photovoltaic (PV) systems impose difficulty in modeling and control design. The controller is employed to efficiently adjust the operating point decided by maximum power point tracking (MPPT) algorithm instead of directly controlling the duty cycle of the DC-DC converters linked to PV system. This paper proposes a linear quadratic regulator (LQR) based tuned PID controller for PV voltage control for a PV system interfaced with a boost converter topology. The proposed model-based controller design is validated through simulation with corresponding stability and robustness check.


Antibody drug conjugates (ADCs), as potent pharmaceutical trojan horses for cancer treatment, provide superior efficacy and specific targeting along with low risk of adverse reactions compared to traditional chemotherapeutics. In fact, the development of these agents combine the selective targeting capability of monoclonal antibody (mAb) with high cytotoxicity of chemotherapeutics for controling the neoplastic mass growth. Different ADCs (more than 60 ADCs) in preclinical and clinical trials were introduced in this novel pharmaceutical field. Various design-based factors must be taken into account for improving the functionality of ADC technology, including selection of appropriate target antigen and high binding affinity of fragment (miniaturized ADCs) or full mAbs (prefentially use of humanized or fully human antibodies compared to murine and chimeric ones), use of bispecific antibodies for dual targeting effect, linker engineering and conjugation method efficacy to obtain more controlled drug to antibody ratio (DAR). Challenging issues affecting therapeutic efficacy and safety of ADCs, including bystander effect, on- and off-target toxicities, multi drug resistance (MDR) are also addressed. 4 FDA-approved ADCs in the market, including ADCETRIS®, MYLOTARG®, BESPONSA®, KADCYLA®. Goal of current review is to evaluate the key parameters affecting ADCs development.


In this paper we propose a real-time method for discrimination of ventricular ectopic and normal beats in the electrocardiogram (ECG). The heartbeat waveforms were evaluated within a fixed-length window around the fiducial points (100 ms before, 100 ms after) after being normalized. Our algorithm was designed to operate with no expert assistance; the operator is not required to initially select any known beat templates which makes it applicable in real-time. It is based on the dominancy of normal beats during the first several seconds for most of records which mostly match the real cases. In addition to R-R intervals, we extract other features as beat width, P wave existence for each beat. Also we apply template matching between the learned template and the unknown beat where template beats are created for each beat shape on runtime. Template matching not only classifies normal dominant beat but also multi-form ventricular ectopic beats where each form is classified separately so as doctors and medical stuff could take the better decision. Our proposed algorithm was tested on MIT-BIH ECG database records with normal and ventricular ectopic beat classes defined in AAMI standard while other records are excluded. Our results show 97.24% overall accuracy with 98.93% and 94.54% sensitivities for normal and ventricular ectopic beats respectively.

Neural operators have been applied in various scientific fields, such as solving parametric partial differential equations, dynamical systems with control, and inverse problems. However, challenges arise when dealing with input functions that exhibit heterogeneous properties, requiring multiple sensors to handle functions with minimal regularity. To address this issue, discretization-invariant neural operators have been used, allowing the sampling of diverse input functions with different sensor locations. However, existing frameworks still require an equal number of sensors for all functions. In our study, we propose a novel distributed approach to further relax the discretization requirements and solve the heterogeneous dataset challenges. Our method involves partitioning the input function space and processing individual input functions using independent and separate neural networks. A centralized neural network is used to handle shared information across all output functions. This distributed methodology reduces the number of gradient descent back-propagation steps, improving efficiency while maintaining accuracy. We demonstrate that the corresponding neural network is a universal approximator of continuous nonlinear operators and present four numerical examples to validate its performance.


ABSTRACTIn this document, allocation of different types of vehicles for transporting products from a manufacturing firm to its depots is considered. The problem involves a limited number of vehicles of various capacities, with the fixed and variable costs as well as a discount mechanism. The objective is defined as the minimisation of the total transportation costs. A mathematical model in the form of nonlinear integer programming is developed and converted to the linear zero-one programme. Due to the NP hard complexity of the proposed mathematical model, a Prufer-based genetic algorithm capable of solving large instances is developed. The efficiency of the proposed algorithm is compared with the solution obtained by CPLEX and the results are reported. The results reveal that the proposed algorithm is capable of providing astonishing solutions with the minimum computational effort.


This paper discusses the use of wide bandgap devices (SiC-MOSFET) in the design of a push-pull inverter which provides inexpensive low power dc-ac inverters. The parameters used were 1200V SiC MOSFET(C2M0040120D) made by power company ROHM. This modeling was created using parameters that were provided from a device datasheet. The spice model is provided by this company to study the effect of adding this component on push-pull inverter ordinary circuit and compared results between SiC MOSFET and silicon MOSFET (IRFP260M). The results focused on Vout and Vmos stability as well as on output power and MOSFET power loss because it is a very crucial aspect on DC-AC inverter design. These results are done using the National Instrument simulation program (Multisim 14). It was found that power loss is better in the 12 and 15 vdc inverter. The Vout in the SIC MOSFET circuit shows more stability in the high current low resistance load in comparison to the Silicon MOSFET circuit and this will improve the overall performance of the circuit.


As is well known, the work of Manuel Puig has been greatly influenced by the cinema. Critical literature has often noted the debt of Puig to the work of certain actresses as well as to Alfred Hitchcock and, less frequently, to Jacques Tourneur, a director for Val Lewton; but less work has been done on the nature of his indebtedness to Josef von Sternberg, Ernst Lubitsch, and Fritz Lang. Puig has said that "Even when writing I think of Lubitsch lightness, or von Sternberg fog curtain laces-lace curtains [sic]" (Katz, Symposium 11). The influence of von Sternberg is indeed striking. The decor of much of the narrative depicting the life of El Ama (The Mistress) in Pubis Angelical, with its mystery and baroque or rococo intricacy in visuals, is quite like the ambience of a film such as The Scarlet Empress (1934). The von Sternberg atmosphere also contributes substantially to certain parts of The Buenos Aires Affair. One would naturally expect the resemblance of the section with a heading from Dishonored (1931) (173-89) to be extensive in visual terms to the film. Puig does appear to set up an equivalence to the visual texture of the movie by his allusions to the "Forest Murmurs" sequence, from Siegfried (183-89). The visuals are also notably reminiscent of the two-part Lang film Die Nibelungen (1924). Dishonored contains repeated visual references to forest or nature motifs, a form of the locus amoenus trope (or, in the terms of Northrop Frye, "the green world"). The room of X-27, the spy played by Dietrich, has flowers embroidered on the drapes; the Colonel's study has a painting of a medieval knight on horseback; again, in a scene in which Warner Oland gets grapes for himself and X-27, an equestrian painting is shown; X-27 wears flowers in the bar; and the room where the Russian spy is interrogated contains mounted stag antlers. The importance of von Sternberg to Puig does not just encompass the visual style of the director. At least as important to Puig is his treatment of Dietrich as a star figure, a process during which, as Herman G. Weinberg notes, writing of the Pygmalion-Galatea relationship between von Sternberg and Dietrich, the director "developed" her from an unknown into one of the great myths of Hollywood (see Josef 51, 79-89). Similarly, some of Puig's characters try to create or to imagine an ideal woman. A very striking instance of such activity occurs in Pubis Angelical with the coercive treatment meted out to El Ama,' a Hedy Lamarr-like actress whose life is strictly governed by her producer so that she may become a famous Hollywood star. The situation of El Ama reads like the negative commentaries sometimes leveled at von Sternberg for allegedly reducing his star to little more than a puppet. Gladys, in The Buenos Aires Affair, fits the pattern of El Ama, at least during the earlier part of her life with her parents. In this regard, the choice of Mildred Pierce (1945) as a film epigraph to one of the chapters in The Buenos Aires Affair is illuminative.2 Puig expands on the degree of control exercised by Veda's parents in the film on their daughter. In the film, Mildred wants Veda to be graceful, to play piano, and to attend finishing school, a plan which Veda seems perfectly willing to follow; Veda's father believes that she should play and be athletic. In The Buenos Aires Affair, both parents try to mold Gladys. Gladys, attempting to escape from the perverse domination of her mother Clara Evelia (Maldonado 136). eventually falls into a worse situation with Leo Druscovich; gradually, however, she finds her way to some sort of emotional freedom. Similarly, one of the characters in Kiss of the Spicier Woman-in one of the films narrated in that novel-liees from domination. Unlike Gladys, she loses her happiness through her rebellion. The unfortunate character is a beautiful chorine who flees from a great "magnate" with her lover. She is not only following her lover but is also trying to escape the kind of smothering cultivation by the magnate that is apparently feared by Amy Jolly (Dietrich) in Morocco (1930) at the hands of the wealthy and elegant La Bessiere (Adolphe Menjou). …


A detector module allowing individual crystal identification without analog coding is proposed. The basic cell is made of a 2/spl times/2 array of scintillators having different decay times that can be identified by pulse shape discrimination. A 16 pixel module consisting of a 2/spl times/2 array of these quad scintillator cells coupled to a 2/spl times/2 avalanche photodiode (APD) array was assembled and tested. In this design, the signal-to-noise ratio can be optimized in two ways: (a) the electronic noise in individual APD channels is minimized by avoiding light sharing between photodetectors; (b) light collection efficiency is improved by eliminating light septa within cells to allow scintillation light propagation across crystals. All four crystals in a BGO/LSO/YSO/CsI(T1) assembly can be clearly separated and individually gated for energy. An energy resolution better than 13% can be obtained in all pixels for 511 keV gamma-rays.

Case Report: A 63-year-old man with hypertension and coronary artery disease treated with multiple stents implantation (three drug eluting stents in Cx, two in right coronary artery (RCA) and one in left anterior descending artery (LAD)) was directed to control echocardiography. Five-chamber apical view during TTE revealed the bright echo of the stent implanted to Cx which seemed to cross the aorta perpendicularly to aortic long axis suggesting retroaortic course of the coronary artery (TTE; Fig. 1; movie clip S1). In TEE long-axis aortic view, we observed cross section of retroaortically coursing Cx with hyperechogenic stent forming "bleb sign" in mitroaortic angle (TEE; Fig. 2; movie clip S2, S3). Three-dimensional (3D) imaging of mitroaortic continuity facing the ostium of left atrial appendage revealed the bulging of endothelium covering stented Cx artery (3DTEE; Fig. 3; movie clip S4). TEE with color Doppler documented the laminar flow in proximal part of solitary ostium of LAD and RCA (movie clip S5). RCA with anomalous Cx origin from its proximal part was found during angiography and angioplasty with stents implantation to both coronaries was performed (angiography; Fig. 4). Despite "bleb sign" may be observed in native arteries, implanted stents in presented patient made anomalous Cx hyperechogenic and easily noticed. Although the described anomaly is often


The creation of an autonomous legal system within the Emirate of Dubai has led to an overlap in the jurisdiction of the two sets of courts, with conflicts of jurisdiction becoming a recurring issue since the establishment of the DIFC Courts in 2004. The DIFC Courts have, through their judgments, interpreted the scope of their jurisdiction widely, perhaps most notably in the Corinth Pipeworks, Bank Sarasin and DNB Bank cases.


Abstract The extent and factors influencing sorption of plutonium (Pu) in shale media have been studied in batch-type experiments. The equilibrium time and isotherm of Pu sorption have been firstly determined. The effect of shale grain size, aqueous pH, water/solid ratio, co-existing ions (cations and anions) and temperature were studied as the factors likely to influence Pu sorption. The experimental variables included the following: grain sizes in five ranges, 0.12 to 0.15 mm, 0.15 to 0.18 mm, 0.18 to 0.25 mm, 0.25 to 0.38 mm, and 0.38 to 0.83 mm; solution pH values of 4, 6, 8, and 10; water/solid ratios of 10:0.25, 10:0.5, 10:0.75, and 10:1; temperatures of 20 °C, 40 °C, and 60 °C); and selected co-existing conventional cations including Na+, Fe+, Al3+, Ca2+, and K+ and anions including SO42-, CO32-, NO3-, and Cl- in each case in solutions of the same total ionic strength. The experimental results demonstrate that the equilibrium time of Pu sorption is 9 d, that the sorption behavior of Pu in the solution is well described by the Freundlich sorption isotherm (Cs=kCeqN), and that Pu is strongly sorbed on shale media. The extent of Pu sorption increased with decreasing grain size, apparently in response to the increase in specific surface area and total pore volume. The results also show that Pu sorption increases with increasing solution pH and with increasing water/solid ratio. The influence of co-existing anions on Pu sorption was much stronger, under the same conditions, than that of the cations; this was attributed to Pu complexation in solution, i.e., the complexing apparently weakened the sorption of Pu on shale particles in the solution. Finally, the influence of varying temperature on Pu sorption is found to be less important than that of other factors, but should never be ignored.


Mesenchymal tumors originating from the wall of the gastrointestinal tract have contributed to fascinating literature worldwide regarding their controversial histogenesis. Most common mesenchymal tumor arising in the gastrointestinal tract is gastrointestinal stromal tumor (GIST). (1,2) Apart from gastrointestinal tract, GISTs that involve omentum, mesentery and retroperitoneum are commonly known as extra gastrointestinal stromal tumors (EGISTs) Though there are many studies regarding various aspects of GISTs, yet primary EGISTs literature are limited. EGISTs are often included in large studies of stromal tumors, in which they account for less than 10% of overall cases. In most cases a preoperative diagnosis is not possible, and the patient undergoes a surgical operation for the generic diagnosis of "abdominal mass". Here were report two rare presentations in the form of non exophytic intraluminal GIST and huge EGIST.


In this paper, a simulation and measurement return loss parameter results comparison in frequency reconfigurable antenna is proposed. More lowprofile and compact microstrip antennas have been developed in recent years for 5 GHz, 5G, WLAN, Wi-Fi, and ISM band applications. These antenna frequency bands may be single, dual, or multiband. The small microstrip antenna, without connecting any external devices like switches, resonators, and passive elements, does not show any variations in their simulation and measurement results like return loss (S11 parameter), gain, and efficiency. However, in the S11 parameter most frequency reconfigurable antennas show a mismatch between simulation and measurement results. The reason for this mismatch between the simulation and measurement results are given in the paper.


The learning environment has several significant influences on the education process. It affects students' motivation, attention and active participation, student-teacher interaction, and lesson plan. In that sense, classroom design is a critical concern to improve the quality of education. Classroom design has many parameters that should be taken into consideration simultaneously. A holistic perspective on all parameters and a systematic process is required to increase the quality of the design. This study aims to guide designers, eliminate mistakes, and improve the quality of classroom design by scrutinizing the required data and suggesting a methodology for the design process. The study focuses on the design of K12 classrooms in Turkey. Design inputs, requirements, and restrictions of K12 classroom design are investigated by using both universal and local resources. Collected data is categorized into four main groups which are, ergonomic needs of the students, organization of the classroom, optimum indoor quality requirements for the learning environment, and regulations of the Ministry of National Education of Turkey. A design methodology that covers the collected data in a holistic and systematic way is defined by applying lean thinking methods. It is an inductive methodology that starts from the smallest unit of the classroom, which is a desk and finalizes with the form and openings of the classroom. Also, an inquiry is suggested to evaluate design correctness. The study is concluded with exemplary drawings that depict the output of the data and the suggested methodology.

During June 1984, while on a field trip to Man Head Cay, concentrations of abundant pottery sherds were observed at several surface locations near the southern end of the cay. This prompted the authors to visit the site several more times to take measurements and make a preliminary survey of the area. The results of this survey are contained in this report. Potsherds had preciously been noted on Man Head Cay before this date (Rose 1982); however, no detailed study had yet been undertaken. The scope of this study was to focus on those details of this site which can be noted from surface analysis, especially pertaining to chronology, ceramic and other artifacts, and subsistence analysis. No excavations have been made at the site; however, a natural "blowout" are create by wind blown removal of sand along the southeastern edge of the cay ha resulted in a natural excavation. Potsherds, shells, and other materials have become concentrated at the surface in this area due to scouring and removal of sand by prevailing winds from the east and southeast (Plate 1).


HIV‐associated neurocognitive disorders affecting greater than 30% of patients are caused by HIV‐1 infection of the CNS, and in part, include neurotoxic effects of the viral transactivator of transcription, Tat protein. In addition to increasing the risk for becoming HIV infected, cocaine abuse enhances the neuropathogenic impacts of HIV‐1. To investigate the outcome of Tat and cocaine interference in the hippocampal neuronal network, cross‐rank‐corrlation was employed to develop a systematic framework to assess hippocampal neurons behavior cultured on multielectrode arrays. Tat and cocaine differentially disturbed neuronal spiking rates, amplitude, synchronous activity, and oscillations within the hippocampal neuronal network via potentiation of inhibitory neurotransmission. The Tat‐mediated impairment of neuronal spiking was reversible by removal of Tat, which restored neuronal activity. The presence of astrocytes co‐cultured with neuronal networks diminished the effects of Tat and cocaine on neuron function suggesting a role for astrocytes in stabilizing neuronal behavior and increasing neuronal spontaneous activities such as bursting amplitude, frequency, and wave propagation rate. Taken together, our studies indicate that the HIV protein Tat and cocaine impair hippocampal neuronal network functioning and that the presence of astrocytes alleviates network dysfunction pointing to a newly discovered pathway through which ionic homeostasis is maintained by neuron‐glial crosstalk in the CNS.


The effect of water on the viscosity behavior of polyacrylonitrile solutions was investigated by a digital rotational viscometer. In the study, the zero-shear viscosity was used to describe the viscosity properties in order to exclude the effect of shear rate. From the study, the zero-shear viscosity of the polyacrylonitrile solution initially decreases with the increase of water content, then increases when the water content is increased above 5 wt%. The phenomenon can be attributed to the competitive processes of polyacrylonitrile chains contraction and intermolecular aggregation.

Protein inclusions are associated with a diverse group of human diseases ranging from localized neurological disorders through to systemic non‐neuropathic diseases. Here, we present evidence that the formation of intranuclear inclusions is a key event in cataract formation involving altered γ‐crystallins that are un likely to adopt their native fold. In three different inherited murine cataracts involving this type of γ‐crystallin mutation, large inclusions containing the altered γ‐crystallins were found in the nuclei of the primary lens fibre cells. Their formation preceded not only the first gross morphological changes in the lens, but also the first signs of cataract. The inclusions contained filamentous material that could be stained with the amyloid‐detecting dye, Congo red. In vitro, recombinant mutant γB‐crystallin readily formed amyloid fibrils under physiological buffer conditions, unlike wild‐type protein. These data suggest that this type of cataract is caused by a mechanism involving the nuclear targeting and deposition of amyloid‐like inclusions. The mutant γ‐crystallins initially disrupt nuclear function, but then this progresses to a full cataract phenotype.


Abstract. Existing vegetation radiative transfer models seldom consider the effects of rice panicles on canopy spectrum. An ear-leaf model was established by adding a rice ear module to 4SAIL-RowCrop model. The geometrical optical model of the rice panicle was developed by assuming that the rice panicle is an upright cylinder. The rice panicle component was considered to be part of the canopy, and seven rice canopy scene components were defined including canopy without ear, the first and second kind of sunlit soil, the first and second kind of shaded soil, sunlit ear, and shaded ear. Thus, the directional radiation of the spike layer was described using the geometrical optical model. Reflectance and transmittance of the rice canopy were calculated using the 4SAIL model. The reflection and radiation characteristics of the soil layer were modeled using 4SAIL-RowCrop. Then, the row-sowed rice canopy scene reflectance was simulated by iterating reflectivity of the seven components in proportion. The ear-leaf model has good simulation accuracy for forward and backward reflectance with the mean R2, relative root mean square error, and RE values between the simulated and measured spectra of typical bands of 0.91, 19%, and 10%, respectively. Thus, the ear-leaf model provides a more technical support for the simulation of canopy reflectance and retrieval of growth parameters in rice.


This paper begins by summarizing the last stages of the debate between Paul Ricœur and Hayden White on the subject of reality writing. It then depicts a history of the bonds between history and literary genres, and considers the writing of an "undisciplined" history interacting with emotions. Indeed, emotional language does not allow for demarcation between fiction and non-fiction literature. The paper also describes the present connection between literary theory and history via the New Historicism and the "corporeal narratology " project. The conclusion considers emerging textual worlds: the digital age predicts new types of reality and fictional writing, which will have to come to terms with the virtual.


This paper analyses the importance of competitiveness factors in international competitiveness ranking of South Africa. In particular, the paper investigates the odds in favour of an improved, as opposed to a deteriorated, Overall international competitiveness ranking due to a change in selected competitiveness factors. The results show that the autonomous improvement in Overall international competitiveness ranking is statistically insignificant while the effect of a change in Government efficiency also has a statistically insignificant effect on the odds in favour of an improved Overall international competitiveness ranking. The results further show that a change in Economic performance, Business efficiency and Infrastructure increase the odds in favour of an improved Overall international competitiveness ranking. Finally, a change in Infrastructure has the biggest odds in favour of an improvement in Overall international competitiveness ranking compared to a change in Economic performance and Business efficiency.


Androgen and androgen receptor (AR) play important roles in spermatogenesis, yet detailed androgen/AR signals in Sertoli cells remain unclear. To identify AR target genes in Sertoli cells, we analyzed the gene expression profiles of testis between mice lacking AR in Sertoli cells (S-AR) and their littermate wild-type (WT) mice. Digital gene expression analysis identified 2,276 genes downregulated and 2,865 genes upregulated in the S-AR mice testis compared to WT ones. To further nail down the difference within Sertoli cells, we first constructed Sertoli cell line TM4 with stably transfected AR (named as TM4/AR) and found androgens failed to transactivate AR in Sertoli TM4 and TM4/AR cells. Interestingly, additional transient transfection of AR-cDNA resulted in significant androgen responsiveness with TM4/AR cells showing ten times more androgen sensitivity than TM4 cells. In the condition where maximal androgen response was demonstrated, we then analyzed gene expression and found the expression levels of 2313 genes were changed more than twofold by transient transfection of AR-cDNA in the presence of testosterone. Among these genes, 603 androgen-/AR-regulated genes, including 164 up-regulated and 439 down-regulated, were found in both S-AR mice testis and TM4/AR cells. Ubiquitin-conjugating enzyme E2B (Ube2b) is one of the regulated genes from the digital gene expression analysis. The expression of UBE2B was decreased in the testes of the S-AR mice analyzed by quantitative RT-PCR (qRT-PCR) and immunofluorescence. The up-regulation of Ube2b gene by testosterone was further demonstrated by Western blot and qRT-PCR in TM4 cells. Moreover, luciferase assay, electrophoretic mobility shift assay, and chromatin immunoprecipitation assay validated that the ligand-bound AR activated Ube2b transcription via directly binding to the androgen-responsive element of the Ube2b promoter. In vitro analyses showed that testosterone increased UBE2B expression and activated H2A ubiquitylation, while downregulation of UBE2B blocked the testosterone-induced H2A ubiquitylation. The ubiquitylation of H2A was markedly decreased in the testes of S-AR mice by immunohistochemistry. Digital gene expression analysis showed that 113 genes were significantly down-regulated and 71 were up-regulated by UBE2B in TM4 cells. These results suggest that Ube2b, as a direct AR transcriptional target in Sertoli cells, mediates the function of AR in spermatogenesis by promoting H2A ubiquitylation. Our previous digital gene expression analysis data also showed that heat shock transcription factors 1 (HSF1) was regulated by androgen in mouse Sertoli cells. We found that the expression of Hsf1 was increased in the testes of S-AR mice compared with wild-type mice by quantitative real-time PCR and the expression of HSF1 in the S-ARSertoli cells was significantly increased as examined by immunofluorescence analysis. Besides, in vitro study showed that testosterone repressed the expression of Hsf1 in TM4 cells. Moreover, luciferase assay, electrophoretic mobility shift assay and chromatin immunoprecipitation assay showed that testosterone repressed Hsf1 expression by facilitating the binding of androgen receptor to Hsf1 promoter. Our experiment also demonstrated that testosterone downregulated the expression of heat shock protein HSP105 and HSP60 by inhibiting the transcription of Hsf1. Taken together, these results reveal that HSF1 is a novel target of androgen receptor in mouse Sertoli Cells, and testosterone and its receptor regulate the process of spermatogenesis partially by inhibiting HSF1 expression.


We present findings on the effect of microstructure on magnetic properties of the epitaxial FePt system. Epitaxial c-axis oriented FePt was synthesized on Si (100) using TiN as a template buffer. The microstructure was progressively varied from a 9nm nanoparticle system to a 30nm thick continuous thin film. We found that individual nanoparticles showed higher coercivity than the continuous thin film. Within the nanoparticle regime, coercivity increased with increasing particle size. The highest coercivity of 13500Oe was realized for a beadlike microstructure, when the individual nanoparticles just begin to merge to form a continuous thin film.

The purpose of this paper was to apply a numerical model of a 2 GHz central frequency antenna, to understand the behavior of the waves generated with a GPR, when concrete samples were under study at different antenna positions. The GPR numerical model was created based on the FDTD method and GprMax software was used to provide the 2D numerical modeling. Numerical modeling results and their further parametrical analysis were very clarifying. Arrival times, velocity increments and relative amplitudes presented a pattern according to what it was expected, when the antenna was separated from the concrete sample more than 8 cm. Nevertheless, when this distance was closer than 8 cm, due to the signals overlap the concrete reflection arrival times were altered. Despite that, the relative amplitudes for these distances did present an exponential behaviour, in agreement with what it was expected.


(1) Twenty-seven cases of rheumatic fever and rheumatic heart disease were examined for liver status.(2) In 50%, Al-P was elevated. Other liver function tests were ab-normal with lesser degree.(3) No correlation between elevated Al-P and ZTT, CCF, ESR, ASL-O titer, SGOT, SGPT, ECG findings and clinical course.(4) Elevated Al-P activity tended to develop among patients with murmur at aortic valve.(5) These abnormalities seemed to be temporary and reversible.(6) No specific histological findings enough to be called "rheumatic hepatitis" were noted in histological examinations.(7) Possible causative factors for elevated Al-P in rheumatic diseases were discussed.


Password-authenticated key exchange (PAKE) is placed in between client and a main server, which is used to share a password and authentication of password and in parallel establish a cryptographic key by exchanging messages. While doing these settings the entire password are stored in mainframe server. If the server is hacked or even malfunction happens due to internal system password stored will be open to hacker. This paper is written for consideration a two main servers operate in hand shake mode and one of them is hacked or malfunctioning. The advantage of this system even if one system is hacked, the hacker will not be able to see anyone's password or any other information. The proposed system proposes two servers, using password-authenticated key exchange(PAKE). In this case two servers will operate in handshake mode, and contribute to a generation of one key for authentication. Proposed system presents a symmetric solution for two server by using PAK, where client will get access to two different servers using cryptographic keys. The protocol develops runs in parallel operation to save time, and it is found that it is more secure and efficient than existing system.
