The issue of the inclusion or the exclusion of the "psychological subject" in the discursive conditions of the production of sense is approached through the use of the concept of "logical type", in an attempt to get a formal clarification of the sources and consequences of the above mentioned inclusion/exclusion in the field of semantics, as indicated by Eduardo Guimaraes (1995).


This article examines the War on Terror and US response strategies of discreet war through the lens of the Special Forces video game as a site of contestation between the real and the imaginary world, the nation-state and market-state, the West and the Rest. While mainstream films and news media increasingly pay homage to discreet war, the author argues that the Special Forces shooter goes a step further, by providing a participatory middle ground that seeks to naturalize and legitimize covert force solutions as acceptable instruments of statecraft. Thus, the intention of this article is to analyze the various ways in which the aesthetics and politics of the Special Forces shooter organizes, structures, and legitimates frameworks of subjecthood and sovereignty.


Heat conduction appears in almost all natural and industrial processes. In the current study, a two-dimensional heat conduction equation with different complex Dirichlet boundary conditions has been studied. An analytical solution for the temperature distribution and gradient is derived using the homotopy perturbation method (HPM). Unlike most of previous studies in the field of analytical solution with homotopy-based methods which investigate the ODEs, we focus on the partial differential equation (PDE). Employing the Taylor series, the gained series has been converted to an exact expression describing the temperature distribution in the computational domain. Problems were also solved numerically employing the finite element method (FEM). Analytical and numerical results were compared with each other and excellent agreement was obtained. The present investigation shows the effectiveness of the HPM for the solution of PDEs and represents an exact solution for a practical problem. The mathematical procedure proves that the present mathematical method is much simpler than other analytical techniques due to using a combination of homotopy analysis and classic perturbation method. The current mathematical solution can be used in further analytical and numerical surveys as well as related natural and industrial applications even with complex boundary conditions as a simple accurate technique. © 2010 Wiley Periodicals, Inc.

A survey of UK contractors' planning engineers was undertaken using an in situ framed building model to elicit comparable information. Rank ordering, correlations and exploratory factor analysis of the data confirm that cost is of primary consideration for UK contractors. However, quality is assuming an increasingly important role in the decision making process. A 'Quality Factor Group' is discussed as being the most significant underlying factor having a fundamental impact on the construction method chosen. This, based on the achievements of Japanese and American construction firms, could result in reduced costs and higher productivity in the future.

The workshop brought together mathematicians and physical scientists to discuss mathematical problems that arise from materials science. Materials science is undergoing rapid development. A number of new techniques for synthesis have recently been introduced, and it is possible today to synthesize compounds today that were impossible a decade ago. New techniques of characterization, including scanning probe microscopy, are now available and they have provided a new view on material microstructure. Finally, the availability of computational power has made it possible to study a number of previously inaccessible problems. Yet, most materials are still discovered through inspired accident and improved through expert empiricism. The essential reason for this is the complexity and the range of interactions between the electronic, atomistic, microstructural and macroscopic scales that determine the properties of materials. Mathematics can, and has, contributed to understanding this complexity.


Plant responses to abiotic stresses such as drought, salt, and heat, have been studied separately, but in fact, plants are exposed simultaneously to a combination of stresses. Therefore, the objective of this study was to explore the morphophysiological responses of the guar plant to the combination of heat, drought, and salinity with respect to that to an individual stress. Five treatments including heat, drought, salinity, a combination of multiple stresses and control were applied to two guar accessions namely "BWP-5595" and "24320". The results showed that heat stress enhanced biomass, plant height, leaf number, leaf elongation, and prolonged time to flowering. However, it reduced root length and water use efficiency, but it had moderately negative effect on leaf area, stomatal conductance and number of pods. Contrastingly, drought stress improved root length, water use efficiency, and leaf elongation. It affected negatively leaf area, plant height, and prolonged days to flowering. Drought stress moderately reduced leaf number, biomass, stomatal conductance, and number of pods. Comparatively, salinity stress had a moderately negative impact on all studied traits except leaf number, which was reduced significantly. However, the combination of multiple stresses severely affected all studied traits except water use efficiency. These results show that the adverse effects of the combination of all three stresses were more pronounced than those of either of the individual stresses. Of the two guar accessions used, BWP 5595 showed better performance than accession 24320 in most of the traits measured. This indicates that the effect of multiple stresses differs among the accessions of a species.


We consider the stabilization of an unstable discrete-time linear system that is observed over a channel corrupted by continuous multiplicative noise. Our main result shows that if the system growth is large enough, then the system cannot be stabilized. This is done by showing that the probability that the state magnitude remains bounded must go to zero with time. Our proof technique recursively bounds the conditional density of the system state to bound the progress the controller can make. This sidesteps the difficulty encountered in using the standard data-rate theorem style approach; that approach does not work because the mutual information per round between the system state and the observation is potentially unbounded. It was known that a system with multiplicative observation noise can be stabilized using a simple memoryless linear strategy if the system growth is suitably bounded. The second main result in this paper shows that while memory cannot improve the performance of a linear scheme, a simple non-linear scheme that uses one-step memory can do better than the best linear scheme.


The inter-American human rights system (IAS) faces a region that has turned distinctly hostile to human rights. For many, the ongoing crisis in Venezuela is ground zero, demonstrating the ineffectiveness of international human rights when confronted with an entrenched regime supported by major powers such as Russia and China. In this multipolar world, reinforced by a transactional and antiliberal U.S. foreign policy, human rights concerns seem to have little salience. Moreover, the regional Right-wing trend and the so-called populist resurgence underpin a political vision in the Americas that is distinctly antirights. And to make matters worse, some argue, we are anyway in the end-times of human rights—the age of international courts and liberal cosmopolitanism is over. While recognizing that these overlapping political trends pose clear challenges to the IAS, this essay offers a more cool-headed analysis to suggest that the system's future is likely to be less apocalyptic than the doomsayers predict. The first part of the essay takes a sober look at the multiple political challenges facing the IAS today and their implications for human rights advocacy. In the second part, against the background of the inhospitable conditions facing human rights activists in the region, I highlight the role of civil-society actors in strengthening and embedding the IAS. As it is precisely the regional embeddedness of the IAS on which the system's future hinges, the third part highlights the need not only to defend progress, but also to strengthen resilience.

The missional value of Belhar and the DRC-family's reunification talks The two questions are raised: a) Does Belhar in fact polarize members of the DRC-family? and b) Is Belhar in fact a stumbling block in the way of church unity? They are discussed to illuminate the contradictions embodied in these questions. It is then shown that the usage of the missional value of Belhar can point towards a direction out of the perceived dilemma in the current reunification talks in the family of DRC churches. The missional value of Belhar is explained with reference to the liberation-effect that Belhar has had on the DRC's missional relevance during the eighties and thereafter. A missional valuation of Belhar as a possible alternative to the URCSA's insistance on official acceptance of the confession by the DRC, forms the conclusion of the article.

The present paper tries to depict how Sweden and Norway were represented in the novels Gosta Berling's Saga (1891) and Children of the Age (1913) written by the two Scandinavian Nobel Prize laureates, Selma Lagerlof and Knut Hamsun, respectively. We will especially focus on the regions Varmland (in west central Sweden) and Nordland (in northern Norway). These two counties represent in fact the areas where Lagerlof and Hamsun grew up and which they knew very well. Lagerlof's story renders an area of mansion houses and ironworks from 1820, while Hamsun's novel dealing with the Segelfoss estate at a moment around 1870 depicts a society in change from old practices to modern times. Despite some supernatural elements in Gosta Berling's Saga, the two novels contribute to a geographical, social and economic identification with the regions under consideration. We thus find ourselves in front of two concentrated areas which resemble the real ones although the writing style of the authors is quite different, namely a neo-romantic way of writing with Lagerlof versus Norwegian new realism with Hamsun.


We quantize the moduli space of regular D1-D5 microstates, directly from Type IIB SUGRA. The moduli space is parametrized by a smooth closed non-selfintersecting curve in four dimensions, and we derive that the components of the curve satisfy chiral boson commutation relations, with the correct value of the effective Planck constant previously conjectured using U-duality. We use the Crnkovic-Witten-Zuckerman covariant quantization method, previously used to quantize the `bubbling AdS' geometries, combined with a certain new `consistency condition' which allows us to reduce the computation to quantizing perturbations around the plane wave.


Alternative modes of catalysis of formaldehyde hydration by a single ancillary water molecule are investigated by ab initio calculations at the STO-3G level. A cyclic transition state (FW2 double dagger) involving formaldehyde with two molecules of water is characterized and is only 0.8 kcal mol/sup -1/ higher in energy than the isolated reactants. The results indicate that gas-phase formaldehyde hydration probably proceeds via FW2 double dagger in a concerted mechanism with a Gibbs free energy of activation of 27 kcal mol/sup -1/. Addition of a water dimer to formaldehyde via FW2 double dagger is predicted to occur in water with a Gibbs free energy of activation of 16 kcal mol/sup -1/, in agreement with experiment. Empirical extrapolation to the liquid phase of entropies of activation calculated for reaction of one or two waters in the gas phase suggests that a mechanism involving three water molecules would be consistent with experiments for dioxan solution. Specific solvation by four water molecules is predicted to stabilize the zwitterionic adduct H/sub 2/O/sup +/CH/sub 2/O/sup -/ (an unbound state in the gas phase) by 111 kcal mol/sup -1/ relative to H/sub 2/O/sup +/CH/sub 2/O/sup -/ and 4H/sub 2/O or by 37 kcal mol/sup -1/ relativemore » to (H/sub 2/O)/sub 3/ and CH/sub 2/O.2H/sub 2/O. Thus a stepwise mechanism for formaldehyde hydration also may be feasible, although the energy barrier to formation of a solvated zwitterionic intermediate has not yet been calculated.« less


Despite amendments and financial investment, noncompliance with the Safe Drinking Water Act persists in portions of the United States. This study hypothesizes that rural and urban U.S. residents are exposed to different patterns of drinking water violations and contaminants. Violations (n > 9,500) for 1,133 Virginia community water systems (CWSs) from 1999 to 2016 were analyzed to (1) evaluate the effects of size and rurality on compliance, (2) identify patterns in contaminant prevalence, and (3) identify gaps in consumer protection. Results indicate that very small CWSs had significantly more monitoring and reporting (MR) violations than large systems, while medium CWSs had significantly more maximum contaminant‐level violations. Isolated rural area CWSs had significantly high MR noncompliance compared with town and urban centers. This study highlights chronic MR noncompliance across rural regions of the state, which may mask consumer health concerns. Further work directly linking health records and noncompliance is recommended to quantify this risk.


Human dander fed on by Dermatophagoides pteronyssinus (Trouessart) is deficient in vitamins. Therefore, additional B and D vitamins were tested in the laboratory on mattress dust and on house-floor dust because Aspergillus has been shown to provide extensive biosynthesis of these components. Effects of additional vitamins were minimal on mattress dust. Apparently, an adequate fungal metabolism is present, based on growth of the endemic fungi on that substrate. Yet the added vitamins greatly enhanced reproduction and growth of D. pteronyssinus in floor dust. Differential effects of additional vitamins, depending on the substrate, confirmed the importance of fungal intervention in the diet of the mite. Mattress dust seems to be the true biotope of D. pteronyssinus .


Pericarp of the fruit of Garcinia mangostana L is used for the treatment of skin infections, wounds and diarrhea in indigenous medicine of Thailand, India, Sri Lanka and Myanmar. In the present study, the inhibitory effect of extracts of pericarp ofGarcinia mangostana on bacterial growth was investigated. An inhibitory activity was exhibited by methanolic extract against Gram-positive bacteria tested (Bacillus subtilis., Staphylococcus aureus. and Streptococcus faecalis) whilst no inhibitory effect was observed against Gram -negative bacteria such as Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa. Minimum inhibitory concentration (MIC) was determined using serially diluted extract with methanol on nutrient agar. After 24 hours of incubation at room temperature, the lowest concentration of the extract which inhibited the visible bacterial growth was recorded as MIC. The MIC of the extract was 0.0005 glml against Bacillus subtilis and Staphylococcus aureus while 0.005g1ml against Streptococcus faecalis. Crude extract was fractionated with ether and ethyl acetate successively to obtain ether-soluble and ethy I acetate soluble phenolics respectively. These two fractions were found to possess inhibitory effect on growth of Bacillus subtilis., Staphylococcus aureus. and Streptococcus faecalis. Chromatographic analysis of the two fractions showed the presence of several phenolic compounds.


Background and Purpose— These studies evaluated whether gene transfer of inducible nitric oxide synthase (iNOS) is a sufficient stimulus to produce vascular dysfunction in cerebral arteries. Methods— Intracranial (pial) arteries were dissected from human brain tissue obtained during elective surgery. Isolated human arteries were incubated in vitro with adenovirus containing iNOS (AdiNOS) or a nonexpressive transgene (control, AdBglII) (500 &mgr;L, 3×109 plaque-forming units per milliliter), and vascular function was examined 24 hours later. In anesthetized rabbits, AdiNOS or AdBglII (300 &mgr;L 1×1010) was injected into the cisterna magna. Three days later, the basilar artery was removed, and reactivity was examined ex vivo. Results— In submaximally precontracted vessels, we observed impairment of NO-dependent relaxation in human cerebral arteries after gene transfer of iNOS. Maximum relaxation to bradykinin (1 &mgr;mol/L, an endothelium-dependent agonist) was 77±11% (mean±SE) after AdBglII and 31±22% (P <0.05) after AdiNOS. After AdiNOS, responses to nitroprusside (an endothelium-independent NO donor) also were impaired. Responses to both nitroprusside and bradykinin were improved by aminoguanidine (300 &mgr;mol/L), an inhibitor of iNOS. AdiNOS produced no change in vasoconstrictor responses to U46619. In basilar arteries from rabbits examined in vitro after gene transfer in vivo, responses to histamine, serotonin, and nitroprusside all were similar after AdiNOS or AdBglII. In contrast, relaxation to acetylcholine was significantly depressed after AdiNOS. Maximum relaxation to acetylcholine (10 &mgr;mol/L) was 90±3% after AdBglII and 68±5% (P <0.05) after AdiNOS. Relaxation of arteries after AdiNOS was improved by aminoguanidine. Conclusions— These studies suggest that expression of iNOS may impair NO-dependent relaxation in both human and rabbit cerebral arteries.

Objective To explore the factors associated with efficacy and adverse events of blood exchange transfusion in neonates with hyperbilirubinemia.Methods One hundred and sixty neonates with hyperbilirubinemia were treated by blood exchange transfusion in Children′s Hospital of Chongqing Medical University from Jun.2006 to Jun.2009.The adverse events were defined as one of the following conditions:Low blood oxygen saturation 85% or hypotension or apnea or bradycardia 100 times·min-1,which persisted for more than 5 minutes.The change in electrolytes,bilirubin,white blood cell,platelet,hemoglobin,the concentration of hydrogen carbonate root and pH between before and after exchange transfusion were analyzed retrospectively.The effect of the disease of neonate,internal environment parameters,the exchange transfusion volume and speeding of exchange on the incidence of adverse events were investigated.Results The incidence of adverse events were 30.63%(49/160 cases) during blood exchange transfusion.The prevalence of pulmonary hypertension in neonates with adverse events was higher than those without adverse events(8.2% vs 0,P=0.008).No significant difference was found between with and without adverse event groups in the levels of K+,Na+,Cl-,Ca2+,Mg2+and hemoglobin(Pa0.05).No difference was found concerning the speed of exchange and the exchange transfusion volume between 2 groups also(Pa0.05).Decreased level of serum bilirubin was positively correlated with the exchange transfusion volume per weight(r=0.330,P=0.000) and the level of bilirubin before therapy(r=0.829,P=0.000).Conclusions Serum bilirubin level before therapy and the exchange transfusion volume can affect the efficacy of blood exchange therapy for hyperbilirubinemia.The pulmonary hypertension is a risk factor of onset adverse events during blood exchange transfusion.


This work is researched the problem of passivity-based control for T-S fuzzy systems based on an event-triggered mechanism. The main purpose is to design a controller so that the closed-loop T-S system not only is stable and meet a prescribed mixed ffTC/passive performance, but also can effectively reduce unnecessary bandwidth utilization to some extent. By employing some novel auxiliary function-based integral inequalities, a sufficient stability and stabilization condition for the closed-loop T-S fuzzy systems is established. Following this, using a matrix decoupling method, the desired controller can be obtained. Finally, the effectiveness and applicability of our proposed approach are illustrated by a practical truck model.


Abstract In this paper, we address the importance of understanding diversity as a multidimensional lens and not as a dichotomous fact. Families are more than white or black, privileged or poor, insiders or outsiders. Further, we address the significance of understanding the feminization of poverty, as we explore the multiple ways that gender affects the reality of women's, men's, and children's lives. This discussion begins with a brief introduction; moves to discuss how to consider choosing the best texts for a course; then considers the use of humanities based materials in studying diverse families; followed by a discussion of the variety of WEB based resources available in the area; then examines the use of exercises, activities, and assignments to investigate diverse families; and concludes with a short summary. The intent of this paper is to provide an overview of how to incorporate a variety of materials and techniques in classes exploring family diversity.


: Abdominal mass is a frequent presenting symptom in the pediatric surgery OPD and many of them are diagnosed as Wilms' tumor. FNAC has been recognised as a useful tool for diagnosis of pediatric abdominal masses. But the role of FNAC in the diagnosis of Wilms' tumor is still controversial. FNAC in operable tumors was performed sometimes only when the diagnosis was in doubt on radiological evalution. It is a safe technique that does not upstage the tumor and permits positive diagnosis of nephroblastoma in almost all aspirates. Here we report a case of a two and half year old girl child admitted to hospital with right subhepatic mass. Cytodiagnosis of Wilms' tumor was given. In the present case, our aim is to stress the utility and preoperative diagnostic role of FNAC in pediatric tumor.


A sequence of random variables X(λ,n) with parameters 0 < λ≤1, n∈N is investigated. For n→∞ X(λ,n) converges in distribution to a random variable Pois(λ) obeying Poisson's law with the parameter λ. At a fixed value n all moments of the distribution of a random variable X(λ,n) of order k≤n coincide with the moments of the distribution of Pois(λ). For the value of the parameter λ=1, the random variable X(1,n) coincides with the random variable equal to the number of «fixed» points in case of random permutations of the set of elements of power n.


When to suspect periodic paralysis: report of clinical case. Periodic paralysis (PP) is an unusual disease related to a defect in muscle ion channels and caused by different pathologies. It is characterized by abrupt muscle weakness affecting rather proximal than distal muscles in lower limbs. The finding of hypokalemia during these attacks leads us to a diagnosis of hypokalemic PP and shows its initial therapeutic target.


Revolutionary concepts in propulsion are required in order to achieve high-speed cruise capability in the atmosphere and for low cost reliable systems for earth to orbit missions. One of the advanced concepts under study is the air-breathing pulse detonation engine. Additional work remains in order to establish the role and performance of a PDE in flight applications, either as a stand-alone device or as part of a combined cycle system. In this paper, we shall offer a few remarks on some of these remaining issues, i.e., combined cycle systems, nozzles and exhaust systems and thrust per unit frontal area limitations. Currently, an intensive experimental and numerical effort is underway in order to quantify the propulsion performance characteristics of this device. In this paper, we shall highlight our recent efforts to elucidate the propulsion potential of pulse detonation engines and their possible application to high-speed or hypersonic systems.


In the US continued and increased issuance of software and business method patents is criticized by many. Some argue that software and business method patents do not stimulate innovation but impede software development and encourage patent litigation. Beyond anecdotal evidence, no systematic study of the extent of patent litigation due to the new software and business method patents is available. Data is obtained from various databases and is analyzed to ascertain if there is a connection between patent litigation and these new classes of patents.


Anterior segment surgery has been a "hot topic" in ophthalmology in recent years. Since 1982, over 48 books, as well as innumerable journal articles, conferences, and articles in "throwaway" format, have been devoted to that topic. Appropriately, then, the authors raise the issue in their preface, stating that "one might question why another book on anterior segment surgery is needed." Having enlisted the contributions of 82 coauthors, the editors have organized a textbook of anterior segment surgery that concentrates on cataract surgery and puts particular emphasis on intraocular lenses, lasers, and refractive keratoplasty. The book traces the evolution of cataract surgery and includes extensive discussions of the intraocular lens and its structure, evolution, and current status. Twenty pages are devoted to anterior chamber intraocular lenses, 47 to posterior chamber intraocular lenses, and 20 to secondary intraocular lenses. Alternatives to intraocular lenses, including refractive corneal surgery, are then discussed, as are


That Q fever endocarditis can be intractable is well recognised and recurrence after valve replacement well known.1 4 Nevertheless, good results are reported with tetracycline' even in the difficult field of prosthetic endocarditis,5 though treatment may have to be continued for five years or more. Tetracycline could not be used in our patient, and the striking feature was the florid nature of the relapses occurring after an initial response to each of the antibiotics used. At operation and necropsy vegetation was luxuriant and C burnetii present in abundance despite prolonged and continuous treatment with cotrimoxazole, rifampicin, and lincomycin. Where success has been reported with these drugsl-3 they have been used in combination with or after treatment with tetracycline. We consider that there is still no acceptable substitute for tetracycline as the mainstay of treatment in Q fever endocarditis. Should circumstances arise again where tetracycline could not be used in a patient with Q fever endocarditis increased doses of rifampicin in the presence of normal liver function or even the use of chloramphenicol might be considered.

Abstract A short overview of the work on unsaturated five-membered EC–N and E–CN heterocycles, initially with EAs, later EP, and related research is given. Principal synthetic strategies to non-, carbo- and heterocyclic (C–C-bridge) anellated 1,3-azaphospholes, properties, electronic structures and reactions with organic and transition-metallic electrophiles without and with prior lithiation by tert-butyllithium are presented and illustrate the different chemistry of the aromatic 1H- and non-aromatic 3H-1,3-azaphosphole-type heterocycles. Various open questions are addressed in the outlook. Some references to the chemistry of related C-N-bridged heterocyclic anellated 1,3-azaphospholes, reviewed by Bansal, are also included. GRAPHICAL ABSTRACT


Abstract A macroscopic theory for scanning optical near field microscopy is presented. The theory, based upon the Rayleigh method, solves rigorously the electromagnetic field near a multilayer system with arbitrary one-dimension structure on its interfaces. The method is suitable for both s- and p-polarized incident light. It may also apply in cases where the resonances in the system, such as the plasmon in a metallic sample, become important.


Analysis of congestion points is an important topic for traffic management. With the rapid development of ITS, probe car data can be obtained in more and more cities. This paper introduces a method for analyzing recurrent congestion points based on historical probe car data, and proposes evaluation models for recurrent congestion points. By using this method, recurrent congestion points in Beijing are analyzed based on 57 day's probe car data collected by 7000 taxis. In the end, microscopic analysis results show that the proposed analysis method is effective.


Adaptive traffic signal control is widely recognized as an effective solution to improve urban mobility and reduce congestion in metropolises. Recently, reinforcement learning has been adopted for this transportation problem. While centralized reinforcement learning inevitably faces action space explosion, decentralized reinforcement learning allows agents to develop policies based on local observations but suffers from unstable training. In this paper, we present CommNetPF, a multi-agent decentralized reinforcement learning model incorporating communication and neighbourhood policy fingerprints for adaptive traffic signal control. With policy fingerprints in communication, agents learn to produce cooperative policies and the model converges faster. Experiments in scenarios of adaptive traffic signal control show that CommNetPF outperforms several strong baselines in terms of control performance and convergence speed.

This research concludes that the kinesthetic learning methods train fine motor children.


SERCA is a P-ATPase present in most cell types. It ultimately regulates muscle contraction and cell calcium homeostasis. SERCA disfunction is correlated to several pathologies (Brini & Carafoli, 2009). P-ATPases show significant structural similarity, presenting 10 membrane-spanning α-helices and three conserved domains (A-, P-, and N-domain) that form the catalytic site and couple ATP hydrolysis to transmembrane calcium transport. Chelerythrine, a benzophenanthridine alkaloid, although described as specific PKC inhibitor, presents reported antibacterial, antifungal, antitumour, mitochondrial and DNA damaging effects. Our recent work identified that chelerythrine potently inhibited SERCA, and our present approach is to show effects on CaATPase, ionic homeostasis, and cytotoxicity attributable to SERCA inhibition on PBMC cells. Methods: We scrutinized ATPase activity, protection against cross-linking by glutaraldehyde, SERCA trypsinolysis, cytotoxicity using MTT and FACS, and calcium concentrations with FURA2-AM. Chelerythrine inhibited rabbit SERCA ~80% at 10μM, and exhibited significant cytotoxicity at 2μM on PBMC. Cytosolic calcium rapidly increased upon addition of 0.5-1.5μM chelerythrine, possibly triggering cytotoxicity. FACS analysis corroborated this, showing a population shift to apoptotic nuclei. ATPase inhibition and cross-link assays indicate a 2:1 chelerythrine/ATPase stoichiometry, whereas the low affinity binding occurs at the nucleotide site. Proteolytic profiles suggest that chelerythrine binds to the catalytic site of SERCA and shifts it to an inactive, E2-like conformation, thereby causing Ca-induced cytotoxicity.


This paper provides an overview of an advanced simulation capability currently in use for analyzing visible and infrared sensor systems. The software system, called VISTAS (VISIBLE/INFRARED SENSOR TRADES, ANALYSES, AND SIMULATIONS) combines classical image processing techniques with detailed sensor models to produce static and time dependent simulations of a variety of sensor systems including imaging, tracking, and point target detection systems. Systems modelled to date include space-based scanning line-array sensors as well as staring 2-dimensional array sensors which can be used for either imaging or point source detection.


Anhydrous chondritic porous inter-planetary dust particles (CP IDPs) contain an assortment of highly primitive solar system components, molecular cloud matter, and presolar grains. These IDPs have largely escaped parent body processing that has affected meteorites, advocating cometary origins. Though the stardust abundance in CP IDPs is generally greater than in primitive meteorites, it can vary widely among individual CP IDPs. The average abundance of silicate stardust among isotopically primitive IDPs is approx. 375 ppm while some have extreme abundances up to approx. 1.5%. H and N isotopic anomalies are common in CP IDPs and the carrier of these anomalies has been traced to organic matter that has experienced chemical reactions in cold molecular clouds or the outer protosolar disk. Significant variations in these anomalies may reflect different degrees of nebular processing. Refractory inclusions are commonly observed in carbonaceous chondrites. These inclusions are among the first solar system condensates and display 16O-rich isotopic compositions. Refractory grains have also been observed in the comet 81P/Wild-2 samples re-turned from the Stardust Mission and in CP IDPs, but they occur with much less frequency. Here we conduct coordinated mineralogical and isotopic analyses of CP IDPs that were characterized for their bulk chemistry by to study the distribution of primitive components and the degree of nebular alteration incurred.


In this study, we proposed novel designs for computational systems that use biometrics and non-conventional imaging approaches to capture thermal motion features of humans to achieve real-time path-dependent and path-independent gait for human identification. We have developed two pyroelectric infrared (PIR) feature-generating sensor systems. One system is analog, the other digital, and both are derived from the signals generated by humans crossing the detection areas. We successfully demonstrate that by selecting suitable sensor configurations and feature extraction/training algorithms, the sensor systems are capable of performing human identification.


Carbon tetrachloride (CC14) is metabolized anaerobically to reactive intermediates by reduced liver microsomes and during the process cytochrome P-450, the enzyme responsible for CC14 metabolism, is inactivated (De Groot & Haas, 1981). Protohaem, the prosthetic group of cytochrome P-450 is also lost. We investigated the molecular mechanism of haem destruction and attempted to identify the reactive species involved. Liver microsomes from male Wistar albino rats pretreated with phenobarbitone (PB) (80 mg/kg, intraperitoneally for 3 days) were incubated anaerobically at 37°C in the presence of an oxygen-scavenging system to prevent lipid peroxidation. On addition of CC14 to either NADPHor sodium dithionite-reduced microsomal incubations a 60% loss of cytochrome P-450 was observed over a period of 5 min. Cytochrome b5 was not affected. The loss of haem, as measured by the pyridine haemochrome reaction, was parallel and equimolar to that of cytochrome P-450. To determine whether the loss of the pyridine haemochrome reaction was simply due to masking of the haem iron or to a major structural change of the haem moiety, a fluorescence technique for porphyrin estimation was also used. The same 38% loss of haem and porphyrin was found with both techniques suggesting a change in chemical constitution of the prosthetic group by a suicidal mechanism. The reactive metabolite involved is not known. CC14 undergoes two/one electron reductions to give trichloromethyl radical (-CC13) and dichlorocarbene (:CClz), evidence for which has been obtained. Both CC13 and :CC12 are reactive species and could conceivably attack the haem moiety of cytochrome P-450 leading to the destruction of the haemoprotein. The carbene binds to reduced cytochrome P-450 haem to give an unstable complex which then hydrolyses to carbon monoxide (CO) (Ahr et al., 1980). This complex is thought to be responsible for the difference spectrum obtained on addition of CC14 to reduced microsomes. When the specific carbene-trapping agent 2,3-dimethyl-2-butene (DMB) was included in the incubation almost complete abolition (> 95%) of the carbene spectrum was observed. The CC14-dependent formation of CO was also inhibited strongly by DMB. However, when the loss of haem was investigated under the same conditions, similar values were observed in the absence and the presence of DMB (39 and 37% respectively). These results indicate that: haem is the primary target of the suicidal anaerobic activation of CC14 by microsomal cytochrome P-450; loss of haem is due to a structural change, probably involving modification of the porphyrin tetrapyrrolic system; the free radical, but not the carbene, is likely to be responsible for the destruction of cytochrome P-450 haem.


Gold nanoparticles protected by the self-assembled monolayers of 9-[6-(N,N-dibutyl-amino-dithiocarbamate)-hexyl]-carbazole, CHBDTC in short, were prepared via a phase-transfer method. These surface-modified nanoparticles were characterized with UV-vis, photoluminescence spectroscopy and TEM. It was found that the CHBDTC-capped gold nanoparticles were stable under ambient conditions, which is attributed to the protection of the CHBDTC densely packed on the gold nanoparticle surface. The fluorescence emission spectra indicated that the fluorescence of CHBDTC was quenched to some extent by gold nanoparticles. And the CHBDTC-capped Au nanoparticles could be promisingly applied as biomolecular labels and in fabrication of novel photo-based nanodevices as well, owing to the photoactive sensitivity of CHBDTC.


Chapter 9 considers how particular rhetorical figures have informed and can further inform particular theoretical problems within adaptation studies: for example, how figures of similarity can redress transtheoretical hierarchies valorizing difference over similarity, how synaesthesia can refigure medium specificity theory, and how figures of contiguity can theorize adaptation's part/whole relations. It argues that figuration, as a relational rhetorical process, navigates far more complexly and variably between adaptation studies' paired terms (adapted/adapting, entities/environments, repetition/variation) than theories have done, offering alternatives to aesthetic and cultural hierarchies, radical political revolutions of them, formalist and structuralist categoricity, poststructuralist deconstruction, and postmodern pastiche and pluralism. This chapter does not constrain figures such as antimetathesis, antimetabole, metaphor, simile, metonymy, synecdoche, and synaesthesia to particular theoretical principles but probes them to generate adaptive concepts and methodologies by which to refigure adaptation studies. Whether we believe that there is a pre-existing reality that representation expresses or that representation is constructed, or a combination of the two—whether our interests lie in aesthetics, semiotics, narratology, history, culture, politics, industry, or anything else—figuration can revivify and refigure all theoretical and disciplinary purviews and create new ways of dialoguing between them. The chapter concludes with a discussion of metalepsis and the mysteries of adaptation and how the shift from analogical to digital technologies affects adaptation's preferred figure of analogy.


Endophytic fungi in leaves and twigs of Quercus petraea. Surface sterilized leaf and twig samples taken in 1989 from sessile oak (Quercus petraea) in Austria yielded host-specific as well as unspecific ubiquistic endophytes. In leaves, Aureobasidium apocryptum and Apiognomonia quercina were the most frequent taxa, while Colpoma quercinum was the dominant species in twigs. The colonization rates of individual species were subjected to seasonal variation.


After a blitz evolution of about fifty years, computer science would today seem to be a stable discipline without – some would say – any real new challenges. All solvable problems are solved, some problems turned out to be far more complicated than expected and NP is still its old obnoxious self. Computer science research consists in some people's minds of finding new permutations of existing nuggets of knowledge. The main concern of computer science teaching would seem to be instilling undergraduate students with a minimum of historical consciousness so that they do not go around eternally reinventing the wheel. This bleak – and obviously exaggerated – view on the field of computer science does however highlight one particular issue: is the future of computer science a smooth extrapolation of the past or is there some revolutionary new technology waiting around the corner to turn everything upside down? An adventurous streak – present in every human being – makes us root for the second option; and if we had to place bets there seems to be only one choice: the quantum. The past ten years have seen quantum computation evolve from science fiction into something tangible: theory is being confirmed by experiment and extremely modest trials are actually conclusive. These limitations – far from dampening our fantasy – inspire us to imagine full-fledged quantum computers – and of course the software and associated programming paradigms for these machines. Which brings us to the theme of this paper: if quantum computation is to be taken seriously, shouldn't we start thinking about bringing theoretical physics and computer science much closer together than they are today? What about the obsession with formalism of the former and the complacency of the latter? We would like to propose a gedanken experiment: confronting a theoretical physicist and a computer scientist, and exposing them to the qubit through queries from an historically conscious veteran. The following two sections an introduction to quantum computing and a close inspection of a quantum search algorithm try to accomplish two goals. First of all there is the obvious goal of introducing the state of the art in quantum computing. Additionally, we try to communicate some results of our experiment which mostly involved knowledge transfer from the physicist to the computer scientist and vice versa. In this process we identified correspondences between the two disciplines as well as concepts that are hard to grasp and explain. These insights are used in the next two sections to cut some corners and provide a tailored briefing on quantum computing for computer scientists. In the last section we express some conclusions about our experiment.


We demonstrate a novel method for obtaining optical constants of transparent material over a broad terahertz spectral range from 0.7 THz to 7.5 THz at room temperature. Based on the interferogram directly acquired by a Fourier transform infrared spectrometer (FTIR), multiple beam interference principle combining Fresnel's formula is employed to extract the refraction index and the extinction coefficient, which are the basis for calculating permittivity. It avoids the shortcomings using Kramers-Kronig (K-K) relations and overcome the frequency range of terahertz time-domain system (TDS). Moreover, this method has better stability and reserves all useful information for thin samples compared with TDS, which makes it a general processing method for terahertz dielectric measurement.


Eye movement data has become an important char-acterization in the analysis of children with autism spectrum disorder (ASD). Current eye movement measurement meth-ods require specialized expensive equipment, calibration, and trained personnel, limiting their use in general ASD screening, especially in resource-scarce environments. Therefore, collecting eye movement features based on the standard RGB camera of a mobile phone or tablet has many advantages over professional equipment. The system design is based on the Android tablet design, and the screen is divided into two parts to display the normal children and the ASD children paintings. The eye movement data of children is obtained through the front camera, so as to provide data support for future data analysis. Taking the different cooperation degrees of children into account, two collection modes are designed: 1) directly displaying the stimuli in a loop (image mode); and 2) providing the background video interspersed with the stimulus display (video mode). The demo video of the proposed system is available at: https://doi.org/10.6084/m9.figshare.21346806.v1.


The quest to have the ability to predict the location and orientation of highly fractured areas in reservoirs that produce mainly from fractures is at its climax, as oil companies develop the remaining hydrocarbon assets. Today discrete and continues fracture network models depend on mathematical equations to resolve complex fracture heterogeneities. These mathematical models are largely confined in being either stochastic or deterministic, each having its advantage and disadvantage. Geomodelers may combine these techniques to create a hybrid model to resolve complexities and overcome the disadvantages of each technique. The remaining challenge is, how good is the prediction. Normally this will take drilling a new well to know if the model is correct or not, this could be too late. This paper will introduce a novel fracture network modeling technique that takes advantage of the mathematical equations used today in modeling and guide fracture distribution based on structure kinematics and relative fracture aging. This may seem similar to the deterministic approach, but it is not. This technique focuses on building a conceptual geological model that runs through time, similar to structural restoration, and ages of fractures are noted and classified separately. The importance of having the age of the fracture system identified especially in carbonate reservoirs, is because of diagenesis. The model also takes into consideration the paleo-and-present day stress regime identifying areas of compression and extension. This novel approach was applied on a field in Kuwait before drilling a key well in a new exploration area. The model predicted that the new area has an extensional stress regime through its tectonic history increasing the chance of having open fractures. The general fracture trend of all six wells along with 3 dimensional seismic data shows a predominant NNE-SSW natural fracture trend, however the novel technique predicted that the new area has a predominate ENE-WSW. The key well was drilled in the analyzed area and fracture information obtained from borehole image logs showed an ENE-WSW orientation as predicted by the model. The fracture density over the target reservoir also matched the initial prediction. These results increased the confidence in this technique and demonstrates that fracture modeling needs to be done after structural and geological complexes are fully understood and analyzed.

Indeed, the reality of Ethiopia's agriculture and food security situation is complex because of variations across space within Ethiopia as well as variations over time due to changes in policies, weather shocks, and other factors. A complete picture of Ethiopia's agriculture and food security must include both the very serious acute and chronic food insecurity problems faced by many Ethiopians and the progress achieved in other areas and at the national level.


The construction industry is a high-risk industry in terms of job site safety. Construction workers' unsafe behaviors has been criticized as a key driving factor of construction safety incidents. A variety of studies indicate that social influence greatly affects workers' safety behaviors. However, the social influence on workers' safety behaviors in hazardous situations has not been well explored, partially due to the difficulty of simulating hazardous situations in the real world. To overcome this limitation, this research utilized a Multi-user Virtual Reality (MVR) system with motion tracking function to simulate hazardous scenarios to study how social influence affects construction workers' safety behaviors. A hazardous virtual environment with a plank between two high-rise buildings was created to simulate the high-rise walking scenarios of iron workers in construction projects. A human-subject experiment (n=126) was conducted to investigate the role of social influence in a simulated scenario involving walking across a narrow plank between two virtual high-rise buildings. The participants walked through the plank in the virtual environment while observing different scenarios, such as seeing a person slowly walking across the plank or falling from the plank. Participants' behaviors, such as the time taken to walk across the plank, were recorded and analyzed to understand effects of social influence. The results of the experiment indicate that social influence played an important role in safety behaviors in the virtual hazardous situation. In addition, the developed MVR system is able to serve similar experiment in the future.


This paper describes the application linear periodic control techniques to the analysis and design of an individual cylinder air-fuel ratio controller for an 8-cylinder engine. A model of the engine including exhaust gas mixing in the manifold is developed. The resulting system was determined to be nearly unobservable. The exhaust manifold was subsequently redesigned, and a successful controller implemented.


As a result of the research processing in the computing field, a new computing model appeared based on the development of many computing models such as parallel computing, distributed computing, and grid computing. Many normal distributed computers collaborate of achieve a function like a super computer. The computation will be assigned to this super computer rather than local computer or remote server. This is the basic concept of cloud computing. However, there is a new implementation of cloud computing was introduced based on using the internet millions of computers connected to a super cloud. Cloud computing has several advantages such as; user does not need to worry about how the cloud runs, viruses, maintenance, etc. We would expect that cloud computing is going to reshape the IT industry. In this paper we discuss cloud computing from different angles such as concept, characteristics and classifications of cloud computing.


Polyploidy belongs to the most striking factors in plant evolution. To address the role of allo- versus autopolyploid speciation in natural polyploids, we studied species of the oatlike genus Avenula, which contains diploids and polyploids with up to 22x valence. We conducted DNA sequence analyses of plasmid-cloned ITS repeats of nuclear ribosomal (nr) 35S DNA, complemented by cytogenetic studies including fluorescence in situ hybridization (FISH) with nr and satellite (sat) DNAs in 12–18x polyploid species from SE Europe and Asia Minor. Altogether, four different ITS repeat types are involved in their parentage. One is confined to Avenula armeniaca and the second shared between A. armeniaca and Avenula blaui, none of which is known from extant diploid species. The latter repeat type is characteristic of A. blaui but prevails also in one of the A. armeniaca accessions, as a result of hybridization and/or genetic introgression with an ongoing process of sequence change in favor of A. blaui repeats. The two other repeat types are encountered in Avenula adsurgens and match that of extant diploid species. Auto- and allopolyploidy are corroborated by cytogenetic data, and both types of polyploid evolution thus coexist within the genus Avenula. As exemplified by A. armeniaca, auto- and allopolyploidy are intergrading in highly polyploids, making transitional forms difficult to treat under the classical concepts of autopolyploidy, allopolyploidy, or segmental allopolyploidy. Results point to a pronounced capability of highly polyploids to incorporate further genomes via hybridization or introgression rather easily. This is considered an important evolutionary mechanism for the transfer and/or de novo origin of traits related to ecological adaptations and occupation of new or changing niches, underlining that high polyploidy is not a dead end in evolution. It might explain also the well-documented success of highly polyploids in Avenula and other grass genera relative to the diploids in terms of overall geographical distribution and abundance. Some ITS repeat types with non-Avenula identity belong to the genera Sesleria and Agropyron. All evidence, including cytogenetic data, points to an artifact caused by contamination of DNA with that of alien grass pollen, thus excluding actual hybridization between these three genera.


BACKGROUND The lack of space, as an indication for a native unilateral nephrectomy for positioning a future kidney graft in the absence of other autosomal dominant polycystic kidney disease-related symptoms, remains controversial. AIM To evaluate the surgical comorbidity and the impact on graft survival of an associated ipsilateral native nephrectomy during isolated kidney transplantation in patients with autosomal dominant polycystic kidney disease. METHODS One hundred and fifty-four kidney transplantations performed between January 2007 and January 2019 of which 77 without (kidney transplant alone (KTA) group) and 77 with associated ipsilateral nephrectomy (KTIN group), were retrospectively reviewed. Demographics and surgical variables were analyzed and their respective impact on surgical comorbidity and graft survival. RESULTS Creation of space for future graft positioning was the main reason (n = 74, 96.1%) for associated ipsilateral nephrectomy. No significant difference in surgical comorbidity (lymphocele, wound infection, incisional hernia, wound hematoma, urinary infection, need for blood transfusion, hospitalization stay, Dindo Clavien classification and readmission rate) was observed between the two study groups. The incidence of primary nonfunction and delayed graft function was comparable in both groups [0% and 2.6% (P = 0.497) and 9.1% and 16.9% (P = 0.230), respectively, in the KTA and KTIN group]. The 1- and 5-year graft survival were 94.8% and 90.3%, and 100% and 93.8%, respectively, in the KTA and KTIN group (P = 0.774). The 1- and 5-year patient survival were 96.1% and 92.9%, and 100% and 100%, respectively, in the KTA and KTIN group (P = 0.168). CONCLUSION Simultaneous ipsilateral native nephrectomy to create space for graft positioning during kidney transplantation in patients with autosomal dominant polycystic kidney disease does not negatively impact surgical comorbidity and short- and long-term graft survival.


Molecular characterization of Cryptosporidium has led to increased recognition of the diversity of species infecting animals. A Cryptosporidium Copro-Enzyme Linked Immuno Assay (Copro-ELISA) antigen detection manufactured by Savyon® Diagnostics Ltd., Ashdod, Israel, was used to screen faecal samples from cattle. Copro-ELISA Cryptosporidium antigen positive faecal samples were subjected to Nested PCR for the amplification of 830bp fragments of small subunit (SSU) rRNA gene and followed by nucleotide sequencing by targeting the 18S gene in cattle. Of the 384 bovine faeces screened, 31 (8.07%) were ELISA positive out of the 384 screened samples and 19.4% (6/31) were Cryptosporidium positive using PCR technique. Nucleotide sequencing of the bovine PCR products showed the presence of C. bovis 2 (6.5%), C. ryanae 2 (6.5%), C. andersoni 1 (3.2%) and C. ubiquitum 1(3.2%). C. ubiquitum has also been found in this study in Wurno LGA of Sokoto state, it is a new specie in the genus previously identified as Cryptosporidium Cervine genotype which was reported in wild and domestic ruminants, rodents, carnivores and primates including humans. In calves, there were no significant associations (p>0.05) in prevalence of Cryptosporidium between breeds; between sources of drinking water; between physical nature of faeces (OR=3.61:95% CI on OR: 0.36<OR<34.71); between management practices (OR=1.71: 95% CI on OR: 0.26<OR<11.41) and between sexes (OR=0.58: 95% CI on OR: 0.08<OR<3.88). Absence of the zoonotic spp (C. parvum) in the area suggests that the age group of calves studied are not likely to be source of human cryptosporidiosis.


The term 'ontoepistemosemantics' is a neologism introduced in the philosophical literature, to my knowledge, by C.U. Moulines, with which he intends to explain the close links that ontology, semantics and epistemology bear with each other. Moulines regards Frege as the first philosopher who realized the mutual imbrication among the main ontological, epistemological and semantic questions, paying special methodological attention to the latter. However, the specific proposal which Moulines gives to us, explicitly for the elucidation of science, adopts a thesis of a clear internist character, which I believe is more in line with Carnap, Goodman and Kuhn. The purpose of my work is to consider the particular proposal of ontoepistemosemantics defended by Moulines, in order to analyze its implications in relation to the treatment that the structuralist metatheory –of which Moulines himself is a major


Objectve To assess the impact of glycemic variability on blood pressure in hospitalized patients with cardiac disease. Methods In 40 patients with cardiovascular disease, the glucose levels were monitored by flash continuous glucose monitoring (FGM; Free-Style Libre™ or Free-Style Libre Pro; Abbott, Witney, UK) and self-monitoring blood glucose (SMBG) for 14 days. Blood pressure measurements were performed twice daily (morning and evening) at the same time as the glucose level measurement using SMBG. Results The detection rate of hypoglycemia using the FGM method was significantly higher than that with the 5-point SMBG method (77.5% vs. 5.0%, p<0.001). Changes in the systolic blood pressure from evening to the next morning [morning - evening (ME) difference] were significantly correlated with night glucose variability (r=0.63, P<0.001). A multiple regression analysis showed that night glucose variability using FGM was more closely correlated with the ME difference [r=0.62 (95% confidence interval, 0.019-0.051); p<0.001] than with the age, body mass index, or smoking history. Night glucose variability was also more closely associated with the ME difference in patients with unstable angina pectoris (UAP) than in those with acute myocardial infarction (AMI) or heart failure (HF) (r=0.83, p=0.058). Conclusion Night glucose variability is associated with the ME blood pressure difference, and FGM is more accurate than the 5-point SMBG approach for detecting such variability.


Falling injury is one of the most frequent accidents in construction industry. Referring to the statistic analysis of accident records from 1995 to 2000, it is found that falling injuries occurred mostly on the edge or hole of the construction, scaffold and operation platform, mechanical equipment and mold board etc. A prediction model on annual occurrence of accidents in Shanghai construction industry using the method of curve fitting is set up. The predicted values of 2002 and 2003 are compared with the realistic data to verify the model. Finally, the causation of falling is systematically analyzed considering the men-machine-environment factors, and suggestions of control measures are made.


Losartan potassium is used to treat high blood pressure (hypertension). The present study was aimed to prepare a floating drug delivery system to design a controlled release oral dosage form of Losartan potassium. This helps to overcome the demerit of limited residence time of the drug in the gastrointestinal track and hence to increase the duration of release. Hence objective of the present study is to develop Losartan potassium floating tablets by direct compression method using calcium starch as release retarding polymer. The calcium starch was synthesized by gelatinizing potato starch in the presence of sodium hydroxide and cross linking by treatment with calcium chloride. The micromeritic properties studies indicated that calcium starch is a promising pharmaceutical excipient in tablets. Floating tablets of Losartan potassium was formulated by direct compression technique, using different concentration of calcium starch and compared with HPMC K-100 as release retard polymer. As the amount of calcium starch in the tablet increased, the drug release decreased. The formulation F5 containing 125 mg calcium starch showed better controlled release of 76.38% after 12 hours.


This book draws together two important recent lines of research: labor history and family history. Speculation about these subjects goes back to the origin of sociology in the nineteenth century, when it seemed to the conservative Le Play and others that the individualistic liberalism he associated with the French Revolution was eroding the foundations of the family and, indeed, the social order. Later on, socialists echoed this argument, adding to it the thought that market oriented and especially industrial labor was inherently alienating. After 1940 the ascendance of the structurai-functional theory in American sociology (Parsons and Merton) reformulated the question in a more neutral way: here was an economic change (from a subsistence economy to a market and industrial economy) and a change in family life (from an extended and socially rather self-sufficient kin group to a nuclear family that had fewer and more specific functions). What was the general relationship between them? In the language of recent sociology, how did changes in the kinship system articulate with changes in the system of production and exchange? Professional historians did not at first take much part in this line of research. In the nineteenth century they were interested in religious or political history, particularly as these subjects came together in the rise of the nation-state and of a naturalistic and scientific world view. When professional historians did interest themselves in labor and family history, they concentrated on public policy as represented in regulation: changes in labor law and family law, for example. Whether from the sociological or the historical side, common sense suggested that economic change brought changes in family life; the underlying question was how inevitable such changes were and how desirable. The subject gained importance after 1945 because the former European colonies of the third world wanted to "modernize" and needed guidance in social and economic policy. Meanwhile, a number of social historians began to test the impressions of common sense by studying records that allowed them to make large-scale quantitative generalizations about ordinary people and


We present the results of a BeppoSAX observation of PSR J0218+4232 which, for the first time, provides detailed information on the pulsar's temporal and spectral emission properties in the broad band 1– 10 keV. We detected X-ray pulses with a pulsed fraction of 73±12 %. The pulse profile is characterized by two peaks phase separated by ∆φ = 0.47 ± 0.05. The pulsed spectrum is best described by a power–law of photon index 0.61±0.32 with an unabsorbed (2–10 keV) X-ray flux of 4.1×10 erg cm s implying a luminosity of Lx = 1.3 × 10 32 Θ (d/5.7 kpc) erg s and an X-ray efficiency of Lx/Ė = 4.8 × 10 −4 Θ (d/5.7 kpc) where Θ is the solid angle spanned by the emission beam.


According to the research, the two decades from 1950 to 1970 is characterized by one-sided approach in creating the image of local governing bodies. The latter were invariably described as a flawless always-winning and never-failing system. It was assumed that the Party authorities achieved positive results, they accepted their mistakes and took the corresponding corrective measures. Researchers of that period were deprived of the opportunity to see the life in its endless diversity. Instead they were exposed to isolated examples, official statistics and formal logics.


GHRT in GHD children is associated with a persistent decrease of FT4 concentrations and a persistent increase in FT3 levels which however remain within reference ranges. Whether these mild changes may have a clinical impact should be further investigated. At study entry, all GHD children were euthyroid and none of them became hypothyroid during the follow-up. Six months of GHRT were associated with mild reduction in FT4 and increase in FT3 levels with no differences in TSH concentrations. No further changes were observed during the following years of therapy (Figure 1). FT4 levels were negatively correlated with IGF-1 concentrations (r= -0.381, p = 0.01) (Figure 2). BACKGROUND


55 upper-division college students in two classes were administered a love-styles inventory (SAMPLE-70) at the beginning and end of the academic quarter. 25 received lectures on love and 30 did not. The former group showed a significant increase only for Storge. Endorsement patterns for both groups suggest a form of interpersonal relationship characterized by a rational and ethical quest for an ideal relationship, a willingness to make sacrifices for the beloved, a mutual regard, caring and friendship, and a sense of fate in the relationship.


Advances in distributed service-oriented computing and Internet technology have formed a strong technology push for outsourcing and information sharing. There is an increasing need for organizations to share their data across organization boundaries both within the country and with countries that may have lesser privacy and security standards. Ideally, we wish to share certain statistical data and extract the knowledge from the private databases without revealing any additional information of each individual database apart from the aggregate result that is permitted. In this article, we describe two scenarios for outsourcing data aggregation services and present a set of decentralized peer-to-peer protocols for supporting data sharing across multiple private databases while minimizing the data disclosure among individual parties. Our basic protocols include a set of novel probabilistic computation mechanisms for important primitive data aggregation operations across multiple private databases such as max, min, and top k selection. We provide an analytical study of our basic protocols in terms of precision, efficiency, and privacy characteristics. Our advanced protocols implement an efficient algorithm for performing kNN classification across multiple private databases. We provide a set of experiments to evaluate the proposed protocols in terms of their correctness, efficiency, and privacy characteristics.

Comparative performance of selected parental and different crossing pattern hybrids is an important yard stick to understand the potentiality of a breed / hybrid for evaluating the differential expression of quantitative traits. The parental breeds, foundation crosses and different cross hybrids were reared in three replications during three different seasons of the year to evaluate their performance for preand post-cocoon traits. Hybrid vigor in terms of heterosis for different crossing pattern hybrids was studied for important economic traits. The results of the study reveals that, out of different crossing pattern hybrids studied, two each of single, three-way and four-way cross hybrids exhibited better performance with desirable positive heterosis for most of the economic traits, which may be attributed to better inherent advancement and prophecy for field testing based on the overall performance and heterosis for each of the quantitative trait studied.

Neutron elastic and inelastic scattering cross sections of elemental iron were measured from 1.5 to 4.0 MeV with incident neutron resolutions of less than or equal to50 keV and at incident neutron energy intervals of less than or equal to50 keV. Cross sections for the excitation of observed levels at 0.853, 1.389, 2.097, 2.579, 2.677, 2.974, and 3.152 MeV are determined. The observed elastic and inelastic scattering angular distributions fluctuate strongly with incident energy. The experimental results are averaged over broad energy intervals and are compared with the predictions of spherical optical statistical and coupled-channel models, including consideration of direct inelastic excitations. The importance of a comprehensive data base in such energy-averaged interpretations and in the evaluation of data for technological use is stressed.


The aim of this paper is to study the notion of a quarter-symmetric metric
 connection on an almost contact B-metric manifold (M,?,?,?,g). We
 obtain the relation between the Levi-Civita connection and the
 quarter-symmetric metric connection on (M,?,?,?,g).We investigate the
 curvature tensor, Ricci tensor and scalar curvature tensor with respect to
 the quarter-symmetric metric connection. In case the manifold (M,?,?,?,g) is a Sasaki-like almost contact B-metric manifold, we get some formulas.
 Finally, we give some examples of a quarter-symmetric metric connection.


The Nova Scotia Department of Transportation and Public Works (TPW) initiated a plan for an integrated decision support system to serve four business areas: pavement management, bridge management, traffic, and safety. Driving the plan is an ongoing effort to improve and streamline business processes across the Department. It is hoped that the new systems will strengthen and reinforce the improved organization and be implemented using commercial off the shelf applications. At the foundation of the plan is a business process model describing responsibilities and procedures as they are envisioned for the future. The model identifies data collection, condition analysis, policy development, and treatment selection processes that are divided along disciplinary lines within the Department. Cross-disciplinary processes of planning, prioritization, budgeting, funding allocation, and work tracking are also identified and described. The procedures surrounding each individual process form the basis of subsystem requirements, and also help to focus the reengineering efforts. Using the results of the business and use case models a conceptual design was developed for an integrated transportation management information system. This paper describes the business process and use case models for the pavements and bridge management systems. The complete TIMS will include safety, traffic and network expansion components operating within a common framework founded upon a common database and geographic information system.


In recent years, we have been interested in the up-and-down prospects of academic societies, including both universities and academies. We have developed a University-Academy Coupling Model, which is built on the multi-agent simulation technique. In the artificial society, there exist both funding and "research seeds" that are requisite simultaneously for researchers to survive. The "seed" means a clue, source or new topic for his research activity. This paper focuses on how different efficiencies are observed in different types of organizing processes or personnel systems for research activity in universities.


Mirror neurons are responsible for imitation, empathy, and the development of language in humans. Connected directly to both the visual and auditory cortex, they translate observed (external) behavior into experienced (internal) neural firings in the premotor cortex. In other words, for the mirror neurons, there is no difference between observation and execution. The understanding of this brain region has led to novel medical applications and insight into how the human brain acquires skills. For complex motor tasks, scientific research suggests that demonstration-based instruction helps to avoid the verbal overshadowing effect and takes advantage of the mirror neurons' ability to rapidly translate the observation of complex actions into a newly learned skill. A review of recent experimental evidence on mirror neurons leads the author to recommend a shift of focus away from verbal models of instruction towards more efficient teaching methods in the performing arts that are based on observation and subconscious imitation.


S E, female, aged 81 years The first child of healthy young parents. Birth weight 6 lb 6 oz. Admitted to Sheffield Children's Hospital at 5 weeks of age, with convulsions. A diagnosis of meningoco&cal meningitis was made and she responded well to antibiotic treatment. The convulsions continued after she had recovered from the meningitis and from 14 months of age she has been on anticonvulsant drugs continually. The following drugs have been used at various times and in different combinations: phenobarbitone, phenytoin, primidone, phensuximide, amphetamine, acetazolamide, phetharbital, troxidone and pyridoxine. She has attended the hospital for several years, presenting the picture of a mentally handicapped hyperkinetic girl with incompletely controlled convulsions. Present illness: In May 1963 she complained of muscle aches and her parents noticed puffiness of her face and a change from her hyperkinetic state to one of apathy. Examination and investigations: Marked apathy. Pain and swelling of ankles, knees, fingers and wrists, resembling rheumatoid arthritis. Pale, puffy face. Low-grade, intermittent fever. Mild anmmia (Hb 13-3-10X4 g/l00 ml). ESR 40-65 mm in one hour (Wintrobe). WBC and differential count normal. Urine normal. C reactive protein raised (2+). Agglutinations in Paul-Bunnell test inconclusive. Serum electrolytes and blood urea normal. Serum y-globulin raised. Abnormal enzyme and precipitation tests of liver function. Positive LE phenomenon in blood on several occasions. A diagnosis of systemic lupus erythematosus (SLE) was made on these findings and it was thought that this might have occurred in response to the anticonvulsant drugs. For six months prior to the onset of this illness she had been receiving phenobarbitone and phensuximide, a combination which gave good ,control of her epilepsy. Treatment: The following measures have been tried but have not affected the illness: (a) Stopping phensuximide. (b) Prednisolone for six weeks in doses up to 40 mg per day. (c) Prednisolone phosphate and dexamethasone.


Irradiation of GaP with 2 MeV electrons leads to the linear growth of infrared absorption lines at 424 and 419 cm-1 with a strength ratio of 1.45+or-0.15. These lines were previously attributed to the vibrations of a displaced phosphorus atom in a site of axial symmetry but it is now shown that they can be explained by a single mode of vibration 69Ga and 71Ga respectively. Low-temperature irradiation confirm the authors' earlier data (1971) that the lines do not arise from a primary defect and imply the mobility of displaced interstitial atoms. A comparison is made with the observations of interstitial trapping by substitutional boron impurities.


We report on five hemoglobin (Hb) β chain variants that were initially identified either by electrophoretic, chromatographic or isoelectric focusing (IEF) methods. These variants do not appear to be associated with clinical or hematological abnormalities. All variants were confirmed by DNA sequence analysis.


The canons of Salisbury Cathedral mounted two major building campaigns in the thirteenth century. Documented as beginning in 1220 and ending in 1266, the first encompassed the erection of the cathedral. A reconsideration of chronicles and known documents pertinent to the campaign, some heretofore misdated, together with close examination of the masonry and reassessment of personnel responsible for the campaigns, has resulted in a verifiable chronology of the phases of construction. No document indicates the start of the second campaign, however, begun in the second half of the 1260s with the bell tower and followed by a consistory court, the cloister, and the chapter house. Earlier hypotheses based exclusively on stylistic judgments generally failed to take into account the documentable preference at Salisbury for stylistic continuity. Besides stylistic criteria, concrete evidence in the masonry, deeds, and fund-raising efforts establish a chronology for the second campaign that spans the years from ca. 1...


A fifteen level packed U cell (FLPUC) converter with eight active switch count for the grid-connected solar photovoltaic (GCSPV) application is used in this work. This converter has eight active switches with a PV source and two floating capacitors. This topology takes edge over conventional configurations in terms of components required to achieve fifteen levels in converter output voltage. The mode of operation and switching states of the fifteen level PUC converter are presented in detail. The active and reactive powers (PQ) control is incorporated for a grid-connected PV configuration, which in turn helps in an independent control over power injection into the grid. The maximum power operation is achieved for the first source connected to the PV array with the perturb and observe (P&O) MPPT technique and unity power factor is attained at the AC side. The voltages of floating capacitors are balanced at reference values using proportional-integral (PI) controllers to attain desired output voltage levels. The performance of the FLPUC based single-phase grid-tied system is analyzed under constant and variable solar environment. This topology is modeled in MATLAB®/Simulink, and test results are validated using real time emulators (OPAL-RT 5600) to meet the IEEE-519 standard for the power quality improvement.


Synopsis : To get rid of defects of ordinary vibration damping steel sheets, studies were caned out to improve weldability and thermo-endurance in the baking temperature of cosmetic coatings. It has been shown that weldability can be obtained by adding to the resin layer conductive metal particles by 5 to 40 wt % to the resin layer. The diameter (ƒÂ) of Metal particle must satisfy the following equation, with regard to the thickness of the resin layer (T) : T/ƒÂ= 1.0•`1.2. In addition, new thermosetting resins with both good vibration capability and good thermo-endurance have been developed by using the bridging reaction of curring agents between moleculas of the thermoplastic polyester resin. Based on these new findings, a new manufacturing process of coiled products of conductible vibration damping steel sheets has been established.


Hidden Markov model(HMM) as a tool for disposing signal pattern which has great ability of building time sequence, has widely been used in speech recognition. It is especially fit for signal which is nonlinear, non-stationary, bad in repeating to analysis. Based on the comparability between vibration signal and sound signal, CHMM is introduced to fault diagnosis for rotating machine. CHMM is built by using 12 rank LPC cep-strum coefficient to extract feature vectors, scaled for-wards-backwards algorithm is introduced to calculate log-likelihood avoiding the data to underflow and k-means algorithm is also used to initialize the parameter. In the given observation sequence, optimizing every model with Viterbi algorithm, with baum-welch algorithm to re-estimate parameter, and the re-estimation formula is also provided. Last, four kinds of fault experiment have been simulated on the rotor test-bed, and four kinds of fault CHMM model are built. Machine's operating state is determined by calculating the maximal log-likelihood, and the results of experiment proves that this kind of method is effective.


Concrete has the potential for greater use in future road construction with the use of modern concrete technology. Traditionally rigid pavements are characterized by high investment and low maintenance costs. The concrete has high bearing capacity, but is vulnerable to uneven settlements. It is therefore often used on roads with a high amount of heavy traffic, where the ground conditions are even, and where long sections can be laid continuously. Under these conditions the concrete today can compete with bitumen on an economic basis. The trend today towards more use of rigid pavements is also due to the need for saving costly imports of oil products. The interest in Europe for using concrete on secondary and local roads is also increasing, and concrete should perhaps be used more for tunnels, bridges, city streets and junctions with high traffic volume. Concrete on sidewalks and underpasses could also be of interest. (TRRL)
