AN ISOLATED THREE-PORT BIDIRECTIONAL DC-DC CONVERTER FOR PV BATTERY APPLICATION

In this paper anisolated three-port bidirectional DC-DC converter for Photovoltaic (PV) battery application is presented. This converter is capable of parallel power management of various renewableenergy sources. The proposed converter is designed for controlling power of photovoltaic panel, load and rechargeablebattery. The advantage of this converter is it utilizes less number of controllable switches and provides soft switching for converter primary switch. This is achieved by an inductorcapacitor-inductor resonant circuit. This converter has ability to control the battery power when there is a low and extra power according to load, and also to control maximum power point tracking for PV system. MATLAB Simulink software is used for simulation studies. Simulation results shows that irrespective of variation in solar radiation this converter is capable of maintain constant output DC link voltage by managing power between two sources. Keywords-Photovoltaic(PV), Soft switching, Multiport Converter, battery.
Toward Multi-Stakeholder Value: Virtual Human Resource Management

Some large organizations have used online virtual worlds (e.g., Second Life) in human resources (HR) in recent years, but few studies have explored how the values are generated by this technology and what factors have an impact on the performance of this technology. In this article we identify the delivery of HR functions in virtual worlds as virtual human resource management (v-HRM). In principle, v-HRM is an integrated HR strategy that enhances the management of human capital and increases the visibility of human capital to worldwide stakeholders through the establishment of an online virtual world. By introducing the features of v-HRM and summarizing the initiatives of v-HRM based on IBM experiences, we propose a model that examines the multi-stakeholder value of v-HRM. A qualitative study was employed to explore the impact of v-HRM on four types of stakeholder values through the insights from social shaping of technology approach. The case analysis results also show four types of v-HRM value facilitators. This model acknowledges how and what to implement with respect to v-HRM, and thus can be used to guide future research on v-HRM.
Silicon Uptake in Diatoms Revisited: A Model for Saturable and Nonsaturable Uptake Kinetics and the Role of Silicon Transporters1[OA]

The silicic acid uptake kinetics of diatoms were studied to provide a mechanistic explanation for previous work demonstrating both nonsaturable and Michaelis-Menten-type saturable uptake. Using 68Ge(OH)4 as a radiotracer for Si(OH)4, we showed a time-dependent transition from nonsaturable to saturable uptake kinetics in multiple diatom species. In cells grown under silicon (Si)-replete conditions, Si(OH)4 uptake was initially nonsaturable but became saturable over time. Cells prestarved for Si for 24 h exhibited immediate saturable kinetics. Data suggest nonsaturability was due to surge uptake when intracellular Si pool capacity was high, and saturability occurred when equilibrium was achieved between pool capacity and cell wall silica incorporation. In Thalassiosira pseudonana at low Si(OH)4 concentrations, uptake followed sigmoidal kinetics, indicating regulation by an allosteric mechanism. Competition of Si(OH)4 uptake with Ge(OH)4 suggested uptake at low Si(OH)4 concentrations was mediated by Si transporters. At high Si(OH)4, competition experiments and nonsaturability indicated uptake was not carrier mediated and occurred by diffusion. Zinc did not appear to be directly involved in Si(OH)4 uptake, in contrast to a previous suggestion. A model for Si(OH)4 uptake in diatoms is presented that proposes two control mechanisms: active transport by Si transporters at low Si(OH)4 and diffusional transport controlled by the capacity of intracellular pools in relation to cell wall silica incorporation at high Si(OH)4. The model integrates kinetic and equilibrium components of diatom Si(OH)4 uptake and consistently explains results in this and previous investigations.
Perfil de força isocinética dos rotadores dos ombros em jovens nadadores Shoulder rotator isokinetic strength profile in young swimmers

Abstract – Considering that some studies suggest that shoulder rotators muscle imbal-ances are related to joint pain and injury, and that there are no normative data for young swimmers, the aim of this study was: i) to describe the muscle balance, fatigue and isokinetic strength profile of the shoulder rotators in young swimmers; ii) to compare the results between swimmers and a group of young non-practitioners; iii) to contribute to the acquisition of normative data of unilateral ratios of shoulder rotators. We evaluated the shoulder rotators concentric strength and unilateral ratios (ratio between torque of external and internal rotators) of 60 swimmers (age: 14.55 ± 0.5 years old; body mass: 61.16 ± 7.08 kg) and 60 non-practitioners (age: 14.62 ± 0.49 years old; body mass: 60.22 ± 10.01 kg). The evaluation was performed in the sitting position (90° abduction and elbow flexion) at 60o.s -1 and 180o.s -1 angular speeds using an isokinetic dynamometer (Biodex System 3). The results of the fatigue ratios revealed no differences between the groups. Swimmers showed unilateral ratios of 73.39 ± 17.26% in the dominant limb (DL) and 77.89 ± 15,23% in the non-dominant limb (NDL) for assessments at 60o.s-
Matrix metalloproteinase 9 (gelatinase B) in cerebrospinal fluid of HTLV‐1 infected patients with tropical spastic paraparesis

Matrix degrading metalloproteinases (MMPs) are enzymes involved in tissue destruction associated with inflammatory diseases, including rheumatoid arthritis and neurologic disorders such as MS.’ Abnormal levels of MMPs in serum, CSF, or synovial fluids reflect uncontrolled extracellular matrix proteolysis. We describe for the first time the detection of MMP-9 (gelatinase B) in CSF from patients infected with human T-lymphotropic virus type 1 (HTLV-l), who also have chronic progressive myelopathy TSP/ HAM (tropical spastic paraparesisMTLV-1-associated myelopathy2). This disorder is characterized by spastic paraplegia associated with axonal degeneration and demyelination in spinal tract^. ^ Anti-HTLV-1-antibodies present in patients’ CSF suggest the presence of virus within the CNS, and infiltrating mononuclear cells, mainly T lymphocytes, are thought to be the main reservoir of virus. Viral expression has also been detected in rare as t r~cytes . ~ HTLV-1 may affect neural functions indirectly, via inflammatory factors such as cytokines, which are detected in infiltrating T lymphocytes and resident cells in spinal cord les i o n ~ , ~ and in CSF of TSP/HAM patients. Cytokines are potent stimulators of MMP synthesis and secretion, and we recently reported that tumor necrosis factor-a and interleukin-la secreted by HTLV-1-infected astrocytes promote MMP-9 expression.6 We therefore screened CSF from HTLV-1-positive neurologic patients (TSP/HAM) in an endemic area (eight TSPMAM patients, Martinique) in comparison with CSF from control patient with inflammatory (eight MS patients) and noninflammatory neurologic disease (NIND) (eight patients). Using zymography (figure), MMP-2 was detected in all CSF tested, but the presence of MMP-9 was inconstant and depended on the patient’s clinical status. MMP-9 was never detected in NIND patients, but was found, at high level, in all TSP/HAM CSF samples, and, in agreement with the report by Gijbels et a1. ,7 in several MS CSF samples (5/8). A larger number of CSF samples, now under study, confirms that MMP-9 is a constant finding in TSP/HAM patients. The func-
CT angiographic measurement of the carotid artery: optimizing visualization by manipulating window and level settings and contrast material attenuation.

PURPOSE To evaluate a broad range of window and level settings for various contrast material attenuation coefficients and degrees of vascular stenosis to obtain the most accurate computed tomographic (CT) angiographic measurements. MATERIALS AND METHODS A total of 25, 480 measurements were made transversely (perpendicular to the lumen) and by means of maximum intensity projection (MIP) in a phantom with stenoses of 0%-100%, contrast material with attenuation coefficients of 150-350 HU, and 14 window and 13 level settings. Edge definition was also evaluated. RESULTS There was an inherent relationship between the contrast material attenuation coefficient and the optimal window and level settings in the measurement of stenoses at both transverse and MIP CT angiography. This relationship between the contrast material attenuation coefficient D: and the optimal settings for window W: and level L: was represented by the following simple equations: W:/D: = [-2 x (L:/D:)] + 1.3, where -0.2 < L:/D: < 0.5, and W:/D: = [3.3 x (L:/D:)] - 1.3, where 0.5 < L:/D: < 1.0. With a vascular contrast material attenuation coefficient of 250-350 HU, the best transverse and MIP display settings for the window and level were 96 and 150 HU, respectively. CONCLUSION The use of optimized window and level settings at CT angiography reduces measurement variability.
Identification of four nuclear transport signal-binding proteins that interact with diverse transport signals

The transport of proteins into the nucleus requires not only the presence of a nuclear transport signal on the targeted protein but also the signal recognition proteins and the nuclear pore translocation apparatus. Complicating the search for the signal recognition proteins is the fact that the nuclear transport signals identified share little obvious homology. In this study, synthetic peptides homologous to the nuclear transport signals from the simian virus 40 large T antigen, Xenopus oocyte nucleoplasmin, adenovirus E1A, and Saccharomyces cerevisiae MAT alpha 2 proteins were coupled to a UV-photoactivable cross-linker and iodinated for use in an in vitro cross-linking reaction with cellular lysates. Four proteins, p140, p100, p70, and p55, which specifically interacted with the nuclear transport signal peptides were identified. Unique patterns of reactivity were observed with closely related pairs of nuclear transport signal peptides. Competition experiments with labeled and unlabeled peptides demonstrated that heterologous signals were able to bind the same protein and suggested that diverse signals use a common transport pathway. The subcellular distribution of the four nuclear transport signal-binding proteins suggested that nuclear transport involves both cytoplasmic and nuclear receptors. The four proteins were not bound by wheat germ agglutinin and were not associated tightly with the nuclear pore complex.
Anticholinergic actions of steroid muscle relaxants

The chronotropic effects of two new steroid muscle relaxants have been investigated. Each was compared individually with pancuronium bromide, using acetylcholine as an agonist on the isolated perfused rabbit heart. One of the drugs. Organon 6368, was very similar to pancuronium in its degree of antagonism to the bradycardia produced by acetylcholine and may therefore be a useful drug clinically. Dacuronium, on the other hand, would appear to have marked chronotropic effects at dose levels needed for adequate neuromuscular blockade and thus may be less useful.
Tissue-Preferential Expression of a Rice α-Tubulin Gene,OsTubA1, Mediated by the First Intron

The genomic clone encoding an alpha-tubulin, OsTubA1, has been isolated from rice (Oryza sativa L.). The gene consists of four exons and three introns. RNA-blot analysis showed that the gene is strongly expressed in actively dividing tissues, including root tips, young leaves, and young flowers. Analysis of chimeric fusions between OsTubA1 and beta-glucuronidase (GUS) revealed that the intron 1 was required for high-level GUS expression in actively dividing tissues, corresponding with normal expression pattern of OsTubA1. Fusion constructs lacking the intron 1 showed more GUS staining in mature tissues rather than young tissues. When the intron 1 was placed at the distal region from 5'-upstream region or at the 3'-untranslated region, no enhancement of GUS expression was observed. Sequential deletions of the OsTubA1 intron 1 brought about a gradual reduction of GUS activity in calli. These results suggest that tissue-preferential expression of the OsTubA1 gene is mediated by the intron 1 and that it may be involved in a mechanism for an efficient RNA splicing that is position dependent.
B Cell Progenitors Are Arrested in Maturation but Have Intact VDJ Recombination in the Absence of Ig-α and Ig-β1

Ig-α and Ig-β mediate surface expression and signaling of diverse B cell receptor complexes on precursor, immature, and mature B cells. Their expression begins before that of the Ig chains in early progenitor B cells. In this study, we describe the generation of Ig-α-deficient mice and their comparative analysis to mice deficient for Ig-β, the membrane-IgM, and recombination-activating gene 2 to determine the requirement of Ig-α and Ig-β in survival and differentiation of pro-B cells. We find that in the absence of Ig-α, B cell development does not progress beyond the progenitor stage, similar to what is observed in humans lacking this molecule. However, neither in Ig-α- nor in Ig-β-deficient mice are pro-B cells impaired in V(D)J recombination, in the expression of intracellular Ig μ-chains, or in surviving in the bone marrow microenvironment. Finally, Ig-α and Ig-β are not redundant in their putative function, as pro-B cells from Ig-α and Ig-β double-deficient mice are similar to those from single-deficient animals in every aspect analyzed.
ANION TRANSPORT MECHANISMS IN NEURONS *

Evidence has been presented and reviewed to show that chloride is often not in electrochemical equilibrium across neuronal cell membranes. An ATP- and sodium-dependent uptake mechanism has been described for the squid giant axon. Finally, the role of chloride in the maintenance of pH1 has been discussed. Present evidence favors a net chloride extrusion being involved in the acid extrusion process. Measurements of free, ionized chloride levels in several neuronal cells have suggested that the transmembrane distribution of chloride does not conform to thermodynamic equilibrium conditions. Net extrusion of Cl- against its electrochemical gradient has been measured in the giant neuron of the Aplysia abdominal ganglion. In the squid giant axon, cellular Cl- levels are higher than predicted from passive thermodynamic considerations. An ATP requirement as well as a dependence upon extracellular sodium has been demonstrated for chloride influx. Similarly, there is an ATP-, external Cl-dependent, Na+ influx. Thus, an ATP-requiring Na-Cl cotransport mechanism appears to account for the high cellular chloride content of the squid giant axon. Chloride efflux from several neurons appears to be involved in the regulation of intracellular pH (pHI). When pHi is made acidic, chloride efflux from the squid giant axon increases and this stimulation requires cellular ATP and external HCO3-. When pHi is measured following an acid load, it is found that pHi recovery toward normal values requires cellular Cl-, ATP and external HCO3-. Thus, an exchange process between cellular Cl- and extracellular HCO3- appears to play an important role in pH1 regulation. Such a process appears to be responsible for the lower-than-equilibrium levels of chloride found in certain neuronal cells.
Post-mortem proteolysis and tenderisation are more rapid and extensive in female duck breast muscle

Abstract The post-mortem proteolysis and tenderisation between male and female duck breast muscles were compared. The results showed that μ-calpain activity, desmin content and shear force decreased more quickly in female than in male samples stored at 5°C. It is suggested that the post-mortem proteolysis and tenderisation are more rapid and extensive in female duck breast muscle.
Review on Dental Implantology

Aim of the work: in this review, we tried to show all details about dental implant, its components, types in the market, usage, case selection and diagnosis, indications and contraindications. Patients and method: Pubmed, Google Scholar have been used to search for papers that addressed dental implantology, preoperative diagnosis of the cases and both of their medical and dental history were considered during searching. Results: it was obvious that dental implant has been the first choice by patients for replacing their missed teeth because of their numerous advantages specially in preserving the adjacent teeth and esthetics, but it may be more expensive than fixed bridges or removable prosthodontics. Conclusion: dental implant is a root-like structure made of titanium. It is composed of three main parts (fixture, abutment, crown). Case selection is the main point for implant success, so, before implant surgical procedure, the dentist asks the patient for full mouth x-ray, medical history and dental history.
Modular L-values of cubic level

Using a simple relative trace formula, we compute averages of twisted modular L-values for newforms of cubic level. In the case of Maass forms, we obtain an exact formula. For holomorphic forms of weight k > 2, we obtain an asymptotic formula which agrees with the estimate predicted by the Lindelof hypothesis in the weight and level aspects.
Modulation of Acid Phosphatase and Lactic Dehydrogenase in Hexachlorocyclohexane‐Induced Hepatocarcinogenesis in Mice

The present study was designed to elucidate the involvement of acid phosphatase (ACP) in metastasis and lactate dehydrogenase (LDH) as an immediate compensatory alleviation mechanism for energy stress in liver lesions induced by hexachlorocyclohexane in Swiss mice. Animals were continuously exposed to hexachlorocyclohexane (500 ppm) for 2, 4, and 6 months. Neoplastic nodules and tumors developed after continuous exposure for 4 and 6 months, respectively. The distribution pattern of both enzymes markedly varied in neoplastic nodules and tumors. Intense ACP activity was more observed only in sinusoids and blood vessels of neoplastic nodule, whereas an overall increase in ACP activity was observed in the tumor. Noticeably, a significant decline in LDH activity was noted after 2 and 4 months of exposure, whereas LDH in a tumor region showed intense enzymatic activity. The role of acid phosphate in metastasis and LDH in oxidative stress during hepatocarcinogenesis induced by hexachlorocyclohexane has been discussed. © 2012 Wiley Periodicals, Inc.

fpgaConvNet: Automated Mapping of Convolutional Neural Networks on FPGAs (Abstract Only)

In recent years, Convolutional Neural Networks (ConvNets) have become the state-of-the-art in several Artificial Intelligence tasks. Across the range of applications, the performance needs vary significantly, from high-throughput image recognition to the very low-latency requirements of autonomous cars. In this context, FPGAs can provide a potential platform that can be optimally configured based on the different performance needs. However, the complexity of ConvNet models keeps increasing leading to a large design space. This work presents fpgaConvNet, an end-to-end framework for mapping ConvNets on FPGAs. The proposed framework employs an automated design methodology based on the Synchronous Dataflow (SDF) paradigm and defines a set of transformations on the SDF graph in order to efficiently explore the architectural design space. By treating high-throughput and latency-critical systems separately, the presented tool is able to efficiently explore the architectural design space and to generate hardware designs from high-level ConvNet specifications, explicitly optimised for the performance metric of interest. Overall our framework yields designs that improve the performance density and the performance efficiency by up to 6× and 4.49× respectively over existing highly-optimised FPGA, DSP and embedded GPU work.
Towards a Good Mix in Blended Learning for Small and Medium-Sized Enterprises - Outline of a Delphi Study

The mix that is suitable to target the specific learning needs and is likely to be accepted by SMEs has yet to be clarified. Recommendations for a good mix of blended learning in SMEs will be developed using a Delphi study design, implemented as a so-called e-Delphi. The sample will be SMEs from Germany and Ireland, international providers of e-learning, blended learning and lifelong learning as well as researchers in these fields. Recent experience with contacting selected participants for the Delphi study did show big differences for Germany and Ireland. First conclusions can be expected after the first round of the Delphi study has been analyzed in October 2006.
Does Management Matter in Schools?

We collect data on operations, targets and human resources management practices in over 1,800 schools educating 15-year-olds in eight countries. Overall, we show that higher management quality is strongly associated with better educational outcomes. The UK, Sweden, Canada and the US obtain the highest management scores closely followed by Germany, with a gap to Italy, Brazil and then finally India. We also show that autonomous government schools (i.e. government funded but with substantial independence like UK academies and US charters) have significantly higher management scores than regular government schools and private schools. Almost half of the difference between the management scores of autonomous government schools and regular government schools is accounted for by differences in leadership of the principal and better governance.
Prevalence of antibodies to the hepatitis E virus in pigs from countries where hepatitis E is common or is rare in the human population

Hepatitis E virus (HEV) is a very important public health concern in many developing countries where epidemics of hepatitis E are common. Sporadic cases of clinical hepatitis E not only occur in these countries but also occur uncommonly in patients with no known epidemiological exposure to HEV in industrialized countries. The source of infection in industrialized countries is unknown but it has been suggested that animals might serve as a reservoir for HEV in both settings. We recently identified and characterized an HEV strain (swine HEV) that infects large numbers of pigs in the United States. To assess the potential of pigs to serve as a global reservoir of HEV, we measured the prevalence of HEV antibodies in pigs in two countries where hepatitis E is endemic and two countries where it is not. Swine herds in all four countries contained many pigs that were seropositive for IgG anti‐HEV, although the percentage of seropositive pigs varied greatly from herd to herd. A very limited number of pig handlers in the two endemic countries were also tested and most of them were found to be seropositive for HEV. The results from this study suggest that hepatitis E is enzootic in pigs regardless of whether HEV is endemic in the respective human population. J. Med. Virol. 59:297–302, 1999.
