Design of a Low Voltage DC Microgrid Based on Renewable Energy to be Applied in Communities where Grid Connection is not Available

This article compares different topologies for Low Voltage DC networks that might be used in the electrification process of communities without access to electricity. These type of networks usually include distributed generation (mainly PV), energy storage (batteries) and loads in several houses. Currently, these grids are being built isolated from the AC network and without including any power converter to control the power flow. A comparison between the typical converterless approach and three alternative topologies is developed, one including a DC/DC converter connected to the central battery, another including converters connected to the PV generation systems, and a third one including converters connected to each generation and storage system.
Invited Tutorial: FPGA Hardware Security for Datacenters and Beyond

Since FPGAs are now available in datacenters to accelerate applications, providing FPGA hardware security is a high priority. FPGA security is becoming more serious with the transition to FPGA-as-a-Service where users can upload their own bitstreams. Full control over FPGA hardware through the bitstream enables attacks to weaken an FPGA-based system. These include physically damaging the FPGA equipment and leaking of sensitive information such as the secret keys of crypto algorithms. While there is no known attacks in the commercial settings so far, it is not so much a question of if but more of when? The tutorial will show concrete attacks applicable on datacenter FPGAs. The goal of this tutorial is to prepare the FPGA community to impending security issues in order to pave way for a proactive security. First, we will give a tour through the FPGA hardware security jungle surveying practical attacks and potential threats. We will reinforce this with live demos of denial of service attacks. Less than 10% of the logic resources on an FPGA can draw enough dynamic power to crash a datacenter FPGA card. In the second part of the tutorial, we will show different mitigations that are either vendor supported or proposed by the academic community. In summary, the tutorial will communicate that while FPGA hardware security is complicated to bring about, there are acceptable solutions for known FPGA security problems.
Potential of Anionic Surfactant Modified Alumina in Removal of Crystal Violet from Aqueous Solution

4.1. 1 Crystal Violet Crystal violet or Gentian violet is triarylmethane dye. The dye is used as a histological stain and in Gram’s Method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic properties and was formerly important as a topical antiseptic. The medical use of the dye has been largely superseded by more modern drugs, although it is still listed by the World Health Organization [1] .
The Effect of Entrepreneurship on Start-Up Open Innovation: Innovative Behavior of University Students

This study investigates whether higher start-up intention leads to innovative behavior and whether innovative behavior is increased by the medium of entrepreneurship. This study tested the hypotheses by conducting a survey on students participating in entrepreneurship club activities in university. The results showed that start-up intention affects innovative behavior and has a significant effect on the sub-factors of entrepreneurship, such as innovation, risk taking, and proactiveness. The result of an analysis of the mediating effect of entrepreneurship on innovative behavior showed that all sub-factors performed a partially mediating role. It can therefore be said that higher start-up intention leads to more innovative behavior and that entrepreneurship serves as an important link in this relationship. These results show that increasing start-up intention may lead to innovative behavior and imply that this has educational relevance in cultivating entrepreneurship. However, this study is limited in terms of the generalizability of the results, as the subjects are university students participating in entrepreneurship club activities in Korea. Therefore, more significant outcomes can be obtained in further research by targeting a broader scope of subjects.
M ay 2 01 5 Universal structure of two and three dimensional self-gravitating systems in the quasi-equilibrium state

We study a universal structure of two and three dimensional self-gravitating systems in the quasiequilibrium state. It is shown numerically that the two dimensional self-gravitating system in the quasi-equilibrium state has the same kind of density profile as the three dimensional one. We develop a phenomenological model to describe this universal structure by using a special Langevin equation with a distinctive random noise to self-gravitating systems. We find that the density profile derived theoretically is consistent well with results of observations and simulations.
FindHer: a Filter to Find Women Experts

Women are underrepresented in many spheres of our societies, including research. A common excuse for exclusively male line-ups is that suitable women could not be found. One way of promoting visibility of women in industry and academia is to explicitly provide solutions to ﬁnd them. Expert Connect is a publicly searchable database of Australia’s researchers that now includes FindHer, a ﬁlter to ﬁnd women experts in any ﬁeld of research. In this industry paper, we evaluate Natural Language Processing and Computer Vision technologies for gender determination within the aim of automating gender proﬁle tagging for FindHer. We found current off-the-shelf tools are highly effective in detecting gender from names and photos. Nevertheless, a human-in-the-loop approach should be preferred to a fully automatic one, since ethical concerns might arise.
periodic proof factor in a nonlinear distributed consensus

A purely distributed consensus in an efficient digital currency would enable a nearly instant and nearly free transaction system across the globe; independent of border, nation, government or bank. We herein propose a time-accepted nonlinear consensus that maintains the efficiencies of Proof-of-Stake, while increasing the distribution and security of the consensus systemwith a diminishing probability to find a proof and receive reward over time. This is achieved via a periodic time-acceptance function that is proportional to the coins held and relative to network strength. This time-acceptance model ensures that relatively active staking maximizes reward and probability to form consensus via proof. This incentivizes direct and active protection of the network. Furthermore, voluntary participation in the network is driven by an inflation targeted interest rate that is inversely proportional to network strength. This increasingly rewards nodes which consistently reinforce network security. This is in addition to a time-diminishing inflation rate that is proportional to network strength and active participation in reaching consensus, and relative to the Proof-of-Work distributed initial supply. A combination of costs and rewards favors direct participation in the protection of the consensus, providing enhanced security, equability, and distribution of both consensus and currency over time.
Preparation and Performance Analysis of High-Viscosity and Elastic Recovery Modified Asphalt Binder

This study presented the preparation and performance of a kind of high viscosity and elastic recovery asphalt (HVERA) by using some modifiers. The performance of styrene-butadiene-styrene (SBS), rock asphalt (RA), crumb rubber (CR), and stabilizing agent (SA) for different modifiers was investigated by conventional binder test. Effects of modifiers on the high- and low-temperature properties of HVERA were investigated. The dynamic viscosity (DV) test, dynamic shear rheometer (DSR), and bending beam rheometer (BBR) analysis indicated that the high- and low-temperature rheological properties of asphalt were improved attribute to the addition of mixture of modifiers. Meanwhile, the short-term aging and long-term aging were simulated by rolling thin film oven (RTFO) and pressure aging vessel (PAV) tests. Furthermore, the Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) measurements were conducted for obtaining the mechanism and microstructure distribution of the modified asphalt binders. From the test results in this study, it was evident that the addition of SBS, RA, CR, and SA into a neat asphalt binder could both significantly improve the viscosity of the binder at high temperature and lower the creep stiffness at low temperature, which was beneficial to better both high-temperature stability and low-temperature cracking resistance of asphalt pavements. It was proved that the high temperature grade of HVERA could be increased by increasing of RA and a proper percentage of modifiers could be improved by the low temperature grade of HVERA.
Vertical Integration and Supply Chains

Vertical integration is central to understanding patterns of economic activity, but there has been limited empirical work measuring the extent to which firms own and utilize direct upstream and downstream production links for sourcing physical inputs. We use administrative data from Karnataka, India on the movement of goods, both within and outside the firm, and find that 13% of input value can be sourced from vertically integrated upstream establishments. Of this potential 13%, somewhere between 30 40% of trade actually materializes. This suggests that the supply of physical goods along the production chain is an important rationale for vertical integration. Notably, within the set of vertically integrated firms, firms which source at least one product from within account for over three-quarters of economic activity. We look at factors associated with the decision to source a given product from within, and find that firm size, distance to outside and within firm suppliers, frequency of input requirement, product relationship specificity, volume, R&D requirements and competition both upstream and downstream are important factors. Finally, we look at factors associated with the ownership of an vertically integrated establishment and find that firm size, product specificity, R&D requirements and competition matter.
Nanocatalysts Containing Direct Electron Transfer-Capable Oxidoreductases: Recent Advances and Applications

Direct electron transfer (DET)-capable oxidoreductases are enzymes that have the ability to transfer/receive electrons directly to/from solid surfaces or nanomaterials, bypassing the need for an additional electron mediator. More than 100 enzymes are known to be capable of working in DET conditions; however, to this day, DET-capable enzymes have been mainly used in designing biofuel cells and biosensors. The rapid advance in (semi) conductive nanomaterial development provided new possibilities to create enzyme-nanoparticle catalysts utilizing properties of DET-capable enzymes and demonstrating catalytic processes never observed before. Briefly, such nanocatalysts combine several cathodic and anodic catalysis performing oxidoreductases into a single nanoparticle surface. Hereby, to the best of our knowledge, we present the first review concerning such nanocatalytic systems involving DET-capable oxidoreductases. We outlook the contemporary applications of DET-capable enzymes, present a principle of operation of nanocatalysts based on DET-capable oxidoreductases, provide a review of state-of-the-art (nano) catalytic systems that have been demonstrated using DET-capable oxidoreductases, and highlight common strategies and challenges that are usually associated with those type catalytic systems. Finally, we end this paper with the concluding discussion, where we present future perspectives and possible research directions.
ブロイラーの飼料給与制限•再給与プログラムは成長,飼料要求率および脂肪蓄積を改善させるか

飼料給与制限•再給与がブロイラー雌雛における成長,肝臓の脂肪酸合成,肝臓と血清中の各脂質画分,腹腔内脂肪重量および屠体成分に及ぼす影響を検討した. 5日齢のブロイラー雌雛180羽を4区に分け,1区は自由採食とし,他の3区は,1区の採食量の50%をそれぞれの区に5,10あるいは15日間給与した. その後,各区とも56日齢の実験終了まで飼料は自由採食とした. 自由採食区の50%に10あるいは15日間飼料給与量を制限した区では,56日齢における体重は自由採食区よりも明らかに小さかったが,飼料要求率は改善された. 給与制限をした雛の腹腔内脂肪重量は27日齢では増加する傾向であったが,56日齢では減少した. 肝臓のacetyl-CoA carboxylase活性は飼料給与制限終了時には低下し,自由採食として2日間と27日齢では明らかに増加したが,56日齢では低下した. 15日間給与制限した雛のfatty acid synthetase活性は飼料給与制限終了時には低下したが,自由採食として2日目で増加し,その後27および56日齢では低下した. 27日齢において,肝臓中トリグリセリドは5日間制限給与した雛で,血清中トリグリセリドは5日間あるいは15日間制限給与した雛でそれぞれ増加した. 56日齢では肝臓中トリグリセリドは10あるいは15日間給与制限した雛で減少し,血清中トリグリセリドは給与制限したすべての雛で減少した. 飼料給与制限した雛の血清中全コレステロールは27および56日齢で減少した. 15日間の給与制限は27日齢および56日齢での屠体中の蛋白含量を増加させた. 以上の結果は,ブロイラー雌雛を飼料給与制限•再給与することによって飼料要求率が改善され,腹腔内脂肪重量,肝臓での脂肪酸合成および血清中コレステロール濃度が低下した. しかし屠体中脂肪含量には影響が見られず,また10,15日間制限給与によって屠体中灰分含量が低下し,本実験における飼料給与制限•再給与プログラムはブロイラーの成長および屠体成分を改善しなかった.
Geriatric Patient Admissions to the Emergency Service

Objective: In this study, we aimed to analyze the demographic features of patients older than 65 years admitted to the emergency department. Material and Methods: All patients who were over 65 years old and admitted to a tertiary care emergency department were included in this retrospective study. Information, including admission dates (month, season), age, sex, admission type, diagnosis, duration of hospitalization, and outcome in the emergency department of the patients, was evaluated. The obtained data were analyzed with student t-test and chi-square test by using SPSS 17.0 software. Results: Of 238,222 patients admitted to the emergency department, 8793 (3.6%) were over 65 years old; 58% of the patients were female and 42% were male. The rate of chronic obstructive pulmonary disease (COPD) among respiratory problems in males and the rate of hypertension among cardiac problems in females were found to be significantly high. The highest admission rate was in the autumn months (32.6%). The most common reason for admission to the emergency department was cardiac problems (21.7%). This was followed by neurological problems, trauma, respiratory system problems, and urinary tract infections, respectively. The highest mortality rate was 45% in the general intensive care unit. The most frequent cause for mortality was cardiac problems. Conclusion: Cardiac problems were the most common cause of admissions to the emergency department, hospitalization, and mortality in geriatric patients. Future studies for determining the admission rate and most frequently observed illnesses of geriatric patients might be helpful in developing special care areas and special scanning tests for geriatric patients.

A Short-Term Study of Chimeric Monoclonal Antibody cA2 to Tumor Necrosis Factor α for Crohn's Disease

Background Studies in animals and an open-label trial have suggested a role for antibodies to tumor necrosis factor α, specifically chimeric monoclonal antibody cA2, in the treatment of Crohn's disease. Methods We conducted a 12-week multicenter, double-blind, placebo-controlled trial of cA2 in 108 patients with moderate-to-severe Crohn's disease that was resistant to treatment. All had scores on the Crohn's Disease Activity Index between 220 and 400 (scores can range from 0 to about 600, with higher scores indicating more severe illness). Patients were randomly assigned to receive a single two-hour intravenous infusion of either placebo or cA2 in a dose of 5 mg per kilogram of body weight, 10 mg per kilogram, or 20 mg per kilogram. Clinical response, the primary end point, was defined as a reduction of 70 or more points in the score on the Crohn's Disease Activity Index at four weeks that was not accompanied by a change in any concomitant medications. Results At four weeks, 81 percent of the patients giv.
The optic flow field: the foundation of vision.

As a basis for understanding the visual system, we need to consider the functions that vision has to perform, which are pre-eminently in the service of activity, and the circumstances in which it normally operates, namely when the head is moving. The fundamental ecological stimulus for vision is not a camera-like time-frozen image but a constantly changing optic array or flow field, the description of which must be in spatio-temporal terms. A mathematical analysis of the optic flow field is presented, revealing the information that it affords for controlling activity - information both about the topography of the environment and about the movement of the organism relative to the environment. Results of human behavioural experiments are also reported. It is suggested that the optic flow field should be the starting point in attempting to discover the physiological workings of the visual system.
Blogging in Occupational Therapy: Knowledge Sharing, Professional Development, and Ethical Dilemmas

While serving as a journal, a blog is, generally, a form of social media that can be accessed by anyone, online (Miller and Pole 2010). Blogs authored by healthcare professionals are increasingly prevalent (Lagu et al 2008). This opinion piece draws on the author's experience in exploring how blogging can develop reflective skills and the interactive forum that a blog can enable. It also raises the inherent risks of blogging, and suggests that, in order for occupational therapists to make use of this opportunity for continuing professional development, specific guidance about the use of social media needs to be created.
Effect of different sources of protein on performance, body composition and intestinal morphology of piglets

A study was carried out to evaluate the effect of dried skim milk (LDP) in weaning diets containing different levels of high-protein soybean meal (PCS), for piglets weaned at 21 days of age. Five diets were compared, from weaning to 14 days post-weaning: T1 - basal diet, soybean meal (FS) as the main protein source; T2 and T4 - replacement of 30 and 50%, respectively, FS from basal diet by PCS; T3 and T5 - replacement of 30 and 50%, of FS from basal diet by PCS and 20% by LDP, respectively. The partial replacement of FS by PCS or LDP did not affect the performance neither the body composition or deposition tissues ratios of piglets in anyone of the evaluated period. The mucous membrane height and villus height at 14 days post-weaning were not affected by the protein source of the diet, but crypt depth was reduced by PCS, regardless of diet supplementation with LDP. The protein source did not affect performance neither body composition of piglets, but PCS provided a reduction of morphologic changes of the intestinal mucous membrane, signed by the reduction of the crypt depth.
Propofol attenuated the effect of TNF-α on occludin expression by inhibiting HIF-1α/VEGF/VEGFR-2/ERK signaling pathway in hCMEC/D3 cells

Background: The levels of tight junction proteins (TJs), especially occludin, correlate with blood-brain barrier (BBB) disruption caused by inflammation in central nervous system (CNS). It has been reported that propofol, the most commonly used anesthetic, could inhibit inflammation response in CNS. In this study, we investigated the effects of tumor necrosis factor-α(TNF-α) and propofol on occludin expression in human cerebral microvascular endothelial cell line, D3 clone (hCMEC/D3 cells), and explored the underlying mechanisms. Methods: The hCMEC/D3 cells were treated with propofol, followed by TNF-α. The expression and phosphorylation of Hif-1α, VEGF, VEGFR-2, ERK, p38MAPK and occludin were measured by Western blot analysis. The cell viability of hCMEC/D3 cells was measured by cell counting kit-8. Results: TNF-α (10 ng/ml, 4 h) significantly decreased the expression of occludin, which was attenuated by propofol (25 μM). TNF-α induced Hif-1α/VEGF/VEGFR-2/ERK signaling pathway, while propofol could inhibit it. TNF-α induced the phosphorylation of p38MAPK, while propofol had no effect on it. In addition, the inhibitors of Hif-1α, VEGFR-2, and ERK could reduce the effect of TNF-α on occludin expression. Conclusion: TNF-α could decrease the expression of occludin via activating Hif-1α/VEGF/VEGFR-2/ERK signaling pathway, which was attenuated by propofol.
Crosses of NOD Mice With the Related NON Strain: A Polygenic Model for IDDM

Chromosome locations of non–major histocompatibility complex (MHC) genes contributing to insulin-dependent diabetes mellitus (IDDM) in mice have been determined by outcrossing NOD mice to other inbred strains congenic for the NOD MHC haplotype (H2g7). At least nine non-MHC IDDM susceptibility genes (Idd) were previously identified at first backcross (BC1) after outcross of NOD to C57BL/10.H2g7 congenic mice (B10.H2g7). We investigated whether the same set of Idd loci segregated with IDDM susceptibility after outcross of NOD to NON.H2g7 congenic mice. Since the outcrosses to NON.H2g7 and B10.H2g7 were performed in the same vivarium, direct comparisons were made of the chromosomal locations and relative strengths of Idd alleles in diabetic progeny from the two different outcrosses. In comparison with the NOD × B10.H2g7 outcross, the NOD × NON.H2g7 outcross produced significantly higher IDDM frequencies in F1, F2, and BC1 generations. The high F2 diabetes frequency allowed evaluation of the effects of homozygous expression of both the susceptibility and the resistance allele at Idd loci. This analysis demonstrated that no single non-MHC Idd locus was essential for the onset of diabetes in this cross. After outcross to NON.H2g7, Idd4 (chromosome [Chr] 11), Idd5 (Chr 1), and Idd8 (Chr 14) did not segregate with IddM in either the BC1 or the F2 generation. Diabetogenic NOD-derived alleles at Idd2 (Chr 9), Idd3 (Chr 3), and Idd10 (Chr 3) were segregating in the BC1. An NON-derived allele contributing to susceptibility on Chr 7 (Idd7) was also detected. Dominant traits, detectable only in the F2 cross, were encoded by Chr 4 (Idd9) and two newly mapped loci on Chr 13 (Idd14) and 5 (Idd15). A third dominant trait was encoded by Chr 6 (possibly Idd6), but here, in contrast to Idd9, Idd14, and Idd15, the NON allele was diabetogenic. Stepwise logistic regression analysis of the BC1 and F2 data confirmed that the ability to identify certainty of the non-MHC Idd loci was contingent on the extent of homozygosity for NOD background genes. This study shows that the diabetogenic phenotype can be achieved through the actions of variable combinations of MHC-unlinked genes and a diabetogenic MHC haplotype.
