Simulating the dynamic electrothermal behavior of power electronic circuits and systems

The simulator solves for the temperature distribution within the semiconductor devices, packages, and heat sinks (thermal network) as well as the currents and voltages within the electrical network. The thermal network is coupled to the electrical network through the electrothermal models for the semiconductor devices. The electrothermal semiconductor device models calculate the electrical characteristics based on the instantaneous value of the device silicon chip surface temperature and calculate the instantaneous power dissipated as heat within the device. The thermal network describes the flow of heat from the chip surface through the package and heat sink and thus determines the evolution of the chip surface temperature used by the semiconductor device models. The thermal component models for the device silicon chip, packages, and heat sinks are developed by discretizing the nonlinear heat diffusion equation and are represented in component form so that the thermal component models for various packages and heat sinks can be readily connected to one another to form the thermal network. >
BUREAUCRATIC SUPPORT-RELATED FACTORS AND THEIR RELATIONSHIPS TO THE IMPLEMENTATION OF A DECENTRALISED FISHERIES EXTENSION IN JAVA, INDONESIA

This study is aimed to assess the relationships between bureaucratic support-related factors and the implementation of decentralisation policy in fisheries extension. Population of this study comprised fisheries extension officers (FEOs) at the Rural Extension Centres (RECs) in Java, Indonesia. A multistage random sampling method was used for selecting the subjects of the study. A total of 50 FEOs at 10 districts in three provinces were covered. Data were collected from January to March 1998 by using interview and self-administered techniques. Descriptive statistics and correlation analyses were applied. Decentralisation policy in fisheries extension was not effectively implemented at the local level. Effectiveness in programme planning, decision-making, resources utilisation, and provision of benefits were not implemented as expected by the policy objectives. As beneficiaries of services, fishers received little from the implementation of decentralised fisheries extension. The effectiveness of the policy implementation was positively and significantly correlated to the bureaucratic support-related factors, which comprised of support from district government bureaucracy and supervision as well as guidance from related agencies.
Analysis of threshold voltage fluctuations due to short channel and random doping effects

A two-dimensional (2-D) simulation study of short channel and random dopant effects on threshold voltage lowering and fluctuations in 90 nm MOSFET's is presented. The systematic analysis of short channel and random dopant effects was carried out in 2-D on a scale to provide quantitative predictions. Simulations based on a single multigrid solution of the Poisson equation followed by the solution of a simplified current continuity equation are used in the simulations. Both short channel and random dopant effects, on threshold voltage fluctuations are simulated and discussed in MOSFET's. The simulation results will be the start point for the analysis of threshold voltage fluctuations through the comparison with analytical models based on dopant number fluctuations. The simulations show that the threshold voltage fluctuations are principally determined by the fluctuation in the dopant number.
THE POTENTIAL SEED PRODUCTIVITY OF ORCHID FLOWERS AND

1 ABSTRACT: The relationships between potential seed productivity, pollinia structure, methods of pollen reception, the sizes of. the stigma, and the visitation frequency of orchid flowers were studied. The method of pollen reception by the stigma has a more dominant influence on the ovule number than the structure of the pollinia. Although Cephalanthera species investigated have the most primitive pollinia structure among spacies studied, their number of ovules is higher than in Orchis soriophora, Listera ovata, Dactylorhiza romana, Orchis tridentata, Orchis simia, Platanthera bifolia, P. chlorantha, and Steveniella satyrioides. A larger part of soft pollinia of Cephalanthera is scraped by the rostellum of one flower from pollinators ("scraping" method). With the "contact" method of pollen reception (Listera and Orchidinae species) only the apical part of the pollinia comes in contact with stigmatic secretion, and a small amount of pollen of the pollinia is delivered onto the stigma. Therefore, the spacies with a scraping method have lower pollen/ ovule (P/O) ratios than those with a contact method. In each method of pollen reception the ovule number and P/O ratio depend on the consistency of pollinia. The ovule number is lower in species with soft pollinia than in those with sectile or hard ones. The P/O ratio, on the contrary, is higher. Ovule number is also correlated with the deposited pollen loads. Within one species the ovule number has shown a high degree of correlation with the stigmatic area. However, at the genus level and above such a correlation was not observed bacause of the differences in pollinia reception methods, the consistency of pollinia, and pollen density on the pollinators. Aggregation of pollen into pollinia seems to be an adaptation to the increasing potential seed productivity of orchid flowers. The energetic provision for this intensification in orchids was obtained as a result of the strong economization of the whole reproductive process under the conditions of a decrease of the visitation frequency. This is the main characteristic of the reproductive strategy in the orchids studied.
Galactic archaeology: mapping and dating stellar populations with asteroseismology of red-giant stars

Our understanding of how the Galaxy was formed and evolves is severely hampered by the lack of precise constraints on basic stellar properties such as distances, masses, and ages. Here, we show that solar-like pulsating red giants represent a well-populated class of accurate distance indicators, spanning a large age range, which can be used to map and date the Galactic disc in the regions probed by observations made by the CoRoT† and Kepler space telescopes. When combined with photometric constraints, the pulsation spectra of such evolved stars not only reveal their radii, and hence distances, but also provide well-constrained estimates of their masses, which are reliable proxies for the ages of the stars. As a first application we consider red giants observed by CoRoT in two different parts of the Milky Way, and determine precise distances for �2000 stars spread across nearly 15,000 pc of the Galactic disc, exploring regions which are a long way from the solar neighbourhood. We find significant differences in the mass distributions of these two samples which, by comparison with predictions of synthetic models of the Milky Way, we interpret as mainly due to the vertical gradient in the distribution of stellar masses (hence ages) in the disc. In the future, the availability of spectroscopic constraints for this sample of stars will not only improve the age determination, but also provide crucial constraints on age-velocity and age-metallicity relations at different Galactocentric radii and heights from the plane.
THE IMPACT OF PROCESS INNOVATION AND REAL BUSINESS CYCLES THEORY Hiroaki Izumi and Katsuhiko Takahashi Graduate School of Engineering, Hiroshima University

The shockwaves from the September 15, 2008 Lehman Brothers collapse continue, with share prices still falling globally. Our position, however, is that the real economy is more important than financial markets. This paper addresses the cause of the current recession from a real-economy perspective. It does this with an analysis of real business cycles (RBC) theory using a new log(log(x + 1) + 1)-type utility function rather than either the log or constant relative risk aversion (CRRA) ones. Using the RBC theory with a new utility function enables us to demonstrate that the progress of process innovation leads to a transition from supply to demand constraints in developed such economies as those in the United States and Japan, and that weak demand in those countries, even without demand saturation, has caused the current recession. Our use of this function has also led to such previously impossible findings as a strict formulation of involuntary unemployment and the existence of business cycles. This paper demonstrates that utility functions’ shapes affect whether they find that progress in process innovation results in increased or decreased hours of labor. Furthermore, although both process and product innovation give companies advantages, their impact on overall economies are different.
The protective effect of Glutaraldehyde in the extraction of EPS from biofilms

The extraction of the exopolymeric matrix is a prerequisite to properly study the composition of the biofilm. Several extraction methods were already developed, however no universal method has yet been adopted because the compromise between high yields of extraction and minimum cell lysis is difficult to establish. In fact, most of the extraction methods promote leakage of intracellular material. The most common extraction methods, Dowex resin and sonication, where assayed in biofilms of Pseudomonas fluorescens and Alcaligenes denitrificans submitted to a pre-treatment with glutaraldehyde (GTA). The assessment of ATP released after extraction was used as a criterion of cell lysis. The results showed that GTA is a protective agent against cell lysis. The pre-treatment with GTA is particularly useful combined with sonication.
MENTAL HEALTH MORBIDITY IN INDUSTRIAL POPULATION OF SOUTH INDIA

BACKGROUND: The existing literature on mental health in an industrial population is very limited. This study will certainly add to the existing information on planning preventive and promotive measures in industrial population thereby safeguarding their health. AIM: This cross sectional study was undertaken during the November and December month of 2001 in industrial population of a iron ore processing unit of Karnataka, India to study the epidemiology of mental health in industrial population and the associated risk factors. MATERIALS AND METHODS: This study was conducted in an Iron Ore processing company located in Chickamagalore District of Karnataka in the year 2001 (November and December) using Mini International Neuropsychiatric Interview Plus and Occupational Stress Index. 252 employees from 1537 population of Kuduremukh Township were selected as the study sample, which represents 16.4% of the total population of industrial workers. 235 were responders (93.3%) and 17 were non-responders (6.7%). Following a detailed interview with the selected industrial workers, diagnosis was made based on International Classification of Diseases-10, Classification of Mental and Behavioural Disorders: Diagnostic Criteria for Research. RESULTS: Majority of the study sample consists of males (95.7%), Hindus (85.5%), married persons (96.2%), and originally from the state in which industry is located, i.e., Karnataka (96.2%). In the present study current prevalence of depressive disorder is 6.8%, dysthymia being 5.5%. Lifetime prevalence of mood disorder is 17.8% major depression in 7.6%. In the present study there were 59 cases without comorbid diagnoses Vs 26 cases with two or more comorbid diagnosis. Overall 31% cases had comorbid diagnosis. In the present study however no significant difference emerged between those with and without lifetimes or current psychiatric illness in variables such as sociodemographic characteristics, type of work perceived, work related problem and physical health problem. CONCLUSION: Overall the present study has found high rates of psychiatric (lifetime and current) in industrial workers in keeping with western and few recent Indian studies. But has failed to find a robust association
The influence of isolation stress on the (re)organization of cell walls in protoplasts of in vitro recalcitrant plants

A study of cell-wall regeneration was conducted on protoplast cultures of four recalcitrant plant species: yellow lupin and grasspea (grain legumes), and also hyacinth and asparagus (ornamental monocots). The rate of cell wall resynthesis was investigated together with the arrangement of cellulosic fibers on the surface of protoplast-derived cells. Localization of arabinogalactan proteins in cell walls was also performed. Quick cell wall renewal occurred in grasspea and hyacinth cultures, where the percentage of protoplast-derived cells after 24h of culture accounted for 45-50%. In contrast, the presence of cell walls in half of the population was not observed in asparagus and lupin cultures until 5 and 7 days later, respectively. Grasspea, hyacinth and asparagus cells budded intensively. Moreover, the cellulosic material of the cell wall was disorganized and unevenly distributed in lupin, asparagus and hyacinth. In all the tested species arabinogalactan proteins (AGPs) were detected mainly in spherical cells with condensed cytoplasm, but were absent in the budding cells. Notwithstanding the observed differences among species, we concluded that incorrect cell wall structure/composition, together with a deregulated cell cycle might contribute to protoplast recalcitrance in the examined plants. Abnormalities could be a result of the isolation process itself and defective stress-recovering mechanisms. Subsequently, these could arrest regeneration competences and direct cells at apoptotic pathways.
New Implementation of MM-Wave Heterodyne Receiver Based on Six-Port Technology: Circuit Characterization and High Data-Rate Demodulation Results

This paper presents a new implementation of a millimeter wave heterodyne receiver based on six-port technology. The six-port circuit is designed using three hybrid couplers H-90 ◦ and a new ring power divider. For the characterization of the circuit, several six-port two-port measurement configurations were designed and fabricated on the same wafer along with calibration standards. The new six-port architecture evaluation based on qi points location demonstrates wideband performances and high coupled-port phase and amplitude balance in the 57-65 GHz frequency band. The six-port model based on S-parameter measurements is then implemented in ADS software, for realistic advanced simulation systems of a short-range 60 GHz wireless link. The millimeter wave frequency conversion is performed using a six-port down-converter. The second frequency conversion uses conventional means due to the low IF frequency value. The demodulation results of a V-band QPSK signal for high data rate from 100 to 1000 MBits/s are presented and discussed. The results of the Bit Error Rate (BER) analysis demonstrate that the proposed architecture can be successfully used for high speed wireless link transmission at 60 GHz.

Intelligent Information Retrieval Approach using Discrete Wavelet Transform for Holy Quran in Smartphone Application

Answering mobile users’ queries intelligently is one of the significant challenges in information retrieval (IR) in intelligent systems. Current popular Quranic retrieval application ranks the document by counting the occurrences of each of the terms and ignoring any other information in the document to solve the Verses of Quran retrieval problem. Considering the proximity between the query terms assists in the efficiency of ranking results and increases IR performance. The Spectral-Based Information Retrieval Model (SBIRM) considers the query terms’ proximity by examining the term patterns that occur in the documents. To do this, SBIRM utilizes term signal representation and discrete wavelet transform (DWT). In this paper, we solve the Verses of Quran retrieval problem by proposing a novel document model, termed the Dynamic Document Model with Discrete Wavelet Transforms (DDMDWT). The DDMDWT exploits the variations in Verses of Quran length and mathematical transforms for document representation. The proposed model will enhance the existing term signal concept by additionally taking into consideration differing lengths of Verses of Quran. We designed and implemented an intelligent Quranic retrieval (IQR) Android application. In this IQR, the DDMDWT model contributes to reducing the time complexity of SBIRM and decreasing the index size by 20.98%, all while achieving improvement in precision, recall, F-measure, and MAP with compared to SBIRM. This paper also demonstrates how the DDMDWT model delivers a notable increase in the precision of the P@1 and P@3.
Influence of propylparaben on vitellogenesis and sex ratio in juvenile zebrafish (Danio rerio).

The aim of the study was to evaluate the xeno-oestrogenic potential of propylparaben in vivo using zebrafish (Danio rerio). Experimental juvenile zebrafish (20 days post hatching) were fed a feed containing 500, 1000, or 2000 mg kg-1 of propylparaben, fish in a positive control group were given a feed treated with 20 mg kg-1 of 17-oestradiol, and the control fish were given the feed free of either tested substance. The exposure of fish to propylparaben did not affect vitellogenesis after 20 days exposure but seemed to influence the sex differentiation processes, as evidenced by a sex ratio significantly skewed towards females in the group fed 500 mg kg-1 of propylparaben following 45 days of exposure. The potential of the fish to respond to oestrogenic stimulation was confirmed, since significantly higher vitellogenin concentrations were detected in the fish from the positive control group.

Exact Partition Functions of Interacting Self-Avoiding Walks on Lattices

Ideas and methods of statistical physics have been shown to be useful for understanding some interesting problems in physical systems, e.g. universality and scaling in critical systems. The interacting self-avoiding walk (ISAW) on a lattice is the simplest model for homopolymers and serves as the framework of simple models for biopolymers, such as DNA, RNA, and protein, which are important components in complex systems in biology. In this paper, we briefly review our recent work on exact partition functions of ISAW. Based on zeros of these exact partition functions, we have developed a novel method in which both loci of zeros and thermodynamic functions associated with them are considered. With this method, the first zeros can be identified clearly without ambiguity. The critical point of a small system can then be defined as the peak position of the heat capacity component associated with the first zeros. For the system with two phase transitions, two pairs of first zeros corresponding to two phase transitions can be identified and overlapping C υ can be well separated. ISAW on the simple cubic lattice is such a system where in addition to a standard collapse transition, there is another freezing transition occurring at a lower temperature. Our approach can give a clear scenario for the collapse and the freezing transitions.
Evaluation of the diets formulation type on performance of Arian broiler breeder hens

A study was conducted to determine the effects of diet formulation type on broiler breeder performance of 50 to 64 weeks of age. Three hundred and thirty six (336) female and 48 male breeders in eight treatments with six replicates (seven females with a male) were used in the form of a randomized trial design 2×2×2 factorial. Eight experimental diets were formulated based on three factors: first factor included two levels of apparent and true metabolizable energy corrected for nitrogen (AMEn and TMEn) of feed, the second factor included two levels of total amino acids (TAAF) and digestible (DAAF) of feed and the third factor included two levels of broiler breeder hens requirements based on total amino acids (TAAR) and digestible (DAAR). The results show that egg weight was significantly different which was affected by diets formulation based on energy (P 0.05). Treatment 3 (AMEn+DAAF+TAAR) was at the best level significantly different in egg weight 68.97 (g), egg production 62.45%, egg mass 43.1 (g/hen/day) and feed conversion ratio 3.59 (P<0.05). Hatching eggs and hatchability was significantly different, which was affected by diet formulation based on energy, amino acids of feed and requirements (P<0.05). This experiment shows that the type of formulation of diets had significant effects on broiler breeder performance. Keywords: Broiler breeders, performance, digestible amino acids, fertility.

Functional Screening of Plant Genes Suppressed Salt Sensitive Phenotype of Calcineurin Deficient Mutant through Yeast Complementation Analysis

Understanding salt tolerance mechanisms is important for the increase of crop yields, and so, several screening approaches were developed to identify plant genes which are involved in salt tolerance of plants. Here, we transformed the Arabidopsis cDNA library into a salt-sensitive calcineurin (CaN)-deficient (cnbΔ) yeast mutant and isolated the colonies which can suppress salt-sensitive phenotype of cnbΔ mutant. Through this functional complementation screen, a total of 34 colonies functionally suppressed the salt-sensitive phenotype of cnbΔ yeast cells, and sequencing analysis revealed that these are 9 genes, including CaS, AtSUMO1and AtHB-12. Among these genes, the ectopic expression of CaSgene increased salt tolerance in yeast, and CaStranscript was up-regulated under high salinity conditions. CaS-antisense transgenic plants showed reduced root elongation under 100 mM NaCl treatment compared to the wild type plant, which survived under 150 mM NaCl treatment, whereas CaS-antisense transgenic plant leaves turned yellow under 150 mM NaCl treatment. These results indicate that the expression of CaS gene is important for stress tolerance in yeast and plants.
