MatLab Simulink Modeling for Network-Harmonic Impedance Assessment: Useful Tool to Estimate Harmonics Amplification

The importance of the subject is given by the fact that harmonics are making their pres- ence felt in electrical distribution networks, and the cheapest and most widespread solu-tion for power factor correction is the capacitor banks. This chapter proves that the harmonic impedance is an efficient tool for assessing the state of distribution networks containing harmonics. The unfavorable operating conditions are anticipated based on the network harmonic impedance values, and the means of intervention are selected. Harmonic impedance monitoring and using it in expert systems for operating condition optimization will increase in the future. Power factor correction by shunt capacitor switching in electrical networks containing harmonics can lead to harmonics amplifica- tions by harmonic voltage increasing and capacitors thermal overstressing by great values of the currents flowing through them. This chapter proposes a method for practical determination of harmonic impedance. Based on its values, a quick method is developed to anticipate the harmonic voltages and current amplifications that can occur when a shunt capacitor is installed for power factor correction. Amplification factors are calculated depending on the equivalent harmonic impedance of the network seen in the com- pensation bus. A distribution network containing harmonics is modeled using MatLab Simulink, and harmonic impedance is determined by simulation in different operating conditions. Using the values of the harmonic impedance and the capacitive reactance of the capacitor bank that is connected for power factor correction, the amplification of the harmonic voltages and currents is estimated by calculus. The results obtained by calculus are then compared with the values obtained by simulation after the connection of the capacitor bank to the network. In conclusion, the chapter proves that the network harmonic impedance is a useful tool to estimate the harmonics amplification caused by power factor correction using shunt capacitor banks.
Studying the properties of galaxy cluster morphology estimators

X-ray observations of galaxy clusters reveal a large range of morphologies with various degrees of disturbance, showing that the assumptions of hydrostatic equilibrium and spherical shape which are used to determine the cluster mass from X-ray data are not always satisfied. It is therefore important for the understanding of cluster properties as well as for cosmological applications to detect and quantify substructure in X-ray images of galaxy clusters. Two promising methods to do so are power ratios and center shifts. Since these estimators can be heavily affected by Poisson noise and X-ray background, we performed an extensive analysis of their statistical properties using a large sample of simulated X-ray observations of clusters from hydrodynamical simulations. We quantify the measurement bias and error in detail and give ranges where morphological analysis is feasible. A new, computationally fast method to correct for the Poisson bias and the X-ray background contribution in power ratio and center shift measurements is presented and tested for typical XMM-Newton observational data sets. We studied the morphology of 121 simulated cluster images and establish structure boundaries to divide samples into relaxed, mildly disturbed and disturbed clusters. In addition, we present a new morphology estimator - the peak of the 0.3-1 r500 P3/P0 profile to better identify merging clusters. The analysis methods were applied to a sample of 80 galaxy clusters observed with XMM-Newton. We give structure parameters (P3/P0 in r500, w and P3/P0_max) for all 80 observed clusters. Using our definition of the P3/P0 (w) substructure boundary, we find 41% (47%) of our observed clusters to be disturbed.
A Study of Genetic Structure of Rutilus frisii kutum in Anzali Lagoon, Using Microsatellite Markers

Kutum ( Rutilus frisii kutum ) is regarded as one of the valuable aquatic species in Southern Caspian Sea. Previous reports have indicated that there are two different forms of this fish in the Caspian Sea, the spring-run and the autumn-run. Despite high importance of availability of knowledge around the subject, there is yet no genetic study carried out on the fish’s population structure. A number of nine microsatellite loci were employed in the present study to investigate the genetic variation and differentiation between spring- and autumn-run of the species in Anzali Lagoon. For the purpose, genomic DNA from 105 specimens from springand autumn-run kutum from Anzali Lagoon and as well from Khoshkrud spring-run fish were extracted, and PCR amplification performed. A total of 149 alleles were detected at the 9 loci across the 3 populations (Anzali spring- and autumn-runs as well as Khoshkrud springrun). Khoshkrud population exhibited a lower allelic and genetic variation (A= 5, Ho= 0.406 and H e= 0.612) than the populations at Anzali Lagoon, and in spite of the higher number of alleles per locus (5.8) as well as higher observed heterozygosities (0.606) in the autumn-run in comparison with the spring-run (5.7, 0.571) in Anzali Lagoon, the differences weren’t found as significant (P � 0.05). Both Fis value and significant deviation from Hardy–Weinberg Equilibrium (HWE) in all the cases (9 loci × 3 populations) indicated a deficit in heterozygosity. The highest population differentiation was found between Anzali spring-run and Khoshkrud run (Fst = 0.119, P� 0.01) and the lowest (Fst = 0.07, P� 0.01) between Anzali spring- vs. autumn-run. The highest genetic distance (D= 0.337) was observed between Anzali autumn-run and Khoshkrud whereas it was found to be the lowest (D= 0.25) between the spring- and the autumn-runs in Anzali. The obtained data suggested that the spring and autumn-runs of kutum in Anzali Lagoon should be considered in the studies and enhancement programmes of this species in the Caspian sea.
Analysis and Programming of Kernel for Embedded Systems

In this study, we present a miniOS kernel implemented via analysis of the context switching, the scheduler, and the memory management of the original OS kernel for an embedded system based on ARM core. Since this is a large subject, we have limited our scope to them only that made up an embedded operating system. The implemented miniOS kernel is composed only by them, to the exclusion of all other functions of the original kernel. Our goal is to modify the OS kernel depending on the product function. The implementation method of the miniOS kernel can be applicable to any OS being mounted based on the ARM core. Modifying the kernel depending on the product function can improve the OS booting speed as well as save the system memory. The functions of the scheduler, the context switching, and the memory management are described with the source in each section. The miniOS kernel was implemented in the Assembly and C language and was verified through the build and the test. The results are shown in the Section 5.
Ephrin B 3 ( EphB 3 ) receptors expressed in spinal tissue of rats with spinal cord injury

Ephrin (Eph) receptors are the largest family of receptor tyrosine kinases (RTKs) and their membrane bound ligands, The Eph plays an important role in formation of spines with normal morpholog and synaptic plasticity. However, the Eph receptors expression in spinal tissue with spinal cord injury (SCI) was unclear to have little regarding molecular studies; thus, the present study aims to investigate changes from EphB3 receptors in spinal tissue of rats with injured spinal cord on mRNA level and protein level by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and western blot, respectively. It was found that EphB3 receptors were significantly up-regulated in SCI group in comparison to the control group on mRNA level. On protein level, EphB3 receptors were also highly increased in SCI group compared with control group. These results suggested that decreased EphB3 expression might also become a potential target in the treatment of SCI in future.
Characteristics of Eucheuma cottonii waste from East Malaysia: physical, thermal and chemical composition

ABSTRACT The aim of this paper was to examine the characteristics of Eucheuma cottonii waste in order to analyse its potential as renewable material. The morphology of Eucheuma cottonii (raw and wastes) was investigated through scanning electron microscopy (SEM), the thermal behaviour through thermogravimetric analysis (TGA) and the physical properties through FT-IR, XRD, gas pycnometer, particle size analyser, water absorption and moisture content analysis. The chemical compositions were determined by using acid detergent fibre (ADF), neutral detergent fibre (NDF) and acid detergent lignin (ADL) analysis. It was found that Eucheuma cottonii wastes have better thermal stability, higher crude fibre content, lower moisture content and similar density to the raw Eucheuma cottonii, which suggests that these biomass wastes have good potential as renewable filler material.
A Study on Strategic Industry Selection by Analysis of Inter-industry Network: The Case of Korea

In order to maximize the efficiency of the economic activation policy through fostering specific industries, it is important to prioritize the industry and it is necessary to understand the inter-industry network. We obtained an inter-industry network from the recent inputoutput table in Korea and analyzed the structure of the same. In addition, we analyzed various index values provided from the inter-industry analysis and the network theory for each industry. From the results of the network analysis, it is expected that the chemical and metal industries, transportation machinery industry, and some service industries will have a great impact on the downstream industries. It is expected that more precise strategy design model could be 1 developed through agent-based simulation of economic dynamics.
Fast Track or Failure: A Study of the Graduation and Dropout Rates of Ph.D. Students in Economics

This paper presents an analysis of the failure and completion rates of graduate students in economics at three universities in The Netherlands. We find that an indicator of the research productivity of the supervisor is an important determinant of the completion and dropout rates. However, this effect seems due to the fact that supervisors with a good research record attract and select better students. There is no evidence of an independent effect of having a supervisor who is an active researcher.
Foraminifera Biostratigraphy and Depositional Environment of Sediments in SILE Well, Offshore Dahomey Basin

The sedimentary succession penetrated by the SILE Well offshore Benin republic in the Dahomey basin has been investigated for biostratigraphy and paleoenvironment of deposition. This section consists from the base to the top of sandstone overlying by shale measuring a total thickness of approximately 2000m. Twenty samples of shale were selected and processed for Foraminiferal study. The result of micropaleontological analysis reveals moderately rich and diverse microfauna of planktic and benthic foraminifera totalling 78 species altogether. 64 species (82.6%) are calcareous and 14 species (17.9%) are arenaceous. Of the calcareous forms, benthics accounted for 45 species (70.3%) while planktics accounted for 19 species (29.7%). Two major Planktic biostratigraphic zones were identified: The Morozovella subbotinnae zone, Morozovella vellascoensis and an Undiagnostic zone suggesting a Late Maastrichtian to Early Eocene interval. Based on the recovered benthic foraminifera, Haplophragmoides sp. , Bulimina marginata, Eponides pseudoelevatus, Karreriella bradyi, Hopkinsina hourqi, Cibicidoides pseudoungerianus, Gyroidinoides girardanus, Lenticulina grandis, Oridorsalis umbonatus, Karreriella bradyi and Bathysiphon sp.suggests a depositional environment ranging between outer neritic and upper bathyal. Integration of biostratigraphy and depositional environment suggests that the sediment were deposited within Late Maastritchtian to Early Eocene interval with 3 major biostratigraphic zones in generally shallow marine environment ranging from outer shelf to upper bathyal with water depth not deeper than 300m.
The Effect of Aripiprazole versus Risperidone on Prefrontal Brain Metabolite Levels and Brain Volume in Psychotic Disorders: An Exploratory Study

Abstract Objective: Given that aripiprazole acts as a partial agonist on the dopamine receptor, it may have unique effects on brain neuro-metabolism, specifically in the prefrontal cortex. In this exploratory study, we investigated the effect of aripiprazole compared to risperidone on prefrontal metabolite levels (Glx, NAA, Creatine, Choline and myo-Inositol) and changes in gray and white matter volume (GMV and WMV) in patients with a psychotic disorder. We hypothesized that patients treated with aripiprazole would show increased levels of Glx and NAA and preserved brain volumes, in contrast to risperidone. Methods: In this randomized, single blind study, patients (n=24) treated with either risperidone or aripiprazole underwent magnetic resonance spectroscopy (1H-MRS) and high-resolution anatomical scans (3T) at baseline and after 9 weeks. LC Model was used to determine the absolute spectral metabolite levels and SPM12 was to perform voxel based morphometry analyses. Both metabolite levels and brain volumes were compared between treatment groups. Results: We found a trend for a different effect of both antipsychotics on Glx levels, whereby risperidone reduced Glx levels compared to aripiprazole. Moreover, patients treated with aripiprazole showed a decreased GMV in the precentral gyrus, caudate and lateral frontal regions and increased WMV in the precentral gyrus and a non-significant but consistent pattern of prefrontal WM increases, in contrast to risperidone. Conclusion: Our results point to possibility of different effects of aripiprazole on brain volume and metabolism compared to risperidone. Studies in larger samples are needed to shed more light on the robustness and nature of such differences.
CHANGES IN MECHANICAL PROPERTIES OF MINIMALLY PROCESSED YELLOW PITAHAYA TREATED WITH 1-MCP

The mechanical properties stress of yield limit ( σ L ), modulus of deformability (Ed), failure stress ( σ F ), and Hencky strain at failure ( e HF ), of minimally-processed yellow pitahaya treated with 200 μ gL -1 1-MCP during storage (10±1 °C, 85% RH) was evaluated. Mechanical analysis of the fruit was performed using a stress-strain curve. The samples were subjected to uniaxial compression test at break. The results showed that the samples treated with 1-MCP showed the highest values of stress of yield limit, modulus of deformability and failure stress. This indicates that the application of 1-MCP provides greater firmness to the fruit and may represent an alternative to reduce undesirable changes in texture during storage.
Spatial variability in iron nutritional status of large diatoms in the Sea of Okhotsk with special reference to the Amur River discharge

The Sea of Okhotsk is known as one of the most biologically productive regions among the world's oceans, and its productivity is supported in part by the discharge of iron (Fe)-rich water from the Amur River. However, little is known about the effect of riverine-derived Fe input on the physiology of the large diatoms which often flourish in sur- face waters of the productive continental shelf region. We conducted diatom-specific immunochemical ferredoxin (Fd) and flavodoxin (Fld) assays in order to investigate the spa- tial variability of Fe nutritional status in the microplankton- sized (20-200 µm; hereafter micro-sized) diatoms. The Fd index, defined as the proportion of Fd to the sum of Fd plus Fld accumulations in the cells, was used to assess their Fe nutritional status. Additionally, active chlorophyll flu- orescence measurements using pulse-amplitude-modulated (PAM) fluorometry were carried out to obtain the maximum photochemical quantum efficiency (Fv /Fm) of photosystem II for the total micro-sized phytoplankton assemblages in- cluding diatoms. During our observations in the summer of 2006, the micro-sized diatoms were relatively abundant (> 10 µg C L 1 ) in the neritic region, and formed a massive bloom in Sakhalin Bay near the mouth of the Amur River. Values of the Fd index and Fv /Fm were high (> 0.9 and > 0.65, respectively) near the river mouth, indicating that Fe was sufficient for growth of the diatoms. However, in oceanic waters of the Sea of Okhotsk, the diatom Fd index declined as cellular Fld accumulation increased. These results suggest that there was a distinct gradient in Fe nutritional status in the micro-sized diatoms from near the Amur River mouth to open waters in the Sea of Okhotsk. A significant corre- lation between dissolved Fe (D-Fe) concentration and the Fd index was found in waters off Sakhalin Island, indicat- ing that D-Fe was a key factor for the photophysiology of this diatom size class. In the vicinity of the Kuril Islands be- tween the Sea of Okhotsk and the Pacific Ocean, micro-sized diatoms only accumulated Fld (i.e., Fd index= 0), despite strong vertical mixing consistent with elevated surface D-Fe levels (> 0.4 nM). Since higher Fe quotas are generally re- quired for diatoms growing under low-light conditions, the micro-sized diatoms off the Kuril Islands possibly encoun- tered Fe and light co-limitations. The differential expressions of Fd and Fld in micro-sized diatoms helped us to understand how these organisms respond to Fe availability in the Sea of Okhotsk in connection with the Amur River discharge.
Smoothness criteria in surface wave tomography

SUMMARY We discuss and develop further the methods of surface wave tomography in the frame of the geometric ray approximation. The general approach for determining the lateral phase or group velocity distribution, which is a standard 2-D tomography problem, involves linearization, representation of the unknown function as a series in some basis functions, and evaluation of the coefficients by the methods of linear algebra. If the wave paths cover the area under investigation non-uniformly, the basis functions should not be chosen a priori, but constructed proceeding from the pattern of paths. Different criteria for constructing the basis functions are compared, and a relation between them is considered. A more preferable approach is joint interpretation of phase and group velocity data for different periods, because it allows the information about phase velocity variations to be enlarged due to the use of the group velocity data. Both the phase and group traveltimes are represented as linear functionals of the unknown phase slowness corrections. A specific form of the data kernels allows the basis functions to be represented as a product of two functions, one depending on the horizontal coordinates, and the other on frequency.
A Model for Evaluation of Business Education Programmes

This paper examines a model for the effective evaluation of business education programmes. The model is known as the Kernel of Truth. The paper briefly looked at some definitions of business education and evaluation. It further treated some models in programmes evaluation and Kernel of Truth theory was strongly advocated for use in the evaluation of business education and other educational programmes. Recommendation was made and conclusion drawn . Business education is an educational programme offered in some universities and colleges of education as an undergraduate course of study. Whether conceptualized as broad-aimed or narrow in scope, business education programme requires adequate evaluation to enable to effectiveness of the programme or discrepancies in the programme be ascertained and decision made accordingly. It is a sound educational practice that such evaluation should be built into the programme development processes from the start. Moreover, it is necessary that the evaluation be made simple conceived clearly designed flexibly and imaginative and scheduled realistically. 2. What is Business Education? Although the concept "business education" is frequently used, it is still in semantic flux. Research and theoretical formulations have continued to grapple with the problem of its definition. A generally acceptable definition has been difficult to arrive at because there are as many different meanings of the concept as there are many experts who have tried to define it. Business education is an aspect of educational programme offered at the higher institution of learning which prepares students for careers in business. It is education needed to teach people business in order to be a good citizen of a society. It is a profession of itself. It is education designed with the primary skilled aim of elevating one's skills as well as providing citizens with the required skilled to secure gainful employment as to earn a living and to succeed in life through further education.
Use of molecular marker diversity to increase forage yield in timothy (Phleum pratenseL.)

Molecular marker technologies may provide a tool to overcome the forage yield plateau in timothy (Phleum pratense L.). Therefore, a study was designed to investigate the relationship between marker-based genetic distance (GD) estimates and yield. Genetic distances were estimated using Dice coefficients framed by 28 simple sequence repeat markers. In Experiment 1, parents with high general combining ability (GCA) from two contrasting first-generation synthetic strains (exhibiting high and low yields) were compared. Average GDs of each strain were 0.74 (high) and 0.68 (low). These differences indicated that GD may be partially the basis for contrasting yields. In Experiment 2, GDs among 40 parents of a polycross were used for calculating general genetic distance (GGD), which is indicative of their allelic complementation. Analyses revealed a significant (P < 0.01) moderate correlation (r) between GGD and GCA for yield (r = 0.45) and a significant (P < 0.01) residual mean square for the regression of yield on GGD, suggesting that considerable non-additive effects were associated with GCA. The results are indicative of the potential use of GD estimation for yield improvement in timothy.
Developing Senior Eccleasiastical Professionals ' Emotional and Cultural Intelligence : A Longitudinal Preliminary Case Study Research

ENGLISH) Emotional intelligence (EI) and cultural intelligence (CQ) are constructs that have recently received much attention and have been investigated in work contexts. It is possible that a high EI and CQ both contribute generally to improved intercultural and interreligious understanding and dialogue. However, this relationship has hardly been researched in eccleasiastical contexts in Germany. This study investigates the development of EI and CQ during a 12-day training course for developing intercultural and interreligious competencies for senior professionals in an ecclesiastical context over a period of nine months. Preand post-test scores of EI and CQ were measured during the training period. Besides the quantitative survey, a literature analysis and participant observation in the training course was used for data collection. It was found that with regard to the EI total scores, all dimensions except the dimension of "appraisal of emotions in the self" improved from the beginning of the training until the end. Looking at the preand post-scores of CQ, the scores increased in six participants, and decreased in two. FULL TEXT Headnote
