Wind Power Plants in Interconnected System Modelling with PSS / E

Electricity production from wind energy as a renewble source has been increasing more rapidly than the other sources. In this case effects on the electric power system of wind energy system connection to the electricity network should be investigated As it is known that, connection point of wind energy system to the electricity network has some problem s such as energy quality and electricity network interaction. This is due to the fluctuation on wind speed and variable wind power generation. These disturbance s restrict wind turbine connection to the electricity network espacially at the weak parts of the electricity network. Because short-circuit currents, powers and voltage levels in the transmission system must be within a certain limits. In this study, a case wind power plant(WPP) located in the Western Mediterranean Region of Dinar has been modelled by using PSS/E software also analysis of short circuit currents and load flow analysis have been performed.The analysis showed requirements for the short circuit currents, powers and voltage levels acoording to the international standards, TEIAS and EPDK s.
Farrowing progress ( chronopart ) and enzootic neonatal diarrhoea : observational study in nine commercial herds

In some area of France, almost 20% of the farms are concerned with enzootic neonatal diarrhoea (END) (Sialelli et al., 2009). Onfarm investigations conclude that many diff erent bacteria such as Clostridium perfringens type A, Clostridium diffi cile, Enterococcus durans and others may be isolated but not consistently (Gin, 2008). Our hypothesis is that END origin at the sow level. The aim of this study was to describe the parturition in herds with END in comparison of herds without END.
Market Potential Analysis of E–Rental Business for Travel Equipments in Thailand การวิเคราะห์ศักยภาพทางการตลาดของธุรกิจให้เช่าอิเล็กทรอนิกส์ส�าหรับอุปกรณ์ การเดินทางในประเทศไทย

Travel overseas is a beneficial activity to explore new experience and different cultures. There are necessary several expenses that travelers have to pay for their overseas trips such as accommodations, airfare, local transport and dining etc. Moreover, cost of travel equipments including oversized luggage, seasonal clothes and accessories are added cost. It is not value for money to spend for these equipments which are needed only a short period of time. Thus, it is an idea to start up a rental business of travel equipments via the Internet in Thailand to fulfill untapped needs of budget and infrequent travelers who have quality concerns. In this paper, the concept of sharing economy is critically discussed. Besides, 7Ps of the service mix is thoroughly reviewed in data analysis. The objective of this study is to explore market potential and possibility of this business. A quantitative method is carried out via online questionnaires to gather information about customer needs and business environment for strategic planning of the E–rental business. In addition, some entrepreneurs of rental businesses concerning travel equipments are interviewed to enhance the understanding of consumer behaviors. The findings indicate that there is a limited business potential. However, an enormous size of target market and other significant factors sufficiently make this business attractive to SME entrepreneurs or investors. The business offers a new option of equipment service for travelers. It provides a unique experience with a service standard. To be successful, the business requires a proper strategy to attract prospective customers and compete against competitors or substitute products in the online rental service.

Effect of vitamin C supplementation on some productive and physiological parameters in laying hens

Two hundred and sixteen Hy-Line laying hens were used to study the effect of vitamin C supplementation during summer months on some productive traits, egg quality, plasma and yolk total lipids and cholesterol. The results showed that pullets treated with vit. C had lower (P<0.001) egg production rate and significantly higher (P<0.001) egg weight and egg mass. In addition, their eggs were characterized with significantly higher (P<0.001) absolute and proportional weights of albumen and yolk. Significant improvements (P<0.05) in shell quality estimated as weight and shell weight per unit surface area (SWUSA) was attained with vit. C supplementation. Dietary vit. C supplementation showed highly significant effects on feed consumption and conversion. Pullets of control group had the better feed conversion when compared with those supplemented with vit. C. Plasma calcium and inorganic phosphorus increased in vit. C supplemented birds. Plasma calcium significantly increased (P<0.01) as the time passed reaching its maximum value at the end of the experiment. Plasma total lipids content was significantly lower (P<0.001) in controls and in pullets fed 400 g/ton vit. C, the latter had significantly the lowest value of plasma cholesterol content. Dietary vit. C supplementation decreased yolk total lipids Egyp. J. Nutr. and Feed, 2(Special Issue) 646-664. 647 and cholesterol, the rate of decrease was positively correlated with the level of vit. C supplemented. Significant (P<0.01) positive correlation was noted between egg production and each of plasma calcium and cholesterol. Inverse relationships were found between yolk cholesterol and each of plasma total lipids and cholesterol. Positive highly significant (P<0.01) regression coefficients were found for most studied traits on plasma calcium. Egg production, egg weight, shell, albumen and yolk weights increased by 2.9 egg, 0.89, 0.15, 0.42 and 0.30 g, respectively for unit change in plasma calcium. The results obtained demonstrate that ascorbic acid supplementation can be effective in reducing egg cholesterol and has influences on egg quality.
THE RELATIONSHIP BETWEEN SELF-IMAGE AND PRODUCT-IMAGE AS A BASE FOR CONSUMER SEGMENTATION 1

The problem of relationship between the selfimage and the brand image is relatively old. The first investigations originate into the 60’s (Grubb, 1965). The topic is still important enough, because in today’s highly competitive environment the meaning of distinctive image is common. But the image of a product and especially brand image is most important. Namely: as products become more complex and the marketplace more crowded, consumers rely more on the product’s image than on its actual attributes when making their purchase decisions (Schiffman, Kanuk, 1994).

Perspectives on Nuclear Structure and Scattering with the Ab Initio No-Core Shell Model

Nuclear structure and reaction theory are undergoing a major renaissance with advances in many-body methods, strong interactions with greatly improved links to Quantum Chromodynamics (QCD), the advent of high performance computing, and improved computational algorithms. Predictive power, with well-quantified uncertainty, is emerging from non-perturbative approaches along with the potential for new discoveries such as predicting nuclear phenomena before they are measured. We present an overview of some recent developments and discuss challenges that lie ahead. Our focus is on explorations of alternative truncation schemes in the harmonic oscillator basis, of which our Japanese--United States collaborative work on the No-Core Monte-Carlo Shell Model is an example. Collaborations with Professor Takaharu Otsuka and his group have been instrumental in these developments.
Impact of Cultural Heritage Site Attributes to the Tourist Satisfaction in Zanzibar Stone Town , UNESCO World Heritage Site , Tanzania

The paper focuses on the assessment of the impact of cultural heritage site attributes to the satisfaction of tourists in cultural heritage destinations using the case study of Zanzibar’s Stone Town, UNESCO’s World Heritage site in Tanzania. It involved giving credits to each of the attributes found in the site and tourists had to select the most impressive attributes they encountered. The need for this study is based on the fact that many studies on cultural heritage resources in Tanzania have until recently concentrated on the archaeology, management and conservation of the heritage, thus leaving out issues of tourist satisfaction in general. Data was collected through questionnaires and the sample size included 105 tourists who visited Zanzibar’s Stone Town. The findings show that tourists can be satisfied more by one site attribute than the others due to some issues including inter alia, site maintenance, hygiene and sanitation. The article recommends that the hygiene and sanitation of the town should be improved. It is also argues that there should be a rapid maintenance for example, of some attributes in the House of Wonders Museum, in order to increase satisfaction levels of the tourists visiting this unique UNESCO World Heritage site.
The Effect of 5-FU on the Expression of TGF – β1 in Cultured Tendon Cells

Objectives: This study investigated the effect of the treatment with 1 min exposures to 5-fluorouracil (5-FU) on the expression of Transforming Growth Factor – Beta 1 (TGF-β1) in cultured tendon cells. Methods: Fibroblasts cultured from the flexor tendons of dog paws were treated with 3 different doses of 5-FU (control, 515-25 mgr /ml) for 1 minute. After 5-FU exposure the expression of TGF-β1were tested by real time Reverse TranscriptasePolymerase Chain Reaction (RT-PCR) at 3rd and 7th days. Results: There were no statistically significant differences in the expression levels of the TGF-β1 gene between the control group and all other groups on day 3 and 7 (p>0.05). However, when the percentage changes in the TGF-β1 gene expression on days 3–7 were compared, there were statistically significant differences and this was maximally observed with 89% +12 (p<0.05) in the group treated with 25-mg/ml 5-FU. Conclusions: We conclude that 1 min. 5-FU application maybe sufficient to prevent adhesions in tendon healing by limiting the expression of TGF-β1.
FPGA area time power estimation for DSP applications

Fast prototyping of complex applications such as digital signal processing systems over Field Programmable Gate Array technology has become a very important issue due to the increasing number of FPGA components and their recent architecture evolutions. A rapid estimation of FPGA utilisation rate, time execution and power consumption (ATP in the following) at the behavioral level is necessary to allow an eÆcient exploration of a large design space and to select the best implementation component. The method described here aims at guiding the design process of heterogeneous architectures such as in the codesign issue, so the main quality of the performance estimator is to be fast and accurate enough in order to explore a wide design space and guaranty the choice of the best implementation solution. A lot of estimation techniques are described in the literature and many of them come from the High Level Synthesis (HLS) research. We can nd methods estimating the processing unit [1][3][4], from the behavoral until the layout level, control or memory units [2] for one or two sort of constraints, area and time most of the time. But few techniques targets FPGA and to our knowledge, there is no global estimation methods (i.e. estimating the ATP cost of the whole system) starting from a behavioral speci cation. In [5], the method is set up on the estimation of area and timing values starting from a Register Transfert Level netlist resulting from a HLS tool. This approach aims at speed up the HLS ow by getting rid of the Partitionning, Placement, Routing and Timing optimization steps, and estimating the physical design characteristics instead. The method is very accurate but has two main drawbacks caused by the use of a HLS tool : it might be too slow in the case of the exploration of a wide design space such as in codesign, and the estimation process is strongly dependant of the technology used. Our estimation process allows both to be fastest (to the detriment of accuracy) and far less dependant of the technology through the characterization of the target FPGA in a component library. Furthermore, FPGA power consumption estimation is included in order to give a complete characterization of the design. The outline of this paper is as follow : In section 2, an overview of the estimation ow is presented. Then section 3 explains the speci cation model and resources allocation algorithm whereas section 4 describes the technology caracterization le and ATP mapping process. Finally, preliminary results and a conclusion are given.
Insulin resistance , inflammation and metabolic syndrome in normal weight and overweight / obese primary school children in Kuala Lumpur

Introduction: Studies on metabolic syndrome (MetS) of children are important in view of rising prevalence of childhood obesity worldwide. This study compares the risks of insulin resistance, inflammation and metabolic syndrome between overweight/obese (OW/OB) and normal weight (NW) children in Kuala Lumpur. Methods: A cross-sectional study was conducted in 12 primary schools selected using multi-stage stratified random sampling. Height and weight were taken of a total of 1971 children aged 10-11 years. Based on BMI-for-age, 235 OW/OB children matched for age, sex and ethnicity with 226 NW children were selected for the study. Overnight fasting blood samples were collected to determine insulin, high-sensitivity C-reactive protein (hsCRP), glucose and lipid profiles. Logistic regression analysis was conducted to estimate associations between weight status and metabolic risk factors. Results: Prevalence of MetS among OW/OB children was 3.8% compared to 0% in the NW. Prevalence of insulin resistance among OW/OB was 45.5% compared to 18.6% among NW children. High risk of inflammation was found in 28.1% of the OW/OB children compared to 12.4% in the NW. The odds ratio of having insulin resistance, inflammation and metabolic risk factors among OW/OB were 3.66 (95% CI: 2.40-5.59), 2.76 (95% CI: 1.69-4.50), 4.93 (95% CI: 3.42-7.10), respectively compared to the NW. Conclusion: The OW/OB children in this study showed higher risks of developing insulin resistance, inflammation and MetS compared to the NW counterparts. Further studies are suggested to better understand the relationships between insulin resistance, inflammation and MetS in children.
IEEE 802.11n MAC Mechanisms for High Throughput: a Performance Evaluation

Nowadays IEEE 802.11 standard is the most widely used one in wireless LAN (WLAN) technology. One of the key reasons is the continuous amendments presented by the IEEE 802.11 working group. One of these amendments (IEEE 802.11n) was approved to enhance 802.11 for higher throughput operation. IEEE 802.11n is an ongoing nextgeneration wireless LAN standard that supports a very high speed connection with more than 100 Mb/s data throughput measured at the medium access control layer. In this paper we examine the major improvements introduced by IEEE 802.11n MAC: aggregation, block acknowledgement, and reverse direction. We show the impact of each parameter in the network performance. Keywords-component; IEEE 802.11n; aggregation; block ACK; reverse direction1
Innovative application of frequency response analysis for partial discharge measurement

Measuring partial discharge on transformers and rotating machines requires knowledge of the frequency characteristics of the test object impedance. This allows assessing capacitive or transmission line behavior and localizing resonances. Impedance measurement is a helpful tool to correctly select the coupling capacitor and measuring impedance for optimal sensitivity. In this paper, a method of impedance measurement is presented based on the same frequency response analysis (FRA) equipment used for transformers. The typical decrease with frequency of the equivalent capacitance of transformers and the transmission line behavior of rotating machines are investigated both with simulations and measurements. The impedance measurement gives insight to the electrical behavior of the test object, serves to find resonances and flat sections in the spectrum and therefore provides valuable information for correct PD measurement.
Extending seL 4 Integrity to the Genode OS Framework

In 2011, the seL4 team formally verified that the seL4 microkernel enforces integrity and authority confinement on user-space threads. We extend these guarantees to virtual machine monitors (VMMs) running on the Genode OS Framework, and using seL4 as the underlying microkernel. We will do so by employing a model checking approach using Alloy, and combining the seL4 integrity proofs with our models of Genode and seL4. Our verification effort will show that VMMs cannot manipulate kernel objects for which they lack the necessary permissions, and that no VMM can escalate its privilege beyond what is allowed and interfere with other VMMs running in the system.
Na +-channel antagonists act as electron donors while agonists act as electron acceptors in reactions with dye free radicals

The reactions of Na+-channel antagonists and agonists with dye free radicals were studied by the methods of pulse and continuous absorption spectroscopy. All Na+ antagonists tested except tetrodotoxin act as electron donors while agonists act as electron acceptors in the reactions with photogenerated dye free radicals. Qualitative correlation between electron donor activity of the Na+-channel blockers and their electrophysiological potency was observed. The relation of discovered regularity to the Na+ channel operating was discussed.
DESIGN AND NUMERICAL SIMULATION OF A 3 D VIRTUAL MODEL OF AN ORTHOTIC DEVICE USED FOR PATIENTS WITH OSTEOARTHRITIC KNEE

The knee osteoarthritis is one of the major chronic diseases usually found in people of middle age and old age and also mainly causes various disabilities. Knee osteoarthritis involves a degenerative process of cartilage in the knee joint leading to its loss [1]. Symptoms of OA are associated with altered load distributions across the knee, which cause an increase in the contact pressure on the tibiofemoral joints thereby promoting disease progression [2]. The knee osteoarthritis is one of the major chronic diseases usually found in people of middle age and old age and also mainly causes various disabilities. Knee osteoarthritis involves a degenerative process of cartilage in the knee joint leading to its loss [1]. The most influential factor affecting load distributions across the knee is malalignment. Varus malalignment has been shown to increase OA progression in 70% persons with knee OA [3]. This paper presents the geometric models and numerical simulations for healthy joint and for the joint affected by osteoarthritis (OA) disease with inclination in varus by 5 o , 10 o , 15 o , but, also, for the orthotic device –osteoarthritic knee assemblies for each cases in two variants: initial orthosis and proposed orthosis. The geometric model of the knee joint was obtained from CT images processed with the integrated applications DesignModeler and Space Claim [4]. The Finite Element Method is used to obtain the von Mises maps, the strains maps and the displacements maps. The maximum values of these characteristics for healthy knee and for the three cases of osteoarthritic knee are presented in table 1.
Advertising with Discretionary Search

We examine a market for a search good in which consumers are uncertain about the firm’s product quality, but may search to gather information before buying. We show that credible information can be conveyed to consumers even when the firm faces a market with little or no preference heterogeneity. Rather, differences in willingness-to-pay arise from the endogenous search decisions by consumers. A fundamental assumption is that search is not required for purchase and consumers may bypass it altogether. In this case search induces a dispersion in preferences that is detrimental for the firm’s ability to capture value. This provides an incentive for the firm not to overstate its quality. When quality is common knowledge (but product fit is uncertain before search), increases in quality lead to a higher market price, but firm profits and consumer surplus are non-monotonic because of changes in the search regime. In particular if quality is high enough for search to be worthwhile the firm faces downward pressure in prices and consumers become better off. These effects reverse at higher levels of product quality. Surprisingly, when product quality is unknown but credible information is available consumers become worse off with the probability of facing a high type firm, because this firm prefers to target high value consumers and not serve those who do not find that the product fits their needs. ∗Stanford University, Graduate School of Business, 655 Knight Way, Stanford CA, 94305, USA, gardete@stanford.edu and Hong Kong University of Science and Technology, Kowloon, Hong Kong, China, mkguo@ust.hk, respectively.
EFFECT OF DIFFERENT FEED INGREDIENTS ON GROWTH , SENSORY ATTRIBUTES AND BODY COMPOSITION OF LABEO ROHITA

Comparative studies on effect of different feed ingredients on growth, sensory attributes and body composition of Labeorohita were conducted in fiber glass tanks having dimensions 12 ft x 4ft x 3 ft (length x width x depth) for a period of 3-months. Labeorohita (n = 10), having average body weight 200±2.33g were stocked in each fiberglass tank and were fed @ 4% of total fish biomass. Plant origin feed ingredients viz. guar meal, soybean meal, cotton seed meal and canola meal were used as treatment diets while fishmeal served as control. Each ingredient was considered as a separate treatment and there were three replicates for each of the treatment and control diets. Statistically significant (P≤0.05) differences were observed in growth, FCR and specific growth rates among treatment and control diets. Weight gain was highest in fish fed with guar meal while the same was lowest for fishmeal diets. Although, there were differences in chemical composition of different feed ingredients however, statistically non-significant differences were observed in sensory attributes of fish flesh and the body composition of fish. Statistically, significant (P≤0.05) variations in mineral content viz. Na, Ca, Fe, Zn, and Cu were recorded in fish flesh among treatment and control diets. It can be concluded from present study that plant origin feed ingredients viz. guar meal, soybean meal, cotton seed meal and canola meal can be safely used for feed formulations of herbivorous fish species while guar meal is recommended for better growth performance of Labeorohita.
