Abstract: Marek’s Disease (MD), caused by Marek’s Disease Virus (MDV) which is a highly contagious oncogenic and neuropathic disease of chickens. It is responsible for great economic losses to the poultry industry all around the world and characterized by development of CD4+T cell lymphomas as well as infiltration of nerves and visceral organs by lymphocytes. MD is one of the most common lymphoproliferative diseases of chickens which cause mononuclear cell infiltration in one or more of the following tissues: peripheral nerves, gonads, lymphoid organs, iris, muscle, skin and other visceral organs resulting into development of tumors in visceral organs, paralysis of legs, wings and neck, grey eye (iris) or irregular pupil, vision impairment, blindness, skin lesions and immunosuppression, all of which can be accompanied by non-specific signs such as anorexia, weight loss and poor performance. Thus MD poses a big challenge to the welfare and wellbeing of the poultry with increased condemnation of carcass, loss of productivity and quality products, leading to huge economic losses. It is also an immunosuppressive disease and causes increased susceptibility to other infections. The present review discusses in brief about the Marek’s disease, its etiology, conventional and advance tools and techniques being used for its diagnosis, prevention and control strategies in poultry.

Abstract: This study has tackled the theme of responsibility accounting impact on evaluating performance of the Sudanese industrial enterprises. The study specifically investigated how to apply the responsibility accounting system on industrial enterprises and its impact on evaluating the performance as well as comparing the actual performance to the planed performance by using planning budget system. The importance of the study stems from the role of accounting of responsibility in detecting deviations and identifying those responsible along with preparing reports for taking sound decisions. The aim of this study is to figure out the impact of responsibility accounting system on evaluating performance of the Sudanese industrial enterprises, finding the relationship between them and the efficiency of the performance of the Sudanese industrial enterprises, as well as the relationship between responsibility accounting and planning budgets in the optimal use of resources available in the Sudanese industrial enterprises. The study followed both the deductive approach, the inductive method, the historical approach, as well as the theoretical descriptive approach in its theoretical and applied study. The study end up with several conclusions, the most important of which is that responsibility accounting assists industrial enterprises to upgrade their efficiency and effectiveness in exploiting their resources by dividing them into responsibility and supervision centers. The study also provides appropriate methods for measuring and evaluating performance, a matter which increases efficiency of performance. One of the most important recommendations of this study is the need to use responsibility accounting as an audit tool to evaluate performance of industrial enterprises, and the need to figure out deviations and analyze them to determine the causes of their occurrence for taking the necessary measures to correct them in a timely manner.

Abstract: Vegetables have been known from ancient times as fresh and edible parts of herbaceous plants. They play vital role in maintenance of health and help in prevention from a number of diseases. Vegetables have been main source of carbohydrates, vitamin and mineral. Vegetables can be available in different edible forms such as roots, stems, leaves, fruits and seeds. Each edible group have its own contribution. Cucumber is cultivated all around the world and held an important position in cucurbitaceous crops. Seeds of cucumber have cooling, tonic, diuretic and anthelmintic effect. There were total 12 different varieties and central devoutness of the study was to compare all these varieties and to know about the best variety among all. After comparing means from data it was conducted that in terms of days of germination, the fastest germination rate was observed that three varieties C-571, Cucumber Vega and Desi cucumber respectively followed by C-3429 and remaining varieties showed almost same trend, but the variety which took highest number of days to germinate was C-574. All the varieties showed almost similar trend in length of stem and days of flowering. C-3479 possessed highest number of fruits and Sialkot local had lowest number of fruits. Three varieties C-571, 574 and C-3429 exhibited highest yield. The biggest size of leaf was variety WANDRI-700. This study revealed the germination rates and the fastest germination rate was observed that three varieties C-571, Cucumber Vega and Desi cucumber. In terms of Numb of leaves C-3479, C-571 and Sialkot local beard highest number of leaves.

Abstract: The aims of this research were to assess the trends and practices of university students in regular physical activity program, the case of Woldia University. The main objective of the study was to assess the trend and practices of university students in regular physical activity program. The study was conducted using a sample of 45 students by using multi-stage sampling technique with the presence of purposive, stratified and simple random sampling technique, (24 females; 21 males) that are attending third year in Woldia University, Faculty of natural and computational science. The results showed that university students were very well informed about the importance of regular physical activity and sport. Nevertheless, when it came to their involvement in various sporting activity, the questionnaire and observation checklist showed that almost 71% of university students do not generally spend their time participating in any regular physical activity/sport. On the other hand, there is a difference between male (61.54%) and female (38.46%) students in terms of participation on regular physical activity/ sport. The main problems that hindered the participation of university students in physical activities/ sport, almost 47% of students have insufficient time to participate with in academic reason and the others that most students do not participated with having lack of interest in regular physical activity/ sport (28.125%). Based on the university students thought that gave awareness to all departments, management of time with sport, make sport fields safe enough and fulfill enough amounts of fields and equipment for all types of sport will develop students participation in regular physical activity/ sport.

Abstract: To improve the road handling and passenger comfort of a vehicle, a suspension system is provided. An active suspension system is considered to be better than the passive suspension system. In this paper, 2 degrees of freedom of a linear quarter car active suspension system is designed, which is subject to different disturbances on the road. Since the parametric uncertainty in the spring, the shock absorber, mass and the actuator has been considered, robust control is used. In this paper, H and µ- synthesis controllers are used to improve the driving comfort and the ability to drive the car on the road. For the analysis of the time domain, using a MATLAB script program and performed a test using four disturbance inputs of the road (bump, random, sinusoidal and harmonic) for the suspension deflection, the acceleration of the body and the body travel for the active suspension with the H controller and active suspension with µ- synthesis controller and the comparative simulation and reference results demonstrate the effectiveness of the presented active suspension system with µ- synthesis controller.

Abstract: In this paper, we approach used in the original paper, which improved the image contrast of the histogram is based on informal we represent. The source of the original histogram using the histogram below with reference to the brightness level and a limited range of the mean and variance improves. As a final total weighted images obtained histogram is consistent with the Uniform Building. By the range of the minimum and maximum values of each individual operator draws the histogram equalization is limited. We use in this method, the matrix obtained from the histogram method. The histogram of the image without using the histogram of uniform methods and Using the histogram method improves the overall image is described and finally we will compare these two methods.

Abstract: The longitudinal distribution and seasonal fluctuation of phytoplankton communities was studied along the headwaters to stream outlet of a regulated river system, Huai River, China. To determine longitudinal changes in phytoplankton composition and biomass in the Huai River (China), single water parcels were followed from their upstream to estuary during in May, June, September and December in 2011. Diatoms formed the majority of cells in most sections, with green algae second and cryptomonads third in importance. Among the diatoms, centrics were relatively more abundant at upstream reaches and downstream reaches of the river. Phytoplankton biomass increased sharply in the middle part of the river (LK, XCK, BBZ sections), and the decreased down reach at the downstream reaches of the river. In contrast, there was lower algal biomass value at WJB section and higher in nutrient concentrations (NH4-N, TP). In the main channel, small centric diatoms (Melosira), pennate diatoms (Synedra, Fragilaria) were dominant from December to March. A mixed community of chlorophyta (Eudorina elegans, Pandorina morum, and Pediastrum), flagellates (cryptophyceae), cyanophyta (Microcystis, Oscillatoria), and centric diatoms (M.granulata, M.granulata var. angustssima f.spiralis) were dominant in June. In September (the late summer season), the large diatoms (Melosira, Synedra) were dominated, being a large diatoms community phrase, accompanying with blue-green algae (Planktolyngbya subtilis, Oscillatoria and Pediastrum. Melosira. granulata. Phytoplankton dynamics and species selection in regulated rivers may be controlled by discharge-related factors; such as confluence of major tributaries and Bengbu dam, and the results showed that dams had a strong influence on ecohydrological conditions.

Abstract: In this dissertation the high velocity impact behavior of the ceramic/composite and aluminum/composite plates were investigated. With the use of finite element method the perforation and energy dissipation mechanisms of the mentioned plates were determined. The existing analytical model which is applied to find optimum ceramic/composite plates was reviewed. With the use of optimization method the optimum plate which has maximum energy absorption capacity and minimum weight was determined. In this optimization process the responses of the plates were determined with the use of finite element method and the response surface method was applied to construct the approximate optimization functions and constrains. A genetic algorithm optimization method was applied to find the optimum thicknesses of ceramic and composite layers, respectively. Finally the presented optimum plate and the optimum solutions which have been extracted from analytical models were compared.
