In order to meet the growing food demand, use of pesticides is a common feature in agriculture now a day but extensive use of pesticide has resulted in global contamination of the environment. Imidacloprid is one of the major representatives of the new generation of neonicotinoid insecticides. The objective of current study is to examine the hematological parameters and developmental defects after exposure of imidacloprid in chick embryos. Present study was carried out on 300 fertile eggs of white leghorn chicken. Imidacloprid exposure increases the risks of developmental defects and mild toxic effects on hematological parameters in chick embryos.

The University of message and specific objectives of teaching, scientific research and community service, they play an important and significant role in the practice of scientific research. The scientific research of the most important pillars of universities, a standard measure of scientific and academic level. The first universities and the natural place to conduct research because of the large number of specialists from faculty members as well as provide search requirements of laboratories and equipment, and the necessary resources for scientific research data collection. The research aims to shed light on the reality of experiments fields in the College of Agriculture and the statement of efficiency usability fields experiments in scientific research and to highlight the shortcomings and weaknesses and their impact on the conduct of the research process of The perspective of professors of the Faculty of Agriculture the aim of identifying determine inhibiting factors and the factors that help in the development of efficient use of the fields and converted of research fields to the research and production for the purposes of development.

Spermatocytic seminoma is a rare malignant tumor of the testis that is characterized by an extremely low metastatic potential. This tumor is distinguished from other testicular germ cell tumors including classical seminoma by histological and immunohistochemical features clean. Previously, it was treated in the same way as conventional seminomas by prophylactic irradiation of para-aortic lymph nodes and iliac after orchiectomy. The currently accepted approach is surveillance. The rarity of this tumor makes diagnosis difficult, but its identification is very important to avoid any further treatment to patients after the initial surgery. We report a case of spermatocytic seminoma in a 42 year old patient and discuss the clinical, diagnostic and therapeutic features of this condition.

Salinity is one of the increasing problems in the world including a wide area of our country. In response to salinity, multiple morphological, physiological and biochemical changes can be created in plants. In this study, Seedlings of Dracocephalum moldavica were subjected to 0, 20, 50, 70 and 100 mM NaCl. Changes in morphological traits, proline content, total phenol and activity of antioxidant enzymes such as peroxidase (POX) and polyphenol oxidase (PPO) in shoot were evaluated. As a result, POX and PPO activities in shoot significantly increased while shoot dry weight decreased progressively. The total amount of the phenolic and free proline also increased after the NaCl treatment. The increase was dose-dependent. The highest amount of free proline achived at 100 mM NaCl which was about 3-fold higher than control in shoot, respectively. higher than control. Our results support the idea that the activities of POX and PPO and accumulation of total phenol and proline is associated with salt tolerance as oxidative responses.

Salt stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses, and ultimately lower crop productivity in arid and semi arid zones. To better understand salt stress responses in crop plants, we compared effects of salinity stress on growth, chlorophyll content and osmotic components in cresses that were grown in controlled environment in Hoagland nutrient solution containing 0, 5o, 100, 150 and 200 mM NaCl, respectively. Proline, soluble carbohydrates, chlorophyll ‘a, b’ and carotenes of leaves were determined 30 days after initiation of salinity stress. The results reveal that salinity caused significant decreases in growth of cress plants as measured by fresh weight. By increasing NaCl levels from 0 to 200 mM, the content of chlorophyll a and b, and carotenes reduced. Maximum reduction was observed at 200 mM of NaCl. Mean values of data showed that Lepidium sativum had the maximum reduction of chlorophyll a and b, and carotenes under salinity stress. In this study, salinity had no significant effect on soluble carbohydrate but the proline content varied among the cresses whether the plants were grown with or without salinity stress.

Finding Shortest path in a graph has been the area for many researchers. Shortest path is one of the fundamental and most widely used concepts in networks. Here, we discuss the Shortest Path Length (SPL) from a specified vertex to all other vertices in a network. For illustration, a real life example has been considered from Chennai to kanyakumari roadways transport network.

Evaluation of student’s performance is one of the most important responsibilities of every educational institute. The marks obtained by the students in examination should not be the only criteria to decide academic excellence. In this paper, aims to discuss the study of the student’s performance by including the Intelligence quotient (IQ). Here the fuzzy matrices are used to find the level of performance of the students. The fuzzy logic is used for finding the academically excellent student.

Life Insurance is important for everyone to protect family incase of their demise the insured money will save their family. Our objective of this paper to find out the peak age of people interested to take insurance policy and when they mostly use the benefits in their policy period. It has been classified into six benefitst. To study this problem, they divided and defined four types of matrices. Now we use this model to study of the people interested to take insurance policy and when they mostly use the benefits in their policy period.

Nestle is one of the world’s largest and most prominent food companies. Headquartered in Vevey, Switzerland, it was established in 1866 by Henri Nestle. In this article the authors attempted to identify the various problems encountered by the Nestle dealer and to ascertain the group of (based on product variants) worst affected by such problems.

In this paper, a medical image watermarking algorithm based on contourlet is proposed. Medical image watermarking is a special subcategory of image watermarking in the sense that images have special requirements. Watermarked medical images should not differ perceptually from their original counterparts because clinical reading of images must not be affected. Watermarking techniques based on wavelet transform are reported in many literatures but robustness and security using contourlet are better when compared to wavelet transform. The main challenge in exploring geometry in images comes from the discrete nature of the data. In this paper, original image is decomposed to two level using contourlet and the watermark is embedded in the resultant sub-bands. Sub-band selection is based on the value of Peak Signal to Noise Ratio (PSNR) that is calculated between watermarked and original image. To extract the watermark, Kernel ICA is used and it has a novel characteristic is that it does not require the transformation process to extract the watermark. Simulation results show that proposed scheme is robust against attacks such as Salt and Pepper noise, Median filtering and rotation. The performance measures like PSNR and Similarity measure are evaluated and compared with Discrete Wavelet Transform (DWT) to prove the robustness of the scheme. Simulations are carried out using Matlab Software.
