In this paper, a Lotka-Volterra model with time delay is considered. The stability of the equilibrium of the model is investigated and the existence of Hopf bifurcation is proved. Numerical simulations are performed to justify the theoretical results. Finally, main conclusions are included.

In recent years according to the increase of the organizational justice and the effects of the that in results of the organizational systems in case of the reaching the goals and keeping the systems, it took different models and patterns and created new challenging system in order to prevent failing and collapsing and keep system away from dangers which are caused by fast environmental alters, though recent experiments are about checking the effect of the understandings from the organized justice based on the publican fund of the Tejarat Bank’s employees . for this experiment about 4 theories are designed which are in case of the gathering information and ideas from Fernandez questionnaire 2006 and Publican fund questionnaire 1390 which in the end a 46 questions in form of a questionnaire has been formed and given among the Tejarat Bank employees which according to the normal grade of the alters and independency of mistakes and fouls from regression for experiments of theories and from analyzing experiment and toki in grading of organized justice alters in SPSS19 software as results showed up that organized justice and it’s alters which conclude distributive justice , has positive and useful effects on the publican fund of the employees and also grading the organized justice alters showed up that distributive justice comes in the first place and procedural justice comes after it means the second place and in the end interactional justice took the third place of our grading system .

This paper examines twenty-three factors considered important in the selection and patronage of hotels by university lecturers in Abia State, Nigeria. Data were conveniently collected from 285 lecturers in the two government-owned universities in Abia State using self-administered questionnaire containing twenty-three choice statements. Principal component analysis reduced the twenty-three choice items to four factors namely, servicescape, service innovation, spatial layout and service quality. Data were analyzed using ANOVA and multiple regression. The results show that the four factors are important determinants of the choice of hotels by university lecturers in Abia State. Hotel owners and managers were therefore advised to continuously improve servicescape, service innovation, spatial layout and service quality of their hotels for sustainable customer selection and patronage.

This study is to establish the procedure of cleaning validation of Losartan Potassium tables on pharmaceutical manufacturing equipments and analytical method validation by UV spectroscopy. This study develops a procedure and validation analytical method by UV spectroscopy used in cleaning validation. This study is aimed to produce a simple and validated method by UV Spectrophotometer for cleaning validation and develop a system as compliance to the regulatory bodies like USFDA, MHRA, WHO, etc. The method gave good results as compared to official books and guidelines. The analysis of samples by UV is easy as compared to other sophisticated instruments like HPLC, TC. Samples are analyzed effectively by UV Spectrophotometer.

The fact that attendance has a positive effect on the performance of students has been studied by many researchers. This paper provides some evidence on the assumption that the subject of finance requires more teacher-student interaction than the subject of management. Thus attendance and academic performance has more strong relationship for finance than for management subjects. The 170 responses collected from students were analyzed through OLS technique. A stronger positive relationship of attendance and performance was found for Finance as compared to Management. The findings can be applied for other subjects, keeping in view the technicality and non-technicality of the subjects. The limitation in the research has been the variability in the personality of teachers and also the students, which can be very difficult to measure correctly and thus the finding can be different in different scenarios.

Image segmentation is an essential but critical component in low level vision image analysis, pattern recognition, and in robotic systems. It is one of the most difficult and challenging tasks in image processing which determines the quality of the final result of the image analysis. Image segmentation is the process of dividing an image into different regions such that each region is homogeneous. The problem of segmenting the image and/or the video content into meaningful pieces of information is of crucial importance for further steps such as 3-D shape reconstruction, object and event recognition, etc. Video segmentation is different from segmentation of a single image. While several correct solutions may exist for segmenting a single image, there needs to be a consistency among segmentations of each frame for video segmentation. Various image segmentation algorithms are discussed. Some examples in different image formats are presented and overall results discussed and compared considering different parameters.

To determine whether vitamin E and omega-3 supplementations could increase saliva production and reduce oral dryness, 60 patients with oral dryness received either vitamin E (n=30) or omega-3 (n=30) in a three month prospective clinical trial. There was a significant saliva volume increase in vitamin E group (p<0.001) before and after taking the supplementation; However no significant saliva volume change was seen in omega-3 group (p=0.999). In this study vitamin E supplementation was found to be significantly better than omega-3 and significantly effective to improve oral dryness.

The operation of a business enterprise affect a wide spectrum of society. The resources that are used not only limited to those of the proprietors but also from many connected with the enterprises - the share holders, the suppliers of material resources, the consumers, the local community and the society at large.

Indian economy has been growing at the rate of 8-9% during the last three years thus placing it in the top ten economies in the world. According to one estimate India will be the third largest economy by 2012. Another indication of growing India’s international visibility is the growing number of Indian multinational companies in the area of software services, Information Technology, ITES, Biotechnology, Pharmacy, Finance, Petroleum, iron and steel, retail and services. It means more and more companies will open their production facilities and offices outside India. Indian companies have to see as to what styles of management are appropriate in their global operations.
