This study examined relationships of job stress, perceived organizational politics and turnover intention among employees using a cross-sectional design. Two hundred and fifty eight (258) non-teaching staff (124 male and 134 females) from the University of Nigeria Nsukka, with a mean age of 42.07 years, SD of 9.59 participated in the study. One hundred and forty six (146) of the respondents were married while sixty four (64) were single and 48 were widows.

The study was design to investigate the effects of overrun and glycerol supplementation on physicochemical properties of probiotic frozen yogurt. Frozen yogurt was prepared containing different types of probiotics (Lactobacillus acidophilus and Bifidobacterium lactis) along with yogurt starter culture (Streptococcus thermophilus and Lactobacillus bulgaricus). In frozen yogurt mixture glycerol in 1.5, 3 and 4.5% concentrations were supplemented and frozen with 60, 80 and 100 % overrun. Frozen yogurt was stored at -20ºC after production and hardening.

Protected Natural Areas (PNA) have represented internationally from more than 100 years ago, a strategy to preserve geographic spaces with an important biological richness, however these reservoirs have not incorporated in its design to the human element, such as an integral part in preservation activities, have dismissed the local knowledge systems, to implement a planning given by the global system.

Entrepreneurship and entrepreneurship education is generally viewed upon as being important for economic growth in the 21st century. Teaching entrepreneurship however seems to need another approach than regular education to fulfill the professional and ever changing needs. In this perspective active learning and constructivism is generally seen as essential. Other elements that are influencing the teaching process are focus on competences, culture, the needs of the student and the curriculum. This emphases’ the design of the curriculum must address these changing demands of society.

The aim of this study was to evaluate the displacement of Mexican sheep production units as a result of imports. The country as a whole was taken as the unit of analysis, the information is mainly obtained from SAGARPA and sectorial agencies, FAO, Ministry of Economy and the Bank of Mexico, the study was conducted from 1970 to 2011. Data was deflated with National Consumer Price Index for the second half of December 2010. The increases/decreases, average growth rate, inventory, production and imports were determined.

The present study was conducted in department of sericulture, University of Agricultural Sciences, Bangalore. The main aim of the study is to know the effect of different organic sources on soil arthropods under rainfed condition. The treatment T6 recorded the maximum abundance of 14.67 arthropods per 400 gm of soil which was on par with T3 (13.67 arthropods/ 400 gm of soil). T5, T4 and T7 recorded on par results. T8 gave lower abundance of below ground arthropods with 5.67 arthropods per 400 gm of soil respectively.

This study presents the first results about the genetic polymorphism and diversity among the five Egyptian Bulinus truncatus populations, Giza (GZ), Damietta (DM), Behera (BH), Fayoum (FY) and lab bred strain (LB), using the inter-simple sequence repeats PCR (ISSR-PCR). A total of 85 bands, unique, polymorphic and monomorphic were obtained using 10 ISSR primers. Out of them, 28 bands were polymorphic. Among B. truncatus populations, the highest polymorphism (57.1%) was revealed by the primer ISSR1, followed by that revealed by ISSR7 (40%).

Aqueous plant extracts of Croton bonplandianum Bail. was evaluated  for their allelopathic effect on  growth and  developmental changes of two rice cultivars(BPT-5204 and IR-20). The plant extracts was applied at 5, 5, 10, 15,20 and 25% concentrations on the seeds of rice cultivars to understand the germination, growth and pigment changes by conducting pot culture experiments.

Mycotoxins play a global role in human and animal health. Molds in poultry feed are a source of significant economic loss to poultry producers. Molds adversely influence performance of animals by altering the nutrient composition of feed ingredients, decreasing the efficiency of nutrient utilization, and by producing toxic secondary metabolites.

Since the advancement of information technology and the development of computers in the 1960s, students’ approaches to design education have been affected greatly in recent years. The current situation of using Computer Aided Design (CAD) in architectural practices through the aid of computer systems for visualisation presentation, communication, and information processing purposes define the future of architectural education in universities and graduates employment opportunities into small to mid-sized companies.
