Effect of added calcium ions on the relative milk clotting activities of porcine pepsin, Mucor miehei protease, Endothia parasitica protease, and Mucor pusillus protease was compared with that of rennin. Skimmilk, maintained at pH 6. 3 with 0.000% to 0.030% added calcium chloride, was used as a substrate. The coagulation activity of Mucor pusillus protease appeared to be most sensitive to calcium ions, followed by Mucor rniehei protease, porcine pepsin, rennin, and Endothia parasitica protease. The clotting activities of Mucor pusillus protease were also more sensitive than rennin to added calcium ions in milk samples maintained at pH values of 6.4, 6.5, and 6.6. Mucor pusillus protease and rennin were standardized to equal activities in skimmilk maintained at pH 6.3 and 6.6 containing 0.020% added CaCl2. For skimmilk maintained at pH 6.3, Mucor pusillus protease concentrations ix that gave the same clotting times as rennin in skimmilk containing 0.000% and 0.010% added CaCl2, were 9.6% and 4.5% higher than its standardized concentration. While at pH 6.6 Mucor pusillus protease concentrations were 13.2% and 5.8% higher.

Farm enterprise diversification is an important tool for agricultural producers with respect to risk management. As agricultural producers in Virginia look to prepare their farm businesses for the new millennium, they are increasingly considering non-traditional enterprises and activities for their farms. As producers add new enterprises, they encounter challenges to develop new skills and gather adequate information for their new activities. Virginia Cooperative Extension has the task of providing producers with timely and useful research-based information. As both producers and Virginia Cooperative Extension agents and specialists prepare for the challenges of the changing face of agriculture in Virginia in the next generation, a mutual understanding of the key factors and motivations for enterprise diversification is necessary. This study investigates the key factors, motivations, and information needs of seven diversified farms in Virginia. The implications for producers and Cooperative Extension are outlined, and recommendations are made for Virginia Cooperative Extension, lenders, and agribusiness. / Master of Science

Consumption of sugar, sugar-containing food and drinks, related health risks and change of life style in our population are currently addressed issues with negative consequences already observed in childhood. The aim of the diploma thesis was to study the consumption of sugar and foods containing sugar in children attending kindergarten and 1st grade of elementary school. The theoretical part was focused on an overview of knowledge about sugars, both naturally occurring and added, and health risks associated with frequent consumption of foods containing added sugars. In the practical part, the consumption of these foods in terms of quantity and various forms and its influence on the development of childhood obesity and other metabolic diseases was monitored. At the same time, other aspects of children's lifestyle that could determine children's obesity were identified. The basis of the practical part was a questionnaire survey using questions determining eating habits of children. The research showed a relationship between the BMI of children above the 75th percentile and more frequent sweets consumption and less frequent active (sports) and natural physical activities. Almost 84% of children consume sugar and sweets more often than 3 times a week, with more frequent consumption in kindergarten...

A research report to be submitted to the Faculty of Commerce, Law and Management, University of Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Commerce( Specialising in Taxation); March 2016 / The present study sought to investigate self-selection among internal and international migrants in Gauteng by making use of the Gauteng City Region Quality of Life Survey data. The present study also sought to disentangle the effects of observed and unobserved characteristics in the self-selection of migrants by conducting Oaxaca-Blinder decomposition on overall employment and self-employment outcome variables. Preliminary descriptive statistics indicated that international migrants experienced markedly higher levels of employment than both locals and internal migrants driven by higher rates of informal and self-employment. System GMM analysis of pseudo panel data confirmed these results and showed that international migrants had a higher probability of employment and self-employment. Oaxaca Blinder decomposition indicated that unobserved characteristics explained the greatest share of the differences in the rates employment and self-employment of locals, internal migrants and international migrants. These results provide evidence for the positive selection of international migrants to Gauteng on unobservable characteristics relevant to the region’s labour market.

The objective of this study was to establish the consumer acceptability of preblended and nonpreblended post rigor seasoned pork patties with added water levels of 0, 3, 6, and 9 percent for each formula. Other parameters measured were proximate analysis, texture, cooking loss, and consumer acceptability. Nonpreblended treatments had a higher (P<0.05) percentage of protein and a lower (P<0.05) percentage of fat as compared to preblended treatments. Texture analysis revealed a lower (P<0.05) amount of total energy required to shear through a single patty in preblended treatments than nonpreblended treatments. No differences (P>0.05) were detected among treatments at varying water levels. Consumer acceptability showed no differences (P>0.05) among selected treatments. Consumer acceptability scores indicated that consumers would consume both preblended and nonpreblended seasoned pork patties at varying water levels.

and keywords New methods of combating VAT evasion The topic of this work is the rating of the current situation regarding value added tax evasions, which rates the situation de lege lata, identifies its shortcomings and proposes de lege ferenda solutions that could prevent or at least reduce such evasions. The theses also shows practical examples and tries to present situations that can actually occur in the environment of taxes. The first chapter is focused at general description and introduction to the topic of value added tax, while it is very briefly explaining its basic design elements. It also outlines the nature of tax evasion. The second chapter focuses on the limits of financial administration, which lie mainly in its limited staffing capabilities. The chapter emphasizes the need for automation and explains its practical benefits, outlining the basic framework of most tools to fight against tax evasion. The third chapter describes specifically the issue of the so-called control report, points out its predominant strengths and presents it as one of the successful tools in the fight against tax evasion. At the same time, however, the shortcomings of the current legislation are rated and de lege ferenda solutions are proposed. The fourth is focused at the issue of the so-called electronic...
