Sixteen weeks of chronic vitamin C deficiency, induced in guinea pigs by restricted vitamin C intake, resulted in a marked increase in the serum total LDL- and VLDL- cholesterol, triglycerides and total lipids. HDL-cholesterol decreased resulting in a highly significant increase in LDL/HDL ratio. The results reconfirm that vitamin C deficiency causes changes in blood lipid profile which could promote atherogenesis.  相似文献

Recent technological advancements in data storage and processing have changed how companies conduct their business. An increasing number of firms have started putting their efforts in extracting information from their databases to improve profitability and reduce costs using quantitative approaches. Thus, the job market has been experiencing a rapidly growing demand for business analytics (BA) practitioners, and universities across the globe are increasingly responding to this newly emerged field by offering both undergraduate and graduate level degrees as well as certificate programs. Thus, this research aims to provide a framework for academic institutions to develop a state‐of‐the‐art master's in business analytics (MSBA) curriculum by identifying concepts, skills, knowledge, and tools (CSKT) that industry seeks in BA practitioners. Our data‐driven methodology utilizes peer institution analysis, indeed.com web scraping, and focus group analysis with mid‐ and senior‐level analytics leaders from major companies. Our contribution to the literature and recommendations to institutions developing MSBA programs are offered at the end.  相似文献

Recent reports on the involvement of calcineurin in cardiac hypertrophy and its susceptibility to free radicals, prompted us to examine possible beneficial effects of dietary antioxidants in this regard. In continuation of initialin vitro studies revealing eugenol to be a potent calcineurin inhibitor, we investigated its ability to reverse isoproterenol-induced cardiac hypertrophy in rats. Intraperitoneal administration of isoproterenol (1 mg/kg body wt/day for 10 days) induced cardiac hypertrophy with increased heart weight and enhanced apoptosis of myocytes concomitant with accumulation of reactive oxygen species, decreased glutathione contents, increased activities of calcineurin and protein kinase C in ventricular tissue. Administering eugenol for 3 days (1 mg/kg body wt/twice a day), followed by combined administration of isoproterenol and eugenol resulted in significant reversal of cardiac hypertrophy and restoration of above changes. These results suggest that eugenol, a natural antioxidant of dietary origin, may offer potential benefits in the management of cardiac hypertrophy.  相似文献

Chemistry behind the life of a transformer   总被引:3,自引:0,他引:3  
Conclusion Scientific assessment of the insulation conditions rather than years of service determine the remnant life of the transformer. Insulation age of a transformer is exclusively decided by the life of cellulosic materials. Extent of degradation of cellulosic materials can be quantified by measuring dissolved CO2 gas content in oil, degree of polymerization of paper and furan content in oil. Transformer life is shortened by a number of events. Taking action to prevent failure from any of these causes is a method of life extension. Maintaining the insulation system in good order and controlling loads by the use of dynamic loading of the equipment make it possible to improve the utilization of the existing transformer capacity.  相似文献

The combination of industrial development, the exponential growth of human settlements and the ever-increasing use of synthetic substances is having an adverse impact on the ecosystem and thus on human health. These chemicals find their way into soil, air, water and food. They are in the tissues of plants, animals and humans. There is very little effective national or international control of the manmade chemicals in current use.  相似文献

Abstract

Higher education is a service that contributes to national development, integration and regional cohesion. Agricultural education in particular has been viewed in many developing countries as a significant contributor to sustainable development and poverty alleviation. In view of its public mandate, higher education in most countries is regulated by competent bodies. However, higher education is also a service recognized under the General Agreement on Trade in Services (GATS) of the World Trade Organization (WTO). It is therefore subject to WTO's essential principles of promoting trade liberalization, market access and equitable treatment to all participants. But very little is known about the consequences of free trade in educational services. Also it is difficult to define which educational services are strictly commercial and which are public services. As a result, application of GATS can lead to disputes, unless the definitions are clear and international standards are in place, as in the case of other WTO agreements such as TRIPS, SPS and TBT. The present paper assesses the implications of application of the provisions of GATS to higher education in general and agricultural education in particular, with respect to Indian regulatory mechanisms for agricultural education. International scenarios of application of GATS in higher education and relevant policy issues for India as perceived by the faculty members of agricultural universities are discussed. The purpose is to initiate a fruitful debate at various national forums that can inform national policy and take advantage of the opportunities provided under GATS, while ensuring that national interests are kept in perspective.  相似文献
