Effect of thiazide drug compound on the testicular protein and cholesterol contents of albino rat

In this study the effect of thiazide diuretic compound on the protein and cholesterol contents in the testes of albino rats as the experimental model. The drug thiazide was administered orally daily for 10,20 and 30 days at the dose of 100mg/kg body weight. Total protein decrease in the testes of rats were evidenced may be due to the side effects of thiazide drug compound which is linked with the hyponatremia and protein metabolism. An elevated level of cholesterol contents observed in thiazide treated rats also revealed that the side effect of drug compound thiazide and also may be due to the stimulation of catecholamine which is stimulated therefore, the biochemical estimation such as protein and cholesterol in the testes after the thiazide treatment determined the effectiveness of diuretic drug compound would provide clinical evidences of their side effects.     

Sands modeling constrained by high-resolution seismic data

In the phase of field evaluation, the changing of interwell reservoir may be out of control if the geological model was built only on well data due to few existing wells. The uncertainty of the interwell reservoir interpolation based only on well data can be decreased by comprehensive utilization of geological, logging and seismic data, especially by using highly relative seismic properties from 3D seismic data adjusted by well point data to restrict interpolation of geological properties. A 3D-geological model which takes the sand body as the direct modeling object was built through stacking the structure, reservoir and water/oil/gas properties together in 3D space.

Free-Space Optical communication using visible light

INTRODUCTION A growing and seemingly insatiable bandwidth demand in the marketplace is bring Free-Space Op- tical (FSO) technology into the carrier space as a means of broadband access for closing the “last mile” connectivity gap throughout metropolitan networks. Terrestrial short-range FSO systems which are gen- erally point-to-point links between buildings on the campus or different buildings of a company can be used to setup wireless communication networks or to supplement radio a…     

整数规划中精确罚函数的一般形式

In this paper, the general exact penalty functions in integer programming were studied. The conditions which ensure the exact penalty property for the general penalty function with one penalty parameter were given and a general penalty function with two parameters was proposed.     

Silent or Stealth Retractions,the Dangerous Voices of the Unknown,Deleted Literature

Retractions serve as one perspective of the publishing process, and can offer vast insight into the problems associated with basic research, with the traditional publishing platform, or with policies. Some established retraction guidelines exist, such as those established by the Committee on Publication Ethics, or COPE. This essay provides a perspective of stealth or silent retractions within the broader concept of retractions, and within the framework of the COPE retraction guidelines. The issue of opaque retraction notices, especially in the case of COPE members, as well as the prominence of questionable retraction policies among select “predatory” open access publishers, is emphasized. Select clear examples are provided.     

The Global/Local Book Publishing (R)evolution

In the decades since the Second World War, interest in Western-style children’s books has expanded in tandem with the growth of a literacy-minded global middle class. Now, as publishing for young people takes root for the first time in nations as economically and culturally diverse as Mexico, Saudi Arabia, and China, the opportunities for rights exchanges, co-editions, and other forms of industry cooperation across national and cultural borders are greater than ever.
