Researches regarding the toxicology of saccharin

Saccharin, first synthesized in 1879, eventually became popular as an inexpensive substitute for sugar, particularly as a non-caloric sweetener. The dispute is concerning the safety of saccharin itself. In this article, the history concerning the uses of saccahrin and the accompanying controversy is reviewed. A benefit-risk evaluation for saccharin showed few, if any documentable benefits from the use of saccharin and much genuine uncertainty concerning the potential risks for ingestion by man. This element of genuine uncertainty as to the extent

Research regarding the frequency of AB0 blood groups in a population of pupils from Piatra Neamt, Neamt County

Part of a larger study regarding the genetic polymorphisms present in the human population of Romania, we have studied the frequency of AB0 blood groups in Piatra Neamţ, Neamţ county, at a population of 320 pupils, born between 1992-1997. As controle were used data obtained from Blood Transfusion Centre from Neamţ county, determination made between 2008-2009. The obtained frequencies were concordant with values obtained at Blood Transfusion Centre, which are normal for the romanian population and for Europe. We are discussing various reasons for the slight regional differences of the AB0 blood group frequencies registered between different romanian regions

Irrigation, a Component of the Sustainable Agriculture in North Western Romania in the Context of the Climate Change UDK 631. 67 : 551. 583 (498)

  The paper is based on the researches carried out during 1976-2010 in the long term trial placed on the prelvosoil from Agricultural Research and Development Station Oradea. The main field crops of the area (wheat, maize, sunflower, soybean, bean, potato, sugarbeet, alfalfa) were studied. Based on the soil moisture determination ten to ten days, the soil water reserve was maintained between easily available water content and field capacity on the watering depth. Pedological and strong pedological drought (the decrease of the soil water reserve on watering depth bellow easily available water content, bellow wilting point respectivelly) were registered every year. The use of the irrigation determined the improve of the water/temperature+light (Domuta climate index) report, the increase of the daily and total water consumption, yield gains very significant statistically, the improve of the yields stability and yields quality, the increase of the water use efficiency. The use of the good soil management didn’t worsen the soil structure and the chemical  and biological parameters of the soil were improved. The researches sustain the irrigation opportunity for sustainable agriculture in the North-Western Romania
