متن کاملStudies on Endothelial Reactions
1. Experimental cerebral and meningeal tubercles in the rabbit are formed from cells of endothelial origin. 2. These cells are derived apparently from other sources than the neighboring capillary endothelium alone. 3. The circulating macrophages, which, in this case, are capable of multiplying by mitosis while still free in the blood, are drawn upon in the formation of the cerebral tubercle. 4....
متن کاملCharacterization of pore coking in catalyst for thermal down-hole upgrading of heavy oil
Heavy oil and bitumen are a potential alternative energy source to conventional light crude. However, recovery of these resources can have substantial environmental impact. Downhole upgrading offers the prospect of both improving recovery, and decreasing environmental impact. However, use of catalysts to enhance downhole upgrading is limited by the need for one that can survive the extreme coki...
متن کاملTheoretical studies on cycloaddition reactions
Cycloaddition reactions represent one of the most powerful processes in organic chemistry. The most common types of cycloaddition reactions are the Diels-Alder (DA) and the 1,3-dipolar cycloaddition reactions (1,3-DCs) which lead to five and six membered rings, respectively. In our ongoing efforts to contribute to the understanding of DA and 1,3-DCs; we studied the following using the B3LYP/6-3...
