conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

A complete pH and blood gas analysis of arterial and mixed venous blood may comprise more than forty different quantities. We have selected sixteen, including patient temperature. The arterial oxygen tension group includes the oxygen tension, fraction of oxygen in inspired air, and fraction of mixed venous blood in the arterial (total physiological veno-arterial shunting). The haemoglobin oxyge...

The subject of acid-base balance has become one of increasing complexity over the past two decades. Along with better understanding of the processes involved has come an array of confusing terms and ideas that leaves most physicians completely bewildered. For example, in a recent article on acid-base balance, the author listed six commonly used chemical definitions of the words "base" and "acid...

The acidosis that occurs during clinical anaesthesia was formerly thought to be metabolic in origin because of inefficient carbohydrate breakdown in the unconscious state (Van Slyke, Austin, and Cullen, 1922). More recent authors (Taylor and Roos, 1950; Beecher and Murphy, 1950) have suggested that the acidosis is respiratory, due to defective ventilation, and the present work was undertaken to...

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

the present study has been focused on the acid and base transesterification of animal fats (dairy cow and beef) to produce biodiesel by varying process parameters such as catalyst amount, catalyst nature, reaction time and temperature. the maximum biodiesel yield after acid catalysis was 94.1 ± 2.43 and 98.4 ± 2.3 percent for dairy cow and beef tallow, respectively. the quantity of biodiesel ob...
