Chemical Aspects of Synaptic Excitation
I came to Canberra in February 1971, and as far as I can recall I got very few experimental results before about May—progress at a snail’s pace by the standards of a novice research student. I regretted having turned down offers of scholarships from the UK and Canada, and I felt particularly bitter about a prestigious California institution which, after a very promising initial correspondence, ...
متن کاملChemical composition of indoor ash residues
The ash content formed after burning of materials in indoor may be harmful to environment on dumping due to high ionic and metallic concentration. Therefore, the chemical composition of various indoor ash residues derived from burning of the biomass (BM), coal (C), cow dung (CD), incense (IS) and mosquito coil (MC) materials is described in this study. Three samples each of BM, coal, CD, IS and...
متن کاملChemical composition of smoke produced by high-frequency electrosurgery.
BACKGROUND Exposure to surgical smoke during electrosurgery may be harmful to theatre personnel. This study quantified toxic compounds present and we were particularly interested in isolating toluene, ethylbenzene and xylene due to their putative carcinogenic effects. METHODS A variety of surgical procedures were studied. Smoke samples emitted during electrosurgery were collected in charcoal ...
متن کاملPropagation and Chemical Composition of Ultra High Energy Cosmic Rays
Extragalactic cosmic ray protons with an injection spectrum of the typeE show a spectrum on earth with a dip due to the Bethe-Heitler pair production against the photons of the cosmic microwave background. The dip is produced in the energy region 10 − 4 × 10 eV with position and shape that reproduce with high accuracy the spectrum observed experimentally. This interpretation of the observed dat...
متن کاملChemical Composition of Patikaraparpam
Patikaraparpam, a Siddha formulation in prepared by trituration of potash alum with egg albumin followed by calcinatin. The three authentic laboratories made parpams as well as six commercial samples have been examined for their chemical composition. The analytical data that emerged from the analysis of the above samples showed that seven parpams contained only aluminium sulphate and they did r...
