Energy Absorption and Exposure Buildup Factors of Essential Amino Acids
The effective atomic number and effective electron density in amino acids are of significant interest due to their use in various applications. The energy absorption buildup factors, exposure buildup factors, effective atomic numbers, and electron densities of essential amino acids such as Leucine (C6H13NO2), Lysine (C6H14N2O2), Methionine (C5H11NO2S), Phenylalanine (C9H11NO2), Threonine (C4H9N...
متن کاملA Comprehensive Study on Energy Absorption and Exposure Buildup Factors for some Soils and Ceramic Materials
Abstract: Study of gamma ray energy absorption (EABF) and exposure buildup factors (EBF) for some essential soils, ceramic materials in the energy region 0.015-15 MeV up to a penetration depth of 40 mfp (mean free path). To calculate both EABF and EBF, five parameter geometric progressions (G-P) fitting approximation has been used. Variation of EABF and EBF with incident photon energy, penetrat...

متن کاملA STUDY OF ULTRASONIC ABSORPTION OF SOME AMINO ACIDS AND THEIR MIXTURES AT PHYSIOLOGICAL pH
In this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological pH and 25°C and a concentration of 0.1. M. The absorption of mixtures of some amino acids was also measured. In the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. This...
متن کاملIntestinal absorption of amino acids and peptides.
The aim of this account is to summarize current views on the absorption of the products of protein digestion, amino acids and peptides. Longer reviews of protein absorption (Wiseman, 1968; Matthew, 1969, 1971; Gray & Cooper, 1971) will provide references not given here. Hormonal effects on absorption are reviewed by Levin (1969). Protein digestion is initiated in the stomach by pepsins and cont...
