Influence of some amino acids on the dynamic swelling behavior of radiation-induced acrylamide hydrogel
(HUMANA PRESS INC, 1999)
The influence of some amino acids-alanine, glycine, valine, glutamine, histidine, phenylalanine, and tryptophan-on the swelling behavior of acrylamide (AAm) hydrogel prepared by gamma-radiation was investigated. Swelling ...
Direct calculation of CO-factored force constants from (CO)-C-12-O-16 stretching frequencies in LM(CO)(4) molecules with C-3 nu symmetry
(ELSEVIER SCIENCE SA, 1999)
The CO-factored force constants for LM(CO)(4) molecules having C-3v symmetry were calculated using the relations k(1) = alpha(3 lambda(1) + lambda(2) + 8 lambda(3)), k(2) = 3 alpha(lambda(1) + 3 lambda(2)), k(c)= 3 ...

Hydrogen bonding and dimeric self-association of 2-pyrrolidinone: An ab initio study
(KLUWER ACADEMIC PUBL, 1999)
Ab initio calculations on the different associated structures of 2-pyrrolidinone with water and with itself were carried out using 3-21G and 6-31G(*) basis sets at the Hartree-Fock level, including electron correlation ...
Review of groundwater pollution and protection in karst areas
(KLUWER ACADEMIC PUBL, 1999)
Karst groundwater (the water in a karst aquifer) is a major water resource in many regions of some countries. Water requirements for most of the settlements in the karstic regions are supplied from karst aquifers. Karst ...
Effect of insulin therapy for diabetic cystopathy - Urodynamic and histological findings in a rabbit model
(INFORMA HEALTHCARE, 1999)
Objective: To investigate the efficacy of insulin therapy in preventing cystopathic changes in diabetes using a rabbit model. Materials and Methods: Twenty-four New Zealand white rabbits were studied in three groups: eight ...
Laboratory experiments on the investigation of the effects of sulphuric acid on the deterioration of carbonate stones and surface corrosion
(KLUWER ACADEMIC PUBL, 1999)
In this study, the effect of sulphuric acid, the major constituent of acid rain, on carbonate stones has been investigated. For this purpose, samples from historical buildings of Sivas city have been collected. The ...
Supression of cardiac parasympathetic functions in patients with right hemispheric stroke
(BLACKWELL SCIENCE LTD, 1999)
Objectives: The aim of this study was to investigate the relationship between sympathetic and cardiac parasympathetic function and the side of the lesion in stroke patients. Methods: Thirty-two patients with stroke and 29 ...
Right-sided hiatal hernia of the oesophagus
(SCANDINAVIAN UNIVERSITY PRESS, 1999)
At chest radiography performed for recurrent pneumonia in a 3-month-old boy, an air-fluid level in the right cardiophrenic angle was found and initially perceived as a lung abscess. Upper gastrointestinal tract radiographs, ...
Electric field dependence of the excitonic properties in graded double quantum wells
(IOP PUBLISHING LTD, 1999)
A quasi-bound state approximation is used to obtain the electric field dependence of the eigenvalues, eigenfunctions, electron-hole overlap integrals and excitonic binding energies for coupled, graded double quantum wells ...
