On the commutative neutrix product of distributions
(INDIAN NAT SCI ACAD, 1999)
Let f, g be distributions in D' and let f(n)=f * delta(n), g(n)=g * delta(eta), where {delta(eta)} is a certain sequence converging to the Dirac delta-function. The neutrix product f square g is said to exist and be equal ...
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 ...
Serum-free carnitine levels in children with heart failure
(OXFORD UNIV PRESS, 1999)
The serum-free carnitine (SFC) levels of 91 children with heart failure (HF) and of a control group consisting of 30 healthy children were measured, Twenty-four of 91 children with HF were administered oral L-carnitine. ...
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 ...
Adsorption mechanisms of phenol and methylphenols on organoclays
(MULTI SCIENCE PUBL CO LTD, 1999)
Eight clay-organic complexes were synthesized by placing quaternary ammonium cations (QUATs) on to bentonite (B) and kaolinite (K) by cation exchange. The organic cations used were hexadecyltrimethylammonium (HDTMA), ...
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, ...
