Mechanisms and transition structures for conjugate and carbonyl addition of ammonia to three small alpha,beta-unsaturated carbonyl compounds. An ab initio molecular orbital study
(ELSEVIER SCIENCE BV, 2001)
Transition structures for the addition of ammonia to s-cis and s-trans acrolein, methyl vinyl ketone, and 2-butenal have been located with ab initio molecular orbital calculations. Optimization of the geometries of reactants, ...
The rodent fauna from the Adapazari pull-apart basin (NW Anatolia): its bearings on the age of the North Anatolian fault
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2001)
To the east of the Sea of Marmara, the North Anatolian fault (NAF) branches into two strands, namely the northern and the southern strands. The Adapazari pull-apart basin is located in the overlapping zone of the Dokurcun ...
Effect of ketanserin administration on intraocular pressure
(KARGER, 2001)
Purpose: We evaluated the effect of oral single-dose (20 mg) ketanserin on intraocular pressure (IOP) in normotensive and hypertensive eyes. Methods: This study included 15 healthy volunteers and 16 patients with ocular ...
Delta(m)-Statistical convergence
(INDIAN NAT SCI ACAD, 2001)
In this paper, we define a general sequence space Delta (m) (X) = {x = (x(k)) : (Delta (m) x(k)) is an element of X}, (m is an element of N), where X is any sequence space. We establish some inclusion relations, topological ...
Prevention of postoperative adhesion formation in rat uterine horn model by nimesulide: a selective COX-2 inhibitor
(OXFORD UNIV PRESS, 2001)
BACKGROUND: Pelvic surgery is one of the main causes of intraperitoneal (i.p.) adhesions that create various medical problems including pelvic pain, bowel obstructions and female infertility. A rat model was used to ...
Serum free carnitine and total triglycerid levels in children with iron deficiency anemia
(VERLAG HANS HUBER, 2001)
Iron deficiency anemia and hyperlipidemia are common public health problems in Turkey. The connection between iron and lipid metabolisms has not been clarified yet. The aim of the study was to determine the effect of iron ...
An alternative method for the exact calculation of Wannier-Stark localization in superlattices
(ACADEMIC PRESS LTD, 2001)
We present an alternative method for the exact calculations of the Wannier-Stark (WS) localization in a long periodic potential corresponding to a (50 Angstrom /30 Angstrom) GaAs/Ga0.7Al0.3As superlattice. We show that the ...
Do not underestimate atrial septal defect!
(EDIZIONI MINERVA MEDICA, 2001)
Atrial septal defect (ASD) is one of the simplest cases among the surgically correctable congenital cardiac diseases. Easiness of the correction usually causes underestimation of the pathology. Angiography as well as ...
An investigation of keto-enol tautomerism in N-vinyl-2-, and 3-pyrrolidinones using ab initio and density functional theory calculations
(ELSEVIER SCIENCE BV, 2001)
We investigated the protomeric tautomerism of N-vinyl-2-pyrrolidinone (N-V2P) and N-vinyl-3-pyrrolidinone (NV3P) molecules, and considered the three neutral tautomers for NV2P (1a, 1b, 1c) and the five for NV3P (2a, 2b, ...
Beta-human chorionic gonadotropin and prolactin assays in cervicovaginal secretions as a predictor of preterm delivery
(WILEY, 2001)
Objective: To evaluate and to compare the predictive value of cervicovaginal beta-hCG and prolactin levels in spontaneous preterm delivery. Methods: The preterm labor group and normal pregnancy group consisted of 17 and ...
