Analytical and finite element comparisons of stress intensity factors of composite materials
(Elsevier Sci Ltd, 2000)
In this paper, a comparative study regarding the determination of stress intensity factors (SIF) for non-standard thin composite plates is presented. Carbon-epoxy composite plates are considered for the study. Unnotched ...
Seminal arginase activity in infertility
(Springer Verlag, 2000)
Arginase(Arg) activity in seminal plasma and sperm cells from infertile men and healthy fertile donors was measured. There were no statistically meaningful differences in seminal plasma Arg activity between the two groups ...
Familial cerebellar ataxia and hypogonadism associated with sensorimotor axonal polyneuropathy
(Elsevier Science Bv, 2000)
In this article, we report two siblings who have familial cerebellar ataxia and hypogonadism associated with sensorimotor axonal polyneuropathy documented by light microscopy. This combination has not been reported previously ...
Augmentation of shoulder contour using a calf implant
(Springer-Verlag, 2000)
Sprengel deformity is a rare orthopedic condition that is associated with functional and cosmetic impairment. Results of orthopedic procedures are usually inconsistent and cosmetic results are far from satisfactory in these ...
Failure analysis of two-dimensional carbon-epoxy composite plate pinned joint
(Taylor & Francis Inc, 1999)
The aim of this study is to investigate failure strength and failure mode of a mechanically fastened carbon-epoxy composite plate of arbitrary orientation. The failure load and the failure mode are analyzed numerically and ...

Polymorphism of M factors in populations of the housefly, Musca domestica L., in Turkey
(Cambridge Univ Press, 2000)
M factors, which determine maleness in Musca domestica, were found on the second, third, fourth and fifth linkage groups in housefly populations of Turkey. As in European populations, the male-determining factor was more ...
Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
(Springer, 2000)
Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-me ...
Intramolecular hydrogen bonding and tautomerism in Schiff bases. Part II. Structures of 1-[N-(2-pyridyl)aminomethylidene}-2(1H)-naphtalenone (1) and bis[2-hydroxy-κO–N-(2-pyridyl)-1-naphthaldiminato-κN]zinc(II) (2)
(Elsevier Science Bv, 2000)
The Schiff base ligand (1) and its Zn(II) complex (2) have been synthesized and their crystal structures have been determined. Compound (1) crystallizes in the monoclinic space group C2/c with a = 26.993(2), b = 5.891(1), ...
Effects of high density lipoprotein containing high or low β-carotene concentrations on progesterone production and β-carotene uptake and depletion by bovine luteal cells
(Elsevier Science Bv, 2000)
Luteal cells were isolated from mid-luteal heifer ovaries by collagenase digestion. Cells were cultured with DMEM/Ham's F12 medium in serum pre-treated plastic culture dishes for periods of up to 11 days. As beta-carotene ...
