Effect of austenitization heat treatment on the magnetic properties of Fe-40wt% Ni-2wt% Mn alloy
(Journal Of Univ Of Science And Technology Beijing, 2007)
The effect of austenitization heat treatment on magnetic properties was examined by means of Mossbauer spectroscopy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was obtained by using scanning electron microscopy ...
Children with fractures show higher levels of impulsive-hyperactive behavior
(Lippincott Williams & Wilkins, 2007)
Children with fractures have been reported to have impulsive-hyperactive behavior problems although whether they exhibited such behavior more often than children with other orthopaedic conditions is unknown. We investigated ...
Approximation of functions of two variables by certain linear positive operators
(Springer India, 2007)
We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation ...
Position vectors of a spacelike W-curve in minkowski space E1 3
(Korean Mathematical Soc, 2007)
In this paper, we study the position vectors of a spacelike W-curve (or a helix), i.e., curve with constant curvatures, with spacelike, timelike and null principal normal in the Minkowski 3-space E-1(3). We give some ...
The effect of austenitizing time on martensite morphologies and magnetic properties of martensite in Fe-24.5%Ni-4.5%Si alloy
(Springer, 2007)
The effect of austenitizing time on the formation of martensite in Fe-24.5%Ni-4.5%Si alloy has been studied by means of transmission electronmicroscope (TEM), scanning electronmicroscope (SEM) and Mossbauer spectroscopy ...
Poly[[diaquacaesium(I)]bis(μ 3 -3-carboxypyrazine-2-carboxylato)]
(Int Union Crystallography, 2007)
The asymmetric unit of the title compound, [Cs(C6H3N2O4)(2)(H2O)(2)](n), contains one Cs-I cation on an inversion centre, one 3-carboxypyrazine-2-carboxylate anion and one water molecule. In the crystal structure, each ...
Smart and cationic poly(NIPA)/PEI block copolymers as non-viral vectors: in vitro and in vivo transfection studies
(Wiley-Blackwell, 2007)
In this study, in vitro and in vivo transfection of temperature-sensitive, polycationic poly(N-isopropylacrylamide) and polyethyleneimine copolymers (poly(NIPA)/PE125L) were performed. Copolymer and copolymer-plasmid DNA ...
Prevention of maternal bacterial transmission on children's dental-caries-development: 4-year results of a pilot study in a rural-child population
(Pergamon-Elsevier Science Ltd, 2007)
Aim: Dental caries with its bacterial agent is an infectious disease, and shows a vertical transmission. The control of bacterial transmission of Mutans streptococci (MS) from mother to child has been studied, and its ...
Factors contributing to sex assignment and reassignment decisions in Turkish children with 46,XY disorders of sex development
(Freund Publishing House Ltd, 2007)
Background. Sex assignment decisions for children with disorders of sex development (DSD) should be based on integrative assessments of relevant biological and psychosocial characteristics. Aim: To investigate the factors ...
Electrophysiological evaluation of cremasteric reflex in experimental testicular torsion
(Georg Thieme Verlag Kg, 2007)
Aim: The aim of the study was the electrophysiological evaluation of the cremasteric reflex after experimental testicular torsion. Material and Methods: Ten male Wistar rats were enrolled into the study. Genitofemoral nerve ...
