Genotype-phenotype correlation, gonadal malignancy risk, gender preference, and testosterone/dihydrotestosterone ratio in steroid 5-alpha-reductase type 2 deficiency: a multicenter study from Turkey
(SPRINGER, 2019)
BackgroundStudies regarding genetic and clinical characteristics, gender preference, and gonadal malignancy rates for steroid 5-alpha-reductase type 2 deficiency (5-RD2) are limited and they were conducted on small number ...
Phosphorus-Nitrogen compounds part 47: The conventional and microwave-assisted syntheses of dispirocyclotriphosphazene derivatives with (4-fluoro/4-nitrobenzyl) pendant arms: Structural and stereogenic properties and DNA interactions
(ELSEVIER SCIENCE SA, 2019)
The Cl exchange reactions of hexachlorocyclotriphosphazene, N3P3Cl6, with two equimolar amounts of N-alkyl-N'-mono(4-fluorobenzyl)diamines (1-3), FC6H4CH2NH(CH2)(n)NHR1 (n=2 and 3, R-1=CH3 or C2H5), and N-alkyl-N'-mono(4 ...
Cu-Al-Mn shape memory alloy based Schottky diode formed on Si
(ELSEVIER SCIENCE BV, 2019)
In this work, martensite was made over the wide temperature ranges and the two forms of martensite morphology in Cu85.41Al9.97Mn4.62 shape memory alloy (SMA) were beta' and gamma' martensite phases. The SMA was characterized ...
The effects of seasonal heavy-metal pollution of Ladik Lake on pike fish (Esox lucius)
(TAYLOR & FRANCIS LTD, 2019)
Ladik Lake (Samsun, Turkey) is a natural landscape under the threat of pollution because of urban, agricultural and industrial activities. In this study, accumulation of heavy metals (Al, Ba, Cr, Cu, Fe, Mn, Pb and Zn) in ...
NUMERICAL SOLUTION OF NATURAL CONVECTIVE HEAT TRANSFER UNDER MAGNETIC FIELD EFFECT
(SCIENDO, 2019)
In this study, non-Newtonian pseudoplastic fluid flow equations for 2-D steady, incompressible, the natural convective heat transfer are solved numerically by pseudo time derivative. The stability properties of natural ...
Master's Students' Perceptions and Expectations of Good Tutors and Advisors in Distance Education
(ATHABASCA UNIV PRESS, 2019)
The purpose of this study was to explore non-thesis Master's students' perceptions and expectations of good tutors and advisors in distance education programmes. It also examined whether these perceptions and expectations ...
A Geometric view of Magnetic Surfaces and Magnetic Curves
(INT ELECTRONIC JOURNAL GEOMETRY, 2019)
In the present paper, we approach the magnetic surfaces geometrically. For this aim, we study the problem of constructing a family of magnetic surfaces from a given magnetic field line. We obtain a parametric representation ...
Performance improvement in photosensitive organic field effect transistor by using multi-layer structure
(ELSEVIER SCIENCE SA, 2019)
In this study, a new approach was introduced for Photo-OFETs as a multi-layer structure. Poly(3-hexylthiophene-2,5-diyl) regioregular (P3HT) and Copper(II) phthalocyanine (CuPc) thin films were used as two different active ...
