(1997)
Bu çalışmada, bazı Vicia L. türlerinin ve V. sativa L.'nın bazı ıslah hatlarının çekirdek DNA içerikleri, çekirdek alanları ve kromozom sayıları araştırılmıştır. Vicia türlerinin DNA içeriğinde önemli bir varyasyon ...
Electric field dependence of the excitonic properties in graded double quantum wells
(IOP PUBLISHING LTD, 1999)
A quasi-bound state approximation is used to obtain the electric field dependence of the eigenvalues, eigenfunctions, electron-hole overlap integrals and excitonic binding energies for coupled, graded double quantum wells ...

Second law analysis of the reheat-regenerative rankine cycle
(PERGAMON-ELSEVIER SCIENCE LTD, 1997)
Energy and exergy analyses were performed for each component in the system and the results tabulated. The variations of availability difference, irreversibility and efficiency with several parameters were graphically ...
Dodurga (Çorum) kömür havzasında karbonat ve smektit minerallerinin kökeni ve diyajenetik evrimi
(1998)
Dodurga formasyonunun ana litolojisini kiltaşı, bitümlü şeyi, dolomit ve kömürler oluşturmaktadır. Kireçtaşı ve marnlar ise arakatkılar biçiminde ender olarak gözlenmektedir. Egemen mineralleri killer, yer yer de kalsit ...
Shear flocculation of chromite fines in sodium oleate solutions
(ELSEVIER SCIENCE BV, 1996)
In this study, chromite fines were aggregated by stirring after the particle surfaces were made hydrophobic with sodium oleate. The effects of pH, sodium oleate concentration, stirrer speed and flocculation time were ...
Strategies for reducing solvent toxicity in extractive ethanol fermentation
(HUMANA PRESS INC, 1998)
Extractive fermentation is a widely preferred technique in which the products of fermentation are removed from the fermentation medium by a proper solvent, in order to avoid the inhibitory effects of the products. In this ...
Behaviors of acrylamide/maleic acid hydrogels in uptake of some cationic dyes from aqueous solutions
(MARCEL DEKKER INC, 1996)
Acrylamide/maleic acid (AAm/MA) hydrogels prepared by irradiating with gamma-radiation were used in experiments on swelling, diffusion, and uptake of some cationic dyes such as basic red 9 (BR-9), basic green 4 (BG-4), ...
Effect of deferoxamine and sympathectomy on vasospasm following subarachnoid hemorrhage
(KARGER, 1996)
We examined the effects of subarachnoid hemorrhage (SAH) and treatment with deferoxamine (DFO) or sympathectomy on vascular smooth muscle function, as well as the underlying mechanisms involved, by recording the responses ...
Effects of sympathectomy on endothelin-1 and histamine responses of rabbit carotid artery
(ELSEVIER SCIENCE INC, 1997)
1. The effects of chronic sympathectomy on contractile responses of rabbit common carotid artery was studied in vitro. 2. Endothelin-1 (ET-I), histamine, KCl and papaverine concentration-response curves of sympathectomized ...
