Binding energies of excitons in symmetric and asymmetric coupled double-quantum well structures in a magnetic field
(1999)
The binding energy of excitons in the symmetric and asymmetric coupled double GaAs/$Ga_{1-x}Al_xAs$ quantum wells is calculated by using variational approach. Results have been obtained as a function of the potential ...
The determination of some heavy metal cations by TLC/ photodensitometry
(1996)
The samples having complex matrices were analyzed for some heavy metal cations by using a thin layer chromatography/photodensitometry (TLC/PD) system. The rock samples were dissolved by suitable methods. Nickel, Cobalt and ...
A Comparison of germ tube production by candida albicans in three madia
(1998)
C. albicans' ın komersal durumdan pathojenik duruma dönüsümü, maya formundan hif (jerm tüp) formuna dimorfik geçisi yapılabilmesiyle ilgilidir. Üç sıvı ortamda Candida albicans 'ın germ tüp olusumu uyarabilmesi için ...
Application of the correspondence-type geostatistical analysis on the Co, Ni, As, Ag and Au concentrations of the listwaenites from serpentinites in the Divriği and Kuluncak ophiolitic melanges
(1998)
Bu çalışma Divriği ve Hekimhan bölgelerindeki üç farklı listvenit mostrasından alınan örneklerin Co, Ni, As, Ag ve Au konsantrasyonları arasındaki olası ilişkiyi bulmayı amaçlamıştır. Cürek-Divriği, Sivas , Güvenç ve ...
Renal ultrastructural Alterations following administration of diethyistilbestrol
(1998)
Diethylstilbestrol (DES), nons-teroid in structure, is an artificial estrogen derivative and is used as an anabolic agent. It is known that diethylstilbestrol causes genet-ic disorders and toxic effects leading up to ...
The construction of a mammalian tranfection vector for expression of cytosine-5 specific DNA methyltransferase gene M.Msp1 in cultured cells
(1998)
Ekspresyon vektörleri normal yada rekombine bir genin istenilen hücreye aktarılması, ekspresyonu ve proteinin saflastırılmasına olanak saglayacak sekilde olusturulurlar. Günümüzde mem hücrelerin transient yada stabil gen ...
Burial and thrust-related very low-grade metamorphism in the Upper Paleozoic meta-sedimentary rocks at the Kangal-Alacahan area,Sivas Turkey
(1997)
Kangal-Alacahan yöresindeki Orta Devoniyen-Alt Karbonifer yaşlı Kangal formasyonu meta-klastitleri alttan üste doğru sedimanter gömülme ve bindirme sonucu gelişen farklı litolojik, dokusal ve mineralojik özelliklere sahiptir. ...
Orthogonal symmetric bi-derivation on semi-prime gamma rings
(1997)
[2] de Bresar ve Vukman ortogonal türevler çalıştılar. [4] de Soytürk, [2] deki bazı çalışmaları T-halkasında ispatladı. Bu çalışmada; [2] ve [4] deki türev yerine simetrik bi-türev'in izini alarak bazı sonuçlar elde ettik.
Trigeminal nerve and brainstem catecholamine systems in cerebral vasospasm
(JAPAN NEUROSURGICAL SOC, 1998)
Cisternal blood injection in the rat and squirrel monkey produces a biphasic cerebral vasospasm, a decrease in cerebral blood flow (CBF) and an increase in glucose uptake (CMRglu) due to an anaerobic glucolysis actually ...
Catalytic-oxidative destruction of benzo-b-thiophene by Fenton' s reagent
(1999)
In order to determine the oxidation behaviour of benzo-b-thiophene, destructive oxidation using Fenton's reagent was studied. Benzo-b-thiophene was converted to benzo-b-thiophene-S,S-dioxide but oxidation resulted mainly ...
