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 ...
Temperature control of a batch polymerization reactor
(INST CHEMICAL ENGINEERS, 1999)
In this work, DMC (Dynamic Matrix Control) of a batch solution polymerization reactor has been investigated experimentally and by simulation to achieve a specific constant number average chain length and conversion in a ...
Geochemical characteristics of Yamadagi volcanics in central east Anatolia: an example from collision-zone volcanism
(ELSEVIER SCIENCE BV, 1998)
Neogene Yamadagi volcanic rocks consist of basaltic trachyandesite, trachyandesite, andesite, and dacite. The major- and trace-element chemistry indicates that the lavas are dominantly calc-alkaline and mildly alkaline in ...

Binding energies of excitons in symmetric and asymmetric quantum wells in a magnetic field
(ACADEMIC PRESS LTD, 1998)
The binding energy of the exciton in the symmetric and asymmetric GaAs/Ga1-xAlxAs quantum wells is calculated with the use of a variational approach. Results have been obtained as a function of the potential symmetry, and ...
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.

Changes in the nitric oxide system of rat myometrium during midgestation and delivery at term
(ACADEMIC PRESS LTD, 1998)
The aims of this study were to investigate whether a nitric oxide (NO) system is present in the pregnant rat myometrium and whether it differentially inhibits myometrial contractility during midgestation and delivery at ...
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 ...
