Comparative implementation studies of the minimal controller synthesis algorithm on an electrohydraulic actuator plant
(2007)
Electrohydraulic servosystems have large extent of model uncertainties and generally difficult to control. The current paper studies the application of the direct adaptive minimal controller synthesis (MCS) algorithm to ...
Single mode optical radiation distribution and reflectivity calculations in novel-hot electron light emission and lasing in semiconductor heterostructures VCSELs
(2004)
In this work, we calculate the power reflectivity in vertical cavity surface emitting lasers (VCSELs) using a new method. In VCSELs, the stop band of the reflectivity spectrum should exhibit a dip at the lasing wavelength, ...
The effect of montelukast on eosinophil apoptosis: Induced sputum findings of patients with mild persistent asthma
(Ediciones Doyma, S.L., 2005)
Background: Apoptosis may be important in limiting airway eosinophilia. Treatment with leukotriene antagonists decreases the number of eosinophils in both peripheral blood and sputum. Aim: To assess the effect of montelukast ...
Screening of antioxidative properties and total phenolic compounds of various extracts of three different seed of grape varieties (Vitis vinifera L.) from Turkish flora
(Asian Network for Scientific Information, 2007)
This study was designed to examine the in vitro antioxidant activities and total phenolic contents of various extracts prepared by using solvents of varying polarity from three different seed of grape varieties (Vitis ...
Cystinuria: Cause of renal stones in a one-year-old girl [Bir yaşindaki bir çocukta böbrekte taş nedeni olarak sistinüri]
(2005)
Cytinuria is an inherited disorder of cystine and dibasic amino acids involving renal and intestinal transport mechanisms. The only clinical manifestation of this disease is the development of urinary tract cystine stones. ...
Closure or nonclosure of the peritoneum at gynecological operations. Effect on postoperative pain
(2005)
Objective: To compare the analgesic requirement and pain scores in the postoperative period between closure and nonclosure of the peritoneum in women undergoing gynecological abdominal surgery. Methods: We conducted this ...
Evaluation of the marginal gingival health using laser Doppler flowmetry
(2006)
The purposes of this study were to compare the gingival blood flow (GBF) in test sites (teeth retaining fixed partial dentures) and control sites (contralateral natural teeth) and investigate whether there is any relationship ...
Non-linear dynamics in a graded quantum well placed in a GaAlAs p-n junction
(2001)
Theoretical and experimental results concerning the study of a novel wavelength converter amplifier, which can be tuned, with the amplification of an external voltage are presented. The device consists of a Ga1-xAlx As ...
Epidermoid cyst in a girl: Constructive interference in steady-state and diffusion-weighted imaging findings
(2006)
Intracranial epidermoid cysts can closely mimic cerebrospinal fluid on magnetic resonance imaging and computed tomography. Epidermoid cysts are isointense to slightly hyperintense relative to cerebrospinal fluid on T1-, ...
Removal of ammonium from municipal wastewater using natural Turkish (Dogantepe) zeolite
(2005)
This paper concerns the removal of ammonium ions from wastewater using a naturally occurring zeolite from Dogantepe region in Turkey. Both batch and continuous (column) experiments were carried out. In batch studies, effects ...
