Experimental and theoretical investigations of mouldability for feedstocks used in powder injection moulding
(2007)
Experimental and theoretical analyses of mouldability for feedstocks used in powder injection moulding are performed. This study covers two main analyses. (i) The experimental analysis: the barrel temperature, injection ...
Effects of Behcet's disease on hearing thresholds and transient evoked otoacoustic emissions
(2007)
Objectives: The aim of this prospective study was to investigate hearing loss in patients with Behçet disease (BD). Methods: The study group consisted of 20 patients (8 males, 12 females) with BD and 40 ears. The control ...
Distribution of Candida species in women with vulvovaginal symptoms and their association with different ages and contraceptive methods
(2007)
The aim of this study was to determine the frequency and distribution of Candida spp. within different age groups and different contraceptive methods users in women with vulvovaginal symptoms. The study included 569 female ...
Choroid epithelial cells: Source cerebrospinal fluid progesterone in sheep?
(2007)
The present study was conducted to immunolocalize 3?-hydroxysteroid dehydrogenase (3?-HSD), an enzyme metabolizing pregnenolone to progesterone in the choroid plexus of the lateral ventricle in sheep, as well as to measure ...
The effect of Ag electromigration on the properties of BiPbSrCaCuO superconductors
(Elsevier, 1997)
The effect of an electric field on the diffusion of silver and compounds (Cu and Sr) of BiPbSrCaCuO ceramic superconductors was investigated by energy-dispersive X-ray spectroscopy (EDX). It was established that Ag migrates ...
Viscosity molecular weight determination of polyadenylic acid
(1995)
In this study viscosity measurements of polyadenylic acid (PolyA) in aqueous solution were carried out under different conditions. In the absence of any additives, the polymer degraded during flow through the capillary of ...
Herbicide penetration through isolated periderm and cuticular membranes
(1996)
The penetration of three herbicides through isolated potato periderm (PM) and pear fruit cuticular membranes (PFCM) as their commercial formulations was examined in two separate experimental methods involving infinite and ...
Determination of rolling element bearing defects through vibration analysis
(2003)
Determination of rolling element bearing defects through the available vibration analysis method is studied in this paper. Rolling element bearing defect vibrations, vibration measurement and their analysis is briefly ...
A full adaptive observer for DC servo motors
(2003)
An adaptive observer estimating all parameters and load torque is proposed for DC servo motors. The observer uses no direct feedback but the adaptation schemes use current and speed measurements. Both the observer and ...
Determination of physical faults in gearbox through vibration analysis
(2003)
Gears are important machine elements that provide motion or power transmission. Accuracy and quality of work done is directly related to the continuous motion transmission in a machine. Therefore, the determination of ...
