Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
The Effects of Combination of Verapamil and MK-801 on Rat Neuropathic Pain Model
(2003)
N-methly-D-aspartae receptor is activated by calcium. The effects of a calcium antagonist verapamil and N-methly-D-aspartae receptor antagonist MK-801 on thermal nociception in rat model of chronic nerve injury was well ...
Serum leptin levels and their relationship to tumor necrosis factor-? and interleukin-6 in neonatal sepsis
(2003)
Circulating leptin concentrations are raised in animal models of inflammation and sepsis and leptin production is also increased in rodents by administration of endotoxin or cytokines. The purpose of this study was to ...
Isolation of DNA for RAPD analysis from dry leaf material of some Hesperis L. specimens
(2003)
An improved protocol for the isolation of DNA from dry material of some Hesperis specimens is described. The isolated DNA is suitable for random amplification of polymorphic DNA (RAPD) analysis. Different DNA extraction ...
Primary repair of a sternal cleft in an infant with autogenous tissues
(2003)
A cleft sternum is a rare congenital anomaly often diagnosed as asymptomatic at birth. Clinical outcome may be unfavorable when an associated anomaly, particularly an intracardiac anomaly coexists with the defect. Primary ...
The bats of the eastern Black Sea region in Turkey (Mammalia: Chiroptera)
(2003)
The study was carried out on 89 specimens representing 11 bat species, Rhinolophus ferrumequinum, R. hipposideros, R. euryale, Myotis brandtii, M. bechsteinii, M. myotis. Pipistrellus pipistrellus, P. kuhlii, Nyctalus ...

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 ...
