Morphology of the Left Atrial Appendage: Prevalence and Gender Difference in a Kenyan Population
(University of Nairobi, 2018)ntroduction The left atrial appendage is the site of origin of thrombi in 90% of cardioembolic stroke. Although literature reports a higher risk of cardioembolic stroke among blacks and females, it is unclear whether ... -
Sex differences in histomorphology of the human carotid body
(University of Nairobi, 2017-06)Knowledge of sex differences in the histomorphology of the carotid body is important in understanding observed differences in respiratory function and disorders. There are few studies on sex differences in the carotid body. ... -
The relation of the extracranial spinal accessory nerve to the sternocleidomastoid muscle and the internal jugular vein. Cranial Maxillofac Trauma Reconstruction
(University of Nairobi, 2019)The spinal accessory nerve (SAN) exhibits variant anatomy in its relation to the internal jugular vein (IJV) as well as the sternocleidomastoid muscle (SCM). These variations are important in locating the nerve during ... -
Effects of Substrate Radial-Position Relative to the Sputter-Gun Axis on the Electrical, Optical and Structural Properties of ZnO Thin Films Deposited by Reactive Direct Current Magnetron Sputtering
(University of Nairobi, 2018)ZnO thin films were deposited using reactive direct current (dc) magnetron sputtering on glass substrates placed at seven variable radial positions (-1, 0, 1, 2, 3, 4 and 5 cm) relative to the sputter-gun (target) axis. ... -
Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
(University of Nairobi, 2018)Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising semiconductor for phase change memory devices due to its thermal stability and low power consumption. The study investigated the effect of ... -
