Recalibrating prognostic models to improve predictions of in-hospital child mortality in resource-limited settings
(University of Nairobi, 2023)Background: In an external validation study, model recalibration is suggested once there is evidence of poor model calibration but with acceptable discriminatory abilities. We identified four models, namely RISC-Malawi ... -
Recent changes in the fishery of a new tropical man‐made lake, Lake Kamburu (Kenya)
(University of Nairobi, 2006-01)Five years after inundation, two varieties of Cyprinus carpio—the common carp and the mirror carp, have appeared in the commercial fishery in Lake Kamburu. Species of Tilapia continue to remain the most abundant fish in ... -

Recent geophysical studies of the kenya rift valley
(1977)This paper describes some of the recent geophysical work done in Kenya with a view to determining the structure of the crust and upper mantle in the vicinity of the Rift Valley. The principal techniques used are described ... -
Recent Progress and Challenges in Combating the HIV/AIDS Epidemic: A Review
(University of Nairobi, 2014-01)The human immunodeficiency virus (HIV), the virus that causes the acquired immune deficiency syndrome (AIDS) has for many years devastated lives and still continues to do so in the present day. Reducing the spread of ... -
The recent secular variation of declination and inclination in Kenya
(University of Nairobi, 1975)Oriented specimens of very young lavas have been collected from 3 volcanic sites in Kenya in order to determine the declination and inclination angles at the times the lavas cooled. TheseD andI values have been tentatively ... -
Recent Trends of Minimum and Maximum Surface Temperatures over Eastern Africa
(Department of Meteorology, University of Nairobi, 2000-08)This study investigated recent trends in the mean surface minimum and maximum air temperatures over eastern Africa by use of both graphical and statistical techniques. Daily records for 71 stations for the period \939-92 were ... -
Reciprocal allogrooming in impala, Aepyceros melampus
(University of Nairobi, 1992-12)Adult female and male impala engage in a type of allogrooming in which partners alternately deliver bouts of oral grooming to the head and neck. These grooming encounters comprise typically six to 12 tit-for-tat-like ... -
Recombinant Rhipicephalus appendiculatus gut (Ra86) and salivary gland cement (Trp64) proteins as candidate antigens for inclusion in tick vaccines: protective effects of Ra86 on infestation with adult R. appendiculatus
(School of Biological Sciences, 2011)Rhipicephalus appendiculatus gut protein Ra86 (variants Ra85A and Ra92A) and the salivary gland cement protein (Trp64) were expressed in the baculovirus-insect cell system. The recombinant gut proteins expressed as soluble ... -
Records from the dry lands of Kenya, with a description of Didymodon revolutus var. nov. africanus (Pottiaceae).
(2007)Pneumatocele, a special form of lung injury, is characterized by intrathoracic images of cavities detected on X-ray films. These cavities develop immediately after a trauma of the thorax, disappear rapidly and have a ... -
