(2014-04-30)In two experiments carried out in 1970and 1971in the forest zone of Ghana, cuttings of cassava (Manihot esculenta Crantz cv. Ankra), with less than five nodes, produced lower yields per hectare and fewer and lighter tubers ... -
Changes In Genotypes Of Plasmodium Falciparum Human Malaria Parasite Following Withdrawal Of Chloroquine In Tiwi, Kenya
(University of Nairobi, 2012-09)Chloroquine (CQ) drug was withdrawn in 1998 as a first-line treatment of uncomplicated malaria in Kenya. This was in response to resistance to the drug in Plasmodium falciparum malaria parasite. Investigations were conducted ... -
1-Tetralinyl as carboxamine-protecting group for asparagine and application to N-a-t-Butyloxycarbonyl (Boc) solid-phase pentide synthesis of oxytocin
(university of Nairobi, 2014)Oxytocin, a nonapeptide amide, was synthesized on a benzhydryl-resin using the Boc strategy. Benzyl group was used in the protection of sulfhydryl group of cysteine and tyrosine side-chain. Benzhydryl and tetralinyl ... -

Maternal and infant antiretroviral regimens to prevent postnatal HIV-1 transmission: 48-week follow-up of the BAN randomised controlled trial.
(University of Nairobi, 2012-06)BACKGROUND: In resource-limited settings where no safe alternative to breastfeeding exists, WHO recommends that antiretroviral prophylaxis be given to either HIV-infected mothers or infants throughout breastfeeding. We ... -
Prevalence of hepatitis C virus infection among human immunodeficiency virus-1-infected pregnant women in Malawi: the BAN study.
(University of Nairobi, 2012-08)BACKGROUND: In Sub-Saharan Africa, prevalence estimates of hepatitis C virus (HCV) vary widely. OBJECTIVES: To assess the prevalence of HCV infection among HIV-infected, pregnant women screened for a large clinical ... -
Hepatitis B virus infection among HIV-infected pregnant women in Malawi and transmission to infants.
(University of Nairobi, 2014-03)BACKGROUND & AIMS: The extent of HBV infection to infants of HBV/HIV-coinfected pregnant women in sub-Saharan Africa is unknown. The aim of this study was to assess prevalence of HBV infection among antiretroviral-naïve, ... -
Early manual pregnancy diagnosis in dairy cattle in Kenya.
(University of Nairobi,, 1980)Rectal palpations for the purpose of pregnancy diagnosis were performed on 200 dairy cows and heifers at 35, 70 and 150 days of gestation. The cardinal signs used were: membrane slip and amniotic vesicle at 35 days; membrane ... -
A study of blocked teats in small scale dairy farms
(University of Nairobi,, 1992)Fifty five cases of blocked teats from 34 lactating dairy cows are reported. Breed and mammary quarter had no effect but significantly more teats were blocked at the canal than either the base or the tip. The majority of ... -

Homogeneous saturation of the 6328 Å neon laser transition due to collisions in the weak collision model
(University of Nairobi, 1978-08)Measurement of the collision broadened lineshapes of the 6328 Å Ne laser transition in absorbing 20Ne and amplifying 7 : 1 3He : 20Ne discharges indicate that the transition saturates with a Doppler component as well as ... -
Cross Sections For Dephasing Collisions In A Helium-neon Discharge
(University of Nairobi, 1974-11)A single-mode HeNe laser, emitting at 6328 Å, was used to determine the dephasing collision cross sections of Ne 3S2 with ground state Ne and ground state He. We calculate View the MathML source and View the MathML source. -
