Risk Factors For Abandonement Of Wilms Tumor Therapy in Kenya
(University of Nairobi, 2015)Background Survival from Wilms tumor (WT) in sub-Saharan Africa remains dismal as a result of on-therapy mortality and treatment abandonment. Review of patients diagnosed from 2008 to 2011 in our Kenyan Wilms Tumor ... -
Detection And Genetic Characterization Of Porcine Group A Rotaviruses In Asymptomatic Pigs In Smallholder Farms In East Africa: Predominance Of P[8] Genotype Resembling Human Strains.
(University of Nairobi, 2015)Viral enteritis is a serious problem accounting for deaths in neonatal animals and humans worldwide. The absence of surveillance programs and diagnostic laboratory facilities have resulted in a lack of data on rotavirus ... -
Interleukin - 1 Polymorphisms And Chronic Periodontitis In A Rural Kenyan Population
(University of Nairobi, 2015)Susceptibility to Chronic periodontitis (CP) has been associated with genetic polymorphisms in the proinflammatory cytokine, interleukin - 1 (IL - 1A and IL - 1B) isoforms but little is known about their role in rural ... -
Preliminary studies on some local materials for propagation media. 1. Physical and chemical properties.
(Univeristy of Nairobi, 1981)Several materials for raising seedlings in containers before field transplanting were studied, namely coir dust, sawdust, coffee parchments, charcoal dust, local peat moss and sisal waste. Data are presented on their ... -
Effect of plant age on chamomile (Matricaria chamomilla L.) flower yield, essential oil content and composition
(Univeristy of Nairobi, 1989)Seeds of a high-oil-yielding strain of M. chamomilla [Chamomilla recutita] were sown in a nursery and the seedlings were planted in the field 4 weeks after germination. Four rates each of P (0, 40, 80 and 120 kg P2O5/ha) ... -
Effect of nitrogen and variety on essential-oil yield and composition from chamomile flowers.
(Univeristy of Nairobi, 1992)The effects of N (0, 75, 150 or 225 mg/2.7 litre pot) on the essential oil content and composition of the flowers of 2 Matricaria chamomilla [Chamomilla recutita] cultivars were investigated. N (up to 150 mg/pot) significantly ... -
Influence of seedling age and nitrogen application method on dry matter production and nitrogen uptake of lowland rice cultivated on an Alfisol.
(Univeristy of Nairobi, 1992)In a field experiment during the long and short rainy seasons in 1987 at Ibadan, Nigeria, rice cv. IITA 212 DM production was not affected by transplanting 21-, 31- or 41-d-old seedlings. Placement of 60 kg N/ha at 5-10 ... -
Effect of mode and time of nitrogen application on growth and grain yield of lowland rice
(Univeristy of Nairobi, 1992) -
Yield and quality of kale as affected by nitrogen side-dressing, spacing and supplementary irrigation.
(Univeristy of Nairobi, 1984)In trials with the cv. Thousand Headed wide spacing (76 × 60 cm) increased mean fresh weight, branching and leaf production. Close spacing (76 × 30 cm) significantly increased total leaf yield/ha but decreased leaf:petiole ... -
Identification and nutritional importance of indigenous green leaf vegetables in Kenya.
(Univeristy of Nairobi, 1985)Species identified include Amaranthus hybridus [cruentus], Crotalaria brevidens, Solanum nigrum, Gynandropsis gynandra and Erucastrum arabicum. They normally grow wild in most parts of Kenya and the leaves are used as ... -
Contents of nitrate-N and thiocyanate ions in kale (Brassica oleracea var. acephala DC) leaves from kale-growing areas in Kenya.
(Univeristy of Nairobi, 1988)The leaves were sampled in Nov. 1984 and Mar. 1985 from the Kisii, Kericho, Nakuru, Nyahururu, Naivasha, Limuru, Karatina and Kibwezi areas. The results indicated significant differences in nitrate-N contents and thiocyanate ... -
Effect of nitrogen on thiocyanate content of Brassica oleracea var. acephala leaves.
(Univeristy of Nairobi, 1990)In a field experiment in 1985/86 at the Kabele Field Station (alt. 1940 m a.s.l) B. oleracea var. acephala cultivars Thousand Headed (kale) and Georgia (collard) received 0, 47, 94 or 188 kg N/ha. Petiole and, more ... -
The effect of lime levels on the growth of beans and maize and nodulation of beans in three tropical acid soils.
(Univeristy of Nairobi, 1984)The soils used in the greenhouse trial ranged from 4.2 to 5.0 in pH, 1.74 to 4.56 in percentage C, 21 to 32 meq/100 g in CEC, 5.1 to 8.1 meq/100 g in exchange acidity, 0.6 to 3.2 meq/100 g in exchangeable Al and 0.13 to ... -
Buffer pH methods for estimation of lime requirement of tropical acid soils.
(Univeristy of Nairobi, 1981)Lime requirements (LR) of 26 acid agricultural soils were estimated using the following buffer methods: Shoemaker-McLean-Pratt single buffer (SMP-SB), SMP double buffer (SMP-DB), Mehlich buffer method for crops with high ... -
Soil acidity components of tropical acid soils: their roles in determining lime requirement values and the effect of lime upon them.
(Univeristy of Nairobi, 1982)Clay content, pH, organic matter content (%C), cation exchange capacity (CEC), exchangeable Al, exchangeable Mn, exchangeable acidity (ACe), residual acidity (ACr) and total acidity of 26 agricultural soils were determined. ... -
