(University of Eldoret, 2015)Little research work has been done especially on increasing effects of soil acidity on crop production due to long periods of chemical fertilizer use in North Rift region especially Uasin Gishu and Nandi Counties. Moreover, ... -
EFFECTS OF PRICES BEFORE AND AFTER TAX, AND INCOME PER CAPITA ON TOBACCO CONSUMPTION IN KENYA: COINTEGRATION APPROACH
(University of Eldoret, 2021)Smoking of cigarette is regarded as one of the most cause of deaths among other factors in the world. It is also a causative agent of the various cancerous diseases. It is by fact though preventable, the major cause ... -
EFFECTS OF COULOMB AND PAIRING INTERACTIONS BETWEEN NUCLEONS IN DETERMINING NUCLEAR STABILITY OF FINITE NUCLEI
(University of Eldoret, 2021)From time to time, several nuclear models have been proposed by various research groups to explain the properties of finite nuclei and large nuclear systems in nuclear physics and astrophysics. However, no single model ... -
SOLVING MATHEMATICAL WORD PROBLEMS IN SECONDARY SCHOOLS: A CASE OF TINDERET SUB-COUNTY, NANDI COUNTY KENYA
