(Springer, 2018)Iron-modifed raw kaolinite clay (Fe-MC) was synthesized by co-precipitation method, characterized, and then applied as a low-cost adsorbent to sequester sulfachloropyridazine (SCP) and sulfadimethoxine (SDM), emergent ... -
Single and competitive removal of sulfachloropyridazine and sulfadimethoxine onto natural kaolinite clay: kinetics, isotherms and thermodynamics studies
(2017)In this study, local untreated clay was tested for its ability to adsorb sulfonamides, namely, sulfachloropyridazine (SCP) and sulfadimethoxine (SDM) from synthetic wastewater by batch equilibration. The time-dependent ... -
Single dose versus extended dose antibiotics in prevention of surgical site infection in elective caesarean section at a tertiary hospital in Kisumu-Kenya: a randomized controlled trial
(Maseno University, 2023)When compared to other surgical procedures overall, Caesarean section (CS) accounts for the most recorded cases of surgical site infection (SSI). Following CS, antibiotic prophylaxis usage has been proven to lower incidence ... -
The single most influential school-based factor affecting student achievement is teacher quality. Teacher quality is a function of, among other variables, the training programme, teacher experience and the competence of the teacher educator. The quality of pre-service training to prospective teachers in teacher training institutions goes a long way to influence their performance in the field. This research paper examines the role of academic qualifications of college tutors, areas of specialty i.e. their major and minor teaching subjects at the college/university level , and the assigned subject area. The paper also evaluates the effectiveness of the Teachers Service Commission deployment policy. This is a case study of Mosoriot Teachers Training College, in Nandi County, Kenya. Data was collected by use of questionnaires, face-to-face interviews and staff establishment records. Of the total teaching force of 71, 65 (91.5 %) tutors participated in this study. The data was descriptively analysed using percentages. The findings reveal that a) there is great disparity between teacher recruitment and deployment policy and practice where the college tutors were not teaching subjects for which they were not deployed to teach, and b) there was out-offield teaching in teacher education institutions. The researcher recommends that the Teachers Service Commission re-examine the staffing norms in Teachers Training Colleges with a view to maximize the human resource and enhance quality of training
