Effects of sample drying temperature on indices of available nitrogen in soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: G.H. Wiltshire --- Department of Soil Science, Republic of South Africa C.C. du Preez --- Department of Soil Science, Republic of South AfricaDuring a field trial investigation into the long-term effects of conservation practices on the nitrogen fertility of a soil cropped annually to wheat, it was observed that sample preparation had an effect on some indices of available nitrogen. The trial... -
The effect of oven-drying on residual inorganic nitrogen in soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: G.H. Wiltshire --- Department of Soil Science, Republic of South Africa C.C. du Preez --- Department of Soil Science, Republic of South AfricaResidual ammonium nitrogen in soils which were dried in an oven increased, whereas residual nitrate nitrogen remained almost constant. This observation led to experiments which help to explain the accumulation of ammonium nitrogen in oven-dried soils. It was found that... -
A Survey of the Views of College Students on Academic Dishonesty
Item type: Journal Article • Journal: Journal of Psychology in Africa • Authors: Joseph M. Kasayira --- Midlands State University, Zimbabwe Starlin Musingarabwi --- Mkoba Teachers College, Zimbabwe Solomon Nyanhongo --- Midlands State University, Zimbabwe Kudzai S. Chipandambira --- Midlands State University, Zimbabwe Tholene Sodi --- University of Venda, South AfricaThe purpose of the study was to examine students' views on dishonest academic behaviours. First year students from Mkoba Teachers' College in Zimbabwe's city of Gweru (n = 152) responded to an open-ended questionnaire that was used to collect data... -
Performance and design optimisation of an apparatus for distilling palm wine (Elaeis guineensis) by controlling thermal operations
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Clément Ahouannou --- Laboratory of Applied Mechanics and Energy, Polytechnic School of Abomey-Calavi, Benin Fidèle Tchobo --- Laboratory Study and Research in Applied Chemistry, Polytechnic School of Abomey-Calavi, Benin Emile A. Sanya --- Laboratory of Applied Mechanics and Energy, Polytechnic School of Abomey-Calavi, Benin Christa Lokossou --- Laboratory Study and Research in Applied Chemistry, Polytechnic School of Abomey-Calavi, Benin Mohamed Soumanou --- Laboratory Study and Research in Applied Chemistry, Polytechnic School of Abomey-Calavi, BeninMastery of thermal control in the craft distillation processing operations of fermented wine from Elaeis guineensis is needed to improve and enhance the resulting Beninese alcoholic drink, sodabi. In this study, craft distillation of palm-wines from three municipalities of southern... -
Effects of fragmented mangroves on macrozoobenthos: a case study of mangrove clearance for powerline right-of-way at Oproama Creek, Niger Delta, Nigeria
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: N Zabbey --- , Nigeria IG Ekpenyong --- , Nigeria GN Nwipie --- , Nigeria IC Davies --- , Nigeria K Sam --- , NigeriaMangroves are vulnerable to varying magnitudes of degrading impact by human activities. Despite the many benefits of mangrove ecosystems, mangroves in the Niger Delta region are often cleared for electric powerline and oil pipeline rights-of-way, recreation, road construction, housing and... -
Rod temperature regulation using current and time-delayed feedback
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: V.M. Abdullayev --- Institute of Control Systems of ANAS, Azerbaijan K.R. Aida-Zade --- Institute of Control Systems of ANAS, AzerbaijanThe synthesis problem of control of objects with distributed parameters with feedback is investigated on the example of the process of heating a rod in a furnace. To generate the values of control actions, we propose to use their linear... -
The future of higher education in the age of GenAI — are we all doomed?
Item type: Journal Article • Journal: Research in Hospitality Management • Authors: Erwin Losekoot --- School of Business & Law, Edith Cowan University, AustraliaThis viewpoint addresses the concern expressed by some academics that GenAI is turning the works of higher education upside down and that our roles as educators will soon become redundant. It considers the academic literature on student academic misconduct and...
