Draught requirements of enamel coated animal drawn mouldboard plough
(Czech Academy of Agricultural Sciences http://agriculturejournals.cz/web/RAE.htm, 2005)
The power requirement of tillage implements is an important design consideration particularly for animal-drawn implements where the power is limited. The paper presents the possibility of reduction in the draught requirements ...
Analysis of gender differences in education for engineering career (Gaborone case study)
(University of Botswana, 2000)
The percentage of students, especially women in engineering, is very low in Botswana and the country is still heavily dependent upon foreign human resources. The objective of this research has been to study the gender ...
An investigation into the possibility of establishing a building index for Botswana
(University of Botswana, 2001)
Without cost information, project planning is difficult for clients just as pricing of tenders is difficult for construction firms. No agency or organization in Botswana has endeavoured to collect, compile and analyze ...
Environmental impacts of fly ash
(University of Botswana, 2000)
Alarmingly high accumulation of fly ash has led geochemical engineers into finding a solution for the use of flyash as a construction material in the recent past. As of now, although the material has been used in a limited ...
The role of trustworthiness in the formation and governance of construction alliances
(Elsevier Ltd; www.elsevier.com/locate/buildenv, 2006-05-04)
The ensuing globalization of the construction industry as well as the highly fragmented and divisive nature of the industry are among the forces that are influencing it to seek management approaches such as strategic ...
Self-clocked sequential circuits: a design example
(University of Botswana, 2004)
Asynchronous sequential circuits offer improved speed of operation when compared to their synchronous counterparts. However, the standard methods of asynchronous design require careful examination of the flow table for ...
Theoritical analysis of an offset single-stroke ram press for sunflower oil extraction
(International Symposium on Theory of Machines and Mechanisms (IFToMM), 2001)
The single-stroke ram press machine is widely used for sunflower oil extraction in African countries. It is manually operated, low speed machine constructed on the basis of slider-crank mechanism. The paper presents a ...
Implementation of a single phasing protective circuit for three phase induction motors
(University of Botswana, 2006)
Analysis of the induction motor failures show, that a significant number of motors are damaged due to single phasing.At such conditions the current increases rapidly and the motor is subjected to burnouts and consequently ...
Reservoir storage requirements in arid areas
(University of Botswana, 2006)
Water reservoir storage requirements are a function of demand and variation in inflow. The greater the variation the greater the storage required to meet a specified draft. The selected recurrence interval of failure also ...
Design of automatic power factor control system
(University of Botswana, www.ub.bw, 2004)
Maintenance of the proper power factor is a very important matter for the industry and for the economy of any country. A study of the power factor value for a number of industrial plants in Botswana shows that they operate ...
