The paper deals with various initiatives undertaken, or to be undertaken, by Government of Botswana, and which may be looked upon as "Information Society" initiatives. These initiatives are critically analysed and conclusions are drawn from the authors' analysis. Based on conclusions, the authors make certain recommendations regarding implementation of the initiatives.
Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha
In modern industrialised society prepared meals and eating out of home is an increasing phenomenon. This develops new business opportunities for food manufacturers, since they need to create more convenience to the consumers through food that can be prepared and served quickly. However, the new food products require increased quality and safety and thereby more controlled distribution. The issue i
Scholarship of Teaching and Learning (SoTL) is discussed as a strategy for institutional improvement of teaching and learning. Engagement in SoTL could be an individual enterprise focusing external networks including conference presentations and journal publications. This strategy could lead to development and improved teaching for the individual but not necessarily contribute to the developme
In TSP with neighborhoods (TSPN) we are given a collec-tion X of k polygonal regions, called neighborhoods, with totally n ver-tices, and we seek the shortest tour that visits each neighborhood. TheEuclidean TSP is a special case of the TSPN problem, so TSPN is alsoNP-hard. In this paper we present a simple and fast algorithm that, givena start point, computes a TSPN tour of length O(log k) times
Planning and implementing an open-loop, business-wide national pool system for transport packaging (trays and pallets) is a complex process. This research project is focusing on the driving forces in the development and decision processes. During 1992-1999, a group of logistics specialists within the Swedish food supply chains took part in a development process, which included much learning and ne
Popular Abstract in Swedish Katalys är en nyckelteknik inom kemisk industri och spelar en förvånansvärt viktig roll i vårt moderna samhälle. Många av de produkter och kemikalier som används i vårt dagliga liv produceras faktiskt med hjälp av katalysatorer. En annan mycket viktig tillämpning är att avlägsna giftiga ämnen från fordonsavgaser. Det mest fantastiska är att en katalysator snabbar på ochThis PhD thesis reports on investigations of the atomic scale structure of model catalysts relevant for the catalytic oxidation of CO and methane over Pd, and NOx reduction over silver-alumina, important reactions in automotive catalysts. By using complementary experimental techniques such as X-ray Photoelectron Spectroscopy, High Pressure X-ray Photoelectron Spectroscopy, Surface X-ray Diffractio
In communication systems, all service control nodes, such as for example Web sites or mobile switching centers, can be modeled as a server system with one or more servers processing the incoming requests. To avoid overload at the service node some type of admission control mechanism is usually implemented to guarantee good performance also during high traffic loads. In this paper we investigate, f
Popular Abstract in Swedish Vibrationsskador i händerna utgör idag ett stort yrkesmedicinskt problem. Långvarig exponering av handhållna vibrerande verktyg kan leda till ett hand-arm vibrationssyndrom (HAVS) som är en kronisk åkomma. Vibrationsskadan kan vara irreversibel och är progressiv om vibrationsexponeringen fortsätter. Många arbetare utsätts dagligen för hand-arm vibrationer. Elva procent Workers exposed to hand-held vibrating machines may risk developing a hand-arm vibration syndrome (HAVS), a condition which can cause chronic impairment and disability. The aims of this thesis were 1) to obtain deeper insight and further knowledge of HAVS and the consequences for hand function, and aspects of quality of life (QoL); 2) to investigate the usefulness of clinical assessments in diagno
Background: GEOMAGIA50.v3 for sediments is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data obtained from lake and marine sediments deposited over the past 50 ka. Its objective is to catalogue data that will improve our understanding of changes in the geomagnetic field, physical environments, and climate. Findings: GEOMAGIA50.v3 for
Many migratory birds have changed their timing of arrival at breeding grounds in response to recent climate change. Understanding the adaptive value and the demographic consequences of these shifts are key challenges. To address these questions we extend previous models of phenological adaptation to climate change under territory competition to include feedback from population dynamics, winter sur
