Summing up - Batch 21: Change Projects from the International Training Programme : Child Rights, Classroom and School Management - Batch 21

Lund University has offered the Sida-financed International Training Programmeon Child Rights, Classroom and School Management since 2003.The programme targets those in a position from which they can initiate processesof change in the education sector in their countries. During the programmeall participating teams initiate a change project in their respectivecountries aiming at the realization of

Sustainable development through innovation diffusion via an entrepreneur in rural western Kenya : Progress and related challenges

This article presents the accomplishments and challenges of a rural sustainable development initiative in Nyanza Province, Kenya. Our focus is on the sale and financing of a simple technology — an improved cookstove — by a local entrepreneur. The theoretical basis of the research is innovation systems and (social) entrepreneurship. We first de­fine the major challenges of the diffusion process enc

The color of child survival in Colombia, 1955-2005

Objective(s): Colombia has the third largest black population in the Americas after Brazil and the USA. In 2005 mortality rate under 5 in Colombia was 21.5 per 1000, with a reduction of 82 per cent between 2005 and 1960. That rate is not in line with rates for Cuba (6.8), Chile (9.1) or Costa Rica (10.4). Here we aim to provide evidence that a further reduction of child mortality relates to the un

Cascades of green: A review of ecosystem-based adaptation in urban areas

Climate change impacts increase pressure on challenges to sustainability and the developmental needs of cities. Conventional, “hard” adaptation measures are often associated with high costs, inflexibility and conflicting interests related to the dense urban fabric, and ecosystem-based adaptation (EbA) has emerged as a potentially cost-efficient, comprehensive, and multifunctional approach. This pa

Perceptions of the ecosystem services concept: Opportunities and challenges in the Swedish municipal context

A current focus of ecosystem services (ES) implementation is on the municipal level of government where international and national legislation and policies have to be translated into practice. Given this focus, an understanding of perceptions within municipalities of the ES concept is crucial to support the implementation process. Against this background, this paper examines the perceptions of Swe

Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. At high load the exhaust heat was increased more than at high engine speed. Swir

Iron Carbonyl Clusters as Proton Reduction Catalysts

En utveckling av den s. k. väte-ekonomin, där vätgas (H2) används som energibärare, skulle – rent teoretiskt – kunna lösa människans energiproblem då vatten skulle kunna användas som bränsle. För att nå detta mål krävs dock väsentlig teknologisk och vetenskaplig utveckling. Ur ett rent vetenskapligt perspektiv, måste bl a (energisnåla) kemiska metoder att skapa stora mängder vätgas utvecklas. MångAbstract – The mixed-valence triiron complexes [Fe3(CO)7-x(PPh3)x(µ-edt)2] (x = 0, 1, 2; edt = SCH2CH2S) and [Fe3(CO)5(κ2-diphosphine)(µ-edt)2] (diphosphine = dppv, dppe, dppb, dppn) have been prepared and structurally characterized. In comparison to the diiron complex [Fe2(CO)6(µ-edt)], [Fe3(CO)7(µ-edt)2] catalyzes proton reduction at 0.36 V less negative potentials, which is a significant energe
