Populärvetenskaplig sammanfattning: Sahel kallas regionen som ligger mellan Saharaöknen i norr och den gröna savannen i söder. Det sträcker sig från Atlanten i väst till Röda havet i öst. Området karakteriseras av låg och oregelbunden nederbörd. Torka och svält har drabbat stora delar av området i flera omgångar. Den stora torkan 1984 lever kvar i folks minne som en fruktansvärd katastrof. SatellRecent research has shown significant increasing trends in NOAA NDVI for the Sahel region during the period of 1982-1999. These observations could indicate that the amount of vegetation in the region is increasing. The changes could be interpreted as a recovery from the Sahelian droughts during the 1970´s and 1980´s. However, there are currently large uncertainties as to which processes that have

Abstract in French:Cette recherche s'intéresse à la mobilisation transnationale de la diaspora autour du vote externe et à l'implication des organisations diasporiques dans le processus électoral du pays d'origine. Plusieurs approches expliquent la transnationalisation politique des groupes diasporiques ; cependant, elles ne parviennent pas à clarifier (1) comment certains moments historiques (parThis research is concerned with transnational diaspora mobilisation around external voting and diaspora organisations’ involvement in the homeland electoral process. There are several approaches that explain the political transnationalisation of the diasporic groups; yet, they fail to clarify (1) how some historical moments (e.g., extending the voting right to non-resident nationals) can generate

This paper proposes and explains a type of diagrams which share some of the characteristics distinctive of axial maps, while also differing substantially in some other aspects. A main discussion in Space Syntax is the capacity of different diagrammatic representations to describe relevant morphological characteristics of space: convex maps or visibility graphs at the scale of buildings; axial maps

Environmental change is disrupting mutualisms between organisms worldwide. Reported declines in insect populations and changes in pollinator community compositions in response to land use and other environmental drivers have put the spotlight on the need to conserve pollinators. While this is often motivated by their role in supporting crop yields, the role of pollinators for reproduction and resu

It is important for utilities to plan for Distributed Energy Resources (DER) uptake by representing and modelling their characteristics using appropriate assumptions, methods and tools. Large-scale DER deployment impacts power flows and power system performance in various complex ways as well as potentially contributing to ancillary services. In this paper, we explore state of the art planning me

People living in urban and industrialized societies, which are expanding globally, spend more than 90% of their time in the indoor environment, breathing indoor air (IA). Despite decades of research and advocacy, most countries do not have legislated indoor air quality (IAQ) performance standards for public spaces that address concentration levels of IA pollutants. Few building codes address opera

We live in an era that suffers from climate change issues, not least disaster risks induced by climate change. While measures, such as proper evacuation plans, are required to reduce the negative impacts of disasters when they hit, actions should also be taken to reduce climate change effects by e.g. increasing the use of renewable energies or proper urban land-use allocation, where climate change

The prospect of being able to efficiently inject large plasmids in insulin-producing beta cells is very attractive for diabetes research. However, conventional transfection methods suffer from high cytotoxicity or low transfection efficiency, which negatively affect their outcome. In contrast, nanostraw electroporation is a gentle method that can provide a high transfection efficiency while mainta

The year 2022 marked the 10th anniversary of the course Critical Animal Studies: Animals in Society, Culture and the Media at the Department of Communication and Media at Lund University. As the first initiative of its kind in Sweden, the course explores the shifting roles and positions of non-human animals in today’s complex societies. It aims to equip students with analytical tools to critically

Laminar burning velocities (SL) of di-ethyl ketone (DEK) + air and di-isopropyl ketone (DIPK) + air mixtures were measured using the heat flux method at 305-358 K and equivalence ratios of 0.7–1.4 under atmospheric pressure. Data inconsistency was found between the present SL of di-ethyl ketone + air mixtures and those reported in the literature. Moreover, existing DEK and DIPK combustion kinetic
