The Sahel lies in the semi-arid zone of North Africa between the Sahara Desert to the north and the savannas and rainforest to the south. In the Sahel, the variability of vegetation growth is predominately controlled by moisture reception in the concurrent rainy season. The inter-annual variability of normalized difference vegetation index (NDVI) during the rainy season (April to August) can be ex

The packaging waste problem was realized a couple decades ago. The effectiveness of waste policy instruments and EPR schemes for packaging and packaging waste is still being discussed in Europe. Finland like other EU Member states has transposed EU waste legislation into the national law. An EPR system for packaging and packaging waste in Finland was introduced in 1997. Plenty of changes to this E

ISO 14001:2004 is the most commonly used standard for third-party certification of Environmental Management Systems (EMS) in the world. It is currently undergoing an upgrading process, which will affect all the companies certified to ISO 14001. A first draft has been produced, the Committee Draft 1 (CD1). The thesis has two research questions: What are the most likely changes in the new version

Wine tourism is a niche tourism product that is increasing in wine regions across the world. Wine tourism is also being hailed as a more sustainable approach to tourism due to its promotion of economic, environmental and social sustainability. Sustainable rural development is a high priority around the world due to declining rural economies. Tourism is increasingly being viewed as a component of r

Georgia is facing social and economic challenges and at the same time there are signs that more pressure is put on the environment and natural resources. Georgian industry is energy- intense and encompassing deregulations have put even more stress on the environment. How to combine economic and social goals with environmental concerns has been a hotbed for disputes in Georgia. A recognized approac

The transition towards a sustainable society has become more and more an urban challenge due to a dramatic shift from rural to urban living over the past century. Cities cause environmental and social problems and offer solutions to many sustainability challenges. Living Labs are research infrastructures embedded in a real-life environment, which have recently emerged as a tool for urban governanc

Abstract Host genes for resistance to pathogens and parasites have been a subject of long-term research efforts and continue to be a hot subject in biology. Many important theories have been hypothesized through the years, and they are now being complemented by new and more detailed ones leading to increased understanding of the complex dynamics between host life history strategies and the select

Föreliggande studie undersöker vilken syn på kunskap och lärande vuxna andrapråksinlärare har. Studien bygger på hypotesen att kunskapssynen får konsekvenser för studieresultaten. Perspektivet är det sociokulturella med pedagogiska förtecken. 78 vuxna andraspråksinlärare från 26 olika länder i åldern 19-54 år, som studerade någon av kurserna SVA 1, SVA 2 eller SVA 3 vid komvux höstterminen 2012, s

Syftet med denna uppsats är att undersöka svenska revisorers syn på icke-revisionsmässiga tjänster (IRT) och vilka implikationer detta kan ha på revisorns oberoende och självreglering. Vi har som mål att bidra till debatten om revisorns oberoende, dess koppling till IRT samt även hur det nuvarande förordningsförslaget skulle påverka reglering av IRT i Sverige. Uppsatsen som genomfördes med en kva

The purpose of this study is to examine how well different financial ratios can predict bankruptcy across industries and time. The study also examine whether including industry differences in a prediction model can increase its accuracy. Bankruptcy prediction models were estimated using logistic regression for each year between 2006 and 2011, with and without interaction terms accounting for indu

Multiplatformsutveckling är inte en ny strategi. Men med tanke på hur vanligt förekommande det är för utvecklare att släppa en applikation för endast en platform så kan man konstatera att användningen av multiplatformsutveckling är förvånansvärt liten. I detta examensarbete diskuteras och analyseras aspekter som rör utveckling av en multiplatformsbaserad 3D-applikation. En jämförelse av olika motiCross-platform developing is not a new approach. However, considering it is common for developers to release an application exclusively for a single platform, the use of cross-platform developing is noticeably low. In this master’s thesis, aspects regarding the development of a cross-platform 3D application is examined and discussed. A comparision between different motion capture systems used for

The goal of this master thesis was to examine some of the available development tools for augmented reality in mobile applications. The best development tool were then used in development of an application for Android or iOS. The thesis has two main parts, the analysis of development tools and the application development. During the analysis ve dierent commercial development tools for augmented re

The possibility to print out metallic components with complex 3D-structures is could revolutionize the industry. In this master’s thesis the cause of process parameters have been investigated for three alloys; stainless steel, 316L, two nickel-based alloys, a derivative of Alloy 738 and 939. Microstructure, porosity, tensile testing, impact toughness, hardness and surface roughness was investigate

SYFTE: Vårt övergripande syfte med uppsatsen är att undersöka varför kvinnor är underrepresenterade på partnernivån i revisionsbyråer samt om kön är en begränsningsfaktor. Vi utforskar delägar-, socialiserings- och utvärderingsprocessen och huruvida de bidrar till underrepresentationen. Dessa processer har inte studerats i samma utsträckning som andra personcentrerade variabler, så som kvinnors ba

Water for firefighting is often associated with drinking water, due to fire hydrants. Fire hydrants have been installed in towns for a long time and are one of the most common ways for the rescue service to get hold of water for extinguishing fires. This report evaluates the ways that the rescue service uses their water and how the get continuously water to the fire site. Other extinguishing metho

Thanks to amendments of the regulations governing safety of ships on international voyages, ship-builders are given the possibility to design large merchant ships in novel light-weight materials such as Fibre Reinforced Polymer (FRP) composite. As a part of a collaborative risk assessment, this report investigates the implications of using this new material for the personal risks of firefighting c

The following report contains a study over what happens with the proposals for action that is presented in fire investigations. Literature, 105 fire investigations and interviews were used to gather information. The literature shows that proposals for action are a natural conclusion in almost all investigation methods but little over half of the fire investigations present them and only a few had

A safety feature for the evacuation of a rail tunnel is the construction of walkways running parallel to the tracks, constructed at the level of the train’s exits. There is currently a lack of research-based information pertaining to how the width of the walkway may affect evacuation. In September 2012 an evacuation experiment was performed, the aim of which was to explore how the width of the wal
