In recent years the railway has received a lot of negative publicity thanks to the large amount of delay hours that occurs during winter conditions and especially at snowfall. In our railway network, the points are the most targeted problem components were snow and ice cause the most problems. Due to its moving parts and low tolerances for disorder, a few millimeters of gap between the rails is en

Populärvetenskaplig sammanfattning Översvämningar är i dagsläget ett allvarligt problem och med den kommande klimatförändringen så kommer frekvensen av översvämningar att öka. EU har tagit fram ett översvämningsdirektiv som innebär att alla medlemsländer ska analysera översvämningsrisker och framställa planer med åtgärder. Enligt tidsplanen i direktivet ska analyser och planer vara klara senast 20Flooding is a serious problem and with the upcoming climate change, the frequency of flooding will increase. The EU has produced a flood directive requiring all the member countries to analyze flood risks and prepare plans of actions. According to the timetable of the Directive, analyzes and plans are required to be ready by 2015. In the southwestern part of Scania lies the catchment of Segeån. He

'Silence' in one word grasps the gendered structures within the Danish daycare regime. Through a rearticulation of this notion a detailed inquiry of processes with gendered effects within the public administration of the daycare regime is carried out. Though public daycare is an universal welfare service with political attention where gender-issues are very present, and a general gender-ma

Populärvetenskaplig sammanfattning Gallring är en viktig del i det moderna skogsbruket. I Sverige har gallring skett i ca 150 år och i början av 1900-talet ökade intresset då pappersmassaindustrin tog fart. Detta ledde till ett ökat intresse för mindre träd och successivt så ökade behovet att utveckla strategier och gallringsmetodiker. I Sverige genomförs gallringar med 10-25 års intervall och manThe aim of this study was to investigate the growth of individual trees and the effects of thinning in a stand of spruce and pine. This was made through tests of regression between a competition index (CI), which depended on distance and diameter of neighbouring trees, and needle mass (NM), compared to basal area growth (BA growth) and dry-weight. The data used in this study was collected over the

Populärvetenskaplig sammanfattning En förändring i det rådande klimatet med en temperaturhöjning på grund av en ökad atmosfärisk CO₂-koncentration kan komma att ha en påverkan på skogar över hela jordgloben. Trädarter som är anpassade till ett visst klimat kan komma att spridas norrut då klimatet kan vara mer passande i framtiden. Detta medför risken att lövträd från central Europa kan konkurrera A climate change will affect the forests around the globe; there may be competitions for available resources that are needed for growth and dispersal. Europe is supposed to be more sensitive and may experience a greater influence than many other regions. As an additional effect of climate change extreme weather events will be more frequent e.g. drought and extreme precipitation that will cause flo

Populärvetenskaplig ammanfattning Den Arktiska tundran har påverkats mycket av klimatförändringarna de senaste årtiondena. Den pågående uppvärmningen gör att djupet på det aktiva lagret ökar och att buskiga växter, som annars inte trivs i den kalla miljön, vandrar in på tundran. Forskarna för att dessa förändringar kan leda till att de Arktiska ekosystemen blir en källa för koldioxid (CO₂), iställClimate change has affected ecosystem structure and composition in the Arctic during the last few decades. Researchers have observed a greening trend as the active layer depth is increasing due to rising air- and soil temperatures. Align with climatologic factors, Arctic ecosystems have a long history of grazing by large mammalian herbivores and geese. The Grazing Optimization Hypothesis suggests

Att anlägga en vallbesådd zon på 6-20 meter mellan vattendrag och åkermark, en så kallad skyddszon, är ett tämligen enkelt sätt att minska näringsläckaget från jordbruket och därmed minska övergödningen i sjöar, vattendrag och hav. För sådan typ av skyddszon har lantbrukare sedan 1996 kunnat få miljöersättning från Jordbruksverket för att kompensera förlusten i skörden på grund av minskad åkerareaCreating a 6-20 meter wide grass zone in between a watercourse and farm land is a fairly simple method to reduce nutrient losses and thereby also to reduce eutrophication in lakes, watercourses and oceans. This zone is called a riparian buffer zone. Farmers in Sweden have had the opportunity to apply for environmental grants from the Swedish Department of Agriculture for such buffer zones since 19

I dagens skola är grupparbete en vanlig undervisningsform. Diskussionen om grupparbete har länge varit av intresse hos både socialpsykologiska- som utbildningsforskare. Då grupparbeten idag är så pass vanliga syftar denna studie till att undersöka vilken gruppsammansättning som ger eleverna den bästa förutsättningen för en bra inlärning. I undersökningen genomförs ett experiment med elever studera

Nowadays the private sector tends to increase its engagement into social and environmental issues and cooperate with the public organizations in order to contribute to the development of the societies where the companies operate and also mitigate the environmental damages incurred by industry. The increase in social responsibility by private firms is generally articulated by and pursued through th

This thesis examines the Technical and Vocational Education and Training(TVET) related contents (including legal instruments and other guidance) from human rights bodies,ILO and UNESCO these three international bodies and also from China this national context. It analyzes the related legal frameworks of TVET from those sources and assesses their impacts in the national level, finally concludes the

Previous research on hydropower projects impact on people’s socio-economic development has mainly focused on relocated people, immediately after they were relocated, arguing that relocation result in underdevelopment of people´s livelihoods. Henceforth, this research contribute to the literature through including a long-term perspective to highlight immediate and long-term impacts on relocated and

Kockums is a leading company that develops military marine systems, for use both below and above the water surface [1]. Future submarines have a need to be operated more accurate than today’s submarines to perform various types of new operations. Therefore, on behalf of the conceptual design department on Kockums, a maneuvering system was to be developed to operate a submarine more accurate at low

In this thesis I examine pastoralists’ marginalization when it comes to land ownership in Tanzania, through a Minor Field Study based on interviews. The perception on pastoralism is since colonial times very negative and their way of living do not seem appropriate for the 21st century by the government. Pastoralists face a multitude of problems such as land alienation, degraded resources, conflict

Result This thesis has resulted in a new Project Management (PM) tool for the Scania Engine Development Project Coordination group, customized for engine development long-term test planning and tracking. The PM tool also shows resource use, capacity, and forecast of all Scania’s engine test benches located in Sweden, Germany and Brazil. Issue of study As a result of the continuously increasing

There is probably millions of photographs in the world that no one knows about because of the difficulty archivists have writing about them. It is exceedingly difficult to classify and describe photographs and very often textual models for written sources are applied uncritically to visual materials. Most libraries, archives and museums are now involved in the process of digitisation to improve ac

Ambitionen är att förstå hur det praktiska förhållningssättet till korruption inom kommuner kan se ut; och hur detta kan tänkas påverka hur riskerna för att tjänstemän skall agera felaktigt. Utifrån detta används därför de olika indikationer som tidigare forskning resulterat i och jämförs med vad som framkommer utifrån de intervjuades utlåtanden. För att kunna bilda denna förståelse används en ana

The first European macro-regional strategy, the European Union Strategy for the Baltic Sea Region (EUSBSR) was launched in 2009. The EUSBSR has been a role model for other macro-regions in the EU, which makes it relevant to study from a governance perspective. This thesis adopts a case study design with the aim of examining how the EUSBSR governance system can be characterised and in what ways the
