Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Today we see a growing need and interest in working towards sustainable development. To be able to contribute to a sustainable development as individuals/business we need to emphasize the importance of education and contextualisation that learning occurs in a sense that is relevant to the learner.This is the background to this study, which in turn is the basis for an education that focuses on how to environmentally secure your purchases, an opportunity for us to set environmental standards purchasing products and services. The process for purchase is considered by many to be a key factor in businesses work towards sustainable development. Key people in this process and target audience for this education is environmental, purchasing and procurement managers.The purpose of this study is to design an education calledMiljösäkrade inköp from the target audiences? knowledge, interests and attitudes, together with literature.

This report is focused on marketing opportunities for small-scale mango farmers in the Nyanza Province in Kenya. Kenya is a large horticultural producer in the world. Horticulture is an important income for a large share of the rural population in Kenya but profitability is low due to inefficiencies in marketing systems and poor infrastructure. The conditions for growing mango in the Nyanza Province are very beneficial and there are two harvesting seasons. Mango offers good income opportunities for small-scale farmers in the Nyanza Province.The aim of this study is to identify marketing conditions that will enable prospering business for small-scale mango farmers in the Nyanza Province, Kenya.

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

This master thesis is about sustainable city planning and its debate. It is also concerned with networking, communication and web-based communication. Theories of sustainable development are discussed, along with the importance of communication for sustainable development. The report is directed towards landscape architects, architects, town planners, other designers and other interested readers.MotivationI believe that there is a need for an increased discussion concerning sustainability. Sustainable development is an important issue for city planners.

The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological restoration-project in a forest landscape.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

The aim of this study has been to describe the ongoing region enlargement process in the region Mälardalen, located in the east part of Sweden, and to investigate how this process can affect the local level. The study is especially orientated on public communications and accessibility. The intention has also been to examine how the local accessibility can affect the re-gional development in Mälardalen. The local investigation object that has been chosen for this research is the city Strängnäs, situated in the province of Södermanland. The city of Strängnäs and the cities in it?s near geographic surroundings has been the benchmark for this casestudy, in which the local accessibility with public transportation has been investigated.

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.

Since the Chinese economy?s reform in 1980, it has been attracting enormous foreign investments. Many Swedish firms from different sectors such as technology, manufactory production, consumer, service industries and so on, had started their investments in China. China has become the first choice for global manufacturing due to the huge market, continuous economic growth, stable political situation, sound investment environment and the WTO membership. In addition, China's enormous potential in finance, service, infrastructure, telecommunications, wholesales and retail industries will also attract a great deal of foreign capital.

Syftet med uppsatsen är att studera möjlig utveckling av kommunerna och tätorterna i Jönköpings, Kalmar och Östergötlands län fram till 2020, med utblickar mot framtiden. Bakgrunden till uppsatsen är de diskussioner som förs i Sverige kring nya regionkommuner, där sammanslagningar av befintliga län ska ske. I denna process är Östra Götland ett förslag för de tre länen och därför är det av intresse att studera hur dessa kan utvecklas i framtiden.För denna analys har tidsgeografiska utgångspunkter kombinerats med Christallers centralortsteori för att skapa ett tredimensionellt tillgänglighetslandskap. Detta har sedan legat som en viktig förklaringsgrund för hur tätorter utvecklas. Resultatet av uppsatsen visar att de som lyckats locka till sig nya invånare kan delas upp i huvudsak i tre grupper; pendelorter med goda kommunikationer till andra orter, förorter med kort avstånd till regioncentra eller residensstäder (undantaget Östergötland där både Linköping och Norrköping är tillväxtorter).

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.
