From wheels to walking : exploring an alternative planning approach in Sub-Saharan countries - the case of the Axis in Nairobi, Kenya
Rapid urbanisation is putting strains on both the landscape and the city dwellers and the pressure on planning for sustainable and equitable cities is crucial. As many cities in Sub-Saharan Africa are expanding, city planning has trouble keeping up to meet the needs of the growing amount of urban dwellers. Many cities have also been planned with the cars in focus and the needs and comfort of the pedestrians have been overlooked. The capacity of institutions is limited due to centralized government and bureaucracy, as well as corruption. Planning is erratically implemented and it is difficult to know what will happen.
Säsongsvis avverkning : det operativa traktvalets påverkan på den säsongsmässiga uthålligheten i ett bolagsdistrikts traktbank
Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical.
The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank.
The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data.
The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.
Alice Springs drivet av solenergi - En jämförelse mellan solceller och Stirlingsystem
In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.
Transportekonomi : Underlag för prisförhandlingar
The report addresses four main tasks, situation analysis of the company's total costs and transportation volume, cost analysis associated with the adjustment of the filling ratio, transport costs for the expansion and new expenses on a combination of expansion with new adjusted filling ratio. Increasing transport costs for the company was the main reason for the request of the current situation analysis. A survey of the total cost with the actual volumes and transport provider pricing is the basis of the analysis that extends from May 2006 to October 2008. The results show an increase in costs, both overall expense and per cubic meter of transported goods. Volume spreads, trends, and seasonal variations are according to our and the company?s expectations.
Omloppstid för returenheter
Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.
Torkning och pelletering av organiskt hushållsavfall - en konstruktionslösning
The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

Ekoturismens inverkan på miljömässiga attityder och beteenden : En kvalitativ studie om individers erfarenhet av valskådning
The purpose of this study is to examine if the experience of whale watching can lead to increased knowledge of environmental problems. We also want to find out whether increased knowledge in turn could lead to changing environmental attitudes and behaviors.

The paper also has a section where previous research on ecotourism impacts on behavior and attitudes is discussed and subsequently addressed in the analysis section.Data has been collected through a case study where seven semi-structured interviews were conducted with individuals who participated in whale watching. The results show that all respondents had greater knowledge of whales by their experiences, the degree of knowledge was due to respondents' prior knowledge.
Gröna broar : ekologiska, sociala och estetiska tillgångar
The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.
