Klistret i klustret : En undersökande studie av ansamlingen av GIS-relaterad verksamhet i Gävleregionen
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Förutsättningar för småskalig solelproduktion i Australien
The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.
Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?
Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water.
The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission.
The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed.
Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed.
As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting).
The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture.
Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied
with 0.8 L per week.
Förslag till förbättringar av materialhanteringen kring packningslinan hos Spaljisten AB
The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda.

They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.
Inventering av värmelager för kraftvärmesystem
When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.
Fundamentalism och terrorism ur strukturella förändringar, förhindrad subjektivitet, produktion och reproduktion av diskurser Ett alternativt analytiskt ramverk för konfliktlösning
This essay criticizes common theories within the three traditional perspectives, conflict management, conflict resolution and conflict transformation, for not being able to explain and/or generate solutions to the problems of fundamentalism and religious terrorism in a satisfying manner. This essay is trying to synthesize an alternative analytical framework that better can explaining these phenomena and generate potential solutions. The frameworks ontological ground is laid out using different readings of Foucault, thereby seeing the subject as formed by discourses, material processes and institutions. Fundamentalism and terrorism are seen as a violent resistance to repressed subjectivity, but the form of resistance depends on the discursive and non discursive surroundings. This gives rise to different forms of resistance; the production of discourses and founding of groups and the entry of marginalized people in these groups.
Produktionskalkyler för biobränslen :
This study is one of five that has been done based on Lunds Energi?s planned investment
in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be
supplied with biofuels.
In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage
sludge.
Avelsarbete med mjölkproducerande getter ? fokus på Norge och Frankrike
The main part of the goats in the world is located in developing countries, whereas active breeding programs are mainly restricted to Northern America and Europe. Goat milk can be processed to several products and goat cheese is the main product. An organized breeding program is carried out in France and Norway but is not present in Sweden. Important selection traits for milk producing goats include milk, protein and fat yield along with protein and fat content. Functional traits have been more important the past years and they have large economic importance for the farmers.

Kundorderstyrd tillverkning ? Påverkande faktorer, förutsättningar och problem : En övergripande studie om hur små och medelstora företag flyttar kundorderpunkten och går mot mer kundanpassning.
This study presents a holistic view of which factors small and medium-sized enterprises (SMEs) have to consider, in moving their customer order decoupling point (CODP) further from the customer, thereby becoming more customized. The study also investigate whether SMEs and larger enterprises differ in the strategic questions relating to what influences an enterprise to become more customized, which prerequisites are required and which problems enterprises should anticipate and prepare for. These questions are important, given that strategic change is challenging, and can take considerable time to accomplish; it therefore needs to be based on the right decisions. This study is motivated by the fact that the markets SMEs are selling to tend to become more and more complex and harder to anticipate. Increased globalisation and use of IT and ICT have lead to greater uncertainty in customer demand.
Valmöjligheter i samband med prefabricerade badrum
This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.The recent problems with damage caused by damp in bathrooms. Have resultade in regulations.
Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
Sensorer och system i mjölkkobesättningar : en litteraturstudie
The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.
Impact of hygiene training on dairy cows in northeast India : en hygientränings påverkan på mjölkkor i nordöstra Indien
Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.
Prosodisk förmåga hos svenska grundskolebarn med cochleaimplantat
Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different.The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing.
