The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: Can nutritional support contribute to the healing of pressure ulcers in elderly patients?Author: Anton Kinnander, Sandra SmidelikSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 12-04-11Background The number of elderly patients with co-morbidity is increasing in the western world. It is therefore reasonable to predict increasing incidence and prevalence of pressure ulcers. One study, published 2009, found that as many as 59 % of geriatric patients within the Swedish health care system had developed pressure ulcers. Symptoms vary from mild erythema to severe deep tissue damage and development of pressure varies from hours to weeks.

This report is the result of a thesis performed at Westermo Industrial Ltd with its headquarters in Stora Sundby and it sums up the author's studies for University Engineering in Innovation, Production and Logistics at Mälardalen University.The main goal of the thesis was to identify problems and suggest actions that lead to the reduction of the repair time from 3 weeks to 2 weeks. The key questions that were answered in order to achieve the thesis objectives are: What are the biggest challenges that make the repair process time last for 3 weeks? What are the necessary means and measures in order to reduce the repair length to 2 weeks? The author adjusted the work to the Swedish repairs, repair issues that arise from sell unit Westermo Data Communications AB with its office in Västerås and performed the status report by mapping the repair process, through using observations, interviews and bibliography research studies. A flow map of four sub-processes (Inbound Delivery, BackOffice, Repair Department, and Logistics) was made and each section was observed, where also the employees were interviewed. Data that has been collected was analysed by the author and the decision to execute a workshop that affects Repair Department and Logistics was made.

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

I en hårt konkurrensutsatt internationell marknad som kretskortstillverkning gäller det att vara effektiv. Därför tog ledningen för Ericsson Katrineholm under år 2005 beslut att Lean Production skulle införas i verksamheten. Den ökade fokuseringen på produktivitet ledde till att flera problem kopplat till ytmonteringslinorna på avdelningen Module Production & Engineering identifierades. Avdelningen fann att ställarbetet mellan olika produkttyper genererade onödigt långa produktionsstopp som i sin tur begränsade avdelningens möjlighet att minska batchstorlekarna. Syftet med examensarbetet har därför varit att reducera ställtiden mellan olika produkttyper vid ytmonteringslinan för volymproduktion. Detta ska i sin tur nås genom att framställa och implementera ett antal förbättringsförslag. Arbetet har i huvudsak varit av kvalitativ art, med kvantitativa inslag som underlag för ABC-klassificeringen samt uppföljning och tolkning av den genomsnittliga ställtidens utveckling under år 2006. Analysen har genomförts i enighet med SMED-metodik där internt och externt ställarbete vid ytmonteringen först kartlagts innan ett antal förslag lagt fram för att förbättra de olika aspekterna av ställarbete.

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.

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.

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

This master thesis deals with steel girders subjected to patch loading caused by concentrated moments. There exist no good methods to calculate by hand the ultimate resistance for this load case. In ?tunnplåtshandboken?, (Handbook for sheet metal, which is published by SSAB), one calculation method is presented. It?s however fairly difficult to use, because of many calculation steps and many graphs.

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.

In November 2007 the countries around the Baltic Sea signed the Baltic Sea Action Plan (BSAP). The action plan was an initiative from HELCOM due to the environmental status in the Baltic Sea. The action plan implemented a new approach with measures targeting the whole ecosystem. Eutrophication, hazardous substances, biodiversity and maritime activities constituted the main segments. The parties were to establish national implementation plans to fulfil the BSAP goals, which shall lead to good environmental status in the Baltic Sea by 2021.  The aim of this thesis is to investigate the points in common regarding conceptions of eutrophication in the Baltic Sea between the management, the science, the media and the public.
