Students? performance in school is dependent on the indoor climate. This report studies four schools regarding air quality and thermal environment. A survey was made at the schools as well as measurements of carbon dioxide, dampness, thermal climate and, as an indicator for the furniture?s capability to collect dust, shelf factor and fleece factor.

Vatten är en av jordens livsviktiga resurser, en resurs som hela tiden minskar. I delar av världen råder akut vattenbrist och ofta återfinns industrier med hög vattenanvändning i områden med begränsad vattentillgång. En av dessa industrier är textilindustrin. Vid textil beredning är vattenförbrukningen mycket hög och avloppsvattnet är ofta mycket förorenat. Vattenfrågorna inom textil produktion har fram till idag inte uppmärksammats i lika stor grad som arbetsrätts- och kemikaliefrågorna.

Our purpose with this paper has been to analyse and discuss how motivation of the personnel affects the service quality in service companies. This has been done through two studies; a literature study with existing theories and an empirical study on the divisions of Lyckohjul and Shopping at Liseberg. In the introduction of this paper we put the question of research; why is there a need for work of motivation in service companies. When collecting information we used literature briefing, a questionnaire study and depth interviews. The literature briefing focused on the well-tried and most dominating theories on the subject motivation.

Swedish government aid is divided into three main themes: democracy and human rights, the environment and climate, and gender equality and women's role in development. These three themes in aid are considered by the government to be vital in order to fight poverty and create fair and sustainable development. This study will examine two of the four focus areas designated under the theme of "environment and climate". The study observes the relationship between projects in energy and water and how it promotes a sustainable lifestyle. A survey on environmental habits will be conducted.

This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

The water tower in Uppsala city forest was built in the late 1950's in what is now a nature reserve. The unique place was supposed to be visited by people, which is currently not the situation. This bachelor thesis aimed to perform an analysis and make a design proposal for the environment surrounding the water tower. The analysis was performed using the methodology previously described by architect Arne Branzell. The methodology focuses on how a space is perceived by a person moving through it.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Restrictions in nature conservations are increasing the influence of forest management. Nobel broadleaved forests are more influenced than other forests, because they are considered to be more valuable than other forest types in Skåne. There has been a lack of knowledge about the amount that is set-aside for nature conservation and what types of forest that is concerned. These are the main questions to be answered in this thesis. Moreover has the timber quality been compared between set-aside and non-set-aside areas since it affect the financial conditions for the forestry in nobel broadleved forests. The last asked question deals with the financial consequences of set-aside.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

Due to deficiency in dementia care, the government has commissioned the National Board of Health and Welfare to develop national guidelines for health care services to people with dementia and support for their relatives. It has been allocated stimulus funds that may be applied for to work on improvements in dementia care. In August 2010 these guidelines formed the basis for a decision made that collaboration would take place between the county and the municipalities regarding dementia care in Halland, named Anna's path. The aim of this study is to investigate, analyse and describe how our respondents in the project Anna?s path are planning and preparing for the implementation of the registry of quality BPSD - Behavioural and Psychological Symptoms of Dementia.

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

Organic animal husbandry has received a lot of criticism lately. The aim of this literature review was to examine if the rules and principles of organic pig farming give better or worse welfare in comparison to the conventional systems in Sweden. Health, physiology and behaviour have been used as indicators of welfare in this study. This is due to the importance of using more than one indicator in welfare assessments. Studies have shown that organic pigs have more remarks on joints when slaughtered, but these remarks can be reduced by vaccination against erysipelas.
