Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

This thesis attempts to describe the application of variation theory, as developed by Ference Marton, at a Swedish primary school, intermediate level. The aim of the thesis was to investigate some aspects of a learning process. The students were introduced with the theme of ?sustainable ecological development?. This included theoretical and practical knowledge of the art of sustainable living.

There are mainly two ways to transform the design of an existing park. You could either make a replanning of the park, an act that changes the design and the plant material in one swoop. Or you could use the management to change the expression of the park. To be able to develop the parks with the help of management, some form of goal is needed, that can make the management of the park strive towards an expression for the whole park as well as its individual parts. Among the documented goals, for individual parks and park management, which exist in the municipalities today, there seems to be a weak link between the all-embracing goals and the management that is carried out in the parks.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

Background: Obesity has expanded to a nationwide issue that affects millions of people. The healthcare system struggles to handle the epidemic as the problem grows. Studies show that healthcare workers have negative attitudes toward obese and overweight people and that they lack knowledge and proper tools to support this patient group. Motivational interviewing (MI) is a known technique for initiating lifestyle changes with patients. Aim: The aim is to evaluate the effectiveness of MI as a tool for weight loss and sustainable lifestyle changes for people with obesity and overweight. Method: This study uses a literature review methodology with a systematic perspective. Data is gathered and analyzed to investigate how MI affects weight loss.

Datorspel har under början av 2000-talet tagit världen med storm. Fenomenet har exploderat från att vara en angelägenhet främst för de redan frälsta till en internationell miljardindustri. Sverige är en av de bästa länderna i världen på datorspelsutveckling. Alla som vill kan dock inte genast ta del av underhållningen. Ett funktionshinder kan försvåra eller helt förstöra spelupplevelsen.

The purpose of this study is to investigate what knowledge children in preschool have about recycling, and to examine how teachers work with environmental efforts to increase children's understanding of environment and sustainable development. And if there is differs between the two preschool classes, one of which has a environmental profile. The study is based on qualitative semi-structured interview methods of teachers and children, and observation of the children during a sorting exercise with a number of garbage objects. The result shows that teachers in the environment profiled preschool spend more time per week on work related to environmental and natural issues and worked more thematic. Similarity between this preschool classes is that the use of outdoor education to get into environmental awareness.

In non-profit organizations, surplus of the organization goes back to the organization's members. We have noted that Hyresgästföreningen initiated a change in 2005 when the organization merged its local membership registries to a national registry. There are few studies explaining how non-profit organizations are using management in an organizational change. What happens with the business management at an organizational change that is similar to the change in Hyresgästföreningen? The aim of this thesis is to explore how the governance of a nonprofit organization is changing at an organizational change.

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

Ledning och övriga anställdas upplevelser av attraktivitet på arbetsplatsen ?Mora of Sweden? looks at how management and employees at the Swedish manufacturing company ?Mora of Sweden? perceive an ideal attractive company and what factors that determine one, as well as how these two groups perceive the situation at their own company.

Tidigare forskning har visat på att konkurrensen kring talangfulla medarbetare aldrig förr varithårdare och att ha strategier för att behålla dessa blir därför viktigt. En strategi som syftar till att görajust detta är talent management. Men hur arbetar man med detta och vilka föreställningar kringfenomenet finns? Vilka faktorer kan finnas som hindrar och/eller möjliggör arbetet med talentmanagement? För att ta reda på detta har det i studien valts att göra en fallstudie där data samlats ingenom semistrukturerade intervjuer. Det framkommer i studien att talent management upplevspositivt då det ger erkänsla och uppskattning.

Sapa Heat Transfer is a company that produces aluminum heat-exchanger strips for the automotive industry. Sapa Heat Transfer wish to chart their emissions of carbon dioxide in order to meet future demands on carbon dioxide reporting. They also would like to examine the meaning of the term ?green electricity? which is marketed as carbon dioxide free, and the sort of electricity that they purchase. This report includes both direct (liquefied petroleum gas and diesel) and indirect (water, process-water, long distance heating, waste) emissions from their company.

Den höga andelen hårdgjorda ytor i urban miljö bidrar till ökad belastning på dagvattennätet vid kraftiga regn och vid snösmältning. För att minska belastningen och förhindra översvämningar i urbaniserade samhällen kan grön infrastruktur införas, till exempel gröna (vegetationsklädda) tak. Gröna taks prestanda i kalltempererade klimat är ett område ej studerat i vidare utsträckning vilket bidrog till examensarbetets syfte med undersökning av ett grönt tak placerat i centrala Luleå. Genom en flödesmätare vid avrinningsutloppet från det gröna taket samt ett uppskattat flöde från ett intilliggande plåttak kunde de ackumulerade avrinningsvolymerna beräknas och jämföras. Det uppskattade flödet från plåttaket beräknades med takets area och SMHI:s nederbördsdata från Luleå Flygplats.
