Smarta prefabmoduler för småhus i betong

This report examines the possibility of developing a modular system for concrete homes that cancontribute to greater diversity of today's market. The issue was whether it ? from a competitive pointof view ? is possible to produce smart prefab modules that customers themselves can combine to avilla. The report addresses the question how the modules and wall panels should be designed for thegreatest variety of floor plans.With regard to what is asked of the customer interviews where held for the purpose ofunderstanding concrete's popularity and elements of high value in their homes today. The answersfrom the interviews laid ground for four prototype homes which were made to demonstrate how theelements can be combined to achieve different types of houses..

Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)

Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

(O)motiverad Invandrarpolitik : en studie om motiven att frångå invandrarpolitik och införa integrationspolitik

An effective Integration policy is important in Sweden while our government has decided and committed to be a country where everybody will be given the same opportunities. There is a greater awareness in today?s society of integration policy goals such as equal rights, responsibilities and opportunities for all. In a number of areas, however, the disparities between immigrants and Swedish-born citizens are still too large.The Swedish Riksdag decided on integration policy in 1997. The main task for this thesis will be to examine the motive behind the Government's decision to revoke immigrations policy and introduce integration policy.

Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia

There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the Biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

Effektivitet i team : omsorgsgrupper jämförda med andra svenska arbetsgrupper från en större population

Richard Hackman and Erin Lehman (2005) in order to diagnose the strengths and weaknesses in work-groups, as well as explore the group?s behaviours and effectiveness. The results show that there was a significant difference between the Karlskrona Kommun groups and the larger population of Swedish groups in the following areas: stable, clarity, challenge, diversity, whole task, resources and availability..

Är yrkesverksamma tandhygienister i Sverige intresserade av att komptetenshöja sig genom utbildning?

ABSTRACTThe aim of this study was to ascertain whether there was any interest among dental hygienists, raising their level of competence throught attending additional courses or gaining further qualifications. The study was carried out by sending out two-hundred questionarires to randomly chosen dental hygienists. After one remainder come the answer frequency up to 66%. The study shows that many of the dental hygienists are interested to study at college. Many wanted raising level of comtpetence by education, wich also the study shows.

Restriktioner av växthusgasemissioner : hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?

The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.

Närsaltsdosering till luftad damm : en åtgärd för ökad TOC-reduktion hos Skoghalls Bruk luftade damm

In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.

Styrelsens unika kompetensbehov : En studie av kompetensförändringen i styrelsen

Background: The board of directors is a key player in corporate governance. Their role is to ensure that the corporations are run with the interest of the shareholders as the main focus. In the beginning of the 21st century, a survey was made about the confidence of the Swedish business community and in which criticism was directed to the board of directors. The boards were deemed inadequate in their function and were often solely composed by members with similar experiences and competence, therefore lacking in diversity. In order to improve the competence and work of the board of directors, the Swedish code of corporate governance was introduced and its recommendations comprehend the boards? size and composition.

Synen på mångfald och jämställdhet vid vägverket

Research has shown that still today mostly men inhibit the managing director positions and jobs such as electricians, engineers, and road workers, which makes the work situation unequal among those work places. Another issue is that studies show that minority groups have fewer possibilities in comparison with majority inhabitants on the labour market. One reason can be that many companies and organizations lack when it comes to the recruitment process due to prejudices and the applicants for a job who has names such as Ahmed, Carlos and Ali are taken out of the process at first stage.The purpose of this research is to study how civil servants at Vägverket (Swedish Road Administration) discuss about diversity and equality. Whereas subjects such as ethnicity and gender will be illuminated..

Identitetsskapande : en analys av sex ungdomsromaner med homosexuella huvudpersoner från 1977-2003

The purpose of this study is to analyze how homosexuality is portrayed in young- adult novels. I use books published in Sweden from 1977- 2003. Three of the books have female main characters and the other three have male main characters. My purpose is therefore to compare the different results between the sexes.I will examine and discuss the homosexuality in the novels with focus on the homosexual identity of the young characters and how it is formed.
