Prediktionsmodell för graviditet vid in vitro-fertilisering med ett frys-tinat embryo

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

Attitudes concerning conservation in two different wildlife areas in Kenya

All over the world, scientists agree that to succeed with a conservation project, it is important to have a good relationship with the local people. If they do not receive a good impression of the project, they will not be willing to collaborate and the project will probably fail. According to previous studies, there are different factors affecting attitudes to conservation, like the level of education of the participant. Many studies have shown that the higher education the people have, the more positive attitude they have to adjacent conservation areas. Economical factors are also important, it is often stated that having more money results in a better attitude.

Psykosociala faktorer som befrämjar återhämtning från alkoholberoende

Background: In scientific literature there are various treatment programs for people with alcohol dependence described, however, are psychosocial factors that promote recovery process described to a limited extent.Purpose: To describe the psychosocial factors that promotes recovery from alcohol dependence.Method: Literature study of ten scientific articles, published between 1999-2011 with both qualitative and quantitative design.Results: According to the literature, the recovery process can be considered to begin when a person with alcohol dependence reached his personal rock bottom. The longer the recovery progresses, the greater are the overall level of performance. Social support is described as an important factor to prevent relapse and reduce the need for professional help. Self-belief and support of self-help groups are described as important to maintaining sobriety. Social support and influence from family members was related to increased ability to analyze and assess their situation during the recovery.

Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning

Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made. A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

Lokalisering av vågkraftanläggningar : Metodutveckling med GIS och fallstudie Bohuskusten

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

Studie av dagvattenkanalen utmed Sjöstadsparterren i Hammarby Sjöstad

In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.

Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Samverkan mellan nya cementtyper och tillsatsmedel för betongtillverkning

Cement manufacture accounts for 3-5 percent of total global carbon emissions. There is a growing interest in reducing the environmental impact and conserve limited natural resources. In cement production, clinker productions consume 87.5 percent of the total energy consumed in the cement manufacture.Cementa has since many years, focused on reducing the environmental impact of cement production. The work has involved the entire production process from selection of alternative fuels to the development of cement with less clinker content. During 2013/2014, two new types of cement (Bascement and CEM II / B) will be introduced to the Swedish market.

The road to recovery : En fallstudie om Arla Foods krishantering i Mellanöstern

The aim of this thesis is to expand the understanding of 16th century Flemish art by approaching paintings by artists Pieter Aertsen (1508-1575), Joachim Beuckelaer (1533-1574) and Pieter Bruegel (c. 1525-1569) from a different perspective. This is done by extending the discourse of art history, into a discourse of literary history and primarily 16th century novels by authors such as François Rabelais and Miguel de Cervantes. The paintings are studied in relation to these 16th century novels, by comparison and as a testament of this specific time period. A widening contextualization is also constructed in which a connection to the expression of the carnivals ambivalent form, as well as the notion of lower classes is explored.

Secondhandapparnas dilemma: milj?hj?ltar eller konsumtionsdrivare. Analys av secondhandappars inverkan p? unga vuxna kvinnors konsumtion

This thesis examines how marketing by secondhand apps affects young adult women's consumption habits, investigating whether these platforms promote or counteract overconsumption. While the secondhand market is considered more sustainable than buying new, these apps may still encourage overconsumption. The study focuses on the marketing strategies of three major secondhand apps in Sweden: Tradera, Sellpy, and Vinted, analyzing their impact on consumer behavior using the AIDA model (Attention, Interest, Desire, Action). Based on qualitative interviews with eleven women aged 20-27 and the authors observations of the apps marketing activities, the study finds that secondhand apps often emphasize environmental benefits and makes secondhand shopping accessible and appealing. However, the marketing tactics used by these apps, including frequent push notifications, targeted advertisements, and influencer collaborations, may lead to increased consumption. Overconsumption causes significant environmental damage, and while the secondhand market can mitigate these effects by extending the lifecycle of items, the emphasis on convenience end environmental benefits can inadvertently encourage more consumption. The study concludes that secondhand apps play a complex role in consumer behavior, balancing the potential for sustainability with the risk of promoting overconsumption.

Allt finns på Internet En undersökning om biblioteksanvändande hos studenter på Chalmers Lindholmen i Göteborg.

The purpose of this master's thesis is to investigate how the students at Chalmers University of Technology at Lindholmen in Gothenburg use libraries in their schoolwork. The empirical material consists of the answers of questionnaires that were handed out to two classes of students, on the second year of their education. To illustrate the topic there are a theoretical frame and examples of earlier studies. The theoretical frame is Limbergs texts that deal with for example information seeking and how important it is in all education. The earlier studies are about student's different ways of using libraries.

Värmeledningsförmåga hos betong

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed.
