ABSTRACT Infertility is a medical condition that affects approximately 16 % of Swedish couples in childbearing age and is a condition found in both men and women. When a couple has been trying to conceive for more than 12 months without success they need to see a health care provider. Infertility can be treated with medicine, insemination or assisted reproductive technology such as in-vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). The aim of this study was to validate a morphokinetic selection model, KIDScore? D3 Basic, against morphological selection model that is currently in use at the Fertility unit at University hospital in Orebro.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

The aim of this Bachelor´s thesis is to contribute to theunderstanding of the headmaster´s view of his role when it comes to developing the school library and in particular the work of integrating the library into the teaching. The basis is three questions: What views do the headmasters express regarding the libraries´ main functions? What views do the headmasters express regarding their own importance for the school libraries´ pedagogical role? How do the headmasters regard the interaction between teachers and librarians, as to how the interaction works? To get answers to these questions we conducted semi-structured interviews with headmasters of secondary schools. As a theoretical starting point, we used our own taxonomy for headmasters. The basis of our taxonomy are from the points by the ?Svenska biblioteksföreningen? and ?Kungliga biblioteket?, which together form a description of a school library integrated in the school curricula.

We have been looking at three different types of agriculture in Södermanland, in the middle east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is to get an economic defensible plan for how to run different farm sizes. We also have been looking at the working hours and how many hours the different types will give. We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is located 60 km southwest from Stockholm.

I denna studie har vi haft som avsikt att jämföra två modeller som förklarar avkastningen på aktiemarknaden. Modellerna är Capital Asset Pricing Model (CAPM) och Fama-French trefaktormodell(FF3). Undersökningen har gjorts på Nasdaq OMX Nordic Stockholm över perioden 2002 till 2012. Vi har valt att göra denna undersökning för att se huruvida FF3 med två extra faktorer kan förklara avkastningen på aktiemarknaden bättre än CAPM. Sex portföljer konstruerades och vi har visat att FF3 statistiskt signifikant förklarar mer än CAPM för fem av sex portföljer.

Accounting for financial instruments can either be based on a transactions approach or an eco-nomic approach. Under a transactions approach instruments are reported at cost whereas under an economic approach instruments are reported at fair value. Hence, under a transactions approach realization becomes a criterion for recognizing fair value fluctuations as revenue whereas under an economic approach it does not. A mixed model is defined as a combination of the transactions approach and the economic approach insofar it records some accounting items at cost and other items at fair value. The mixed model gives rise to an issue commonly referred to as an accounting mismatch.

This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

The purpose of this study has been to examine what it is in the situation that affects which leadership that is applied on the members of the organization. Our questions that we have explored were; What is it in the situation that influences the leadership applied on an individual or staff group? What similarities and differences have emerged by Hersey and Blanchards situational leadership model?Further, we used qualitative semi-structured interviews at the interview procedures with three managers and three employees. Hersey and Blanchards situational leadership model and Goffmans theory in the book "The presentation of self in everyday life" have been used as a foundation and inspiration in this study.We have found that circumstances like the size of the staff group along with the organizations financials and the resources affect the leadership behavior and how well it is matched with the employees. The function of the leaders position in the context, and the purpose of the situation influences how the leadership is formed.

Fuktskador på uteluftsventilerade vindar är ett ökat problem, i det mer miljömedvetna Sverige. Genom tjockare vindsbjälklagsisolering minskar både energiförlusten genom bjälklaget och uppvärmningsbehovet i huset, men hur många funderar på vad som händer med det förändrade klimatet på vinden och hur det kan påverka fuktförhållandena i utsatta delar av konstruktionen.Studier från Chalmers Tekniska Högskola har framställt ett fuktberäkningsprogram för uteluftsventilerade vindar vid namn Simple Cold Attic Model. Programmets funktion och potential har prövats i denna rapport genom en beräkningsanalys av en uteluftsventilerad vindskonstruktion. Försök till att förbättra fuktsäkerheten i konstruktionen har utförts och redovisas i rapporten. Studien har påvisat att den studerade konstruktionen inte är fuktsäker om den uppförs i Stockholmsområdet. Det visades även att aktiva val i konstruktionen kan förebygga fuktskador. Studien har påvisat vikten av inte beräkna med medelår för klimat och hur det påverkar beräkningsresultatet av mögeltillväxt.

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

Due to increasing international competition and new technology IT-consultants has been forced to oversee their business models lately. The main purpose of this study is to investigate the process and consequences of a shift in business model for a consultant by using a methodology based on action research. The empirical foundation consists of a field study with observations, notes, interviews and business related documents. The case describes a consultant?s process of shifting business model from profits based on man-hours to selling a standardized system.

?Medicines are available in different forms and often have different types of compound components. More and more drugs are found on the market. This means that professionals who handle different medicines must have access to more and more information.The information available includes information about side effects, active substances, interactions and pill identification. You may want to access different information, depending on your profession.

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.
