Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.

Corporate Social Responsibility (CSR) refers to adjusting corporate goals so that they are not only based on maximizing corporate profits, but include ethical standards on socially desirable behavior (Boatright, 2008). Even though many companies have integrated CSR into their business operations, there are still many issues that are difficult to tackle. Especially Multinational Corporations (MNCs) in the global business environment face many challenging situations due to the fact that they often have linkages to countries where the local government is either unwilling or unable to take care of its responsibilities. MNCs often find themselves with increased responsibilities when they start solving some of the issues that earlier have been the sole responsibility of states. A specific case situation discussed in this paper is related to ?conflict minerals?.

The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.

This thesis examines a project that has been conducted at a software development company. The aim is to investigate which problems firms of this kind faces performing projects. We choose a theoretical frame consisting of a modern view on how to manage projects. The view argues that the management of each project has to be adapted to the situation at hand. This theory is divided into two separate streams of reasoning; one emphasize learning, delegation of responsibility and flexibility, while the other argues for control, time planning and the importance of keeping to the plans.When we compare the theories to the case we draw three main conclusions: A thorough phase of investigation is required to produce the necessary planning documents.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.
