Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas. In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.

Over a long period of time, there has been a rich debate in the academic and financial world if active management can generate an excess return. Many experts say that the current active management strategies is nothing more than a money grab that produces large gains, for banks and investment firms, through high management fees while producing no excess value for the individuals buying their service. In short, an effective market makes it almost impossible for fund managers to produce value for their clients in the long run.No argument has only one side though, other experts say that active management has a role to play because not all investors are rational. This irrationality can lead to mispricing on financial assets in the marketplace and in turn lead to an ineffective market where active management can fill a much needed role. The purpose of this study is therefore to see if active management strategies can create a higher risk adjusted return, taking management fees into consideration, during times of high volatility when the uncertainty is at its peak.

Stora volymer förorenade sediment kommer att behöva tas om hand under de kommande åren då bottensediment i svenska farleder, hamn- och kustområden under lång tid har konta?minerats av både tungmetaller och organiska föroreningar. I examensarbetet studeras fyra möjligheter för hantering av förorenade muddermassor. De tre traditionella metoderna är tippning till havs, utfyllnad i vik eller deponering på land. Stabilisering/solidifiering (s/s) är ytterligare ett alternativ som innebär att muddermassorna kan nyttiggöras i geokonstruktioner genom att massornas hållfasthet ökas.

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.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

Background: Many companies have outsourced their IT-operations and their expectations of what this IT-outsourcing will contribute to the business are high. Cost cuts are not always a natural outcome of IT-outsourcing. Many companies that have outsourced their IT-operations consider it to be problematic and complex to exercise management control and reach cost control which was the purpose of the IT-outsourcing. Purpose: To describe and analyze what affect IT-outsourcing has on a company?s management control system and a company?s possibility to exercise cost control.

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.

Det saknas metoder att mäta informationssäkerhet inom företag och företagets tillgångar har förändrats från ett fokus på maskiner och råvaror till kunskap (intellektuellt kapital). Rapporten utforskar om det finns delar av företags intellektuella kapital som beskyddar företagets tillgångar och processer. Detta kapital kallas säkerhetskapital. Hur skulle företags informationssäkerhet kunna tydliggöras genom dess intellektuella kapital och hur kan begrepp inom informationssäkerhet och företagsvärdering hänga samman? Syftet med uppsatsen är att öka förståelsen hur informationssäkerhet är relaterat till intellektuellt kapital.

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.

According to a press release from the Swedish forest agency in May 2014, western Värmland has the worst regenerations of forest result in the whole of Sweden. The scarification frequency is low in the area. AB Hilmer Andersson want´s to know if the private forest owners want to scarify more than is done today. Good regeneration is important for private forest owners so they can have a long term forest management and economics of their forests. This academic study is done as an opinion poll. The purpose of the study is to see how big the interest of scarification among the private forest owner is.

Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.

Syfte: Syftet med denna studie var att ja?mfo?ra den initiala komforten mellan sfa?riska och asfa?riska stabila linser da? uppfattningen har varit att asfa?riska linser (med sin mer fo?ljsamma passform) borde vara bekva?mare.Metoder: Studien omfattade 30 deltagare med en medela?lder pa? 26 a?r. Med hja?lp av topografens (Topcon CA-100) kontaktlinstillpassningsprogramvara valdes en sfa?risk A- design lins (fra?n Nordiska Lins) och en asfa?risk A90 lins (fra?n Expert Optik, Sverige) ut med passande parametrar. Linserna sattes i vardera o?ga utan att fo?rso?kspersonen visste vilken lins som var vilken.
