Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms
This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

Positive human to cattle interactions and the possibilities to increase animal welfare, economy and safety for farmers
Cattle production systems are changing to bigger intensified systems with larger numbers of animals per farm and more free range systems while at the same time employing fewer people. Aversive handling has been known to affect cattle production negatively for many years, but lately scientists have started to focus more on what positive effects gentle handling and positive human-cattle interactions may have on beef and dairy production. Fear can cause high stress in production animals and this can contribute to not only reduced production within beef and dairy cattle, but also increased risks for accidents and decreased animal welfare. Therefore, by reducing the fear cattle experience of humans, it could be possible to increase production, decrease accidents and increase the welfare of the animals. Reducing the animals fear and stress can be done by simple means, such as walking and talking calmly around the cattle, associating humans to positive feelings (such as feed) and stroking the cattle?s body regions associated with social grooming.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.
Elektronisk motorstyrning för ottomotorer
The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Stålfiberarmerad betong för platta på mark : -En kostnads- och sprickbreddsanalys
AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.
Tvåspråkighetsutveckling: Albansk-/svensktalande ungdomar berättar om sin utveckling av tvåspråkighet utanför skolan
We consider the meaning of leisure time for the human linguistic and cultural development of great meaning, in particular association with bilingual. We are both bilingual and have had the privilege to use and develop our knowledge likewise our experience during our education.The purpose with our school essay is to investigate what the youth tell us about their bilingual development outside School time. Our target group is Albanian-/Swedish speakers from upper secondary youth. Based on our own experience we know that upper secondary School contributes to an increasing awareness about themself and their own language and identity.In our empirical study, have we used qualitative strategy and build our interview guide on the basis of the semi structural method. Furthermore we have carried out two different group interviews which consisted each between 6-7 interviewees.
Hur står det till med jämställdheten? : En kvalitativ studie om arbetet med jämställdhet på grundskolor i Kronobergs län
This study is an assignment from the council of Södra Småland county to investigate how equality between boys and girls progresses at compulsory schools in Kronoberg county. The study was undertaken to find suggestions on how work with equality could best be stimulated.The key question was to elaborate how a decentralized rule and structural context of an organisation can affect an implementation of political decisions. The methodological approach adopted can be defined as inductive, it was analysed how the respondents from some selected schools in Kronoberg county themselves relate to the concept of equality between men and women and their experience and understanding of how the concept of equality between sex is understood in their work at school.School-legislation today demands that active measures are undertaken to promote equality between boys and girls and in general almost all the respondents of my study describe equality as an utterly important question. My findings although, at the same time, indicate a gap between rhetoric and practice. The findings of my study suggest that structural relations and a decentralised organisation can constitute a hindrance for implementing equality between men and women in schools.
Soil carbon, pH and yield development in a long-term humus balance trial
Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss
of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.
Remburser och andra säkerhetsarrangmang vid internationell handel
AbstractWe live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do transactions with people far away, and those systems is the core of this essay. As a private person you sometimes need to transfer money to family members who live abroad and you can then use clean payments. This means that banks all over the world has systems which makes it easier when their customs wishes to transfer money abroad.
Metodutveckling för planering och genomförande av dikesrensning med moderna metoder
?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes.
In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests.
So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland.
We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning.
A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests.
This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.
