The impact of climate change on agriculture in the Republic of Mauritius : a socio-econometric study on Mauritian farming
"Food security is a situation that exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life" (FAO Summit, 2003, pp. 28).Food insecurity is of concern regarding the Republic of Mauritius (ROM) since it is defined as a net food importing country. (Farming news, 2008). The impacts of climate change followed by their complexity could potentially have an increased risk effect upon the social and environmental welfare as well as the economic drivers in the ROM (www, UNESCO1, 2009). The primary victims when it comes to the impacts of climate change are the Mauritian agricultural producers since agriculture is highly dependent on climate stability, therefore affecting the yields of the producers.
The potential of entomopathogenic fungal isolates as an environmentally friendly management option against Acanthoscelides obtectus
The bean bruchid, Acanthoscelides obtectus is a major threat to bean production.

In the present work the aim was to examine if the four chosen fungal isolates, B.
Säkerhetsanalys av brandbekämpning i kritiska utrymmen på Forsmark 1
In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.
Mindfulness i organisationer - en studie av upplevda effekter
The idea of bringing mindfulness into organizations has become increasingly popular. While previous research has shown positive effects of mindfulness practice in individuals, consequences of introducing mindfulness in organizations remain largely unexplored. This thesis examines those consequences through a qualitative study. We conducted semi-structured interviews with members of two case companies. Based on the effects which mindfulness has been shown to have on individuals, our analysis was especially focused on the areas of efficiency, effectiveness and organizational culture.

Kommunikation mellan patient och sjuksköterska : Faktorer som påverkar
Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.
Skolans fysiska miljö och hur den påverkar elevernas skoldag : En studie från två skolor
This study aims to examine what students in two schools think of the physical environment in their school, and how this affect their studies. My main question I wanted to answer was:How does the students think that the physical environment affect their day in school?I also wanted to find out what the students think is important in the physical environment in their school. The study is based on interviews with students i two different schools. One secondary school, in which three eight-grade students were interviewed, and one high school in which two students were interviewed. The result of the interviews is that the students think that their work in school is affected by the physical environment. The most important things is to feel safe in school and to have the possibilities to do studies without limitations in the environment, for example room to do their own studies, and a flexibility and variation in the environment.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.
Laserskärning i Sverige : ? tekniken, marknaden och hur de utvecklas
Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.
Kvalitetssäkring
This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.

Ersättningsnivåer - En studie av fast och rörlig lön till verkställande direktörer i svenska börsnoterade företag åren 2001 till 2005
Background and problem: Whether or not the pay to executives is fair is widely debated. During the last years especially the variable pay has been in the spotlight. But at what levels are the compensations really at? Media?s focus is mainly on the absolute highest compensations which may result in a skew view on pay-for-performance incentives.Purpose: The purpose of this thesis is to establish the levels of compensation to executives in a wide range of randomly selected companies listed on the Stockholm stock exchange during the years 2001 to 2005. Furthermore, the impact of a set of firm specific variables on compensation levels will be analyzed with basis in several hypothesis.Delimitations: The variable pay considered in this thesis will only be variable cash bonuses.
Drömmar med vingesus : - en undersökning av gymnasisters förståelse av äldre ord i Luciasången
This thesis work involves a quantitative study concerning secondary school students' understanding of older Swedish words in the lyrics in the Lucia song written by Elmfors way back in 1919th. The text has some old words and phrases that today's high school students do not really understand. The study includes surveys of two different classes in high school, a theoretical and a practical program. In some cases students can understand words by the context, but previous research shows results in general weakness in students' existing vocabulary. According to previous research, this is due, inter alia, that young people read and write less today.The results of all students are totally 38%, where the theoretical program has a slightly higher performance.
