The economic consequences of Striga hermonthica in maize production in Western Kenya
Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.

Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation
Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.
Framtidens elnät : Hur elbilar och solceller påverkar på det lokala elnätet
The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.
Tillförlitlighet hos information som hanteras av flera användare och genom flera system
When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..
Human Stem Cell - European National Innovation Systems and Patents
The purpose of this paper is for the reader to realise how national innovation systems are deeply intertwined with the legal background of a country and to understand the processes that involves national innovation systems specifically regarding the stem cell / genetics research and how the need for specific community law must be considered targeting the stem cell patents. The legal part will try to answer: Why is it important given the actual state of the European stem cell national innovation systems for the European Commission to take a stand and tackle issues regarding the patenting of the human stem cell innovations? This is done from a country industry analysis (business approach) and then linking it with competition law from a community stand point of view (that tackles biotechnology issues). In order to achieve this the paper is divided into three separate analyses beginning with a theoretical background of general biotechnology / genetic terms that will enable the reader to have a general understanding of the importance of this kind or research ( genetics / stem cell research). The chosen countries case studies exemplify very diverse economies and development perspective from the traditionally R&D intensive to the least and from the biggest countries in Europe to one of the smallest, thus giving cultural, legal, economic and scientific variety..
Förutsättningskontroll och nedbrytningstest på oljeförorenad mark : Preem 2, Karlstad
More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).
Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader
The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
Wool loss in sheep
The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Vinstdelning: En studie i hur affärsjuridiska advokatbyråers vinstdelningssystem är uppbyggda och hur valet av vinstdelningssystem påverkar organisationen.
In the last couple of decades, corporate law firms have rapidly grown to become both influential and highly profitable corporations in the business world. Today, the largest law firms are assumed to bear far greater resemblance to large and often multinational public limited companies than the small businesses generally associated with legal services. However, one interesting specific set them apart from the majority of other companies; the partnership and its interrelated profit sharing. The aim of this study has therefore been to investigate partner compensation systems in corporate law firms and further examine what implications chosen compensation systems have on the organizations. Using a multiple case study, including 7 of Scandinavia?s largest and most well known law firms, the results show that partner compensation systems are highly individual and the critical question is whether to employ seniority based or performance based compensation systems.
ISO 14001 : Från ledningsbeslut till certifiering
Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.
Termisk analys och förbättring av ECU enhets kylflänsar till förbränningsmotorer
Detta examensarbete har utförts inom programmet högskoleingenjör maskinteknik på Karlstads Universitet under våren 2014 för företaget Prevas Development AB i Karlskoga. Syftet med arbetet är att optimera utformningen av kylflänsar som sitter på en ECU enhet (Electronic Control Unit) som är en komponent till fordonsindustrin. Förbättringen skall tas fram genom att använd en programvara som kan genomföra termiska simuleringar. ECU enheten består av en låda med en överdel som består av kylflänsar som har till uppgift att kyla ner kretskortet med dess olika komponenter som sitter inne i ECU enheten. En termisksimulering har utförts på den befintliga utformningen, resultaten från den simuleringen jämförs sedan med resultatet från de termiska simuleringarna som utförs på nya utformningar som tas fram.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.
SELF CONTROL
SELF CONTROL är ett undersökande examensarbete i textildesign. Med en textil hantverksmetod undersöker jag mötet mellan kontroll, tidsåtgång och material. Detta med utgångspunkt i en feministisk diskurs. Jag ser kontroll som något som exkluderar, censurerar och begränsar möjliga uttryck inom textilt hantverk på samma sätt som kvinnokroppen kontrolleras i ett patriarkat. Jag har använt mig utav en performativ och repetitiv metod som aktivt har gått ut på att bryta mot föreställningar om hur hantverket ska utföras.
