Afrikas klimat : med fokus på Västafrika
Då de flesta människor i Västafrika, framför allt de som bor innanför kustzonen, livnär sig på jordbruk så är pålitliga väderprognoser och säsongsförutsägelser ett viktigt hjälpmedel i det dagliga arbetet och planeringen. I den här rapporten har en litteraturstudie gjorts för att öka kunskapen om de komplexa, både lokala och storskaliga, väderfenomen som ger upphov till nederbörd i området. Klimatet i Västafrika, ett område som mestadels täcks av regnskog eller savann, präglas av den västafrikanska monsunen som ger regnperiod under norra halvklotets sommar och torrperiod på vintern. Denna monsun visar på stor årlig variation när det gäller dess inledande faser, och prognoser som kan förutsäga dess början är nödvändigt när en jordbrukare ska planera säsongens verksamhet. Av många bidragande faktorer framgår det tydligt att ytvattentemperaturen i Guineabukten är en av de viktigaste parametrarna för monsunens startskede. Den intertropiska konvergenszonen, ITCZ, betraktas som monsunens nordligaste del och denna konvergenszon gör en plötsligt och relativt snabb förflyttning norrut, i fortsättningen benämnd som språnget, över ca 5 breddgrader, vilket av många ses som starten på regnperioden.
Outbreaks of African swine fever in domestic pigs in Gulu district, Uganda
The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential.
African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.
Sömn, depressionssymtom, livskvalitet och Alzheimers sjukdom
Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.
Konstruktion av yttervägg med vakuumisoleringspanel
This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..
Utformning av sidoområden med hänsyn till vägens livscykelkostnad
Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Further results are that the quality of design, installation, maintenance and inspection of sprinkler has to be improved and that the Swedish incident report has to be revised..
Fodder to ruminants within agroforestry systems in Rwanda - species and management
Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
Allt har förändrats men ändå ingenting
Everything has changed, yet everything is the sameUsually, there is no reason for people to think about death or illness, although it is a highlynatural part of life. Most people live in health without major problems. When something does happen, people assume it will be at the end of their life and then it will be a natural part ofgrowing old. Yet some will get the notice or the feeling that something is not the way it should be, it can be something they can live with or they may have to face death.The work concerns the body?s fragility and feelings about human vulnerability.
Ett steg framåt, två steg bakåt? Direktiv 2005/29/EG:s effekt på det svenska konsumentskyddet inom marknadsrätten
På EU:s inre marknad ska fri rörlighet råda. Trots det tvekar konsumenter inför att handla över gränserna. Många konsumenter känner en osäkerhet inför andra länders lagar och oroas över att skyddet mot ohederliga näringsidkare inte är det samma som i deras eget land. Denna osäkerhet undergräver den inre marknaden. För att motverka denna osäkerhet har EU antagit direktiv 2005/29/EG om otillbörliga affärsmetoder.

Separation av två klasser av åtta-dimensionella reella divisionsalgebror
This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).
Att spegla verkligheten - en studie av simuleringar i geografiundervisning på gymnasienivå
I arbetet görs ett försök att genom litteratur och elevintervjuer närma sig frågan om vilka förutsättningar för lärande som simuleringar i geografi erbjuder och vilka lärandeteorier som då blir relevanta. Intervjuer har därför gjorts med elever efter att de genomfört ett för undersökningen utvalt simuleringsspel. I arbetet ställs också frågan om hur elever uppfattar simuleringen som didaktiskt verktyg och ett antal svarskategorier struktureras. Slutsatserna är att lärandet i simuleringar i första hand tycks vara beroende av den egna praktiska erfarenheten, den sociala interaktionen mellan deltagarna och den emotionella laddningen. Elevernas uppfattningar av lärandeformen stödjer dessa kvalitéer, men tillfogade också betydelsen av variation i undervisningen och det inneboende spelrummets betydelse för kreativiteten..
