Malaria drabbar över 200 miljoner människor årligen och är främst utbredd i Afrika. Många som drabbas är fattiga och har svårt att ha råd med botemedel. Malaria överförs genom bett från Anopheles myggor som blivit infekterade av parasiter från Plasmodium släktet. Den vanligaste parasiten heter Plasmodium falciparum och ger upphov till obehagliga febercykler. År 1972 påvisades förekomst av artemisinin i växten Artemisia annua.

Botanically diverse pastures are commonly used in New Zealand to reduce the ruminant environmental impact by reducing the methane production from the rumen digestion. In order to evaluate the effects diverse pasture species have on the milk fatty acid profile seventy-two lactating Friesian-Jersey crossbred dairy cows were used in a randomised block design with two replicates of six treatments. Six different pasture mixtures were fed at a daily allowance of approximately 15 kg DM/cow/day. The mixtures were categorised as either a simple or a diverse pasture. The simple mixtures all contained white clover with the addition of either a standard diploid perennial ryegrass (RG), a diploid high sugar ryegrass (HS) or tall fescue (TF).

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

Denna uppsats behandlar homosexuella hatbrottsoffer och hur homosexualitet formuleras i artiklar i två av Sveriges största tidningar med dagsutgivning: Aftonbladet och Dagens Nyheter. De analyserade artiklarna är hämtade från 1 januari 2003 fram till 1 maj 2010 då analysen påbörjades. Anledningen till att urvalet hämtades från 1 januari 2003 är att hatbrottslagen från och med då även gällde brott mot personer på grund av sexuell läggning. Uppsatsen sökte svar på hur viktigt sexualiteten är för hatbrottsoffren och hur hatbrottsoffrens presenteras i artiklar om hatbrott från ovan nämnda tidningar.Uppsatsen utgår från vad som gör det perfekta mediala offret och vilka kriterier ett offer och ett brott bör uppfylla för att vara idealt för rapportering. Yvonne Jewkes (2004) och Ester Pollack (2000) har båda tittat på vad som är det perfekta brottet för att rapportera om det.

There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

The aim of this study was to investigate if the botanical composition of haylage affects pH, dry matter content and microbial composition of the faeces in horse and pig and ileal environment in pigs. Two separate studies were conducted where pigs and horses were fed two diets containing haylages with different botanical composition. The first haylage was from a tilled land dominated by timothy and meadow fescue and the other haylage came from a meadowland with a large inclusion of dandelion, 25 % and common couch. The dry matter content (70.8 % and 73.0 % respectively) and the pH-value (5.7) were similar in both feeds. The first study was made as a three-periods switch-back study with 7 Standardbred horses. In the first and the third period, 7 and 9 days long respectively, the diet consisted of the haylage from the tilled land, oats, sugar beet pulp, soy bean oil meal, lucerne pellets and brewers yeast.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Title: How to Construct the Perfect Scandal ? a study of the news reported by Expressen concerning the SD-scandalAuthor: Linnea IvarssonThis C-paper presents the incident concerning the political party Sverigedemokraterna in Expressen in November 2012. The newspaper was the main source of the news reporting with the mobile phone camera film from the occurance and led the way of the news reporting in Sweden about three party members.The paper investigates how the story telling of the so called SD-scandal was constructed, using Critical Discourse Analysis as the analysis method combined with selected parts from the analysis method of critical linguistics. The theories that have been used to establish the results of the analysis are Critical Discourse as a theory based on Norman Fairclough and Teun A. van Dijks theoretical keystones combined with Sigurd Allerns and Ester Pollacks theories and schematic point of view on the constructions of political scandals in media.With the theories and analysis methods above mentioned the results turned out to confirm the theory about how political scandals in media are constructed and designed with certain strategies and agenda.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops. The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Titel: Identitetsskapande hos unga kvinnor genom sociala medier - med välbefinnandet i fokusFörfattare: Ester FardellKurs: Masteruppsats inom medie- och kommunikationsvetenskapTermin: Vårterminen 2013Handledare: Annika BergströmAntal ord: 19 897ABSTRACTDenna studie undersöker vad unga kvinnor har för uppfattningar om identitetsskapande i sociala medier och om de anser att det påverkar deras psykiskavälbefinnande. Forskningsfrågorna avser att etablera hur unga kvinnor generellt ser på användningen av sociala medier, följt av vad de har för uppfattningar kring hur unga kvinnor skapar sig identitet(er) via sociala medier. Slutligen undersöker studien om deanser att identitetsskapande genom sociala medier har någon koppling till deras välbefinnande. Studien behandlar olika infallsvinklar där påverkansfaktorer isamhället, generella teorier kring socialt umgänge utanför och i sociala medier och hur det är att vara ung kvinna idag från ett feministiskt perspektiv i samband med kärnbegreppen för studien: Sociala medier, identitetsskapande och välbefinnande.Sociala medier klassas i denna uppsats utefter Nordicoms definition där sociala nätverk, communities, chattgrupper/diskussionsforum och bloggar ingår. En av de grundläggande teorier som har använts som utgångspunkt för identitetsbegreppet är Eriksons teori om identitet som en process där både tillhörighet och differentiering till andra människor är viktigt.
