Svenska sojabönor - finns marknadsmöjligheter?
The large-scale soy cultivation has negative consequences for the habitat of local Populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.
Varför förekommer rörliga ersättningar i det svenska corporate governance-systemet? : En undersökning av olika teoretiska perspektiv
Enligt det agentteoretiska synsättet kan osäkerhet kring företagsledarens beteende avhjälpas genom att förutsätta ett opportunistiskt beteende från denne och sedan utforma styrmekanismer som begränsar denna opportunism. Agentteorin har dock sitt ursprung i en amerikansk kontext med helt andra värderingar än de som format de svenska institutionerna. Därmed öppnas det för andra orsaker och teorier som kan förklara förekomsten av rörliga ersättningar i Sverige.Syftet med denna uppsats är att bidra till diskussionen om vilket eller vilka teoretiska perspektiv som kan ligga bakom förekomsten av belöningssystem i Sverige.Uppsatsen bygger på kvantitativ forskningsstrategi detta eftersom författarna försöker finna ett samband mellan olika variabler. Genom att utgå från en total Populations undersökning av ca 300 börsnoterade företag kom den slutliga populationen som uppfyllde de uppställda kriterierna att uppgå till 211 företag. Respektive bolags årsredovisningar studerades därefter med hjälp av ett kodningsschema som angav informationen som skulle inhämtas och kvantifieras. Information har sedan statistiskt bearbetats för att kunna bidra till att testa de uppställda hypoteserna.Eftersom att ingen av agentteorins antagande som prövades kunde styrkas indikerar detta att andra teorier kan vara bättre lämpade. Resultaten indikerar på att det är institutionell teori i form av härmande isomorfism och symbolisk kompensation som är mer tillämplig för att förklara rörliga ersättningar i det svenska corporate governance-systemet.
Improvement in agricultural production in a rural area of Cambodia between 2004 and 2011 - with an emphasis on small scale cattle production
Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the Populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.
Finns det något samband mellan stormusslors (unionoida) föryngring och utsläpp i närheten av dess levnadsmiljö? : en jämförelse mellan vattendrag i Västra Götaland
Common species of freshwater mussels may, like the freshwater pearl mussel (Margaritifera margaritifera) have a drastic decline in number and there is several reasons, like sedimentation, a decline of host fishes, introduction of alien species, nutrition leakages from agriculture and pollutants of medic drugs and poison. Ann Gustavsson made in the year of 2007 a study over rejuventation of freshwater great mussels in nine watersystems and considered that the rejuventation within the Populations were all along the line poor. This study orients from her work and points to determine if there is a connection between the poor juventation and pollution of nitrogen and phosphorous from industries and private sanitations. The study was performed with the software program ArcGIS9.2 to take out drainage areas for the concerned habitats and contact was made with the concerned authoritys. When it comes to supervision of private sanitations is it the countys and for industries is it the county administrative board.
Är den starkt växande vildsvinspopulationen ett hot mot tjäderns reden?
This case study is based on a previous documented method of manufacturing artificial nest containing pre-colored hen eggs. This method is going to be used to find, if the wild boar population, which is growing in number, is a threat to the capercaillie population. In comparison to the wild boar population, the capercaillie population is diminishing in different parts of Sweden. In order to find out if they are affect by each other, the case study was carried out during the months of April to May 2009. 100 artificial nests were placed out on various locations on the Södertuna estate just in the outskirts of Gnesta. The unique aspect of this study is that a fenced environment to keep out wild animals is used to conduct this study, which has been previously known to be free from wild boar, but the area outside has sittings of wild boar. So to fully understand how this affects the capercaillie population, 50 of the nests were placed outside the fence area, while the other 50 nests were placed inside the fenced area. The sites were visited on two separate occasions, and were noted of the changes inside and outside the fenced compounds.
Effekter av två olika hösilagefoderstater på tarmfloran och träcksammansättningen hos häst och gris :
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.

Reproductive physiology of the female cat
The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms
behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat Populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on
ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed.
The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with
copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

Enkät för skattning av 8-åriga barns fysiska aktivitet : En valideringsstudie. Frågor ur SIH-enkäten jämförda med referensmetoden accelerometri
AimTo validate the STOPP-8-questionnaire (S8Q), containing items from the SIH-questionnaire, against the criterion method accelerometry to estimate its capacity to assess 8 year old Swedish children?s physical activity (PA). Can it assess children?s physical activity? Can it differentiate the active children from the sedentary? If the answer is yes, how well can it do so? MethodData was collected during fall and winter the school year of 2008 - 2009 via the project STOPP-8. Out of 676 children at 12 schools in Stockholm area, 155 (boys n=72, girls n=83) provided complete questionnaire data and wore an accelerometer (Actiwatch 4) during 7 consecutive days which provided data for mean and median activity, time spent sedentary, in moderate to vigorous PA and vigorous PA.
Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar
Around the world, forests are generally being fragmented and as plant Populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.
