Effekter av landskapets sammansättning på humlearters förekomst
The species in the genus bumblebees (Bombus) are important pollinators. In the world there are 250 bumblebee species and there are 34 species in Norway. The purpose of this study is 1) to assess changes in the species composition of bumblebees in twenty different places in Norway that have been inventoried first one time between 1939-1960 and the second time in 2012, and 2) to relate species richness and distributions to current landscape composition with the aid of orthophotos. In this study, I have used regression analyzes on the different bumblebee species that were present or absent at the inventory, using the premises of the following variables: low or high altitude, latitude, longitude and seven different types of land use (farmland, building/plots, open land/pasture, forest, wetland and open or snow-covered ground above the tree line) to see if there was any relationship between each species and the different variables.
I have not analyzed what the landscape looked like at the first inventories and therefore we cannot say whether it has changed and if that is why species number has decreased. This would be interesting to study further and to see if there is any relationship between landscape changes and bumblebee?s species decline.
Oralt intag av grönt te och dess effekt på uppkomsten av UV-inducerad hudrodnad, erythema solare ? En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.
Affektmedvetenhet och stress : En sambandsstudie utifrån en integrerad stressmodell med affektsystemet som brygga mellan psyke och soma
A unified model of stress and affect consciousness was proposed. The connection between affect consciousness and perceived stress was studied. Teachers (n = 19) were interviewed using Monsens affect interview, followed one month later by a questionnaire containing Perceived Stress Scale (PSS), State-Trait Anxiety Inventory (STAI-S, STAI-T) and Twenty Item Toronto Alexithymia Scale (TAS-20).Statistical analysis showed no connections between level of total affect consciousness and perceived stress. Though there were some indications of a negative relationship between affect consciousness and trait anxiety. There were also indications, using a complementary analysis, of a connection between level of affect consciousness on the subscale distress in the interview and perceived stress.

FN och internationella administrationer
This paper's purpose is to examine the mandate and the role of the UN as an administrative actor. Today, we often see post-conflict territories in the need of governance. In the absence of local supported government the UN has the ability to fill that void. The paper will look at two actual examples where the UN has assumed the role as administrator; West Papua and East Timor. I will conduct the research by using books and scientific articles from journals..
"Man slutar tänka, man rycks med i någon slags gruppsykos" : En diskursanalys av massmedias diskussion kring våldtäkten i Bjästa 2009
The aim of this thesis is to analyze the media discussions of the rape in Bjästa 2009 and to reveal how stereotypical illusions of ethnicity, religion and gender affect how media understands and defines violence. The rape in Bjästa occurred in a ?Swedish context? but has been defined as honor related in other arenas outside media. This discussion occurred because the whole village turned against the woman that was raped and supported the perpetrator? a phenomena that speaks against the idea of an equal society and a behavior that is usually understood as honor related and something that the ?others? do.

Biologin hos svenska Lilioceris arter och åtgärder för att begränsa deras skadeverkningar :
Summary
The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years.
The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies.
Lilioceris species overwinter normally as pupae in the soil under the host or close by.
Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining.
My own observations include different treatments of both lily foliage and of the leaf beetle.

BCAA-supplementering i samband med levercancerkirurgi
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: BCAA supplementation in patients undergoing resection for liver cancerAuthor: Mikael Semaan and Viktor SjölingSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013BackgroundLiver cancer is the fifth most common cancer worldwide and the third largest to cause death. Protein-energy malnutrition is common in patients with liver disease and they often suffer from changes in the hepatic metabolism of nutrients and other substances. There is a basis for recommending BCAA supplementation in other certain liver diseases. Given the similar clinical picture of liver cancer surgery, it is possible that supplementation of BCAA can be beneficial for these patients as well.ObjectiveThe aim was to study the scientific basis for the effect of branched chain amino acid (BCAA) supplementation in liver cancer patients. Can it improve their recovery in terms of nutritional status and albumin levels, and does it changes the duration of hospital stay, after surgery?Search strategyFive extensive searches were performed on PubMed and Cochrane after appropriate study material.

De Svenska dagstidningarna och dess relation till de Svenska emigranterna till Amerika mellan 1901-1904 : -En argumentationsanalys om Svenska dagstidningars åsikter om den svenska emigrationen, med inslag av nationalism.
The Swedish emigrants, in 1901-1904, were displeased with their home country, so they moved to America with hope to find a better life. Even though they were displeased they still had a great love for their home country and tried to either create a ?new Sweden? (the Swedish-Americans), or they traveled back to their families, hopefully with savings big enough to buy their own home. Sweden did not have a homestead act like the Americans did, which probably is the biggest reason to the emigration. There was also the question of each individual?s right to vote.
