Daily rests of wild boar Sus scrofa sows in southern Sweden
For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.
Ekologi som kommersiell vara
Organic cotton has been in the medias field of vision for quite some time. This interestalso reflects in a growing awareness in the textile industry where more and morecompanies today offer organic cotton in their product range. With this in mind wequestion whether organic cotton has become a viable commercial product. We alsoacknowledge there is a lacking of understanding the complex problems that organiccotton manufacture involves, for example the huge effort and cost required for a transitionfrom conventional to organic cotton farming.The purpose of this paper was to study how textile, ecology and competition today arebeing combined by companies. We wanted with our investigation to find out whethercompanies in the textile industry use ecology as a competitive advantage.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Artificial sweeteners in beverage and their effecton hunger and energy intakeAuthor: Sofia Andersson and Sofia JakobssonSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2012BackgroundIn 2010 the total consumption of soft drinks in Sweden was estimated to 69 litres per person and17 % of the domestic production was estimated to consist of soft drinks sweetened with artificialsweeteners. The effects of artificial sweeteners on hunger is not yet fully understood. It isspeculated that they might increase hunger and hence increase energy intake.ObjectiveThe aim was to compile the evidence regarding the effects of an intake of a beverage sweetenedwith artificial sweeteners compared to sucrose on subsequent hunger and energy intake.Search strategyA systematic search for literature was performed in the databases PubMed and Scopus.Selection criteriaThe inclusion criteria were RCT, human studies, articles published in Swedish or English, studieson healthy adults and studies measuring hunger with a subjective scale or energy intake. Theexclusion criteria were studies who measured energy intake under other forms than standardisedor controlled, studies without a standardised dose of the beverage and articles needed to beordered against payment.Data collection and analysisFour articles were selected and examined according to a template developed by SBU. Theevidence for each outcome was weighed together and graded according to GRADE based on asummarised evidence form developed by the Sahlgrenska Academy.Main resultsAll four articles measured subjectively rated hunger.

Jämförelse mellan Theory of Mind-förmåga och pragmatisk förmåga hos svenska barn i 4 och 5 års ålder
Theory of mind involves the ability to take another person?s perspective in thought, emotions and intentions. There is today a lack of instruments to assess children?s development of Theory of Mind (ToM) in Swedish. ToM is considered by many scientists to be the basis for development of pragmatic competence. The relationship between these two abilities is complex and not fully resolved. Both abilities are important components for the development of social skills. The purpose of this study was to compare 4 and 5-year olds ToM-ability measured with a Swedish version of Wellman and Liu?s ToM-scale, Sally Anne and Social Emotional Test with estimated pragmatic competence measured with the Children?s Communication Checklist (CCC).
Sveaskogs möjligheter att utveckla trädbränsleverksamheten i Västerbotten och södra Norrland :
This final thesis is initiated by the wood fuel department at the Swedish forest company Sveaskog as part of a project which also involves two other final thesises. The overall goal of the project is to investigate Sveaskog´s possibilities to produce and sell different wood fuel assortments in Västerbotten and the southern parts of Norrland. The aim of this thesis is to investigate how much wood fuel Sveaskog can produce in the area during the next five years and what that would cost. Furthermore the thesis will investigate the total possible supply of wood fuel from all other possible producers in the area. Treated assortments are forest residues from final fellings, whole trees from direct wood fuel thinnings, non industrial wood and industrial by-products from sawmills.
The main effort to investigate Sveaskog´s production possibilities has been made to calculate the possible annual amount of forest residues and fuel from wood fuel thinnings that can be produced.
När jagar vargar vildsvin? : en utsikt för svenska förhållanden
Populationerna av både vildsvin (Sus scrofa) och varg (Canis lupus) ökar i Sverige. Då deras utbredningsområden först nyligen har börjat överlappa finns i det närmaste inga data på vargars predation på vildsvin i Sverige. Då detta är av intresse för den framtida debatten kring hur populationerna bör skötas, är syftet i denna studie att undersöka vargars predation och vildsvins beteende i Europa för att kunna dra paralleller till hur de två populationerna kan tänkas komma interagera i Sverige.
Att göra en studie kring ett rovdjurs val av byte är problematiskt eftersom så många variabler kan tänkas påverka, i kombination med mätmetoder som ofta inte är de mest exakta eftersom det handlar om vilda djur. I jämförelser mellan olika studier måste man dessutom väga in skillnader i val av metod och analys, så att komma med definitiva slutsatser i frågan är inte rimligt. Särskilt eftersom älg, som nuvarande är svenska vargars huvudsakliga föda, inte är så vanligt förekommande i Europa och jämförelser istället får utgå ifrån hur vildsvin föredras i förhållande till hjort.
Vargars diet skiljer sig vida mellan de studier från Europa som undersökts, även mellan relativt närbelägna områden.

ISO 14063 : drivkrafter och mervärden för miljökommunikation
The enterprises of today are beginning to realize that environmental issues are a important part of their activity. Companies and organizations are expected to a greater extent communicate their environmental work to the world surrounding them in a trustworthy and structured way. Lack of information or information that is incorrect may bring farreaching consequences. Communication is mentioned in several of the ISO 14001-standards. But what is missing is a guideline how companies should act to create and be sure of the quality of the data that can be used in the environmental communication.
