Krishantering i förskolan

Detta examensarbete visar att upplösande av samägande av fast egendom är viktigt då ägandet av fast egendom är kopplat till rättigheter såväl som skyldigheter. Det är av mycket stor vikt att ägande och brukande av skogsfastigheter fungerar och att det finns förutsättningar för att lyckas med det. Dock kan samägandet i vissa situationer hindra utvecklingen av fastigheten. Skogsbruket är en viktig inkomstkälla för den private skogsägaren såväl som för Sverige, skogsbruket i vårt land stod 2010 för 7 % av världens totala export. Även om Sverige är ett litet land i världen, är det inte obetydligt inom skogsbranschen.

Uptake of 137Cs by fungi and plants due to potassiumfertilization in Heby municipality in response to theChernobyl nuclear accident

The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodineand strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflifeof about 30 years and is therefore one of few radio-fission products remaining inmeasurable quantities in the Swedish soil. Radiocaesium behaves similarly to potassium insoil-plant systems and is easily absorbed by plants. It is important to understand how 137Csbehaves in different ecosystems in order to minimize the risk toward humans.The aim of this study was to determine how potassium fertilization influences radiocaesiumcontent in different forest plants and fungi. Potassium fertilizer was spread once in 1992 withapproximately 200 kg KCl per ha.

Födosammansättning hos gråsäl (Halichoerus grypus) samt test av flotte för insamling av sälfekalier.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Min syster är särskild -upplevelser av att växa upp med ett syskon som har ett funktionshinder

AbstractGrowing up with a functionally disabled sibling can bring joy and positive experiences, but also complications. The purpose of this paper is to describe the experience of growing up with a functionally disabled sibling. I have chosen to focus the examination on how individuals with functionally disabled siblings believe they have been affected by their relationship to their functional disabled sibling and whether it has continued to affect them in adulthood.The examination was qualitative and conducted through interviews. The results showed that siblings of functionally disabled individuals tend to grow up with strong feelings of responsibility and anxiety that continue to affect them into adulthood. The investigation further showed that all interviewed chose occupations in care, and that they give great attention to relationships to others.

Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige

Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.

M2M - affecting organisations, offerings and relations

Machine-to-machine (M2M) communication is a phase in the digital revolution connecting computing devices with each other bringing along new business opportunities for companies. Although being a fast growing field it has not been researched to any greater extent, particularly not within the academical literature. Consequently, information on how M2M can affect organisations seems strongly needed. This thesis uses three perspectives, derived from already recognised business benefits of M2M, as an aid to select proper theoretical tools to investigate the phenomenon. The purpose of this thesis is to gain knowledge of how an M2M adoption affects a firm?s organisation, customer offerings and customer relations.

Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri

Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.

Könsselektering av spermier från lantbrukets husdjur

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

Elektroniska tidskrifter - var, när, hur och i så fall varför?

An increasing number of scholarly publishers are beginning to make their journals available electronically. At the same time there is a growing amount of exclusively electronic journals freely accessible on the Internet. These are facts that librarians have to take into consideration.This master's thesis aims to describe the electronic journal and its role in Swedish academic libraries. In a review of current literature about electronic journals, the authors discuss their strengths and weaknesses, and their impact on scholars, publishers and libraries. To investigate the situation in Sweden, a questionnaire was sent out to 43 academic libraries.Questions were raised about the selection and acquisition of electronic journals, access, technology and economy.The results show that almost half of the 35 responding libraries offer electronic journals to their users.

Utvärdering av stödgruppsverksamhet för barn och ungdomar som växer upp riskmiljöer

ABSTRACTBackground: Children and adolescents growing up in families where parents have serious problems are exposed to an increased risk of developing poor mental or physical health themselves. In a support group work they can meet other children in the same situation, receive help and support to process their emotions and manage their everyday life.Aim: To investigate if support group work at Trappan can reduce the psychological problems load and increase the experience of life quality, hopefulness and optimism in children and adolescents growing up in families where either addiction or mental illness occur in one of the parents. The purpose was also to investigate if there was any difference between these both child groups regarding psychological problems load, experience of life quality, hopefulness and optimism before and after support group participation.Method: Questionnaire study on children and adolescents of parents with addiction or mental illness. The children participated in support group work at Trappan. The measuring?s were conducted before and after support group participation.Results: In both groups an increased life quality in connection to finished support group participation was observed.

Predation på evertebrater under tidig vår i sjön Tåkern

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Bildandet av naturreservat : uppföljning och klimatanpassning

AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined  how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.

Vilken preferens har tjockskalig målarmussla (Unio crassus) för bottensubstrat och vattenhastighet i Storån, Östergötland?

The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

Healthier vegetables through temperature stress? : a review of Brassica oleracea

The objective of this report is to present a review of the studies which has been carried out up to days date concerning how temperature affects vegetables physiologically when it comes to their health inducing as well as quality reducing features. The essay therefore starts off with defining what is meant by the terms health promoting and quality reducing features. It then moves on to describe how different subspecies of Brassica oleracea, that is to say vegetables such as broccoli, cauliflower, Brussels sprouts and kale, is affected by temperature. B. oleracea was chosen because the species contains several commercially interesting subspecies and therefore provides a broad field even though only one species is assessed.

Köparens undersökningsplikt respektive säljarens upplysningsplikt vid köp av fast egendom

Syftet med uppsatsen var beskriva säljarens upplysningsplikt respektive köparens undersökningsplikt vid köp av fast egendom, samt att beskriva konsekvenserna då upplysningsplikten respektive undersökningsplikten inte iakttas. För att förtydliga detta ytterligare har vi även valt att behandla fastighetsmäklarens och besiktningsmannens ställning vid köp av fast egendom. Vi har valt att använda rättsdogmatisk metod, vilket innebär att beskriva nu gällande rätt. Enligt JB ligger det på köparens ansvar att göra en noggrann undersökning av byggnaden. De fel eller skador som köparen har haft möjlighet att upptäcka kan inte säljaren göras ansvarig för.
