Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.

Dietary fibre composition and sensory analysis of heat treated wheat and rye bran

When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values. The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).

Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :

Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

The awareness of the problem has grown rapidly for the last years in governments on international, national and regional level. The Swedish government is recognized as one of the leading countries in the climate and environmental work internationally. The Swedish municipalities play a big role in this successful work.

Laktester för riskbedömning av förorenad mark :

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

The biggest category was meat substitutes with 302 products and the second largest category was sandwich spreads with 150 different products. Within the remaining categories a varied number of products were found; 86 beverages, 64 cooking accessories, 34 milk free ice creams and 29 plant based yogurts. Of the meat substitutes were 28 only available for business clients.

Retention : Varför stanna när möjligheterna är oändliga

Bachelor thesis, Degree of master in Science and Economics, School of Business and Economics at Linnaeus University, Management, 2FE01E, Spring Semester 2013Author: Johanna Björklund, Sarah Gustafsson and Sofia NicklassonMentor: Anders HytterTitle: Retention: Why stay when your options are unlimited? Background: Employee turnover is a problem today, and companies face increasing challenges when it comes to retain employees within the organization, so called employee retention. This is a present concept and theory holds that more organizations realize that they need to put more focus on retention as one of their business goals to remain competitive. It?s important that organizations understand individuals' different needs and the factors that make them satisfied in their professional life.

Salmonellosis in Peruvian guinea pig production : a study to evaluate the prevalence of salmonella spp and importance of the disease

In Peru guinea pigs are raised for meat production and salmonellosis is considered as a major problem. Studies have detected salmonella in animals with enteritis and pneumonia. Salmonellosis exists both in an acute and a chronic form. In the rural areas the diagnosis is made according to clinical signs and macro pathological findings at autopsy. The major systems applied for the guinea pig production are often classified as family, family-commercial and commercial. These systems differ in number of animals and how industrialised they are.

Barnbibliotekariers förmedlingsarbete med lättläst barnlitteratur

The purpose for this Masters thesis is to describe childrens librarians work in supplying literature to children with emphasis on easy-reader materials. Our main questions are: · What do librarians believe characterizes an easy-reader book, and what do they base their decision on when classifying a book as easy-to-read? · How have the libraries in our study solved the hands-on difficulties associated with easy readers childrens literature? · Which factors do librarians consider to be important when supplying literature to children that are not used to reading or are not good readers? The theories we have used are Aidan Chambers Reading Circle and Karner Smidts view on the librarians professional roles when supplying literature. We have used a case study method, which means that we have gathered information through observation, objective papers and interviews. This has been done at six libraries.

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

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.

Picea mariana ((P. Mill.) B.P.S), P. abies (L.), Pinus contorta (Dougl.) och P. sylvestris (L.) : en jämförelse av produktion och potentiell kvalitet hos försöksbestånd i Jämtlands län

Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution. This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.
