Förutsättningar för att utnyttja solceller i Sala-Heby relaterat till ekonomiska stöd

There have been several projects with solar installations in Sweden, and Sala-Heby Energi (SHE) wanted to create a solar plant. The question answered in this thesis is whether it is economically viable to create such a source of sustainable, renewable energy. The plant would be built with the help of the financial effort from 120 customers. This economic union would sell the electricity to the SHE, for SEK 4.50 per kWh up to a certain level over a period of 10 years. It would be a long term commitment to environmentally friendly electricity, using solar cells which convert sunlight directly into electricity.In year 2009 there was introduced a new state aid for photovoltaic systems, to create an increased and continuing interest in solar cells.

Välfärd hos växande nötkreatur ? finns den?

During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.

Skogsbruksplan-ett verktyg för att nå en skogsägares mål?

The aim of this study was to investigate which elements that functioned in a positive way on the natural behaviors of dairy cattle among KRAV certificated and conventional farms. The study was based on reading of earlier research and completed by interviews with farmers, animal health inspectors and consumers. The results showed us that the KRAV certificated farms used only loose housing barns and that the cattle were allowed a pasturetime of five months, or more, in one year. Our interviews with the consumers confirmed that KRAV was a well known trademark. The conventional farms were more flexible in their choice of housing systems, and used both loose housing barns and barns with the cattle tethered.

Linderödsgrisen : en inventering av populationsstruktur och produktionsnivå

In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

Djuretik i förskolan : Vilken vägledning ger läroplanen och hur arbetar förskollärare?

I syfte att undersöka om, och i så fall hur, förskollärare arbetar med djuretik som en värderingsfråga undersöks (1) förskollärares tolkning av läroplanens skrivning om ?respekt för allt levande?, (2) hur förskollärare arbetar med värderingsfrågan djuretik och (3) vilken hänsyn de tar till läroplanens krav på saklighet och allsidighet i detta arbete. Empirin bygger på kvalitativa intervjuer med sex förskollärare varav 3 är vegetarianer. Analysen baseras på poststrukturalistisk teori och teori om den dolda läroplanen. Informanterna anger att de arbetar med djuretik i ringa omfattning men visar också att förskollärarna förmedlar omedvetna budskap om djuretik.

Djurens påverkan på den äldreslivskvalitet : En systematisk litteraturstudie

Syfte: Syftet med denna systematiska litteraturstudie var att beskriva hur djur påverkade livskvalitet hos äldre. Metod: Artikelsökning utfördes via databaserna; CINAHL, SCOPUS och sökmotorn ELIN. För att artiklarna skulle få vara med i studien var kravet att de skulle vara publicerade mellan åren 2000 - 2010 och skrivna på engelska eller svenska. Sammanlagt ligger 14 vetenskapliga artiklar till grund för resultatet i denna systematiska litteraturstudie. Huvudresultat: Flertalet studier visade att Animal Assisted Activity (AAA) och Animal Assisted Therapy (AAT) främjade sociala interaktioner mellan äldre individer, lindrade känslor av ensamhet samt hade positiv effekt vid depression.

Hematologiska analysinstrument för mindre djurkliniker : en utvärdering av QBC-V och Scil Vet abc för analys av prover från hund och katt

Two haematological instruments intended for small animal clinic use were evaluated at the Department of Clinical Chemistry, Swedish University of Agricultural Sciences (SLU), Uppsala, Sweden. The QBC-V and Vet abc were compared to a reference instrument, the Cell-Dyn 3500. Fresh blood samples were obtained from canine and feline patients from the University Veterinary Hospital, SLU. The QBC-V was used for 111 canine samples and 78 canine blood samples were analysed with Vet abc. From cats, 23 samples were analysed with both instruments.

The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Svenskproducerat proteinfoder till slaktsvin

Soybean meal from South America is the most common protein feed used for animal production in Sweden. Production of soybean has negative effects on the environment and the transports from South America to Sweden causes considerable CO2 emissions. Therefore it is a growing interest in locally produced protein feed in Sweden. Protein feeds that are possible to grow in Sweden are rapeseed, peas, faba beans and lupins. Those are adapted to the Nordic climate and are perfect to grow in cereal rotations.

Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.

Sällskapsdjurs effekt på beteendeproblem hos äldre med demenssjukdom : En systematisk litteraturstudie

Syftet med studien var att studera hur sällskapsdjur kan påverka demenssjukas beteendeproblem och vara ett komplement till medicinsk behandling med lugnande läkemedel hos patienter med demens.Studien genomfördes som en systematisklitteraturstudie. Metoden författarna använde sig av var att de valde ut 9 stycken vetenskapliga artiklar från år 1999-2009 som hittats i olika databaser och referenslistor. Artiklarna analyserades genom att texten delades upp i de olika kategorierna lugnade effekt/oro, aggression, kontakt/beröring och läkemedelsanvändande. Resultatet visade att beteendeproblemen som aggression och oro, i flera av studierna blev bättre i sällskapsdjurs närvaro, men bara under den tiden som deltagarna fick animal assisted therapy (AAT). När deltagarna blev utan AAT försämrades deras beteendeproblem igen.
