Restaurerade ängs- och betesmarker : restaureringseffekten på växter och insekter
Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants.
By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.
Undersökning av global epigenetisk metyleringsstatus hos juvertumörer på hund :
Mammary tumors are the most frequent type of tumors in bitches in Sweden. Many
studies have been published concerning mammary tumors, but there is still much to
be learned about this disease.
One has, since some time ago, had the knowledge that addition to or removal of
methyl groups to genes can inhibit or activate gene-expression. Methylation and
demethylation is a normal phenomenon in the body and it is essential for the
development and survival of the individual. The risk of developing a tumor disease is
increased if the global methylationstatus is changed; if oncogenes demethylates
(activates) or if tumor suppressor genes methylates (inactivates). In the human
medicine one has seen that there are differences in methylationstatus between
different tumors.
In this study tumor and normal tissue from ten dogs were examined with regard to
methylationstatus.
Kreditbedömningen av mikroföretag : Kreditbedömningens faktorer och påföljden av den slopade revisionsplikten
Introduction: 1 November 2010 came the amendment about the audit requirement into force. The amendment concerned only micro-enterprises. The most common form offinancing for micro-enterprises are bank loans, therefore the banks play a major role in the business and wellness of micro-enterprises.Purpose: Purpose of this paper is to examine if the credit assessment has been affected by the removal of the audit requirement for micro-enterprises.Method: This study will be conducted by a qualitative study in the form of interviews. Five interviews were conducted, with four respondents from the large banks and one respondent from Almi Företagspartner.Conclusion: All respondents agreed that the audit is seen as a mark of quality, some lenders will continue to request it from the micro-enterprise while other lenders look at other factors such as ownership, relationship or business concept..
Sökarkyrkan; Marknadsförd religion mot den postmoderna sökaren? -Hur och varför ett fåtal innovativa religionsproducenter förändrar det amerikanska religiösa landskapet
The controversial phenomenon of ?seeker-oriented? megachurches are currently transforming the American religious landscape. These churches, some housing up to 30,000 worshippers every week, are targeting religious seekers as their primary objective. Their success in attracting and converting those who usually wouldn?t even think of attending church can in large parts be explained by changes in liturgy, the removal of visible theological discussion and use of shopping mall styled buildings, designed to make the religious seeker feel like home.

Studie på beteendeförändringar hos katt efter behandling av Feline Odontoclastic Resorptive Lesion (FORL) :
Feline odontoclastic resorptive lesion (FORL) is a tooth disease
affecting both domestic and wild cats. Although FORL was
described as early as the 1920´s, the etiology is still unclear. Several
hypotheses have been presented but different studies have obtained
contradictory results, and today there is no generally accepted
etiology. Teeth affected by FORL are characterized by root
resorption with progressive destruction of the tooth structure and
alveolar bone as a consequence of clast cell activity. The disease is
considered very painful when reaching a certain stage.
Ipsilateralt vaskulariserat ulna autograft vid behandling av osteosarkom i distala radius hos hund : en fallstudie
Limb-sparing surgery aims to provide a functional pain free leg for the patient after removal of a local tumour in the leg. Reasons to perform limb-sparing instead of amputation can be arthrosis or hipdysplasia or other problems with the locomotor apparatus that makes the patient unsuitable for amputataion. Owner reluctance to amputate is another reason for limb-sparing.
This master?s thesis is a case study of a dog with an osteosarcoma in its distal radius. The dog was treated by a limb-sparing method that uses the ipsilateral ulna as a vascularized roll-over autograft.
Det är ett sätt att växa att känna sitt eget värde, att man faktiskt är värd något : En kvalitativ studie om familjehemmens uplevelser av uppdraget
The purpose of this study was to gain knowledge and a picture of how foster parents perceive their task, the role of the placed children and their biological parents. Even how they perceived their family have been affected by the mandates removal. Consistently showed the most positive experiences with strong ties to the children placed. However, there are experiences of the need for additional guidance, support, education and contact with the client to enhance a sense of competence in the task and prevent collapse. Burnout experienced often based in the placed child's difficulties in integration.

Biblioteken och censuren: om försök att censurera HBT- litteratur på amerikanska folkbibliotek
The aim of this study is to look at censorship and attempted censorship of books about gay, lesbian, bisexual and transsexual (GLBT) people in public libraries in the USA. People from the public can submit formal challenges to a book at the library when they find the material offensive which can lead to those books being taken away from the library shelves. The questions asked are why GLBT- literature is being challenged, and sometimes banned, and how do the libraries deal with the challenges to the books.It is nowadays the people from the public, rather than the government or the librarians that are behind many cases of removal of books with homosexual themes. The study presents some of the fictional GLBT- literature that has been cause for much controversy in the USA. All the five examples mentioned are children?s books concerning GLBT- themes and are among the most challenged books in American libraries in the past twenty years.
Solenergi och värmelagring i kvarteret Lagern
Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.
Improvements in milking management through imitation of calf behaviour
Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.
Interferences during analysis of polyphenols in fruit juices
One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.
