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.
Exosomes as a potential mechanism of intercellular spread of prion protein
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Respiratorisk sinusarytmi under påverkan av emotionell stimuli: en studie av emotionell påverkan från biologiska och ickebiologiska hotrelaterade bilder.
In this paper respiratory sinus arrhythmia (RSA) was examined in relation to two kinds of threatening pictures, biological and nonbiological. Based on the results of prior research the hypothesis was claimed to note a difference between the two types of pictures regarding RSA and gender differences regarding cardiac activity due to the emotional stimulus. ECG and respiration were collected from 36 adults, 17 women and 19 men. There were no significant relationship between the different types of threatening pictorial stimuli, and no significant effects of gender were found. The results support some of the prior research on the topic but are in conflict with other.
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.
Effekter av kalavverkning på mindre boreala sjöars vattenkvalitet
Forestry is an important industry in Sweden, with clear-cut as the most commonly used method for harvesting. Here the long-term impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. Data for additional 15 lakes sampled for the Swedish monitoring program were also used. Lakes were classified as 5, 25, 40 and 60 year based on data of the forest age in the catchment, gathered from the Swedish national forest inventory. Clear-cut lakes were classified as 5 years (>20% of the catchment clear-cut during the last 10 years).
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.
Analytisk dimensionering av räddningstjänsten i Skåne Nordväst
This report is a part of the process of enhanced cooperation between fire rescue services in the region of North West Scania. The aim of the report is to study and analyze how the fire rescue service should be structured, in terms of rescue units and personnel, if no account is to be taking to the current organization. Two types of accident are considered in the report, traffic accidents and building fires. These are more affected by decreased response time than other accidents. Several suggested organizations are presented and they are evaluated with the computer program REP.
Afasi-vänlig information : inför funktionell undersökning av språk med magnetresonanstomografi (fMRI)
Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.
Revision av gränsvärdena - En studie om hur svenska revisions- och redovisningsbyråer skulle påverkas av tillämpning av EU-direktivens maximala gränsvärden för revisionsundantag
Background: Currently Sweden has the possibility to like other EU countries raise the limits of statutory audit, but have chosen significantly lower limits. The reform was adopted in 2010 and only applies to smaller companies and there is great pressure for the limits to rise in future. This would enable Swedish companies to compete on equal terms in Europe. Aim: The aim of our study is to investigate the impact of the removal of the statutory audit for smaller companies from audit and accounting bureaus perspective and also the possible impact if the limits were to rise. Furthermore we want to explore how the supplies of other financial services have developed as a result of this.
Fonologisk medvetenhet i förskoleklass : En interventionsstudie
International studies show that literacy skills have deteriorated among Swedish students. Empirical evidence states that before being able to learn to read it is important to have phonological awareness. From this perspective, an intervention study was launched to examine whether pupils´ phonological awareness could be enhanced through the work of a special model during a limited time. The aim of the study is to investigate whether six pupils in preschool develop phonological awareness based on Bornholmsmodellen during a limited period of time. The control group was made up of the remaining pupils in the preschool class.
Surgical stress response in dogs diagnosed with pyometra undergoing ovariohysterectomy
The aim of this study was to investigate the intraoperative surgical stress response in dogs undergoing ovariohysterectomy and to compare acepromazine and medetomidine as premedications. 15 dogs diagnosed with pyometra were used in this study. Blood pressure and heart rate were used as parameters to measure surgical stress response. The surgery was divided into four phases. Phase 0 was the period 10 minutes before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, ligation and transection of mesovarium and phase 3 was ligation of cervix, removal of organs and closing the abdomen.
The results showed that phase 2 was the most intense phase of surgical stress, regardless of which premedication the dogs received.
When acepromazine and medetomidine were compared the results showed that within phase 3, all dogs that were given medetomidine had higher blood pressure compared to dogs that were given acepromazine.
The dogs that were given acepromazine had higher heart rate than the dogs that were given medetomidine in phase 0, phase 2 and phase 3.

ACTa våra stressade lärare: en randomiserad studie om Acceptance & Commitment Therapy (ACT) för stressade lärare
The present study examines the effect of a nine-hour Acceptance and Commitment Training (ACT) intervention for teachers who experience stress. Twenty-two teachers from four different counties in southern Sweden were randomly allocated to an ACT intervention (n=15) and a control group (n=7). The ACT condition received three three-hour sessions of ACT over a six-week period, and the control group received a three-hour stress lecture at one occasion. At a follow-up four-weeks after completed intervention, ACT participants showed significant in-group differences on stress, psychological flexibility, general health, and burnout. At a between group comparison, only psychological flexibility was significantly enhanced at the follow-up.
Estimation av bostadsrättspriser i Stockholms innerstad medelst multipel regressionsanalys.
This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.
Plafondmålningar - Arkitektförbundet Måleri på duk, Skadefenomen och åtgärdsproblematik
The concept of large paintings includes panoramas, cycloramas and other paintings thatin size exceeds the normal magnitude of wall hung paintings. When these large paintingsare mounted in the ceiling, they are referred to as plafonds. When they are performedon canvas, certain kinds of structural distortions and stress occurs. In addition, becauseof their size and mounting high up in the ceiling, plafond paintings are often difficult tohandle, which leads to less or no maintenance. A plafond may therefore be left withoutattendance for many decades.This thesis has its focus on what happens with plafond paintings on canvas when they areexposed to gravitational forces, and the problems involved in restoring large paintingsmounted in the ceiling.
Ytterväggar och bjälklag för flerbostadshus
The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.
