Skogseldens påverkan på epifytiska trädlavar på tall i relation till brandintensiteten :
Not much is today known about how epiphytic lichens are effected by fire. A considerable part of the fires in Sweden today are prescribed fires for the purpose of environmental conservation. How these fires affect lichens is largely unknown. The aim of this study is to find out how epiphytic fruticose and foliose lichens on Scots pine are affected by fire, and to elucidate the relationship between fire intensity and the survival of lichens and later re-colonization.
The study was performed at three locations just outside Umeå in Västerbotten that were burned 5-7 years earlier. In all locations there were larger groups of surviving Scots pines with varying amount of fire-damage in the crown, which enabled a reconstruction of fire intensity.
Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :
Protecting the environment has with time grown to take a more central role in the society.
Agriculture plays an important role in the society since this sector produces our food. More
thorough research on how agriculture affects the environment is therefore motivated. This
research can be used to improve the agricultural practice from an environmental point of view.
This is something that both the farmers and the consumers can profit from.
This study aims to form the basis for creating environmental indicators for use of nitrogen and
energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about
their farms, both organic and conventional. They produce milk with different intensity, defined
as the amount of milk delivered (sold) per hectare of arable land.

Kronisk mitralisinsufficiens hos hund : samband mellan graden av klaffinsufficiens och det arteriella blodtrycket
Myxomatous mitral valve disease is a common disease in older dogs of small- to medium-size breeds. The mitral valve, and less commonly the tricuspid valve may be affected which causes them to leak blood from the ventricle to the atrium of the heart during systole. With increasing severity of mitral valve leakage the forward stroke volume ejected into the aorta decreases, which may lead to an increase in blood pressure in the pulmonary vein resulting in pulmonary edema. A decrease in cardiac output may lead to a decrease in blood pressure, but the body may respond in order to normalize the blood pressure. Franzén showed in 2007 that the systolic blood pressure was increased in dogs with severe mitral insufficiency.

Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.
An image-based method for identification of new inhibitors of Signal Transducer Activator of Transcription 1
Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.
Hetare med HIIT eller lite mer av LIT?
Bakgrund: Högintensiv intervall träning (HIIT) har i tidigare studier visat sig vara mer effektiv för att öka den maximala syreupptagningsförmågan (VO2Max) än lågintensivträning. Det finns få studier som undersökt sådana anaeroba intervaller som kombinerar maximal sprintning med efterföljande högfart och slutligen gång i normal takt. Syftet med denna studie är därför att undersöka vilken av löpningsmetoderna högintensiv intervall träning och lågintensiv träning ger mest ökad maximal syreupptagningsförmåga samt bäst aerob och anaerob prestationsförbättring.Metod: 9 män och kvinnor valde att frivilligt delta i studien och delades in i antingen en högintensiv eller lågintensiv grupp. Testerna bestod av ett Åstrandtest, 2,5 km löpning och 30m sprint. HIIT gruppens intervaller kallades 20:55:20 då deltagarna först sprang 20 sekunder maximal fart, sedan 55 sekunder i hög fart för att slutligen gå i 20 sekunder.
The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows
Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Fysisk träning som hjärtrehabilitering efter en myokardieinfarkt: en litteraturstudie
Background: Myocardial infarction is the most common individual disease among people in the west world. In Sweden there are over 50 000 women and men who get myocardial infarction every year and about 40 % of them dies. Exercise training is one part of cardiac rehabilitation and since 1980 Sweden use the guidelines from that time. Aim: The aim was to review exercise-training modalities in cardiac rehabilitation after myocardial infarction and the physiologic- and psychological effects. Method: Facts were obtained by searching through the database PubMed for articles published from 1994 and ten years forward.
The Value of Relationships in a Chinese-Western Business-to-Business Context: An Investigation on Relationship Bonds, Adaptation, Trust and Commitment
The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.
Influence of the habitat on the potential for cannibalism and population dynamics in stream-dwelling European grayling (Thymallus thymallus L.)
Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).
Den villkorliga självkänslans relation till self-efficacy
A self-esteem that is contingent on affirmation from others leaves the individual psychologically vulnerable. Ccontingent self-esteem has been shown to be either relationship or competence based. The aim of the current study was to examine the relationship between relationship based self-esteem, competence based self-esteem, the under dimensions of those, and self-efficacy. Questionnaires were handed out to 69 university students. The results indicated that competence based self-esteem predicted a significantly low self-efficacy.
Svampar associerade med raps : betydelse för uppkomst och grödetablering
Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems.
This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens.
The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.
