Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

Background: Intimate partner violence (IPV) is a large public health problem that foremost affects both women and children, nationally and globally. Several accessible reports about IPV and education for staff that in their occupation can meet battered people shows the importance of increased education for several occupational groups to decrease the large number of unrecorded cases.Purpose: The study explored how six occupational groups, in the municipality of Kungälv, related to IPV in their professions, were influenced by whether they had education in IPV or not.Method: We chose a quantitative approach, a cross sectional study. A questionnaire was constructed and handed out to 156 participations. The occupational groups were a section in a hospital, the police, the home care services, an elementary school, a pre-school and the public dental care. The answer frequency was 86 %.

The purpose of this report is to make an evaluation of the self-monitoring for scarification which Stora Enso is using and this study deals with the effects and importance of scarification. A comparison is made in this study with the purpose to highlight any differences between some of the leading forestry companies and significant forest organizations in Sweden. The companies represented in this report are Korsnäs, Mellanskog, SCA, Sveaskog and Södra. In the beginning of this study an interview form was set up together with Daniel Forsberg at Stora Enso. Stora Enso is the head object of this report and seven interviews were made within that company. At the other companies only three interviews were made within each one, with an exception to Mellanskog who wished four.

To ensure that animals are treated well and kept in environments fitted for them, Sweden has animal welfare legislation. One of the requirements in the legislation is that horses are kept in spaces that has a ceiling height that measures at least 1,5 * the height at the withers of the horse, but always a minimum of 2,2 m. But a minor derivation can be accepted from these measurements if certain criteria are fulfilled. If the ceiling height is to low the ventilation in the stable can be negatively affected. It can also affect the posture of the horse and may increase the risk of the horse being injured.

During the period after the Second World War Sweden underwent a quick transformation due to a strong economic development. Decades-long rule for the Social Democratic Party now led to the creation, in Sweden, of a modern welfare state. This period in Swedish history is often considered to be the time when ?the Swedish model? was formed. Tage Lindbom (1909?2001) was a historian and intellectual in the Swedish labor movement.

This paper is a critical evaluation of the Swedish system with special mediation. The district court has the opportunity, in cases that are amenable to out-of-court settlements, to refer the dispute to special mediation. However, this is extremely rare, even though the legislature expressed a desire to increase the use of alternative dispute resolution. In 2011, a series of measures were taken to increase the use of mediation and strengthen mediation attractiveness. What effect can be inferred from these actions today, over three years after their introduction? This study analyses the main reasons offered for why mediation is not used more, and what should be done to increase the use of mediation.

The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks. For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were: ? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks. ? The averaged sized tree will make it possible to harvest saw timber. ? The trunks can?t be root cut. A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.

Syfte/FrågeställningarSyftet med studien är att undersöka hur idrottslärare på olika grundskolor i Stockholms kommun upplever sin arbetsmiljö. Jag har utgått från tre mer preciserade frågeställningar,Hur upplever idrottslärare i grundskolan sin arbetsmiljö rent fysiskt och psykiskt? Upplever lärarna sin arbetsmiljö som stressframkallande? Kan man se några skillnader mellan män och kvinnor och mellan ett- ämneslärare och två- ämneslärare? Och slutligen hur arbetar idrottslärare för att motverka stress och påfrestningar i arbetet?MetodDenna studie grundar sig på kvalitativa intervjuer. Jag åkte runt till sex olika skolor och intervjuade sex idrottslärare, tre män och tre kvinnor på grundskolor i Stockholms län, avsedd för årskurs F-6. Jag har utgått ifrån Karsaseks och Theorells teori som är en förklaringsmodell till stressens uppkomst på arbetsplatsen.

Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning.

Han kör omkring med en dragtruck efter vilken han kopplar på olika vagnar.

Miljöutvecklingen på de svenska golfbanorna går ständigt framåt, mycket beroende på strängare direktiv i form av mer miljötillsyn och begränsade möjligheter att använda bekämpningsmedel. Golfbanor är viktigt för det svenska näringslivet, som ger jobb, ökad biologisk mångfald och friskvård bland annat. För att kunna utveckla och förbättra golfbaneskötsel är det viktigt med utbildning. Detta har förändrats radikalt från 1980-talet till idag. Utbildning inom skötsel av golfbanor började inte komma förrän på mitten av 1980-talet och utvecklades något under 1990-talet. Under 2000-talet har även utbildning börjat ges på universitets- och gymnasienivå. Golfbanor har länge förknippas med att ha en stämpel av ?miljöbov?, vilket växte sig allt starkare under 1980- och 1990-talet.
