The importance of shade for dairy cattle in Sweden.

Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.

Kyrkans sociala ansvar i Argentina : En kvalitativ undersökning om ansvarsfördelning mellan kommun och kyrka i Salta, Argentina

The aim for this master thesis is to create an understanding of the intersubjective processes of how individuals are experimenting with their identities in social media and the consequences for the identity and embodiment. The thesis is completed with the help of discourse analysis and a starting point in four complementary theories. Central to the implementation of the analysis is the concept of diffraction. Therefore the thesis is, which is reflected in the choice of theoretical approaches and methods, critical to many aspects of classical philosophy of science and method. The empirical material is based on interviews.

Hur ett mindre bemanningsföretag kan organisera försäljning ? där fördelarna överväger nackdelarna

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

Omorientering och förändring Den ryska utrikespolitiska doktrinen under Vladimir Putin

AbstractThis thesis analyzes the Russian Foreign Policy Doctrine from a broad theoretical perspective, with the aim of describing and explaining the doctrine using a number of theoretical approaches. Russia's foreign policy has undergone substantial changes since Vladimir Putin became president in the year 2000, involving a radical shift in foreign policy objectives and thereby moving away from the more confrontational and distrusting policies which characterized the Boris Jeltsin regime. Putins doctrine, based on pragmatism and seeking partnership and collaboration with the West, can be described as a near revolutionary re-orientation of Russia's foreign policy guidelines, meaning a transformation of the country's self image which implies a rejection of great power status and a search for a new role in the international community.Our thesis has examined explanatory variables such as the domestic political situation in Russia, the contemporary international system and President Vladimir Putins system of beliefs in order to describe and explain the doctrine. Our results show that the doctrine is largely a product of Putins personality, values and beliefs, but also to a large extent a consequence of necessities, namely the poor Russian economy and the fact that the country no longer can withstand an all out conflict with the West involving an excessive arms race.Keywords: Vladimir Putin, pragmatism, realism, domestic politics, radical change..

Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden

Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.

VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :

Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

Den viktiga historien : Historiesyn och historiemedvetande i studentexamensuppsatser från åren 1877 och 1929.

The purpose of this thesis is to identify and analyse the view and consciousness of history present in essays written by Swedish high school students in 1877 and 1929. A theoretical framework was established in order to accomplish this, based on the theories of Peter Aronsson and Jörn Rüsen (through Lars Andersson Hult) that defines consciousness of history through a matrix that expresses a progression as well as a scaling complexity. Furthermore, the theories of Knut Kjelstadli and Magnus Hermansson Adler were adopted to establish two different types of view of history: one adhering to a view of history where groups and individuals are seen as integral to the progression of history, and the other explains historical process through more functional explanations, such as dependant on cultural and social structures.This framework erects ideal-types of different types of view and consciousness of history, and the thesis at hand strives to categorise the different kinds of view and consciousness of history found in the studied essays in accordance with these ideal-types through two different models based on the above mentioned theories.The findings presented here largely point to a view of history that is largely centered on an actor-oriented view of history, where individuals such as kings and generals are given a central position when historical events are being narrated, and is present in both 1877 and 1929, with some shifting nuances. As for the consciousness of history the lion part of the analysed texts can be seen adhering to a more traditional type of consciousness in 1877, although a slight shift can be seen towards a more complex type of consciousness in the texts from 1929..

?Det är inte Rocket Science att göra Science?. En kvalitativ studie om hur Citizen Science-plattformar organiserar sig för att motivera till deltagande

Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.

Validitet av observationsbaserade mätningar av armarbetsställningar hos pappersbruksarbetare

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

Kvinnors syn på ohälsa inom en mansdominerande industri

Syftet i studien var att få en djupare förståelse för hur kvinnor som arbetar inom en mansdominerande industri förhåller sig till ohälsa. I bakgrunden presenteras kvinnor och mäns position i samhället samt hur kvinnlig sjukskrivning ser ut på ett nationellt och internationellt plan. Hur normer och synen på kvinnor ser ut och påverkas på en arbetsplats som domineras av män. Studier visar att kvinnor står för procentuellt högst antal sjukfrånvarodagar och att bidragande orsaker till detta kan vara biologiska skillnader.  Uppsatsen bygger på en kvalitativ ansats där sex intervjuer har använts som metod, detta för att få den djupa förståelse som studien annars hade kunnat gå miste om ifall andra metoder använts. Resultatet visade tydligt att majoriteten av de undersökta kvinnorna hade svårt att beskriva sina åsikter kring företaget.

Enegiutredning Hotell Princess

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

Strategier för bevarandet av natthimlens synlighet : en diskussion om motiv & åtgärdsförslag i ett antal internationella strategidokument

Ljusförorening är ett relativt modernt fenomen som allt mer påverkar tillgången till en stjärnklar natthimmel. Det finns en mängd olika internationella organisationer som arbetar för att minska ljusföroreningar och för att bevara natthimlens synlighet, bland andra International Dark-Sky Association, Royal Astronomical Society of Canada och Starlight Initiative. I den här uppsatsen undersöker jag ett antal strategiska dokument genom textanalys, för att analysera deras huvudsakliga motiv till förändringar och för att få en överblick över vilka sorters åtgärder som dessa organisationer föreslår. De analyserade dokumenten är Astrolabs Practical Guide for Lighting, Dark Sky Societys Guidelines for Good Exterior Lighting Plans, International Dark-Sky Associations Practical Guide, Royal Astronomical Society of Canadas Dark Sky Guidelines, Patersons Sark ? Dark Sky Island Lighting Management Plan, Flagstaff Dark Skies Coalitions Lighting Tips, Starlight Initiatives Defence of the Night Sky and the Right to Starlight och Narisda och Schreuders Light Pollution Handbook.

Framställningen av Judas Iskariot : En förändringsprocess?

The purpose of this essay is to identify the criticism that has been directed towards the traditional description of Judas Iscariot as a traitor. After a survey and analysis of the critical revisionists' arguments, a discussion follows regarding the possible effects this may have on future ways of describing Judas Iscariot.Based on the results that have been elucidated, this essay concludes that the traditional description of Judas in recent times has been forced to endure fairly strong criticism. To summarize this criticism, the main argument raised by today?s revisionists consists of linguistic and historical phenomena. According to these Judas Iscariot has been subject to a, according to some, deliberate demonization; where he over time has become portrayed as more blameworthy.

Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
