Utnyttjandet av ligghallar hos dikor och kvigor av köttras under vintern :

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.

Hur påverkar naturvårdsåtgärder mängden av vedlevande insekter : Manuellt dödade träd vs självdöda

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Humanitär intervention och suveränitetsprincipen : En studie om huruvida stater har påverkats av framtagandet av "responsibility to protect".

The reason behind this essay has been to study if previous research is relevant for Jehovah?s Witnesses in Sweden and see if secularization has affected the organization or not. The empirical material is made from two qualitative group- interviews and open observations during two meetings in the Kingdom Hall. These studies were performed in Oskarshamn and Mönsterås during the month of February. The reason that these studies have been limited to Oskarshamn and Mönsterås is mainly because they were the only ones willing to do an interview.  According to previous research by James A.

Ingen skillnad, men ändå olika : En kvalitativ innehållsanalys av Försvarsmaktens webbplats ur ett genus? och organisationskulturellt perspektiv

This study aims to analyse the Swedish Armed Forces website. Through a content analysis with a gender- and organisational culture perspective the study attempts to see how the Swedish Armed Forces portrays women and men. The Swedish Armed Forces is one of the strongest masculine gender coded organisations in our time. Distance caused by gender roles between women and men has been a problem within the organisation, and at the same time they have expectation?s from the society to alter these problems.

Solenergi på Kvarnholmen

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Det regionala inrikesflyget : - en studie om framgångsfaktorer

The integration of the Internet in our society has shaped alot of the things we do in our lives. The Web allows us to achieve certain things directly through our computers, such as reading the paper and paying our bills. But this integration has also lead to another interesting change. Activists have begun to unload their operations onto the Net instead of holding on to the more traditional demonstrations performed in squares. This study aims to look into the world of cyberactivism and examine how cyberactivists experience the way activism has changed as a result of using the Internet.

Optimering av ett småskaligtvattenkraftsystem

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Training techniques used in training horses (Equus caballus) : with a focus on positive reinforcement

Instrumental conditioning, the use of reinforcement and punishment, is used when training horses and these procedures may have different consequences regarding animal welfare. The aim of this study was to investigate what kind of reinforcers that are used in training horses and when these reinforcers are used. This study has its focus on positive reinforcement and its advantages and disadvantages. Interviews of five A-level and B -level equestrian coaches about their training methods were conducted to complement the literature search and give a greater understanding to why certain methods are used or not in training horses. The results show that negative reinforcement seems to be the foundation of training horses whereas positive reinforcement is used but not to the same extent.

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

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%.

The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Geodatasamverkan - nyttan för en kommun att delta

The Swedish model for developing the national infrastructure is based on increasing the cooperation between municipalities, government and businesses. The method to establish the infrastructure in Sweden is the geodatastrategin. The effort to implement the geodatastrategin has resulted in an interaction model, Geodatasamverkan. The purpose of this study is to alert municipalities and to investigate the usefulness of their participation in Geodatasamverkan. The study also presents examples of different applications where geodata can be used within a municipality. The report is based on literature reviews, surveys and interviews. Online Surveys were sent to some of Sweden's municipalities to get an overall idea of ??how they make use of geodata and their general attitude towards Geodatasamverkan.
