Arbetsmiljö i stora mjölkkobesättningar :

Earlier studies have shown that musculoskeletal disorders among animal keepers are more frequent than in other occupations. Most of the farms have expanded and the farmers who used to work alone have suddenly become a work manager with several employers. There are only a few studies made on the work environment in dairy farms. Our study is based on a questionnaire and is a part of a project called large dairy herds. The study is based on data from the persons who milk most of the time. The questions they had to answer were about the work environment, musculoskeletal disorders and the psychosocial environment. The results of the survey are presented in diagrams and figures. It was common that the dairy producer themselves answered the questionnaire.

Underlag till energieffektiviserande åtgärder i nätstationer

Umeå Energi are working towards a goal, that in the year of 2018, they will be completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. In many residential areas, the distribution grid is designed and rated for electric heating as the heating in the houses. As many of the houses later has been converted to other types of heating, their electricity use has decreased and the total power output from many of the secondary substations has decreased significantly. Because of this, many of these stations today are well oversized, which in turn means that the energy losses in these stations are unnecessarily high.In this degree project, 25 secondary substations have been studied, all located in residential areas in and around central Umeå.

Förbättring av Egenvärmehus : En fallstudie av ett flerbostadshus, Kv. Fyrtornet

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

Ur led är tiden: En studie av metoder att korta ledtider inom forskning och utveckling

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening lead times and how these methods effect the lead times in research and development.

Delaktighet, Dialog & Demokrati

The concept of democracy is of importance to the Swedish educational system. The best proof of that is the central position democracy has had in the education program we attended at the Örebro university. This study analyses the concept of democracy and its leading foundation, namely the so-called ?deliberative dialog?. The last is belived to be an ideal of democracy which schools in Sweden should follow.

Fo?rba?ttringsfo?rslag pa? automatisering av bagagehantering

This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.

Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

Kvalitet i brödvete :

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Samband mellan målorientering, motivationsklimat, upplevd prestation och tävlingsrelaterad ängslan/oro hos ungdomar i alpin utförsåkning

Achievement Goal Theory (AGT) utgår ifrån att alla individer vill visa sin kompetens vilket tar sig uttryck i två målinriktningar; ego och task. Individen påverkas av omgivningen som driver ett motivationsklimat som kan uttryckas i samma typer av målinriktning. Motivationsklimatet och målinriktningarna anses påverka hur individen agerar och hanterar t.ex. ängslan/oro och prestation. Denna studie behandlar samband mellan individuella målinriktningar, upplevt motivationsklimat drivet av tränare, träningskamrater och föräldrar, tävlingsrelaterad ängslan/oro och upplevd prestation.

The objective of the essay was to identify the nursing care required by a dog suffering from heat stroke and how to educate and advice the owners how to start treating their dog and prevent the condition from occurring in the first place. The essay is based on a literature study. Several databases were searched for scientific research to try find answers to the issues. Keywords concerning the subject were used and mixed in different combinations to sort out the suitable studies. The results of the study indicate that the dog should be cooled by the owner directly after detection. The most crucial issue is to reduce the body temperature as quickly as possible or the morbidity will worsen.

Potentiellt förorenade områden i Ljungans avrinningsområde i Västernorrlands län : Finns det anledning att prioritera om arbetet med avseende på riskläget för översvämning, ras och skred?

Due to the climate change natural disasters expects to increase and in some areas the conditions for dissemination of hazardous pollutants from contaminated areas could be affected. Different inventories and mapping has been made to identify areas of risk for flood or avalanche around the country. At the same time inventory and treatment of potential polluted areas (MIFO objects) is progressing. In Ljungans run of area in Västernorrlands county is a exposed area due to the amount of clay and silt in the ground that are sensitive in the context avalanche. The area has also a lot of MIFO objects and risks of flood.This essay aims to investigate what data material that is available regarding MIFO objects, flood- and avalanche risks in Ljungans run of area in Västernorrlands county.

Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Latitudinal patterns in body size of Roesel?s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution

Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

Bostadssektorns koldioxidutsläpp

Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.
