In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.

The empirical data for this thesis were collected through qualitative interviews.The results that arose when analyzing the theories combined with the empirical data pointed towards five strategies and factors of importance.

 Car seats for smaller children, offers very good protection incase of a collision. Unfortunately for the parents? sake , these car seats is heavy to handle outside the car. For example back and forth home and short errands around town. In other words, all those times when you decide to just take out the car seat and carry it instead of place the baby in a baby carrier.

Abstract:Ambulance nurses have in their everyday work a varied work environment, the pace of work can quickly shift from being calm and structured to be a severe acute situation.Objective: The aim of the study was to describe how professional nurses in the ambulance operations experience their physical and mental work environment in daily practice.Method: A qualitative interview study with semi structured questions was used. The study group consisted of two women and three men, ages between 27?42 years. The study was carried out on an ambulance station in central Sweden. Based on collected data, a qualitativecontent analysis was performed that resulted in three categories.Results: The result showed that the ambulance nurses regarded that it was a lot of heavy lifting.

Taiwan has over the past thirty years experienced a substantial political transformation. Being ruled by Chinese nationalists since World War II, Taiwan started its democratic transition in the late eighties. The new democratic system did not only provide people with freedom to vote, it also marked the beginning of a search for a new national identity. Based on the international theory of constructivism, this paper defines and studies the Taiwanese people?s progression away from a dominant Chinese national identity towards a uniquely defined Taiwanese identity.

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

To become a successful athlete requires several different components in which one of themost significant is the ability to develop their own physical strenght. What weight exercises has the best transfer effects for skating?Participants in the study were 20 male senior hockey players from Div. II in the Västra Gö- talands Regionen in which all participants had at least 10 years of hockey experience.Test subjects had to perform a five-minute individual warm up followed by an opportunity to familiarize with the upcoming exercise. The first on-ice test was a 35 meters sprint test and the second test was an S-cornering agility test.

Hälften av personalen inom äldrevården uppger att de dagligen lyfter tungt vilket kan geskador i rygg, skuldra och nacke som kan leda till arbetsskada alternativt sjukskrivning.Durewall-systemet och Stockholmstekniken är de vanligaste lyfttekniksmetoderna iSverige. På undersökningsplatsen användes Stockholmstekniken. Rapportens syfte är attidentifiera faktorer som associeras med sjukskrivning på grund av smärtupplevelse vidlyftmoment i arbetet inom äldrevården, beskriva eventuella smärtupplevelser vid lyft avboende samt undersöka om eventuell information om lyftteknik är effektivt förebyggandemot upplevd smärta vid lyft av boende. Då undersköterskor återfinns längst ner i svensksjukvårds hierarkiskala har yrkesgruppen svårt att påverka. Studien genomfördes på ettboende i Västsverige med enkäter och omfattade 18 undersköterskor.

Water logistics has long been a problem in order to effectively carry out stump treatment in both thinning and final felling. It is important that the stump treatment? equipment is configured as well as a sufficient amount of water is carried out on the harvester to get a cost? effective treatment. The flow control of the equipment has improved and water can be dispensed more efficient, but still the amount of water on the machine is a crucial factor in the total cost estimate. The knowledge of the tools available to bring water as well as the internal logistics of loading and transport to the felling site is deficient. Increased focus on "smart" solutions to manage water cost is of great importance in order to combat Hetrobasidion spp in both thinning and final felling. The purpose of the study is to describe and summarize different solutions of water logistics at stump treatment in final felling.

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.

Enligt rapporter från Arbetsmiljöverket är arbetsrelaterade besvär som inte beror på arbetsplatsolycka vanliga inom trädgårdsnäringen. Orsakerna till besvären är huvudsakligen en följd av påfrestande arbetsställningar, korta upprepade arbetsmoment och tung manuell hantering. Syftet med denna litteraturstudie var att beskriva vad trädgårdsmästare bör tänka på vad gäller belastningsergonomi för att minska risken för skador i sitt arbete. Sökningar gjordes i databaserna Medline via PubMed, ScienceDirect och Academic Search Elite med sökorden horticulture, gardening, agriculture, ergonomics, pruning, shoveling, stoop, lifting technique and musculoskeletal injuries.Resultatet visade att när det gäller lyftteknik och arbetsställningar bör man i möjligaste mån undvika att utföra dessa med en framåtböjd överkropp och raka ben. Denna kroppshållning visade sig vara sämre i jämförelse med andra tekniker och kroppspositioner med hänsyn taget till påfrestningsgraden av ländryggen.Även vid grävning finns per automatik ett starkt inslag av att luta sig fram med böjd överkropp med den följden att ryggen utsätts för krafter som kan vara skadliga.
