Utveckling av en dynamisk Simuleringsmodell av en skotare
The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-Body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.
Regionalisering och demokratiaspekten : En fallstudie av Region Värmland
This is a study of how democracy is affected by regionalization. The study focuses on values related to the democracy; these values are representative, transparency, participation, anchoring of decisions and accountability. The case study for this essay is the Regional Development Council of Värmland case study of Region Värmland.1997 a proposition was put forward the Swedish government about changes in responsibilities regarding four Swedish counties. It was decided that Kalmar, Gotland, Skåne and Västra Götaland County would be part of pilot project with extended regional autonomy.Region Värmland was formed at 2001 as a Region Development Council and was at 2007 transformed to a co-cooperative Body. Region Värmland has an indirectly elected council, i.e.
Kan hälsa mätas?: En jämförande studie mellan två olika hälsobegrepp
De senaste åren har i Sverige och Europa, bland yrkesarbetande noterats en ökning av långtidsfrånvaro på grund av sjukskrivning samt sjukpensionering. Detta medför stora kostnader för de berörda länderna. I Sverige har debatten om hur detta ohälsotal skall sänkas, förts på olika nivåer och i olika forum. Regeringens utredare för ?Ökad hälsa i arbetslivet?, Jan Rydh, har lyft fram vikten av tidig rehabilitering samt värdet av att kunna identifiera riskpersoner.
Ett nytt sätt att vara i världen-upplevelser av kroppen och fysisk aktivitet i vardagslivet hos personer med förvärvad hjärnskada. En intervjustudie.
Introduktion: Efter en förvärvad hjärnskada kan det inte tas för givet att kroppen upplevs som självklar i vardagslivet. Många har både fysiska och kognitiva funktionsnedsättningar.Syfte: Studiens syfte var att få en fördjupad förståelse för hur personer med förvärvad hjärnskada upplever sin kropp och fysisk aktivitet i det dagliga livet.Metod: Intervjuer genomfördes med 15 strategiskt utvalda personer som hade utretts för förvärvad hjärnskada. De intervjuades vid ett tillfälle 1-5 år efter debuten. Personerna var i yrkesverksam ålder och hade lättare motorisk och/eller lätt/måttlig kognitiv, emotionell eller personlighetsmässig funktionsnedsättning. Intervjuerna transkriberades och analyserades med the Empirical Phenomenological Psychological Method (EPP-metoden).Resultat: Ett övergripande tema och sex huvudteman identifierades.

Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Sambandet mellan steglängd och kroppslängd, ålderns inverkan på steghastighet samt subjektiv gånghastighet jämfört med reell gånghastighet
Bakgrund: Gången är en förutsättning för att förflyttning mellan platser ska vara möjlig. Hela kroppen involveras och det är ett energisnålt och komplext rörelsemönster. Gånghastigheten bestäms av hur många steg per minut och hur långa steg som tas. När gånghastigheten ökar är det främst steglängden som ökas. Självvald gånghastighet är hastigheten som väljs när en person promenerar själv utan att vara påverkad av yttre faktorer, den är ofta relaterad till att minimera energiåtgången.
Rött, vitt, svart - Vedisk kosmologi och klassificering i Ch?ndogya-Upani?ad 3:1-11 och 6
Chapter 6 of the Ch?ndogya Upani?ad has often been treated in works on early Indian philosophy, as well as in some comparative studies on color symbolism. Attempts to place it in a larger framework against the background of late Vedic religion are, however, few, the rationalistic and ?tradition-challenging? appearance of the text having repeatedly been emphasized. But the doctrine contained in the text ? a cosmologic teaching on the three elements constituting the universe, each being characterized by a color (red, white, black) ? and their microcosmic counterparts in the human Body, does have some clear affinities to the worldview of the Br?hma?as and ?ra?yakas, which posits a series of similar correlations (bandhu-) between macro- and microcosmos.
Alla måste duscha - en gympasalsredovisning
SourceURL:file:///Users/sofiahultin/Desktop/AMDex/Summary%20of%20essay.docI my essay I describe my master project Alla måste duscha ? en gympasalsredovisning/ Everyone has to shower ? a school gym presentation. Through my work I investigate possibilities for action and agency in a limiting space; the gymnasium. With the help of Mika Hannulas book Politics, Identity and Public Space: Critical Reflections in and through the Practices of Contemporary Art, I discuss how the stories I tell trough my project can be seen as suggestions for a possible reality. By adding my stories to the old ones (that create our society) I hope they, if only just the slightest, can influence on how we look at reality and on a possible reality.
Nötköttsproduktion i Västerbotten
Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.
Svenska hushålls vedarbete : en fallstudie i Umeåregionen
In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood.
The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials
Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.
Effektutveckling i den koncentriska fasen i bänkpress och knäböj
Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
Hur kan personer med hja?rtsvikt testa va?rden i hemmet, fo?r en snabbare behandling och korrigering av medicinering?
- To be trapped in a roller-coaster That ?s how some of the patients are describing the situa- tion of living with heart failure. To be stuck in their home not knowing if they will have to seek care today and not knowing if they will have the energy to attend that birth- day party later this week.Each year 2-3% of the Swedish population are diagnosed with heart failure, which results in 30,000 new individu- als with the disorder. Cardiovascular disease is rapidly in- creasing in the world and before 2030, people with heart failure will increased by 100%. Our improved living condi- tions and better health have allowed us to grow older and made us more dependent on other types of care, care at home.Today the patients are only looking for changes in weight and if they have excessive water in their Body.
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving Body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
