GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.
Effekten av nutritionsbehandling på funktionell återhämtning efter stroke, en systematisk översiktsartikel
Sahlgrenska Academy at University of GothenburgDepartment of Clinical NutritionAbstractTitle: The effect of nutritional treatment on functional recovery after stroke, a systematic reviewAuthor: Ingrid Blankenau and Amanda LindbladSupervisor: AnneMarie GrönbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTS Type of paper: Examination paper, 15 hpDate: April 13, 2011Background: Every year 30 000 people in Sweden suffer from stroke. This costs society about twelve billion SEK. Many stroke survivors experience functional impairment which may lead to difficulties for them to meet their nutritional needs. Nutritional treatment is important in the recovery process after stroke as malnutrition increases the risk of complications.Objective: To investigate the possible effect of nutritional treatment on functional recovery after stroke.Search strategy: The search was conducted in the databases PubMed, Scopus and Cochrane by using the English keywords stroke, nutrition, rehabilitation, functional outcome, recovery, acute stroke, ischemic stroke, ischemic acute stroke, nutrition therapy, brain hemorrhage, functional recovery and nutritional rehabilitation.Selection criteria: Studies published before 2001 conducted on human subjects who suffer from stroke where they measured functional capacity and did a nutritional intervention, written in English, Swedish or Norwegian, and did not have to be requested from the library.Data collection and analysis: A systematic search was performed in PubMed. Studies which had an interesting heading were examined and abstract read.
Mätning i nätstationer - nyttor och problem
The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.
Effekten av verbal feedback på maximal isometrisk armbågsflexion
Under idrottsliga aktiviteter, är det kutym bland deltagare och åskådare att ge verbal feedback till andra eller till sig själv med syfte att förbättra prestationen. Vissa använder verbal feedback, andra inte. Vad ger då detta för effekt? Är dessa två fenomen, verbal feedback och prestation, på något sätt relaterade till varandra? Resultat från en sådan studie, skulle vara fördelaktig för idrottare på alla nivåer, såväl som för idrotts- och rehabiliteringsforskning som baserar sina fynd och metoder på empiriska resultat erhållna från mätningar av individers förmåga att utveckla kraft under olika förhållanden. Huvudsyftet med denna studie är att undersöka effekten av verbal feedback på en maximal isometrisk armbågsflexion.
Värmeåtervinning ur spillvatten i befintliga flerbostadshus
Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

Kalvningsintervall hos svenska köttkor : finns det genetisk variation som kan användas i avelsarbetet?
The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.
Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
Uppstart av Totalt Produktivt Underhåll på Tour & Andersson AB
In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM).
Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.
Pedagogisk intervention vid audiologisk rehabilitering med hjälp av en textbok. En randomiserad kontrollerad studie.
Hearing is considered to be the most important sense for the communication between people. Several studies have shown that hearing loss can lead to deterioration in quality of life, reduced social activities, feelings of alienation and hence the increasing incidence of depression symptoms.An early audiological rehabilitation is a prerequisite for proper communication among people with hearing loss. Knowledge has been shown to be of great importance and structured learning and individually targeted approach can be expected to facilitate the audiological rehabilitation.The purpose of this study was to examine the effect of an educational effort for people with hearing loss where the effort was made in the distance within the audiological rehabilitation and was followed-up by professional phone support, through a randomized controlled study.The study group consisted of 69 hearing aid users who were randomized by an independent person into two groups, an intervention group and a control group. The intervention group (n = 33) had access to the book "When the sounds are weaker - on hearing and hearing aids". The group received weekly topic-based information related to the different chapters of the book, in five rounds.
DSP-baserat instrument för fjärrmätning av larmnät
Fält Elektronik AB i Kalix utvecklar och tillverkar bland annat larmsändare för fast uppkopplade larmnät. Fast uppkopplade larmnät används för att åstadkomma övervakad och säker överföring av larm och annan information mellan tekniska system för skydd och säkerhet. Larmöverföringen är ständigt övervakad från larmanläggningen ända fram till larmcentralen. Ett problem som idag finns i larmnät är att om man tappar kontakten med en larmsändare så vet man bara att man tappat kontakten, men inte varför. Därför vill man nu utveckla ett instrument som kan mäta och kontrollera vad som orsakar att uppkopplingen bryts t.ex.
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.
Majsensilage - partikelstorleksfördelning och hygienisk kvalité :
Fieldstudys on 22 farms (23 silos) to study relationships
between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us.
Particle size of maize silage was determined using the New Penn State Forage Particle
Separator. SLU Skara made a special sieve for us, that had larger holes than de original
sieves. The samples were shaken after instructions and then the
material was weighted. We have also been taking out samples for microbiological
analyses from the silos on 13 of the farms.
