Arbetsmiljövänliga låsvätskor i stötdämpare
This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.
Undersökning av svetsegenskaper för svetsning med rörtråd kontra homogen tråd
Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.
Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
Hur ska tall- och gran bestånd i Götaland gallras för att minska risken för vindskador?
With knowledge of how the southern Swedish forests have been affected by storms the past years, this study intended to find out which factors affect the storm firmness of a stand the most. The study was based on data from stands in the, by the storm Gudrun, affected area. The results of the analyses that tested the stand factors that influence the amount of storm damage to the greatest extent showed that the storm sensitivity of Norway spruce stands were largely due to previous management actions. The factors that could be controlled by thinning and had relevance of storm damage standpoint, according to the results were; the dominant height, volume, basal area weighted mean diameter and stand age at last thinning. In this study, these results are not as clear for Scots pine.

Standardiserad tillverkning av nätstationer
AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.
Patienters upplevelser av att leva med kronisk njursvikt
Bakgrund: Det är viktigt att kliniskt kunna avgöra om idrottaren är tillräckligt rehabiliterad för att återgå till full träning och matchspel eftersom otillräcklig rehabilitering är den största riskfaktorn för återskada i hamstrings. Därför skulle ett test med enkel utrustning behöva komplettera den kliniska undersökningen.Syfte: Studiens syfte är att undersöka vilket samband som finns mellan genomförandet av Nordic hamstring strength test och Asklings hamstring test utifrån skattning av smärta och obehag i samband med testen. Huruvida deltagarnas tilltro till att prestera sitt yttersta i en 90 min fotbollsmatch påverkas efter testerna samt att beskriva obehag och smärta efter testerna för spelare som varit skadad eller inte under senaste sex månaderna.Metod: 22 fotbollsspelare fick skatta sin tilltro till sin egen förmåga att prestera sitt yttersta i en 90 min fotbollsmatch samt skatta obehag och smärta med VAS i samband med testerna. Hamstring Outcome Score användes för att få en helhetssyn av deltagarnas funktion och skadehistoria kring hamstring. Spearman?s rho och Wilcoxon?s teckenrang test användes för att analysera resultatet.Resultat: Korrelationen mellan Asklings hamstring test och Nordic hamstring strength test var moderat (0,4-0,6) dock signifikant på <0,05.

Mentorskap och "the Strength of Weak Ties" - En fallstudie i hur mentorskap under utbildningen påverkar socionomstudenters sociala nätverk
Syftet med denna studie är att se hur socionomstudenters professionella sociala nätverk påverkas av organiserade mentorskap under utbildningen. Den teoretiska ramen utgörs av the Strength of Weak Ties, en teori om de svaga nätverkens betydelse för en individs professionella utveckling och framgång, samt nätverksteoretiska grunder och en litteraturgenomgång kring fenomenet mentorskap. Studien är genomförd som en fallstudie och fallet ifråga är mentorsprogrammet inom ramen för socionomutbildningen med inriktning verksamhetsutveckling på Malmö högskola. Datainsamlingen har skett genom en enkätundersökning bland de mentorer och adepter som genomfört och avslutat mentorsprogrammet samt intervjuer med nyckelpersoner inom organiseringen av det. Resultatet och analysen visar att det finns många indikationer på att studenternas sociala nätverk utökats med hjälp av mentorskapet.
Kaizen i praktiken inom Primärvården
The aim of the study was to support the ongoing kaizen work at a medical centre. Two main topics have been addressed in this study:? Find a solution to ensure that the kaizen decisions are followed and will get a strong grip in the organisation.? Support the kaizen process by giving advice on how to structure the meetingsand how the kaizen work could be done more effectively.The study started with a visit to the medical centre to observe the kaizen process and the attitudes among the employees. The employees were asked to fill in a survey about the kaizen work at the centre. The final recommendations given have been based on this and also information gathered from other medical centres which work after the same kaizen principles.
Mycket snack och lite verkstad - En longitudinell studie av NPS och konsumentbeteende
The Net Promoter Score (NPS) has been claimed to be the single most reliable indicator of firm growth and has gained wide adoption among companies in a broad range of industries. This is despite a lack of rigorous scientific testing. The purpose of this study is to examine the predictive strength of the question "How likely are you to recommend [.] to your friends and colleagues " that the metric is based on: how well does it actually predict future consumer behavior Furthermore, the report aims to create a greater understanding of the factors that explain a person's word of mouth (WOM) intention and which behaviours cause that intention to change. A longitudinal study was conducted of 304 consumers' WOM intention regarding two non-carbonated drinks and their subsequent WOM and purchase behavior. The analyses show that the behaviors are captured by the metric to some extent.
Alkoholintag efter träning och dess inverkan på muskeluppbyggnad och återhämtning hos vuxna män - En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Alcohol consumption after training and its effects on muscle gain and recovery adult menAuthor: Frida Carlstedt, Puck JanssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: Today, the Swedish population exceeds the recommendations for alcohol intake while advised to move at least thirty minutes a day. It is well established what happens if you drink alcohol before a workout or if you workout the day after an alcohol intake, but it is less well established how muscle gain and recovery are affected by an intake of alcohol in the phase of recovery.Objective: The objective of this review is to investigate if there is a relation between alcohol intake after a workout and effected recovery and muscle gain. This was performed by measuring the outcomes cortisol, testosterone, creatine kinase as well as different measures of muscle strength. The issue was ?Does an intake of alcohol after training affect recovery and muscle gain??Search strategy: A systematic review in the databases PubMed and Scopus with the MeSH-terms: exercise, muscles, recovery of function, training, athletic performance, performance, sport, alcohol drinking, alcohols, alcohol and ethanol.Selection criteria: Criteria for articles to be included in this review were that they would be RCT- and human studies in healthy subjects as well as containing an ethanol intake after a physical activity that consisted of weight training in the form of resistance training or other forms of activity that promotes strength.Data collection and analysis: A systematic search for literature as mentioned above (search strategy) was performed as well as an analysis with the SBU quality review template for randomized studies, and a quality review for each measure of outcome according to Gothenburg University summarized evidence template for measures of outcome.4Main results: Many studies are authored by the same group of researchers and/or are of a lower quality.
Eurocodes : Beräkningsjämförelser mellan eurocodes och BKR
In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.
