This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

AbstractTitle: To Market a Company with the Help of Nationality ? A study in how marketing and branding works and is being perceived when it focuses on nationalityAuthor: Frida HanssonSubject: Media and Communication Studies CPeriod: Fall semester 2010Length: 38 pagesTutor: Else NygrenAim: Companies and various corporations are always on the hunt for the next big thing in marketing. One idea to market themselves and give them a chance to separate themselves from the cluster of companies aspiring to take your costumers away could be to market themselves with nationality. To investigate why and how some company?s chose to market themselves with nationality, and also study how this kind of marketing is being perceived by customers and non ?costumers.

Bakgrund: Unilateral benträning är ett relativt outforskat område inom träningsvetenskapen. Traditionellt genomförs fysträning för intermittenta idrotter bilateralt, trots att idrottens rörelser sker unilateralt. Det finns många studier som behandlar samband mellan agility och effektutveckling, men få som har undersökt skillnaden mellan unilateral och bilateral effektutveckling sett till agility.Syfte: Syftet med denna studie var att undersöka om unilateral effektutveckling har en starkare korrelation med agility än vad bilateral effektutveckling och agility har hos kvinnliga fotbollsspelare i division 2.Metod: Kvinnliga fotbollsspelare (n=13, ålder 23 ± 4 år) utförde vertikalhopp med tilläggsbelastning på båda benen, vänster ben och höger ben på 20 kg, 30 kg, 40 kg samt för båda benen på 50 kg och T-test och Pro agility test. Effektutveckling i förhållande till kroppsvikten på båda benen (PBbw), vänster ben (PVbw) och höger ben (PHbw) analyserades och korrelerades sedan mot T-test (Ttest) och Pro agility test (Proagility).Resultat: Signifikanta korrelationer hittades mellan agility och både vänster unilateral (PVbw-Ttest, r = -0,578) och bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) effektutveckling, där korrelationen bilateralt var starkast. Ingen signifikant korrelation hittades mellan höger ben och agility.Konklusion: Bilateral effektutveckling hade en starkare korrelation med agility än vad unilateral effektutveckling och agility hade hos kvinnliga fotbollsspelare i division 2..

Något av det svåraste som kan drabba oss är när en vän, familjemedlem eller släkting går bort eller drabbas av en sjukdom. Döden är en naturlig del av livet, men känns detta till trots jobbig eller rent av orättvis då den slår till. I de flesta fall är döden även resultatet av en sjukdom, en sjukdom som med dagens kunskap kanske hade varit möjlig att undvika. Eftersom döden i många fall har varit lite av ett mysterium genom människans historia har vi också lärt oss att rädas den. Nu, när den tekniska utvecklingen öppnar nya dörrar för att i förväg göra riskbedömningar av möjliga sjukdomar som kan drabba individen, så drar sig många undan.

The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.

The  construction  industry  is  a  costly  business  such  in  respect  of  capital  for  most construction defects which then require rework, tear down and rebuild again. This study is  meaningful  awareness  of  tools  that  can  reduce  this  best  through  communication  and information sharing between the parties.  The  construction  industry  is  known  as  temporary  projects  organizations,  where  the construction  project  consists  of  several  actors  who  have  to  communicate  and  share information  between  them  to  avoid  mistakes  later  in  the  build  time.  These  actors  are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to  create  a  routine  for  the  association  and  the  shattering  of  these  actors.  To  implement such  behavior  using  a  tool  such  as  BIM  in  the  industry  whose  size  perhaps  is indescribable may be a very hard task.  BIM (Building Information Model) could be seen as the solution to this problem because it  acts  as  a  portal  where  the  actors  involved  must  sign  in  and  communicate,  share information, and eventually create a behavior, a routine for this association and division of  the  actors  following  the  end  of  the  project.  The  technology  could  help  the  involved from  the  beginning  of  the  project,  already  in  the  model  stage,  break  down  and  prevent any construction barriers when the building has been placed in the works.

A significant amount of a teacher?s work consists of evaluation and marking of the students, which involves a great responsibility. This essay put the teacher?s evaluation of the students in focus. Today?s course Idrott och hälsa A, at the upper secondary school level, consists of 100 points and all students take this course apart from students attending apprentice programs.

When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

The thesis hears content-error in relation to agreements closed by electronic means. The purpose of the thesis is to elucidate how the rules in 32 §(1) AvtL apply to agreements closed by such means and to evaluate its suitability. The elucidation is done on the basis of, the rules? adequacy in relation to their objectives in collaboration with a comparative view on a selection of international legal framework under private law, such as DCFR, UNCITRAL Model Law, UNIDROIT Principles and CISG.Since Sweden lack a specific regulation for electronically closed agreements, all modern closing methods will be evaluated from the dated outlook of the Swedish Contract Act. In relation to entirely automated processes which results in the closing of an agreement, particular difficulty arise in correlation with prerequisites, which requires a human stance.

The purpose of this study is to examine discursive change regarding mathematics and language in the Swedish primary school curriculums. The study analyzes pedagogical discourses represented within the curriculums and how they represent different pedagogical theories in relation to discursive and social practice. The analysis shows a change towards a more language oriented curriculum discourse in mathematics which still carries an intertextual and discursive heritage from the prior curriculums. In relation to the early curriculums of the Swedish primary schools the former explicit differentiation of students becomes implicit as the language skills become of increasingly importance..

Bakgrund: Medvetenhet om kropp och rörelse nämns ofta som en viktig fakor i att öka prestationsförmåga, undvika skador, nå högre livskvalitet och förbätta sjukdomstillstånd. Det har länge funnits ambitioner att förbättra rörelse genom ökad medvetenhet. Feldenkraismetoden är en metod för att förbättra rörelse genom förhöjd rörelsemedvetenhet och är förenlig med nutida vetenskap men förhållandevis lite empirisk forskning stöder metodens effektivitet. De flesta tidigare studier har varit på någon form av dysfunktion och ofta subjektiv upplevelse snarare än objektiva värden. Det har varit svårt för Feldenkraispedagoger att finna rätt mätmetoder för att utvärdera metoden.Syfte: Studiens syfte är att utvärdera effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på rörelse hos friska personer genom kvantitativ mätning.Metod: Friska kvinnor i en experimentgrupp (n=4, 30±7 år) och en kontrollgrupp (n=4, 26±2 år) testades med fem kvantitativa rörelsetester; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test och upper quarter Y-balance test, innan och efter en intervention ledd av en auktoriserad Feldenkraispedagog där experimentgruppen genomgick tio träningsfällen enligt Feldenkraismetoden under fem veckors tid.Resultat: Signifikant förbättring (P?0,05) i förhållande till både förtest och kontrollgrupp sågs vid star excursion balance test för vänster ben.Slutsats: Träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden verkar kunna leda till förbättring i kvantitativt mätt rörelse hos friska kvinnor.
