Människor får möjlighet att ses och mötas i stadens offentliga rum. För att försäkra att staden på ett hållbart sätt planeras för dess invånare, behövs kunskap kring hur det sociala livet i offentliga rum fungerar och även hur vi kan bibehålla och utveckla dess funktion som mötes-, aktivitets- och uppehållsplats. De offentliga rummen i en stad är till för stadens alla invånare oavsett kön, etnicitet, ålder, ekonomi osv. Dess användning skiljer sig genom tiderna och domineras idag främst av frivilliga aktiviteter dit bland annat sociala aktiviteter räknas. Det finns varierande sätt att ta det offentliga rummet i anspråk. Konflikten mellan föreskrivna och unika användningar genererar en social friktion som främjar mer öppna och tillgängliga offentliga rum för fler grupper. Genom litteraturstudier med utgångspunkt i det offentliga rummet studeras det sociala livet och dess förutsättningar.

The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

Background: Companies and organizations of today spend large amounts of money on IT-based business solutions. Such business solutions normally include business- consulting and software-creation (IT-related services). Due to the rapid development of the technology within this field of business the IT-customers find it difficult to select among potential suppliers on objective grounds.Purpose: To increase the understanding for the professionl approach of the people involved in the sales- and purchase process of IT-related services in a business-to-business context. The study is taking the buyers'as well as the sellers'perspective into account when analyzing the process. Method: The empirical findings were collected from eight companies in Linköping and Stockholm.

Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.

The aim of this study was to describe and analyze how social workers working in social services using evidence based practice with special focus on the clients? experiences and wishes as source of knowledge in collecting information, assessment and decision. To get to the social workers experiences and descriptions we used a qualitative method with semistructured interviews. The empiric material of the study consists of eight interviews with social workers working in different social offices in different areas, in southern Sweden. The main result of this study was that social workers use clients? experiences and wishes differently in different parts of the investigations.

Enligt statistik föreligger det en högre frekvens av tonårsfödslar i detta specifika brukssamhälle i jämförelse med en närliggande mellanstorstad.  Det existerar ofta en speciell bruksanda i brukssamhällen där arbete många gånger föredras framför utbildning. Uppmuntrar denna mentalitet till att skaffa barn i ung ålder och vilken betydelse och påverkan har mödrarnas ålder vid barnafödande? Skapar tonårsmammorna sin identitet genom att reproducera mödrarnas livsstil? För att ta reda på detta har fem tonårsmammor blivit intervjuade och fått lämna sin livsberättelse. Intervjufrågorna var uppdelade i tematisk ordning för att få en följsam berättelse. En professionell person som är anställd i en stödgrupp på orten har blivit intervjuad för att få en nyanserad bild av tonårsmammornas situation.

The vision of this thesis was to create a concept that can be used as a base for amachine construction. The purpose of this project was to use different methods todevelop a concept that on the best way meets the sat up requirements. This projecthas been divided into three stages/parts; principle, primary and the final solutionstage.This thesis has been conducted in collaboration with Västkustägg AB. It is aconstruction project designed to construct a machine that will automatically putlabels on the egg packages. Västkust AB wanted to automate this process.

AimThe main aim of the study was to investigate the difference in bilateral deficit between rowers and sprinters during maximal eccentric/concentric muscle actions.? Are there any significant differences in bilateral deficit between rowers and sprinters?? Do the amount of years in practice effect the bilateral deficit?MethodFourteen male subject participants divided in 2 equal sized groups (7 individuals in each group; rowers and sprinters) performed maximal unilateral/bilateral eccentric and concentric muscle actions in a leg press machine at a velocity of 0.2m/s. The range of motion in the knee joint was 70° ? 140°. Dependent t-tests have been performed within each group pre and post test.

On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

The primary purpose of this essay is to study and describe what single adoptive mothers believe to be significant motives when considering adoption. This essay also describes how single adoptive mothers experience parenthood in relation to their expectations. The theoretical perspectives applied to analyse the empirical data are existentialism, the identity making process, and social constructionism. The method of this study is qualitative based on seven interviews. The material has been analysed by condensed meaning units and themes with a phenomenological approach.

En fungerade erfarenhetsåterföring leder till effektivare och lönsammare processer. Det är isynnerhet viktigt för Skanska och Ikeas industrialiserade bostadskoncept BoKlok, där sammatyp av arbeten ständigt upprepar sig. Skanska har ett verktyg för erfarenhetsåterföring somde kallar Normallägen och beskriver olika arbetsmoment i text och video. Arbetet pågårmed att utvidga innehållet för Normallägen och i dagsläget finns inga för markarbeten inomBoKlok.Syftet är att undersöka hur erfarenhetsåterföringen fungerar idag och vad som fungerarmindre bra i projekten. Finns det erfarenheter som kan användas som underlag till framtidaNormallägen.Arbetet bygger på intervjuer, litteraturstudier och information från Skanska och BoKloksintranät.Resultaten visar att den erfarenhetsåterföring som sker idag oftast är muntlig mellanarbetsledningen på olika projekt och där kunskapen är personrelaterad.

Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

Uppsatsens syfte var att studera industriellt köpbeteende för branschen för prefabricerade trähus. En teoretisk studie har därför genomförts där köpsituationer och dess påverkan på köpprocessen, köpbeslutsgruppen samt kriterier för val av leverantör studerats. Datainsamling har skett genom telefonintervjuer med tre av Sveriges fyra största byggföretag, intervjuerna har genomförts med personer med god kunskap när det gäller inköp av prefabricerade trähus på dessa företag. Resultatet av vår uppsats visar att den den vanligaste köpsituationen för företag som köper prefabricerade trähus är nya köp men att det även förekommer direkta återköp främst genom avrop på ramavtal. De personer som ingår i köpbeslutsgruppen är initiativtagare, användare, köpare, influerare, beslutsfattare och informationsbevakare, vilket överensstämmer med teorin.
