Uv-ljus som vattenrening i kylanläggning

I det här projektet har uppgiften varit att rena vattnet i Aqua Interiör i Laholms egen tillverkade vattenmöbel med hjälp av uv-ljus. Dessa möbler hyr de ut till kunder för att kunna få ett lagom kallt vatten med eller utan kolsyra. Vattenmöblerna är direkt kopplade till det befintliga vattensystemet. Ett problem som de tidigare haft är att de inte kunnat ha sina möbler på sjukhus eftersom möblens beskaffenhet medför en ökad bakteriehalt i vattnet.Denna bakteriehalt kommer dock inte upp till den gräns som livsmedelverkets satt som icke tjänligt. På sjukhus finns ett högre krav på vattnets kvalité där inga anmärkningar får finnas på vattnet.

Geosynteter för hållbara vägar : Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät

The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.

När världen kom till Föra : om forskningens syn på Ölands kristnande

This paper aims to give an account of, and to discuss the view-points and theories of different researchers on the christianization of Sweden, especially the province of Öland, during the early middle ages. Its purpose is to investigate how, and in what sense, their positions can be said to correspond to what we may know of the historical ?facts?. This will be possible by comparing different points of view with a study of the development in a single parish. An overall difficulty however, is the nature of the sources relating to the time in question, they are scarce or even non-existent.Part I of the paper consists of an outline of the field of research and the different theories put forward on the subject.

Han, denne och han eller hon : Om generiska pronomen i juridisk myndighetstext

In this paper, generic reference in a collection of juridical texts is examined, with focus on third person singular pronouns. The object of the study is to find out which generic pronouns occur in the material along with their relative distribution, but also to display further use patterns and to offer plausible explanations for these patterns. Another object is to evaluate whether the use of generic pronouns corresponds with language planners? recommendations for non-sexist language. The corpus studied consists of Rikspolisstyrelsens författnings­samling (?Statute Book of the Swedish National Police Board?), comprising 172 documents written between 1974 and 2009.The study is divided into two parts.

Latitudinal patterns in body size of Roesel?s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution

Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

Arbetssätt kring värdeflödesanalys för tillverkning av marina båtmotorer på Volvo Penta

Volvo Penta has been producing boat engines since 1907 and are world leading in this seg­ment. They have today an extended range and also sell industrial power stations. Quality, safe­ty and environmental care are three core values for Volvo and together they strive to give their customers the right product with the right quality.Volvo has developed a production system named Volvo Production System, VPS, and one of the pillars is continuous improvements. Within this pillar you can find value stream map­ping, which is used to analyze the value stream through the process. This tool gives a wide perspective and helps to keep focus on the entire process instead of just parts of it.Volvo Penta in Vara has earlier done value stream mapping but without good results since they didn?t take set-up times and imbalances in account.

Riskfaktorer för postoperativa infektioner i operationssalen- En litteraturstudie

Runt om i världen utförs miljontals kirurgiska ingrepp varje år, sedan 1840-talet har utveckling skett för att reducera antalet vårdrelaterade infektioner. Postoperativa sårinfektioner är den vanligaste typen av vårdrelaterad infektion och utgör ett stort lidande hos patienten. Som operationssjuksköterska är det viktigt att ha kunskaper om riskfaktorer för postoperativa sårinfektioner för att kunna sätta in adekvata omvårdnadsinsatser. Mot denna bakgrund var syftet med denna litteraturstudie att belysa riskfaktorer för postoperativa infektioner som finns i operationssalen med frågeställning hur operationssjuksköterskan kan påverka förekomsten av postoperativa sårinfektioner. Metoden som används är litteraturstudie där databaserna Cochrane och Pubmed har genomsökts.

Hållbar vattenplanering : en diskussion med utgångspunkt ur fyra bristområden

Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.

Utvärdering av taxonomi och systemstöd för riskbaserad analys inom den svenska Luftfartsinspektionen

The Swedish Aviation Safety Authority has decided to standardise a classification system for reporting deviations found in inspections. The purpose of a classification system is that similar deviations always should be reported in the same way since this will enable better decisions regarding different risk areas. The inspectors are therefore constrained to use a standardised classification system and are not free to use their own words when reporting deviations. A hierarchal classification system with predefined phrases is in aviation referred to as taxonomy. Taxonomy is already in use when reporting accidents and incidents but not when reporting deviations found in inspections.

Det digitala teknikskiftets inverkan på pressfotografer : en undersökning av övergången till digital fototeknik på Bohusläningen

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Filtrering av vatten från Lovisagruvan genom obehandlad respektive järnoxyhydroxidbelagd anrikningssand från Stråssa i syfte att minska halterna av zink och bly

I Lovisagruvan i Bergslagen bryts zink och bly, gruvvattnet (med pH 7-8) är förorenat av framförallt dessa metaller (577 ppb Zn, 341 ppb Pb). Reningen i de sedimentationsbassänger som finns på området fungerar inte tillräckligt bra. I denna studie användes sand från Stråssa (s.k. Stråssamull) som filtermaterial för att rena vattnet. Två olika sorters filtermassor testades, obehandlad Stråssamull (SM) och järnoxyhydroxidbelagd Stråssamull (JSM).

Lärare och bibliotekarie funkar det? En fenomenografisk studie av gymnasielärares uppfattningar om gymnasiebibliotekariens betydelse i undervisningen.

Resource-based learning or problem-oriented learning are teaching methods that are becoming more and more common in schools today. In order to make these teaching methods work there is a demand to make students information literate. This entails that school librarians ought to play a more important role in teaching than before since they are the ones that are the most qualified when it comes to mediating information skills. The aim of this thesis is to find out how nine teachers at six senior high schools apprehend the professional role of the school librarian and how they apprehend the conception of information literacy In order to learn about these conceptions we have chosen to study to what extent collaboration exists in the schools in question and the teachers conceptions of the importance of the school librarian in this context. We have used phenomenography which is both a set of theoretical assumptions and a methodology.

Kommunikativ interaktion i den synkrona elektroniska referenstjänsten : Den interpersonella kommunikationen mellan användare och bibliotekarie

The aim of this master thesis is to gain greater knowledge of interpersonal communication. This study explores on one hand how interpersonal communication can be used as an important part of reference work in a Swedish electronic synchronous reference service, and on the other how interpersonal communication affects the relationship between user and librarian. By using communication theory and establishing a positive relational contact with the user in the electronic environment, the outcome of the reference encounter can be successful for both the librarian and the user. Furthermore, the importance of recognising relational barriers is of great relevance to the relational contact. The scope of this master thesis is to find what relational factors are used and can be used in the interaction between user and librarian.
