Analys av fördelningssystem för bostadshus

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

Enabling Smart Research and Development through Knowledge Conversation

Abstract Title: Enabling Smart Research and Development through Knowledge Conversation Seminar date: 2005-06-08 Course: Master thesis in business administration, 10 Swedish credits (15 ECTS) Authors: Andreas Johnsson, Johan Rosendahl Advisors: Lars Bengtsson Key words: Knowledge management, Knowledge conversation, Research and development, Ba, Trelleborg Purpose: The purpose of the thesis is to create a model that shows how knowledge management aimed at research and development processes can be used and how the theoretical fields can be connected. Methodology: The thesis is based on abductive perspective where empirical and theoretical material has been mixed to create a foundation for the analysis. Theoretical perspectives: Theories concerning knowledge management and research and development have primarily been used. These have been complemented with material about team structures and incentive systems. Empirical foundation: The empirical material is based on semi structured, mostly qualitative interviews and strictly quantitative inquiries performed at Industrial Hose within the Trelleborg group.

Om vägen till ett bättre bestånd vid ett skolbibliotek ? en aktionsforskningsansats.

For a school library to function as a support for the students? development of their academic abilities, it must provide material satisfying their needs as well as the needs of the teachers. The school library should assist the students in their research endeavours, as well as inspire reading for pleasure. In order to do this it is imperative that the school library actively develops the existing collection and continually strives to meet the needs of its users. The aim of this Master?s thesis is to describe and reflect upon how a particular school library works with collection development.

Mark röjd från sten : En studie av förklaringar och tolkningar kring röjningsröseområden

AbstractThis essay discusses different explanations and interpretations of what characterizes large areas containing clearance cairns (cairn fields). Results from the analyses show that there are different explanations about when and why cairn fields and clearance cairns occur. Explanations vary from introduction of the wooden ard in the early Bronze Age to the introduction of rational hay-making in the Roman Iron Age.  There is, anyway, relative agreement considering why and when cairn fields were abandoned. The reason suggested is an increasing pasturage with the consequence of reducing soil to poverty during the period of the Great Migration or in the Viking Age.The most likely cultivation system in cairn fields is a system consisting of both intensive and extensive characteristics. The latter coincides with the probable mobility of settlements.

Vad är syftet med läxor? - Vad anser pedagoger och elever om läxor?

Syftet med examensarbetet är att utveckla en förståelse för läxor i en årskurs sexa. Vi vill ta reda på antalet läxor som eleverna i en klass kan få, men även ta reda på vad själva syftet med läxorna är. Vi vill fördjupa oss i om pedagogerna och elevernas uppfattning om läxor ger stöd för lärande. Nedan presenteras vår frågeställning till examensarbetet. ? Vad är syftet med läxor? ? Hur många läxor får en elev i genomsnitt i veckan enligt pedagogerna och eleverna? ? Vad anser pedagogerna och eleverna om läxor? ? Vad är pedagogernas och elevernas uppfattning om läxor ger stöd för lärande? I teoretisk bakgrund har vi valt att ta upp om tidigare forskning angående läxor och vi har även tagit upp tre olika teoretiker: Vygotskij, Piaget och Gardner.

Mätning av abrasivflöde för vattenskärningsmaskiner

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

LÄXOR Ett arbete värt sitt resultat? En studie över några lärares syn på läxor som pedagogiskt redskap

Syftet med denna uppsats är att studera några lärares syn på läxors funktion och paktiska tillämpning. Uppsatsen bygger på en litteraturstudie och på kvalitativa intervjuer med sju lärare i årskurs 1-3. De frågeställningar som ligger till grund för uppsatsen är: vad anser ett urval av lärare att läxor ska ha för funktion, hur utformar dessa lärare läxor och hur menar dessa lärare att läxor ger effekt? Resultaten som framkommit i undersökningen visar att läxor ingår som en naturlig del av undervisningen hos de lärare vi intervjuat. Läxorna förekommer med varierat syfte och med skillnad i dessas utformning.

Vad är lantbrukarens syn på länsstyrelsens djurskyddskontroll?

Indications on poor understanding for the animal producers situation from the inspectors of animal welfare control have been seen in papers from farmers interest organizations. The aim of this study was to investigate what farmers view is on the animal welfare inspections done by regional Swedish authorities as well as the animal welfare inspectors work. The study investigated whether or not there were any differences between different counties in Sweden. There were also questions asked to see what animal producers thought could change in the animal welfare inspectors work so it would benefit them. The study was conducted using a telephone interview questionnaire.

Förhandlingar om när, var och hur läxor ska göras - inte om de ska göras : En diskursanalys om elevers uppfattningar om läxan

Idag är debatten om läxor vanligt förekommande i såväl skolans sfär som i media och inom politiken. Dessa debatter kan ses som ett sätt att skapa en normalitet, och en strävan efter att få fler att ansluta sig till de olika parternas uttalade uppfattningar om läxans förekomst. Tillsammans med denna debatt utgör läroplanen några av de normer som skolans aktörer ska förhålla sig till gällande läxorna. Trots att läxan inte nämns i läroplanen så lever läxan vidare och vi väljer därför att betrakta läxan som en norm, som följs av inte bara skolans aktörer och eleverna utan även av föräldrar. Även fast läxan i huvudsak berör eleven anser vi att elevernas talan om läxor inte representeras i de debatter som förs, och vi undrar därför; var är elevernas talan om läxor?Vi har därför valt att anta ett elevperspektiv och använder oss av en diskursanalytisk ansats för att förmedla deras uppfattningar om läxor.

Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

August Strindbergs arkiv från privatarkiv till kulturarv: En studie i proveniensprincipens tillämpning och nationalistisk historietolkning.

In this thesis I examine the events that followed the death of August Strindberg and resulted in his private belongings becoming an important part of Swedens cultural heritage. My purpose has been twofold: firstly, to identify which aims were sought to be achieved when dealing with Strindberg's archives and his home and to relate these to a nationalistic interpretation of history, secondly, to relate this work to the then newly introduced archival principle, the Principle of provenance. I identified three different aims: firstly the economic aim must be seen in the light of an increasingly expanding publishing market. I argue that the author gained a new and important role in the general social debate a nationalistic one, an important point with regard to my following conclusions. Secondly, the aim to store and display the material in a museum is discussed in relation to different views of cultural history and the interpretation of history.

KYRKLIGT KULTURARV I BEREDSKAPSPLANERING Logistik, roller och urval

With the political situation that prevails in the world, the need for contingency planning for the ecclesiastical heritage has become actualized with the aim of protecting the churches and their assets in war and armed conflicts. In accordance with Kulturmilj?lagen (SFS 1988:950) chapter 4 ? 15a, the Church of Sweden and its organizational parts are responsible for ensuring that contingency plans for the ecclesiastical heritage are established. In the legal statutes, it is not clear how this is to be carried out, who is responsible for all practical aspects or what is to be protected, something that creates gaps of knowledge regarding logistics, roles and selection. This means that there is currently a lack of principles and practice around the protection of the ecclesiastical cultural heritage, as contingency planning for cultural heritage is a fairly new phenomenon that has not been practiced in times of peace.
