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.

Undersökning av bindningsmekanismer vid pressning av metallaminat : Investigation of bondning mechanisms at the pressing of metal laminates

Increased understanding of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments have been studied in detail in the scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and with interferenceprofilometry in Wyko, to provide a greater understanding of the mechanisms that influence the Bonding in the interface between metals. The project was limited to contain the materials Docol 1000, HyTens 1200, Aluminum AA3003 and a commercial steel. The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure.

Charlie och Sara : Narration, heteronormativitet och lesbiskhet i Margareta Subers Charlie

This essay explores the novel Charlie by Margareta Suber (1932) through lesbian narrative theory. The result is a revealing on how the lesbian main character can be established as a lesbian subject against the male and heterosexual narrative; how she escapes a simple male positioning in the narrative, how she subverts categorisation, how she parttakes in female Bonding, and how she disturbs heteronormativity..

Hiphop Edu(N)ation : En kvalitativ studie om relationen mellan skapandet av hiphopmusik och ungdomars socialisation samt identitet

The aim of this study is to explore hiphop music as an aspect of youth socialization and the relationship between music creation and identity. The study is conducted through five semi- structured qualitative individual interviews. Our theoretical starting points are Putnam?s (2000) bridging and Bonding social capital symbolic interactionism. We also have used a model of learning presented by Fornäs, Lindberg and Sernhedes (1989).

Villkor för alliansbyggande med unga lagöverträdare : en kvalitativ studie med socialarbetare om vård i socialtjänstens regi

This study is investigating what conditions can strengthen an alliance and which obstacles there are. Coercion aspects can also influence an alliance and are therefore also written about. The asymmetrical relationship between the social worker and the juvenile delinquent is investigated also with in regards to the tacit and explicit coercion when they are entering care. The study is focusing on the consequence/influence programs that the juvenile delinquents can be sentenced to because of their crimes. Counseling is a major part in these programs.

Socialt kapital i en etniskt homogen förening

This essay is a case-study of an ethnically homogeneous association, situated in an ethnically heterogeneous neighbourhood. The purpose is to examine the social capital of the members in this particular association. The theory of social capital claims that this form of association constitutes an example of Bonding social capital, and is running the risk of becoming excluding towards non-group members. However, several scientists suggest that the ethnically homogeneous associations can assist immigrants in their new home countries to become a part of society, hence promote a more bridging form of social capital. This would be extra valuable in an ethnically heterogeneous context where the phenomenon of social capital often has a hard time.

Systematisk limning av kartong

This report is a documentation of the workflow and the result of a project carried out by twostudents from the Royal Institute of Technology in collaboration with a company. The report isstructured in a chronological order and describes the methods and systems developed in theworkflow.

By conducting a general study about glue and its different forms it was possible to obtain abroad knowledge, which helped to choose the right substances to later use in testing on the differentcardboard materials in question. Glues's survey resulted in a list of different substances that wererelevant to the project.

Civilsamhällets roll i etniska konflikter - hinder eller möjlighet? En fallstudie av Nigerias civilsamhälle

Nigeria är ett av världens mest etniskt mångfaldiga länder. Landet har under senare år, trots ett alltmer demokratiskt styre, erfarit ett uppsving av etniska konflikter. Med en konstruktivistisk syn på etnicitet är orsaken till konflikterna inte given, utan kan elimineras. De nigerianska ledarna har dock inte lyckats med detta, utan snarare gjort problemen än mer komplicerade. Därför syftar denna fallstudie till att analysera civilsamhällets möjligheter och hinder att få bukt med de etniska konflikterna.Genom tillämpande av teorier om inter- och intraetniskt civilsamhälle samt socialt kapital finner vi att civilsamhället, som genom en bred definition är livfullt och heterogent i Nigeria, i dagsläget är för svagt och fragmenterat.

Forskningsbiblioteket som mötesplats : En ny sida av forskningsbibliotekets uppdrag?

The purpose of this thesis is to investigate how the research library of Linnæus University is used by students as a meeting place. Building upon Putnam's theory of Bonding and bridging social capital and Audunson's conception of high and low intensive meeting places, it aims to explore the research library's potential for creating social capital and thus strengthening both learning and democracy in a university context. Borrowing part of the survey design from a study conducted as part of the Norwegian PLACE project, this study collects responses from 134 students as to their use of the library as a meeting place. The results show that the Linnæus University library is used for a variety of meetings of both high and low intensity, why it should provide a good setting for the creation of social capital. There seems to be a connection between how often one visits the library, as well as to which department one belongs, and how one uses the library as a meeting place.

Kroppstemperatur och vattenavdunstning via huden hos extremt underburna barn vid vård i kuvös och med kängurumetoden

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

Ett designprojekt med fokus på för tidigt födda barns emotionella behov i kuvös

Babies born prematurely are deprived of normal sensorimotor stimulation when placed in an artificial environment, the incubator. The aim of this project was to design a series of products that could promote the baby?s emotional and neurological development, and to facilitate parental Bonding. The products designed in this project has a theoretical basis on the research available today on cognitive and emotional development in children born prematurely. They were developed in close cooperation with a group of parents and nurses in a neonatal intensive care unit.Presence is a product collection for developmental care, consisting of a mattress, a figure and a necklace. The mattress has vibration sensors that transfer the mother?s heart beat and speakers with recorded heartbeat and her voice.

Husby Marathon : En studie av projektets betydelse för ungdomars sociala kapital ochsjälvidentitet
