Man kan ju inte gå klädd hursomhelst : En studie om hur högstadietjejers identitet
To understand students, their world and what makes them act in a certain way or how they form groups in school is a very important part of a teachers work. You get a better understanding for the students behavior by having knowledge about how they look uponthemselves and other students, to prevent prejudice and tendenses to bullying and beeing an ?outsider?. Clothes and fashion are often a big part of the students identity buliding and how they look upon themselves and get looked at by others.We have chosed to exeminate this phenomenon among girls since they are often more exposed by the media for example and with unreasonable beautyideals and other external factors that many girls try to live up to in todays society.We have made a survey regarding the usage of clothes and fashion in the making of an identety with totally fiftyeight girls in the ninth grade on two different public schools in Haninge and Tyresö municipality..

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..
Amfibier i nyanlagda våtmarker : En fältstudie i Laholms jordbrukslandskap
Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.
Site fidelity of a migratory species towards its annual range
Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.
Potentiella virala zoonoser hos apor på svenska djurparker år 2008
This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.
Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön
Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.
Natura 2000: en rättsfallsanalys
Natura 2000 som områdesskydd för arter och habitat har vuxit i betydelse
sedan införandet av Habitatdirektivet (92/43/EEG) och direktivet om
bevarandet av vilda fåglar (79/409/EEG). Det är därför intressant att se hur
EU försöker bromsa utdöendet och habitatförstörelsen genom dessa lagrum. En
del i detta är de avvägningar som domstolsväsendet genomför vid exempelvis
exploatering av Natura 2000-områden. Dessa rättsfall är intressanta att
studera eftersom det inte räcker med korrekta lagregler för att skyddet av
arter och habitat skall bli fullständigt, utan det kräver även att rätt
ekologiska och juridiska avvägningar genomförs i domstolarna. Syftet med den
här uppsatsen är alltså att undersöka de juridiska och ekologiska faktorerna
i rättsfall som handlar om Natura 2000.
De rättsfall som har analyserats för att undersöka hur domstolarna har
tolkat lagreglerna och de ekologiska faktorerna är M 5388-03 om Hagöns
naturreservat, M 6581-05 Minivattenkraftverk vid Ljungån, C-127/02
hjärtmusselfiske i Waddenzee och C-355/90 Santona-våtmarkerna.
Utifrån ett miljöperspektiv har domstolarna en viktig roll som beslutande
myndighet i till exempel tillståndsärenden och har möjlighet att besluta om
en viss miljö skall exploateras eller inte helt beroende på hur de ser på
miljön som beslutet rör.
Hot och våld i socialarbetares yrkesutövning : Threats and violence in the socialwelfare secretary occupation.
2004, the SSR, Akademikerförbundet, made a study on the threats and violence as a social secretary in the municipal social services are exposed in their occupation of the "social secretary of threats and violence at work" (T-110192), conducted by Temo ab. We have chosen to use the study on a smaller scale and then made contact with five municipalities in the middle of Sweden to investigate social secretaries experiences of threats and violence. Using the cross-sectional design and a convenience sample, we have gained access to data from 56 people. From a sociological perspective, we have chosen to use Norbert Elias theory of universal configuration and interdependence, and Michel Foucault?s theories concerning power search explanation for the existence of threats and violent situations in the contact between social workers and their clients..
Riskbedömning vid Saltvikens kopparverk
AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.
Professionalisering : Föräldrars åsikter om en organisationsförändring av den svenska barnidrotten
The Swedish way to organize sport has a long tradition and the parents play an important role in ways to organize sport. Without the thousands of adults who voluntary work the sport associations would have problems to survive. However, there are tendencies to that commitment is reduced, which means that the activity is exposed. The purpose of this study was to examine parents opinions about a nonprofit children´s sport respective professional children´s sport. The study was based on questionnaires which were distributed to 83 parents in four different sports; equestrian sport, track and field sports, ice hockey and soccer.
??då hör inte jag hemma hos er!? : - Att ta avstånd från en religiös gemenskap
This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.
Strokediagnostisering på akutrummet : Är standardiserade scheman användbara i strokediagnostiseringen samt anamnesupptagandet?
Amyotrophic lateral sclerosis is a progressive neurological disease which causes a slow degeneration of the body. Living with this disease means being exposed to severe strain and every day could bring new losses. Amyotrophic lateral sclerosis does not cause any harm to the intellect, the mind remains unaffected. The aim of this study was to achieve an understanding, and to shed light on the nature of positive life experiences of people living with amyotrophic lateral sclerosis. This literature study is based on detailed examination of three person's narrations taken from their autobiography and biographies.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

Innovation på Itkonsultföretag. En fallstudie på EVRY
Companies today are exposed to a turbulent market with fierce competition and the ability toinnovate itself becomes increasingly important. But what innovation is and how it is managed is farfrom obvious. In this case study at EVRY the research questions are: ?What is innovation in ITconsultant companies?? and ?how can innovation be managed in IT consultant companies?? ITconsultancy is a complex type of business and their focus is often to innovate the customers businessrather than their own. The study is based on a literature review, field studies, unstructuredinterviews and an interpretive analysis.
