En studie av höghusbyggande med avseende på stomsystem och lastpåverkan
Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.
Entréträdgårdar - rumslighet, gestaltningselement, uttryck och sociala aspekter :
The BA thesis Front Yard Gardens ? spatiality, design elements, expression and social aspects is a summary of the entrance and front yard garden phenomenon ? where the entrance is the set design and the designer is the director. The thesis touches the social context of which entrances have been and still are shaped. The various appearance of the entrance and front yard gardens throughout the history, starting with the first entrance by the edge of the wood and coming up to the front yard gardens of today, is described. It touches the present day through an analysis of some entrances and front yard gardens of modern residential areas.
Analys och kontroll av hållfasthet på grenställsarm
The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus
That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.
Incitament för fastighetsägare att omvandla bruna kontorsfastigheter till gröna - När och varför de väljer att investera
This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
Exosomes as a potential mechanism of intercellular spread of prion protein
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Porträttering av förorten Tensta
The purpose of this study was to investigate hove some suburban areas image is shown to the public in the media coverage of suburban areas, and this is why I in this paper want to look more closely at the image of Tensta in the news media and how people in Tensta perceive themselves. News media has a very important role in the creation of human worldview. It influences our own identity and affects what a person believes is the difference in us and them. In the post-colonial theory, identity creation is a central role in philosophy, us and them. Based on the above purpose, I formulated an overall main question that this essay should answer.
Intendenturpersonalens syn på säkerhetsarbetet ombord på ett passagerarfartyg i färjetrafik
Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.
Utveckling av en produkt som förenklar koppling av släp
This thesis was conducted at SverigeGrepen in Vänge-Körlinge, Uppsala, Sweden.SverigeGrepen is a family business that develops and manufactures a few different parts of different kinds of products. My task is to come up with a good idea that facilitates the coupling of trailers, i.e. from an idea to a fully functioning prototype. The product is intended for use by all customers for all kinds of trailers. The actual goal of the work is to develop a full prototype that you can install and use in the easiest way possible, a prototype that follows the specifications.
Barns rättigheter - en självklarhet?
Numerous studies have showed that Swedish municipalities are responsible for several of the activities that concern children and their rights, e.g. school and health care. Furthermore, the Convention of the Rights of the Child is an international agreement that Sweden has signed and ratified which also implies the obligations that Swedish municipalities have. The purpose of this study is to investigate and compare, from a social justice perspective, how children?s rights are being emphasized and how children?s opinions are being taken into consideration at the municipality level in Sweden.
Ungas avhopp från kommunfullmäktige : En studie om unga fullmäktigeledamöters beslut att lämna sina uppdrag
Young councillors are currently under-represented in Sweden's municipalities. Young councillors are also stepping down in greater numbers than older members. This paper explores the reasons why young councillors choose to resign from their mission, so to identify possible remedies to the problematic trend of underrepresentation of younger people in local authorities in Sweden.This qualitative essay intends, through interviewing politically-active young people who has left their assignment, to study the reasons for resignations from elected posts. To see what could be the reason I have looked at previous studies and theories about opting out but also tried to remain open to identifying new and emerging trends previously undetected in existing surveys.The results showed that the political assignment proved to be too time-consuming, with young people choosing to spend their time on career and leisure. Those who resign from political life often express criticism towards the Municipal Council; they consider it tedious and many complain of having little influence.
Notes Towards a Mental Breakdown : det teknologiska traumat i J.G. Ballards The Atrocity Exhibition
This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system.
Fader Vår : om fäder med intellektuella funktionsnedsättningar
Most studies on parenthood and learning difficulties focus on mother and child, and very little is know about fathers with learning difficulties. Moreover, people with learning difficulties are rarely asked to tell their own narratives. The aim of the current study is to identify the role of the father in families where one or both of the parents have learning difficulties. Laws and regulations concerning the rights of people with learning difficulties in Sweden are accounted for and the he social support system for all parents in Sweden are described .The empirical study is a qualitative phenomenological interview study, inspired by narrative traditions, and describes how fathers with learning difficulties experience these support systems. The main data are two life stories of fathers with learning difficulties and one observation in a family.The findings suggest that although Sweden has a highly regarded disability policy and social support system, and even though fathers with learning difficulties are assured equal rights as members of the society and as parents by the Act of Human Rights, they are not treated equal but still faces structural inequalities.
Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.
"Periodare" hos socialtjänsten? : En undersökning om unga vuxnas behov av försörjningsstöd
The purpose of this study is to find out how social workers in one medium and one smallmunicipality in central Sweden perceive the need of financial support for young adults formore than one year and what the causes might be. To answer our research questions aqualitative research method was used and four social workers were interviewed. The resulthas been analyzed based of social exclusion, stigma, as well as on structural and individuallevel and linked to previous research. Our results show that although young adults are anexception for long duration for financial support, there are those who lack other means ofsupport for a long time. The results also show that young adults often are recurring in thesocial services, and they are long-lasting.
