Trygghetsskapande design av Mörby stadspark :

The purpose with this thesis is to investigate how to design a urban space so that it is experienced safe and how to implement this at an actual site. Knowledge on the subject has been gathered through litterature studies and interviews with experts. Through an analysis of the site with surroundings and studies of projects with similar problems, practical actions have been observed. Part taking in the municipalities planning process has given insight in the projekt as an whole and the interests of different parties. There are many different opinions about what the word safety means. It is a feeling depending on situation, that is affecting our daily behaviour.

Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län

Burnt alun shale and lime is the residual product that was formed when alun shale was used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium, molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale and lime to determine whether or not the surrounding environment and humans are exposed to these elements by eating plant products. A cultivation trial was carried out where onion, carrot, and lettuce were grown on three mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a reference soil. The reference plots were natural soil mixed with peat adjacent to the mounds.

Utfodring av rapsfoderråvara i fodersystem till mjölkkor

The feed is a major cost in the dairy production and there is a constant interest in findingalternative cost-effective feedstuffs. Competitive dairy producers have to seek ways todecrease their production costs and the pursuit of cost-effective feed rations contributesto lower costs of production. An interesting group of protein concentrates are rapeseedproducts like ExPro (heat treated rapeseed) which have during the autumn 2008 andspring 2009 been very favourable compared to other protein feeds.This study focuses on the feedstuff products ExPro and Raps-Drank 60/40 (rapeseeddistillersgrain). The potential use of ExPro in dairy cow feed rations are also explored.ExPro is a well known feedstuff but Raps-Drank 60/40 is a relatively new product andnot known for many farmers.A field study on the use of rapeseed products was made on a limited number of dairyfarms. The main purpose was to study the management of the feedstuffs on the farms.The Farms were selected in cooperation with two local extension services.

Emotionella sprickor och utbrott - i en sorg

Intangible feelings of sorrow and grief, caused by events like separation, death, loss and trauma, all leave some kind of traces in us and they play an important role in our development. The individualistic society here in Sweden has shaped us to keep our feelings inside and at bay; since our childhood we have learnt that showing emotions like tears, sorrow and sadness are signs of weakness and can make others and yourself feel uncomfortable. With the starting point from my own experience and understanding of how we can deal and handle grief, I take a closer look on how jewelry, objects and rituals can be of importance in a grieving process and our lack of visual outer display of grief in today?s society. Through Sara Ahmeds theory I found a new possible way of understanding emotions and how they shape us.

Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

Det fria valet av gymnasieskola? En studie av informationskanalernas betydelse för valet av gymnasieskola

The free choice of upper secondary school?A study of the meaning of the information channels for the choice of upper secondary schoolAuthors: David Fridner & Rikard ZeilonMentor: Ingela WadbringQuestionnaire studyDate: 2008-08-11AbstractThe choice of upper secondary school is a very important choice, both for the school and for the ninth grader. In Göteborg, the free choice of upper secondary school has generated several new information channels apart from the traditional counselor, daily news and the acquaintance. Today it is harder than ever to reach the pupil through the constant media noise and new forms of communication such as events appear. The fight for each pupil gets more and more important every term and it has now become real big business.Today?s youth is imprinted by a growing individuality and everyone knows that equableness is something very important.

Konstruktion av patientsimulator för anestesimaskiner

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

Enklare korglutning

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Bankernas bedömning av lantbrukskrediter : en jämförelse mellan olika branscher

The agricultural sector has historically seen stable prices and a relatively constant demand for its products. Companies within the sector have generally had few loans and large sums of money tied in assets. The profitability of the companies has on the other hand been low. Together these circumstances have determined the creditors? demands on the companies within the sector and have formed the rules and regulations that exist today.

Birgitta - Helig eller helgalen? : Kan Birgitta Birgersdotters mystika gudserfarenheter ha sanningsanspråk?

Prisons are for many an unknown world, and few know about the prison culture which includes unwritten rules, power structures, interactions and relationships between inmates and correctional employees.While many think that Swedish prisons are too comfortable,inmates are facing extreme stress due to surveillance and detention, by depriving inmates their possibility to shape their own lives. When the inmates is deprived of control over their own life?s the penal system have great power to shape and to influence the inmates.The purpose of this paper is to investigate prisoners' experiences of treatment and exercise of power in prisons. Starting point is to examine what are the kinds of relationships between prison officers and inmates from a power perspective, if there is any difference between the closed and open prisons and how the inmates affected by the structures that exist.Based on my overall purpose, and with my informant´s stories which revealed a number of similar points, four main headings were developed; Mass media and society´s view, and unknown world, interaction between inmates and prison officers and consequences.Prison officers with the role as a contact persons as well and other staff which work close to the inmates play a significant role by supporting through motivational interviewing and can help the inmates to gain insight about their life situation and actions. My informant?s underlined that a good contact person can either help or discourage.Inmates who contributed with their experiences express that there is a big difference between open-and closed prisons.

Socialt stöd, krav och kontroll den psykosociala arbetsmiljön på ett bemanningsföretag

AbstractComing to new job is not that easy, sometimes the feeling of insecurity appears. Working for recruitment agencies includes constant changes of colleagues and places of work and at the same time one has two different managers. Who does the individual turn to when problems occur and who do the employed see as his/her manager? Why do people search for work in recruitment agencies? How does it feel not having a fixed place of work or colleagues and how do the aspects of this affect the employed psychosocial work environment? This is a few questions asked when we tried to find answers on the employed feelings about his/hers psychosocial work environment in a recruitment agency. The purpose of this study was to find a deeper understanding on employees working in a recruitment agency experiences their psychosocial work environment on the basis of social support, demands and control.

Dammet, vår minsta gemensamma nämnare : En känsla av tillhörighet

Dust, our smallest common denominator                                                                                                                                                                 Charlotta Lindvall ABSTRACT  I find it fascinating to know that we are all made of the same material as the stars and that everything is connected to each other and in a constant movement and transformation, a recycle of material. We are all made of stardust. In fact all life is sprung out of dust.In my essay I investigate the dust and ask the question if there are any traces in the dust. I look at the history of the dust and how it has affected us and our world through the decades. What does this small and airy but oh so unappreciated dust tell us? Why do we want to get rid of it? Is it possible to find a sense of belonging in the big context by investigating the dust and its origin and could I transform such a low material as dust into something magic that makes people reflect on our origin and belonging and how everything is connected? In my work I use dust as a material and in the essay I compare my work with other artists who have worked with dust as a material.Dust is everywhere because its source is from everything.

Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Försvaret i skolan : En studie om total- och civilförsvarundervisning i skolan under 70-talets kallakrigsår.

The purpose of this essay is to illustrate the preparation of total and civil defense education in schools in the 1970s to gain insight into how the school looked and pondered the complicated world that existed outside the school's doors. By using the concepts of welfare state, welfare and civil defense culture, I have studied relevant materials to get answers to questions treating the total and civil education in schools after Lgr69, the way the state sees the subject and if it is possible to detect a civil defense culture in schools and if so, how it will be expressed.     The results show that the state emphasized education as incredibly important because knowledge of how to act in a crisis or war could be extremely crucial for the individuals and their survival. The education was so important that it got a role as a main factor in Lgr69. But even if the education was important the teachers had huge problems with the schedule and many teachers couldn´t educate all facts because they didn´t have enough time.

Blandfoder i automatiska mjölkningssystem

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.
