Skotares bränsleförbrukning :

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Renoverings strategier på befintligt fastighetsbestånd?fyra fallstudier om allmän nyttiga fastighetsbolag

Today  Real  estate  companies  face  the  challenge  where  extensive  renovations  on  existinghousing built before 1980 must be performed. Conditions have changed and the housing need performance-­?enhancing measures that meet today's quality. With a current renovation rate,  it  would  take  30  years  to  meet  the  renovation  needs.  The  renovation  rate  must therefore rise dramatically, which requires the real estate companies to act consistently in accordance with commercial principles and in an economically, socially and environmentally responsible way.The  paper  discusses  renovation  strategies  in  four  municipal  housing  companies  in  the Stockholm  suburbs.  The  report  includes  surveys  of  four  ongoing  renovation  projects; Fastighets AB Förvaltaren in Sundbyberg project Hundloken 3, Stiftelsen Signalisten in Solna project Ritorp, Sollentunahem in Sollentuna project Svalgången och Väsbyhem in Upplands Väsby project Dragonvägen. The main purpose of this study was to analyze the practices of redevelopment projects.

Synen på de hemlösa och deras livssituation : - en kvalitativ studie

AbstractThe intention of our study is to examine how the view of homeless people and their life situation looks according to a selection of persons, which in their work get into contact with homeless people. The study is based on a qualitative method that includes interviews.The result of the study is based on interviews with eight persons working in the social services, volunteer organisations, the police and a security organisation. The majority of the persons that have been interviewed are normalising homeless people; they do not look upon them as different. At the same time they have the opinion that homeless people live a tougher life and that they have to fight more for their living than other people. The persons that we have interviewed share the view that homeless people live under a constant pressure of finding a place to sleep.

Biblioteken och 2.0. En idéanalys av synen på den sociala webben i några skandinaviska bibliotekstidningar.

In this thesis we have examined opinions of the social web in Scandinavian Library journals. Our interest lies in aspects about the social web, and above all about Library 2.0. The central question is how this new technology, a growing digitalization, and a social web that focuses on interactivity and participation affects opinions about libraries. We have investigated opinions about Library 2.0, with respect to three different dimensions: The role of the library in society, power/hierarchy and knowledge. The method used in this thesis is idea analysis using these dimensions as analytical instrument.

Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

Ut ur hedersförtryck : En studie baserad på sju självbiografier skrivna av kvinnor som levt under hedersförtryck.

The aim of this study is to understand which strategies helped women escape honourbased violence, by reading the autobiographies of seven women. Honourbased violence is a relatively new problem in Sweden, but it has existed for a long time. According to FN (2012) 5000 women are murdered every year in the name of honour. Honourbased violence is about maintaining the honour of the family. Womens sexuality is connected to men´s honour, and because of that they are not allowed to express it.

Stolthet och fördomar: upplevelser av hur det är att vara ung i Herrgården

The purpose of this essay was to investigate the experience of being young and living in Herrgården in Rosengård, Malmö, from the aspects of six adolescents, two police officers, one social worker and one youth leader; and also what the cause is according to them, of disturbances arousing like those in the spring of 2007. At this moment there were antagonisms between adolescents and policemen. The research was performed with a qualitative method based on partly structured interviews. Four kinds of main themes were notable from the interview results. Those were: Growing up in Herrgården, Other peoples' view of Herrgården, Identity and Causes of the disturbances.

Säkerhets- och arbertsmiljöarbete på Arbetsförmedlingen : Naturlig utveckling och påtvingade förändringar

Arbetsförmedlingen is the Swedish national authority responsible for the work politics, and its main purpose is to create and build a solid and sustainable job market.Economic crises together with changes in the society and in the organization over the past few years mean that the unemployed individuals that come in contact with Arbetsförmedlingen are no longer a homogenous group. A lot of effort is put into helping those who may find it difficult to enter the work environment, such as youths (19 ? 26 years old), people who have been unemployed or on sick leave for a long period of time, people with disabilities or immigrants who are newly arrived in Sweden.A harder social and economic climate can lead to frustration among the unemployed which mean that security measures at the offices has had to become adjusted. Local offices now have a public area where they have meetings with their clients and a locked open plan office space to which the public have no access. Working within an open plan office environment can cause health problems, mostly due to the constant background noise that comes from people having conversations on the phone, or with each other.

Skolan i universum - att förklara det ofattbara : Astronomiundervisningen i skolan på 1900-talet

This is a study in how astronomy has been taught and is being taught in Swedish schools from 1905 to this date with an emphasis on the latest 30 years. It concerns the regulations and methodical recommendations/curricula for Swedish junior high school/Swedish Comprehensive school for the years 1905, 1933, 1955, 1958, 1962, 1969, 1980 and 1994. The matter of integrating astronomy with other subjects and different methodical approaches is also considered. The problem with textbooks written only for one subject when the teacher tries to integrate subjects is emphasised.Physics textbook analysis shows that astronomy teaching has over the years developed, from being based on observations, to become more and more theoretical. It also shows that the amount of practical exercises has been fairly constant in physics textbooks during the seventies end eighties but now in the nineties varies a lot from textbook to textbook. The amount of liberty the textbook gives the pupil in finding knowledge and answers himself in the practical parts of astronomy was at its lowest during the seventies.

Avskaffandet av revisionsplikten : Vilka alternativ till revisionsplikten föredrar småföretagarna för att upprätthålla trovärdigheten?

Purpose: The purpose with this study is to see what the small limited companiesprefer of the alternatives to the statutory audit that has been created inthe others EU-countries. These alternatives can be current in Sweden tomaintain the credibility.Method: Quantitative procedure.Conclusions: By the result to judge from the small limited companies prefer the alternativeto the statutory audit where they do not need to hire further helpto complete the audit. That is probably why the bookkeeping agency hasbeen chosen to give a guarantee for quality endorsement..

Kostnadskalkylering på en förpackningsavdelning

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

"Sist in - först ut" : Hur turordningsreglerna förhåller sig på den svenska arbetsmarknaden idag?

Abstract The subject of this thesis is the priority rules that apply in connection with mining activity. Already back in the 1800s, there were rules in the so-called Lego Charter concerning protection of workers, mainly servants. When the first modern trade union was founded in the 1870s, also developed a collective agreement. These agreements were the order of priority clauses had to intend to ensure employees' working lives. Exceptions had to be done by ensuring that individual employees' dependents. In 1974 the Act on employment entry and had intended to protect older workers.

Stenmaterial vid asfalttillverkning

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Selånger deltapark : Sundsvalls nya stadspark - en vision

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.
