Broms- och styrsystem för möbeljalusier
This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.
Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Strömmar av vatten och politik - en studie om policyprocesser och anpassning.
One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.
Biodling i Stockholms stadskärna : Ekonomi, ekologi eller ekosofi?
Previous research confirms that there is a major decline of pollinators worldwide. Investigations have mainly focused on pollination services in the agricultural landscapes and therefore, there is a lack of knowledge on the effects pollinators may have in urban environment. This paper examines the presence of honey bees in central parts of Stockholm, Sweden. The study presents what conditions, possibilities and motives there are behind the phenomenon of urban bee keeping. I found ten locations with beehives and a total of 18 hives within the delimited area. Nothing seems to indicate that conditions may limit the presence of honey bees.
Djuromvårdnad vid fång
Laminitis is a common but devastating condition, and affected horses are often euthanized or influenced a very long time. Many horses never return to their original capacity. Laminitis is often associated with severe pain and a long time of convalescence. Symthoms includes lameness, hoof hyperthermia, strenghthened digital pulse and pain. The horse often tries to move the body weight away from the forelegs which are often more severly affected than the hindlimbs.

Den svenska neutralitetsdebatten 1988-1992
Starting at the end of the Cold War, this publication assesses the impact of the upheavals in Eastern Europe and the atrophic Soviet Union on the Swedish doctrine of neutrality with its 200 year old tradition. Since the end of world war two the proximity of the Soviet Union had constituted the major impetus for upholding a position of neutrality and as this vanished a pressure for change was created. This essay works with a theoretical framework delineated by Kjell Goldmann and under this disposition, the Swedish tradition of neutrality, governmental positions, opposition and four major influential newspapers are studied. The standings of each variable are canvassed in an attempt to explain the development of Swedish security policy during the crucial years of 1988-1992..
Hur påverkar ny teknik företags relation och kommunikation mot sina kunder och leverantörer?: En studie av fyra företags utnyttjande av moderna affärssystem och effekterna i kund- och leverantörsrelationerna.
This qualitative case study, made with four companies, looks closer at how more effective information management, with the help of IT-systems, affect companies market communication and relations to customers and suppliers. Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..
Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation
The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..
Mode en gråzon? : En studie av modebranschens position mellan konst och kommers
The purpose of our essay is to develop an understanding and an insight for the fashion industry. We want to examine what the creative industries can learn from the unique position that fashion hold in a field between commercialization and art. We used a theoretical ground to enlarge our understanding for the distinctive place that fashion holds. To gain further insight in the fashion industry we complete the theory with empirical facts. The empirical facts were collected through a qualitative method with deep-going interviews.
Teknik för vårskörd av hampa till stråbränsle :
Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops.
The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.
Dragbrotschning av invändiga profiler
High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.
