Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874
The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.
Mätdatainsamling
Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

Analys av lageregenskaper utifrån mätningar i testrigg
Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.
Ett universitet med eller utan cannabis? : En kvantitativ studie om utbredningen av cannabis vid Linköpings universitet och huruvida det finns något samband mellan cannabis-användningen och studenternas upplevelser av studiesituationen.
Cannabis är den mest använda drogen i världen och attityderna gentemot den blir allt mer liberala. Då många syntetiskt framställda cannabinoider ständigt dyker upp på marknaden visar studier på olika resultat angående utbredningen av drogen. Det är personer i de yngre åldrarna som i störst utsträckning använder cannabis. I dagens samhälle ställs det allt mer krav på unga vuxna, inte minst när det gäller att skaffa sig en utbildning. Syftet med denna studie var därför att undersöka om det fanns något samband mellan användningen av cannabis och upplevelser av studiesituationen bland studenter vid Linköpings universitet.Studiens teoretiska utgångspunkt utgjordes av Robert K.
UTFACKNINGSVÄGGAR : En jämförelse mellan platsbyggda och prefabriceradebyggmetoder
In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.
Injuries associated with climbing: a questionnaire study
Background: During the last decade climbing has become more popular and the numbers of climbers in Sweden have increased considerably. Most common are overuse injuries caused by the great stress and strain climbing creates on different parts of the body. Previous studies show that 75-90% of climbing injuries are localised in the upper extremity. Injuries affecting the lower extremity occur often acute and traumatic. Based on these facts and that the number of climbers constantly grows, it is more likely that the need of care from physiotherapist among climbers will increase.
Wii Sports och Sport : En jämförelse av fysiska och emotionella skillnader och likheter i träningsspel jämfört med riktig träning
AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.
Lyfta Lätt Tekniskt hjälpmedel för pakethantering
People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
Att lyckas när oddsen talar emot : Hur lämnar man gängkriminaliteten-den enda gemenskapen?
The purpose of this study was to create a deeper understanding for, and shine a light on the exit process for former criminal gang members. Which conditions appear to be important and what may constitute the enabling and inhibiting factors of an exit process? The study was based on qualitative semi-structured interviews with respondents who themselves have experience of a criminal lifestyle and gang affiliation, and with professionals in social work. Our theoretical approach is based on Helen Ebaugh?s definition of an exit process, labeling theories, strain theory and control theory.
Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage
When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.
Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.
A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
Bryr sig företagskunder om leverantörens corporate image? : Betydelsen av leverantörens corporate image vid köp av kunskapsintensiva IT-konsulttjänster.
Background: Critical conditions to become an attractive supplier of knowledge based IT-services in the B2B market are many. Besides the fact of supplying a service of high quality one must as a supplier communicate values which are understandable and desirable for a new buyer. Buying a knowledge based IT-service involves several risks; the consultant might not have sufficient knowledge or have difficulties understanding the corporate culture and collaborating with other staff within the client?s organization. Since services are intangible offers and it can be intricate to put right price level for something which can only be evaluated when the project is finished, puts severe strain on suppliers competing with other companies in the same market when looking for new clients.
The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems
Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
