Golvskyltens oanade effekter - En studie om golvskyltens outforskade effekter
Floor signs in stores have become a more common phenomenon during past years. The problem is that the knowledge about these signs is limited and the actual effects are unknown. This lack of knowledge can have a negative impact on store performance and marketing efforts. The purpose of this paper is to examine the effects of floor signs on consumer attitude and behaviour. The study was conducted in two grocery stores, where the movement pattern of 39 501 customers was recorded over a four week period.
?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans
Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.
Värmning av avloppsvatten med spillvärme för att förbättra kvävereningen -Temperaturens inverkan på kvävereningen
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
Lönsamhet i svenska banker - En tidsserieanalys av de svenska storbankernas lönsamhet och risktagande
This study aims to scrutinize the four major banks in Sweden on how their profit havedeveloped over a time span of 15 years, whether stricter regulations have had anyimpact on financial key ratios and if there is any correlation between the banksprofitability and their risk taking. The period covered is the years 2000-2014. Thefigures are annually and the four major banks are; Handelsbanken, Nordea,Skandiviska Enskilda Banken (SEB) and Swedbank.The findings are that financial key ratios that include net income are pro-cycle whereSwedbank has the biggest volatility over the period and that the three other banks areless, but clear pro-cycle. There are also indications that stricter rules have madeimpact on the volatility of the profitability even though the period covered is notenough to ensure this claim. Nordea has had the lowest and most stable capital ratiothroughout the period and the other three banks lowered their debt-to-equity ratiosignificantly after the financial crisis in 2008.

Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
Arbetstidsdireketivets påverkan av den svenska arbetstidslagen : I vilken utsträckning kan parterna på arbetsmarknaden stifta kollektivavtal?
Sweden became a member of the European Union in 1995. When Sweden entered the Union the government also agreed on implementing every law, regulation and directive the Union have and will have in force. One directive the Union wants every country to implement is the Directive (93/104/EG) concerning certain aspects of the organization of working time. This directive includes regulations concerning the relationship between employer and employees. The regulations in the directive must be in force before January 1 2007.One of the main points in the directive is the possibility for the parties on the labour market to reach agreements through collective agreements that deviate from the legislation concerning work hours.
Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster
The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
Arbetsmiljöansvar vid uthyrning av personal
As the staffing agency business is rapidly growing and suffering from accidents resulting in higher sick leave than in other businesses, it is of great interest to analyze which responsibilities prevail between the customer companies and the staffing agencies, when it comes to working environment for hired staff.The purpose of this essay is to clarify the distribution of responsibilities between customer companies and staffing agencies, regarding working environment. I would also like to analyze which consequences this distribution of responsibilities may lead to.To be able to answer these questions, I have chosen to use the legal dogmatic method together with the sociology of law method. I have studied legal sources, literature and also interviewed three persons who are active within the staffing agency business; one person from the Swedish Work Environment Authority, one person from the employers? side and one person from the employees? side.The conclusion of my survey is that the SAM-responsibility is divided equally between staffing agencies and customer companies, since the customer company who hires staff is equated with an employer. The employer must also ensure that there is an organized work adaptation and rehabilitation function within the company.
Samspel mellan miljo?politik, innovation och teknikutveckling : Fallstudier om svenska avlopp, kylska?p och bilar
Within process or manufacturing industries, the production of goods and services or the products themselves may have negative side effects such as pollution. An important task for environmental policy is to control and limit these pollutions, for example via regulatory measures. Although, the efficiency of such measures vary greatly between different industries and an increasingly important task for environmental policy is then to encourage companies to engage in environmentally motivated innovation. Governments can utilize other measures than regulation to indirectly decrease pollution. This thesis aims to analyze such activities and how it affects the innovativeness of wastewater treatment, refrigeration and automobile manufacturing industries.
Samhällets syn på fattigdom : En jämförelse av begreppen "nödtorftig vård" och "skälig levnadsnivå"
The purpose of this bachelor's thesis in social work has been to examine whether society's perception of poverty and poor people has changed over the more than 160 years have passed since the first national Poor regulation was enacted in Sweden. With a social constructionist approach and inspired by the critical discourse analysis we have conducted two studies to find answers to what differences and similarities between the concepts of scanty care (1847) and standards of living (2002). A study based on previous research was conducted to examine how society's perception of poverty has changed and designed in a historical perspective. We also conducted a textual analysis of relevant legal texts and legislative history to show how these texts reflect the society's official view of poverty based interventions targeted to poor people.The two sub-studies show that the concepts at different times in history has been crucial for the community support poor people were entitled to. Our overall conclusion is that despite today's advanced social policy there are many obvious similarities between the concepts of scanty care and standards of living.
Parallel Registration of Ships
In present there is no Swedish legislation regulating bareboat registration of Swedish ships. Despite this absence however shipowners with vessels already registered in the Swedish Vessel Register do not hesitate to take advantage of the positive aspects of bareboat registration and thereby allowing the registration of their ships in another State as well. The fact that there is a lack of legislation in this area has left a legal loophole resulting in Swedish ships being registered in a second State without any regulation providing options or protection for the different parties involved. With this as a background, the main objective of this thesis is to analyze parallel registration of ships, its consequences and the future of dual registration in Sweden. To fulfil this objective another aim is to impart a collected legal and economical presentation of the problems that may occur when a bareboat chartered vessel is registered in two different States simultaneously.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Avbördningskapacitet för Traryd kraftverk: en modellstudie vid dimensionerande flöde
Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.
Hur påverkas insatser för elever i behov av särskilt stöd av beslut på olika nivåer? : En studie av insatser på tre skolor i samma kommun
The intention with this study is to investigate how schools are affected by state and municipal documents when they organize the education for children with special needs. The study is based on following questions.How do decisions on state and municipal level of politics affect the decisions that the principals make concerning organization, and do the school leaders think that the decisions are made on the right level of liability?What is the relationship between economic decisions and pedagogical decisions?What decides whether the schools have children with special needs integrated in their ordinary classes, or if they receive segregated remedial courses, and what are the views on an equivalent education?The study is conducted through interviews with principals of three schools, one politician on municipal level and one special education teacher. The interviews are linked to an historic background as well as current studies and discourses. The study shows that there are contradictions between state, municipality and school goals.
Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
