MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?
The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.
Effektiva Institutioner eller Symboliska Samarbeten? En jämförande analys av effektiviteten hos Helcom och Medelhavsregimen
The aim of this thesis is to examine the institutional effectiveness of the environmental institutions Helcom and the Mediterranean regime, by using Haas, Levy and Keohane's "the three Cs"; governmental concern, contractual environment, political and administrative capacity. The method used is a comparative analysis.This study takes into consideration the specific structural and economic factors that are prevailing in each region where the environmental regime operates. This study also takes into account the influence of the European Union as a factor that affects the environmental progress.By focusing the study on the line of conduct concerning hazardous substances by respectively regime this study shows that the institutional effectiveness is fulfilled in neither Helcom nor the Mediterranean Regime, although Helcom has been more successful. The lack of state capacity is the most restraining factor for both developing countries and countries in the transition towards being developed, to achieve a good environmental status of the sea. This study also shows that the European Union sometimes has a greater impact on the environmental progress in states, rather than the environmental regime in countries that were/are aspiring members, thus showing the ineffectiveness of the regime..
Koncentrisk hämning och stimulans av bakterietillväxt i agarkulturer
The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..
Raä 977 - En lokal och tre aktivitetsytor. : En tvärvetenskaplig undersökning av Raä 977 vid Vojmsjön i Vilhelmina socken
This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.
Lagerhantering på Voice AB
This examination paper is a lead in the educational program Industrial Management at Jönköping University. The paper itself contains an analysis of the warehouse organisation and its efficiency at the furniture company Voice AB in Torsvik, just south of Jönköping, Sweden. The report also contains propositions to raise the level of efficiency in the company warehouse and warehouse management.In the investigation of the warehouse a number of possible improvements were found. Examples are lack of a system for labelling shelves and racks, lack of an efficient location system and development possibilities in work routines. For the empirical investigation both qualitative and quantitative methods ware used.
Betalningsmodeller för det svenska elnätet : Vilken modell kommer att fungera bäst för konsumenten?
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Värdering av föroreningsrisk - Ett förslag till angreppssätt för värdering av föroreningsrisk till följd av emission från en vägkonstruktion
When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.
Ett medlevarskap det är något alltså, något alltså jättespeciellt : - En studie om hur ett behandlingshem kan påverka anknytningsmönster
Author: Maria Gustafsson and Sofie IngströmTitle: ?Ett medlevarskap det är något alltså, något alltså jättespeciellt? - En studie om hur ett behandlingshem kan påverka anknytningsmönster.Keywords: relationships, attachment, home of treatment for youth, youth, significant others, trust.In our essay we had an aim to see how Hassela, Gotland affected the youths who lived there. We wanted to know if they had a secure or insecure attachment to their parents and if the attachment was affected after a time at Hassela. We were interested in what kind of attachment figures they had before they came to Hassela, Gotland and how they looked at themselves and others before they came there and if that had been changed.We used a qualitative method and we did ten interviews with youths who had been at Hassela, Gotland eight months or longer. We based our analysis on the attachment theory.
En vampyr i sitt liv : En studie om elevers syn på gymnasieskolans arbete mot diskriminering, trakasserier och kränkning
The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.
Instrumentbordets sterilitet
Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.
International Strategy Implementation: Understanding of Local Challenges in China
The thesis has two purposes. First, to give a practical insight into the challenges that Swedish companies might face, and how these challenges are tackled, when implementing strategy in a local area. Second, to develop a general applicable model as a conceptual contribution to the field of international strategy implementation in local areas. This empirical-driven thesis is written in a qualitative and explorative approach, where abduction is adopted in order to find mysteries and contribute to the forming of new theories. The empirical foundation is twenty-two interviews and observations of three large Swedish companies.
Jämförelse av plackutbredningen under fyra veckor hos individer som kompletterar sin mekaniska tandrengöring med munsköljning innehållande antingen essenslösning eller CPC samt upplevelser av smak och känsla i munnen - en pilotstudieComparison of plaquef
The aim of this pilotstudy was to compare the plaqueformation during four weeks in individuals using a mouthrinse containing either essential oils (Listerine Cool Mint) or CPC (Colgate Total) as a complement to their ordinary toothbrushing. Another purpose was to evaluate the individual?s experiences regarding taste and sensation in the mouth after rinsing. A semiblind, clinical pilotstudy was conducted in 20 individuals at a university in southern Sweden. According to a screening-plaqueindex the individuals were stratified into two intervention-groups of ten people, one group rinsing with essential oils and one group with CPC twice daily as a complement to their toothbrushing routine.
Vad är viktigast i staden? : Utveckling av ett lokaliseringsverktyg för stadsplanering
This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.
Kiviksgraven : analys av dess historia och framtid sett utifrån bevaringsfrågor
This essay focuses upon the Kivik monument and its conservation difficulties, since its discovery at 1748 until modern time. The Kivik monument is found in southeast of Scania, and dated within the Bronze Age period. The perspective of the conservation on the monument has merely been on the monuments inner cist of stone and the rock carvings on the cist-slabs. When the monument was first archaeological examined at 1931, its sizeable cairn (75 m in diameter) had almost vanished and the cist was sheltered by a casing of concrete and metal roof. Between 1932 and 1933 the monument has undergone a large-scale restoration, and this criticized restoration resulted in a low antiquarian value with the responsible authority.
Rosenlunds bankar : Erosion och förändring sedan 1960
During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.
