Bacteria are exposed to evolutionary pressure to an extent unlike other organisms. This leads to a high degree of adaptation to its surrounding. This thesis investigates the degree of adaptation towards higher accuracy in the transcription of DNA to RNA in coding sequences in the DNA of the E. coli bacteria. Two coding sequences with different nucleotide contents were investigated.

Safety, its a word not commonly associated with elderly people living alone. There is however a device that is supposed to bring safety, and enable elderly people to continue living in their present household - an emergency dialer. However these devices does not serve their own purpose in terms of design. Thepurpose of this study is to create an emergency dailer that everybody would want to put on their wrist or bedside table. The market for these devices have looked the same for the last twentyfive years, despite of society´s advancements in both design and technology.

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

Illegal logging and its related trade is of great concern around the world. The European Union Timber Regulation (EUTR) is a regulatory approach by the EU to prevent illegal timber and timber products to be placed on the European Union inner market. This means the regulation affects both actors in the member countries as well as the actors exporting timber and timber products to the EU from non EU member countries. This study aims to study the implementation process of the EUTR in Bosnia and Herzegovina (B-H), and its preconditions. Institutional theory is used to understand and explain how the EUTR affects B-H organisations? business environment, and how the organisations choose to respond to the EUTR.

This masters thesis is a study of the ideas brought forward in the literary magazine 40-tal. The methodology involves the adaptation of a literary sociological perspective where the ideas of the young literary avantgarde in the magazine 40-tal interplays with the established philosophy of the Swedish society during the period 1944-47. The main purpose has been to examine 40-tal as a product of supreme individuality that originates a unique climate of ideas which exceeds the involved collaborators individual writings. I have thereby related my analysis to the Marxist oriented theories of Raymond Williams. This has been done in order to see how the external pressure of the social structure and the market acts together with the internal pressure of keeping up with the times and how this affects the individual authors and the process of creating.

Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

Syftet med denna litteraturstudie var att beskriva vilka omvårdnadsåtgärder som kan förebygga uppkomsten av trycksår samt vilken förmåga att identifiera patienter som riskerar att utveckla trycksår sjuksköterskan har med de bedömningsinstrument som finns. De vetenskapliga artiklarna (n = 20) som ingick i studien söktes via Högskolan Dalarnas databaser Blackwell Synergy, PubMed och ELIN@Dalarna. Sökorden som användes i olika kombinationer var pressure sore, pressure ulcers, nursing, routines, treatment, knowledge, methods, management, measures, risk assessment, scales, risk patients och prevention/preventing. Inklusionskriterierna var att de skulle vara empiriska, skrivna på svenska eller engelska samt vara publicerade efter 1997. Resultatet visade att det finns många olika förebyggande åtgärder som vidtas.

Death can be seen as a sensitive subject and can by that be difficult for many people to talk about. Working as a nurse can imply caring for severe ill and dying patients, which can be regarded as a task that makes great demands. The aim of the present literature review is to illustrate nurses' experiences of problems in association with the care of dying patients to be aware of these. Nine scientific articles were analysed and the result showed that the problems the nurses experienced could be related to four different categories: problems related to organisa-tion/resources, to the nurse herself, to the patient and to family members. The literature review also illustrates consequences of these problems for nurses, and which components that could simplify the nursing care of dying patients..

The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

The purpose of this thesis is to investigate how students who study with Problem-based learning PBL in a distance learning course perceive the support from the university library. I first went into adult education, PBL and distance studies, one at a time, and then took a look at the combination of problem-based learning in distance studies. During the investigation, I conducted five interviews using a phenomenographic method to understand how the students perceived the support they received from the university library. The university library gives a lot of support but what I noticed while I was writing was that it is difficult to reach the students with the information regarding the help that is available to them. I give some example on how to develop the support and find that the students have a wide range of different needs for support from the library depending on their individual situation, social context, academic ability, location and course of study.

There is a growing awareness that multinational companies have opportunities to influence political conditions. Ethical activities made by multinational companies and ?Corporate Social Responsibility? (CSR) can therefore function as a positive input in society. The primary purpose of this master thesis is to investigate CSR´s contribution to strengthen human rights, and thereby to democratization. The research questions are listed below:1.

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today?s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods? data-base.Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes.

In this essay I analyse the constructions of gender in the series The Phantom by Lee Falk. I apply David Tjeders readings of the bourgouise masculinity, its sensitive character and great risk of falling into unmanliness, when discussing The Phantom?s masculine development. I have analysed three adventures of The Phantom from the years 1937, 1977 and 1996, all authored by original creator Lee Falk. I argue that The Phantom increases his use of violence, therefore risking a loss of character.
