Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

There are several ways to identify individuals with dry mouth, but there are few studies made in which the different methods have been compared with each other.The aim of this pilotstudy was to compare different methods for identifying individuals with dry mouth. Fifty individuals aged 50 to 75 years were included in this studie. These where randomly chosen among patients at the dental clinic at Kristianstad University College. Four different salivary measurements were conducted: 1) collection of unstimulated saliva, 2) collection of stimulated saliva, 3) the so called ?mirrortest?, and 4) analyse using cottonrolls.

The purpose of this study is to contribute to our knowledge about what methods? teachers say they use in the work with pupils? early reading acquisition, and how they evaluate the pupils´ reading development. I also like to find out what educational interventions teachers believe that pupils with reading difficulties need, and how they say they work to meet the needs of these pupils. The project is based on the following questions: What methods do teachers say they use in the work with pupils early reading acquisition? What extra resources do teachers consider that pupils with reading difficulties need? How do teachers evaluate children's reading development? In order to answer my questions, I've done qualitative interviews with three teachers, at two schools, in two medium-sized municipalities.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

The purpose of this essay has been to investigate if the national test results, in the subject of Swedish B at upper secondary school, are affecting a student?s final grade in varied degree among different teachers. The purpose has also been to investigate if the assessment of these tests is equivalent among different teachers. This particular investigation showed that there are big differences between how teachers grade, in relation to achieved results on the national test. According to the Swedish National Agency for Education, the teacher should take all performance information available into consideration for each particular student.

Students at the School of Engineering at Jönköping University have on behalf of the swimming organization ?Nässjö Sim och Livräddningssällskap? conducted research on how to monitor and evaluate swimmers and swimming groups in a simple and efficient manner with a focus on usability and user friendliness. Since no system existed that could meet these requirements, the client had a desire to tailor and develop such a system. The purpose of this work was to develop a system that would work as a tool to be used by coaches and swimmers alike and allow them to eventually follow the development of swimmers and swimming groups. The organization also wanted to have the ability to create tests and exams, both for land and water training, register these in the system and in a structured way know which swimmers took and passed these.For this thesis, the following questions functioned as a framework for progress.UsabilityHow to design a usable system and what is required?SystemWhat type of system is best suited to meet the client's requirements and preferences?Competition resultsHow can one retrieve all the competition results for swimmers of Nässjö SLS?DatabaseWhat type of database is best suited to easily share data with an external existing database?Usability has been the main focus throughout the project.

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

Research shows that people with burnout experience a high degree of impairments in a range of cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported cognitive problems? Third, are the self-reported cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.

To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.

In this study I have analysed the national tests in Swedish between the years 2006-2010. These tests are given to all students in the public schools in grade 9 and 10. I wanted to see if I identified an over-representation of a certain category of people in the texts given to the students. I analysed the texts from an intersectional perspective and I used primary Lena Martinsson (2007), Framtidens feminister and her categories and theories and Moria von Wright (1998) Genus & text- när kan man tala om jämställdhet i fysikläromedel?, and her gender categories in my study.

The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
