This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

Length of stay IN PRESCHOOLA qualitative study based on nine pre-school teachers.

ABSTRACT The purpose of this medical record research was to study 30 patients with chronic subdural hematoma on a neurosurgical clinic, mapping documented nutritional status, preoperative fasting and hydration and energy supply before surgery. In addition peroperative administration of fluid and vasoactive drugs, as well as postoperative complications and length of hospital stay were studied. The mean age of the patients was 71 years. Nutritional status was evaluated in 12 patients, out of these seven were judged to be at risk for under nutrition. Fifteen patients had surgery day 1 (total fasting time on average m 11 h), eleven had surgery day 2(29 h), three had surgery day 3 (35 h).

Aims: The aim of this study was to describe how patients that received a patient diary after their stay at an intensive care unit (ICU) had used the diary and if they found it useful for dealing with their stay in the ICU. The study also aimed to investigate if the patients felt a need for discussing their stay in the ICU and the diary with a registered nurse.Method: The study was performed as an interview study with explorative design. Six informants participated in the study. Recorded personal interviews were held with the informants. The recorded material was transcribed and analysed using qualitative content analysis on a manifest level.Results: This study shows that informants have used their diaries to establish a conception of what they have experienced during their stay in the ICU.

AbstractJohannes Åberg 2012: Har längden betydelse? ? En kvantitativ studie av elevers textstrukturer.Does the length matter? ? A quantitative study of student text structures. Essay writing is one part of the national test in the school subject Swedish. Here the student gets the opportunity to demonstrate that it is able to follow instructions and produce a coherent text. The examinator's task hereby becomes a troublesome process with subtle distinctions between rights and wrongs.

The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.

The study was conducted on 72nd company at Livgardet in order to find out what motivators makes the soldiers stay. The material in the essay is based on an interview with soldiers from the 72nd company. The motivators are then categorized in the model Employee Motivation: A Powerful New Model. The model is based on human drives and I used as a tool for the analysis to identify lack of motivation in a working place. The study shows that the key motivators that make soldiers stay is: the opportunity to go on a peacekeeping mission and comrade/esprit de corps, the soldiers state that they will quit without these two essential motivators.

A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.

Self- determination and autonomy of elderly people living in long- stay care homes is the forefront of discussion in the media and in society today. It examines the extent to which elderly people actually have the opportunity for self- determination and to what extent they have an impact and influence in their daily lives. A suitable way to look at how the quality of long ?stay care looks like is too look at the extent to which the user has self- determination. The aim of our study was to examine how self-determination appears in long- stay care homes. We also talk about in what way the officials perceive self- determination and how elderly identify and perceive their right to self- determination and the importance it has for the individual. The essay has been made with the help of interviews and surveys on a number of long-stay care homes in Skåne.

In this work, I describe the factors that affect the bucking of pine logs on the basis of the machine operator. The aim is to find an explanation why the bucking differs so greatly between requested length results and the actual length results in pine bucking. The used methods in this study were data from simulated pine outcomes, data from earlier length outcomes and analysis of the harvesters' PRI files. This is to identify the problem. To explain the background to the problems a qualitative research interview was used.

The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.

This essay aims to examine and compare the attitudes of decision makers in the local government and representatives of pensioners in two different geographic areas. The main questions were:- their attitudes towards the "stay home principle" (kvarboendeprincipen, a principle that aims to make it possible for people with a handicap, disease or age to stay in their homes instead of moving to nursing homes).- their attitudes towards nursing homes for old people- their attitudes towards the possibility of staying at home when you are old and handicapped and in need of care.The essay is built on qualitative research methods, based on interviews and on a review of research in the field.The author found a complex picture of attitudes. Everybody thinks that the best is to live in your own home as long as possible, except from those who live with Alzheimer´s disease. They showed different opinions on the issue of the need for moving to nursing homes. This might result in forcing people to stay at home.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.
