In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Quality assurance means to systematically work for better understanding of the customers needs, demands and expectations. The goal for this study was to investigate how quality can be assured in the job follow up that is made by forestry contractors after soil scarification and planting. The study consisted of a description over the current follow up process at SCA forest AB Jämtlands forest administration, analysis of current follow up situation and an investigation of follow up process made by contractors in other line of business. The first step was a statistical comparison where the own follow up made by contractors were compared with follow up made by SCA them selves over 100 stands. Two soil scarification contractors and two planting contractors carried out the silvicultural measures. The results showed that significant differences between a number of quality factors measured, for example number of approved plants or approved scarification points, average score on stand and number of totally planted plants.

The aim of this study is to investigate methods of collection development, the users? influence on selection and quality aspects, focusing on non-fiction literature in Swedish public libraries. To find out opinions of collection development, I use the method comparative literature study. Antonio Gramsci?s concept hegemony forms the theoretical background, and hegemony as concept is related to a library context by using Maj Klasson?s text on the librarians? different positions of authorities.

My essay begins with two stories showing two different perspectives when looking at learning in preschool. These two different learning styles I have chosen to call, the measurable and the difficult to measure learning. As a pedagogue I am involved in both events. In these events I describe how different we pedagogues interpret our governing documents on children's learning. By describing how the educational activities are designed differently in the two events, I try to highlight the pedagogues views on learning in preschool.

The main purpose of this thesis is to examine the process of selecting films at Bibliotekstjänst and at Swedish public libraries. The tools that have been used for analysing and interpreting the results from the interviews and the questionnaire are theory-based models describing the selection process concerning film and Carl Gustav Johannsen?s quality definitions. The result of the investigation shows that Bibliotekstjänst doesn?t really work with any quality definitions in their selection process.

This essay discusses the interaction between the authorities in Nacka municipality in Sweden and supervisors within the eldercare. In Nacka politicians have gradually started delegate responsibility for how care-giving for the elder should be done and focus instead on formulating economical objectives and overall rules. It is up to the approved supervisors of eldercare to deliver good care and quality. The method chosen to accomplish this is public choice. This method is a part of the big New Public Management (NPM) reform which have had a big impact on Swedish public sector since the 1980´s.

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

A lot of research has been done about how omitting breakfast affects adolescents and their short time cognition. Cognition is complex as a concept and is measured in different ways and the existing research in the area often compares different types of breakfasts instead of the difference between eating and omitting breakfast.Objective: To evaluate the scientific evidence for an association between adolescents? breakfast eating and short time effects on cognition in adolescents.Search strategy: To find relevant articles a systematic literature search was made in the databases PubMed, Scopus and Cochrane. Search terms that were used were: children, young adults, adolescents, cognition, and breakfastSelection criteria: Ages 12-20 years, measures cognition, RCT, studies comparing breakfast eating with omitting breakfast, human studies, language English or Swedish, no sick adolescents or adolescents with diagnosis.Data collection and analysis: Two original articles met the inclusion criteria and were reviewed by the SBU audit template for RCT studies.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

Since January 1st 2008, companies have the opportunity to become certified by the new common customs system Authorized Economic Operator (AEO). This opportunity is presented so that authorities together with operators are trusted to ensure that it is the correct cargo that gets transported. Attends Healthcare AB (Attends) has decided to implement this certification. To qualify there are a number of criteria that needs to be met. The aim of this thesis is to verify if Attends can meet the required criteria.

As the past century?s technological development has progressed the Swedish boreal forests have transformed into dense, highly productive, homogenous and coniferous forests. The area around Saxdalen in Ludvika municipality has long been dominated forests which have been heavily worked since the 18th century. There are in Ludvika 119 000 hectares of productive forest land. Around 70 percent are owned by forest companies and 20 by private forest owners.

En röststörning kan sägas föreligga då rösten inte fungerar eller låter som den brukar så att det påverkar kommunikationen. Prevalensen för röststörningar uppskattas till omkring 6 % av den vuxna befolkningen. När rösten inte fungerar som den ska leder det till emotionella, sociala och funktionella svårigheter för individen och har negativ inverkan på livskvaliteten. Voice- Related Quality of Life (V-RQOL) är ett självskattningsformulär som mäter vilken inverkan en röststörning kan ha på individens livskvalitet. Detta instrument är internationellt välanvänt, men har inte funnits översatt till svenska.

This is a potential reason for possible cholesterol-lowering effects.

This empirical work and base has been to analyze the new high school reform that the Swedish government introduced as a statement 2008/09:199 about: Higher demand and quality within the high school. This statement became legal through the government vote in spring 2010. But above all it is the investigation (SOU 2008:27) that is the central piece for these new examination changes for high school students that will come into effect 1 of July 2011. The purpose and questions asked in this analyze has been if the reform takes its base in a modernistic (traditional) way or a late modern scientific perspective. And also to find out how these new quality amendments in the investigation makes visible about the high school and what the purpose are about the changes. When scientific theories in these analyze is placed against the reform, the result shows that the modernization process reflects more of a late modern aspect, which constantly reappraise in a changeable society.
