Certifiering och Gröna skogsbruksplaner idag och i framtiden : en enkätstudie av privata skogsägare på Södra Skogsägarna och deras attityd till skogscertifiering och Gröna skogsbruksplaner
Södra is a co-operative of private forest owner organisation which is owned by 35 000 private
forest owers in southern Sweden. Forest owners in Sweden can choose to certify their
Forestry. Södra uses PEFC (Programme for the Endorsement of Forest Certification Schemes)
as their certification scheme for their members. Those who choose to certify their forest are
obligated to follow the demands for forestry which PEFC requires.
A ?Green? forestry plan is another important tool in the ambition to reach a sustainable

Utomhusgym, några fördelar? : En studie om affekter vid styrketräning inomhus respektive utomhus
PurposeThe aim of the study was to examine the affects perceived by young people aged 18-19 years old after resistance training outdoors versus resistance training indoor. The aim of the study was also to examine if the rate of perceived exertion was affected by whether the resistance training took place outdoors or indoors. What immediate affects are perceived in conjunction with resistance training outdoors and indoors in people aged 18-19 years?What immediate affects are perceived after resistance training outdoors compared to equivalent resistance training indoor in people aged 18-19 years?What perceived exertion level can be seen in conjunction with resistance training outdoors compared to equivalent resistance training indoors in people aged 18-19 years?How does exercise habit correlate with affects and exertion in conjunction with resistance training? Method22 pupils in a secondary school conducted two resistance training sessions, one outdoors and one indoor. A questionnaire about their mood and exercise habits was answered before and immediately after the training session. Rate of perceived exertion rate was also included in the questionnaire the participants received after the workout.
Design av en ejektorspädare samt ett system för partikelmassmätning av dieselavgaser
This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was tobuild a system for particulate mass measurements in one of the engine test cells at KTH. Theparticulate mass measurements are planned to be measured with a TEOM.The exhaust gases must first be diluted with air before the Sample is sent to the TEOM.Therefore an ejector diluter for this matter also was designed and evaluated in the thesis.Emissions measurements have been done both with and without dilution to determine thedilution ratio. Tests have been done for different speeds and loads.Problems with stability of the dilution ratio have been an issue throughout the process andpressure pulsations in the exhaust pipe are believed to be the cause. More tests have to be done tomake sure that this is the problem.One idea is to make the inner diameter of the diluter nozzle smaller and see if it changes thedilution ratio stability.
Kostansvarigas uppfattningar om införandet av ekologiska livsmedel i skolmåltidsverksamheten
The purpose of this study was to examine how food managers of Östergötland County disucss around their possibilities of reaching the government´s orientation towards 25 per cent of the food - procured, prepared and cooked in the school meal - coming from certified organic production. The study was a cross-sectional study in wich a qualitative approach was used. The Sample consisted six food managers in Östergötland. Data processing was done through a semantic content analysis. The result showed that involvment and intrest were significant factors for the introduction of organic food in the school meal. The three municipalities with the highest percentage of organic food used the SMART - concept.
Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :
According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion Sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.
ISP och uppsats. En kvalitativ studie av Kuhlthaus informationssökningsprocess bland uppsatsskrivande högskolestudenter.
The main purpose of this thesis is to examine whether the ISP (the Information Search Process) as defined by Carol Kuhlthau is applicable to Swedish University students. Qualitative interviews were carried out with students enrolled in their thesis course at the end of their university education. The selection is based on convenience Sample of students visiting the university library. The questions are mainly about how to find out the experiences of the students when they look for documents at the beginning of their thesis work. Other relevant questions are about user-education, information literacy and what the students' opinions are concerning a thesis as a part of their education.
Att vara i minoritet : Flickors läsutveckling på mansdominerade yrkesprogram
This essay studied how six girls experienced their reading development during their college education in male-dominated profession programs. The issues assumed were how they experience their literature reading and literature education and what happened with their interest in reading. The theoretical frame included researchers Säljö, Rosenblatt, Gun Malmgren, Olin-Scheller, Ulfgaard and Molloy.The study showed that most of the girls felt their reading had worsened but not because of their male classmates but because of school. They had a lot of homework and participated in so many different school projects which would be completed that there was no time to reading for pleasure. The girls did not like the teachers? literate Sample and did not like the methods used in learning literature.
Den reviderade Kodens effekt på informationsgivningen i svenska bolags årsredovisningar
As of 1 July 2008 the revised Swedish Code of Corporate Governance applies to all Swedish companies whose shares are traded on a regulated market in Sweden. The purpose of this thesis is to investigate whether the introduction of the revised Code has affected the disclosure practice among Swedish companies. We investigate a Sample of 43 small and mid cap companies listed on the OMXS Exchange that has previously not been covered by the regulation. We develop a disclosure index, measuring the disclosure level in annual reports before and after the introduction of the Code. The results from the study show that disclosure level has not increased after the introduction of the Code.
Mail Exchange Protocol (MEP): Ett utkast till nytt protokoll för elektronisk post
SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.

Utbildningens betydelse för hälsan : En studie i skillnad på ohälsa mellan akademiker och icke-akademiker
The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed Sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.
Adaptiv temperaturreglering av bostadshus
The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every Sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.
