The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand.
The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted.
The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages.
The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent).
Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated.
Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same.
However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time.
If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Höftfraktur och hjälpmedel : En kartläggning av hjälpmedelsinnehav hos patienter med höftfraktur
This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.
Dekoration av plasttallrikar
A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.
Evidensbaserad logopedisk intervention vid strokeorsakad afasi hos vuxna : En verksamhetsknuten litteraturstudie
Background: The speech- and language deficit aphasia affects 12 000 persons annually in Sweden. Aphasia is caused by injury in the brain and the most common etiology is stroke. According to the tool for describing and assessing aphasia, A-FROM (Kagan et al., 2008), the four following aspects of aphasia need to be considered: severity of aphasia, participation in life situations, communication and language environment and personal factors. Several different interventions and treatments can be performed in every domain. There is scientific evidence for interventions performed by speech and language pathologists; however, the question is yet being discussed since results are unambiguous.Purpose: The main purpose of this study is to investigate which aphasia interventions performed by speech and language pathologists that are supported by evidence.
Empowerment: vetenskapligt paradigm eller politisk kameleont?
The purpose of this study was to examine whether the success of theconcept of empowerment in the field of social science can be explained by referring to it as the new paradigm replacing the former paternalistic era. Therefore, I investigate if the character of its history, domicile and practice has the same distinguishing features as the scientific progress. The analysis is based on Thomas Kuhn's definition of a scientific paradigm through the concepts of consensus, crisis and revolution. I also look for alternative ways to explain the sudden appearance of empowerment at the world agenda. Due to the lack of a uniform definition of the concept and the absence of common approaches in the stimulation of empowerment it's difficult to argue that the situation is marked by consensus.
Spam : den nya tidens onlinegissel
This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.
Byte av systemutvecklingsmetod : En verksamhetsnytta eller en nödvändighet?
AbstractSystem methodology is in the very heart of system development, it is a crucial part of how you define your work, how you choose to approach the actual problem at hand and how to solve it. Researchers in the system development field has shown that not all methods in theory are in compliance with how it is practiced by the companies who use them. In our thesis we have studied a larger international IT- company and one of their local offices in Sweden, who some years back changed their system development method from a more traditional to an agile one. Our aim of this study has been to establish whether both of these methods has differed between theory and in actual use, and if so, why this has occurred and what the underlying rationality might have been to promote this change. Our questions that we sought to answer were; 1.
MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING
The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.
Ibland känns det nästan som ett övergrepp - en studie om språkets betydelse i omsorgen för invandrare med demens som bor på särskilt boende
Purpose/aim: My purpose is to illustrate the significance of the language in communication with immigrants having a different native language, who suffers from dementia. The three main questions have been:How important is the native language in the communication with immigrant who suffers from dementia?What consequences can happen for the immigrant who does not understand Swedish? How can we use the salutogenesis point of view to create satisfactory care for immigrants who has difficulties to make them self understood in the Swedish language? Material/method: I made qualitative interviews with staff working in nursing homes with dementia care. I also searched scientific articles and other findings in this area of science. Main results: The best care for immigrants with dementia is nursing homes where the staff speaks the immigrant?s native language.
Utomhuspedagogik : Lärares tankar och erfarenheter av utomhuspedagogik
Abstract This research is about outdoor education as a pedagogical method, and its purpose is to find out six teachers thoughts about outdoor learning, and their experiences about this method.Many philosophers and advocates for the outdoor education claims that learning is best acquired when children uses all their senses and that school subjects that are thought in the classrooms also can be thought outdoors. Studies have shown that children´s health and learning ability increase when they are thought outdoors.Interviews and observations have been done.My questions are: How do the teachers practice outdoor education in their classes and what is the result? Which subjects do they use in outdoor education? Do the teachers see any obstacles using the outdoor method and why do the not use it to a greater extent? Keywords: Outdoor education, outdoor mathematics, learning and effects, children, thoughts and expiriences. .
Den ultimata träningsmetoden?
Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).

Norrberga Skolmodell- En ny modell av skola : Vad några elever i sjätte klass tycker om sin skola
This study titled School Model of Norrberga- a New Model of School. Some opinions that six pupils in the sixth grade have of their school is an explorative study. The purpose of this study is to some extent explain the ideas behind this quite spectacular model of school and the intentions of the City Council of Norrberga as they decided that all the schools that were to be renovated or built in the town of Norrberga had to follow a specific script. As I first visited The Moonlight School I was puzzled. How do the teachers work it out? But, above all: Do the pupils work it out? What do they think about their school? When I was to write my final essay I wanted to try to sort this school out in more scientific terms. There is a nice, warm atmosphere at the school and the pupils make good results.
