Ständiga förbättringar inom verksamhetsprocesser : en studie mellan läkemedel- och kärnkraftindustri
The purpose of thesis was to investigate and compare how two companies within pharmaceutical industry and nuclear power industry are currently working with quality development regarding continuous improvement and Lessons Learned in business processes. In addition, a simple comparison was made with the automotiveindustry.McNeil AB are improving their processes continuously and are according to the findings of this report performing well in their pursuit of world-class pharmaceutical production. They have a well functioning process regarding improvements proposed in weekly improvement meetings engaging all employees. However, during interviews it was made clear that the functionality of the process which administer improvement proposals generated in addition to, or beside the weekly improvement meetings, were inadequate. McNeil AB is proposed to administer this through an IT solution instead of by paper and e-mail, that simplifies the process of adding, implementing and follow up an improvement proposal.The nuclear power plant Ringhals AB recently made major improvements in their business processes as well as the plant itself.
Skogsbränsleuttag vid förstagallring och dess påverkan på beståndsutveckling : simulering i Heureka med olika skötselprogram
Stands where pre commercial thinning has been ignored or inadequate often tend to have high stem density and low average diameter when they reach heights of thinning. In such stands, it can often be expensive to do a conventional pulpwood harvest as a first thinning. This study investigates the development of the stands and the economic outcome of forest fuel extraction, or a combined harvest as alternatives to the ordinary pulpwood harvest. Simulations in Heureka StandWise were performed for two thin and dense stands, which were constructed by data from the Swedish National Forest Inventory. The simulations show that the extraction of forest fuel in first thinning at an early stage can provide higher net revenue compared to conventional pulpwood harvest at the same time or later.

Tyskland och skuldfrågan : En historiografisk och komparativ studie av svensk och tysk Förintelsefacklitteratur, 1996-2010
The present study is primarily of historiographical type, but also uses comparative method and qualitative text analysis. It mainly aims to explore how Germany and the issue of guilt have been portrayed in Swedish and German nonfiction literature (excluding teaching materials) during the years 1996-2010, in the context of the Holocaust, but also makes a comparison between these two countries' depictions. Furthermore, it also examines whether it is possible to link the various depictions to specific theories, in this case determinism together with the actor and structural perspectives, as well as to other potential factors such as the authors' personal connections to the Holocaust or the millennium. In addition, overall trends is an aspect which is examined. Despite the fact that the Holocaust has been the subject of extensive research, no study with the same selection as this one has been carried out before.

Skogsentreprenör 2007 : en kvantitativ studie av organiserade skogsentreprenörer i Sverige
SMF Skogsentreprenörerna is a nationwide organisation for Swedish forestry contractors. It has about 750 organised companies with somewhere around 1500 logging machines. These machines perform well over 50% of all yearly landed wood in Sweden. The members of SMF also performs more and more of other functions in Swedish professional forestry, such as soil scarification, planting and pre-commercial thinning of younger stands.
In order to determine what major priorities SMF should focus on in the future a member survey was initialised and carried out by SMF together with Daniel Larsson-Snygg, student at the swedish university of agricultural sciences SLU.
This report presents the result of this survey sent out to all members of SMF. It is intended to answer a number of questions about their entrepreneurship such as:
What different kinds of work do these companies perform? How many machines and employees do they have? How old are the company owners and their employees? What are their thoughts about the future of their business? How well does SMF serve their members needs?.
Fenylbutazon - tillåta vid tävling?
Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.

Naturlig haptisk kraftåterkoppling från volymdata
As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.
Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge
Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.
Korsförlamning hos häst : fodrets påverkan
The purpose of this thesis has been to gather knowledge about the complaints of tying-up in
horses and to show that the importance of feeding. The thesis includes a literature review of
tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry,
horses occasionally suffers from tying-up, a muscle disease. An increased knowledge
about the disease is demanded by riders and trainers as the disease disrupts training and
competition of suffered horses. A cross-country horse works very hard in training and during
competitions but the work bouts are long enough for the muscle cells to use aerobic pathways
in the metabolism.
