Effektivare röjningssätt med kedjeröjsågen?
After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce.
The purpose of this thesis is to study the new brush saw with chain and compare it with the Conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the Conventional clearing saw.
Dokumentärfilmproduktion ur ett ljudtekniskt experimentellt perspektiv
This paper is a study of documentary film production with focus on the filmmakers choice and usage of sound equipment. Using professional articles and literature have first of all helped us determine a standard for the Conventional use of sound equipment in documentary film. Afterwards, by analyzing our own interviews we?ve received answers on how filmmakers relate to the Conventional usage and why they select equipment as they do. Thereafter, we describe a technical method which helps a filmmaker to be able to record sound for documentary film on his/her own, using simple measures without reducing quality.
Mekaniskt snytbaggeskydd
Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested.
Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the Conventional methods used today. The study was conducted over a three week period.
Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe.
The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of Conventional methods.
Diversifieringsmöjligheter och deras effekt på avkastning : en jämförande studie av etiska och traditionella fonder
Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and Conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.

Jämförelse mellan två olika plastningsprinciper, Cross Pac kontra konventionell plastning :
Baled silage has become one of the most important conservation methods in Sweden. Because
we take our grass as silage we get the quality and the good hygenic that we would like to
have. Silage has become a big buisiness also in the horse feeding where many of the breeders
have changed from the hay to the hay-silage. The difference between regular silage and haysilage
is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands
on machinery and wrapping material since the grass gets sharper and harder to press together
real hard.
The main reason for the test was to compare two different systems for wrapping, the new
Cross Pac and Conventional.
Konsumenters synsätt på ekologiska livsmedel avseende frukt, grönsaker & rotfrukter : - En tvärsnittsundersökning ur ett konsumentperspektiv
Background: Pesticides in Conventional food may be related to morbidity and mortality. Furthermore pesticides have a negative impact on the whole ecosystem. Organic food can presume better health as they contain less chemicals and toxins and contribute to sustainable development efforts.Objective: The aim was to examine what attitudes consumers have regarding to purchase organic fruit, vegetables and root vegetables.Methods: The association between consumers? views on Conventional food and organic food was investigated using questionnaire given to a population sample of men and women aged by 23-65 (N=60) in grocery stores and in a fitness center. The study was based on a cross-sectional study in a municipality in central Sweden.Results: Consumers were interested to buy organic food.
En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik
The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a Conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the Conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the Conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.
Samarbete mellan lantbruksföretag : möjligheter och problem
Nowadays, cooperation is necessary and this study tries to illuminate the possibilities and problems about cooperation in fiction between 7 small/midsize farms in Skåne. Conventional Farming is done with grain and sugarbeets as specialization. Calculation of machine costs have been done and compared in the study, both for the farms in thorough and the fictitious operation companies. Business ratios as depreciation/ha, interest/ha and maintenance/ha have been calculated.
In this essay we present a proposal about how a practical implementation can be done. In the proposal there is an example how the distribution of work can be done.

Miljöbilar - ett steg närmare en bättre miljö
This report concentrates on why more people do not choose an environmentally friendly car instead of a Conventional car. To find this answer we have used theories that include decision - behavior and environment - philosophy. We have also made four surveys, which includes several interviews. The results of these interviews, together with the secondary data we have found, have been analyzed against the theories made by our choice. We have found that the stimulus that we have today isn?t enough to make more people choose an environmentally friendly car instead of a Conventional car.
Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm
One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands.
The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a Conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.
Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data
To understand the motives, and perhaps more importantly the barriers, for farmers to convert from Conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in Conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
Stålfiberarmerad betong för platta på mark : -En kostnads- och sprickbreddsanalys
AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the Conventional reinforcement. Replacing Conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only Conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.
Det ekologiska valet : En konsuments väg till val av ekologiska livsmedel
This thesis examines the underlying components that affect consumer behavior regarding organic food. The thesis theoretical framework is based on Ajzen and Fishbein?s The Theory of Reasoned Action combined with theories regarding involvement and routine purchases. The empirical material is based on a desk research with 19 research papers between the years 1994 till 2009 and sales statistics over organic food. The thesis conclusion shows that the underlying components when looking at attitude towards Conventional food are price, taste, expiration-date and healthfulness. While the components for involvement in organic food is the environment, personal health and supply.
