Hur håller sig skogsentreprenörer uppdaterade gällande författningar och föreskrifter?

Over 90% of forestry work is carried out today by contractors, thereforeclear agreements between the client and the contractor it is of utmostimportance. Contract Packages for work within the forest sector (APSE) is acollection contract templates that the industry jointly developed for thispurpose. The purpose of this thesis is to examine how forest contractors doto keep themselves updated of the current laws and government regulations,which channels are available to accomplish this and what possible obstaclesmay occur. 20 interviews were conducted with contractors engaged inlogging. The results show, among other things, the availability of and whichchannels most contractors use out of which aggravating circumstances existand how strong they are perceived and what is expected of the client in thisregard..

Folkbibliotekarierna och läsfrämjandet ? en diskursiv studie av svensk bibliotekspress 2012-2013

The aim of this thesis is to examine how the identity of the public librarianwith regard to reading is manifested in the library field. The approaches thatare taken to reading and readers are examined as well as the consequencesdifferent approaches might have. The empirical material is based on 93articles published in Swedish library journals. The theoretical andmethodological starting point is discourse analysis. The application ofdiscourse analysis according to Michel Foucault?s hypotheses reveals threediscursive formations regarding the professional identity of public librarianswithin the framework of reading promotion: The public librarian asguarantor of democracy is related to the public library's original mission offostering, cultivating and educating citizens.

Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study

Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market. Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.

Utvärdering av en Magnetic Harmonic Traction Drive

In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

It touches on subjects such as A/D-conversion. PWM-control and PID-control. The sensors used in the platform are a gyro and an accelerometer.

Ändamålsanpassad TINA-sortering av sågtimmer :

Swedish sawmills of today suffer from unsatisfying economy with high costs and low benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner. Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are mainly manual but can in some rare cases be automatic.

Strategisk utveckling: En studie av strategi hos internetbaserade företag

Strategic development is something that concerns all companies, regardless of which industry they?re in. There is extensive research on this topic but one can question if the same theory also applies to E-businesses. Using case studies, this paper looks at strategic development in E-businesses and tries to answer whether strategic development in internet based companies is unique or if existing theory can still be applied. The predominant approach is to look into if E-businesses, due to a turbulent environment, rely less on market research and focus more on internal resources than would be expected by companies in more stable environments.

Fysikämnet i förändring : Är fysiklärarna rustade för de nya momenten; den kondenserade materiens elektronstruktur, nanoteknologi samt materialfysik?

The aim with this essay is to find out what the expected changes in the subject physics will lead to for teachers and their pupils in ?gymnasiet?. The new fields we have chosen to focus on are electronic structure of condensed matter, nanotechnology and material physics. By studying earlier used curricula and textbooks, we illustrate what teachers may have come into contact with in their teaching careers. The main focus lies on what teachers claim to know about the fields mentioned above and if there is a need for further education.

Lågtempererad fjärrvärme i Umeå

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

The Best Thesis of the Year!: A study on the effect of customer generated ratings in advertising

In this thesis, the impact of collective ratings on customers? perception of a product is examined. The empirical data comes from an experimentally designed survey where the effect of collective ratings is measured in the setting of a traditional advertisement for a feature film. In contrast to what previous research would suggest be to the expected outcome, the authors of this paper concludes that in comparison with alternative designs of advertisements, there are no measurable advantages of including collective ratings in advertisements from the marketers point of view. We find two explanations to the result: (1) people tend to self-report that they are more influenced by collective ratings than they actually are, and (2) the advertisement which lacked a rating could be as attractive due to cultural interpretations of white spaces..

Vampyr och nagelbitare : En genre- och diskursanalys av barn- och ungdomsrysare och deras ämnesord

This master's thesis in Library and Information Science examines how the genre division of the horror fictionis constructed at the children and youth department of a library by studying subject headings of the titles.The aim is to examine what is included in the genre, in the two labelings called vampire and nail-biter/spine-chiller, what separates them, and what difference there is between children and youth thrillers/horror fiction. Also the cover designs and how readers portray these books are studied. The study is made in order to develop the knowledge of the genre to help librarians and borrowers. The great popularity of the genre among borrowers and people in general, and the importance of having knowledge of things that borrowers are interested in, are the motivation of performing the study. The method is a case study and conducted with and based on genre theory which shows how a genre is defined, how it can be divided and what conventions there are for the horror fiction in particular.

Att kommunicera idéer och visualisera information i 3D :

In order to respond to a more complex community planning with increased cooperation and public participation, a common language and a common model to be used as a base for the communication process is needed. The thesis behind this dissertation for a master's degree is that a virtual 3D planning portal would respond to this need. Why and how are explained and described through studies of communication- and perception theory as well as technology and recent research. The introduction concludes that a broad participation and a transparence towards underlying information are important foundations for the coming work with the model. The first four chapters of the theory part show the benefits of using natural signs in our mixed cultural society, instead of the more arbitrary symbols. Using visual landscapes for storing information is motivated by the flexibility of our visual memory and its ability to understand complex connections.

Muddring i Ireån : indirekta effekter på bottenfaunan nedströms

This research aims to investigate the effects that dredging may have on benthic fauna. The dredging took place in the stream Ireån on northern Gotland during the early summer 2010. My area of research was taking place in a scenic area downstream in Ireån close to the Baltic Sea. I chose this area due to the dredging that started just upstream of this area and continued further upstream. Thus it is not the direct impact of the dredging that is the focus for this paper but the side-effect the dredging may have on the area downstream.

Skogsbränslets fraktionsfördelning

This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..
