Utveckling av en beräkningsmodell för biogasproduktion
A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.
Skogspolitik i Sverige
For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.
Månadskostnader vid investering i ny bostad : En jämförelse av olika investeringsalternativ och deras ekonomiska påverkanvid införskaffning av ny bostad.
This is a work that look at the factors that affect future monthly costs when buying a house in Sweden and which options are the most financially favorable over a 30 year period. The work also examines whether it is economically beneficial to invest in a low-energy house regardless of geographic location in Sweden, and discuss about whether a calculation template can help individuals to choose more environmentally friendly options. The work has been limited so that a certain number of predetermined factors and its measurable values have been developed with the help of a literature study. The factors chosen are building type, climate, heating systems, loan interest rates, energy prices, energy price increases, inflation rates and down payment. These are then combined into 72 different calculation cases which get put in a calculation model made in excel.
Lean Production i den offentliga sektorn : Hur kan Lean Production påverka medarbetare att jobba med ständiga förbättringar och kundvärde?
AbstractTitle:Lean Production in The Public SectorsLevel:Final assignment for Master of Science in Business Administration.Authors:Simon Mårtensson and Ramnpreet Kaur MaanSupervisor:Stig Sörling and Tomas Källquist.Examiner:Lars-Johan ÅgeDate:2015 ? June.Aim:The use of Lean Production in the public sector is increasing and there are still opportunities for improvement that contributes to a higher customer value. According to previous research that has been done, there is a lack of research in the field of Lean production in the public sector. Thus, the aim of this study is to create an understanding of how Lean production as a concept can help to influence employees to work with continuous improvements and customer value in the public sector.Method:The study has a hermeneutic perspective as a starting point where the substance is studied from an operator approach. We have chosen to build our study with the help of deduction starting with a theoretical framework and then go into the empirical framework.
Planering av väginvesteringar :
The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent.
Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.
Positive human to cattle interactions and the possibilities to increase animal welfare, economy and safety for farmers
Cattle production systems are changing to bigger intensified systems with larger numbers of animals per farm and more free range systems while at the same time employing fewer people. Aversive handling has been known to affect cattle production negatively for many years, but lately scientists have started to focus more on what positive effects gentle handling and positive human-cattle interactions may have on beef and dairy production. Fear can cause high stress in production animals and this can contribute to not only reduced production within beef and dairy cattle, but also increased risks for accidents and decreased animal welfare. Therefore, by reducing the fear cattle experience of humans, it could be possible to increase production, decrease accidents and increase the welfare of the animals. Reducing the animals fear and stress can be done by simple means, such as walking and talking calmly around the cattle, associating humans to positive feelings (such as feed) and stroking the cattle?s body regions associated with social grooming.
Hur ekonomin i svinproduktion påverkas av prisförändringar :
The purpose of this essay is to evaluate how the big changes in prices are effecting
pigproduction. My calculations show how much there will be left for interests and
amortisation. I?ve chosen not to calculate the costs of buildings.
The condition from the beginning is a production of pork with 10.000 pigs per year.
Instead of buying piglets, I?ve calculated on breeding them and for that purpose I will
need 440 sows.
I?ve investigated the working hours and given examples of how to decries these.
My conclusion is that with the prices we have to day, pork production is a hard
business..
Att finna balansen : En kvalitativ studie om Lean Production och det pedagogiska ledarskapet
Denna uppsats undersöker hur ledarstilen påverkas av anammandet av filosofin inom Lean Production. Syftet är att granska hur ledarna kan kombinera dynamiken bakom ett pedagogiskt ledarskap och medarbetarnas medinflytande med principerna inom Lean Production. Vår uppsats bygger på den empiri vi samlat in genom sex kvalitativa intervjuer med både ledare och medarbetare på tre avdelningar inom tre olika organisationer. De teoretiska utgångspunkter vi använt oss av grundar sig i huvudsak på Arne Malténs dimensioner kring ett pedagogiskt ledarskap. Analysen är sedan strukturerad kring dessa dimensioner.

The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.
Registrering och avel för brunstvisningsförmåga hos mjölkkor
Dairy farmers using artificial insemination (AI) are dependent on effective oestrus detection. In Sweden, AI is used for a majority of all dairy cows and oestrus synchronisation with hormones is not allowed. There are reports of declining ability to express oestrus with higher levels of milk production. This makes oestrus detection more difficult. Several aids for oestrus detection have been developed, for instance pedometers and mounting detectors.
