Adhesion av mikroorganismer till lignocellulosa

The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.

Rengöring, desinfektion och förvaring avendoskop i djursjukvården

With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..

Barns föreställningar om de första djuren som utvecklades på jorden

Omvärldsanalys av Sveriges ekokommuner

Miljöfrågorna och miljöarbetet har förändrats under de senaste åren och det har blivit uppenbart att något måste göras för att begränsa människans miljöpåverkan. I Rio, 1992 hölls FN:s konferens för hållbar utveckling och grunden för det internationella tänkandet om det ?uthålliga samhället? lades och gav genomslagskraft även i Sverige. Sveriges Ekokommuner är en ideell förening som jobbar för att utbyta kunskap, kompetens och erfarenheter inom ramarna för en hållbar utveckling och det uthålliga samhället..

Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

"Den svage bland oss"

The purpose of the thesis is to examine the thoughts and opinions of a selected group of people regarding the terrorist attack that occurred in Stockholm 12/11-2010. This study has been conducted through the method of focus group interview. The study was methodologically and theoretically inspired by Grounded Theory, which simply means that the participants' opinions have formed the theory of the study. As a result of the study, we can see that the main focus of the discussion held by the participants was through a we and them thinking-perspective. Furthermore, the study reveals that the participants tried to include who we (muslims) are, and to exclude who they (non muslims) are, while arguing in the discussion. Another definition is the one of here and there, where the participants defined terrorism and what causes it. Finally, media's role was discussed in relation to the creation of the medie-muslim. To explain the participants' perceptive, part of Appadurai?s Fear of small numbers and part of Brune?s Dark magic in the white media was used..

Automation i Distributionsnät

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

Design och utvärdering av stridssystem med fokus på meningsfulla val

Syftet med detta arbete är att designa och utvärdera ett stridssystem för ett rollspel, som skall ha en högre grad av meningsfulla val än de två kommersiella rollspel som utvärderas tillsammans med det egenutvecklade stridssystemet. För att få en högre grad av meningsfulla val så designas stridssystemet efter två teorier: triangulära val och multiple-dice systems. Graden av meningsfulla val utvärderas genom strukturerade intervjuer där respondenterna svara på en enkät.Utvärderingen visade att det egenutvecklade stridssystem inte uppnådde en högre grad av meningsfulla val än de två kommersiella stridssystemen.Rollspelet bör i framtiden modifieras för att korrigera de problem som framkom genom utvärderingen. Utvärderingsmetoden som användes i arbetet kan utvärdera graden av meningsfulla val i alla typer av spel..

Framtida användningsområden för materialadderande tillverkning : En studie i hur materialadderande tillverkning kan användas i rymden

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..
