Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ
Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by
Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer
(system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in
terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.
Förvaltningsaktiviteter i verksamhetskritiska IT-system
Avsikten med vårt arbete är att undersöka vilka aktiviteter som en förvaltningsorganisation utför på sina IT-system och om det finns några skillnader i dessa beroende på om organisationen förvaltar åt sig själva eller om det utförs för kunds räkning. Detta som ett led i att ge de som arbetar med, eller kommer att arbeta med, systemförvaltning en inblick i eventuella skillnader mellan förvaltning av egna system och förvaltning av en eller flera kunders system. De slutsatser vi dragit ur denna undersökning är att det inte förekommer skillnader i vilka aktiviteter som ingår i förvaltningsarbetet, däremot varierar det i vilken utsträckning man väljer att utföra dem..
Socialt stöd efter våldtäkt
The focus of this study is on the nature of social support from the rape survivor's perspective. Research has shown that social support is essential to the survivor's ability to recover from rape and that it acts as a powerful tool for the survivor to effectively deal with the PTSD symptoms that follow rape. The research also shows that survivors often receive or interpret reactions after a rape as negative. Hence, these reactions can be detrimental tothe healing process.Qualitative interviews with six women on their experience of social support after rape form the base of this study and Anthony Giddens terms ontological security, fateful moments and bodily self-management are a part of the analytical apparatus. Rape is commonly analyzed from a feminist perspective.
Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines
With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.
Att söva den feta patienten- med fokus på ventilationen
Fetma och övervikt är ett hälsoproblem som drabbar mer än var tionde person och antalet individer med BMI >30 ökar ständigt. Som en följd av detta kommer allt fler patienter som genomgår anestesi att ha ett högt BMI. Förändringar i respiration, luftvägsanatomi och ett flertal andra fysiologiska förändringar i kroppen gör generell anestesi för patienter med fetma till en anestesiologisk utmaning. Syftet var att beskriva vilka omvårdnadsåtgärder anestesisjuksköterskan kan använda för att bibehålla god ventilation hos feta patienter vid generell anestesi. Studien genomfördes som en litteraturstudie där 12 vetenskapliga artiklar analyserades.
Energianvändning i restauranger i Umeå kommun
Efficient energy use in restaurantsUmeå Municipality wishes to combine energy issues with food control, and thus help restaurants to become more energy efficient. During March and April 2010, I visited seven restaurants and interviewed restaurant personnel about current state and application of kitchen appliances, using a checklist to make sure that the same questions were asked at all restaurants. The restaurants were all different sizes and offered different kinds of food. The study mostly focuses on energy efficiency by behaviour and not on location or technology. Almost every restaurant that was visited had the potential to improve in one or more areas, such as kitchen appliances, lamps and lighting fixtures, heating, cooling and ventilation.
IT-system och organisationsutveckling
This report describes work on the thesis ?IT systems and organizational development?. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization.
Vilken funktion har belöningssystemet i en organisations ekonomistyrsystem? : en jämförelse mellan två storbanker
Two of Swedens´s major banks, SEB and Handelsbanken, which appears in the same industry and have similar strategy. Both banks can achieve a similar result despite the fact that their reward system looks quite different. An issue that arises from this observation is the relative reward system to the rest of the economy control system.Our purpose of this paper is therefore to examine the reward system in the organization's financial management systems. We wonder if the reward system may be a function of economic control system, or part of the system, or perhaps made independent of the system and then gradually adapted?In our study, we choose to assume a reward system has three functions to manage, motivate and compose the employee group.
Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal
SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.
Eldistribution på offshoreenheter -Jämförelse av AC- och DC-anläggningar
Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.
Släpslangspridning av gödsel, kan det löna sig? :
I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has.
The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time.
I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today.
What is drag hose system?
You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.
Inverkan av foders växtöstrogener på fysiologiska processer hos produktions- och sällskapsdjur
Phytoestrogens are secondary metabolites produced by plants. Among the plants that make phytoestrogens are soya, red clover and some types of grass. The name phytoestrogen is a collective term for compounds such as genistein, daidzein, biochanin A and formononetin. These compounds are similar to oestradiol-17? in their chemical structure.
