Mekaniserad plantering med Eco-Planter i södra Sverige :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting.
Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester.
The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive.
The biological output, e.g. planting result and survival rate, seems to be quite good.
Att genom design effektivisera räddningsinsatsen för motorcyklister i trafikolycka
What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..
Befolkningstillväxtens mosaik i Umeå kommun
The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..
Energy analysis of a fruit drying plant in Adeiso, Ghana
The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit
drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying
process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity.
The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.
Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?
In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.
Sjuksköterskors erfarenheter av projektet ?Klinisk bibliotekarie? som arbetsform
Bakgrund: Snabb kunskapsutveckling, ökade krav på kvalité och kostnadseffektivitet inom hälso- och sjukvården gör det viktigt att sjuksköterskor har god förmåga att söka och använda evidensbaserad kunskap. Idag finns ett glapp mellan forskning och klinik. Sjuksköterskor upplever flera hinder till att arbeta evidensbaserat. Under hösten 2010 och våren 2011 pågick ett projekt på ett sjukhus i en stad i mellansverige. Projektet hette ?Klinisk bibliotekarie?, syftet var att höja vårdkvalitén och patientsäkerheten genom att det dagliga vårdarbetet ska bli mer evidensbaserat och att sjuksköterskorna ska känna större säkerhet i att ta fram vetenskapligt underlag för sitt arbete.Syfte: Belysa sjuksköterskornas erfarenhet av projektet ?Klinisk bibliotekarie?.Metod: Studien har en kvalitativ design.
Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk
Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.
Volatiliteten som hjälpmedel vid teknisk anals
Den 1 juli 2007 infördes en ny lag till byggbranschen som innebär att handel av byggtjänster numera ska behandlas med omvänd skattskyldighet. Därav ska inte längre säljare av byggtjänster redovisa moms på sina utgående fakturor utan säljaren ska redovisa både in- och utgående moms. Orsaken bakom laginförandet är den mängd momsfusk som uppmärksammats där säljare av byggtjänster fått inbetalt moms för sina tjänster men inte redovisat den vidare till Skatteverket utan behållt den i egen ficka. Vår uppsats har beskrivit de olika positiva respektive negativa följder laginförandet har medfört..

Vindkraftens framtida scenarier
In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.
Tillväxt hos inkubatorföretag - En fallstudie av SSE Business Lab
Incubators have grown more popular in recent years. Studies have shown that companies that have been part of an incubator grow faster and have a higher survival rate. The Swedish government realizes that this benefits the economy. Therefore they have started different funding programs in order to support the incubators. The thesis aims to explore the underlying reasons for why companies that have been part of an incubator often experience high growth.
Turbinkretspump system - Kraftvärmeverket i Borås
The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.
"Hjälper mig att förstår vad text handlar om" : en undersökning av två skolexterna läxläsningsverksamheter
?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.
TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
