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.
Optimerande av gasanläggning - genom värmeåtervinning och förlustreducering. Gässlösa Reningsverk
The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.
Beredning av lokalnät i landsbygd
In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.
Digital utsläckning av sinussignal
Detta examensarbete utröner möjligheten att aktivt släcka ut en amplitudstark frekvensmodulerad sinussignal digitalt. Detta skall göras utan förkunskap om signalen gällande fas, frekvens eller amplitud. Eventuellt övriga, men betydligt svagare, sinussignaler i den analoga signalen skall inte påverkas nämnvärt av utsläckningen. För att lösa problemet har olika teorier för att lösa delproblemen med att mäta amplitud, fas och frekvens studerats varefter en lämplig kombination valts för implementering i en FPGA. Prestandan som uppmätts har jämförts med vad som teoretiskt är möjligt och vi konstaterar att metoden löser problemet på ett adekvat sätt men är i behov av en del förbättringar som diskuteras i slutet..
Dorsalflexion i första metatarsalleden och naviculare position hos motionärer med Achilles tendinopati i mittportionen
SammanfattningSyfte och frågeställningar: Syftet med denna studie var att a) undersöka om motionärer med Achilles tendinopati (AT) i mittportionen har nedsatt dorsalflexion i första metatarso- falangealleden (MTP 1-leden) på affekterad sida jämfört med frisk b) undersöka om det finns sidoskillnader i naviculare position samt c) undersöka vilken metod - goniometermätning (GM) eller visuell estimation (VE) - som är att föredra vid mätning av dorsalflexionen i MTP 1-leden. Frågeställningarna var följande: Hur förhåller det sig med skillnaden för dorsalflexion i MTP 1-leden då affekterad sida jämförs med frisk hos motionärer med AT? Hur förhåller det sig med sidoskillnaden för fotvalvets höjd ? Hur förhåller det sig med sidoskillnaden för den vertikala rörligheten i mellanfoten? Hur förhåller det sig med mätvärdet för dorsalflexion i MTP 1-leden då affekterad sida jämförs med frisk vid användandet av respektive mätmetod (GM och VE)? Hur förhåller det sig med den samtidiga validiteten mellan VE och GM vid mätning av dorsalflexionen i MTP 1-leden?Metod: 28 patienter med unilateral AT (medelålder 39 år, symtomtid median 12 veckor), rekryterades konsekutivt. Patienterna diagnosticerades kliniskt, nedre extremitet screenades för rörelseinskränkningar i sagittalplanet, naviculares höjd (NH) mättes i två positioner och naviculare drop (ND) beräknades. MTP 1-leden fotograferades tre gånger i standardiserad mätposition och dorsalflexionen mättes med GM på fotografierna som randomiserats.
Carbon sequestration in the pastoral area of Chepareria, western Kenya : a comparison between open-grazing, fenced pastures and maize cultivations
Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).
Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia
There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.
Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde
The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..
Studenters förhållande till etik och moral vid köp : CSR vid konsumtion
The purpose of this essay is to analyse and understand how students, as consumers, choose brands from the aspects of the concept of CSR, the economic, social and environmental. The essay is based on a qualitative method with three focus groups, with five respondents in each of them. The respondents are all studying at Kalmar University and they have all studied some kind of economic-course. We have used a lot of different sources for our theory chapter, this because of the fact that we wanted to have different angles, so that we would be able to cover all of the questions we wanted to discuss in the focus groups. In our two final chapters we discuss the issues similar to the theory section and we highlight our own thoughts.
Åldersbedömning av maskerade ansikten -Precision och systematiska fel
Syftet med föreliggande studie var att undersöka hur bra vi är på att bedöma ålder på omaskerade och maskerade ansikten. Syftet var även att undersöka om det fanns systematiska fel som är förknippade med åldersbedömning av maskerade ansikten.Totalt fick 60 försöksdeltagare, samtliga ungdomar, skatta åldern på 60 fotografier av 30 maskerade och 30 omaskerade män. Fotografierna var indelade i två åldersgrupper, yngre och äldre, och samtliga stimulipersoner förekom i både den maskerade och den omaskerade varianten.Resultaten visade att försöksdeltagarna var bättre på att skatta åldern på omaskerade ansikten än på maskerade. Inga skillnader i systematiska fel fans mellan maskerade och omaskerade ansikten.Bilder av unga ansikten skattades med högre precision än bilder av äldre ansikten..
Shys metod för att mäta byteskostnader - en kritisk granskning
This thesis? objective is to evaluate the recently proposed Shy (2002) approach of estimating consumer switching costs. We apply Shy?s method for estimating switching costs on the Swedish markets for bank deposits and telecommunications. The evaluation has been achieved by comparing estimated results to economic theories, related empirical studies, and our expectations.
Utvärderande bibliometri: en jämförelse mellan två kvalitetsindikatorer
This master's thesis aims to explore the field of evaluative bibliometrics. In short, this field of research uses bibliometrics - i.e. the application of mathematical and statistical methods to books and other media of communication - as a research assessment tool. In recent years, evaluative bibliometrics has been an increasingly used method in research evaluation and is today used and implemented in many countries worldwide. Today, in Sweden, we can also see that evaluative bibliometrics is highly recognised and, in some cases, used in practice.
