The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

Bakgrund: Sepsis ?r ett allvarligt tillst?nd d?r kroppens immunf?rsvar reagerar oproportionerligt kraftigt vilket kan orsaka livshotande svikt av vitala organfunktioner d?r tidig uppt?ckt har en betydande roll f?r patientens ?verlevnad. Sjuksk?terskan p? akutmottagningen har en viktig roll i den tidiga identifiering av sepsis vilket ?r ett komplext uppdrag d? sepsis har en diffus symtombild, ett individuellt f?rlopp, och snabbt kan f?r?ndras. Det st?ller krav p? sjuksk?terskans kunskap f?r att kunna arbeta i enlighet med k?rnkompetensen s?ker v?rd f?r att minska lidande och r?dda liv. Syfte: Vilka kunskaper beh?ver sjuksk?terskan ha f?r att tidigt kunna uppt?cka sepsis p? akutmottagningen. Metod: Strukturerad litteratur?versikt baserad p? 12 originalartiklar med b?de kvalitativ-, kvantitativ- och mixad design h?mtade fr?n databaserna PubMed, Cinahl och Scopus. Artiklarna har analyserats enligt Fribergs analysmodell i fem steg f?r litteratur?versikter, och presenteras i tre huvudteman samt ett antal underteman. Resultat: Analysen resulterade i tv? huvudkategorier med tv? subkategorier vardera: 1) Kunskap om befintlig evidens; a) symptom och tecken vid sepsis b) rutiner och screeningsverktyg.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Virkestransporter står för ca 25 % av de totala anskaffningskostnaderna för skogsindustrin. Implementeringen av High Capacity Transports (HCT) i syfte att reducera transportkostnaderna och minska miljöpåverkan för att bibehålla en hög konkurrenskraft för svensk skogsindustri har på senare tid fått ett ökat intresse. Ett av dessa HCT-fordon är ST-kran, där ST står för ?Större Travar? och är en kranbil som utvecklats för rundvirkestransporter med en bruttovikt på 74 ton vilket är 23 % högre än en konventionell 60 tons kranbil. Syftet med detta examensarbete var att undersöka besparingsmöjligheter för rundvirkestransporter genom införande av ST-kran hos Södra Skogs eget åkeri. Studien delades upp i tre faser.

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.
