AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Medarbetarskap och Human Resource Management i en Telekomkedja

Två begrepp som ofta diskuteras inom organisationsteori är Medarbetarskap och Human resource management. Personalen ses ofta som ett företags främsta resurs. Denna uppsats bygger på en kvantitativ undersökning bland personalen inom en Telekomkedja. Vårt syfte är att bringa klarhet i frågan om i vilken utsträckning det ?myndiga medarbetarskapet? existerar, hur olika strategiska åtgärder påverkar försäljningen, vad som påverkar medarbetarnas motivation samt hur deras lojalitet gentemot arbetsgivaren ser ut.Undersökningen visar att personalen i Telekomkedjan trivs bra på sin arbetsplats.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Pellets - en framtidsmarknad?

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.

Dynamiken hos ett EU-system för handel med gröna elcertifikat

In electricity markets evolving towards liberalisation and internationalisation, green certificates are seen as an important tool to promote production of renewable energy. In a green certificate market producers sell certificates received per unit of electricity generated from renewable energy. Trade in renewability is thereby decoupled from the the physical electricity trade. Tradable green certificates in combination with renewables obligation are implemented or planned in several EU member states. Integration at EU leveland the creation of a common certificate market seem like a possible next step.

Gröna utsikter : En analys av hampas (Cannabis sativa L.) förutsättningar som energigröda i Sverige

Hemp is a versatile plant with many uses that has been around for thousands of years. The plant is highly adaptable andwill cultivate in almost any soil. It has excellent remediation properties and has shown to be relatively consistent when itcomes to crop yields. The aim of this literature survey is to examine how hemp can be used to be considered asustainable energy crop in Sweden through database searches and interviews. Hemps characteristics as an energy cropand its remediation properties is evaluated and compared with other plants that are used in Sweden.

Kariesprevalens i Irak och Sverige - en jämförelse och analys av faktorer

Som tandhygienist är det mycket intressant att studera karies-epidemiologiska undersökningar på både nationell och internationell nivå. Syftet med denna litteraturstudie är att beskriva och jämföra kariesstatus (DMFT) hos 12-åringar i Sverige och Irak, och några av de faktorer som kan påverka DMFT komponenternas roll och inverkan. För att besvara syftet användes information från litteratur och tidskrifter samt WHO:s databas om länderna. Resultatet visar att DMFT för 12-åringar i Irak var 1.7 (2003) och i Sverige 1.0 (2005). DT-komponenten, d.v.s. obehandlad karies, var hög hos irakiska barn medan FT- komponenten var hög för danska barn (inga data tillgängliga för Sverige).

Framtidens resurs eller dagens problem? En studie om institutionens syn på ungdomar och dess effekter.

AbstractIn this thesis we analyze how institutions describe the dichotomy between ?problem? and ?resource? when dealing with young adults. We also analyze the consequences of this dichotomy as it involves the younger generation's participation and group identity in today's society. Dichotomies and New Institutionalism Theory is the base for this case study completed in Malmö, Sweden. We have done eight qualitative interviews with politicians and employees in Malmö municipality and a quantitative content analysis of reference documents from both the Malmö and Swedish governments.

Webbsida med WEB 2.0

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

Smart konsumtion : unga vuxnas attityd till miljö- och rättvisemärkta produkter

We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.

VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
