Den brasilianska nötköttsproduktionens framtida utveckling :

To value the risk and opportunity for our production in Sweden it is necessary to understand the marketing development for beef cattle production in the world. We have chosen to look at the Brazil beef cattle production. They are one of the biggest producers, have good opportunity to develop further and have a big affect at the world market. The method of our work is to gather information from experts of beef cattle production, located in Brazil. We have also gathered information through studies of literature. The factors that will have a big influence at the Brazil beef cattle production during the upcoming years is more efficient land use, lower age of slaughtering and extended use of feedlot-system. Our conclusion is that the Brazil beef cattle will have a sharp increase during the next five years. The amount of pasture will not change during that time.

Annonsmediers miljöpåverkan : när ska miljön få en reklampaus?

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

Infallsvinklar och angreppssa?tt fo?r en svensk livsmedelsstrategi : En utredning av angreppspunkter och betraktelsesa?tt hos livsmedelsstrategi-intressenter samt ha?llbarhetsaspekter av dessa.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet

There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes. District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption Research), which has focused on climate adaption in the Nordic countries.

Analys av planering inom byggproduktion. Hur kan förbättring ske med hjälp av slututvärdering och återkoppling?

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?

Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

Funktionell validering av mutation i PUS-1 i en patient med mitokondriell sjukdom

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.

Affärsupplägg biobränsle Västerbotten : en undersökning av större biobränsleanvändares syn på biobränslemarknaden i Västerbotten

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.

Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Energikartläggning av Försäkringskassans lokaler : rekommendationer för ett fortsatt energieffektiviseringsarbete

With new energy directives in place, the Swedish Social Service (SSS) stands beforethe challenge how to reduce the energy demand in its locales. It is a complex matter,as the locales are rented from various property owners and it becomes a question ofhow to reduce the operational electricity and influence the property owners to workmore with energy efficiency. This thesis takes a balanced research approach in threeparts. Firstly a qualitative part in form of interviews with personnel at the SSS and itsproperty owners, secondly a quantitative part of descriptive nature in form of energystatistics and thirdly a literature review of Energy Management (EM) Supply ChainManagement(SCM), Green Supply Chain Management(GSCM) and EnviromentalPerformance Indicators (EPI). This in order to be able to give normativerecommendations of how the SSS should act to reduce its energy consumption in itslocales and provide new insights on how EM, SCM, GSCM and EPI can be applied ineffect.

Analys och kvantifiering av energieffektivisering inom fjärrvärmesektorn

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects district heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for district heating customers to invest in energy efficiency measures.Result of the Excel model shows that the district heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.
