Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.

Kronandelsrelaskopering, en ny metod för att fastställa gallringsbehov?

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

Konstruktion av klädhängare för combitech Ab

Företaget Combitech AB hade sedan tidigare tittat på att försöka framställa en klädhängare ämnad åt deras konsulter. Den tänkta produkten skall få konsulten att alltid känna samhörighet till Combitech AB då konsulten befinner sig på uppdrag hos kund. Produkten skall fungera som klädhängare, men också som reklampelare för Combitech AB när konsulten är på plats hos en kund.  Andra sekundära användningsområden är att klädhängaren utgör en så kallad ?give away? produkt på mässor, arbetsmarknadsdagar etcetera för att göra reklam för företaget.Examensarbetet gick således ut på att ta fram tillverkningsunderlag och prisbild för framställandet av två prototyper av en tänkt klädhängare som motsvarade ovanstående önskemål.Arbetsgången började med en konceptgenerarande fas där ett antal möjliga kandidater togs fram. Dessa koncept förfinades sedan i omgångar där beskrivningen av koncepten förbättrades.

Irak : Mellan islamisk identitet och demokratisk process

This is an essay about the political development of Iraq after the overthrow of the Baath regime by the coalition forces in 2003. Almost seven years later, the political scene is still characterised by chaos, even though the country entered a new phase with the adoption of democratic thinking and a new openness to the world. The unstable political situation is a product of inter-ethnic conflict and the interference by neighbouring countries. Iraq is up against two formidable tasks ? building democracy and building a nation.

FASTIGHETSPAKETERING : Alltid ett godkänt förfarande?

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.

Det energisnåla isoleringsmaterialet

This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.

Objektivitet i socialt arbete

Swedish law is very keen on the fact that every person should be treated equal when facing the legal system. When it comes to cases concerning children, social workers and judges are expected to strictly obey the rules of the law but at the same time make individual judgements based on the best interest of the child, something that requires a great deal of empathy and knowledge. Is it possible to live up to the maxim about equality and to simultaneously see the individual needs? With so many different parties and angles in the case, how does one manage to make a solid appraisal of the situation that truly serves the best interest of the child?The purpose of this study was to examine the capability within the social services with focus on objectivity. More specifically it's aim was to find out how the social workers and judges see their capability of being objective in the investigations concerning children.

Common misconceptions about everyday astronomy-related phenomena among students in the 9th grade

Students of all ages host a wide variety of scientifically inaccurate ideas and conceptions about everyday astronomical phenomena, such as the seasons, the moon phases, and gravity. The field of Astronomy Education Research has over the last decade experienced an accelerating growth, although the majority of studies have been conducted in the USA. In this work, the 9th grade students of a typical Swedish school were surveyed by means of a questionnaire in order to probe their conceptual understanding of several key concepts in astronomy. In the end, the number of respondents amassed to a total of 90. The results were analyzed with a constructivist approach in light of conceptual change theory and phenomenological primitives.

Potentiella armeringsfel inom byggproduktionen : En generell studie

Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy.

Bostadsgården : att se till de boende vid utformningen av bostadsgårdar - en litteraturstudie kring bostadsgårdens betydelse

This candidate essay is built on literature studies and discusses the meaning of the residential yard along with what you, as a landscape architect, should think about when you are designing functional residential yards. To do this I found it necessary to figure out what it is that makes people step outside their own apartment and out into the city?s public places. The reasons for this are numerous and many times individually affected. Something that plays a role in people?s outdoor life and prevents them from spending time outside is the lack of time, the technique of today and the feeling off insecurity.
