Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips

Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of stump are probably of great importance to make it accepted as fuel. It is therefore rewarding to carry out an investigation in this area for stump. This report represents results from a diploma project, which was aimed to develop a fixed bed reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic modelling employing Ozawa method and different kinetic models including one-step and three-pseudo-component models.

Utökad samverkan med leverantörer : - Partnering, en lönsam möjlighet i byggindustrin?

The construction industry has been heavily criticized in the past few years for its development of productivity compared to the manufacturing industry. In 2009 the Social Care Center developed a report that treated och criticized different errors within the construction industry. For instance competence, construction errors and performance had showned bad results which had to be improved. A common sentence within the building industry is that ?every project is unique?. Today it?s common for a construction company to have costs for material and services which exceeds two-thirds of the total cost.

Stamningsbehandling enligt Lidcombeprogrammet : En långtidsuppföljning av svensktalande förskolebarn

The aim of this paper is to study the long-term effects of stuttering treatment according to the Lidcombe Program in Sweden and to answer questions whether underlying factors may have affected the treatment results. Participants were seven children, one girl and six boys aged 7:10-14:2, who all completed Stage 1 of the program approximately 2-7 years ago.The children were video recorded during a conversation with one of the authors and while reading aloud. Before the recording, their parents estimated the level of stuttering according to a Severity Range (SR) Scale. The evaluations were used as reference for determining whether the recordings were representative for the children´s current speech fluency. Proportions of stuttered syllables (%SS) were calculated from the video recorded material and compared with the proportions of stuttered syllables (%SS) at the time when the first stage of the program was initiated.The results showed that the Lidcombe Program had a significant (z=-2.37, p=0.02) long term effect on stuttering treatment for the participants in this study.

Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

Bistånd och korruption : Hur hanteras korrupta regimer av biståndsgivare?

Bachelor essay in political science by Linus Johansson, fall of 2006?Aid and corruption: How do aid donors handle the corrupt regimes??.Supervisor: Jan Olsson.The purpose of this essay is to describe the aid relation between donors and corruptgovernments, to find out whether donors reckon on the problems with implementation of aidto corrupt governments when they decree their aid policy. There are a lot of different ways toimplement the economic aid that are being used by the donors today, and this essay will try toexemplify the different methods of implementing the economic aid. To elucidate the relationbetween donors and corrupt regimes, the essay analyzes three themes: the first two questionsare about the policies used by the donors, and the third question are used to shed light on theactual implementation of aid to corrupt governments. The three themes are: i) Different aidpolicies used by the donors ii) Do donors use particular policies against corrupt regimes? iii)Do corrupt regimes receive less foreign aid? This study stresses the fact that donors do notact like a group unit in the matter of development assistance policy, instead they act inseveral separate groups, this may complicate the endeavour of making economic aid effective.The conclusion of the essay is that corrupt governments are treated the same way that lesscorruptedgovernment are, nothing today indicates that donors would give less economic aidto the corrupt regimes.

EFFEKTER AV STABILITETSTRÄNING I FOTLEDEN EFTER SKADA : EN LITTERATURSTUDIE

Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.

Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Hellre sjuk och mager än frisk och fet : En litteraturbaserad studie av kvinnors upplevelser under behandlingen för anorexia nervosa

BackgroundAnorexia nervosa is a growing problem in society and it is most common among women. It is a complex disease that affects both the mental and the physical health. The disease expresses itself differently from person to person, therefore, treatment should be individualized. Nurses need to gain insight into how patients feel about the treatment in order to understand their experience. Previous studies use statistical research to evaluate treatment.

Träning av motorisk/postural kontroll

Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.

Förskolan, en arena för fysisk aktivitet! : Pedagogers uppfattningar av sitt arbete med fysisk aktivitet i förskolan

AbstractThe aim of this essay is to understand the view of man as a creature in the Norse culture by studying rituals and ritual actions in conjunction with homicide. The material on which the study is based is called the Icelandic sagas, which are important source of information to the Norse culture. To achieve the purpose, I used a qualitative content analysis and qualitative narrative analysis along with ritual theories based on Roy A Rappaport among others. The questions are for instance:- What ritual actions occur in connection with the homicide, according to the Icelandic sagas? - What are the differences in how individuals are treated in passages where the ritual actions in relation to homicide and homicide cases investigated and why?The results show four different types of ritual acts in relation to homicide.

Intellectual Property Rights : A Barricade to Technological Development. An Ethical Analysis on the Less Developed Countries

Debate over Intellectual Property Rights ?IPRs? particularly patent and copyrights is mainly on forward-looking industries in computer software. As part of a trade deal reached in 1994, the member nations of the World Trade Organisation must adhere to a global agreement known as TRIPS, for the Trade- Related Aspect of Intellectual Property Rights.This study is to analyse the ethical conception of Intellectual Property Rights and in particular its implications on the developing countries in relation to TRIPS. The approach will be to analyse a broad philosophical theories of property to see if there is any justification for a software program to be treated as private property and also argue base on John Rawls two principles of justice in relation to TRIPS Agreement. Some reflections will be put on the use of open-source software by less developing countries.From the study it was asserted that, strong IPRs protection would hinder technological transfer and indigenous learning activities in the early stage of industrialisation when learning takes place through reverse engineering.
