The movement of plants, animals, and microorganisms by humans, consciously or unconsciously, has changed both ecosystems and societies throughout history. This article focuses on one such transformative species, lodgepole pine, and its relocation from northwestern America to northern Sweden in the mid-twentieth century. A cultural biography of the lodgepole pine’s existence in Sweden examines how
District heating and cooling systems have been undergoing continuous development and have now reached the fifth-generation. In this innovative technology, connected buildings share local excess energy that otherwise would be wasted, which consequently reduces primary energy demands and carbon emissions. To date, the issue of implementing fifth-generation district systems on existing buildings has
This study has analysed which options would be appropriate to use as additional requirements to the main requirement of primary energy number in the new Swedish building regulations. The starting point is to ensure that buildings are built with good qualitative properties in terms of the building envelope so that low energy use can be maintained throughout the life of the building despite changes
Displacement ventilation is a proven method of providing conditioned air to enclosed spaces with the aim to deliver good air quality and thermal comfort while reducing the amount of energy required to operate the system. Until now, the practical applications of displacement ventilation have been exclusive to providing ventilation and cooling to large open spaces with high ceilings. The provision o
This investigation consisted of developing and evaluating solar dryers together with semi-permeable membrane pouches for drying juicy fruits in low-income tropical countries. Two design iterations were carried out including prototype modelling and testing. The latest developed solar dryers were a passive and an active solar dryer. Modelling was initially carried out mathematically using an equatio
Leonardo da Vinci Community Vocational Training Action Programme’s pilot project within Geographical Information Science (GIS), should be implemented over a three year period, 2002-2005. The main objectives of the project is to establish co-operation between European Universities and GIS user organisations and to develop modularised courses intended for Internet based learning, establish links of
Galectin-4 is a tandem-repeat galectin with two distinct carbohydrate recognition domains (CRD). Galectin-4 is expressed mainly in the alimentary tract and is proposed to function as a lipid raft and adherens junction stabilizer by its glycan cross-linking capacity. Galectin-4 plays divergent roles in cancer and inflammatory conditions, either promoting or inhibiting each disease progression, depe
One of the generic learning outcomes to be achieved by science students at Lund University is the ability to communicate science also to a non-specialist audience. In this report we analyze popular science papers written by undergraduate students of biology. The aim is to investigate the quality of the observed learning outcomes of a course in communicating with the general public. Through textual
BackgroundDimethyl sulfoxide (DMSO) is essential for the preservation of liquid nitrogen-frozen stem cells, but is associated with toxicity in the transplant recipient. Study Design and MethodsIn this prospective noninterventional study, we describe the use of DMSO in 64 European Blood and Marrow Transplant Group centers undertaking autologous transplantation on patients with myeloma and lymphoma
Children should not be exposed to unwanted chemicals in their everyday life and several organizations in Sweden are working towards reducing the amount of chemicals that exists in toys and material intended for preschools. Many municipalities are joining the project, and are now working towards the goal “toxic free preschools”. In this struggle the municipalities have an impact in their procuremen
This essay explores whether there is a connection between geographical location and degree of socioeconomic inequity in children’s health status in Zambia. It looks at, to what extent a difference can be seen in the socioeconomic health gap between rural and urban areas and between primarily rural administrative provinces and primarily urban ones. The questions examined here are: 1) Does geographi
Människohandel för sexuella ändamål är ett komplext fenomen och ett globalt problem som både berör och upprör. Människohandel är gärningar som syftar till ett efterföljande utnyttjande av offret och ett brott där skyddssyftet är personlig frihet och frid. Det är också ett sammansatt problem, det vill säga att det innefattar bland annat brott mot mänskliga rättigheter, organiserad brottslighet, migHuman trafficking for sexual purposes is a complex phenomenon and a global problem that upsets. Human trafficking is an acts aimed to subsequent exploit the victim and a crime which aim the protection of personal liberty and peace. It is also a complex problem, that includes human rights violations, organized crime, migration, gender, poverty and social, economic and political differences between
The point of departure for this Master’s thesis is twofold. First, the authors notice an apparent shift in focus, from collections towards the audiences, which has affected the international museum sector during the last decades. Second, they notice a change in the discourse concerning the cultural sector towards interpreting issues in economic terms. The development of the British method Generic
This Master’s thesis is set to study why art historical museums exhibit their permanent collections in a different way than what is generally more common in natural history and cultural history museums. Whereas art history museums tend to keep their rooms free from voices, natural and cultural history museums tend to (and have for a long while) build up more scenes. I also study how these ways of
In my thesis I present the work of the Japanese artist Takashi Murakami and the British street artist Beejoir, both of whom have done work involving the trademark monogram pattern of Louis Vuitton. Through my analysis of central parts of Murakami's body of work, I show how his cooperation with Louis Vuitton constitutes an ideal symbiosis where the carefree luxury of the Vuitton brand is comple
Corporate Social Responsibility (CSR) har under det senaste decenniet blivit ett allt mer relevant koncept. De flesta multinationella företag (Multinational Enterprises, MNEs) har formulerat uppförandekoder och många har också anslutit sig till internationella initiativ som fokuserar på CSR, som exempelvis Förenta Nationernas Global Compact. Genom globalisering, avreglering, paradigmskiften och inCorporate Social Responsibility (CSR) has during the last decade become an increasingly relevant concept. Most Multinational Enterprises (MNEs) have formulated Corporate Codes of Conduct, and many have also joined international initiatives focusing on CSR, such as the United Nations Global Compact. Through globalisation, deregulation, paradigm shifts and not least the development of information te
An engineer always strive to help in the continuous exploration of the unknown. By doing so we go further out in space and further down in scale. This is the case with microfluidics which in the last years have gotten a lot of attention. This thesis will examine and better try to understand and optimize a fluidic system that uses ultrasonic trapping. Its application may be everything from enrichin
This is the report for a master thesis work which concerns the challenge of automating a reach stacker. A reach stacker is a vehicle that lifts and moves containers. This report should be seen as a preliminary study which handles automation concepts, simulations and sensors. Research questions answered are: Which areas would benefit most from driver assistance, What kind of control is needed for t
All humans are unique, we have different characteristics and we make different decision. This is a challenge when it comes to modelling human behaviour. The models we design are based on mathematics where there is no room for inconsistencies such that are present in human behaviour. So how do we account for this when we try to model human behaviour in evacuation modelling? Most models provide the
A voice prosthesis is a medical device that helps people who have undergone a total laryngectomy to speak again. It is placed in the wall that separates the trachea and esophagus and consists of a valve that opens when speaking. Atos Medical is one of the few companies that manufactures voice prostheses. One of their voice prosthesis models is called Provox ActiValve. A problem with this model is
