Fuel ethanol can be produced from lignocellulosic materials to replace gasoline and diesel. A crucial step in the production process is the hydrolysis (saccharification) of the material, which can be achieved with dilute acid at high temperature. Unfortunately, sugar is degraded under these severe conditions, and the sugar yield is generally low. This thesis deals with countercurrent operation, wh
The timing of the ice margin retreat of the Late Glacial Patagonian Ice Sheet (PIS) in southern Patagonia has been the object of discussion for many years. In order to resolve questions about the complex response of the PIS to past climate change, any geological interpretation and data modelling need evaluation against an absolute chronology. The aim of this project is to investigate the applicabi
Brown C, Hasson H, Thyselius V, Almborg A-H. Post-stroke depression and functional independence: a conundrum. Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2011.01595.x. © 2011 John Wiley & Sons A/S. Objectives - People who suffer a stroke are at risk of developing post-stroke depression (PSD). Not only does this lower their quality of life but it also increases their risk of another stroke or d
BACKGROUND: Galectins, a family of small carbohydrate binding proteins, have been implicated in regulation of inflammatory reactions, including asthma and fibrosis in the lungs. Galectins are found in cells of the airways and in airway secretions, but their glycoprotein ligands there have only been studied to a very limited extent. METHODS: Bronchoalveolar lavage (BAL) fluid from mild asthmatics a
Purpose: The purpose of this paper is to examine and explain what organizes the marketing of retail sustainability. Design/Methodology/Approach: Theoretically, this paper takes a marketing-as-practice approach and makes use of practice theory to conceptualize the marketing of sustainability. Methodologically, an ethnographic study of three Swedish retail chains and their marketing work has been c
Many novel pharmaceutically active substances are characterized by a high hydrophobicity and a low water solubility, which present challenges for their delivery as drugs. Tablets made from cross-linked hydrophobically modified poly (acrylic acid) (CLHMPAA), commercially available as Pemulen™, have previously shown promising abilities to control the release of hydrophobic model substances. This stu
This paper presents the results of combined investigation of the chemical bond formation in fluorinated multiwalled carbon nanotubes (MWCNTs) with different fluorine contents (10-55 wt %) and reference compounds (highly oriented pyrolytic graphite crystals and "white" graphite fluoride) using x-ray absorption and photoelectron spectroscopy at C 1s and F 1s thresholds. Measurements were performed a
Abstract Between 1989-1996 and 2000-2003 a civil war took place in Liberia. During the war many, many people were killed or were forced to flee. Another of the war's characteristics was the high number of women being sexually abused and beaten by the soldiers. The aim of this thesis is to analyze to what degree the peacekeeping personnel in Liberia, foremost staff working for the UN and agenc
This thesis examines the origin of social capital from an institution-centered approach, in order to find whether the Public Administration and Decentralization Reform can increase social capital in Cambodia. Apart from this empirical aim, the theoretical ambition of the thesis is to test a Western-based theory on an untried setting and to develop the theory if it proves not applicable. The thesis
A powerful cartel forces customers to pay significantly more for products and eliminates competition since its participants do not need to improve their productivity or the quality of their products. Cartels have historically exercised great influence over the international economy. During the inter-war period cartels were so powerful that economists have estimated that international cartels contr
The issue of possession of the air has been debated over literally thousands of years. The Romans debated the ownership of the air above their cornfields. When man finally could construct aircraft, in this case a balloon, heavier-than-air in the 1780's it did not take long before the first regulation came into force. The issue of state sovereignty had been discussed since the national states s
This is a thesis report for the Master’s program in Risk Management and Safety Engineering at Lund University. It is also a part of the research project Assessing acceptance of privacy-invasive ICT Solutions at the Royal Institute of Technology. Its aim is to examine how the perception and acceptance of privacy-invasive technology is determined by demographics, context and cognitive factors. The m
Interference fit assembly is a state-of-the-art technology for mounting cylindrical shafts into bores. Due to its extreme cost-efficiency it is used even in high-tech applications such as one of Bosch’s gasoline flow controllers. The picture below shows the anchor-needle connection. Due to electromagnetic incitation the assembly oscillates over 55 times per second. In order for the assembly to wit
The society of today is undergoing two different trends in government and governance. The first reflects the internationalization and globalization towards a multicultural society where an increasing numbers of measures are being assigned to international and supranational levels. The second tendency is decentralization and an emergence of strong local and regional politics. This is although not s
This is a Master Thesis carried out for and done in cooperation with Getinge Water System A/S. The purpose of the thesis was to develop a new separation system for their Pure Steam Generator. The focus was set on making it smaller without affecting separation efficiency and manufacturing costs. During the projects course, objectives were altered and size was no longer highly prioritized; instead,
The purpose of my study was to examine how people talk about their sibling position. I wanted to find out how we present ourselves as siblings, rather than establish one for all valid truth. In the study I explored whether people believe their birth order has affected them and if so, with what consequences. I conducted a qualitative study using twelve interviews and analyzed the material with a so
The trend among mobile phones of today is that they are getting smaller at the same time as they are stuffed with more and more functions. As a consequence the phones become more complex and difficult to handle for many users, particularly for people with some kind of physical or cognitive limitation. Still these persons have a need and desire to be able to communicate with their surroundings. The
The aim of the study was to evaluate care given at a diabetes foot clinic from the patient's perspective. A comparison between Swedish- and foreign-born patients with severe diabetic foot ulcers/problems concerning their experiences of the content and organisation of health care was made. A qualitative, descriptive study design was chosen and a consecutive sampling procedure was used. Fifteen
The research for this study, concerning trade unions within the maquila industry, has been carried out during a three months period in the Central American country of El Salvador. Fieldwork and research has been financed by the MFS (Minor Field Study) scholarship of SIDA. Research questions used throughout the field study have focused on the possibility of unionization and the role and position of
Abstract This study deals with the theory of the social capital and the addiction of cannabis. Social capital is a theoretical perspective with no specific concept. The aim was to compare the definitions of friendship and the addiction of seven law students. The purpose of this paper, with the support of the theory of the social capital, was to investigate the students’ reactions and how they act
