Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose
Background and purpose Can an increased focus on values in working life be a factor in stress prevention? Values are defined as the shared principles which guide behaviour in an organisation. The purpose of this study was to describe how patients with musculoskeletal pain perceive the importance of values in relation to coping with daily stress and in relation to health. Methods Patients receivi
When a video sequence is recorded in low-light conditions, the image often become noisy. Standard methods for noise reduction have difficulties with motion. But the interesting parts in a video is often the ones that are moving, for instance a burglar captured in a surveillance video. One approach for denoising video sequences is to use temporal filtering controlled by optical flow, which describ
This Master Thesis will cover the development of the mechanics and design aspects for a new product innovation made for IPsense AB (at Lund Technical University and Ingvar Kamprad Design Center in Lund, Sweden). Due to the sensitivity of the project some information has been left out. The product is part of an IP-based network concept developed for analyzing sound in real time. The total concept
The purpose of this study was to describe and analyze how the Lund municipality works with crime prevention with youths. To perform the study, we interviewed seven people from five different organizations and authorities with different professions and work assignments in Lund municipality. The people we chose were two social workers, one police commissioner, two fieldworkers, one psychologist and
In the future an increasing number of industries will have to comply with greenhouse gas reduction directives. Plans and projects that aim to reduce CO2-emissions are associated with multiple sources of uncertainty and the use of point estimates could lead to misjudgements and erroneous decisions. Within other fields of science uncertainty analysis is a commonly used tool to improve decision basis
‘Green growth’ is a concept that has gained credence in the literature and wider policy-making circles, broadly referring to the implementation of policy and development strategies that encourage economic growth whilst ensuring that environmental wellbeing is maintained and / or improved. However, few examples of ‘green growth strategies’ have been produced to date, and the literature is sparse re
I redogörelser över effektiva åtgärder i arbetet att begränsa ungdomars användande av alkohol och droger hänvisas till forskning som pekar på familjen som den enskilt viktigaste faktorn. Dock lämnas ingen närmre förklaring till varför föräldrarna är det mest lämpade ”verktyget” och ingenstans urskiljs föräldrarnas åsikter om sin medverkan i det preventiva arbetet med barns alkohol- och drogvanor. The aim of this study was to illustrate the parents' perceptions of how the drug prevention work is done when parents participated in parent education "Absolut förälder” and afterwards functioning as "tools", with the mission to influence their children's attitudes to alcohol and other drugs. A qualitative research method was used. The empirical material in the study is base
Diamond Blackfan anaemia (DBA) is a rare, genetically and clinically heterogeneous, inherited red cell aplasia. Classical DBA affects about seven per million live births and presents during the first year of life. However, as mutated genes have been discovered in DBA, non-classical cases with less distinct phenotypes are being described in adults as well as children. In caring for these patients i
Broad public contention against nuclear energy can be observed as a new phenomenon in Japanese society after the 2011 Fukushima Daiichi nuclear power plant accident. This study aimed to identify a sufficient explanation about why the emergence of such a protest movement only occurred after the direct experience of a critical event and did not happen before. Discrediting a sole and simple grievance
The synthesis of series of 1,2,1' substituted bis(diphenylphosphino)- ruthenocenyl (1-4) and ferrocenyl cis-platinum(II) (5-7) and gold(I) (8-12) complexes are described. Crystal structures of 2 and 4, as well as 5, 6 and 10 confirm the molecular geometry of these ligands and their metal complexes. Preliminary investigation of four gold complexes as potential anticancer, antiHIV and antimalaria sh
Today hazard studies are a self evident part of a project plan while creating a new process or making changes in an existing one in the chemical industry. Therefore it is important to make the hazard studies as efficient as possible. The objective for this thesis was to optimise the hazard study processes based on the main methods presently used at Neste Oil Oyj, Neste Jacobs Oy and Borealis Polym
