Long-term oxygen therapy and quality of life in elderly patients hospitalised due to severe exacerbation of COPD. A 1 year follow-up study

The aim of this study was (1) to evaluate the effects of long-term oxygen treatment (LTOT) in elderly patients with severe exacerbations of chronic obstructive pulmonary disease (COPD) and hypoxaemia, (2) to study the health-related quality of life (QOL) during hospital stay and at follow-up, (3) to study the safety of an oxygen withdrawal test performed a few days after admission to hospital and

Biologically active metabolites from the basidiomycete Limacella illinita (Fr.) Murr.

In the course of our search for new bioactive compounds from basidiomycetes, four new compounds were isolated from fermentations of Limacella illinita. Illinitone A (1) exhibited weak phytotoxic and moderate nematicidal activities against Caenorhabditis elegans, illinitone B (2) was moderately cytotoxic, while limacellone (3) exhibited weak cytotoxic and phytotoxic activities. The muurolane sesqui

Dynamic Analysis of Harmonics in Electrical Systems

Frequency domain analysis and design of power systems is complicated in the presence of harmonics, switching dynamics, nonlinearities, unbalances, and for systems with mixed ac/dc dynamics. The reason is that linearization of the system does not lead to a time invariant system, but a system with periodically time varying dynamics, which implies that there is coupling between different frequencies.

Life cycle assessment in green chemistry - A comparison of various industrial wood surface coatings

Background, Aims and Scope. Using renewable feedstock and introducing biocatalysts in the chemical industry have been suggested as the key strategies to reduce the environmental impact of chemicals. The Swedish interdisciplinary programme 'Greenchem', is aiming to develop these strategies. One target group of chemicals for Greenchem are wax esters which can be used in wood surface coatings for woo

Role of histidines in the binding of violaxanthin de-epoxidase to the thylakoid membrane as studied by site-directed mutagenesis

Regulation of violaxanthin de-epoxidase (VDE) involves a conformational change at low lumenal pH, followed by binding of the enzyme to the thylakoid membrane. The role of histidine residues in this process was studied by release of unbound enzyme from thylakoids upon sonication, on a pH scale from 4.7 to 7.1. The co-operativity for binding of spinach VDE (four histidines) to the membrane was found

A prospective study on antibody response to repeated vaccinations with pneumococcal capsular polysaccharide in splenectomized individuals with special reference to Hodgkin's lymphoma

Background. Splenectomy is accompanied by a life-long risk of overwhelming postsplenectomy infection (OPSI), mainly caused by polysaccharide (PS) encapsulated bacteria such as Streptococcus pneumoniae. Despite extensive prophylactic efforts the mortality and morbidity rates remain high. The present study was based on a strategy with a predefined vaccination algorithm including repeated 23-valent p

Som man ropar i skogen : Modernitet, makt och mångfald i kampen om Njakafjäll och i den svenska skogsbruksdebatten 1970-2000

Popular AbstractI denna avhandling analyseras den svenska skogsbruksdebatten under nittonhundratalets tre sista decennier. De ideal och värderingar som genom det moderna skogsbrukets ideologi och praktik kom att råda i skogarna utmanades av miljörörelsen från sextiotalet och framåt. Till en början stod skogsnäringen och miljörörelsen mycket långt från varandra, men under nittiotalet började man näIn this dissertation, the Swedish forestry debate during the last three decades of the 20th century is analysed. The contents, values and underlying assumptions of the debate are investigated from a discoursive point of view. Ideals, methods and aesthetics are analysed, as they have been expressed throughout the debate. Modernity's focus on uniformity, order and culturalisation of nature is contra

Optimisation of reflector and module geometries for stationary, low-concentrating, facade-integrated photovoltaic systems

The high cost of photovoltaic modules motivates the use of reflectors to increase the electricity production. The system geometry of static low-concentrating PV systems for building-integration with parabolic aluminium reflectors was optimised for maximum annual electricity production. The optical efficiency of systems with different geometries was calculated from short-circuit current measurement

Smoking and airway disorders in an urban population -special references to gender and socioeconomic status

Popular Abstract in Swedish Delarbetena i denna avhandling, som baseras på en befolkningsstudie från Malmö, studerar sjuklighet och dödlighet associerad till rökning och kroniska luftrörssjukdomar med hänsyn till köns och socioekonomiska aspekter. Studier av män har övertygande visat en ökad mortalitetsrisk associerat med tobaksrökning. Emellertid har endast ett fåtal studier undersökt långtidsefThe Malmö Preventive Project, a preventive, case-finding programme for cardiovascular risk factors and alcohol abuse was created in 1974 at the Department of Preventive Medicine of Malmö University Hospital. Between 1974-1992, a total of 22 444 men (mean age 44 years range 27 - 61) and 10 902 women (mean age 50 years, range 28 - 58) attended the programme, with an overall attendance rate of 70% (r
