The increasingly apparent environmental problems in our surroundings necessitate a quest for sustainable development in all areas of human endeavour. Within the field of chemistry and the production of chemicals, the focus is increasingly on the development of green chemistry. This discipline aims to reduce environmental impact by replacing petrochemical raw materials with renewable feedstock and
The Homogeneous Charge Compression Ignition (HCCI) principle holds promise to increase efficiency and to reduce emissions from internal combustion engines. As HCCI combustion lacks direct ignition timing control and auto-ignition depends on the operating condition, control of auto-ignition is necessary. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, a fast
Background: Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence. Methods: In a prospective study at Malmo University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sphin
The aim of this study was to characterize the reversible cerebral uptake of morphine in the pig by measuring the changing arterio-venous plasma concentration gradient over the brain. Seven pigs were anaesthetized by continuous infusions of ketamine and pancuronium and ventilated with oxygen in nitrous oxide. During and after 5-min intravenous infusions of morphine hydrochloride, blood samples were
Objectives: Sentinel surveys in Bissau, the capital of Guinea-Bissau, have shown low prevalence of HIV-1 but high HIV-2 prevalence before 1998. Guinea-Bissau experienced a civil war in 1998-1999. To examine specifically the trends of HIV prevalence from antenatal surveys in Bissau, Guinea-Bissau in 1987-2004, and whether the civil war in 1998-1999 could have an effect on HIV prevalence levels afte
Thylakoids isolated from tobacco were fragmented by sonication and the vesicles so obtained were separated by partitioning in aqueous polymer two-phase systems. By this procedure, grana vesicles were separated from stroma exposed membrane vesicles. The latter vesicles could be further fractionated by countercurrent distribution, with dextran-polyethylene glycol phase systems, and divided into two
The aim of this study was to 1) examine the occurrence and burden of side effects over time in the period after post surgical adjuvant radiotherapy in women with breast cancer and 2) explore the women's experiences of given information and need of support to handle side effects. MATERIAL AND METHOD: 171 women with breast cancer receiving post-surgical adjuvant radiotherapy completed a questionnair
The purpose of this study was to create and evaluate personalised virtual learning spaces (PVLSs) in a course that was previously delivered face-to-face only. The study addressed three related questions: (1) Can a PVLS successfully be introduced into a course where IT has not previously featured? (2) Can the PVLSs be used to enhance the assessment from an extended essay to a higher-level empirical
Popular Abstract in Swedish Vår värld drivs av förbränning. Från den lilla elden som används vid matlagning till gigantiska gasturbiner och kolkraftverk som genererar en stor del av all elektricitet. Dessutom så drivs nästan alla fordon av förbränningsmotorer. Det har uppskattats att över nittio procent av alla energi vi i världen omvandlar kommer från förbränning i någon form. Det är således ganHigh repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. However, most laser systems in this field of research are limited to repetition rates below 100 Hz, and are thus
Abstract in UndeterminedThis article discusses the staff’s view on dementia and its impact on the care delivered arising outof a qualitative comparative study focusing on long-term care of older people in France, Portugaland Sweden. The aim was to explore the staff’s view on the illness dementia; on older peoplesuffering from dementia; the care provided and the impact of various views on the care.
Information about forest background reflectance is needed for accurate biophysical parameter retrieval from forest canopies (overstory) with remote sensing. Separating under- and overstory signals would enable more accurate modeling of forest carbon and energy fluxes. We retrieved values of the normalized difference vegetation index (NDVI) of the forest understory with the multi-angular Moderate R
Background: The aim was to compare findings related to experiences of prosthetics and orthotic service delivery in Tanzania, Malawi, Sierra Leone and Pakistan, from the perspective of local professionals.Method: In total 49 prosthetists/orthotists and prosthetic/orthotic technicians participated from four countries. A comparative analysis of the results of the three published papers was conducted.
BACKGROUND: Insomnia is a global problem and an important risk factor for patients living with cardiovascular disease (CVD), causing poor well-being and worsening disease prognosis. Yet, there is a lack of effective intervention strategies targeting sleep problems. To deliver patient-centered interventions and achieve good quality of sleep for this group, the own experiences of patients with CVD n
Crisis preparedness planning work can be characterized as complex and challenging being performed in large public organizations requiring communication and cooperation with many people. This paper reports on a bottom-up study investigating the pre-requisites for efficient crisis preparedness work, as well as motivational factors for implementing crisis preparedness decisions, which might be studie
This open, multinational, randomised, parallel-group, six-month extension conducted in the Swedish centres of a previous six-month study compared the costs of a total of 12 months of treatment with budesonide/formoterol in a single inhaler with budesonide plus formoterol separate inhalers in 320 adults with asthma. Patients received budesonide/formoterol (Symbicort® Turbuhaler®) 160/4.5 mg deliver
Objective: Studies have related air pollution to myocardial infarction (MI) events over days or weeks, with few data on very short-term risks. We studied risk of ST-segment elevation MI (STEMI) within hours of exposure to air pollution while adjusting for weather. Methods: We performed a case-crossover study of STEMI cases in Stockholm, Sweden (Jan 2000–June 2014) based on SWEDEHEART. Exposures du
We present a novel analysis of time-resolved extended x-ray absorption fine structure (EXAFS) spectra based on the fitting of the experimental transients obtained from optical pump/x-ray probe experiments. We apply it to the analysis of picosecond EXAFS data on aqueous [FeII (bpy)3] 2+, which undergoes a light induced conversion from its low-spin (LS) ground state to the short-lived (τ≈650 ps) exc
The aim of the MIRACHL project is the characterisation and monitoring of in-situ remediation of chlorinated hydrocarbon contamination using an interdisciplinary approach and geophysical methods, such as DCIP (direct current induced polarisation) to investigate the remediation process. To interpret these geophysical field IP data, lab investigations with different kinds of bacteria are necessary to
Over the last two decades, alternative and holistic concepts, such as Nature-based Solutions (NbS) were introduced and adopted by policy-makers, including to the field of flood protection, thereby causing a paradigm shift towards flood risk management. The inclusion of natural water retention measures (NWRM) such as dike relocation and floodplain restoration into the German guidelines for flood pr
