As an effective strategy to control the combustion of advanced combustion modes, the application of variable valve timing (VVT) in reactivity controlled compression ignition (RCCI) combustion was investigated in this study. By coupling KIVA-3V code with genetic algorithm, the combustion of a heavy-duty engine with RCCI combustion combined with VVT strategy was optimized under a wide load range. At
A systematic assessment of radiotherapy for cancer was conducted by The Swedish Council on Technology Assessment in Health Care (SBU) and published in 1996. The assessment reviewed the scientific literature up to 1993 on the use of radiotherapy in the treatment of solid tumours. and estimated the costs associated with radiotherapy It also described the current practise of radiotherapy in Sweden 19
The relationship among CCR5 genotype, cytomegalovirus infection, and disease progression and death was studied among 159 human immunodeficiency virus (HIV)-infected patients with hemophilia. One patient (0.6%) had the CCR5Delta32/CCR5Delta32 genotype (which occurs in similar to2% of the Scandinavian population) and a rapid disease course. His HIV V3 region contained genotypic features attributable
The effect of a study day on the subject of pain for nurses working at the thorax surgery department The aims of this investigation were: to describe patients' evaluation of pain and the treatment of pain after thorax surgery via sternotomy; to repeat the evaluation with another group of patients following a study day for nurses, featuring pain and pain treatment; and to examine whether the study
It is established that the glomerular filter sieves macromolecules based on their size, shape, and charge. Anionic proteins are thus retarded compared with their neutral or cationic counterparts. However, recent studies have indicated that charge effects are small, or even "anomalous," for polysaccharides. We therefore investigated the impact of charge on the glomerular permeability to polysacchar
Background and Aims: Incisional hernia development is a frequent long-term sequel after open abdomen treatment. This report describes a novel technique, the vacuum-assisted wound closure and permanent onlay mesh–mediated fascial traction for temporary and final closure of the open abdomen, with the intention to decrease incisional hernia rates. Primary aim was to evaluate incisional hernia develop
Cosmological models and their parameters are widely debated, especially about whether the current discrepancy between the values of the Hubble constant, H 0, obtained by Type Ia supernovae (SNe Ia) and the Planck data from the cosmic microwave background radiation could be alleviated when alternative cosmological models are considered. Thus, combining high-redshift probes, such as gamma-ray bursts
Background: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volu
STUDY QUESTION Does an intensive weight reduction programme prior to IVF increase live birth rates for infertile obese women? SUMMARY ANSWER An intensive weight reduction programme resulted in a large weight loss but did not substantially affect live birth rates in obese women scheduled for IVF. WHAT IS ALREADY KNOWN Among obese women, fertility and obstetric outcomes are influenced negatively wit
Background: Many existing patient-reported outcome measures are extensive regarding both patient burden and administration, and in terms of analysing and reporting results. The VascuQoL-6 (VQ6) - a short version of the original Vascular Quality of Life Questionnaire (VascuQoL), a disease-specific instrument for peripheral arterial disease - was recently developed. However, the VQ6 has not yet been
Background: A panel of four kallikrein markers (total, free, and intact prostate-specific antigen [PSA] and human kallikrein-related peptidase 2 [hK2]) improves predictive accuracy for Gleason score ≥7 (high-grade) prostate cancer among men biopsied for elevated PSA. A four-kallikrein panel model was originally developed and validated by the Dutch center of the European Randomized Study of Screeni
A search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq¯(′)bb¯ final state is described. The search uses 36.1 fb−1 of proton–proton collision data at s=13 TeV collected by the ATLAS detector at the CERN Large Hadron Collider in 2015 and 2016. The data are in agreement with the Standard Model expectations, with the largest excess found at a resonance mass of 3.0 TeV wit
The study describes extraction of extracellular polymeric substances (EPS) from sewage sludge by applying enzymes and enzymes combined with sodium tripolyphosphate (STPP). Additionally, a systematic study of two non-enzymatic extraction agents is described. The assessment of the released products is made by colorimetrical methods and polysaccharides/glycoconjugates identification by the interactio
Blood coagulation factor IX is composed of discrete domains with an NH2-terminal vitamin K-dependent gamma-carboxyglutamic acid (Gla)-containing region, followed by two domains that are homologous with the epidermal growth factor (EGF) precursor and a COOH-terminal serine protease part. Calcium ions bind to the Gla-containing region and to the NH2-terminal EGF-like domain. To be able to determine
OBJECTIVES: To investigate the experiences of a digital management programme for hip and knee osteoarthritis (OA), including education and exercises as well as an option to chat with an assigned physical therapist for feedback, questions and support.SETTING: This study was conducted at a regional hospital in the southern part of Sweden.METHODS: Nineteen patients (10 women), median age of 66 (q1-q3
Unsafe abortion is a major contributing factor to maternal mortality with 47,000 largely avoidable deaths occurring globally every year, the majority in the global south. Ethiopia has taken a unique approach to addressing maternal mortality impacted by unsafe abortion through a 2005 reform of the abortion legislation in which abortion is illegal but available under a range of exceptions. The purpo
In this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE)
