1. IntroductionThe demand for efficient oil-water separation is driven by the tightening of discharge limits for e.g. produced water in the oil and gas industry, process water in the petrochemical industry and bilge water in the marine industry. The global produced water production alone is over 71 billion bbl/a – 8.4 billion m3/a [1]. Among the different technologies, particularly ultrafiltration
Is there a variation in facial ideals depending on ethnic background that affects judgements of outcome in orthognathic surgery? How does the evaluation correlate with patient-reported outcome measures? Two evaluation panels, Singaporean and Swedish, judged photographs of patients undergoing orthognathic surgery taken before and after operation. Improvement in facial aesthetics was calculated betw
Dams, weirs, and hydropower facilities are often cited as migratory barriers which impart significant reductions in fitness among migratory fish species. Even where upstream and downstream passage options are available, barrier passage can still often result in energetic or physical costs which compound delays or cause mortality. Past studies have identified variables associated with such fitness
Background: The use of chat-based digital visits (eVisits) to assess infectious symptoms in primary care is rapidly increasing. The "digi-physical" model of care uses eVisits as the first line of assessment while assuming a certain proportion of patients will inevitably need to be further assessed through urgent physical examination within 48 h. It is unclear to what extent this approach can mitig
I denna studie görs en uppdaterad analys av den länsvisa tillgången på skogsbaserade rest- och biprodukter i form av grenar och toppas (grot) vid föryngringsavverkningar, bark från sågverk och massabruk, sågspån (och kutterspån) från sågverk samt lignin från svartlut i sulfatmassabruk som råvara för framtida produktion av biodrivmedel/bioflygbränsle. Analysen inkluderar också beräkningar av teoretThis study includes an updated analysis of the regional potential of forest-based residues and by-products in form of logging residues after final felling’s, bark in sawmills and pulp mills, sawdust in sawmills, and lignin from black liquor in pulp mills, as feedstocks for future production of biofuels and biojet fuels. The analysis also include calculations of theoretical transportation distances
Objective: To determine the serotype distribution and antimicrobial resistance of Streptococcus pneumoniae associated with mucosal infections in patients of all ages, 2 to 4 years after the transition from a 10-valent pneumococcal conjugate vaccine (PCV10) to PCV13 in the childhood immunization programme. Methods: Background information and antimicrobial susceptibility data regarding all respirato
A general framework for the formulation and analysis of an overall decision support index is discussed. It is indicated that such an index allow evaluation of the combined effects of both design and operation (i) during the planning phase of new WWTPs, as well as (ii) for the evaluation of new operational strategies versus traditional expansions of plants already in operation. Attention is drawn t
BACKGROUND: In order to determine myocardial salvage, accurate quantification of myocardium at risk (MaR) is necessary. We present a validated novel automatic segmentation algorithm for quantification of MaR by myocardial perfusion SPECT (MPS) in patients with acute coronary occlusion. METHODS AND RESULTS: Twenty-nine patients with coronary occlusion were injected with a perfusion tracer before re
When it goes into operation in 2016, the MAX IV 3 GeV storage ring will be the first ultralow-emittance storage ring based on a multibend achromat lattice. Such ultralow-emittance rings make use of a large number of weak bending magnets which leads to low radiation losses in the dipoles compared to power radiated from insertion devices. Therefore, the emittance in such rings depends strongly on th
BACKGROUND: Liver resection is a possibly curative treatment for colorectal cancer (CRC) liver metastases. Preoperative chemotherapy may make initially irresectable tumors resectable. The aim of this study was to compare perioperative course and short-term mortality after liver resection for CRC metastases between patients who were and were not treated with preoperative chemotherapy. METHODS: Pati
Type 2 diabetic patients often die because of end-stage renal failure, but no definitive reliable factor predicting long-term renal outcome has been identified. We tested whether a renal arterial resistance index (R/I) >= 80, using Doppler ultrasound technique, was predictive of worsening renal function. The primary end points of the study were 1) the course of glomerular filtration rate (GFR) and
The kinetics of sorption of water vapor in mature cement mortar are examined experimentally by the use of a sorption balance (DVS1000). The relative humidity in the sample chamber is obtained by mixing dry and saturated air using flow regulators with very high accuracy. A predefined change of relative humidity in the sample chamber can be obtained in about 30 s. The time needed for equilibration i
The membrane lipid glucosylceramide (GlcCer) is continuously formed and degraded. Cells express two GlcCer-degrading β-glucosidases, GBA and GBA2, located in and outside the lysosome, respectively. Here we demonstrate that through transglucosylation both GBA and GBA2 are able to catalyze in vitro the transfer of glucosyl-moieties from GlcCer to cholesterol, and vice versa. Furthermore, the natural
OBJECTIVE: The aim of this study was to investigate the effect of epidermal growth factor receptor (EGFR) blockade on cell survival and on downstream signalling pathways using the monoclonal antibody cetuximab. METHODS: We used three colon cancer cell lines, of which one was EGFR-negative, and two head and neck squamous cell carcinoma (HNSCC) lines. EGFR expression and gene copy number were measur
The double quantum coherence (DQC) signal in nonlinear spectroscopy gives information about the many-body correlation effects not easily available by other methods. The signal is short-lived, consequently, a significant part of it is generated during the pulse overlap. Since the signal is at two times the laser frequency, one may intuitively expect that the pulse overlap-related artifacts are filt
Polymer electrolyte fuel cell (PEFC) development goes hand in hand with a complete understanding of its behavior in realistic operating conditions. Hence, analysis based on characterizations is essential to determine the predominant effects strongly affecting PEFC performance. Experimental research is carried out using a single PEFC under controlled conditions. The primary objective is to examine
This study investigates the relationship between changes in the frequency of dwell time delays and passenger flow characteristics and the frequency of railway service during the COVID-19 pandemic. To do so we make use of automatic passenger count data from commuter trains in Southern Sweden. Our findings show that the frequency of dwell time delays decreased under COVID-19 conditions compared to t
Background: Whole-body skeletal radiography has traditionally been used in the management of multiple myeloma for defining treatment strategies. For several reasons, radiography has been replaced by computed tomography (CT) covering the same regions. Purpose: To evaluate the body mass index (BMI) adjusted effective radiation dose from two different methods of whole-body radiologic imaging for mult
The interfacial nanostructure of the three most widely-studied Deep Eutectic Solvents (DESs), choline chloride:urea (ChCl:Urea), choline chloride:ethylene glycol (ChCl:EG), and choline chloride:glycerol (ChCl:Gly) at a Pt(111) electrode has been studied as a function of applied potential and water content up to 50 wt%. Contact mode atomic force microscope (AFM) force-distance curves reveal that fo
Background. Neisseria meningitidis (Nm) is a Gram negative diplococcus causing bacterial meningitis and fulminant septicemia. In order to allow efficient characterization of infecting strains, antibody reagents for use as analytical tools have proven to be invaluable tools. Similarly, antibodies against relevant bacterial antigens may guide in the selection of components to be included in developi
