The purpose of this study is to investigate the computational time required to describe the fluid flow behavior through a porous medium and its relation to the corresponding domain size. The fluid flow behavior is recovered using the lattice Boltzmann method (LBM). The selected methodology has been applied because of its feasibility for mimicking the fluid flow behavior in complex geometries and m
Purpose: The 4-kallikrein panel, commercially available as the 4Kscore™, is a reflex test for prostate cancer early detection that has been extensively validated in multiple international cohorts. It has been suggested that use of such reflex tests be limited to those with prostate specific antigen less than 10 ng/ml and negative digital rectal examination. We aimed to determine the value of the p
We present a vertical nanowire InAs/GaAsSb/GaSb TFET with a highly scaled InAs diameter (20 nm). The device exhibits a minimum subthreshold swing of 48 mV/dec. for Vds = 0.1-0.5 V and achieves an Ion = 10.6 μA/μm for Ioff = 1 nA/μm at Vds = 0.3 V. The lowest subthreshold swing achieved is 44 mV/dec. at Vds= 0.05 V. Furthermore, a benchmarking is performed against state-of-the-art TFETs and MOSFETs
BACKGROUND: The effect of a treatment that includes frequent changes of the body position for infants with bronchiolitis has not been evaluated, although it is often used in Swedish hospitals. Because of this, a randomised control trial (RCT) has begun with the aim to evaluate this treatment, comparing the effect of an individualised physiotherapy intervention, a non-individualised intervention, a
OBJECTIVE: We have compared the effectiveness, time required for de-airing, and safety of a newly developed de-airing technique for open left heart surgery (Lund technique) with a standardized carbon dioxide insufflation technique. METHODS: Twenty patients undergoing elective open aortic valve surgery were randomized prospectively to the Lund technique (Lund group, n = 10) or the carbon dioxide in
There are increasing reports of deaths and serious complications associated with the use of negative pressure wound therapy (NPWT). Bleeding may occur in patients when NPWT is applied to a wound with exposed blood vessels or vascular grafts, possibly due to mechanical deformation and hypoperfusion of the vessel walls. Recent evidence suggests that using a rigid barrier disc to protect underlying t
Popular Abstract in Swedish De flesta av Sveriges cirka 15000 större broar är byggda i betong. Ett problem som kan uppkomma i betongbroar är sprickor, vilka kan bidra till att minska broarnas beständighet och säkerhet. I en del broar har fler sprickor uppkommit på sydsidan än på nordsidan vilket antyder att solen har stor påverkan på dessa broar, eftersom det är den enda faktor som skiljer sig väsWhen the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. If the movements are prevented, stresses may be induced which can contribute to cracks in the structure. Severe cracks have be
We present an update of a search for supersymmetry in final states containing jets, missing transverse momentum, and one isolated electron or muon, using 1.04 fb(-1) of proton-proton collision data at root s =7 TeV recorded by the ATLAS experiment at the LHC in the first half of 2011. The analysis is carried out in four distinct signal regions with either three or four jets and variations on the (
Objective: The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent' and 'constant' pain. Theses are conceptually different from 'pain on activity' and pain 'intensity' as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and diffe
A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb−1 of s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel search techniques based on continuous wavelet transforms are used to infer the frequency of periodic signals from the invariant mass spectra and neural network c
Aim: To evaluate the incidence of chromosomal aberrations in apparently isolated ventricular septal defects (VSD), quantify the timing of diagnosis of prenatally diagnosed VSDs, and define the spontaneous closure rate prenatally both in utero and during the first year of life. Materials and methods: Medline, PubMed, and the Cochrane Database Library were searched to identify studies published betw
Popular AbstractSyftet med avhandlingen är att undersöka på vilket sätt teater med ungdomar, enligt ungdomarnas egna erfarenheter och utsagor om det, utgör en kollektiv bildningsprocess. I avhandlingens syfte ingår att analysera hur en teaterföreställning växer fram och att skapa förståelse för vad som sker mellan olika aktörer, främst mellan ungdomar och ledare.Forskningsfenomenet, unga människorThe objective of this research project is to investigate in what way young people's theatre playing, according to their own experiences, constitute a collective educational process. Also, the project aims at understanding the interaction between the different actors, and particularly between the young amateurs and their leaders. Young people's acting in this research project is understood from a p
Professionals who take part in the building process have long been concerned with the same environmental factors, e.g. spatial layout, capacity, and function, as well as user demography. Through the knowledge gained on the ways environmental factors affect users of buildings, the need to understand how to handle these factors has grown, due to their influence on the building process. It will be sh
When a child has special communication needs, his or her entire family is affected. This position paper deals with “Xings” (crossings or just xings): active and reactive multisensory media, designed to be communicative on their own terms, challenging existing everyday communication patterns and augmenting family communication. The common shortcomings of oral and written language are no longer crit
New robot applications increasingly require external sensing to accomplish robustness and performance despite the variations and uncertainties that come with the increasing demands on flexibility for manufacturing of customized products. The demands on productivity then require high performance, which for well known feedback-control reasons means short response times from external process event to
The adsorption and surfactant induced removal of T4 lysozyme was studied by in situ ellipsometry. Two proteins were investigated, wild type T4 lysozyme and a mutant protein where isoleucine 3 had been replaced by tryptophan (tryptophan mutant). The amount adsorbed is higher for the wild type protein than for the tryptophan mutant at the protein concentration employed (0.2 mg/mL). Furthermore, the
