We consider steady symmetric gravity water waves on finite depth with constant vorticity and a monotone surface profile between crests and troughs. The problem is transformed into one concerning the vertical velocity. A representation formula for the stream function in terms of the surface and the vorticity is presented, and we show that the surface can be determined from the vertical velocity.
Downscaling of microfluidic cell culture and detection devices for electrochemical monitoring has mostly focused on miniaturization of the microfluidic chips which are often designed for specific applications and therefore lack functional flexibility. We present a compact microfluidic cell culture and electrochemical analysis platform with in-built fluid handling and detection, enabling complete c
In this article an operator theoretic interpretation of the generalized Titchmarsh-Weyl coefficient for the Hydrogen atom differential expression is given. As a consequence we obtain a new expansion theorem in terms of singular generalized eigenfunctions.
Cancer-associated fibroblasts (CAF) stimulate tumor growth and metastasis. Signals supporting CAF function are thus emerging as candidate therapeutic targets in the tumor microenvironment. The chemokine CXCL14 is a potent inducer of CAF protumorigenic functions. This study is aimed at learning how the protumoral functions of CXCL14-expressing CAF are maintained. We found that the nitric oxide synt
We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that
This paper presents the 16-element antenna array with parasitic microstrip antenna single element. Antenna designed to operate at 60 GHz and its structure based on low-temperature cofired ceramic (LTCC) substrate. Gain more then 18 dBi and return loss bandwidth about 20% were obtained after antenna geometry parameters optimization
Background: Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigate
Background The Chemotaxis inhibitory protein of Staphylococcus aureus (CHIPS) blocks the Complement fragment C5a receptor (C5aR) and formylated peptide receptor (FPR) and is thereby a potent inhibitor of neutrophil chemotaxis and activation of inflammatory responses. The majority of the healthy human population has antibodies against CHIPS that have been shown to interfere with its function in vit
The European Spallation Source (ESS) linac will consist of three families of superconducting RE cavities to accelerate protons to a final beam energy of 2.5 GeV for collision with the target. Beam induced HOMs in these cavities may drive the beam unstable and increase the cryogenic load, severely limiting the operation of the linac. The effect of these modes on the beam quality is investigated in
This is the first of two papers introducing a novel thermomechanical continuum constitutive model for cemented granular materials. Here, we establish the theoretical foundations of the model, and highlight its novelties. At the limit of no cement, the model is fully consistent with the original Breakage Mechanics model. An essential ingredient of the model is the use of measurable and micro-mechan
The model for permanent deformation in asphalt concrete (AC) layers used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) was evaluated. Two instrumented flexible pavements were subjected to heavy vehicle simulator testing at three constant temperatures. Permanent deformation modelling was carried out using the MEPDG software v1.003 at the highest accuracy level. The nationally calibrate
Pickering emulsions are emulsions that are stabilized by fine particles. They have been the focus of considerable research in the past decade due to their properties such as high stability with respect to coalescence and Ostwald ripening, as well as due to advances in nanotechnology that allows us to create and characterize nano-scale structures in new ways. This work reviews some of the recent wo
The potential microbial risk from using treated wastewater is a burning issue to be studied. In Sweden, only a small part of treated wastewater is reused directly, although water reuse could be beneficial. Disinfection is virtually never practised and no protective guidelines for water reuse are found in Sweden. Based on a 1 year monitoring programme of water quality, this paper estimates the micr
There is a need for integrated care and smooth collaboration between care-providing organisations and professions to create a continuum of care for frail older people. However, collaboration between organisations and professions is often problematic. The aim of this study was to examine the process of implementing a new continuum of care model in a complex organisational context, and illuminate so
The purpose of this project was to investigate the possibilities to manufacture wet-glued laminated beams for load bearing applications from Norway spruce side board lamellae and by that achieve products that are difficult to obtain from the centre yield of a log and also contribute to increased profitability in the sawmill industry.
Properties such as shape stability, strength an
En enkätundersökning har genomförts bland brandingenjörer i Sverige med syftet att få information om detektionstider samt reaktions- och beslutstider vid en utrymning av tre olika lokaltyper; varuhus, restaurang och danslokal/nattklubb. Reslutaten kan ligga till grund för fortsatta studier för att bestämma partialkoefficienter för dimensionering av de gångvägar som används vid utrymning. Den ger o
Popular Abstract in Swedish Gasturbiner har länge varit en ekonimsk och driftsäkert sätt att producera energi. Främst har dom använts för framdrivning av flygplan och production av elektricitet och värme. Dom ständigt ökade kraven på miljöfarliga emissioner har tvingat fram nya metoder för att producera kraft. Nästa generations kraftverk måste ha hög termisk verkningsgrad samt mycket låga emissionGas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. The requirements for these new power cycles are substantially better emissions, hig
