Continuous acoustic sorting of E. Coli and G. Lamblia in drinking water

This paper presents an acoustofluidic chip for the sorting of bacteria from protozoa in water using standing acoustic waves. The size-based acoustophoretic sorting method provides a means for sample pre-concentration, which is vital for real-time, on-site monitoring of drinking water quality and preventing outbreak of waterborne diseases. In practice, high throughput and high recovery pre-concentr

Cost Analysis of a Digital Health Care Model in Sweden

Digital technologies in health care areexpected to increase in scope and to affect ever more partsof the health care system. It is important to enhance theknowledge of whether new digital methods and innovationsprovide value for money compared with traditional modelsof care.Objective The objective of the study was to evaluatewhether a digital health care model for primary care is aless costly alte

RapidHIT for the purpose of stain analyses - An interrupted implementation

Rapid DNA instruments have in recent years been developed, enabling analysis of forensic samples with a minimum of human intervention. Initially intended for fast handling of reference samples, such as samples from suspects in booking suites, attention shifted to include crime scene samples. The aim of this study was to determine whether or not the RapidHIT System (IntegenX) is fit for crime scene

Acoustic trapping efficiency of nanoparticles and bacteria

In this paper we present a method to characterize the acoustic trapping efficiency of nanoparticles and bacteria when using seeding particles. Through the use of fluorescent microscopy and video analysis, single particles/bacteria were counted as they entered the acoustic trap at different flow focusing ratios and by comparing the amount of trapped objects to the amount of objects that were lost f

Correlation of precipitate evolution with Vickers hardness in Haynes® 282® superalloy : In-situ high-energy SAXS/WAXS investigation

The aim of this work is to characterize the precipitation kinetics in Haynes® 282® superalloys using in-situ high-energy Small Angle X-ray Scattering (SAXS) together with Wide Angle X-ray Scattering (WAXS). The phases identified by WAXS include γ (matrix), γ′ (hardening precipitates), MC (metallic carbides), and M23C6/M6C (secondary metallic carbides). The γ’-precipitates are spheroids with a diam

BasisFunctionExpansions.jl : Basis Function Expansions for Julia

A Julia toolbox for approximation of functions using basis function expansions (BFEs).BFEs are useful when one wants to estimate an arbitrary/unknown/complicated functional relationship between (in the simple case) two variables, y and v. In simple linear regression, we might consider a functional relationship y = ϕ(v) = αv + β, with parameters α and β. However, if the function ϕ has an arbitrary

Attosecond transient absorption of a bound wave packet coupled to a smooth continuum

We investigate the possibility of using transient absorption of a coherent bound electron wave packet in hydrogen as an attosecond pulse characterization technique. In a recent work, we have shown that photoionization of such a coherent bound electron wave packet opens up for pulse characterization with unprecedented temporal accuracy - independent of the atomic structure - with maximal photoemiss

Is Competitive Elite Sport Really Morally Corrupt?

It has been argued that competitive elite sport both a) reduces the humanity of athletes by turning them into beings whose sole value is determined in relation to others, and b) is motivated by a celebration of the genetically superior and humiliation of the weak. This paper argues that while a) is a morally reproachable attitude to competition, it is not what competitive elite sport revolves arou

Composition and sources of carbonaceous aerosols in Northern Europe during winter

Sources of elemental carbon (EC) and organic carbon (OC) in atmospheric aerosols (carbonaceous aerosols) were investigated by collection of weekly aerosol filter samples at six background sites in Northern Europe (Birkenes, Norway; Vavihill, Sweden; Risoe, Denmark; Cabauw and Rotterdam in The Netherlands; Melpitz, Germany) during winter 2013. Analysis of 14C and a set of molecular tracers were use

Diode laser-based thermometry using two-line atomic fluorescence of indium and gallium

A robust and relatively compact calibration-free thermometric technique using diode lasers two-line atomic fluorescence (TLAF) for reactive flows at atmospheric pressures is investigated. TLAF temperature measurements were conducted using indium and, for the first time, gallium atoms as temperature markers. The temperature was measured in a multi-jet burner running methane/air flames providing var

A two-level directional model for dependence in circular data

We present a likelihood-based test for clustering among sub-population mean directions for circular data. The test is based on a two-level hierarchical model with von Mises distributed variation on each level. The properties of the tests are investigated and compared to the commonly applied techniques of second-order analysis and pseudo-pooling of directions for the situation at hand. Finally we a

Predictors of Liver Fat and Stiffness in Non-Alcoholic Fatty Liver Disease (NAFLD) - An 11-Year Prospective Study

Liver fat can be non-invasively measured by proton magnetic resonance spectroscopy (1H-MRS) and fibrosis estimated as stiffness using transient elastography (FibroScan). There are no longitudinal data on changes in liver fat in Europids or on predictors of liver stiffness using these methods. We determined liver fat (1H-MRS) and clinical characteristics including features of insulin resistance at
