A quantitative study of copper (Cu) content in 19 different beer brands produced in mainly European countries and consumed in Sweden were measured using atomic absorption spectrophotometer without sample digestion. Results showed that the Cu content in beers is below the permissible levels concentrations for potable drinking water recommended by World Health Organization. In addition, the studies
Polysaccharides constitute one of the major groups of biological macromolecules and they include some of the most abundant macromolecules in nature. In this chapter instrumental considerations when analyzing polysaccharides with flow field-flow fractionation (flow FFF) are briefly discussed. Furthermore, an overview of characterized properties is given with special attention to multi angle light s
The 1990s and 2000s have seen a rapidly growing use of flow field-flow fractionation (flow FFF, FlFFF). As of today hundreds of publications in many different application areas are presented each year in which flow FFF has been used or is referred to. In this chapter a brief historical overview of flow FFF is given. Channel designs and basic principles are discussed as well as approaches to develo
Egg yolk is composed of large amounts of surface active components, such as different protein species and phospholipids. These surface active components can form an interfacial film between anoil phase and a water phase and thereby stabilize an emulsion. Egg yolk is therefore used in many foodemulsions, such as mayonnaise and dressings. Some authors have proposed that the low-density lipoprotein,
Since the most recent edition of the SHRA only stretches to 2000/2010, the main purpose of thecurrent edition has been to update the accounts using more recent data from Statistics Sweden(SCB) and the Swedish Historical National Accounts (SHNA) database. As the SHRA estimates build largely on the SHNA estimates, such a forward extension is now possible due to the recent and associated update of th
Since the most recent edition of the SHNA only stretches as far as 2010, the main purpose of the current edition has been to update the accounts using more recent data from Statistics Sweden (SCB). However, little attention has been paid in previous publications to precisely how this should be done. While it is noted that most of the accounts use data from Statistics Sweden from various points dur
The Russian war of aggression against Ukraine caused an escape of >7 million people to other European countries. In this extreme context, the accommodation of refugees has been an urgent need and an unexpected challenge for the host cities and societies. This short paper discusses insights and learnings on housing and accommodation of Ukraine war refugees at the local scale. It summarises challeng
In this paper, a novel three-dimensional (3D) irregularshaped geometry-based stochastic model (IS-GBSM) is proposedfor sixth-generation (6G) millimeter wave (mmWave) massivemultiple-input multiple-output (MIMO) vehicle-to-vehicle(V2V) channels. To investigate the impact of vehicular trafficdensity (VTD) on channel statistics, clusters are divided into staticclusters and dynamic clusters, which are
Carefully selecting the right collection datastructure can significantly improve the performance of a Java program. Unfortunately, the performance impact of a certain collection selection can be hard to estimate.To assist developers there are tools that recommend collections to use based on static and/or dynamic information about a program. The majority of existing collection selection tools for J
Statistics are part of any empirical science, and performance analysis is no exception. However, for non-statisticians, picking the right statistical tool to answer a research question can be challenging; each statistical tool comes with a set of assumptions, and it is not clear to researchers what happens when those assumptions are violated. Bayesian statistics offers a framework with more flexib
It is shown that the behavior of an m-port circuit of maximal monotone elements can be expressed as a zero of the sum of a maximal monotone operator containing the circuit elements, and a structured skew-symmetric linear operator representing the interconnection structure, together with a linear output transformation. The Condat–Vũ algorithm solves inclusion problems of this form, and may be used
Background: In education, lecturers play a crucial role in facilitating students’ learning process. However, only a few studies explored which lecturers’ characteristics can facilitate this process in higher education for rehabilitation healthcare professionals. Starting from students’ perspectives, our qualitative study investigated the lecturers’ characteristics that facilitate students’ learnin
Lower limbs position sense is a complex yet poorly understood mechanism, influenced by many factors. Hence, we investigated the position sense of lower limbs through feet orientation with the use of Immersive Virtual Reality (IVR). Participants had to indicate how they perceived the real orientation of their feet by orientating a virtual representation of the feet that was shown in an IVR scenario
