The atmospheric profile whose sound speed varies linearly with height is simple in concept, but leads to complications when solving for the sound pressure. Its effects are commonly approximated by a similar profile whose squared refractive index is a linear function of height. In this paper, the validity of the approximation has been examined for sound propagation above an impedance ground and a c

A spectral element method is described which enables reduced wave equation problems defined in regular, arbitrary length regions to be solved as a set of coupled problems over neighbouring domains. A combination of trial functions are considered, namely the specific eigenfunctions of a differential operator and a set of hierarchical polynomials. Accurate approximations are obtained for computation

The transmission of vibrations over the surface of the ground, due to high-speed moving, vertical harmonic rectangular loads, is investigated theoretically. The problem is three-dimensional and the interior of the ground is modelled as an elastic half-space or a multilayered ground. The transformed solutions are obtained using the Fourier transform on the space variable. A new damping model in the

Introduction: Initiating low molecular weight heparin (LMWH) thromboprophylaxis too early in patients with traumatic braininjury increases the risk of intracranial bleeding. Therefore, it is important to monitor LMWH and asses when it is safe to initiate.The aim of this research was to study alternative monitoring methods for LMWH than the standard method anti-factor Xa (antiFXa), and to investiga

Luminescent centers in the two-dimensional material hexagonal boron nitride have the potential to enable quantum applications at room temperature. To be used for applications, it is crucial to generate these centers in a controlled manner and to identify their microscopic nature. Here, we present a method inspired by irradiation engineering with oxygen atoms. We systematically explore the influenc

Performance appraisal reports provide vital information for making strategic decisions. Uniting HR practices and IT is an attempt to maximize value creation. Organizations are transforming their performance management systems from traditional to web‐technology based systems to enhance accuracy and objectivity. The present study is an effort to assess employees’ perception of the accuracy of e‐perf

Measurements of the Standard Model Higgs boson decaying into a bb¯ pair and produced in association with a W or Z boson decaying into leptons, using proton–proton collision data collected between 2015 and 2018 by the ATLAS detector, are presented. The measurements use collisions produced by the Large Hadron Collider at a centre-of-mass energy of s=13Te, corresponding to an integrated luminosity of

The article analyses a case of prosecution for human smuggling. Three film crew members accompanied a Syrian refugee boy from Greece to Sweden, while recording the journey in a documentary that was screened on Swedish public television in 2015. Despite widespread recognition, they were prosecuted and found guilty of human smuggling by all the levels of the Swedish judiciary. Using a variety of mat

Background: In the field of movement disorders, what you see (phenotype) is seldom what you get (genotype). Whereas 1 phenotype was previously associated to 1 gene, the advent of next-generation sequencing (NGS) has facilitated an exponential increase in disease-causing genes and genotype-phenotype correlations, and the "one-phenotype-many-genes" paradigm has become prominent.Objectives: To highli

This chapter presents a socio-historical perspective on the origin and development of the Swedish school field and the teaching professions. With Bourdieu as a source of inspiration, the school field is defined as a system of specialized institutions and agents (church, state, academy, teachers’ unions) who, based on different interests and positions, compete for recognition and power to define th

The current research studied effects of different gender expressions (non-normative or normative)in two phases of recruitment: applicant attraction and applicant evaluation. Experiment 1 (N = 404) investigated how Equal Employment Opportunity (EEO) statements in an organisation description that emphasized gender as binary (women and men), gender as diverse (multi-gender), or gender as irrelevant (

This article examines the role of policy entrepreneurs in promoting change in flood risk mitigation at the local level in Sweden through a comparative study of two Swedish municipalities with different approaches to flood risk governance; as a technical issue or a social issue. The municipality in which flood risk mitigation is addressed as a social issue exhibits a larger size of the network miti

The type and relative position of evacuation signage to evacuees’ location can affect their likelihood to understand and comply with the information provided. To address this issue, a Virtual reality (VR) experiment with 60 participants was carried out to investigate the effect of signage vs viewer placement on the compliance with the indicated direction in case of evacuation. The VR experiments w

Nonspecific structural chromosomal aberrations (CAs) can be found at around 1% of circulating lymphocytes from healthy individuals but the frequency may be higher after exposure to carcinogenic chemicals or radiation. The frequency of CAs has been measured in occupational monitoring and an increased frequency of CAs has also been associated with cancer risk. Alterations in DNA damage repair and te
