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

The transmission of vibrations over the surface of the ground, due to a high-speed moving, vertical harmonic strip load, is investigated theoretically. Consequently, the problem is essentially two-dimensional and the interior of the ground is modelled as an elastic half-space. The transformed solutions are obtained using the Fourier transform on the space variable. A study of a new damping model i

A boundary integral equation is described for the prediction of acoustic propagation from a monofrequency coherent line source in a cutting with impedance boundary conditions onto surrounding flat impedance ground. The problem is stated as a boundary value problem for the Helmholtz equation and is subsequently reformulated as a system of boundary integral equations via Green's theorem. It is shown

The transmission of vibrations, and its reduction, in the far-field of the surface of the ground due to a harmonic load acting over a strip, is investigated theoretically. A possible vibration attenuation device that has shown some promise is the "wave impedance block" (WIB). The principle of this is to modify the modal wave propagation regime of the ground by introducing an artificial stiffened l

The transmission of vibrations over the surface of the ground, due to a moving, vertical harmonic rectangular load, is investigated theoretically. The interior of the ground is modelled as an elastic half-space. The transformed solutions are obtained using the double Fourier transform. Numerical results for the displacements on the surface are presented for loads moving with speeds up to the Rayle

What does a postcolonial ethics of care mean for feminist geographers doing archival work? Feminist geographers have long called for ethical research engagement. This asserts the importance of caring relationships with research mentees, collaborators, participants, and spaces. But care comes both with promise and pitfalls. As postcolonial and antiracist geographers argue, we must emplace care. Tha

This book delineates the scope of permissible compulsory mental health interventions under the Convention on the Rights of Persons with Disabilities (CRPD).The initial impetus for this study was provided by a conflict between two competing positions within the current debate over the future of coercive psychiatry. According to one position, defended by the CRPD Committee, among others, compulsory

People who spread misinformation in public debates expose others to the risk of forming false beliefs. Excluding them from participation can limit this exposure, but fact-checking takes up resources of time and money, and censorship violates social and political norms. Here, computer simulations of Bayesian learning in social networks suggest that, in some contexts anyway, the epistemic benefits o

This paper draws on two ethnographic research projects in Japanese university sports clubs to examine the role alcohol plays in the social and cultural education of students. Over the course of a four-year membership, the university sports club is a site where members learn to negotiate drinking. This negotiation is demonstrated by the range of strategies members employ when engaging in one of the

Background: Thrombocytopenia is correlated to hemorrhagic complications in patients with low molecular weight heparin (LMWH) thromboprophylaxis. Aims: The aims of our study were to investigate an experimentally induced in vitro thrombocytopenia and then adding 2 types of LMWHs in vitro. Our hypothesis was that a platelet depleted whole blood sample could reflect a stronger synergistic anticoagulat

Research that engages with the intersection of sport and gender needs to consider aspects of social interaction not only of the physical component of the sport but also the other day-to-day activities related to it. The examination of women and kendo-related hegemonic drinking in this chapter provides an insightful perspective and highlights the value of the ethnographic method in unexplored place

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

The cost of renewable energy from wind and solar in 2019 plunged to the low levels that few policy-makers anticipated only several years ago. Such technological developments have broad implications for all Central Asian economies. The share of wind and solar energy in the region remained negligible for a long time due to the abundant supply of cheap energy from fossil or hydro resources. Central A

BakgrundFör att tackla den rådande SARS-COV-2-pandemin har det ställts höga krav på en snabb utveckling och utvärdering av nya antivirala läkemedel. Bland några av de antivirala läkemedelskandidaterna finns imiquimod, en TLR7 agonist normalt administrerad för behandling av könsvårtor och basalcellscarcinom. Eftersom det har påvisats att imiquimod kan öka den antivirala responsen, är vår hypotes at
