The normally functioning heart delivers a steady supply of oxygen and nutrients to the body over a broad range of physiological states and loading conditions. Efficient cardiac performance at rest and during exercise is therefore a primary evolutionary directive for survival. The four-chambered heart is primarily a volume pump. It couples systolic and diastolic properties because of simultaneous r
The paper presents new geological, geochronological, geochemical, and Nd isotopic data on the late Paleoproterozoic dolerites of the Siberian craton. U-Pb baddeleyite ages of the Doros dolerites (Aldan shield, south-eastern Siberia) and East Anabar dolerites (Anabar shield, northern Siberia) are 1757 ± 4 and 1774 ± 6 Ma, respectively. This new geochronological data together with published 1.76–1.7
One of the key implications of COVID-19 is the adoption of physical distancing provisions to minimise the risk of virus transmission. Physical distancing can have significant consequences on crowd movement both in normal conditions and during emergencies. The impact of physical distancing is discussed in this chapter by first presenting an overview of its implications on crowd dynamics and space u
Standing wave ambient pressure photoemission spectroscopy (SWAPPS) is a promising method to investigate chemical and potential gradients across solid-vapor and solid-liquid interfaces under close-to-realistic environmental conditions, far away from high vacuum. Until now, these investigations have been performed only near room temperature, but for a wide range of interfacial processes, chief among
Analytical solutions for a one-line model for shoreline changes are employed to investigate the formation of two wave-dominated river delta coastlines, along with a small-scale laboratory experiment. Since the present analytical solution can be applied only to a river delta with infinite shorelines, a new analytical solution was developed to consider the effects of lateral boundaries to the evolut
Disability is frequently cited as a reason that Americans do not vote. This article offers legal and policy practitioner perspectives on core challenges people with disabilities face in exercising their voting rights in the United States, from obtaining election information to casting their ballots. Drawing on our collective experience-which includes professional experience as advocates working to
After its inauguration in 2000, the Oresund bridge has allowed major mobility and flow of manpower, goods, and services between Sweden and Denmark. Was this the vision that Danes and Swedes have imagined over the past century and a half, when thinking of a bridge over the Sound? And, if so, why did it take more than one hundred years in order to start the construction of the øresundsförbindelsen?
Atomically thin semiconductors are one of the fastest growing categories in materials science due to their promise to enable high-performance electronic and optical devices. Furthermore, a host of intriguing phenomena have been reported to occur when a semiconductor is confined within two dimensions. However, the synthesis of large area atomically thin materials remains as a significant technologi
Although students' understanding of the concept of function has been studied by quite a number of researchers internationally, there has not been a lot of research on the subject in Sweden. This paper is an attempt to analyse what the students are offered to learn about the concept of function both in the classroom and in textbooks and what the students actually learn. The presentation is based on
Several plasticizing chemicals induce endocrine disrupting effects in humans, and the indoor environment is suggested to be a source of exposure. As children are particularly vulnerable to the effects from exposure to endocrine disrupting chemicals (EDCs), it is essential to monitor exposure to EDCs such as phthalates and non-phthalate plasticizers in indoor environments intended for use by childr
In this paper, we clarify, unpack, and ultimately resist what is perhaps the most prominent argument for the compatibility of free will and determinism: the epistemic argument for compatibilism. We focus on one such argument as articulated by David Lewis: (i) we know we are free, (ii) for all we know everything is predetermined, (iii) if we know we are free but for all we know everything is predet
The embrace of coronavirus disease 2019 (COVID-19) vaccine conspiracies has been linked to vaccine hesitancy. This study aimed to investigate the relationship between COVID-19 vaccine conspiracy theories and perceived vaccine effectiveness. The study utilized a longitudinal follow-up study in which adults in Chile completed surveys in December 2020 (T1) and May 2021 (T2). The psychometric properti
Non-governmental organisations (NGOs) increasingly enter into “partnerships” with states to implement human rights, a phenomenon that has been studied both as a necessary inclusion of civil society in human rights practice, and as a slippery slope towards a neoliberal state retreat. What remains to be studied is how this partnership practice shapes the concepts of human rights and their duty beare
BackgroundMuch longitudinal research has been carried out on non-suicidal self-injury (NSSI) during the last decades, but there still is a lack of studies of the individual developmental pathways of NSSI from adolescence into young adulthood. The aim of the present study was to investigate individual developmental pathways of repetitive non-suicidal self-injury (repNSSI) from adolescence into youn
Internationalization has become one of the main strategic goals of universities as part of their endeavors to prepare students for careers in a globalized world. However, the establishment of English-medium instruction (EMI) has raised concerns about the quality of teaching and learning, given that most stakeholders involved in the process are second language (L2) speakers of English. Therefore, a
Architecture is currently facing a period of transformational change which is driven by an increasing awareness of sustainability imperatives combined with technological advancements in the form of digitalisation of design and fabrication processes. These issues both introduce new layers of complexity and necessitate strategies to navigate them. This thesis explores an aspect of this transformatio
This article revisits and expands upon a previous phenomenographic study characterising the qualitatively different ways in which South African undergraduate physics students may experience the use of +/– signs in one-dimensional kinematics (1DK). We find the original categorisation as applicable for interpreting Swedish university-level students’ responses to 1DK questions. However, by way of a t
A technique is presented to measure the efficiency with which c-jets are mistagged as b-jets (mistagging efficiency) using tt¯ events, where one of the W bosons decays into an electron or muon and a neutrino and the other decays into a quark–antiquark pair. The measurement utilises the relatively large and known W→ cs branching ratio, which allows a measurement to be made in an inclusive c-jet sam
