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

Proton-emission branches of the 10+ isomer in the Tz=−1 nucleus 54Ni have been imaged with the active target and time projection chamber (ACTAR TPC) in an experiment conducted at the Grand Accélérateur National d'Ions Lourds (GANIL). The completed decay scheme allows derivation of the reduced transition strengths, B(E2;10+→8+) and B(E4;10+→6+), for the two competing γ-ray transitions. By means of

This book presents an invaluable collection of essays by eminent scholars from a wide variety of disciplines on the main issues currently confronting legal professions across the world.It does this through comparative analyses of the data provided by the reports on 46 countries in its companion volume: Lawyers in 21st-Century Societies: Vol. 1: National Reports, published in 2020. Together these v

This chapter is based on a document analysis of 632 issues of the Danish Bar and Law Society’s trade magazine published from 1976-2018, and interviews with lawyers from the Scandinavian countries. The empirical findings concerning the structures and rationales dominating and defining the trajectory of lawyers’ voluntary work for the last four decades suggest that voluntary work targeted at those m

Ramadan fasting is observed by most of the 1.8 billion Muslims around the world. It lasts for 1 month per the lunar calendar year and is the abstention from any food and drink from dawn to sunset. While recommendations on 'safe' fasting exist for patients with some chronic conditions, such as diabetes mellitus, guidance for patients with cardiovascular disease is lacking. We reviewed the literatur

Thoracic epidural analgesia (TEA) is an established gold standard for postoperative pain control especially following laparotomy and thoracotomy. The safety and efficacy of TEA is well known when the attention to patient selection is upheld. Recently, the use of fascial plane blocks (FPBs) has evolved as an alternative to TEA most likely because these blocks avoid problems such as neurological com

Calorie restriction (CR) is suggested to prevent the development of mammary tumors (MTs); however, the mechanism remains to be clarified. We aimed to determine the microRNA (miRNA) profile in mice applied to 2 different CR protocols; chronic (CCR) and intermittent (ICR) and follow the MT development. In addition, the roles of miRNAs involved in adiponectin and/or leptin signaling pathways were inv

The specific shear viscosity, η/ s, of the quark-gluon plasma formed in ultrarelativistic heavy-ion collisions at RHIC and LHC is estimated based on the progressive longitudinal broadening of transverse momentum two-particle correlators, G2, reported as a function of collision centrality by the STAR and ALICE experiments. Estimates are computed as a function of collision centrality using the Gavin

A chronicle describing the historical context and the development of ideas and experiments leading to the discovery of the back-bending phenomenon in rapidly rotating atomic nuclei some 50 years ago is presented. The moment of inertia of some atomic nuclei increases anomalously at a certain rotational frequency, revealing important clues to our understanding of nuclear structure. I highlight the d

A pseudo-velocity concept, based on the extension of a linear body, is defined by a special relativity experiment. It suggests an analogy with the covariance properties of Wiener's process, ultimately implying that the scaling behavior of (Gaussian) polymer solutions can be derived from a Brownian Relativity theory, as it was formerly put forward. An ad-hoc statistical interpretation of the result

BackgroundMany high-income countries have seen an increase in severe perineal trauma. Teaching strategies and conditions for learning during the active second stage of labour are scarcely described.AimTo describe midwifery preceptors and midwifery students’ experiences’ of teaching and learning how to manage the second stage of labour, with the specific aim of preventing severe perineal trauma.Met

High-energy heavy-ion collisions allow the Quark-Gluon Plasma (QGP) production and study, a state of high-density QCD matter in which quarks and gluons are no longer confined inside hadrons for a very short time. Different observables reveal an enhanced production of strange hadrons, signatures of collective effects and opacity to jets due to the QGP formation. However, collective effects and stra

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

Pneumatiska bromssystem i tunga fordon är oeffektiva ur energiperspektiv, artikeln beskriver mätningar som jämför pneumatiska och elektromekaniska bromssystem för en batterielektrisk buss.Electric powertrains increase efficiency in road vehicles and enable zero tailpipe emissions, but introduce practical limitations in on board energy storage capacity, due to the low energy density in battery systems when compared with chemical fuels in tanks. The increased powertrain efficiency and lower on-board energy storage levels place focus on other energy consumers in the vehicle system, su
