No full textThe importance of fall prevention particularly in Latin America and the Caribbean, and specifically in
Ecuador, where falls are a significant cause of disability and hospital care in this population. The main
objective is to apply the nursing process, based on the NANDA Taxonomy, to prevent falls at the "Amawta
Wasi Samay" Gerontological Center during the period from October 2023 to February 2024. To achieve this
objective, a quantitative and descriptive, focusing the research on the collection and analysis of data on the
frequency of falls and the demographic characteristics of older adults, using the Virginia Henderson model.
The study population included 29 elderly residents of the center, selected under specific inclusion and
exclusion criteria. Data collection was carried out through a nursing assessment guide based on Virginia
Henderson's 14 needs. Nursing diagnoses identified ranged from impaired gas exchange to risk of impaired
skin integrity, and personalized care plans were developed in collaboration with a multidisciplinary team. The
evaluation of the care plans confirmed a significant reduction in the risk of falls, validating the effectiveness
of the applied nursing process.

Our distorted view of magnetars: application of the resonant cyclotron scattering model
No full textThe X-ray spectra of the magnetar candidates are customarily fitted with an empirical, two component model: an absorbed blackbody and a power-law. However, the physical interpretation of these two spectral components is rarely discussed. It has been recently proposed that the presence of a hot plasma in the magnetosphere of highly magnetized neutron stars might distort, through efficient resonant cyclotron scattering, the thermal emission from the neutron star surface, resulting in production of non-thermal spectra. Here we discuss the Resonant Cyclotron Scattering (RCS) model, and present its XSPEC implementation, as well as preliminary results of its application to Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
Modeling the broadband persistent emission of magnetars
No full textIn this paper, we discuss our first attempts to model the broadband persistent emission of magnetars within a self-consistent, physical scenario. We present the predictions of a synthetic model that we calculated with a new Monte Carlo 3D radiative code. The basic idea is that soft thermal photons (e.g. emitted by the star surface) can experience resonant cyclotron upscattering by a population of relativistic electrons treated in the twisted magnetosphere. Our code is specifically tailored to work in the ultra-magnetized regime; polarization and QED effects are consistently accounted for, as well different configurations for the magnetosphere. We discuss the predicted spectral properties in the 0.1-1000 keV range, the polarization properties, and we present the model application to a sample of magnetars soft X-ray spectra
Dense matter in neutron stars with eXTP
No full textAng Li et al.In this white paper, we present the potential of the enhanced X-ray timing and polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, exploring regimes not directly accessible to terrestrial experiments. By observing a diverse population of neutron stars—including isolated objects, X-ray bursters, and accreting systems—eXTP’s unique combination of timing, spectroscopy, and polarimetry enables high-precision measurements of compactness, spin, surface temperature, polarimetric signals, and timing irregularity. These multifaceted observations, combined with advances in theoretical modeling, pave the way toward a comprehensive description of the properties and phases of dense matter from the crust to the core of neutron stars. Under development by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Sciences, the eXTP mission is planned to be launched in early 2030.This work was supported by China’s Space Origins Exploration Program.

Accreting Pulsars: Mixing-up Accretion Phases in Transitional Systems
No full textIn the last 20 years our understanding of the millisecond pulsar (MSP)
population changed dramatically. Thanks to RXTE, we discovered that neutron
stars in LMXBs spins at 200-750 Hz frequencies, and indirectly confirmed the
recycling scenario, according to which neutron stars are spun up to ms periods
during the LMXB-phase. In the meantime, the continuous discovery of
rotation-powered MSPs in binary systems in the radio and gamma-ray band (mainly
with the Fermi LAT) allowed us to classify these sources into two "spiders"
populations, depending on the mass of their companion stars: Black Widow, with
very low-mass companion stars, and Redbacks, with larger companions possibly
filling their Roche lobes but without accretion. It was soon regained that MSPs
in short orbital period LMXBs are the progenitors of the spider populations of
rotation-powered MSPs, although a direct link between accretion- and
rotation-powered MSPs was still missing. In 2013 XMM-Newton spotted the X-ray
outburst of a new accreting MSP (IGR J18245-2452) in a source that was
previously classified as a radio MSP. Follow up observations of the source when
it went back to X-ray quiescence showed that it was able to swing between
accretion- to rotation-powered pulsations in a relatively short timescale (few
days), promoting this source as the direct link between the LMXB and the radio
MSP phases. Following discoveries showed that there exists a bunch of sources,
which alternates X-ray activity phases, showing X-ray pulsations, to radio-loud
phases, showing radio pulsations, establishing a new class of MSPs: the
Transitional MSP. In this review we describe these exciting discoveries and the
properties of accreting and transitional MSPs, highlighting what we know and
what we have still to learn about in order to fully understand the (sometime
puzzling) behavior of these systems and their evolutive connection (abridged)
Science objectives of the Einstein Probe mission
No full textWeimin Yuan et al.The Einstein Probe (EP) is an interdisciplinary mission of time-domain and X-ray astronomy. Equipped with a wide-field lobster-eye X-ray focusing imager, EP will discover cosmic X-ray transients and monitor the X-ray variability of known sources in 0.5–4 keV, at a combination of detecting sensitivity and cadence that is not accessible to the previous and current wide-field monitoring missions. EP can perform quick characterisation of transients or outbursts with a Wolter-I X-ray telescope onboard. In this paper, the science objectives of the EP mission are presented. EP is expected to enlarge the sample of previously known or predicted but rare types of transients with a wide range of timescales. Among them, fast extragalactic transients will be surveyed systematically in soft X-rays, which include γ-ray bursts and their variants, supernova shock breakouts, and the predicted X-ray transients associated with binary neutron star mergers. EP will detect X-ray tidal disruption events and outbursts from active galactic nuclei, possibly at an early phase of the flares for some. EP will monitor the variability and outbursts of X-rays from white dwarfs, neutron stars and black holes in our and neighbouring galaxies at flux levels fainter than those detectable by the current instruments, and is expected to discover new objects. A large sample of stellar X-ray flares will also be detected and characterised. In the era of multi-messenger astronomy, EP has the potential of detecting the possible X-ray counterparts of gravitational wave events, neutrino sources, and ultra-high energy γ-ray and cosmic ray sources. EP is expected to help advance the studies of extreme objects and phenomena revealed in the dynamic X-ray universe, and their underlying physical processes. Besides EP’s strength in time-domain science, its follow-up telescope, with excellent performance, will also enable advances in many areas of X-ray astronomy.We would like to thank a large number of colleagues, many of whom are not listed as co-authors of this paper, for stimulating discussions on the science objectives and science cases of the EP mission over the past ten years.

Beyond Blame—Mens Rea and Regulatory Crime
No full textIn the first part of this Article, the Author briefly outlines the conceptual underpinnings of the common law approach to mens rea, with its blame focus, and the Supreme Court\u27s early efforts to develop a different approach in interpreting regulatory criminal statutes. The Author begins the second part of this Article with Lambert v. California, in which the Court staked out the constitutional limits for the employment of strict liability in public welfare or regulatory crimes, and, first employed notice-based mens rea. This part goes on to examine the ensuing cases in which the Court, at least implicitly, fleshes out the notice analysis that should guide the courts in deciding whether Congress intended strict liability or some level of mens rea in enacting regulatory criminal statutes. The Author concludes with Liparota v. United States, the case in which the Court departed from the emerging construct, which had distinguished blame-based and notice-based mens rea. This part then charts the doctrinal confusion that has resulted from this conflation of blame and notice in the Court\u27s mens rea analysis, confusion that is apparent not only in its own cases but also those of the circuit courts as they confront this vexatious problem

Fables d'Ésope
No full textFrom the original Favole published in 2011 by Topipittori in Milan. Here is a large-format (9 x 13¼) landscape -- rather than portrait -- book. I feel as though I have known it before, but I cannot find it in the database. The cover has a cat looking suspiciously around a table of fable characters, among whom is a stork dipping her beak deep into a tall glass. The back cover advertises correctly: Vingt fables amusantes, parfois cruelles, des plus connues aux plus surprenantes…. The illustrations are indeed provocative, starting with the first fable's dog sick from devouring a snail. Are we seeing his insides or the woods in which he found the snail? In FC, three foxes rejoice in carnival costume over the fresh piece of meat teased away from the crow, who holds his hands high in outrage. In DS, we can see the fish start to pick at the floating piece of meat. My favorite in the book is Prométhée et les hommes. Since animals outnumbered people, Zeus asked Prometheus to transform a number of the former into the latter. They have human form but bestial souls. Rea mixes human and animal faces nicely here. TMCM has the country rat, perched in a flower, turning his head toward a slightly open door. The cover pictures turns out to be a doubting illustration of the fable in which a just lion king has all the animals come together in peace. Rea suggests nicely that this plan may not work. I wonder why many fable books are published because they have little new to offer; I do not have that question about this excellent book!This is a hardbound book (hard cover)Language note: FrenchTraduit du grec ancien par Émile Chambr

Careers in Sports Science
No full textThis book is aimed at students who are currently studying sports science at undergraduate level or studying BTECs in sport or sport and exercise science. The purpose of the book is to answer the big question:
What do you do with a sports science degree?
It is common that students know that they want to work in sport and work with people but are not sure exactly what they can do. This can affect their motivation while they study as they have no clear goal to work towards.
Based on interviews with 20 people who work in sports related occupations this is designed to provide direction and guidance to enable students to make informed decisions about what they could do with their qualification. The case studies include people who work to support performance athletes, such as a sports nutritionist, sport psychologist, sports analyst, exercise physiologist and a strength and conditioning coach. Also included are cases studies of sports coaches, personal trainers and teachers as well as broader career options such as sports massage therapy, sports development and sports journalism and broadcasting. Many of the people chosen as case studies work with Olympic or professional athletes.
As part of the case studies the importance of developing personal skills needed to work with athletes and other people are discussed. These discussions form the basis of a key chapter about the personal skills needed to work in sporting environments that are often unpredictable, complex and challenging. There is also important advice on how personal skills can be developed whilst studying and what else you should do during your studies to make yourself more employable.
There is an introductory chapter on the options for students who want to study sports science, or similar courses, at degree level with a focus on whether A-level or BTEC qualifications will be more beneficial to them. This chapter also assesses the value of degree level study to an individual’s career. There is a concluding chapter that examines how to apply for jobs and prepare for interviews once you have gained your qualification.
The author, Simon Rea, has worked as a performance coach and personal trainer as well as teaching in both higher and further education for over 25 years. He is a senior fellow of the Higher Education Academy and has written or contributed significantly to 14 books related to sports science
