Arrival Directions of Cosmic Rays above 32 EeV from Phase One of the Pierre Auger Observatory

A promising energy range to look for angular correlations between cosmic rays of extragalactic origin and their sources is at the highest energies, above a few tens of EeV (1 EeV equivalent to 10^(18) eV). Despite the flux of these particles being extremely low, the area of similar to 3000 km^(2) covered at the Pierre Auger Observatory, and the 17 yr data-taking period of the Phase 1 of its operations, have enabled us to measure the arrival directions of more than 2600 ultra-high-energy cosmic rays above 32 EeV. We publish this data set, the largest available at such energies from an integrated exposure of 122,000 km^(2) sr yr, and search it for anisotropies over the 3.4 pi steradians covered with the Observatory. Evidence for a deviation in excess of isotropy at intermediate angular scales, with similar to 15 degrees Gaussian spread or similar to 25 degrees top-hat radius, is obtained at the 4 sigma significance level for cosmic-ray energies above similar to 40 EeV

Searches for Ultra-High-Energy Photons at the Pierre Auger Observatory

The Pierre Auger Observatory, which is the largest air-shower experiment in the world, offers unprecedented exposure to neutral particles at the highest energies. Since the start of data collection more than 18 years ago, various searches for ultra-high-energy (UHE, E greater than or similar to 10^(17) eV) photons have been performed, either for a diffuse flux of UHE photons, for point sources of UHE photons or for UHE photons associated with transient events such as gravitational wave events. In the present paper, we summarize these searches and review the current results obtained using the wealth of data collected by the Pierre Auger Observatory

Search for Ultra-high-energy Photons from Gravitational Wave Sources with the Pierre Auger Observatory

A search for time-directional coincidences of ultra-high-energy (UHE) photons above 10 EeV with gravitational wave (GW) events from the LIGO/Virgo runs O1 to O3 is conducted with the Pierre Auger Observatory. Due to the distinctive properties of photon interactions and to the background expected from hadronic showers, a subset of the most interesting GW events is selected based on their localization quality and distance. Time periods of 1000 s around and 1 day after the GW events are analyzed. No coincidences are observed. Upper limits on the UHE photon fluence from a GW event are derived that are typically at & SIM;7 MeV cm(-2) (time period 1000 s) and & SIM;35 MeV cm(-2) (time period 1 day). Due to the proximity of the binary neutron star merger GW170817, the energy of the source transferred into UHE photons above 40 EeV is constrained to be less than 20% of its total GW energy. These are the first limits on UHE photons from GW sources

Comunicação terapêutica no cuidado pré-operatório de mastectomia Comunicación terapéutica en la atención pre-operatoria de mastectomía Therapeutic communication in perioperative care of mastectomy

Relato de experiência sobre a prática docente-assistencial em hospital de oncologia, com o propósito refletir sobre o desenvolvimento da comunicação terapêutica do (a) enfermeiro (a) na unidade de internação pré-operatória de mulheres mastectomizadas. Constatou-se que o exercício da comunicação terapêutica configura-se uma prática favorável, porquanto estabelece o vínculo enfermeiro-paciente, sendo a paciente produtora do próprio cuidado. Compreendendo a fragilidade da paciente nesta fase, o (a) enfermeiro (a) assume compromisso de preestabelecer os cuidados de enfermagem em parceria, de forma a atender às necessidades da paciente, e com vistas, principalmente, à autonomia do cuidado. Diante disto, apresenta-se uma proposta de assistência de enfermagem gerenciada e fundamentada em uma relação recíproca de cuidado participativo e humanizante.<br>Relato de experiencia sobre la práctica docente-asistencial en el hospital de oncología con el fin de reflexionar sobre el desarrollo de la terapia del enfermero en el hospital preoperatorio de las mujeres mastectomizadas. Se ha señalado que la práctica de la comunicación terapéutica establece una práctica favorable, establece una relación enfermero-paciente, quedándose la paciente como la productora de la propia atención. La comprensión de la fragilidad de la paciente en esta etapa, el enfermero tiene el compromiso previamente a los cuidados de enfermería en colaboración con el fin de satisfacer a las necesidades de la paciente, y su objetivo principal, la autonomía de la atención. Frente a esto, se presenta una propuesta de atención de enfermería y gerenciada basada en una relación de mutuo cuidado participativo y humanizante.<br>The authors report their experience as teacher-nurse for years in oncologic hospital with the aim of enabling reflection on the development of nursing therapeutic communication at the hospital preoperative unit for mastectomized women. It was found that the practice of therapeutic communication becomes a favorable practice, because establish the nurse-patient relationship, with patient producing his own care. Understanding the fragility of the patient at this stage, the nurse takes commitment to predefine the nursing care in partnership, in order to meet the patient needs, aiming to, mainly, the autonomy of care. In this way, the authors present a proposal for nursing managed care based on a mutal relationship, human and participatory care
