Panorama de las producciones vegetales intensivas de alimentos saludables – “Proalim Km 0”, en tiempos de pandemia por la Covid-19 – Parte 1. Predisposición de los consumidores de hortalizas, frutas y aromáticas medicinales a su producción, agroindustria y consumo

Given the importance that, for the health of the population, an adequate consumption of products of plant origin has, and in order to have a diagnosis on the intensive vegetable production of healthy foods (PVIAS) of proximity, at the level of urban family gardens and of commercial ventures, their production, processing, marketing and consumption preferences, in the current socio-economic and productive context, an inter-institutional survey called “ProALIM Km 0” was carried out. It was organized within the framework of the inter-institutional project CIAC-940186 (INTA – AUDEAS – CONADEV) “Intensive Vegetable Productions of Healthy Foods - PVIAS”, using Google form (Google Forms). The main objective of this work to know the habits, preferences and changes produced in the population, regarding the production, agroindustry and / or consumption of vegetables, fruits and medicinal aromatics (intensive vegetable productions - PVIAS), in the current socio-economic and productive context. The surveyed population demonstrated to know and have interest in the production, agribusiness and consumption of PVIAS, and it was detected that, in many cases, this interest is not specified in practice, especially in relation to the consumption of vegetables and water, in the that reality is, to a great extent, far from national and international recommendations. These differences would indicate that, from the institutions, actions must be carried out that make it possible to translate into practice, aspects that the population knows of their convenience.Dada la importancia que, para la salud de la población, tiene un adecuado consumo de productos de origen vegetal, y a fin de disponer de un diagnóstico sobre las producciones vegetales intensivas de alimentos saludables (PVIAS) de cercanía, a nivel de huertas urbanas familiares y de emprendimientos comerciales, su producción, elaboración, comercialización y preferencias de consumo, en el actual contexto socioeconómico y productivo, se llevó a cabo una encuesta interinstitucional denominada “ProALIM Km 0”. La misma se organizó en el marco del Proyecto interinstitucional CIAC-940186 (INTA–AUDEAS–CONADEV) “Producciones Vegetales Intensivas de Alimentos Saludables – PVIAS”, mediante formulario de Google (Google Forms). El objetivo central de este trabajo conocer los hábitos, preferencias y cambios producidos en la población, respecto de la produccin, agroindustria y/o consumo de hortalizas, frutas y aromáticas medicinales (producciones vegetales intensivas – PVIAS), en el actual contexto socioeconómico y productivo. La población encuestada demostró conocer y tener interés en la producción, agroindustria y consumo de PVIAS, y se detectó que, en muchos casos, dicho interés no se concreta en la práctica, especialmente en lo relacionado al consumo de vegetales y de agua, en los que la realidad dista, en gran medida, las recomendaciones nacionales e internacionales. Dichas diferencias estarían indicando que, desde las instituciones, deben llevarse a cabo acciones que hagan posible que se plasme en la práctica, aspectos que la población sabe de su conveniencia.EEA BalcarceFil: Bellaccomo, María Carolina.

A Compact Dication Source for Ba2+^{2+} Tagging and Heavy Metal Ion Sensor Development

We present a tunable metal ion beam that delivers controllable ion currents in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed by sequential atomic evaporation and single or multiple electron impact ionization, followed by acceleration into a sensing region. Controllability of the ionic charge state is achieved through tuning of electrode potentials that influence the retention time in the ionization region. Barium, lead, and cobalt samples have been used to test the system, with ion currents identified and quantified using a quadrupole mass analyzer. Realization of a clean $\mathrm{Ba^{2+}}$ ion beam within a bench-top system represents an important technical advance toward the development and characterization of barium tagging systems for neutrinoless double beta decay searches in xenon gas. This system also provides a testbed for investigation of novel ion sensing methodologies for environmental assay applications, with dication beams of Pb$^{2+}$ and Cd$^{2+}$ also demonstrated for this purpose

Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background

The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitational waves. While general relativity allows for only two tensor gravitational-wave polarizations, general metric theories can additionally predict two vector and two scalar polarizations. The polarization of gravitational waves is encoded in the spectral shape of the stochastic gravitational-wave background, formed by the superposition of cosmological and individually unresolved astrophysical sources. Using data recorded by Advanced LIGO during its first observing run, we search for a stochastic background of generically polarized gravitational waves. We find no evidence for a background of any polarization, and place the first direct bounds on the contributions of vector and scalar polarizations to the stochastic background. Under log-uniform priors for the energy in each polarization, we limit the energy densities of tensor, vector, and scalar modes at 95% credibility to Ω0T<5.58×10-8, Ω0V<6.35×10-8, and Ω0S<1.08×10-7 at a reference frequency f0=25 Hz. © 2018 American Physical Society

All-sky search for long-duration gravitational wave transients with initial LIGO

We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July 7, 2009 and October 20, 2010, with a total observational time of 283.0 days and 132.9 days, respectively. The search targets gravitational wave transients of duration 10-500 s in a frequency band of 40-1000 Hz, with minimal assumptions about the signal waveform, polarization, source direction, or time of occurrence. All candidate triggers were consistent with the expected background; as a result we set 90% confidence upper limits on the rate of long-duration gravitational wave transients for different types of gravitational wave signals. For signals from black hole accretion disk instabilities, we set upper limits on the source rate density between 3.4×10-5 and 9.4×10-4 Mpc-3 yr-1 at 90% confidence. These are the first results from an all-sky search for unmodeled long-duration transient gravitational waves. © 2016 American Physical Society

Search for gravitational waves from Scorpius X-1 in the second Advanced LIGO observing run with an improved hidden Markov model

We present results from a semicoherent search for continuous gravitational waves from the low-mass x-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wandering. This search improves on previous HMM-based searches of LIGO data by using an improved frequency domain matched filter, the J-statistic, and by analyzing data from Advanced LIGO's second observing run. In the frequency range searched, from 60 to 650 Hz, we find no evidence of gravitational radiation. At 194.6 Hz, the most sensitive search frequency, we report an upper limit on gravitational wave strain (at 95% confidence) of h095%=3.47×10-25 when marginalizing over source inclination angle. This is the most sensitive search for Scorpius X-1, to date, that is specifically designed to be robust in the presence of spin wandering. © 2019 American Physical Society

Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift during the LIGO-Virgo Run O3b

We search for gravitational-wave signals associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced Virgo (2019 November 1 15:00 UTC-2020 March 27 17:00 UTC). We conduct two independent searches: A generic gravitational-wave transients search to analyze 86 GRBs and an analysis to target binary mergers with at least one neutron star as short GRB progenitors for 17 events. We find no significant evidence for gravitational-wave signals associated with any of these GRBs. A weighted binomial test of the combined results finds no evidence for subthreshold gravitational-wave signals associated with this GRB ensemble either. We use several source types and signal morphologies during the searches, resulting in lower bounds on the estimated distance to each GRB. Finally, we constrain the population of low-luminosity short GRBs using results from the first to the third observing runs of Advanced LIGO and Advanced Virgo. The resulting population is in accordance with the local binary neutron star merger rate. © 2022. The Author(s). Published by the American Astronomical Society
