Systematic Anomalies in Rainfall Intensity Estimates Over the Continental U.S.

Rainfall intensities during extreme events over the continental U.S. are compared for several advanced radar products. These products include: 1) TRMM spaceborne radar (PR) near surface estimates; 2) NOAA Next-Generation Quantitative Precipitation Estimation (QPE) very high-resolution (1 km) radar-only national mosaics (Q2); 3) very high-resolution instantaneous gauge adjusted radar national mosaics, which we have developed by applying gauge correction on the Q2 instantaneous radar-only products; and 4) several independent C-band dual-polarimetric radar-estimated rainfall samples collected with the ARMOR radar in northern Alabama. Though accumulated rainfall amounts are often similar, we find the satellite and the ground radar rain rate pdfs to be quite different. PR pdfs are shifted towards lower rain rates, implying a much larger stratiform/convective rain ratio than do ground radar products. The shift becomes more evident during strong continental convective storms and much less during tropical storms. Resolving the continental/maritime regime behavior and other large discrepancies between the products presents an important challenge. A challenge to improve our understanding of the source of the discrepancies, to determine the uncertainties of the estimates, and to improve remote-sensing estimates of precipitation in general

Aprendemos haciendo alimentos de calidad en organizaciones comunitarias

El Banco Alimentario La Plata es una organización comunitaria destinada a satisfacer las necesidades alimentarias de la población de bajos recursos. Es una sociedad civil de carácter social en la cual surge una serie de inquietudes explícitas vinculadas directamente con la factibilidad de cubrir ciertas necesidades. En este sentido, en el marco del proyecto de extensión Aprendemos Haciendo Alimentos de Calidad, instituido en los años 2020-2021, se propuso colaborar en la resolución de dichas problemáticas, a partir de la constitución de un equipo interdisciplinario que diera respuesta a la diversidad de situaciones a partir del trabajo colaborativo, permitiendo poner en valor los conocimientos de todos los participantes y pudiendo avanzar de esta manera hacia las metas propuestas.The BALP is a community organization created to meet the food needs of the low-income population. This is a civil society of a social nature which aims at analysing the possibilities of meeting these explicit needs through feasible actions. It is in this sense that in the framework of the extension project Aprendemos Haciendo Alimentos de Calidad, carried out during 2020-2021, it was proposed that we worked to solve these problems. The proposal involved collaborative work among the members of an interdisciplinary team that would respond to different situations, which allows the consideration and value of the participants’ knowledge and thus move forward towards the achievement of the goals set.Facultad de Ciencias Agrarias y ForestalesFacultad de Ciencias ExactasFacultad de Arte

Diseño y desarrollo del compostaje Bokashi con perspectiva de género para productoras del MTE rural en transición agroecológica

El cinturón hortícola de La Plata se constituye como uno de los polos de producción de alimentos para consumo interno más importantes de nuestro país. En esta propuesta, se trabaja específicamente con mujeres agricultoras, permitiendo poner en valor su trabajo, a la vez que construyendo saberes, prácticas y herramientas específicas que maximicen los resultados de su labor a través del diseño. En este sentido, la técnica del bokashi como un bioinsumo de fabricación propia en la producción fruti-hortícola es una estrategia sustentable para el ciclado e incorporación de nutrientes y microorganismos benéficos al suelo. Sin embargo en su elaboración es necesario palear frecuentemente la totalidad de la pila en el suelo, razón que limita la posibilidad de que las mujeres productoras lo lleven a cabo. Proponemos el diseño y auto-construcción del dispositivo “bokashiera” que elimina el “paleo”. La “bokashiera”, compuesta de materiales reciclados y de bajo costo, tiene la capacidad de rotar en forma manual sobre un soporte, sin ningún esfuerzo. A través de talleres teórico-prácticos organizados en la cooperativa proponemos el abordaje de la técnica del bokashi y la materialización a través del diseño de la “bokashiera” para empoderar a las mujeres del MTE Rural, logrando la apropiación no sólo material sino simbólica para colocarlas en un lugar de autonomía personal y social.Facultad de Trabajo Socia

Search for Anisotropy of Ultra-High Energy Cosmic Rays with the Telescope Array Experiment

We study the anisotropy of Ultra-High Energy Cosmic Ray (UHECR) events collected by the Telescope Array (TA) detector in the first 40 months of operation. Following earlier studies, we examine event sets with energy thresholds of 10 EeV, 40 EeV, and 57 EeV. We find that the distributions of the events in right ascension and declination are compatible with an isotropic distribution in all three sets. We then compare with previously reported clustering of the UHECR events at small angular scales. No significant clustering is found in the TA data. We then check the events with E>57 EeV for correlations with nearby active galactic nuclei. No significant correlation is found. Finally, we examine all three sets for correlations with the large-scale structure of the Universe. We find that the two higher-energy sets are compatible with both an isotropic distribution and the hypothesis that UHECR sources follow the matter distribution of the Universe (the LSS hypothesis), while the event set with E>10 EeV is compatible with isotropy and is not compatible with the LSS hypothesis at 95% CL unless large deflection angles are also assumed. We show that accounting for UHECR deflections in a realistic model of the Galactic magnetic field can make this set compatible with the LSS hypothesis.Comment: 10 pages, 9 figure

Measurement of the proton-air cross section with Telescope Array's Middle Drum detector and surface array in hybrid mode

In this work we are reporting on the measurement of the proton-air inelastic cross section sigma(inel)(p-air) using the Telescope Array detector. Based on the measurement of the sigma(inel)(p-air), the proton-proton cross section sigma(p-p) value is also determined at root s = 95(-8)(+5) TeV. Detecting cosmic ray events at ultrahigh energies with the Telescope Array enables us to study this fundamental parameter that we are otherwise unable to access with particle accelerators. The data used in this report are the hybrid events observed by the Middle Drum fluorescence detector together with the surface array detector collected over five years. The value of the sigma(inel)(p-air) is found to be equal to 567.0 +/- 70.5[Stat](-25)(+29)[Sys] mb. The total proton-proton cross section is subsequently inferred from Glauber formalism and the Block, Halzen and Stanev QCD inspired fit and is found to be equal to 170(-44)(+48)[Stat](-17)(+19)[Sys] mb.open20
