The impact of temperature and air velocity on the drying of pituca (Colocasia esculenta) sheets was investigated. The samples, 1.5 mm thick, were subjected to a tray dryer at three temperatures (45, 50 and 55 °C) and three air velocities (2.5; 3.0 and 3.5 m/s). After grinding the dried sheets, the physicochemical, microbiological and sensory properties of the pituca flour were analyzed. The findings indicated that the drying curves conformed to the exponential model proposed by Herdenson and Pabis, with a coefficient of determination greater than 96%. The optimum treatment, T9, used a temperature of 55 °C and a speed of 3.5 m/s. It showed a critical moisture of 1.53 g/g dry pituca, an equilibrium moisture of 0.9 g/g dry pituca, and a critical time of 20 minutes. Values for ash, moisture, mesophilic aerobes, molds and yeasts were recorded at 3.37%, 8.04%, 9.90x103 CFU/g, and 2.40x103 CFU/g respectively, with absence of Escherichia coli. At higher temperatures and air velocities, the best sensory ratings were obtained. In conclusion, these parameters result in superior quality for pituca flour in kinetic, physicochemical and sensory terms.

The present study aimed to determine the type of carbapenemase present in Enterobactales, Pseudomonas aeruginosa and Acinetobacter spp. isolated from patients hospitalized in the ICU of Hospital IV "Víctor Lazarte Echegaray", during the COVID-19 pan-demic. In this descriptive, observational and cross-sectional study, biological samples were collected from patients hospitalized in the ICU, processed in the Microbiology Diagnostic Laboratory of Hospital IV "Víctor Lazarte Echegaray". Antimicrobial identification and sensitivity were performed with the AutoScan-4 automated system, and the RESISIT-3 O.K.N K-SET cassettes were used to identify the type of carbapenemase. Of a total of 129 cultures, 58,9% were found to be resistant to at least one carbapenem (Meropenem or Imipenem), of which 59,2% were Enterobacterales, 26,3% were Pseudomonas aeruginosa and 14.5% were% Acinetobacter spp; when evaluating the presence of carbapenemases, it was found that 66 cultures (51,2%) presented carbapenemases; of which 28 are positive to KPC (42,4%), 25 to NDM (37,9%) and 13 to OXA-48 (19,7%). It is concluded that the presence of carbapenemasas in microbial cultures isolated from patient hospitalized I the intensive care unit exceeds the 30% reported in 2019 in South America.
A Formally Motivated Retrieval Framework Applied to the High-resolution Transmission Spectrum of HD 189733 b
Authors: Blain Doriann , Sánchez-López Alejandro , Mollière Paul 
Published: March 2024

Abstract
Ground-based high-resolution spectra provide a powerful tool for characterizing exoplanet atmospheres. However, they are greatly hampered by the dominating telluric and stellar lines, which need to be removed prior to any analysis. Such removal techniques (“preparing pipelines”) deform the spectrum; hence, a key point is to account for this process in the forward models used in retrievals. We develop a formal derivation on how to prepare froward models for retrievals, in the case where the telluric and instrumental deformations can be represented as a matrix multiplied element-wise with the data. We also introduce the notion of a “bias pipeline metric,” which can be used to compare the bias potential of preparing pipelines. We use the resulting framework to retrieve simulated observations of 1D and 3D exoplanet atmospheres and to reanalyze high-resolution (

We retrieve a broadened line shape, consistent with rotation- and wind-induced line broadening. Finally, we find a lower limit for the pressure of an opaque cloud consistent with a clear atmosphere, and we find no evidence for hazes.
A Unified Model for Bipolar Outflows from Young Stars: Kinematic and Mixing Structures in HH 30

Published: March 2024

Abstract
The young stellar source HH 30 is a textbook example of an ionic optical jet originating from a disk in an edge-on system shown by the Hubble Space Telescope. It has a remnant envelope in 12CO observed by the Atacama Large Millimeter/submillimeter Array. The optical jet is characterized by its narrow appearance, large line width at the base, and high temperature inferred from line diagnostics. Three featured structures can be identified, most evident in the transverse position–velocity diagrams: an extremely-high-velocity wide-angle wind component with large spectral widths in the optical, a very-low-velocity ambient surrounding medium seen in 12CO, and a low-velocity region traced by 12CO nested both in velocity and location between the primary wind and ambient environment. A layered cavity with multiple shells forms nested morphological and kinematic structures around the optical jet. The atomic gas originating from the innermost region of the disk attains a sufficient temperature and ionization to emit brightly in forbidden lines as an optical jet. The wide-angle portion expands, forming a low-density cavity. The filamentary 12CO encompassing the wind cavity is mixed and advected inward through the action of the magnetic interplay of the wide-angle wind with the molecular ambient medium. The magnetic interplay results in the layered shells penetrating deeply into the vast cavity of tenuous atomic wind material. The HH 30 system is an ideal manifestation of the unified wind model of Shang et al. (2020, 2023), with clearly distinguishable atomic and molecular species mixed through the atomic lightly ionized magnetized wind and the surrounding cold molecular ambient material.
Constraining the Onset Density for the QCD Phase Transition with the Neutrino Signal from Core-collapse Supernovae

Abstract
The occurrence of a first-order hadron–quark matter phase transition at high baryon densities is investigated in astrophysical simulations of core-collapse supernovae, to decipher yet incompletely understood properties of the dense matter equation of state (EOS) using neutrinos from such cosmic events. It is found that the emission of a nonstandard second neutrino burst, dominated by electron antineutrinos, is not only a measurable signal for the appearance of deconfined quark matter but also reveals information about the state of matter at extreme conditions encountered at the supernova (SN) interior. To this end, a large set of spherically symmetric SN models is investigated, studying the dependence on the EOS and the stellar progenitor. General relativistic neutrino-radiation hydrodynamics is employed featuring three-flavor Boltzmann neutrino transport and a microscopic hadron-quark hybrid matter EOS class. Therefore, the DD2 relativistic mean-field hadronic model is employed, and several variations of it, and the string-flip model for the description of deconfined quark matter. The resulting hybrid model covers a representative range of onset densities for the phase transition and latent heats. This facilitates the direct connection between intrinsic signatures of the neutrino signal and properties of the EOS. In particular, a set of linear relations has been found empirically. These potentially provide a constraint for the onset density of a possible QCD phase transition from the future neutrino observation of the next galactic core-collapse SN, if a millisecond electron anti-neutrino burst is present around or less than 1 s.
