Authors: Marcondes de Godoy Marcelo , Rodrigues Neto José 
Published: December 2022

O leite de ovelha tem ganhado espaço na produção de diversos queijos, principalmente pelo alto valor nutricional. O objetivo deste trabalho foi realizar a análise sensorial do queijo frescal e temperado de leite de ovelha Santa Inês. Para a produção do queijo as ovelhas foram ordenhadas e o leite processado no setor de Agroindústria, com pasteurização lenta a 65 ºC por 30 minutos e resfriados a 40 ºC. Em seguida, foi adicionado 10 mL de coalho e manteve-se o leite em repouso até a coagulação. A coalhada foi cortada e dessorada, adicionando sal na proporção de cerca de 3% do peso da massa. A massa foi separada em duas partes equivalentes, temperando apenas uma das metades com 30 g de orégano. Posteriormente essas duas composições, foram colocadas em formas, formando dois tipos de queijo: o queijo temperado e o queijo frescal. Para avaliação dos tratamentos foi aplicada a análise sensorial com 80 provadores não treinados, aplicando uma Escala Hedônica de 9 pontos para os parâmetros cor, sabor, textura, aroma e aspecto geral. Também foi determinado o índice de aceitabilidade (IA) para os parâmetros avaliados. Os resultados da análise sensorial mostraram que o queijo frescal temperado apresentou melhores resultados nas avaliações de aroma e sabor que o queijo frescal (P<0,05). Ambos os tratamentos apresentaram uma boa aceitação, sendo que o queijo temperado obteve notas maiores para todos os parâmetros analisados. Houve uma superioridade sensorial e maior aceitabilidade do queijo temperado em relação ao queijo frescal. Tanto o queijo de leite de ovelha frescal temperado quanto o queijo frescal apresentaram boa aceitabilidade, o que permite sua produção e consumo.

Abstract
Formation of an ultra-thin nickel-germanide (Ni-germanide) film on a SiO2 film has been attempted with stacking structures of Ni with various thicknesses formed on Ge films with thicknesses of 4 nm or 20 nm and annealing in an N2 ambient condition. Physical analyses revealed that the ultra-thin Ni-germanide films with smooth surfaces could be formed on the SiO2 film after annealing at 400 °C without depending on the Ni thickness on the 4 nm thick Ge films. In the formation, reductive and oxidative reactions occurred in the films, which are quite important for determining a composition of the Ni-germanide.

Abstract
Effective strategies for improving the performance of a droplet-based electricity generator (DEG) remain a challenge. Herein, we propose to introduce an intermediate layer of cyclic transparent optical polymer (CYTOP) by adjusting the thickness, injecting ionized ions into the surface, and increasing the surface area. We observed the positive effects of the introduction of a CYTOP layer on outputs, especially with a greater thickness, surface ionized-air modification and larger surface area, which could promote the practical application of DEG in energy harvesting.

Abstract
Hybrid GaInAsP/SOI ridge waveguide Fabry–Pérot lasers with reduced thermal resistance were fabricated and measured. The lasers were formed by room-temperature surface-activated bonding of InP and silicon-on-insulator wafers. Thin SiO2 film was introduced as ridge-sidewall insulation to increase heat flow to the p-electrode side-metal. By incorporating a thermal shunt structure and Au electroplating, a single-facet output power of 20 mW and lasing operation up to 110 °C were achieved for a cavity length of 2.0 mm under continuous-wave conditions. The proposed structure showed low thermal resistance of 14.3 K W−1 and a threshold current density of approximately 0.7 kA cm−2.

This article explores the possibility of using optical absorption spectroscopy and fluorescence to detect wear products in used motor oils of marine engines. This task is relevant for diagnosing the state of marine equipment. The aim of the work was to develop a method for detecting and determining the concentration of ferromagnetic particles of wear products in used engine oil by analyzing changes in the optical density spectra depending on the wavelength when the sample is placed in an external magnetic field. The results obtained are novel. The expected mechanism for increasing the transparency of used oils in a magnetic field is described. The possibility of determining the concentration of magnetic particles, and hence the degree of wear of engine components during operation, is shown. The results of a study of the fluorescence spectra of fresh and used motor oils are presented, and changes in the amplitude and shift of the spectra of oils containing wear products are analyzed. The results presented in the work were repeated during the reproduction of experiments, correctly processed by modern mathematical methods, and are reliable.
Internal attention is the only retroactive mechanism for controlling precision in working memory
Authors: Serin Fatih , Günseli Eren 
Published: December 2022

AbstractRecent research has suggested that humans can assert control over the precision of working memory (WM) items. However, the mechanisms that enable this control are unclear. While some studies suggest that internal attention improves precision, it may not be the only factor, as previous work also demonstrated that WM storage is disentangled from attention. To test whether there is a precision control mechanism beyond internal attention, we contrasted internal attention and precision requirements within the same trial in three experiments. In every trial, participants memorized two items briefly. Before the test, a retro-cue indicated which item would be tested first, thus should be attended. Importantly, we encouraged participants to store the unattended item with higher precision by testing it using more similar lure colors at the probe display. Accuracy was analyzed on a small proportion of trials where the target-lure similarity, hence the task difficulty, was equal for attended and unattended items. Experiments 2 and 3 controlled for output interference by the first test and involuntary precision boost by the retro-cue, respectively. In all experiments, the unattended item had lower accuracy than the attended item, suggesting that individuals were not able to remember it more precisely than the attended item. Thus, we conclude that there is no precision control mechanism beyond internal attention, highlighting the close relationship between attentional and qualitative prioritization within WM. We discuss the important implications of these findings for our understanding of the fundamentals of WM and WM-driven behaviors.

Evidence for the Disruption of a Planetary System During the Formation of the Helix Nebula

Abstract
The persistence of planetary systems after their host stars evolve into their post-main-sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit infrared excess emission and/or spectral absorption lines associated with a reservoir of dust (or planetesimals) and its accretion. However, most white dwarfs are too cool to sufficiently heat any circumstellar dust to detectable levels of emission. The Helix Nebula (NGC 7293) is a young, nearby planetary nebula; observations at mid- and far-infrared wavelengths have revealed excess emission associated with its central white dwarf (WD 2226-210). The origin of this excess is ambiguous. It could be a remnant planetesimal belt, a cloud of comets, or the remnants of material shed during the post-asymptotic giant branch (post-AGB) phase. Here we combine infrared (Stratospheric Observatory for Infrared Astronomy, Spitzer, Herschel) and millimeter (Atacama Large Millimeter/submillimeter Array) observations of the system to determine the origin of this excess using multiwavelength imaging and radiative transfer modeling. We find the data are incompatible with a compact remnant planetesimal belt or post-AGB disk, and conclude the dust most likely originates from deposition by a cometary cloud. The measured dust mass, and lifetime of the constituent grains, implies disruption of several thousand Hale–Bopp equivalent comets per year to fuel the observed excess emission around the Helix Nebula’s white dwarf.

Abstract
Young stellar populations provide a record of past star formation, and by establishing their members’ dynamics and ages, it is possible to reconstruct the full history of star formation events. Gaia has greatly expanded the number of accessible stellar populations, with one of the most notable recently discovered associations being Cepheus Far North (CFN), a population containing hundreds of members spanning over 100 pc. With its proximity (d ≲ 200 pc), apparent substructure, and relatively small population, CFN represents a manageable population to study in depth, with enough evidence of internal complexity to produce a compelling star formation story. Using Gaia astrometry and photometry combined with additional spectroscopic observations, we identify over 500 candidate CFN members spread across seven subgroups. Combining ages from isochrones, asteroseismology, dynamics, and lithium depletion, we produce well-constrained ages for all seven subgroups, revealing a largely continuous 10 Myr star formation history in the association. By tracing back the present-day populations to the time of their formation, we identify two spatially and dynamically distinct nodes in which stars form, one associated with β Cephei, which shows mostly co-spatial formation, and one associated with EE Draconis with a more dispersed star formation history. This detailed view of star formation demonstrates the complexity of the star formation process, even in the smallest of regions.
Probability of Forming Gaps in the GD-1 Stream by Close Encounters of Globular Clusters
Authors: Doke Yuka , Hattori Kohei 
Published: December 2022

Abstract
One of the most intriguing properties of the GD-1 stellar stream is the existence of three gaps. If these gaps were formed by close encounters with dark matter subhalos, the GD-1 stream opens an exciting window through which we can see the size, mass, and velocity distributions of the dark matter subhalos in the Milky Way. However, in order to use the GD-1 stream as a probe of the dark matter substructure, we need to disprove that these gaps are not due to the perturbations from baryonic components of the Milky Way. Here we ran a large number of test-particle simulations to investigate the probability that each of the known globular clusters (GCs) can form a GD-1-like gap, by using the kinematical data of the GD-1 stream and GCs from Gaia early data release 3 and by fully taking the observational uncertainty into account. We found that the probability that all of the three gaps were formed by GCs is as low as 1.7 × 10−5, and the expected number of gaps formed by GCs is only 0.057 in our fiducial model. Our result highly disfavors a scenario in which GCs form the gaps. Given that other baryonic perturbers (e.g., giant molecular clouds) are even less likely to form a gap in the retrograde-moving GD-1 stream, we conclude that at least one of the gaps in the GD-1 stream was formed by dark matter subhalos if the gaps were formed by flyby perturbations.
Central Star Formation in Early-type Galaxy I Zw 81 in the Bootes Void

Published: December 2022

Abstract
The origin of star formation in customarily passively evolving early-type massive galaxies is poorly understood. We present a case study of a massive galaxy, I Zw 81, inside the Bootes void. The void galaxy is known to host active galactic nuclei (AGN). Our detailed 2D decomposition of the surface brightness distribution in the Canada France Hawaii Telescope (CFHT) g and r bands revealed multiple structural components such as a nuclear point source, a bar, a ring, and an inner exponential disk followed by an outer low surface brightness disk. I Zw 81 turns out to be a disk-dominated galaxy with lenticular morphology. The modeling of the multiwavelength spectral energy distribution shows that the galaxy is star-forming (SF), and belongs to the blue cloud. We find that the optical (g−r) color of the bar is bluer than the disks, and the far- and near-ultraviolet emission inside the galaxy observed with Imaging Telescope onboard AstroSat is concentrated in the central few kpc region enclosing the bar. The strong bar might be playing a pivotal role in driving the gas inflow and causing SF activity in tandem with the minor merger-like interactions as evident from the deep CFHT data. The low-luminosity AGN is insufficient to quench the central SF. The results are peculiar from the standpoint of a massive barred lenticular galaxy.

Abstract
The solar wind is known to be highly structured in space and time. Observations from Parker Solar Probe have revealed an abundance of so-called magnetic switchbacks within the near-Sun solar wind. In this Letter, we use a high-resolution, adaptive-mesh, magnetohydrodynamics simulation to explore the disturbances launched into the solar wind by intermittent/bursty interchange reconnection and how they may be related to magnetic switchbacks. We find that repeated ejection of plasmoid flux ropes into the solar wind produces a curtain of propagating and interacting torsional Alfvénic waves. We demonstrate that this curtain forms when plasmoid flux ropes dynamically realign with the radial field as they are ejected from the current layer and that this is a robust effect of the 3D geometry of the interchange reconnection region. Simulated flythroughs of this curtain in the low corona reveal an Alfvénic patch that closely resembles observations of switchback patches, but with relatively small magnetic field deflections. Therefore, we suggest that switchbacks could be the solar wind imprint of intermittent interchange reconnection in the corona, provided an in situ process subsequently amplifies the disturbances to generate the large deflections or reversals of radial field that are typically observed. That is to say, our results indicate that a combination of low-coronal and inner-heliospheric mechanisms may be required to explain switchback observations.

Alors qu’il y a pénurie de moyens pour répondre aux souffrances des enfants et aux attentes des parents, la priorité est imposée au diagnostic et au soin de troubles dits neurodéveloppementaux.
La interseccionalidad en el trabajo agrícola estacional: el caso de Huelva en tiempos de COVID-19
Authors: Güell Berta 
Published: December 2022

El COVID-19 ha visibilizado más que nunca las deficiencias estructurales del sistema agroalimentario mundial. El enclave agrícola de Huelva no es ninguna excepción. Partiendo del escenario pre-COVID y añadiendo los efectos de la pandemia, este artículo analiza los procesos de discriminación y abuso enraizados en la naturaleza y el modus operandi del programa español de trabajadores temporales (GECCO). En particular, examina cómo estos procesos de discriminación se reflejan en tres aspectos clave del programa: contratación, condiciones de trabajo y condiciones de vida. Gracias a la perspectiva interseccional y a las aportaciones feministas al capitalismo ecología-mundo, el análisis arroja luz sobre la mutua constitución de diferentes ejes de desigualdad (p.e. maternidad, etnicidad, origen rural) en las prácticas de discriminación y explotación que sufren las mujeres marroquíes. A su vez, examina cómo estas desigualdades entrecruzadas se ubican geográficamente en un contexto temporal y espacial específico que juega un papel en la construcción de relaciones de poder a nivel estructural. El artículo se nutre de un reciente trabajo de campo basado en entrevistas en profundidad con distintos actores clave como parte de un proyecto de investigación europeo sobre esquemas de gobernanza y migración circular (ADMIGOV).
