Published: April 2024

Integrated crop-livestock systems are being increasingly used to intensify food production and make it more sustainable. On the other hand, most studies have focused on extensive systems. This paper analyzed the effects of different managements on soil and plants in an intensive integrated system for milk production. An experiment of management systems was installed in southern Brazil, Rio Grande do Sul, on a Latossolo Vermelho (Oxisol), in 2015 to evaluate: rotational grazing of dairy cows in the winter; rotational grazing of dairy cows in winter followed by soil chiseling; and ungrazed area (control). Soil physical properties and yields of crops were evaluated. Trampling by dairy cows increased soil bulk density by 24 % (0.0-0.05 m), but did not influence yields of subsequent soybean or maize. Chiseling reduced the bulk density of the uppermost layer by 19 %, but did not affect the yields of subsequent crops. It was concluded that in years with abundant water, dairy cattle grazing in an integrated crop-livestock system in Southern Brazil compacts the soil surface, but does not compromise the soil physical processes related to the growth and development of subsequent crops.

In recent years, there has been a significant overfishing of fish and aquaculture in the Black Sea, which has led today to a general decline in fishing in our region. Catches of sturgeon, salmon, bull, mullet and other Black Sea fish, both marine and migratory, have decreased. Some species of Black Sea ichthyofauna: listed in the Red Book of Ukraine; are in a depressed state; in recent years, their commercial fishing has been prohibited. In addition, from February 24, 2022 until today, a rather dangerous ecological situation has developed in the Black Sea, which requires and requires the most thorough control and regulation of checking the content of harmful substances of exogenous origin in fish and aquaculture, which can pose a danger to human health and animals
Safe and high-quality live sea fish, regardless of the place of catch, must be mobile. well-fed, skin condition without damage, shiny eyes and red gills, and most importantly, a pleasant smell. The main methods of storing fish are: cooling, freezing, freezing, salting, drying, drying. Each of these methods is based on suppressing or completely stopping the vital activity of microorganisms that are in the fish's body. Over time, fish begin to spoil due to enzymatic processes and the vital activity of microorganisms.

Investigation of 3% Binahong (Anredera cordifolia) Leaf Extract Nanogel on the Alveolar Bone Healing: BMP-2 Modulation in Rat Models
Authors: Bernard Bernard , Syafruddin Ilyas  , Olivia Avriyanti Hanafiah  
Published: April 2024

Background: Alveolar bone healing relies on osteoblasts activity and differentiation, with bone morphogenetic protein-2 (BMP-2) playing a crucial regulatory role. Binahong leaf extract (BLE) has demonstrated efficacy in bone healing due to its rich phytochemical composition. Nanogel offers enhanced bioavailability and targeted release to effectively deliver therapeutic agents. This study aims to assess the impact of 3% BLE nanogel on BMP-2 expression in tooth extraction socket healing.
Methods: Thirty male Wistar rat underwent anaesthesia for the extraction of their lower incisors to induce alveolar bone healing. Subjects were randomly assigned into treatment (BLE nanogel) and control (base nanogel) group. Five rats from each group were respectively sacrificed at 7, 14, and 28 days after procedures. BMP-2 expression was assessed by performing immunohistochemistry analysis using BMP antibody reagent. Data were analysed using chi-square.
Results: The analysis of BMP-2 expression showed no significant difference between treatment and control groups on days 7, 14, and 28 (p>0,05). However, a subtle increase was observed in the treatment group throughout observation period.
Conclusion: Application of 3% BLE nanogel may enhance the expression of BMP-2, even though it was not significantly increase. The findings underscore the complex interplay between Binahong leaf extract, nanogel and BMP-2 expression.
Probing 3D Magnetic Fields Using Thermal Dust Polarization and Grain Alignment Theory
Authors: Hoang Thiem , Truong Bao 
Published: April 2024

Abstract
Magnetic fields are ubiquitous in the Universe and are thought to play an important role in various astrophysical processes. Polarization of thermal emission from dust grains aligned with the magnetic field is widely used to measure the 2D magnetic field projected onto the plane of the sky, but its component along the line of sight is not yet constrained. Here, we introduce a new method to infer 3D magnetic fields using thermal dust polarization and grain alignment physics. We first develop a physical model of thermal dust polarization using the modern grain alignment theory based on the magnetically enhanced radiative torque alignment theory. We then test this model with synthetic observations of magnetohydrodynamic simulations of a filamentary cloud with our updated POLARIS code. Combining the tested physical polarization model with synthetic polarization, we show that the B-field inclination angles can be accurately constrained by the polarization degree from synthetic observations. Compared to the true 3D magnetic fields, our method based on grain alignment physics is more accurate than the previous methods that assume uniform grain alignment. This new technique paves the way for tracing 3D B-fields using thermal dust polarization and grain alignment theory and for constraining dust properties and grain alignment physics.
Latitude-dependent Atmospheric Waves and Long-period Modulations in Luhman 16 B from the Longest Light Curve of an Extrasolar World

Published: April 2024

Abstract
In this work, we present the longest photometric monitoring of up to 1200 hr of the strongly variable brown dwarf binaries Luhman 16 AB and provide evidence of ±5% variability on a timescale of several to hundreds of hours for this object. We show that short-period rotational modulation around 5 hr (k = 1 wavenumber) and 2.5 hr (k = 2 wavenumber) dominate the variability under 10 hr, where the planetary-scale wave model composed of k = 1 and k = 2 waves provides good fits to both the periodograms and light curve. In particular, models consisting of three to four sine waves could explain the variability of the light-curve durations up to 100 hr. We show that the relative range of the k = 2 periods is narrower compared to the k = 1 periods. Using simple models of zonal banding in solar system giants, we suggest that the difference in period range arises from the difference in wind-speed distribution at low and mid-to-high latitudes in the atmosphere. Last, we show that Luhman 16 AB also exhibits long-period ±5% variability, with periods ranging from 15 hr up to 100 hr over the longest monitoring of this object. Our results for the k = 1 and k = 2 waves and long-period evolution are consistent with previous 3D atmosphere simulations, demonstrating that both latitude-dependent waves and slow-varying atmospheric features are potentially present in Luhman 16 AB atmospheres and are a significant contribution to the light-curve modulation over hundreds of rotations.
Radiation Process in Relativistic MHD Waves: The Case of Circularly Polarized Alfvén Waves
Authors: Goto Ryota , Asano Katsuaki 
Published: April 2024

Abstract
Turbulence in highly magnetized plasma can be relativistic and induce an electric field comparable to the background magnetic field. Such a strong electric field can affect the emission process of nonthermal electrons. As the first step toward elucidating the emission process in relativistic turbulence, we study the radiation process of electrons in relativistic circularly polarized Alfvén waves. While the induced electric field boosts the average energy of low-energy electrons with a Larmor radius smaller than the wavelength, the emissivity for such electrons is suppressed because of the elongated gyromotion trajectory. The trajectory of high-energy electrons is shaken by the small-scale electric field, which enhances the emissivity. Since the effective Lorentz factor of E × B drift is

in the circularly polarized Alfvén waves, the deviation from the standard synchrotron emission is not so prominent. However, a power-law energy injection in the waves can produce a concave photon spectrum, which is similar to the GeV extra component seen in GRB spectra. If the turbulence electric field is responsible for the GeV extra component in GRBs, the estimates of the typical electron energy and magnetic field should be largely altered.
The Sun Remains Relatively Refractory Depleted: Elemental Abundances for 17,412 Gaia RVS Solar Analogs and 50 Planet Hosts

Published: April 2024

Abstract
The element abundances of stars, particularly the refractory elements (e.g., Fe, Si, and Mg), play an important role in connecting stars to their planets. Most Sun-like stars do not have refractory abundance measurements since obtaining a large sample of high-resolution spectra is difficult with oversubscribed observing resources. In this work we infer abundances for C, N, O, Na, Mn, Cr, Si, Fe, Ni, Mg, V, Ca, Ti, Al, and Y for solar analogs with Gaia Radial Velocity Spectrometer (RVS) spectra (R = 11,200) using TheCannon, a data-driven method. We train a linear model on a reference set of 34 stars observed by Gaia RVS with precise abundances measured from previous high-resolution spectroscopic efforts (R > 30,000–110,000). We then apply this model to several thousand Gaia RVS solar analogs. This yields abundances with average upper limit precisions of 0.04–0.1 dex for 17,412 stars, 50 of which are identified planet (candidate) hosts. We subsequently test the relative refractory depletion of these stars with increasing element condensation temperature compared to the Sun. The Sun remains refractory depleted compared to other Sun-like stars regardless of our current knowledge of the planets they host. This is inconsistent with theories of various types of planets locking up or sequestering refractories. Furthermore, we find no significant abundance differences between identified close-in giant planet hosts, giant planet hosts, and terrestrial/small planet hosts with the rest of the sample within our precision limits. This work demonstrates the utility of data-driven learning for future exoplanet composition and demographics studies.

Published: April 2024

Abstract
The conventional accretion disk lore is that magnetized turbulence is the principal angular momentum transport process that drives accretion. However, when dynamically important large-scale magnetic fields thread an accretion disk, they can produce mass and angular momentum outflows, known as winds, that also drive accretion. Yet, the relative importance of turbulent and wind-driven angular momentum transport is still poorly understood. To probe this question, we analyze a long-duration (1.2 × 105

/c) simulation of a rapidly rotating (a = 0.9) black hole feeding from a thick (H/r ∼ 0.3), adiabatic, magnetically arrested disk (MAD), whose dynamically important magnetic field regulates mass inflow and drives both uncollimated and collimated outflows (i.e., winds and jets, respectively). By carefully disentangling the various angular momentum transport processes within the system, we demonstrate the novel result that disk winds and disk turbulence both extract roughly equal amounts of angular momentum from the disk. We find cumulative angular momentum and mass accretion outflow rates of

This result suggests that understanding both turbulent and laminar stresses is key to understanding the evolution of systems where geometrically thick MADs can occur, such as the hard state of X-ray binaries, low-luminosity active galactic nuclei, some tidal disruption events, and possibly gamma-ray bursts.
Deriving X-Ray Line Profiles for Massive-star Winds from Momentum-conserving Dynamical Working Surface Solutions
Authors: Gunderson Sean J. , Gayley Kenneth G. 
Published: April 2024

Abstract
We present a general procedure for deriving a line-profile model for massive-star X-ray spectra that captures the dynamics of the wind more directly. The basis of the model is the analytic solution to the problem of variable jets in Herbig–Haro objects given by Cantó et al. In deriving our model, we generalize this jet solution to include flows with a prescribed nonzero acceleration for the context of radiatively driven winds. We provide example line profiles generated from our model for the case of sinusoidal velocity and mass-ejection variations. The example profiles show the expected shape of massive-star X-ray emission lines, as well as interesting but complicated trends with the model parameters. This establishes the possibility that observed X-rays could be a result of temporal variations seeded at the wind base, rather than purely generated intrinsically within the wind volume, and can be described via a quantitative language that connects with the physical attributes of those variations, consistently with the downstream momentum-conserving nature of radiatively cooled shocked radial flows.
Simulating X-Ray Reverberation in the Ultraviolet-emitting Regions of Active Galactic Nuclei Accretion Disks with Three-dimensional Multifrequency Radiation Magnetohydrodynamic Simulations
Authors: Secunda Amy , Jiang 姜 Yan-Fei 燕飞 , Greene Jenny E. 
Published: April 2024

Abstract
Active galactic nuclei (AGN) light curves observed with different wave bands show that the variability in longer wavelength bands lags the variability in shorter wavelength bands. Measuring these lags, or reverberation mapping, is used to measure the radial temperature profile and extent of AGN disks, typically with a reprocessing model that assumes X-rays are the main driver of the variability in other wavelength bands. To demonstrate how this reprocessing works with realistic accretion disk structures, we use 3D local shearing box multifrequency radiation magnetohydrodynamic simulations to model the UV-emitting region of an AGN disk, which is unstable to the magnetorotational instability and convection. At the same time, we inject hard X-rays (>1 keV) into the simulation box to study the effects of X-ray irradiation on the local properties of the turbulence and the resulting variability of the emitted UV light curve. We find that disk turbulence is sufficient to drive intrinsic variability in emitted UV light curves and that a damped random walk model is a good fit to this UV light curve for timescales >5 days. Meanwhile, X-ray irradiation has negligible impact on the power spectrum of the emitted UV light curve. Furthermore, the injected X-ray and emitted UV light curves are only correlated if there is X-ray variability on timescales >1 day, in which case we find a correlation coefficient r = 0.34. These results suggest that if the opacity for hard X-rays is scattering dominated as in the standard disk model, hard X-rays are not the main driver of reverberation signals.
Les maisons d’architecte en Région de Bruxelles-Capitale (1830-1970)
Authors: Voorde Stephanie Van de , Raaffels Linsy , Wee Barbara Van der , Bertels Inge 
Published: April 2024

Les maisons d’architecte constituent une catégorie de logements à part, qui revêtent une signification particulière en tant que « carte de visite » de l’architecte, projet expérimental, aboutissement ou synthèse de l’ensemble de son œuvre, englobant des caractéristiques stylistiques, géographiques, techniques, sociales et autres. Toutefois, afin de saisir pleinement l’importance et la valeur ajoutée de ce genre architectural, il est essentiel de disposer d’un cadre théorique et typologique bien défini pour comprendre les maisons d’architecte. Sur la base des données recueillies à partir d’inventaires et de documents existants, de recherches dans les archives et de visites sur le terrain, un vaste registre dans lequel sont recensées 370 maisons d’architecte de la Région de Bruxelles-Capitale a été établi, qui constitue le point de départ de l’analyse. Ce registre se concentre sur la période de 1830 à 1970, au cours de laquelle la construction de maisons d’architecte et de logements en général s’est intensifiée. Il comprend des maisons d’architecte emblématiques et célèbres, ainsi que des exemples moins connus, dans des proportions à peu près égales : nombre de ces édifices n’étaient pas répertoriés auparavant et peuvent désormais être qualifiés à juste titre de maisons d’architecte. Témoignant de la diversité de ces maisons, le registre constitue la base indispensable pour apprécier de manière approfondie les différents cas, ainsi que la maison d’architecte en tant que type de bâtiment particulier.

Cet article propose d’examiner les conditions qui ont participé à rendre envisageable, pour certains artistes, de concevoir des propositions créatrices sous forme de modification d’œuvres existantes. Il s’avère instructif d’examiner le traitement différencié des réutilisations d’œuvres dans une démarche créative, d’analyser les spécificités des modifications considérées comme « recevables » et des actes condamnés en tant que vandalisme. Cela invite à questionner les conditions auxquelles une action artistique est qualifiée de vandalisme.
Shine bright. Vetro e (un po’ di) ceramica invetriata a Venezia e nelle aree limitrofe tra VI e XI secolo
Authors: Ferri Margherita 
Published: April 2024

La prima parte dell’intervento riguarda una disamina di vecchi e nuovi dati derivati dalle ricerche condotte dall’Università Ca’ Foscari Venezia con il fine di sintetizzare quanto noto su produzione e consumo degli oggetti in vetro a Venezia e aree limitrofe tra V e XI secolo. Si tratta di un periodo particolarmente avaro di rinvenimenti e quanto emerso dagli scavi di Jesolo, Torcello, San Francesco del Deserto, San Lorenzo d’Ammiana, San Pietro in Castello, Santa Maria e Donato a Murano, Sant’Ilario di Mira costituisce un buon punto di partenza per descrivere il consumo di oggetti in vetro nei secoli di formazione della città. A seguire viene proposto un breve stato dell’arte sulle produzioni ceramiche invetriate altomedievali (CVP e CVS) nel medesimo areale e periodo. L’articolo sviluppa maggiormente la trattazione dei dati relativi alla produzione vitrea. Il ricorso al modello proposto per la produzione della ceramica invetriata in monocottura si mostra fondamentale per mettere a confronto queste due categorie di oggetti e evidenziare un possibile sostrato comune in cui questi manufatti trovano utilizzo e diffusione.
