Published: February 2022

The use of Bacillus amyloliquefaciens based fungicide has increased along with the modernization of agriculture. On the other hand, freshwater culture is generally juxtaposed with agricultural land. This study was conducted to determine the fungicide's sublethal effect on the survival and haematologist of common carp and tilapia as non-target organisms. The method used was a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used are: (A) control (0 ppm fungicide), (B) 0.5 ppm fungicide, (C) 1 ppm fungicide, and (D) 10 ppm fungicide. Observation time is 96 hours. Survival, white blood cells, and red blood cells are analyzed using analysis of variance, while the feed response, shock response, and water quality are analyzed descriptively. The results showed that 10 ppm fungicide was not lethal to common carp and tilapia with a survival rate of almost 100%. During 96 hours of fungicide exposure, the average white blood cell (WBC) of common carp increased from 8.84-10.46 x 104 cells/mm3 to 9.56-11.48 x 104 cells/mm3. Meanwhile, the mean WBC of tilapia increased from 11.36-19.44 x 104 cells/mm3 to 20.52-37.38 x 104 cells/mm3. The average red blood cell (RBC) of common carp decreased from 6.60-7.01 x 106 cells/mm3 to 6.06-6.76 x 106 cells/mm3. Meanwhile, the mean RBC of tilapia decreased from 5.26-7.55 x 106 cells/mm3 to 2.21-3.76 x 106 cells/mm3. The results showed that the feed response did not change during the study, but the shock response decreased at 96 hours. Water quality during the study was still in the optimal range for common carp and tilapia culture. Key words : Bacillus amyloliquefaciens, fungicide, sublethal effect, common carp, tilapia

Children’s views on social distancing and playing on an adventure playground
Authors: King Pete , Gregory Chris 
Published: February 2022

Adventure playgrounds have provided an important play environment for children in the United Kingdom (UK) since the 1940s. Twenty-five children ages from 4 to 13 were asked how they would play if social distancing was introduced on their adventure playground. Using Piagetian classification as a framework, responses from children in the pre-operational stage were compliant, whilst in the operational stage, children were compliant but explained how they would adapt their play. For the formal operational stage, the responses were confrontational. The importance of obtaining children’s views challenges the original ‘blanket’ policy guidance within the UK on social distancing for all children in outdoor environments including an adventure playground and considering how children play when with their peers is more social play.

IRAM 30 m CO-line Observation toward the PeVatron Candidate G106.3+2.7: Direct Interaction between the Shock and the Molecular Cloud Remains Uncertain
Authors: Liu Qian-Cheng , Zhou Ping , Chen Yang 
Published: February 2022

Abstract
The supernova remnant (SNR) G106.3+2.7 was recently found to be one of the few potential Galactic hadronic PeVatrons. Aiming to test the solidity of the SNR’s association with the molecular clouds (MCs) that are thought to be responsible for hadronic interaction, we performed a new CO observation with the IRAM 30 m telescope toward its “belly” region, which is coincident with the centroid of the γ-ray emission. There is a filament structure in the local standard of rest velocity interval −8 to −5 km s−1 that nicely follows the northern radio boundary of the SNR. We have seen asymmetric broad profiles of 12CO lines, with widths of a few km s−1, along the northern boundary and in the “belly” region of G106.3+2.7, but similar 12CO-line profiles are also found outside the SNR boundary. Further, the low 12CO J = 2–1/J = 1–0 line ratios suggest the MCs are cool. Therefore, it is still uncertain whether the MCs are directly disturbed by the SNR shocks, but we do find some clues that the MCs are nearby and thus can still be illuminated by the protons that escaped from the SNR. Notably, we find an expanding molecular structure with a velocity of ∼3.5 km s−1 and a velocity gradient of the MCs across the SNR from ∼−3 to −7 km s−1, which could be explained as the effect of the wind blown by the SNR’s progenitor star.

Abstract
Sagittarius A* (Sgr A*), the Galactic Center supermassive black hole (SMBH), is one of the best targets in which to resolve the innermost region of an SMBH with very long baseline interferometry (VLBI). In this study, we have carried out observations toward Sgr A* at 1.349 cm (22.223 GHz) and 6.950 mm (43.135 GHz) with the East Asian VLBI Network, as a part of the multiwavelength campaign of the Event Horizon Telescope (EHT) in 2017 April. To mitigate scattering effects, the physically motivated scattering kernel model from Psaltis et al. (2018) and the scattering parameters from Johnson et al. (2018) have been applied. As a result, a single, symmetric Gaussian model well describes the intrinsic structure of Sgr A* at both wavelengths. From closure amplitudes, the major-axis sizes are ∼704 ± 102 μas (axial ratio ∼

) and ∼300 ± 25 μas (axial ratio ∼1.28 ± 0.2) at 1.349 cm and 6.95 mm, respectively. Together with a quasi-simultaneous observation at 3.5 mm (86 GHz) by Issaoun et al. (2019), we show that the intrinsic size scales with observing wavelength as a power law, with an index ∼1.2 ± 0.2. Our results also provide estimates of the size and compact flux density at 1.3 mm, which can be incorporated into the analysis of the EHT observations. In terms of the origin of radio emission, we have compared the intrinsic structures with the accretion flow scenario, especially the radiatively inefficient accretion flow based on the Keplerian shell model. With this, we show that a nonthermal electron population is necessary to reproduce the source sizes.

Abstract
Galaxy evolution is driven by a variety of physical processes that are predicted to proceed at different rates for different dark matter haloes and environments across cosmic times. A record of this evolution is preserved in galaxy stellar populations, which we can access using absorption-line spectroscopy. Here we explore the large LEGA-C survey (DR3) to investigate the role of the environment and stellar mass on stellar populations at z ∼ 0.6–1 in the COSMOS field. Leveraging the statistical power and depth of LEGA-C, we reveal significant gradients in D

4000 and Hδ EWs primarily depend on stellar mass, but they also depend on environment at fixed stellar mass. By splitting the sample into centrals and satellites, and in terms of star-forming galaxies and quiescent galaxies, we reveal that the significant environmental trends of D

4000 and Hδ EW, when controlling for stellar mass, are driven by quiescent galaxies. Regardless of being centrals or satellites, star-forming galaxies reveal D
n
4000 and Hδ EWs, which depend strongly on their stellar mass and are completely independent of the environment at 0.6 < z < 1.0. The environmental trends seen for satellite galaxies are fully driven by the trends that hold only for quiescent galaxies, combined with the strong environmental dependency of the quiescent fraction at fixed stellar mass. Our results are consistent with recent predictions from simulations that point toward massive galaxies forming first in overdensities or the most compact dark matter haloes.

Abstract
We present deep X-ray and radio observations of the fast blue optical transient (FBOT) AT 2020xnd/ZTF 20acigmel at z = 0.2433 from 13 days to 269 days after explosion. AT 2020xnd belongs to the category of optically luminous FBOTs with similarities to the archetypal event AT 2018cow. AT 2020xnd shows luminous radio emission reaching L

≈ 8 × 1029 erg s−1 Hz−1 at 20 GHz and 75 days post-explosion, accompanied by luminous and rapidly fading soft X-ray emission peaking at L
X ≈ 6 × 1042 erg s−1. Interpreting the radio emission in the context of synchrotron radiation from the explosion’s shock interaction with the environment, we find that AT 2020xnd launched a high-velocity outflow (v ∼ 0.1c–0.2c) propagating into a dense circumstellar medium (effective

w = 1000 km s−1). Similar to AT 2018cow, the detected X-ray emission is in excess compared to the extrapolated synchrotron spectrum and constitutes a different emission component, possibly powered by accretion onto a newly formed black hole or neutron star. These properties make AT 2020xnd a high-redshift analog to AT 2018cow, and establish AT 2020xnd as the fourth member of the class of optically luminous FBOTs with luminous multiwavelength counterparts.
