The goal of this study is to gain a better understanding of residents' personal concerns about improper plastic disposal and to give voice to their thoughts about the Toledo City Government's prospective ideas and approaches for minimizing the city's plastic pollution. Residents of Magdugo, Toledo City, Cebu, Philippines, have been subjected to increasing levels of plastic pollution. The vast number of discarded plastic items that eventually end up in canals, drainage systems, and city streets, generating flooding that poses a severe challenge in agriculture, health, and sanitation. According to the findings, the city's inefficient waste management system has resulted in a massive accumulation of durable plastics. Toledo City, on the other hand, has improved waste management, restored cleanliness, and minimized the environmental effect of plastics through regulatory initiatives. The majority of citizens in Toledo City have enthusiastically embraced the city's ordinance prohibiting the use of plastic bags. Plastic bag littering has been shown to decrease throughout the city, resulting in a cleaner and healthier environment. The city's achievement might serve as a model for other places that have yet to abolish plastic bags. As a result of a cleaner and healthier environment, people have become more productive, and tourists have returned to the city, contributing to the city's economic growth. Policy management in the reduction of plastic pollution.

Kompost post is an organic fertilizer derived from plant residues and animal waste. This fertilizer is environmentally friendly, increases soil fertility, and can increase the income of farmers. The people of Ngreco Village are farmers' villages. Planting vegetables and secondary crops are a solution during the Covid-19 pandemic. The majority of the population raises goats. To improve the quality of creativity and good planting results, namely by providing education, counseling, and training. Making compost from goat manure is very important and needed by plants because it contains nutrients such as nitrogen (N), phosphorus (P), and potassium (K) as well as micronutrients including calcium, magnesium, sulfur, sodium, iron, and copper. relatively high plant requirements and soil fertility. Technology transfer through facilitation increases public knowledge and awareness about the importance of compost fertilizers for plants. However, the implementation is still lacking due to limited materials. So people only rely on assistance from the government or apply without the composting process.
Kompos merupakan pupuk organik yang berasal dari sisa tanaman dan kotoran hewan. Pupuk merupakan media tanam yang ramah lingkungan, menambah kesuburan tanah, dan mampu menambah pendapatan peternak. Desa Ngreco merupakan desa petani. Menanam sayuran dan palawija menjadi solusi di masa pandemi Covid-19 bagi masyarakat Desa Ngreco. Mayoritas penduduknya juga memelihara kambing. Untuk meningkatkan kualitas, kreativitas, dan hasil penanaman yang baik adalah dengan memberikan edukasi, penyuluhan, dan pelatihan. Membuat pupuk kompos dari kotoran kambing merupakan kegiatan yang sangat penting dan dibutuhkan oleh tanaman karena mengandung zat hara seperti nitrogen (N), fosfor (P), dan kalium (K) serta unsur hara mikro di antaranya kalsium, magnesium, belerang, natrium, besi, dan tembaga relatif tinggi yang dibutuhkan tanaman untuk kesuburan tanah. Transfer teknologi dapat dilakukan melalui fasilitasi menambah pengetahuan masyarakat untuk meningkatkan kesadaran tentang pentingnya pupuk kompos pada tanaman. Keterbatasan bahan menjadi pemicu rendahnya tingkat kesadaran dalam pengimplementasian, sehingga masyarakat hanya mengandalkan bantuan dari pemerintah atau mengaplikasikan tanpa proses pengomposan.

The lack of planning on the development of the Mosque Al Mujahidien Yosodadi complex causes the undirected process of building so that the mosque layout and its supporting rooms are less synergistic, and the use of development funds becomes inefficient. Aiming to assist the mosque management team (takmir) in formulating the site concept of Mosque Al Mujahidien as the basis of its development stage, we conducted interviews, surveys, updating the existing conditions of the mosque building, site analysis, and identification of space requirements. The main result of the assistance is the formulation of ta’mir ideas to accommodate the relationship of multi dimensional activities (hablumminallah, hablumminannaas, and hablumminal ‘alam) to be adaptive with the development of commercial activities around. Therefore, the footprint can be a reference for the mosque management team in making a master plan and carrying out the stages of the physical development buildings is more visionary integrated. Finally, the expense of development funds becomes more efficient.
Minimnya perencanaan pembangunan kompleks Masjid Al Mujahidien Yosodadi menyebabkan proses pembangunan yang tidak terarah sehingga layout masjid dan ruang-ruang penunjangnya kurang sinergis, dan penggunaan dana pembangunan menjadi tidak efisien. Bertujuan untuk membantu tim pengelola masjid (takmir) dalam merumuskan konsep tapak Masjid Al Mujahidien sebagai dasar tahap pengembangannya, kami melakukan wawancara, survey, pemutakhiran kondisi eksisting bangunan masjid, analisis lokasi, dan identifikasi persyaratan ruang. Hasil utama dari kegiatan ini adalah perumusan ide-ide ta’mir untuk mengakomodir relasi aktivitas multi dimensional (hablumminallah, hablumminannaas, dan hablumminal ‘alam) agar adaptif dengan perkembangan aktivitas komersial di sekitar. Oleh karena itu, tapak tersebut dapat menjadi acuan bagi tim pengelola masjid dalam membuat master plan dan melaksanakan tahapan pembangunan fisik bangunan yang lebih visioner terintegrasi.

HEART AND VESSEL REMODELING IN DIFFERENT AGE GROUPS OF PATIENTS WITH ARTERIAL HYPERTENSION
Authors: Kandilova V. N. 
Published: August 2022

Actuality. It is known that each of the factors (arterial hypertension (AH) and age) has a negative effect on the remodeling of both the heart and vessels, while their combined effect has not been sufficiently studied. The aim. Assessment of manifestations of cardiac and vascular remodeling (by the example of common carotid arteries (СCA) and vasomotor endothelium function (right brachial artery)) in patients with AH degree I-III in different age groups.Material and methods. The study involved 124 (86 men and 38 women) patients at the age from 27 to 81 years (average age of patients 55.7+1.01 years) with AH degree I-III. The presence and variant of myocardial remodeling with calculation of criteria of left ventricular hypertrophy (LVH), myocardial mass (MM) and MM index (MMI) of LV by indexation to the patient’s body surface area were studied in all patients by means of echocardiographic investigation (EchoCG) using the Vivid S5 3Sc-RS echocardiograph with a multifrequency sensor 2.0-3.5 MHz. Normal values of MM were considered to be 67-162 grams (g) for women and 88-224 for men, and MMI - not more than 95 and 115 g/m2, respectively. Types of LVH were determined according to recommendations of Pugliese N.R. et al. (2017), being subdivided into concentric (C) and eccentric (E) LVH. Ultrasound scanning was used to investigate CCA on both sides. The results of reactive hyperemia test on the right brachial artery and blood lipid profile were studied with the calculation of atherogenicity coefficient (AC). The data analysis was carried out with the help of Statistica 12 application package with determination of mean values (M), minimum, maximum and mean error (m), median and interquartile range for the CCA intima-media thickness (IMT). The Spearman rank correlation coefficient (r) was used to estimate the relationship between these variables. The significance level of all statistical tests was accepted at p˂0.05.The results of the study confirmed the presence of cardiac and vascular remodeling in patients with AH of different degrees with the tendency to increase in older age groups. The CCA remodeling parameter values were also significantly higher in the groups of middle-aged and elderly persons, some of which also had atherosclerotic plaques (AP). The number of patients with disturbed endothelial vasomotor function also somewhat increased with age.Conclusion. Thus, the age of the examined patients with AH had a significant influence on aggravation of the heart and vessel remodeling processes and increasing frequency of endothelial dysfunction development

Abstract
We report the analysis of microlensing event OGLE-2017-BLG-1038, observed by the Optical Gravitational Lensing Experiment, Korean Microlensing Telescope Network, and Spitzer telescopes. The event is caused by a giant source star in the Galactic Bulge passing over a large resonant binary-lens caustic. The availability of space-based data allows the full set of physical parameters to be calculated. However, there exists an eightfold degeneracy in the parallax measurement. The four best solutions correspond to very-low-mass binaries near (

) the boundary between stars and brown dwarfs. A conventional analysis, with scaled uncertainties for Spitzer data, implies a very-low-mass brown-dwarf binary lens at a distance of 2 kpc. Compensating for systematic Spitzer errors using a Gaussian process model suggests that a higher mass M-dwarf binary at 6 kpc is equally likely. A Bayesian comparison based on a galactic model favors the larger-mass solutions. We demonstrate how this degeneracy can be resolved within the next 10 years through infrared adaptive-optics imaging with a 40 m class telescope.
X-Raying the Birth of Binary Neutron Stars and Neutron Star–Black Hole Binaries
Authors: Kashiyama Kazumi , Sawada Ryo , Suwa Yudai 
Published: August 2022

Abstract
We consider fallback accretion after an ultrastripped supernova (USSN) that accompanies formation of a binary neutron star (BNS) or a neutron star–black hole binary (NS–BH). The fallback matter initially accretes directly to the nascent NS, while it starts to accrete to the circumbinary disk, typically 0.1–1 day after the onset of the USSN explosion. The circumbinary disk mass further accretes, forming mini disks around each compact object, with a super-Eddington rate up to a few years. We show that such a system constitutes a binary ultraluminous X-ray source, and a fraction of the X-rays can emerge through the USSN ejecta. We encourage follow-up observations of USSNe within ≲100 Mpc and ∼100–1000 days after the explosion using Chandra, XMM Newton, and NuSTAR, which could detect the X-ray counterpart with time variations representing the properties of the nascent compact binary, e.g., the orbital motion of the binary, the spin of the NS, and/or the quasiperiodic oscillation of the mini disks.
Single Pulse Dispersion Measure of the Crab Pulsar
Authors: Lewandowska N. , Demorest P. B. , McLaughlin M. A. , Kilian P. , Hankins T. H. 
Published: August 2022

Abstract
We investigate the use of bright single pulses from the Crab pulsar to determine separately the dispersion measure (DM) for the Main Pulse and Interpulse components. We develop two approaches using cross-correlation functions (CCFs). The first method computes the CCF of the total intensity of each of the 64 frequency channels with a reference channel and converts the time lag of maximum correlation into a DM. The second method separately computes the CCF between every pair of channels for each individual bright pulse and extracts an average DM from the distribution of all channel-pair DMs. Both methods allow the determination of the DM with a relative uncertainty of better than 10−5 and provide robust estimates for the uncertainty of the best-fit value. We find differences in DM between the Main Pulse, the Low Frequency Interpulse, and the High Frequency Interpulse using both methods in a frequency range from 4 to 6 GHz. Earlier observations of the High Frequency Interpulse carried out by Hankins et al. (2016) resulted in DMHFIP–DMMP of 0.010 ± 0.016 pc cm−3. Our results indicate a DMHFIP–DMMP of 0.0127 ± 0.0011 pc cm−3 (with DMcomp being the DM value of the respective emission component), confirming earlier results with an independent method. During our studies we also find a relation between the brightness of single pulses in the High Frequency Interpulse and their DM. We also discuss the application of the developed methods on the identification of substructures in the case of Fast Radio Bursts.

Abstract
The three-rung distance ladder, which calibrates Type Ia supernovae (SNe Ia) through stellar distances linked to geometric measurements, provides the highest precision direct measurement of the Hubble constant. In light of the Hubble tension, it is important to test the individual components of the distance ladder. For this purpose, we report a measurement of the Hubble constant from 35 extragalactic Cepheid hosts measured by the SH0ES team, using their distances and redshifts at cz ≤ 3300 km s−1, instead of any more distant SNe Ia, to measure the Hubble flow. The Cepheid distances are calibrated geometrically in the Milky Way, NGC 4258, and the Large Magellanic Cloud. Peculiar velocities are a significant source of systematic uncertainty at z ∼ 0.01, and we present a formalism for both mitigating and quantifying their effects, making use of external reconstructions of the density and velocity fields in the nearby universe. We identify a significant source of uncertainty originating from different assumptions about the selection criteria of this sample, whether distance or redshift limited, as it was assembled over three decades. Modeling these assumptions yields central values ranging from H
0 = 71.7 to 76.4 km s−1 Mpc−1. Combining the four best-fitting selection models yields

Electron-scale Magnetic Peaks Upstream of Mercury’s Bow Shock: MESSENGER Observations
Authors: Chen Y. Q. , Wang G. Q. , Wu M. Y. , Xiao S. D. , Zhang T. L. 
Published: August 2022

Abstract
Electron-scale magnetic peaks (ESMPs) with spatial sizes less than one local ion gyroradius have been recently revealed to exist in the terrestrial magnetosheath and solar wind at 1 au. Whether they widely exist in the astrophysical plasma is unclear. Here, we investigate the magnetic peaks with a period of 0.1–100 s upstream of Mercury’s bow shock by using the magnetic field data from the MESSENGER spacecraft. Based on the distribution of their durations, these magnetic peaks can be divided into two groups: one with durations less than 0.6 s and the other with durations larger than 0.6 s. The durations in each group obey a log-normal distribution. The magnetic peaks with durations less than 0.6 s are inferred to be electron scale, suggesting that ESMPs exist in the solar wind at Mercury’s orbit. The median duration of these ESMPs is ∼0.3 s. The ESMPs have a larger occurrence rate near the bow shock and prefer to occur when the ambient interplanetary magnetic field (IMF) can be connected to the bow shock, which suggests that the foreshock could be one source region of these ESMPs. Their occurrence rate also tends to be larger when the IMF strength is weaker. Our observations also suggest that some ESMPs originate from the upstream solar wind. The properties of the ESMPs found here could help to shed light on their generation mechanisms and their roles in the astrophysical plasma.

Abstract
Wide-field Infrared Survey Explorer all-sky survey has discovered a new population of hot dust-obscured galaxies (Hot DOGs), which have been confirmed to be dusty quasars. Previous statistical studies have found significant overdensities of submillimeter and mid-IR-selected galaxies around Hot DOGs, indicating they may reside in dense regions. Here we present the near-infrared (J and K

, to select distant red galaxies (DRGs). We find a significant excess of number density of DRGs in the W1835+4355 field compared to three control fields, by a factor of about two. The overdensity of red galaxies around W1835+4355 is consistent with the multiwavelength environment of Hot DOGs, suggesting that Hot DOGs may be a good tracer for dense regions at high redshift. We find that W1835+4355 does not reside in the densest region of the dense environment traced by itself. A possible scenario is that W1835+4355 is undergoing a merging process, which lowers the local number density of galaxies in its surrounding region.
Evidence for a Dense, Inhomogeneous Circumstellar Medium in the Type Ia SNR 0519-69.0

Published: August 2022

Abstract
We perform an expansion study of the Balmer-dominated outer shock of the SNR 0519−69.0 in the LMC by using a combination of new Hubble Space Telescope (HST) WFC3 imagery obtained in 2020 and archival ACS images from 2010 and 2011. Thanks to the very long time baseline, our proper motion measurements are of unprecedented accuracy. We find a wide range of shock velocities, with the fastest shocks averaging 5280 km s−1 and the slowest grouping of shocks averaging just 1670 km s−1. We compare the Hα images from HST with X-ray images from Chandra and mid-IR images from Spitzer, finding a clear anticorrelation between the brightness of the remnant in a particular location and the velocity of the blast wave at that location, supporting the idea that the bright knots of X-ray and IR emission result from an interaction with a dense inhomogeneous circumstellar medium. We find no evidence for X-ray emission, thermal or nonthermal, associated with the fastest shocks, as expected if the fastest velocities are the result of the blast wave encountering the lower density ambient medium of the LMC. We derive an age of the remnant of ≤670 ± 70 yr, consistent with results derived from previous investigations.
