Authors: Zboralski Antoine , Saadia Hara , Novinscak Amy , Filion Martin 
Published: March 2022

Rhizosphere colonization by phytobeneficial Pseudomonas spp. is pivotal in triggering their positive effects on plant health. Many Pseudomonas spp. Determinants, involved in rhizosphere colonization, have already been deciphered. However, few studies have explored the role played by specific plant genes in rhizosphere colonization by these bacteria. Using isogenic Arabidopsis thaliana mutants, we studied the effect of 20 distinct plant genes on rhizosphere colonization by two phenazine-producing P. chlororaphis strains of biocontrol interest, differing in their colonization abilities: DTR133, a strong rhizosphere colonizer and ToZa7, which displays lower rhizocompetence. The investigated plant mutations were related to root exudation, immunity, and root system architecture. Mutations in smb and shv3, both involved in root architecture, were shown to positively affect rhizosphere colonization by ToZa7, but not DTR133. While these strains were not promoting plant growth in wild-type plants, increased plant biomass was measured in inoculated plants lacking fez, wrky70, cbp60g, pft1 and rlp30, genes mostly involved in plant immunity. These results point to an interplay between plant genotype, plant growth and rhizosphere colonization by phytobeneficial Pseudomonas spp. Some of the studied genes could become targets for plant breeding programs to improve plant-beneficial Pseudomonas rhizocompetence and biocontrol efficiency in the field.

Hate speech is the precursor to ethno-religious violence in Nigeria. In recent times, no issue has generated widespread public comment in Nigeria more than the issues of hate speech and ethno-religious violence rocking the country and its sad consequences on national integration. Though, on the issue of hate speech, the provisions of Nigeria constitution and Nigeria Electoral Act are clear but the question is where to draw the line between political statements and hate speech. Therefore, this study explored the effect of hate speech on ethno-religious violence in Nigeria. A descriptive method was adopted and data was collected via a survey of 600 respondents comprises of Traditional Leaders, Christian leaders, Muslim leaders, Leaders of civil society groups and Youth leaders in South-South, South-West, South-East, North-West, North-central and North-East geopolitical zones of Nigeria. Data collected were analyzed using correlation and linear regression analysis with the aid of Statistical Package for Social Science (SPSS) version 21. The study found that there is significant relationship between hate speech and ethno-religious violence in Nigeria. The study submits that, hate speeches in Nigeria are mostly credited to political leaders and their ethnic, religious or regional supporters. Requisite recommendations and conclusion were provided in the light of empirical and theoretical findings.

Представлены результаты экспериментального исследования тушения метанола самовспенивающейся газоаэрозоленаполненной пеной (СГП). Цель экспериментов - определение критической интенсивности подачи пены при тушении метанола в резервуаре. Обоснованы размеры модельного очага пожара. Показано, что «жесткий» способ подачи СГП для тушения метанола неэффективен. При «мягком» способе подачи пены для тушения метанола критическая интенсивность составляет 0,11 л · с · м. Получены данные о температуре факела пламени метанола и плотности теплового потока на различных расстояниях от очага пожара.
Extinguishing polar liquids in tanks such as methanol is a complex task. Its successful solution depends on the fire size, the choice of foaming agent, the way of extinguishing solution supply. When extinguishing fires in tanks it is effective to use self-foaming gas-aerosol foam (SGF). In this work there are experimentally investigated the ways of SFS supply to extinguish methanol with «hard» and «soft» methods as well as the temperature of the methanol flame plume and the intensity of its radiation intensity are measured. To generate the foam there are used units UPAT-30 and UPAT-60 (self-contained solid fuel fire extinguishing units) with a capacity of 30 and 60 liters, respectively. To produce foam there was chosen the foaming agent “Nizhny Novgorod AFFF universal”. Foam expansion was 10, and foam stability was 40 minutes. The combustible agent is a complex inhibitor of hydroformation and corrosion which contains 99 % of methyl alcohol and 1 % of the anticorrosion additive IKT1. It has been shown that the «hard» method of extinguishing agent supply to the burning methanol mirror is ineffective. The «soft» extinguishing method, when foam is supplied to the side of the tank, allows to achieve confident fire extinguishing at a critical intensity of 0.11 l · m · s. When organizing the experiments there was carried out the justification of the minimum required size (in terms of area) of the combustion base. The most suitable is the base described in the standard UL 162. The extinguishing of methanol is significantly affected not only by the size of the combustion base but also by the thickness of the tank wall. When methanol burns, the temperature of the edge of the model fire base does not exceed 350 °C, and the temperature of the torch is close to 700 °C. This explains the fact that the heat flux density close to fire is much lower than during the diesel fuel burning (in 5-7 times). This fact should be taken into account when determining the extinguishing tactics for methanol as well as safe distances from the fire seat.
Absence of rigid polyurethane foam wall ignition from electric arc welding spark

Published: March 2022

Ствие случаев зажигания пенополиуретана, которое объясняется малым временем контакта искры с поверхностью пенополиуретана t. Приводятся экспериментальные оценки фактического значения t и минимально необходимого для зажигания пенополиуретана времени контакта с искрой t.
It is known that sparks of electric arc welding, representing drops of molten metal (hereinafter - iron sparks), have a high incendiary ability. However, due to a number of reasons, there is possible a situation when electric welding does not lead to the ignition of nearby combustible materials. The identification of such causes can have an important impact on the development of a standard method for investigating the ignition power of sparks. The work investigated the possibility of spark ignition of a vertical layer of rigid polyurethane foam installed on a laboratory table (hereinafter referred to as walls). The wall was exposed to sparks from electric arc welding with a power of up to 6 kW. The distance from the source of sparking to the wall was (15 ± 3) 10 m. A separate experiment lasted several minutes until the electrode burned out, the diameter of which varied from 2 mm to 4 mm. Research results and their discussion. In none of the experiments was it possible to ignite the wall with sparks. Sparks bounced off the surface of the polyurethane foam and fell down onto the horizontal surface of the laboratory table. To explain the results, an experimental estimate was made of the time t of the interaction of the drop with polyurethane foam and the minimum time t of such interaction, leading to the ignition of the wall. The estimate t < 30 · 10 s is based on frames of video recording with a frequency of 30 s of a luminous trail of a spark, curved by a collision with a wall. The estimate t > 1 s is based on simulated droplet exposure with small scale Bunsen burner flames of varying duration. Therefore, t << t. The reason for the lack of ignition of polyurethane foam was the short contact time of the electric arc welding spark with the surface of the polyurethane foam.

PENERAPAN TEKNIK ZERO WASTE PADA PEMBUATAN BUSANA DEMI COUTURE
Authors: Putri Shella Wardhani 
Published: March 2022

The development of dynamic fashion trends greatly affects the fashion industry, where it has an impact on the increase in the amount of waste every year. Considering the increasing use of synthetic fabrics because they are considered more efficient, the waste reduction must also be carried out through efficient use of fabrics. So that it encourages designers to make changes in the design and production process so that the resulting product does not produce a lot of waste and does not even produce waste. Zero waste is a technique that can be used to reduce residual waste from production because the waste generated is less than 15%. The application of the zero waste method in Indonesia has been applied by several ready-to-wear fashion brands. Thus, the application of the zero-waste technique in this study was carried out on clothes for the sake of couture, because clothes for couture that use a lot of various design lines and silhouette shapes, make clothes for couture tend to produce more waste. This study using a qualitative method, through the collection of observational and exploratory data on a zero waste pattern. The use of this method is based on the purpose of the study, which is to show that zero waste can be the right solution in reducing fabric waste from clothing production for the sake of couture, so that the use of fabric is more optimal.

Abstract
We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where the stellar bulge component is assembled, performing axisymmetric two-dimensional radiation hydrodynamical simulations. We find that when a seed BH with M

M
⊙ is embedded in dense metal-poor gas (Z = 0.01 Z
⊙) with a density of ≳ 100 cm−3 and bulge stars with a total mass of M
⋆ ≳ 100 M
•, a massive gaseous disk feeds the BH efficiently at rates of ≳ 0.3–1 M
⊙ yr−1, and the BH mass increases nearly tenfold within ∼2 Myr. This rapid accretion phase lasts until a good fraction of the gas bounded within the bulge accretes onto the BH, although the feeding rate is regulated owing to strong outflows driven by ionizing radiation emitted from the accreting BH. The transient growing mode can be triggered for seed BHs formed in massive dark-matter halos with masses of ≳ 109

Revealing the Field Sub-subgiant Population Using a Catalog of Active Giant Stars and Gaia EDR3

Abstract
Sub-subgiant stars (SSGs) fall below the subgiant branch and/or red of the giant branch in open and globular clusters, an area of the color–magnitude diagram (CMD) not populated by standard stellar evolution tracks. One hypothesis is that SSGs result from rapid rotation in subgiants or giants due to tidal synchronization in a close binary. The strong magnetic fields generated inhibit convection, which in turn produces large starspots, radius inflation, and lower-than-expected average surface temperatures and luminosities. Here we cross-reference a catalog of active giant binaries (RS CVns) in the field with Gaia EDR3. Using the Gaia photometry and parallaxes, we precisely position the RS CVns in a CMD. We identify stars that fall below a 14 Gyr, metal-rich isochrone as candidate field SSGs. Out of a sample of 1723 RS CVn, we find 448 SSG candidates, a dramatic expansion from the 65 SSGs previously known. Most SSGs have rotation periods of 2–20 days, with the highest SSG fraction found among RS CVn with the shortest periods. The ubiquity of SSGs among this population indicates that SSGs are a normal phase in evolution for RS CVn-type systems, not rare by-products of dynamical encounters found only in dense star clusters as some have suggested. We present our catalog of 1723 active giants, including Gaia photometry and astrometry, and rotation periods from the Transiting Exoplanet Survey Satellite and International Variable Star Index (VSX). This catalog can serve as an important sample to study the impacts of magnetic fields in evolved stars.
