The system of engine in a car is one of the magnetohydrodynamic (MHD) implementations. This system applies the basic concept of MHD, which is fluid motion that can conduct electric current because of a magnetic field. Several researchers therefore commenced to develop these ideas by observing the characteristics of the numerical simulation solutions. Because of the significance of this research, we are interested in assessing the effect of forced convection on MHD fluid flow, especially nano-fluids, when passing over a magnetic object. We therefore consider the MHD analysis of nano-fluids through sliced magnetic spheres that are induced by mixed convection problem using a mathematical model. This mathematical model is developed from the continuity equation, the momentum equation and the energy equation. The model is then elucidated numerically by means of the finite difference method with the Keller-Box scheme and MATLAB software. Furthermore, within numerical simulations investigated the effects of magnetic parameters (M), slice angle parameters (θs), and volume fraction of nano-fluid (X) towards fluid velocity and temperature. The numerical solutions express that when the magnetic parameter (M) rises, the velocity of the nano-fluid drops and the temperature of the nanofluid growths. When the cut angle parameter (θs) enlarges, the velocity of the nano-fluid enhances and the temperature of the nano-fluid lessens. When the volume fraction of nanofluid (X) expansions, the velocity of the nano-fluid falls and the temperature of the nanofluid rises.

In this study, mixed cultures of brown-rot fungus Gloeophyllum trabeum and filamentous fungus Trichoderma viride in decolorizing Methylene Blue (MB) has been investigated. T. viride culture was mixed with G. trabeum culture and then MB was added into the media to achieve final concentration 95.24 mg/L. The results showed single culture of G. trabeum and T. viride can decolorize MB only 31.50% and 53.89%, respectively. While decolorization of MB by mixed cultures of G. trabeum and T. viride reached to 74.72% in a liquid medium of potato dextrose broth (PDB) for 7 days. The results showed mixed cultures had the highest ability to decolorize MB among those variations. Based on the LC- TOF/MS analysis, the peak of MB in mixed cultures treatment had a lower intensity compared to the peak of MB in abiotic control. The metabolites from MB biodecolorization by G. trabeum were C8H10N2SO5, C6H8N2SO3, C16H20N3SO, C6H7NSO3, and C12H10N3S, while the metabolites from MB biodecolorization of T. viride were C16H23N3O3S, C22H26NO2S, and C31H48N3S. On the other hand, the metabolites from the MB biodecolorization by mixed cultures were C16H23N3O3S, C31H48N3S, C31H47N2OS and C17H20N2S. This study indicated that mixed cultures of brown-rot fungus G. trabeum and filamentous fungus T. viride was effective to decolorize MB dye.

Tsinghua University-Ma Huateng Telescopes for Survey (TMTS) aims to detect fast-evolving transients in the Universe, which has led to the discovery of thousands of short-period variables and eclipsing binaries since 2020. In this paper, we present the observed properties of 125 flare stars identified by TMTS within the first two years, with an attempt to constrain their eruption physics. As expected, most of these flares were recorded in late-type red stars with GBP − GRP > 2.0 mag;however, the flares associated with bluer stars tend to be on average more energetic and have broader profiles. The peak flux (Fpeak) of the flare is found to depend strongly on the equivalent duration (ED) of the energy release, i.e., Fpeak ∝ ED0.72±0.04, which is consistent with results derived from the Kepler and Evryscope samples. This relation is likely related to the magnetic loop emission, while, for the more popular non-thermal electron heating model, a specific time evolution may be required to generate this relation. We notice that flares produced by hotter stars have a flatter Fpeak ∝ ED relation compared to that from cooler stars. This is related to the statistical discrepancy in light-curve shape of flare events with different colors. In spectra from LAMOST, we find that flare stars have apparently stronger Hα emission than inactive stars, especially at the low temperature end, suggesting that chromospheric activity plays an important role in producing flares. On the other hand, the subclass with frequent flares is found to show Hα emission of similar strength in its spectra to that recorded with only a single flare but similar effective temperature, implying that the chromospheric activity may not be the only trigger for eruptions.

This study reported methylene blue (MB) dye decolorization by using mixed consortium culture, brown-rot fungus (BRF) Gloeophyllum trabeum which is known as degradative fungus with bacterium Bacillus subtilis addition. B. subtilis were added into G. trabeum cultures at variation 2, 4, 6, 8, and 10 mL and incubated statically (1 mL = 9.47 × 108 CFU). All of mixed cultures had ability to decolorize MB (100 mg/L) in potato dextrose broth (PDB) medium during incubation process at 30 °C for 7 days. The addition of 10 mL B. subtilis in fungus culture showed the highest of MB decolorized, approximately 82%, while using G. trabeum culture only was approximately 11%. The metabolites of MB biodecolorization were identified and characterized by LC-TOF/MS, which were N-(7-(dimethylamino)-1-hydroxy-3H-phenothiazin-3-ylidene)-N-methylmethanaminium; 2-amino-5-(dimethylamino)-3-((3-(dimethylamino) phenyl) sulfinyl) phenol; and N-7-(7-(dimethylamino)-1,4,6,9-tetrahydroxy-3H-phenothiazin-3-ylidene)-N-methylmethanaminium. Those results could indicate that the mixed consortium culture of BRF G. trabeum with B. subtilis addition were efficient for dye wastewater treatment.

Chemical reactions can be understood as transformations of multigraphs (molecules) that preserve vertex labels (atoms) and degrees (sums of bonding and non-bonding electrons), thereby implying the atom-atom map of a reaction. The corresponding reaction mechanism is often described by an electron pushing diagram that explains the transformation by consecutive local relocations of invidudal edges (electron pairs). Here, we show that every degree-preserving map between multigraphs, and thus every atom-atom map, can be generated by cyclic electron pushing. Moreover, it is always possible to decompose such an explanation into electron pushing diagrams involving only four electron pairs. This in turn implies that every reaction can be decomposed into a sequence of elementary reactions that involve at most two educt molecules and two product molecules. Hence, the requirement of a mechanistic explantion in terms of electron pushing and small imaginary transition states does not impose a combinatorial constraint on the feasibility of hypothetical chemical *** Codes 05C92, 92E10 Copyright © 2023, The Authors.

Field service planning and scheduling research focuses on providing solutions to scenarios in which personnel travel between multiple locations carrying out different tasks specific to the field where they work. However, studying"what-if" activities in these scenarios is challenging for researchers, who have to deal with the impact on client service agreements, preferences of technicians when tasks are assigned, or unexpected faulty units. Therefore, simulation techniques are widely used to experiment and understand some critical aspects of workforce scheduling. Unfortunately, to mimic reality a high number of parameters are required within simulation models, raising scalability issues when the number of technicians, activities, and units increase over certain limits. This work1 presents a flexible simulation model to address field service planning and scheduling in large scale scenarios. The evaluation proves that the model executes in reasonable time for environments that consist of hundreds of thousands of locations in which technicians must perform diverse numbers of activities. © 2019 EUROSIS-ETI.

It is one of the most challenging problems in applied mathematics to approximatively solve high-dimensional partial differential equations (PDEs). Recently, several deep learning-based approximation algorithms for attacking this problem have been proposed and tested numerically on a number of examples of high-dimensional PDEs. This has given rise to a lively field of research in which deep learning-based methods and related Monte Carlo methods are applied to the approximation of high-dimensional PDEs. In this article we offer an introduction to this field of research by revisiting selected mathematical results related to deep learning approximation methods for PDEs and reviewing the main ideas of their proofs. We also provide a short overview of the recent literature in this area of *** Codes 65M99 (Primary), 35-02, 65-02, 68T07 (Secondary) Copyright © 2020, The Authors. All rights reserved.
