Hyteroatoms Si, P, S as possible factors for the formation of the structure of pyrolyzed carbon materials

The aim of the study was to investigate the effect of heteroatoms on the deformation of graphene, as well as on the formation of the Stone-Wallace defect. To date, research on processes involving nanocarbon materials is relevant. In particular, in the formation of fullerenes, nanoonions and a number of other carbon nanoforms, the five-membered carbon cycles (pentactagonis) of the hepatogenesis (pentactagon) play the most important role in the curvature of initially flat graphene sheets and the formation of fullerene-like structures in the form of closed, skeletal, macromolecular formations. It should be noted, however, that the Pentagon is not the only factor in distorting the flat structure of graphene sheets in layered carbon materials. Some other defects of the carbon lattice (in particular, seven-membered carbon cycles and heteroatoms of a number of nonmetals with covalent radii exceeding the radius of the carbon atom) may play a similar role to one degree or another. These heteroatoms (primarily Si, P, S) are usually part of the precursors of mineral or vegetable origin and can be embedded in the carbon lattice in the process of coal production. Stone-Wallace there is their mutual compensation and preservation of a flat structure. The calculations were performed using quantum chemical modeling of doped nanographs in clusters of different size, composition and morphology, using the theory of density functional (DFT) with exchange-correlation functional B3LYP, based on the extended valence-split basis 6-31G (d) with full optimism clusters using the Firefly software package. It has been found that heteroatoms of non-metals with covalent radii exceeding the radius of the C atom, which are usually present in the precursors of mineral or vegetable origin used to produce pyrolyzed carbon materials, can play a significant role in energy. a number of nanoforms of carbon, activated carbon and other pyrolyzed nanostructured carbon materials.

The effect of varietal traits of durum wheat on the technological and baking qualities of flour when mixed with bread wheat

The development of bakery industry is possible due to the use of such non-traditional raw materials as durum wheat. The purpose of the current study was to estimate the effect of varietal traits of durum wheat when mixed with bread wheat according to the results of rheological parameters of dough, technological and bakery estimation of flour. There have been studied technological indicators of grain, rheological and physical parameters of dough, general bakery estimation. There has been established that the high gas-forming ability of durum wheat allows it to be used (30%) as bread wheat improver during baking. However, the positive effect was present not in all years of the study. There has been estimated an improvement effect due to mutual compensation of the missing components and complementarity of the bread and durum wheat varieties. There was found that in 2008, 2010 there was practically no improvement effect when durum wheat flour was added to the mixture in a ratio of 30:70%. There was established that in 2015 the maximum bread volume of 930 cm3 and a good bakery estimation (flat surface, oval shape, golden brown crust, as well as fine thin-walled porosity with elastic light crumb) were obtained by adding bread wheat varieties to durum wheat varieties, which during the year of the study there was formed weak grain (dilute of dough was 110 u.f.; valorigraphic number was 46 u.v.). In 2020, the varieties used in the mixtures of both spring bread and durum wheat were of high quality, and bakery estimation gave excellent indicators both in the control (the variety ‘Tulaykovskaya 108’ with 1300 cm3) and in the mixtures with 1140–1255 cm3; the appearance of bread and crumb in almost all variants had an excellent mark. The largest volume of bread, 1255 cm3, was obtained when the durum wheat variety ‘Bezenchukskaya Niva’ was added to the mixture. Adding durum wheat flour to the mixture in an amount of 30:70% when baking bread reduced its staleness by 6.5% relative to the control (bread wheat); bread remains fresh for a long time with an elastic, quickly regenerated crumb.

Study on the streamflow compensation characteristics of reservoirs in Luanhe River Basin based on Copula function

With the rapid development of economy and society, the contradiction between supply and demand of water resources is increasing. Efficient utilization and allocation of limited water resources are one of the main means to solve the above contradictions. In this paper, the multidimensional joint distribution of natural streamflow series in reservoirs is constructed by introducing the mixed Copula function, and the probability of wet and dry encounters between natural streamflow is analyzed. Luan River is located in the northeastern part of Hebei Province, China, taking the group of Panjiakou Reservoir, Douhe Reservoir and Yuqiao Reservoir in the downstream of Luan River Basin as an example, the probabilities of synchronous and asynchronous abundance and depletion of inflow from the reservoirs are calculated. The results show that the probability of natural streamflow series between reservoirs is 61.14% for wetness and dryness asynchronous, which has certain mutual compensation ability. Therefore, it is necessary to minimize the risk of water supply security in Tianjin, Tangshan and other cities, and strengthen the optimal joint water supply scheduling of reservoirs. The research results are reasonable and reliable, which can provide reference for water supply operation of other basins.

Modeling of the electromagnetic field of radiating aperture

The article is devoted to the issues of numerical calculation of the characteristics of the electromagnetic field of radiating apertures. Тhe radiating aperture is a universal electrodynamic model used in the analysis of a special class of antennas, in particular, mirror and horn antennas, in the study of diffraction phenomena, in the planning of radio wave propagation paths, and when solving problems of wireless transmission of electric energy at a distance. The structure of the electromagnetic field of a radiating aperture in the intermediate and far zones is of the greatest interest according to the needs of practice. However, the theoretical solutions of these problems are usually difficult to obtain, except for some special cases related to the far zone. This leads to the development of appropriate computational models. This paper is aimed at generalization and systematization of experience in developing software for the simulation of electromagnetic field characteristics of radiating apertures in the intermediate and far zones. This paper considers an approach to developing a computational model of a radiating aperture that may be used to calculate the characteristics of electromagnetic field in the intermediate and far zones. Examples of results obtained for circular and ring apertures describing the structure of their electromagnetic field are given. Examples of flight diagrams of a circular aperture are given. The effect of “searchlight” localization of the electromagnetic field in the intermediate zone of a circular emitting aperture is demonstrated. The effect of mutual compensation of neighbouring Fresnel zones using the circular emitting aperture model is demonstrated. A program was developed for calculating the characteristics of the electromagnetic field of radiating holes in the intermediate and far zones. The results can also be used as illustration material for teaching the academic disciplines “Electrodynamics and radio wave propagation” and “Microwave devices and antennas”.

The Transformation Problem of Values into Prices of Production: Marx Errors or an Inattentive Reading of 'Capital'?

The author presents the results of the discovery in Marx's works of the disparate elements of the theory of the original transformation of value into prices and the establishment of the general rate of profit. These results show:(a) Marx's tables in Chapter 9 of Volume III of Capital do not represent the usual interrelated branches of the economy, but particular spheres of production, exempt from the double-counting of profits and wages, and producing only final commodities. The total value of these commodities is equal to the net social product.(b) Marx carried out the original transformation of values into prices under the condition that wages remain unchanged. As a result, the first (chief) macroeconomic equality is fulfilled—the sum of the production prices for all net social products must be equal to the sum of its values. Also is fulfilled the second macroeconomic equality—the sum of profits of all sectors forming separate spheres of production must be equal to the sum of surplus values.(c) Marx assumed that the original transformation takes place in two stages: in the first stage, average rates of profit are formed in separate spheres of production, comprising two sectors of production: A and B. Sector A produced of constant capital for the sphere's own need. Sector B releases the final product for an exchange with other particular spheres. In the second stage, is established the general rate of profit in sectors B. A property of the original conversion is some change in the level of real wages, especially noticeable when using numerical models with a few spheres of commodity production. Therefore, Marx introduces the hypothesis of mutual compensation of positive and negative deviations of prices from the values of commodities. The hypothesis is fully confirmed under the conditions of the law of large numbers.(d) Marx also explains that non-equilibrium original prices of production, in which demand and supply of final goods do not coincide, can be transformed into equilibrium prices of production. For this to happen, corresponding changes in monetary wages, prices of constant capital, and the general rate of profit are necessary. However, the attainment of equilibrium prices was regarded by Marx as a secondary issue. At equilibrium prices, only the first (chief) macroeconomic equality is fulfilled.The author in developing alternative methods of transforming value into original and equilibrium prices of production uses all of the above elements of the theory of transformation of values into production prices. First, he restores the double counting of profits and wages in Marx's table. Second, he applies an iterative procedure of sequentially establishing the average and general rate of profit in the sectors and spheres of commodity production.The paper proposes new iterative calculation algorithms in the Excel program for the original and equilibrium transformation of values into production prices. The author tested the algorithms using the Wolfram Mathematica software. He also developed a method for converting the equilibrium production prices of goods back to their initial absolute values. This method refutes the well-known “eraser algorithm” by P. Samuelson. Ultimately, the author argues that Marx does not have the errors of transformation that his critics have attributed to him for so long.

Atomistic mechanisms for frictional energy dissipation during continuous sliding

From a first-principles-based analysis, atomistic mechanisms of frictional energy dissipation are established. For a rigid object moving continuously in the periodic surface potential landscape of a solid that has vibrational degrees of freedom, they can be viewed as (i) the continuous pumping of energy into the resonant modes, if these exist, and (ii) the destructive interference of the force contributions introduced by all excited phonon modes. We report a surprising, mutual compensation between these two basic effects, which leads to very regular oscillations of the dissipative force, with a period determined by half the period of the solid lattice, while the mean friction force experienced by the sliding object hardly depends on time and varies in a straightforward manner with the sliding velocity. These mechanisms act already in a purely dynamic system that includes independent, non-interacting phonon modes, and they manifest irreversibility as a kind of "dynamical stochastization". In contrast to wide-spread views, we show that transformation of mechanical energy into heat, that always takes place in real systems due to the coupling between phonon modes, can play only a minor role in the appearance of friction, if any. This insight into the microscopic mechanisms of energy dissipation opens a new, direct way towards true control over friction.

ASDP Ferry (PERSERO) is in accordance with the provisions of the national land law in terms of the transfer of rights, which has been carried out according to land acquisition procedures through socialization and deliberation with land rights holders, but because the land is still in dispute, it is in accordance with the provisions of Law No. 2 of 2012, PT ASDP Fery Persero made a request for payment through consignment / deposit money. The consignment / deposit of money by PT ASDP Fery Persero for the construction of the Hunimua Ferry Crossing Port in Liang State, Central Maluku Regency has legal consequences for the transfer of land rights which are transferred from land rights holders to PT ASDP Fery Persero so that the construction activities of the Hunimua Ferry Port expansion can be carried out.

BETA- AND GAMMA-SYNUCLEINS MODULATE SYNAPTIC VESICLE-BINDING OF ALPHA-SYNUCLEIN

SUMMARYα-Synuclein (αSyn), β-synuclein (βSyn), and γ-synuclein (γSyn) are abundantly expressed in the vertebrate nervous system. αSyn functions in neurotransmitter release via binding to and clustering synaptic vesicles and chaperoning of SNARE-complex assembly. The functions of βSyn and γSyn are unknown. Functional redundancy of the three synucleins and mutual compensation when one synuclein is deleted have been proposed, but with conflicting evidence. Here, we demonstrate that βSyn and γSyn have a reduced affinity towards membranes compared to αSyn, and that direct interaction of βSyn or γSyn with αSyn results in reduced membrane binding of αSyn. Our data suggest that all three synucleins affect synapse function, but only αSyn mediates the downstream function of vesicle clustering and SNARE-complex assembly, while βSyn and γSyn modulate the activity of αSyn through regulating its binding to synaptic vesicles.

Balancing quarantine and self-distancing measures in adaptive epidemic networks

We study the relative importance of two key control measures for epidemic spreading: endogenous social self-distancing and exogenous imposed quarantine. We use the framework of adaptive networks, moment-closure, and ordinary differential equations (ODEs) to introduce several novel models based upon susceptible-infected-recovered (SIR) dynamics. First, we compare computationally expensive, adaptive network simulations with their corresponding computationally highly efficient ODE equivalents and find excellent agreement. Second, we discover that there exists a relatively simple critical curve in parameter space for the epidemic threshold, which strongly suggests that there is a mutual compensation effect between the two mitigation strategies: as long as social distancing and quarantine measures are both sufficiently strong, large outbreaks are prevented. Third, we study the total number of infected and the maximum peak during large outbreaks using a combination of analytical estimates and numerical simulations. Also for large outbreaks we find a similar compensation effect as for the epidemic threshold. This suggests that if there is little incentive for social distancing within a population, drastic quarantining is required, and vice versa. Both pure scenarios are unrealistic in practice. Our models show that only a combination of measures is likely to succeed to control epidemic spreading. Fourth, we analytically compute an upper bound for the total number of infected on adaptive networks, using integral estimates in combination with the moment-closure approximation on the level of an observable. This is a methodological innovation. Our method allows us to elegantly and quickly check and cross-validate various conjectures about the relevance of different network control measures. In this sense it becomes possible to adapt models rapidly to new epidemic challenges such as the recent COVID-19 pandemic.
