    In this work, the optimal combinations of Al – Si in cast iron for cast parts for machine-building purposes were determined with the aim of subsequent selection of rational modes of modification and alloying, and the possibility of their implementation under industrial smelting conditions was checked. The graphical dependence Si=f (Al) is obtained, which is a set of optimal combinations of the content of Al and Si in cast iron, providing the maximum ultimate tensile strength UTS≈245 ... 334 MPa. The technological audit of the results of serial industrial smelting included the analysis of actual indicators, the calculation of sample distribution functions (mathematical expectation and dispersion) of the Al and Si content in the alloy, as well as the UTS value. The correspondence of the indicators of the content of Al and Si and the value of σ to the optimal values was assessed by testing the statistical hypotheses: H: M(Al)=Alopt, M(Si)=Siopt, M(σĐČ)=σĐČopt.On the basis of the obtained results of the assessment of statistical characteristics and verification of hypotheses, it was established that at the chosen significance level α=0.05, the technological process of smelting satisfies the requirements of optimality in terms of the Si content, but in terms of the Al content, the technological process does not meet the requirements of optimality. The proposed procedure for choosing the optimal combinations of Al and Si makes it possible to choose the amount of correcting additives depending on the actual indicators of the chemical composition during the smelting process. To do this, it is necessary to assess the closeness of the actual composition to the optimal curve Si=f(Al) and choose the one that most satisfies the criteria of rationality. The latter can be the cost of ferroalloys, through which Al and Si are introduce

    Two graphene monolayers that are oppositely charged and placed close to each other are considered. Taking into account valley and spin degeneracy of electrons we analyze the symmetry of the excitonic insulator states in such a system and build a phase diagram that takes into account the effect of the symmetry breaking due to the external in-plane magnetic field and the carrier density imbalance between the layers.Comment: 12 pages, 6 figures, 1 tabl

    The research has been conducted to determine the safe residence time for people in a room where the composition of the gas environment has deteriorated due to fire. Carbon monoxide, which is produced by fire, has been found to be lethal for human life and health. Determination of safe time was made based on the study of the composition and amount of fire load in premises and buildings, physical and chemical properties of carbon monoxide, and its effect on the human body. The graphical dependences of the concentration of carbon monoxide in a room, as a function of time, were obtained for eight variants. The results allow authors to determine the possible residence time of a person in a building during a fire before the lethal concentration of carbon monoxide occurs. Studies made it possible to determine the safe residence time of people in a building on fire in a calculated way and to compare it with the normative indicators of the onset of lethal concentration of carbon monoxide in the air. The results obtained determine the safe time during which a person can escape from the building on fire.IstraĆŸivanje je provedeno kako bi se utvrdilo koliko dugo ljudi mogu boraviti u prostoriji u kojoj je kakvoća zraka smanjena zbog poĆŸara. Ugljični monoksid, proizvod poĆŸara, jest smrtonosan i opasan za zdravlje. Sigurno vrijeme boravka utvrđeno je na temelju ispitivanja sastava i količine poĆŸarnog opterećenja u prostorijama i zgradama, fizikalnih i kemijskih svojstava ugljičnog monoksida i njegova djelovanja na ljudsko tijelo. Grafički je prikazana ovisnost koncentracije ugljičnog monoksida u prostoriji kao funkcije vremena, i to za osam varijanti. Rezultati omogućuju da se utvrdi moguće vrijeme boravka u zgradi tijekom poĆŸara prije nego dođe do smrtonosne koncentracije ugljičnog monoksida. Ispitivanjem je izračunato vrijeme sigurnog boravka u poĆŸarom zahvaćenoj zgradi te je moguća usporedba s normativnim pokazateljima dostizanja smrtonosne koncentracije ugljičnog dioksida u zraku. Rezultati sluĆŸe za utvrđivanje sigurnog vremena za bijeg ljudi iz poĆŸarom zahvaćene zgrade

    Thermophysical properties of various substances and mixtures were studied by the non-destructive method. It is proposed to determine the thermal conductivity of substances and mixtures by the thermistor direct heating method.The device was created for measuring the thermal conductivity of various substances and mixtures, the operation of which is based on measuring the temperature of thermistor heating in the test substance. The nonlinear nature of the obtained thermistor heating dependence is taken into account.Based on the studies, the possibility of determining the composition of the mixture by its thermal conductivity coefficient is shown. The results of experimental studies with reference liquids, solutions of sugar, glycerin and alcohol in water are presented. The results of the studies to determine the thermophysical properties (TPP) of biological substances (human blood and blood plasma, egg white and yolk and others), some vegetables using the method of thermistor direct heating in the temperature range from +25 °Х to +40 °Х are given. It is substantiated that when studying the TPP of substances by thermistor direct heating, it is possible to determine the composition of mixtures by their thermal conductivity, but it is necessary to take into account individual properties of the studied liquids. Recommendations are given for studying the TPP of substances and determining the composition of mixtures by their thermal conductivity, taking into account individual properties of the studied substances.Using the proposed method of thermistor direct heating to determine a mixture of solutions, biological materials and food products allows analyzing the composition of nanosubstances, obtaining reliable data on the degree of allergic reaction, and in determining the composition of food products – taking into account the data obtained when developing refrigeration equipment and extending the shelf life of products while maintaining their useful qualities.Đ˜ŃŃĐ»Đ”ĐŽĐŸĐČĐ°ĐœŃ‹ Ń‚Đ”ĐżĐ»ĐŸŃ„ĐžĐ·ĐžŃ‡Đ”ŃĐșОД сĐČĐŸĐčстĐČĐ° Ń€Đ°Đ·Đ»ĐžŃ‡ĐœŃ‹Ń… ĐČДщДстĐČ Đž ŃĐŒĐ”ŃĐ”Đč ĐœĐ”Ń€Đ°Đ·Ń€ŃƒŃˆĐ°ŃŽŃ‰ĐžĐŒ ĐŒĐ”Ń‚ĐŸĐŽĐŸĐŒ.

The results of the studies to determine the thermophysical properties (TPP) of biological substances (human blood and blood plasma, egg white and yolk and others), some vegetables using the method of thermistor direct heating in the temperature range from +25 °Х to +40 °Х are given. It is substantiated that when studying the TPP of substances by thermistor direct heating, it is possible to determine the composition of mixtures by their thermal conductivity, but it is necessary to take into account individual properties of the studied liquids. Recommendations are given for studying the TPP of substances and determining the composition of mixtures by their thermal conductivity, taking into account individual properties of the studied substances.Using the proposed method of thermistor direct heating to determine a mixture of solutions, biological materials and food products allows analyzing the composition of nanosubstances, obtaining reliable data on the degree of allergic reaction, and in determining the composition of food products – taking into account the data obtained when developing refrigeration equipment and extending the shelf life of products while maintaining their useful qualities.Đ˜ŃŃĐ»Đ”ĐŽĐŸĐČĐ°ĐœŃ‹ Ń‚Đ”ĐżĐ»ĐŸŃ„ĐžĐ·ĐžŃ‡Đ”ŃĐșОД сĐČĐŸĐčстĐČĐ° Ń€Đ°Đ·Đ»ĐžŃ‡ĐœŃ‹Ń… ĐČДщДстĐČ Đž ŃĐŒĐ”ŃĐ”Đč ĐœĐ”Ń€Đ°Đ·Ń€ŃƒŃˆĐ°ŃŽŃ‰ĐžĐŒ ĐŒĐ”Ń‚ĐŸĐŽĐŸĐŒ.

    Core Proteome of the Minimal Cell: Comparative Proteomics of Three Mollicute Species

    Get PDF
    Mollicutes (mycoplasmas) have been recognized as highly evolved prokaryotes with an extremely small genome size and very limited coding capacity. Thus, they may serve as a model of a ‘minimal cell’: a cell with the lowest possible number of genes yet capable of autonomous self-replication. We present the results of a comparative analysis of proteomes of three mycoplasma species: A. laidlawii, M. gallisepticum, and M. mobile. The core proteome components found in the three mycoplasma species are involved in fundamental cellular processes which are necessary for the free living of cells. They include replication, transcription, translation, and minimal metabolism. The members of the proteome core seem to be tightly interconnected with a number of interactions forming core interactome whether or not additional species-specific proteins are located on the periphery. We also obtained a genome core of the respective organisms and compared it with the proteome core. It was found that the genome core encodes 73 more proteins than the proteome core. Apart of proteins which may not be identified due to technical limitations, there are 24 proteins that seem to not be expressed under the optimal conditions

    Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

    Get PDF
    The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

    Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

    Get PDF
    This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat

    Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

    Get PDF
    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (Ό̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ÂŻ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ÂŻ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),Ό̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| &lt; 0.03 at 95% confidence level.
