Small Prose Constants by F. Sologub

The question of constants in the short prose of F. Sologub is considered. Special attention is paid to the iconic cycle of stories in the work of the author. The results of the analysis of motives, chronotope, recurring elements of the plot and the system of characters in the cycles “The Sting of Death” and “Unkind Lady” are presented. It is shown with the help of comparative and intertextual methods that in the stories of the cycles the constant binary opposition of a meaningless, cruel life and a consoling death is embodied, the hero’s dreams of death determine the meaninglessness of being. It has been proved that time and partly space in the stories of the cycles are binary organized, but this is not the duality of this and other worlds: the hero does not go beyond the boundaries of this world, but the time and space of this world change under the influence of the altered consciousness of the hero. The author dwells on the analysis of motivational complexes that also represent oppositions, which allows us to conclude that there are constant signs of Sologub’s artistic world. The novelty of the research lies in the fact that modern comprehension of classical works using a new technique made it possible to see the internal complex interconnection of texts, to find explicit and implicit signs of interaction between cycles.

Numerical and experimental investigations on the flow and noise characteristics in a centrifugal fan with step tongue volutes

This paper presents numerical and experimental investigations on the flow and noise characteristics in a forward multi-blade centrifugal fan with step tongue volutes. Numerical simulations are performed by large eddy simulation, and the experiments are conducted to test the effects of the cut-off arrangements on the noise characteristics of the fan. The objective of this work is to explore the effect of the double-stepped tongue and single-stepped tongue on the internal complex flow and the noise generation within the fan. The comparison of the results of numerical calculation demonstrates that the internal complex flow of centrifugal fan can be controlled by the stepped tongue, the flow loss in meridian plane for the double-stepped tongue (HLHL, L stands for low and H for high) model is obviously lower than that of the original model, the Q-criterion value of HLHL model is lower than that of the original model, and the noise of the HLHL model produces an obvious decrease of 1.90 dB compared to that of the reference model. The comparison of the test results further shows that the HLHL model produces a decrease about 1.97 dB compared to that of the reference model, which mainly indicates the double-stepped tongue HLHL model more effectively controls the tonal noise comparing to the single-stepped tongue (HL) model. Meanwhile, the stepped arrangements possess comparable performance characteristics to the reference model. The double-stepped tongue HLHL model makes a positive contribution to the pressure rise of the centrifugal fan.

Extentions of neutrosophic cubic sets via complex fuzzy sets with application

In this paper, we propose that the complex neutrosophic cubic set (internal and external) show, which is a blend of complex fuzzy sets, neutrosophic sets, and cubic sets. We characterize a few set theoretic activities of internal complex neutrosophic sets, for example, union, intersection and complement, and a while later the operational principles. A few ideas identified with the structure of this model are clarified. We present some accumulation administrators and talk about some basic leadership issue with genuine model.

Deeply subducted continental fragments: II. Insight from petrochronology in the central Sesia Zone (Western Italian Alps)

Continental granulite terrains subducted to mantle depths commonly show only partial and localized eclogitization. The Sesia Zone (NW Italy) is exceptional as eclogitic micaschists predominate in large parts of this terrane, and Alpine high-pressure (HP) assemblages almost completely replaced the Permian granulite protoliths. This study documents when and at what conditions this extensive HP-equilibration took place. Results constrain the main stages of mineral growth and deformation, associated with fluid influx that occured during continental subduction. Our study comprises both main complexes of the Sesia terrane and covers some of the recently recognized tectonic subunits involved in its assembly, hence our data constrain the HP-tectonics that formed the Sesia Zone. In the Internal Complex (IC), pulses of fluid percolated at eclogite facies conditions, between 77 and 55 Ma with the HP-conditions reaching ~ 2 GPa and 600–670 °C. By contrast the External Complex (EC) records a lower pressure peak of ~ 0.8 GPa for 500 °C, at ~ 63 Ma. The juxtaposition of the two complexes occurred during exhumation, at ~ 0.8 GPa and 350 °C; the timing is constrained between 46 and 38 Ma. Mean vertical exhumation velocities are constrained between 0.9 and 5.1 mm/year for the IC, up to its juxtaposition with the EC. Exhumation to the surface occurred before 32 Ma, as constrained by the overlying Biella Volcanic Suite, at a mean vertical velocity between 1.6 and 4 mm/year. These findings constrain the processes responsible for the exhumation and assembly of high pressure continental units.

Study on Split-Open Loading in V-Shaped Components Forming Process

Basised on the study of effect with different loading ways on v-shaped components forming process. Put forward a kind of split open control loading technology aiming at forming this kind of components. Studied the effect of key process parameters of split open loading on the quality of finish forging, the key process parameters scopeis given by avoid the finish forging defects. Using shunt split open loading process forming v-shaped components, make internal complex mold cavity filled full, improved the deformation uniformity, reduced the forming load.
