Feasibility Study Comparison of Pavement Designs Using Local Materials

The possibility of using local materials in the construction of structural layers of pavement is considered in the paper. The paper presents a method of technical and economic analysis, for which it is necessary to know the calculated deformation moduli of the materials being compared. Knowing the turnaround time for each of the options under consideration, it is possible, by comparing them with the payback periods, to more fully identify the technical and economic features of such options. The main criterion for the admissibility of the use of local material in the corresponding structural layer is the equal strength of pavement structures or individual structural layers made of local and imported materials. The criterion of economic feasibility of using local material can be written as an inequality. Using the principle of equivalence of systems, it is possible to replace individual structural layers of pavement, made of certain materials, with equivalent layers of stiffness from other materials, increasing or decreasing their thickness, depending on the strength characteristics of the materials themselves. The main condition for the technical feasibility of using local material has been determined on the basis of the condition of equal strength structures made from local and imported materials. A schedule for preliminary determination of the technical and economic feasibility of using local materials in the structural layers of road pavements has been built. The total value of the investment costs can be used as an additional criterion for the economic benefits of the compared options.

OPTIMIZATION OF TRUSS STRUCTURES OF THE STANDART SERIES WITH CROSS GRIDS

Представлено конструктивно-компоновочное решение стержней Y-образных и Ψ-образных очертаний в фермах с перекрестной решеткой или фермах с перекрестной решеткой и полустойками (полуподвесками), техническая новизна которого подтверждена результатами патентной экспертизы. Универсальность этого решения для ферменных конструкций обеспечивает ту эффективность, с какой оно применимо к грузовым верхним поясам, грузовым нижним поясам или грузовым верхним и нижним поясам одной и той же решетки. Повышена степень унификации типовой фермы из прокатных профилей за счет использования в верхнем поясе расчетных сечений, принятых для нижнего пояса. При этом ресурсы несущей способности разнятся между ними не более чем на полтора процента, что обеспечивает необходимую и достаточную равнопрочность обоих поясов для их более рациональной унификации. Выполнен сравнительный анализ основных результатов решения вариантного и оптимального проектирования ферменных конструкций применительно к решеткам с двойными системами полураскосов и решеткам с одинарными системами раскосов. Выявлена перспективность применения нового технического решения в составе несущих и связевых систем различных зданий и сооружений. The structural and layout solution of rods of Y-shaped and Ψ-shaped outlines in trusses with a cross lattice or trusses with a cross lattice and half-posts (half-suspensions) is presented, the technical novelty of which is confirmed by the results of patent examination. The versatility of this truss solution is as effective as it is for load tops, load bottoms, or load tops and bottoms of the same grid. The degree of unification of a typical truss of rolled sections has been increased due to the use of design sections in the upper belt adopted for the lower belt. At the same time, the resources of the bearing capacity differ between them by no more than one and a half percent, which ensures the necessary and sufficient equal strength of both belts for their more rational unification. A comparative analysis of the main results of the solution of the variant and optimal design of truss structures as applied to gratings with double systems of half-braces and gratings with single systems of braces is carried out. The prospect of using a new technical solution in the composition of bearing and communication systems of various buildings and structures has been revealed.

The defaultness hypothesis

This paper demonstrates that, when interpretation is at stake, it is only degree of defaultness that matters. Neither degree of Negation, nor degree of Affirmation, nor equal degree of Novelty, nor equal degree of Literalness/Nonliteralness, nor equal strength of Contextual support, whether linguistic or pictorial (see Heruti et al. 2019), makes a difference. Instead, it is only degree of defaultness that counts. Indeed, having established degree of defaultness of negatives and affirmatives (Experiment 1.1) and their processing cost when in isolation (Experiment 1.2), we further attested to the speed superiority of default negative interpretations, which seemed more pronounced in the Left Hemisphere rather than in the Right Hemisphere (Experiment 1.2; see Giora, Cholev et al. 2018).We then further attested to the speed superiority of these negatives, when embedded in equally strong supportive contexts. Here, we also show that default Negative Sarcasm is processed significantly faster than nondefault Affirmative Sarcasm (Experiment 2). And when embedded in equally strong sarcastically biasing contexts, both hemispheres reflect the superiority of default Negative Sarcasm over nondefault Affirmative Sarcasm (Experiments 2.1–2.2). However, given Affirmative Sarcasm’s nondefaultness, it is only nondefault Affirmative Sarcasmthat is expected and shown to rely on cueing for its derivation (Corpus-based Studies 1–2, Section 3). Still, when hedonic effects are considered (see Section 4), it is only utterances’ nondefault interpretations, whether in linguistic (Experiment 3) or pictorial contexts (Experiment 4), that are entertaining, given that they make up Optimal Innovations, while involving default interpretations in the process (see Giora et al. 2004, 2017). It is degree of defaultness, then, that affects both (i) processing speed (whether in or out of context), (ii) reliance on cueing, and (iii) hedonic effects. Finally, in Section 5, our results and conclusions are summarized.

Composite elastomeric materials filled with modified mineral fillers

In the paper, the influence of modified Angren kaolin on the properties of composite elastomeric materials based on butadiene-styrene rubber has been established that the addition of modified Angren kaolin into rubber mixtures instead of gas pedals, activators and mineral fillers causes intensive connection of sulfur with macromolecules. Adsorbed sulfur on the surface of particles of modified Angren kaolin and its uniform distribution in the composition and formation of the structure with equal force were determined. This effect shows that the modified Angren kaolin in the curing processes accelerates and activates and affects the formation of the curing grid with equal strength and helps distribution throughout the composite. It has been established that introduction of MAK into the composition of elastomers more than 50 wt. % per 100 wt. % of rubber changes technological and technical properties of composite elastomeric materials. The application of modified Angren kaolin instead of the gas pedal, activator of vulcanization and mineral filler in composite elastomeric materials allows making rubber goods of various purposes.

Rhythm in the 2nd part of Wasyl Barka’s book ‘Ocean’ (mixed trochee)

The article is dedicated the verse rhythm in the second part of the book “Ocean” by the Ukrainian poet Vasyl Barka (1979). The rhythm of the first part (iambic) was investigated in our previous article. The meter of the second part of the book is a mixed trochee, the scheme of which is 5454. The stresses in the poetic lines were counted and the rhythm profiles of the trochaic tetrameter and the trochaic pentameter were plotted. The rhythm diagram method developed by Taranovsky, Gasparov (for Russian verse) was used to compare Barka’s verses with Ukrainian and Russian verses. To illustrate the trends in Ukrainian verse, our calculations of the verse of Stus and Andrukhovich were also used. The results of the research showed that the character of Barka’s rhythm is unique; it has no correspondence either in Ukrainian or in Russian verses. In the rhythm of Barka’s poem, ‘the law of regressive dissimilation’, discovered by Taranovsky and extrapolated to the Ukrainian verse by Kostenko, does not work. That is, there is no alternation of strong and weak foot. Barka in trochee avoids full-accented lines, which are commonly used by Ukrainian and Russian poets. The set of rhythmic forms of verse differs from other poets. The drawing of the diagrams is also different. For a trochaic pentameter, this is a “bucket”, with strong 2nd and 5th feet and weak 3rd and 4th feet. And for a trochaic tetrameter, this is an almost equal strength of the first three feet and a strong last foot. A rhythm, approximately similar to that of Barka, was revealed only in Goethe’s verse for a trochaic pentameter and in Schiller’s verse for a trochaic tetrameter (according to Taranovsky). Given the unique nature of the iambic rhythm and rhyme in Barka’s verse, we consider it promising to search for the factors that determined Barka’s poetics.
