Energy transfers in small-scale and large-scale dynamos
No full textWe study energy transfers during magnetic energy growth in small-scale and large-scale dynamos. We perform direct numerical simulations for magnetic Prandtl number Pm =20 and 0.2 in a periodic box on 1024^3 grid. Energy fluxes and shell-to-shell energy transfers indicate that in small-scale dynamo for Pm =20, the magnetic energy growth takes place due to a non-local energy transfer from large-scale velocity field to small-scale magnetic field. On the other hand, in large-scale dynamo for Pm =0.2, local energy transfers from large-scale velocity field to large-scale magnetic field takes place

No full textLAGOS-AND-PM is an author name disambiguation (AND) dataset for the PubMed database, containing several versions, and they are built based on the ORCID database and the PubMed literature database.
Note that we have previously created another dataset named LAGOS-AND, which refers to a series of AND datasets created for the MAG/OpenAlex database
Higher-order Network Analysis of Fine Particulate Matter (PM 2.5) Transport in China at City Level
No full textabstract: Specification of PM[subscript 2.5] transmission characteristics is important for pollution control and policymaking. We apply higher-order organization of complex networks to identify major potential PM[subscript 2.5] contributors and PM[subscript 2.5] transport pathways of a network of 189 cities in China. The network we create in this paper consists of major cities in China and contains information on meteorological conditions of wind speed and wind direction, data on geographic distance, mountains, and PM[subscript 2.5] concentrations. We aim to reveal PM[subscript 2.5] mobility between cities in China. Two major conclusions are revealed through motif analysis of complex networks. First, major potential PM[subscript 2.5] pollution contributors are identified for each cluster by one motif, which reflects movements from source to target. Second, transport pathways of PM[subscript 2.5] are revealed by another motif, which reflects transmission routes. To our knowledge, this is the first work to apply higher-order network analysis to study PM[subscript 2.5] transport.The final version of this article, as published in Scientific Reports, can be viewed online at: http://www.nature.com/articles/s41598-017-13614-
Evaluation of effects of geometrical parameters on density distribution in compaction of PM gears
No full textThe usage of powder metallurgy (PM) for manufacturing of transmission components in automotive industries has been studied by many researchers. PM components have become of interest in recent years due to advancements in post processing possibilities such as hot isostatic pressing (HIP). Still in many of the forming process routes for making components from PM materials, the compaction of the powder into green component is the first step. Compaction is required to put the powder into the near net shape of the desired component and it causes a density gradient in the body of the green component. Basically the friction between powder particles and between the powder particles and die walls are the well-known roots for such density gradients in the compacted component. Looking at forming of PM gears, the gradient in density is one of the most important roots of problems in the processing of PM gears as well. That is because making a gear with full density and no pores will be very costly if large density gradients exist in the green component. The purpose of this study is to find the possible relations between the gear geometry and the density gradients in the green component after compaction in addition to the friction effects. For this purpose several gears should be tested. To reduce the research costs, the finite element (FE) method is used. First a FE model of the compaction process is developed and verified. To investigate the relations between the density gradients and the gear parameters such as addendum diameter (da) and the face width (b) several gear geometries have been studied. The compaction of selected gears is simulated using the FE model. The simulations results which are the distribution of density in the green component are evaluated and discussed and conclusion are made based on them.</p

10 am – 2 pm + 6 pm – 10 pm. Work efficiency and quality of life of people working in Polish repertory theatres
No full textThe article focuses on the system of theatre work from 10 am to 2 pm and from 6 pm to 10 pm. This system appears to be some sort of legacy, something that has been functioning ‘for ages’, something unalterable, even traditional. Thus, it is habitual, invisible and intuitive, monopolistic for the discourse. It is due to these characteristics that this system of work requires a careful examination. The article discusses the results of a survey conducted by the author in which respondents assessed the effectiveness of the traditional work system and their quality of life in connection with work
