Computational Fluid Dynamics Studies of Gas-Solid Flows in a Horizontal Pipe, Subjected to an Adiabatic Wall, Using a Variable Gas Properties Eulerian Model
Authors: Patro Brundaban , Kumar K. Kiran , Krishna D. Jaya 
Published: March 2019

Abstract
In the present paper, a variable gas properties Eulerian model is employed to model the gas-solid heat transfer in a three-dimensional horizontal pipe, subjected to an adiabatic wall. The numerical model has been validated with the benchmark experimental data and other theoretical results available in the literature, and found satisfactory agreements. Moreover, the numerical heat transfer results considering the variable gas properties (i. e. density, dynamic viscosity, thermal conductivity, and specific heat) and constant gas properties are compared. It is noticed that the variable gas properties significantly affect the heat transfer, when compared to the constant gas properties. Therefore, the consideration of constant gas properties for the prediction of heat transfer may not be suitable in gas-solid flows, subjected to an adiabatic wall. Moreover, the temperature profiles, solid volume fraction profiles, and gas-solid Nusselt number are discussed. Finally, the pressure drop prediction with respect to the solid loading ratio is studied, and found that the pressure drop slightly decreases with increasing the solid loading ratio.

Abstract
Conjecture 4 of Voiculescu implies that almost normal operators must satisfy a Fuglede-Putnam theorem, namely [T
∗, X] is a Hilbert-Schmidt operator whenever [T, X] is in the same class for an arbitrary operator X. In this note, a partial answer to this question is given, namely when X ∈ 𝓒4, the Fuglede-Putnam theorem holds.

Authors: Zhang Pingsheng , Xin Yong , Ai Fanrong , Cao Chuanliang 
Published: March 2019

Abstract
The combination of double-fillers with synthetic polymers has been an attractive route for developing bone scaffolds. In this article, polycaprolactone (PCL) scaffolds were produced using a selective laser sintering (SLS) technique; multi-walled carbon nanotubes (MWCNTs) and eggshell (ES) were used as two fillers to improve their mechanical and osteogenic properties. The crystal phase, morphology, hydrophilicity, biocompatibility and mechanical properties of the composite scaffold were detected using X-ray diffraction, scanning electron microscope, water contact angle tester and in vitro cell test, respectively. Results show that ES improved the hydrophilicity and biocompatibility of the scaffolds obviously, whereas MWCNTs enhanced their compression and tensile strength. The PCL/ES/MWCNTs composited scaffold prepared by SLS possess excellent biocompatibility and mechanical strength, showing a potential application for bone repair.

Published: March 2019

Abstract
Exploitation and utilization of mineral resources have played a vital role in China’s rapid economic developments. Although the history of mineral processing is quite long, technologies in this field have varied with the changes of market demands. This is particularly the case for minerals whose high-grade deposits are depleting. The aim of this review is to present our recent efforts on developing new routes for the utilization of low-grade minerals, such as iron ores and brine-containing lithium. The emphasis on the two minerals lies in the fact that iron plays a vital role in modern-day civilization and lithium is a key component in electric vehicles for transportation. Furthermore, the utilization of magnesium chloride reserves, one of the largest wastes in western China, as raw materials for fabrication of functional materials is also included in this review.
Index as scaffold to logical and final interpretants: Compulsive urges and modal submissions
Authors: West Donna E. 
Published: March 2019

Abstract
This inquiry capitalizes on the relational character of Peirce’s index. Its evolution from object finder in the physical world, to enhancer of communication between minds, to modal/perspectival coordinator is examined. Its relational character organizes events into episodes, and obviates perspectival alterations in dialogic reasoning. This shift demonstrates Peirce’s last word regarding Index: a sign intrinsically dialogic, whose interpretants increase levels of consciousness, and advance communicational interaction by commanding self/others to believe/act in novel ways.
Its power to coordinate specific, vivid images provides index with the means to suggest novel propositions, assertions, and arguments. Peirce memorializes this relational role by characterizing index as Dicisign, and afterward as Pheme (1904, CP 8.334–8.339; 1906, MS 295: 26; 1908, EP 2: 489–490). As truncated Argument, Index provides the catalyst for interpreters to determine the meaning of interpretants be they Energetic, Logical or Final. Its non-symbolic character provides interpreters the impetus to utilize inferencing powers to attach meanings, thus expanding kinds of interpretants. Index constitutes the most diverse semiotic tool for interpreters – it traces subtle deontic, epistemic, and logical shifts. In situating and resituating events in time, place, and participatedness, Index aptly measures actual and potential shifts in affect, attention, location, credibility, and the like.
Ultimately, index integrates the logical with the phenomenological and the empirical with the semiotic – when it deploys relational operators to trace event templates and to predict participant’s perspectives. As such, interpreters restructure thought and action and recommend sound courses of action for diverse event participants.
HSB-1 Inhibition and HSF-1 Overexpression Trigger Overlapping Transcriptional Changes To Promote Longevity in Caenorhabditis elegans

Published: March 2019

Abstract
Heat shock factor 1 (HSF-1) is a component of the heat shock response pathway that is induced by cytoplasmic proteotoxic stress. In addition to its role in stress response, HSF-1 also acts as a key regulator of the rate of organismal aging. Overexpression of HSF-1 promotes longevity in C. elegans via mechanisms that remain less understood. Moreover, genetic ablation of a negative regulator of HSF-1, termed as heat shock factor binding protein 1 (HSB-1), results in hsf-1-dependent life span extension in animals. Here we show that in the absence of HSB-1, HSF-1 acquires increased DNA binding activity to its genomic target sequence. Using RNA-Seq to compare the gene expression profiles of the hsb-1 mutant and hsf-1 overexpression strains, we found that while more than 1,500 transcripts show ≥1.5-fold upregulation due to HSF-1 overexpression, HSB-1 inhibition alters the expression of less than 500 genes in C. elegans. Roughly half of the differentially regulated transcripts in the hsb-1 mutant have altered expression also in hsf-1 overexpressing animals, with a strongly correlated fold-expression pattern between the two strains. In addition, genes that are upregulated via both HSB-1 inhibition and HSF-1 overexpression include numerous DAF-16 targets that have known functions in longevity regulation. This study identifies how HSB-1 acts as a specific regulator of the transactivation potential of HSF-1 in non-stressed conditions, thus providing a detailed understanding of the role of HSB-1/HSF-1 signaling pathway in transcriptional regulation and longevity in C. elegans.
Influence of new snow on growth and melting of sea ice
Authors: Zavyalov D. D. , Solomakha T. A. 
Published: March 2019

Numerical experiments were carried out using the thermodynamic model with the aim to optimize choice of parameterization of the density of fresh snow, its albedo, and thermal conductivity coefficient in order to reproduce the seasonal evolution of ice thickness in the North-Eastern part of the Sea of Azov. The simulation results were compared with each other as well as with the observations obtained at the costal station of the Southern Scientific Center of the Russian Academy of Sciences in the Taganrog Bay. It is shown that small differences in the schemes of parameterization of physical and thermal properties of snow and ice cover may result in significant scatter in the simulation results. To assess the quality of the forecasting of the seasonal course of the ice thickness, the standard deviation of the calculated ice thickness from the average value for the period of measuring ice thickness, the standard deviation, the correlation coefficient, and the verification of the forecast were determined. Based on the analysis of these parameters, the optimal configuration of the snow layer parameters is proposed, which allows adequate reproducing of the seasonal thermal dynamics of the sea ice thickness. For the conditions of winter 2010/2011 the most close values of calculated ice thickness to results of the measurements in the North-Eastern part of the Taganrog Bay were obtained by determining the dependence of the density of fresh snow on the temperature in the near-surface layer of the atmosphere by the algorithm CLASS, albedo of the snow surface - by the scheme EHAM5, and the coefficient of thermal conductivity of snow – by the formulas of N.I. Osokin or M. Janson.

Published: March 2019

The Kolka Glacier, which rushed down the Genaldon valley on September 20, 2002 (North Ossetia), is now recovering after this catastrophe. One of the most important ways to predict a new disaster is to determine the rate of ice accumulation of the new glacier and to monitor the glacier volume regularly, since its trigger mechanisms have not yet been fully studied. Recent changes of the Kolka Glacier were investigated by means of ground stereoscopic photography. The field works were carried out in 2014, 2016 and 2017. Shooting was made manually with a digital camera Canon 5D Mark II (without using a tripod) at arbitrary points, the distance between which did not exceed 100 m. The reference points were placed on the elevated relief forms on the glacier surface and coordinated by a differential GNSS receiver in the "fast static" mode. Laboratory processing of the photos was performed using Agisoft Photoscan software in automatic mode, except for the procedure of identification of reference points on stereo images. The processing made possible to obtain digital models of the glacier surface in Geo-TIFF format, the vertical error of which amounted to 0.7 m, while the horizontal one – 2.3 m. In 2014–2017, the maximal increase in height of the surface (up to 30 m) was recorded in the low part of the glacier tongue that was the result of advancing of the Kolka front along the ice-free surface. Mean annual increase in the surface elevation was equal to 2.2 m/year. Lowering of the surface in some areas may be explained by the slowing-down of the glacier flow rate, which led to the appearance of thermokarst. The glacier volume increased by 7.4±0.7 million m3. As a result, the glacier tongue advanced by 50–70 m. Average over 2014–2017 increasing in the surface elevation (2.2 m/year) was slightly smaller than in 2004–2014 (3 m/year). Quick growth of the Kolka Gacier contrasts sharply with decreasing of volume of the representative Caucasus, Djankuat and Garabashi, over the same period.
