Spectral and conductivity measurements insights on loading mechanisms of DMSO/water-kaolin complexes

Kaolin, a naturally occurring clay mineral renowned for its distinctive properties, holds significant importance across various industries. The integration of dimethyl sulfoxide (DMSO) into kaolin matrices, both in the presence and absence of water, has been extensively explored for its potential to enhance material characteristics. Addressing debates surrounding the proposed adsorption mechanism for the type I structure of DMSO, this study undertook a comprehensive physicochemical characterization of DMSO-kaolin complexes (DMSO-KCs) derived from untreated (UnK) and HCl-treated (HK) Egyptian ore, with a focus on elucidating the loading mechanism facilitated by water.Key insights gleaned from electrical conductivity, dielectric constant, and Fine Testing Technology – Fourier-transform infrared (FTT-FTIR) measurements, shedding light on the bonding nature of DMSO-KCs. FTT-FTIR analysis revealed two stages of water departure at 180 °C, with the final stage coinciding with the release of pyrolysis gases, confirming the catalytic degradation of DMSO. Through X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA), two distinct bonding types of DMSO molecules with kaolinite were identified: amorphous adsorbed (type I) and lattice-oriented intercalated (type II).Electrical characteristic evaluations within the temperature range of room temperature (RT) to 260 °C and frequency range of 42 Hz–1 MHz revealed that DMSO intercalation enhances the electrical properties of kaolin. Hydrated DMSO-KCs exhibited higher values of σac and ɛʹ compared to non-hydrated samples. The activation energy (Ea) values for HCl-treated samples were smaller than those of untreated ones. Alternating current (AC) conductivity analysis indicated predominantly ionic behavior with frequency and temperature dependency in both HCl-treated and untreated kaolin. Our findings substantiate the adsorption mechanism of Type I DMSO, highlighting its amorphous nature, instability, and catalytic degradation over time, in contrast to the intercalated type II. This elucidation is pivotal for understanding the behavior of DMSO-KCs across diverse applications, including electronics, ceramics, and materialsscience.

Human-Delivered Brushstroke Characterization using an Instrumented Brush Focused on Torque.

Pleasant brush therapies may benefit those with autism, trauma, and anxiety. While studies monitor brushing velocity, hand-delivery of brush strokes introduces variability. Detailed measurements of human-delivered brushing physics may help understand such variability and subsequent impact on receivers' perceived pleasantness. Herein, we instrument a brush with multi-axis force and displacement sensors to measure their physics as 12 participants pleasantly stroke a receiver's forearm. Algorithmic procedures identify skin contact, and define four stages of arrival, stroke, departure, and airtime between strokes. Torque magnitude, rather than force, is evaluated as a metric to minimize inertial noise, as it registers brush bend and orientation. Overall, the results of the naturally delivered brushing experiments indicate force and velocity values in the range of 0.4 N and 3-10 cm/s, in alignment with prior work. However, we observe significant variance between brushers across velocity, force, torque, and brushstroke length. Upon further analysis, torque and force measures are correlated, yet torque provides distinct information from velocity. In evaluating the receiver's response to individual differences between brushers of the preliminary case study, higher pleasantness is tied to lower mean torque, and lower instantaneous variance over the stroke duration. Torque magnitude appears to complement velocity's influence on perceived pleasantness.

Effects of environment and genotype on dispersal differ across departure, transfer and settlement in a butterfly metapopulation.

Active dispersal is driven by extrinsic and intrinsic factors at the three stages of departure, transfer and settlement. Most empirical studies capture only one stage of this complex process, and knowledge of how much can be generalized from one stage to another remains unknown. Here we use genetic assignment tests to reconstruct dispersal across 5 years and 232 habitat patches of a Glanville fritillary butterfly (Melitaea cinxia) metapopulation. We link individual dispersal events to weather, landscape structure, size and quality of habitat patches, and individual genotype to identify the factors that influence the three stages of dispersal and post-settlement survival. We found that nearly all tested factors strongly affected departure probabilities, but that the same factors explained very little variation in realized dispersal distances. Surprisingly, we found no effect of dispersal distance on post-settlement survival. Rather, survival was influenced by weather conditions, quality of the natal habitat patch, and a strong interaction between genotype and occupancy status of the settled habitat patch, with more mobile genotypes having higher survival as colonists rather than as immigrants. Our work highlights the multi-causality of dispersal and that some dispersal costs can only be understood by considering extrinsic and intrinsic factors and their interaction across the entire dispersal process.

Mazhar Bey’in Farkındalık Yolculuğu

It is known that content based on mythological structure can appeal to the common sense of taste of the reader and the audience. Joseph Campbell explains this situation through the Hero's Journey paradigm; explains the mythic fiction through the stages of departure, initiation and return. He explains that the narratives we read, watch or encounter are always “the same” story, within the framework of the concept of journey he proposes. This journey can be the physical transformation of the hero, as well as an initiation metaphor, which usually has psychological foundations. The movie Yol Ayrımı, written and directed by Yavuz Turgul, is a movie where we can see the initiation of the hero Campbell mentioned. In this study, the movie Yol Ayrımı will be read through the Hero's Journey paradigm, and the aspects that fit and depart from the cycle will be evaluated through the transformation of the leading role Mazhar Bey (Şener Şen) in the movie. In the research, which will be carried out using the qualitative analysis technique, the content analysis of the relevant movie will be carried out by using the content analysis method.

ПОЛИТИЧЕСКИЕ РЕАЛИИ СОВЕТСКОЙ ДЕЙСТВИТЕЛЬНОСТИ И ИХ ОТРАЖЕНИЕ В ПРОЗЕ В. АКСЕНОВА И С. ДОВЛАТОВА

The article compares the memoirs of dissidents and the prose of V. Aksenov and S. Dovlatov (books "In Search of a Sad Baby", "Craft", "Suitcase"). There is a difference in approaches to the creation of texts. In the memoirs of dissidents, the political and ideological aspects of emigration are reproduced, the stages of departure are described in detail. In the prose of the writers of the third wave, the image of the artist of the word, an exile, forcibly separated from his homeland, is comprehended. V. Aksenov and S. Dovlatov follow the tradition that has developed in literature - images of the power / poet opposition. Writers, like immigrants who are not professional writers, do not strive to document all the nuances of going to the West, their goal is to go beyond comprehending only the socio-political aspects of going abroad. Writers solve aesthetic problems, political realities for them are only a reflection of the entourage of external circumstances. Thus, V. Aksenov establishes successive ties between the creators of the "Silver Age" and the artists of the third wave of words. For the autobiographical hero S. Dovlatov, expulsion from the USSR and "relocation" to the United States is an opportunity to realize himself as a person freed from the ideological component, to comprehend the "particularity" of his existence.

Performance Simulation of the Transportation Process Risk of Bauxite Carriers Based on the Markov Chain and Cloud Model

China imports a large quantity of bauxite each year. Bauxite in fine particles with high moisture has a high risk of liquefaction during the maritime transportation process, which is harmful to the stability and safety of the carrier. To ensure safe shipping, it is necessary to pay attention to the effects of the operation of cargo, the ship’s maneuvering and the ocean environment during the whole transportation process. The simulation of the process risk helps to develop measures to intervene with the cargo behavior to keep the risk to an acceptable level. This study examined the transportation process of a bauxite carrier using the Markov Chain method at different stages of loading, unberthing, departure and sea navigation. Based on the risk transfer matrix of the operational status at different stages of transportation, a cloud simulation model was developed to analyze the transportation process risk of a ship carrying bulk bauxite. Results: the research revealed that the risk evolution rule of the solid bulk cargoes with potential liquefaction during the transportation process, especially bauxite. The risk alteration during the prophase of the transportation process conforms to the rule of the “spoon curve”. Conclusions: a simulation model of the process risk based on the Markov Chain Cloud is suitable for the simulation analysis of the transportation risk of the bulk bauxite carrier. The outcomes of this study may contribute to better safety management to prevent the occurrence of ship capsizing.

Backpacking Through an Ontology of Becoming: A Never‐ending Cycle of Journeys

AbstractBy adopting an ontological stance of becoming, this study traces qualitatively the journeys of contemporary backpacker tourists using the theoretical construct of the ‘Hero's Journey’ as a conceptual vehicle. This process allows for the development of a cyclical model of experience that illustrates the backpacker's experience in three stages of departure, initiation and return. This approach reveals the role that former backpackers play through the sharing of knowledge and the invaluable support they offer to novice backpackers through a network of support that is available to contemporary backpackers who choose to follow established backpacking trails. This never ending cycle of journeys becomes instrumental into the shaping of what this paper see as the common, collective consciousness of the backpacking experience and the evolution of the backpacking experience market.

Water and ethanol desorption in the flexible metal organic frameworks, MIL-53 (Cr, Fe), investigated by complex impedance spectrocopy and density functional theory calculations

The breathing behaviour of MIL-53(Cr) and MIL-53(Fe) upon water and ethanol desorption has been investigated by combining complementary experimental techniques including ThermoGravimetry Analysis (TGA), Differential Scanning Calorimetry (DSC) and Complex Impedance Spectroscopy (CIS). It was shown that two stages of solvent departure are involved in the desorption process, as revealed by (i) a change of the weight loss gradient in the TGA curve, (ii) the existence of a second endothermic peak in the DSC signal and (iii) a sudden drop and/or profile change of the ac conductivity in CIS. All these features are observed around a typical temperature T(c), for which the framework contractions, caused by the solvent desorption, occur. Moreover, it is shown that these modifications are more pronounced when the magnitude of the breathing is higher, as illustrated by the comparison of the water/MIL-53(Cr), ethanol/MIL-53(Cr) and water/MIL-53(Fe) systems. CIS data were further analyzed in the light of DFT calculations which provided the preferential arrangements of the molecules within the pores and the resulting host/guest interactions. It could then be proposed that (i) the polarization conductivity results from the local re-orientation of the μ(2)-OH dipoles bonded to the metal atom from the hybrid solid, i.e. Fe or Cr, and (ii) that dc conductivity, which can be ascribed to a proton propagation via a Grotthus mechanism, is favoured when the solvent molecules form strong hydrogen bonds between each other.

Spectroscopic study of a supersonic plasma jet generated by an ICP torch with a convergent-divergent nozzle

A supersonic argon and argon-hydrogen (3-5{%}) plasma jet generated by an induction plasma torch is studied by means of the methods of optical emission spectroscopy. The torch was operated at the input power of 20 kW and near atmospheric pressure. The supersonic jet with a periodic structure of expansion and compression zones is created by expanding the plasma through the Laval nozzle into a chamber maintained at the pressure around 1.8 kPa. Atomic argon lines with the upper level energies ranging from 13.3 to 15.5 eV, continuum emission and Hβ line profile are used to evaluate plasma parameters such as temperature and electron number density. Analysis based on the Boltzmann diagram, line-to-continuum ratio, population of continuum extrapolated level and Stark broadening reveals various stages of departure from thermodynamic equilibrium in the plasma flow. It is shown, among others, that the temperature derived from Boltzmann diagram does not follow the jet structure and reliable determination of electron temperature is questionable. An addition of several percent of hydrogen results in a significant quenching of populations of atomic states and nonequilibrium behaviour of continuum radiation.

A Stage of Migration Approach to Understanding Nursing Home Placement in Latino Families

ABSTRACT This article introduces a dual application of Drachman and Ryan's stage of migration framework by applying the framework to an analysis of experiences of 25 nursing home residents with a prior history of migration from Cuba, the Dominican Republic, Ecuador, Mexico, and Puerto Rico. The stages of premigration and departure, transit, and resettlement are discussed in relation to research findings about the residents' earlier migration to the mainland United States and more recent move into a nursing home. Implications for social work practice with residents, families, and as members of interdisciplinary teams are addressed.
