Quantum thermodynamics of hydrogen in nano-structured materials—H2 in carbon nanotubes
Authors: Chatzidimitriou-Dreismann Aris 
Published: April 2022

Abstract
Modern quantum theory of correlations predicts, and reveals, new counter-intuitive dynamical effects of hydrogen in nano-structured materials, being of considerable importance for basic research as well as for technological applications. To support this claim, here the focus is on H2 molecules in carbon nanotubes and other nanocavities, as experimentally investigated with the well established technique of incoherent inelastic neutron scattering (INS). In particular, the experimentally determined momentum and energy transfers from an H2 molecule in a carbon (C-) nanotube resulting in roto-translational motion along the nanotube axis, appear to (1) either violate the standard conservations laws, or (2) attribute the translating H2 molecule a highly reduced inertia, as quantified by the effective mass M
eff ≈ 0.64 a.m.u. (atomic mass units), instead of 2 a.m.u. for an isolated molecule. This counter-intuitive INS-observation has no conventional interpretation, but it can be qualitatively interpreted “from first principles” in the frame of modern theories of quantumness of correlations and Quantum Thermodynamics (QTD). This analysis also provides a surprising new physical insight: The nano-structured cavities do represent quantum systems which contribute to the quantum dynamics of the hydrogen translational dynamics, and thus to the hydrogen transport in the studied materials. This insight may also have far-reaching consequences for technological applications and material sciences (e.g. fuel cells, H storage materials, etc.), since it concerns the choice and design of “optimized” materials adsorbing or carrying hydrogen.
Fine-Grained Sediment Characterization and Process Monitoring Using Nuclear Magnetic Resonance (NMR)
Authors: Zhao B. , Santamarina J. C. 
Published: April 2022

Abstract
The intrinsic magnetic moment of hydrogen nuclei allows them to interact with externally imposed magnetic fields; then, nuclear magnetic resonance (NMR) can be used to probe the pore space of wet soils using the water molecules in pores. Surface relaxivity at pore walls combines with molecular diffusion to produce a relaxation rate that is inversely proportional to the pore size in saturated specimens or the mean distance to a pore wall in unsaturated soils. We used NMR to nondestructively characterize pore size distribution, monitor changes in pore space during sedimentation, and track the evolution of water conditions during drying and infiltration. Results show that the evolution of relaxation time distribution reflects pore size contraction, water film thickness reduction, and pore water redistribution. In all cases, the mean relaxation time and water content exhibit a unique relationship for both saturated and unsaturated soils; we propose a parallel plate model to interpret this relationship that only depends on surface relaxivity and specific surface area. Finally, we impose a magnetic field gradient to obtain spatially resolved relaxation spectra; this technique shows the evolution of moisture profile with depth and changes in moisture transport mechanisms during 1D drying. The carefully designed experiments demonstrate the potential of NMR spectroscopy as an effective tool to monitor water conditions and characterize the pore space in fine-grained sediments.
Formulation of Definitions of Consciousness on the Methodological Basis of Realism
Authors: Diržys Adas 
Published: April 2022

In this paper, the traditional question – what is mind? – is suggested to be treated from the metareflective realist stance from which different determinations of consciousness could be apprehended as always instantiated and dependent on their definitions. Methodological differentiation between what is representational and what is non-representational is expressed as a divergence between particular definitions of consciousness and the ontological X, in this context, acting as a universality of consciousness. The derivation of this position is reached through the investigation of François Laruelle’s non-standard philosophy, Wilfrid Sellars’s critique of the myth of the given and Iain Hamilton Grant’s revisionary study of Schelling’s naturphilosophie.

Authors: Kucheryaviy Oleksandr 
Published: April 2022

The article is devoted to the problem of substantiation of the integral target orientation of preparation of future teachers of institutions of higher pedagogical education for professional activity in the conditions of digitalization of society: systems of their professional-digital competences. The main conceptual idea is put forward: professional-digital competencies of a teacher of a higher pedagogical educational institution are in isomorphic dependence on his/her professional functions and form a holistic system - a reference model of the target landmark of the digitalized educational process in graduate and postgraduate studies. The integral-functional dimension describes the procedure for establishing a holistic set of updated teacher functions in the digital educational environment ofa pedagogical university. The set of the following criteria for their search is outlined: 1) the specifics of thefunctional content of the types of teaching activities, taking into account the process of digitization of higher education; 2) the subject of the teacher's relations with future teachers and public life; 3) the nature of the relevant links. According to all criteria in their unity, three core professionally defined functions are defined: heuristic-digital, managerial-digital and self-development-digital. To these are added purely instrumental general professional - executive-digital, technical-digital and the function of compliance with digital security.
The differences between the concepts of "professional-digital" and "digital" competence are emphasized. The concept of the system of professional-digital competencies of a teacher of a higher pedagogical educational institution as a holistic and interconnected set of their components, adequate to his/her certain professional functions in the digital environment, is formulated. The following relevant system of competencies is defined: heuristic-digital aspect (competencies in the areas of pedagogical innovations, digital content of personal and professional development, in particular, worldview and existential orientation, etc.); managerial and digital aspect (competence of the teacher of diagnostic and prognostic, motivational, design, organizational, stimulating and control functional and managerial nature); self-development-digital aspect (important for personal, professional and professional-cultural development of the teacher's competence); aspect of digital culture (digital competencies, highlighted in the literature, important for information retrieval, reception, processing and output, use of basic and application software, solving technical problems, personal data protection, copyright, etc.)

Published: April 2022

The essence and significance of the formation of psychological space as a factor of successful adaptation to school of children with speech disorders are analyzed. It is determined, that the violation of the child's psychological space causes a painful attitude to everything around and contributes to the formation of internal psychological conflict, which inevitably leads to loss of learning motivation, reduced cognitive activity, disrupted relationships with teachers and peers. The aim is to prove that the formation of psychological space will contribute to the successful adaptation of children with speech disorders to study in primary education.
The methods of research of the outlined problem are theoretical methods that allowed to separate the provisions that needed to be verified. Empirical methods allowed to identify the level of adaptability of children to study in an educational institution, among them: observation, conversation, testing, statement experiment, processing of research results (presented as a percentage).
It was found, that psychological space, a sense of comfort, safety is one of the most important areas of human life, and a properly constructed psychological space can provide a sense of security in the school environment during the period of adaptation.
It is noted, that in order to facilitate the adaptation of children to learning, in the primary level should be a deep and expanded diagnosis of readiness for learning activities and preparatory work with children who have insufficient school adaptation.
The diagnostic procedure and the program of research of psychological space as a factor of successful adaptation to school of children with speech disorders are described. The conditions of formation of personal space of a junior schoolchild are defined.
It is concluded, that the purposeful formation of psychological space makes it possible to ensure the success of the process of adaptation to learning at school. Psychological space, a sense of comfort, security is one of the most important areas of human life and from the first days of children's schooling, a teacher must ensure that school attendance for a child is not burdensome, form a cognitive learning motive that would dominate in the future studying

This investigation aimed to compare the sexing accuracy of frontal (FS) and maxillary (MS) sinus indices with multislice computed tomography (MSCT) in Brazilian adults. This cross-sectional study was conducted on 100 MSCT examinations (50 males and 50 females). The height, width, and diameter of the FSs and MSs were obtained with the RadiAnt software to measure four indexes (I): FSI-1 and MSI-1 (both width/ diameter); FSI-2 and MSI-2 (both height/diameter). Areas under receiver operating characteristic curves (AUROC) were determined. Sensitivity, specificity, likelihood ratio (LR), and accuracy values ​​were also calculated. The highest area under the ROC curve for the FS was obtained by the FSI-1 (0.712 ± 0.052; p < 0.001), whereas for the MS it was found in the MSI-2 (0.431 ± 0.058; p = 0.232). FSI-1 showed greater specificity (64%) in predicting female sex as well as greater accuracy (64%) and LR (3.16). MSI-1 had the highest sensitivity value (68%) in estimating male sex and the second highest LR value (2.13). The FSI-1 developed in the present study exhibited higher accuracy compared to the other evaluated indices, which reinforces its importance for future studies with other populations.

Применение активированных углей для извлечения веществ органической природы находит все большее распространение в различных областях промышленности. В настоящем исследовании проведено сравнение равновесных характеристик сорбции п-гидроксибензальдегида из водных растворов углями различных марок: отечественными АГ-3И, ВСК-400 (НПО «Неорганика», Россия) и зарубежным GAC 1240W (Norit, Нидерланды). В работе получены изотермы сорбции альдегида в диапазоне концентраций 5·10-4-3·10-2 моль/дм3 при температуре 298К в статических условиях. Отмечена высокая сорбционная способность изученных образцов сорбентов по отношению к гидроксибензальдегиду. В случае сорбции на угле Norit GAC 1240W наблюдается формирование монослоя сорбата на поверхности, в области высоких концентраций наблюдается дополнительное поглощение за счет возникновения сорбат-сорбатных взаимодействий. Использование АГ-3И и ВСК-400 также сопряжено с проявлением нескольких механизмов (сорбат-сорбент и сорбат-сорбат), которые реализуются параллельно. Данные о полимолекулярной сорбции подтверждаются сравнением емкостных характеристик углей по гидроксибензальдегиду, по молекулярному иоду и метиленовому голубому.
Для описания изотерм сорбции использован формальный подход, основанный на применении линеаризованных уравнений сорбции известных теорий: Ленгмюра, Фрейндлиха, Темкина и Дубинина-Радушкевича. Отмечено, что наибольший коэффициент корреляции линейной зависимости отмечается для Norit GAC 1240W в координатах уравнения типа Ленгмюра, для АГ-3И и ВСК-400 – для уравнения сорбции типа Фрейндлиха.
Величины коэффициента распределения альдегида в системе раствор – активированный уголь указывает на его монотонное снижение с ростом концентрации сорбтива, что связано, прежде всего, со стерическими затруднениями при его диффузии в поры угля.
Evaluation and Updates for the USGS San Francisco Bay Region 3D Seismic Velocity Model in the East and North Bay Portions
Authors: Hirakawa Evan , Aagaard Brad 
Published: April 2022

ABSTRACTWe update the eastern and the northern portions of the detailed domain of the U.S. Geological Survey San Francisco Bay region 3D seismic velocity model (SFVM) based on comparisons of recorded and synthetic ground motions from 20 moderate (Mw 3.7–4.6) earthquakes. We modify the current SFVM (v.08.3.0) by assigning alternate property-versus-depth relations to the existing 3D geologic model. In some places, changes correspond to reassigning correct relations in which geologic units appear to be mislabeled, and in other places we subdivide geologic units where mapped geologic boundaries are missing from the 3D models so that we can implement a velocity contrast across a boundary. We also make ad hoc adjustments to velocity rules near the surface in some areas to better fit arrival times (specifically, in the Livermore basin). The updates reduce misfits in waveform correlation, travel time, cumulative absolute displacement, and peak ground velocity and are included in v.21.1 of the model. The selected earthquakes are small enough so that we neglect finite-source effects and model them as point sources. This allows us to assume that observed waveform characteristics are the result of path effects, and discrepancies between synthetic and recorded motions arise from misrepresentation of the elastic properties. Our analysis suggests refining the 3D geologic model, and adjusting the rules assigning properties to the geologic units will further improve the accuracy of the SFVM for simulating earthquake ground motions.

Authors: Marentek Erika Christy , Budiati Tutuk , Ekowati Juni 
Published: April 2022

Background: Cinnamic acid and its derivatives have been widely studied for their efficacy because of the pharmacological effect on good health and well being. Microwave irradiation is more time effective to synthesize than conventional heating method because it conducts heat faster and shortens the reaction time. Objective: This study aimed to synthesize 4-hydroxy-3-methoxycinnamic acid using microwave irradiation and its antiplatelet activity by blood clotting time method. Methods: Synthesis of 4-hydroxy-3-methoxycinamic acid with malonic acid and 4-hydroxy-3-methoxybenzalehyde as a starting material using ammonium acetate catalyst with microwave irradiation (960 Watt, 4 minutes). The synthesis results were tested for purity by thin-layer chromatography, a melting point determination and structure identification (UV-Vis, infrared, and proton NMR spectrometry). The antiplatelet activity test consisted of a negative control group CMC-Na, a positive control acetosal, cinnamic acid, and 4-hydroxy-3-methoxycinnamic acid, each group consisted of 3 different doses, namely 0.0037 mmol/Kg (I), 0.0069 mmol/Kg (II) and 0.0139 mmol/Kg (III). Results: Synthesis of 4-hydroxy-3-methoxycinamic acid had a yield percentage of 30.55%. The test results showed that the 4-hydroxy-3-methoxycinnamic acid compound has antiplatelet activity with an ED30 value of 1.3080 mg/Kg BW and antiplatelet activity comparable to acetosal. Conclusion: 4-hydroxy-3-methoxycinamic acid can be synthesized by microwave irradiation and had antiplatelet activity 1.7 fold greater than cinnamic acid.

O Serviço de Nutrição e Dietética em um hospital tem como finalidade o cuidado e o papel de elevada importância, ao produzir alimentos para pacientes com diversas enfermidades visando tratar, prevenir e recuperar o estado de saúde desses indivíduos. O objetivo do artigo foi avaliar as temperaturas durante o porcionamento dos alimentos em uma UAN hospitalar localizada no município de Nova Lima - MG, servindo cinco refeições por dia: desjejum, almoço, lanche da tarde, jantar e ceia, fornecendo em média 900 refeições por mês e funcionando todos os dias. Foram analisadas as temperaturas de 30 amostras diferentes, em um período de 15 (quinze) dias, conforme o cardápio do dia e a observação de temperatura ocorreu entre os horários de 16h e 50 minutos e 17h e 30 minutos. A análise das temperaturas demonstrou que há falhas nos processos de distribuição de 77% dos alimentos servidos para os pacientes, sendo que somente 23% das preparações se mantiveram dentro dos parâmetros permitidos pela legislação vigente, que preconiza que tais alimentos estejam com temperatura acima de 60°C. Torna-se fundamental o treinamento constante dos manipuladores, a aplicação das boas práticas de fabricação e dos procedimentos operacionais padronizados em todas as etapas do processamento dos alimentos e a presença do Nutricionista como responsável técnico por estes estabelecimentos.
EIXO INTESTINO-CÉREBRO E SUA INTERFERÊNCIA NO TRANSTORNO DEPRESSIVO: REVISÃO INTEGRATIVA
Authors: Costa José Mateus , Oliveira Silva Stephanie , Santana Alves Leite Tailana 
Published: April 2022

O eixo Intestino cérebro é formado por um extenso conjunto de vias neurais que vão desde o SNC até o SNE. Muitos dos neurotransmissores que atuam nestes sistemas são sintetizados por células intestinais ou por influência da microbiota local. Alguns problemas intestinais como a SII, podem interferir, atenuar ou até causar problemas psicológicos como a Depressão. Baseado nisso, o artigo teve como objetivo de compreender a relação Intestino-cérebro e as interferências no distúrbio depressivo. Trata-se de um estudo bibliográfico com uma abordagem integrativa. Os artigos científicos foram pesquisados nas seguintes bases de dados: LILACS, BVS e SciELO, utilizando como descritores “intestine and brain”, “intestinal microbiota and depression”, “bowel and depression. Ao total foram analisados 9,591 periódicos, dos quais apenas 8 participaram do estudo. Notou-se uma grande relação entre as Doença de Crohn e Retocolite e Ulcerativa com o aparecimento de sintomas depressivos principalmente em mulheres. Investiga-se que as causas deste problemas pode ter um origem psicossomática e que pode ter início na infância por mal hábitos alimentares uso de antibióticos, má relação familiares entre outros. Baseado nesta relação novas estratégias terapêuticas passaram a ser estimuladas, como o uso de probióticos, atenção plena, terapia, autocitação e terapia comportamental.
