WITHDRAWN: Physicochemical processes of steam reforming in small spaces
Authors: Chen Junjie 
Published: July 2022

Abstract
The steam reforming of hydrocarbon or alcohol fuels has attracted increasing interest in the context of the production of hydrogen. However, there is a lack of a clear concept of the critical role that energy considerations play in an accurate explanation of steam reforming in small spaces. This study relates to the physicochemical processes for producing hydrogen by the catalytic endothermic reaction of methanol with steam in a thermally integrated microchannel reforming reactor. Computational fluid dynamics simulations are conducted to better understand the consumption, generation, and exchange of thermal energy between endothermic and exothermic processes in the reactor. The effects of design factors on heat transport characteristics and reactor performance are investigated. The results indicate that uneven flows can lead to incomplete utilization or local zones of varying reaction rate and heat transfer. Poor distribution of the fluids can lead to local hot spots which can decrease the reaction selectivity, reduce catalyst life, or lead to side reactions which may lead to dangerous uncontrollable side reactions. In addition to losses in selectivity and decreased product yield, poor thermal management can decrease the life of a catalyst and further reduce the efficiency of a reactor. Since the thermally coupled reactions are so closely coupled, neither reaction can run at a significantly different reaction rate at any point along the channel length. Each reaction will exhibit a peak in reaction rate at nearly the same position within the reactor with slower reaction rates before and after this peak, which leads to the need for a long reactor channel to ensure complete conversion. Unfortunately, the exothermic reaction is difficult to control with convenient combustion catalysts and fuels, and most of the combustion occurs near the fuel inlet. This uneven combustion results in uneven heat transfer to the endothermic reaction and poor overall reactor performance. Thermally matching the reactions is still further complicated by the inherent temperature gradients that are present along the flow length of the reaction channel. Any solution directed to resolving this thermal matching problem in a parallel flow configuration will add significant complexity or mass to the system.
WITHDRAWN: Mechanistic insights into the combustion of gas mixtures in small spaces
Authors: Chen Junjie 
Published: July 2022

Abstract
While flame propagation of gas mixtures in small spaces is feasible, the interplay of kinetics and transport in flame stability and combustion characteristics is poorly understood. This study relates to the mechanistic insights into the combustion of gas mixtures in small spaces. Flame propagation in microchannels is modeled using two-dimensional simulations with detailed multicomponent transport, gas-phase chemistry, heat loss through the wall, radical recombination at walls, and possible temperature discontinuity at the wall due to lack of thermal accommodation. Simulations are performed to gain insights into the performance of a millimeter-scale continuous flow reactor. A dimensionless number analysis is performed to better understand the heat transfer characteristics of the millimeter-scale continuous flow reactor. The factors affecting combustion characteristics and flame stability are determined for the millimeter-scale continuous flow reactor. The results indicate that combustion in small spaces can offer many advantages. The wall thermal conductivity is vital in determining the flame stability of the reactor. Further improvement in flame stability can be achieved by using anisotropic walls. When the catalytic rate increases to such an extent that the reactants cannot be transferred to the catalytic surface fast enough to keep up with the catalytic reaction rate, the reaction shifts to mass transfer control, and the catalytic reaction rate levels off regardless of further temperature increases. Increasing the rate of mass transfer of reactants to the catalytic surfaces would result in increased pressure drop and consequently a substantial loss of energy. Catalytically-supported, thermal combustion surmounts the mass transfer limitation. Catalytically-supported thermal combustion is achieved by contacting at least a portion of the carbonaceous fuel intimately admixed with air with a solid oxidation catalyst having an operating temperature substantially above the instantaneous auto-ignition temperature of the fuel-air admixture. Combustion is no longer limited by mass transfer as in the case of conventional catalytic combustion, and at the specified operating temperatures the reaction rate is substantially increased beyond the mass transfer limitation.
Speech Quefrency Transform (SQT)

Published: July 2022

Abstract
The fundamental frequency feature is crucial for Automatic Speech Recognition because its patterns convey a para-language and its tuning normalizes other speech features. Human speech is multidimensional because it is minimally represented by three variables: the intonation (or pitch), the formants (or timbre), and the speech resolution (or depth). These variables represent the hidden states of the local glottal variation, the vocal tract response, and the frequency scale, respectively. Computing them one by one is not as efficient as computing them together, so this article introduces a new speech feature extraction approach. The article is introductory; it focuses on the basic concepts of our new approach and does not elaborate on all applications. It demonstrates that the unit of a cepstral value, which is a spectral value of spectrums, is a unit of acceleration since its discrete variable, the quefrency, can be expressed in Hertz-per-microsecond. The article shows how to produce refined voice analysis from robust estimates and how to reconstruct speech signals from feature spaces. And it concludes that the pitch track of the new approach is as good as two open-source pitch extractors. Combining multiple processes, attenuating background noises, and enabling distant-speech recognition, we introduce the Speech Quefrency Transform (SQT) approach as well as multiple quefrency scales. SQT is a set of frequency transforms whose spectral leakages are controlled per a frequency-modulation model. SQT captures the stationarity of time series onto a hyperspace that resembles the cepstrogram when it is reduced for pitch track extraction.

Corporate social responsibility—A swap like role between a firm and its social stakeholders
Authors: Liu Mei , Ma Qing-Ping 
Published: July 2022

Abstract
We propose that 1) social stakeholders’ feelings of fairness and justice need to be satisfied, and they control social resources which firms need for profitable business operations; and 2) corporate social responsibility (CSR) practices from firms represent a swap-like tool in risk management to obtain stable supply of social resources from social stakeholders. To test these proposals, we use a sample of 20,275 deals by 2,488 firms from 48 home countries investing into 121 host countries. We find that high CSR performance significantly attenuates increases in shareholder value following foreign direct investment (FDI) announcements that cause positive abnormal returns, and significantly mitigates decreases in shareholder value following FDI announcements that cause negative abnormal returns. These results support our proposal that CSR acts like a swap.JEL Classification: F21, F23, M14, G14, G32.
Mutagenic and/or carcinogenic compounds in meat and meat products: Heterocyclic aromatic amines perspective
Authors: Oz E. , Oz F. 
Published: July 2022

Meat and meat products, which have a very important place in terms of nutrition, can endanger human health if they are not properly prepared and preserved. Meat and meat products except for products such as sushi, which are deliberately consumed raw, are generally consumed immediately after cooking. Cooking done properly gives meat and meat products their unique taste and aroma, increases their digestibility and makes them microbiologically safe. However, some harmful food toxicants can occur during the cooking process. Heterocyclic aromatic amines can be formed during cooking of the proteinaceous foods such as meat and meat products. Epidemiological studies have proved that heterocyclic aromatic amines are mutagenic and/or carcinogenic compounds. Therefore, having sufficient knowledge about heterocyclic aromatic amines will help to reduce the health risk posed by these com pounds. In this context, in the present study, basic information about heterocyclic aromatic amines that can be formed during the heat treatment of meat and meat products was reviewed.

Published: July 2022

Raman spectroscopy (vibrational spectroscopy) proved to be an effective analytical approach in the field of geology, semiconductors, materials and polymers. Over the past decade, Raman spectroscopy has attracted the attention of researchers as a non-destructive, highly sensitive, fast and eco-friendly method and has demonstrated the unique capabilities of food analysis. The use of Raman spectroscopic methods (RSMs) to assess the quality of meat and finished products is rapidly expanding. From the analysis of one sample, you can get a large amount of information about the structure of proteins, the composition of fatty acids, organoleptic parameters, autolysis and spoilage indicators, authentication of raw materials, technological properties. An important advantage of the method is the comparability of the results obtained with the data of traditional analytical methods. Traditional methods of determining the quality of meat are often time-consuming, expensive and lead to irreversible damage to a sample. It is difficult to use them in production conditions directly on the meat processing lines. Technological advances have made it possible to develop portable Raman spectroscopes to use directly in production. The article presents the basic principles of Raman spectroscopy, system atizes the results of the use of RSMs for the analysis of meat quality from different types of slaughter animals and provides tools for analyzing the data of the obtained spectra. Raman spectra have many dependent variables, so chemometric assays are used to work with them. Literature analysis has shown that currently there is no unified database of meat spectra in the world, standardized protocols for conducting research and processing the obtained results. In Russia, the use of RSMs is a new,

Published: July 2022

A trajetória acadêmica é marcada por alterações pessoais e profissionais. Dentre elas, pode-se observar impactos que corroboram para que consequências à saúde mental dos acadêmicos sejam desenvolvidas. Assim, o presente estudo tem como objetivo identificar os efeitos que a vida acadêmica pode provocar na saúde mental do graduando. A pesquisa trata-se de uma revisão de literatura narrativa e utilizou como base de dados as plataformas Scielo (Scientific Eletronic Library Online), LILACS (Literatura Latino-Americana e do Caribe em Ciências em Saúde), MEDLINE, Google Acadêmico e Revista Pró-UniverSus, através do critério de inclusão e exclusão, resultando em 16 artigos selecionados e 325 excluídos. Os resultados demonstraram que a graduação traz impactos mentais devido à transição da infância para a vida adulta, pelas responsabilidades e cobranças que são geradas diariamente no ensino superior e na nova rotina, o que ocasiona um desequilíbrio psicológico ao estudante e propicia o desenvolvimento de transtornos mentais ou psicossomáticos. Conclui-se que as instituições de ensino podem atuar como fatores estressores que provocam o desequilíbrio psíquico; em contrapartida, podem também proporcionar meios a partir dos quais o equilíbrio mental, social e físico seja reestabelecido.

Tough Talks Virtual Simulation HIV Disclosure Intervention for Young Men Who Have Sex With Men: Development and Usability Testing
Authors: Hightow-Weidman Lisa B , Muessig Kathryn , Soberano Zach , Rosso Matthew T , Currie Andrew , Adams Larsen Margo , Knudtson Kelly , Vecchio Alyssa 
Published: July 2022

Background
HIV status disclosure is an important decision with barriers specific to young men who have sex with men (YMSM), who have the highest rates of new HIV infections in the United States. Behavioral and social determinants of the difficulty to disclose can include fear of rejection, stigma, loss of financial stability, and lack of communication skills. Once able to disclose, a person may have increased access to social support and improved informed risk reduction conversations and medication adherence. Despite the known challenges and advantages of disclosure, there are few effective tools supporting this behavior.

Objective
To address this gap in disclosure interventions, the Tough Talks (TT) app, an mHealth intervention using artificial intelligence (AI)–facilitated role-playing scenarios, was developed for YMSM. This paper reports stages of development of the integrated app and results of the usability testing.

Methods
Building on the successful development and testing of a stand-alone interactive dialogue feature in phases 1-3, we conducted additional formative research to further refine and enhance the disclosure scenarios and develop and situate them within the context of a comprehensive intervention app to support disclosure. We assessed the new iteration for acceptability and relevance in a usability study with 8 YMSM with HIV. Participants completed a presurvey, app modules, and a semistructured qualitative interview.

Results
TT content and activities were based on social cognitive theory and disclosure process model framework and expanded to a 4-module curriculum. The AI-facilitated scenarios used dialogue from an utterance database developed using language crowdsourced through a comic book contest. In usability testing, YMSM reported high satisfaction with TT, with 98% (31/33) of activities receiving positive ratings. Participants found the AI-facilitated scenarios and activities to be representative and relevant to their lived experiences, although they noted difficulty having nuanced disclosure conversations with the AI.

Conclusions
TT was an engaging and practical intervention for self-disclosure among YMSM with HIV. Facilitating informed disclosure decisions has the potential to impact engagement in sexual risk behaviors and HIV care. More information is needed about the ideal environment, technical assistance, and clinical support for an mHealth disclosure intervention. TT is being tested as a scalable intervention in a multisite randomized controlled trial to address outstanding questions on accessibility and effect on viral suppression.
