Substitution of equations for evaluation of energy consumption in rotor-stator mixers
Authors: Seminskyi Oleksandr 
Published: December 2022

In the presented publication, an attempt to develop the theory of mixing by considering rotor-stator mixers from the standpoint of mechanical mixing devices was made.
The results of the research on energy consumption are given in the form of analytically substituted expressions for determining power and pressure difference as well as a flow rate in a stage of rotor-stator mixer composed of a pair of the perforated rotor and stator elements with a gap between them, depending on the features of the design, dynamic characteristics of the rotor and flows. The interrelationships between power, pressure difference, and flow rate in the stages of rotor-stator mixers are established. This makes it possible to define the characteristics of mixers, carry out their calculations and reasonably accept the rational design and processing parameters. The peculiarities of the components in obtained equations are indicated. Partial cases of the equations for power consumption in stages of rotor-stator-mixers operated in pulse and impulse modes are considered. The invariant form of obtained equations would help to ease the scaling of rotor-stator mixers.

Published: December 2022

Background. The use of various libraries often leads to a decrease in the speed of the web application and the complexity of the execution of the program code. The object of this study is the process of storing and managing the data of the client part of the web application, the subject of the research is the software methods of managing the local state of the data of the web application.
Objective. The goal of the article is the reduction in the data processing time of web applications relative to existing software methods.
Methods. The main idea of ​​the proposed method is to use an atomic approach to the state of the web application data. Having an arbitrary entity, in the general state of the web application, a state fragment is created that is responsible only for this entity. Such a fragment is independent of other state fragments and can only work with the encapsulated entity. Using encapsulation, the configuration of an entity is passed to the React Context API as an object containing data and functions that modify it.
Results. The developed framework method was compared with popular state management libraries Redux, MobXState-Tree and Recoil. Comparing each of the test scenarios in a percentage ratio, an average decrease in program execution time by 17% was obtained.
Conclusions. The Redux, MobXState-Tree, and Recoil libraries were selected for the research of existing software methods. The analysis of methods was performed using the SonarQube utility. To evaluate the results of the software methods, the Google Chrome browser utility DevTools was used. The proposed optimized software method allows to reduce the data processing time and optimize the state management of web applications.
Keywords: web application, optimization, local state of data, Redux, MobXState-Tree, Recoil.
Амплитудная, балансная и однополосная модуляции Хартли
Authors: Коханов Александр Борисович 
Published: December 2022

Разработан новый вид модуляции — амплитудная модуляция Хартли (АМХ), которая отличается от амплитудной модуляции (АМ) наличием двух ортогональных составляющих амплитудно-модулированного сигнала, что позволяет увеличить коэффициент полезного действия АМХ до 90% по сравнению с 33% обычной АМ при максимальном значении индекса модуляции М = 1. В качестве сигнала несущей частоты используется сумма сигналов косинусной и синусной составляющих, что соответствует функции cas(a) = cos(a) + sin(a), которая применяется в качестве ядра преобразования Хартли. На основе АМХ разработаны двухполосная амплитудная модуляция Хартли БМХ (балансная модуляция Хартли) и амплитудная модуляция с одной боковой полосой Хартли (ОБПХ). Показано, что АМХ, БМХ, ОБПХ модуляции обеспечивают энергетический выигрыш 6 дБ, что позволяет увеличить дальность связи в два раза по сравнению с использованием АМ, балансной модуляцией (БМ) и модуляцией с одной боковой полосой (ОБП) при прочих равных условиях передачи и приема сигналов. При сохранении заданной дальности связи без изменения можно понизить мощность передатчика при использовании АМХ, БМХ, ОБПХ модуляций в 4 раза по сравнению с АМ, БМ и ОБП модуляциями соответственно. Применение АМХ и ОБПХ модуляций позволяет осуществлять передачу узкополосных сигналов на значительные расстояния на длинных, средних и коротких волнах через ионосферные каналы связи с высокой эффективностью, где использование широкополосных сигналов затруднительно.

Published: December 2022

The necessity of creating innovative protective structures for armoring machinery and equipment is analyzed. A comparative analysis of high-strength materials used for local and individual body armor has been carried out. The relevance of the development of domestic universal armored materials that combine high strength properties and radio transparency based on lightweight technological magnesium aluminosilicate glass-ceramic materials with high performance properties at the level of world analogues has been determined. Were formulated the purpose and tasks of the work, which consist in: analysis of the current state of development of glass-ceramic materials for armor protection; development of magnesium-aluminosilicate glass-ceramic materials with high armor resistance, impact resistance and radio transparency; investigation of the operational properties of the developed glass-ceramic materials and their armor resistance; assessment of the competitiveness of the developed glass-ceramic materials. A set of requirements for a glass matrix for obtaining protective glass-ceramic materials has been formulated. Compositions and technological parameters for the production of glass-ceramic materials under the conditions of two-stage low-temperature heat treatment have been developed. The study of the electrical properties of experimental glass-ceramic materials made it possible to establish the possibility of effective functioning of on-board wireless communication systems when using the developed materials as elements of armor protection. It was found that the developed glass-ceramic materials are characterized by high operational properties (KCU = 5.8 kJ/m2; HV = 10.4 GPa; K1C = 8.5 MPa∙m1/2) and armor resistance STANAG 4569 (level 2). The competitiveness of the developed glass-ceramic materials based on mullite is analyzed. It has been established that a significant increase in fracture toughness and a decrease in the density of the developed material when comparing properties with a similar armor element (corundum-based plate) will significantly reduce the weight of the armor elements by ≈1.4 times and its cost by five times, while maintaining its protective properties.

Unveiling the True Micro-Structure in PdRu Immiscible Alloys and Its Application in Alkaline Hydrogen Evolution Reaction
Authors: Hu Zheng , Li Hui , Zhao Wenbo , Zhou Wei , Hu Shi 
Published: December 2022

Abstract
The structure information in a disordered atomic system could not be acquired from the daily X-ray diffractometers, but has to resort to the synchrotron sources. The pair distribution function from the synchrotron X-ray and neutron scattering reflects the local bond information regardless of the crystallinity, but the limited access to these high-energy light resources prevents them from wide use. Herein we developed a microstructure analysis framework to study the immiscible binary alloys, through the integration of local elemental segregation analysis, electron-based pair distribution function, the corresponding wavelet coherence spectrum, and ab-initio level simulation. All the information could be obtained from an in-house transmission electron microscope equipped with an energy dispersive spectroscope. A series of nanoparticles based on immiscible Pd-Ru alloys were chosen as the model catalysts for hydrogen evolution reaction and the structure-performance relationship was established based on the electrochemical tests and the structure information from the analysis toolkit we developed.
Viscous fingering in volatile fluid towards spontaneous evolution of well-ordered 3D patterns
Authors: Rakshe Makrand , Gandhi Prasanna 
Published: December 2022

Abstract
Mimicking nature using artificial technologies has always been a quest/fascination of scientists and researchers of all era. This paper characterizes viscous fingering instability-based, lithography-less, spontaneous, and scalable process for fabricating 3D patterns like a nature-inspired honeycomb structure with ultra-high aspect ratio walls. Rich experimental data on volatile fluids shaping in uniport and multiport lifted Hele-Shaw cells (ULHSC and MLHSC) obtained through extensive experiments is represented on a non-dimensional phase plot. The phase plot with five orders of magnitude variation of non-dimensional numbers on each axis demarcates the regions of several newly observed phenomena: ‘No retention’, ’Bridge breaking’, and ‘wall formation’ with ‘stable’ and ‘unstable’ evolution. A new non-dimensional ratio of the velocity of evaporating static interface vs. lifting velocity is proposed for the same. This work establishes a solid foundation with valuable insights for scalable manufacturing of devices useful for application in biomedical and other domains.
Enhancing the Adsorption Performance of Chitosan to Phenol Derivatives through Hydrophobic Modification: Kinetics, Equilibrium, and Mechanisms

Published: December 2022

Abstract
Adsorption is effective methods to remove trace organic pollutants in water, and the development of cheap and efficient adsorption materials is essential to the real application of this technique. In this study, chitosan, a natural aminopolysaccharide, was grafted with palmityl chloride using an acylation procedure to improve its hydrophobicity and adsorption capacity to hydrophobic organic contaminants. A hydrophobically-modified chitosan (HMC2) was characterized using Fourier transform infrared spectroscopy (FTIR), and then was tested to adsorb phenolic pollutants from water. The batch adsorption experiments were employed to investigate the adsorption equilibrium and kinetics of 4-nonylphenol(4-NP), α-naphthol(Nap), 4-chlorophenol(4-CP) and phenol(Phe) on HMC2 and chitosan. The effect of temperature, salt concentration, and pH on adsorption was studied for the understanding of adsorption processes. Moreover, a linear free energy relationship approach and FTIR technique were used to identify the predominant adsorption mechanisms. The obtained results showed that the modified chitosan had higher adsorption capacity to 4-NP, Nap, 4-CP and Phe than the unmodified one. The adsorption kinetics of 4-NP, Nap and 4-CP on chitosan and HMC2 were found to be well fitted by the first-order kinetic model. The adsorption isotherms of 4-NP, Nap, 4-CP and Phe on HMC2 conformed to the linear or Freundlich models. The pH range from 5.6-8.5 appeared to have non-significant effect on the adsorption capacity of HMC2. However, the increasing salt concentration was found to favor the adsorption. The adsorption enthalpy changes (ΔH0) for 4-NP, Nap and CP on HMC2 varied from -3.82 to -0.44 kJ/mol, and the adsorption entropy changes (ΔS0) changed from 21.7 to 85.9 J/(mol·K). When the logarithms of the distribution constant (logKd) were correlated with the logarithms of the octanol-water partition coefficient (logKow), a good linear relationship was observed:logKd=1.451·logKow - 4.893 (r2=0.999). Thus, the hydrophobic interaction was proposed as a predominant mechanism for adsorption of nonionized 4-NP, Nap, 4-CP, and Phe on HMC2, which was further confirmed by the FTIR data. This study may provide guidance for tailoring high-performance chitosan to selectively remove organic pollutants in water.
Resistir, alinear o adherir. Los centros educativos y las familias ante las BigTech y sus plataformas educativas digitales

Published: December 2022

La pandemia ha evidenciado la capacidad de determinados proveedores de servicios tecnológicos, especialmente de plataformas digitales, para adaptarse y responder rápidamente a las supuestas necesidades del sistema educativo.
En este artículo identificamos algunas de las tensiones que la intensificación en la adopción de plataformas digitales educativas ha evidenciado en el ámbito escolar y familiar. A partir de un diseño metodológico mixto, que incluyó la realización de seis entrevistas en profundidad a directores/as de centros educativos y la aplicación de una encuesta a 2112 familias, se analizaron los posicionamientos de la comunidad escolar y de las familias sobre el uso de plataformas educativas digitales en centros educativos públicos de Cataluña.
Los resultados revelan conflictos vinculados a la “necesidad” de adaptarse a una realidad post-digital en la que adoptar posturas críticas -minoritarias- se percibe como una amenaza para el libre desarrollo de la práctica profesional y para el acceso a la educación en condiciones de igualdad. Al mismo tiempo, los resultados subrayan el papel del profesorado en la profundización de posturas críticas y reflexivas que posibiliten, también para el alumnado, el cuestionamiento de formas naturalizadas de trabajo e interacción.
Pharmacological Treatment of Alcohol use Disorder in Patients with
Psychotic Disorders: A Systematic Review
Authors: Rosenstand Niels Jørgen , Nielsen Anette Søgaard , Skøt Lotte , Anhøj Simon , Nielsen Dorthe Grüner , Højlund Mikkel , Mellentin Angelina Isabella 
Published: December 2022

Background:
Patients with psychotic disorders (PD) often have comorbid alcohol use disorder
(AUD), which is typically treated pharmacologically. Up till now, no systematic review has examined
the effectiveness and safety of AUD treatment in PD patients.

Objectives:
This study aimed to systematically review the literature on (1) the effects of pharmacological
treatments for AUD on drinking outcomes, (2) the side effects of the drugs, and (3) the effects of
polypharmacy in patients with comorbid AUD and PD.

Methods:
Bibliographic searches were conducted in MEDLINE, Embase, Cochrane Central Register
of Controlled Trials, and PsycINFO. At least two reviewers extracted the data, assessed the risk of bias,
and performed the qualitative synthesis of the collected evidence.

Results:
Twelve eligible studies were identified, half being randomized controlled trials (RCTs).
Three studies examined disulfiram, nine naltrexone, two acamprosate, and one nalmefene by comparing
the effects of treatment to placebo, baseline, or pharmacological agents. Disulfiram and naltrexone
were shown to reduce alcohol intake. Regarding acamprosate, the findings were mixed. Nalmefene
decreased alcohol intake. All pharmacological agents appeared safe to use as AUD monotherapy, but
cardiac events were reported when combining naltrexone and disulfiram. Nine studies had a high risk
of bias, and three had some other concerns.

Conclusion:
The studies provide tentative support for the use of naltrexone and disulfiram in this population,
although combinations of pharmacological AUD treatments and other polypharmacy remain
unexplored. The studies had high adherence rates that are hardly replicable in real-world settings.
Thus, the findings should be confirmed in larger high quality efficacy and effectiveness RCTs with
longer follow-ups.
How to Collect and Interpret Medical Pictures Captured in Highly
Challenging Environments that Range from Nanoscale to Hyperspectral
Imaging

Published: December 2022

Abstract:
Digital well-being records are multimodal and high-dimensional (HD). Better theradiagnostics stem from new computationally thorough and edgy technologies, i.e., hyperspectral (HSI) imaging,
super-resolution, and nanoimaging, but advance mess data portrayal and retrieval. A patient's state
involves multiple signals, medical imaging (MI) modalities, clinical variables, dialogs between clinicians and patients, metadata, genome sequencing, and signals from wearables. Patients' high volume,
personalized data amassed over time have advanced artificial intelligence (AI) models for higherprecision inferences, prognosis, and tracking. AI promises are undeniable, but with slow spreading and
adoption, given partly unstable AI model performance after real-world use. The HD data is a ratelimiting factor for AI algorithms generalizing real-world scenarios. This paper studies many health
data challenges to robust AI models' growth, aka the dimensionality curse (DC). This paper overviews
DC in the MIs' context, tackles the negative out-of-sample influence and stresses important worries for
algorithm designers. It is tricky to choose an AI platform and analyze hardships. Automating complex
tasks requires more examination. Not all MI problems need automation via DL. AI developers spend
most time refining algorithms, and quality data are crucial. Noisy and incomplete data limits AI, requiring time to handle control, integration, and analyses. AI demands data mixing skills absent in regular systems, requiring hardware/software speed and flexible storage. A partner or service can fulfill
anomaly detection, predictive analysis, and ensemble modeling.

Authors: Nitiéma Pascal 
Published: December 2022

BackgroundArtificial intelligence (AI) is being increasingly adopted in the health care industry for administrative tasks, patient care operations, and medical research.ObjectiveWe aimed to examine health care workers’ opinions about the adoption and implementation of AI-powered technology in the health care industry.MethodsData were comments about AI posted on a web-based forum by 905 health care professionals from at least 77 countries, from May 2013 to October 2021. Structural topic modeling was used to identify the topics of discussion, and hierarchical clustering was performed to determine how these topics cluster into different groups.ResultsOverall, 12 topics were identified from the collected comments. These comments clustered into 2 groups: impact of AI on health care system and practice and AI as a tool for disease screening, diagnosis, and treatment. Topics associated with negative sentiments included concerns about AI replacing human workers, impact of AI on traditional medical diagnostic procedures (ie, patient history and physical examination), accuracy of the algorithm, and entry of IT companies into the health care industry. Concerns about the legal liability for using AI in treating patients were also discussed. Positive topics about AI included the opportunity offered by the technology for improving the accuracy of image-based diagnosis and for enhancing personalized medicine.ConclusionsThe adoption and implementation of AI applications in the health care industry are eliciting both enthusiasm and concerns about patient care quality and the future of health care professions. The successful implementation of AI-powered technologies requires the involvement of all stakeholders, including patients, health care organization workers, health insurance companies, and government regulatory agencies.
