Актуальность исследования обусловлена необходимостью разработки новых методик получения сырья из алюминиевого лома. Данное направление при применении различных интенсифицирующих воздействий позволяет реализовать процесс синтеза сырья из металлолома в ресурсосберегающем режиме, минимизирующем объемы затрат на подготовку исходного сырья, последующие переработку и производство. Цель: изучить физико-химические закономерности процесса переработки алюминиевых отходов в поле ультразвука в кислотной среде, предложить механизм этого процесса и на основании установленных закономерностей и предложенного механизма разработать методику переработки алюминиевых отходов с получением востребованных в промышленности продуктов реакции. Объекты: образцы алюминиевых отходов в виде пластинок и стружки. Методы: волюмометрия, сонохимический синтез, оценка и анализ кинетических кривых процесса при разных температурах, рентгенофазовый анализ. Результаты. Проведен анализ кинетических кривых, рассчитаны константы скоростей процесса при различных температурах, определён порядок химической реакции. По рассчитанной энергии активации процесса дана характеристика кинетической области процесса. Согласно полученным данным, воздействие на систему ультразвуком способствовало увеличению скорости химического процесса на 90 % при 303 К; на 5 % при 313 К. Сам процесс начинался в течение 10…30 секунд и завершался в течение нескольких минут, что подтверждает возможность переработки алюминиевых отходов с помощью кислотных растворов при невысоких температурах. Полученный водород можно использовать в водородной энергетике, поскольку он является единственным газообразным продуктом реакции, что снимает необходимость в его очистке перед транспортировкой. Синтезированный в ходе реакции раствор хлорида алюминия можно использовать при очистке сточных вод, обработке древесины, производстве антиперспирантов, а также перевести в фосфат или гидроксид алюминия и использовать в керамической промышленности.
Fractals and music

Published: November 2022

Many natural phenomena we find in our surroundings, are fractals. Studying and learning about fractals in classrooms is always a challenge for both teachers and students. We here show that the sound of musical instruments can be used as a good resource in the laboratory to study fractals. Measurement of fractal dimension which indicates how much fractal content is there, is always uncomfortable, because of the size of the objects like coastlines and mountains. A simple fractal source is always desirable in laboratories. Music serves to be a very simple and effective source for fractal dimension measurement. In this paper, we are suggesting that music which has an inherent fractal nature can be used as an object in classrooms to measure fractal dimensions. To find the fractal dimension we used the box-counting method. We studied the sound produced by different stringed instruments and some common noises. For good musical sound, the fractal dimension obtained is around 1.6882.

Published: November 2022

Summary
Computational fluid dynamics (CFD) and experimental studies were applied to evaluate a novel turbulence-based scaleup method capable of matching systems with different geometries. This study specializes in determining optimum agitation speed in laboratory reactors used for flow assurance studies to match the hydrodynamic condition of three-phase flow in pipelines. Turbulence parameters were calculated using CFD for a laboratory-scale reactor at various mixing speeds and a real large-scale pipe. The calculations for the pipeline matched the reactor working at 590 rev/min, identifying the ideal mixing speed, the speed at which the reactor is closest to the pipeline regarding the fluid mixing and turbulence. This finding was compared with flow regime and mixing data of both geometries in the literature and finally confirmed by experiments. It was empirically proved that a turbulence analysis based on geometry-independent parameters could link systems’ mixing conditions with different scales and geometries.
An Efficient and Straightforward Procedure for Rapid Investigation of Reservoir Compartmentalization by Fourier Transform Infrared Spectroscopy of Asphaltenes

Published: November 2022

Summary
Reservoir compartmentalization is an essential phenomenon in the different life cycles of oilfield production. This concept is crucial for the economic assessment of field development plans because it influences future decisions and designs. Hence, early and fast identification of reservoir compartmentalization is highly appreciated in the oil industry. The routine techniques based on the light-end fraction of crude oil [e.g., gas chromatography (GC) fingerprinting] are relatively time-consuming, high-cost, and sometimes affected by secondary processes. The suggestion of an efficient, straightforward, and rapid technique for obtaining the reservoir architecture, especially in giant and supergiant fields, is an acceptable attempt in the oil industry. Although the concentration of asphaltenes shows a gradient in the reservoir, the chemical composition of these compounds is constant in connected and equilibrated reservoirs. Hence, investigation of the chemical composition of asphaltenes with a precise method for revealing subtle differences comprises the underlying of every efficient method in reservoir continuity assessment. Here, the application of the relative root-mean-square deviation (RMSD) technique on the Fourier transform infrared (FTIR) data was used to compare the structural characteristics of asphaltenes in two case studies (i.e., Ahwaz and Shadegan oil fields) from the Dezful Embayment, southwest Iran. The 12 highest difference characteristic peak ratios were determined in the studied sample suit from the calculated variations in 5 replicates of a sample. The comparison between samples was performed based on these peak ratios, and the RMSD method was used to compare the studied samples. The samples with RMSD values higher than the defined threshold were considered samples with different fingerprints, and these wells will not be communicated during production. Results showed that the Ahwaz and Shadegan fields were subjected to reservoir compartmentalization in the Bangestan reservoir. At least three compartmentalized regions have occurred in the Bangestan reservoir of the Ahwaz field, and two distinct zones are observed in this reservoir from the Shadegan field. The pressure/volume/temperature (PVT) data (i.e., fluid property and composition) and repeat formation tester (RFT) measurements confirmed that these proposed regions in the Ahwaz field are distinct and will not be communicated during production. The FTIR results in the Shadegan field were completely corroborated by PVT and RFT results and indicated two distinct zones with no flow communication during production in the Bangestan reservoir. The obtained results showed that the suggested procedure is robust, trustworthy, simple, rapid, and cost-effective for investigating reservoir compartmentalization.

Authors: Behrenbruch Peter , Ashena Rahman 
Published: November 2022

Summary
This paper gives several examples of rock compressibility laboratory testing results, and how these data are prepared as input to reservoir simulation or other applications. The final selection of rock compressibility is also compared with standard industry correlations to gauge the accuracy of such correlations in case laboratory results are not available.
A review of rock compressibility formulations and associated models is given first, including the treatment of various rock types. Second, laboratory experiments are described using the rock compressibility system (RCS) and the compressibility measurement system (CMS), and a comparison of the two is given. Based on a literature review, there is apparently no available procedure or workflow for analyzing raw compressibility data to derive meaningful interpretations, which are furthermore used in various applications. Taking the results from laboratory testing, a workflow procedure for deriving compressibility input data is outlined in detail, including the choice of ancillary data, for example, Poisson’s ratio. The workflow includes finding regression-based functions of measured pore volumes (PVs), obtaining their derivatives, and finding optimal solutions following a statistical analysis. The demonstrated workflow has been developed to be able to treat alternative laboratory experiments and results for a variety of rock types in carbonates, with regression-based compressibility correlations found. This allows safeguard against possible shortcomings and pitfalls, which are also demonstrated.
Having been implemented on real case studies, the formulation presented has been computerized, allowing for ease of data handling, comparative study, and consistency.

Authors: Yu Mingyi , Li Fei , Lu Xiaoxiao , Zhao Shaozhen 
Published: November 2022

AbstractBackground: Neurotrophic Keratopathy (NK) is an orphan disease caused by reduction or absence of corneal innervation. Among the numerous etiologies of NK, central nervous system injuries affecting normal trigeminal nerve function is especially rare and serious, making the management of thses cases very challenging. Cenegermin (Oxervate, Dompè Farmaceutici, Milan, Italy) is a new recombinant human nerve growth factor approved for the treatment of stage 2 or 3 NK. Here, we describe the long-term outcome of NK patients associated with central nervous system injury treated with cenegermin. Method: Retrospective, consecutive, observational case series study. Describe and compare three cases of neurotrophic keratopathy (NK) arisng after central nervous system injury in different regions and treated with cenegermin eye drops. Restoration of corneal epithelial defects, corneal sensation and reinnervation evaluated by IVCM were documented in this study. Results: After 1 to 2 course of cenegermin therapy, a successful epithelial restoration and an increase in corneal sensation were achieved in all patients. Regeneration of subbasal nerve plexus was maintained during and after 1 year of cenegermin therapy, demonstrated by in vivo confocal microscopy (IVCM). One patient underwent conjunctival flap surgery 12 months after cenegermin treatment due to recurrence of NK. Conclusion: Neurotrophic keratitis secondary to central nervous system injury deserves much more recognition and cenegermin represent valuable in the management of NK, especially in terms of subbasal corneal nerve regeneration.
Neurotypicals with Higher Autistic Traits have Delayed Visual Processing of an Approaching Life-size Avatar’s gait: An Event-Related Potentials Study
Authors: Inokuchi Ryo , Ichikawa Hiroko , Yamamoto Masataka , Takemura Hiroshi 
Published: November 2022

Abstract
We investigated the association between autistic traits in neurotypical adults and the visual processing of an approaching life-size avatar’s gait. Autism spectrum disorder (ASD) is a neurodevelopmental disorder and is reported to be related to difficulties in visual processing of human motion, such as biological motion and gestures. It has been reported that neurotypical adults with higher autistic traits were clumsier than those with lower autistic traits when passing by others. To clarify such atypical visual motion processing along with higher autistic traits in daily life, we analyzed the Subthreshold Autistism Trait Questionanaire (SATQ) score, a 24-item self-reported scale of ASD and event-related potentials (ERPs), for 26 neurotypical adults, in response to walking motion while passing the avatar. Videos of a walking life-sized virtual avatar approaching and retreating were presented as visual stimuli. The association between participants' scores of autistic traits and the latencies and amplitudes of ERPs was examined. ERP components (N170 and P200) were identified in the occipito-temporal region. As a result, adults with higher autistic traits had longer latencies and smaller amplitudes of P200 for the approaching avatar in the occipito-temporal region than those with lower autistic traits. These findings indicate that adults with higher autistic traits have delayed and less sensitive visual processing of the approaching avatar. It suggests that while passing by another person, these individulas have atypical visual processing of another person’s approach. This study may contribute to elucidating autistic traits from the perspective of visual processing in an environment mimicking daily life.
Particle-Environment Interactions In Arbitrary Dimensions: A Unifying Analytic Framework To Model Diffusion With Inert Spatial Heterogeneities
Authors: Sarvaharnan Seeralan , Giuggioli Luca 
Published: November 2022

Abstract
Interactions between moving entities and spatial disorder have a fundamental impact on
the transport properties of natural and artificial systems. The unprecedented resolution brought by modern technologies in particle or individual tracking and in recording of the spatial environment demand more advanced quantitative techniques to interpret how movement is affected by spatial heterogeneities. Here we tackle this challenge by developing a mathematical framework to model inert particle-environment interactions in domains of arbitrary shape and dimensions. By constructing a fully analytic formalism we predict how the spatio-temporal dynamics of randomly moving entities change in the presence of reflecting or partially reflecting obstacles, regions of increased or decreased diffusivity, one-way gates, open partitions, reversible traps as well as long range connections to far away areas. To demonstrate the vast applicability of our techniques we employ them to study three examples spanning different spatial and temporal scales in physiology, ecology and molecular biology.
Embryo growth alteration and oxidative stress responses in germinating Cucurbita pepo seeds exposed to cadmium and copper toxicity
Authors: ACILA SMAIL , Derouiche Samir , Allioui Nora 
Published: November 2022

Abstract

To assess the impact of heavy metals (cadmium, copper) on the germination, metabolism and growth of zucchini seedlings (Cucurbita pepo L.), a test was conducted 'in vitro' on the germination and growth of zucchini seedlings, subjected to two concentrations (100 and 200 μM) of CdCl2 and CuCl2. The germination parameters, as well as the biochemical and phytochemical properties of the embryonic axes of the seedlings, were studied. The obtained results showed that the seed vigor index (SVI) of zucchini seeds recorded a significant and remarkable decrease under the effect of Cd. A significant decrease was also noted in the length and the dry weight of the embryonic axes of the young seedlings, which differed according to the type of metal. No significant increases in malondialdehyde (MDA) and H2O2 content, or in catalase (CAT) activity were noted at the tested concentrations of the Cd and Cu salt, but very significant decreases in superoxide dismutase (SOD) activity of embryonic axis tissues were observed. Glutathione S-transferase (GST) activity exhibited a significant increase at 200 μM CdCl2 whereas the glutathione (GSH) content decreased with increasing metal concentrations (Cd, Cu) of the medium. An increase in total phenol content and antioxidant activity was recorded at 200 μM of CuCl2. Based on the obtained results, we can conclude that heavy metals (Cd, Cu) reduce the germination efficiency of zucchini seeds and cause metabolic alterations of embryonic tissue cells, and the response of zucchini seedlings to metal stress depends on the type of metal and its concentration.

Abstract
Electrochemical CO2 reduction (CO2R) is an approach to closing the carbon cycle for chemical synthesis. To date, the field has focused on the electrolysis of ambient pressure CO2. However, industrial CO2 is pressurized – in capture, transport and storage – and is often in dissolved form. Here, we discover that pressurization up to 50 bar steers CO2R pathways toward formate, as universally exemplified on common CO2R catalysts. By developing operando methods compatible with high pressures, including quantitative operando Raman spectroscopy, we ascribe the pronounced formate selectivity to the higher CO2* coverages and lower hydronium ion concentrations on the cathode surface. The interplay of theory and experiments validates the mechanism, and guides us to functionalize the surface of a Cu cathode with a hydronium-repelling layer to further the pressure-mediated selectivity effect. This work illustrates the value of industrial CO2 sources as the starting feedstock for sustainable chemical synthesis.

Published: November 2022

Abstract
Interpreting and tracking finger motion in free space are important for human communication in the reality–virtuality continuum. End-user form-factor-free sensors integrated with neuromorphic computing capabilities can expedite the implementation of human–machine interfaces with accurate finger motion recognition. We introduce and design an ultra-flexible TiO2 artificial synapse array and organic proximity sensor conformably attachable to the finger skin surface for real-time finger motion recognition in free space. Ultra-flexible synaptic device and sensor exhibit well-defined synaptic and light-responsive electrical properties, along with mechanical robustness, and the synapse–sensor integration enables optical–electrical signal conversion. Accordingly, various finger motions for time-resolved digit patterns following a Eulerian trail in free space can be learned and recognized with up to ~95 % accuracy for different individuals at varying strains and repeated cycles. Our proposal may contribute to the development of human–machine interaction wearables for extended reality.

Published: November 2022

Abstract
Hepatic ischemia-reperfusion (I/R) injury, a common clinical complication of liver transplantation, gravely affects patient prognosis. Krüppel-like factors (KLFs) are a family of C2/H2 zinc finger DNA-binding proteins. KLF6, a member of the KLF family proteins, plays crucial roles in proliferation, metabolism, inflammation and injury responses; however, its role in HIR largely remains unclear. Herein, we found that KLF6 expression was significantly up-regulated in mice and hepatocytes after I/R injury. Subsequently, mice were subjected to I/R after tail vein injection of shKLF6- and KLF6-overexpressing adenovirus. KLF6 deficiency markedly aggravated liver damage and cell apoptosis along with the activation of hepatic inflammatory responses, whereas hepatic overexpression of KLF6 in mice showed opposite effects. Furthermore, we knocked out or overexpressed KLF6 in AML12 cells, and then exposed to hypoxia-reoxygenation challenge. KLF6 knockout significantly reduced cell viability, and increased hepatocyte inflammation, apoptosis, and ROS, whereas overexpression of KLF6 showed the opposite effects. Mechanistically, KLF6 inhibited the overactivation of autophagy at the initial stage, and the regulatory effect of KLF6 on I/R injury was autophagy-dependent. CHIP-qPCR and luciferase reporter gene assays confirmed that KLF6 was bound to the promoter region of Beclin1 and inhibited its transcription. Moreover, KLF6 activated the mTOR/ULK1 pathway. Finally, we retrospectively analyzed the clinical data of liver transplantation patients and observed significant associations between KLF6 expression and liver function after liver transplantation. In summary, KLF6 inhibited the overactivation of autophagy by transcriptional regulation of Beclin1 and activation of the mTOR/ULK1 pathway, thereby playing a protective role against hepatic I/R injury. KLF6 is expected to serve as a biomarker to predict the severity of I/R injury after liver transplantation.
