The role of acid–base interactions in the pitting corrosion of aluminum: a review
Authors: Petrunin Maxim Andreevich , Maksaeva Liudmila Borisovna , Yurasova Tatyana Aleksandrovna 
Published: July 2023

Abstract
The review describes an electrode kinetic model of aluminum pitting nucleation taking into account the charge of the metal surface, the adsorption of chloride ions on the oxide surface, their penetration through the oxide film with the help of oxygen vacancies, and the dissolution of the underlying substrate with the initiation of pitting corrosion at the metal/oxide interface. It is shown that the critical pitting potential is a function of the potential of a thin layer of aluminum surface covered by oxide and the value of the pitting potential of a binary surface alloying is related to the isoelectric point of the alloying element oxide in the binary alloy. An electrode kinetic model of pitting initiation is described, which was used to explain the effect of surface alloying on the pitting initiation on binary alloys. A method for changing the surface charge by forming foreign surface organosilicon nanolayers bearing both negatively and positively charged groups was proposed. It has been established that four characteristics (q, Ψ
1-potential, E
pit and the tendency of aluminum to depassivate) depend on the nature of ion-exchange groups, the degree of their acid dissociation, and the ion-chemical interaction with activator ions.
Structural behavior of concrete filled double-skin PVC tubular columns confined by plain PVC sockets
Authors: Abbas Jinan Laftah 
Published: July 2023

Abstract
The behavior of concrete-filled double-skin poly vinyl chloride (PVC) tubular columns confined by plain PVC sockets is studied in this research. The plastic pipes have been used with concrete as columns. PVC has several advantages as it is inexpensive, light weight for construction, and decrease in the time taken for construction. Thus it can be used as an alternative to metal in various applications in which the maintenance cost is increased and the corrosion is reduced. This study is an experimental work on four groups of composite hollow PVC columns, each group containing three different samples. The effects of several parameters are studied, including slenderness ratio, compactness ratio, compressive strength, and confinement ratio. The experimental results show that stiffness, strength, as well as the ductility of composite columns of different loadings were considerably influenced by all these parameters. An increase in loading carrying capacity by about 40.4% was noticed as slenderness ratio decreased from 20 to 12 and about 21.1% as compactness ratio decreased from 50 to 25. Besides, the rate of increase in load capacity was about 96.6% as compressive strength increased from 33 to 54 MPa. For the case of variation of confinement ratio from 25 to 75%, the increase in the axial load capacity was about 56.7%. The main benefit of this type of column is the interaction between PVC tube and concrete. Besides, restriction of concrete by tube results in the delay of local buckling so that the concrete strength is enlarged by the effect of confining provided by the tube.

Knockdown of circ_0113656 assuages oxidized low-density lipoprotein-induced vascular smooth muscle cell injury through the miR-188-3p/IGF2 pathway
Authors: Yang Ming , Luo Jun , Zhang Shuhua , Huang Qing , Cao Qianqiang 
Published: July 2023

Abstract
Circular RNA (circRNA) is involved in the pathogenesis of atherosclerosis (AS). The present work analyzed the RNA expression of circ_0113656, microRNA-188-3p (miR-188-3p), and insulin-like growth factor 2 (IGF2) by quantitative real-time polymerase chain reaction. The protein expression of proliferating cell nuclear antigen (PCNA), matrix metalloprotein 2 (MMP2), and IGF2 was detected by Western blotting. Cell viability, proliferation, invasion, and migration were analyzed using the cell counting kit-8, 5-ethynyl-2′-deoxyuridine, transwell invasion, and wound-healing assays, respectively. The interactions among circ_0113656, miR-188-3p, and IGF2 were identified by dual-luciferase reporter assay and RNA immunoprecipitation assay. The results showed that circ_0113656 and IGF2 expression were significantly upregulated, while miR-188-3p was downregulated in the blood of AS patients and oxidized low-density lipoprotein (ox-LDL)-treated HVSMCs in comparison with controls. The ox-LDL treatment induced HVSMC proliferation, migration, and invasion accompanied by increases in PCNA and MMP2 expression; however, these effects were attenuated after circ_0113656 knockdown. Circ_0113656 acted as a miR-188-3p sponge and it regulated ox-LDL-induced HVSMC disorders by binding to miR-188-3p. Besides, the regulation of miR-188-3p in ox-LDL-induced HVSMC injury involved IGF2. Further, the depletion of circ_0113656 inhibited IGF2 expression by interacting with miR-188-3p. Thus, the circ_0113656/miR-188-3p/IGF2 axis may mediate ox-LDL-induced HVSMC disorders in AS, providing a new therapeutic strategy for AS.
Optimization of cutting parameters by thrust force and time for drilling of aluminum 2024 T351
Authors: Turgut Yunus Zubeyir , Ozsoy Murat 
Published: July 2023

Abstract
In this study, the cutting parameters were optimized according to the thrust force and operation time in the drilling of Al 2024 T351 alloy, which is preferred in the aerospace industry and therefore subjected to thousands of drilling processes with liquid cooling. Cutting speed (70, 90, and 110 m min−1) and feed rate (0.08, 0.1, and 0.12 mm tooth−1) were considered cutting parameters. Experiments were performed three tool types (HSS, HSSE-Co5, HSSE-Co5 TiAlN coated). Taksan TMC-700 V CNC vertical machining center with FANUC control panel was used for drilling, and ESIT AX3 load cell and NI cDAQ-9188, data acquisition system, were used for data collection. Signal noise was reduced by applying the exponential smoothing method to all force data obtained in the experiments. The maximum forces in the machining direction (z-axis) were determined for each hole. The time was calculated during the computer aided manufacturing process. Response surface optimizations, variance analyses (ANOVA), and regression analyses were performed using these determined maximum thrust forces and measured time.

Significance of heat and mass transport in peristaltic flow of Jeffrey material subject to chemical reaction and radiation phenomenon through a tapered channel
Authors: Ravikumar Seelam , Ijaz Khan Muhammad , AlQahtani Salman A. , Eldin Sayed M. 
Published: July 2023

Abstract
Using mathematical modeling and computational analysis, this study aims to examine the peristaltic blood flow of a non-Newtonian material in a tapered channel with radiative heat flux and response mechanisms. By utilizing a long-wavelength approximation, ignoring the wave number, and performing under conditions of low Reynolds number, closed form solutions for the velocity, temperature, and concentration fields are achieved. Several governing parameters and their effects on the system were analyzed, and relevant diagrams were provided. Increasing the Biot number, Jeffrey material, and thermal radiation parameter of the heat and mass transfer mechanism increases the velocity profile. When the heat source/sink parameter and the heat transfer Biot number increase, the temperature profile improves. The resultant concentration distributions are enhanced when mass transfer Biot number, heat radiation, and chemical processes are all raised. We observe that the pressure rate decreases in all three pumping zones when the heat transfer Grashof number and heat transfer Biot number rise. This is because the pressure rate is affected by the Grashof number and Biot number of heat transmission. The increase in thermal radiation parameter and heat transfer Biot number results in a slower rate of heat transfer than when Prandtl number and heat source/sink parameter increases. When the Soret number, Schmidt number, Biot number, and heat source/sink parameter are all raised, the mass transfer coefficient also rises. This rate, however, decreases as the heat radiation and chemical reaction parameters rise. The findings presented in this study have interesting implications for other aspects of human physiology. The preponderance of organs are permeable. Furthermore, fluids render the location of natural boundaries uncertain. The presented mathematical model can be used to derive predictions about the behavior of various systems. For the study of cancer treatment in biological systems, a mathematical model that includes nanoparticles, viscosity dissipation, and rotation holds much promise. Model development incorporated Soret–Dufour effects and thermal analysis of the digestive system.

Abstract

Objectives
Acceptance and Commitment Therapy (ACT) is an established treatment for chronic pain. However, it is a form of treatment that have not yet been applied much in the treatment of persistent vulvar pain disorders. This study examines the feasibility and preliminary effects of online ACT for patients with provoked vestibulodynia.

Methods
Women diagnosed with provoked vestibulodynia were assigned randomly either to online ACT or to a waitlist control group. Feasibility was assessed in terms of recruitment potential, treatment credibility, completions rates, retention in trial, and data quality. Participants completed measures of pain with sexual activity, sexual functioning, emotional and relational adjustment, and potential treatment processes before and after treatment.

Results
Of the 111 women who were invited to participate in the study, 44 were included (39.6 % recruitment rate). Thirty seven participants (84.1 %) completed the pre-treatment assessment. Participants who received online ACT rated treatment credibility positively, and completed on average 4.31 (SD=1.60) of the six treatment modules. Of participants, 34 provided post treatment data, giving a trial retention rate of 77 %. Effects of online ACT, as compared to waitlist, were large for pain acceptance and quality of life, medium for anxiety and pain catastrophizing, and small for sexual satisfaction, pain with sexual activity, and relationship adjustment.

Conclusions
With some adjustments to recruitment procedures, a full scale randomized controlled trial of online ACT for provoked vestibulodynia appears feasible.
Design of blood plasma concentrations sensor based on a one-dimensional photonic crystal
Authors: Segovia-Chaves Francis , Beltrán Santiago Santos , Vinck-Posada Herbert 
Published: July 2023

Abstract
This study uses the transfer matrix method to calculate the transmittance spectrum of a one-dimensional photonic crystal (1D-PC). Herein, the crystal is composed of alternating layers of barium titanate ferroelectric and yttrium oxide dielectric. The spatial periodicity of the 1D-PC is broken by a cavity surrounded by thin layers of a critical high-temperature superconductor, which can be used to detect refractive index changes of plasma cells infiltrated into the cavity. The results reflect the existence of a maximum transmittance peak in the telecom region known as a localized mode within the photonic band gap. This study reveals that the localized mode shifts toward longer wavelengths as the operating temperature of the superconductor increases. Additionally, we calculate the sensitivity and quality factor of the localized mode, thereby finding that these quantities increase as the incidence angle increases. The proposed model works in cryogenic temperature environments and may be integrated into biosensor designs.

Published: July 2023

AbstractThe present study aimed to explore the virulence characteristics in 221 Bulgarian nosocomial Stenotrophomonas maltophilia isolates (2011–2022) via screening for the presence of virulence genes, their mutational variability, and the corresponding enzyme activity. PCR amplification, enzymatic assays, whole-genome sequencing (WGS), and biofilm quantification on a polystyrene plate were performed. The incidence of virulence determinants was as follows: stmPr1 (encoding for the major extracellular protease StmPr1) 87.3%, stmPr2 (minor extracellular protease StmPr2) 99.1%, Smlt3773 locus (outer membrane esterase) 98.2%, plcN1 (non-hemolytic phospholipase C) 99.1%, and smf-1 (type-1 fimbriae, biofilm-related gene) 96.4%. The 1621-bp allele of stmPr1 was most frequently found (61.1%), followed by the combined allelic variant (17.6%), stmPr1-negative genotype (12.7%), and 868-bp allele (8.6%). Protease, esterase, and lecithinase activity was observed in 95%, 98.2%, and 17.2% of the isolates, respectively. The WGS-subjected isolates (n = 9) formed two groups. Five isolates possessed only the 1621-bp variant of stmPr1, higher biofilm formation ability (Optical Density at λ = 550 nm (OD550): 1.253–1.789), as well as a low number of mutations in the protease genes and smf-1. Three other isolates had only the 868-bp variant, weaker biofilm production (OD550: 0.788–1.108), and higher number of mutations within these genes. The only weak biofilm producer (OD550 = 0.177) had no stmPr1 alleles. In conclusion, the similar PCR detection rates did not allow differentiation of the isolates. In contrast, WGS permitted stmPr1 alleles-based differentiation. To the best of our knowledge, this is the first Bulgarian study presenting genotypic and phenotypic insights into virulence factors of S. maltophilia isolates.
Raden Saleh dan Restorasi Makam Tahun 1953: Penghormatan Pelukis Bumiputera dan Penguatan Identitas Nasional pada Masa Kekuasaan Soekarno

Published: July 2023

Raden Saleh, the first painter in Java to adopt modern techniques and gain recognition in the Western world during the Dutch colonial era, holds an important place in Indonesian art history. This article examines the life and contributions of Raden Saleh. It explores the restoration of his tomb by President Soekarno as a means to strengthen Indonesia's national identity in the post-independence period. The research utilizes historical methods, including heuristics, source criticism, interpretation, and historiography. The study reveals that the restoration of Raden Saleh's tomb in 1953, under President Soekarno's leadership, aimed to pay homage to Raden Saleh as a prominent figure in Indonesian history and reinforce the Indonesian identity by recognizing the globally renowned indigenous elite. Although Raden Saleh passed away long before Indonesia's independence, and the concept of Indonesia as a nation emerged much later, the government, particularly under President Soekarno and Minister of Education and Culture Mohammad Yamin, believed that the restoration was necessary due to the unsatisfactory condition of the tomb. Additionally, the presence of paintings reflecting indigenous perspectives and occasionally criticizing colonialism influenced the decision to restore the tomb. This research sheds light on the significance of Raden Saleh's legacy in shaping Indonesian art and the efforts to preserve cultural heritage in the nation. Keywords: Culture, Raden Saleh, Restoration, Soekarno

Published: July 2023

The article presents the results of a study of hydrocatalytic processing of two fuel oils in the presence of nanocatalytic systems in the form of oil-soluble precursors based on nickel and zinc. The process was carried out on a pilot plant for hydroprocessing with a flow reactor at a temperature of 440 ℃, a hydrogen pressure of 6 MPa, a feed space velocity of 1.0 s-1, and a hydrogen circulation ratio of 1000 nl/l. The catalyst efficiency was evaluated by changes in the material balance, in hydrogenate desulfurization degree, in 450+ °C fraction conversion degree, and by changes in density and hydrogenate refractive index. An analysis of material balances showed that the addition of nanocatalyst precursors increases the 180–350 °C fraction yield, reduces the coke yield on the fixed layer, which is a layer of ceramic balls, and reduces the 450+ °C residual fraction yield. The gas and gasoline fraction yield is slightly reduced. The analysis of hydrogenates showed a decrease in sulfur content, a decrease in density and refractive index in hydrogenates obtained during the hydroprocessing of raw materials with the addition of nanocatalyst precursors. The optimal concentrations of catalysts were experimentally determined; for nickel, the concentration is 0.1 wt %, and for zinc is 0.15 wt %. A comparison of two methods for the synthesis of nanoscale catalytic systems in raw materials was made: directly in the reaction zone in situ and outside the reaction zone ex situ. The method for synthesizing nanoscale catalytic systems outside the reaction zone makes it possible to further increase the feedstock conversion, the hydrogenate desulfurization degree, and the hydrogenate quality.
