Extensive practical experience in conducting drilling and blasting operations confirms the relevance of the application of the face in the context of explosion quality. However, based on the experience of some quarries, there are doubts about the need to use slaughtering as one of the main factors in increasing the efficiency and, accordingly, abandoning it. The authors of different studies are divided in their opinions. Many researchers claim that the slaughtering contributes to an increase in the useful use of the energy of the explosion, however, under certain conditions, the slaughtering does not affect the efficiency of destruction. The article presents a laboratory study of the effectiveness of the slaughtering during crushing by deflagration method.

The article considers the expediency of changing the methods of ensuring information security of automated process control systems (automated process control systems) of extractive industry enterprises. The analysis of foreign experience allowed us to say that the world's leading economies are preparing for the appearance of a cryptographically relevant quantum computer. Many countries have adopted mandatory and recommendatory documents on the transfer of critical information infrastructure to quantum-secure methods of information protection: quantum key distribution or post-quantum cryptography. Both of these methods have their advantages and disadvantages, which must be taken into account when implementing the automated process control system. The analysis shows that post-quantum cryptography, although it requires less economic costs to improve cryptographic information protection systems, but the cryptographic stability of these algorithms is conditionally secure. The study allows us to conclude that it is advisable to recommend quantum key distribution systems for use in the extractive industry...

Humanism or altruism, patriotism or any other action that would be motivated, if not by love, at least by care and attention, i.e. empathy or consideration for the interests of others, they are really so rare that they are simply difficult to notice, especially in these harsh times. It's as if we forgot about them. And that is the same, as if they are not there. From the point of view of the individual and the protection of his life, there is no difference. Precisely, although quite superfluous, if there are so many homeless, exiles, refugees, in a word, unfortunate, abandoned, forgotten, "invisible" people who no one cares about, isn't it hypocritical to talk about the community's care for the individual. Nevertheless, respecting the individual and some other segments of human existence, certain forms of reality in certain countries show different, new tendencies, which from the author's point of view can be subsumed under "real solutions" of importance for understanding the relevant problem. So, in that whole story, in its ambiguity and complexity, in the multitude of questions that "open up" in connection with it, the central one is recognized - does a person have the right to a dignified death'? Yes, the position of the Spanish legislator is to allow euthanasia, and it is explicitly formulated in Law LO 2/2021. For example, on October 18, 2021, Spain decided to legalize voluntary euthanasia and assisted suicide for people suffering from serious and incurable diseases who want to end their suffering and life. By passing such a law, Spain has become the fourth country in Europe to allow both forms of ending the life of a dying patient. The paper will, therefore, analyze in more detail the specifics of the legal regulation of euthanasia in Spanish law, and briefly provide a comparative analysis of its criminal law regulation in some other European countries that have decided to regulate this sensitive issue in a different or the same way - through its legalization.

Background: Wound infections are one of the most prevalent hospital acquired illnesses and a significant contributor to morbidity. Antibiotic-resistant bacterial infections worsen the condition in developed, developing, and underdeveloped countries. Aim: The purpose of this research was to identify the frequency of various bacterial pathogens and their sensitivity to various kinds of antibiotics in various categories of wound infections in randomly selected Basra City hospitals. Method: Fifty-seven patients with wound infection were involved in this cross sectional study, which was conducted by extracting data from the records of hospital laboratories, where information about bacterial examination of swabs taken by hospital staff from infected wounds and cultured with antibiotic sensitivity test by laboratory staff for treatment purposes. Results and Conclusions: The median age of patients was 38 years, 59.65% of them were males. The most frequent bacteria encountered was Klebsiella pneumonia (24.56%). Single bacterial growth was dominant (86% of cultured bacteria). In antibiotic sensitivity test Gentamycin (7.19%), Ciprofloxacin (5.92%), Amikacin (5.50%), and Tobramycin (5.36%) were the most frequent antibiotics tested, while Cefotaxime, Ceftriaxone, Clarithromycin, and Nalidixic acid were the least used. The highest sensitivity shown by the cultured bacteria was to Tigecycline (92.86%), Lenizoild (90.91%), and Teicoplanin, (80.00%), although they had not been tested widely. While, the antibiotics to which the cultured bacteria did not show any sensitivity were Lomefloxacin (0.00), Ceftriaxone (0.00), and Nalidixic Acid (0.00).

Background: Catheter-related infection (CRI) is a serious complication among hemodialysis patients, associated with significant morbidity and mortality. This study investigated the incidence, predictors, presentation, and complications of CRI. Methods: This single-center, retrospective, observational study enrolled all eligible chronic hemodialysis patients with tunneled central venous catheters inserted between June 2016 and June 2019. Results: Over 3 years, 63 patients (59% men) with a total of 27,395 catheter days were included of these patients. The median age was 68 years (interquartile range [IQR]: 58,76), and median hemodialysis duration was 62 months (IQR: 16,101). A total of 30 episodes of clinical CRI occurred, resulting in an overall incidence rate of 1.1 per 1,000 catheter days. CRI was significantly associated with baseline anemia (adjusted hazard ratio [AHR]=3.29; 95% confidence interval [CI], 1.42–7.64; P=0.006) and the use of the femoral vein as opposed to internal jugular vein (AHR=3.23; 95% CI, 1.29–8.06; P=0.012). The incidence of catheter-related bacteremia was 0.91 per 1,000 catheter days, and the most commonly isolated organism was Staphylococcus aureus (26%). Recurrent infection developed in 9/27 (33.3%) episodes and was lower among catheter salvage with antibiotic lock and catheter removal compared to catheter salvage alone. Conclusions: Anemia and the use of the femoral instead of the internal jugular vein are associated with a higher incidence of CRI. Catheter-related blood stream infection was associated with increased mortality, recurrence rate, and resource utilization. Along with systemic antibiotics, catheter management such as catheter removal or antibiotic lock use may help reduce the recurrence rate.

Embracing life's challenges: Developing a tool for assessing resilient mindset in second wave positive Psychology
Authors: Arslan Gökmen , Wong Paul
Published: July 2023

The purpose of this study is to develop and validate the Resilient Mindset Scale (RMS), a brief tool designed to measure resilient mindset among Turkish individuals. Additionally, the study aims to explore the relationship between resilient mindset and mental well-being among adolescents and young adults, providing further evidence in this domain. The exploratory factor analysis, conducted with a sample of 327 participants, revealed that the RMS has a unidimensional structure consisting of six items that effectively measure core indicators of a resilient mindset. Subsequent confirmatory factor analysis, conducted with a sample of 338 participants, confirmed the one-factor structure, demonstrating a good-data model fit with strong factor loadings and internal reliability estimates. Further analyses demonstrated moderate to strong correlations between resilient mindset and mental well-being indicators. Moreover, the latent variables path model revealed that the measurement model had a moderate to strong predictive effect on positive academic functioning, psychological well-being, and psychological distress. These findings establish the psychometric reliability and validity of the RMS as a measurement tool for assessing a resilient mindset among adolescents and young adults. Mental health providers can integrate the concept of a resilient mindset into therapeutic approaches and interventions to foster resilience and enhance mental well-being.

Published: July 2023

Molybdenum mineralization in the Eastern Sayan is represented by the stockwork, vein, and skarn types. The article is devoted to molybdenum ore occurrences of the Dzhetsky ore cluster of the Sisim-Divnogorsk minerogenic zone, that are characterized by the stockwork type mineralization. The Dzhetsky ore cluster is located 160 km northeast of Abakan and 150 km south of Krasnoyarsk. The study included investigations of the host rocks, ores, and ore-accompanying metasomatic alterations; their mineral assemblages; and the morphological types, relationships, and spatial distribution of the ore segregations. It has been demonstrated that the alteration-mineralization zonality of the Teploe 2 and Intrusivnoe molybdenum prospects of the Dzhetsky ore cluster is represented by the propylite type metasomatic alterations that are superimposed in the central segments of the ore occurrences by veinlet silicification bearing copper-molybdenum mineralization.
Phylogenesis of gold in polymetallic volcanogenic-sedimentary massive sulfide ores
Authors: Motov Andrey , Sobolev Alexander
Published: July 2023

The Au concentrational level of the ores of polymetallic volcanogenic-sedimentary massive sulfide deposits is predetermined by the geodynamic setting of their formation. The ores formed in a mid-ocean ridge setting are characterized by low Au grades. The ores formed under the island arc conditions possess higher Au contents. In the course of the further existence of the ore deposit, its ores experience repeated external influences: underwater halmyrolysis, thermal and dynamic metamorphism, hydrothermal-metasomatic transformations, and exogenous oxidation. These processes lead to the transfer of gold from a micro- or nano-sized form in the sulfides to the free form and to redistribution of Au over the ore field of the deposit. The heterogeneity of the ores in terms of the Au content and existence forms must be taken into account when preparing a feasibility study. The work is intended for geologists conducting mining and geological modeling, designing techniques for the ore extraction, and proposing ore processing technologies.

Authors: Larché Nicolas , Leballeur Charles , Diler Erwan , Thierry Dominique
Published: July 2023

The corrosion risk for stainless steel components is not the same in all seawaters, with more failures generally reported in tropical seas. In this study, the influence of biofilm on electrochemical behavior and corrosion resistance of passive films of high-grade alloys was studied in different seawaters, including temperate seawater (France-Brest, North Atlantic Ocean), tropical seawater (Malaysia-Kelatan, Meridional China Sea), and intermediate conditions in terms of temperature (Brazil-Arraial do Cabo, South Atlantic Ocean). The stabilized open-circuit potentials and the polarization behavior of high-grade stainless steels were measured as a function of temperature in all of the tested field marine stations, providing quantified data and direct comparison of the biofilm-enhanced corrosion risks. Significant differences were measured in tropical and in temperate seawaters in heated conditions. Above 37°C, the biofilm activity was much more pronounced in tropical seawater compared to Atlantic Ocean sites, leading to much higher localized corrosion risk. Crevice corrosion of eight high-grades passive alloys was also studied with the use of crevice formers specifically developed for tube geometries. Duplex UNS S32205, superduplex UNS S32750, hyperduplex UNS S33207 and S32707, and 6Mo stainless steels UNS S31266 have been evaluated together with Ni-based alloys UNS N06845 and N06625. In the more severe conditions, the high-grade alloys UNS S32707 and the 6%Mo UNS S31266, both with pitting resistant equivalent number (PREN) around 50, showed better performance than commonly used superduplex UNS S32750 and UNS S39274 (PREN 40). The corrosion results are discussed regarding the monitored biofilm-induced depolarization measured in the different test conditions.

THE NARRATOR IN ALLEYS OF MEMORY
Authors: Fernandes de Oliveira Aciomar
Published: July 2023

Literature, as an instrument for denouncing reality, is extremely relevant because it allows subjects to reflect on inequalities, discrimination, prejudice existing in our society, and not just an entertainment tool. Conceição Evaristo, being a woman and black, finds in fiction a refuge and, at the same time, a way of showing how the characteristics of a past of pain and suffering reverberate in the present, contributing to exacerbate the social exclusion of black men and women. In this sense, the aim of this article is to discuss the identity construction present in the book Alleys of Memory, by the aforementioned author, based on the analysis of the narrator and the correlation between writing and life present in Evaristo’s text, which she calls escrivivência. To do so, we followed a qualitative methodology, of a bibliographical nature, in which important references on the subject were selected, in addition to analyzes of excerpts from the aforementioned narrative. We conclude this article by inferring that Evaristo’s work represents the voice of minorities who find themselves on the margins of society and, on a daily basis, struggle not only to gain space and recognition, since they are also part of the composition of the national identity; but, above all, out of respect and equality

Published: July 2023

La reducida información que se tiene de la situación actual del cultivo cacao a lo largo de valle de los ríos Apurímac, Ene y Mantaro (VRAEM) ha hecho que se tenga limitaciones para su promoción. Por lo tanto, fue necesario identificar variables estratégicas (VE) y recolectar datos de campo con propósito de promover y conocer la situación del cultivo. Para lo primero, se empleó la metodología del análisis estructural MICMAC (Matriz de Impacto Cruzado y Multiplicación Aplicada a una Clasificación) y en segundo aspecto se realizaron encuestas a 223 agricultores. Resultando que la promoción del cultivo en los jóvenes es una variable que aportaría a la mejora de la cadena productiva. No obstante, no se encontró en ningún distrito la existencia de agricultores menores de 41 años. Además, se identificó que las variables agricultura orgánica, caracterización de genotipos locales e implementación de jardines clonales catalizarían el sistema de producción. Sin embargo, la preferencia por los cultivos de las variedades CCN51 y criollos (>50%). Asimismo, la muy baja cantidad de agricultores certificados (2% - 10%). En suma, nos muestran la urgencia de atender estos temas con el propósito de mejorar la cadena productiva de cacao e involucrar organizaciones públicas y privadas.

El sistema judicial latinoamericano se basa en la encarcelación, en Perú la población tiene la percepción de que si el sistema judicial encarcela más personas es de buena calidad, esto se debe a que en muchas ocasiones personas con alto rango o posición económica se han librado de la cárcel en muchas ocasiones, viéndose como impunes. Metodología: Estudio de corte transversal, la población estuvo comprendida por los internos de los 69 penales que existen en Perú registrados en la base de datos del Instituto Nacional Penitenciario del Perú a través de su base de datos públicos. El estudio no necesito la revisión de un comité de ética ya que los datos son públicos. Resultados: a diciembre de 2019 la capacidad de albergue de los penales a nivel nacional es de 40,137, sin embargo, la población penal fue 95,548 (238%), es decir hay 138 % de sobrepoblación. Conclusiones: el hacinamiento en las prisiones en las cárceles del Perú es un problema rampante, este debe ser solucionado aplicando reformas en el sistema judicial, en el hospedaje penitenciario y el control de las enfermedades infecciosas.
On the role of applied potential in adsorption of dibenzyl viologen molecules on HOPG surface

Published: July 2023

Tuning the charge carier concentration of graphene is one of the key challenges in the field of graphene research. An effective solution for this is to dope graphene by organic molecules that physisorb or self-assemble on the graphene surface. Therefore, a comprehensive understanding of their surface structures at the molecular level is realy nessesary. In this contribution, we report on the role of the applied electrode potential in the adsorption/self-assembly of such n-dope molecule, dibenzyl viologen (DBV), on a highly oriented pyrolytic graphte (HOPG) surface (a multi-layer graphene material) determined by using a combination of cyclic voltametry (CV) and electrochemical scanning tunneling microscopy (ECSTM) methods. The obtained results reveal that dibenzyl viologen molecules can exist at three redox states corresponding to three respective adsorbate phases depending on the applied electrode potential. The DBV2+ molecucles physisorb and form disordered phase, whereas DBV·+ and DBV0 moleucles self-assemble forming dimer and stacking phases, respectively, on HOPG surface.

Two ionic liquids triethylammonium oleate and  triethylammonium stearate were synthesized from fatty acids and triethyl amine using two different methods (one step and three step methods). The yield triethylammonium oleate rearch 68.8-74% (one step method) and 86.3% (three step method) and of triethylammonium stearate rearch 68.7-74.1 (one step method) and 83.5% (three step method). The one step method spends more time but less chemicals and brings higher yield. FT-IR and 1H-NMR spectra of ILs obtained from both method was measured. The results showed that synthesis method doesn’t affect on the structure of the products and ILs obtained from one step method has higher purity.

Published: July 2023

Oxygen is essential for human respiration and the existence of all living organisms. Medically it is used to treat diseases related to impaired respiratory function. In industrial scale, gaseous oxygen is separated from the air by liquefaction and fractional distillation techniques, while on a small and medium scale oxygen is usually separated by using zeolite molecular sieves and pressure swing adsorption (PSA) technology. During the Covid-19 pandemic, the demand for oxygen concentrators (PSA type) for personal and family use is very high. However, there isn’t any Vietnamese factory for production oxygen concentrator, so it is imported from abroad. In this paper, a pilot-scale oxygen concentrator was built at the Department of chemical process equipment, Hanoi University of Science and Technology. The operation of the device has been simulated and optimized on Aspen Adsorption software. The optimization parameters obtained will be used to design the equipment in industrial scale.

Removing iodide from aqueous solution using biomaterials synthesized from pomelo fruit peel-derived biochar with low costs is a new approach in environmental science and application. The material was characterized by various analytic methods such as XRD, SEM, BET, and FTIR. Additionally, Leuco crystal violet method was used to ascertain the quantity of iodide (I-) adsorbed and UV-Vis spectroscopy was used to quantify it. The effects of pH (2–11) and interaction duration (3–42 h) on the iodide adsorption were carefully examined. To examine the isotherm and dynamic characteristics of the substance, the Langmuir, Freundlich, pseudo-first-order, pseudo-second-order, and in-diffusion models were applied. The results showed that the maximum adsorption took place at pH 2 for 2520 min and the adsorption followed the intra-diffusion kinetic model as well as the maximum capacity (qm) derived from the Langmuir equation was 7,06 mg/g at 303 K, this number is higher than the maximum uptake capacity based on experiment findings (qe = 1,46 mg/g).

Modifying platinum microelectrodes with electrochemically reduced graphene oxide for application in electrochemical ascorbic acid sensor
Authors: Tran Thi Luyen  , Tran Vinh Hoang
Published: July 2023

Graphene oxide drop-casted on a platinum microelectrode was successfully changed to reduced graphene oxide by using a cyclic voltammetry method. The presence of an electrochemically reduced graphene oxide layer on the platinum electrode was proved by using scanning electron microscopy images, Raman and Fourier-transform infrared spectroscopy spectra. Cyclic voltammetry and linear sweep voltammetry results indicated that the platinum microelectrode modified with electrochemically reduced graphene oxide can be used as an electrochemical sensor for detection of ascorbic acid in aqueous solutions. In a cyclic voltammetry scan and a linear sweep voltammetry curve corresponding to the presence of ascorbic acid, a peak related to the direct oxidation of ascorbic acid appears. The electrochemical sensor based on the electrochemically reduced graphene oxide material works effectively with a detection limit of 0.04 mM, a detection linear range from 0.04 mM to 1.0 mM, a good repeatability, and especially, a rapid detection time thanks to a direct ascorbic acid detection based on the oxidation of ascorbic acid.

Authors: Phan Thi Thuy Trang  , Nguyen Thi Lan
Published: July 2023

The pH solution is one of the critical factors affecting the photo-Fenton degradation of dyes in wastewater. The photoactivity of Prussian blue/g-C3N4 was investigated using the photodegradation of RhB acidic, neutral, and essential medium. The results implicated that more than 98.5% removal of RhB was achieved at pH = 3.62 after irradiation for 60 minutes under visible light. The photocatalytic activity of Prussian blue/g-C3N4 showed the best performance in an acidic medium. This is due to the formation of hydroxyl radicals during the photocatalytic degradation of RhB. Thus, this study has shown the role and potential of the application of photocatalysts in the degradation of toxic organic compounds the wastewater.
