Los niños y niñas que han sido víctimas de violencia intrafamiliar en el Ecuador recaen en una constante revictimización al no contar con las garantías adecuadas para proteger los derechos de: interés superior, vida digna, seguridad, bienestar e integridad personal. Se ha podido evidenciar que frente a situaciones de flagrancia se genera una doble vulnerabilidad provocando desconfianza en el sistema administrativo y judicial debido a la falta de celeridad y trato oportuno. En el contexto descrito la investigación está orientada a presentar un análisis jurídico respecto de las medidas de protección y su debida aplicación tendientes a precautelar los derechos de niños y niñas de forma inmediata, evitando una mayor inseguridad. Este trabajo encuadra en una investigación cualitativa de carácter descriptivo qué cuenta con soporte bibliográfico y documental para dar cumplimiento al objetivo planteado. Como resultado se evidencian vacíos estructurales en las leyes vigentes lo que llevan a determinar la necesidad de subsanar este problema para garantizar de una mejor manera la protección de los derechos de niños y niñas y una mayor confianza en el sistema ecuatoriano de protección de derechos.

Based on the core data from the Koblandy-3 well from the Upper Devonian strata of the presalt complex, the results of RockEval and isotopic analysis are presented. Intervals of kerogen-siliceous-carbonate rocks enriched in organic matter have been established, which, according to a complex of microand macrocharacteristics, can be attributed to domanikoid-type sediments. The Domanikoid highcarbon formation of the neighboring Volga-Ural Basin is an effective source rock. The generative potential of the established domanikoid-type sediments of the Koblandy-3 well is characterized by high TOC values of 0.1-5.7%, the Production Index (PI) varies from 0.1-0.3, which corresponds to the oil window. Three lithotypes of domanikoid-type sediments deposited in predominantly deep marine environment have been established. The association of potential reef bodies in the vicinity of domanikoid-type source rocks indicate in favor of petroleum system within the upper Devonian presalt complex of the Koblandy-Tamdy uplift zone

The solution to the problems of the construction of deep wells is possible when creating downhole tools on a fundamentally new ideological basis, involving physical principles, technical solutions unconventional in the field of drilling equipment. It is important to take into account the energy resources that increase with depth. Following this concept, based on the tasks of geological exploration, a downhole layout has been developed and introduced into the production of drilling wells, with design features and technological capabilities focused on a comprehensive solution to the problems of well wiring. Structurally, the downhole layout aimed at maximizing the potential energy of the working fluid is universal, designed for drilling wells with core sampling of increased diameter (100 mm or more), and with a solid face. In addition to the outer pipe and core receiver, the downhole layout is equipped with diamond drill heads with a stepped matrix, with a separate system of flushing channels, collectively realizing the effect of hydro-mechanical destruction of rocks. By introducing into the composition of the bottom-hole layout, converting the ascending flow into a rotational-ascending one, the problem of removing sludge from under the end of the stepped matrix is effectively solved. Production tests of the downhole layout with core sampling were carried out at the polymetals deposit of Central Kazakhstan, solid face during drilling of groundwater wells in the territory of the Almaty region. According to the results of production tests, it was found that the hydro-mechanical destruction of rocks is especially effective in combination with diamond drill heads with a stepped matrix. The presence of a turbulator-expander in the bottom-hole layout made it possible to significantly increase the amount of incoming sludge of drilled rock in the well sump, especially when drilling wells with a solid face. In comparable geological and technical conditions of drilling wells, serial core sets HQ with a drilling diameter of 95.6 mm had the following indicators: energy consumption – 2.1-2.4 kW / hour, core yield with a diameter of 63 mm – 93%, specific lumpiness of the core – 5-8 pcs / per linear meter of drilling, drilling was carried out at an axial load of 2200-2500 kgf, rotation speed 500-700 rpm. Similar indicators of the downhole layout: energy consumption – 1.2-1.5 kW / hour, core yield – 98-100% with a diameter of 112 mm, specific lumpiness – 2-3 pieces, axial load – 700-900 kgf, rotation speed – 300-400 rpm.

Deterioration of the qualitative and quantitative characteristics of the hydrocarbon resource base leads to an increase in the share of hard-to-recover reserves. In an environment where the share of hard-to-recover oil reserves in the oil industry is steadily increasing, the need to create effective methods to increase oil recovery is acute. The method of flooding at the present stage of the development of the oil industry is considered the most progressive, meeting the basic principles of oil field development. However, during flooding, a large proportion of oil reserves remains in the reservoir, and therefore, technologies are currently being sought and developed in all major oil companies that will increase the oil recovery coefficient. Currently, there is a growing interest in the application of the technology of water-gas exposure to oil formations to increase oil production. This is due to the fact that the water-gas effects combine the positive aspects of well-known oil production technologies, such as flooding and the method of pumping hydrocarbon gas into the reservoir. Experimental and theoretical studies have established that one of the most effective methods of oil recovery can be methods based on injection of hydrocarbon gases and water-gas mixtures into the reservoir. Experiments were conducted to study the mechanism of displacement and determine the coefficient of displacement of oil by gases and water in various combinations in relation to some fields. The experiments were carried out under conditions as close as possible to reservoir conditions: recombined or reservoir oil samples, core from productive deposits were used. The pressure and temperatures corresponded to their reservoir values. As the results of experiments, the increase in the oil displacement coefficient depends on the type of gas injected (hydrocarbon equilibrium and nonequilibrium with reservoir oil, acidic, inert, etc.) and modification of the injection technology of agents (sequential, alternate, joint). To study the expected results of testing the technology of water-gas exposure at the Kalamkas field, the experience of using this method at other fields is considered. The paper presents an analysis of the experience of implementing the technology of water-gas exposure at various locations. A review analysis of the results of the technology implementation was carried out to determine the advantages and possibilities of using the technology of watergas exposure in the conditions of the Mangystau field.

Currently, a large number of fields with high-viscosity oil are being developed. Increasing the degree of oil recovery from the subsoil of developed fields using effective methods of active influence is an important scientific and technical task for employees of oil producing enterprises. One of the most effective and promising methods for stabilizing oil production is physical and chemical technologies based on the injection of polymer compositions. Therefore, the authors of the article pursue the goal - to investigate the effectiveness of the use of polymer compositions for further recommendation for use in fields with high-viscosity oils and formations containing hard-to-recover reserves. The article provides an analysis of the results of the study of polymers, namely GL-50 and R-1 on rock samples of various well depths. In this regard, an experiment was carried out to displace oil with various displacing reagents. During the oil displacement experiment with various displacement reagents, the water saturation of the sample and the displacement efficiency were determined. Particular attention is paid to the rate of advancement of the flow of polymers and the propagation of molecules through pores of different diameters. The main goal of this experiment was to determine a more effective polymer for enhanced oil recovery. Comparison of oil displacement efficiency at the stages of polymer injection is given. In the course of the study, the results of determining the displacement coefficients of GL-50 and R-1 polymers were obtained. From the results obtained, it can be assumed that polymer grades have a significant impact on the degree of efficiency of the oil displacement process.

The authors of the publication synthesized bifunctional catalysts based on mesoporous aluminosilicates (MAS) with different binder contents (80 and 65%, respectively) in two ways: the first method consisted in mixing the synthesized aluminosilicate with preliminarily activated bentonite, which was then promoted. Whereas, according to the second method, the synthesized mesoporous aluminosilicate was first promoted, only then mixed with bentonite. The synthesis of bifunctional bimetallic catalysts was carried out using the wet impregnation technique. Acid and physicochemical characteristics were studied using the DRIFT method, TPD-NH3 and the standard nitrogen adsorption/desorption method. It was found that the samples of catalysts with the ratio MAS:H-bentonite = 35:65, prepared according to the first method, have optimal acid characteristics and physicochemical properties.

В работе изучаются аспекты устойчивости нелинейно-упругих тел по отношению к наложенным конечным деформациям. Вопрос изучения основного процесса деформирования исходной среды сведен к решению нелинейной краевой задачи с переменными коэффициентами для конечных возмущений. Решения для возмущений перемещений выбираются в виде рядов содержащих собственные функции. С помощью принципа возможных перемещений вопрос об устойчивости основного состояния сводится к исследованию устойчивости нулевого решения системы обыкновенных дифференциальных уравнений с постоянными коэффициентами. Для данной системы построена функция, которая, при некоторых ограничениях на начальные возмущения будет функцией Ляпунова, которая используется для нахождения областей устойчивости.

The paper studies aspects of the stability of nonlinear elastic bodies with respect to superimposed finite deformations. The question of studying the basic process of deformation of the initial medium is reduced to solving a nonlinear boundary value problem with variable coefficients for finite perturbations. Solutions for displacement perturbations are selected in the form of series containing eigenfunctions. Using the principle of possible displacements, the question of the stability of the ground state is reduced to the study of the stability of the zero solution of a system of ordinary differential equations with constant coefficients. For this system, a function is constructed, which, with some restrictions on the initial perturbations, will be the Lyapunov function, which is used to find stability regions.

The general form of the tensor relation on the growing surface is shown, taking into account the additional selected direction. The necessary system of independent arguments of the constitutive tensor function on the growing surface in the considered case is determined. A complete set of joint rational invariants of the stress tensor and characteristic directors is determined.

Soil provides crucial nutrients and water for the growth of canola, which is one of the most essential economic crops for prairie province in Canada. Therefore, effective and efficient methods are required to modify soil properties to improve crop development. This study systematically analyzed the combined effects of tillage operation and crop residue management on soil features. Thus, the relationship between soil properties and crop yield was also evaluated. More specifically, Aftermarket chopper treatment could cause rela tively higher soil moisture and temperature, while the Original Equipment Manufacturer (OEM) treatment could also result in dramatically higher soil organic matter (SOM) loss than Aftermarket treatment. The significantly more soil water and slightly higher soil temperature created by Aftermarket treatment was beneficial for crop yield. Although OEM treatment could cause more SOM loss, the final crop yield through this method was still lower than that using Aftermarket treatment, implying that the influence of SOM loss on crop growth remained contestable. Meanwhile, Fourier-transform infrared (FTIR) spectra showed the peaks of amides and carboxylic acids was declined during the growth of canola, which indicated that these organic contents played an essential role in the crop development. Finally, the Aftermarket * Harrow treatment was more suitable for canola cultivation, with largest amount of crop harvest and short loss of soil organic contents in the meantime.

The study of heavy metal interactions with soils under specific climatic circumstances might lead to a better understanding of heavy metal migration and provide further information for local pollution control. In this work, we collected soil samples from the world's largest light rare earth mining district, Bayan Obo mine district, and assessed the heavy metal content in the soil at various depths. The extraction effectiveness of Diethylenetriaminepentaacetic acid (DTPA) and Toxicity Characteristic Leaching Procedure (TCLP) for heavy metals in surface soil were compared. Furthermore, we studied the longitudinal transport of heavy metals under precipitation conditions using simulated experiments and kinetic fitting. We discovered that pH has a significant impact on heavy metal release. Precipitation easily transports Zn, Pb, and Cr to deeper layers of the soil. The modified Elvoich equation could better describe heavy metal release patterns.

The study of plants as a biofilter is highly relevant in the field of air pollution science to ecological restoration in urban, which is connected to the ecosystem and human health. The aim of this present study was designed to evaluate the use of Riccia as a biofilter for particulate matter. The treatment box was designed using the Computational Fluid Dynamic (CFD) model. The alignment of the biofilter plant was designed and performed in three different arrangements blocking, zigzag, and parallel panels. The particulate matter was generated by simulated B7 diesel fuel combustion smoke using a smoke generator and loaded into the chamber with air velocities of 0.5, 1.0, 1.5, and 2.0 m/s via a Laser dust sensor for both inlet and outlet air. The adsorption efficiency of the PM adsorbed on the biofilter plant was calculated. The physical properties, physiological, and biochemical parameters of the study plant such as Air pollution tolerance index (APTI), Dust capturing potential were investigated. Moreover, the micromorphological details of the plant, the volatile organic compounds (VOCs), polyaromatic hydrocarbons (PAHs), and adsorbed metal were analyzed. The study revealed adsorption efficiency was in the range of 2.3%–49.6 %. The highest efficiency values for PM1, PM2.5, and PM10 were 31.4, 40.1, and 49.6, respectively, which belonged to the horizontal panel with a velocity of 2.0 m/s. The alignment of the panel and air velocities affects the efficiency. HS-GC-MS revealed that Riccia can be adsorbed the particulate matter and the quantity of Cd, Pb, and Na were 0.0044 ± 0.0069 mg/gDW, 0.0208 ± 0.0278 mg/gDW, and 0.9395 ± 0.1009 mg/gDW, respectively. The morphological study exhibited a rough surface to enhance the efficiency of the trapped particle matter. The results showed that Riccia was suitable for adsorbing the particulate matter with a diameter of 1–4 μm.
Identifying In-Service Teachers' Perceptions of Developing 21st Century Skills Through Science Education Using TPACK-21 Framework
Authors: Ali Salma , Hernandez James
Published: January 2023

In this digital age, science teachers are continuously confronted with new emerging opportunities and challenges as a result of the rapid rate of discoveries in science and technology and information technology as well. Science educators, therefore, emphasize restructuring the education system to prepare 21st century learners to face complex challenges and prepare them to avail the opportunities at their fullest. This present study aimed to identify in-service science teachers' perceptions of developing 21st century skills through science education by employing an updated TPACK-21 framework. A mixed-methods study, using a survey-based questionnaire and focus group interviews with selected teachers, was undertaken to collect teachers' perspectives. The study revealed that when technology is used by teachers, it is often paired with specific content and pedagogically very different from what teachers are used to performing. The results highlight the need to use technology for innovation and to renovate contemporary teaching practices for 21st century learning.

Discovering a porphyry deposit using tourmaline: a case study from Yukon
Authors: Beckett-Brown C E , McDonald A M , McClenaghan M B
Published: January 2023

As the exploration for porphyry Cu-Au-Mo deposits has become increasingly challenging, the development of more effective techniques directed at detecting buried deposits has become critical. One methodology is to focus on key minerals, one of which is tourmaline,
a robust, ubiquitous mineral in most mineralized porphyry systems. Overall, a combination of physical and chemical characteristics including 1) macro-color, 2) morphology, 3) inclusion populations, and 4) trace-element compositions are useful in discriminating between porphyry- versus
non-porphyry-derived (or related) tourmaline in surficial sediments (Beckett-Brown 2022). These features are applied to tourmaline obtained from stream sediment samples (n = 22) from 16 streams derived from the unglaciated terrain proximal to the Casino calc-alkaline porphyry Cu-Au-Mo deposit (Yukon
Territory, Canada). The obtained tourmaline occurs as two distinct morphologies: 1) individual blocky to prismatic sub- to euhedral grains (Type 1), 2) aggregates of radiating prismatic to acicular sub- to euhedral grains (Type 2). Type 1 grains display trace-element contents that reflect mixed
origins including a mineralized porphyry origin as well metamorphic and pegmatitic (background) environments. Type 2 grains almost exclusively exhibit porphyry-derived trace-element chemistries (i.e., high Sr/Pb ~150 avg. and relatively low Zn/Cu ~2.5 avg. values). In Canadian Creek, that
directly drains from the Casino deposit, samples closest to the deposit contain >70% porphyry-derived tourmaline, while other streams in the region from unprospective drainage basins contain no porphyry-derived tourmaline. At the most distal sample site in Canadian Creek, ~20 km
downstream from Casino, nearly 30% of the recovered tourmaline in the stream sediments is porphyry-related. This method has potential to be a strong indicator of prospectivity and applicable for exploration for porphyry Cu-Au-Mo systems in both unglaciated and glaciated
terrains.
Social Injustice and the Mourning of the Earth: Ecological Reading of Prophetic Texts
Authors: Gatti Nicoletta
Published: January 2023

In the encyclical letter Laudato Sì, Pope Francis proposed an integral ecology, able to listen to the cry of the poor and the cry of the earth. This intuition is present in the ancient prophetic books of Israel where “the earth mourns” (Isa. 24:4) for the social injustice, for human inability to build a fraternal relationship. The article explores how the ecological reading of prophetic texts can become educational tools to guide Christian communities living in the Ghanaian context towards an ‘ecological conversion.’
Rusyfikacja Królestwa Polskiego a ewangelicy i ich akta metrykalne/akta stanu cywilnego: rok 1868. Przyczynek do charakterystyki źródła
Authors: Lesiakowska Renata
Published: January 2023

Artykuł ma charakter przyczynkowy, dotyczy ksiąg metrykalnych Kościoła ewangelicko-augsburskiego w Królestwie Polskim. Analizowane zagadnienie to wprowadzenie przepisu nakazującego spisywanie akt metrykalnych w języku rosyjskim. Prawo to miało obowiązywać od początku 1868 r. (starego stylu), w praktyce jednak w wielu parafiach wprowadzono je w życie z opóźnieniem. W literaturze przedmiotu odnaleźć można jedynie nieliczne wzmianki na ten temat.

Russification of the Kingdom of Poland and Evangelicals and Their Birth, Marriage and Death Records: 1868. A Contribution to the Description of the Source

The article is of contributory nature – it concerns the birth, marriage and death registers of the Evangelical Church of the Augsburg Confession in the Kingdom of Poland. The issue analyzed is the introduction of a regulation demanding that birth, marriage and death registers be written in Russian. This law would enter into force from the beginning of 1868 (Old Style), in practice, however, in many parishes it was brought into effect with delay. Literature on the subject contains only very few mentions on this issue.
Przywilej lokacyjny Izbicy z 1750 r.
Authors: Seroka Henryk
Published: January 2023

Od 1 I 2022 r. Izbica na powrót stała się miastem. O pierwotnym nadaniu Izbicy prawa miejskiego literatura przynosiła różne opinie. Na rozbieżne poglądy i podawanie mylnych informacji o lokacji Izbicy wpływ miało mylenie dokumentów oraz pieczęci miejskich źródeł odnoszących się do Izbicy w woj. lubelskim z Izbicą Kujawską oraz lokowanego w sąsiedztwie wsi Izbica w XVI w. miasta Tarnogóra. Tekst przywileju miejskiej lokacji Izbicy, wydany na prośbę Antoniego Granowskiego, starosty tarnogórskiego, przez Augusta III Sasa w 1750 r., podaje się na podstawie jego oblaty z 1750 r. oraz kopii z 1816 r.

The Foundation Charter of Izbica of 1750

As of January 1, 2022 Izbica became a town again. Literature had presented different opinions about the original granting of the town charter to Izbica. Divergent views and presentations of erroneous information about the foundation of Izbica were the result of confusing documents and town seals in the sources concerning Izbica in the Lublin province with Izbica Kujawska and the Town of Tarnogóra founded in the neighborhood of the village of Izbica in the 16th century. The text of the town foundation charter of Izbica issued by King Augustus III the Saxon at the request of Antoni Granowski, the Tarnogóra starost, in 1750, is quoted on the basis of his record entry of 1750 and the copy of 1816.

Published: January 2023

Introduction: In this period of advancement, forensic dentistry plays crucial role in recognition of a person for ethical and the legal proceedings through the analysis of orofacial and dental characteristics with previous records. In this study, we aimed to assess the interest of dental professionals in participating in forensic dentistry courses and their willingness to introduce this subspecialty in the course curriculum of post graduate studies and to assess the knowledge, attitude and awareness about forensic odontology among dental professionals of Karachi, Pakistan. Methodology: This cross-sectional study was conducted through an online self-administered Knowledge, Attitude, and Practices (KAP) questionnaire with multiple close-end questions. In a convenient sample of 277 participants that includes academic faculty, undergraduates, postgraduates, house officers, dental care professional students (DCP) and dental technician/hygienist from Karachi, Pakistan. Data was measured using IBM SPSS version 26.0. Results: The survey showed that a significant number of study participants have knowledge of forensic dentistry as a branch 70.02% (p value 0.000) of the respondents showed interest to integrate forensic dentistry in the core curriculum. 62% of the Participants showed willingness to opt forensic dentistry as a career or profession. Those who were unwilling had various reasons. A significant number of people maintain dental records (P value = 0.026). Conclusion: There is need for up gradation and recognition of forensic dentistry into the curricula of dentistry to meet the international trends and pursue it as career.
