Introduction: Cervical cancer, is well known in the world, and this disease is a malignant disease that attacks the reproductive organs of a woman that can no longer be tolerated and about which all women should be aware. Therefore, female self-efficacy is crucial for women of childbearing age to advance knowledge and particularly maximize the reproductive health of these women.
 
Aim: Search for data and results from this study, the author wants to determine the significance and the possible correlation between the effectiveness of women of childbearing age and their knowledge of the performance of cervical cancer screening using the VIA method, so that cervical cancer will not be affected.
 
Method: In this quantitative study, researchers used a correlational descriptive design where the approach used was cross-sectional. In this study, researchers used a sample of 97 respondents in the consultation area of the Harapan Raya Community Health Center in Riau Pekanbaru Province. Sampling is carried out by researchers with the greatest care, following predetermined inclusion criteria and using targeted sampling techniques. Likewise, data analysis is carried out using the chi-square test method.
 
Results: Demographic data from this study indicate that 53.6% of respondents were young adults. The majority of 43.3% of respondents have a college degree and the highest data, mothers are only housewives, accounting for 82.5% of respondents. Through the process of univariate analysis, it was determined that a majority of respondents, specifically 62.9%, had a significantly low level of self-efficacy. Furthermore, it was found that 55.7% of the respondents had a sufficient level of knowledge. The use of the chi-square test in data analysis revealed a notable association between self-efficacy and knowledge of women of childbearing age regarding cervical cancer screening using the VIA method, which is inexpensive, effective, and immediate results are known. This association was supported by a p-value of 0.002, indicating statistical significance.
Conclusion: Based on the research results, it was found by researchers that there is a remarkable correlation between self-efficacy and the level of knowledge of women of childbearing age regarding cervical cancer screening using the VIA method, which is a good result to recommend.
 
Recommendation: Researchers recommend that this study be used as a method to increase self-efficacy and knowledge of women of childbearing age in cervical cancer screening using the VIA method.

Authors: Badepally Hareesh Reddy , Rumandla Lavanya , Badineni Mounika , Malikanti Ramesh , Vadija Rajender , Mustyala Kiran Kumar , Malkhed Vasavi
Published: May 2024

One of the most serious medical conditions is tuberculosis (TB). In Mycobacterium tuberculosis (Mtb), the NADH-quinone oxidoreductase subunit C (NuoC) protein is a member of the NADH dehydrogenase family and is essential to the electron transport chain, ATP generation, and energy production. One possible pharmacological target for finding inhibitors is the Nuoc protein. Computational approaches are used to identify the 3D structural characteristics of the Nuoc protein, and several validation methods are used to verify the results. Using several ligand databases, virtual screening tests surrounding the active site were carried out to find drug-like molecules. The study found that the amino acid residues that are important in drug-target interactions are ARG98, ARG75 (basic), ASP99, ASP189, ASP98 (acidic), LEU101, LEU194 (nonpolar neutral), THR180 (polar neutral), GLU177 (polar neutral), TYR181 (polar neutral), PRO102, PRO192 (nonpolar neutral), and HIS191 (basic). The findings demonstrate the ligand molecules’ drug-like ability to inhibit NuoC proteins. The structural data may be used to develop novel therapeutic scaffolds for the treatment of tuberculosis (TB), in conjunction with information on the active site and the chosen ligand molecules.

Published: May 2024

Este libro ofrece al lector una cartografía de la literatura publicada en los últimos veinte años por autores mexicanos. Las propuestas estéticas en torno a lo fantástico, los ritos de iniciación, los entornos familiares, la migración, el humor, la paranoia y las experiencias carcelarias son herederas de una tradición literaria particular y rica, como lo es la hispanoamericana, pero también de contextos culturales en crisis permanente que tensa lo local con lo global. La intención es sumarse a los distintos esfuerzos académicos y editoriales que buscan comprender el comportamiento del campo literario actual, su proceso, su constante repetición, para –acaso– hallar aquellas obras que indagan en las problemáticas contemporáneas. Los gustos y los intereses temáticos sugirieron el señalamiento de acuerdos y disensos con apuestas académicas semejantes. La rueda sigue su movimiento y los engranajes no son perfectos, pero el camino sí que es transitable. En esta ocasión, quienes suscribimos la coordinación del volumen buscamos que jóvenes investigadoras e investigadores aportaran su visión analítica, crítica e interpretativa sobre las narrativas del siglo XXI.

Published: May 2024

The availability of embankment material and the quality of the material is one of the problems in planning a dam, especially impermeable material which must be watertight. With the GeoStudio application, the dam will be modeled to observe the stability of the dam, especially against landslides and seepage. Modeling I is modeled with core zone material using upstream borrow clay material and modeling II using downstream borrow clay material. Modeling III and IV used the same core material with the addition geomembrane material between the transition zone and the upstream filter. The geomembrane was added to observe and compare the effect of use on the stability. The weir body was analyzed under conditions when the weir body was completed, flood water level, normal water level, low water level and rapid drawndown water condition. Modeling III with upstream borrow clay material and geomembrane between the transition zone and upstream filter is the design with the best stability with the most critical avalanche safety factor of 2.459 downstream of the weir under flood water level conditions. The seepage discharge downstream of the weir is 0.0017 m³/dt/m and the maximum seepage discharge is 0.0026 m³/dt/m under flood water level conditions.

Criminal threats in Latvia raised by Russian aggression in Ukraine
Authors:   Rīga Stradiņš University, Latvia, Baumanis Jānis
Published: May 2024

On 24 February 2022, Russia’s aggression against Ukraine escalated into a broader armed invasion of the Ukrainian territory and a subsequent protracted war. This event significantly impacted various social, political, legal and other processes worldwide. This global upheaval not only influenced international processes but also had an impact on various national-level processes, including the introduction of changes within the spectrum of criminal threats. Upon realising the extent of interests being criminally violated, the author of the research chose to narrow the research focus exclusively to the Latvian level. Moreover, the range of interests violated at the Latvian level can be quite extensive, as the commission of any criminal offence outlined in the Criminal Law can be indirectly linked to the war in Ukraine. With this in mind, the study aims to identify the criminal threats in Latvia stemming from Russia’s aggression in Ukraine by analysing statistical indicators of registered criminal offences, the activities of lawmakers in the development of criminal law norms and case law in situations where Ukraine is mentioned in the description of the alleged criminal offence. Keywords: criminal threat; violation of sanctions; hate crime; crimes against the state.
In proof in criminal cases on sexual abuse against child
Authors:   Rezekne Academy of Technologies, Latvia, Bulgakova Ilona , Božko-Čače Margarita ,   Rezekne Academy of Technologies, Latvia
Published: May 2024

The objectives of this research work are to reflect on the circumstances of the fact in proof in criminal cases regarding sexual violence against a child and to identify the problems of proof. The research has revealed the problems concerned with the identification, investigation, and evaluation of the circumstances to be proved. The main results of the research: the main matter of the fact in proof of sexual violence is related to the clear identification of the object of threat, the actus reus of sexual abuse. To achieve this, from the very beginning of investigation, in the pre-trial procedure, the investigating officer should be carefully prepared, including the place and time of interrogation and the choice of questions. Also, the interrogation of the injured child should be conducted according to the provisions of the Criminal Law. When investigating a case of sexual violence against child, from the very beginning of the investigation, the task of the investigating officer is to clarify and investigate the criminalistics versions in order to identify the principal fact, including the criminal act’s actual circumstances. Keywords: a specially protected injured person; child; criminal procedure; fact in proof; sexual abuse.
The consolidation of putin’s power through legal and political means: implications for identity construction
Authors:   Rīga Stradiņš University, Latvia, Vrobļevska Elīna , Rātfelders Toms ,   University of Delaware, USA
Published: May 2024

The sources of identity for the state are subjected to a constant process of change dependent upon, but not reduced to the aspect of who is creating the collective consciousness of the state’s self-awareness at the specific point in time. This paper traces and analyses the legal and political changes made in Russia’s legislature and governance model over the course of the past 20 years. This article argues that constitutional and legal changes have promoted and identify the president of Russia as a ‘curator’ of foreign policy—controlling the decisions made and the state identity that supplements them or enables them. As a result, it can be argued that although in the Russian political elite, several key agents can be identified as the ones shaping and influencing Russia’s foreign policy and constructing its identity, President Vladimir Putin, from a legal and political perspective has the most legal power and authority and thus can be considered the main agent of Russia’s identity construction. Keywords: consolidation; constitution; identity; power; Putin; Russia.
Space Mining
Authors: Thibault Isabelle M.
Published: May 2024

The Outer Space Treaty, the leading source of law for activities in space, has laid out various limitations and regulations regarding actions in space and how space can be used. One of these limitations is commonly referred to as the “non-appropriation principle.” The non-appropriation principle prohibits nations from making claims of sovereignty over celestial bodies in space. This presents a problem as the space industry continues to progress because it causes uncertainty regarding the meaning of appropriation, what is classified as a celestial body, what acts are allowed, and who specifically is prohibited from acting. This Comment identifies these problems and their potential solutions, specifically with the proposition of space mining in mind.
The Post-Racial Deception of the Roberts Court
Authors: Powell Cedric M.
Published: May 2024

Students for Fair Admissions v. Harvard/UNC (SFFA) is a post-racial deception unmoored from precedent and societal reality. SFFA deceives the polity and signals an all out assault on anti-discrimination law. To preserve its institutional legitimacy, the Roberts Court promotes doctrinal and conceptual distortions—post-racial deceptions of cognizable injuries advanced through reverse discrimination claims of white plaintiffs; racial proxy claims of discrimination proffered by Asian-Americans; and the fairness rationale of the Court’s circular post-racial edict that “the way to stop discrimination on the basis of race is to stop discriminating on the basis of race.” Chief Justice Roberts’s majority opinion discards the anti-subordination principle of the Fourteenth Amendment and replaces it with a post-racial anti-differentiation principle: “Eliminating racial discrimination means eliminating all of it.” Expanding the circularity of Chief Justice Roberts’s post-racialism even further, Justice Thomas’s concurrence offers an ostensibly originalist reinterpretation of the Fourteenth Amendment that erases the race-conscious history of the Reconstruction Amendments and reframes it as the codification of the Declaration of Independence. Rejecting this post-racial deception, Justices Sotomayor and Jackson, in dissent, foreground the anti-subordination principle as the essential doctrinal core of the Fourteenth Amendment and offer a rebuke of the Court’s facile post-racialism with a comprehensive discussion of systemic racism, structural inequality, and the present-day effects of past discrimination. The Court’s post-racial constitutionalism is a post-racial deception which must be discredited and rejected if we are to ever achieve the multi-racial democracy promised by the Second Founding.
Operando Spectroscopy of Catalysts Exploiting Multi-technique and Modulated Excitation Approaches
Authors: Buttignol Filippo , Maggiulli Luca , Kochetygov Ilia , Alxneit Ivo , Ferri Davide
Published: May 2024

Operando spectroscopy combines the in situ determination of material structure by spectroscopy/diffraction techniques with the measurement of material performance, which is conversion/selectivity in the field of heterogeneous catalysis. A central question in operando spectroscopy is whether the signatures visible by the characterization methods are responsible for catalyst performance. Individual analytical methods can provide useful information, but their combination (multi-technique approach) is essential to obtain a complete perspective on molecular reaction mechanisms. This approach must be coupled to experimental protocols and mathematical algorithms enabling the ability to disentangle the contribution of the active structure from the unresponsive one. Here, we report an account with examples from our own research activities in catalysis science.
Design and Application of a Gas Diffusion Electrode (GDE) Cell for Operando and In Situ Studies
Authors: Wiberg Gustav K. H. , Pittkowski Rebecca K. , Punke Stefanie , Aalling-Frederiksen Olivia , Jensen Kirsten M. Ø. , Arenz Matthias
Published: May 2024

Presented here is an electrochemical three-electrode Gas Diffusion Electrode (GDE) cell tailored for operandoand in situ investigations of electrocatalytic processes, with a particular focus on X-ray scattering studies. The optimized cell is engineered to accommodate the minimal sample-detector distances requisite for comprehensive X-ray total scattering investigations. An in-depth understanding of catalytic processes requires their study under ‘working’ conditions. Configured as a flow-cell, the setup therefore enables the examination of electrocatalysts under high current densities and associated gas evolution phenomena, particularly pertinent for reactions like the oxygen evolution reaction (OER). Notably, its transparency simplifies cell alignment, troubleshooting, and facilitates scans through the catalyst layer, crucial for background corrections. Demonstrating its versatility, we showcase its utility through Small Angle X-ray Scattering (SAXS), X-ray Diffraction (XRD), and X-ray Pair Distribution Function (PDF) analyses of total scattering data.
RITUAL ENCLOSURES OF THE KENT SETTLEMENT
Authors: Ломан В.Г.
Published: May 2024

В конце эпохи бронзы на территории Казахстана и российского Алтая распространилась саргаринско-алексеевская культура (САК), входившая в общность культур валиковой керамики. Крупнейшим поселением САК является Кент (Карагандинская область, Казахстан). На восточной окраине памятника располагаются 3 большие каменные ограды, значительно превышающие своими размерами жилищные постройки. Статья посвящена публикации материалов одной из оград. Рассматриваются конструктивные особенности, дается описание материала. На основании определенных признаков и ряда аналогий делается вывод о ритуальном назначении больших оград поселения Кент.

At the final stage of the Bronze Age the Sargary-Alekseevskaya culture (SAC) that formed part of the Roller Ceramics cultural entity spread across Kazakhstan and the Russian part of the Altai. Kent (Karaganda region, Kazakhstan) is the largest SAC settlement. Three stone enclosures that are much larger and higher than the dwellings are located on the eastern fringe of the site. The paper is devoted to the publication of the materials from one of the enclosures. The constructive features are considered and a description of the material is presented. Proceeding from the analysis of certain features and a number of analogies the conclusion is made that the large enclosures at Kent functioned as ritual structures.
THE MEDIEVAL CEMETERY OF GNEZDILOVO: FINDS FROM THE TOPSOIL AND SPATIAL ORGANIZATION OF THE CEMETERY
Authors: Макаров Н.А. , Красникова А.М. , Шевченко В.А.
Published: May 2024

В статье предпринята попытка использования средневековых предметов из пахотного слоя, собранных при обследовании одного из могильников в Суздальском Ополье, как материала для определения территории некрополя, реконструкции его пространственной структуры, выделения его древнейшего ядра и характеристики погребального обряда. Пахотный слой со средневековыми находками из разрушенных погребений рассматривается как отдельный компонент подобных памятников, трансформированный продолжительной сельскохозяйственной деятельностью, но не утративший информационный потенциал. Общая картина пространственного развития могильника Гнездилово и многообразия практиковавшихся здесь погребальных обрядов воссоздается с привлечением материалов геофизических исследований и выборочных раскопок на отдельных участках.

The paper has attempted to use medieval items from the topsoil collected during the survey of one of the cemeteries in Suzdal Opolye as material for determining the area occupied by the cemetery, reconstructing its spatial structure and identifying its oldest core as well as characteristics of the funerary rite. The topsoil containing medieval finds from disturbed graves is considered to be a separate component of such sites which, though transformed by continued agricultural activity, has not lost its informational potential. The overall picture of the Gnezdilovo cemetery spatial development and diversity of funerary rites practiced has been recreated using materials of geophysical studies and excavations in some sections.

Published: May 2024

Несмотря на длительную историю изучения памятников наскального искусства Минусинской котловины, некоторые до сих пор остаются до конца неизученными. Одним из таких памятников является Тепсей, изображения которого в последние годы обследуют и документируют специалисты кафедры археологии КемГУ. В 2021-2022 гг. в весенне-летний период, когда уровень воды в Красноярском водохранилище из-за сброса воды был как никогда низким, авторам удалось провести обследования прибрежных скал Тепсея у реки Тубы (Усть-Туба) (рис. 1). В результате разведок удалось выявить несколько участков с ранее неизвестными наскальными изображениями: фигуры быков раннего пласта, гравированное изображение животного в скифском стиле, гравированные рисунки коней, рунические знаки, тамги и пр. Наибольшее количество найденных рисунков относится к т. н. народному искусству и датируется Новым временем (XVII - нач. XX в.) - это изображения коней, всадников, верблюдов, оленей, собак, парохода и пр. Открытия «позднего» пласта изображений позволяют расширить имеющиеся представления о некоторых сторонах жизни обитателей этих территорий и их соседей, окружавший их животный мир, мифологические и эпические представления, занимавшие умы древних художников, а также отдельные страницы истории края.

While the studies of rock art sites in the Minusinsk Depression have a long history, some of such sites have not yet been fully examined. Tepsei is one of these sites; it is one of the largest in the Middle Yenisei region. In recent years the specialists of the Archaeology Department at Kemerovo State University have been examining and documenting its rock art images. In 2021-2022 during the spring-summer period, when the level in the Krasnoyarsk storage reservoir was record low because of water discharge, the authors succeeded in conducting a survey of the Tepsei rocks on the Tuba river banks (Fig. 1). The reconnaissance identified several areas with earlier unknown rock images, namely, figures of the bulls from the earlier layer; an engraved figure of an animal made in a Scythian style; engraved drawings of horses; runic signs and symbols, and tamgas, etc. Most found drawings refer to the so called ‘folk’ art dating to the Modern Period (17th - early 20th centuries). This group of drawings includes images of horses, horse riders, camels, deer, dogs, a steamboat, etc. The discoveries of the ‘later’ layer of images have greatly added to our understanding of some aspects of life of people who inhabited these areas as well as their neighbors, the animal world, mythological and epical ideas of ancient artists as well as understanding of specific chapters of history related to this region.

Dissociation of Gas Hydrates in the Combustion Environment
Authors: Donskoy Igor
Published: May 2024

This paper proposes mathematical models of gas hydrate decomposition in high-temperature media. These models are based on heat and mass balances with a set of assumptions about transfer mechanisms and features of chemical reactions. The calculations provide an insight into dynamics of hydrate particles in a flame environment and shed light on possible results of interaction between the combustion front and emission of gas and vapor. Several examples are provided to illustrate the potential of hydrates as a fuel and as a flame extinguishing material. The developed models enable the generation of numerical estimates, which can be employed to design technologies for beneficial uses of gas hydrates.

We report the infrared photodissociation spectrum of tagged protonated valine in the range 1000 – 1900 cm-1, prepared in a cryogenic ion trap. Comparison of experimental results with calculated infrared spectra based on density functional theory shows that the hydroxyl group of the carboxylic acid functionality and the protonated amine group adopt a trans configuration. Nitrogen and methane molecules were used as messenger tags, with optimal tagging temperatures of 30 K for N2 and 60 K for CH4. While the calculated infrared spectra of the tagged ion suggest only a weak influence of the messenger tag on the frequency positions of ValH+, the measured intensities for N2-tagged ValH+ are strongly suppressed for all but the highest frequency features at 1773 cm-1. We trace this behavior to the binding energy of the N2 tag, which is significantly higher than that of CH4, based on CCSD(T) calculations and rate estimates for photoinduced unimolecular dissociation from statistical theory.
Surface Melting Promoted by Hydrogenation: Guidelines for Superhydride Synthesis

The synthesis of new superhydrides with high superconducting Tc is challenging owing to the high temperatures and pressures required. Herein, we use machine-learning potential molecular dynamics simulations to investigate the initial stages of superhydride formation in calcium hydrides. Upon contact with high-pressure H2, the surface of CaH2 melts, leading to CaH4 formation. This surface melting, facilitated by the negative enthalpy of the hydrogenation reaction, proceeds via a liquid CaH4 intermediate state. Our findings show that surface melting becomes more favorable than the melting of the superhydride bulk under high pressure, reducing the activation energy required for hydrogenation. From these thermodynamics, we propose superhydride synthesis guidelines based on bulk properties: superhydride melting temperature and pressure-dependent hydrogenation enthalpy, readily determined through supplementary calculations during structure prediction workflows.
Counterion loss from charged surface-bound complexes drives the formation of loosely packed monolayers

The functionality of multicomponent self-assembled monolayers (SAMs) can be severely diminished by the segregation of like components into nanoscale domains, a process that maximizes favorable short-range intermolecular interactions. Here, we explore the use of a modular family of sulfur-functionalized metal bis(terpyridine) complexes ([M(tpy-R)2]2+(PF6–)2) to prepare mixed SAMs, considering that the comparable structure, dimensions, and ionic composition of these species should render them interchangeable within the adsorbed surface layer. While surface voltammetry experiments show these SAMs do exhibit compositions representative of their assembly solutions, they also suggest, in line with previous reports, that adjacent complexes in the monolayer are separated by a gap of ~1 nm. Remarkably, X-ray photoelectron spectroscopy studies reveal no F 1s peak features that would confirm the proliferation of PF6− counterions on the surface. We propose that the loose packed structure of these SAMs results from the loss or exchange of PF6– counterions which introduces significant repulsive Coulomb interactions between the adsorbed 2+ charged complexes. The hypothesis is supported by an electrostatic model which indicates these complexes should form close packed SAMs if mobile counterions are present. First-principles calculations demonstrate that complex-counterion binding interactions are weakened by charge transfer to the gold substrate, suggesting this may play an important role in the formation of such low coverage SAMs. Together, this study raises important questions regarding the assembly, organization, and composition of charged SAMs, and highlights new opportunities in the design of multicomponent monolayer assemblies with free volume, for example, to facilitate surface-based reactions or support molecular switches.
Computation-Guided Exploration of The Reaction Parameter Space of N,N-Dimethylformamide Hydrolysis

Navigating the reaction parameter space can pose challenges, especially considering the exponential growth in the number of parameters even in seemingly straightforward chemical reactions. Consequently, recent research efforts have been increasingly dedicated to the development of computational tools aimed at facilitating the exploration process. Herein, we introduce ChemSPX, a Python-based program specifically crafted for exploring the complex landscape of reaction parameter space. We propose the use of the inverse distance function to map reaction parameter space and efficiently sample sparse regions. This is implemented in ChemSPX to allow the user to simply generate sets of reaction conditions that efficiently sample wide parameter spaces. In addition, the program includes tools necessary for the analysis and comprehension of the multidimensional parameter space landscape. The developed algorithms were utilized to experimentally investigate the hydrolysis of N,N- dimethylformamide (DMF), a commonly employed solvent, in the specific context of metal- organic framework synthesis. We use ChemSPX to generate batches of experiments to sample parameter space, starting from an empty space, but subsequently assessing undersampled regions. We use statistical analysis and machine learning models to show that addition of strong acids induces hydrolysis, generating up to 1.0% (w/w) formic acid. The results show that ChemSPX can generate datasets that efficiently sample parameter space, in this case allowing the user to distinguish the individual effects of five different physical and chemical variables on reaction outcome.
A simple evaluation of adiabatic proton tunneling across the electrified double layer

Published: May 2024

Coupled proton-electron transfer (CPET) reactions are likely to play a pivotal role in the global transition to a sustainable energy future. Our atomic scale understanding of this class of reactions has been significantly improved by developments in density functional theory (DFT) simulations. The ultimate goal of such simulations is to intelligently predict rates of CPET reactions at the electrified double layer, leading to the design of new catalysts. These studies often utilize harmonic transition state theory (HTST), which assumes that quantum tunneling through energy barriers is negligible. In this study, we present a simple evaluation of the contribution of quantum tunneling in the adiabatic limit of CPET reactions. We investigate the effect of different potential profiles on tunneling probabilities and compare these profiles with calculated CPET minimum energy paths (MEPs). We find that the calculated CPET MEPs can be significantly stiffer than the commonly used Eckart profile, and study the effect of changing barrier height and width on overall zero curvature tunneling correction factors. Depending on the reaction of interest and the bulk pH, proton tunneling can be a non-negligible phenomenon for CPET reactions at the electrified double layer. In particular, reactions involving large barriers are predicted to have significant contributions from non-classical tunneling, possibly explaining observed kinetic isotope effects for the hydrogen evolution reaction (HER) in alkaline media. Our model choices are significantly simplified -- for example, neglecting the effects of reaction coordinate curvature and vibronic coupling -- suggesting that our predicted tunneling contributions may be underestimated. However, our findings provide a simple way to evaluate whether tunneling is relevant for a particular CPET reaction of interest.
