Authors:   Penza State University, Yashin Andrei V. ,   Branch of the Moscow Witte University
Published: April 2024

The article discusses the issues of ensuring the safety of suspects and accused persons from criminal en-croachments. It is emphasized that, due to their procedural status, these persons have a high predisposition to criminal threats, and are not always able to independently counter them. It is stated that the most common ille-gal act against suspects and accused is coercion to testify. The use of violence against suspects and accused persons held in temporary detention facilities and remand prisons by the staff of those institutions is no less widespread. Violation of the rights and legitimate interests of suspects and accused persons is also allowed by officers of preliminary investigation and inquiry bodies when falsifying evidence and the results of operational and investigative activities. Conclusion dwells upon the fact that ensuring the criminological safety of suspects and accused should become one of the priorities of public authorities. Based on the study, some recommenda-tions are given aimed at increasing the degree of protection of suspects and accused from criminal threats.

Unified Notarial Space within the Eurasian Economic Union: Towards Legislative Harmonization
Authors:   Odintsovo Branch of the Moscow State Institute of International Relations (University) of the Ministry of Foreign Affairs of the Russian Federation,, Tereshchenko Elena I.
Published: April 2024

This article delves into the imperative need for establishing a unified notarial space within the Eurasian Economic Union (EAEU), aimed at propelling member states towards heightened levels of cooperation. Such a framework is envisioned to enhance the efficiency of civil law relations, enable the mobile registration of inheritance rights, facilitate remote and electronic notarial actions, and facilitate the remote exchange of information and documents within the confines of the EAEU. Emphasis is placed on the necessity of forging agreements con- cerning legal assistance, cooperation, and amity among the federal notarial chambers of participating countries. Additionally, a mechanism for formalizing cross-border inheritance rights is proposed, akin to one existing and effi- caciously employed within the European Union. Consideration is given to ensuring confidentiality and information protection through the utilization of electronic systems, allowing for citizen identification and guaranteeing the pre- vention of personal data leakage. In essence, the realization of a unified notarial space within the EAEU heralds a paradigm shift towards enhanced legal interoperability and efficiency, fostering a climate conducive to robust trans- national legal cooperation and harmonization. As such, it represents a significant stride towards the realization of a more integrated and cohesive legal landscape within the Eurasian region.

Published: April 2024

The article analyzes the problem of forming the image of future family among students of pedagogical univer-sities and colleges. As an empirical basis, the results of the author’s sociological research (an online survey of students of pedagogical universities and colleges aged 14 to 35 years, n = 1 800), conducted to clarify the atti-tudes of future teachers regarding family values, were used. The survey data shows that the majority of student youth envision their future families with a preference for having two children. Moreover, the article also de-scribes the perception among student youth of the role of parents in the upbringing of the younger generation, predominantly understood by them as the formation of a child’s personality oriented towards self-responsibility. Conclusion dwells upon the fact that timely educational work with students to promote family values during their university education can adjust the axiological priorities of future teachers and foster their ability to convey representations of the family to a young audience.
Identification of Discourses among Soviet Professionals: Sociological Analysis
Authors:   Herzen State Pedagogical University of Russia, Martianova Natalia A.
Published: April 2024

The article presents a sociological analysis of the discourses of Soviet professionals, as well as the identifica-tion of their antagonism and hegemony. Soviet production brochures containing author’s narratives of profes-sionals of several specialties and industries are analyzed. The sequence of discourse analysis is developed according to the methodological model of E. Laclau and Ch. Mouffe. The following categories are identified: key signs, articulation, moments, elements, domain of discursivity, discourse structure, nodal point, subject, discourse, slippage, antagonism, hegemony. Within the overarching hegemonic Soviet discourse, the following specific discourses are identified: quantitative and qualitative indicators, collectivism and individualism, men-torship and apprenticeship, personal responsibility and public good. Social practices for shaping these dis-courses were identified, as well as mechanisms for forming, maintaining, and preserving the social patterns of Soviet professionals. A generalizing classification of the identified discourses has been developed. Through a rigorous sociological analysis, this study sheds light on the diverse discourses among Soviet professionals and their role within the broader societal context. Furthermore, the developed methodology provides a framework for future studies on discourse analysis in similar socio-political contexts.

Published: April 2024

Objectives: This in-vitro study aimed to determine the best coating technique of nano SiO2 liquid material and its effect on hydrophobicity of thermoplastic partial denture clasp resins. Materials and methods: 80 thermoplastic disc specimens (Acetal, n=40 and Polyamide, n=40) were fabricated. The specimens were randomly divided into 4 subgroups (n=10/group); brush coating, spray coating, dip coating and uncoated as control group. SEM was used to evaluate the surface topography and the spread of coating material. The subjective method, image quality assessment was used to quantify the images’ quality. The mean contact angle was identified by using Image J software. Results: Mean of opinion score of SEM showed that dip-coated specimens of the two tested materials showed the best coating spread quality among the other coating techniques. Image J software measurements revealed that the contact angle of dip-coated acetal and polyamide specimens exhibited the highest contact angle sequentially in comparison to all tested specimens. Conclusion: These results suggest that the dip coating technique has the best results in comparison with the two other coating techniques. Nano SiO2 coating of thermoplastic clasp materials has improved their contact angle which in turn has improved the hydrophobicity of these clasp materials because their external properties are better than those of control specimens. This study will provide a novel external approach for ameliorating thermoplastic partial denture clasp materials using nano SiO2 to enhance their surface properties and solve their limitations and therefore promote the use of these aesthetic clasps.

Kawasan mangrove Desa Margasari mengalami kerusakan akibat abrasi yang tinggi. Pada area ini telah dilakukan penanaman mangrove oleh pengelola. Akan tetapi karena kurangnya pemahaman dan pengetahuan mengenai teknik penanaman dan pemilihan jenis tanaman mangrove berdasarkan kondisi tempat tumbuhnya, sehingga banyak permudaan yang gagal dan mati. Untuk itu tim pengabdian dari Universitas Lampung melakukan kegiatan untuk meningkatkan pemahaman dan keterampilan masyarakat tentang pembuatan bibit mangrove dan cara permudaan kawasan mangrove berdasarkan sistem suksesi alaminya. Metode kegiatan ini meliputi ceramah, diskusi, demonstrasi, dan praktek melalui pemberdayaan masyarakat. Kegiatan ini telah terlaksana dengan baik. Hal ini terlihat dari perbandingan hasil pre dan post test yang menunjukkan peningkatan pengetahuan peserta rata-rata sebesar 43% tentang dinamika vegetasi (suksesi) dan teknik pembibitan tanaman mangrove. Keinginan dan ketertarikan masyarakat dalam pembibitan mangrove juga menjadi hal penting yang tercapai pada kegiatan ini. Masyarakat telah siap dan mau melaksanakan kegiatan pembibitan yang ditujukan untuk rehabilitasi dan pelestarian kawasan mangrove. The mangrove area of Margasari Village is damaged due to high abrasion. In this area, mangrove planting has been carried out by the manager. However, many seedlings fail and die due to a lack of understanding and knowledge of planting techniques and the selection of mangrove plant species based on the conditions in which they grow. For this reason, the community service team from the University of Lampung conducted activities to increase community understanding and skills about making mangrove seedlings and how to propagate mangrove areas based on their natural succession system. The methods of this activity include lectures, discussions, demonstrations, and practices through community empowerment. This activity has been carried out well. It can be seen from the comparison of pre and post-test results, which showed an average increase in participant knowledge by 43% about vegetation dynamics (succession) and mangrove plant nursery techniques. The desire and interest of the community in mangrove nurseries is also an important thing achieved in this activity. The community is ready and willing to conduct nursery activities to rehabilitate and conserve mangrove areas.

OBJECTIVE

To report the clinical outcomes in toy-breed dogs with atlantoaxial instability (AAI) stabilized with patient-specific 3-D-printed titanium plates or polymethyl methacrylate (PMMA), both with the assistance of 3-D–printed drill guides.

ANIMALS

15 client-owned dogs undergoing surgical treatment for AAI between January 1, 2020, and October 31, 2022.

METHODS

The clinical characteristics, diagnostic images, and neurological outcomes of 15 dogs treated for AAI using 3-D–printing technology were reviewed. Postoperative CT images were examined to evaluate the screw placement accuracy in the atlas and axis. Clinical outcomes, including postoperative neurological improvement and screw loosening, were evaluated in dogs treated with a patient-specific titanium plate and those treated with PMMA.

RESULTS

Patient-specific titanium plates (7 dogs) and PMMA (8 dogs) were used for AAI stabilization. The mean follow-up period was 15.2 months (range 7 to 22 months). A reduction of the axis without vertebral canal violation was confirmed on postoperative CT in 14 dogs. The mean deviation from the preoperative planning ranged from 0.30 to 1.27 mm at the insertion and exit points of 84 screws using this method. The neurological grade had improved in each dog postoperatively and at the final follow-up. Screw loosening was noted in 4 dogs in the titanium plates groups without neurological deterioration.

CLINICAL RELEVANCE

Patient-specific 3-D–printed drill guides and titanium plates or PMMA are effective for AAI stabilization in toy-breed dogs, providing accurate guidance.

Authors: Palić Mirko , Kozina Zrinka , Tutek Natalia
Published: April 2024

Background

The startup scene in Croatia has been accelerating in development in the last decade, partly due to the available European Union funds. Organisational culture is one of the main prerequisites for the growth and development of successful startups. Internal marketing is often crucial to reshaping positive organisational culture and fostering innovative employee behaviour.

Objectives

The purpose of this article was to investigate a main characteristic of the startup culture in the Republic of Croatia in order to recommend actions and activities of internal marketing that can help companies achieve their goals faster by engaging and motivating their employees and fostering a positive culture change.

Methods/Approach

Survey research was conducted on a sample of employees of Croatian startups. The main informant approach was used to collect the answers.

Results

The analysis reveals that as startups grow, they enhance gender diversity and opportunities for idea sharing yet face challenges in maintaining autonomy and constructive feedback. Additionally, mentoring, as one of the venues of internal marketing within startups, significantly bolsters adherence to company principles and fosters a culture of constructive problem-solving, highlighting the critical role of mentorship in shaping a positive organisational environment.

Conclusions

Results show that startups in the Republic of Croatia still have an opportunity to develop further and improve employee-focused culture and to apply several internal marketing activities in order to engage and retain their employees, such as internal communication, professional development, employee benefits, employee recognition and employee engagement.
Economic and Environmental Sustainability through Trade Openness and Energy Production
Authors: Elhassan Tomader
Published: April 2024

Background

Energy production plays a major role in the Saudi Arabian economy, but energy production can lead to an increase in environmental pollution.

Objectives:

This study investigated the impact of energy production and trade openness on Saudi Arabia’s economic growth and environmental pollution using annual data from 1970 to 2020.

Methods/Approach:

The fully modified ordinary least squares (FMOLS) and the dynamic ordinary least squares (DOLS) methods were employed to develop two models, including an economic growth model and an environmental Sustainability or pollution model.

Results:

The results of the two tests ensured that both expanding trade openness and increasing energy production led to faster economic growth. Nevertheless, the expansion of trade openness and energy production also led to environmental pollution; hence, the increase in energy production did not support sustainable development.

Conclusions:

Thus, policymakers should develop a green economy strategy to reduce the use of fossil fuels and increase renewable energy in energy production to reduce environmental pollution. Moreover, the Saudi Arabian government should highly promote investment in renewable energy production through trade openness.

Authors: Lubis Fauziah , Nasution M. Iqbal
Published: April 2024

Introduction: During the course of law enforcement, advocates may encounter interventions and face alleged threats and obstruction processes while defending their clients. This is addressed in Article 16 of the Advocates Law and Constitutional Court Decision No. 26/PUU-XI/2013. However, it is important to note that advocates can forfeit this right if they engage in the criminal offense of Obstruction of Justice.
 
Objective: This research aims to explain how an attorney's immunity rights can be forfeited when they engage in the criminal offense of Obstruction of Justice.
 
Method: This research employs a method commonly used in legal academia, focusing on statutory law and conceptual analysis.
 
Results and Discussion: Understanding the importance of immunity rights is crucial for advocates as they carry out their profession. However, it is essential to be aware of the specific conditions that come with the use of these rights.
 
Research Implications: The rules can be found in Article 16 of the Advocate Law. If advocates do not act in good faith and their actions are unrelated to their professional duties, they may be prone to committing acts of obstruction of justice. When fulfilling professional obligations, an advocate must prioritize the client's defense and act accordingly. In Article 16, the concept of good faith entails the fulfillment of professional responsibilities intending to promote justice and safeguard the client's interests following the law.

Esferoides Celulares: Imitando al Cáncer
Authors: Corzas Avilez Michell Irais , Juárez Aguilar Enrique
Published: April 2024

El desarrollo de la agricultura se remonta al periodo neolítico; el trigo y la cebada fueron las primeras plantas cultivadas por los seres humanos, marcando el fin de la era nómada. Sin embargo, con toda seguridad, un humano de aquel lejano periodo jamás hubiera creído que, además de plantas, lograríamos cultivar nuestras propias células.
El cultivo no se limita a las frutas y a las verduras, pues en un laboratorio con la infraestructura adecuada es posible cultivar células, inclusive las cancerosas. Hasta ahora, los laboratorios emplean células extraídas de tumores humanos, mismas que se suspenden en un medio nutritivo para, posteriormente, ser sembradas sobre la superficie de plástico de un frasco o caja Petri, formando una monocapa de células adheridas. A este tipo de cultivo se le conoce como cultivo celular bidimensional o 2D, y es el modelo de estudio más común empleado en la investigación contra el cáncer.
El cultivo celular 2D se halla detrás de cada medicamento quimioterapéutico actual contra el cáncer, debido a que constituye una de las primeras fases en el desarrollo de nuevos fármacos. Durante esta etapa, las células cancerosas son utilizadas para probar el potencial terapéutico de nuevas moléculas a través de su efecto sobre la supervivencia y proliferación celular. No obstante, pese a que el cultivo 2D de células de cáncer ha contribuido extensamente en el desarrollo de la quimioterapia contra el cáncer, éste constituye un modelo poco realista de la estructura del tumor canceroso.
Como es evidente, las células cultivadas bidimensionalmente no logran representar las características de un tumor sólido, empezando por el hecho de que un tumor no es plano, sino tridimensional, es decir, posee volumen. Esta diferencia constituye una brecha entre los bioensayos realizados en cajas y frascos de cultivo, y lo que en realidad sucede en el tumor de un paciente.
Debido a la imperativa necesidad de cerrar esta brecha, los científicos han desarrollado un tipo de cultivo que permite obtener una esfera de células cancerosas, la cual crece de forma tridimensional, de manera muy similar al desarrollo de un tumor. Esta esfera o esferoide, está constituido por la agrupación de numerosas células cancerosas simulando de mejor manera, aunque incompleta, la estructura de un tumor real. Los esferoides de células cancerosas permiten estudiar características representativas del cáncer como la comunicación y la migración celular, el papel que desempeñan algunas proteínas en el tumor, y el comportamiento celular frente a estímulos físicos; asimismo, permiten evaluar, de manera más fidedigna, el efecto de nuevos fármacos sobre las células cancerosas. Por lo anterior, el cultivo de esferoides constituye una útil herramienta en el estudio del cáncer de forma más realista, permitiéndonos estar más cerca de poder estudiar, dentro de un laboratorio, una enfermedad tan compleja como el cáncer.

Una de las actividades del Observatorio de la Cafeticultura Veracruzana (OBSERVA-CAFÉ) es dar seguimiento al monitoreo y generación de información de las condiciones agroclimáticas de sistemas de producción de café del estado de Veracruz. Por lo que este trabajo tuvo como objetivo analizar las condiciones higrotermométricas, a diferentes escalas temporales, en dos sistemas de producción de café de café bajo sombra: 1) Café-Nacaxtle (CE) y 2) Café-Chalahuite (CI). Se encontró, a escala anual, condiciones más cálidas y secas en el sistema productivo CI en comparación con CE. En la escala de análisis por temporadas, es más evidente durante DEF (temporada diciembre a febrero). Además, de acuerdo con los valores diurnos del DPV (déficit de presión de vapor), las plantas de café en ambos sistemas estudiados experimentaron periodos de déficit hídrico durante la temporada marzo a mayo (MAM). Esto podría ayudar a planear estrategias de mitigación del déficit hídrico, de acuerdo con las características particulares de cada sistema productivo, durante MAM.
 
Hygrothermometrical conditions in two coffee production systems: Period March 202–February 2023
Abstract: One of the activities of the Observatory of Veracruz Coffee Growing (OBSERVA-CAFÉ), is to follow up on the monitoring and generation of information on the agroclimatic conditions of coffee production systems in the state of Veracruz.  Therefore, this work aimed to analyze the hygrothermometric conditions at different time scales in two shade-cast coffee production systems; 1) Café-Nacaxtle (CE) and 2) Café-Chalahuite (CI). On an annual scale, warmer and drier conditions were found in the CI production system compared to EC. On the scale of analysis by seasons, it is most evident during DEF (season December to February). In addition, according to the diurnal values of the DPV (vapor pressure deficit), coffee plants experience periods of water deficit during the March to May season (MAM), in both systems studied. This could help to plan specific mitigation strategies, according to the particular characteristics of each production system, during MAM.

In this context, the Grijalva and Usumacinta River basins (CGyU), shared by Mexico, Guatemala, and Belize, stand out for their water abundance, natural richness, and high vulnerability to extreme hydrometeorological events. The main objective of this research is the geomorphometric characterization of the CGyU. For this purpose, hierarchical classification was developed using Hammond's method and the process was automated using Geographic Information Systems (GIS) adapted by Dikau. The results revealed the existence of five main classes and eighteen subclasses of landforms in both watersheds. Based on these findings, we can conclude that the methodology employed proved to be reliable for describing landforms in these watersheds. Therefore, this study contributes to new research and the implementation of public policies related to land use planning, civil protection, and biodiversity, among others.

Objective:

Tuberculosis (TB) remains a major health problem, especially in the developing countries. Fine-needle aspiration cytology is the first line of investigation for tubercular lymphadenitis as it is easy to perform, less invasive, quick, and economical. The typical cytopathological features of tuberculosis TB include epithelioid cell granulomas with Langhans giant cells and caseous necrosis. The present study aimed to evaluate the cytomorphological features of newly diagnosed cases of tubercular lymphadenitis confirmed by GeneXpert.

Material and Methods:

This was a retrospective study in which all fine-needle aspirates from newly diagnosed cases of tubercular lymphadenitis confirmed by GeneXpert over a 1-year period from July 2022 to July 2023 were included in the study. The May–Grunwald–Giemsa stained smears from these aspirates were categorized into three patterns-epithelioid cell granulomas with necrosis, epithelioid granulomas without necrosis, and necrosis only. The granulomas were further categorized into well-formed, ill--formed, and splintered. The background of the aspirate which included a reactive lymphoid background, lymphocytes, eosinophils, and neutrophils was tabulated for all the cases.

Results:

Out of the three cytomorphological patterns, epithelioid granulomas with necrosis were the most predominant (67.5%), followed by necrosis only (20.8%) and granulomas without necrosis (11.6%). An acid-fast bacilli (AFB) positivity of 53.3% (64 cases) was seen on the Ziehl-Neelsen stain. Well-composed, poorly formed, and splintered granulomas were seen in 55 (57.9%), 42 (44.2%), and 21 (22.1%) cases, respectively. Neutrophils were the most common background population (42, 35%) followed by lymphocytes (36, 30%). Reactive lymphoid cells and eosinophils were seen in 12 (10%) and 3 (2.5%) cases, respectively.

Conclusion:

Fine-needle aspiration cytology is a rapid inexpensive minimally invasive test for tubercular lymphadenitis as epithelioid cell granulomas along with caseous necrosis are highly suggestive of TB. However, manual acid-fast AFB detection has a low sensitivity as is illustrated in the present study where only AFBwas demonstrated in only 53.3% of cases.

A 47-year-old female presented with dyspnea, dry cough, and fatigue for ten days. On examination, she had severe pallor and bilateral crepts in the lungs. Complete blood count (CBC) showed a hemoglobin of 7.3 g/dL, reticulocyte count of 5.6%, and chest X-ray was normal. Her extended Direct Coombs test (DCT) showed C3d +3 and cold agglutinin titer of 1:256 at 4°C. A comprehensive respiratory panel showed positivity for Mycoplasma pneumonia. Thus, a diagnosis of cold agglutinin syndrome secondary to M. pneumonia was made, and she was started on injection doxycycline 100 mg IV twice a day, following which her symptoms and anemia improved without transfusion support.
Mixing order asymmetry in nanoparticle-polymer complexation and precipitation revealed by isothermal titration calorimetry

In recent years, there has been a renewed interest in complex coacervation, driven by concerted efforts to offer novel experimental and theoretical insights into electrostatic charge-induced association. While previous studies have primarily focused on polyelectrolytes, proteins or surfactants, our work explores the potential of using cerium (CeO2) and iron (γ-Fe2O3) oxide nanoparticles (NPs) to develop innovative nanomaterials. By combining various charged species, such as polyelectrolytes, charged neutral block copolymers and coated NPs, we study a wide variety of complexation patterns and compare them using isothermal titration calorimetry, light scattering and microscopy. These techniques confirm that the titration of oppositely charged species occurs in two steps: the formation of polyelectrolyte complexes and subsequent phase (or microphase) separation, depending on the system studied. Across all examined cases, the entropic contribution to the total free energy surpasses the enthalpic contribution, in agreement with counterion release mechanisms. Furthermore, our investigation reveals a consistent asymmetry in the reaction enthalpy associated with the secondary process, with exothermic profiles observed upon the addition of cationic species to anionic ones and endothermic profiles in the reverse case.

Ligand engineering is one of the most important, but labor-intensive processes in the development of transition metal catalysis. Historically, this process has been streamlined by the invention of ligand descriptors such as Tolman’s electronic parameter and the cone angle. Analyzing reaction outcomes in terms of these parameters has enabled chemists to find important factors for designing optimal ligands. However, typical strategies for these analyses largely rely on regression approaches, which often requires many experimental data to understand non-intuitive trends. Here, we introduce the virtual ligand-assisted optimization (VLAO) method, a novel computational approach for ligand engineering. In this method, important features of ligands are identified by simple mathematical operations on equilibrium structures and/or transition states of interest, and derivative values of arbitrary objective functions with respect to ligand parameters are obtained. These derivative values are then used as a guiding principle to optimize ligands within the parameter space. The VLAO method was demonstrated in the optimization of monodentate and bidentate phosphine ligands including asymmetric quinoxaline-based ligands. In addition, we successfully found a highly selective ligand for the α-selective hydrogermylation of a terminal ynamide according to the suggested design principle by the VLAO method. These results would imply the potential utility of the VLAO method in optimizing wide variety of ligands in transition metal catalysis.
