Abstract
An iridium-192 miniature sealed source was produced by irradiation of 12 metal disks of natural iridium (470.5 mg) under a thermal neutron flux of 9.4 × 1013 n cm−2 s−1 during 200 h in Es Salam research reactor (Algeria). The preliminary activity was measured after 10 days decay time by a CAPINTEC type CRC-712 M dose calibrator, the given activity was 1.9 × 1011 Bq (5.2 Ci). To estimate source activity, a modeling of reactor core and irradiation container with the targets was made by MCNP5 code with and without iridium targets to evaluate the effect of the disturbance and reaction; the calculated activity using disturbed flux was comparable with that measured. A non-destructive test using 192Ir sealed sources with GammaMat TSI type B(U) projectors was carried out to evaluate the integrity of the weld joint at the bend of a carbon steel pipe. The weld quality of two plates; carbon steel and stainless steel was also evaluated. In terms of sensitivity, the resulting gamma images matched well and reported a real finding on the state of tested samples.

Abstract
A new cobalt(II) compound with the formula [Co(5-Br-pyc)(2,2′-bipy)(H2O)(Cl)]·2H2O (1·H2O) (5-Br-Hpyc = 5-bromo-pyridine-2-carboxylic acid, 2,2′-bipy = 2,2′-bipyridine) has been hydrothermally synthesized and well characterized. The X-ray single-crystal diffraction analysis showed that 1⋅2H2O has crystallizes in the monoclinic system, space group P21/c (no. 14). The Co(II) center was octahedrally bonded by one bidentate chelate 5-Br-pyc anion and one 2,2′-bipy, one water molecule as well as one chloride anion to form the mononuclear structure of 1⋅2H2O. Complex 1⋅2H2O forms a 3D network through abundant O–H⋅⋅⋅O hydrogen bonds and π⋅⋅⋅π stacking interactions. Notably, the 5-Br-Hpyc ligand was in situ generated by decarboxylation of the 3-bromo-pyridine-2,6-dicarboxylic acid (3-Br-H2pydc) precursor selectively on 2-position under hydrothermal conditions. The magnetic properties, the Hirshfeld surface structure and the synthetic process for 1⋅2H2O have been carefully described and discussed.
Luxación medial y plantar del hueso navicular asociada a fractura-subluxación calcaneocuboidea. Presentación de un caso
Authors: Seletti Maximiliano , Parma Julián 
Published: February 2023

Las luxaciones del escafoides aisladas y sin fractura son poco frecuentes. Por lo general, se presentan asociadas a fracturas del escafoides o a diversos patrones de lesión de la columna lateral. Presentamos el caso de un paciente con luxación medial y plantar del hueso navicular y fractura conminuta del proceso anterior del calcáneo y subluxación calcaneocuboidea. En el Servicio de Urgencia, se procedió a la reducción cerrada y la estabilización con agujas de Kirschner y, como tratamiento diferido, se colocaron placas en puente astragalonaviculo-cuneiforme y calcaneocuboidea de 2,0 mm, en forma transitoria, y el material de osteosíntesis se retiró a los 5 meses. El puntaje de la escala de la AOFAS fue excelente al año de seguimiento.
Conclusiones: Es necesario llegar a un diagnóstico adecuado descartando lesiones de la columna lateral y reducir esta lesión en la atención de urgencia. La estabilización con placas en puente es una opción válida que podría evitar la pérdida de la reducción que se observa al retirar los clavos de Kirschner y permite una carga precoz.

Authors: Villena Daniel Sebastián , Valenti Pablo , Verbner Jonathan , Sotelano Pablo , Santini Araujo María Gala , Conti Leonardo , Parise Ana Cecilia , Carrasco Marina 
Published: February 2023

Introducción: El objetivo principal fue evaluar la relación entre la formación de calcificaciones heterotópicas y los parámetros de alineación de la prótesis.
Materiales y Métodos: La población estaba formada por 31 pacientes. Se evaluaron variables radiográficas de alineación, como ángulos alfa y beta, centro de rotación astragalino y el porcentaje de cobertura posterior de la tibia en el posoperatorio inmediato y a los 2 años. Las variables de evaluación clínica fueron: la escala analógica visual y la escala de la AOFAS, y el cuestionario SF-36 para evaluar la calidad de vida al final del seguimiento.
Resultados: La etiología más frecuente de la artrosis fue la postraumática (67,7%). En el posoperatorio inmediato, el ángulo alfa promedio fue de 88,7° (rango 82-92,6; DE ± 2,61); el ángulo beta, de 84,46° (rango 78,62-91,40; DE ± 3,59). La alineación del componente tibial en el plano frontal fue neutra en 25 pacientes (80,6%), en valgo en 6 (19,4%) y en varo (0%). A los 2 años de seguimiento, el 96% tenía calcificacionesheterotópicas. Mejoraron los puntajes en la escala de la AOFAS (preoperatorio/posoperatorio: 31,90/80,94) y en la escala analógica visual (preoperatorio/posoperatorio: 8,7/1,97) (p <0,05).
Conclusiones: No se halló una relación entre calcificaciones heterotópicas y peores resultados funcionales ni de dolor, excepto en los parámetros de calidad de vida (SF-36), como el rol físico, la limitación emocional y la percepción de la salud general, que empeoraron a medida que aumentó el grado de calcificacionesalrededor de la prótesis.

Introducción: La lesión del ligamento calcaneonavicular ha sido descrita como una de las causas de la deformidad en el pie plano del adulto. El objetivo de este artículo es describir portales modificados para el diagnóstico y la reparación endoscópica de las lesiones del fascículo superomedial del ligamento calcaneonavicular y evaluar la seguridad de los portales utilizados.
Materiales y Métodos: Se llevó a cabo un estudio cadavérico con seis preparados reproduciendo una lesión del fascículo superomedial del ligamento calcaneonavicular con una punta de corte de radiofrecuencia y la posterior reparación endoscópica. Se crearon dos portales modificados para el abordaje. Luego se procedió a la disección anatómica para evaluar la seguridad de los portales en relación con las estructuras anatómicas. El primer portal se realiza inmediatamente proximal a una línea trazada desde la punta del maléolo medial dirigida al centro del talón, el segundo portal se emplaza 0,5 cm proximal a la inserción del tendón tibial posterior en el escafoides por transiluminación. Si es necesario, se coloca un portal accesorio inmediatamente dorsal al tendón tibial posterior a mitad de camino entre los dos portales antes descritos.
Resultados: En todos los casos, fue posible la reparación del ligamento con el procedimiento endoscópico. En la disección anatómica de los portales, se observó una distancia promedio a las estructuras vasculonerviosas de 11,83 mm del portal proximal y de 9,66 mm del portal distal.
Conclusión: Los portales modificados son seguros y permiten la visualización directa del haz superomedial del ligamento calcaneonavicular y su reparación endoscópica.

Introduction. The study of the basic characteristics of the sociocultural identity of a modern student as value and semantic foundations of personal development is relevant due to the cultural and moral transformations of modern society and the practical need to change the system of education in higher education.Aim. The current research aims to reveal the sociocultural characteristics by which a modern student describes himself/herself when compared with a group and to identify groups, communities, which is the subject of identification for the student.Methodology and research methods. The authors used a quantitative approach to the collection and analysis of the data obtained. This made it possible to cover a large sample and obtain statistically reliable results. The theoretical methods of research were historiographical and comparative types of analysis (allowed to formulate the initial provisions of the study); conceptual and terminological analysis of philosophical, psychological, psychological-pedagogical, socio-psychological literature (used to describe the categorical field of the problem); systematisation and conceptualisation of scientific ideas. The following empirical methods were applied: questionnaires, testing. Data processing methods: methods of mathematical statistics (descriptive statistics, Student’s T-test, one-factor analysis of variance).Results. The article contains the results of an empirical study of the sociocultural identity of students. The authors defined the foundations of the ideas of modern youth about themselves. In particular, students describe themselves through belonging to family, profession, gender and national groups. The authors identified the groups with which the respondents identify themselves: this is a family and a circle of friends. Moreover, the authors revealed that the socio-cultural identity of students has gender, age differences, and depends on the direction of training at the university. The role of the presented results in the modern international scientific discourse was analysed.Scientific novelty. The authors conceptualised the concept of sociocultural identity and described the mechanisms of its formation; identified the main components in the structure of sociocultural identity of young people; established gender, age and educational differences in the characteristics of sociocultural identity of students; identified dominant groups in the process of identification of a young person with a high degree of significance.Practical significance. The results of the study can be used as a spiritual and moral, value-oriented basis of the education programme in higher education.

Authors: Kicherova M. N. , Trifonova I. S. 
Published: February 2023

Introduction. Non-formal education is gaining a new impetus in the establishment of a sustainable knowledge society. The article reveals major concerns of non-formal education as an element of life-long learning and adult education policies as well as its effective implementation into the national educational mainstream.Aim. The aim of the research is to conduct a detailed overview of various current studies, exemplifying the international experience in non-formal education and the case-studies of its adoption along with the mechanisms for its validation in different countries.Methodology and research methods. The work was based on the methodology of comparative analysis and qualitative content analysis of official UNESCO, CEDEFOP, etc. international statistical and analytical reports, academic and empirical studies. An analytical review shows policy changes towards the development of non-formal education as well as an international and available in individual countries experience of its studying and implementation.Results. Based on the compatibility scopes principle, three levels of analysis of non-formal education (macro-level/global, meso-level/institutional, micro-level/personal) were identified so that the key issues and trends in its development could be pinpointed at every stage. The conducted research leads to the conclusion that non-formal education practices are acquiring institutional forms. The level of non-formal education development in different countries varies. However, there are general trends towards solving a number of similar social problems by means of non-formal education, such as bridging the supply and demand for competencies in the labour market, social inclusion of different segments of the population, and others.Scientific novelty and practical significance. The novelty of this study is seen in the resource capacity of non-formal education, the potential of its implementation for the vocational re-skilling, upskilling and further training of various socio-demographic groups, its global development trends and prospects. The practical significance lies in the application of mechanisms for recognising non-formal education outcomes. The highlighted trends and the best international experience can provide non-formal education integration into the educational mainstream, create experimental learning platforms and accelerate practical educational policy measures.
