ENSURING THE CONTINUITY OF MILITARY TRANSPORTATION IN THE EVENT OF FAILURE OF TRANSPORTATION FACILITIES
Authors: HUDIMOV V. V. , MAKSYMENKOV YE. A.
Published: December 2022

Purpose. The purpose of the work is to conduct an analysis of the organization of the continuity of military transportation in the conditions of the conduct of hostilities by the Armed Forces of Ukraine. Currently, the issue of the interaction of different types of transport in the conditions of failure of important transport infrastructure facilities is important. Methodology. To date, the Armed Forces of Ukraine have created a system of transportation of material resources, which mainly meets the needs of the troops involved in the execution of tasks in combat operations. An analysis of the organization and implementation of military transportation was carried out to find out ways to solve problematic issues related to the implementation of military transportation during the preparation and conduct of combat operations, which affect the quality of their implementation. Findings. In the case of the destruction of certain transport facilities (railway bridges), the military transport plan is refined with the dispatch of military echelons by detour routes. If it is not possible to continue transportation by rail, the military echelons are unloaded and regrouped in the assembly areas to continue moving on their own to the destination areas or to new loading areas. The basis for the development of the technological process of the TTA (temporary transshipment area) operation should be the schedule of feeding and cleaning of cargo and empty trains at the unloading (loading) station. Originality consists in solving the problem of choosing the optimal option for the transfer of military echelons and transports through the TTA. One of the most important elements of the TTA is the adjacent water area with ferry crossings (floating bridges) from river floats. Carrying out calculations for the transfer of troops and cargo through the TTA provides an opportunity to choose the option of rational use of road and pipeline transport, as well as minimal expenditure of motor resources when routing military echelons from the unloading station to the loading station. Practical value. According to the conducted analysis, recommendations were given regarding the preservation of the network of logistical support of units in a special period, specifically the survivability of transport facilities. It is possible to formulate further directions of scientific research, to create a rational system for the location of technical cover units of the most vulnerable transport objects, as well as for their rapid restoration in case of destruction.

Viabilidad de la ordeña y el pajarete como recursos agroturísticos en los municipios de Zapotlán el Grande y Gómez Farías, Jalisco (México)
Authors: Ibarra Jorge Arturo
Published: December 2022

Se presenta un diagnóstico realizado en los municipios de Zapotlán el Grande y Gómez Farías, Jalisco para identificar las características de la producción y venta de la bebida denominada pajarete (leche recién ordeñada de vaca, chocolate y alcohol de caña) y la posibilidad de considerarla como un recurso agroturístico. Se realizó un proceso de investigación documental de archivos y registros municipales, trabajo de campo de carácter etnográfico mediante la observación participante y la aplicación de entrevistas semiestructuradas con los productores para identificar las características del proceso productivo y las condiciones de las instalaciones. Los resultados muestran la situación de los establos; el manejo del ganado; el proceso de la ordeña y las características de la venta al público. Se concluye que la venta del pajarete ha complementado la economía de los pequeños productores lecheros y que es posible considerarlo como un potencial recurso turístico, pero requiere un mayor control de calidad en el proceso de ordeña, un mejoramiento de la infraestructura existente y un incremento de la calidad del servicio a los usuarios.

A Prayer Phrase on the Doublures Cover of the Principalities Period Turkish-Islamic Bindings: Al-‘izz al-dā’im wa’l-iqbāl
Authors: BOYDAK Fatma Şeyma
Published: December 2022

The phrases of prayer on the Turkish-Islamic bindings of the Principalities period are among the subjects that have been studied at least. The subject of this article is the Al-‘izz al-dā’im wa’l-iqbāl phrases inside the covers of the Turkish-Islamic bindings produced in the Principalities period, which has not been the subject of a scientific study until now, and the pattern composition containing this phrase. Al-‘izz al-dā’im wa’l-iqbāl translates as everlasting power and prosperity/high position. As a result of the research, this phrase was found on the cover of six manuscripts of the Principalities period (Amasya ML: 217, İnebey ML Hüseyin Çelebi: 481 and Ulu Cami: 318, Kastamonu ML: 2856 and 3435 and Süleymaniye ML Fatih: 5004). The cover inside pattern of the bindings is a full-ground geometric design decorated with floral and rūmī motifs. This prayer phrase is written on the hexagonal sheets inside the geometric pattern. The phrase has been designed and written in two types as single line and double line reverse symmetrical. The inscription was found on books and various objects (bowl, ewer, cup, etc.) belonging to important people in the Seljuk, Anatolian Principalities, and early Ottoman periods. It is thought that this phrase is a phrase of prayer wishing that power and high position will be permanent, and that the addressee of the prayer is the sultan, a person belonging to the sultanate or a person who took part in important levels of the state. The waqf seals and records of the individuals on the works also support this.
Teşbih Beyan İlminin Neresindedir: Klasik Yaklaşım Üzerine Bir İnceleme
Authors: İNCE Nazife Nihal
Published: December 2022

Bu çalışma, teşbihin beyan ilmi içerisindeki yerini klasik belagat çalışmaları üzerinden araştırmayı amaçlamaktadır. Klasik kabulde beyan ilminin; teşbih, mecaz ve kinaye olmak üzere üç temel konusu bulunmakta ve söz sanatları bu konuların altında ele alınmaktadır. Beyan ilmi içerisinde mütalaa edilen söz sanatları, ekseriyetle, anlamına çıkarım yoluyla ulaşılan ifade biçimleridir. Şu var ki teşbihte anlama ulaşmak için çıkarıma gerek duyulmaz. Öte yandan teşbihin beyan ilmi içerisindeki konumuna ilişkin mevcut kabulü nakzeden ifadeler bulunmaktadır. Çalışmamız, belagat literatüründe tartışılan hakikat-mecaz ayrımının beyan ilminin konularını belirleyen bir kıstas olduğunu savunmakta ve bu savı gerekçelendirmek üzere üç hususu dikkate almaktadır. Bunlar: klasik çalışmaların belagati alt dallara ayırmada esas aldığı belirleyici özellikler, teşbihi tanımlamada kullandığı parametreler ve son olarak hakikat-mecaz ayrımında kullandığı parametrelerdir. Araştırmamızın başlıca sonucu: klasik yaklaşımın teşbihi, söze kattığı güzellik ve ikna edicilik açısından özel bir ifade türü kabul ettiği ancak beyan ilminde yer alan diğer söz sanatları gibi çıkarıma dayalı anlatım biçimlerinden kabul etmediğidir. Klasik belagat literatürü, teşbihin istiarenin zeminini oluşturan bir konu olduğunu açıkça ifade ederken aynı açıklığı teşbihin doğrudan anlatım olduğunu ifade etme konusunda göstermemiştir.
Technology and strategy use in academic writing
Authors: Bakla Arif , Karakaş Ali
Published: December 2022

This study investigates the practices of native, native-like and non-native speakers of English in academic writing. The researchers developed and validated a survey with Likert items. The items in the survey were created using the researchers’ personal experience, the literature and an open-ended survey with three items administered to 31 researchers. The resulting survey was validated through cognitive interviewing and piloting with 30 respondents. The survey conducted with 190 participants provided comparative insight into how the three groups differ in their use of technology, strategies and dictionaries along with challenges they faced in academic writing. The results globally indicated that non-native speakers used strategies more frequently than native-like English speakers or native speakers. Similarly, the integration of technology into academic writing process and dictionary use were a favourite activity among the non-native speakers. However, all three groups of researchers experienced similar challenges in academic writing, which globally suggests that language per se is not enough for success in scholarly writing and publishing.

Keywords: academic writing, native speakers, non-native speakers, strategies
Infiriendo el efecto de factores abióticos sobre la temperatura corporal y pérdida de agua sobre modelos de agar de la rana sabanera (Dendropsophus molitor) en Cajicá- Cundinamarca
Authors: Acosta Lugo Estefany , Galindo Uribe Diana María , Bracho Altamiranda Faidith , Pinto Sánchez Nelsy Rocio
Published: December 2022

La alta permeabilidad de la piel representa una restricción fisiológica en anfibios, debido a un mayor riesgo de deshidratación por evapotranspiración en ambientes con menor disponibilidad de agua y mayor temperatura. Dendropsophus molitor es una especie semiacuática con comportamiento de tomar el sol, mecanismo termorregulatorio, necesario para llevar a cabo sus procesos vitales. El objetivo de este trabajo fue evaluar el efecto de las variables ambientales, tipo de microhábitat y color, sobre la temperatura corporal y pérdida de agua en D. molitor. Para esto, se usaron modelos de agar de dos colores, ubicados en dos tipos de microhábitat (húmedo vs. seco), cada uno en dos condiciones de exposición (sol vs. sombra), midiendo el porcentaje de cambio de peso y temperatura corporal. Se realizaron análisis estadísticos como correlación, modelos de efectos lineares mixtos, y el método del factor de inflación de la varianza. Los resultados del estudio mostraron que el punto de rocío, la humedad relativa, la radiación solar, la temperatura del sustrato y el microhábitat, pero no el color de los modelos de agar, tuvieron un efecto significativo sobre el porcentaje de cambio de peso y la temperatura corporal. Ambas variables incrementaron en la condición microhábitat seco y sol, así como en seco y sombra, entre las 12:00 y 16:00 horas. La evapotranspiración está íntimamente relacionada con la radiación y el déficit de presión de vapor, siendo importante para la temperatura corporal del anfibio, debido a que éste se enfría mediante la evapotranspiración del agua a través de su piel.  Por último, se sugiere que las variables a nivel del microhábitat son vitales para estas especies, y deberían ser incorporadas en este tipo de estudios.
Effects of initial stress anisotropy on the onset of undrained instability for Guamo sand
Authors: Prada-Sarmiento Luis Felipe , Ramos-Cañón Alfonso Mariano , Camacho-Tauta Javier
Published: December 2022

Undrained instability is a failure mode that has been observed in many sandy slopes. However, the highly anisotropic stress states caused by the geometry of the slope have not been duly considered from the experimental point of view. This article studies the influence of the initial stress anisotropy of laboratory samples on the static undrained instability of the Colombian reference sand. Forty-five consolidated undrained triaxial tests were performed, prescribing combinations of different initial void ratios, mean confining pressure, and initial stress ratios. Experimental results allow concluding that: a. the size of the instability zone on the p′ − q plane becomes smaller for larger initial anisotropic stress ratios; b. a novel undrained instability plane can be proposed in the p′ − q − e space to set a boundary between stable and unstable undrained loading conditions; c. mean confining pressure plays a vital role in the estimation of undrained instability for Guamo sand samples under low and medium confining stresses; d. despite multiple factors that influence the onset of undrained instability, a relation can be derived between the undrained instability susceptibility of sandy slopes and the initial stress ratio η0.

Published: December 2022

Objetivo: Estimar la seroincidencia acumulada de inmunoglobulinas (Ig) clase G (IgG) anti-SARS-CoV-2 en trabajadores de la salud asintomáticos y su asociación epidemiológica dentro de las áreas funcionales del Hospital Departamental de Villavicencio (HDV).
Metodología: Se llevó a cabo un estudio observacional analítico longitudinal de una cohorte de trabajadores, donde cada 21 días, en tres oportunidades, se midieron IgG anti-SARS-CoV-2 en suero sanguíneo, a través de ELISA indirecto, en una muestra representativa aleatoria (n = 105) de trabajadores sanitarios del hospital (N = 756). Como instrumento de recolección de datos se utilizó una encuesta, donde cada trabajador sanitario declaró no haber sido diagnosticado con COVID-19, e igualmente registró la información sobre las variables independientes: sexo, edad, condición laboral, área funcional y comorbilidades.
Resultados: La prevalencia inicial para SARS-CoV-2 entre los trabajadores sanitarios asintomáticos del HDV fue de 9,52 % (IC 95 % 5,25-16,65). La seroincidencia acumulada durante 42 días fue de 12,38 % (IC 95 % 7,38-20,04). El riesgo relativo (RR) se utilizó para establecer los factores de riesgo asociados a las variables independientes. El sexo masculino (RR ajustado = 3,34, IC 95 % 1,98-5,86), obesidad (RR ajustado = 10,98, IC 95 % 1,41-85,98) y sexo femenino (RR ajustado = 2,15, IC 95 % 1,12-4,31) en las áreas funcionales de Hospitalización, Medicina Crítica y Urgencias, respectivamente, son factores de riesgo en el HDV.
Conclusión: Un total de 13 de 105 trabajadores sanitarios del hospital seroconvirtieron positivamente para SARS-CoV-2 y fueron asintomáticos durante 42 días de seguimiento epidemiológico. Además, existen factores de riesgo importantes en su exposición a este virus en el HDV.

Objetivo: Describir la prevalencia del parto adolescente por cohorte a través de los años y su relación con factores sociodemográficos, en Panamá.
Metodología: A partir de un análisis secundario de la “Encuesta nacional de salud sexual y reproductiva 2014-2015” de Panamá, utilizando cohortes por año de nacimiento (1966-1975, 1976-1985, 1986-1995 y 1996-2000), la relación enunciada se analizó mediante regresión logística. Se incluyeron 4795 adultas (20-49 años) y 821 adolescentes (15-19 años).
Resultados: Se encontró un aumento en la prevalencia del parto adolescente entre cohortes, donde la prevalencia fue de 30,9 % en la cohorte mayor (1966-1975) y de 51,5 % en la cohorte de 1986-1995. En todas las cohortes, el parto adolescente estuvo asociado a la ruralidad (1966-1975, 42,3 % rural no indígena; 1976-1985, 56,6 % rural indígena; 1986-1995, 65,4 % rural no indígena y 58,2 % rural indígena). En todas las cohortes, el parto adolescente se relacionó con menor bienestar, encontrándose una prevalencia mayor que el 40 % en el quintil menor de riqueza en todas las cohortes. El parto adolescente se asoció a tener 4 o más hijos en las cohortes mayores (1966-1975 y 1976-1985), con prevalencias mayores que el 63 %.
Conclusiones: La prevalencia del parto en adolescente en Panamá se ha mantenido en crecimiento. Las poblaciones rurales y de menor bienestar se han mantenido con mayor prevalencia de parto adolescente, indicando dónde enfocar las intervenciones preventivas.
Idoneidad del profesorado de religión y autonomía confesional en el caso Pavez: la postura de la Corte Interamericana frente a la doctrina del Tribunal de Estrasburgo
Authors: López-Sidro López Ángel
Published: December 2022

La designación del profesorado que da clases de religión en un centro educativo público implica una intervención decisiva de la confesión religiosa a la que pertenece, pues el principio de neutralidad hace incompetente al Estado para valorar la idoneidad del profesorado que ha de impartir esa enseñanza. Esta práctica, extendida en varios países y reconocida en importantes sentencias del Tribunal Europeo de Derechos Humanos, ha sido cuestionada en la Sentencia de la Corte Interamericana de Derechos Humanos en el caso Pavez contra Chile. En el presente análisis, se examinan los argumentos que apartan esta resolución de la doctrina más extendida internacionalmente y se confrontan con los que ponen el acento en los derechos fundamentales vinculados al factor religioso: la autonomía para que las confesiones ejerciten su libertad religiosa y los derechos de los padres sobre la educación de sus hijos.
soft law como parámetro formal de la vehiculación de los Derechos Humanos en el derecho positivo
Authors: Ariza Ugalde Eduard
Published: December 2022

La naturaleza, fundamentos y positivación de los Derechos Humanos (DDHH) siempre son cuestiones controvertidas. En este artículo nos centramos en analizarlas de manera conjunta, prestando especial atención al aspecto formal de los DDHH como integrantes de la legalidad de un ordenamiento jurídico, sea estatal o internacional. Atendiendo a que los tribunales y administraciones públicas pueden aplicar el soft law, a modo de parámetro interpretativo y como medio de colmar lagunas o para concretar conceptos jurídicos indeterminados, haciéndolo así de facto obligatorio, abogamos por erigirlo en parámetro formal mínimo para admitir la existencia de la legislación positiva de los DDHH, más allá de las meras directrices políticas.
Aspectos jurídicos de la lucha contra la importación de vinos españoles e italianos en Francia a finales del siglo XIX
Authors: Serra Olivier
Published: December 2022

Durante los últimos veinte años del siglo XIX, Francia emprendió la reconstrucción de un viñedo asolado por la filoxera. Al mismo tiempo, pretendía poner fin a la importación de vinos italianos y españoles, ya que éstos contribuían a la saturación del mercado nacional y alimentaban algunos fraudes sobre la composición y el origen de los vinos franceses de consumo corriente. En la actividad legislativa de este periodo destaca la denuncia de los tratados comerciales firmados con Italia y España a principios de la década de 1880. Estos instrumentos de libre comercio ya no parecían corresponder a las expectativas de una viticultura muy bien representada en el Parlamento. Por el contrario, era el momento de promover la política arancelaria, de la que las leyes del 11 de enero de 1892 y del 1 de febrero de 1899 eran las piedras angulares, en contra de los intereses del comercio del vino. Al desalentar considerablemente la competencia italiana y española, el proteccionismo vitivinícolo francés dejó su huella en las relaciones comerciales del país hasta el establecimiento del mercado común.
Judicialização do direito à saúde na área de neoplasias: entendimentos do Tribunal de Justiça do Estado do Rio Grande do Sul
Authors: Quevedo André Luis Alves de
Published: December 2022

Objective: to know how the Court of Justice of the State of Rio Grande do Sul, Brazil, positions itself from January 2019 to March 2020 in relation to the right to health, specifically about neoplasms. Methods: this is an empirical study with a quantitative and qualitative approach that examines the jurisprudence in the form of a compilation. The data were extracted, systematized, and analyzed, using as selection criteria the saturation of the data and the sufficiency of the theoretical arguments in relation to the objective of this study. Results: 344 cases decided in second instance were analyzed. In the quantitative analysis, it was found that most of the cases came from the Porto Alegre Court and were decided by judgment, with a low percentage of reform of first instance decisions. In the qualitative analysis, it was possible to divide the content into four topics: access to medicines for the treatment of neoplasms; access to high-complexity assistance units and high-complexity assistance centers in oncology; coverage of health plans and interventions for neoplasms; and exemption from income tax and social security contributions for people with cancer. Conclusion: as much as one may debate the prejudice of judicialization in the public policy cycle, the specifics of some neoplasms make judicialization more than necessary and effective because lives may depend on it.

Advent growth in information and communication technologies has accelerated the needs to secure digital media. Demands for digital media when on the move urged Quran readers to install the Quran mobile apps on their device. However, there is no secure mechanism to legalize its content credential. On the other hand, mobile developer finds difficulty in getting access to readily authentic Quran database sources. Malaysia government has introduced Smart Quran mobile apps without any counterfeit protection. Correspondingly, the contents are vulnerable to hacking, falsification which consequently endangering Islamic institutional prestige. There is also a lack of credible authorization institutions to verify authenticity of the digital Quran that could possibly deviate the Muslim faith by reciting falsified content and meaning. To fill the void, this paper explores the utilization of an image watermarking to preserve the Quran digital image. The study presents new blind RGB image watermarking using Fibonacci Transform via Discrete Wavelet Transform (DWT) and manipulates the R component of the Al-Quran image. The second level of LL decomposition of the cover image will then be substituted by the Fibonacci-transformed watermarked version. DWT embedding is achieved through alpha blending technique. Final watermarked image is obtained once RGB conversion is performed. The efficiency of the method is assessed towards 10 samples. Verification is conducted via the extraction of the endorsed license image. The results demonstrate enhanced robustness and imperceptibility with average PSNR and SSIM of 92.13 dB and 0.99 respectively. Forgery cases of digital Quran applications are therefore tackled.

The research paper describes the technology of temporary bonding for carrying out technological operations with semiconductor wafers with a diameter of 100 mm or less on equipment for a wafer diameter of 150 mm. The main technological processes for manufacturing a silicon substrate 300 μm thick with blind microholes (vertical grooves) 100 μm in diameter using temporary bonding technology are presented. Investigations of the elemental analysis of the formed structure of metals in blind microholes were carried out on the basis of spectral ellipsometry. Metallization was carried out by a combination of methods of atomic layer and magnetron sputtering, chemical and electrochemical deposition. The effect of expansion of the groove walls during deep plasma-chemical etching of silicon is shown. The developed technology of temporary bonding is intended for the production of silicon interposers with TSV holes, 2.5D and 3D microassemblies.

Published: December 2022

Synthesis of ZnO powders created by the sol-gel method for the use in the production of varistors is currently one of the promising areas. This method allows mixing of additives at the atomic level, which promotes a homogeneous distribution of impurities, it also makes it possible to control the particle size, which contributes to the miniaturization of the varistor and does not require secondary heating, and is also an environmentally friendly method. In this work, we carry out the synthesis of ZnO varistor powder with further fabrication of the varistor structure within the framework of the sol-gel method, as well as the study of the obtained samples at all stages of work. During the synthesis process, the ZnO powder was obtained by the sol-gel method, from which samples of varistor structures were made, at a sintering temperature of 900 °C. During the synthesis, the sol was studied at all stages of maturation by IR-Fourier spectroscopy; during the study, the formation of nano-aggregates in the gel and the presence of ZnO in the resulting powder were obtained. The structure of the instrumental samples was studied by scanning electron microscopy, during which the average grain size of ZnO was calculated as 0.25μm. The constructed volt-ampere characteristics in the voltage range of —220...220 Vhad a distinct non-linearity with a coefficient of 2.36.
The Diversity of Actors in Reform Backsliding and Its Containment in the Ukrainian Hybrid Regime
Authors: Richter Michael Martin
Published: December 2022

Numerous studies on democratic backsliding mostly focus on the state executive as a driving force. In contrast, the analysis presented here highlights the role of vested interests as the main actors behind backsliding processes in hybrid regimes. In a focused case study of anti‐corruption reforms in Ukraine, this contribution analyses the initiation of backsliding by these actors through their influence on nominally independent branches of power as well as the subtle takeover of the legislative repair process that followed. The case study is based on original semi‐structured expert interviews and document analysis. The main argument is that the distinct role played by the state executive also substantially changes the interaction between the actors involved. For the case of Ukraine, the study shows that the leverage of Western organisations in conjunction with the expertise and swift reaction of Ukrainian civil society organisations constitute a necessary precondition for the containment of backsliding attempts.
ARCHITECTONICS OF ‘AUSTERLITZ’, A NOVEL BY W. G. SEBALD
Authors:   Taras Shevchenko National University of Kyiv, Megela Ivan
Published: December 2022

The article describes the problems of architectonics as the main construction principle of Austerlitz, a novel by German author W. G. Sebald. The aim of this article is to analyze architectonics as a general system of connections between separate parts of the artistic whole, as well as an artistic discourse that organizes the interaction between the aesthetic subject, aesthetic object and aesthetic addressee through cohesion and coherence of elements of different levels of the text. The article describes the essence of the concept of time in the novel; each moment can be revisited both at the level of reminiscence and inner feeling. The concept of time is subordinate to the character’s pursuit – unraveling the mystery of his real ancestry and the way of exploring personal history in forgotten locations, cities and streets of lost time, in a phantom happy childhood. The article examines the formation of artistic space from the character’s past, his travels down the memory lane; from flashbacks, dialogues between Jacques Austerlitz and the nameless listener (narrator, in fact, the author of the work); from descriptions of architectural structures, penitentiaries, fortresses, castles; from black-and-white photographs of various objects, objects that give the text the authenticity of a chronicle. Austerlitz rejects the documentary – fiction dichotomy cannot be unambiguously defined either as fiction or as a historical work. The article argues that this is the literature of personal experience ‘from the other side’, when the theme of memory and destruction reveals itself not through established historical symbols, but through personal dialogue between man and the material world. The article argues that this is the literature of personal experience ‘from the other side’, when the theme of memory and destruction reveals itself not through established historical symbols, but through personal dialogue between man and the material world. The analysis concluded that the architectonics in Austerlitz functions as series of consecutive moral problems associated with individual guilt about historical events. It is a dense intertextual postmodern documentary-fiction novel in which the author's experience is combined with emotions, personal empathy, synesthesia, which separates him from the official interpretation of history, coverage of painful problems of the past (Holocaust), trauma and oblivion.

Introduction Osteotomy is an important part of orthopaedic interventions and can result in an injury to the periosteum reducing regenerative capabilities of the bone. Material and methods A device for processing the femur was developed to allow osteotomy be produced from the medullary canal. An experimental study was conducted on femoral models in two comparison groups (20 models in each). Osteotomy of the femoral shaft was performed at a distance of 15 cm from the apex of the greater trochanter. Duration of bone intersection and magnitude of partial and complete defects of the simulated periosteum were evaluated. Results The average duration of osteotomy was 482.8 ± 15.4 s in the main group and 181.3 ± 16.1 s in the control group. The average overall length of injury to the simulated periosteum to the entire depth was 1.4 ± 3.0 mm in the main group being significantly less in the control measuring 13.6 ± 3.8 mm (Mann-Whitney U-test = 7.0, p = 0.00). The average total length of partial injury to the periosteum (1.4±2.6 mm) was significantly less in the main group than in controls (21.8 ± 5.8 mm, Mann-Whitney U-test = 0.0, p = 0.00). Discussion The surgical device offered, as opposed to existing devices, allowed bone intersection to be performed with high accuracy. The presence of endoscopic control of the osteotomy depth ensured preservation of the periosteum. The device could be used for several bone cuts using a single surgical approach. Conclusion The use of the device slightly increased duration of the osteotomy and facilitated minimally invasive intervention retaining periosteum at the osteotomy site and provided better conditions for bone regeneration.

Introduction Annual microbiological monitoring of the leading causative agents of osteomyelitis and their antibiotic sensitivity is essential for identifying drugs that have lost the effectiveness. An increase in microbial associations requires different approaches to antibiotic therapy. Analysis of the composition of associations with a priority pathogen to be identified to avoid administration of ineffective drugs and optimize treatment. The purpose was to monitor qualitative and quantitative community composition of microorganisms isolated from the osteomyelitic focus in patients with chronic osteomyelitis over a three-year period. Material and methods The object of the study were strains of gram-negative and gram-positive bacteria isolated during primary inoculation as part of associations of bacteria from wounds and fistulas of patients who were treated in the clinic of infection osteology at the Kurgan Ilizarov Centre between 2018 and 2020. Standard bacteriological methods were used to isolate pure cultures. Bacteria were identified using bacteriological analyzer. Results and discussion Two-component microbial associations isolated in patients with chronic osteomyelitis included P. aeruginosa + S. aureus, Enterobacteriacae + S. aureus, S. aureus + CoNS. The strains of S. aureus and P. aeruginosa were most common pathogens identified in mixed cultures. Inoculations of S. aureus + Enterococcus sp. increased and P. aeruginosa + Enterococcus sp. associations showed a two-fold decrease in 2020 compared to 2018. Three- and four-component associations of bacteria increased with the spectrum of combinations being diverse among the isolated mix cultures over a three-year period. Bacteria of the Enterobacteriacae and S. aureus family were most common in three-component associations. Four-component associations were represented by mix cultures of gram-positive and gram-negative bacteria including NFGOB and S. aureus. Conclusion An increased frequency of isolated microbial associations necessitates an annual analysis of changes in the qualitative and quantitative composition to identify the spectrum of the most common microflora of the osteomyelitic focus and correct antibiotic therapy.

Introduction Telescopic intramedullary osteosynthesis (TIO) is used in children with osteogenesis imperfecta and other diseases accompanied by frequent fractures and deformities of long bones due to pathological bone tissue featuring reduced strength properties. Purpose In an animal experiment to study the growth characteristics of an intact tibia under conditions of intramedullary reinforcement with a telescopic rod. Material and methods A non‑randomized controlled study was conducted on 4 animals (puppies, littermates) that underwent TIO of the right limb tibia with a telescopic titanium rod (outer diameter of 4.2 mm) at the age of 5 months. X-ray parameters (length of the tibia, angles of inclination of the articular surfaces, telescoping magnitude) were studied before surgery, on the day of rod placement, and after the end of spontaneous growth of the segment (7 months after surgery). The contralateral left tibia served as a control, and its X-ray parameters were studied at the same time-points. Results Transphyseal reinforcement with a telescopic rod caused growth retardation with loss of length in only one case out of four (8 mm or 4.8 % of residual growth). In other cases, no difference in the length of the tibias of the right and left lower extremities was found. Eccentric insertion of the transphyseal rods into the posterior third of the distal epiphysis (due to the natural anatomy of the canine tibial shaft) formed an angular deformity during growth: a significant increase in the distal anterior and lateral tibial angles of the operated limb compared to the intact limb. The amount of divergenceof the parts of the rods was, on average, 11.3 mm. There were no cases of migration of intramedullary rods or loss of fixation of threaded sections in the epiphyses. Conclusion Under experimental conditions, the slowing down of longitudinal bone growth is not a constantly observed effect. Titanium telescopic rods are not prone to blocking during the limb growth or to losing the position of the threaded parts in the epiphyses. The eccentric passage of the rods through the growth zones causes angular deformities in the course of growth of the segment.

Introduction Osgood-Schlatter disease is manifested by pain, swelling and the appearance of a painful "bump" in the area of the tibial tuberosity. For 90 % of patients, conservative treatment is effective. It relieves painful symptoms but if they persist after the closure of the growth plate, surgical treatment is recommended. The study of literature reviews on invasive methods of treatment of the Osgood-Schlatter disease revealed only a few works on various methods of treatment with a description of clinical cases. Purpose Review of current methods of invasive treatment of Osgood-Schlatter disease, comparison of their effectiveness from the point of current evidence-based requirements. Materials and methods The electronic databases eLibrary, PubMed and Scopus were used for literature search. Results This literature review presents a comparative analysis of the effectiveness of various surgical methods of treatment, namely, the use of surgical and puncture methods. The main advantages of the methods were discussed, as well as their disadvantages caused by postoperative complications or difficulties resulting from the techniques for their implementation. Conservative treatment, which is resorted to in the majority of cases, does not relieve pain in the knee joint, and discomfort at sport activities persists. Minimally invasive techniques, which were used by a number of authors whose works are described in this review, are at a low level in the hierarchy of evidence, because there no large comparative studies. Conclusions Due to the rarity of surgical treatment of this pathology, it makes sense to create a register of patients with Osgood-Schlatter disease for the purpose of a remote unified assessment of treatment results in order to identify the most appropriate method of surgical intervention.
El centrismo y los partidos gubernamentales durante las transiciones democráticas en Grecia y España (1974-1982). La UCD y la ND: del Gobierno a la oposición
Authors: Balios Sethelos Isidoros
Published: December 2022

Los miembros de los Gobiernos que llevaron a cabo los procesos de la transición democrática en Grecia y España provenían de los sistemas políticos que las democratizaciones reemplazaron. Los ejemplos más destacados son los presidentes del Gobierno Adolfo Suárez y Constantino Karamanlís. El último, aunque no había colaborado con los coroneles, fue primer ministro durante el sistema de democracia «limitada» anterior de la dictadura. Durante las transiciones, los partidos que encabezaron, la UCD y la ND, se presentaron como partidos centristas o centroderechistas con un discurso más liberal que conservador. El objetivo era conquistar el voto moderado del centro, una estrategia que resultó correcta en las elecciones generales que fueron celebradas en estos países durante la segunda mitad de los setenta. El presente artículo tratará de un estudio comparado de estos dos partidos y Gobiernos desde los comienzos de las transiciones y hasta el fin de su hegemonía política en 1981-‍1982. Además, el estudio examinará el discurso político de los dos partidos, su influencia electoral, así como los cambios políticos y sociales en los dos países y su impacto en la estrategia de estos dos partidos.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the abdominal area. They can involve any portion of the gastrointestinal (GI) tract, omentum, mesentery, retroperitoneum, and other sites. They form 1-2% of the histologic types of gastrointestinal tract tumors. Aims and objectives were to analyze and correlate morphological, clinical and histomorphology features of gastrointestinal tumors presenting at different sites.Methods: This was a retrospective observational study for six years. Medical records of the histopathologically diagnosed GIST cases were reviewed for patient demographics and clinical presentation, and tumor findings were noted.Results: Of the 28 patients, ages ranged from 28 to 80 years. Symptoms ranged from abdominal pain, epigastric discomfort, mass, upper/lower gastrointestinal bleeding, rectal bleeding, anemia, weight loss, and small bowel obstruction. Sites involved were the small bowel, stomach, mesentery, rectum, duodenum, greater omentum, and retroperitoneum. Of 28 cases of GIST, 25 cases showed both c-KIT and DOG-1 positivity, 1 case showed only c-KIT positivity, 1 case showed only DOG-1 positivity, and 1 case was both c-KIT and DOG-1 negative.Conclusions: GISTS are unpredictable mesenchymal tumors. Common sites are the stomach and small gut. Mesenteric and omental GIST are rare. Spindle cell morphology was more commonly present.

Cervical oesophageal perforation is a potentially life-threatening situation associated with pooled mortality of 5.9%. Early detection and referral to the thoracic surgery is important. We present a case of an obese lady admitted for foreign body ingestion and had an endoscopic removal of foreign body. Her general condition deteriorated two days later and the diagnosis of delayed cervical oesophageal perforation was made. She was managed surgically by placement of T-tube as controlled-fistula, nasogastric tube insertion and drain at superior mediastinum to control sepsis and contamination. Patient was discharged well despite prolonged hospital stay. T-tube drainage is established as safe and effective to manage delayed cervical oesophageal perforation.
