Published: October 2024

El consumo de bebidas azucaradas entre estudiantes universitarios es un fenómeno que ha ganado atención en las últimas décadas, impulsado por un estilo de vida acelerado y la prevalencia de opciones alimenticias convenientes en entornos académicos. Las bebidas como refrescos, energizantes y jugos azucarados son parte de la dieta de muchos jóvenes, a menudo buscando una rápida fuente de energía para enfrentar largas jornadas de estudio y exigencias sociales. Pero este patrón de consumo conlleva implicaciones en la salud que van más allá de la mera ingesta de calorías. Los efectos de las bebidas azucaradas, como el aumento del riesgo de obesidad, diabetes tipo 2 y problemas dentales, son preocupaciones significativas en esta población. Además, el impacto en el rendimiento académico y el bienestar general comienza a recibir más atención. Explorar los hábitos de consumo de bebidas azucaradas entre los estudiantes universitarios es esencial para entender cómo estos patrones afectan su salud y su rendimiento académico, y para desarrollar estrategias efectivas que promuevan alternativas más saludables en este crucial periodo de sus vidas. El objetivo es analizar el consumo de bebidas azucaradas entre estudiantes de las carreras de Medicina y Enfermería de la Universidad de Guanajuato, así como su relación con indicadores de salud como los niveles de glucosa, circunferencia de la cintura y el IMC. Metodología: Estudio cuantitativo, no experimental de tipo transversal, correlacional y observacional. Los sujetos de estudio fueron 11 estudiantes de carreras de ciencias de la salud, a quienes se les midió circunferencia abdominal, glucosa, presión arterial, IMC y se les aplicó el Cuestionario de Ingesta de Bebidas (Beverage Intake Questionnaire: BEVQ). Los resultados obtenidos revelan una asociación significativa y positiva entre el consumo de estas bebidas y los niveles de glucosa, circunferencia de la cintura y el IMC, en un nivel bajo, lo que sugiere un riesgo importante para el desarrollo de enfermedades metabólicas. Se identificó que las calorías diarias consumidas en bebidas azucaradas supera lo recomendado.

El estudio de la estabilidad de fármacos como la claritromicina demuestra la importancia de establecer su período de vida útil y condiciones de almacenamiento. La claritromicina, un antibiótico macrólido, es eficaz contra diversas infecciones bacterianas y se metaboliza a un metabolito activo. Sin embargo, puede degradarse bajo ciertas condiciones, afectando su efectividad.
En este trabajo se propone un método de bajo costo, utilizando reacciones de hidrólisis para determinar el periodo de caducidad de una suspensión oral de claritromicina, utilizando espectrofotometría UV-Vis. Se prepararon diluciones y se midió la absorbancia a lo largo de 7 días. Los resultados mostraron que la concentración del principio activo disminuyó progresivamente, alcanzando un 90% de su efectividad en el séptimo día, confirmando la caducidad del medicamento.
Los objetivos del estudio incluyeron desarrollar una experiencia educativa para estudiantes sobre la estabilidad de medicamentos y difundir los resultados en eventos científicos. La metodología y los resultados destacaron la utilidad de la espectrofotometría como una alternativa eficaz para la determinación de fechas de caducidad de fármacos, asegurando su eficacia terapéutica. La investigación concluyó que este método es accesible y proporciona una forma confiable de evaluar la estabilidad de medicamentos.

Las zeolitas se caracterizan por ser materiales muy versátiles con aplicaciones en áreas tan diversas como catálisis, procesos de separación, adsorción, biotecnología y medicina. Uno de sus campos de investigación actual, es el desarrollar métodos de síntesis más amigables con el ambiente, que permitan mantener o mejorar las propiedades de los materiales mediante la combinación de metodologías de síntesis y el control de diversos parámetros. Es por ello, que en el presente trabajo se estudió el efecto de la técnica de sembrado asistida por sonicación sobre la obtención de zeolitas de tipo zincosilicato. Se evaluaron dos semillas zeolíticas: silicalita y zincosilicato, ambas de topología MFI. Las semillas se usaron en forma de cristal (sólido) y gel. La sonicación se realizó con una sonda a diferentes periodos de tiempo. Posteriormente, se llevó a cabo la cristalización mediante el método hidrotermal. Los productos obtenidos se caracterizaron mediante DRX. Se obtuvo la formación de un zincosilicato de topología VSV, indicando una transformación interzeolitica durante el proceso de cristalización. La composición química de la semilla influyó significativamente en la fase obtenida, la semilla silicalita (cristal) favoreció la obtención del zincosilicato VPI-7 como fase única, mientras la semilla de zincosilicato promovió la coexistencia de VPI-7 y zincita en el producto final. El tiempo de sonicación tuvo efecto sobre la cristalinidad y el rendimiento del material obtenido. Con base a lo anterior, se puede inferir que el método hidrotermal asistido por sonicación y sembrado puede ser aplicado en otro rango de composiciones que permitan obtener materiales zeoliticos de distinta topología.

En México, el análisis de tendencias electorales se basa principalmente en encuestas telefónicas dirigidas a ciudadanos con servicio de línea fija. A pesar de la validación comprobada de tales métodos, este enfoque de muestreo, además de ser económicamente y logísticamente pesado, no logra reflejar con precisión la realidad actual de la mayoría de los votantes, quienes son predominantemente usuarios activos de plataformas de redes sociales. Dada la amplia disponibilidad de vastos repositorios de datos de acceso gratuito y la aplicación de técnicas modernas de inteligencia artificial, surge la oportunidad de obtener percepciones significativas sobre las preferencias electorales que conducen a junio de 2024. Comparar estos hallazgos con los resultados finales del proceso electoral se erige como un medio para fortalecer la validez de los métodos alternativos empleados en dichos procesos.
Preserving Athletic Performance at Altitude with Heat Acclimation: A Cross-Adaptive Approach
Authors: Albert Beverly , Miller Michael G.
Published: October 2024

Decreased oxygen availability at high-altitudes, referred to as hypoxia, reduces physical capacity and places athletes at risk of illness. Accelerated warming in mountainous regions compounds the environmental burden of these settings. Cross-adaptation (CA) involves using 1 stressor (e.g., heat) to reduce the physiologic strain of another (e.g., altitude). CA has the potential to alleviate the adverse effects of unaccustomed environmental conditions on sports performance when other options are not feasible. Through repeated exposures, heat acclimation (HA) provides a valuable alternative for altitude preparation as global temperatures rise. Environmental stressors may occur alone or in combination, further supporting the use of HA to protect against life-threatening heat illness during simultaneous exposures. This review highlights the mechanisms of HA that support performance at altitude, synthesizes heat-hypoxia CA research, and provides practical recommendations for effective implementation.
Bandidaje Mexicano Frente a la Ley del Gabacho
Authors: Arce B. Christine
Published: October 2024

Este ensayo explora la importancia del canto popular del sureste de Texas como respuesta de la comunidad fronteriza a la violencia extralegal tanto de las autoridades como de las multitudes (mobs) anglotejanas. Tomando como objeto de análisis la muerte polémica del mexicano Juan García en 1931 en Eagle Pass, Texas, se compara la versión oficial del episodio narrada en el periódico local con la historia que cuenta “El corrido de Juan García,” balada poco conocida escrita en Piedras Negras, México. Este corrido representa su propio discurso subversivo, puesto que desafía la verdad oficial creada por las autoridades estadounidenses. Asimismo, “El corrido de Juan García” opera como fragmento histórico que no sólo ilumina los acontecimientos violentos de la comunidad fronteriza, sino que también constituye una memoria colectiva y una cosmovisión propia del corrido que rebasa los límites entre las clases letradas y populares en las zonas fronterizas. El episodio de Juan García permite apreciar cómo el mito del bandidaje mexicano ha infundido miedo tanto en el imaginario cultural como en el discurso político estadounidense. Infiltrado por imágenes de la delincuencia mexicana, este discurso permite—e incluso justifica—la persecución del mexicano, y ha penetrado, de forma diferente, el discurso en torno al inmigrante latinoamericano contemporáneo. La mitología teratológica y sin matiz del “bandido” que proyecta el género fílmico del Western ha renacido con la figura del “alienígena ilegal.”
“USA Is Trespassing in New Mexico”
Authors: Trujillo Simón Ventura
Published: October 2024

A formative organization of the Chicana/o movement in the 1960s and 1970s, La Alianza Federal is remembered for the Tierra Amarilla courthouse raid and for the political and religious activism of its president, Reies López Tijerina. Yet little attention has been given to the discourse of Indo-Hispano, La Alianza’s deployment of mestizaje that predates and diverges from the dominant icons and tropes of Chicana/o mestizaje. Drawing from archived primary sources, this essay reconsiders Indo-Hispano as a discourse of mestizaje produced at the intersection of Tijerina’s research in multiple archives of colonial law and the memories of ejido land grant tenure and loss provided by Alianza members. I situate Indo-Hispano discourse as a rearticulation of the mestiza/o pasts of genízaro Indians, detribalized Plains and Pueblo Indian captives who were resettled into land grants as a buffer to protect the Spanish colonial interior of New Mexico from Indian raids during the seventeenth and eighteenth centuries. By locating Indo-Hispano discourse in a history of tribal and colonial hybridity in the Americas, I rethink La Alianza as an experiment in collective history writing and highlight the indigenous, coalitional, and feminist operations of its textual output.
Agroecological education on contested ground: Brazil’s Landless Workers’ Movement and the politics of knowledge
Authors: Meek David , Fernandes Bernardo Mançano , Coca Estevan
Published: October 2024

This article focuses on the contested interconnections between affective labor, agroecological education, and territory in the state of Minas Gerais, Brazil. We understand territory to be both embodied, material and immaterial: whereas material territory signifies the physical morphology of landscapes, immaterial territory surrounds the landscape of ideas; both forms of territory are experienced and structured by affective labor. Drawing upon insights from the political ecologies of education and emotion as well as Brazilian agrarian geography, we explore how the politics of knowledge structure affective labor, and reciprocal contestations over material and immaterial territory. This article focuses on one of the most highly publicized and contested agrarian spaces in contemporary Brazil: the Quilombo Campo Grande community. Quilombo Campo Grande is a social movement territory organized and occupied by Brazil’s Landless Workers’ Movement (MST), the largest agrarian reform movement in Latin America. This community has existed since 1996, and is comprised of 11 encampments. Until 2020, Quilombo Campo Grande contained a federally recognized school, known as the Escola Estadual Eduardo Galeano. As part of an August 2020 federally mandated eviction order, the communities’ school was destroyed by the state. Following extensive grassroots social mobilization, both domestically and internationally, the school was rebuilt, but transformed from a state school to a movement space, now known as the Regional Center for Agroecology. We analyze interviews with members of the MST’s state and national education sectors, and educators within the Regional Center for Agroecology. Our results highlight how material and immaterial resources are mobilized to structure affective labor. They also underscore the ongoing and evolving conflict between material and immaterial territory, emphasizing that in Brazil agrarian reform and agroecological knowledge are in direct physical and ideological conflict with the territorial vision of agribusiness.

Authors: Droppelmann Guillermo , Rodríguez Constanza , Smague Dali , Jorquera Carlos , Feijoo Felipe
Published: October 2024

Purpose

Different deep-learning models have been employed to aid in the diagnosis of musculoskeletal pathologies. The diagnosis of tendon pathologies could particularly benefit from applying these technologies. The objective of this study is to assess the performance of deep learning models in diagnosing tendon pathologies using various imaging modalities.

Methods

A meta-analysis was conducted, with searches performed on MEDLINE/PubMed, SCOPUS, Cochrane Library, Lilacs, and SciELO. The QUADAS-2 tool was employed to assess the quality of the studies. Diagnostic measures, such as sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood ratios, area under the curve, and summary receiver operating characteristic, were included using a random-effects model. Heterogeneity and subgroup analyses were also conducted. All statistical analyses and plots were generated using the R software package. The PROSPERO ID is CRD42024506491.

Results

Eleven deep-learning models from six articles were analyzed. In the random effects models, the sensitivity and specificity of the algorithms for detecting tendon conditions were 0.910 (95% CI: 0.865; 0.940) and 0.954 (0.909; 0.977). The PLR, NLR, lnDOR, and AUC estimates were found to be 37.075 (95%CI: 4.654; 69.496), 0.114 (95%CI: 0.056; 0.171), 5.160 (95% CI: 4.070; 6.250) with a (P < 0.001), and 96%, respectively.

Conclusion

The deep-learning algorithms demonstrated a high level of accuracy level in detecting tendon anomalies. The overall robust performance suggests their potential application as a valuable complementary tool in diagnosing medical images.

Las Compras Verdes En Los Suministros Básicos Del Estado Peruano, Hacia Un Liderazgo Con El Ejemplo
Authors: Viacava Paredes Gloria María
Published: October 2024

Perú ha estado implicado activamente en responsabilidades ambientales desde hace tiempo, junto con algunas organizaciones como la OCDE y como miembro de las Naciones Unidas está comprometido a continuar actividades que propugnen la temática del desarrollo sostenible y el desarrollo por la sostenibilidad mundial, dirigiendo algunos aportes enmarcados en fondos y programas para lograr una verdadera comisión ambiental frente al cambio climático, en pro a la demanda de las empresas en la prevalencia de objetivos sociales y ambientales. Sin embargo, estos acuerdos no se cristalizan en políticas públicas concretas, siendo limitados los criterios ambientales en las compras estatales. En el Perú, el 56,7% de las compras estatales corresponden a la compra de bienes y servicios, mientras que el 43% son para métodos de producción, opciones de reciclaje y reutilización de insumos.

Gender Impacts of COVID-19 on the Labor Market and Household Wellbeing in Pakistan
Authors: Tas Emcet O. , Ahmed Tanima , Matsuda Norihiko , Nomura Shinsaku
Published: October 2024

This study examines the gender impacts of the COVID-19 pandemic on the labor market and household wellbeing, using an online survey of the users of Pakistan’s largest online job platform. The analysis shows that the pandemic led to an unprecedented level of economic insecurity for employees and employers alike, resulting in widespread job loss, business closures, a slowdown in business activity, and reduced working hours. The sectors where female workers are heavily concentrated, such as education, were more severely affected. The pandemic has also led to a disproportionate increase in women’s unpaid care work and increased their reported rates of stress and anxiety. These findings suggest that the pandemic had significant wellbeing impacts on women in Pakistan, including a decline in the female labor force participation rate, which is already among the world’s lowest.
The Welfare State and Economic Growth – Econometric Evidence from Germany
Authors: Reichel Richard
Published: October 2024

This paper attempts to analyze the growth effects of social security expenditures in Germany from a time series perspective. Therefore, a regression model based on standard determinants of growth is specified and estimated as a vector error correction model. Results show that there is a bidirectional relationship between growth and social security expenditures. In the short run, social security expenditures and growth rates are inversely related. Lower or even negative growth rates cause higher expenditures of the welfare state. In the long run, there is also an inverse relationship, but the direction of causality changes. Higher social security spending triggers lower growth rates. Robustness tests confirm the stability of the results.
Energy Input Interaction in US Output
Authors: Copeland Cassandra , Thompson Henry
Published: October 2024

This paper estimates production functions for annual US output from 1949 to 2013 adding energy Btu input to fixed capital assets and the labor force.  Interactions between inputs are parsimoniously introduced in the error correction estimates.  Fixed capital assets successfully imbed technology.  Energy and capital are weak substitutes or complements due to their positive interaction.  Energy is substantially underpaid relative to its increasing productivity while labor is increasingly overpaid relative to its declining productivity.  Factor price elasticities involving labor and the wage are noticeably strong.  The nearly elastic own wage effect explains the challenges facing labor.
COVID-19 effects on the Canadian term structure of interest rates
Authors: Severino Federico , Cremona Marzia A. , Dadié Éric
Published: October 2024

In Canada, COVID-19 pandemic triggered exceptional monetary policy interventions by the central bank, which in March 2020 made multiple unscheduled cuts to its target rate. In this paper we assess the extent to which Bank of Canada interventions affected the determinants of the yield curve. In particular, we apply Functional Principal Component Analysis to the term structure of interest rates. We find that, during the pandemic, the long-run dependence of level and slope components of the yield curve is unchanged with respect to previous months, although the shape of the mean yield curve completely changed after target rate cuts. Bank of Canada was effective in lowering the whole yield curve and correcting the inverted hump of previous months, but it was not able to reduce the exposure to already existing long-run risks.
Human Capital and Regional Growth in Switzerland
Authors: Polasek Wolfgang , Schwarzbauer Wolfgang , Sellner Richard
Published: October 2024

This paper develops a regional production function model for Swiss cantons that incorporates human capital together with spatial effects. Within a spatial panel framework we find that controlling for time effects the spatial spillover effect becomes insignificant. Our results are sensitive with respect to the human capital proxy. We find that the share of academics in the workforce is the main component of human capital driving productivity growth in Swiss cantons. This is in line with findings of previous studies suggesting that mostly highly skilled workers matter for productivity growth in technologically advanced economies.

The radiation protection of the public against ionizing radiation emitted by natural sources from the earth's crust is a public health issue. The aim of this study, carried out in the granite quarries and schools of the towns of Glazoue and Dassa-zoume, is to assess the population's external exposure to ambient gamma radiation emitted by natural radionuclides (238U, 232Th, 40K, etc.). It covered the dry season from January to April 2021. 12 quarries and 39 schools were included in the study. 510 ambient gamma dose equivalent rates were carried out during the study period with the radiometer and the portable NaI gamma detector simultaneously. For comparison purposes, ten (10) measurements were taken in the city of Cotonou. Gamma dose equivalent rates in the quarries of both cities ranged from 0.11 to 0.40 µSv/h, with an average of 0.255 µSv/h. Those for primary and secondary schools vary from 0.08 to 0.40 µSv/h, with an average of 0.24 µSv/h. The average dose equivalent rate recorded at Cotonou is is 0.045 µSv/h. The effective dose for a resident crusher ranges from 1.10 to 2.80 mSv/yr, with an average of 2.10 mSv/yr. Those for non-resident crushers range from 0.6 to 1.4 mSv/yr. Those for schools range from 0.144 mSv/yr to 0.432 mSv/yr, with an average of 0.252 mSv/yr. The effective dose obtained for granite crushers is higher than the value mentioned in the 2008 UNSCEAR report for outdoors and indoors exposure to terrestrial and cosmic radiation, which is equal to 0.87 mSv/yr.
Prolonged lower limb dystonia and dysphonia following general anaesthesia in a patient on Hydroxyzine
Authors: Wijerathne Tharaka
Published: October 2024

A female patient in her early 40s presented with prolonged lower limb dystonia following general anaesthesia in multiple occasions. She once developed transient aphasia and prolonged dysphonia after total intravenous anaesthesia. She had uneventful anaesthetics before the prescription of hydroxyzine for her skin condition. All post anaesthetic dystonic events were reported while she was on hydroxyzine. Spasmodic laryngeal dystonia can result in dysphonia. The possible mechanisms of dystonia can be explained using a compartmental model of the striatum. An imbalance between cholinergic and dopaminergic systems in basal ganglia results in dystonic reactions. Changes in the endocannabinoid system could partly explain the effects on movement disorders after propofol administration. Antagonistic effect of hydroxyzine on dopamine 2 receptors in the striatum can result in predominant excitatory motor effects and movement disorders. Detailed history of the patient and analysis of findings with the clinical knowledge is important for the management of rare perioperative presentations of movement disorders.

Psicanálise e Teologia
Authors: Armand Dentz Junior René , Lima e Santos Gustavo
Published: October 2024

A partir da pós-modernidade, vivenciamos uma dissolução de absolutos. A atitude hermenêutica ganha espaço ao possibilitar transitar no conhecimento sem fundamentos rígidos. Trata-se de uma proposta que atesta a finitude humana e sua condição de temporalidade. Diversas áreas do saber buscaram entender como poderiam superar absolutos intrínsecos ou residuais e encontrar um caminho de interpretação a partir de um horizonte específico de compreensão. A Psicanálise e a Teologia foram áreas que lidaram com os impactos de uma “virada hermenêutica”. No entanto, ainda permanecem muitos elementos e “tentações absolutas”. Como poderíamos compreender os campos psicanalítico e teológico enquanto interpretativos? Como superar os fundamentos absolutos e a metafísica? Nossa condição faltante nos indica possibilidades interpretativas que atestam a própria vulnerabilidade da incompletude.
A pandemia de Covid 19
Authors: Grümme Bernhard
Published: October 2024

A pandemia corona seria uma oportunidade e um teste para a educação religiosa? Seria o espaço para questões existenciais? Pode ser que a educação religiosa, na sua orientação normativa para a liberdade através de uma agenda oculta nas suas estruturas e práticas profundas, se torne menos uma escola de linguagem de liberdade do que uma escola de particularidade ou mesmo de falta de liberdade. Para mostrar a relevância deste sistema crítico-produtivo, procede-se, através de uma abordagem teórico-bibliográfica, em três passos: primeiro, uma abordagem exemplar através do discurso da vulnerabilidade; segundo, demonstrar as suas aporias; finalmente, contorna-se a dimensão política da educação religiosa como um elemento essencial, em sua relevância enquanto sistema crítico-produtivo.

Uma coisa só? Provocações sobre hibridização de rádio, TV e internet sob a convergência
Authors: Ferraretto Luiz Artur
Published: October 2024

Descreve a hibridização, um processo construído na esteira do rádio hipermidiático (Lopez, 2010), do rádio expandido (Kischinhevsky, 2016) e da PluriTV (Brittos; Simões, 2011), caracterizado pela transmissão de conteúdos simultaneamente por rádio, televisão e internet. Parte das ideias de cultura da convergência (Jenkins, 2008), cultura da conexão (Jenkins; Ford; Green, 2014), remediação (Bolter; Grusin, 1999) e midiamorfose (Fidler, 1998). Assim, dentro da fase de convergência (Ferraretto, 2012), constata-se, alterando o rádio como instituição social e criação cultural (Meditsch, 2010), pontos de tensionamento entre: a) a concorrência dentro do meio (Ferraretto; Morgado, 2018) e a disputa generalizada pela atenção do público (Davenport; Beck, 2001); b) a sociedade individualista de massa (Wolton, 2004) e a necessidade de pertencimento (Baumeister; Leary, 1995); c) o consumo massivo em tempo real e o consumo diferido ou por demanda, em um contexto de economia da cauda longa (Anderson, 2008); e d) a recepção do conteúdo em si e o reprocessamento do transmitido com base no mashup (Chandler; Munday, 2011).

Effect of cold and frozen storage on veined rapa whelk (Rapana venosa) meat quality
Authors: Zhelyazkov G. , Stratev D. , Strateva M.
Published: October 2024

Abstract. The study aim was to determine the impact of storage period on veined rapa whelk (Rapana venosa) meat, either chilled for 6 days or frozen for 3, 6, 9 and 12 months on its technological traits, chemical composition and fatty acid profile. Rapa whelks were collected by divers in June 2021 from the Black Sea, one nautical mile off the Bulgarian coast. A total of 60 kg of rapa whelks were collected from a depth of 10-15 m. The water holding capacity, cooking and roasting losses, meat proximate composition and fatty acid profile were analysed in the laboratories of the Faculty of Agriculture, Trakia University. Statistically significantly (P<0.05) lower water holding capacity of veined rapa whelk meat was observed after being stored chilled at 0-4°C for 6 days, or frozen at -18°C for 3, 6, 9 and 12 months compared to fresh meat. Cooking and roasting losses of meat did not change after 6 days of cold storage as well as after 3, 6 and 9 months of frozen storage, but worsened significantly after 12 months of storage at -18°C, which should be taken into account during storage and technological treatments of rapa whelks. The moisture, protein, lipid, ash and fatty acids content of rapa whelk meat remained unchanged during chilled and frozen storage. PUFA/SFA ratios indicated that fresh, cold-stored for 6 days and frozen for 3, 6, 9 and 12 months rapa whelks were an excellent source of PUFA and n-3 for humans.
Impact of the Thoroughbred horse breed on the development of the Bulgarian sport horse breed
Authors: Vlaeva R.
Published: October 2024

Abstract. The Bulgarian sport horse (BSH) is a newly recognized breed selected entirely for equestrian sports (show jumping, dressage, and eventing). Thoroughbred stallions were widely used in the breeding process during the first stage of the development of the new breed. As in many other half-blooded horse breeds, the Thoroughbred horse is a well-recognized breed used in the process of development to improve stamina and movements. The aim of this study was to analyze the genealogical structure of the BSH and to trace the sire lines of Thoroughbred stallions as well as the family (mare) lines descending from the mares of the Thoroughbred breed. The research covers the period 1970–2018 and includes all horses enrolled in the three completed volumes of the Studbook of the breed. The information was provided by the “Bulgarian Sport Horse Association. As a result, four sire lines were determined, including 51 stallions, and three families were established representing 26 mares. The population of the newly approved horse breed (BSH) has a well-developed genealogical structure owing to the consistent and correctly conducted selection process during the nearly 60-year period of its creation. Despite the great interest of breeders and athletes involved in equestrian sports to use more and more stallions from the famous European riding breeds as sires, the Thoroughbred breed should be included in the breeding process through the method of “blood-infusion”.

Abstract. The longstanding animal husbandry practices in small ruminants have led to the prevalence of various diseases, particularly parasitic infections. Among these, gastrointestinal helminthoses are widespread globally, exhibiting high prevalence and incidence rates, which contribute to significant morbidity and moderate mortality. The adverse pathogenic effects of parasites on the host organism result in clinically evident diseases and increased mortality, especially among younger animals, and also entail negative economic consequences. These consequences include reduced wool and milk production, poorer young animal rearing, and decreased overall body resistance, making animals more susceptible to other diseases. Our study focused on identifying optimal measures for controlling infections in small ruminants within the Mariovo District in the Pelagonia Region. We emphasized the crucial need for implementing these measures to protect small ruminant health and ensure production success. Integrating parasite control strategies, including systematic monitoring of infection rates, is essential for achieving these goals. These measures included determining optimal time of parasitological control of herds of small ruminants; optimal time of deworming; inspection of pastures before and during the grazing season; optimization of the way of use and eradication of pastures, monitoring of the achieved results. Conducted over the period of 2014-2022, this research yielded consistent results, highlighting the importance of combating parasitic diseases in this region.

The dominant lactic acid bacteria (LAB) population in traditional Muş Tulum cheese, which is produced from unpasteurized sheep’s milk, was identified during the ripening period (on the 1st, 45th, and 90th day) using biochemical, phenotypic, and genotypic techniques. Additionally, the isolated LAB strains were assessed for their technological characteristics. Enterococcus spp. accounted for 76.92 % of the sequenced isolates, while Lactiplantibacillus spp., Lactococcus spp., and Pediococcus spp. represented 15.38 %, 6.15 %, and 1.54 % respectively. All Lactococcus strains as well as E. faecium FFH2 and Lb. plantarum FFH59 strains showed high acidification capacity. E. faecalis (FFH46 and FFH14), L. lactis subsp. lactis FFH51 and E. faecium FFH16 strains showed high proteolytic activity (2.0593-2.2452 FFA mmol/L). Two Enterococcus strains (E. faecium FFH12 and E. faecium FFH77) with potential bacteriocin production and antimicrobial activity were identified. The results indicated that Enterococcus spp. was the dominant flora throughout the ripening period of Muş Tulum cheese, followed by Lactiplantibacillus spp.

The development of composite materials and products with a complex internal structure poses questions to develop experimental methods to determine the stress-strain state. Standard experimental methods do not provide a broad picture of the internal changes in the inhomogeneous samples under loading. Moreover, a presence of internal defects, porosity, local buckling can significantly effect on the obtained results. Despite the development of tomography and data processing methods most studies are performed without any external loading on sample. The research presents a methods for studying the porosity of samples under uniaxial compression using an X-ray computed tomography. For this purpose, special equipment that allows loading the sample inside the tomography was made. Additionally, a methodology was developed. The equipment allows not only to transfer the axial compression force, but also to measure the corresponding load value. The equipment was designed to reduce artifactual rays in a place where studied sample mounted. To determine the reference points under loading, a contrasting copper grid was used. A modified Harris detector was used to quantify the displacements. The displacements of the reference points were interpolated to a regular initial grid to estimate the displacements inside the sample. Test samples were designed and manufactured using additive technologies to illustrate the methodology. A series of loadings and tomography scans were carried out for each sample. The tomography data were processed according to the methodology. As a result, the displacement fields of the samples, the values of porosity, volumetric strain and their distribution over the sample for each loading step were obtained.

Forging processes are traditional methods of metalworking, their application is very extensive and allows the manufacture of metal products for various industries in a wide temperature range. The redistribution of the main acting forces during forming is a necessary condition for the transfer of traditional forging methods to high-tech methods of metal production. The main products of press-forging production are forgings such as pallets and plates. In the present work, the effect of shear forces on the stress-strain state is studied when the friction forces are redistributed on the contact surface and/or the nature of the metal flow changes during upsetting of wide strips. The analysis of the stress state was carried out by the method of slip lines compared with the existing method of settlement without shear. The field of slip lines and the hodograph of velocities for the draft of the strip with a shift are compiled. The stresses and intensity of the shear deformation were estimated by the analytical method. It was revealed that the upsetting of the strip between plane-parallel plates is accompanied by extremely uneven deformation over the section of the workpiece. The stress state is compared with traditional deformation and with superimposed shear deformation. The use of shears made it possible to realize predominantly compressive stresses, which make it possible to eliminate internal defects of the workpiece of foundry origin. The introduction of shear deformations contributes to the intensification of the plastic deformation process over the entire cross section of the strip, the stress values during draft with additional shear increase on average 4-6 times compared to normal draft. The increase in stress occurs due to the development of the intensity of shear deformation, reaching a value of 0.4 per compression.

The object of study. The upper upward position of the pendulum subjected to vibration of the pendulum base is known to be stable for some parameters of the base vibration. The research is devoted to dynamics of the model of a two-link inverted pendulum in a general nonlinear formulation. The goal. The boundaries of the parameters of a given base vibration, under which the inverted mode is stable, are assumed to be known. The goal is to find the regions of the initial conditions of the problem, namely, the initial non-small angles of deviation of the pendulum links from the vertical that result in stable oscillation in the inverted position. We intend to reveal the impact of the rod compressibility on the oscillation mode, as well as the influence of the resonance on stability in the framework of more complex formulation of the problem which involves account for small elastic axial deformation in the rods. Methods. By applying the laws of dynamics to the moving elements of the structure, we derive the complete nonlinear system of equations of the pendulum motion in two formulations: (i) for a system with two and (ii) four degrees of freedom, respectively. The equations include the parameter of small base vibration amplitude, which makes it possible to apply the two-scale asymptotic expansion method. The method leads to a system of averaged equations of motion which is convenient for the benchmark study of parameters. Results. The modes and eigenfrequencies of small oscillations of the pendulum are found depending on the dimensionless parameter of the problem. In the nonlinear for-mulation, the maximum deviations of the pendulum links are calculated which ensure a stable solution to the problem for zero initial angular velocities. Depending on the initial phase of vibration of the base, the boundaries of absolute and partial zones of stability of vibrations are obtained. In the absolute zone, stable oscillations are realized for any value of the initial phase of the base vibration. In the partial region, stable oscillation occurs at least for one set of initial condition. The dynamics of the pendulum is compared with and without account for rod the compressibility. The results are presented in the graphs.
