BACKGROUND: The biological properties of silicone elastomers such as polydimethylsiloxane (PDMS) have widespread use in biomedicine for soft tissue implants, contact lenses, soft robots, and many other small medical devices, due to its exceptional biocompatibility. Additive manufacturing of soft materials still has significant challenges even with major advancements that have occurred in development of these technologies for customized medical devices and tissue engineering. OBJECTIVE: The aim of this study was to develop a mathematical model of tangential stress in relation to shear stress, shear rate, 3D printing pressure and velocity, for non-Newtonian gels and fluids that are used as materials for 3D printing. METHOD: This study used FENE (finitely extensible nonlinear elastic model) model, for non-Newtonian gels and fluids to define the dependences between tangential stress, velocity, and pressure, considering viscosity, shear stress and shear rates as governing factors in soft materials friction and adhesion. Experimental samples were fabricated as showcases, by SLA and FDM 3D printing technologies: elastic polymer samples with properties resembling elastic properties of PDMS and thermoplastic polyurethane (TPU) samples. Experimental 3D printing parameters were used in the developed analytical solution to analyse the relationships between governing influential factors (tangential stress, printing pressure, printing speed, shear rate and friction coefficient). Maple software was used for numerical modelling. RESULTS: Analytical model applied on a printed elastic polymer, at low shear rates, exhibited numerical values of tangential stress of 0.208–0.216 N m - 2 at printing velocities of 0.9 to 1.2 mm s - 1, while the coefficient of friction was as low as 0.09–0.16. These values were in accordance with experimental data in literature. Printing pressure did not significantly influence tangential stress, whereas it was slightly influenced by shear rate changes. Friction coefficient linearly increased with tangential stress. CONCLUSION: Simple analytical model of friction for elastic polymer in SLA 3D printing showed good correspondence with experimental literature data for low shear rates, thus indicating possibility to use it for prediction of printing parameters towards desired dimensional accuracy of printed objects. Further development of this analytical model should enable other shear rate regimes, as well as additional soft materials and printing parameters.

Analysis of phase equilibria in liquid chromomanganese steel in the presence of calcium. Report 2. Phase equilibria in the system Fe–Ca–Cr–Mn–C–O (economy-alloy steels).
Authors: Makrovets A. L. , Bakin I. V.
Published: June 2024

Recently, materials devoted to the behavior of active elements in liquid steel during its out-of-furnace processing have been actively published. The processes of formation of nonmetallic inclusions during the interaction of oxygen with deoxidizers and modifiers (Al, Si, Ca, Ba, etc.) in iron-carbon melts have been studied in sufficient detail. Moreover, in a real metal, the process of deoxidation and modification takes place in the presence of alloying elements, which can noticeably change the composition of the forming phases. To assess the influence of the main alloying elements on the formation of non-metallic inclusions, it seems advisable to carry out work on thermodynamic modeling of the processes taking place in liquid steel in the presence of chromium and manganese. In this work, emphasis is placed on economically alloyed steel grades containing up to 2 (wt.) % of manganese, up to 1.5 (wt.) % chromium and up to 1 (wt.) % carbon. The influence of the content of main alloying elements on the deoxidizing ability of calcium in liquid steel has been studied. Liquid oxide inclusions can form when the chromium content at the level of tenths of a percent, manganese at the level of 0.1 (wt.) % and calcium less than 10–4 (wt.) % (1 ppm). The appearance of calcium chromite as non-metallic inclusions is possible in a narrow range of liquid metal compositions. In the presence of carbon, the formation of an oxide melt as an equilibrium non-metallic phase becomes impossible. At a low calcium content, the formation of calcium chromite and chromium oxides as non-metallic inclusions is most likely, and the residual oxygen content in the liquid metal will be about 0.04 (wt.) % (400 ppm).

[Case Study] Genetic and Clinical Insights into Congenital Leukemia in a Newborn Conceived via IVF: A Rare Case Study of Congenital Leukemia in One of the Separate Twins
Authors: Abdelaal Mohamed Mosaad , Youssef Walid Ali , Ahmed Amr , Akl Maher M.
Published: June 2024

BACKGROUND: Congenital leukemia is an exceptionally rare condition, with an incidence of 1 to 5 cases per million live births. Despite its rarity, the disease is clinically significant due to its severe manifestations and the need for tailored diagnostic and therapeutic strategies. Clinical features typically include hepatosplenomegaly, thrombocytopenia, and infiltrative cutaneous nodules. Recent advancements have identified the MLL gene as a critical player in leukemogenesis. A thorough understanding of the genetic and clinical aspects of congenital leukemia is essential for optimal patient management and genetic counseling.

CASE PRESENTATION: A 1-day-old male newborn, the first child conceived through in vitro fertilization (IVF) for this family, presented with neonatal tachypnea, hepatosplenomegaly, and thrombocytopenia. Genetic analysis revealed a chromosomal translocation involving the MLL gene. His twin brother, conceived simultaneously but developing independently, showed no signs of leukemia. The therapeutic approach included oxygen therapy, platelet transfusions, and supportive care. Follow-up assessments indicated significant improvement in hepatosplenomegaly and hematological indices.

CONCLUSION: This case highlights the clinical importance of congenital leukemia, particularly in the context of IVF-conceived pregnancies. The observed genetic discordance between the twins suggests the involvement of somatic mutations, chromosomal mosaicism, and epigenetic modifications. Recommendations for reducing the risk of genetic disorders in IVF-conceived pregnancies include preimplantation genetic testing, optimization of culture conditions, parental genetic screening, and ongoing research and education. This case represents the first documented instance worldwide of congenital leukemia occurring in one of the separate twins conceived through in vitro fertilization (IVF).

Authors: BELLİ Onur
Published: June 2024

Balkan Türklerini yaklaşık beş asırdır bulundukları vatan topraklarından sürgün eden 1912-1913 Balkan Savaşları, ardında derin yaralar ve acılar bırakmıştır. Bu kutsal topraklar ve ulu amaç doğrultusunda verilen mücadele büyük bir felaketle sonuçlanmıştır. Bu anlamda Balkan Savaşları, Balkan topraklarını acıyla kaplayan, kanla sulayan ve binlerce sivil halkın ölümüyle sonuçlanan bir savaş niteliği taşımaktadır. Balkan Savaşları’nın yaşandığı 1912- 1913 yılları arasında, binlerce asker ve sivil halk çatışmalar, salgın hastalıklar nedeniyle yaşamını yitirmiş savaşlar sırasında halk sefalet içinde kalmış ve Balkan Türkleri ilkel yollarla beş asırdır varlıklarını sürdürdükleri topraklarından sürgün edilmiştir. Türk tarihini derinden etkileyen, arkasında bir yıkım bırakan bu kanlı savaş ve Balkan Türklerine yapılan zulümler kaçınılmaz bir şekilde edebiyata yansımıştır. Ardında derin yıkım ve acı bırakan bu savaşın edebiyata yansıması düşünülemez. Bu açıdan 1912-1913 yıllarında Balkan Savaşları’nın Türk basınında kapladığı yeri görmek mümkündür. Ziya Gökalp, Aka Gündüz, Halid Fahri, Mehmet Âkif, Abdülhak Hamid ve Celal Sahir gibi birçok şair Balkan Savaşları’nı şiirlerinde konu edinmiştir. Balkanlar’da yaşanan zulümleri, şiirlerinde konu edinen şairlerden biri de Necmeddin Sahir Sılan’dır. Yazı hayatına şiirler kaleme alarak II. Meşrutiyet döneminde başlayan Necmeddin Sahir Sılan, hem Osmanlı İmparatorluğu’nun son dönemine hem de Türkiye Cumhuriyeti’nin kuruluşuna tanıklık etmenin getirdiği birikimini şiir ve düzyazılarında dile getirmiştir. 1912-1922 yılları arasında şiirler kaleme alan Necmeddin Sahir Sılan, şiirlerini dönemin önemli mecmua ve gazetelerinde yayımlatmıştır. Rübâb, Donanma, Türk Duygusu, Büyük Duygu, Servet-i Fünûn ve İnci/Yeni İnci mecmuaları ve Tasvir-i Efkâr, Tercüman-ı Hakikat, Anadolu’da Yenigün ve İleri gazeteleri bunlara örnek olarak gösterebilmektedir. Dönemin hafızasına yakından tanıklık etmiş olan Necmeddin Sahir’in şiirlerinde dönemlerde yaşanan savaşların, işgallerin ve halkı derinden etkileyen toplumsal olayların yansımasını görmek mümkündür. Bu bağlamda Necmeddin Sahir’in Trablusgarp Savaşı, Balkan Savaşları, Çanakkale Savaşı, Kurtuluş Savaşı gibi Türk tarihinde önemli yer edinen savaşları şiirlerinde konu edinmiştir. 1912 yılında yazı hayatına başlayan 1912-1913 yılları arasında İstanbul’da gazetecilik faaliyetleri yürüten Necmeddin Sahir Sılan, bu buhranlı yıllarda kaleme aldığı şiirlerinde Balkan Savaşları önemli yer tutmaktadır. Necmeddin Sahir, Balkan Savaşları sırasında harap olmuş şehirleri, insanların yaşadığı zulümleri kaleme aldığı şiirleriyle ölümsüzleştirmiştir.

Published: June 2024

Bread is one of the most important and basic food products consumed by people all over the world. The aging of wheat bread is a natural process that shortens its storage and sale periods and occurs under the influence of several factors, in particular due to the development of technically harmful microorganisms. Therefore, in the bakery industry, safe chemical preparations are widely used, which can inhibit the occurrence of microbiological defects and thus prolong the freshness of bread throughout the entire storage period. The aim of the work was to investigate the influence of organic acids on the microbiological, physicochemical and technological indicators of wheat bread. For the study, generally recognized microbiological and physicochemical methods were used to determine the quality indicators of raw materials and finished bakery products. It was found that flour of the highest and first grades, as the main raw material for the production of bread, always contains spore-forming bacteria, which, if the production technology and the temperature-humidity regime of storage are not followed, can be the cause of potato disease of bread. It was established that the addition of organic acids to flour during the production of wheat bread, on average, increases the titrated acidity of the finished product by 1 degree. According to physico-chemical parameters (moisture, porosity), the test samples of bread did not differ significantly, compared to the control sample, and these values were within the normative value. At the same time, the fragility of the test samples was, on average, 1.4 times lower than in the control bread.This indicates that products containing organic acids will be less likely to go rancid and have better organoleptic properties during storage. During the organoleptic evaluation of the test samples of bread, it was established that all of them met the satisfactory requirements for the main parameters, such as appearance, color and consistency, that is, they did not differ from the control sample. Therefore, the combination of organic acids and the creation of acidifying preparations for wheat dough will improve the quality of finished products and their shelf life.

Authors: Ovsienko S. M.
Published: June 2024

Mass consumption products such as a bread and bakery products have insufficient nutritional value due to the low content of complete proteins, dietary fibers, vitamins and minerals. The analysis of the nutritional value of bakery products shows the expediency of balancing their chemical composition, increasing the biological value, eliminating the deficiency of individual components due to enrichment with biologically active ingredients. A promising direction of increasing the nutritional value of bakery products is the inclusion of non-traditional plants raw materials in the recipe, which allows to increase their nutritional value, improve organoleptic and physicochemical indicators. The subject of the study is to increase the nutritional value of bakery products by using various technological methods, introducing raw materials of natural origin, in particular, non-traditional raw materials of plant origin, which is a natural biocorrector with a high content of biologically active substances. The purpose of the work was to conduct an analysis of literary sources devoted to scientific research on the use of non-traditional raw materials in baking. Analytical methods of research were used in the formation of the article. The use of non-traditional raw materials of vegetable origin in the production of bakery products enriches them with certain nutrients, diversifies the taste properties, but can have different effects on the characteristics of the dough and the quality of baked products. The use of non-traditional plant raw materials in the technology of bakery products to enrich them with useful nutrients and create products with health-promoting properties is substantiated.

Published: June 2024

A full-scale war and uncertainty about the sources of funding pose numerous threats to the future development of the social sphere in Ukraine. Currently, the expenditure side of Ukraine's budget is focused on priority financing of defence and military expenditures. At the same time, the decline in business activity as a result of Russian aggression and large-scale invasion is leading to a decline in budget revenues and the level of budgetary capacity. Under these conditions, the social sector of Ukraine does not receive sufficient funding and generally operates at the expense of international donors. The complexity of the situation necessitates a thorough analysis of the social sphere to identify the most priority areas of its development for the purpose of concentrated use of limited resources and efforts. The purpose of the article is to highlight the current problems of the social sphere development and to substantiate the directions of its analysis. The article analyses the standard of living of the population in the conditions of war, identifies current problems of development of the social sphere of Ukraine, and describes the priority areas of analysis of the social sphere. The article analyses statistical sources of the Ministry of Social Policy, the State Statistics Service, and the Pension Fund of Ukraine. The study used analytical and statistical-mathematical methods, the method of deduction in identifying development problems and systematisation and generalisation in identifying areas of analysis of the social sphere. Among the priority areas of analysis of the social sphere of Ukraine are the analysis of the standard of living of the population, analysis of GDP per capita and comparison of dynamics with other countries, analysis of access to education and medicine, analysis of employment and the labour market, assessment of social inclusion, analysis of socio-cultural development as part of the social life of citizens.

The article presents the results of research into the conceptual foundations of social inclusion policy, identifies its principles, goals and subjects in accordance with modern world practice. It has been proven that social isolation is an urgent problem of modern times in countries regardless of their level of development and carries with it significant negative socio-economic consequences for individuals, countries and the world community in the form of increased social tension and conflict, loss of human capital and GDP. Methodological aspects of the social inclusion basic principles and ideas implementation in the policy of rural development in the European Union are determined. It has been established that social inclusion as a tool for ensuring sustainable rural development is implemented at the pan-European, national and local levels within the framework of various components of institutional support for rural areas. Promotion of social inclusion is carried out through the implementation of numerous programs focused on the support of certain socially vulnerable groups of the population – youth, women, migrants, disability people, etc. The institutional basis for the systematic implementation of the social inclusion policy in rural areas is formed by the European network for rural development, which includes government institutions of various levels and stakeholders of sustainable rural development, represented through local action groups. It has been proven that the systematic implementation of social inclusion initiatives has become a guarantee of progress in achieving the goals of sustainable development in rural areas, the basis of the formation of a comfortable and conflict-free environment for life without any social, economic or other discrimination.

Published: June 2024

This work aims to study the dual-wavelength Q-switched fibre laser performances with erbium-doped fibre as the gain medium and the fibre Bragg gratings to allow stable switchable dual-wavelength states. Spider silk was used as an alternative biological material for saturable absorber. The spider silk as a saturable absorber was prepared by directly sandwiched between the surface of fibre ferrules. A dual-wavelength system operating at 1550 nm and 1560 nm was generated by modulating the polarisation controller to regulate the mode competition in the ring cavity. This allows for a flexible switch between individual wavelengths of 1550 nm or 1560 nm. The device operates at a wavelength of 1550 nm, with 26.63 kHz repetition rate and 9.45 μs pulse width. At a wavelength of 1560 nm, it produces a repetition rate of 24 kHz and a pulse width of 10.47 μs. The output demonstrated consistent stability throughout time, with no changes recorded. This indicates a stable signal-to-noise ratio of 41.12 dB and 34 dB for wavelengths 1550 nm and 1560 nm, respectively. This study presents the latest approach using spider silk as a saturable absorber to create a dual-wavelength Q-switched fibre laser. The laser is based on a fibre Bragg gratings device and has potential uses in terahertz signal and laser radar.

The project considers how improving accessibility to the collection through cataloguing, digitising and rehousing the slides will be of great benefit to the museum: uplifting their photographic collection by showcasing previously unseen works by well-known Irish photographers such as R. J. Welch, W. A. Green, and A. R. Hogg. Furthermore, it is argued that with increased accessibility, the value of lantern slides as important heritage resources will be revealed. The first half of this thesis looks to the history of lantern slides and their uses in natural history and science. The second half of the thesis is comprised of a hands-on report, featuring an outline of the work that was undertaken during my residency at the Ulster Folk Museum and the process through which I approached cataloguing, digitising and rehousing the collection in question.

This project is a demonstration of digital film scan editing techniques that can be freely used by any individual or organization, free from licensing costs and subscription fees. In addition to being a tutorial-style guide, the project features two films from the Canadian Warplane Heritage Museum that will used as examples for different edits to be applied, compared, and adjusted by readers following along with their own film scans. The goal of this project is not only to detail the process of creating restored digital versions of these films, but to make archivists aware of the possibilities once they have set up an editing environment that can be accurately documented and archived. Throughout the project, there is importance placed on storing the original scan, final result, steps in-between, and the exact script that was used to create the output in order to document and preserve the lineage of changes.

Birds generally rely on proactive anti-predator strategies when selecting nest sites, as they have limited options to adapt to changing levels of risk once incubation begins. Arctic waterfowl often nest colonially as an anti-predator strategy but dispersed-breeding species may use other proactive strategies, such as nesting in less risky areas. However, empirical links between spatial patterns of predation risk and nest habitat selection or success are needed to better understand how predator activity shapes Arctic waterfowl reproduction. Using activity data from the main cursorial nest predators, Arctic and red foxes (Vulpes lagopus, V. vulpes), and activity data from aerial predators, we evaluate the influence predator activity has on Canada goose (Branta canadensis interior) nest habitat selection and success, and how nesting phenology mediates these effects. By comparing habitat selection models fit to i) goose nest locations and ii) fox locations obtained from GPS-collars, we show that geese and foxes display nearly opposite patterns of selection for the same landscape traits. Geese selected sites that appeared to minimize their probability of encountering foxes while also maximizing their ability to detect foxes. Spatial predictions of fox activity revealed nests located in areas with higher probability of fox use had lower nest success, indicating fox space-use patterns reflect predation risk. Nests initiated earlier had a greater probability of nest success, but these patterns strongly depended on location; the benefits of nesting early were largely lost in areas of high fox activity. We also found a negative relationship between clutch size and incubation date, suggesting nests incubated later had higher rates of failure likely due, in part, to geese being in poorer body condition. Although nest success was lower in areas with high aerial predator activity, fox activity likely has a greater influence on goose nest spatial patterns due largely to movement constraints imposed by tundra landscape features on foxes but not aerial predators. Our study demonstrates the mechanisms by which nesting phenology and predator activity interact to shape bird reproduction, and provides an empirical demonstration of the value of incorporating temporal dynamics into the “landscape of fear” framework.
Asociación entre la anchura de la distribución del eritrocito y el síndrome metabólico
Authors: Rosas Alejandro
Published: June 2024

Introducción. El síndrome metabólico es considerado un trastorno inflamatorio crónico de bajo grado secundario a estrés endotelial y resistencia a la insulina. Existe evidencia de que la presencia de una respuesta inflamatoria persistente produce cambios en la producción de las células sanguíneas y estos pudieran conducir a una elevación de la Anchura de la Distribución del Eritrocito (ADE).
Objetivo. Determinar si existe una asociación entre el incremento de la anchura de la distribución del eritrocito y el síndrome metabólico o alguno de sus componentes.
Materiales y métodos. Realizamos un estudio de casos y controles en un grupo de sujetos que asistieron a la Unidad Médico Didáctica de la Universidad Autónoma de Aguascalientes entre enero de 2018 y junio de 2019. Analizamos variables demográficas, los componentes del síndrome metabólico y los parámetros de la biometría hemática de los casos y los de los controles. Se compararon mediante t de Student, X2 y Análisis de correlación de Pearson. Se consideró diferencia estadística con un valor de p<0.05 con dos colas.
Resultados. Incluimos a 168 pacientes (80 hombres, 88 mujeres) y 342 controles (144 hombres, 198 mujeres). El valor promedio de la anchura de la distribución del eritrocito para los casos fue de 13.84±1.12%, y el de los controles fue de 12.27±1.17% (p = 0.00001). El valor promedio del volumen plaquetario medio de los casos fue de 9.98±0.58 fl, y para los controles fue de 8.52±0.63 fl (p = 0.01). En el análisis de correlación encontramos únicamente una asociación inversa entre los valores de la anchura de la distribución del eritrocito y los del colesterol HDL de -0.38, (p=0.01).
Conclusiones. La anchura de la distribución del eritrocito y el volumen plaquetario medio de los pacientes fueron significativamente mayores que los de los controles.
Noches de hospital
Authors: Torres Ruiz Mariana
Published: June 2024

Noches de hospital es un diario poético sobre los avatares de la vida en enfermedad. Es la necesidad de nombrar los procesos que debe seguir un cuerpo enfermo, un corazón lastimado de tanto latir. No se enaltece la enfermedad en sí misma, si no la búsqueda del remedio, el camino hacia la salud. Diario de vida en el hospital, los días, en su trajín cotidiano, ir y venir de enfermos y médicos, pacientes y cuidadores, pero sobre todo de las noches, donde el dolor se agazapa en la oscuridad, y la incertidumbre lo acompaña. Conformado por cuatro apartados que indican la ruta que este corazón debe seguir, desde el tratamiento hasta la convalecencia, Mariana Torres Ruiz descubre palabras nuevas y crea su propio diccionario, a veces científico, otras veces doméstico, y rebautiza ‘desasosiego’ y ‘zozobra’ con nombres de medicamentos y terapias. Entonces, la esperanza en dosis de 20 mg. Si bien la autora se cuestiona dónde colocar este universo de palabras, la duda se resuelve en sus versos, en los poemas que, con mesura y tono grave pero no dramático, van transcurriendo como hojas de calendario, uno a uno, con la pausa precisa de un tiempo que se observa, desde adentro y desde afuera, para que no domine el miedo. En el extenso poema está presente la intimidad, el sigilo para que no se aterre nadie, para llorar en silencio, para que María no note los ojos enrojecidos. En cada parte, “Tratamiento”, “El pabellón 300”, “Noches de hospital” y “Convalecencia”, la poeta invita a sus madrinas para que la acompañen: Dolores Castro, Wislawa Simborska, Alejandra Pizarnik, Sylvia Plath y cierra Emily Dickinson, compañeras de ruta poética, trazada por el mapa de esta tradición literaria. En Noches de hospital las líneas poéticas ocupan el espacio que necesitan: a la izquierda, a la derecha a veces, al centro, se desconcentran, buscan su equilibrio. Líneas poéticas adelgazadas, a veces en una palabra. Líneas que gotean, que a veces se vuelven listado de un coctel para seguir viva. En cambio, al final, las palabras se agrupan hasta parecer cláusulas poéticas, versículos, poemas en prosa. ‘Necesitamos estar juntas’, dicen las palabras, dice el yo poético a su interlocutora. Noches de hospital es un murmullo, una delicada conversación. Es un conjuro contra el vacío. Entonces ¿el poema es una conversación o un monólogo? Es todo porque en él está el pasado, el presente, el porvenir a través de la memoria, del estar aquí y ahora escuchando los latidos de la noche.

Plant diseases significantly impact global agriculture, leading to substantial production losses and economic consequences. Timely disease detection can enhance crop yield, optimize resource utilization, reduce costs, and mitigate environmental effects, ultimately ensuring high-quality food production. Deep learning, specifically computer vision-based techniques, have proven invaluable in tasks like image classification, segmentation, and object detection. Deep Learning techniques such as You Only Look Once (YOLO) models are state of the art neural network algorithms used for accurate object detection. In this study, YOLOv5, YOLOv7 and YOLOv8 models were trained on CCL’20 dataset for citrus disease detection. Data augmentation techniques such as image translation, image scaling, flip, mosaic augmentations were implemented to improve the models’ performance during training phase. The model performance was evaluated using metric such as Mean Average Precision at 50% to 95% Intersection over Union score i.e. mAP@50-95. The results show that YOLOv8 model performs better than other variants and offers significant improvements over the benchmark performance from previous studies. The final hyper-parameter tuned model achieved 96.1% mAP@50-95 on testing data for citrus disease detection and mAP@50-95 of 95.3%, 96.0% and 97.0% for detection of Anthracnose, Melanose and Bacterial Brown Spot diseases, respectively. The trained model was able to detect single and multiple instances of same or different disease in an image showing the potential of recent YOLO models. The trained YOLOv8 model is deployed on Roboflow platform.
