Optimal hand surgery fellowship interview format
Authors: Dittman Lauren E. , Munaretto Nicholas F. , Rhee Peter C.
Published: June 2023

Context

The ideal format for residency and fellowship interviews has been consistently debated. Secondary to the COVID-19 pandemic, many institutions, including all hand surgery fellowship programs, transitioned interviews to an all-virtual format. In the past year, with ease of travel restrictions, some programs have transitioned back to in-person interviews, while others remain solely virtual. Hand surgery fellowship programs are continually assessing what are the best means for conducting these interviews, with little perspective regarding the applicant’s preferences.

Objectives

The purpose of this study was to examine hand surgery fellowship applicants’ perspectives regarding in-person and virtual interviews. It was hypothesized that applicants would value interpersonal relationships between faculty when deciding upon their ideal hand surgery fellowship, which would be easier to appreciate in-person.

Methods

All hand fellowship interviewees at a single institution were given a voluntary, electronic survey. The survey consisted of questions examining different aspects of the program’s interview day and supplemental resources. Responses were recorded after the in-person interview for the years 2018–2020. Questions were altered for the virtual 2021 and 2022 interviews. Questions were scored on a Likert scale.

Results

For the in-person interview cycles, there were 60/86 respondents (69.8 %). For the virtual interview cycles, there were 45/73 respondents (61.6 %). During the in-person interview cycles, applicants reported that the current fellows’ perspective talk was the most helpful component. Many applicants commented that they enjoyed meeting their potential co-fellows. The virtual interviewees felt that they had the best understanding of the program’s core values/culture and the worst understanding of faculty personalities and personal/family life. Twenty-nine (64.4 %) of virtual applicants would prefer an all in-person interview. Of the 16 respondents who did not advocate for a completely in-person interview, 56.3 % preferred the option for an in-person site visit.

Conclusions

Hand surgery fellowship applicants desire interpersonal interactions to better understand prospective fellowship programs, which can be difficult to convey with an all-virtual interview. The results of this survey can help guide fellowship programs as they continue to optimize in-person, virtual, and hybrid interview formats and refine recruitment resources.
A Note on Fractional Simpson Type Inequalities for Twice Differentiable Functions
Authors: Hezenci Fatih
Published: June 2023

In this paper, an equality is proved for twice differentiable convex functions involving Riemann–Liouville fractional integral. With the help of this equality, there are established several fractional Simpson type inequalities for functions whose second derivatives in absolute value are convex. By using special cases of the main results, previously obtained Simpson type inequalities are found for the Riemann–Liouville fractional integral.

Authors: Fernández Alejandro , Lang Andras , Gairí Margarida , González María Teresa , Cárdenas Francisco , Pons Miquel
Published: June 2023

Nuclear Magnetic Resonance is one of the most versatile structural biology tools. Its unique capacities remain unchallenged by the advances in other techniques, experimental, like cryo-electron microscopy, or computational, such as AlphaFold. In this perspective article we present the role played by various NMR techniques in the study of c-Src, a non-receptor protein tyrosine kinase that contains globular and intrinsically disordered domains. We show (i) how NMR helped chemical biology to discover the regulatory role of the Unique domain, (ii) its role in the characterization of the fuzzy intramolecular complex connecting the disordered region with the globular core through the SH3 domain, (iii) the identification of salt bridges connecting the main post-translational sites of the Unique domain with neighbor basic residues, and, (iv) the characterization of breathing motions and the independent dynamics of the two lobes of the kinase domain.

The need for flexible food packaging has increased substantially in recent years around the world due to the unprecedented growth in food consumption. Due to low cost and ease of processing, petroleum-based synthetic polymer packaging materials are being predominantly used for food packaging these days. To avoid contributing to environmental problems caused by ecological risks, consumers have been searching for alternatives to plastic food packaging due to the fact that plastics cannot be recycled and are not biodegradable. Therefore, bioplastics made from corn starch, which are biodegradable, can be one solution to these issues. The starch’s amylopectin and amylase composition has a significant impact on the polysaccharide’s characteristics. Corn starch (CS) is utilized as a food source for humans and other animals, but it also has many other applications in industry. Corn starch, on the other hand, has a few issues that need to be addressed through some modifications. Although starch-based packaging is expensive, they create less waste overall, which helps in the reduction amount of plastic pollution. A variety of natural and synthetic polymers – including polysaccharide-based materials like Kappaphycus alvarezii seaweed, collagen, alginate, chitosan, zein, cellulose, gelatin, various amino acids and polymeric materials like acrylic acid, polybutylene (PB), polyacrylic acid, polyethylene (PE), polyvinyl chloride (PVC), polyvinyl alcohol (PVA), and polycaprolactone (PCL) – are used as starch modifiers to produce polymers with a starch base that are completely biodegradable. These biopolymers have the potential to replacing petroleum-based polymers in a variety of commercial and industrial settings. Besides, corn starch nanocomposite films reinforced with nanocellulose have been investigated as a potential eco-friendly packaging material. Consequently, the effects of nanocellulose content on the mechanical, thermal, and barrier properties of corn starch-based films will be discussed in this work.
CarNum: parallel numerical framework for computational cardiac electromechanics
Authors: Liogky Alexey A. , Chernyshenko Alexey Yu. , Danilov Alexander A. , Syomin Fyodor A.
Published: June 2023

A new parallel numerical framework CarNum is presented for efficient coupling of mathematical models in multiphysics problems such as computational cardiac electromechanics. This framework is based on open source projects, which provide the core functionality of the platform. Computational cardiac electromechanics requires a complex pipeline of solving different types of ordinary and partial differential equations. Our framework allows one to implement different numerical schemes and provides more control in multiphysics coupling. This paper outlines a concept of the new platform and details of numerical modelling of cardiac electromechanics. First experiments with well-known cardiac electromechanics benchmarks show good agreement with other groups and decent parallel scalability.

ZERDÜŞTÎLERİN KUTSAL KİTABI AVESTA BAĞLAMINDA MEŞRU ve GAYRİ MEŞRU CİNSEL İLİŞKİLER
Authors: SULAR Mehmet Emin
Published: June 2023

Cinsellik, açlık, susuzluk gibi her insanda bulunan ve insanlığın ortaya çıkışıyla kendisinden bahsettiren içgüdüsel bir duygudur. Freud cinsel duygunun insanda aktif olma başlangıcını çocukluk dönemine kadar indirir. Ona göre çocuğun annesinin sütünü ve parmak emmesi cinsel aktivitenin başlangıcıdır. Buna rağmen çocuklarda cinselliğin olgunlaşmayla birlikte kendini yoğun olarak hissettirdiği söylenebilir. Cinsellik, bireysel bir ihtiyaç olmasının yanında toplumun varlığının devam etmesi için de önem arz etmektedir. Bundan dolayı tüm kutsal kitaplarda, mitolojik, edebi ve tarih kaynaklarında cinsellik hakkında bilgi bulmak mümkündür. Özellikle kutsal kitaplar, insanlığın devamını sağlayan bir duygu olarak cinselliği değerlendirmiş ve bunun tatmin edilmesi için bazı kurallar ortaya koymuşlardır. Kutsal kitapların cinsellik için belirlediği çerçeve, genellikle evlilik kurumu içerisinde bu duygunun karşılanmasıdır. Bunun dışında kalan ilişki şekilleri yasaklamış buna uymayanlara bazı cezalar öngörülmüştür. Bu kutsal kitaplardan biri de Zerdüştîliğin dini metni olan Avesta’dır. Avesta, evlilik sürecinde dahi cinselliğin nasıl olması gerektiği konusunda ayrıntılı bilgi vermiştir. Çalışmanın amacı Avesta’nın cinselliğe yaklaşımını, hangi cinsel ilişkileri meşru, hangilerini ise gayri meşru gördüğünü ortaya koymaktır. Sonuç olarak Avesta’nın cinselliğe önem verdiği ve bu duygunun meşru bir şekilde karşılanması konusunda yerine göre diğer dini metinlerle benzer bir yaklaşım sergilediği yerine göre kendisine özel bazı tercihlerde bulunduğu görülmektedir. Çalışmada literatür taraması yapılmıştır. Temel kaynak Avesta olmakla birlikte Zerdüştî dini geleneğine ait Ardâvîrâfnâme, Minûy-ı Hîred ve Pehlevi Metinlerinden de faydalanılmıştır. Bunun yanında konuyla ilgili modern döneme ait farklı kaynaklara da müracaat edilmiştir.
Londra Halkevi Üzerine Bazı Değerlendirmeler
Authors: ESER Gülşah
Published: June 2023

Londra Halkevi, genç Türkiye Cumhuriyeti’nin yurt dışında açtığı kültür kurumlarının ilk örnekleri arasında olma özelliğini taşıması yanında Halkevi olarak da tek örnektir. 1942-1950 yılları arasında faaliyet gösteren bu kurum Türk-İngiliz diplomatik ilişkilerinin geliştirilmesine katkı sağladığı gibi Türklerle İngilizlerin birbirilerinin kültürünü tanımasında da aracı bir rol oynamıştır. Öte yandan o dönemde İngiltere’de bulunan vatandaşlarımızın Türkiye ile temas kurduğu noktalardan biri olmuştur.
Bu araştırmanın öncelikli amacı özgün akademik çalışmalara konu olan Londra Halkevi’ni Dışişleri Bakanlığı Türk Diplomatik Arşivi’nde bulunan belgeler ışığında yeniden ele almaktır. Bu belgeler daha çok Londra Halkevi ile Cumhuriyet Halk Partisi (CHP) Genel Sekreterliği, Hariciye Vekaleti, Londra Büyükelçiliği ve çeşitli kurumlar arasında yapılan yazışmaları kapsamaktadır. Bu yazışmalar Londra Halkevi’nin kuruluş süreci, idare heyeti, üye sayısı, binası, bütçesi ve etkinlikleri gibi hususlara ilişkin pek çok ayrıntıya ulaşma olanağı sağlamıştır. Makalenin diğer bir amacı ise ulusal, yerel ve uluslararası basında bu kurum ile ilgili yer alan çeşitli haber/yazıların derlenerek literatüre kazandırılmasıdır.
Araştırmada literatür taraması, arşiv taraması ve doküman analizi yöntemleri kullanılmıştır. Elde edilen bulgulardan hareketle Londra Halkevi’nin Türkiye Cumhuriyeti’nin İngiltere ile geliştirdiği diplomatik ilişkilere ve özellikle bu ilişkilerin kültürel boyutuna önemli katkılar sağladığı sonucuna ulaşılmıştır. Bu merkezin, Cumhuriyet değerlerinin yurt dışında tanıtıldığı bir vitrin vazifesi görmüş olması da ulaşılan diğer bir sonuçtur.
Lost in temporal translation: a visual and visitor-based evaluation of prehistory displays
Authors: McDowall Felicity A.
Published: June 2023

Prehistory comprises millions of years and encompasses a diverse range of social, cultural, economic and technological practices. Despite its widespread public popularity, understanding of the chronology and developments of this vast expanse of human history is frequently anachronistic. Here, the author uses the results of museum visitor questionnaires and tracking surveys to assess public preconceptions of prehistory and engagements with museum displays. In addition, the article documents and explores 173 prehistory displays in museums in England, identifying trends in representation. The results point to some significant representational disparities affecting the display of prehistory and highlights some opportunities for reimagining museum prehistory displays.

The increase in consumption of goods and products, mainly of disposable products, at the global level has resulted in a considerable impact to the environment. Specifically, waste plastics can be associated with an extremely high social cost and can greatly affect the local environment when not properly discarded. The United Nations Environment Programme estimates that 6.4 million tons of garbage end up in the oceans at an alarming rate of 200 kg per second. Plastics represent 80 % of these wastes. This paper proposes the use of waste plastics in the production of hot mix asphalt (HMA) based on a process production implementation using the identify, define, optimize, and validate Six Sigma methodology for quality control assurance. The procedure involved consumer use requirements, material analysis, HMA design, production design, quality control processes, and, finally, the construction of test sections in two different countries in Latin America: Costa Rica and Bolivia. One of the challenges documented in the paper was the implementation of the waste material-modified HMA on small, local producer facilities while meeting all production requirements to ensure the success of the process. Also, based on circularity principles, the project represents a revolution regarding the implementation of a linear production system within a circular process that is partly intended to ensure that the footprint of waste plastics on the environment is reduced while taking advantage of the properties of the waste polymers to improve the performance of the modified HMA.
Effect of Lateral Load on the Mechanical Properties and Failure Modes of Sandstone Brazilian Discs during the Biaxial Splitting Test
Authors: Ma Chunde , Lv Zhi-hai , Liu Zelin , Guo Teng-fei , Wei Xin’ao
Published: June 2023

To study the mechanical properties and failure modes of the Brazilian disc under biaxial splitting loading, different stress ratios (i) (axial stress:lateral stress) i = 1:1, 2:1, 3:1, 4:1, and ∞:1 are experimentally applied in sandstone discs by a hydraulic servo-controlled testing machine equipped with a lateral loading device. Meanwhile, digital image correlation (DIC) and the FLAC3D are used to obtain the strain field and stress field evolution of the specimens. It was found that the presence of lateral pressure limits, the formation of horizontal tensile stress to varying degrees, and the axial peak loads decrease with the stress ratio. The failure modes that the rock discs underwent were shear failure, shear-tension mixed failure, and tensile failure as the stress ratio increased. The DIC results show that the maximum strain field gradually transitioned from the adjacent loading points of the discs to between two loading points in the axial direction with the stress ratio. In addition, the simulation results also demonstrated the transformation of the dominant stress in the stress field from tensile stress to shear stress with increasing lateral pressure.

Published: June 2023

The Confusion, Hubbub and Order Scale (CHAOS) – short form – is a survey tool intended to capture information about home environments. It is widely used in studies of child and adolescent development and psychopathology, particularly twin studies. The original long form of the scale comprised 15 items and was validated in a sample of infants in the 1980s. The short form of the scale was developed in the late 1990s and contains six items, including four from the original scale, and two new items. This short form has not been validated and is the focus of this study. We use five samples (N=10,898) from studies in Australia, the UK, and the USA, to examine the measurement properties of the CHAOS short form. We first compare alternate confirmatory factor models for each group; we next test between-group configural, metric and scalar invariance; finally, we examine predictive validity of the scale in each sample under different conditions. We find evidence that a two-factor configuration of the six items is more appropriate than the commonly used one-factor model. Second, we find measurement non-invariance across groups at the metric invariance step, with items performing differently depending on the sample. By contrast we find longitudinal measurement invariance in two of the three samples with multi-wave data collection on the CHAOS. Finally, we report inconsistent results in tests of predictive validity using family-level socioeconomic status and academic achievement as criterion variables. The results caution the continued use of the short-form CHAOS in its current form and recommend future revisions and development of the scale for use in developmental research.

¿Educando en igualdad? Análisis de la triada pornografía-discriminación-violencia. Feminidad y masculinidad en la pornografía convencional
Authors: Del Barrio-Álvarez Elena , Garrosa Eva
Published: June 2023

Dentro del feminismo se ha debatido desde los años setenta sobre el daño o beneficio que supone la pornografía en la lucha por la igualdad. Las feministas anti-pornografía la consideran una de las causas de la existente violencia contra las mujeres, mientras que las feministas pro-pornografía la contemplan como una consecuencia de la libertad de expresión, y un posible espacio de subversión y reivindicación de los derechos sexuales de las mujeres. A pesar de la existencia de este eterno debate, poco ha cambiado la pornografía; ni se ha reducido la violencia contra las mujeres, ni el post-porno ha podido igualar, ni menos desterrar, a la pornografía tradicional. Para poder romper la relación entre pornografía, violencia y discriminación es necesario que ambas posturas del feminismo encuentren un punto de convergencia, como la educación en igualdad. En esta comunicación se explorará la relación entre pornografía y roles de género transmitidos. Para ello se analizan las conductas permitidas y prohibidas en el ámbito. El marco teórico contemplado se basa en los textos de MacKinnon, Erika Lust, Sunstein y Gail Dines. Se emplea un enfoque fenomenológico para poder evaluar las características de la pornografía mainstreaming. Los instrumentos empleados para dicha aproximación son: las bases de datos sobre consumo de pornografía convencional (pornhubinsights, alexa, freewebsitereport y google analytics data) y las páginas con mejor posicionamiento (según alexa y freewebsitereport). Para llegar a los resultados se emplea un análisis del contenido latente, apoyado también con un análisis cuantitativo univariado. Las conclusiones se centran en cómo y hasta qué punto debería ser regulada la pornografía, teniendo en cuenta su impacto en la educación sexual de los/as más jóvenes.

[ES] LOS DOS CUERPOS DE CARLOS II // THE TWO BODIES OF CHARLES II
Authors: Mínguez Víctor
Published: June 2023

En las cortes europeas del siglo XVI coexisten dos modelos de cenotafios regios, ambos de tradición medieval. El primero muestra al monarca difunto yacente o arrodillado sobre la tumba; el segundo presenta el doble cuerpo del rey según la teología política que equipara la doble naturaleza de Cristo a la de los príncipes. En la tradición habsbúrgica predomina abrumadoramente el primer modelo, pero coincidiendo con la decadencia de la Monarquía Hispánica, y especialmente durante el reinado de Carlos II, encontramos en los virreinatos americanos en el último tercio del siglo XVII diversas imágenes propagandísticas que recuperan la idea del doble cuerpo, reforzada por imágenes emblemáticas singulares como soles y fénix. Como en la Edad Media y el Renacimiento, el doble cuerpo evidencia la pervivencia de la institución monárquica por encima de la muerte del rey o, como en este caso, de la dinastía.PALABRAS CLAVE: Carlos II, cadáver, retrato, poder, Nuevo Mundo. -- In the European courts of the sixteenth century there were two models of royal cenotaphs, both following the medieval tradition. The first of them showed the deceased monarch lying or kneeling on the grave; the second presented the double body of the king, following a political theology that equates the dual nature of Christ to the princes. In the Habsburg tradition clearly dominated the first model, but coinciding with the decline of the Monarchy, and especially during the reign of Charles II, we found in the American Viceroyalties different propaganda images that recover the idea of double body of the king, reinforced by singular emblematic images, like suns and the phoenix. As in the Middle Ages and the Renaissance, the double body of the king evidence the survival of the monarchy over the king's death or, as in this case, the end of the dynasty.KEY WORDS: Charles II, corpse, portrait, power, New Wor

Despite the progress in synthetic polymer industries, wood is one of the main materials in making musical instruments because of its unique characteristics. Many instrument makers try to improve the acoustic properties of wood by traditional treatments. In this study, the changes in the acoustic properties of walnut wood during the processes of fermentation pretreatment, water washing, and organic solvent washings were evaluated. For this, the samples were divided into two groups of 20. For the first group, de-extraction was started with fermentation pretreatment, while the second group samples directly underwent stepwise extraction, using hot water and ethanol-acetone solvents. The results showed a decrease in density, dynamic modulus of elasticity, and damping factor due to the soaking process. But the elastic stiffness did not change. The values of the acoustic coefficient and the acoustic conversion efficiency increased due to the soaking process. The values of density, dynamic modulus of elasticity, elastic stiffness, and damping factor decreased due to ethanol-acetone washing, while the acoustic coefficient and acoustic conversion efficiency showed a significant increase. In general, soaking process and ethanol-acetone washing with fermentation pretreatment improved the acoustic properties of walnut wood.

Published: June 2023

Green Velvet Material (PLON), which is prepared from polyester slices, has been called a green material based on its ester composition, its ability to be degraded, and the possibility of recovering the value of used material by reprocessing. PLON is expected to be used as a material for the padding layer of upholstered furniture. This paper presented a comparative study of traditional flexible polyurethane foam and Green Velvet Material as the upholstered furniture’s padding layer. The compression mechanical properties of Green Velvet Material and flexible polyurethane foam, such as indentation force deflection, support performance, compression set, and resilience property, were analyzed. The results showed that Green Velvet Material had lower surface hardness and higher comfort compared to flexible polyurethane foam. In terms of resilience, both high-density and low-density Green Velvet Material performed better than the foam control group, but Green Velvet Material had a poorer ability to regain its shape after prolonged pressure. The 30 kg/m3 density Green Velvet Material was the closest to the compression and resilience properties of flexible polyurethane foam. The conclusions provide theoretical data for the effective and reasonable application of Green Velvet Material in upholstered furniture.
Physical and mechanical properties of laminated wood made from heat-treated Scotch pine reinforced with carbon fiber
Authors: Percin Osman , Uzun Oğuzhan
Published: June 2023

Laminated veneer lumber (LVL) and reinforced laminated veneer lumber (RLVL) with carbon fiber were produced from heat-treated Scotch pine (Pinus sylvestris L.) wood using phenol formaldehyde (PF), polyvinyl acetate (PVAc), and polyurethane (PU) resins. Wood veneers were subjected to heat treatments at 150 °C, 170 °C, or 190 °C for 2 h before lamination. The effects of the reinforcement, heat treatment temperatures, and resins on the properties of the LVL and RLVL were analyzed. Density, equilibrium moisture content (EMC), modulus of rupture (MOR), and modulus of elasticity (MOE) were evaluated. The results showed that MOR and MOE values of solid wood and LVL specimens decreased with increasing treatment temperature. However, reinforcement with carbon fiber increased both MOR and MOE. In addition, the density values of the all RLVL specimens improved, and the EMC altered significantly for all test specimens. Compared to solid samples, the highest MOR values increased by approximately 21% in PF-RLVL samples. Similarly, the highest MOE values increased by 31% in PF-RLVL samples. In conclusion, carbon fiber, one of the most used fabric types in composites, could be utilized in the manufacture of reinforced LVL with heat-treated veneers.

Вступ. Підприємницькі наміри молоді — це запорука прогресивного інноваційного розвитку та вирішення нагальних суспільних проблем. Особливо актуальним це є для України — молодої демократії, яка потерпає від зовнішньої агресії та потребує відновлення економіки.Проблематика. Підприємництво — це не тільки знання й навички, а й спосіб мислення та поведінки. Важливуроль у цьому відіграють університети: формування світоглядного бачення студентів, генерування та апробація власних бізнес-ідей. Досвід та потенціал українських університетів в цій царині залишається недостатньо вивченим.Мета. З’ясування ролі університету як предиктора формування підприємницьких намірів на прикладі України задля розробки рекомендацій та пропозицій щодо формування екосистеми підтримки підприємництва, зростання підприємницької активності молоді.Матеріали й методи. Інформаційним матеріалом слугували результати опитування студентів у різних регіонах України на базі творчого розвитку методики міжнародного проєкту GUESSS (Global University Entrepreneurial Spirit Students’ Survey). Для обробки застосовано пакет програм SPSS, використано методи системного аналізу, гіпотетичнодедуктивний метод, аналіз таблиць спряженості, тісноти взаємозв’язків та ін.Результати. Роль університетів у формуванні підприємницьких намірів в Україні є низькою, система підтримки підприємництва засвідчила свою слабкість і несформованість. Частковий вплив на рівень підприємницької готовності мають освітня та культурна складові, які рекомендовано зміцнювати. Фінансова та концептуальна складові потребують корекції інструментарію з урахуванням кращого світового досвіду.Висновки. Стратегічним завданням є формування інституціонального середовища розвитку молодіжного та академічного підприємництва, поширення академічних бізнес-інкубаторів, студентських підприємницькоорієнтованих гуртків, проєктних груп, бізнес-клубів тощо.

The article focuses on the issue of highlighting the approaches being tested in contemporary migration studies to demonstrate their limits – conceptual, methodological, and methodical – as analytical tools. The three most popular research perspectives, namely positivism, relativism, and critical realism, are taken as a basis. The author substantiates the idea that the approach accumulates a much broader context than just the instrumental one, which correlates to the realization of an exclusively methodical function. Since by choosing one of the forms of analytics, scholars outline the ontological and epistemological framework of the methodology in the study of migration. Based on the key provisions (principles) of each approach, the author characterizes them as general scientific and specialized tools (for migration scholars) and identifies the different by nature shortcomings and opportunities for applying the obtained results. A particular focus is on demonstrating examples of research works that test these approaches. It is argued that positivism and relativism are monofactorial, less critical and more superficial (flatness) approaches compared to critical realism, characterized by stratified ontological realism, methodological pluralism, and judgment rationality. It is shown that the reasons for the popularity of positivist and relativist types of thinking are the methodological possibility of simplifying political issues and applying knowledge about migration to legitimize certain political beliefs and actions, on the one hand, and their deep internal hierarchization, which provides flexibility and opportunities for improvement, on the other. Finally, the author emphasizes the prospects for further research focusing on the scientific (revision of positivism and relativism under the necessities of the present), philosophical (rethinking the epistemological and practical components of the approach, balancing them) and practical (the need for higher representativeness of research conducted within the framework of critical realism) dimensions of migration issues.
Confirmation of the Presence of the Dolichophis caspius (Serpentes, Colubridae) in Vinnytsia Region — the Westernmost Locality of the Species in Ukraine Near its Northern Species Range

Published: June 2023

For the ongoing range shifts under climate change, it is essential to have reference information on the current presence of the species. In recent years, there has been an increase in observations of thermophilic reptiles outside their historical range in Ukraine. The distribution of the Caspian whipsnake, a common snake in southern Ukraine, appeared to be poorly documented at the northern edge of its range due to low density under sub-optimal conditions at the edge of the range. Here we provide verified observations of the Caspian whipsnake from the Mohyliv-Podilsky (formerly Yampil) district of the Vinnytsia region. These data considerably extend and specify the north-western limit of the range and, together with accompanying data on the frequency of species observations, support the hypothesis of a northward shift in the range of the species and/or a strong recent increase in the abundance of the species.
Is It Really Safe to Discontinue Antiplatelet Therapy 12 Months After Percutaneous Coronary Intervention in Patients with Atrial Fibrillation?
Authors: Abdulrahman Balen , Jabbour Richard J , Curzen Nick
Published: June 2023

The prevalence of AF in patients with coronary artery disease is high. The guidelines from many professional groups, including the European Society of Cardiology, American College of Cardiology/American Heart Association and Heart Rhythm Society, recommend a maximum duration of 12 months of combination single antiplatelet and anticoagulation therapy in patients who undergo percutaneous coronary intervention and who have concurrent AF, followed by anticoagulation alone beyond 1 year. However, the evidence that anticoagulation alone without antiplatelet therapy adequately reduces the well-documented attritional risk of stent thrombosis after coronary stent implantation is relatively sparse, particularly given that very late stent thrombosis (>1 year from stent implantation) is the commonest type. By contrast, the elevated risk of bleeding from combined anticoagulation and antiplatelet therapy is clinically important. The aim of this review is to assess the evidence for long-term anticoagulation alone without antiplatelet therapy 1 year post-percutaneous coronary intervention in patients with AF.

Authors: López Darwin , Linares Carlos , Figueredo Edith
Published: June 2023

El presente trabajo muestra el estudio del proceso de extracción de hierro proveniente de lodos rojos a través de su lixiviación con ácido sulfúrico (H2SO4) bajo un diseño de experimentos factorial de dos niveles con cuatro factores (24). Los factores analizados en este trabajo fueron: temperatura de reacción, tiempo de contacto, concentración del ácido y relación líquido a sólido. Se observó que la temperatura de reacción es el factor con mayor incidencia en la cantidad de hierro extraída (80,89%), seguido de la concentración de ácido (3,54 %). La interacción de segundo orden (relación líquido a sólido y temperatura de reacción), de tercer orden (concentración, tiempo y temperatura de reacción) y  cuarto orden (concentración de ácido, tiempo de contacto, relación líquido-sólido y temperatura de reacción) afectan de manera significativa la variable respuesta. En base a los factores e interacciones más significativas, se seleccionó como mejor condición para la lixiviación: 30 %v/v de ácido sulfúrico, 3 horas de reacción, relación líquido a sólido 30 mL/g y temperatura de 100 ºC.
