We present time-dependent percent and quantum yield measurements of a photoredox-catalyzed coupling reaction between 1,4-dicyanobenzene and N-phenylpyrrolidine. We also use transient absorption spectroscopy to examine the kinetics within the reaction and use kinetic modeling to extract rate constants and predict how changes in rate constant will impact the quantum yield.

The outstanding capacity of aquaporins (AQPs) for mediating highly selective superfast water transport1-7 has inspired recent development of supramolecular monovalent ion-excluding artificial water channels (AWCs). AWC-based bioinspired membranes are proposed for desalination, water purification, and other separations applications8-18. While some recent progress has been made in synthesizing AWCs that approach the water permeability and ion selectivity of AQPs, a hallmark feature of AQPs – high water transport while excluding protons has not been reproduced. We report on a class of biomimetic, helically folded pore-forming polymeric foldamers, that can serve as long sought-after highly selective ultrafast water-conducting channels exceeding those of AQPs (1.1 × 1010 H2O molecules/s for AQP17), with high water over monovalent ion transport selectivity (~108 water molecules over Cl- ion) conferred by the modularly tunable hydrophobicity of the interior pore surface. The best-performing AWC reported here delivers water transport at an exceptionally high rate, 2.5 times that of AQP1, while concurrently rejecting salts (NaCl and KCl) and even protons.

Published: April 2021

A Ni/photoredox-catalyzed enantioselective reductive coupling of styrene oxides and aryl iodides is reported. This reaction affords access to enantioenriched 2,2-diarylalcohols from racemic epoxides via a stereoconvergent mechanism. Multivariate linear regression (MVLR) analysis with 29 bioxazoline (BiOx) and biimidazoline (BiIm) ligands revealed that enantioselectivity correlates with electronic properties of the ligands, with more electron-donating ligands affording higher ee’s. Mechanistic studies were conducted, lending support to the hypothesis that the electronic character of the ligands influences the enantioselectivity by altering the position of the transition state structure along the reaction coordinate. This study demonstrates the benefits of utilizing statistical modeling as a platform for mechanistic understanding and provides new insight into an emerging class of chiral ligands for stereoconvergent Ni and Ni/photoredox cross-coupling.
The Ludo Mix and the Loss of In-Game Narrative: A Case Study of the Final Fantasy XV Universe
Authors: Bjarnason Nökkvi Jarl
Published: April 2021

Employing the Final Fantasy XV Universe as a case study, this article examines how the changing climate of game development, in tandem with established media mix strategies, contributes to the emergence of the ludo mix as media ecology. Through a comparative analysis of the climate of modern game development and the adoption of media mix strategies, the case is made that these two distinct phenomena intersect to create novel challenges and incentives for a particular kind of game development. This has resulted in the strategic outsourcing of Final Fantasy XV’s in-game narrative to outside the ludic sphere, and negatively affected the game’s critical reception. These findings posit challenges and opportunities for the future of the ludo mix, noting that the evolving technological, aesthetic, and economic climate of game development continues further down the same path, while simultaneously advocating for the ludo mix as a framework for better understanding the disproportionate load imposed on media via transmedia collaborations.
Characters in Fire Emblem Three Houses: A Ludo Mix Perspective
Authors: Blom Joleen
Published: April 2021

The article focuses on how dynamic game characters create friction in a ludo mix strategy consisting of primarily ludic media, disturbing the narrative coherency that trans- or cross-media strategies strive for. In particular, dynamic game characters, with a development structure that the player influences, cause narrative inconsistencies with the character’s transmedia appearances. Yet, in Japanese media and ludo mixes, character proliferation is the norm so that different versions of the same character can exist without any issues of narrative coherency. Through a case study of the Fire Emblem: Three Houses ludo mix, this article argues that the Japanese concept of the kyara, a proto-character, demonstrates to be an excellent means to avoid a clash between the dynamic game character in one work and its appearance in another work. It concludes that through the use of the kyara, the IP owner avoids any clash between the dynamic game character’s appearance in its source work and its appearance in other ludic works, thereby giving the impression that the player’s agency over the dynamic game character stays intact.
ПЕРЕКЛАДАЦЬКІ ІНТЕРПРЕТАЦІЇ ЗАГОЛОВКІВ ЦИКЛУ ГУМОРИСТИЧНИХ ОПОВІДАНЬ М. БОНДА
Authors: Володарська М. В.
Published: April 2021

У статті зроблено спробу проаналізувати характерні ознаки гуморис- тичного складника заголовків циклу М. Бонда «Пригоди ведмедика Падінгтона», визначити особливості відтворення комізму і причини його можливих втрат в українській та російській перекладних версіях, окрес- лити межу проникнення етноспецифічного гумору в тексти літератури для дітей. Вибір об’єкта дослідження зумовлений намаганням подолати протиріччя між наявністю розлогого літературного матеріалу (13 книг, 99 оповідань) та тривалим ігноруванням потенціалу тексту науковою спільнотою. Короткий огляд надбань з теорії заголовку (С. Кржижанов- ський, У. Еко, В. Кухаренко, А. Еткінд) дозволив визначити такі риси назв, як амбівалентність, полісемантичність, здатність акумулювати головний концепт художнього твору тими причинами, що значно усклад- нюють розкодування і ретрансляцію жарту. Лінгвістичний гумор завжди чинить опір перекладачеві, оскільки вимагає збереження не лише змісту, але і форми повідомлення, тому пошук найбільш прийнятних алгоритмів досягнення еквівалентності становить пріоритетне значення. Попри позірну прозорість сюжету, заголовки текстів М. Бонда поде- коли акумулюють цілий кластер соціокультурних уявлень, породже- них актуальними для Британії періоду 1950–1960-х років питаннями «інакшості». Концепт “trouble” є визначальним для циклу «Пригоди ведмедика Падінгтона». Відповідний концепт реалізується в низці назв (“A Bear in Hot Water”, “Sticky Time”, “Paddington in a Hole”) за посеред- ництва етноспецифічних алюзій та каламбурів; намагання відобразити ці нюанси виводить наратив М. Бонда на межу перекладності. Прагнення І. Бондаря-Терещенка до максимальної еквівалентності не завжди рів- нозначне прозорості англійського гумору для маленького читача; наро- щування експресії і додавання жарту А. Глебовською та К. Сиверце- вою спричиняє зміну тональності й наративного фокусу каламбурних утворень окремих заголовків. Відмінні продуктивні моделі відтворення гумору можуть бути результатом різних уявлень про специфіку дитя- чої книги. Питання як та якою мірою слід виводити у заголовок жарт, заснований на реаліях, залежатиме від вибору перекладачем стратегії «одомашнення» комічного чи збереження національного колориту.
Intoxicación por cianuro secundaria a exposición dérmica e inhalatoria no intencional: Reporte de caso y Revisión de la Literatura.
Authors: Espinosa Jonathan , Hernández M Sebastián , Laguado C Vivian M , Valverde G Emiro Nel , Núñez C Daniel Mauricio
Published: April 2021

Introducción. El Cianuro es un químico de fácil obtención en el mercado utilizado en varias industrias como la producción de insecticidas, fotografía y joyería. Los casos de intoxicación debidos a este compuesto tienen una alta tasa de mortalidad, sobre todo aquellos en los que no se administran de manera oportuna los antídotos. Esto es aplicable tanto a países industrializados como a los países en vías de desarrollo, lugares donde no se cuenta con recursos suficientes para el manejo de estas situaciones medicas complejas, como es el caso de nuestro medio, donde la incidencia de este tipo de intoxicaciones no es clara y puede estar subregistrada, reportándose dentro del grupo de intoxicaciones por sustancias químicas, siendo con intencionalidad suicida la mitad de los casos y la mayoría en hombres.

Objetivo. Conocer y manejar de manera adecuada los casos de intoxicación por cianuro, resulta de gran importancia que en los servicios de urgencias se tenga claridad sobre los aspectos fisiopatológicos y clínicos involucrados y la disponibilidad para uso de sustancias como el nitrito de sodio, el nitrito de amilo, el tiosulfato de sodio y la hidroxicobalamina como parte del tratamiento de estos pacientes, compuestos que no están habitualmente disponibles en nuestro país, siendo el azul de metileno el antídoto de elección por su disponibilidad en nuestro medio.

Metodología. Se trata de un reporte de caso de una paciente con intoxicación por cianuro secundaria a exposición dérmica en la fundación santa fe de Bogotá en 2020 y revisión de la literatura.

Resultados. Reportamos el caso de una paciente de 68 años, quien sufre una exposición involuntaria a cianuro por lo cual ingresa al servicio de urgencias con síntomas inespecíficos secundarios a dicha exposición, con evidencia de acidemia metabólica como principal hallazgo paraclínico.  Se documenta la evolución clínica y de la información aportada por el laboratorio y las medidas disponibles utilizadas para su manejo.

Conclusión. Exponemos un caso de intoxicación por cianuro por vías poco comunes en nuestro medio, las medidas utilizadas y las limitaciones que observamos al enfrentarnos a un escenario que potencialmente llevaría a la muerte a la paciente.

Published: April 2021

The subject of the study is the indirect financing of sports development abroad through tax incentives. This paper aims to analyze and summarize foreign experience of tax approaches to the sports development and to substantiate the possibility of its application in the Russian Federation. The following methods were used: content analysis of scientific papers and the legal framework related; comparing the different sports funding models and the tax instruments used in the analyzed countries to promote sports; logical synthesis to gain insights and form recommendations. Sports currently play an important role in addressing both social and economic challenges, which reinforces governmental regulation. The financing models for sports development applications abroad are examined. Models have been found to differ by the use of direct and indirect methods of sports financing methods, including tax incentives. The experience of tax incentives application for sports promotion in the United States, Germany, the Netherlands, Hungary, and Belarus has been analyzed, similarities and differences of the ways goals are achieved have been identified. Possibilities for applying foreign experience in tax incentives for the sports development in the Russian Federation have been identified. Conclusions have been made on the need to further analysis of foreign experience in order to improve methods of indirect financing of sports development. The economic rationale for the proposed tax regulation in sports development should be ensured to prove feasibility thereof.
The influence of treatment by different microorganisms on the development of alternariosis (Alternaria solani) and the potato yield
Authors: Aldiba Adaa Shahat , Eskov Ivan Dmitrievich
Published: April 2021

Alternariosis is a dangerous disease of potatoes, which reduces its production in Russia and abroad. Due to the intraspecific variability of the pathogen, wide symptoms and a long period of immunity, it is very difficult to diagnose the disease and take protective measures. As a biological method of protection, eight microorganisms have been tested with an effect on alternaria (Alternariasolani (Ell. Et Mart.). Sor.); these bioagents were screened for their disease inhibitory activity in the field. Studies have shown that the treatment of potatoes with Trichoderma sp. and Bacillus thuringiensis showed a high value for the increase in plant size in both cultivars (44.6, 43.1 cm for Romano), (47.6, 42.7 cm for Labella) compared to control. The number of stems in plants treated with Pseudomonas jessenii was higher (4.0, 4.4 pcs) than in the control of both varieties. Potato processing Trichoderma sp. and Bacillus thuringiensis reduced the spread of the disease in the studied cultivars (23.0, 24.6% for Romano), (17.4, 20.3% for Labella) compared to controls. Treatment of potatoes with Trichoderma sp. and Bacillus thuringiensis increased the weight of the marketable yield on both varieties (18.1, 17.1 t / g for Romano), (19.8, 19.2 t / g for Labella) compared to the control.

Authors: Vasilenko Irina Olegovna , Moskalenko Sergey Petrovich
Published: April 2021

Reasil® Humic Vet is a liquid water-soluble feed additive with complex action. The aim of our research was to study the effect of the liquid feed additive "Reasil® Humic Vet" on the productive qualities and the digestibility of nutrients in compound feed by laying hens. The drug was drunk for 14 days with a break between courses of 7 days at a dose of 0.25, 0.50 and 0.75 ml / 1 liter of water. The highest egg production was obtained in chickens, the second experimental group -84.69%. The weight of 1 egg in this group also turned out to be higher than -63, 10 g. All this led to an increase in the egg weight to 31.09 kg, while reducing feed costs to 2.17 kg. The digestibility of organic matter in the experimental groups was 75.45, 75.44 and 75.37%, which is significantly higher than in the control group by 0.66, 0, 67 and 0.59%, respectively (P <0.05). The drug used with a high degree of reliability stimulated an increase in the digestibility coefficients of protein, fat, fiber (P <0.01) in chickens from 1 and 2 experimental groups. Increasing the amount of the supplement to the maximum dose did not significantly affect protein digestibility. Fat, fiber and dry matter in general in the 3rd experimental group had digestibility coefficients, the difference of which with those of the control group was confirmed by biometric processing (P <0.05 and 0.01).
