Published: May 2023

A hanseníase é uma doença crônica e infecto-contagiosa que possui diversas manifestações clínicas dermatológicas e neurológicas. Trata-se de um problema de saúde pública no Brasil devido aos elevados índices de novos casos. Assim, o Brasil é o segundo país com maior número de casos da doença no mundo e, portanto, necessita de uma vigilância epidemiológica efetiva. Dessa forma, o objetivo deste estudo é estimar a taxa de prevalência oculta da hanseníase em Alfenas-MG de 2006 a 2020. Realizou-se, primeiramente, um estudo quantitativo e descritivo dos casos de hanseníase diagnosticados no município de Alfenas-MG a partir de 2001, provenientes da análise de dados secundários obtidos no Sistema de Informação de Agravos de Notificação. Para o cálculo da taxa de prevalência oculta, foi utilizado o método proposto por Suárez e Lombardi e indicado pelas Organizações Pan-Americana e Mundial de Saúde/ Organização Mundial de Saúde. Comparando o resultado das décadas têm-se: queda de 82,16% de diagnósticos entre a primeira (n=314) e a segunda década (n=56); alta prevalência de pacientes multibacilares em ambas; incapacidade grau I e II em 55,10% dos pacientes na primeira década e, na segunda, 23,21% apresentaram incapacidade grau I e 0% incapacidade grau II; aumento de 1.093,70% da taxa de prevalência oculta da segunda década em relação ao período de 2006 à 2010. Destacamos que este estudo é essencial para que medidas de prevenção, controle e eliminação sejam elaboradas pelos órgãos competentes a fim de erradicar ou minimizar a hanseníase no sul de Minas Gerais.

Conclusões: O estudo evidenciou que os enfermeiros que atuam no Programa de Assistência e Internação Domiciliar são gestores dos cuidados paliativos no domicílio, tendo a equipe multiprofissional e a família como aliados e suporte em seu processo de trabalho direcionados ao indivíduo em cuidados paliativos e enfrentam desafios de diferentes naturezas em sua prática, sendo eles relacionados a  aspectos  como:  a operacionalização  da  rotina  de  trabalho diante das diversas demandas do território local;  ao  campo  de  atuação  e  a  rede  deficitária  de  suporte  ao  paciente e a família;  e  de comunicação/acolhimento  aos  pacientes  e  familiares  em  um  cenário  que  favorece a  fragilidade  emocional de todos os envolvidos nesse processo de cuidado.
Fracture: Abortion Law and Politics After Dobbs
Authors: Rebouché Rachel , Ziegler Mary
Published: May 2023

Before Dobbs v. Jackson Women’s Health Organization—the case that overturned Roe v. Wade—almost everyone assumed that polarization would continue to define the abortion debate: once states could ban abortion before viability, half the country would criminalize it and half the country would not. The assumption has been that states would prohibit or permit abortion in ways that correspond to political beliefs. This Article demonstrates the limitations of that narrative both as a matter of history and in the current political moment. The future of abortion law and politics is one of fracture. Particularly for the anti-abortion movement, once-foundational priorities will come under pressure, shifting legislative and litigation strategies at the state and federal levels. We map fracture along three critical fault lines: the legal recognition of fetal personhood, the definition of abortion, and the movement for reproductive justice. First, the majority opinion in Dobbs wields the rhetoric of neutrality to advance a singular understanding of history and tradition, defined by efforts to overturn Roe. We show how Dobbs charts a course for recognizing fetal personhood but with the costs of contestation and undermining the majority opinion’s purported neutrality. Significantly, Dobbs has exposed divisions in the anti-abortion movement, which has refashioned its support for fetal personhood in new state laws, raising questions about enforcement inside and outside state borders. Second, Dobbs incited a new struggle over what abortion entails, and both abortion supporters and opponents will contend with whether recent bans include fertility services or specific contraceptives as well as how bans apply when patients face medical emergencies. At the same time, because the nature of early abortion care has changed—available through mailed pills taken at home—abortion will be harder to police and stop. Third and finally, fracture within the abortion-rights movement will become more pronounced as the call for reproductive justice takes on different importance. The end of Roe will realign priorities in litigation, policymaking, and resource allocation around broader issues of social justice. The coming era will be defined by divergent views about who may speak on behalf of those neglected by the law and what it means to recognize the basic humanity of the most marginalized in the country. But as those views are tested for their political and practical feasibility, we should expect abortion antipathy as well as abortion support to be less tethered to party affiliation and more reflective of abortion care on the ground.
GUERRA AOS TRAFICANTES

Published: May 2023

A pós-modernidade acentua a alteridade e representações de insegurança, fortalecendo o populismo punitivista. Uma das áreas críticas dessa expansão é a política criminal antidrogas. Segmento doutrinário tem apontado a ineficiência e ilegitimidade desta política, além de seus efeitos reversos para as políticas de atenção à saúde e para a cidadania de grupos socialmente marginalizados. Esse trabalho tem o objetivo de analisar os custos humanitários associados à política criminal antidrogas e se eles se justificam à luz do paradigma constitucional brasileiro. Quanto à metodologia, utiliza-se do raciocínio indutivo com uso de revisão bibliográfica em periódicos (Qualis A1) dos últimos 5 anos e de decisões judiciais sobre o tema. Demonstra-se como a política criminal antidrogas é uma manifestação autoritária de direito penal do inimigo, fundada na lógica do direito penal de autor, tratando os traficantes de drogas como “não-pessoas”. Avalia-se o impacto desta política no truculento panoptismo da atuação policial em áreas socialmente periféricas, promovendo o racismo institucional, a superpopulação carcerária e os associados problemas humanitários. Discute-se o efeito desta política no próprio fortalecimento do crime organizado que busca combater. Conclui-se quanto à violação ao princípio da proporcionalidade na ponderação do custo-benefício da política criminal antidrogas, apresentando-se propostas para um realinhamento ao sistema de garantias fundamentais da intervenção punitiva.

Uma série de estudos mostram a desigualdade no acesso às tecnologias de informação e comunicação entre classes sociais e entre países desenvolvidos e subdesenvolvidos. Dada a relevância do acesso à internet no cenário de isolamento social imposto pela Covid-19 com a paralisação das aulas presenciais, objetiva-se discutir o acesso à internet como direito humano fundamental para a concretização do direito de acesso à educação, para que alunos de escolas públicas e privadas brasileiras possam ter igualdade de oportunidades e igualdade de acesso à educação e aos benefícios da rede mundial de computadores. Trata-se de uma pesquisa descritiva, apoiada no método dedutivo e dialético, com amparo na literatura e nas informações de organismos internacionais e nacionais. Neste contexto, conclui-se que a Covid-19 expôs a face cruel da desigualdade social e de acesso à internet, o que refletirá dramaticamente no futuro das crianças e jovens excluídos do sistema educacional, por não disporem de internet de qualidade e computadores para exercerem o direito à educação. Tais questões sustentam que, uma parcela significativa da população estudantil brasileira está refém do descaso da área de educação federal, estadual e municipal. Razão pela qual o presente estudo se posiciona no sentido de o direito de acesso à internet constar do rol de direitos sociais para que todos possam ter igualdade de oportunidades.

Published: May 2023

O conceito de família tem evoluído, acompanhando a própria evolução da sociedade e as novas formas de relacionamento entre as pessoas. Da mesma forma, a noção de filiação também evoluiu, principalmente com a introdução de técnicas de reprodução humana assistidas, constantemente desenvolvidas pela ciência, e que geram consequências diretas no direito e no biodireito. Em verdade, o desejo de gerar um filho permeia aspectos importante da pessoa e faz com que a ciência crie técnicas que tornam isso possível, até mesmo para depois da morte da pessoa. Nisso se tem a reprodução assistida póstuma ou post mortem, técnica em que se tem a implantação do material genético ou do embrião criopreservado após a morte do cônjuge/companheiro, o que traz uma série de consequências, problemas e discussões no campo da psicologia, da sociologia, e, principalmente, da bioética, do biodireito e no direito. No específico, este trabalho visa trazer à discussão os efeitos previdenciários da reprodução assistida post mortem.

Palavras-chave: família; filiação; reprodução humana assistida post mortem; efeitos previdenciários; pensão por morte.

El objetivo principal de este trabajo de investigación es problematizar acerca de lo que consideramos son los elementos básicos para un ejercicio docente sistematizado. En un primer momento analizaremos la importancia y los límites de considerar aspectos lúdicos en el aula; consideramos que uno de los elementos más importantes para la buena docencia es la de fomentar la motivación y el interés en el alumnado; otro factor ineludible es considerar la inclusión de otras disciplinas y temas con vinculación a los problemas políticos como económicos sociales, filosóficos, culturales históricos entre otros para poder comprender íntegramente las vicisitudes que enfrenta el derecho contemporâneo; una comunicación asertiva en la que se presupone que va a haber un contexto de escucha activa por parte de todos los implicados en el marco de un lenguaje correcto, directo y respetuoso; la responsabilidad qué tiene el docente de tener una visión que esté sustentada en diferentes perspectivas teóricas y no sólo unas cuentas, es decir, la transparencia ideológica de la persona académica; la necesidad de incluir una flexibilidad en la evaluación, el compromiso ético y político de la docencia de labrar un camino hacia la emancipación y, por supuesto, la importancia de la congruencia, es decir, que el docente cuente con un paralelismo entre lo que dice y lo que hace.
IMPEACHMENT COMO JOGO DURO CONSTITUCIONAL: DA RESPONSABILIZAÇÃO À REMOÇÃO DE GOVERNANTES INDESEJÁVEIS
Authors: Kreuz Leticia
Published: May 2023

O presente artigo objetiva retratar o uso político do instituto do impeachment a partir do conceito de jogo duro constitucional (constitutional hardball). A terminologia remete ao tangenciamento entre práticas lícitas e ilícitas cuja finalidade é disfarçar fins inconstitucionais a partir do uso de instrumentos previstos pela lei, ocultando seu potencial lesivo à estabilidade da democracia e das instituições políticas. A pesquisa utiliza método exploratório, abordando bibliografia e elementos do processo de impeachment contra Dilma Rousseff. O artigo está estruturado em três partes: a necessidade de fiscalização no Estado Democrático de Direito e de equilíbrio entre os poderes, retratando o impeachment como mecanismo deste controle que pode ser usado de forma abusiva; os contornos do processo de impeachment contra Dilma Rousseff e a disputa de narrativa quanto à adequação do mecanismo adotado, entre a legalidade e o “golpe brando”; por fim, a utilização do conceito de jogo duro constitucional como alternativa capaz de explicar o uso político de instrumento jurídico-político que leva à destituição de mandatos eletivos. Conclui-se que, a despeito da previsão legal do impeachment e da observância de garantias processuais, Dilma Rousseff foi destituída do mandato por razões políticas, o que configura a prática de jogo duro constitucional. A estabilidade do sistema político democrático depende da superação do uso do impeachment como arma política.

A very early soybean variety Zabava was selected from the hybrid combination F4 Slavia × EU Mentor by traits of increased cold resistance, drought resistance and reduced reaction for the length of the day. The Zabava variety belongs to a very early group of maturity, at the latitude of Krasnodar (45°) it matures in 94 days, and in yield is not inferior to the Puma standard variety. At the latitude of Samara (53°), it matures in 95 days, and the yield significantly exceeds the Samer 3 standard variety. In 2022, in a competitive variety test in the Krasnodar region, its yield was 2.51 t/ha; in a competitive test in the Samara region, it was 3.33 t/ha. The height of the plants of the Zabava variety at the latitude of Krasnodar averaged 74 cm. In the Samara region, at latitude 53°, the height of plants of the Zabava variety increased slightly to 87 cm. High resistance to low air and soil temperatures in the germination phase, and increased yield in long-day conditions characterizes the new soybean variety Zabava. This allows it to be cultivated in soybean-producing farms in the Central Chernozem, North Caucasus, Middle Volga, Low Volga, Ural, Western Siberian and Eastern Siberian regions of the Russian Federation.

The article presents the results of a comprehensive assessment of 150 soybean cultivars of various ecological and geographical origins from a collection nursery, obtained in 2021 and 2022 on the basis of the breeding station of the S.Seifullin KATU in the conditions of the dry-steppe zone of Northern Kazakhstan. The years of research were characterized as acutely arid. For the conditions of the sharply continental climate of Northern Kazakhstan, the main limiting factor for soybean is precocity. As a result of the research, a promising soybean breeding material with a set of specified characteristics was identified in order to use them in the further breeding process: 104 cultivars with a short growing season; 38 – with the largest number of beans. The highest positive correlation was established between the yield and the number of beans per plant (r = 0.58), the height of attachment of the lower bean (r = 0.40), the number of productive nodes (r = 0.58), the number of seeds in the bean (r = 0.55), the weight of 1000 seeds (r = 0.56) and the weight of seeds per a bean (r = 0.45). A number of soybean cultivars with a relatively high yield, seed quality and precocity have been identified. The yield of the studied soybean cultivars varied from 3.6 to 11.2 quintal/ha (standard – 9.0 quintal/ha). On average, for two years, the highest yield (from 9.1 to 10.1 quintal/ha) was formed by Chinese cultivars: LongKen 310, Beidou 43, Heihe 43, Huajiong 2. The standard cultivar Ivushka was characterized with the highest protein and oil contents in the experiment – 41.06 and 19.03%, respectively.
Development of DNA-markers of a trait of sunflower resistance to a broomrape (Orobanche cumana Wallr.) race G

Broomrape (Orobanche cumana Wallr.) is an obligatory parasite which is able to decrease significantly sunflower yields. The race G is the most spread and virulence broomrape race in the Russian Federation. Cultivation of genetically resistance sunflower varieties and hybrids is the most ecologic and economically efficient method to control this parasite plant. Usage of DNA-markers when selecting the resistant plants increases significantly the effectiveness of a breeding process. To mark the sunflower resistance to broomrape race G, using bioinformative approaches, we developed new DNA-markers: four SCAR (sequence characterized amplified region) and ten SSR (simple sequence repeat). These markers were tested on 20 lines and hybrids of sunflower. Due to the results of this testing, all SSR- and two SCAR-markers were eliminated by steps. SCAR-marker RORS1 was characterized with the presence of an amplified DNA fragment with a length ≈ 168 bps and showed association with a trait of resistance, and SORS1 with a fragment length ≈ 322 bps had a relation with a sus-ceptible phenotype. These markers composed a marker system for a multiplex PCR, which allowed distinguishing resistant and susceptible lines and hybrids, except a line VK678 and F1 hybrids developed using this line as parental one. To eliminate faults of the marker system, seven SCAR-markers analogous to SORS1 were created. Due to estimation result, we selected a marker SORS9 characterized with the presence an amplified DNA fragment with a length ≈ 217 bps in susceptible phenotypes. The new system of markers RORS1/SORS9 for a multiplex PCR was validated on 70 sunflower lines and hybrids. The susceptible lines and hybrids were characterized with amplification of only marker SORS9, resistant lines – only marker RORS1, and resistant hybrids – both markers. The developed marker system allowed distinguishing all susceptible lines and hybrids from the resistant sunflower genotypes.

Supplying of the pharmaceutical industry with medicinal raw materials is carried out mainly due to it cultivation on an industrial scale. For three years (2020–2022), in the conditions of the Krasnodar region in the fields of the North Caucasian branch of VILAR there were studied the ways of hormonal regulation of the formation of seed productivity of essential oil crops – two varieties of Matricaria chamomilla and Salvia officinalis. The results of the conducted research showed that the treatment of plants in the budding phase with growth regulators Zircon (0.04 l/ha) and Gibbersib (0.03 kg/ha) led to a more friend-ly flowering of plants and, accordingly, to an increase in the yield of Matricaria seeds by 15–28 % and Sal-via by 20–28 %. At the same time, their quality im-proves – the weight of 1000 seeds increase by 6–14 %. The use of these growth regulators contributes to increasing the resistance of the studied medicinal crops to dry weather conditions and ensures a reduction in seed yield losses up to 12–26 %, while in the control it was till 22–33 %. With the complex application of Lignohumat (0.05 l/ha) in the initial growth phases of the abovementioned crops and growth regulators (Zircon and Gibbersib) in the budding phase, an increase in seed yield is observed, both in comparison with the control and with some regulators. The highest efficiency was noted in the Lignohumat + Zircon variant, where the seed yield exceeded the control by 28–39 % and in the variant with Zircon – by 9–13 %.

The article provides an overview of sources reflecting the motivation of the agricultural sector of the Russian Federation for the breeding and cultivation of oilseed flax. Special attention is paid to the nutritional value of the discussed agricultural crop. Oil flax seeds are famous for their polyfunctionality, which is explained by the rich diversity of nutrients. The average component composition of the seed is 20% proteins, 41% fats, 27% fiber, 3% vitamins, minerals, phenolic compounds, etc. The amino acid profile of flax protein is characterized by balance and is identical in composition to soybean one – the accepted "ideal" in the circle of plant crops. Flaxseed oil is known for its high content of essential ω-3 and ω-6 polyunsaturated fatty acids, with the predominant amount of the former. The use of flax seed oil can be recommended for the prevention of a wide range of diseases, includ-ing cardiovascular. The biological significance of dietary fibers of oil flax seeds, their soluble (mucus) and insoluble (cellulose, lignins) fractions is shown. The data on the diversity of the vitamin and mineral complex of oil flax seeds are presented, the functions of the corresponding nutritional components are described. The conducted analytical review indicates the prospects for further development of the oil flax industry in order to obtain oil seeds – products with high nutritional value.

The article presents information on the results of long-term effective work in the Federal Center of Agriculture Research of the South-East Region on sunflower breeding in the Saratov region. The main task facing breeders was to develop productive, precocious sunflower varieties resistant to local races of broomrape and sunflower moth. An invaluable contribution to the development of sunflower breeding was made by outstanding Russian breeders Plachek E.M., Zhdanov L.A., Morozov V.K., Pustovoit V.S., Pimakhin V.F., and others. They bred new highly productive sunflower varieties, being the main source for the production of edible oil that are widely distributed in the Volga region, Central Black Earth regions, Siberia and the Urals. For the first time, Saratov scientists conducted research in the field of heterosis breeding. They formed a large working collection of sunflowers, a genetic collection of marker traits, identified promising forms for subsequent stages of the breeding process, and developed a variety of initial material in the conditions of Saratov. The main focus is on developing almost isogenic lines, studying the genetic control of marker traits, determining the effects of the influence of genes on economically useful traits. Studies on the private genetics of sunflower have been carried out. Based on experimental data, ornamental sunflower varieties with flowers of various colors – Oreol, Raduga, and Solnechny salut were developed. For 2022, the State Register of Breeding Achievements of the Russian Federation includes the following varieties bred in the Federal Center of Agriculture Research of the South-East Region: Saratov 82, Saratov 85, Skoropely, Skoropely 87, Stepnoy 81, Lyubim-chik, Saratov 20, Slastena and hybrids: Agrotex, Continent, Yubileyny 75, Everest, YuVS 2, YuVS 3, YuVS 4, YuVS 5, YuVS 7.

Salah satu fatwa Saidina Umar bin Khattab yang menarik untuk dikaji adalah tentang ghanimah. Ijtihad yang dilakukan oleh Saidina Umar, yakni tidak membagi tanah hasil ghanimah pada masanya dan memerintahkan tanah hasil ghanimah untuk tetap dibiarkan pada pemilik dan pengelolanya. Fatwa ini ditolak oleh Abdurrahman bin Auf dan sahabat lainnya, dengan alasan tidak pernah dilakukan oleh Nabi Muhammad SAW. Fatwa yang dilakukan Saidina Umar tentunya bukan tanpa alasan, sebab Umar merupakan Khalifah yang cerdas dan arif. Untuk itu paper ini akan menguraikan fatwa tersebut menjadi sebuah pemikiran ekonomi Islam yang lebih utuh. Dalam mengurai problematika yang ada, peneliti menggunakan penelitian kualitatif deskriptif dengan sumber data sekunder. Hasil penelitian ini menyimpulkan bahwa kebijakan Umar adalah kebijakan yang tepat, sebab yang berhak mengatur ghanimah adalah Amirul Mukminin, yakni di masa itu adalah Saidina Umar bin Khattab. Saidina Umar telah membuat sebuah fondasi yang kokoh, baik filosofi, kadar pungutan, maupun jenis-jenis harta yang dipungut pajaknya.
Modelling the effects of E/Z photoisomerization of a cyclocurcumin analogue on the properties of cellular lipid membranes

Published: May 2023

The use of photosensitive molecules capable of isomerizing under light stimuli, and thus induce perturbation in biological systems, is becoming increasingly popular for potential light-activated chemotherapeutic purposes. We recently show that a cyclocurcumin derivative (CCBu), may be suitable for light-activated chemotherapy and may constitute a valuable alternative to traditional photodynamic therapy, due to its oxygen-independent mechanism of action, which allows the treatment of hypoxic solid tumors. In particular, we have shown that the E/Z photoisomerization of CCBu correlates with strong perturbations of model lipid bilayers1. In this work, we perform all-atom classical molecular dynamics for a more complex bilayer, whose composition is, thus, much closer to eukaryotic outer cell membranes. We have evidenced important differences in the interaction pathway between CCBu and the complex lipid bilayer as compared to previous models, concerning both the membrane penetration capacity and the isomerization-induced perturbations. While, we confirm that structural perturbations of the lipid membrane are induced by isomerization, we also show how the use of a simplified membrane model can result in an oversimplification of the system and hinders key physical and biological phenomena. Although, CCBu derivative may be considered as suitable candidate for light-activated chemotherapy, we also underline how the inclusion of bulkier substituents, inducing larger perturbations upon photoisomerization, may enhanced its efficiency.

Imaging and quantification of stained blood cells are important for identifying the cells in hematology and for diagnosing diseased cells or parasites in cytopathology. Romanowsky staining have been used traditionally to produce hues in blood cells using anionic eosin Y and cationic methylene blue. While Romanowsky stains have been widely used in cytopathology, end-users have experienced problems with varying results in staining due to premature precipitation or evaporation of methanol, leading to the inherent inconsistency of solution-based Romanowsky staining. Here, we demonstrate that staining and destaining of blood smear are controllable by the contact time of agarose gel stamps. While the extent of staining and destaining are discernable by hue values of stamped red blood cells in micrographs, quantification of adsorbed and desorbed Romanowsky dye molecules (in particular, eosin Y, methylene blue, and azure B) from and to the agarose gel stamps needs a model that can explain the sorption process. We find predictable sorption of the Romanowsky dye molecules from the pseudo-second-order kinetics models for adsorption and the one phase decay model for desorption. Thus, the method of agarose gel stamping demonstrated here could be an alternative to solution-based Romanowsky staining with predictable quantity of sorption and timing of contact.

The exponential decay of light intensity in absorbing media poses a particular challenge to the development of light-driven chemical reactions on an industrial scale. To counteract the challenges of the irradiation field, photoreactors are required to enable accelerated mass transport on both the laboratory and production scale. This contribution presents the development of a modular mini-plant photoreactor (MISCOP) designed to bridge the gap between small laboratory and industrial scale photoreactors. To improve the overall efficiency of the photoreactor, the acceleration of mass transport along the direction of light propagation through static mixers is experimentally and numerically investigated by exploiting the modularity of the photoreactor. The results reveal a significant narrowing of the residence time distribution as well as enhanced mass transport along the ray trajectory.
Selective Electroreduction of Nitrate into Ammonia on CuCoAl Layered Double Hydroxide for Sustainable Resourcification

Published: May 2023

One-step nitrate electroreduction (NO3RR) is a promising strategy to generate ammonia in a straightforward and environmentally friendly manner. However, most catalysts suffer from limited electrocatalytic activity as well as poor selectivity. In this work, a tunable trimetallic CuCoAl layered double hydroxide (LDH) catalyst was designed to generate ammonia exclusively and efficiently with an onset potential at 0.13 V vs. RHE. The synergy among Cu, Co, and Al bestowed a 99.5 % Faradaic efficiency (FE) for ammonia with a yield rate of 0.22 mol h-1 g-1, rivaling the performance of state-of-the-art non-precious metal NO3RR electrocatalysts. Control materials were employed to elucidate the roles of Cu, Co, and Al toward lowering the overpotential and suppressing the formation of nitrite byproduct. DFT calculations were performed to further investigate the adsorption strength of anionic adducts and electrolytes on LDH surface to unravel the effects of buffer conditions on NO3RR performance. The scalable nature of our earth-abundant catalysts is particularly attractive due to the intrinsic low costs of the raw materials. We envision that this precious-metal-free catalyst can be generally applicable to other resourcification processes to achieve a future sustainable society.

Polycyclic aromatic sulfur heterocycles are environmental pollutants formed from incomplete combustion processes and crude oil spills. Their excited state dynamics are not understood. Herein, femtosecond transient absorption is combined with steady-state spectroscopy and computational methods to elucidate the relaxation mechanisms of three dibenzothiophene derivatives. The low-energy singlet and triplet states all have pipi* character in the Franck-Condon region and two minima were located in the S1 surface. Excitation at 320 nm populates their S1 state directly, which relaxes with lifetimes ranging from 4 to 13 ps. Most of the S1 population undergoes efficient intersystem crossing to the triplet state with lifetimes ranging from 820 ± 50 to 900 ± 30 ps. The compounds exhibit negligible nonradiative internal conversion, low fluorescence yields of 1.2 to 1.6%, and triplet yields of ca. 98%. Linear interpolation of internal coordinates reveals the chemical basis for relaxing the spin-forbidden intersystem crossing in these pi-aromatic systems.

Published: May 2023

A catalyst selection method for the optimization of an asymmetric, vinylogous Mukaiyama aldol reaction is described. A large library of commercially available and synthetically accessible copper-bis(oxazoline) catalysts was constructed in silico. Conformer-dependent, grid-based descriptors were calculated for each catalyst, defining a chemical feature space suitable for machine learning. Selection of a diverse subset of catalyst space produced an initial training set of 26 novel bis(oxazoline) ligands which were synthesized and tested for stereoselectivity in the copper-catalyzed, vinylogous Mukaiyama aldol reaction for five substrate combinations. One ligand in the training set provided 88% average enantiomeric excess, exceeding the performance of catalysts identified through an initial optimization campaign. Supervised and semi-supervised catalyst selection methods, including quantitative structure-selectivity relationship modelling, nearest neighbors analysis, and a focused analogue clustering strategy, were employed to identify an additional 12 novel bis(oxazoline) ligands. The selected ligands outperformed the initial training set hit in four out of five product classes, and in some cases demonstrated excellent enantiocontrol exceeding 95% ee. The effectiveness of the unsupervised training set selection process is discussed, and the expediency of the nearest neighbor and focused analogue approaches are contrasted with the supervised quantitative structure-selectivity relationship modelling approach.

Published: May 2023

The objective of this article is to explore the communities generated on YouTube by content creators on complementary and alternative medicine (CAM). Through graph theory, visual network analysis and a broad overview of the content of selected channels, communities are examined to assess their strength as a community in terms of their degree of connectedness and density. Strong communities are composed of individuals who spread the word about the same topic and viewpoint, acting as one block. Results showed that content creators who promote CAM on YouTube have small and weak communities; in contrast, content creators related to scientific dissemination, who are against CAM, have built strong communities.

Published: May 2023

The present study explores the knowledge and perceptions that 72 Chilean EFL (English as a foreign language) pre-service teachers have regarding the effect of video games in their daily and academic routine in terms of foreign language learning. By applying a 5-point Likert scale, it was possible to gather data concerning their sociodemographic characteristics and their views in relation to five dimensions: (1) Generalexperience with video games, (2) general preferences about video games, (3) strengths and weaknesses of video games, (4) video games as a learning experience, and (5) video games and the four language skills. Once the data were collected, the Spearman’s orrelation coefficient was used with the purpose of determining the relationships among the respondents’ answers. The results indicated that the four language skills, especially the receptive skills, can be practiced while playing video games. Also, digital games allowed the participants to teach and learn from other players through gameplay. This process was followed by a hierarchical cluster analysis that allocated the respondents into four groups based on the similarities of their responses.

Lecciones de la derrota: análisis de dos newsgames de Argentina
Authors: Mancuso Mariano , Maté Diego
Published: May 2023

A comienzos del nuevo milenio, el videojuego empezó a trazar vínculos con otras esferas de la cultura como el arte, la publicidad, la política, el activismo, entre otros. El cruce con el periodismo dio lugar al newsgame, una forma videolúdica que funciona de acuerdo con las previsibilidades del campo de la información como la tematización de hechos de actualidad y la construcción de agenda. El cambio de funcionamiento genera transformaciones, por ejemplo, el fracaso, en vez de constituir un disvalor, habilita distintas vías de problematización de hechos noticiosos. En este trabajo se analizan dos newsgames del estudio argentino Shitty Games. Invocando elementos de la historia del videojuego, sobre todo del periodo 8 bits, pero operando dentro del campo del periodismo, Decretator (2016) y Suicid.ar (2015) refieren a dos hechos de la actualidad reciente argentina y la editorializan vehiculizando estrategias de persuasión propias de los géneros argumentativos del periodismo (como el editorial o la columna de opinión), los cuales habilitan un espacio polémico que invita a tomar posición sobre los despidos estatales realizados por el gobierno de Mauricio Macri y sobre el tratamiento que distintos medios hicieron de la muerte del fiscal Alberto Nisman.

FEATURES OF SETTING TARIFFS FOR THE TRANSPORTATION OF PASSENGERS ON BUS ROUTES GENERAL USE
Authors: Nepran Andrey , Petryk Alina
Published: May 2023

Determining an economically justified tariff for the transportation of passengers in road transport is of great importance, since the level of the tariff largely depends on the income and profit of motor transport and tourist enterprises. The article examines the peculiarities of setting tariffs for passenger transportation by road transport. The justification and calculation of the tariff for the transportation of passengers by public road transport was carried out.
In Ukraine, state regulation of fares for the transportation of passengers on suburban and intercity intra-regional public bus routes has been abolished, i.e. fares for such routes are free. Tariffs for the transportation of passengers by road transport were established based on the cost method of pricing. The transportation tariff was determined based on the planned expenses for the transportation of passengers, taxes and fees, as well as taking into account the economically justified profit of the carrier. The cost of transporting passengers by road has been calculated in accordance with the current regulatory framework. The value of the transport tariff was calculated, taking into account all component costs.
The planning and calculation of the costs of the motor vehicle enterprise was carried out on the basis of the normative method, taking into account the industry standards for the use of material and fuel and energy resources, the rates of taxes and fees (mandatory payments), the forecast price index of manufacturers of industrial products for the planned year. The calculated amount of the tariff will allow the enterprise to ensure the profitability of passenger transportation and competitiveness in the market.
