In 2017–2020, we studied the yield formation, its structure and quality in early-maturing self-pollinated lines – maternal forms of sunflower hybrids VK 101, VK 678, VK 905, VA 760, and ED 765 bred at V.S. Pustovoit All-Russian Research Institute of Oil Crops. The research was carried out on leached chernozem in the central natural and climatic zone of the Kras-nodar region under free flowering cultivation with plant population of 40, 50, 60, and 70 thousand plants/ha. We established the negative dependence of seed yield from the sieve with oblong holes of 2.5 × 20 mm in size on increasing the plant density. The maximum yield of this seed fraction was obtained when growing maternal lines VK 101 and ED 765 with a population of 50 thousand plants/ha (1.18 and 1.12 t/ha), VA 760 and VK 678 – 60 thousand plants/ha (1.16 and 1.33 t/ha), VK 905 – 70 thousand plants/ha (1.50 t/ha). With the thickening of sowings of maternal lines by 10 thousand plants/ha, the yield of seeds from the sieve with a hole size of 2.5 × 20 mm on average decrease in VK 905 by 1.9%, VK 101, VK 678, and VA 760 – by 4.9–5.0%, and ED 765 – by 5.9%. With increasing the plant population from 40 to 70 thousand plants/ha, the oil content of seeds increased from 0.6% for VK 101 to 3.0% for VK 678, and on average for the maternal lines of hybrids – by 1.7%. We established the negative dependence of the head diameter, size of productive area of a head, thousand-seed weight, and num-ber of filled seeds in a head on increase in the plant density. The increase of plant population by 10 thou-sand plants/ha resulted in decrease of a head diameter by 0.64–1.02 cm, productive area of a head by 14.4–27.2 cm2, thousand-seed weight by 1.4–3.5 g, a number of filled seeds in a head by 37–125 seeds, depending on the maternal line of a hybrid.

The article assesses and analyzes the factors influencing the formation of a system for monitoring the activities of business structure. We used an expert study, which allowed us to determine the factors that form the systems for monitoring the activities of business structures, and later assessed their relative importance. To take into account the factors influencing the formation of a system for monitoring the activities of business structures, cluster analysis was applied, and the isomorphic and isotonic similarity of a set of highlighted factors was used. The average scores assigned by experts for each factor are determined. Direct and indirect connections between the factors and between the clusters themselves have been identified. Specifications are used for this of KLAST_IZOMORF_TREK and KLAST_IZOTON_TREK for Microsoft Office Excel. An integrated model of relationships between the factors influencing the formation of a system for monitoring the activities of business structures, which are linearly and indirectly related to each other, has been built. The classification of factors influencing the formation of a system for monitoring the activities of business structures has been carried out. The proposed classification can be practically applied by the heads of business structures when analyzing the quality of monitoring and making corrective decisions on the selection of types of information and sources of their receipt, monitoring methods, as well as the selection of personnel responsible for monitoring. A mechanism is proposed for a set of measures aimed at using reserves to improve the quality of monitoring the activities of a business structure. It is proved that the introduction of a set of measures aimed at using reserves to improve the quality of monitoring the activities of business structures would allow the monitoring system to focus the analytical potential of managers on problematic aspects of the development of a business structure, the causes of which lie in their external environment. It is necessary to achieve such quality of monitoring, in which the nature of the action of the selected factors on the object under study is positive by default.

Published: June 2022

Ultrahigh-resolution Fourier transform mass spectrometry (FTMS) has revealed unprecedented detail of natural complex mixtures such as dissolved organic matter (DOM) on a molecular formula level, but we lack approaches to access the underlying structural complexity. We here explore the hypothesis that every DOM precursor ion is potentially linked with all emerging product ions in FTMS2 experiments. The resulting mass difference (Δm) matrix is deconvoluted to isolate individual precursor ion Δm profiles and matched with structural information, which was derived from 42 Δm features from 14 in-house reference compounds and a global set of 11477 Δm features with assigned structure specificities, using a dataset of ~18000 unique structures. We show that Δm matching is highly sensitive in predicting potential precursor ion identities in terms of molecular and structural composition. Additionally, the approach identified unresolved precursor ions and missing elements in molecular formula annotation (P, Cl, F). Our study provides first results how Δm matching refines structural annotations in Van Krevelen space, but simultaneously demonstrates the wide overlap between potential structural classes. We show that this effect is likely driven by chemodiversity and offers an explanation for the observed ubiquitous presence of molecules in the center of the Van Krevelen space. Our promising first results suggest that Δm matching can both unfold the structural information encrypted in DOM and assess the quality of FTMS-derived molecular formulas of complex mixtures in general.
TMAO: Protecting Proteins from Feeling the Heat

Published: June 2022

Osmolytes are ubiquitous in the cell and play an important role in controlling protein stability under stress. The natural osmolyte trimethylamine N-oxide (TMAO) is used by marine animals to counteract the effect of pressure denaturation at large depths. The molecular mechanism of TMAO stabilization against pressure and urea denaturation has been extensively studied, but unlike the case of other osmolytes the ability of TMAO to protect proteins from high temperature has not been quantified. To reveal the effect of TMAO on folded and unfolded protein ensembles and the hydration shell at different temperatures, we study a mutant of the well-characterized, fast-folding model protein B (PRB). We carried out >190 µs in total all-atom simulations of thermal folding/unfolding of PRB at multiple temperatures and concentrations of TMAO. The simulations show increased thermal stability of PRB in presence of TMAO. Partly structured, compact ensembles are favored over the unfolded state. TMAO forms two shells near the protein: an outer shell away from the protein surface alters hydrogen bond lifetimes of water molecules and increases hydration of the protein to help stabilize it; a less-populated inner shell with opposite TMAO orientation closer to the protein surface binds exclusively to basic side chains. The cooperative co-solute effect of the inner and outer shell TMAO has a small number of TMAO molecules ‘herding’ water molecules into two hydration shells at or near the protein surface. The stabilizing effect of TMAO on our protein saturates at 1 M despite higher TMAO solubility, so there may be little evolutionary pressure for extremophiles to produce higher intracellular TMAO concentrations if true in general.

Published: June 2022

Consisting of more than 350 isolated members, the Daphniphyllum alkaloids possess complicated, polycyclic, and often caged skeletons along with diverse, interesting biological profiles. Among this natural product family, the representative calyciphylline A-type subfamily has triggered particular interest from the organic synthesis community. In this paper, we wish to report divergent total syntheses of three calyciphylline A-type alkaloids, namely (−)-10-deoxydaphnipaxianine A, (+)-daphlongamine E, and (+)-calyciphylline R. Our work highlights an efficient, divergent strategy via late-stage diallylic alcohol rearrangements, including an unprecedented oxidative Nazarov electrocyclization using an unfunctionalized diallylic alcohol and, an unusual, transannular allylic alcohol rearrangement. Other key transformations in our approach including an nitrile hydration using a highly efficient “donor-acceptor” platinum catalyst, an intramolecular Heck coupling and an intramolecular, regioselective pinacol coupling. Moreover, the power of selective amide reductions has also been showcased by novel and classic tactics. The strategies and methods used in our approach might provide further inspiration for natural product synthesis. Particularly, the novel oxidative Nazarov electrocyclization should be valuable in the chemical synthesis of other cyclopentenone-containing small molecules.
Tuning Selectivity in the Direct Conversion of Methane to Methanol: Bimetallic Synergistic Effects on the Cleavage of C-H and O-H Bonds over NiCu/CeO2 Catalysts
Authors: Lustemberg Pablo G. , Senanayake Sanjaya D. , Rodriguez José A. , Ganduglia-Pirovano M. Verónica
Published: June 2022

The efficient activation of methane and simultaneous water dissociation are crucial in many catalytic reactions on oxide-supported transition metal catalysts. On very low-loaded Ni/CeO2 surfaces, methane easily fully decomposes, CH4 -> C + 4H, and water dissociates, H2O-> OH + H. However, in important reactions such as the direct oxidation of methane to methanol (MTM), where complex interplay exists between reactants (CH4, O2), it is desirable to avoid the complete dehydrogenation of methane to carbon. Remarkably, the barrier for the activation of CH bonds in CHx (x= 1-3) species on Ni/CeO2 surfaces can be manipulated by adding Cu, forming bimetallic NiCu clusters, whereas the ease for cleavage of OH bonds in water, is not affected by ensemble effects, as obtained from density functional theory-based calculations. CH4 activation occurs only on Ni sites and H2O activation on both Ni and Cu sites. The MTM reaction pathway for the example of the Ni3Cu1/CeO2 model catalyst predict higher selectivity and a lower activation barrier for methanol production, compared with that for Ni4-CeO2. These findings point toward a possible strategy to design active and stable catalysts which can be employed for methane activation and conversions.

Intracellular pathogens lose many metabolic genes during their evolution from free-living bacteria, but the pathogenic consequences of their altered metabolic programs on host immunity are poorly understood. Here, we show that a pathogenic strain of Francisella tularensis subsp. tularensis (FT) has five amino acid substitutions in RibD, a converting enzyme of the riboflavin synthetic pathway responsible for generating metabolites recognized by mucosal-associated invariant T (MAIT) cells. Metabolites from a free-living strain, F. tularensis subsp. novicida (FN), activated MAIT cells in a T-cell receptor (TCR)–dependent manner, whereas introduction of FT-type ribD to the free-living strain was sufficient to attenuate this activation in both human and mouse MAIT cells. Intranasal infection in mice showed that the ribDFT-expressing FN strain induced impaired Th1-type MAIT cell expansion and resulted in reduced bacterial clearance and worsened survival compared with the wild-type free-living strain FN. These results demonstrate that F. tularensis can acquire immune evasion capacity by alteration of metabolic programs during evolution.

Published: June 2022

A low
physical fitness and incorrect technique could result in muscle strength
imbalance and poor dynamic/static balance in handball players. This study aimed
to evaluate the muscular and functional performance of lower limbs in young
handball athletes. Twelve female handball athletes performed isokinetic tests
at 60°/s, 120°/s, 180°/s, and 240°/s for the knee’s extensor and flexor muscles
and functional tests for lower limbs. There were no differences between the
limbs in the knee’s muscles’ peak torque, while the values of the conventional
ratio were below the recommended. In functional tests, no significant changes
were observed. Nevertheless, the composite score of the Y-Balance test
demonstrated values below the suggested. Overall, the results showed that
female youth handball athletes had symmetry between the limbs; however, there
was a tendency to muscle imbalance (hamstrings weaker than quadriceps), and
dynamic balance deficits that might increase the risk of musculoskeletal
injury.

Published: June 2022

Objetivo.

Sintetizar os achados sobre correlatos da atividade física (AF) e do comportamento sedentário (CS) em crianças sul-americanas.

Método.

Realizou-se uma busca dos artigos no período de 24 de junho até 27 de outubro de 2020, nas bases de dados LILACS, PubMed, SciELO, Scopus e Web of Science. Para ampliar a busca, foram examinadas as referências dos artigos de revisão identificados e realizada uma consulta a um painel de especialistas. Foram incluídos estudos com delineamentos observacional e de intervenção com foco em crianças sul-americanas de zero a 5 anos de idade.

Resultados.

Dos 3 111 artigos inicialmente identificados, 18 foram elegíveis: 14 com delineamento observacional, 12 realizados no Brasil e 17 conduzidos com pré-escolares (3 a 5 anos de idade). Além do Brasil, os únicos países representados foram o Chile e o Equador. A AF e o CS foram medidos por acelerômetros em sete estudos, porém houve alta variabilidade nos instrumentos e pontos de corte usados. Embora as crianças tenham sido consideradas fisicamente ativas em 12 estudos, seis estudos mostraram que elas despendiam muito tempo em CS. Os domínios de influência mais avaliados foram o individual (14 estudos) e o interpessoal (11 estudos), seguidos pelo ambiental (oito estudos) e o político (um estudo). As intervenções no contexto escolar (quatro estudos) aumentaram os níveis de AF e diminuíram o tempo em CS. Entretanto, as evidências dos estudos transversais e de intervenção apresentaram alto risco de viés.

Conclusão.

Diante das lacunas identificadas, recomendam-se estudos com delineamentos robustos que incluam mais países sul-americanos, com foco em bebês e crianças com menos de 3 anos de idade e que investiguem correlatos dos domínios ambiental e político.

Authors: Saengrith Waristha , Viriyavejakul Chantana , Pimdee Paitoon
Published: June 2022

Problem-solving skill is one of the soft skills that has become essential for employees in various organizations. Training model and educational technology were considered key success factors in delivering knowledge for personnel in the workplace to develop this skill. Problem-Based Learning (PBL) is a key driver for learning activities, which has been increasingly adopted for workplace training and has proven to be one of the best approaches to helping learners improve their problem-solving skills in the organization. Hence, this research aims to synthesize problem-based blended training via chatbot to enhance problem-solving skills in the workplace. Literature review, document analysis, and focus group technique were used as the main procedures for the first phase of model synthesis. The effectiveness of the training model was examined in the second phase by applying it to 20 employees of the flexible lamination manufacturers in Thailand from purposive sampling. The training was held for four weeks and examined with a problem-solving skill test. In addition, a follow-up test has been conducted to monitor retention skills after a four-week training period. Data analysis used the repeated-measures ANOVA test with normality and homogeneity as a prerequisite test. This study shows that the problem-based blended training model via chatbot to enhance problem-solving skills in the workplace comprises six main steps: (1) Group identification; (2) Problem identification; (3) Idea creation; (4) Learning; (5) Implementation; (6) Evaluation. The results on the implemented training model showed that problem-solving skills after training were significantly higher than those before training, and the retention of skill remained higher than that before training and did not significantly change after finishing training at a statistical significance of 0.5. As a result, the developed model is highly appropriate for implementation, particularly because the chatbot platform is involved in almost every step of this training model to accommodate learners who can easily access the training platform, repeat the training content, and feel motivated to explore new information to improve their problem-solving skills. In a post-COVID-19 period with distancing required in the workplace, this model is applicable to deliver efficiency in workplace training. Doi: 10.28991/ESJ-2022-SIED-01 Full Text: PDF

El hombre en busca de sentido
Authors: Figueroa Velázquez Juan Gabriel , Cerón Islas Arlen
Published: June 2022

En su obra, el doctor Viktor E. Frankl, narra la experiencia de ser prisionero en los campos de concentración en Polonia y Alemania, durante la Segunda Guerra Mundial. Básicamente estructura su narración de acuerdo con cuatro etapas: el internamiento, la vida en el campo, la liberación y finalmente hace una revisión de los conceptos básicos de la logoterapia, una rama del psicoanálisis que él formuló. Resalta en su narración las formas o estrategias, físicas y mentales que los prisioneros tenían que implementar a fin de sobrevivir cada día, resistiendo a los castigos y horrores a los que fueron sometidos, la cual consistía básicamente en aceptar su sufrimiento, y estaban convencidos de que su vida, su existencia aún tenía un propósito que deberían de cumplir, y si para ello era necesario resistir tanto sufrimiento, entonces estaban dispuesto a aceptarlo. Esta idea permitió que muchos prisioneros obtuvieran una fuerza física, pero sobre todo mental y espiritual para poder soportarlo hasta el final del Holocausto.

Published: June 2022

La Universidad Tecnológica de Tula–Tepeji tiene el compromiso de fortalecer la cobertura educativa mediante una modalidad acorde con las necesidades de la sociedad. El modelo de sistema mixto–virtual (MMV), pensado en formar a personas que laboran en horarios integrales y que no pueden dedicarse a la educación superior de tiempo completo, es innovador en la región, en el estado de Hidalgo, así como en el propio Subsistema de Universidades Tecnológicas y Politécnicas(SUT), surge antes de la actual contingencia; por lo que, adquiere mayor relevancia. El MMV tiene como base la factibilidad y pertinencia del proyecto, un diseño instruccional apropiado, indicadores de calidad definidos por los Comité Interinstitucionales para la Evaluación de la Educación Superior (CIEES) y es completamente replicable. Se aplicó en los programas educativos de Técnico Superior Universitario y la Licenciatura en Ingeniería, posteriormente posgrado y educación continua.
Pan campesino a base de masa madre
Authors: Barranco Angeles Elsa Nathalie , Gómez García Norma
Published: June 2022

El pan es un alimento hecho con harina, agua, sal entre otros ingredientes dependiendo del tipo de pan, en su elaboración pasa por un amasado, fermentación, y su cocción es en horno.

La fermentación, es la clave del sabor y características del pan, se atribuye que los precursores de la fermentación fueron los egipcios, cuando elaboraban un tipo de tortillas de mijo y cebada, cocidas en piedras calentada y al parecer, al dejar un pedazo de masa sin cocción notaron que se transformó a una masa agria, que ahora se conoce como masa madre.

Published: June 2022

Introducción: La caries de la infancia temprana CIT, según el criterio obtenido en este trabajo de revisión bibliográfica, y su relación con la lactancia materna (LM), ha sido un tema muy debatido entre diversos autores, inclusive, los resultados de gran número de estudios han apuntado a conclusiones que pudieran considerarse contradictorias entre sí, como es el factor protector de la LM en la prevención del desarrollo de CIT (ECC, por sus siglas en inglés). Tener presente el papel que desempeña la LM en el desarrollo de caries dental, a lo largo de la niñez, es importante para contribuir a que los profesionales de salud oral, y padres de los infantes, puedan prevenir la CIT durante el proceso de LM que, como se ha reportado, puede contribuir al desarrollo integral de los pacientes pediátricos. Objetivo: Establecer, en base a revisión bibliográfica, la correlación entre LM y desarrollo de caries dental. Material y Métodos: Revisión bibliográfica Resultados: La leche materna contiene componentes inmunológicos que generan un ambiente desfavorable para el desarrollo de cepas bacterianas en la cavidad bucal, promueve la remineralización de las superficies del esmalte dental, en niños que son amamantados, es menor que en aquellos que no lo son, por lo que se tiene que la LM funciona como factor de protección que minimiza el riesgo de formación de caries dental. Conclusiones: En base a los resultados del trabajo de investigación presente se puede concluir que no hay una correlación positiva entre la LM y el desarrollo de CIT, siendo ambas variables independientes

Published: June 2022

Humans are the true wealth of the nation. It is appropriate if humans become the main goal in development. Then the United Nations Development Program (UNDP) initiated the Human Development Index (HDI) as an indicator in measuring the progress of human development. Indonesia took part in applying the HDI calculation. Increasing the value of HDI from various provinces in Indonesia continues to be carried out, including in the Province of West Nusa Tenggara. Improving human development is based on an increase in all dimensions of the HDI itself. West Nusa Tenggara Province consists of 10 regencies/ cities. With different geographical, social, and economic backgrounds, the achievement of HDI in each region will vary. The purpose of this study was to determine the model of the HDI in West Nusa Tenggara Province in 2010-2017 using a fixed-effect model, which was used to see the influence of dimensions on the HDI and explain the differences in intercepts in each district/ city in West Nusa Tenggara Province. Based on the research conducted, a fixed effect panel data model on HDI was obtained for each district/ city in NTB in 2010-2017. From the HDI model obtained, it is known that the slope coefficient is constant, but the intercept varies throughout the district/ city. The slope coefficient value shows the magnitude of the influence of life expectancy, school duration, the average length of schooling, and expenditure per capita adjusted to the HDI of each district/ city.

Graph theory is one of the topics in mathematics that is quite interesting to study because it is applicable and can be combined with other mathematical topics such as group theory. The combination of graph theory and group theory is that graphs can be used to represent a group. An example of a graph is a power graph. A power graph of the group  is defined as a graph whose vertex set is all elements of  and two distinct vertices  and  are connected if and only if  or for a positive integer x and y. In this study, the author discusses the power graph of the dihedral group  The results obtained from this study are the power graph of the dihedral group  where  with  prime numbers and an  natural number is a graph consisting of two non-disjoint subgraphs, namely complete subgraphs and star subgraphs. And we find that its radius and diameter are 1 and 2.
