A Many-Body, Fully Polarizable Approach to QM/MM Simulations
Authors: Lambros Eleftherios , Lipparini Filippo , Cisneros G. Andres , Lab Paesani
Published: October 2020

We present a new development in quantum mechanics/molecular mechanics (QM/MM) methods by replacing conventional MM models with data-driven many-body (MB) representations rigorously derived from high-level QM calculations. The new QM/MM approach builds on top of mutually polarizable QM/MM schemes developed for polarizable force fields with inducible dipoles and uses permutationally invariant polynomials to effectively account for quantum- mechanical contributions (e.g., exchange-repulsion, and charge transfer and penetration) that are difficult to describe by classical expressions adopted by conventional MM models. Us- ing the many-body MB-pol and MB-DFT potential energy functions for water, which include explicit 2-body and 3-body terms fitted to reproduce the corresponding CCSD(T) and PBE0 2- body and 3-body energies for water, we demonstrate a smooth energetic transition as molecules are transferred between QM and MM regions, without the need of a transition layer. By effectively elevating the accuracy of both the MM region and the QM/MM interface to that of the QM region, the new QM/MB-MM approach achieves an accuracy comparable to that obtained with a fully QM treatment of the entire system.
Cooperative Activation of Cellulose with Natural Calcium
Authors: Facas Gregory G. , Maliekkal Vineet , Zhu Cheng , Neurock Matthew , Dauenhauer Paul
Published: October 2020

Naturally occurring metals such as calcium catalytically activate the inter-monomer β-glycosidic bonds in long chains of cellulose initiating reactions to volatile oxygenates for renewable applications. In this work, the millisecond kinetics of calcium catalyzed reactions were measured via the method of pulse-heated analysis of solid/surface reactions (PHASR) at high temperature (370-430 °C) to reveal accelerated glycosidic ether scission with a second order rate dependence on Ca2+ ions. First principles density functional theory (DFT) calculations were used to identify stable binding configurations for two Ca2+ ions that demonstrated accelerated transglycosylation kinetics with an apparent activation barrier of 50 kcal mol-1 for a cooperative calcium catalyzed cycle. The agreement of mechanism with calcium cooperativity to the experimental barrier (48.7 ± 2.8 kcal mol-1) suggests that calcium enhances reactivity through a dual role of disrupting native H-bonding and stabilizing charged transition states.
Quantifying Uncertainties in Solvation Procedures for Modeling Aqueous Phase Reaction Mechanisms

Published: October 2020

Computational quantum chemistry modeling provides fundamental chemical and physical insights into solvated reaction mechanisms across many areas of chemistry, especially in homogeneous and heterogeneous renewable energy catalysis. Such reactions may depend on explicit interactions with ions and solvent molecules that are non-trivial to characterize. Rigorously modeling explicit solvent effects with molecular dynamics usually brings steep computational costs while the performance of continuum solvent models such as polarizable continuum model (PCM), nonlocal solvent models with charge asymmetry (CANDLE), conductor-like screening model for real solvents (COSMO-RS) and effective screening medium method with the reference interaction site model (ESM-RISM) are less well understood for reaction mechanisms. Here, we revisit a fundamental aqueous phase hydride transfer reaction, carbon dioxide (CO2) reduction by sodium borohydride (NaBH4), as a test case to evaluate how different solvent models perform in aqueous phase charge migrations that would be relevant in general to renewable energy catalysis mechanisms. For this system, quantum mechanics/molecular mechanics (QM/MM) molecular dynamics simulations almost exactly reproduced energy profiles from all-QM simulations, and the Na+ counterion in the QM/MM simulations plays an insignificant role over ensemble averaged trajectories that describe the reaction pathway.However, solvent models used on static calculations gave much more variability in data depending on whether the system was modeled using explicit solvent shells and/or the counter ion. We pinpoint this variability due to unphysical descriptions of charge-separated states in the gas phase (i.e., self-interaction errors), and we show that using more accurate hybrid functionals and/or explicit solvent shells will lessens these errors and allow more reliable results to be obtained.This work closes with recommended procedures for treating solvation in future computational efforts in studying renewable energy catalysis mechanisms.
Complementary Base Lowers the Barrier in SuFEx Click Chemistry for Primary Amine Nucleophiles
Authors: Luy Jan-Niclas , Tonner Ralf
Published: October 2020

The Sulfur (VI) Fluoride Exchange (SuFEx) reaction is an emerging scheme for connecting molecular building blocks. Due to its broad functional group tolerance and rather stable resulting linkage it is seeing rapid adoption in various fields of chemistry. Still, to date the reaction mechanism is poorly understood which hampers further development. Here, we show that the mechanism of the SuFEx reaction for the prototypical example of methanesulfonyl fluoride reacting with methylamine can be understood as an SN2-type reaction. By analyzing the reaction path with the help of density functional theory in vacuo and under consideration of solvent and co-reactant influence we identify the often used complementary base as crucial ingredient to lower the reaction barrier significantly by increasing the nucleophilicity of the primary amine. With the help of energy decomposition analysis (EDA) at the transition state structures we quantify the underlying stereo-electronic effects and propose new avenues for experimental exploration of the potential of SuFEx chemistry.
Why Conventional Design Rules for C–H Activation Fail for Open-Shell Transition-Metal Catalysts
Authors: Nandy Aditya , Kulik Heather
Published: October 2020

The design of selective and active C–H activation catalysts for direct methane-to-methanol conversion is challenging. Bioinspired complexes that form high valent metal-oxo intermediates capable of hydrogen abstraction and rebound hydroxylation are promising candidates. This promise has made them a target for computational high-throughput screening, typically simplified through the use of linear free energy relationships (LFERs). However, their mid-row transition-metal centers have numerous accessible spin and oxidation states that increase the combinatorial scale of design efforts. Here, we carry out a computational design screen of over 2,500 mid-row 3d transition-metal complexes with four metals in numerous spin and oxidation states. We demonstrate the importance of spin/oxidation state in dictating design principles, limiting the generalization of strategies derived for widely studied high-spin Fe(II) catalysts to other metals or spin/oxidation states. Combined assessment of the effect of ligand field tuning on reaction step energetics and on the identity of the ground state allows us to propose refined design strategies for spin-allowed methane-to-methanol catalysis. We observed weak coupling of energetics and design principles between reaction steps (e.g., oxo-formation vs methanol release), meaning that LFERs do not generalize across our larger catalyst set. To rationalize relative reactivity in known catalysts, we instead compute independent reaction energies and propose strategies for further improvements in catalyst design.
A β-Hairpin Epitope as Novel Structural Requirement for Protein Arginine Rhamnosylation
Authors: Martin Nathaniel , Walvoort Marthe , Yakovlieva Liubov , Wood Thomas , Kemmink Johan , Koller Franziska , Lassak Jürgen , Kotsogianni Ioli
Published: October 2020

Protein N-glycosylation is ubiquitously present in all domains of life, and confers a plethora of functions to the protein including increased solubility, protection from degradation, interaction with receptors, and activation for function. For canonical asparagine glycosylation, the recognition sequence that directs glycosylation at specific asparagine residues is well-established. It generally holds for protein glycosylation that the primary amino acid sequence is most important for substrate recognition. Here we reveal that a recently discovered bacterial enzyme called EarP, that transfers rhamnose to a specific arginine residue in its acceptor protein EF-P, specifically recognizes a β-hairpin loop. Notably, while the rhamnosyltransferase activity of EarP is abolished when presented with linear substrate peptide sequences derived from EF-P in vitro, the enzyme readily glycosylates the same sequence when presented in a cyclized β-hairpin mimic containing an l-Pro-d-Pro motif. Additional studies with other substrate-mimicking cyclic peptides revealed that EarP activity is sensitive to the method used to induce cyclization and in some cases is tolerant to amino acid sequence variation. Using detailed NMR approaches, we established that the active peptide substrates all share some degree of β-hairpin formation, and therefore conclude that the β-hairpin epitope is the major determinant of arginine-rhamnosylation by EarP. Our findings add a novel recognition motif to the existing knowledge on substrate specificity of protein glycosylation, and are expected to inform future identifications of rhamnosylation sites in other protein substrates.

Authors: Yatsenko Hanna
Published: October 2020

This article explores the impact of weather conditions on core sectors of the Ukrainian economy and the composite index of economic activity in Ukraine. We build autoregressive distributed lag (ARDL) models using statistical data provided by the Central Geophysical Observatory named after Boris Sreznevsky (CGO) and the State Statistics Service of Ukraine for the period 2004-2019. The obtained outcomes show that fluctuations in the air temperature and precipitation are significant determinants of output in different sectors (specifically agriculture, construction, manufacturing, and energy). Therefore, the inclusion of weather conditions into models may potentially improve the modeling properties and forecasting of economic activity.

Authors: Carrasco Choque Freddy
Published: October 2020

Mediante el método de función de producción agrícola, se estima económicamente los efectos del cambio climático en la producción y rendimiento de quinua, se concluye que las variables climáticas si afectan la producción y rendimiento de quinua, estos explican más del 60% y 35 % respectivamente. El factor climático que más influye en la producción y rendimiento es la temperatura máxima, a un nivel de significancia del 10%. Las temperaturas optimas son, temperatura máxima 15.2°C, temperatura mínima 5°C y precipitación de 765.5 mm. El comportamiento de los factores climáticos muestra una tendencia creciente, y el efecto hacia la producción y rendimiento son negativas, ya que a medida que se eleva la temperatura sobrepasando el umbral optimo requerido por el cultivo, la producción y rendimiento de quinua se reduce. Según el pronóstico de producción de quinua para los próximos 16 años, los efectos serán perjudiciales no solo para la quinua, sino para todo el sector agrícola, con riesgos desde la disminución de la producción y calidad de los alimentos, ingresos más bajos y alza de precios. Es importante, la implementación de medidas de adaptación y mitigación para el sector agrícola.

IMPORTANCE OF MINING AND AGRICULTURE ON THE PERUVIAN ECONOMY
Authors: Ccama Faustino
Published: October 2020

This paper presents thd Mining and Agriculture sectors contribution to the Peruvian economy. Describes the performance of these sectors, during the last two decades, using macro-economic indicators; besides it describes how  in this period the Peruvian economy shows an impressive growth 5.44%  in terms of  gross domestic product (GDP); this period is also known  as the ¨mining boom¨. The excellent performance of mining and agriculture sectors contributed to this economic performance. However, despite the economic growth and changes during the last two decades, extreme poverty, malnutrition and childhood anemia are still a serious problem. To eliminate the extreme poverty Peru has to grow at least 6% per year in terms of GDP.  This study proposes that mining and agriculture must keep growing, as well as the other sectors to insure   the Peruvian development. It recommends that private and public investment must keep increasing, it recognizes the importance of competitiveness. Another conclusion is that there is no real conflict between mining and agriculture for water resources; since it is needed by both sectors. The recent Peruvian economic is due to the last mining investments and support from the present government.

Im Vergleich zu seinen rüheren Ausätzen versucht Friedrich Schlegel in seinem Roman Lucinde (1799) das, was zuvor als „unendlich Entgegengesetztes“ konzipiert wurde – d. h. die in der Menschheit aundbare Mischung von „Gottheit“ und „Tierheit“ – als „harmonische Zusammensetzung“ darzustellen (KFSA 1: 230). Der vorliegende Beitrag geht der Frage nach, inwiefern sich Friedrich Schlegels narrative ransponierung der „Gottheit“ und der „Tierheit“ als relevant für die Reflexion anthropologischer Konzepte von 1800 bis heute erweist.

According to the data of hydro-magnetic surveying and satellite altimetry, using the original technology for solving the inverse problem, 2D models of the magnetic layer for three latitudinal profiles crossing the submarine plateau of Osborne in the southern, central and northern parts were constructed. Density modeling for these three profiles was carried out using the available worldwide data on free air anomalies, reduced to the Bouguer anomaly. On all profiles, zones of increased effective magnetization with complex morphology are confidently distinguished. The distinguished sources of magnetic anomalies are tending toward two deep horizons. The upper one corresponds to layer 2 of the classical model of the magnetic layer of the oceanic lithosphere and is a source of local magnetic anomalies of both signs. The lower magnetic layer, the bottommost part of which approximately corresponds to the depth of the Moho surface according to density modeling, is apparently composed of serpentinites. The crust is broken by a system of sub-meridional faults, to which confined deep magnetic bodies, possibly associated with serpentinite protrusions. The revealed laterally inhomogeneous deep structure of the magnetic layer of the Osborne plateau and the adjacent NER segment testifies to their complex multi-stage volcano-tectonic evolution, which continues to present day.

The Research Aimed to analyze the competitiveness of physical culture and sports organization on the basis of relevant indicators to manage the competitiveness level of sports enterprise. Research Organization. The study was conducted from October 1, 2019 till February 29, 2020 on the basis of physical culture and sports organization – sports club «Sportexpert». The analysis of the services competitiveness was carried out on the example of the sports enterprise

– sports club «Sportexpert». The integral coefficient method was chosen to assess the competitiveness. Research Results. Competitiveness assessment of physical culture and sports enterprises is impossible without analysis of the services competitiveness they provide. The main advantage of the step-by-step method of competitiveness is the assessment that it involves direct measurement and evaluation of the studied indicators. Furthermore, this technique allows taking into account the significance of certain parameters with the help of weigh coefficients, which makes it possible to determine the degree of their impact on the final integrated indicator of competitiveness. The general index of service competitiveness of visiting the gym in the sports club «Sportexpert» is 0,77. That is, 77 % of sports club visitors are satisfied with the service provided. Conclusions. The obtained results of calculations demonstrate that analyzed sports club generally has good competitiveness assessment. The integral evaluation determination of competitiveness was based on 10 indicators – characteristics of the sports club activity. The strong and weak points of the «Sportexpert» sports club have been defined. The main indicators that needed to be changed were prestige of the club, cost of services, quality of equipment, professionalism of coaches, and efficiency of training programs.

У статті висвітлено актуальність проблеми формування культури здоров’я та здорового способу життя учнів початкової школи закладів середньої освіти. За рахунок процесу інтеграції програми олімпійської освіти в заклади середньої освіти будуватиметься за допомогою крос-курікулярної технології, яка передбачає, що кожен урок – це окремий блок, який має чітко визначену структуру. Діяльність учителя зводитиметься не до ре- трансляції знань, а до створення компетентнісного освітнього середовища для пошуку й відкриттів. Розглянута програма олімпійської освіти, яка є передумовою для того, щоб молодь долучилася до спорту, спричинивши зростання здорового способу життя, позитивного впливу на формування цінностей та особистість. Із метою виявлення ефективності програми з використанням олімпійських цінностей у процесі роботи з учнями закладів середньої освіти міста Херсона проведено комплексну діагностику сформованості поведінкових рис цінностей дітей за допомогою методики  «Олімпійський  опитувальник» Р.  Телама,  метод  семантичного  диференціалу В. Ф. Петренко. Важливою особливістю інтеграції олімпійських цінностей в освітній процес школярів є заохо- чення чіткого й послідовного послання на те, наскільки спорт є важливою частиною культури, що має величезний виховний вплив. Доведено, що з упровадженням у заклади середньої освіти програми олімпійської освіти діти та молодь розуміють, що довговічність, яка зумовлена спортом, висвітлює інші цілі життя й допомагає знайти свій власний шлях у суспільстві. Олімпійський спорт, олімпійська освіта, концепція спортивних занять та виховання особистості в культурі олімпійських цінностей підкреслює значення загальних людських цінностей. Глобальний орієнтир в олімпійській освіті – виховання молодої людини з осмисленням гуманістичних ідеалів, здорового способу життя, позитивного мислення, цінності олімпізму та віри в майбутнє.

Topicality. Adaptation to the higher education system is the most problematic type of adaptation. Regular physical activities cause psychological relaxation and help to withstand emotional overload. Physical сondition has a significant impact on a number of student life indicators. Determining the level of physical condition of students-athletes is the first step in substantiating the process of its improvement, and the orientation of changes in their level determines the effectiveness of the educational process at the Faculty of Physical Education. The Purpose of the Research is to identify and analyze the influence of physical condition level on the adaptive capacity of the cardiovascular system, the psycho-emotional state and the stress resistance level of physical culturist students. The Methodology of the Research. The research was conducted at the Lesya Ukrainka Eastern European National University among students of 1–4 year study on Speciality «Secondary Education. Physical Education» (135 persons, including 90 boys and 45 girls) during the intersession period. The experimental phase of the experiment took place during March-April 2018–2019. and included a study of the psycho-functional and emotional status of the research data sample. The Results the Study. It was found that adolescents are characterized by average and above average level of physical condition; the girls have high level of physical condition. A significant group of students with vegetative balance was noted; every third student has a marked vagotonia as a result of economizing the work of the human body at rest. A satisfactory level of adaptive potential was found as typical for 60 % of boys and 88,9 % for girls. It should be considered as a manifestation of long- term adaptive reaction to physical exertion. The average and high levels of the parameters «well-being» and «mood» were established; by the scale of «activity» – it was unsatisfactory for the vast majority of girls and boys. It was found 62,2 % among boys with reduced levels of stress resistance and with an average level – 36,7 % of students; among girls, 57,8 % and 40,0 %, respectively. This situation indicates the presence of stressful situations in the lives of these  students and their low resistance to them. The strongest feedback was noted between the level of physical condition and heart rate and adaptive capacity.

THE LEVEL OF MORALITY AND RELIGIOSITY OF STUDENTS IN A PHILIPPINE ACADEMIC INSTITUTION: THE BASIS FOR THE CORE VALUES FORMATION
Authors: Bautista Dennis M.
Published: October 2020

This paper determined the level of religiosity and morality of the students. This utilizes descriptive survey and correlational design that use quantitative data. In this approach, the researcher primarily use post positivist claims for developing knowledge and employ survey to collect data. The survey design will yield holistic views of the respondent regarding morality and religiosity through statistical inquiry. The correlational design will measure the degree of association between two or more variables using also statistical procedure of correlational analysis. The respondents are male and female belonging to different age brackets. Most of the respondents are Roman Catholics since Catholicism is still the religion in the Philippines that has the most number of believers. The result reveals that the power of media, side by side with one’s family and environment can be influential to a person’s religiosity and morality. Despite the varying views among the respondents, it was found out that there is a significant relationship among the two variables specifically on factors such as family’s social spectrum and the perceived religious effects of the chosen media. This study is a replication of another study about the religious perspective of students conducted in the same university.

This study examined the influence of investment climate on technical efficiencies of industries in Nigeria. The study was conducted in two phases namely (i) an estimation of the technical efficiency (TE) was carried out and, (ii) differences in TE across firms were statistically related to indicators of investment climate and firm-level characteristics. The analyses made use of 2009 World Bank Enterprise survey data on Nigeria. The results showed that food industry was more labour intensive and less efficient than other industries in Nigeria. The importance of scale, export and firm ownership was evident from the significance of the variables in all the industries. The results point to the fact that firms in Nigeria can improve their productivity by learning from customers and by facing international competition. Investment climate difficulties had less effect on food industries than others.  The sector could be a good starting point in the nation’s industrialization policy drive if available resources can be utilized optimally.

In this study, the aged mechanical properties and the modifier structure were determined. Bio-materials are often used as additives to plastics, in order to make the degradation easier in the environment. We examined the differences of the properties of samples differently aged; the ages of the samples were 1 and 3 years. The properties that were gathered from the mechanical tests, such as tensile-, flexural-, impact-, and hardness-test, show changes depending on the ages of the samples. Due to the aging, decrease of mechanical properties was experienced. The microcellular structures of the composites were studied by SEM analysis in order to understand the changes of the structures. It can be seen on the recording that the corn cob strengthens and sticks to the cells wall. The internal changes of the structure that were caused by the aging cannot be seen on the SEM micrographs.
