Legal responsibility of a scholar for implementation of the results of his scientific activity in the area of reproductive and therapeutical genetic modification of human in the BRICS countries
Authors: Belikova Ksenia Michailovna
Published: July 2020

Based on the legal material of BRICS countries, this article conducts a scientific analysis on the question of legal responsibility of a scholar for implementation of the results of his scientific activity in the area of reproductive and therapeutical genetic modification of human. The relevance is substantiated by the impact upon legal and medical science, as well as the perceptions of peoples and experts (lawyers, medical personnel, sociologists, etc.) affected by new technologies, which currently allow doing what no one could ever imagine, unless in the films or books of science-fiction genre. The author examines different legal scenarios. The scientific novelty consists in the choice of countries – BRICS; the subject of research – legal responsibility for implementation of the results of his scientific activity in the area of reproductive and therapeutical genetic modification of human; analysis of the selected circle of questions in cross-disciplinary aspect, from the perspective of jurisprudence, medicine, and ethics). The conclusion is made that the approaches of national legislation are influenced by a range of problems that justify the corresponding legal regulation (for example, GMO in Brazil, prohibition of prenatal sex discernment in India, situation after He Jiankui’s experiment in China, etc.).

K-Means is the most popular of clustering method, but its drawback is sensitivity to outliers. This paper discusses the addition of the outlier removal method to the K-Means method to improve the performance of clustering. The outlier removal method was added to the Local Outlier Factor (LOF). LOF is the representative outlier’s detection algorithm based on density. In this research, the method is called LOF K-Means. The first applying clustering by using the K-Means method on hotspot data and then finding outliers using the LOF method.  The object detected outliers are then removed.  Then new centroid for each group is obtained using the K-Means method again. This dataset was taken from the FIRM are provided by the National Aeronautics and Space Administration (NASA).  Clustering was done by varying the number of clusters (k = 10, 15, 20, 25, 30, 35, 40, 45 and 50) with cluster optimal is k = 20. The result based on the value of Sum of Squared Error (SSE) shown the LOF K-Means method was better than the K-Means method.

Published: July 2020

The door is an important component in a building as security. It is used as access in and out of a room. People in the modern era now want everyday life that is completely automated, so that the work can be done easily without wasting energy and can shorten the time. Along with the rapid development, the need for effectiveness and efficiency is prioritized in various fields. The purpose of this paper is to design an automatic sliding door that only detects one Radio Frequency Identification (RFID) card to open and close. The use of RFID systems can strengthen the security level of building access. This study uses a data processing method in the form of an ID number generated from a tag. Specifications in the discussion of the results in this study include a motor that uses a 12-volt DC motor, a maximum door weight of 5 kg, can only detect one RFID to open and close the door, and the sliding door used is one door. The results of system testing are obtained to open a door that is without load, and the door can move 14 cm from the distance of the door hole so that it opens. Doors with a load of 1-1.5 kg also move 14 cm from the distance of the door opening when open. Doors with a load of 2-3 kg only move 12.5-9.5 cm from the distance of the door so that it opens. When the door gets heavier 3.5-4 kg, the door moves only 7.5-3 cm from the distance the door hole remains closed.

Effects of some natural products on population of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) on rose plants
Authors: HELVACIOĞLU Özge , AKŞİT Tülin
Published: July 2020

Four products allowed in organic farming (kaolin, insecticidal soap, neem oil soap, spinosad) as alternatives to chemical insecticides, were evaluated for the control of Metopolophium dirhodum (Walker, 1849) (Hem.: Aphididae). In addition, number of the newborn nymph and host selection for the treated and untreated rose (Rosa hybrida L. cv. First Red) leaves were examined. The toxicities of used natural products were compared with the diazinon and control (water). Rose saplings were used as experimental material. The application was repeated twice in the same greenhouse. Evaluations in populations were done on 1, 3, 5, 7, 10 and 14 days after applications. Insecticidal soap showed toxicity between 50.45 % and 74.0 % until fifth day and its toxicity decreased in the following days. Neem oil soap was non-toxic (15.09%–19.71%) at first application but, in the second application, its toxicity was increased (36.96%-72.27%). Repeated kaolin application ended with a positive result of 66.87% control. Spinosad had no effect on aphid. It was observed that M. dirhodum population was decreased by repeated (twice) applications of kaolin, insecticidal soap and neem oil soap. However, they could not control the aphid populations completely. In choice tests, the numbers of living aphids and newborn nymphs on rose leaflets treated with kaolin, neem oil soap, and insecticide soap were lower than those not treated. These three products were found to be repellent for M. dirhodum.

Published: July 2020

Table olive fermentation is one of the oldest
applications in the Anatolia and table olive consumption plays important role
in human nutrition. In this study, 8 traditionally produced olive samples and
one industrially produced table olive sample were obtained from Aydın province.
Microbial populations were determined by standard plate counts for mesophilic
bacteria, lactic acid bacteria (LAB), Enterobacteriaceae, Staphylococci, mold
and yeasts. Forty one representative lactobacilli were characterized by
phenotypic techniques. Among them 34 of isolated strains have good growth abilities
both at 15°C and 6.5% salt concentration. Additionally, those lactobacilli
strains have homofermentative character and these are desired properties for
table olive starters. For species level identification, four representative
strains selected from sugar fermentation profiles were characterized by 16S
rDNA sequencing. Three of them
matched with Lb. plantarum and one of
them matched with Lb. pentosus. These
strains produced conjugated linoleic acid between 12-20 µg/ml with presence of
linoleic acid. Finally, those LAB strains with desired technological properties
can be used in controlled industrial table olive productions in the future.

Authors: Торбик Д.В.
Published: July 2020

В представленном исследовании анализируются среднесрочные клинические результаты внедрения биполярной техники выполнения трансуретральной резекции и энуклеации в лечении доброкачественной гиперплазии предстательной железы (ДГПЖ) объемом более 80 см3.
В исследование включено 84 пациента (основная группа), оперированных методом трансуретральной энуклеации предстательной железы, и 112 пациентов – методом биполярной трансуретральной резекции предстательной железы (контрольная группа). При применении исследуемых эндоскопических методов средний срок послеоперационной катетеризации составил 1,3 суток в основной группе и 1,4 дня в группе контроля, интра- и послеоперационные осложнения (кровотечение, инфекционно-воспалительные осложнения) были единичными, причем меньшая частота встречалась в основной группе. Через 6 месяцев после операции скорость потока мочи возросла на 13,9 мл/с в основной группе и на 10,9 мл/с в группе контроля, средний балл по шкале IPSS в итоге составил 3,2±0,2 балла и 4,1±0,1 балла в основной и контрольных группах соответственно (p<0,05).
Полученные результаты в основной группе можно связать с большей радикальностью методики трансуретральной энуклеации простаты (ТУЭБ), объем резидуальной ткани узла в этой группе составил 5,6±0,7 см3 против 14,8±3,2 см3 в группе контроля (p<0,05). Таким образом, метод ТУЭБ может быть рекомендован к освоению врачам-урологам специализированных стационаров, как способ оперативного лечения ДГПЖ крупных размеров.

In the present study, the mid-term clinical results of the introduction of the bipolar technique of performing transurethral resection and enucleation in the treatment of benign prostatic hyperplasia (BPH) of more than 80 cm3 are analyzed.
The study involved 84 patients who underwent transurethral enucleation of the prostate (treatment group) and 112 patients – bipolar transurethral resection of the prostate (control group). In applying the endoscopic techniques under study, the mean duration of postoperative catheterization was 1.3 days in the treatment group and 1.4 days in the control group; intra- and postoperative complications (bleeding, infectious and inflammatory complications) were incidental with lower occurrence in the treatment group. In 6 months after surgery, the urinary flow rate increased by 13.9 mL/s in the treatment group and by 10.9 mL/s in the control group, the average score on the IPSS scale was 3.2 ± 0.2 points and 4.1 ± 0.1 points in the main and control groups, respectively (p <0.05).
The results obtained in the main group can be attributed to the more radical methods of transurethral enucleation of the prostate (TEOB), the volume of residual tissue in this group was 5.6 ± 0.7 cm3 against 14.8 ± 3.2 cm3 in the control group (p<0,05). Thus, the TEOB method can be recommended for mastering by urologists of specialized hospitals as a method of surgical treatment of large-size BPH.

В статье представлен опыт внедрения нового метода лечения доброкачественной гиперплазии предстательной железы (ДГПЖ) - трансуретральной биполярной энуклеации простаты (ТУЭБ) в арсенал хирургических методов урологического отделения "Клинической больницы "РЖД - Медицина" г. Саратов. Статистические данные по контролю были получены ретроспективным методом из архива историй болезни. Статистическую обработку результатов исследования проводили при помощи параметрического критерия t Стьюдента. Различия показателей считались достоверными при уровне значимости р ≤ 0,05.
Анализ общих операционных результатов и клинической эффективности нового метода (89 чел.) проведен в сравнении с ретроспективными данными по методу открытой простатэктомии (ОПЭ - 91 чел.), ранее применявшегося в отделении для лечения пациентов данного профиля.
Установлено, что применение ТУЭБ вместо ОПЭ при средних и больших объемах ДГПЖ позволяет в 2-3 раза снизить кровопотерю во время операции, сроки послеоперационного дренирования мочевого пузыря и общую продолжительность госпитализации при минимальном количестве интра- и послеоперационных кровотечений и при отсутствии осложнений инфекционно-воспалительного характера.
Полученные результаты свидетельствуют о перспективности применения ТУЭБ вместо травматичной ОПЭ, так как это позволяет оптимизировать хирургические результаты и экономические показатели лечения ДГПЖ.

The article presents the experience of the introduction of a new method of treatment of benign prostatic hyperplasia (BPH) - transurethral bipolar prostate enucleation (TUEB) in a set of surgical methods of the urological Department of the "Clinical hospital "Russian Railways - Medicine" of Saratov. Statistical data on control were obtained by retrospective method from the archive of medical records. Statistical processing of the results of the study was carried out using the parametric t-student test. The differences were considered significant at the significance level p ≤ 0.05.
The analysis of the general operating results and clinical effectiveness of the new method (89 people) was carried out in comparison with the retrospective data on the method of open prostatectomy (OPE - 91 people), previously used in the Department for the treatment of patients of this profile.
It was found that the use instead of OPE for medium and large volumes of BPH allows 2-3 times to reduce blood loss during surgery, the timing of postoperative drainage of the bladder and the total duration of hospitalization with a minimum amount of intra- and postoperative bleeding and in the absence of complications of infectious and inflammatory nature.
The results indicate the prospects instead of traumatic OPE, as it allows to optimize the surgical results and economic indicators of treatment of BPH.

В статье представлено сравнительное исследование результатов применения плазменных эндоскопических технологий и открытой простатэктомии в лечении доброкачественной гиперплазии предстательной железы (ДГПЖ) средних и больших размеров.
Базой, на которой было проведено исследование, явился Центр эндоурологии ГАУЗ ГКБ №7, город Казань. Оценка периоперационных результатов эндоскопических методов лечения ДГПЖ был проведен на основе текущего наблюдения за период 2015-2018 годы.
При равной хирургической эффективности методов коллективом авторов установлено, что использование эндоуретральных методик дает достоверное снижение количества интра- и послеоперационных осложнений. Уменьшение геморрагических и инфекционно-воспалительных осложнений во время операции и в раннем послеоперационном периоде приводит к сокращению сроков дренирования мочевого пузыря и продолжительности госпитализации. Применение современного оборудования, функционирующего на платформе "ПЛАЗМА", в сравнении с ранее используемым оборудованием для биполярных операций позволяет сократить время оперативного вмешательства при выполнении эндоскопической энуклеации.
Выявленные преимущества трансуретральных методов лечения ДГПЖ свидетельствует о более высоком профиле их безопасности и эффективности, что дает основание для включения плазмокинетических эндоуретральных методов операций в стандарт урологического лечения пациентов данного профиля.

The article presents a comparative study of the results of plasma endoscopic technologies and open prostatectomy in the treatment of benign prostatic hyperplasia (BPH) of medium and large sizes.
Foundation on which the study was conducted, was the Center of endourology at REGIONAL clinical hospital №7, Kazan. Evaluation of perioperative results of endoscopic treatment of BPH was carried out on the basis of current observation for the period 2015-2018.
With equal surgical efficiency of the methods, the team of authors found that the use of endourethral techniques gives a significant reduction in the number of intra- and postoperative complications. Reduction of hemorrhagic, infectious and inflammatory complications during surgery and in the early postoperative period leads to a reduction in the duration of bladder drainage and the average duration of hospitalization. The use of modern equipment operating on the platform "PLASMA", in comparison with the previously used equipment for bipolar operations can reduce the time of surgical intervention in the performance of endoscopic enucleation.
The revealed advantages of transurethral methods of treatment of BPH indicate a higher profile of their safety and efficiency, which gives grounds for the inclusion of plasma kinetic endourethral methods of operations in the standard urological treatment of patients of this profile.

Published: July 2020

We explore a novel ether aided superconcentrated ionic liquid electrolyte; a combination of ionic liquid, N-propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide (C3mpyrFSI) and ether solvent, 1,2 dimethoxy ethane (DME) with 3.2 mol/kg LiFSI salt, which offers an alternative ion-transport mechanism and improves the overall fluidity of the electrolyte. The molecular dynamics (MD) study reveals that the coordination environment of lithium in the ether aided ionic liquid system offers a coexistence of both the ether DME and FSI anion simultaneously and the absence of ‘free’, uncoordinated DME solvent. These structures lead to very fast kinetics and improved current density for lithium deposition-dissolution processes. Hence the electrolyte is used in a lithium metal battery against a high mass loading (~12 mg/cm2) LFP cathode which was cycled at a relatively high current rate of 1mA/cm2 for 350 cycles without capacity fading and offered an overall coulombic efficiency of >99.8 %. Additionally, the rate performance demonstrated that this electrolyte is capable of passing current density as high as 7mA/cm2 without any electrolytic decomposition and offers a superior capacity retention. We have also demonstrated an ‘anode free’ LFP-Cu cell which was cycled over 50 cycles and achieved an average coulombic efficiency of 98.74%. The coordination chemistry and (electro)chemical understanding as well as the excellent cycling stability collectively leads toward a breakthrough in realizing the practical applicability of this ether aided ionic liquid electrolytes in lithium metal battery applications, while delivering high energy density in a prototype cell.

Published: July 2020

Driving rapid polymerizations with visible to near-infrared (NIR) light will enable nascent technologies in the emerging fields of bio- and composite-printing. However, current photopolymerization strategies are limited by long reaction times, high light intensities, and/or large catalyst loadings. Improving efficiency remains elusive without a comprehensive, mechanistic evaluation of photocatalysis to better understand how composition relates to polymerization metrics. With this objective in mind, a series of methine- and aza-bridged boron dipyrromethene (BODIPY) derivatives were synthesized and systematically characterized to elucidate key structure-property relationships that facilitate efficient photopolymerization driven by visible to NIR light. For both BODIPY scaffolds, halogenation was shown as a general method to increase polymerization rate, quantitatively characterized using a custom real-time infrared spectroscopy setup. Furthermore, a combination of steady-state emission quenching experiments, electronic structure calculations, and ultrafast transient absorption revealed that efficient intersystem crossing to the lowest excited triplet state upon halogenation was a key mechanistic step to achieving rapid photopolymerization reactions. Unprecedented polymerization rates were achieved with extremely low light intensities (< 1 mW/cm2) and catalyst loadings (< 50 μM), exemplified by reaction completion within 60 seconds of irradiation using green, red, and NIR light-emitting diodes.
Exchange Spin Coupling fromGaussian Progress Regression
Authors: Bahlke Marc Philipp , Mogos Natnael , Proppe Jonny , Herrmann Carmen
Published: July 2020

Heisenberg exchange spin coupling between metal centers is essential for describing and understanding the electronic structure of many molecular catalysts, metalloenzymes, and molecular magnets for potential application in information technology. We explore the machine-learnability of exchange spin coupling, which has not been studied yet. We employ Gaussian process regression since it can potentially deal with small training sets (as likely associated with the rather complex molecular structures required for exploring spin coupling) and since it provides uncertainty estimates (“error bars”) along with predicted values. We compare a range of descriptors and kernels for 257 small dicopper complexes and find that a simple descriptor based on chemical intuition, consisting only of copper-bridge angles and copper-copper distances, clearly outperforms several more sophisticated descriptors when it comes to extrapolating towards larger experimentally relevant complexes. Exchange spin coupling is similarly easy to learn as the polarizability, while learning dipole moments is much harder. The strength of the sophisticated descriptors lies in their ability to linearize structure-property relationships, to the point that a simple linear ridge regression performs just as well as the kernel-based machine-learning model for our small dicopper data set. The superior extrapolation performance of the simple descriptor is unique to exchange spin coupling, reinforcing the crucial role of choosing a suitable descriptor, and highlighting the interesting question of the role of chemical intuition vs. systematic or automated selection of features for machine learning in chemistry and material science.
Copper(II) Complexes of N-Propargyl Cyclam Ligands Reveal a Range of Coordination Modes and Colours, and Unexpected Reactivity

Published: July 2020

Herein we describe single crystal X-ray diffraction and spectroscopic investigations of the coordination chemistry of copper(II) complexes of cyclam derivatives with between 1 and 4 pendant alkynes. The crystal structures of these copper complexes unexpectedly reveal a range of coordination modes, and the surprising occurrence of five unique complexes within a single recrystallisation of the tetra-N-propargyl cyclam ligand. One of these species exhibits weak intramolecular copper-alkyne coordination, and another is formed by a surprising intramolecular copper-mediated hydroalkoxylation reaction with the solvent methanol, transforming one of the pendant alkynes to an enol ether. Multiple functionalisation of the tetra-N-propargyl ligand is demonstrated via a ‘tetra-click’ reaction with benzyl azide, and the copper-binding behaviour of the resulting tetra-triazole ligand is characterised spectroscopically.

Machine learning solved many challenging problems in computer-assisted synthesis prediction (CASP). We formulate a reaction prediction problem in terms of node-classification in a disconnected graph of source molecules and generalize a graph convolution neural network for disconnected graphs. Here we demonstrate that our approach can successfully predict reaction outcome and atom-mapping during a chemical transformation. A set of experiments using the USPTO dataset demonstrates excellent performance and interpretability of the proposed model. Our model uses an unsupervised approach to atom-mapping and bridges the gap between data-driven and traditional rule-based methods. Implicitly learned latent vector representation of chemical reactions strongly correlates with the class of the chemical reaction. Reactions with similar templates group together in the latent vector space.

Ciudades (No) Blandas
Authors: Grillo Cuello Andrés
Published: July 2020

Reseña del texto curatorial de “Ciudades (No) Blandas”, exposición fotográfica del artista Leonardo Portus realizada en el Centro Cultural Palacio La Moneda (CCPLM), Santiago de Chile, entre octubre de 2019 y Abril de 2020.

 En él se aborda el tránsito investigativo que ha tenido Portus desde sus trabajos previos, de tipo instalativo, al fotográfico, enfatizando su continua búsqueda, en donde la arquitectura abre un diálogo con el urbanismo, la historia y el paisaje, desde el campo de las artes visuales contemporáneas. También, ilustra acerca del origen del nombre de la exposición y su relación con los sucesos de Chile antes y después del Golpe de Estado de 1973, de un modo ucrónico, dándose a entender el vínculo de Portus con la historia, su método de trabajo, sus temáticas, y el modo de fabricar sus objetos, esta vez en sintonía con los hallazgos, Duchamp, Benjamin y Ranciere, como arqueólogo de la Modernidad.

Professor coordenador na formação contínua de professores: um estudo em escolas do município de Limeira
Authors: Estessi Bento Antunes Luciana , Ramos de Azevedo Maria Antonia
Published: July 2020

O artigo discute o papel do professor coordenador pedagógico no cotidiano escolar frente à formação contínua de professores nos espaços de Horas de Trabalho Pedagógico Coletivo (HTPC). Refere-se à pesquisa de Mestrado, realizada em 2013, em nove escolas do município de Limeira (SP), de cunho qualitativo em Educação. Possibilitou o maior entendimento de que a formação do professor é um processo inerente ao papel do coordenador pedagógico no espaço do cotidiano escolar, que não se finaliza com a formação inicial; ao contrário, impõe-se como indispensável à formação contínua, para que práticas profissionais se tornem a base da formação.

Authors: Martins da Silva Provin Willie Anne , Barazzetti Vanessa Rita , Filipak Sirley Terezinha
Published: July 2020

Para analisar a concepção de educação em tempo integral exis­tente na Lei de Diretrizes e Bases da Educação Nacional (LDBEN) – Lei n. 9.394/1996, após sua modificação pela da Lei n. 13.415 de 16/02/2017, este artigo se propõe a verificar se esta concep­ção atende aos interesses das comunidades escolares. As condi­ções precárias das escolas públicas brasileiras para a implantação e administração da educação em tempo integral revelam a lacuna existente para a concretização dos objetivos da legislação vigente, resultado de uma política educacional elaborada sem a participa­ção da comunidade escolar.
