Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp) was used for timber construction even they have low quality on the durability. The efforts need to improve their durability, especially against subterranean termites, the most destructive wood organism. One methods of preservation which can improve the durability was fumigation. Fumigation can be processed with traditional methods and modern methods. The aim of the study was to improve the durability of Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp)with modern fumigation methods and evaluation the durability against subterranean termites Coptotermes curvignathus Holmgren. Wood sample was measured 2 cm x 2 cm x 1 cm. The fumigation treatment was conducted with oven. The oven size was 1 m x 1 m x 50 cm. Treatments of fumigation consits of 12 hours and 24 hours. The treatment of evaluation the durability agaisnt termites was conducted for 21 days. The wood sample was put on the bottle and 50 termites consist of 45 workers and 5 soldiers were put in the wood sample. The parameter of indicator was termite’s mortality and wood weight loss. Result of the research showed that average termites mortality was reach 100% at wood sample with fumigation method for 24 hours, and 89.2% for wood sample with fumigation method for 12 hours. Meanwhile in control wood the termite’s mortality only 8.6%. The level of termites mortality with fumigation methods for 24 hours was classified very strong and for fumigation methods for 12 hours was classified as strong. The average wood weight loss was 1.21% - 1.30%. This wood weight loss was classified as very low. From the research it is concluded that fumigation method can increased the durability of wood, both on Medang wood and Bintangur wood against the subterranean termites Coptotermes curvignathus Holmgren. The optimal fumigation methods was on 12 hours, both on Medang wood and Bintangur wood.Keywords: Calophyllum sp, Chinnamumum sp, Coptotermes curvignathus, fumigation, wood preservation

En la industria minera, los concentrados de cobre, plomo y zinc son comúnmente castigados de manera comercial por su alto contenido de arsénico. En busca de combatir esta problemática, se caracterizó un mineral proveniente de Fresnillo, Zacatecas, con importantes concentraciones de este metal tóxico a fin de someterlo a un baño alcalino y lograr la separación del arsénico del resto del mineral. El análisis químico realizado a la muestra del mineral mediante la técnica de Espectroscopia de Emisión de Plasma Acoplada por Inducción (ICP) y Fluorescencia de Rayos X (FRX) identificó un alto contenido de Fe (17.94 % w/w) y As (12.95 % w/w), los cuales forman parte del sulfuro complejo identificado como arsenopirita (FeAsS) [96-900-0110]. Además, la presencia de estos elementos fue corroborada mediante las técnicas de DRX, MEB-EDS y MOP. Estas ténicas tambien revelaron la presencia de sulfuros de metales base como ZnS y PbS, así como especies de ganga como SiO2 y algunos elementos minoritarios como: Sb, Ag, Cu, Zn y Pb. La construcción de diagramas de Pourbaix utilizando el sistema Fe-As-S-NaOH-H2O a 25 °C, permitió determinar que las especies AsO4 3- y FeO*OH predominan bajo las condiciones experimentales a las que se llevaron a cabo las pruebas preliminares ([Mineral]= 8 g L-1, [NaOH]= 2 mol L-1, 25 °C, RPM= 800 min-1 y 720 min), logrando la disolución de 47 % del semimetal.

El titanato de bario es el primer cerámico ferroeléctrico y un buen candidato para una variedad de aplicaciones debido a sus excelentes propiedades dieléctricas, ferroeléctricas y piezoeléctricas, es miembro de una gran familia de compuestos llamadas perovskitas. En el presente trabajo se realiza una revisión de la sinterización de 4 muestras de BaTiO3 dopado con Eu3+, fueron simuladas en el software termodinámico FactSage 7.2, utilizando los pesos moleculares de BaCO3, TiO2 y Eu2O3 en el rango de temperaturas de 25 a 1300 °C. Experimentalmente, las muestras fueron sintetizadas mediante la molienda de BaCO3, TiO2 y Eu2O3 en un mortero de ágata con acetona como medio de control. Los polvos precursores fueron mezclados y calcinados a 800 °C, sinterizados a 1300°C por 5 horas. Los resultados de la simulación termodinámica indicaron que el porcentaje de BaTiO3 formado durante la sinterización fue: 84 %, 76.8%, 65.5% y 57.7% para x=0.001, x=0.10, x=0.25, x=0.35 respectivamente. Los resultados experimentales obtenidos por difracción de rayos x mostraron la fase BaTiO3 tetragonal predominante para bajas concentraciones de Eu3+ y fases secundarias (Eu2TiO5, Eu2Ti2O7) para mezclas con altas concentraciones de Eu3+, estas últimas, no fueron mostradas en el estudio de simulación debido a la ausencia de datos termodinámicos de estas especies, sin embargo, la concordancia de los resultados por ambas técnicas en cuanto a la generación de BaTiO3 fue amplia, ya que en la literatura existe poca información de resultados termodinámicos mediante el software, este trabajo brinda un panorama más amplio para la generación del BaTiO3.

Published: October 2019

El acuífero Apan se localiza en la porción suroriental del Estado de Hidalgo. Debido a que han sido reportados valores de metales en pozos de abastecimiento público por encima de la norma mexicana para agua potable, este estudio se enfocó en analizar el comportamiento de estos posibles contaminantes en su recorrido por el acuífero.
Con información de los organismos locales, se analizaron los resultados para calcio, magnesio, sodio, potasio, cloruro, sulfato, carbonatos, bicarbonatos, fosfatos, aluminio, plomo, mercurio, cadmio, cobre zinc, hierro, manganeso boro, arsénico y fluoruros. De ellos únicamente los que se encontraban en cantidades por encima de los límites de detección del equipo fueron Fe, F y en algunos casos Mn por lo que únicamente los dos primeros se consideraron en el estudio.
De acuerdo a dicha información, se corrobora que la facies hidrogeoquímica presente en la dirección del flujo subterráneo es del tipo bicarbonatada-mixta (bicarbonatada cálcica/magnésica a bicarbonatada sódica/cálcica), lo que indica un tipo de agua joven procedente del agua de lluvia y/o de flujo de tipo local con tendencia a un intercambio iónico entre Ca++ y Mg++.
El Fe presenta una tendencia de aumento en dirección espacial O-E. Los fluoruros presentan una tendencia ascendente con dirección concéntrica en el acuífero.

Resumo: O objetivo desse estudo foi analisar o processo avaliativo na modalidade à distância. A utilização da tecnologia na educação é um dos temas mais recorrentes na literatura acadêmica. Em relação à metodologia foi realizada uma pesquisa bibliográfica e uma pesquisa de campo, onde foram aplicados questionários com 18 professores para verificar a percepção dos mesmos sobre a Avaliação em Ambientes Virtuais de Aprendizagem. Como resultados, verificou-se que para os docentes entrevistados a avaliação nos ambientes virtuais são diferentes das avaliações no âmbito presencial. Ressaltaram que o meio virtual instiga novos olhares e aguça a capacidade dos docentes em utilizar as suas habilidades para interpretarem os resultados do desenvolvimento cognitivo, ou seja, do conteúdo aprendido pelos alunos. Concluiu-se que entre as vantagens da avaliação nos AVA é que este é um poderoso instrumental interacional capaz de alterar as possibilidades de relação entre os sujeitos envolvidos, viabilizando, assim, condições indispensáveis ao caráter dialógico da educação. Entre as principais desvantagens estão a necessidade de um elevado grau de maturidade e compromisso por parte do aluno, dificuldade em separar os conteúdos importantes e o aluno precisa ter um conhecimento, pelo menos básico, para que consiga estudar no ambiente tecnológico.Palavras-chave: Tecnologia.

EVALUATION OF SELF-FERTILITY IN BLACK CURRANT CULTIVARS IN THE NORTHWEST OF RUSSIA
Authors: Tikhonova O. A. 
Published: October 2019

Background. High yield is one of the main requirements for modern black currant cultivars. It depends on many factors, but is always linked to self-fertility. Highly selffertile cultivars are of particular importance in areas with unfavorable weather conditions during flowering, because they are able to provide high yields even in single-cultivar plantings. In this regard, it is very important to study selffertility of cultivars in order to identify those with the highest level of this character for use in breeding and large-scale cultivation.Materials and methods. The study of selffertility was carried out at Pushkin and Pavlovsk Laboratories of VIR in 2014–2017. Fifty-seven black currant cultivars of different genetic and ecogeographic origin were the material of the research. The degree of self-fertility was measured by conventional techniques in 3 variants of pollination: 1) natural self-pollination; 2) artificial self-pollination; and 3) free pollination. Statistical data processing was performed using Microsoft Excel and the guidelines by B. A. Dospekhov.Results and conclusions. Highly self-fertile cultivars were identified, which may be recommended for breeders as sources of this trait: ‘Navlya’ (k-42228), ‘Dobrynya’ (k-42121), ‘Golubichka’ (k-32624), ‘Golosievsky velikan’ (k-44176), ‘Valentina’ (k-15631A), ‘Kozatskaya’ (k-44187), ‘Arapka’ (к-44175), ‘Kanakhama’ (k-44197) and ‘Fat’ (k-42509). High yield in the Northwest of Russia can be secured by cultivars that combine high self-fertility with large fruit size: ‘Valentina’ (k-15631A), ‘Vernisazh’ (k-43126), ‘Garmoniya’ (k-40677), ‘Dobrynya’ (k-42121), ‘Desertnaya Ogoltsovoy’(k-45670), ‘Joninai’ (k-43124), ‘Kanakhama’ (k-44197), ‘Karri (k-44172), ‘Mila’ (k-40673), ‘Sevchanka’(k-45551), ‘Sofievskaya’(k-43131), ‘Talisman’ (k-44183), ‘Yubileinaya Kopanya’ (k-44189), ‘Shalunya’(k-41988), and accession 2780-20-33 (k-15575A). It is shown that free pollination and artificial self-pollinationprovide a positive impact on the fruit setting level, fruit weight and seed productivity. Natural autogamy, on the contrary, tends to decrease the weight of berries and the number of seeds in them.
EXPERIENCE IN PRESERVING THE GENETIC DIVERSITY OF STONE FRUITS USING THE BORDER HEDGING TECHNOLOGY
Authors: Eremin G. V. , Gasanova T. A. , Eremin V. G. , Chepinoga I. S. 
Published: October 2019

Conservation of the world’s plant genetic resources is one of the most significant and relevant problems of mankind. At Krymsk Experimental Breeding Station of VIR, where the largest stone fruit plant genetic diversity in Russia is assembled (more than 5 thousand genotypes: cultivars and species, wild forms, distant hybrids and polyploids), a collection maintenance technology of ‘border hedging’ has been developed and successfully used. This method makes it quite economical (in terms of space reduction, simplification of the system of care for the storage garden, and decreasing the use of chemical protection agents) to maintain a large number of live accessions ex situ. The border hedging technology is based on a propagule nursery system that enables plants to grow longer than in conventional gardens, constantly keeping them in a state of active growth. The basic elements of this technology are dense arrangement of plants (intervals for high-growing plants: 4.0–5.0 m between rows, and 1.0–1.5 m in a row; for low-growing ones: 2.5 m between rows, and 0.5–1.0 m in a row) and annual pruning of shoots at a height of 1.0–1.2 m. Years of experience in using a denser planting pattern for collection garden maintenance helped to identify a number of most significant factors in this system, which make up the scientific basis of the technology for optimally efficient preservation of genotypes and their genetic compliance (representativeness). Among them are biological features of the in situ plant growth habit, including vigor, selection of rootstock or decision on own-root cultivation, layout of the plot, and maintenance system. If it is necessary to study the accessions in the garden where they are preserved in order to make their initial evaluation (approbation, morphological description, study of crop structure, biochemical or biotechnological assessment, analysis of resistance to biotic and abiotic stressors), the plants should not be pruned for 1–2 years. Upon completion of these works, the trees are coppiced again.

Published: October 2019

Background. Resistance to lodging is a factor that significantly affects the yield of barley under the conditions of irrigated agriculture and intensive type of farming. Barley resistance to lodging depends on many features, among which the length of the plant stem is more important.Materials and methods. In the southern planar area of Dagestan, from 1993 till 2008, a research was conducted on the intraspecific diversity of cultivated barley (Hordeum vulgare L.) belonging to different ecogeographic groups, and growth types (2,021 accessions). The F1, F2 and F3 hybrids from crosses of the long-stemmed cultivar ‘Sonet’ with semi-dwarf forms were also studied. The selected recombinant lines were evaluated for their productivity and resistance to frit fly (Oscinella frit L.).Results and conclusions. Wide variability (55–155 cm) of cultivated barley in plant height was observed. Under irrigation in the southern Dagestan, the optimum height of plants, providing high resistance to lodging, was 100–115 cm. A number of semidwarf cultivars were identified; among them, ‘Camincent’ (k-30374, Estonia), ‘Pyramid’ (k-30564, France), ‘Ramos’ (k-30315, Moscow Province) and ‘Jo 1632’ (k-30459, Finland) were the most interesting for their set of traits. The short stem of these cultivars is controlled by recessive alleles of genes. We selected productive lines that significantly exceeded their parental forms in grain weight per area unit and resistance to frit fly: L 15/4 (F6 Sonet × Camincent) and L 16/12 (F6 Sonet × Pyramid). These lines can be used to breed lodging-resistant large-grain barley cultivars for cultivation on irrigated lands.
Об одном неудавшемся замысле, или Мемориальная доска Всеволоду Вишневскому в Таллине
Authors: Biełobrowcewa Irina 
Published: October 2019

В статье упоминается имя Михаила Булгакова в газетной дискуссии периода перестройки, когда в 1987 году группа эстонских интеллектуалов выступила против идеи финансирования мемориальной доски в Таллинне для Всеволода Вишневского, бывшего апологета коммунистического режима. Существование цензуры делало невозможным для эстонских писателей высказывать свои аргументы непосредственно по этому вопросу, поэтому они использовали эвфемизмы для того, чтобы связать протест с действиями Вишневского, связанными с преследованием Михаила Булгакова. Обсуждение публикуемых позднее в эстонской и центральной прессе полемических статей выявляет механизм переноса политического спора в область литературы. В новой социально-политической ситуации имя Михаила Булгакова, подвергшегося преследованиям в 1920-1930-х годах, становится мощной опорой протеста против политическим решениям.
Сыр, «Чайка» и шапка-ушанка в мотивной структуре романа Михаила Шишкина «Взятие Измаила»
Authors: Kuchina Tatiana Gennadevna 
Published: October 2019

В статье исследуется возникновение и развертывание в романе Михаила Шишкина «Взятие Измаила» мотивных цепочек, в которых опорными компонентами становятся столь разнородные образы, как шапка-ушанка, велосипед, сыр, Чайка, заяц, крепость и некоторые другие. Мотивная сеть служит экспликации сквозных, инвариантных тем Михаила Шишкина (слитности жизни и смерти, прошлого и настоящего, видимого и невидимого). Мотивный набор представлен в вариативных сочетаниях (шапка-ушанка + велосипед, шапка-ушанка + заяц, велосипед + рыжеволосая девушка, рыжеволосая девушка + Чайка); при этом семантическое мерцание мотивов (Чайка как пьеса Чехова и модель автомобиля; сыр для дрессированных мышей и сыр-cheese как речевой жест) создает дополнительные валентности для образования новых мотивных связей. Тем самым мотивная комбинаторика противостоит центробежным силам сюжетных разветвлений, заштопывая хронологические разрывы и соединяя истории, развертывающиеся в разных пространственно-временных локациях. Скрытые отражения достраивают каркас того или иного микросюжета и позволяют ему свободно перемещаться из одной сюжетной линии в другую

Hypocenter relocations and tsunami simulation for the 15 November 2014 Northern Molucca Sea earthquake in Indonesia
Authors: Gusman Aditya Riadi , Nugraha Andri D. , Shiddiqi Hasbi Ash 
Published: October 2019

A reverse fault earthquake (Mw 7.1) occurred in the Northern Molucca Sea, Indonesia, on 15 November 2014 at 2:31:40 UTC. The earthquake produced small tsunami waves that are recorded at Jailolo (9 cm), Tobelo (1 cm), and Menado (3 cm) tide gauges. The Indonesian Agency for Climatology, Meteorology, and Geophysics (BMKG) issued a timely (5 minutes after the earthquake) tsunami warning for the event. We used the teleseismic double‐difference seismic tomography method (teletomoDD) to relocate the hypocenters of the mainshock and the aftershocks. The relocated hypocenter of the mainshock for the 2014 Northern Molucca Sea earthquake is located at 1.923°N, 126.539°E, and depth of 48.87 km. In general, the relocated aftershock hypocenters are shallower than those from the BMKG catalog. The relocated hypocenters are distributed within a depth range of 6 to 64 km. The aftershock area from the relocated hypocenters is 80 km long and 55 km wide. The estimated seismic moment from the Global CMT solution (GCMT) was 4.75 × 1019 Nm. We simulated the tsunami from fault model of each GCMT nodal plane to find a fault model that can best explain the observed tsunami heights at Jailolo, Tobelo, and Menado tide gauges. The best single fault model for this event is dipping to the west, has fault length, width, and slip amount of 47 km, 25 km, and 1.16 m, respectively. The K value calculated using the observed and simulated tsunami heights for this best model is 1.026, suggests a very good fit to tsunami observations.
