Abstract. The Bendosari village which is located at Sukoharjo is an area with a far distance to the center of the city. It is difficult to rich this area unless someone do it purposely. Under this cirumstances, the access for preacher from outside the villagers in order to contribute in developing Islamic teaching among them is quite difficult. While that is the hindrance for the preacher to reach the area, the villagers themselves mostly are occupied as farmer who will deal with the zakat of plantation in their daliy life. The lack of preacher at the area and the day to day dealing with zakat matters create a necessity to make community engagement with the citizen. Here the author tries to investigate the exact necessity of the villagers and then deals directly with their problem by conducting a seminar to them. The result shows that villagers understanding on zakat matter, especially for the paddy increase significantly after the seminar.

Abstrak. Desa Bendosari yang berlokasi di Sukoharjo adalah sebuah area yang terletak cukup jauh dari pusat kota. Cukup sulit untuk mencapai area ini kecuali memang orang tersebut berniat untuk mengunjunginya. Dengan kondisi seperti ini, akses untuk para penceramah dari luar desa untuk dapat memberi sumbangsih terhadap pengetahuan keagamaan Islam menjadi terkendala. Pada saat penceramah mempunyai kendala untuk mengakses area tersebut, para penduduk desa sendiri kebanyak bermatapencaharian sebagai petani yang kehidupannya selalu bersinggungan dengan zakat tanaman pada kegiatan harian mereka. Kurangnya jumlah penceramah pada desa tersebut serta kegiatan harian yang bekenaan dengan zakat tanaman menjadikan kegiatan pengabdian masyarakat dibutuhkan. Pada artikel ini penulis mencoba untuk menginvestigasi keperluan dari para penduduk desa untuk kemudian diberikan solusinya kepada mereka dengan cara memberikan seminar. Hasil menunjukkan bahwa para pemahaman penduduk desa terkait zakat tanaman, khususnya zakat padi meningkat secara signifikan setelah diadakannya seminar.

Love as absolute challenge – also for education
Authors: Rajský Andrej
Published: January 2020

The other (alter), through the lens of Levinas`s criticism of the same (neutrum), is always a unique other who stands up to any generalisation and homogenisation. According to a heteronomous schedule of ethics by E. Levinas, “face of the other”, presence of their personal Thou in the sphere of life of a moral subject, precedes own being of this subject by their calling for an answer. Uniqueness of interpersonal relationship and appeal of the exterior Thou challenges human to exclusivity and to infinite self-abandonment in favour of the other (challenges to love). This ethical horizon is not possible to be ever reached and closed, it is impossible in fact, too difficult to be accepted as a norm of everyday life, mainly life in a community, society, state. Presence of “the third” (the political) in the sphere of morality is posed as a theoretical problem: What kind of ethics should be designed in a society of many “others” where Thou is inevitably turned to He/ She, included in socio-political structures and relationships of justice? Is it possible to talk about some continuum between the relationship to the other and the relationship to a community? The final part of the paper seeks to answer these questions and pedagogical implications of demands of love in moral education are pointed out.
Is it possible and necessary to cultivate love? Education to love according to „Summa Theologiae” of Thomas Aquinas
Authors: Wiesenganger Marek
Published: January 2020

The author researches the issue of love in Thomas Aquinas´s Summa Theologiae. He researchs the possibility of upbringing for love, and from what point of view this education is needed. The author concludes that the concept of love is quite different in the Summa Theologiae. In the context of Aquinian ethics, virtue points out that friendly love, as a unique phenomenon of human beings, is not necessary and therefore not only permits but also requires it to be developed through education.
The problems of humanising technological education
Authors: Kulyk Yevgen , Kulyk Yuriy
Published: January 2020

It is contended that technological education, forming the outlook of the modern- -day person should accord to universal human values (the good, love, harmony, aesthetics, etc.). The achievements of scientific and technological advance should be subordinate to these values. It is argued that humanising the training of technology teachers requires a strategy and the establishment of regular courses in culture for technology teachers. It is suggested that humanising the paradigm of education changes the basic requirements of the dialectical method in revealing the contradictions of the object of study. Key ideas of pedagogy focus onthe uniqueness of each student and take into account her/his interests and values. This may require individualising the learning process. The abovementioned issues can be responded to through a cultural approach to technology teachers’ training. The content of courses should recognise the integrity of the cultural experience of humanity: ethical, religious, philosophical, aesthetic, technical, professional, etc., in addition to the scientific way of knowing the world. The use of technology in everyday life has greatly increased. There has been a shift of cultural patterns from the realm of mass consciousness and mass behaviour that operate on a natural basis to new patterns characterised by individualisation, analysis, and even consciousness transformation and construction. Therefore, teaching that the technological culture of self-determination is culturally determined must be included in the cultural training of technologyteachers.
Visible Learning and educational policies in New Zealand and Australia
Authors: Sarbiewska Anna
Published: January 2020

This article analyses the theoretical background of changes that have taken place over the last two decades in the Australian and New Zealander educational systems. That background has two elements: first, understanding of pedagogical activities performed by the teacher and students in the educational process has been modified, second, Hattie’s concept of Visible Learning has gained a following. The text consists of four sections. The first section presents a reconstruction of the traditional model of perceiving the actions of teaching and learning. In the second section an insight into the foundations of an innovative, evidence-based approach to education is provided. The following section describes the concept of Visible Learning in relation to the main determining factors of education. Finally, the last section describes some of innovations introduced in New Zealand’s and Australia’s educational systems which, it is argued, raise the effectiveness of educational practices there.
Fractional Occupation Numbers and SIC-Scaling Methods with the Fermi-Lowdin Orbital SIC Approach
Authors: Aquino Fredy W. , Shinde Ravindra , Wong Bryan
Published: January 2020

We derive an alternate expression for the Fermi-Lowdin Orbital Self-Interaction Correction (FLO-SIC) energy gradient and re-visit how the FLO-SIC methodology can be seen as a constrained unitary transformation acting on canonical Kohn-Sham orbitals. We present a new performance and accuracy analysis of the FLO-SIC approach, which we have recently implemented in the massively-parallelized NWChem quantum chemistry software package. Our FLO-SIC implementation has been tested for the prediction of total energies, atomization energies, and ionization potentials of small molecules and relatively large aromatic systems. The ionization potentials of multi-electron systems are calculated with the adaptation of fractional occupation numbers within FLO-SIC. We also carefully examine the possible improvements of these predictions with various SIC scaling methods based on kinetic energy densities and gradients of electronic densities.

Authors: Krauklis Andrejs
Published: January 2020

Various polymers were tested for leaching of ions via High Resolution Induced Coupled Plasma Mass Spectrometry (HR-ICP-MS) in order to determine which coating materials for the pushing rod are compatible with the glass fiber stress-corrosion setup. The biggest concern is the leaching of Si ions, and is compared among various commercially available polymers - four different polyurethanes, polyvinylchloride, poly(methylmethacrylate) and silicone. Significant amounts of other elements leached were also noted and reported.
Low Temperature Calorimetry Coupled with Molecular Simulations for an In-Depth Characterization of the Guest-Dependent Compliant Behaviour of MOFs

Published: January 2020

In this study adsorption microcalorimetry is employed to monitor the adsorption of four probes (argon, oxygen, nitrogen and carbon monoxide) on a highly flexible mesoporous metal-organic framework (DUT-49, DUT = Dresden University of Technology), precisely measuring the differential enthalpy of adsorption alongside high-resolution isotherms. This experimental approach combined with force field Monte Carlo simulations reveals distinct pore filling adsorption behaviours for the selected probes, with argon and oxygen showing abrupt adsorption in the open pore form of DUT-49, in contrast with the gradual filling for nitrogen and carbon monoxide. A complex structural transition behaviour of DUT-49 observed upon nitrogen adsorption is elucidated through an isotherm deconvolution in order to quantify the fraction of the open pore, contracted pore and intermediate pore forms that coexists at a given gas pressure. Finally, the heat flow measured during the guest-induced structural contraction of DUT-49 allowed an exploration of complex open-contracted pore transition energetics, leading to a first assessment of the energy required to induce this spectacular structural change.
WHY SHOULD WE SPEAK ABOUT A COMPLEMENTARITY OF SENSE AND REFERENCE?

Published: January 2020

Until around 1800, Western philosophy believed that there were two types of conception in the world: the mental and the physical. Hence the extensive discussions about the analytical and synthetic knowledge that dominated the philosophy of Kant, the greatest Enlightenment philosopher. However, from the Peircean studies, the discussion about the conceptions has expanded, giving rise to the complementarity, which currently addresses the conceptions of extension and intensionof logic and philosophy. In the educational context it is often claimed that mathematics is a language, since it provides both a means of communication and a substantiation of our thoughts. As a result, mathematical fluidity is now considered the most important. From this perspective, the pedagogical principles underlying mathematics teaching become similar to those used in language teaching. But mathematics is not mere language. Language is a wonderful instrument of the human spirit, yet it serves logic, poetics, and rhetoric far better than mathematics. Thus, this article aims to show that the approach of elementary mathematics education must consist in teaching to read a term beyond its correspondence between letters and sounds, and also to permit the understanding how a skill set can be worked completely in abstract in relation to content. The semiotic methodology is utilized as input to analyze what is really the mathematics.

Attempts of braze welding galvanized steel with a trifocal multi-beam laser system
Authors: Górka Jacek , Kciuk Monika , Figzał Emil
Published: January 2020

The paper presents the evaluation of the brazing capabilities of the multi-beam Trifocal laser joint system made of galvanized steel DX51D with a thickness of 3 mm, covered with a protective coating of Magnelis type. The brazed joints obtained have been subjected to metallographic, strength and corrosion resistance tests in the Ascott CCIP450 salt cell. The tests have shown that there is a certain range of brazing process parameters that allow to make the correct overlap joints of high quality with small welding distortions and a narrow heat affected zone. The obtained joints are characterized by a slightly worse corrosion resistance than the basic material, and zinc evaporation by means of additional low-power laser beams improves the solder's flow.

Objetivo. La aproximación al diagnóstico de sangrado agudo (SA) manifestado con síntomas inespecíficos, utilizando el hematocrito como laboratorio de apoyo es un reto en la Sala de Emergencias (SE). Se compararon las capacidades operativas del hematocrito y radio plaqueta/hematocrito (PLHER) para discriminar pacientes con SA.
Métodos. Con un diseño de precisión diagnóstica, se compararon pacientes con y sin SA atendidos en la SE de la Clínica del Occidente S.A. durante el 2017. El espectro de enfermedad (EDx) incluyó controles negativos[grupo_0], población general con o sin trauma ortopédico cerrado[grupos_1-2], pacientes con trauma ortopédico cerrado [grupo_3], con SA ginecológico [grupo_4], SA gastrointestinal [grupo_5] y controles positivos [grupos_6-7]. Se compararon las capacidades operativas del PLHER y hematocrito para discriminar pacientes con SA.
Resultados. 655 pacientes fueron seleccionados, principalmente hombres. No hubo diferencias entre las medianas de hematocrito del grupo_0 con los grupos 1-2; comparado con el grupo 0, la mediana del PLHER fue mayor en todos los grupos del EDx. (p:<0.05). Con los puntos de corte ≥6.037 y ≥6.348 el AUC del PLHER para discriminar pacientes con posible SA [grupos 1-3] o cualquier grupo del EDx [grupos 1-7] fue 0.709 y 0.766, respectivamente. Los AUC del hematocrito para discriminar pacientes con posible SA o cualquier grupo del EDx fueron 0.682 y 0.755, respectivamente.
Discusión. El PLHER presentó mejores capacidades operativas que el hematocrito para discriminar pacientes con SA. Podría ser útil para identificar pacientes con SA atendidos con signos y síntomas inespecíficos en la SE.
Desempenho na estimativa de precipitação pelo radar meteorológico do oeste de Santa Catarina
Authors: José Murilo Fretta , Minuzzi Rosandro Boligon
Published: January 2020

Apesar da sua eficiência, o radar meteorológico apresenta erros que são sensíveis às calibrações e às físicas envolvidas nos sistemas naturais. O objetivo neste estudo foi analisar o desempenho na estimativa de precipitação pelo radar meteorológico do oeste (RMO) de Santa Catarina em diferentes escalas de tempo. No período de 6 outubro de 2017 à 31 de janeiro de 2018, foram comparados dados de precipitação acumulados (> 1 mm) em 10 minutos, 60 minutos e 24 horas por nove estações pluviométricas com as estimadas pelo radar. A avaliação da estimativa de precipitação pelo RMO foi realizada por meio do coeficiente de correlação, o Erro Médio, o Erro Padrão de Estimativa, os Índices de Concordância e de Confiança e pela Eficiência de Nash-Sutcliffe. Para os acumulados em 24 horas e 60 minutos o radar tende a superestimar a precipitação em média de 5,82 mm e 1,62 mm, com um desempenho considerado ‘muito bom’ e ‘mediano’, respectivamente. Para a precipitação de 10 minutos os resultados foram diversificados e com um desempenho ‘ruim’. Como o desempenho do radar tende a diminuir quanto menor a escala de tempo de estimativa de precipitação a calibração do RMO se faz necessário.  Performance in precipitation estimation by meteorological radar in the West of Santa Catarina A B S T R A C TDespite its efficiency, weather radar has errors that are sensitive to the calibrations and physics involved in natural systems. The objective of this study was to analyze the performance in the estimation of precipitation by the Meteorological Radar of the West (MRW) of Santa Catarina at different time scales. In the period from October 6, 2017 to January 31, 2018, accumulated precipitation data (> 1 mm) were compared in 10 minutes, 60 minutes and 24 hours for nine rainfall stations with those estimated by radar. The MRW estimation of precipitation was performed using the correlation coefficient, the Mean Error, the Standard Error of Estimation, the Concordance and Confidence Indexes, and the Nash-Sutcliffe Efficiency. For the accumulated in 24 hours and 60 minutes the radar tends to overestimate the average precipitation of 5,82 mm and 1,62 mm, with a performance considered 'very good' and 'medium', respectively. For the 10 minute rainfall the results were diverse and with 'poor' performance. As the radar performance tends to decrease the lower the time scale of precipitation estimation the MRW calibration becomes necessary.Keywords: calibration, remote sensing, hidrological station.
Repercussão da Exploração Hidroelétrica no Funcionamento Geoecológico de Paisagens Fluviais Amazônicas
Authors: De Paula Eder Mileno Silva
Published: January 2020

A exploração hidroelétrica promove impactos naturais e sociais irreversíveis, também observados nas bacias hidrográficas amazônicas que receberam as Usinas Hidrelétricas de Balbina, Tucuruí e Samuel. A Usina Hidrelétrica de Belo Monte (UHEBM) está sendo construída desde 2011 no Baixo Curso do Rio Xingu e começou a produzir energia elétrica no ano de 2016. Os barramentos construídos para UHEBM impactam na dinâmica do fluxo fluvial de energia, matéria e informação do Rio Xingu, com desdobramentos negativos para o meio biótico, abiótico e para as comunidades indígenas, ribeirinhas e urbanas locais. Nesta pesquisa teve-se objetivo de analisar as consequências da exploração hidroelétrica no funcionamento das paisagens fluviais no Baixo Rio Xingu, através de análises geossistêmicas dos componentes das paisagens. Analisou-se o funcionamento antes do início do represamento da água (1985 a 2014) e após o represamento do Xingu (2016 a 2019). As conclusões indicam como se dá o funcionamento geoecológico de rios amazônicos explorados por hidrelétricas, especificamente aqueles com trechos de vazão reduzida. Essas conclusões podem contribuir no planejamento e gestão ambiental de paisagens fluviais e ajustes na operação da UHE Belo Monte. Repercussion of Hydrielectric Exploration in the Geoecolocical Performance of Amazon Fluvian Landscapes   ABSTRACT  Hydroelectric exploitation promotes irreversible natural and social impacts, also observed in the Amazonian basins that received the hydroelectric plants of Balbina, Tucuruí, and Samuel. The Belo Monte Hydroelectric Power Plant (UHEBM) is in construction since 2011 in the low-lying region of the Xingu River and started producing electricity in the year 2016. The dams built for the UHEBM impact on the dynamics of the river flow of energy, matter and information on the river Xingu with negative consequences for the biotic and abiotic environment, and for the indigenous, riverside and urban communities. The research’s objective was to analyze the consequences of hydroelectric exploitation on the river landscape in the lower Xingu River through geosystemic analysis of landscape components. The operation was analyzed in the period before the beginning of the water dam (1985 to 2014) and after (2016 to 2019) the damming of Xingu. The conclusions indicate the geoecological functioning of Amazonian rivers explored by hydroelectric plants, specifically those with reduced flow stretches, and these conclusions can contribute to the planning and environmental management of river landscapes and adjustments in the operation of the Belo Monte Hydroelectric Power Plant. Keywords: Belo Monte, Volta Grande do Xingu, Hydrogeography, Fluvial Geomorphology.
Métodos baseados em temperatura do ar para estimativa de radiação solar incidente diária no Estado do Rio de Janeiro

Published: January 2020

A radiação solar global (Rs) é um parâmetro de entrada necessária para estimativa da evapotranspiração e em modelos de crescimento, desenvolvimento e simulação do rendimento das culturas. Em locais com ausência de dados de Rs, podem ser utilizados métodos empíricos em função dos extremos de temperatura do ar para sua estimativa. No estado do Rio de Janeiro, estudos sobre Rs com base em métodos empíricos são escassos. Portanto, o objetivo foi estimar Rs diária com base no método de Hargreaves-Samani (HS) por meio de dados da amplitude térmica diária de 11 estações meteorológicas automáticas na escala bianual (2013-2014). O desempenho do método HS com o coeficiente proposto por Hargreaves (1994) e calibrado por Allen (1995) foi avaliado com indicadores estatísticos. O coeficiente R² variou entre 0,30 a 0,85, seguido do índice d entre 0,58 a 0,95 e do índice c entre 0,32 a 0,87, classificados como “Péssimo” a “Ótimo”. O erro absoluto variou de -6,23 a 7,09 MJ m-2 d-1 e o RQME 2,98 entre 8,69 MJ m-2 d-1. Baseado nos resultados o coeficiente proposto por Hargreaves (1994) resulta em estimativas precisas em comparação ao calibrado por Allen (1995), com ressalva das estações costeiras.  Methods based on air temperature to estimate daily incident solar radiation in Rio de Janeiro State A B S T R A C TGlobal solar radiation (Rs) is a necessary input parameter for estimating evapotranspiration and in crop growth, development and simulation models. In places with no data of Rs, empirical methods may be used as a function of the extremes of air temperature for their estimation. In the state of Rio de Janeiro, studies on Rs based on empirical methods are scarce. Therefore, the objective was to estimate daily Rs based on the Hargreaves-Samani (HS) method using data from the daily thermal amplitude of 11 automatic meteorological stations on a biannual scale (2013-2014). The performance of the HS method with the coefficient proposed by Hargreaves (1994) and calibrated by Allen (1995) was evaluated with statistical indicators. The R² coefficient ranged from 0.3 to 0.85, followed by the d index between 0.58 to 0.95 and the c index between 0.32 to 0.87, classified as "Poor" to "Great." The médium erro ranged from -6.23 to 7.09 MJ m-2 d-1 and RMSE 2.98 to 8.69 MJ m-2 d-1. Based on the results, the coefficient proposed by Hargreaves (1994) results in more accurate estimates compared to the one calibrated by Allen (1995), with the exception of the coastal stations.Keywords: meteorological parameters, atmospheric transmissivity, thermal amplitude.
Assumptions vs the reality – a case study on developing writing in a foreign language at the level of early school education in Poland and Lithuania
Authors: Budzyńska Paula , Mazlaveckiene Gerda
Published: January 2020

The study aims at providing a potential answer to the question about the extent to which selected currently available ELTs for early school education in Poland and Lithuania allow developing pupils’ writing skills in English described in the most recent academic studies and official regulations at both European (e.g. the CEFR Volume Companion) and national level (e.g. the Core Curriculain the countries in question). The analysis of selected ELTs is performed with the use of a model created by the authors and based on the scientific background and the aforementioned documents. The study demonstrates changes that should be introduced to the content of the examined textbooks in order to make them possibly the most compliant with researchers’ stands and valid recommendations, for instance, (1) it would apparently be beneficial to diversify the types of writing activities included in the chosen ELTs, and (2) pupils could significantly benefit from introducing to the analysed textbooks more writing activities referring to their experience.

The paper’s focus is on the Belarusian State Pedagogical University students’ addressing the heritage of the Polish pedagogue Janusz Korczak. Described are common readers’ strategies used by students in the process of learning and marginal textual tactics creating the possibilities of diversification of readers’ practices in class. The condition for such kind of transformation is Korczak’s specific design of pedagogical statement which enables him to act as a “screen” for students to project and implement their pedagogical experiences.
Głosy współczesnych dzieci w sprawie "Kajtusia Czarodzieja" – śladem Korczakowskiego pisarskiego eksperymentu

Janusz Korczak engaged children in writing novels intended for them. His writing experiments consisted in directly transferring children’s ideas to the paper, correcting and reworking the stories under the influence of the listeners’ comments, removing and cutting fragments of the text at their request. Following Korczak’s method, a reconstruction of understanding by modern children of created 85 years ago novel “Kajtuś Czarodziej” was made. Based on focus interviews, it was established that the fairytale context of reading is read by children on a multithreaded basis, filtered by reference to the present day, critically evaluated by older children. The linguistic layer is acceptable, while the transfer of the fairytale aspect to real life does not suit the contemporary young recipients. The children’s suggestions regarding the new plots of reading were mainly of mimetic character in relation to the original.
Wyjść poza krąg. O przywracaniu pedagogiki Marii Rogowskiej-Falskiej i Wiery Schmidt
Authors: Siegień Wojciech
Published: January 2020

In the article, based on theoretical assumptions about framing mechanisms taken from the work of Georg Lakoff and the Polish tradition of post-dependence research, the author conducts a comparative analysis of cases of reframing the hegemonic and strongly patriarchal narratives regarding the pedagogical legacy of Janusz Korczak and Ivan Jermakov. As a result of systemic changes after 1989, narratives so far suppressed have come to the fore. It applies to minority voices, especially female voices. The comparative analysis took into account the voices of female educators from Poland and the Soviet Union – Maria Rogowska-Falska and Vera Schmidt. The main questions concern how hegemonic pedagogical discourses may erode and whether the processes of redefining pedagogical thought in Poland are analogous to trends in other countries of Central and Eastern Europe? The study points to far-reaching analogies of the processes of reframing in Poland and Russia. This has its consequences for our understanding of the achievements of Janusz Korczak in Poland and the roots of psychoanalysis in the Soviet Union.
Korczaka i współczesnych pedagogów ulicy koncepcja uwspólniania świata jako inspiracja podejść partycypacyjno-rozwojowych w pracy z dziećmi ulicy
Authors: Sokołowska Jolanta
Published: January 2020

Janusz Korczak has his unique contribution to the development of work with street children. The purpose of this text is an attempt to answer the question: what has Korczak in common with people who are working with the category of abandoned, neglected children nowadays? To what extent his views, developed over a hundred years ago, are an inspiration for educators taking up work in the street space today? To answer these questions I will refer both to Korczak’s thoughts contained in his works as well as to the texts created by contemporary educators. The analyses confirm that the common feature of the described projects is the concept of sharing the world. Both Korczak and pedagogues of the street situate themselves close to the children’s community, participating in their everyday life. Both pedagogues and Korczak refer to a similar concept of the child, focusing primarily on the child’s potential. They try to get to know the child’s living conditions and by understanding its habitus they aim to take actions appropriate to child’s abilities, avoiding elements of symbolic violence.

El trabajo enfoca el aprovechamiento de las semillas de maracuyá Passiflora edulis f. flavicarpa Deg. con aplicación en el diseño de un producto cosmético: crema exfoliante con aceite de semillas de maracuyá y residuo sólido generado de la extracción del aceite. La metodología aplicada para la formulación de la crema consistió inicialmente en la extracción del aceite de las semillas por solventes orgánicos, éter etílico y por metodología mecánica a través del prensado. Las variables físico-químicas de análisis evaluadas en la crema exfoliante fueron el pH, la extensibilidad y la capacidad de emulsión; entre las propiedades físicas se evaluó el color, olor, brillo, arenosidad y ausencia de grumos como indicadores macroscópicos de una adecuada distribución del tamaño de la partícula y de una textura uniforme. Se concluyó que el aceite de las semillas de maracuyá, por su composición en elementos proteicos y lipídicos, conservan de manera óptima las propiedades inherentes a un producto diseñado para el cuidado y acondicionamiento de la piel. Esta alternativa de uso, proveniente de material que para las industrias primarias es un residuo no aprovechable, representa una alternativa en la gama de materias primas semielaboradas con propiedades que agregan valor a productos para el consumo humano.

Pre-stack seismic inversion based on a genetic algorithm: A case from the llanos basin (Colombia) in the absence of well information
Authors: Moncayo Edward , Tchegliakova Nadejda , Montes Luis
Published: January 2020

The Llanos basin is the most prolific of the Colombian basins; however few stratigraphic plays have been explored due to the uncertainty in determining the lithology of the channels. Inside a migrated 2D section, a wide channel was identified inside a prospective sandy unit of the Carbonera Formation, composed by intercalations of sand and shale levels, and considered a main reservoir in this part of the basin. However, the lithology filling the channel was unknown due to the absence of wells. To infer the channel lithology, and diminish the prospective risk a model based pre-stack seismic inversion was proposed.However, without well logs available along the line, the uncertain initial model diminishes reliance on the inversion. To circumvent this impasse, a seismic inversion with a genetic algorithm was proposed. The algorithm was tested on synthetic seismograms and real data from an area of the basin, where well logs were available. The error analysis between the expected and the inverted results, in both scenarios, pointed out a good algorithmic performance. Then, the algorithm was applied to the pre stack data of the 2D line where the channel had been identified.According to the inverted results and rock physics analysis of wells near the seismic line with comparative geology, classified the channel was described as to be filled by silt, shale and probably some levels of shaly sands, increasing the exploratory risk because this lithology has low porosity and permeability, contrary to the producing reservoirs in neighbor fields, characterized by clean sands of high porosity. The algorithm is useful in areas with few or no borehole logs.
A kinetic study of esterification of naphthenic acids from a Colombian Heavy Crude Oil
Authors: Quiroga-Becerra Haydée
Published: January 2020

This article presents the kinetic study of the esterification reaction of naphthenic acids from a Colombian heavy crude oil, with a Total Acid Number (TAN) of 7,33 mgKOH/g, in a batch type reactor. Temperature was changed between 150 - 250°C while the ratio moles of methanol per mole of carboxylic groups, remained constant in 20:1. The reaction time was varied from 0 - 600 minutes. Reduction in the concentration of naphthenic acids in the reactor is determined by the measurement of Number Total Acid (TAN), ASTM D 664. Naphthenic acids were extracted from the crude and structurally characterized by Fourier Transform Infrared Spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR) and Gel Permeation Chromatography (GPC).

The esterified oil was analyzed by FTIR, to identify the variation of the main functional groups. After determining the activation energy, frequency factor and, reaction order, a kinetic law was proposed for the esterification of naphthenic acids in Colombian heavy oil. Finally, it was evaluated the effect of esterification of naphthenic acids on the corrosion of steel ASTM A106 Gr.B. The corrosion of steel was reduced from 34,16 to 3,08 mils per year, (mpy), after esterification of naphthenic acids.

In this article, the flame speed values determined experimentally for laminar premixed flames of the vapors of two biofuels in air are presented. The laminar flame speed is a fundamental thermochemical property of fuels, and is essential for analyzing the flame propagation in practical devices, even those employing turbulent flames. The fuels obtained from transesterification of soy and canola oils are tested. Also, the diesel flames are studied to serve as a baseline for comparison. The experiments are performed with a tubular burner; pre-vaporized fuel is mixed with hot air and is ignited. The flame speed is determined at fuel-equivalence ratios of 1; 1,1 and 1,2 by recording the geometry of the flame. The experimental results show that the flame speed of biofuels is lower by about 15% than that of diesel. Also, the maximum value of flame speed is obtained at an equivalence ratio of approximately 1,1.
