Outcome of Pregnancy and Labour in a Patient with Hodgkin’s Lymphoma (Clinical Case)
Authors: Borscheva A. A. , Pertseva G. M.
Published: September 2019

Background. Hodgkin’s lymphoma (HL) is a malignant disease of lymphoid tissue, which is characterised by the appearance of giant Reed—Berezovsky—Sternberg cells in the lymph nodes affected by the pathological process. These cells can be detected through microscopic examination. Currently, HL is one of the most treatable oncological diseases. In recent years, the recovery rate in patients suffering from this pathology has increased (70–90%), almost reaching the recovery rate in patients starting treatment at the early stages. Given the above, the quality of life in these patients during remission is becoming more important, since most of them are women of childbearing age planning to have children. In this connection, it is of great importance to study the course of pregnancy and labour, along with their effect on the possibility of a relapse, in such patients.

Aim. In this paper, we set out to analyse the course of pregnancy and childbirth in a patient suffering from HL.

Materials and methods. We studied the medical records (including medical history and pregnancy records) of a patient whose pregnancy occurred in the setting of a severe oncological pathology – HL in remission. The patient underwent a thorough examination and the baby was successfully delivered.

Result. The outcome of pregnancy and childbirth for the patient and foetus was studied in the setting of a severe oncological pathology (HL in remission).

Conclusion. The pregnancy of a woman suffering from a serious oncological pathology (HL in remission) was prolonged to full-term and successfully completed. The patient was able to experience the joy of motherhood for the third time.
Central Part of the Auditory Analyser in Children with Type 1 Diabetes
Authors: Lazareva L. A. , Tarasenko A. A. , Chernyak I. Yu.
Published: September 2019

Aim. The present article assesses the state of the central part of the auditory analyser in children with type 1 diabetes.

Materials and methods. The study included 71 children with type 1 diabetes mellitus who were treated at the Endocrinology Department of the Children’s Territorial Clinical Hospital from September 2017 to February 2018. The children’s age ranged from 7 to 15 years (8±2.6). Group A comprised 34 children who were fi rst diagnosed with type 1 diabetes, with the duration of clinical manifestations not exceeding 3 months; whereas group B included 37 children who had been suffering from type 1 diabetes for 1–5 years. The control group was represented by 30 children of the same age group without a somatic pathology (group K). The functional state of the central part of the auditory analyser was assessed when studying brainstem evoked potentials of short, middle and long latency.

Results. In the course of studying short-latency brainstem evoked potentials at a broadband-click stimulus frequency of 10 Hz and an intensity of 70 dB, the latent periods of peaks and peak-topeak intervals were analysed in groups A, B and K. Statistically signifi cant differences were observed for I and V latent periods of peaks, as well as for the I–V inter-peak interval. At a click stimulus intensity of 70 dB, peaks and peak-to-peak intervals of middle-latency brainstem evoked potentials revealed differences in the values of NO, PO, Na, Pa and NO–PO between the groups of patients with type 1 diabetes and the control group. Greater statistical differences, as compared to the control group, were observed in the latent periods of long-latency brainstem evoked potentials for interval P1 in group A and intervals P2 and N2 in group B (unfavourable course) during 100 dB stimulation at a repetition frequency of 1 Hz in a time window of 50 ms. The presence of differences between groups A and B in the parameters of peak P2 (p ≤ 0.07), as well as peak intervals P2–N2, N1–N2, N1–P1, N2–P2 and N1–P2, may indicate signifi cant differences in the centres of the auditory analyser (p ≤ 0.1). At the same time, the maximum activity of the studied parameters was found in the group of patients with newly diagnosed type 1 diabetes.

Conclusions. The study of different types of brainstem evoked potentials, characterising the central parts of the auditory analyser, in children with type 1 diabetes allowed the authors to register functional disorders both in the brainstem segment and in the cortical structures. This fact indirectly indicates initial manifestations of diabetic neuropathy in the studied category of patients and can be used in the future for diagnosing CNS disorders.

Published: September 2019

Aim. The paper analyses the dynamics and structure of forensic medical examinations conducted by an expert panel in cases involving medical malpractice in the Krasnodar Krai (2010– 2018).

Materials and methods. The authors studied the annual reports along with the archived copies of expert panel reports on the cases of medical malpractice submitted in 2010–2018 by the Department for Complex and Expert Panel Examinations (Bureau for Forensic Medical Examination, Krasnodar). The obtained results were processed using Microsoft Excel 2010 and SPSS Statistics Data Editor v.17.0. In this study, the authors employed the following methods: retrospective, comparative and analytical.

Results. In 2010–2018, a total of 1,023 expert panel examinations were conducted in cases involving medical malpractice. A steady increase in the number of examinations (from 36 in 2010 to 245 in 2018) is associated with the growing number of citizens complaining about the poor quality of medical care, the interest of judicial and investigation authorities in looking into such offences, etc. A direct cause-and-effect relationship between imperfect and erroneous healthcare delivery and ensuing adverse effects was established in 212 cases, whereas indirect or no relationship was determined in 130 and 644 cases, respectively. The number of examinations pertaining to criminal cases amounted to 29.1%, showing an increase by 3.5 times (from 16 in 2010 to 57 in 2018); while the number of examinations related to civil cases and those conducted during pre-investigation checks came to 18.2% and 52.7%, respectively.

Conclusion. The study shows a steady increase in the number of examinations related to medical malpractice (including criminal cases), which reveal a direct cause-and-effect relationship between errors in healthcare delivery and clinical outcomes

Raramente poderia se contar a história de um Estado-nação a partir de um objeto tão singularcomo um prédio. Entretanto, argumentamos que a história do Narkomfin se confunde com ahistória da Rússia. Uma vez concebido como a forma-tipo da habitação soviética e destinado acontrapor-se de forma absoluta ao modo de vida capitalista, este prédio construtivistaconstruído em 1930 tornou-se, após um processo de restauração iniciado em 2017, uma“habitação de classe premium” e um dos metros quadrados mais caros do distrito financeiro deMoscou. Utilizando o caso do Narkomfin como dado empírico, refletimos, neste presenteartigo, sobre as transformações históricas que ocorreram na Rússia no decorrer do século XX enas primeiras décadas do século XXI: da gênese da política urbanística moderna à gestação docampo arquitetônico soviético; da era stalinista ao colapso da URSS; da consolidação de umaeconomia de mercado de transição ao capitalismo neonacionalista de Vladimir Putin.Finalizamos traçando algumas conclusões acerca da relação entre políticas econômicas,políticas de imagem e políticas de memória, assim como a conexão entre a gênese de camposarquitetônicos e o desenvolvimento de políticas de gestão do patrimônio cultural.

O O Consumo Cultural de Jovens na Cultura Hallyu
Authors: Santana Aline Gomes , Santos Salett Tauk
Published: September 2019

O artigo investiga o processo de hibridização cultural vivenciado por jovens universitários no consumo da cultura de origem sul-coreana denominado hallyu. A perspectiva teórica correlaciona a teoria de hibridização discutida por García Canclini, com as ideias de Bauman sobre modernidade; e o perfil da juventude contemporânea proposto por Martín-Barbero. A partir da observação do comportamento dos jovens, em suas interações sociais no campo real e virtual e suas manifestações de consumo, buscamos compreender porque estes indivíduos, ancorados nas tecnologias da informação e comunicação - TICs, buscam referências na hallyu, para reconverter suas práticas culturais orientando suas identidades. A abordagem metodológica utiliza, além de pesquisa bibliográfica, técnicas de observação direta, entrevista semiestruturada e a netnografia para coletar informações nos sites e redes sociais, visto ser a internet um espaço de interação privilegiado pelos indivíduos observados.
A Sociedade do Consumo e o Movimento de Vanguarda
Authors: Oliveira Bianka Rodrigues de , MARINHO THAIS ALVES
Published: September 2019

Este artigo busca analisar as relações entre o Movimento Tropicália, entendido aqui como expressão do neotribalismo de Maffesoli, e a sociedade de consumo. A hipótese é de que a constituição identitária, inspirada pelo conceito de illusio de Bourdieu, aciona necessidades de autocategorizações ontológicas, não supridas pela lógica do capitalismo moderno, e por isso, gera uma tendência para formação de tribos urbanas, que passam a orientar o consumo dos membros destes grupos.
Origem, forma e conteúdo da expressão artística:
Authors: Lins Artur André
Published: September 2019

Na fronteira da história da arte com a antropologia cultural, o proposta desse ensaio almeja promover o encontro das ideias de Aby Warburg com as de Franz Boas. O mote para a costura teória desse autores é exatamente o problema da origem da expressão artística, ressaltando, para tanto, questões relativas à forma e conteúdo. Observamos que, por um lado, a origem da expressão artística encontra explicação pela ancestralidade dos hábitos motrizes, na fabricação técnica dos objetos da vida cotidiana, cuja necessidade psicológica se acha no prazer do virtuose em dominar formas compelxas. Por outro lado, a origem da expressão artística funda-se na ordenação cosmológica do mundo, no efeito de vinculação simbólica, cuja necessidade psicológica se exerce pela empatia mimética que visa apreender o imponderável da existência.
Fechamento e abertura
Authors: Freitas Carolina Rodrigues
Published: September 2019

Este ensaio é uma busca por reler Simmel (2005), em especial a ideia de moldura, desenvolvida pelo autor em referência ao processo de individuação moderno, à luz de argumentos como os de Bazin (2018) sobre a moldura filmíca, de Deleuze e Guatarri (2007) sobre o enquadramento e de Michael Hardt (2007) sobre os afetos. Acredita-se que isso pode nos ajudar a compreender Simmel como uma forma sensível aos limites do sujeito moderno, e que, de certa maneira, antecipa uma percepção do potencial de outros modos de individuação, como aqueles pensados, muitos anos depois, por autores como Foucault (1984; 1985), Deleuze (1992) e Maffesoli (2006).

Investigation of the center coordinates of a circle with unknown radius using polar measurements
Authors: İNCE Hüseyin , ERDEM Nuri
Published: September 2019

Circular pools or buildings may be encountered in production of maps for making development plans, in the first facility cadaster and on land. Geodetic measurements may be made on at least three different points of the circleshaped pool or building to obtain positions in a coordinate system of measurement points with a geodetic ground-based electronic tachometer after connection to another polygon. It is possible to get a circle from these three points where the coordinates can be calculated, the coordinates of the center of the circle and the radius of the circle with the help of drawing programs (Netcad, Carto CAD, GEOCAD ...). In drawing programs related to cartography, the details of passing the circle from three points, the coordinates of the center of the circle and the radius of the circle cannot be accessed because the details are kept proprietary by software companies. We have been curious about how the coordinates of the center of the circle or the radius of the circle in question are calculated by using the subprograms on a computer. Apart from the information hidden by software companies, two studies which are indirectly close to the subject mentioned in the application have been identified with respect to the solution of the problem on the computer. However, it was found that these studies did not directly illuminate our research topic, so, this issue should be investigated. This study presents theoretical solutions for the topic, makes numerical implementations and provides findings and interpretations.
Investigation of Black Sea mean sea level variability by singular spectrum analysis
Authors: BEŞEL Cansu , TANIR KAYIKÇI Emine
Published: September 2019

The mean sea level has been continuously increasing since the end of the 19th century and will continue to increase in the 21st century. The Intergovernmental Panel on Climate Change (IPCC) states that the sea level will rise by 40-60 cm until 2100. This situation will lead to social and economic problems, especially in coastal areas. For this reason, studies on sea level determination have great importance in our country. In this paper, we used the singular spectrum analysis (SSA) to investigate mean sea level variability along the coasts of the Black Sea, which is an intercontinental inland sea. This study aimed to determine the trend in sea level change along the coasts of the Black Sea over time. The mean sea level data from 10 tide gauge stations (Amasra, Batumi, Bourgas, Constantza, Igneada, Poti, Sevastapol, Trabzon II, Tuapse and Varna) are analyzed in this study. The mean sea level data were obtained from the Permanent Service for Mean Sea Level (PSMSL). SSA was applied to the mean sea level observations at tide gauges stations, and the results were interpreted. According to the analysis results, there are increasing trends at the Batumi, Poti, Tuapse, Constantza, Sevastopol and Varna stations. The obtained trend of Bourgas station is not significant. There is The results of the Amasra, Igneada and Trabzon II tide gauge stations were inadequate in interpreting any change. There were no trends at these stations. Close eigenvalues were computed from the mean sea level at the tide gauge stations. This situation shows that there is a dominant seasonal component in the time series.

Authors: Sampaio Caio , Ramos Juliana Penariol , Maciel Ivana Maria Esteves
Published: September 2019

A área odontológica vem sendo abordada constantemente pela mídia, seja direta ou indiretamente, e isso é esperado, considerando-se que a odontologia não foge do contexto social. O fato é como e quais informações os veículos de comunicação vêm emitindo, e também como a sociedade vem absorvendo essas informações. Considerando esses fatores, o presente estudo traz uma revisão de literatura que objetivou agregar os pontos de representatividade social da odontologia sob a visão da mídia, além de identificar possíveis resultados desta abordagem para o contexto social da profissão odontológica e consequências sobre a perspectiva de promoção de saúde e relação profissional-paciente. Esta revisão constatou que a veiculação pela mídia de elementos relacionados à odontologia necessita de vários avanços, visto que os paradigmas que tangem a imagem do profissional odontológico acarreta danos no cenário de promoção de saúde bucal, sendo desfavorável tanto para a sociedade quanto para a classe odontológica.

Published: September 2019

The aim of this research was to determine the influence of the metallic materials characteristics on the dynamics of a car crash. Another important aspect is that the metallic parts are sometimes repaired after minor accidents and this fact influence strongly the mechanical characteristics and their influence on the dynamics of a car crash. In this paper, we analyze the mechanical characteristics of thin steel plates repaired by local heating associated with plastic deformation (similar to hot working) and cold straightening (similar to local cold working) for automotive side and door panels made of structural steel. Thin sheet plates, 0.9mm thickness, were deformed by impact and repaired by local heating using the flame and induction heating then plastically deformed while hot as well as straightened without heating. The heat repaired samples were studied by light microscopy to determine microstructure change and samples were tensile tested to determine their mechanical characteristics. Local excessive grain growth generates anisotropy, the assembly behaves as a composite material with regions that show significant plastic deformations while others little or no deformations at all. Without procedures adjusted to each material repairs involving heating are to be avoided, cold working should be employed when replacement is not possible.

Published: September 2019

In the work experimental results on the manufacture of glass foam with high mechanical strength from glass waste are presented. By replacing the usual conventional energy source with a nonconventional energy (electromagnetic waves) the heating efficiency allows a fast and economical manufacturing process. Calcium carbonate as a foaming agent and an addition of sodium silicate (aqueous solution) as a binder were used. By their physico-mechanical and morphological features (0.40-0.66 g/ cm3 the apparent density, 0.054-0113 W/ m·K the thermal conductivity, 2.2-6.3 MPa the compressive strength, below 1.2 % the water absorption and under 2 mm the pore size), the foams are appropriate for their use as replacer of existing similar building materials on the market.

El propósito del presente estudio es establecer si la aplicación de la inyección de agua de baja salinidad (LSW) es efectiva para las condiciones de reservorio y de fluido de la arenisca U Inferior del Campo Paka Norte del B15. Además, busca evaluar la rentabilidad que podría generar un proyecto con esta técnica de recuperación mejorada de petróleo.Para el desarrollo de este proyecto se consideró un flujo de trabajo con el objetivo de procesar y validar la información, construir el modelo dinámico, realizar el ajuste histórico de presión y producción, generar varios casos pronóstico y su respectivo estudio económico.Se estimó un valor de Petróleo Original en Sitio de 79 millones de barriles. La producción del caso base señala que el campo produciría 7,49 millones de barriles de petróleo hasta el año 2028 con un factor de recobro de 10,56%. Los esce-narios de producción señalaron que, en el mejor de los casos, se podría duplicar la producción acumulada y alcanzar un factor de recobro cercano al 20%. Los casos de baja salinidad en general mostraron factores de recobro adicionales de entre 0,5 a 0,6% con respecto a los mismos casos, pero de alta salinidad. El análisis económico determinó que, en todos los escenarios analizados, la inyección de agua de baja salinidad presentaba mayores VAN y TIR, con menores PRI.

Este estudio presenta los resultados de laboratorio de la inyección de solvente en muestras obtenidas del reservorio M-2, campo petrolífero VHR de la región amazónica ecuatoriana. El objetivo fue determinar el aumento del factor de recuperación en núcleos saturados con aceite de 29.2 °API. Este estudio consistió en tres etapas: en la primera etapa, varios métodos EOR que potencialmente pueden aplicarse a núcleos, que se obtuvo de la arenisca M-2, fueron analizados. En la segunda etapa, se realizó un desplazamiento de petróleo utilizando agua de formación, este resultado se usó como punto de referencia. En la tercera etapa, se procedió a desplazar el petróleo con solvente y se comparó con el resultado de la segunda etapa. Para la segunda y tercera etapa, se desarrolló un modelo simple basado en la teoría de Buckley-Leverett. Este modelo ayudó a cuantificar el aumento en el factor de recuperación. Los criterios de selección determinaron que las condiciones eran apropiadas para la inyección de solvente. El punto de referencia dio un factor de recuperación del 25.7%. Por otro lado, el aceite desplazado después de usar solvente fue de 43.77%. Este resultado significa un aumento del 18.07% en el factor de recuperación. El método numérico dio un factor de recuperación de 49.97%, que es 6.2% más alto que los valores experimentales. El experimento permitió concluir que la opción de inyectar solvente es muy práctica para usarlo en un proyecto piloto para el reservorio M-2 del campo VHR de la región amazónica ecuatoriana.

Published: September 2019

El presente trabajo explica los esfuerzos actuales para desarrollar una tecnología accesible, rentable y limpia para el aprovechamiento de residuos lignocelulósicos para la obtención de etanol y otros derivados mediante procesos fermentativos de los diferentes azúcares y subproductos que resultan de la degradación de la celulosa. La biomasa, cuyo principal componente es la celulosa, es la materia prima más abundante del planeta, y su aprovechamiento racional produciría enormes beneficios económicos y ecológicos. La hidrólisis ácida de la celulosa es costosa y contaminante. Por lo tanto, se intenta llevar a escala industrial la hidrólisis enzimática, mediante enzimas producidas por varias especies de hongos (Trichoderma, Aspergillus, etc.), bacterias y otros organismos, y buscando otras fuentes industrialmente útiles para una biorrefinería. Es ecológicamente beneficiosa, y potencialmente mucho más económica, pero es necesario reproducir a escala industrial la actividad observada en laboratorio. La ingeniería genética ayuda a diversificar la producción de enzimas o aumentar la cantidad producida por los organismos. La hidrólisis enzimática completa usa enzimas celulolíticas: endoglucanasas, exoglucanasas y ß-glucosidasas, difícilmente producidas en cantidades industrialmente interesantes por un solo organismo, siendo necesario combinar varios de ellos. Además, técnicas como reciclaje o recirculación de enzimas dentro del biorreactor ayudarían a un aprovechamiento integral. Otra línea de investigación es la modelación matemática de la producción de los crudos enzimáticos con simuladores como Superpro Designer y otros. La gran variedad de productos obtenidos a partir de biomasa vegetal, desde etanol hasta ácido cítrico, ácido láctico, ácidos urónicos, ácido acético, etc., respaldan los beneficios económicos, sociales, industriales y ecológicos que generaría esta tecnología.

Published: September 2019

El hormigón, mezcla de cemento Portland, agua, y agregados, es comúnmente utilizado en la industria de la construcción con un alto porcentaje de fabricación in-situ. Las proporciones de cada uno de los componentes de la mezcla es de mucha importancia para asegurar la calidad producto (esfuerzo de compresión). Actualmente, varios métodos empíricos para el diseño de mezclas de hormigón son utilizados; sin embargo, éstos son basados en su mayoría en ecuaciones, tablas y/o correlaciones, sin considerarse experiencias pasadas y/o datos experimentales. El presente estudio ilustra la aplicación de la teoría de lógica difusa para desarrollar un modelo que permite estimar las proporciones de los componentes del hormigón al peso, sin utilizar aditivo. Las variables independientes (datos de entrada) seleccionadas fueron las que comúnmente se usan para diseño de mezclas. Datos históricos experimentales y la experiencia del técnico de hormigón fue empleada para la construcción de las funciones de membresía (FMs) y las reglas difusas. El sistema de inferencia lógico (SIL) Mamdani fue escogido para construir el modelo en razón de que éste permite trabajar con varias salidas (relación agua – cemento y agregados). Los resultados indican que el SIL es capaz de estimar las proporciones de una mezcla de hormigón de manera aceptable (R2=95.1%); sin embargo, el modelo se lo puede mejorar a medida que se disponga de mayor conocimiento del sistema. Además, el modelo puede hacer uso de la información que reposa en archivos y las experiencias personales de los técnicos para la elaboración de modelos particulares para cada proyecto.

La presente investigación utilizó un diseño experimental completamente al azar (DCA), con 3 tratamientos (T1, T2 y T3) y un blanco (TB) como referencia, cada uno con 3 repeticiones, con un total de 12 pilas de compost, ubicadas en la parroquia de Amaguaña. Cada pila estuvo contenia 132 Kg de estiércol y contenido ruminal provenientes del camal de faenamiento familia Aldaz; 30 gdeurea, 4L de melaza y 4Kg de aserrín; se inocularon para el tratamiento T1 con 30 x 109 UFC de Proteus mirabilis, T2 con 30 x 109 UFC de Citrobacter freundii, T3 con 356 x 103 células Penicillium spp. y TB sin adición de microorganismos. Se tomaron mediciones de temperatura, pH y humedad a los 3 días de creación de las pilas (tiempo de adaptación de microorganismos a su nuevo hábitat). El análisis de varianza (ANOVA), determinó que no existieron diferencias estadísticamente significativas entre tratamientos, por ello para seleccionar el mejor tratamiento se emplearon indicadores cuantitativos y cualitativos. Como resultado T2 fue el mejor tratamiento con una reducción en la cantidad de desechos orgánicos del 80,97%; una Tmáx de 46 oC, materia orgánica del 80,02%, produciendo un sustrato orgánico marrón oscuro altamente salino con pH 9,04, nitrógeno total (4%), fósforo total (0,02%), potasio (0,73%) y libre de patógenos fecales.

que provoca afectaciones del tipo social, ambiental y económico para la zona. Una solución es el uso de tecnosoles que son suelos propios de lugar a los cuales se les adiciona elementos ajenos para mejorar su capacidad de remoción de un contaminante específico, sin embargo, este estudio se basó únicamente en la modificación del suelo de Chone mediante su calcinación y así simular un tecnosol capaz de remover fosfatos en soluciones acuosas mediante su calcinación, proceso que provoca un cambio en las propiedades físicas y químicas al tiempo de volatilizar los compuestos orgánicos presentes. Para esto, se realizó una disolución con concentración de 1.25 mg/L de fosfato monobásico de potasio, semejante a la concentración presente en el río. Las concentraciones del adsorbato contenidas en el agua ya filtrada a través del suelo modificado fueron medidas con espectrofotómetro en 4 sesiones continuas a intervalos de 2 horas, la máxima adsorción fue del 92% al cabo de 7 horas de filtrado; la cinética de la adsorción estuvo dada por una reacción de primer orden, además, se obtuvo un mejor ajuste con la isoterma de Langmuir que representó una adsorción en monocapa de fosfatos. Se modeló el comportamiento de la adsorción del fosfato en software libre con el que se estimó un tiempo de saturación del adsorbente de 14 horas. Como conclusiones del trabajo se tiene que los valores de adsorción de fosfatos son mayores con el suelo modificado (92%) que con el suelo natural (40.05%); la calcinación del suelo proporcionó una reactividad de los compuestos férricos presentes en el adsorbente con un incremento de su área superficial, intercambio catiónico y por ende una mayor adsorción del contaminante.
Arquitectura estructural y estratigráfica de la secuencia pre-aptiense de la cuenca oriente ecuatoriana

Published: September 2019

La configuración estructural y estratigráfica de la secuencia pre-Aptiense en la Cuenca del Oriente, se deriva del desarrollo de dos eventos tectónicos superpuestos. El primero pertenece a la aparición de un régimen extensional durante el Jurásico Medio-Va­langiniense, representado por depresiones de hemi-graben y graben que constituyen los tres dominios tectónicos de la cuenca. En el graben Sacha-Shushufindi, el relleno sedimentario son representados por sedimentos volcaniclásticos continentales de la Formación Chapiza, parcialmente contemporáneos con la actividad del arco volcánico Jurásico Misahuallí (Tschopp, 1953), que se desarrolla en el margen occidental de la cuenca. Probablemente, la extensión está vinculada a los períodos de retroceso de un slab que se evidencia por el desarrollo de una zona de subducción y un control extensional en la región de arco posterior. El segundo episodio representa la inversión de fallas normales a inversas producidas a partir de una tectónica de compresión, lo que resulta en mega estructuras positivas (Anticlines Sacha y Shushufindi). La edad de la inversión podría estar relacionada con la época volcánica Hauteriviense de la Formación Chapiza Superior o Miembro Yaupi, que se desarrollan en una sola operación contra la estructura invertida de Sacha.
