Authors: Wei Xiaoyao , Lin Tao , Duan Min , Du Hengli , Yin Xuefeng
Published: May 2021

Liquid crystals (LC) have been found to have many unique characteristics during the last few decades. The liquid crystal phase is ubiquitous in the biological world, as well as in cellulose and its derivatives. Cellulose nanocrystals (CNC), which can obtain the chiral LC phase in aqueous suspension, have been attracting much attention. The unique size and properties of CNC, such as their light weight, special optical properties, non-toxicity, and biocompatibility, etc., have made them widely applicable in diverse fields. This brief literature review introduces the relationship between the LC phase and CNC. Advantages of CNC as a liquid crystal forming material and the preparation of CNC are discussed. The left-handed cholesteric phase structure and the corresponding unique optical properties of CNC-based LC are described in detail. The CNC-based LC aqueous suspension and three stages of forming LC phase are also described. Then, the main reasons accounting for the brittleness and non-uniformity of pristine CNC-based LC are summarized, as well as ways to overcome these problems. Finally, some optical applications of CNC-based LC films in anti-counterfeiting, colorimetric sensors, and composite devices are considered.
Computational design of 3D-printed active lattice structures for reversible shape morphing
Authors: Lumpe Thomas S. , Shea Kristina
Published: May 2021

Active structures can adapt to varying environmental conditions and functional requirements by changing their shapes and properties, which makes them suitable for applications in changing environments as found in aerospace and automotive. Of special interest are light and stiff structures with shape morphing capabilities, which is naturally contradictory. Existing concepts in literature can be limited to a single, non-reversible actuation and are difficult to design due to the inherent complexity of large-scale lattices with many elements and complex target deformations. Here, we show how 3D-printed active materials can be combined with an efficient computational framework to design large-scale lattice structures that can change their shape between an initial state and a target state. The reversible deformation is controlled by a single actuation input and heating of the structure. Numerical and experimental results show the generality of the proposed method and the applicability to different problems such as morphing airfoils.

Injury is the leading cause of death among children and adolescents, with about 10% of injuries being penetrating. Penetrating injuries that occur if a child falls or sits down on a long, sharp object are rare by their mechanism. So far we have experience in treating 5 children with penetrating injuries to the abdominal organs involving long sharp objects. 3 children were injured by falling on a metal fence, and the other 2 by sitting down on a metal pin and a scythe. The consequences of the injuries were damage to the small intestine (1), colon (4), stomach (1), kidney (1), urinary bladder (2). Clinical cases. Two brothers, aged 11 and 12, who fell out of a tree on a metal fence from a height of about 3 meters, were brought Pediatric Municipal Clinical Hospital of Poltava Municipal Council with metal rods in their bodies. After preoperative preparation, the children were operated on. Removal of the foreign objects was performed in the operating room. One of the boys was found to have damage to the stomach, transverse colon, kidney crushing. Suturing of wounds of hollow organs, and nephrectomy were performed. The second boy was found to have damage to the rectum, a colostomy was performed with its subsequent closure. A 16-year-old girl was injured when she sat down on a vertical scythe blade. During the operation, wounds of the ileum and mesentery of the hungry intestine were revealed, the wounds were sutured. All children were discharged after they recovered. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: penetrating abdominal trauma, children.

Meckel’s diverticulum (DM) is a formation of the ileum caused by incomplete obliteration of the omphalomesenteric duct in the developing embryo. This is one of the most common anomalies of the digestive tract in children. Most DM develops completely asymptomatically. Clinical symptoms develop in only 16% of cases, and 50–60% of them are children under 10 years, an average of 2.5 years of age. The severity of clinical symptoms in DM is associated with the development of complications: intestinal bleeding, intestinal obstruction (intussusception, strangulation intestinal obstruction), diverticulitis with perforation and peritonitis, etc. The article presents a clinical case of adhesive intestinal obstruction in an 8-year-old, which occurred after DM in the anamnesis. As the adhesive intestinal obstruction is an extremely rare complication of DM in children, the presence of patients with acute surgical pathology of the abdominal cavity requires pediatric surgeons to clearly understand the occurrence of such complications in the perspective of the development of intestinal tube defect – DM and the need for the immediate radical treatment tactics in the event of this problem. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: children, Meckel’s diverticulum, complications, adhesive intestinal obstruction.

Gastrointestinal foreign bodies in children are a common reason for emergency surgical care. Among the foreign bodies of the digestive tract, special attention should be paid to neodymium magnets, known for their strong magnetic abilities and high resistance to demagnetization. The usual age of hospitalized children with intestinal magnetic bodies is 2–4 years. Swallowing neodymium balls can be accompanied with perforation, fistula, intestinal obstruction, peritonitis, shot bowel syndrome; septic condition with fatalities. The article presents a clinical case of swallowing 17 magnets by two-years-old boy for a long time. The child was hospitalized without anamnestic date of foreign bodies to the digestive tract. Intestinal magnets were diagnosed radiological. Early surgery with gentle tactics was used. The child recovered. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. The authors declare no conflicts of interests. Key words: foreign bodies of digestive tract, perforation, magnets.

Early neonatal sepsis mainly has bacterial etiology – 84%, less often fungal – 12%, otherwise – viral and parasitic etiology. According to the European Center for Disease Control and Prevention (CDC), the occurrence of sepsis in newborns is closely related to birth weight and gestational age, as well as skin color. It was established, in particular, that the most severe types of sepsis occur in children weighing 400–1500 g at birth and less than 30 weeks of gestation. Parasitic sepsis in newborns refers to severe forms of childhood sepsis, with mortality reaching high. The article presents the experience of successful treatment of 2 newborns in a maternity hospital both were non-transportable. At the beginning of treatment, the anamnesis of pregnancy was thoroughly studied. From the first day of the disease, both patients underwent a comprehensive instrumental (ultrasound, X-ray) and laboratory (PCR, ELISA, procalcitonin, coagulogram, CRP and general biochemistry tests) examinations. One child – prematurely born at 30 weeks of gestation with a weight of 1070 grams – was treated for intrauterine chlamydial sepsis. The second suffered from intrauterine toxoplasmotic sepsis and Rhconflict; the latter was treated in utero at 30 weeks of gestation. Both patients were treated by a multidisciplinary team and the children recovered. Conclusions. The results of treatment show effectiveness pathogen approach to the treatment of severe sepsis in newborns. The research was carried out in accordance with the principles of the Declaration of Helsinki. The permission of the parents of the children was obtained to conduct the research.

El protagonismo de Hispania en la consolidación de la Primacía Petrina. A propósito de dos libros recientes
Authors: Acerbi Silvia
Published: May 2021

En el presente artículo se aborda el análisis crítico de dos libros recientes, de naturaleza y formato muy diferentes, desde la perspectiva común del Primado universal del obispo de Roma. La obra de A. Ferreiro se propone demostrar que en la Hispania romana y visigoda el primado pontificio fue aceptado desde los siglos III al VII sin gran oposición por el episcopado hispano, aunque no faltaran momentos de fricción. En el libro de J. Vilella, un estudio prosopográfico de la figura de Osio de Córdoba, se resalta el protagonismo del obispo hispano en el concilio de Sárdica del 343 considerado como el primer paso hacia la ruptura de las Iglesias de Oriente y Occidente.

With no right to have rights. Conflict analysis and the common rights of the townsfolk of Rymanów in the latter half of the 19th century
Authors:   Dr, University of Warsaw, Faculty of History, Department of 19th Century History, Poland, Popek Joachim
Published: May 2021

This article concentrates on an inquest held by the local commission in Sanok into the common rights claimed by the inhabitants of the town of Rymanów in the latter half of the 19th century. The negotiations, which commenced in 1859, sometimes took a heated turn. They were attended by much conflict and misunderstanding, equally between the manor and the town as among the townsfolk themselves. Conclusions drawn from the analysis of the archive source provided the basis on which to evaluate the activities of each of the parties – the town’s agents and the landlords – and, interestingly, those of the commissioners and other officials in the public administration, whose decisions exhibited bias. The townsfolk began the negotiation from a position of certainty and conviction of the legal force of Prince Czartoryski’s privilege granting the disputed common rights to them. The manor’s agent, on the other hand, took a bold position, which he consistently maintained. He disputed the authenticity of Czartoryski’s grant and even the fact that the Prince had ever held the manor. This approach ultimately proved successful. Attention is also drawn to the role played by local commissioners and the officials in the National Commission in Lviv, the latter making the most important decisions. The first phase demonstrates the commissioners’ influence on the original outcome. The rationale given for the second decision, on the other hand, shows the arbitrariness with which the Lviv Commission made its ruling, based on just one official document. Analysis of the proceedings highlights a more general trend prevalent in Galicia, first described in the example of Rymanów. This is a case in which two consecutive inquests in the same matter ultimately ended in a negative decision. In other words, the townsfolk’s claims were dismissed, and they were denied any common rights eligible for buyout or regulation.

Protocol has long been considered to be the set of international courtesy rules primarily rooted from the French and Spanish royal courts of the 16–18th century. It has recently become a means of subconscious persuasion not only in diplomacy but also in the business and social world. These long-established rules facilitate not only the official representatives of nations but also for their people their co-existence in peace and harmony. It creates space, and sets the framework where offline and online interactions may take place. One of the most significant instruments that makes complex and delicate mechanisms of foreign policy work successfully. The year of 2020 brought many changes we all must face and react to. Protocol itself and protocol professionals are not exempt. Meetings, delegation programs, conferences and all official and social engagements have become unconventional to the end. The rise of online and hybrid events demands the skill of adaptability both in international relations and in protocol. The present article aims to briefly examine protocol by definitions and to show its complexity from a scientific perspective. Protocol as applied interdisciplinary science: an innovative approach initiated by a professional expert having elaborate practical experience in the field.

Authors: Bregola Allan Gustavo , Ottaviani Ana Carolina , Luchesi Bruna Moretti , Pavarini Sofia Cristina Iost
Published: May 2021

ABSTRACT Objective: Despite the greater vulnerability of care providers, the literature shows that their mortality rate is considerably lower compared to care recipients. The aim of the present study was to analyze the mortality rates of community-dwelling older adults who provided support in activities of daily living (ADL) (group PC) and older adults who received in activities of daily living (group RC) in a four-year period considering the effects of age, sex and schooling in both groups and stress in in group PC. Methods: 261 older adults PC and 279 older adults RC participated in the study. In 2014, we collected data on demographic characteristics and functioning. In 2018, the participants were contacted a second time and information on deaths was obtained. The mortality rate was calculated for each group. Results: Death cases in four years were considerably higher among the group who were receiving support. The mortality rate was 12.6% in the PC group and 31.2% in the RC group. In deceased PC, 69% presented with high-perceived stress in baseline. About half of the PC were independent, whereas the RC group exhibited some functional dependence in 2014. There was no association between risk factors in the group PC, however the female sex was marginally associated with the risk of mortality among the RC (HR: 1.7 [95% CI: 0.9-3.0]). Conclusion: Some demographic characteristics have been considered risk factors for the mortality of the old age population, however these were not confirmed in this study among the older adults who provided and received care.
Aproximación dialógica a las necesidades formativas para perfeccionar la práctica de la extensión rural con campesinos en Caldas, Colombia
Authors: Sastoque Marlon Javier Méndez , Restrepo Evangelina Giraldo
Published: May 2021

Resumen: Definir en qué capacitar a los extensionistas rurales es una preocupación constante para quienes asumen esta labor formativa. Tarea de la que derivan múltiples propuestas, de cuya elaboración suelen estar ausentes los propios extensionistas rurales, a pesar del conocimiento vivencial que los autoriza para pronunciarse sobre ello. Bajo esta premisa, con la intención de posicionar un tipo de extensión fundada en la acción dialógica entre extensionistas y campesinos, el estudio responde al siguiente cuestionamiento: a lo luz de lo pensado, expuesto y experimentado por los propios extensionistas rurales, en aras de avanzar hacia el perfeccionamiento de su práctica profesional con campesinos, ¿cuáles son hoy sus necesidades formativas? A partir del diálogo con 59 extensionistas que prestan sus servicios a productores campesinos en Caldas, Colombia, recurriendo al análisis de discurso, se identificaron las siguientes categorías formativas: a) formación para la comunicación efectiva, b) formación para la práctica en contexto, y c) formación para la práctica interdisciplinaria e integral. Se concluye que escuchar la voz de los extensionistas rurales, dándoles protagonismo en la definición localizada de sus principales necesidades formativas, es una vía para el posterior diseño de planes de capacitación cada vez más próximos a las exigencias de la realidad afrontada.

ABSTRACT Objective: to assess skills, satisfaction, self-confidence and experience with debriefing of nursing professionals in a simulated scenario for hospital admission of patients with COVID-19. Method: this is a quantitative, observational, cross-sectional study, carried out at a university hospital with nursing professionals. Data were collected in June 2020 using the following instruments: sociodemographic questionnaire, checklist for assessing patient admission skills, the Student Satisfaction and Self-Confidence in Learning Scale and the Debriefing Experience Scale. Subsequently, the collected data were analyzed using descriptive and analytical statistics. Results: sixty-two professionals participated, 23 (37.10%) nurses and 39 (62.90%) nursing technicians, with an average age of 36.82 (±6.19). Compliance with patient admission skills ranged from 66.13% to 90.32%. The overall average score on the Student Satisfaction and Self-Confidence in Learning Scale was 4.46 (± 0.36) and, on the Debriefing Experience Scale and factors, 4.63 (±0.33). Professionals who updated themselves with scientific articles and protocols obtained a higher average score on both scales (p<0.05). Conclusion: most professionals demonstrated skills on patient admission, satisfaction with learning, self-confidence in the simulated scenario and adequate experience with debriefing.

Authors: MATTA Reinalda Melo da , RAMOS Denise Gimenez
Published: May 2021

Abstract This study aims to investigate the effect of Sandplay Therapy on the treatment of children who are victims of mistreatment with internalizing and/or externalizing behavioral problems. Method: The Child Behavior Check List instrument was applied to all children between 6 years 6 months and 10 years 11 months from 24 institutions. All of them presented clinical and/or borderline levels of behavior concern. The institutions where the children would compose a control group, those where they would receive Sandplay Therapy treatment (experimental group), and those where they would receive Placebo treatment were determined by drawing lot. The same instrument was applied after the treatments, or 20 weeks; in the experimental group, a test was applied after six months. The results show that the children in the experimental group showed significant improvements. These changes remained six months after the end of therapy and were verified by analyzing Sandplay scenarios.
WE CAN DO IT!: DISCURSOS SOBRE A FORÇA DA MULHER NAS MOVÊNCIAS DA HISTÓRIA
Authors: Gonzaga Juliane de Araujo
Published: May 2021

Resumo Este artigo analisa os discursos produzidos pelo célebre cartaz de fundo amarelo que traz a imagem de uma mulher operária com a legenda We can do it!. Criado na Segunda Guerra Mundial e repetido pelos feminismos dos anos 1980 e 2010, o cartaz produz discursos que se relacionam com distintas conjunturas históricas. O estudo objetiva analisar os discursos sobre a força da mulher, materializados pelo enunciado verbo-visual, para compreender como as condições de possibilidade históricas motivam a enunciação da capacidade feminina em épocas distintas. Este trabalho se inscreve no campo da Análise do Discurso filiada a Michel Foucault, que investiga as práticas discursivas e a formação de objetos e subjetividades. Assim, mobiliza os conceitos foucaultianos de enunciado, arquivo e acontecimento. A análise demonstra que as condições de retorno da imagem promovem transformações nas regras de formação desses discursos. Logo, as descontinuidades históricas determinam as repetições desse enunciado como acontecimentos únicos e singulares.

Learning to Unlearn, and then Relearn: Thinking about Teacher Education within the COVID-19 Pandemic Crisis
Authors: Fernandes Alessandra Coutinho , Gattolin Sandra Regina Buttros
Published: May 2021

ABSTRACT For decades now, in the context of teacher education, we have been discussing the importance of paying attention to the fast and profound changes both in society and in people’s personal lives, as a consequence of the widespread use of new digital technologies. Yet, not much has changed in schools, where traditional teaching still rules. Students continue to be more knowledge consumers than active knowledge producers; besides, the use of technology for educational purposes remains as either a threat or an unattainable goal. However, the COVID-19 pandemic has compelled educational institutions to rethink the role of technology in education. In this article, we comment on the crisis that has struck higher education and how it has set our institutions and ourselves, as professors and teacher educators, into a deep process of rethinking our past practices and reimagining our future.

Published: May 2021

ABSTRACT In this article, we problematize literacy issues in the current context of instability and uncertainties generated by the Covid-19 pandemic, from its social, political and educational impacts. Our discussion will focus on fictional vignettes that we composed based on real stories circulating in the media and social networks, and marked (but not restricted to) by the intense use of digital technologies. Our aim is to formulate questions about the relationship among society, literacy, technology and education, which have been of primary concern to us as teachers and researchers of languages and literacy. We do not intend to offer definitive answers or solutions, but only to suggest research paths for studies in literacy and Applied Linguistics, in light of concepts such as multiplicity, emotions, rhizome and nomadic thought.

A republican plated denarius from Aquincum
Authors: Juhász Lajos
Published: May 2021

A puzzling plated republican denarius was found decades ago in the civil town of Aquincum. Due to its worn state its identification was troublesome, but it turned out to be an imitation of M. Furius’ coin minted in 119 BC. It is unique for Aquincum, and also quite rare in Pannonia, which raises a number of questions. Even more perplexing are the two mountings on the obverse, which served to fasten the coin to some other object. It is unfortunately impossible to tell, when and why this 2nd century BC plated denarius appeared in the 2–3rd centuries AD civil town.

Boys Becoming Men. Male initiation rites in a North-Eastern Nigerian village
Authors: Galántha Márta
Published: May 2021

The Chadic-speaking Fali of the southern Mandara Mountains live in well-organised, compact villages of thousands on both sides of the Nigeria-Cameroon border. They are subsistence sorghum farmers whose communal and personal existence depends on having several children and a good annual harvest. Unsurprisingly, these two existential facts determine both the fundamental values and much of the daily life of the Fali. An examination of the biennial initiation cycle and its main rites also reveals that, at the ritual level, these manifest a symbolic equivalence to the developmental cycle of their staple crop, sorghum, and are attuned intime to the agricultural cycle. In my presentation at the IX. MΩMΟΣ conference (Miskolc, 2015) I described in detail, and showed pictures of the 2007 Fimbidi rite (Figs 6–13), the greatest of the initiation rituals of the Jilvu Fali. In this short paper I intend to overview the main characteristics of the whole of the Jilvu male initiation cycle, drawing attention to the complicated web of social relationships, underlying beliefs, personal and communal ambitions behind the rites. Although this picture cannot be but sketchy, I hope it will nonetheless be of interest to archaeologists.This presentation is derived from my husband’s, anthropologist James H. Wade’s early work among the Falifrom the 1970’s onwards, and our joint fieldwork from the 1990’s to 2010. The accompanying pictures, like those of my 2015 presentation, were taken by him.

GEOGRAPHICAL COMPONENT OF RETROSPECTIVES OF DEVELOPMENT OF THE TERRITORY OF IVANYCHI DISTRICT OF VOLYN REGION
Authors: Melnik Oleg , Melniichuk Mikhailo
Published: May 2021

Aim. The aim of the study is to analyze the retrospective of the development of Ivanychi district as a significant factor influencing the state of the environment.

Method. The scientific work used such methods of geographical research as: historical, comparative-geographical, cartographic, mathematical, observation, generalization, analysis and synthesis. Using the statistical method, the indicators of different development of the territory of Ivanychi district by types of nature management are calculated. The method of geoinformation modeling allowed to build maps of grouping of settlements of the district according to historical mentions and significance in the settlement retrospective.

Results. An ecological and geographical assessment of the historical stages of development of the territory of Ivanychi district of Volyn region by types of nature management in one or another epoch of human civilization development has been carried out. It is noted that during this time the basis of the economic complex of the district were agriculture and various industries using natural raw materials. The structure of management on the territory of the region underwent a radical change in the post-war period of the twentieth century, when coal mining deposits of the Lviv-Volyn coal basin were put into operation. The negative impact on the environment from economic activity in the area, the types of which together exert a strong man-made pressure on all components of the geographical shell.

The scientific novelty lies in the ecological and geographical determination of the magnitude of the impact of economic nature in the Ivanychi district of Volyn region on the environment and the analysis of the formation of the settlement structure during the historical retrospective.

Practical importance. The results of the research can be used in the educational process of VSU named after Lesya Ukrainka in teaching geographical, economic and tourism disciplines. The results will find their application in the legislative and executive work of local governments in the development of programs of socio-economic development of territorial communities. The materials of the research will promote the rational use of anthropogenic resources and objects of social and household services in Volyn, which will allow to qualitatively influence the course of administrative reform. A number of provisions can be used in similar studies of the regions of Ukraine.
ACTUAL PROBLEMS OF MILITARY TOURISM DEVELOPMENT IN UKRAINE UNDER COVID-19 PANDEMIC CONDITIONS
Authors: Smyrnov Igor , Tsui Jibo
Published: May 2021

The aim of the study is to reveal the problems of development of the tourist potential of military tourism in Ukraine in modern conditions, including the influence of the Covid-19 pandemic.

Research methodology. It consists first of all in finding analysis and generalization of materials of relevant sources in both Ukrainian and foreign languages (English, Polish). The method of comparison is also used, in particular in the characterization of the tourist potential of the Arpad Line and the Molotov Line. Statistical methods were used in the preparation of tables.

Results. The research reflects, first, the potential tourist resource of the period of Kamianets-Podilskyi's stay in the status of the capital of the United Ukrainian State (UPR and WUPR) during the liberation struggles of 1917-1920; secondly, the tourist potential of World War II defense facilities on the example of the Arpad Line (which was built by the Hungarians but is now in Ukraine) and the Molotov Line (which was built by the USSR in the then territory of Ukraine, but is now in Poland); thirdly, the impact of the Covid-19 pandemic on the development of the restaurant business as a component of the tourism industry in Ukraine, Kyiv and other cities.

Scientific novelty. It consists in characterizing the resource potential of military tourism on the example of Kamianets-Podilskyi, as the capital of United Ukraine during the liberation struggle in 1917-1920, as well as in performing a comparative characteristic of the Arpad Line and the Molotov Line as a resource bases for military tourism development in Ukraine. and neighboring countries (Poland, Hungary). This material is considered in connection with the impact of the Covid-19 pandemic on tourism, in particular on the restaurant industry.

Practical significance. Implemented through the characterization of events and objects of military history of Ukraine for the development of military tourism as its resource base and more active use in domestic and cross-border tourism exchange, in particular under the Covid-19 pandemic influence. The practical significance of the article is directly related to the development of tourism in Kamianets-Podilskyi, where it is recommended by us to more actively use the past of this city as the capital of the United Ukraine during the liberation struggle for tourism development in the city and Podillya region, in particular in excursion activities (new excursions on relevant topics), military-historical reconstructions and games, etc. with appropriate marketing and advertising support. The same can be recommended in the case of tourist use of the Arpad Line in Ukraine (for Ukrainian, Hungarian and tourists from other countries) and the Molotov Line (to intensify the Ukrainian-Polish tourist trans-border exchange).

A Nonparametric Hawkes Model for Forecasting California Seismicity
Authors: Gordon Joshua Seth , Fox Eric Warren , Schoenberg Frederic Paik
Published: May 2021

A variety of nonparametric models have been proposed for estimating earthquake triggering. We investigate the ability of the model-independent stochastic declustering method developed by Marsan and Lengliné (2008) to estimate variable spatial triggering that can vary with direction, magnitude, and region. We develop an approach for local fault estimation and demonstrate forecasting methods that use the nonparametric estimates. Simulation studies are conducted to verify the effectiveness of the method, and the nonparametric estimates are applied to a California earthquake catalog. Model forecast performance is evaluated retrospectively by comparing our models with the long-term forecast of Helmstetter et al. (2007), using both deviance and Voronoi residuals. We show improved performance compared with Helmstetter et al. (2007) in various regions while using a full nonparametric estimation and forecasting approach.

Published: May 2021

Strong ground-motion records are the primary input data in earthquake engineering studies to improve understanding of seismic hazard and risk. As the overseer of the Iran Strong Motion Network (i1-net), the Road, Housing, and Urban Development Research Center occupies the leading position in this field in the country. With more than 1260 active accelerometers and a collection of over 14,129 earthquake recordings since 1973, the Iran Strong Motion Network is the major Iranian source of information for engineering seismology and earthquake engineering. The present article describes the current status and developments of the i1-net in the last 46 yr.
Probabilistic Forecasting of Hydraulic Fracturing-Induced Seismicity Using an Injection-Rate Driven ETAS Model
Authors: Mancini Simone , Werner Maximilian Jonas , Segou Margarita , Baptie Brian
Published: May 2021

The development of robust forecasts of human-induced seismicity is highly desirable to mitigate the effects of disturbing or damaging earthquakes. We assess the performance of a well-established statistical model, the epidemic-type aftershock sequence (ETAS) model, with a catalog of ∼93,000 microearthquakes observed at the Preston New Road (PNR, United Kingdom) unconventional shale gas site during, and after hydraulic fracturing of the PNR-1z and PNR-2 wells. Because ETAS was developed for slower loading rate tectonic seismicity, to account for seismicity caused by pressurized fluid, we also generate three modified ETAS with background rates proportional to injection rates. We find that (1) the standard ETAS captures low seismicity between and after injections but is outperformed by the modified model during high-seismicity periods, and (2) the injection-rate driven ETAS substantially improves when the forecast is calibrated on sleeve-specific pumping data. We finally forecast out-of-sample the PNR-2 seismicity using the average response to injection observed at PNR-1z, achieving better predictive skills than the in-sample standard ETAS. The insights from this study contribute toward producing informative seismicity forecasts for real-time decision making and risk mitigation techniques during unconventional shale gas development.
