CRM Well Interference Models for Evaluating Reservoir Filtration and Volumetric Properties from Production Data
Authors: Афанаскин И. В. , Крыганов П. В. , Глушаков А. А. , Ялов П. В.
Published: August 2021

В работе предложены две CRM-модели, описывающие интерференцию скважин. Модели получены путем комбинации уравнения материального баланса и уравнения притока. В первой модели рассматривается общий для всех скважин поровый объем пласта. Во второй модели все скважины имеют индивидуальные поровые объемы, между которыми происходят перетоки. На синтетических примерах показано, что для бесконечного пласта можно применять первую модель, а для ограниченного пласта лучшие результаты дает вторая модель.

The study proposes two CRM models that simulate well interference. The models combine the material balance equation and the inflow equation. The first model considers the reservoir pore volume common to all wells. The second model uses individual pore volumes to each well with interconnecting flows. The simulated examples show that the first model applies to infinite reservoirs while the second model gives the best results for limited reservoirs.

В статье предлагается организационный подход к цифровизации бизнес-процессов би-модальным разделением на уровень бизнеса и на уровень ИТ, которые не объединяются в единые команды, а, напротив, разделяются с целью дать возможность бизнес-аналитикам и владельцам процессов развивать бизнес-приложения с помощью лоукод платформы в режиме реального времени и в стратегии органического роста. Уровень ИТ подключается только для развития платформы путём классических подходов.

The study solves the problem of circuit routing in ICs. We propose a multistage approach based on interconnection mesh reduction. It expands the chip interconnecting capability by introducing extra channels. The interconnection mesh reduction significantly accelerates the existing routing algorithms. The introduction of more channels makes it possible to reduce the routing problem in a complex interconnect space topology by removing the new routes from the extra (virtual) channels.

Процесс цифровизации образования, активно проводимый в нашей стране и по всему миру, позволил более широко применить в учебном процессе современные приемы преподавания, перенося часть педагогической нагрузки с очного формата на дистанционный. Проектируемые и используемые цифровые образовательные платформы уже сейчас включают в себя не только оцифрованный лекционный видеоматериал и электронные формы учебников, но и элементы автоматизации проверки выполненных учащимися заданий. Расширение области применения автоматической проверки решенных учащимися задач и выполненных упражнений является объективной необходимостью, в противном случае при дистанционных формах образовательного процесса резко возрастает нагрузка на педагога, который должен выделять значительное время на проверку увеличившегося самостоятельной работы школьников и студентов. Кроме того, при дистанционном преподавании снижается эффект личного присутствия педагога, когда учитель и ученики разделены экранами компьютеров. Существенной помощью может стать использование интеллектуальных помощников преподавателя и автоматизированных систем проверки, построенных методами машинного обучения и технологии нейронных сетей. В настоящей статье рассмотрены подходы к решению поставленных задач по автоматической проверке графических заданий и выявлению заимствований в текстовом виде. Показаны возможные варианты реализации этих функций с использованием технологий искусственного интеллекта.

The digitalization of education in Russia and worldwide enables a more extensive introduction of advanced teaching methods through a partial switch from offline to online teaching. The existing and coming e-learning platforms feature not only digital lecture videos and e-textbooks, but some automated assessment/grading tools. There is a need to expand the coverage of such tools to avoid the extreme burden of online teaching as the educator has to allocate significant time for assessing the increased amount of high school/university student assignments. Also, distant learning diminishes the effect of the educator personal presence since the teacher and the student are separated by their computer screens. Smart educator assistants and automated assessment tools based on machine learning and neural networks can significantly alleviate the problem. This study offers some strategies for automated assessment of graphic assignments and checks for plagiarism. Possible AI-based implementations of such features are presented.

A presente pesquisa vem discorrer sobre a importância da intersetorialidade na efetivação da Política Pública de Atendimento Socioeducativo, com foco na interação entre a Socioeducação e Educação Escolar, abrangendo a realidade do Programa de Atendimento Socioeducativo desenvolvido no município de Ourilândia do Norte, Estado do Pará. Para adentrar ao assunto, realizou-se um breve histórico acerca das diferentes iniciativas políticas, que ao longo da história do Brasil tem contribuído para definir e legitimar o direito de crianças e adolescentes, com ênfase na garantia de direitos do adolescente autor de ato infracional. Para realizar a pesquisa adotou-se a abordagem qualitativa e como instrumento de coleta de dados, a entrevista estruturada. O público amostral foi composto por profissionais do serviço socioeducativo e da Educação Escolar. Com base na investigação realizada, percebeu-se que a interlocução entre socioeducação e Educação está aquém do que preconiza o SINASE, tendo como principal fator, a falta de conhecimento acerca da Política Nacional de Atendimento Socioeducativo e sua operacionalização.
Évolution cosmique des galaxies
Authors: ELBAZ David , LE FLOC’H Emeric
Published: August 2021

Quelques années à peine après la découverte de l’existence des galaxies, nous avons compris en étudiant leur dynamique que l’Univers avait une histoire, celle qui a succédé au Big Bang et à l’expansion de l’Univers. Malgré cela, il a fallu de nombreuses années pour réaliser que les galaxies évoluaient en permanence, tant au niveau de leur forme que de leurs couleurs ou de leur activité de formation d’étoiles ou de la croissance de leur trou noir galactique. Il faudra attendre le milieu des années 1990 pour que l’on réalise que la formation des galaxies était un processus véritablement continu, après l’échec cuisant de la quête des galaxies primordiales entreprise dans les années 1980-1990. L’histoire de l’évolution cosmique des galaxies suit de près les progrès réalisés dans les techniques d’observation de l’univers, avec l’arrivée des télescopes de la classe des 8-10 mètres, le télescope spatial Hubble et l’approche multi-longueurs d’ondes révélant à chaque fréquence du spectre électromagnétique une facette différente des galaxies.

A semi-automated procedure for the emitter-receiver geometry characterization of motor-controlled lidars
Authors: Di Paolantonio Marco , Dionisi Davide , Liberti Gian Luigi
Published: August 2021

Abstract. To correctly understand and interpret lidar acquired signals and to provide high quality data, the characterization of the lidar transmitter-receiver geometry is required. For example, being fundamental to correctly align lidar systems, this characterization is useful to improve the efficiency of the alignment procedure. In addition, some applications (e.g. air quality monitoring) need to quantitatively interpret the observations even in the range where the overlap between the telescope field of view and the laser beam is incomplete. This is generally accomplished by correcting for the overlap function. Within the frame of Lidar based networks (e.g. ACTRIS/EARLINET) there is a need to define standardized approaches to deal with lidar geometry issues. The multi-wavelength multi-telescope Rayleigh-Mie-Raman “9-eyes” system in Rome Tor Vergata, part of ACTRIS/EARLINET, has the capability to change through computer-controlled servomotors, the orientation of the laser beams and the 3D position of the diaphragm of the receiving optical system around the focal point of the telescopes. Taking advantage of these instrumental design characteristics an original approach to characterize the dependency of the acquired signal from the system relative transmitter-receiver geometry (the mapping procedure) was developed. The procedure consists in a set of programs controlling both the signal acquisition as well as the motor movements. The approach includes solutions to account for atmospheric and laser power variability likely to occur during the mapping sessions. The paper describes in detail the developed procedure and applications such as the optimization of the telescope/beam alignment and the estimation of the overlap function. The results of the mapping applied to a single combination of telescope-laser beam are shown and discussed. The effectiveness of the mapping-based alignment was successfully verified by comparing the whole signal profile and the outcome of the telecover test, adopted in EARLINET, for a manual and a mapping-based alignment. A significant signal increase and lowering of the full overlap height (from 1500 m to less than 1000 m) was found. The overlap function was estimated down to 200 m and compared against the one obtained from a geometric model. The developed procedure allowed also estimating the absolute and relative tilt of the laser beam. The mapping approach, even in simplified versions, can be adapted to other lidars to characterize and align systems with non-motorized receiving geometry.
Evaluation and Application of Precipitable Water Vapor Product from MERSI-II onboard the Fengyun-3D Satellite
Authors: Zhang Wengang , Wang Ling , Yu Yang , Xu Guirong , Hu Xiuqing , Fu Zhikang , Cui Chunguang
Published: August 2021

Abstract. The evaluation of precipitable water vapor (PWV) derived from the advanced Medium Resolution Spectral Imager (MERSI-II) onboard FengYun-3D is performed with the PWV from Integrated Global Radiosonde Archive (IGRA) based on 626 sites (54214 match-ups) in total during 2018–2021. The averaged PWVs from MERSI-II and IGRA both present the distribution opposite to latitude, with great PWV mostly found in the tropics. In general, a good consistency exists between the PWVs of MERSI-Ⅱ and IGRA, and their correlation coefficient is 0.9400 and root mean squared error (RMSE) is 0.31 cm. The peak values of mean bias (MB) and the mean relative bias (MRB) are 0.00 cm and −2.38 %, with the standard deviations of 0.25 cm and 16.8 %, respectively. For most sites, the PWV is underestimated with the MB between −0.28 cm and 0.05 cm. However, there is also overestimated PWV, which is mostly distributed in the surrounding areas of the Black Sea and the middle of South America. The peak values of MB are found in February and July over the Southern and Northern Hemisphere, respectively. More than 66.91 % of retrievals falling within the except error (EE) envelope during all months. Overall, the MRB and RMSE become larger with the increasing temporal and distance discrepancy, and it is contrast for EE and correlation coefficient. Besides, the distance discrepancy impacts the evaluation more. The application of PWV product over Qinghai-Tibet Plateau shows that the transport of water vapor along the Brahmaputra Grand Canyon is obvious and it is more significant in July.
Evaluating landslide response in seismic and rainfall regime: A case study from the SE Carpathians, Romania
Authors: Kumar Vipin , Cauchie Léna , Mreyen Anne-Sophie , Micu Mihai , Havenith Hans-Balder
Published: August 2021

Abstract. There have been many studies exploring the rainfall induced slope failures in the earthquake affected terrain. However, studies evaluating the potential effects of both landslide triggering factors; rainfall and earthquake have been infrequent despite the rising global landslide mortality risk. The SE Carpathians, which have been subjected to many large historical earthquakes and changing climate and thus resulting in frequent landslides, is one such region that is least explored in this context. Therefore, a massive (~9.1 Mm2) landslide, situated along the Basca Rozilei River, in the Vrancea Seismic Zone, SE Carpathians is chosen as a case study area to achieve the aforesaid objective. The present state of slope reveals the Factor of Safety in a range of 1.17–1.32 with a static condition displacement of 0.4–4 m that reaches up to 8–60 m under dynamic (earthquake) condition. The Groundwater (GW) effect further decreases the Factor of Safety and increases the displacement. Ground motion amplification enhances the possibility of slope surface deformation and displacements. The debris flow prediction, implying the excessive rainfall effect, reveals a flow having 9.0–26.0 m height and 2.1–3.0 m/sec velocity along the river channel. The predicted extent of potential debris flow is found to follow the trails possibly created by previous debris flow and/or slide events.

Authors: Adeniyi Olusola Bolarinwa , YOLOYE Tolulope Wale
Published: August 2021

This paper examines various means of funding cooperative societies owned by teachers to promote members' economic strength. This is a self-financing body with no grant or support from the government or agencies. This paper sought to identify various means used in generating funds by cooperative societies and how this has helped promote members' economic strength. One hundred and forty-five (145) members of eight (8) societies participated in the study. The instruments used in collecting data were; Fund Creation Checklist (FCC) and Members Economic Strength Questionnaire (MESQ). Data were analysed using Descriptive Statistics and Pearson Product Moment Correlation (PPMC). Result revealed an insignificant negative relationship between fund creation and members economic strength promotion with (r= -0.085, > .05). Thus, it shows that it is not certain that the fund generated by the cooperative society solely accounted for the promotion of members’ economic strength. It was concluded that cooperative societies and members should engage in viable businesses that will yield high profits, and proper fund management should be of priority for society and members.

The emergence of queer theory and politics in the 1990s was widely touted as

heralding a new era of sexual inclusivity. However, this has not proved to be the case

for everyone. This fictocritical essay features three vignettes of gay male Asian

migrants living in Australia. We suggest that the sense of belonging these men

develop is complex and difficult. All three subjects find themselves straddling two

artificially polarised worlds: the white and modern world of ‘gay Australia’ and the

racialised and striated ‘migrant’ world. This work explores some intersections of

sexuality, belonging, race and migration in contemporary Australia through

alternating acts of scholarly and creative writing.

This work is an experiment in queering the book review genre. It is a conversation or

dialogue between two queer writers, Karina Quinn and Dallas John Baker, about

Baker’s novella I Go Far Away Sometimes (2014) and the practice and process of queer

writing. This queered review touches on queer desire, the abject, sentimentality,

metaphors for writing practice and discusses a queer ethics of seeing. As such, the

review performs a kind of knowledge creation beyond what is usual for a book review

Analisis Energi Baru Terbarukan Untuk Sistem Kelistrikan Desa
Authors: Fathara Aesha
Published: August 2021

Electricity is a primary need for society. Energy that will never run out of availability is energy from solar radiation. Indonesia is an agricultural country that can utilize alternative energy by utilizing biomass energy, one of which is rice husk and straw waste. Based on data from the BMKG Paloh Station, Sambas Regency has a fairly large intensity of sunlight because it is located just below the equator. The intensity of light in the dry season can reach 6 hours in a period of 8 hours of sunlight, namely from 8.00 - 16.00. The resulting energy conversion is 38.01 mj/m2/day. Meanwhile, for the biomass potential from the BPS data of Sambas Regency in Tebas District, there are 6,730 ha of rice fields, which can produce 403 tons of rice husk and straw waste in one day for 1 year and can produce 5 million Mj/day . The results of the conversion analysis of the optimization of renewable energy for power plants that have an annual peak power of 45kW and daily energy consumption of 330kWh/day obtained the most optimal potential for rice husk and straw waste, which requires an initial capital of $ 67,120 with a total net present minimum cost. Electricity from the system cost is also minimum at US$ 0.005/kWh. And in technical economic analysis, modeling this system requires a payback period of about 11 years without grid bills and 5 years with grid bills. Meanwhile, conversion using PV requires larger capital and longer payback.

Recently, in the Republic of Kazakhstan, as well as in other countries of theAsian region, it is becoming more and more urgent to strengthen the operated reinforcedconcrete structures with external reinforcement systems with carbon materials during thereconstruction of any engineering structures. In order to eliminate the consequences of concretedestruction and reinforcement corrosion as a result of long-term exposure to natural factors andaggressive environments, carbon fiber external reinforcement systems are widely used during the operation of structures designed to repair and strengthen the load-bearing structures of artificialstructures. External reinforcement is used to increase the seismic resistance, strength andreliability of the structures being built, as well as to increase the time between repairs. The repairsystem provides for the use of materials and technologies that ensure stopping and preventingfurther corrosion of reinforcement and concrete, reliable adhesion of repair compounds with oldconcrete, increased water resistance, frost resistance and chemical resistance. This articledescribes FibARM carbon materials that are used to strengthen columns and pylons, broadbandreinforcement of slabs, beams, crossbars and structures with increased requirements forreinforcement joints, covering reinforcement of concrete with large-scale grid cracking.The mainmethods of strengthening the stretched and bent elements of building structures of artificialstructures are considered, and the technology of work on strengthening the structures of artificialstructures is also given.
DEMAND FOR MONEY AND HAYEKIAN TRIANGLES
Authors: Potuzak Pavel
Published: August 2021

Friedrich August von Hayek (1935) developed a specific business cycle theory in which interactions between the real and monetary sectors play a central role. In the first version of the theory, shocks to the money supply deflect market interest rate from the natural level and thus give false signals to entrepreneurs about relative demand between present goods and future goods. This idea was represented in a simple graphical tool, which was later called the Hayekian triangle. The structure of capital and the production process are depicted in a diagram that maps flows of resources from early stages of production to late stages, and finally to the hands of the consumer. On the basis of this theory, the prelimi- nary recommendation for the monetary authority was to freeze the money supply in order to prevent fluctuations in the structure of production (Hayek 1928).

Introduction: Caregivers help a person in those actions which cannot be performed by an individual independently; a person’s personal needs, environmental barriers that hinders an individual’s abilities etc. This ultimately puts an increased burden on the caregiver. This study was conducted to determine the levels of caregivers’ burden among the parents of children with cerebral palsy.
Material & Methods: A cross-sectional survey was conducted on 298 parents of children with cerebral palsy. Non-probability convenience sampling technique was used to collect data from the parents coming to the National Institute of Rehabilitation Medicine, Islamabad. The parents of children with cerebral palsy who were having auditory, cognitive or visual impairment were excluded from this study. Demographic information form and Caregiver Burden Inventory were used for the data collection. The data was analysed through IBM SPSS version 21 and results were presented in the form of frequency, percentages and mean ± sd with p-value wherever needed.
Results: the result of this study showed a greater need for respite and other services for caregivers of children with cerebral palsy. The overall Caregiver Burden Inventory score was 45.19 ± 11.9. Out of the total included participants, 163 (54.33%) participants sometimes needed relief, 116 (36.67%) needed frequent need for relief and other services while 19 (6.33%) of the included parents rarely needed relief and other services.
Conclusion: Majority of the caregivers of children with cerebral palsy needed relief and other services (compromise the growth, physical and emotional health and social relationship) to manage caregivers’ burden.

Published: August 2021

Introduction: Psychological issues are common in patients with spinal cord injury (SCI) which negatively affects rehabilitation outcomes. Therefore, early psychological interventions are as important as physical rehabilitation. The aim of the study was to systematically review literature regarding the effects of psychological interventions on rehabilitation outcomes in patients with SCI.
Material & Methods: A systematic review was conducted according to the PRISMA guidelines. Literature was searched in PubMed and PEDro databases. Articles published in English language from earliest record to August 2020 were searched. Observational and interventional studies which assessed effects of different psychological interventions on rehabilitation outcomes in patients with SCI were included. Review articles, editorials, short communications and conference papers were excluded. Quality assessment of the interventional studies was assessed using PEDro scale while methodological quality of the observational studies was carried out using NIH quality assessment tools.
Results: On the basis of eligibility criteria, 13 studies were included. Out of the total studies, 11 were observational studies and the remaining 2 were interventional studies. The included studies reported that psychological interventions improve rehabilitation outcomes such as functional independence, community participation and quality of life.
Conclusion: Psychological treatment is an effective complement to physical rehabilitation interventions to improve functional status of patients with SCI.
Design Principles of a Responsive Pedagogical Model for Multimodal Skills of Oral Presentation
Authors:   UCSI University, Lee Sze Seau
Published: August 2021

Within the scope of pedagogy, established methods have been found to be incongruous with the multimodal skills required of oral presentations in the 21st century. Despite pedagogical innovations situated in native-speaking and advanced countries being so productive in experimenting with pedagogical techniques for various types of oral skills, multimodal skills of oral presentations have still been overlooked. The author is a practitioner in Malaysian higher education who struggles with this pedagogical dilemma in her daily professional life. Therefore, to respond to this practical issue and theoretical gap, the author designed a pedagogical model named the Responsive Multimodal Oral Presentation Pedagogy (RMO2P) to respond appropriately and proactively to the gap in oral presentation pedagogy. A practical action research that was based on McNiff & Whitehead’s (2011) action-reflection cycle was implemented in a tertiary Malaysian classroom for 13 weeks contributed to five applicable and theoretically informed design principles of RMO2P which are based on the spirit of responsiveness. It is hoped that the explicit discussion on its design principles could inspire other teachers with no external funding and sophisticated technical expertise to embark on research for pedagogical improvement.

Development and Validation of Analytical HPLC-UV Method for simultaneous estimation of Losartan and its active Metabolite EXP-3174
Authors: Singh Alka , Upmanyu Neeraj
Published: August 2021

Background: The combination therapy of Losartan and active metabolite has proven to be beneficial as compare to either drug monotherapy. Losartan is a highly selective, orally active, non-peptide angiotensin II receptor antagonist indicated for the treatment of hypertension, which is one of the most important causes of mortality and morbidity in the modern world. It has a more potent active carboxylic acid metabolite EXP-3174 (2-butyl-5-chloro-3-[[4-[2-(2H-tetrazol yl)phenyl]phenyl]methyl]imidazole-4-carboxylic acid). Losartan and its active carboxylic acid metabolite EXP-3174 block the vasoconstrictor and aldosterone-secreting effects of angiotensin II by type ATI receptor blockage. Following oral administration, losartan is rapidly absorbed, reaching maximum concentrations 1–2 h post-dose. Result: The selected analytes were effectively separated on thermo β-basic C18 (100×4.6 mm, 5 µm) column using mobile phase consisting of 20mM monobasic potassium phosphate and 0.2% TEA with acetonitrile and iso-propyl alcohol in gradient mode. The eluent was monitored at 228nm at 1.0 ml min-1 flow rate. The total run time was less than 12 min. Conclusion: The active carboxylic acid metabolite E-3174 is about ten times more potent than losartan. In healthy volunteers, the concentrations of the active carboxylic acid metabolite EXP-3174 were found to be more closely parallel angiotensin II antagonism than those of the parent compound. Thus, the angiotensin II blocking activity of losartan is predominantly based on its major active carboxylic acid metabolite EXP-3174. Given this as background and to our best knowledge, there is no HPLC-UV method available or published simultaneous estimation of losartan with its active metabolite.

Authors: Kha Tuyen C.
Published: August 2021

The objective of this study was to investigate the efficiency of phenolic extraction and antioxidant activity from sesame cake using water extraction method and to evaluate the possibility of employing microwave irradiation to improve the extraction yield. The result showed that extraction temperature had major influence on total phenolic content and antioxidant activities of the extracts, whereas extraction time was found to be insignificant. The optimum extraction condition recommended were 90oC for 30 min in this research. Furthermore, microwave pre-treatment at 120 s could have significantly positive influence on the overall extraction yield, especially the total phenolics and antioxidants based on FRAP assay. Therefore, the obtained results suggest that sesame aqueous extracts could be a source of antioxidants with more feasible applications in food as well as other industries.
Field assessment of the efficacy of M.B., LIBDV and Winterfield 2512 strain vaccines against infectious bursal disease in chickens
Authors: Quach Anh T.
Published: August 2021

Live virus vaccines are very important parts of the prevention of Infectious Bursal Disease (IBD) in chickens. However, the successful IBD vaccination depends on IBD field pressure, vaccination technique, the immune status of the chicken, and especially IBDV strains used in the vaccines which are able to break through a higher level of maternal-derived antibodies (MDA). The objective of this field study was to compare the efficacy of a new vaccine based on M.B. strain to other commercial vaccines (LIBDV and winterfiled 2512) in terms of speed of antibody immune response and interference to Newcastle Disease (ND) vaccination. Six houses of broilers, each with 15,000 to 16,000 chickens, were divided into two groups: (1) vaccinated with M.B. strain (group A) and (2) vaccinated with LIBDV or 2512 strains (group B). Blood samples were collected prior to the 1st IBD vaccination, and at 21, 28 and 35 days of age for IBD and ND antibodies. Comparison of lesion scores and uniformity of the bursa of Fabricius (BF) at 28 and 35 days of age was carried out. Results showed that both groups had good immune responses, but group A showed significantly higher IBD antibody titers at 28 and 35 days of age. Antibody titers for ND and histopathological lesion scores of the BF were not significantly different between the 2 groups. The BF in group A was more uniform and had fewer lesions when compared with that in group B. In conclusion, the IBD vaccine with an M.B. strain can provide better immunological efficacy than LIBDV and 2512 strains.
