Authors: Patel Krishna Kumar , Yadav A.K. , Patel Y.K.
Published: August 2022

Agriculture is the prime importance to human beings. Without agricultural produce, no one can imagine surviving. The influence of monsoon and market on the farm, farmer and farming sector is increasing day by day due to global warming and political interference to some extent. Considering these facts the present review report is focused on the study of the impacts of various aspects of media, market and monsoon on agriculture. This study reports that the media in spite of being the fourth pillar of democracy is not able to play its role properly either intentionally or unintentionally. Media is not giving much importance to covering the farmer’s demands, difficulties, the monsoon forecast and the interference of the middleman/ or Dalal (i.e. intermediaries) in the market. Consequently, the condition of farmers has reached a critical situation and the cases of farmer’s suicide have been increased abruptly in the current decade. This article is, thus, tried to report the farmer’s pain and punctuations in their life and also reported how media and the market, like a monsoon, are exacerbating their wound in place healing. This article also discusses how media can take part in agricultural development to some extent.

Published: August 2022

El mercado ofrece turbinas eólicas de pequeña escala como una solución parcial para reducir la factura eléctrica en viviendas. Sin embargo, en algunos casos el rendimiento ofrecido supera el obtenido, esto se debe a las bajas velocidades del viento en las zonas residenciales y al efecto de la turbulencia sobre los aerogeneradores. El objetivo de este trabajo es determinar la influencia local de los obstáculos en la turbulencia y describir el desarrollo de la turbulencia en función de la altura, comparando dos torres meteorológicas: una colocada entre árboles y otra colocada en una zona sin obstáculos cercanos. Se pretende determinar si dentro de un paisaje específico pueden encontrarse lugares con menor turbulencia debido a una reducción de los obstáculos de manera local. Las mediciones obtenidas entre octubre de 2018 y septiembre de 2019 se procesan y mediante histogramas se compara la intensidad de turbulencia en función de la altura. Se encuentra que la turbulencia es menor conforme aumenta la altura en la torre que está inmersa entre árboles; con valores de 30% a 14 metros de altura y de 50% a 6 m de altura. En el caso de la torre que está sin obstáculos, en su entorno cercano, la turbulencia es menos dependiente de la altura, con valores de 30% a 12 metros de altura y de 40% a 4 m de altura. Se reporta un valor de intensidad de turbulencia cercano al 30% como el más frecuente entre los datos obtenidos por los diez anemómetros del estudio.

L’étude avait pour but de documenter les connaissances des populations locales sur l’intérêt socioéconomique et médicinales de Haematostaphis barteri dans les localités de Bidzar, Figuil, Boula-ibbi and Lagam, au Nord-Cameroun. Elle s’est déroulée entre septembre et novembre 2018 et a impliqué 93 personnes de trois groupes ethniques (Guidar, Peulh et Guiziga) et choisies de façon aléatoire. Constitués d’hommes, de femmes, de jeunes, des personnes âgées et des tradithérapeutes. La collecte des données a été faite par des entrevues semi-structurées. Ces entretiens ont été conduits en langues française et locale, avec recours parfois à un interprète. Des paramètres ethnobotaniques comme la valeur d’usage et consensuelle, le taux de réponse, l’indice culturel d’importance, le niveau de fidélité et le degré de consensus sur la médication ont été utilisés pour évaluer l’importance de H. barteri dans les localités étudiées. Les résultats obtenus révèlent sur le plan ethnique et genre, une forte participation des Guidars et une dominance du genre masculin. Ces enquêtés pour la plupart étaient analphabètes et exerçaient comme activité principale l’agriculture (68,82%) soutenue par un système d’entraide appelé « Sourgha ». Le nom local de H. barteri variait d’une ethnie à l’autre et était, soit une combinaison de la saveur des fruits et de sa disposition sur l’arbre, ou alors un assemblage couleur et nombre de fruits par grappe. Cette espèce est employée dans quatre (04) domaines d’utilisations, avec un large consentement pour les usages alimentaires (4 UV) et médicinaux (3UV). Le faible consentement (1,33UV) est enregistré pour son utilisation sous forme de bois d’énergie. Les fruits sont majoritairement utilisés dans l’alimentation (37%) et sa vente procure aux ménages des moyens de subsistance ; alors dans la catégorie médicinale, ce sont les feuilles, les écorces et les racines sous forme de décoction qui sont sollicitées pour traiter dix (10) affections ; dont l’anémie, la fièvre, le mal de ventre, la typhoïde, le mal d’estomac et le paludisme comme maladies les plus traitées. Pour booster l’effet du phytomédicament, H. barteri est parfois associée à Tamarindus indica, Acacia nilotica et au miel. Aucune mesure de gestion durable et rationnelle de l’espèce n’a été déclarée par nos enquêtés, toutefois, ils disent avoir mis en place des stratégies comme la multiplication des champs et la diversification de cultures et l’abandon des terres pauvres au profit de nouvelles terres fertiles, pour faire face aux impacts négatifs des changements globaux. Les multiples utilisations et très variées, associées à l’absence de mesures adéquates de gestion soutenable et aux effets du changement climatique affectent les individus de cette espèce dans les localités investiguées ; ainsi des mesures de préservations s’imposent.

Ballada o adaptacji — gdzie kryje się sens kolejnej pieśni o Narayamie?
Authors: Poborca Tomasz
Published: August 2022

The main purpose of this article is to analyze the text of Shichiro Fukazawa’s The Ballad of Narayama, its two Japanese film adaptations by Keisuke Kinoshita and Shohei Imamura, and to explain the idea behind another attempt by cinema and cinema audiences to assimilate the story into the changing film discourse. Referring both to classical and postmodern theories of adaptation of literature represented in the works of Alicja Helman and Marek Hendrykowski, and to current film studies strategies, the author deconstructs the movies, describes the differences in adaptation processes, and looks for their causes, using historical and anthropological contexts. The results of the analysis are contrasted with the reception of the films by Polish critics who attempted to interpret Imamura’s film by emphasizing its animal motifs and often juxtaposed it with the highly theatrical manner of the earlier work by Kinoshita.
Mesenteric Schwannoma, Intestinal Malrotation and Ileal Diverticulum: A Unique Association
Authors: Abreu da Silva Alberto , Ferreira Andreia , Cusati Pierpaolo , Martins José Augusto
Published: August 2022

Mesenteric schwannomas are rare benign tumors that arise in the mesentery. Ileal diverticula and intestinal malrotation in adults are rare findings, since they are usually asymptomatic. We present the case of an 86-year-old man, without any known previously known medical conditions, who was admitted in the emergency department with recurrent abdominal distension and intense pain. The radiological study suggested an intestinal malrotation. An exploratory laparotomy confirmed the intestinal malrotation with intermesenteric bands, as well as a mesenteric mass adjacent to an ileal diverticulum. Following a segmental enterectomy, the histology of the mass reported a mesenteric schwannoma. To the best of our knowledge, this is the first report of such association. We therefore present this report to showcase the diagnostic and therapeutical challenges in managing these conditions.

Published: August 2022

Parents are responsible for their children’s health care, and their oral health-related knowledge, attitude, and habits can affect their children’s oral health. Aim: The objective of this study was to evaluate parents’ knowledge, attitudes, and practices regarding their children’s oral health. Methods: In this study, a sample of 398 parents of 4- to 6-year-old children completed a self-designed questionnaire. The parents’ oral health-related knowledge, attitudes, and practices were assessed. Children’s oral health was evaluated using decayed, missing, and filled tooth index (dmft). Data were analyzed using the SPSS version 23.0 with a p < 0.05 as statistically significant. Categorical data were reported as frequency (%), and continuous data were reported as mean ± SD. Moreover, Spearman’s correlation, multiple regression, Mann-Whitney test, Kruskal Wallis test, and Kolmogorov-Smirnov test were used. Results: Most of the parents had a satisfactory level of knowledge and positive attitudes regarding their children’s oral health. The knowledge and attitude scores were higher among parents with higher education (p<0.001), and the knowledge score was higher among mothers (p=0.004). Also, the attitude score was correlated with the number of decayed, missed, and filled teeth of children (p=0.01, p=0.04, and p=0.007, respectively). However, there was no significant relationship between dmft and the parents’ knowledge, attitudes, and practices using multiple regression. The mean dmft of children was 6.86 ± 3.56, and most of the parents had poor oral health-related practices. Conclusion: The parents’ level of knowledge and attitudes were satisfactory, but they had poor oral health practices. Moreover, there was no significant relationship between children’s oral health and their parents’ level of knowledge, attitudes, and practices. Educating programs and strategies are needed to enhance parents’ oral health-related attitudes and knowledge and, more importantly, change their oral health practices.

Com o avanço das tecnologias da informação e o surgimento da pandemia de Covid-19, os movimentos negacionistas vêm ganhando força. Buscamos neste artigo, no formato de ensaio teórico que discute dois fatos históricos – a produção de vacinas e a forma da Terra – integrar conhecimentos históricos que possibilitem reflexões mais profundas por parte de professores de ciências. Discutimos alguns componentes psicológicos do comportamento humano. Ao abordarmos a história das vacinas e a história da Astronomia, elas se parecem, num primeiro momento, histórias distintas e com momentos históricos diferentes. Contudo, quando nos aprofundamos nas discussões, percebemos que ambas compartilham de muitos aspectos em comum, dentre eles, as notícias falsas, que assolam a sociedade e as teorias negacionistas: antivacinas e terraplanistas. Consideramos a história da ciência essencial na educação em ciências para o combate ao negacionismo científico e ao obscurantismo.
Algorithm Development for Quality Control of RangeFinder Wave Time Series Data at Ocean Research Station

Published: August 2022

Ocean Research Station is a comprehensive ocean research infrastructure built to collect and provide real-time data with state-of-the-art observation systems. This station operates various research facilities, and the data is actively used for research in each field. In particular, since wave data is produced through the remote-sensing observation method, they are valuable as observation data. Unlike the direct observation method, they can stably collect data and store long-term observation data on severe weather. However, there is a limitation that outlier may occur due to the process of measuring and collecting data or the effects of temporary environmental changes. This study improves the remote wave data quality of MIROS RangeFinder installed at the Socheongcho Ocean Research Station using an algorithm and confirms the reliability by comparing it with the wave buoy observation data operated by the Korea Meteorological Administration. The algorithm used is a Spike removal median filter, which is applied after adjusting the conditions and variables according to the characteristics of the Socheongcho wave data. Also, we developed a new filter using a variable threshold to increase the outlier detection rate. As a result, the final algorithm shows a high outlier detection rate, but some outliers are still not removed, so improvements are required to enhance the algorithm’s performance. In addition, continuous research on the remote-sensing wave observation method is required to compensate for the limitation that the accuracy is slightly lower than that of the direct observation method.

Published: August 2022

In this study, a forecast system for the occurrence of cold waters in the eastern coast of Korea was developed by combining the ROMS ocean model and the WRF regional atmospheric model. The 1-day hindcast and 3.5-day forecasts from April 1 to August 31, 2021, successfully reproduced and forecasted the temporal and spatial changes of coastal cold waters. Three case studies with different surface boundary conditions in the ROMS model confirmed that the wind is a primary driver for the occurrence of cold waters in the region. The performance of the ROMS was improved by high-resolution WRF outputs, and through error correction using the water temperature data from the real-time stations, the average RMSE of 9 stations for Forecast Day-3 was 0.73℃, indicating a prossibility of high-precision forecast.

Published: August 2022

It is known that the prognosis of patients affected by light-chain (AL) or transthyretin-related (TTR) amyloidosis is poor. TTR amyloidosis has usually shown a slower progression than AL amyloidosis, both hereditary TTR amyloidosis, where there is an inherited mutation in the DNA, and wild-type TTR amyloidosis, which usually affects the elderly. In this paper, the current literature about heart transplantation on cardiac amyloidosis patients is extensively reviewed. The two most frequent types of cardiac amyloidosis have been considered for heart transplantation: AL amyloidosis and wild-type TTR amyloidosis. According to this analysis, it is reasonable that heart transplantation may represent a valuable option in carefully selected patients. Moreover, it could improve prognosis, enabling autologous stem cell transplantation in the AL amyloidosis subgroup. In our humble opinion, it is mandatory to define a multidisciplinary approach to help select candidates to obtain the most effective results.

Published: August 2022

The development of age-related cardiovascular (CV) dysfunction increases the risk of CV disease as well as other chronic age-associated disorders, including chronic kidney disease, and Alzheimer’s disease and related dementias. Major manifestations of age-associated CV dysfunction that increase disease risk are vascular dysfunction, primarily vascular endothelial dysfunction and arterial stiffening, and elevated systolic blood pressure. Declines in nitric oxide bioavailability secondary to increased oxidative stress and inflammation are established mechanisms of CV dysfunction with aging. Moreover, fundamental mechanisms of aging, termed the “hallmarks of aging” extend to the CV system and, as such, may be considered “hallmarks of CV aging”. These mechanisms represent viable therapeutic targets for treating CV dysfunction with aging. Healthy lifestyle behaviors, such as regular aerobic exercise and certain dietary patterns, are considered “first-line” strategies to prevent and/or treat age-associated CV dysfunction. Despite the well-established benefits of these strategies, many older adults do not meet the recommended guidelines for exercise or consume a healthy diet. Therefore, it is important to establish alternative and/or complementary evidence-based approaches to prevent or reverse age-related CV dysfunction. Targeting fundamental mechanisms of CV aging with interventions such as time-efficient exercise training, food-derived molecules, termed nutraceuticals, or select synthetic pharmacological agents represents a promising approach. In the present review, we will highlight emerging topics in the field of healthy CV aging with a specific focus on how exercise, nutrition/dietary patterns, nutraceuticals and select synthetic pharmacological compounds may promote healthy CV aging, in part, by targeting the hallmarks of CV aging.

A Study on the Development of Art Derivatives in Chinese Museums —Take the Beijing Palace Museum as an Example
Authors: Xiang Yuhang
Published: August 2022

With their history and culture, museums have become one of the most important choices for the cultural and artistic consumption of the public. The exploitation of art derivatives makes it possible to increase the visibility of museums. While promoting traditional Chinese culture and allowing the audience to experience the artistic atmosphere, art derivatives can also bring museums closer to the social public, better reflect and perform the social functions of museums. Only a very small number of museums in China are currently developing art derivatives, and most have no advantage of research and development. Among them, the Palace Museum in Beijing plays a good role as a model in the development, production and sales of art derivatives relative to other museums. In the course of this article, through the analysis of the research and development experiences of the art derivatives of The Palace Museum in Beijing, it summarizes and describes research and development models that are noteworthy for reference and study. It is hoped that this will inspire further museums in China to develop art derivatives.

The purpose of this research is to find out and analyze the public's understanding of Agricultural Zakat and also the management in agricultural zakat in the Samata village, Tangaran, Sambas. The research type used in this research is field research. Data collection methods were done through observation, interviews and documentation, and relevant supporting literatures on the discussing issue. The data was further analyzed using a descriptive analysis method. The results showed that the community in that village had a general understanding of agricultural zakat. This could be seen from several indicators such as: how much the agricultural zakat nisab is, when they have to pay agricultural zakat, the amount that they have to pay and where they have to pay it, so that the village community whose harvests have reached the nisab always pay the zakat. The management in agricultural zakat in the village has two aspects, which are zakat’s collection and distribution. In terms of the management of agricultural zakat in Semata village, it can be said to be good. However, the non-centralization of the amil zakat institutions makes management overlap, because the zakat proceeds are not evenly distributed among the existing mosques.
Keywords: Public understanding, zakat management, agricultural zakat

Geological Characteristics and Controlling Factors of Deep Shale Gas Enrichment of the Wufeng-Longmaxi Formation in the Southern Sichuan Basin, China
Authors: Li Jing , Li Hu , Yang Cheng , Wu Yijia , Gao Zhi , Jiang Songlian
Published: August 2022

To identify the factors controlling high-quality deep shale gas reservoirs and the exploration and development potential of the Lower Paleozoic marine shale in the Sichuan Basin, the sedimentary environment of deep shale was comprehensively analysed using core thin sections, scanning electron microscopy, gamma ray spectrometry logging, and elemental logging data. In addition, the geological conditions of deep shale gas accumulation and the effect of tectonic processes on the preservation conditions are discussed based on the experimental data of mineral composition analysis, geochemical features, and reservoir spatial characteristics. (1) The sedimentary environment changes from an anoxic water environment to an oxygen-rich oxidizing environment from bottom to top in the Wufeng-Longmaxi Formation in southern Sichuan. The deep shale gas reservoir shows overpressure and rich gas characteristics, namely, high formation pressure (2.0~2.2), high porosity (20%~55%), and high gas content (4.0~5.0 m3/t). (2) The favourable sedimentary environment has a higher hydrocarbon generation potential and deposits of rich organic matter and siliceous particles. During the hydrocarbon generation process, the rich organic matter generates a large number of organic pores and a large specific surface area, which provides the main reservoir and adsorption space for free and adsorbed shale gas. A large number of biogenic siliceous particles provide a solid rock support framework for the shale reservoir, thereby maintaining excellent reservoir physical properties. (3) Late and small stratigraphic uplifts result in a short shale gas escape time and favourable preservation conditions. Additionally, the small-scale faults and a high-angle intersection between the fracture strike and the geostress direction are conducive to the preservation of shale gas. (4) A high formation pressure coefficient, a sedimentary environment rich in organic siliceous deep-water continental shelf microfacies, and a relatively stable tectonic structure are conducive to the accumulation of deep shale gas.

Penelitian ini bertujuan untuk mengetahui komponen pembelajaran imla’ di pondok pesantren modern dan pondok pesantren salaf di Ponorogo, dan untuk mengetahui bagaimana proses pembelajaran imla’ antara pondok pesantren modern dan pondok pesantren salaf di Ponorogo. Penelitian ini merupakan penelitian kualitatif dengan menggunakan model studi analisis lapangan. Metode pengumpulan data yang digunakan oleh peneliti adalah metode observasi, wawancara, dan dokumentasi. Sedangkan teknik analisis data yang digunakan adalah teknik analisis data milik Miles dan Huberman yang terdiri dari reduksi data, display data, dan kesimpulan. Hasil dari penelitian ini menunjukkan bahwa komponen pembelajaran imla’ di pondok pesantren modern dibangun atas dasar pembelajaran imla’ yang digunakan sebagai dasar pembelajaran bahasa arab, yang mana bahasa tersebut digunakan sebagai alat komunikasi. Berbeda dengan pondok pesantren salaf, yang mana komponen pembelajaran imla’ dibangun atas dasar pembelajaran imla’ digunakan untuk menghubungkan huruf dengan kaidah pegon sebagai alat bantu memahami naskah-naskah. Proses pembelajaran imla’ di Pondok Pesantren Modern Darut Taqwa lebih terpusat kepada siswa, dan mengembangkan aspek psikomotor yang mana siswa diarahkan untuk menggunakan indra pendengar (telinga), indra penglihat (mata), indra pengucap (mulut), dan jari-jarinya dengan semaksimal mungkin. Sedangkan proses pembelajaran imla’ di Pondok salaf Darul Huda lebih terpusat kepada guru dan mengembangkan pada ranah aspek afektif yang mana siswi diharapkan mampu menulis dan melafalkan huruf-huruf arab dengan benar, kemudian memahami gramatika bahasa.

Kompetensi pedagogik dan kompetensi profesional adalah bagian dari kompetensi yang harus dimiliki oleh guru sebagai unsur dalam pengelolaan pengajaran dan penentu keberhasilan pengajaran pada lembaga pendidikan. Maka sangatlah penting untuk membicarakan tentang bagaimana peran kompetensi pedagogik dan kompetensi profesional yang dimiliki oleh guru bahasa Arab. Peneliti mengkhususkan penelitiannya pada kompetensi pedagogik dan kompetensi profesional guru bahasa Arab di Madrasah Aliyah Darul Huda Ponorogo. Dan bertujuan untuk mengetahui dan menganalisis aspek-aspek yang terkait dengan kompetensi pedagogik dan kompetensi profesional guru bahasa Arab. Penelitian ini merupakan penelitian kualitatif dengan menggunakan studi analisis data milik miles dan huberman yang terdiri dari reduksi data, display data, dan kesimpulan. Hasil penelitian ini menunjukkan bahwa kompetensi pedagogik guru secara keseluruhan mempunyai kompetensi guru, dapat dilihat bahwa guru mampu mengelola pembelajaran, memahami peserta didik, merancang pembelajaran, melaksanakan pembelajaran, memanfaatkan teknologi pembelajaran, mengevaluasi hasil belajar, dan mengembangkan peserta didik. Namun ditemukan ketidakmaksimalan pada guru bahasa arab yang berhubungan dengan rancangan pembelajaran yang mana seringkali tidak sesuai dengan kebutuhan siswa, keadaan kelas dan prasarana lainnya, penggunaan metode, penyusunan RPP, dan mengembangkan kemampuan siswa. Dan kompetensi profesional guru dapat dilihat bahwa guru mampu menguasai materi, menerapkan metode pembelajaran yang bervariasi, dan menghubungkan antara konsep materi dengan dengan kehidupan sehari-hari. Dalam hal ini ditemukan guru yang kompetensi profesionalnya belum maksimal. Dalam penggunaan metode pembelajaran yang mana penggunaan metode ini harus disesuaikan dengan kondisi peserta didik dan keadaan.

Type Curves of a Vertical Well Completed Within a Pair of Inclined Sealing Faults

Type curves come in handy when our pressure buildup and pressure drawdown analysis do not yield a straight line hence generating a master curve for wells completed within a pair of sealing faults. The type curves from an observed data is superimposed on the master curve to estimate reservoir system properties. A sealing fault creates image wells, which communicate with each other and the object well. As a result, object well performance can be affected by reservoir boundaries, and positioning of a well therefore must be strategic to ensure oil production for a long time. This is because pressure drop across the producing well is the addition of the pressure drop of the object well and the several image wells created because of the inclination. This is the principle of superposition. The inclination of a sealing fault influences the number of image wells, n, with the model n = (360/θ) -1. With different angles of inclination of the sealing faults, polygons are constructed to determine the distances between the object well and corresponding image wells.

In this paper, both dimensionless pressure and dimensionless pressure derivatives type curves as functions of number of image wells, are produced assuming that a vertical well is completed within a pair sealing faults. Wellbore storage and skin effects are considered. The results provide distances for several angles of inclination. Object well design, image well distances and faults angle affect dimensionless pressure and dimensionless pressure derivative. Dimensionless pressure and dimensionless pressure derivative of 2.3026(n+1) per cycle and 0.5(n+1), respectively are observed.

Generating dimensionless pressure derivative curves helps the engineer to identify the point where the hump expires and where the straight-line analysis begins. That is the right point for well test analysis.
Optimal Well Designs and Process Frameworks: Keys to Reducing Well Cost and Winning in any Environment

Growing concerns for global energy transition and dwindling demand for crude oil has impacted the revenues and investment portfolios of most oil and gas companies. More than ever, hydrocarbon exploration and production costs require extra scrutiny and prudence. Drilling and Completions costs take a significant proportion of the capital expenditure and savings realized from this would improve development cost per barrel, improve project economics and yield better returns for all stakeholders.

To unlock the fiscal values required to win in this economic climate and attract investments to develop oil and gas assets, a paradigm shift is needed on well delivery, well design and execution processes. Cost savings opportunities exist all through the well maturation, but the highest value can be realized in the design stage. This stage involves opportunity identification, alternatives generation, setting of value based well objectives, design, and engineering etc.

This paper discusses cost saving initiatives such as advanced casing design to optimize the number of casing strings run, slim well designs, streamlined formation evaluation plan, bottom hole assembly (BHA) optimization, equipment standardization, adoption of agile methodologies to determine minimum function objectives, utilization of data-analytics tools to drive performance, application of state-of-the-art technology, extensive use of peer assists and peer reviews etc. Proper adoption of these initiatives can yield up to 30% reduction in well cost and ultimately enable oil and gas companies to compete and win in any environment.
