Botanical formulations for the ecological management of Myzus persicae (Sulzer) and Aphis gossypii (Clover) (Hemiptera: Aphididae) and their side effects on parasitoids
Authors: Castresana Jorge Eduardo , Puhl Laura Elena
Published: August 2021

The peach aphid Myzus persicae (Sulzer) and cotton aphid Aphis gossypii (Clover) (Hemiptera: Aphididae) are considered to be key pests affecting greenhouse pepper crops in Argentina as a result of their frequent occurrence and the seriousness of the damage caused by their feeding behavior and the transmission of virus. The goal of this research was to determine the efficiency of botanical products to control aphids and their side effects on parasitoids in this crop. Thus, three biorational pest control formulations derived from essential oils (EO) and plant extracts (Es) were tested, namely (i) neem EO, cinnamon EO, clove EO, oregano EO and American marigold EO (formulation 1); (ii) garlic EO and cinnamon EO (formulation 2); (iii) garlic E and rue E (formulation 3); and a soy lecithin adjuvant (lecithin), and finally, a control (water spray method). For this research, a completely randomized design was replicated 3 times. These treatments were applied directly to the foliage by means of a backpack sprayer on a weekly basis until the end of this trial. Subsequently, the total number of healthy aphids and parasitized aphids (mummies) on every leaf was recorded in the field and the laboratory through repeated measures Analysis of Variance (ANOVA) and LSD Fisher method. The results showed that formulation 1 and formulation 3 recorded a lower number of aphids and mummies compared to the other treatments. This evidence would demonstrate that these formulations repel aphids and parasitoids without the lethal effects caused by the use of broad spectrum insecticides.

Based on the hypothesis that there is a high agreement between pedologists and a smartphone application in the assessment of soil color; the objective was to compare the perceptions of pedologists and an application in obtaining the color of an Argissolo [Lixisol] (A, E and B horizons).  Ten aggregates of each horizon were collected. In a single day, under the same lighting conditions, three pedologists described the color components (hue, value, and chroma) of each aggregate (dry and moist soil) using the Munsell soil color chart. Each one of the ten aggregates, from each horizon, was photographed (dry and moist soil sequence) using the camera of a Motorola Moto G4 Plus smartphone. The distance of the camera to the aggregates was 25 ± 5 cm. Also, each aggregate was placed on a white sheet of A4 size paper (background). The application used was Soil Analysis Pro. The percentage of agreement between pedologists and application was obtained concerning hue, value, and chroma. The data were subjected to analysis of variance, in a completely randomized design, with ten replicates. Action Stat® software was used for statistical analysis. It was concluded that the agreement between pedologists and the smartphone application was medium for hue and chroma and low for value. For the dry soil condition, there is a high agreement between pedologists and the smartphone application, especially in the perception of hue and chroma. Thus, the smartphone application has the potential to be used in routine descriptions of soil color.
Protest in Russia 2017-2021: Technologies and Patterns
Authors: Shults Eduard E.
Published: August 2021

The article analyzes the patterns and technologies of organizing political protest in Russia in the period 2017-2021. The author concludes that the start of the protests in March 2017 was aimed at influencing the presidential elections in March 2018, in addition, the protests of schoolchildren were to launch the pattern of chain reaction in rising of protest actions. The author states that in this new wave of protests, there is a change of face of protest: that is an attempt to remove one of the main problems of Russian political protest - a large number of opinion leaders, each of whom has an extremely low rating, and the absence of single ideological orientation of the protest. Protest organization technologies share patterns with the radical mass forms of social protest known as the color revolutions and events of the Arab Spring. Political protests of 2017-2021 again showed the operability of simple slogans, but the impossibility of a long-term alliance in the ranks of protesters. The lack of a strong ideology makes these protests swift: explosive and rapidly fading, unable to mobilize new supporters.
Web Service Adaptation for the Customization of Early Alerts in Agriculture
Authors: Valencia Aguilar Oscar Ricardo , Lasso Sambony Emmanuel Gerardo , Corrales Muñoz Juan Carlos
Published: August 2021

Early warning systems are designed to inform the largest number of users, such as a country or a region, about a risky situation. However, in specific domains such as agriculture, it is commonly required for these alerts to be more specific according to the crops location and their properties. Consequently, the web services of these systems must be adapted. On the other hand, the enterprise services bus, with its mediation capabilities (such as message transformation and routing), and complex event processing with their monitoring characteristics, can be integrated to meet the adaptation requirements of web services at runtime. This paper presents an improvement for an early warning system for coffee production that, according to the area in which a crop is located and its phenology, manages the adaptation of alerts for coffee rust, based on the integration of an enterprise services bus and a complex events processing.
Enhancing student retention
Authors: Barroso Tanoira Francisco Gerardo
Published: August 2021

In a study I conducted in local private higher education institutions, it was observed that the most important reasons for student retention are outstanding personalized attention by tutors, school authorities, staff and professors, followed by the economic factor and academic achievement.  So, quality in attention is the first step for creating a positive learning environment for students to engage in their own learning, making schools become places where talent and opportunities meet.  Then, more than thinking in retaining students through financial strategies, marketing efforts or trying to amaze them with impressive buildings and facilities, there must be better academic tutoring and vocational orientation, less students per tutor and more effectiveness for solving their problems, also eliminating useless remedial courses.  Close and frequent relation with school authorities is very important for enhancing confidence.

What Do Beautiful Stories of Wartime Consolation Tell Us? ：A Study on The Imperial Japanese Army Consolation Group of Nihon Shimbun Remmei and Konan Ni Jun No Tabi
Authors: GUO Lixin
Published: August 2021

This paper focuses on the activities of the Imperial Japanese Army consolation group (sent to boost the morale of soldiers) on the Jiangnan front line and its commemorative book, Konan Ni Jun No Tabi. It was published in May 1939 during the Second Sino-Japanese War by the Japanese newspaper league (Nihon Shimbun Remmei) and was not available for sale to the public. The Imperial Japanese Army’s consolation mission to the war zone was highly active. Under the guise of comforting the Imperial Japanese Army and visiting battle sites, this group, while receiving preferential treatment from the military, continued to travel around war-torn Jiangnan. They eulogized the scenery of the battlefield in front of them and worked to connect the front line with the home front. In addition to being a beautiful story of the battlefield, the book Konan Ni Jun No Tabi glorified the work of this group as overwhelmingly successful and unprecedented, in this way making the text more of a beautiful story than a simple summing up of its work.In this paper, based on an analysis of this book, the purpose of these stories, hidden behind the larger narrative of the Jiangnan battlefield, is examined. Another “Jiangnan” as seen by the group is revealed, as is the reality of their work and their success.

Published: August 2021

La tortilla de maíz es uno de los principales componentes en la dieta del mexicano. En el proceso de elaboración, se emplean diferentes conservadores químicos, como el propionato de sodio y algunos acidificantes para incrementar la vida de anaquel de la tortilla de maíz. En México, al no haber una regulación bien definida sobre la adición de conservadores químicos, no existe protección hacia el consumidor. De aquí que esta investigación propone la adición de aceite esencial de tomillo como bioconservador. La metodología utilizada consistió en dos experimentos por separado: uno utilizando una concentración de 0.09 % de aceite esencial de tomillo y otro utilizando propionato de sodio a 0.2 %. Así, usando el modelo de Arrhenius, se calculó la vida útil de la tortilla de maíz adicionada con aceite esencial de tomillo a 21 °C y se encontró que fue de 104.3356 horas, mientras que para la tortilla adicionada con propionato de sodio, bajo las mismas condiciones, se obtuvo una vida de 75.3300 horas. Asimismo, mediante el factor de aceleración, se obtuvo un mejor desempeño del aceite esencial de tomillo como conservador orgánico, en contraste con el propionato de sodio. En suma, no solo mejora la inocuidad alimentaria del producto en cuanto a su vida de anaquel, sino que el aceite esencial de tomillo puede reemplazar a un conservador cancerígeno en la preparación de tortillas de maíz.

Guillain-Barré syndrome following COVID-19 infection in an elderly patient: a case report
Authors: Luvsannyam Enkhmaa , Jayaraman Arathi , Jain Molly Sanjay , Sharma Karan , Somagutta Manoj Reddy , Yallapragada Rathna Kumar
Published: August 2021

Background:

Coronaviruses can affect multiple body systems and respiratory failure is the most common complication. Since the outbreak of coronavirus disease-2019 (COVID-19) in January 2020, the association between COVID-19 and Guillain-Barre syndrome (GBS) has been growing. GBS is known to be triggered by an antecedent infection, mostly viruses.

Case Presentation:

We present a case of GBS in an 83-year-old female patient with a confirmed COVID-19 infection. The patient initially presented with fever, cough, and fatigue. She was treated with intravenous fluid and symptomatic treatment and discharged home after stabilization. Several weeks after her initial encounter, she experienced bilateral paresthesias as well as numbness and tingling in her lower extremities. The patient’s neurological symptoms were not alleviated with standard intravenous immune globulin (IVIG) therapy; however, her symptoms significantly improved with subsequent plasmapheresis therapy.

Conclusion:

Based on the emerging evidence of recent studies, there is a possible connection between COVID-19 and GBS. Clinicians should be aware of the neurological manifestations of COVID-19 infection. Early diagnosis and proper treatment of COVID-19 and its neurological symptoms are crucial to increase the chance of a successful recovery.
Modelo de negocio de economía circular: Caso tienda solidaria COANIQUEM
Authors: Mansilla-Obando Katherine , Jeldes-Delgado Fabiola , Guiñez-Cabrera Nataly , Ortiz-Henríquez Rodrigo
Published: August 2021

Existe una gran preocupación por los desechos y la cooperación para avanzar hacia el desarrollo sostenible. Frente a este desafío, las organizaciones están implementando prácticas que controlan el consumo, reducen desechos y disminuyen el impacto negativo al medio ambiente, mediante estrategias que fomentan la Economía Circular (EC). Sin embargo, la literatura sobre la comprensión actual de las estrategias circulares en organizaciones no gubernamentales, como en las tiendas solidarias, es limitada. Por ello, el propósito de este estudio es comprender el comportamiento social de los stakeholders (administrador, asistentes de venta, compradores y donadores) a colaborar en una tienda solidaria que emplea estrategias de EC. Para abordar esto, se utilizó la Teoría de Comportamiento Planeado (TPB) y la teoría de stakeholders. Además, se consideró la metodología cualitativa de estudio de caso exploratorio que incorporó entrevistas semiestructuradas a doce stakeholders que participan en la tienda solidaria COANIQUEM chilena. Los resultados muestran que estas organizaciones, a través, de sus diferentes stakeholders con una actitud ambiental, social y económica, interactúan entre sí e impulsan comportamientos que favorecen las estrategias circulares de reutilizar, reciclar, y compartir, en las tiendas solidarias. Estos hallazgos contribuyen a la literatura de EC en las organizaciones no gubernamentales y a la perspectiva de TPB al descomponer el constructo de actitud.
Patient adherence after coronary bypass grafting: different facets of same matter. A systematic review
Authors: Fofanova T. V. , Subotnikov M. V. , Ageev F. Т.
Published: August 2021

Background. Adherence in cardiological patients is a leading challenge due to a high society burden imposed by cardiovascular diseases (CVDs) through morbidity, reduced life expectancy, disability and high mortality rates in population. Despite the availability of highly effective medicines and high-technology care, the success of CVD treatment remains insufficient. A particular focus should be placed on patients with previous coronary artery bypass grafting (CABG).Objectives. A review of reasoning for non-adherence to medication and non-medication management in post-CABG patients and current methods influencing it.Methods. Russian-language and foreign literature was mined in the eLibrary and PubMed databases with the query keywords “medication adherence” [приверженность терапии], “coronary artery disease” [ишемическая болезнь сердца], “coronary artery bypass surgery” [коронарное шунтирование], “coronary revascularisation” [вторичная профилактика после коронарного шунтирования]. The review included papers published within 2016–2020, as well as selected relevant publications from 2003–2015, to cover 52 sources irrespective of study design and language. Content and descriptive analyses were used as research tools.Results. Coronary heart disease (CHD) poses an important health, social and economic problem worldwide as a leading cause of reduced life expectancy, disability and high mortality. Non-compliance with medication significantly bursts medical expenditures [1]. Coronary artery bypass grafting is used widely to treat multivessel coronary lesions both in stable and acute CHD. Secondary preventive techniques successfully preclude adverse post-CABG events, but adherence to post-CABG treatment is often low. The non-adherence rationale rarely links to a single factor but is rather complex and multifaceted. It includes social and economic reasons, systemic health care or personnel, therapy and patient-related factors. Methods are developing and refining to improve adherence to both non-medication and medication interventions.Conclusion. Clinical trials to improve secondary prevention adherence in patients after coronary artery bypass grafting will allow a wider implementation of relevant methods in outpatient management of this patient category.

Background. Contemporary dental diagnosis should supplement clinical examination with instrumental diagnostic techniques. Raman spectroscopy has become widely adopted due to high spatial resolution, non-invasiveness, the lack of strict requirements and ease of sample preparation.Objectives. A qualitative assessment of enamel mineral and organic composition dynamics using Raman spectroscopy.Methods. Raman spectroscopy was used as primary research method. The trial bench consisted of a Shamrocksr-303i high-resolution digital spectrometer with built-in DV420A-OE cooled optical detector (spectral range 200–1200 nm), RPB-785 optic fibre scattering probe integrated with LuxxMaster LML-785.0RB-04 laser source with wavelength 785 nm.Software spectrum processing was performed with Wolfram Mathematica 9. Spectra were denoised with a median filter (5 points), the approximating line (fifth order polynomial) of autofluorescent component was determined in 700–2200 cm-1 range using an iterative algorithm and then subtracted to receive isolated Raman spectra.Linear discriminant analysis (LDA) of data was performed with the IBM SPSS Statistics package. Results. The assay included 28 teeth, with 14 extracted for orthodontic indications and 14 — for chronic periodontitis. Spectral dental enamel dynamics has been established in periodontal disease and after the in-office bleaching procedure. The evidence obtained can be applicable in dental practice to verify patients at risk of periodontal disease by interpreting the tooth enamel spectral properties, as well as prior to in-office bleaching.Conclusion. We demonstrate high efficiency of Raman spectroscopy for qualitative assessment of the mineral and organic enamel composition dynamics in various settings. Raman spectroscopy is confirmed effective and versatile in various aetiologies. It was successfully applied to diagnose periodontitis by changes in the organic and mineral enamel composition and evaluate enamel after in-office bleaching.

В Калужской области в условиях инновационного развития животноводческой отрасли отмечено увеличение количества ферм с круглогодовым стойловым содержанием животных, которое требует качественных энергетических кормов собственного производства. В этом направлении актуально использование кукурузного корма в виде не только силоса, но и зерна. В результате многолетнего изучения в Калужском НИИСХ более 70 сортов и гибридов кукурузы зарубежной и отечественной селекции установлено, что в условиях области возможно выращивание кукурузы на силос, зерностержневую массу и зерно. Урожайность зелёной массы изучаемых гибридов составляла от 30 до 75 т/га, зерна — от 4 до 11 т/га. Произведён расчёт типовой научно обоснованной технологической карты возделывания кукурузы на зерно с последующим химическим консервированием плющеного зерна, показана экономическая эффективность технологии на примере Калужской области. Расчёты выполнены на основе использующихся в регионе технологий возделывания этой культуры и приготовления консервированного плющеного зерна в полимерном рукаве. При определении себестоимости продукции произведён расчёт потребности в денежных средствах по статьям затрат на выращивание кукурузы и приготовление её с помощью химического консервирования плющеного зерна. На основе полученных результатов установлено, что на производство 700 т плющеной консервированной кукурузы, при урожайности культуры 7 т/га, потребуется 5782,2 тыс. руб. (в ценах 2018 года). Для оценки вариабельности технологии с точки зрения рисков получения меньшей или большей урожайности нормативы затрат рассчитаны на 1 га и 1 т продукции при урожайности кукурузы на зерно 5, 7, 9 т/га. Полученные данные позволяют утверждать, что с ростом урожайности кукурузы от 5 до 9 т/га себестоимость 1 т продукции снижается с 11 405 до 6513 руб. (в ценах 2018 года).

The number of farms keeping livestock indoors all year round grew in the Kaluga region. Therefore, local forage production of high quality and nutrition became an important issue. Maize grain is a promising feed along with corn silage. Kaluga Agricultural Research Institute tested over 70 foreign and domestic maize varieties and hybrids for several years proving crop applicability for silage production, cob mass and grain. Hybrids produced 30‒75 t ha-1 of green mass and 4‒11 t ha-1 of grain. A flow chart for maize rolled grain conservation was developed; economic efficiency of the technology was proved. Calculations were performed according to regional technology of maize cultivation and rolled grain conservation in plastic bag. Prime costs for rolled grain conservation were evaluated. Production and conservation of 700 t of maize rolled grain requires 5782.2 rubles (2018) when crop yielding 7 t ha-1. To consider the risk of yield variation costs for 1 ha and 1 t of grain were calculated under grain productivity of 5, 7, 9 t ha-1. Yield increase from 5 to 9 t ha-1 reduces prime costs for 1 t of grain mass from 11 405 to 6513 rubles (2018).

During the past decade there has been a considerable increase in literature documenting the growth of Indian Ocean port cities. Famously described as the Brides of the Sea, port cities such as Cape Town, Karachi, Bombay (Mumbai), Madras (Chennai), Calcutta, Rangoon, Singapore, and Jakarta were the bridgeheads for the establishment of European dominance. They fostered greater connectivity and intercultural exchanges, and they produced distinctive urban settlement patterns, environments, and social relationships.
“Owned them like a Father": Labor Contractors, Port Workers, and the Makings of Ethnicity in Singapore
Authors: Yan Laura
Published: August 2021

Despite the importance of ports to the Indian Ocean world, labor contracting systems in ports remain understudied. By focusing on ethnic divisions of labor among port workers in colonial Singapore from the 1930s to the 1950s, this article shows how labor contractors constructed these divisions and how social organization in modern Singapore is rooted in labor contracting at the port. Past scholarship has explained merchants’ propensity to form partnerships within the same kin or ethnic circles with the notion of trust: that those of the same kin or ethnicity could be trusted more easily. However, this article argues that labor contractors often recruited migrant workers from the contractors’ home villages and regions because shared kinship and ethnicity allowed contractors to better control workers’ laboring, social, and cultural life. Performances of shared kinship and ethnicity gave contractors power as both employers and community leaders. After World War II, port workers also solidified ethnic divisions by organizing into unions along the lines of ethnicity, and they secured benefits as ethnic blocs, rather than for all port workers. This post-war moment of organizing labor by ethnicity has shaped labor activism in Singapore today as migrant workers continue to strike in ethnic blocs to protest disparities in working conditions between workers of different ethnicities.
A methodological examination of multidisciplinary research of mak yong theatre: text, heritage, and performance | Pemeriksaan metodologis atas pendekatan multidisipliner dalam kajian tentang teater mak yong: teks, warisan budaya, dan pertunjukan
Authors: Darmawan Alan
Published: August 2021

Previous studies of mak yong theatre in Indonesia looked at the art form as a given tradition, and described its elements and performance structure. Such an approach is inadequate to investigate mak yong in the current social and cultural context. State institutions, the local government, communities, performers, and other agents have revived and constantly (re)shaped mak yong theatre and its presentation as a commodified Malay identity marker. Heritage formation, local identity politics, and tourist festivals promoted mak yong as a revived traditional form of theatre practice, an intangible heritage, and a stage performance. So how should the above aspects be approached and the social processes that shape them disentangled? This article examines the relevance of multidisciplinary approaches and demonstrates how the perspectives of anthropology, heritage studies, and philology work in studying mak yong and its current production in the Riau Islands. Kajian terdahulu tentang teater mak yong di Indonesia umumnya melihat kesenian ini sebagai tradisi yang “demikian adanya”, dan mendeskripsikan elemen dan struktur pertunjukannya. Pendekatan semacam ini tidak lagi memadai untuk menelaah mak yong dalam konteks sosial dan budaya saat ini. Mak yong disajikan sebagai tradisi yang dibangkitkan kembali dan senantiasa dibentuk ulang oleh lembaga negara, pemerintah lokal, komunitas, aktor, dan pelaku-pelaku lainnya, sebagai satu di antara penanda identitas Melayu yang dikomodifikasi. Pelembagaan warisan budaya, politik identitas lokal, dan pariwisata budaya memajukan mak yong sebagai tradisi yang dihidupkan kembali, warisan budaya takbenda, dan pertunjukan panggung. Lantas, bagaimana menelaah aspek-aspek di atas dan mengurai proses sosial yang membentuknya? Artikel ini menguji relevansi pendekatan antropologi, heritage studies, dan filologi, dan menunjukkan cara bekerjanya dalam mengkaji mak yong dan produksinya saat ini di Kepulauan Riau.

Aim: The natural course of sarcoidosis is heterogeneous. There is no clear marker that can predict the course of this disease and its characteristics over months/years. We aimed to analyze our patients' data to identify a prediction parameter at admission.Methods: The patients with sarcoidosis and followed-up between 01/01/2015 and 31/12/2020 comprised the study group. The patients were staged by a Scadding staging system. Improvement or deterioration in at least two of the clinical-laboratory-radiological parameters indicates regression, stable disease, progression, or relapse of sarcoidosis.Results: The study group comprised 4 cases (6.9%) defined as stage 0; 15 cases (25.86%) as stage 1; 39 cases (67.24%) were defined as stage 2. The mean age at diagnosis was 40.84±13.56 in stage 0 + stage 1 group, while it was 48.05±13.36 in the stage 2 group (p=0.06). 74.1% of the cases were women. The female/male ratio was found at 2.86. 57 out of 58 cases had a pathological diagnosis (EBUS TBNA). While PFTs values and DLCO were significantly lower at advanced stages but the same statistical significance was not identified between these values and the clinical course of the disease. As a result of the multivariate analysis, it was observed that only the presence of chest pain at admission affected the progression of the disease in the follow-up period.Conclusion: Sarcoidosis is a multi-systemic disease and there is no clear finding for predicting the poor prognosis of the disease. We conclude that chest pain symptom at admission is valuable predictive finding and can be used as a clue for the progression at follow-up.
