Utility of oral mucosa as a substrate for the serodiagnosis of pemphigus: A descriptive analysis
Authors: Jindal Anuradha , Rao Chythra , Pai Satish B. , Rao Raghavendra 
Published: August 2021

Background:
The indirect immunofluorescence test is useful in the serodiagnosis of pemphigus. As indirect immunofluorescence titers correlate with disease activity in pemphigus, it is often used as a monitoring tool. The sensitivity of indirect immunofluorescence depends on the substrate used, and the preferred substrates are monkey esophagus for pemphigus vulgaris and normal human skin for pemphigus foliaceus.

Aims:
We evaluated oral mucosa as a substrate for indirect immunofluorescence in pemphigus.

Methods:
Fifty patients with pemphigus (40 with pemphigus vulgaris and ten with pemphigus foliaceus) and 50 controls were enrolled for study. Demographic and clinical details were recorded and indirect immunofluorescence using two substrates (oral mucosa and normal human skin) was carried out in serial dilution. Desmoglein (Dsg) 1 and 3 enzyme-linked immunosorbent assay was also evaluated simultaneously.

Results:
Indirect immunofluorescence was positive in 40 patients (80%) with oral mucosa substrate and 34 patients (68%) with normal human skin substrate. Circulating antibodies were detected with oral mucosa in 33 (82.5%) of the 40 pemphigus vulgaris patients and in 26 (65%) patients using normal human skin. Antibodies were detected in eight of the ten pemphigus foliaceus patients (80%) with normal human skin and in seven (70%) patients with oral mucosa. Dsg enzyme-linked immunosorbent assay was positive in 45 (90%) patients, and 37 of these were also indirect immunofluorescence positive with oral mucosa. In the five Dsg enzyme-linked immunosorbent assay-negative patients, indirect immunofluorescence with oral mucosa was positive in three.

Limitations:
A comparison of oral mucosa with monkey esophagus could not be performed.

Conclusion:
Oral mucosa is a suitable and sensitive substrate for indirect immunofluorescence in pemphigus. Further studies comparing the sensitivity of indirect immunofluorescence using oral mucosa with monkey esophagus are recommended.

Abstract

Bridge inspection aims to determine the condition of the bridge, so that the bridge manager can determine the appropriate action. Bridge inspection using the INVI-J application makes it easy to implement and store data, but requires a quality assurance and quality control. In this study, data from questionnaires and interviews were used to complete the quality assurance and quality control of bridge inspections with the INVI-J application in the regions of Central Java and the Special Region of Yogyakarta. The results of the evaluation of the audit report data showed 95% for completeness of the data, 33% for the suitability of the documentation, and 78% for the suitability of the examination results. Evaluation of the field inspection gives a conformity value of 47% at level 1 and 40% at level 2. Evaluation of the inspection report data provides a higher level of conformity than the evaluation of independent inspection data.

Keywords: bridge inspection; INVI-J application; quality assurance; quality control.

Уже в ближайшем будущем от использования современных численных методов расчета будет зависеть прогресс в области проектирования оснований и фундаментов зданий и сооружений, поскольку возможности по совершенствованию строительных норм практически исчерпаны. Целью статьи является демонстрация возможностей численных расчетов с использованием современных моделей грунта на примере проектирования фундамента стандартного нефтяного резервуара для хранения нефти и нефтепродуктов. Приведено сравнение результатов расчетов осадки основания резервуара емкостью 30 000 м, выполненных в соответствии с действующими нормами проектирования и методом конечных элементов с применением программного комплекса PLAXIS. В частности, проведены численные расчеты с использованием современных моделей грунта: 1) модели грунта с упрочнением (Hardening Soil model, HS); 2) модели грунта с упрочнением и учетом малых деформаций (Hardening Soil small strain model, HSs). Показано, что использование указанных моделей при наличии требуемого объема исходных данных позволяет существенно уточнить вычисления, выполняемые по нормативным методикам. С учетом полученных результатов определена возможность оптимизации проектных решений при выборе типа фундамента резервуара.
In the near future, the progress in design of bases and foundations of buildings and structures will depend on the use of modern numerical calculation methods since the opportunities to improve the building regulations are almost exhausted. This article aims to demonstrate the capabilities of numerical calculations with the use of modern soil models on the example of designing the foundation of a standard oil storage tank for crude oil and petroleum products. This article provides a comparison of the results of the base settlement of a 30,000 m tank calculations made in accordance with the current standards of design and the finite elements method with the use of the PLAXIS software package. In particular, the following numerical calculations with the use of modern soil models have been performed: 1) Hardening Soil model, HS; 2) Hardening Soil small strain model, HSs. It is shown that the use of these models in the presence of the required amount of baseline data can significantly refine the calculations performed according to normative methods. Considering the obtained results, the possibility of optimizing design solutions when selecting the type of foundation of a tank was determined.
Methodology for criteria-based assessment of energy efficiency of main pipeline pumps
Authors: Рябцев Егор Андреевич 
Published: August 2021

В настоящее время об энергоэффективности насосного агрегата судят на основании результатов приемо-сдаточных испытаний - по значению КПД в номинальной рабочей точке. Опыт эксплуатации насосов на объектах нефтепроводного транспорта показывает, что реальная рабочая точка насоса отличается от номинальной. Данное расхождение объясняется вариативностью режимов работы насосных установок. В этой связи предлагается оценивать энергоэффективность насоса по результатам испытаний исходя из реальных условий функционирования насосного оборудования - в рабочем диапазоне, необходимом для перекачки нефти (нефтепродуктов) с учетом изменения потребной подачи и напора гидросистемы. Существующие методики оценки энергоэффективности насосов в рабочем диапазоне имеют ограничения для применения на объектах магистральных нефтепроводов. В настоящей работе предлагается использовать с этой целью критериальную оценку по характерным точкам в диапазоне подач. Сформулированы основные положения разработанной методики. Сделан вывод о том, что ее применение при приемо-сдаточных испытаниях позволит улучшить качество оборудования, поставляемого на производственные объекты, а следовательно, энергоэффективность НПС.
Currently, energy efficiency of a pumping unit is assessed based on the acceptance test results according to the efficiency value at the nominal working point. The experience of operating pumps at oil pipeline transportation facilities shows that the actual working point of the pump differs from the nominal one. This discrepancy is explained by the variability of the pumping unit process modes. In this connection, it is proposed to evaluate pump’s energy efficiency based on the test results under the actual operating conditions of the pumping equipment, in the operating range required for pumping oil (petroleum products), taking into account the change in the required supply and hydraulic system pressure. The existing methods for assessing energy efficiency of pumps in the operating range have limitations for use at main oil pipeline facilities. This study proposes to use a criteria-based assessment using characteristic points in the supply range for this purpose. The basic principles of the developed method are formulated. It is concluded that its application during the acceptance tests will improve the quality of equipment supplied to production facilities, and hence the PS energy efficiency.

В условиях существующего многообразия автоматизированных систем управления технологическими процессами (АСУТП), возрастающих рисков компьютерных инцидентов, обусловленных развитием информационных технологий, неизменно актуальными являются вопросы повышения качества программного обеспечения (ПО) АСУТП. В настоящей статье на примере АСУТП организаций системы «Транснефть» представлена возможность использования методов статического анализа исходного кода ПО с целью обеспечения информационной безопасности АСУТП. Рассмотрены причины низкого качества ПО и подходы к его повышению. Проанализированы методы анализа исходного кода ПО (статический, динамический, интерактивный), сделан вывод о том, что наиболее перспективной является комбинация трех видов статического анализа: сигнатурного анализа, анализа потока управления, анализа потока данных. Указанная комбинация легла в основу методики выявления ошибок, потенциально опасных конструкций, логических бомб и неиспользуемых переменных в ПО АСУТП, разработанной в рамках научно-исследовательской работы «Создание системы анализа исходного кода программного обеспечения автоматизированных систем управления технологическими процессами». Основным достоинством созданной методики является ее инвариантность по отношению к языкам программирования и разновидностям дефектов. При этом общий алгоритм поиска дефектов остается неизменным: меняются только сигнатуры, правила выявления.
With the existing variety of automated process control systems (APCS) and the increasing risks of computer incidents caused by the development of information technology, the issues of improving the quality of the APCS software are invariably topical. This article presents the possibility of using the software source code static analysis methods for ensuring the information security of the APCS using the example of Transneft system entities’ APCS. The reasons for the low quality of software and approaches to its improvement are considered. Methods of software source code analysis (static, dynamic, interactive) are analyzed, and it is concluded that the most promising is a combination of three types of static analysis: signature analysis, control flow analysis, data flow analysis. This combination serves as the basis for the methodology of detecting errors, potentially dangerous structures, logic bombs, and unused variables in the APCS software developed as part of the research work entitled “Creation of a System for Analyzing the Source Code of Automated Process Control System Software”. The main advantage of the created methodology is its invariance with respect to programming languages and types of defects. At the same time, the general defect searching algorithm remains unchanged: only signatures and detection rules are subject to change.

Abstract The development of technology which is increasingly rapid nowadays certainly has a positive and negative impact on student development, especially on character development. The role of integration character education is very needed as an effort to overcome this. So far, character education is identical to the subject of Religion or Pancasila Education only. However, the development of time, the integratio of character education can be integrated with the entire learning process, including the learning process of mathematics. Teachers play an important role in this. Teachers can become facilitators and role models in providing role models in behavior, attitudes, and speech related to cultivating student character. Teachers can also develop and instill character education in the learning process from the planning stage to the evaluation stage. The use of models, strategies, and learning approaches can help teachers instill character values. One approach that can be used is to use mathematic problem solving which includes several steps to solve it, namely (1) understanding the problem, (2) planning for problem solving, (3) solving results and (4) checking the answer again.

ABSTRACT
Wild, diploid Arachis species are a great source of biotic and abiotic stress resistances and tolerances for peanut breeding programs; however, these species also have undesirable characteristics such as small seed size, low yield, and weak peg strength. Peg strength has been shown to have a positive, linear relationship with yield in cultivated peanut. Therefore, the weak peg strength of wild Arachis species could be detrimental to yield and needs to be selected against when introgressing useful alleles from wild species into elite germplasm. To enable breeders to effectively utilize these wild species, we sought to characterize peg strength and anatomical characteristics correlated with peg strength in seven diploid Arachis species, as well as four allotetraploids, six (cultivated peanut lines x allotetraploid) F1 hybrids, and two cultivated peanut breeding lines. For each genotype, five mature pegs were tested for peg strength and cross-sections for three of the five pegs were subsequently taken and analyzed for peg anatomical characteristics including total peg cross-section area, mean bundle cap area, total bundle cap area, bundle cap as a percentage of peg area, bundle cap number, mean distance between bundle caps, total distance between bundle caps, and tannin cell count. Genotype was a significant indicator for peg strength and all the anatomical characterization parameters (P &lt; 0.05). Peg strength was positively and highly correlated with peg area, mean bundle cap area, total bundle cap area, and bundle cap number. Peg strength comparable to that of peanut breeding lines was recovered in the F1 hybrids. Because weak peg strength in the wild species appears to be recessive, strong pegs can likely be easily selected during the process of introgression.
