Актуальность исследования обусловлена раскрытием возможности определения связей Si с C, H, N, O в структурах газово-жирных углей и других углефицированных веществ методом инфракрасной спектроскопии диффузного отражения в диапазоне 7500–350 см–1 с последующей обработкой спектров и определением спектральных характеристик, расчетом значений для определения структурно-генетических показателей и выполнения структурно-группового анализа. Использование структурно-генетических показателей: Пм, Пв, ПVt+L, ПI, Пг, позволяет определять влияние генетических факторов на образование разных типов связей кремния и их количества в структурах природных органических веществ. Цель: на примере инфракрасных спектров углей пластов газово-жирной стадии углефикации показать приёмы определения типов связей Si с элементами C, H, N, O с помощью справочных спектрометрических характеристик простых химических соединений кремния и анализа парной корреляции значений интенсивности выбранных полос диффузного отражения с содержанием Si в углях; также на примере веществ фоссилизированных (гербарий, фитолейма) и углефицированных (торф, кероген, уголь) показать применение обнаруженных типов связей кремнийорганических соединений в структурах природных органических веществах и характер их изменения в зависимости от углепетрографических и структурно-генетических показателей. Объекты: угли пластов Жерновского месторождения Кузбасса; образцы гербария хвоща болота Томской области, фитолейм хвоща, папоротника и керогена нефтегазовых отложений Западной Сибири юрского возраста, торфа месторождения Апача на Камчатке, каменных углей марки Д пласта Двухаршинного Черногорского месторождения Минусинского бассейна и марки Ж пласта 39 Жерновского месторождения Кузбасса. Методы: инфракрасная спектроскопия диффузного отражения в диапазоне 7500–350 см–1 с Фурье-преобразованием и приставкой DRS-8010ASC, химический анализ золы углей, углепетрографический анализ мацерального состава углей. Результаты. Установлено, что с помощью справочных таблиц спектрометрической характеристики кремния и его корреляции с интенсивностью диффузного отражения на частотах с волновыми числами 800, 855, 868, 2070, 3391 см–1 хорошо диагностируются соединения Si–H, SiCH3, Si(CH3)2, Si(C≡CH)4, Si2NH соответственно. В частности, они отражают разные виды связей Si с функциональными группами и, как показал эксперимент, с образцами гербария хвоща, фитолеймов хвоща и папоротника, керогена, торфа, каменных углей марок Д и Ж. Их использование со структурно-генетическими показателями – Пм, Пв, ПVt+L, ПI, Пг – позволяет определять влияние генетических факторов на образование разных типов связей кремния и их количества в структурах природных органических веществ.

Актуальность. При разработке новых методов объемного моделирования вещественного состава геологических сред по данным скважинных и наземных наблюдений ранее авторы выдвинули предположение о возможности альтернативной оценки ошибки с помощью множителя Лагранжа. На практике, в силу малого количества скважинных измерений и большого расстояния между скважинами, важно не только использовать эффективную модель среды, но и оценить ее точность в межскважинном пространстве. Использование простых и понятных оценок точности моделирования является залогом снижения рисков принятия неверного решения по последующему бурению. Метод неопределенных множителей Лагранжа используется при решении экстремальных задач с ограничениями типа равенства. В таких науках, как экономика, статистическая и классическая механика в множители Лагранжа вкладывается экономический или физический смысл, и он приобретает практическое значение. Однако в геостатистике при решении задачи выбора оптимальных методов интерполяции пространственных данных от множителя Лагранжа избавляются на первых этапах решения систем линейных уравнений. В связи с этим отсутствуют как аналитические, так и прикладные исследования его значения. Цель: выяснить смысл множителя Лагранжа при решении систем ординарного и двойного кригинга; разработать новые способы получения нормированных оценок ошибки геостатистического моделирования; провести исследования полученных выражений на реальных материалах, а именно, при решении задач прогноза вещественного состава геологических сред.Методы: ординарный кригинг, двойной кригинг, метод неопределенных множителей Лагранжа, метод Крамера.Результаты. Для проведения исследований предложено в модель набора известных значений прогнозируемого параметра добавить неизвестную составляющую. На основе этой модели проведены аналитические и численные исследования, которые привели к новым выражениям, связывающим вес неизвестной составляющей и ковариационные свойства измерений с множителем Лагранжа. Предложены оценки весовой функции неизвестной составляющей. На примере реальных данных для решения задачи прогноза вещественного состава геологических сред показана практическая значимость множителя Лагранжа при анализе ошибок моделирования.

Актуальность. Отходы ОАО «Байкальский ЦБК» несут реальную угрозу возникновения социально-экологической катастрофы озера Байкал и всего Южного Прибайкалья, поэтому особенно остро стоит проблема разработки комплексных решений по ликвидации накопленных лигнинсодержащих отходов. Одним из перспективных направлений переработки такого типа отходов можно считать использование естественных природных процессов, например вымораживание в зимний период времени года вследствие отрицательных температур или самозарастание вследствие естественных процессов сукцессии. Цель: разработать экологически безопасную технологию переработки коллоидных лигнинсодержащих отходов целлюлозно-бумажной промышленности. Методы: опытно-промышленные испытания на Солзанской промплощадке ОАО «Байкальский ЦБК» по вымораживанию лигнинсодержащих отходов и получению из них почвогрунтов путем смешивания с добавками; выполнение количественного химического анализа с использованием методов атомно-абсорбционной и атомно-эмиссионной спектрометрии, высокоэффективной жидкостной хроматографии, токсикологического анализа. Результаты. Опытно-промышленные испытания показали, что после вымораживания происходит разрушение коллоидной структуры лигнинсодержащих осадков с уменьшением объема до 40 %, влажности до 60 %, а также со снижением токсичности с третьего (умеренно опасные) в четвертый (малоопасные) и пятый класс (практически неопасные) опасности отходов в зависимости от его состава. После вымораживания полученный осадок при внесении различных добавок (золы ТЭЦ, осадок канализационных очистных сооружений) можно применять как почвогрунты и удобрения для рекультивации нарушенных земель и выращивания сельскохозяйственных культур. Таким образом, разработана экологически безопасная технология переработки отходов целлюлозно-бумажной промышленности с получением почвогрунтов, которая является малоэнергозатратной и не содержит дорогостоящего импортного оборудования.

Published: August 2022

Background: Tharparkar is one of the important milch breed of cattle for the arid western region of India, which has the capacity to withstand harsh desert climatic conditions and has high thermo-tolerance gene (Bhat et al. 2016) with better reproductive efficiency and milk production. Methods: The present investigation was undertaken on 422 lactation record of 95 cows spread over 30 years from 1990 to 2020, available at ICAR-Central Arid Zone Research Institute, Jodhpur (Rajasthan). Various lactation and reproduction traits in Tharparkar cattle were analysed by using Linear Mixed Model methodology. Result: The overall least-square means were 1803.05±31.59 litre for 305-days lactation yield, 1915.38±36.87 litre for total lactation yield (TLY) in 313.12±4.28 days of lactation length (LL). The peak yield (PY) was 10.29±0.12 litre and days to attain peak yield was 68.12±2.16 days of calving. The least-square means of dry period (DP) and calving interval (CI) were 114.23±4.81 and 427.01±5.49 days, respectively. Significant improvement in production and reproduction traits was observed may be due to selection of high yielding animals and improving management condition of herd. Rigid culling of animals should be followed after 5th lactation onwards to make the dairy farm profitability. Non-significant effect of season of calving indicated the adaptive character against the extreme climatic conditions of the arid zone.

Aim: Balloon kyphoplasty is a popular minimally invasive technique for vertebral fractures. Although vertebral fractures occur mostly in the thoracolumbar region, compression fractures can be seen in the entire vertebral column. The mid-thoracic levels are difficult areas in terms of complications in minimally invasive procedures. Our study aimed to examine the effect of balloon kyphoplasty on vertebral height, kyphosis angle, and cement leaks as a complication in mid-thoracic vertebral fractures.
Materials and Methods: Radiological images, patient files, and pathology results of patients who underwent kyphoplasty due to a single or multiple mid-thoracic vertebral fractures between 2017 and 2020 were retrospectively analyzed.
Results: A total of 19 patients (9 males and 10 females) and 28 operated vertebrae were included in the study. The mean age of the patients was 58.42±18.79 (23-86) years, and the mean operation time was 40.18±15.01 minutes (17-99). The amount of cement used during the procedures was 3.68±1.13 mL (1.5-7), and postoperative cement leakage was observed in 12 levels (42.9%). Anterior and median vertebral heights and kyphosis angle improved significantly compared to preoperative values (p

Published: August 2022

SummaryCarbon dioxide (CO2) injection into a deep saline aquifer can dissolve into formation brine and generate carbonic acid. The resulting acid can drive fluid-rock geochemical reactions. The impact of these fluid-rock geochemical reactions on porosity, permeability, and multiphase flow responses is relevant to the determination of CO2 storage capacity of deep saline aquifers. In this research, carbonic acid flooding experiments were performed on core samples consisting of poorly sorted, quartz-rich sand with laminated bedding from a possible CO2 storage target in northwest Wyoming. Complementary pre- and post-injection porosity and permeability, thin-section, Brunauer-Emmett-Teller (BET) surface area, mercury intrusion capillary pressure (MICP), and time-domain nuclear magnetic resonance (TD-NMR) measurements were conducted. Overall, both core porosity and permeability increased after a 7-day carbonic acid injection, from 6.2 to 8.4% and 1.6 to 3.7 md, respectively. We attributed these changes to carbonate mineral dissolution, which was evidenced by the effluent brine geochemistry, pore-throat size distribution (PTSD), and BET surface area. To be more specific, within the more-permeable section of core samples containing larger pore size, the permeability increment is apparent due to dolomite mineral grains and cements dissolution. However, for the lower-permeability section corresponding to the smaller pore size, mineral precipitation possibly lessened dissolution effects, leading to insignificant petrophysical properties changes. Consequently, the observed heterogeneous carbonic acid-rock interactions resulted in alterations of CO2/brine relative permeability (i.e., the initial CO2 saturation decreased and the CO2 flow capacity was enhanced). This research provides a fundamental understanding regarding effects of fluid-rock reactions on changes in static and multiphase flow properties of eolian sandstones, which lays the foundation for more accurate prediction/simulation of CO2 injection into deep saline aquifers.

Published: August 2022

Abstract
Introduction: Two of the most challenging viruses for vaccine development are SARS-COV-2 causing the current COVID-19 pandemic and influenza virus (H1N1) which spread annually causing seasonal epidemics or increase the pandemic risk. In this study, we analyzed the immonodominant epitope regions in Fusion peptides consisting of the Spike_S1_ N-terminal domain from SARS-COV-2 in-frame to hemagglutinin H2 (HA2) gene from Influenza A virus (H1N1) and also Human IFNɣ gene by two (G4S)3 linker. Method: The comprehensive analysis based on Immunoinformatic has been conducted on prediction servers to predict T and B cell epitopes. In silico cloning and expression in pET-28(+) expression vector and vaccine optimization were assessed. The overall model quality were accessed and the docking or binding affinity of designed vaccine to the Toll-like receptor 3 (TLR3) were analyzed. The efficiency of the constructed vaccine confirmed by appropriate expression of designed vaccine candidate tested by in silico cloning in pET–28(+) vector and codon optimization might increase the production of vaccine candidate into Escherichia coli strain k12. Result and discussion: In conclusion, we suggest that this fusion peptide would be an attractive design strategy toward developing bivalent vaccine against both COVID-19 and Influenza as promising vaccine candidate without need to reformulation or vaccination each year. Our study is not a clinical study and there is no need to have a Trial Registration Number (TRN)

Abstract
Background: The essential oil of pistacia vera (cv. Ohadi) hull (PHEO) was checked using gas chromatography mass spectrometry (GC/MS) analysis. It was studied the genes of the wnt pathway with a certain concentration of PHEO on Human gastric cancer (AGS), human hepatocellular carcinoma (PLC/PRF/5), and human colon cancer (CACO2) cell lines. Methods and Results: After evaluating the survival rate of cancer cells by MTT test and determining IC50, pistachio hull essential oil (PHEO) was used for 24-hours to treat the cells. After RNA extraction, the expression of wnt pathway genes was evaluated by Real-Time PCR. Considering the crucial role of beta-catenin accumulation and its effect on the progression of gastrointestinal cancers, Western blot analysis was also used to determine the effect of PHEO in protein expression of β-catenin inhibition. Also, an in silico analysis was carried out to investigate the effect of PHEO extracted compounds on protein expression of β-catenin and FZD7 inhibition. According to the results, wnt pathway genes were changed in samples treated using PHEO. The results showed the up-regulation of GSK-3β and down-regulation of Wnt-1, LEF-1, TCF1, and CTNNB1 genes compared to the control. Conclusion: We showed inhibition of β-catenin protein in cancer cell lines. Four compounds of PHEO were suggested to have an inhibition effect on β-catenin and FZD7. These compounds can be useful in the treatment of gastrointestinal cancers. Altogether, the inhibitory role of β-catenin protein can be very effective and can be considered one of the therapeutic goals in the treatment of gastrointestinal cancers.

Abstract
To meet the higher requirements intelligent and electric trend of automobile puts forward for brake-by-wire system, the master cylinder pressure estimation and control is the core technology that need to be researched and improved. Most of the existing research about master cylinder pressure control is based on pressure sensor equipped in it. In this scheme, the failure of pressure sensor will seriously affect the reliability and it is difficult to ensure pressure tracking speed and accuracy at the same time. This article proposes an adaptative pressure estimation and control architecture which is based on estimated pressure instead of pressure sensor for integrated electro-hydraulic brake system. About the master cylinder pressure estimation, we propose an adaptative fusion method which calculates the weights of estimator based on vehicle mode and electro-hydraulic mode according to master cylinder pressure, longitudinal speed and ABS status, the estimated pressure from fusion method finally is used to update the hydraulic mode of integrated electro-hydraulic brake system. According to the updated hydraulic mode, we can derive the final estimated pressure and update the coefficient of the friction mode. In addition, this article proposes an adaptative LQR controller for master cylinder pressure control which uses fuzzy-logic controller to adjust the weights of LQR controller based on target pressure and difference compared with actual pressure. At last, through Mode-in-Loop and Hardware-in-Loop tests, we compare the estimated pressure and actual pressure, pressure tracking results of Piecewise PID controller and that of adaptative LQR controller in ramp, step and sinusoidal response. Based on the analysis of experiment results, we can conclude that the proposed adaptative pressure estimation and control architecture can estimate MC pressure effectively in any scene and ensure the pressure tracking speed and accuracy at the same time.
The Impact of Hydrogen Energy Storage Aqua Electrolyzer Fuels Cell on Automatic Generation Control of Power System using optimal fuzzy PI controller
Authors: Rai Ankur , DAS DUSHMANTA KUMAR KUMAR 
Published: August 2022

Abstract
The influence of energy storage hydrogen aqua electrolyzer (HAE)-fuel cell (FC) units on automated generation control (AGC) of linked power systems is investigated in this study. In today's fast-paced world, AGC plays a critical role in ensuring that the power supply meets high-quality requirements. This study proposes a novel fuzzy gain scheduling (FGS) PI controller as an intelligent control approach for enhancing AGC power system performance with or without HAE-FC units. The FGS-PI controller's input scaling factors (SFs) and output SFs are tuned using a class topper optimization. The suggested FGS-PI controller's sensitivity analysis is shown to evaluate its performance. Due to changes in system parameters and multi-step load disturbances, the suggested controller performs well.

Abstract

This paper presents the comparative analysis of the properties of highly dispersed silicas synthesized by pyrogenic and fluoride methods. Raw materials and synthesis conditions differ significantly for the considered methods. The structure and surface properties of synthesized silica samples was characterized by a number of methods such as IR, nitrogen adsorption, SEM, microcalorimetry, temperature programmed desorption time-of-flight with mass-spectrometry (TPDM), thermogravimetric analysis. IR spectra showed presence of characteristic absorption bending bands at 468 сm− 1 (Si-O-Si) and at 800 сm− 1 (O-Si-O) and stretching vibrations bands in the range of 1000–1200 сm− 1 (Si-O-Si) for all the studied samples regardless of their synthesis method. The absorption band at 3750 cm− 1 attributed to free silanol groups ≡ Si-OH confirms the presence of this main sorption centers evenly distributed on the surface for all silica samples. The intensity of this band is quite low for samples obtained by the fluoride synthesis method due to the high water content. This fact is also confirmed by the TGA and TPDM methods. The distribution functions of the activation energy of water desorption demonstrates several maxima: (i) at 60–80 kJ/mol and 100 kJ/mol refers to desorption of molecularly adsorbed water; (ii) at 160–180 kJ/mol is due to the associatively desorbed water. All studied silica samples are hydrophilic according to values of the heat of immersion in water and n-decane, and their Rebinder’s hydrophilicity index Kh > 1. The BET surface area and pore volume of samples significantly depend both on the method of synthesis and on the raw materials.
