Authors: Рогатнев Ю. Ф. , Панфилов Д. В. , Соколов О. О. 
Published: June 2022

Постановка задачи. Рассмотрен вопрос определения несущей способности по наклонным сечениям двухслойных изгибаемых элементов таврового сечения с высокопрочным бетоном в сжатой зоне. Нормативная документация по расчету и проектированию железобетонных конструкций не учитывает свесы полок таврового сечения при определении несущей способности. В связи с этим поставлена задача определить влияние механических характеристик бетона свесов полки на несущую способность элементов. Рассмотрены элементы без поперечного армирования и с различными классами бетона в полке. Результаты. По результатам численного моделирования установлены характерные картины напряженно-деформированного состояния при исчерпании несущей способности элементов. Приведены зависимости несущей способности от пролета среза и класса бетона полки на сжатие. Получены значения несущей способности элементов без учета свесов полки по СП 63.13330.2018 и EN 1992-1-1. Выводы. Установлено, что вопреки логике нормативной документации СП 63.13330.2018 и EN 1992-1-1 свесы полки балки таврового сечения влияют на несущую способность элемента по наклонному сечению. При этом повышение физико-механических свойств бетона отдельно полки двухслойного элемента образует еще большие запасы несущей способности.
Statement of the problem. An issue of identifying the load-carrying capacity by bending sections of a facing section with high-strength concrete in the compressed zone is investigated. Normative documentation for calculating and designing ferroconcrete structures does not account for curvatures on shelves of a facing section while identifying the load-carrying capacity. Therefore we must determine the impact of mechanical characteristics of concrete in curvatures on the load-carrying capacity of the elements. Elements without a transverse section and using various concrete types in a shelf are considered. Results. According to the results of numerical modelling, typical patterns of the stress-strain as the load-carrying capacity diminishes are identified. Dependencies of the load-carrying capacity on the span of a curvature and concrete type in compression are presented. The load-carrying capacity of the elements with no account of curvatures in a shelf are obtained in compliance with SP 63.13330.2018 and EN 1992-1-1. Conclusions. It was found that in contrast to the normative documentation SP 63.13330.2018 and EN 1992-1-1 curvatures on a shelf of a girder of a facing section affects the load-carrying capacity of an element by a bending section. An increase in the physical and mechanical properties of concrete in relation to a shelf of a two-layer element generates extra load-carrying capacity.

Published: June 2022

Постановка задачи. Проанализировать результаты лабораторных испытаний сваи с присоединенной к ее стволу консолью разной длины при горизонтальных нагрузках и сравнить их с результатами испытаний одиночной сваи. Результаты. В ходе лабораторных испытаний было установлено, что присоединенная к стволу сваи консоль увеличивает несущую способность сваи в среднем в 1,5 раза. При этом оптимальной следует признать консоль длиной 1,5 d , где d - диаметр сваи. По результатам экспериментальных исследований взаимодействия свай с песчаным основанием были определены горизонтальные и вертикальные перемещения головы сваи, а также угол поворота головы сваи, при этом показано, что наличие консоли приводит к уменьшению горизонтальных перемещений и крена сваи в 4 раза. Выводы. Результаты приведенных лабораторных испытаний наглядно показали, что при присоединении к свае консоли перемещения сваи становятся существенно меньше, чем ее перемещения без данного элемента. Кроме того, результаты опытов показали эффективность применения консолей с целью повышения несущей способности горизонтально нагруженных свай.
Statement of the problem. We have analyzed the results of laboratory tests of a pile with a console of different lengths attached to its shaft under horizontal loads and compare them with the results of testing a single pile. Results. During laboratory tests, it was found that the console attached to the pile trunk increases the bearing capacity of the pile by an average of 1.5 times. At the same time, the console with a length of 1.5 d should be considered optimal, where d - is the diameter of the pile. According to the results of experimental studies of the interaction of piles with a sandy base, horizontal and vertical movements of the pile head were determined, as well as the angle of rotation of the pile head, while it was shown that the presence of a console leads to a decrease in horizontal displacements and the roll of the pile by 4 times. Conclusions. The results of the above laboratory tests clearly showed that when the console is attached to the pile, the displacement of the pile becomes significantly less than its displacement without this element. In addition, the results of the experiments showed the effectiveness of the use of consoles in order to increase the non-existent capacity of horizontally loaded piles.

Big data analytics can extract travelers' sentiment, emotions, and experiences from their internet opinions. This study analyzes sentiment, emotion, and traveler experiences at eight tourism destinations in Purwokerto Central Java, Indonesia. The methods are lexicon using NCR vocabulary(EmoLex) and word cloud analysis. The results show visitors generally have a positive sentiment. The five destinations with high positive sentiment are the Village (91%), Lokawisata Baturaden(81%), Baturaden Forest (79%), Limpa Kuwus (78%), and Taman Andang(.77%). In comparison, other destinations achieve positive sentiment under 70%. Only a few visitors give negative sentiment to all tourism destinations. The emotion of visitors stands out in Joy and Trust. NRC revealed sadness dan anger emotion but only about 20%. Cloud analysis does not reveal a distinguish keyword because the word feature still contained noise such as conjunction, adverb, and the name of the sites. Further research must consider other text preprocessing to handle noises.

Covid-19 merupakan sejenis virus dari family corona viridae yang menyebabkan penyakit menular dan mematikan yang menyerang manusia pada saluran pernapasan hingga ke paru-paru. Pada umumnya pengidap covid-19 akan mengalami gejala awal berupa deman, sakit tenggorokan, pilek dan juga batuk-batuk bahkan sampai parah dapat menyebabkan pneumonia. Virus ini dapat menular melalui cairan pernafasan yang keluar dari tubuh penderita saat batuk atau mengeluarkan ludah dan riyak. Banyak negara melakukan kebijakan yang diterapkan di dalam wilayahnya. Seperti sistem kebijakan lockdown, atau social distancing terhadap masyarakat. Itu sebabnya pemerintah Indonesia saat ini mengimbau serta mengingatkan kegiatan dari social distancing. Secara khusus yaitu mengenai bagaimana negara merespons dan berupaya mencegah dan menghentikan penyebaran virus jauh lebih luas. Beberapa negara menunjukkan keberhasilan, tetapi ada pula yang menunjukkan kegagalan dari kebijkan tersebut. Tulisan pendek ini mencoba untuk menganalisis dampak pandemi COVID-19 suatu negara dalam implikasi dari masyarakat dan para tenaga medis dalam suatu kebijakan social distancing atau jaga jarak.
Microhabitat selection by overwintering alder bark beetles (Coleoptera: Curculionidae: Scolytinae) on red alder (Betulaceae)
Authors: Wertman Debra L. , Borden John H. , Carroll Allan L. 
Published: June 2022

Abstract
The alder bark beetle, Alniphagus aspericollis (LeConte), is known to overwinter as larvae and adults in the main stems of red alder, Alnus rubra (Bongard). Observations of adult alder bark beetles in the branch and bud nodes of planted saplings during the winter led to the hypothesis that these microhabitats represent alternative overwintering sites for the beetle in mature trees. To test this hypothesis, we surveyed crown branches at three coastal British Columbia locations, sampling three trees in 2003 and 2004 and three additional trees (nine branches per tree) in 2018–2019. Adult beetles were found overwintering inside sites excavated in the branch and bud nodes throughout the crowns of mature trees. Branch type, defined by growth class, and tree affected the overall distribution and likelihood of overwintering site occupancy among the three trees sampled intensively in 2018–2019, whereas overwintering site age (old versus new (current year)) affected the frequency of site occupancy across all six trees. We suggest that overwintering in tree crowns evolved from late-summer maturation feeding in new shoots and that the majority of beetles abandon terminal shoots as temperatures fall, moving deeper into the crown to overwinter preferentially in older branch tissues that offer greater thermal protection.

The aim of this study was to determine the effects of Alligator pepper, Aframomum melegueta, seed extract on wound healing in albino rats. Four treatment groups of eight albino rats each were used for the experiment. Group 1 were given feed and water only. Group 2, 3 and 4 were exposed to a reference drug (Cicatrin), 10% and 20% of the extract respectively for 21 days. Excision wounds of 30mm were made on dorsal thoracic central region of the rats. Serum from blood collected from the dorsal aorta of sacrificed rats were analysed for oxidative stress biomarkers (TNF-α, MDA and SOD) using standard methods. The tissue samples from the wounds were collected and histhopathologically analysed under a light microscope. The decrease in wound size was measured using an electronic Vernier Calliper at intervals of two days. The values of TNF-α ranged from 87pg/ml to 136pg/ml while those of MDA ranged from 0.92 to 3.19µmol/L. The maximum and minimum values of SOD recorded were 25.15U/mg protein and 12.6U/mg protein respectively. The smallest wound size value, 5.5mm, was measured in Group 3 on day 19 of the experiment. Behavioural changes were observed which included lethargy and anorexia. The histopathological study of the extract groups showed the formation of new tissues, keratinized substances and hair follicle. The results obtained from the wound measurements supported the conclusion that the extract had a better effect on the wound healing in experimental animals.

Anti-corruption law – a branch of Russian law and an academic discipline
Authors: Силкин В.П. 
Published: June 2022

В статье анализируется вопрос, является ли антикоррупционное право самостоятельной отраслью российского права. Отмечается, что в соответствии с антикоррупционной политикой государства и с учетом активного нормотворчества в данной сфере во многих отечественных высших учебных заведениях преподаются учебные дисциплины, направленные на изучение в том или ином аспекте антикоррупционного законодательства и правоприменительной практики, однако единство по данным вопросам отсутствует. Анализируются основания для выделения отраслей российского права. Приводятся доводы о том, что признание существования антикоррупционного права в качестве самостоятельной отрасли может способствовать решению многих проблем, возникающих в процессе антикоррупционного нормотворчества, повышению качества антикоррупционного просвещения и популяризации в обществе антикоррупционных стандартов. На основании проведенного исследования сделан вывод о том, что антикоррупционное право – это самостоятельная комплексная отрасль российского права, регулирующая общественные отношения, возникающие в сфере противодействия коррупции
The article analyzes the question of whether anti-corruption law is an independent branch of Russian law. It is noted that in accordance with the anticorruption policy of the state and with regard to active rule-making in this area, many domestic higher educational institutions conduct academic disciplines aimed at studying anti-corruption legislation and law enforcement practice in one aspect or another, but there is no unity on these issues. The reasons for singling out branches of Russian law are analyzed. It is proved that recognition of the existence of anticorruption law as an independent branch of law can contribute to solving many problems arising in the process of anti-corruption rule-making, improving the quality of anti-corruption education and popularization of anti-corruption standards in society. Based on the conducted research, it is concluded that anti-corruption law is an independent complex branch of Russian law regulating public relations arising on anti-corruption issues
The binding mode of pyrazolone derived copper(II), cobalt(II), nickel(II) and zinc(II) Schiff base coordination compounds with Calf-Thymus DNA
Authors: Paulpandiyan R  , Raman N  
Published: June 2022

Transition metal complexes with Schiff base ligands possess remarkable biomedical activities that could be used to develop new metal-based anticancer agents. Anticancer metal complexes have attracted considerable interest since the successful application of platinum based anti-cancer drugs. Pyrazolone derivatives have been extensively studied and have shown a wide range of pharmacological activities and anticancer activities. A new class of mononuclear copper (II), cobalt(II), nickel(II) and zinc(II) complexes were synthesized using pyrazolone precursor Schiff base, obtained by the condensation of 4–aminoantipyrine with salicylaldehyde and respective metal(II) chloride. They have been characterized by elemental analysis, magnetic susceptibility, molar conductance measurements, UV-Vis., FT-IR, 1H NMR spectra and EPR studies. Their magnetic susceptibility values of the complexes at room temperature are consistent with octahedral geometry around the central metal ions. These complexes show lower conductance values, supporting their non-electrolytic nature. The data show that the complexes have composition of [ML2] type. In vitro DNA binding profiles of all complexes have been explored by absorption titrations, cyclic voltammetry technique and viscosity measurements. The corroborative results of above experiments suggest that these complexes are efficient metallo intercalators and can interact with CT-DNA. The binding constant values (Kb) clearly signify that the complexes bind to DNA through intercalation mode. The binding affinity of these complexes with CT DNA is found to be in the order, Cu(II)>Zn(II)>Co(II)>Ni(II), among them copper complex displaying a higher binding propensity as compared to other complexes.

•	Shear on beam is defined as the internal shear stress of a beam caused by the shear force applied to the beam.
•	The fiber reinforced polymer (FRP) has arisen as a promising material for shear strengthening of RCC structures due to their superior qualities such as high specific strength, better fatigue and chemical resistance.
•	This resistance to sliding or resistance to forces that are parallel to the beam surface, generates a shear stress within the material.
•	Basalt fiber has possessed high tensile strength, better chemical and heat resistance which is higher than that of steel fiber.
•	The study finds that the beams strengthened with and without BFRP (basalt fiber reinforced polymer) strips fails in shear for L/d ratio 2.5 and the enhancement of the shear capacity of strengthened beams ranges from 5 % to 20 %.
