The purpose of the work is to conduct research to determine the maximum areas affected by mud flows in the Baksan River valley (Central Caucasus). The relevance of the work lies in the fact that the objects in the Baksan River valley have repeatedly been subjected to the destructive effects of mud flows, which in different years had different parameters of the affected areas. The object of the study is the 1967 mud flows caused by an abnormal amount of precipitation. The work uses satellite images of the Corona project before and after the mud flows and Sentinel-2 satellite images reflecting the current situation. Satellite images were georeferenced in ArcMap using control points. The boundaries of the mud flow sediment zones were drawn along the characteristic light phototone during the interactive comparison of satellite images. Special attention is paid to the section of the Verkhny Baksan village, in which several houses were destroyed by mud flows that descended along the left and right tributaries of the Kyrtyk River (the Dzhugurtau and Syltransu rivers). Mudflow masses were deposited on an area of 0.22 km2 on the outflow cone of the Kyrtyk River and in the floodplain of the Baksan River, partially destroying the road on its right bank. The area of the debris deposit zone on the outflow cone of the Sagaevsky River and in the floodplain of the Baksan River was 0.18 km2. At the same time, the channel of the Baksan River was pushed to the right slope of the valley at a distance of up to 100 m. Subsequent mudflows along the Sagaevsky River did not reach the scale of 1967. It is concluded that the identified boundaries of the zones affected by mudflows of 1967 can be considered maximum and they must be taken into account when designing objects and protective structures.

At the present stage, the most important environmental issues include the problem of preserving biological diversity, which is especially relevant for natural landscapes located in urbanized conditions. In the forest areas under the conditions of anthropogenic impacts, the transformation of the regional flora takes place, thereby it adapts to the action of environmental factors. The aim of the study was to analyze the taxonomic structure of the vascular plant flora of the Forest Experimental Station of the Timiryazev Agricultural Academy (Moscow). Materials on the formation of the floristic list of the Forest Experimental Station were obtained during inventories of permanent trial ones for the period from 2000 to 2022, as well as route surveys of the territory in 2019-2022. In addition, a vascular plant download from the GBIF since 2000 was used. The study showed that the current floristic list of vascular plants of the Forest Experimental Station of the Timiryazev Agricultural Academy includes 352 species belonging to 202 genera and 68 families included in five classes. The largest taxa are the families Rosaceae, Asteraceae, Poaceae, Lamiaceae, Cyperaceae, which account for 52.3% of the species. In the Forest Experimental Station, 11 species of vascular plants listed in the Red Book of Moscow were identifi ed. The fraction of adventitious vascular plants in the flora of the Forest Experimental Station includes 99 species (28.1% of the total number of identified species), belonging to 66 genera and 34 families. Among the families of the adventitious fraction, the most multispecies are Rosaceae (22 species), Aceraceae (10 species), Asteraceae (7 species), Pinaceae (7 species). The proportion of adventitious species does not exceed 30%, so the fl ora should be considered natural, slightly disturbed. Despite the high level of recreation, pollution from road transport, the plant communities of the Forest Experimental Station continue to retain signs of a natural object that correspond to the natural conditions of the Moscow region.

The aim of the study was to study the effect of the biostimulator of growth «Biostim» on the germination and development of seeds and seedlings of woody species in order to develop a resource-saving technology of cultivation for nursery breeding in the Volgograd region. The objects of research were the woody species Quercusrobur L., Robiniapseudoacacia L., PopulusbolleanaLouche., Populusnigra var. italica Münchh., Catalpa bignonioides, Pinusnigra subsp. pallasiana (Lamb.), Platycladusorientalis (L.) Franco., Piceapungens Engelm. ofdifferentgeographicalorigin. As a result of the conducted studies, the best result was shown by poplars and catalpa with a concentration of «Biostim» at a dose of 2.5 l/ha (20 ml) for cuttings and 20 ml/l for seeds. The concentration of the preparation at a dose of 10 ml / kg (the consumption of the working solution is 1.5-2 l/kg) with soaking of seeds before sowing for 10-20 minutes, followed by drying, was suitable for Robiniapseudoacacia. The concentration of the preparation in a dose of 10 ml / l with soaking of the seeds before sowing for 10-20 minutes followed by drying was suitable for robiniapseudoactation. The worst result in the test of laboratory germination of seeds was shown by oak petiolate, due to the lack of reaction of seeds to processing and their mold formation. In coniferous species, the best result was shown by Crimean pine with a concentration of the preparation«Biostim» of 10 ml / l and 2.5 l / ha. The germination of spruce and thuja seeds was weak. According to the results of the test of the preparation «Biostim» on seedlings and seeds in a nursery on dark chestnut soils, the best result was shown by seedlings of poplar and catalpa species with a concentration of «Biostim» at a dose of 2.5 l/ha and 20 ml/l for seeds. Additional top dressing with poplar preparation proved to be effective, after which good growth, development and leafing of plants were observed. Seedlings and seeds of eastern thuja and blue spruce after additional processing grew and developed satisfactorily, subsequently their drying and loss was observed, which makes the topic of testing biostimulators of growth on conifers is promising for further research.

Agriculture in the arid climate of Saratov Zavolzhye is not able to provide high yields of crops without the use of special tools to increase moisture reserves in the rootontaining layer of soil. In this regard, the development of melioration in Saratov region is a strategically important task. Sprinkling is the main way to increase the moisture supply in the soil. The modern domestic sprinkling machine «Caskade 65T» is the most suitable for the realization of this method. For safe and effective operation of «Caskade 65T»SM the following conditions should be observed: no objects on the field interfering with the passage of self-propelled carts and the machine as a whole; permissible longitudinal slope of the area up to 4…12% (depending on design and length of the sprinkler machine spans); permissible slopes in the course of machine movement up to 5…12%; difference in slopes between two adjacent spans up to 6…14%, while the total slope of the field along the sprinkler machine must not exceed 7%. It is recommended to set the direction of machine movement in such a way that its ascent to an elevation occurs along the gentlest slope.

The purpose of the research is to study the contamination of the bottom sediments of the Ivankovsky reservoir with heavy metals. These deposits of water bodies are quite sensitive indicators of their pollution. The most unfavorable pollutants are the following metals and trace elements: As, Cd, Hg, Zn, Pb, Cu, Cr, Co, Ni. According to the data of the work carried out in 2021, the trends in changes in the pollution of the bottom sediments of the Ivankovsky reservoir are considered. The content of mobile forms of existence of the following microelements was determined: Cd, Cu, Pb, Zn, Cr, Ni and As. The content of trace elements by forms of existence was determined by the method of A. Tessier, the results of the studies are given in accordance with the assessment by igeo-classes – by the contamination of the sorbent fraction (less than 0.02 mm). The main polluting elements in the mobile forms of the bottom sediments of the reservoir are cadmium and lead, for which the level of pollution is estimated within the 2nd igeo-class – from weakly to moderately polluted. A picture of both the contamination of the bottom sediments of the Ivankovsky reservoir with trace elements, and the distribution and ratio of their mobile forms of existence in the sediments is presented. Elements such as Pb, Zn and Cr are mainly in a form bound to iron and manganese hydroxides; Co, Cd, Ni, Cr and Cu are mostly in ion exchange and carbonate forms. Based on the data obtained, at present, the load on the studied objects is not dangerous. The obtained results are of scientifi c and practical interest for organizations of geo-ecological orientation, for specialists in the fi eld of environmental protection and nature management.

Published: April 2023

The authors report on the capture of a specimen of smoothback angelshark Squatina oculata Bonaparte, 1840 from Turkish marine waters. The specimen measured 720 mm in total length and
was caught by means of a commercial purse-seiner at a depth of 60 m. The species appeared to be sporadically caught in the area and the eastern Mediterranean Sea, however, the size diversity of recorded specimens shows the species still occurred in the region. Although the smoothback angel shark is listed as a protected species according to Turkish Marine Fisheries Act, a management
plan should be integrated with local fisheries to preserve the species from extirpation throughout its distribution range in Turkish seas.

Authors: Fontes Breno Augusto Souto
Published: April 2023

Este breve ensaio tem por objetivo resgatar parte das agendas de pesquisa bastante diversas, orientadas a partir das trajetórias temáticas “redes sociais” e “sociabilidade”. Essas trajetórias ilustram de forma bastante clara a importância deste recorte teórico-metodológico para a investigação de uma ampla gama de questões das ciências sociais contemporâneas. Interessa-nos, particularmente, a construção das sociabilidades mediadas pela internet, a partir de plataformas de comunicação on-line, nas quais é possível o estabelecimento de interações sociais com múltiplos atores, recuperando salas de conversa, espaços de convivialidade antes experimentados nas interações face a face. São, como vemos nas abordagens que se destacam por sua atualidade e porquanto construídas a partir da Sociologia das redes sociais, originais.  É um exemplo importante do desenvolvimento dessa, cada vez mais relevante, agenda de pesquisa: a abordagem dos comportamentos humanos a partir da constituição da sua estrutura reticular, mas ancorada a partir da mediação da tecnologia do espaço virtual.
Do organograma ao rizoma

Published: April 2023

As plataformas digitais, em especial os aplicativos de mensagens como WhatsApp e Telegram, assim como as dinâmicas de comunicação em rede impactam o modo como o conhecimento é compartilhado em organizações e empresas. Nesses ambientes, os fluxos de conhecimento seguem uma nova lógica organizacional, menos hierárquica, de maneira espontânea, não seguindo orientações top-down. Este artigo tem como objetivo refletir sobre os impactos dessas novas dinâmicas na gestão do conhecimento a partir do conceito deleuziano-guattariano de rizoma. Trata-se de um estudo exploratório que utiliza como metodologia a revisão de literatura sobre os conceitos de gestão de conhecimento e rizoma, assim como algumas possíveis articulações entre eles. A partir dessa revisão foi realizada a análise do compartilhamento organizacional pela abordagem de três princípios do rizoma deleuziano-guattariano (conexão, heterogeneidade e multiplicidade) e das potenciais implicações dessa abordagem na gestão do conhecimento organizacional. Espera-se, assim, contribuir com as discussões teóricas sobre compartilhamento de conhecimento em rede e sua gestão no âmbito organizacional. Para além de pensar algumas possíveis modulações nas práticas de gestão de conhecimento, foram apontadas outras questões desdobramentos em outros estudos que, pela relevância, devem ser mantidas como marcos a serem observados, como movimentos futuros de outros estudos.

Kombucha is produced by the action of sugar and fermentative symbiotic colonies of bacteria and yeast (SCOBY) in black and green tea infusions. The main active substances in kombucha are polyphenol compounds (epigallocatechin gallate, epicatechin gallate, gallocatechin gallate, epicatechin, epigallocatechin, gallocatechin, and catechin), vitamins (B1, B2, B6, B12, and C), and organic acids (D-gluconic acid, and glucuronic acid). Several studies have reported that the main health benefits of kombucha include its energizing and detoxifying properties, in addition to anticancer and anti-aging effects. Sugar is a very important component necessary for glucose fermentation. However, this may result in increased consumption of calories depending on the sugar content. Therefore, this study investigated the quality characteristics of commercial kombucha and manufactured low-calorie kombucha (MLK) using alternative sweeteners (non-digestible maltodextrin, enzymatically modified stevia, or sucralose) and different levels of sugarcane content. The total soluble solids content, pH, color, organic acids, catechins, and caffeine content in kombucha during fermentation were then measured. The results showed that there was no significant difference in color. However, the pH of the MLK decreased from 5.4 to 2.81 during fermentation. Interestingly, the highest D-gluconic acid content was observed when 5% (w/v) sugarcane was added to the MLK and fermented for 16 days. The catechin contents did not change during fermentation. The caffeine content decreased from 2.00 ± 0.01 mg/100 mL to 0.94 ± 0.00 mg/100 mL. In conclusion, this study developed low-calorie kombucha using alternative sweeteners, which suggests a new trend in the manufacture of kombucha.

Percepção ambiental pode ser definida como sendo uma tomada de consciência do ambiente pelo homem, ou seja, o ato de perceber o ambiente que se está inserido, aprendendo a proteger e a cuidar do mesmo. Sendo que cada indivíduo percebe, reage e responde diferentemente às ações sobre o ambiente em que vive. Desta forma, o estudo da percepção ambiental é de fundamental importância para que possamos compreender melhor as inter-relações entre o homem e o ambiente, suas expectativas, anseios, satisfações e insatisfações, julgamentos e condutas. O objetivo desse trabalho foi avaliar a percepção dos moradores da comunidade Pará Batins sobre o uso do nim-indiano na arborização local, para a coleta de dados foi utilizada duas metodologias a aplicação de questionários para os alunos da escola estadual e entrevista estruturada para os moradores. Os resultados mostraram que 56% dos moradores e 80% dos alunos conheciam a planta nim que fator positivo, mas 76% moradores e 52% dos alunos não tinham conhecimento do que seria arborização o que são dados preocupantes, sendo que 72% dos moradores e alunos veem vantagens na mesma e citou a sombra como principal função, em relação a desvantagens 36% dos moradores e 80% alunos viram desvantagens, e citaram as sujeiras nas calçadas sendo a principal. Já 36% dos moradores e apenas 4% dos alunos responsabilizam a prefeitura pelo plantio de árvore na comunidade, o que é um fator negativo devido ser números muitos baixos, e 96% dos moradores e 80% dos alunos não cortariam a planta de fronte de suas casas para ficar sem nenhuma, comprovando que os entrevistados reconhecem sua importância para a comunidade.

Understanding relativistic time: Exploring the concepts of spacetime and time dilation
Authors: Lingefjärd Thomas
Published: April 2023

Relativistic time deals with concepts as spacetime and time dilation. I will try to explain this as clearly as possible. To explain the concept of spacetime is not at all impossible, although it is four-dimensional. But that means that we define it using four numbers. If we describe us through age, weight, height, and IQ, that would be a four-dimensional representation of us.
Slurry erosion wear of high chromium cast iron samples from a slurry pump impeller. Effect of impact angle variation
Authors: Chaves Pereira da Silva, Renato  , Barbosa, Paulo Ricardo  , Penagos, José Jimmy  , Rodrigues da Costa Adilson
Published: April 2023

In this work, the impact angle effect on the erosive wear resistance of high chromium cast iron (HCCI) samples from a slurry pump impeller was evaluated. For this purpose, equipment was designed and built to carry out wet erosion tests. Erosion tests were carried out at angles of 30°, 45°, 60° and 90° using an erosive slurry with a concentration of 20%, by weight, of silica sand. The results indicated that the erosive wear rate followed the classic behavior of variation with the impact angle for ductile materials. There was an increase in the erosion rate with increasing angle until reaching the peak wear at 45°, followed by a decrease in wear down to the minimum wear rate at 90°. Significant differences were observed in the mass loss of the HCCI samples: the samples eroded at 45° showed a mass loss 2.7 times greater than the eroded condition at 90°, indicating that, due to the condition of slurry contact with the surface of the samples, erosive and abrasive mechanisms acted synergistically favoring wear at 45°. On the other hand, samples eroded at 30° and 60° showed similar and intermediate mass losses. In general, for the samples eroded at a normal angle (90°) the mechanisms of wear due to plastic deformation of the matrix and carbide fracture were observed, while for smaller angles, the mechanisms of micro cutting and micro grooving were more evident.

Published: April 2023

In Indonesia, around 9.89 million tons of Fly Ash and Bottom Ash (FABA)waste is generated annually from burning coal in steam power plants (PLTU). One type of FABA waste categorized as Non-B3 which isBottom Ash with a waste code of N107.Ifthis waste not utilized,itwill only become a waste product. With theIndonesia Government Regulation No. 22 of 2021, this waste utilization process becomes more manageable and has the opportunity to be optimized. One of the recommended alternative uses of Non-B3 FABA is substituting raw materials for infrastructure materials, especially for coastal areas where it is difficult to obtain fine aggregate.In the process of development, coastal areas are often in contact with sea air.Seawater has a high salt content which can undermine the strength and durability of concrete, so this study focuses on discussing the effect of using Bottom Ash as a fine aggregatesubstitute on concrete strengthofthe M24concrete, which is influenced by the sea's tides. By using the ACI 211.1-91 concrete mix design method, experimental concrete samples were made by substituting fine aggregatewith bottom ash N107 with a percentage of 0%,20%and 30% and a maximum coarse aggregate size of 20 mm, the treatment of concrete samples was carried out in freshwaterand in the tidal zone. From the sample of concrete with 20% and 30% bottom ash, it is known that the porosity of the concrete immersed in the tidal zone is higher than that of the concrete immersed in fresh water. For concrete that was given maintenance treatment in the tidal zone, the compressive strength decreased at 56 days.

Published: April 2023

The objective is to study the possibility of ob-taining titanium silicide using the azide technology of self-propagating high-temperature synthesis (SHS-Az) in silicon-titanium halide-sodium azide system.

The task to which the paper is devoted is to find the optimal composition of the charge, which combus-tion gives the opportunity to obtain titanium halide by SHS-Az method.

Research methods: the study of the titanium sil-icide synthesis in powder is carried out in the mode of solid-flame combustion in SHS-Az laboratory reactor. The synthesized powders are subjected to studies al-lowing to define the phase composition and structure. The studies are carried out using a diffractometer and a scanning electron microscope.

The novelty of the work is in synthesizing tita-nium silicide not only by a new method in the mode of high-temperature combustion of the heterogeneous silicon-titanium halide-sodium azide system, but also by obtaining a powder with close values to the range of nanoparticles.

Study results of obtaining titanium silicide by SHS-Az method from the heterogeneous silicon-titanium halide-sodium azide system show that the target product is a finely dispersed mixture of particles of equal shape but of different phase composition: Ti5Si3, TiSi2, TiN, Si, Ti. The average particle size is equal to 150-200 nm.

Conclusions: it is found that Ti5Si3 and TiSi2 ti-tanium silicides can be obtained in the combustion mode by SHS-Az method from silicon-titanium halide-sodium azide system.

Authors: Skachkov Aleksandr , Trifonov Valery , Samoshkin Sergey
Published: April 2023

The issues of increasing the passenger comfort level during railway transportation are considered. It is found out that the key factors for the comfort level are vertical vibrations of the body, and their intensity directly depends on the body bending stiffness. In turn, the first frequency and form of bending vibrations of the body can be taken as a criterion for evaluating bending stiffness. Design concepts aimed at increasing the comfort level of passengers and reducing the intensity of vibrations of car bodies are considered. Methods are analyzed that give the opportunity to increase the intrinsic frequency of the body bending vibrations by strengthening the metal structure of the body and making changes to the structure of its power frame, as well as by introducing specific inter-car connections. Methods of vibration isolation of the car bodies are reviewed by controlling damping in the car suspension system, as well as by reducing vibrations associated with the imbalance of wheel pairs. The experience of increasing the level of the com-fort due to the introduction of additional damping and the use of dynamic vibration damping systems has been studied. Advantages and disadvantages of the considered technical solutions are identified, as well as the experience of their use in real operation is evaluated. The analysis of the problem under consideration concerning engineering solutions for reducing bending vibrations of passenger car bodies shows the complexity of solving this problem, requiring the use of a set of theoretical and experimental studies, the choice of methods that take into account the features of the car designs and sources of vibration stimulation.
