The novel pushing gravity model and volcanic activity. Is alignment of planets with compact stars a possible cause of natural phenomena?
Authors: Greco F , Krasnyy I V 
Published: November 2021

Abstract
We developed the model, and carried out its discussion at the PIRT-2021 conference, within the framework of the research topic “External Forcing on Volcanoes and Volcanic Processes: Observations, Analysis and Implications” announced by the journal “Frontiers in Earth Science” in October 2020. Besides other, external processes considered in this Research Topic included astronomical. In this study, in the category “Hypothesis and Theory”, we investigate how changes in the position of large bodies of the Solar system can cause natural phenomena, associated with the movement of free masses, such as volcanism, earthquakes and landslides in the lithosphere, as well as various catastrophic events in the atmosphere and hydrosphere. The analysis has shown that the discovered phenomena of celestial bodies’ alignments accompanying manifestations of natural phenomena require going beyond the standard cosmological model and clarify the fundamental mechanism of gravity. We propose the novel Bidirectional Pushing Gravitation model (BPG), which, in addition to application in Earth Sciences, may occur useful in Astrophysics, Cosmology and Gravitation research.
Geometry and kinematics induced by biquaternionic and twistor structures
Authors: Kassandrov V V , Markova N V 
Published: November 2021

Abstract
The algebra of biquaternions possess a manifestly Lorentz invariant form and induces an extended space-time geometry. We consider the links between this complex pre-geometry and real geometry of the Minkowski space-time. Twistor structures naturally arise in the framework of biquaternionic analysis. Both together, algebraic and twistor structures impose rigid restriction on the transport of singular points of biquaternion-valued fields identified with particle-like formations.
Examples of Calabi-Yau threefolds with small Hodge numbers
Authors: Shishanin A O 
Published: November 2021

Abstract
We observe some suitable examples of Calabi-Yau threefolds for heterotic superstring compactifications. It is reasonable to seek CY threefolds with Euler characteristic equals ±6 because of generation’s number. Hosotani mechanism for violations of the gauge group by the Wilson loops requires such CY space has a non-trivial fundamental group. These spaces can be obtained by factoring the complete intersection Calabi-Yau spaces by the free action of some discrete group. Also we shortly discuss cases when discrete groups act with fixed point sets.

Abstract
Due to the strategies implemented to carry out the development of a correct teaching by virtual means, a methodological strategy of experimental tests was developed for the identification of polymeric materials through the identification of physical and chemical properties, with the objective of providing the engineering student a greater approach to the application of the scientific method and the activation of the capacity of reasoning and deductive thinking from the physical and chemical point of view. Therefore, the purpose of this research was to validate this strategy implemented with a group of engineering students, for this purpose, the strategy was implemented, and the results obtained by the students from the development of the experimentation were analyzed, the data were analyzed by means of nonparametric tests, in this case binomial test. Finally, it is concluded that the polymer identification test is feasible to be implemented as a remote laboratory, as a methodical strategy in teaching, since it allows the development of experimentation, in this case, the identification of polymeric materials, which present diverse physical properties.
Diffuse scattering and physical optics in the propagation of electromagnetic waves applied to mobile communications
Authors: Gomez-Rojas J , Medina-Delgado B , Palacios-Alvarado W 
Published: November 2021

Abstract
In this work, the optical theory of physics helps to understand, analyze, and calculate the received power in a fifth-generation mobile telecommunications receiver. In these communication systems there are statistical models and deterministic physical models. We investigated how diffuse scattering in reflection contributes to specular reflection in received power at a receiver due to materials in the propagating environment in a communication channel using millimeter waves. The dimensions of building construction materials have sizes comparable to wavelength at millimeter wave frequencies. The power transmitted by communication equipment can be reflected in the roughness of these apparently smooth materials or spread out in multiple directions. The results show that the contribution due to diffuse scattering must be considered and that deterministic physical models using optical theory are valid and improve predictive analysis with good fit. With these results, the physical theory allows to make software with high precision and that improves the current applications.
Search for relativistic magnetic monopoles with ten years of the ANTARES detector data
Authors: Boumaaza J. , Brunner J. , Moussa A. , Tayalati Y. 
Published: November 2021

Abstract
The presented study is an updated search for Magnetic Monopoles (MMs) using data taken with the ANTARES neutrino telescope over a period of 10 years (January 2008 to December 2017). In accordance with some Grand Unification Theories (GUT), MMs were created during the phase of symmetry breaking in the early Universe, and accelerated by inter-galactic magnetic fields. As a consequence of their high energy, they could cross the Earth and emit a significant signal in a Cherenkov-based telescope like ANTARES, for appropriate mass and velocity ranges. This analysis a new simulation of MMs taking into account the Kasama, Yang and Goldhaber (KYG) model for their cross section with matter. The results obtained for relativistic magnetic monopoles with β = v/c ⩾ 0.817, where v is the magnetic monopole velocity and c the speed of light in vacuum, are presented.

Published: November 2021

Abstract
This paper presents the first determination of the spatial
resolution of the ANET Compact Neutron Collimator, obtained with a
measuring campaign at the LENA Mark-II TRIGA reactor in Pavia. This
novel collimator consists of a sequence of collimating and absorbing
channels organised in a chessboard-like geometry. It has a scalable
structure both in length and in the field of view. It is
characterized by an elevated collimation power within a limited
length. Its scalability and compactness are added values with
respect to traditional collimating system. The prototype tested in
this article is composed of 4 concatenated stages, each 100 mm
long, with a channel width of 2.5 mm, delivering a nominal L/D
factor of 160. This measuring campaign illustrates the use of the
ANET collimator and its potential application in neutron imaging for
facilities with small or medium size neutron sources.
Storm surge risk under various strengths and translation speeds of landfalling tropical cyclones
Authors: Xuan Jiliang , Ding Ruibin , Zhou Feng 
Published: November 2021

Abstract
Landfalling tropical cyclones (TCs) frequently occur with strong intensity in most coastal areas, and storm surges are likely to occur in response to extreme sea level (ESL) growth. However, the level of ESL growth under various wind conditions, coastline geometries and tide-surge interactions has not been clarified. In the Pearl River Estuary and Daya Bay, observations of landfalling TCs have indicated an increasing frequency of intense and rapid landfalls in the 2010s as compared to the 2000s, accompanied by a noteworthy increase in storm surge. Based on a large ensemble (∼0.5 million storm surge events with various tracks, maximum wind speeds, maximum wind radiuses, translation speeds and tidal conditions) obtained from well-validated model simulations, the ESL growth in the study area is further quantified as follows: (a) ESL growth is more sensitive to the acceleration effect of landfalling TCs than to the strengthening effect of landfalling TCs since the effect of low acceleration (+3 m s−1) is comparable to that under notable strengthening (+10 m s−1); (b) ESL growth is strongly modulated by coastline geometry, especially in flared or arching coastline areas. ESL growth mainly occurs along flared coastline areas when landfalling TCs strengthen into severe TCs or typhoons but can also occur along arching coastline areas for stronger landfalling TCs, such as severe typhoons or supertyphoons; and (c) ESL growth could be increased or decreased by approximately 10% under the effect of tide-surge interactions. Both the large-ensemble method and the above ESL growth characteristics are worthy of attention in risk assessment and rapid prediction of storm surges in shallow waters.
Weakened dust activity over China and Mongolia from 2001 to 2020 associated with climate change and land-use management

Published: November 2021

Abstract
Dust cycle is actively involved in the Earth’s climate and environmental systems. However, the spatiotemporal pattern and recent trend of dust emission from the drylands in East Asia remain unclear. By calculating dust aerosol optical depth (DOD) from the newly released moderate resolution imaging spectrometer aerosol products, we obtain a relatively long satellite-based time series of dust activity from 2001 to 2020 over China and Mongolia. We identify pronounced interannual variability of dust activity that is consistent with ground-based meteorological observations in the study area. A substantial reduction in spring dust activity in northern China is also found, which seems in accordance with the long-term weakening trend since the 1970s that has been attributed to the wind speed decline by previous studies. However, the spatial pattern of the trends in both annual mean and seasonal dust activity during the last 20 years is divergent, and the most significant dust diminishing is found over north-central China where large-scale vegetation restoration projects have been implemented. It indicates that in addition to the potential contribution of wind speed change, land-use change also plays an important role in the recent inhibition of dust emission. The current results show that dust activity occurs most intensively in spring, followed by summer and relatively weaker in autumn and winter. However, dust activity in autumn and winter has increased significantly in NW China despite the overall decreasing trend in other two seasons, probably associated with different seasonal atmospheric and land surface conditions. Finally, the DOD distribution reveals that the Tarim Basin, Gobi and Qaidam Basin Deserts are three major dust sources in East Asia. Compared to ground observations which are spatially limited and distributed unevenly, remote sensing provides an important complement, and it can serve as reference for identification of dust sources using other methods such as geochemical fingerprint and modeling.
Public support for climate adaptation aid and migrants: a conjoint experiment in Japan
Authors: Uji Azusa , Song Jaehyun , Dolšak Nives , Prakash Aseem 
Published: November 2021

AbstractWe examine public support in Japan for overseas climate adaptation assistance via foreign aid and accepting immigrants. Using a survey-embedded conjoint experiment (N= 2815), we focus on seven attributes of an adaptation policy package: (a) the continent in which the country is located; (b) the types of extreme weather event this country faces; (c) the volume of climate aid; (d) the number of climate migrants (e) Japanese exports; (f) Japanese imports, (g) the country’s record of voting with Japan in the United Nations. We find that while respondents are indifferent to aid volume, their support diminishes as the number of migrants increases. Moreover, support is higher for Asian countries, that provide export markets, vote with Japan, and where the effects of climate change are gradual. Importantly, we find that public support is not influenced by benchmarking of Japan’s or peer G7 countries’ past aid or immigration levels.

Interspecific agonistic behaviour of Odontotermes javanicus and Microcerotermes sp. (Isoptera: Termitidae): Preliminary study
Authors: Arif A , Muin M , Putri G , Hasil N 
Published: November 2021

Abstract
Termite interaction from the same or different colonies or species can display a variety of agonistic behaviours. The study aimed to observe the interspecific agonistic behaviour of Odontotermes javanicus and Microcerotermes sp. For this purpose, an assay was carried out using a test arena separated into two groups. Termite responses were tested against each other in the following pairwise test (worker versus worker, worker versus soldier, and soldier versus soldier) with a 1:1 ratio (ten individuals) from each colony. Specimens were collected at the area of Forestry Faculty, Universitas Hasanuddin, Indonesia. The observed agonistic behaviour of both species is dominated by examination (antennation) and aggression (attacking, grappling, and biting). There were three treatment combinations that classified as no aggression, except for the treatment (Microcerotermes sp. soldier versus O. javanicus worker) that classified in aggression level 3 (aggressive). Based on termite survival after five minutes of testing, O. javanicus is more competitive than Microcerotermes sp,; no more individual termites of both species survive after 24 hours of testing.

Published: November 2021

Abstract
The article explains the stages of modern environmental policy formation and analyzes decarbonalization as a component of climate change, which requires the introduction of global regulation without taking into account any national priorities and the transition to global control over national economies through the OPEC oil and gas sector. The content of greening is revealed and it is noted that global warming in the climate has shifted to stable and dynamic regional geographical cooling, which makes not only doubt the causes of global ecological warming, but also to identify political motives for decarbonization and primarily in energy. The intensified development of wind farms has been noted as a result of the global policy of developed countries that do not have sufficient own reserves of coal and oil and gas hydrocarbons.
Maintaining the economic safety of environmental activities in agriculture
Authors: Krasovska Yu , Kuznietsova T , Kostrychenko V , Lesniak O 
Published: November 2021

Abstract
This article is devoted to the study of directions to ensure a sufficient level of economic safety of farms. The multifactorial nature of threats to the external environment and internal factors determining various aspects of economic safety of agricultural enterprises is determined by their wide range and complexity of influence. The high level of risk that results from such influence, on the one hand, makes the activities of such enterprises economically vulnerable but, on the other hand, makes this business attractive. Calculations on the basis of empirical agricultural data confirm that from 40 to 60% of income (depending on location and weather conditions) they can lose from inappropriate groundwater table and not sufficient meliorative state of soils. To substantially reduce this figure and to increase the level of economic safety, it is proposed to optimise the parameters of drainage systems and achieve land reclamation improvement by constructing a water discharge justification model as a key factor for achieving necessary drainage rates. In addition, the use of crop diversification model within justified crop rotations will allow to significantly increase the level of economic safety of farms by optimizing price risks.

Abstract
The article is devoted to the issues of substantiation of a new ecological worldview built on the basic principles of environmental culture. It is shown that the violation of the means of maintaining balance in the system “a man-nature-society” poses a significant threat to the existence of a man as a biosocial being, determining the appropriate response of nature to destructive human activities, requiring the identification of environmental priorities for further socio-cultural development. It was found that solving problems related to the current environmental situation involves limiting human practical and transformational activities aimed at transforming nature into the introduction of “careful”, “gentle” consumption with the need to adjust the criteria of environmental feasibility, it is possible in the formation of environmental culture and deepening the field of environmental education. We have established that the innovative direction of the state’s development should be focused on the targeted satisfaction of the consumer needs.The main indicators of the labor market in 2013-2019 are analyzed as well as personnel costs of business entities. The closeness of the relationship between net income and labor costs of enterprises is established.

Published: November 2021

Abstract
The main idea of the study is based on the assumption that the level of representation of a term in scientific journals and articles can represent the main stages of this term formation in scientific discourse. The analysis of the representation of the term “environmental sustainability” in open access scientific journals provides an opportunity to explore the basic patterns of development the idea of environmental sustainability in certain areas of knowledge. The aim of the study is to analyze statistical data on the use of the term “environmental sustainability” in scientific journals to outline the scope of scientific content of environmental sustainability in scientific and information space. The analysis was carried out in two directions: the use of the term in certain areas of research; general presentation of the term in the scientific apparatus of articles. It is established that the leading factors of general social content, which led to the emergence of the concept of ecological sustainability in scientific texts, were global environmental problems. The dynamics of using the term over the past few decades is described and three main stages of this concept implementation in the scientific and information space are identified: fragmentary, gradual stability and dynamic.
