Application of the algorithm for calculating the boundaries of built-up areas from satellite images to calculating the areas of flooded land and the environmental potential of the territories of settlements

The processes of flooding of the territory of settlements cause significant economic damage to the national economy. Up-to-date space information provides research on flooding over large areas. Analysis of the dynamics of flooding in the Khabarovsk Region for 2016-2019 using remote sensing methods and statistical data analysis showed that the optimal software product for processing multi-time satellite images is the MapInfo Professional GIS application. It is established that the dynamics of the areas of flooded land in settlements has similar trends, significantly differing in quantitative indicators. The most favorable year was 2017, when the least amount of land was affected by flooding. In 2019, the amount of flooded land was the maximum. 2016 and 2018 occupy an intermediate position. The proportion of flooded land was the highest in large and medium-sized cities, the lowest in rural settlements, and the small towns occupied an intermediate position due to the landscape and geographical features of the research objects. The relative decline in the value of the territory environmental potential (EFP) was also the highest in large and medium-sized cities, and the lowest in rural areas. According to the years, the increase in the temporary decline in EFP due to flooding and withdrawal from economic use of land is as follows: 2017-2016-2018-2019, which is due to the dynamics of the hydrological and climatic characteristics of these years.

MORPHOLOGY OF THE FIRST MANDIBULAR TOOTH MICROTUS GREGALIS (RODENTIA, ARVICOLINAE) FROM THE MIDDLE PLEISTOCENE OF THE PRE-ALTAI PLAIN

In this paper morphological structure of the first lower molar m1 tooth of the narrow-skulled vole from alluvial deposits of the Pre-Altai Plain Middle Neo-Pleistocene is described. Morphological study of the vole remains showed that they belong to the modern species Microtus gregalis. At the same time, the study sample showed significant differences, both in morphological structure and in the size of the first lower molar, in comparison with the recent representatives of the same territory. The set of morphological and morphometric data shows that the studied voles occupy an intermediate position between M. gregaloides of the Early and M. gregalis of the Late Neo-Pleistocene. The ratio of m1 morphotypes also showed the relative primitiveness of the M. gregalis sampling. Morphological study of remains of the narrow-skulled vole from the Solonovka, Petropavlovskoe and Malinovka-4 locations confirmed the previously determined age for sediments containing the remains of microtheriofauna.

Taxonomy of the Proisotoma complex. VI. Rediscovery of the genus Bagnallella Salmon, 1951 and epitoky in Bagnallella davidi (Barra, 2001), comb. nov. from South Africa

The genus Bagnallella Salmon is restored and given a diagnosis. It takes an intermediate position between Proisotoma Börner and Cryptopygus Willem complexes and is characterized by the separation of the two last abdominal segments (like in Proisotoma) and 3 and 5 s-chaetae on the fourth and fifth abdominal segments (like in Cryptopygus and its allies). A list of and key to species belonging to Bagnallella is given. Bagnallella bisetacomb. nov., B. dubiacomb. nov., B. sedecimoculatacomb. nov., and B. tenellacomb. nov. are commented and redescribed. Morphology of Bagnallella davidi (Barra), comb. nov. is described from the specimens from South Africa. So far B. davidi appears to be a complex of forms differing in size of the furca and macrochaetae. Two types of strongly modified males were found and described. Antennae, ventral side of abdomen, posterior edge of abdominal tergites, and mandibles are affected with epitoky. The nature of the discovered strong polymorphism is unclear.

Intergenerational leisure and family reconciliation

Scientific literature suggests the contribution to family reconciliation as a motivation for leisure shared by grandparents and grandchildren. However, there are some discrepant results. The study aimed to examine the need for family reconciliation as a practical motivation for grandparents’ and grandchildren’s shared leisure, and its linkage with its frequency, the geographical residential area, and the cohabitation of both generations in the same home. A questionnaire was administered to 357 grandparents of children aged 6 to 12 years residing in northern Spain, and a descriptive study and inferential analysis of the data were performed. The results placed the need for family reconciliation in an intermediate position, below the motivations of entertainment and emotional motivations, but above those related to co-learning and the absence of other people to perform such activities. The need for family reconciliation is associated with the frequency of shared practice, but not with the geographical residential area or the fact that both generations cohabitate at the same address. The possible exceptionality of the current situation, within the framework of COVID-19, which may have produced significant alterations in the grandparent-grandchildren relationship, is discussed, with the consequent need to continue this line of inquiry. [1] Throughout the document, an attempt will be made to use inclusive language, although "under Law 3/2007 of 22 March, for the effective equality of women and men, any reference to positions, persons, or groups included in this document in the masculine, are to be understood as including both women and men.”

Consumption and use of the main nutrients of the ration when crossbreeding cattle of Kazakh White-headed and Hereford breeds

Crossbreeding in cattle contributes to the production of crossbred young animals, which due to enriched heredity have the potential for intensive growth and achieving a high level of beef productivity. The purpose of the work was to study the infl uence of crossbreeding of cattle of Kazakh White-headed and Hereford breeds on the efficiency of consumption and use of the main nutrients of the ration by steers, heifers and castrated steers. For the experiment, 3 groups of heifers and 6 groups of steers of the following genotypes have been formed: the 1st Kazakh White-headed, the 2nd – 1/2 Hereford×1/2 Kazakh White-headed, the 3rd – 3/4 Kazakh White-headed×3/4 Hereford. At the age of 3 months half of the steers were castrated. It has been found that purebred animals were inferior to crossbreds from the crossbreeding of cattle of Kazakh White-headed and Hereford breeds. For example, during the rearing period, purebred animals of Kazakh White-headed breed consumed 2638,8– 3272,1 feed units and 2674,8–3549,2 EFU, crossbreds of the genotype 1/2 Hereford×1/2 Kazakh White–headed – 2811,6–3389,2 feed units and 2836,4–3640,1 EFU, crossbreds of the genotype 3/4 Kazakh White-headed×3/4 Hereford – 2749,2–3332,1 feed units and 2764,3–3332,0 EFU, metabolic energy, respectively, by genotypes – 26 748,1–35 492,1 MJ, 28 364,2 – 36 401,2 MJ and 27 643,1–35 941,9 MJ, digestible protein – 246,0–344,2 kg, 296,1–356,9 kg and 289,2–350,5 kg, crude protein-350,9–451,4 kg, 365,2–466,8 kg and 362,1–460,5 kg. The crossbreeding of cattle of Kazakh White-headed and Hereford breeds had a certain influence on the studied indicators. Thus, the best indicators of the efficiency of consumption and use of the main nutrients of the ration among steers, heifers and castrated steers were distinguished by half-blood crossbreds. At the same time, the largest amount of consumption of all nutrients in the ration was distinguished by steers, the smallest – heifers, castrated steers occupied an intermediate position.

Covalently Bonded Fullerene Nano-Aggregates (C60)n: Digitalizing Their Energy–Topology–Symmetry

Fullerene dimers and oligomers are attractive molecular objects with an intermediate position between the molecules and nanostructures. Due to the size, computationally assessing their structures and molecular properties is challenging, as it currently requires high-cost quantum chemical techniques. In this work, we have jointly studied energies, topological (Wiener indices and roundness), and information theoretic (information entropy) descriptors, and have obtained regularities in triad ‘energy–topology–symmetry’. We have found that the topological indices are convenient to indicating the most and least reactive atoms of the fullerene dimer structures, whereas information entropy is more suitable to evaluate odd–even effects on the symmetry of (C60)n. Quantum chemically assessed stabilities of selected C120 structures, as well as linear and zigzag (C60)n, are discussed.

Hidden in plain view: an example from Ptilidium (Ptilidiaceae, Marchantiophyta)

Ptilidium ciliare is so common in the North Holarctic and hypothetically morphologically uniform that possible diversification may have been overlooked. Previous results however showed the presence of “cryptic” diversity within the species. In the present investigation we show: 1) this diversity is not cryptic, 2) the taxon we describe as P. himalayanum has at least a Sino-Himalayan range, and 3) it occupies a morphologically intermediate position between what has traditionally been treated as P. ciliare and P. pulcherrimum. Both latter taxa are only slightly diverged genetically, and sometimes morphological discrimination is challenging such that both are better treated as varieties or subspecies within a single species.

Intervertebral disc’s features in postnatal period of ontogenesis

Aim. To reveal intervertebral disc’s morphological patterns of postnatal period. Material and methods. The morphometric study was performed on histological material obtained during 100 cases of surgical interventions on the lumbar spine for radicular syndrome. The age of the patients ranged from 19 to 77 years, median age was 45,0 (36,0; 55,0). Also, it was examined 36 samples of the intervertebral discs’ C5C6, D5D6, L5S1 anterior parts (including nucleus pulposus and annulus fibrosus) obtained in 12 cases of autopsies. The age of individuals ranged from 34 to 94 years, median age was 61,0 (50,5; 71,8) years. Staining with hematoxylin-eosin, Van Gieson method and silver impregnation was performed according to standard procedure using ready-made reagent kits. Kruskal-Wallis test and Dunn test were used for cross-group comparisons. Results. According to the morphological state of collagen fibers, all samples were divided into 4 groups. To assess the regenerative state of fibrous cartilage, a calculated coefficient reflecting the ratio of isogenic groups of chondrocytes to single chondrocytes was used. When comparing the coefficient value between the groups, statistically significant differences were obtained (p = 0,0038). The value of calculated coefficient for types I and IV-V were similar. The maximum range of values fell on type III, and type II was found in intermediate position. Statistically significant differences in the calculated coefficient between types I and III were obtained. The absence of differences in the value of the calculated coefficient between types II and III could be explained by fact that type II reflected transient state between types I and III. Type IV was found in intermediate position, as type II did. Conclusion. The intervertebral disc of postnatal period was synchondrosis. Its morphological changes didn’t depend on age and are probably related to the genetically determined strength properties of fibrous cartilage, as well as lifestyle. The proposed calculated coefficient can serve as a preliminary indicator of intervertebral disc’s biological aging stage, as well as an additional evaluation criterion in combination with color gradation based on the results of staining by Van Gieson method.

Clitic climbing

In verbal periphrases, Romance clitics either climb to the inflected verb or remain attached to the non-finite verb. The chapter argues that climbing depends on the point where auxiliaries—including restructuring predicates—are merged. Since the incorporation of clitics takes place in a clause-intermediate position (e.g. Ledgeway and Lombardi 2005), climbing does not take place when auxiliaries are first merged above the locus of incorporation. The same analysis is then extended to perfective auxiliaries in order to account for the dialects in which clitics do not climb in compound tenses and, lastly, for the dialects in which clitics never climb. The second part of the chapter focuses on the complicated system of clitic placement of Sanvalentinese, a southern Italian dialect in which optional climbing interacts with a kind of V2 requirement targeting both the I and V domain.

The Parables in Ivan Timofeev’s Temporary: Typology and Artistic Specific

The purpose of the article is to identify the specifics of the parable’s genre form in the Temporary by Ivan Timofeev. Among the full-text “parables- narrations” in the text we can distinguish parables-stories, parables-reflections, parables-instructions. The parables-stories (The Parable of the Tsar’s Roman Son ... and two parables about the widowhood of the Muscovy) are distinguished by a developed plot and represent vital examples told in order to edify and clarify the author’s attitude to historical events and persons. All parables have a two- part structure. The first part is a plot, the second is an interpretation. The technique of abstraction is appeared in the absence of a portrait and nature in many of the characters and in the absence of the historical and geographical realities. At the same time, didacticism is skillfully combined with amusement. For example, in The Parable of the Tsar’s Roman Son... the plot is entertaining with an element of the miraculous, there are elements atypical for the “classical” genre form: various kinds of the motivation for the characters’ actions, as well as a conventional portrait. The second part in the parables-stories is an interpretation that doesn’t contain a detailed disclosure of the allegory, and a prayer to the Lord, returning to the events of the Time of Troubles. An intermediate position between “parables-narrations” and “parables-maxims” is occupied by the parable of two friends. Being an example from life in content, it is close in form to apothegms. The interpretation of the plot situation is not singled out in a parable-reflection in a separate part, it is organically woven into the plot, drawing in the potential possibility of the events development. The plot of the parable about simple natural affairs reminds the instruction of how a person should act when he wants to travel to some city or another country. A laconic interpretation testifies to the fact that the parable-instruction about the completion of the path is applicable, according to Timofeev, to the creative process of writing a historical essay. In general, the parables scattered in many fragments of the text, given in full or only indicated, are a kind of companions that help not only create an extensive historical work, but also comprehend the unusual events of the Time of Troubles.
