Paleomagnetism of the Ordovician section of the Mishina Gora (Pskov oblast): a record of the ancient geomagnetic field and restrictions on the age of the Mishinogorsk explosive structure
No full textPaleomagnetic studies of the Ordovician rocks of the Mishina Gora explosive structure
(Gdovsky district, Pskov region) have been carried out. Based on the results of thermal
magnetic cleaning, two stable magnetization components S and P have been identified.
These components have similar unblocking temperature ranges (~200–600°C), but their
mean directions are statistically different the difference of their mean directions are statistically
significant. Refional fold test indicates the postfolding age of the component S and
prefolding age of the component P. Prefolding age of the latter is supported by the positive result of the local fold-test which has been carried out in the scale of the studied section.
Comparison of the paleomagnetic pole calculated from the S component with the Apparent
Polar Wander Path for the East European Platform definitely indicates the Late Permian-
Early Triassic age of this component, which, in combination with the available geological
observations, determines the time range of the formation of the Mishina Gora structure as
~370–250 million years ago. The ancient component of the magnetization P has the same
direction as the components, which have been identified earlier in a number of coeval sections
of the North-West of Russia, Estonia, and Scandinavia and which have been considered
to be primary. The corresponding paleomagnetic poles are widely used in Paleozoic
geodynamic and tectonic paleoreconstructions with the participation of the Baltic paleocontinent.
A positive fold test result for the P component validates the use of these poles
for paleoreconstructions. For the stratigraphic interval, which includes the upper Floian,
Dapinian, and lower 2/3 of the Darrivilian stages, a magnetostratigraphic section has been
constructed containing a single magnetozone corresponding to the reverse polarity of the
geomagnetic field. Thus, the magnetostratigraphic data do not support the hypothesis of the
existence of intervals of normal polarity within the Ordovician geomagnetic superchron of
reverse polarity (Moyero superchron).This work was supported by the Russian Science Foundation, grant No. 20-17-00198 (sampling,
analysis and interpretation of data) and the Ministry of Science and Higher Education of the Russian
Federation under contract No. 14.Y26.31.0029 within the framework of the implementation of the Decree

Ethno-territorial features of social inequality in the USA
No full textThe social fragmentation of the US population has pronounced ethno-territorial features.
Using the example of ten ethnic groups of Americans of various ancestry (German, Italian,
Polish, Russian, Chinese, Asian Indian, Filipino, Mexican, Cuban, Salvadoran), the spatial features
of social inequality are examined. Six indicators of social well-being were considered in
three areas: education, employment status and earnings. The indicators under consideration
include: 1) proportion of individuals without a high school diploma; 2) proportion of individuals
with a bachelor’s degree or higher; 3) proportion of individuals who are not in the labor
force; 4) unemployment rate; 5) median annual earnings; and 6) proportion of individuals
with income below poverty level. The states and the District of Columbia were taken as the
spatial unit for analyzing the ethno-territorial heterogeneity of social inequality in the United
States. The study revealed the socio-spatial heterogeneity of the US territory, determined the
hierarchy of ethnic groups in terms of social well-being, and identified states that have the
highest deviations from the “normal” distribution of the indicators under consideration. The
results obtained make it possible to judge both the influence of ethnic origin and a specific
territory on the level of social well-being of the US population. The existing social hierarchy
of the considered ethnic groups is highly stable in most states. More often than not, members
of a particular ethnic group living in more socially wealthy states will outperform members
of the same group living in less socially wealthy states in terms of social well-being. However,
this feature is not typical for all states and ethnic groups equally. This allows us to assert that in
the United States, inequality between ethnic groups can acquire its own specific characteristics
depending on a particular territory
India: Focus Africa?
No full textThe article touches upon India’s policy towards Africa. Since the Roman era Africa has always
caught the attention of developed countries, as the continent was an enormous field for
exploring, a complete terra incognita. Later a new wave of interest came as Africa possessed
abundant resources and had connections to commercial maritime routes: the Red Sea, the
Persian Gulf, the Indian Ocean, the Atlantic Ocean. Today India does its best not only to become
a trusted trade and political partner for African states, but also to win their sympathies.
For example, Indian leaders never tire of reminding that India — just like Africa — fought
against colonialism, thereby opposing itself to the former colonial empires and emphasizing
its common historical and cultural background with Africa. The author reviews Indian
foreign policy, diaspora influence, and Indian military presence on the continent. Meanwhile
some countries, for example the U.S. or Japan, remain wary of Chinese wide-spreading influence,
especially in Africa, where a new Chinese military base was recently built. In that regard
new alliances are forming, the balance of power is shifting. A comparative analysis of Indian,
Chinese, and U.S. policy towards Africa was carried out, considering the prospects of international
relations between Africa and its key partners

Project of Revalorization and Extension of the Historic Monastery Complex of St Sigismund’s Parish in Częstochowa (Poland) — A Case Study
Get PDFThis article presents theoretical problems related to the renovation of historic buildings in
Europe of the second half of the 20th and the beginning of the 21st century. They concern the
creation of scientifically justified concepts and methods of renovation aimed at preserving the
authenticity and historical significance of monuments. Historical architectural developments,
including buildings from different eras, determine the individual appearance of historic European
cities. Architectural monuments allow one to become aware of the originality of culture
and character traits of each nation. Therefore, in the context of globalization, the study, protection
and use of historical objects is one of the factors shaping the national self-awareness.
Practical activities related to the adaptation of historical cultural space to contemporary needs
were discussed on the example of the revalorization of a 15th-century religious complex located
in the historic area of the city of Częstochowa in Poland. This area, called the “Old Town”,
is one of the main elements of the compositional canvas of the town’s urban layout (beginning
of the 19th century). The revalorization of the St Sigismund church complex together with the
monastery buildings, due to the importance for the urban layout of the city, as well as due to its
historical, cultural and religious significance, constituted an essential challenge for designers,
archaeologists, historians and local authorities
Saved art: Simferopol Art Gallery in evacuation (1941–1944)
No full textThe article is devoted to the evacuation of Crimean museum collections in October, 1941. The
fate of the lost pre-war collection of the Simferopol Art Gallery, which did not have time to leave
the Crimea and was destroyed by fire in Kerch port, is well known. At the same time, a temporary
exhibition made up of the works of the Simferopol Gallery was evacuated from Feodosiya
Art Gallery along with the masterpieces of the great marine painter Ivan Aivazovsky. Prominent
museum figures Nikolay S. Barsamov and Jan P. Birzgal managed to send the exhibits to Novorossiysk,
then to Krasnodar. Contrary to the plans of the Committee for the Arts to take these
exhibits to Stalingrad, both Crimean galleries were sent to Yerevan. At the end of 1941, Birzgal
compiled a list of 50 salvaged exhibits of the Simferopol Art Gallery. Soviet art of the 1920s–
1930s is represented by the works of Igor E. Grabar, Mitrofan B. Grekov, Vladimir A. Eyfert, Peter
P. Konchalovsky. The Russian landscape is represented by Vasiliy V. Baksheev, Pavel A. Radimov,
Vasiliy V. Rozhdestvensky. From creative trips to Central Asia, Altai and Pamir, new works are
brought by Peter I. Kotov and Peter N. Staronosov, Nikolay G. Kotov, Peter D. Pokarzhevsky, Sergei
I. Pichugin. The work of Barsamov, the author of the portrait of the artist Bogaevsky (1940),
is connected with Crimea. Among the rescued works are the works of Konstantin F. Bogaevsky
himself, several of his industrial landscapes, and sketches for the panel Crimea (1921); Bakhchisarai
landscapes by Alexander V. Kuprin, Sudak view by Alexander F. Gaush. In the postwar
period, the museum workers established the affiliation of works by Ilya E. Repin, Joseph
I. Oleshkevich, and Henri-Francois Riesener to the pre-war collection
The role of Russо-Byzantine antiquities collectors in the formation of museum collections at the turn of the 19th–20th centuries
No full textIn the context of Russо-Byzantine minor arts, hoards of the Kievan Rus’ era represent a
unique group of material culture artifacts, which are being thoroughly examined by academic
science — archaeology and art history. The history of museum affairs have accumulated
a number of studies on individual private collections, where the hoards were presented
to some extent. However, there is a demand for a comprehensive coverage of the entire
complex of hoards as the result of a “collecting fever” in the Russian Empire at the turn
of the 19th–20th centuries. The culture of this period, addressed to the styles of past eras,
made objets d’art of Byzantium, Ancient Russia and neighboring cultures to be desirable
items of collecting, which contributed to the activation of the antiquities market. When the
antiquities used to be implemented into the private collectors’ milieu, certain tendencies
of their existence in this milieu inevitably arose. This article makes an attempt to highlight beneficial and negative aspects of such tendencies, especially for humanitarian science and
museum work. Among the personalities, such as A. S. and P. S. Uvarovs, D. Ya. Samokvasov,
B. I. and V. N. Khanenko, V. V. Tarnovsky, A. A. Bobrinsky, A. V. Zvenigorodsky, M P. Botkin,
J. P. Morgan — two groups are distinguished according to their motivations and approaches:
professional archaeologists and connoisseurs of antiquities. Characteristics of structure and
acquisitions of their collections in the context of archaeological excavations are given; their
further history of existence and the role in the museumification of decorative and applied
arts monuments are revealed. A number of problematic aspects of the collectors and antique
dealers’ activity is named, such as the growth of the forgery market, the fragmentation of
monuments, which used to be single complexes, as well as the issue of national values restitution
Reflections on the Hesychian lemma βουρικυπάρισσος
Get PDFThe Greek grammarian and lexicographer, Hesychius of Alexandria (5th–6th c. CE) included
a Pamphylian gloss: βουρικυπάρισσος ἡ ἄμπελος. Περγαῖοι in his dictionary of rare and dialectal
words. Based on a microphilological and lexical analysis, I suggest that the Greek text
should be read as follows: βουρίꞏ κυπάρισσος ἢ ἄμπελος. Περγαῖοι (“bourí: cypress or grapevine.
Citizens of Perge”). The Pamphylian gloss in question represents two different borrowings
of terms originating in the Near East. The first item βουρίꞏ κυπάρισσος (‘cypress’) seems
to have been borrowed from Akkadian burāšu(m) ‘a kind of conifer tree; juniper or cypress’
with a Lycian intermediary (Akk. burāšu → Luw. *burašiš > Lyc. *burehi > *burhi → Pamph.
βουρί), whereas the second one βουρίꞏ […] ἄμπελος (‘grapevine’) reflects a separate loanword
from an Anatolian source, cf. Hitt. and Luw. muriš c. ‘a grapevine, a vine, a cluster or bunch
of grapes or other fruit’. The Pamphylian dialect of Ancient Greek represents an extraordinary
idiom, which was used in the neighbourhood of numerous Anatolian languages such as Lycian,
Milyan, Sidetic, Pisidian and Cilician. It is therefore not surprising that the Pamphylian
Greeks borrowed a number of cultural terms for plants from an Anatolian Indo-European
source, as well as from Akkadian or other West Semitic languages via Luwian and Lycian. Additionally,
other possible Anatolian borrowings into Ancient Greek (e. g. Gk. dial. βωληνή ‘a
type of grapevine’, μῶλαξ ‘id.’ vs. Hittite maḫlaš c. ‘grapevine, Vitis vinifera L.’) are mentioned
and reviewed
Dynamics of weight loss of dolomite dropouts at different stages of dissolution in Albic Retisol
Get PDFIn a laboratory experiment in 2020, the dynamics of the decrease in mass of
large particles of dolomite dropouts in acidic Albic Retisol was established. Dolomite
dropouts were collected from the landfill of a road construction factory.
The results of the laboratory experiment showed that after 114 days of composting,
the loss of dolomite mass ranged from 8.7 to 34.2 % of its initial content.
The loss of mass of particles during composting from 114 to 224 days
slowed down and fluctuated, depending on the variant, from 2.2 to 5.1 % of the
initial mass of dolomite. The mechanism of weathering was considered and the
factors enhancing the rate of dissolution of dolomite dropouts in the soil were
revealed. Linear empirical dependencies of the rate of dissolution of dolomite
in soil at different stages of the experiment were developed. Clustering of the
developed models was carried out according to the absolute values of the rate
of decrease in the mass of particles in the vessels. When selecting the dose
of application of large particles of dolomite for reclamation of acidic soils and
duration of their action, it is recommended to take into account the duration of
time the dolomite spent in the landfill.Preparation of this paper was
