Indo-Roman lamps from Ter: the long shadow of Rome or the light of transculturation?
Authors: Autiero Serena 
Published: December 2020

Ter, ancient Tagara, in the Osmanabad district (Maharashtra), is among the most important sites when discussing Indo-Roman relations. Local production of small artefacts, such as pottery lamps and figurines, reveals an enthrallment for the exotic resulting in new transcultural visual solutions. The shape, iconography, and execution of terracotta lamps of the so-called Indo-Roman type from Ter are a clear witness to this phenomenon. The absence of precise comparisons with Western productions, and the impossibility to connect them to a direct trade of lamps confirm the transcultural value of these lamps. They are indeed the product of intermingling and contact, not just a copy of well-known types; they are better understood as an original product of Indian manufacturers based on a current stylistic trend gathering inputs from different media and materials. The result is a syncretic original product, created to satisfy the refined taste of urban mercantile elites. These lamps definitely show how alien visual culture found a welcoming environment in the countries involved in ancient globalisation.
Reconstruction of the bases of sandstone sphinxes from the Temple of Hatshepsut at Deir el-Bahari
Authors: Kasprzycka Katarzyna 
Published: December 2020

The reconstruction of the iconographic program of the decoration of the sandstone bases of a group of sphinxes of Hatshepsut lining the processional avenue leading to the Queen’s Mansion of a Million Years in the temple at Deir el-Bahari is the prime focus of this article. The fragments of these statues discovered in the 1920s by the archaeological mission of the Metropolitan Museum of Art in New York were never published. The pieces were rediscovered in storage in 2005. A theoretical reconstruction has been undertaken, leading the author to identify an unusual iconographical pattern that reflects changes in art introduced in the times of Hatshepsut. The representations on the bases of the royal sandstone sphinxes from the queen’s temple include, among others, rekhyt birds, pat-people and “enemies of Egypt”. They take on a form that departs from that known from other sphinx sculptures.
Makuria in the middle of the 12th century
Authors: Godlewski Włodzimierz 
Published: December 2020

In the middle of the 12th century, the King of Dotawo (Makuria) and Arwa, referred to as Mouse Georgios in many Old Nubian documents and in studies on the subject, was the eparch of Palaga, a province of the Kingdom of Arwa, and in all likelihood the official heir of King Paulos of Arwa. He was crowned King of Makuria (Dotawo) in 1155, following mediation by the Fatimid caliph between the two kings, Georgios V of Makuria and Paulos of Arwa. The crisis was triggered by David, a presumed member of the Arwa royal family, usurping the throne of Makuria. The paper marshals the evidence for a hypothetical reconstruction of the political situation in the region in 1155 and considers the reasons for King Mouse being called Mouse Georgios in Old Nubian documents from Qasr Ibrim.
Spatial–temporal distribution of heavy precipitation over Ukraine during 1979-2019 according to the ERA5 reanalysis
Authors: Semerhei-Chumachenko A. B. , Slobodianyk K. L. 
Published: December 2020

The paper presents the results of research of heavy and extreme precipitation in the form of rain (> 50 mm / 12 h) and snow (> 20 mm / 12 h) using the data from the atmospheric reanalysis ERA5 for the period of 1979-2019. According to the data of the European Centre for Medium-Range Weather Forecasts obtained through the numerical modeling and resulting from the data assimilation at the nodes of a regular grid with a spatial resolution of 0,25°×0,25°, there are 131 and 136 days with rain and snow during which precipitation intensity reached the criteria of meteorological phenomena of the 2nd and 3rd levels of danger. It was discovered that the last 40 years in Ukraine proved to have a tendency of an increased number of cases of heavy snowfall, and a slightly decreased number of heavy rains.
The research pays considerable attention to the spatial-temporal analysis of the frequency and intensity of heavy rainfall with consideration of geographical factors. It determines the seasonal course of heavy and extreme precipitation, the maximum and minimum values of which did not differ from the climatic standard values observed during meteorological observations. Rainfalls with precipitation rates of more than 50 mm over 12 hours were observed almost over the entire territory of Ukraine and the maximum frequency zones were detected over the Carpathian Mountains, Donetsk Ridge, Podolsk Upland, and the south-western part of the country. Heavy snowfalls with more than 20 mm precipitation over 12 hours mostly occurred in the Carpathian region. The analysis of the geographical distribution revealed a center with maximum values of rain intensity (120-133 mm over 12 h) off the coast of the Sea of Azov, and the heaviest snowfalls (34-38 mm over 12 h) mainly formed in the Carpathian region.
The paper established the types of elementary circulation mechanisms of Dzerdzeevsky’s synoptic classification of Northern Hemisphere atmospheric circulation. These types, when continuous in nature, resulted in a significantly increased precipitation in the form of rain and snow.
According to the reanalysis data, cases with the maximum rain intensity were found over the period of 23 to 27 July 2008 when a catastrophic flood was observed in the Ukrainian Carpathians. This fact indicates that the structure of the field of heavy precipitation over the territory of Ukraine was adequately reproduced by the respective model of the European Centre for Medium-Range Weather Forecasts.

Published: December 2020

The present article examines the strategy of interaction of the state and small business as a factor of innovative development – which is a very topical issue, since small innovative businesses are enterprises that are on the balance of industrial property applied objects (patents, utility models, industrial designs), as well as those that systematize and protect intellectual property from commercial secrets. At the same time, the innovation activity of small business, according to the authors, is not a custom-made industry, as a rule, this industry requires more development than funding. In this connection, for the formation of innovative forms and the implementation of their activities, commercialization, expansion of strategic management, and the accession of subjects of state innovation institutions, it is necessary to create an adaptive environment for the development of small business.

Authors: Colas M. , Santarpia A. , Cannone P. , Bonnet C. 
Published: December 2020

Objectif : Cette étude qualitative vise à décrire les effets narratifs d’un protocole d’accompagnement psychooncologique s’appuyant sur les productions picturales d’une proche aidante (Mme Rose, 70 ans) accompagnant son mari atteint d’un cancer incurable.
Matériel et méthode : Il s’agit d’un protocole autour de la figuration picturale de la proche aidante composé de quatre étapes (temps) : l’entretien préliminaire (T1), une première rencontre autour de la création picturale (T2), une seconde rencontre d’approfondissement autour de la création picturale (T3), l’entretien final (T4). Nous avons utilisé le logiciel T-LAB 9.1.3 pour le calcul des associations de mots (cooccurrences) et réalisé une interprétation du récit selon l’approche humaniste/existentielle.
Résultats : Ce dispositif de recherche a permis de montrer les effets narratifs avant et après le travail artistique sur les problématiques psychiques inhérentes au vécu du proche aidant et notamment sur l’angoisse de mort. La dimension romantique du récit semble pouvoir supporter la narration tragique de Mme Rose.
Conclusion : Le « travail psychique avec la production picturale » peut permettre au proche aidant de mettre en figure l’amour et la mort à travers une narration personnelle empruntant à l’univers narratif du romantisme ses enjeux existentiels.

Published: December 2020

Background: Alopecia areata (AA) and androgenic alopecia (AGA) are the most common types of alopecias. Recently, the role of mast cells in inflammatory diseases has become the focus of many studies. However, few studies have been conducted on their role in AA and AGA. Therefore, our study aimed to quantitatively evaluate the presence of mast cells in the AA and AGA specimens.Materials and Methods: Three groups of AA, AGA, and healthy control were studied (each group with 20 subjects). Patients were randomly selected from those referred to the dermatology clinics of Shahid Beheshti University. Specimens were obtained from the scalp, and perifollicular and perivascular areas were investigated. Results: Significantly higher perifollicular and perivascular mast cell counts were seen in both AGA and AA groups compared to healthy control (P<0.001 for both). Moreover, AA patients had more frequent perivascular mast cells than the AGA group (P=0.042). Among patients aged <40 years, perifollicular and perivascular mast cell counts were not significantly different among the three groups; however, subjects over 40 years of age in both groups had significantly more perifollicular and perivascular mast cells than healthy participants. There was a significant positive correlation between disease severity and mast cell counts in both perifollicular and perivascular areas in AA patients (P=0.001 for both). Conclusion: There was a significantly increased infiltration of mast cells in AA and AGA patients, and this increase was age and severity dependent. Moreover, the increase in mast cell proliferation is more dominant in AA patients. [GMJ.2020;9:e1962]

OPTIMIZATION OF DIFFERENTIAL PRESSURE DISTRIBUTION BETWEEN GAS SUPPLY SYSTEM SECTIONS
Authors: Medvedeva O. N. , Bessonova N. S. 
Published: December 2020

The paper proposes the optimum distribution of the differential pressure between gas supply system sections and gas consumption, depending on the settlement planning and development. This provides a 10–15 % reduction in metal and material consumption of gas supply systems and a 4–5 % cost reduction. The hydraulic analysis of differential pressure distribution does not allow to purposefully distribute the calculated pressure drop. The pipeline diameter is usually selected according to the estimated gas flow rate and specific pressure loss per unit length of gas supply system sections. Then, in accordance with the State standard, the condition of compliance and non-exceedance of the obtained differential pressure is checked with the standard value. If this condition is not met, the pipeline diameter is adjusted for design reasons.This work conducts additional research into the differential pressure distribution between gas supply system sections. Materials and methods include the assessment methodology for the effectiveness of differential pressure distribution between gas supply system sections.Although many publications are devoted to the optimization of gas pressure distribution systems, the proposed solutions and the recommendations developed in this paper are fragmentary, often contradictory, since they do not consider the completeness and diversity of strategic factors.The paper shows that the pressure loss values obtained for domestic gas-based units with a reduced nominal pressure, are much less than those given in regulatory documents. According to the analysis, the settlement development, population density in gas-supplied territories, and technical conditions of gas-supplied buildings, have a decisive influence on the unit costs of gas supply systems.

Published: December 2020

Innovative heavy wagons with a 25–27 tf axle load and the freight train movement organization having a higher weight and length are being put into operation in Russia. New operating conditions of railway bridges require an assessment of bearing capacity, durability, accumulation rate of fatigue damage and reliability. The important parameters are the dynamic properties of railway bridges (frequencies and modes of natural vibrations, decay rate, dynamic stiffness).The aim of this work is to determine the dynamic interaction of trains having different structure, weight and length with a railway bridge using numerical modeling in the midas Civil bridge software. The proposed model is verified by the dynamic parameters of spans (natural vibration frequencies), which are determined during the bridge inspection using a Tensor-MS system.The modal analysis is given to the finite element model. The lowest natural modes of the bridge are determined. Based on numerical simulation of the interaction between the train and the bridge unfavorable speed of trains is calculated leading to an increase in the oscillation amplitude of the bridge span as well as in the bridge dynamic coefficient with regard to the design features of the train structure and composition.

En este trabajo se analiza la influencia de las variaciones del salario real sobre las fluctuaciones económicas enÂ Venezuela durante el período (1998-2011), para ello se realizó un análisis econométrico, utilizando modelosÂ uniecuacionales y un modelo multiecuacional (de Vectores Autoregresivos o VAR) estimados a través deÂ Mínimos Cuadrados Ordinarios (MCO) con información estadística de periodicidad trimestral, utilizandoÂ como variable proxy de las variaciones del salario real, a la variación anualizada del cociente entre el índiceÂ de remuneraciones a los asalariados (IRE) y el índice de precios al consumidor del área metropolitana deÂ Caracas (IPC-AMC), producidos por el Banco Central de Venezuela (BCV), con el propósito de analizarÂ la incidencia de dicho cociente sobre la brecha del gasto consumo final y del producto, en torno a susÂ respectivos valores tendenciales de largo plazo, aproximados por el filtro Hodrick-Prescott, como medida deÂ fluctuaciones. El análisis econométrico sugiere que existe una relación directa y estadísticamente positiva,Â entre las variaciones del salario real y las brechas del consumo final y del producto, respectivamente. SeÂ concluye sobre la base de la evidencia disponible, que las variaciones al alza de los salarios reales no generanÂ efectos globales adversos, reflejado en una disminución de la actividad económica.

Published: December 2020

Este artículo presenta un análisis de la relación entre las actividades de gestión del conocimiento y losÂ resultados operativos-financieros de la actividad empresarial durante el período 2008-2012 en 128 grandesÂ y medianas empresas colombianas pertenecientes a diferentes sectores de actividad económica. El tipo deÂ estudio es descriptivo, de carácter correlacional. La información utilizada se obtuvo de 640 directivos deÂ las empresas mencionadas. Los resultados obtenidos indican que un porcentaje bajo (27%) de las empresasÂ realiza gestión del conocimiento de forma integral y que, de esa gestión, sólo la actividad correspondienteÂ al uso del conocimiento tiene relación directa y significativa con los resultados operativos y financieros deÂ las empresas. Se concluye que la práctica de gestión del conocimiento (GC) se refiere más a la formaciónÂ de las personas, función tradicional de la gestión, que a la capacitación para la creación de conocimientoÂ que permite la construcción de capacidades diferenciadoras e innovación por parte de las empresas. EstaÂ tendencia de las empresas analizadas a ser tradicionales y conservadoras, dificulta la capacidad de las mismasÂ para que su actividad pueda responder de forma adecuada a los retos del nuevo orden económico cada vezÂ más globalizado, competitivo, cambiante e incierto.
