METHOD AND MODELS FOR ESTIMATING THE INFLUENCE OF DISTRIBUTED GENERATION DEVELOPMENT ON ELECTRICITY DEMAND AND PRICE IN A REGION
Authors: Гальперова Елена Васильевна 
Published: November 2021

Актуальность статьи обусловлена переходом энергетики на путь интеллектуального развития. Одной из характеристик этого перехода является расширение перспектив децентрализованного производства электроэнергии. В новых условиях у потребителя появляется возможность изменять свое энергопотребление в зависимости от стоимости энергоресурсов, иметь собственные установки по производству и/или хранению электроэнергии. В статье кратко представлены особенности использования и технологии распределенной генерации (РГ) энергии в отдельных секторах экономики (промышленности, жилом и коммерческом секторах, на транспорте). Приведены некоторые способы определения перспективных значений мощностей РГ у потребителей. Предложен подход к моделированию и оценке влияния масштабов распределенной генерации на долгосрочное развитие региональных систем энергоснабжения. Отличительной чертой подхода является использование ранее разработанной оптимизационной стохастической модели объединенной энергосистемы макрорегиона в качестве основы для разработки ее региональной модификации и источника прогнозной информации об условиях развития региональной энергосистемы. Несмотря на то, что предложенный подход дает лишь приблизительную оценку, это позволяет очертить перспективный диапазон изменения стоимости и спроса на электроэнергию в регионе при разных вариантах развития РГ.
The relevance of the article is due to the transition of energy to the path of intellectual development. One of the characteristics of this transition is the broadening of the prospects for decentralized electricity generation. Under the new conditions, a consumer has the opportunity to change his energy consumption depending on the cost of energy resources, to have his own installations for the production and / or storage of electricity. The article briefly presents the features of the use and technology of distributed generation (DG) energy in certain sectors of the economy (industry, residential and commercial sectors, transport). Some methods of determining the prospective values of the power of the RG at consumers are given. An approach to modeling and assessing the impact of the scale of distributed generation on the long-term development of regional power supply systems is proposed. A distinctive feature of the approach is the use of the previously developed stochastic optimization model of the unified power system of the macroregion as a basis for the development of its regional modification and a source of forecast information on the conditions for the development of the regional power system. Of course, the proposed approach gives only a rough estimate, but it allows us to outline a promising range of changes in the cost and demand for electricity in the region under different options for the development of the RG.

Abstract
We report the detection of three RR Lyrae (RRL) stars (two RRc and one RRab) in the ultra-faint dwarf (UFD) galaxy Centaurus I (Cen I) and two Milky Way (MW) δ Scuti/SX Phoenicis stars based on multi-epoch giz DECam observations. The two RRc stars are located within two times the half-light radius (r

h
) of Cen I, while the RRab star (CenI-V3) is at ∼6 r

h
. The presence of three distant RRL stars clustered this tightly in space represents a 4.7σ excess relative to the smooth distribution of RRL in the Galactic halo. Using the newly detected RRL stars, we obtain a distance modulus to Cen I of μ
0 = 20.354 ± 0.002 mag (σ = 0.03 mag), a heliocentric distance of D
⊙ = 117.7 ± 0.1 kpc (σ = 1.6 kpc), with systematic errors of 0.07 mag and 4 kpc. The location of the Cen I RRL stars in the Bailey diagram is in agreement with other UFD galaxies (mainly Oosterhoff II). Finally, we study the relative rate of RRc+RRd (RRcd) stars (f
cd) in UFD and classical dwarf galaxies. The full sample of MW dwarf galaxies gives a mean of f
cd = 0.28. While several UFD galaxies, such as Cen I, present higher RRcd ratios, if we combine the RRL populations of all UFD galaxies, the RRcd ratio is similar to the one obtained for the classical dwarfs (f
cd ∼ 0.3). Therefore, there is no evidence for a different fraction of RRcd stars in UFD and classical dwarf galaxies.
Intraspecies multiple chromosomal variations including rare tandem fusion in the Russian Far Eastern endemic evoron vole Alexandromys evoronensis (Rodentia, Arvicolinae)

Published: November 2021

The vole Alexandromys evoronensis (Kovalskaya et Sokolov, 1980) with its two chromosomal races, “Evoron” (2n = 38–41, NF = 54–59) and “Argi” (2n = 34, 36, 37, NF = 51–56) is the endemic vole found in the Russian Far East. For the “Argi” chromosomal race, individuals from two isolated populations in mountain regions were investigated here for the first time using GTG-, GTC-, NOR methods. In the area under study, 8 new karyotype variants have been registered. The karyotype with 2n = 34 has a rare tandem fusion of three autosomes: two biarmed (Mev6 and Mev7) and one acrocentric (Mev14) to form a large biarmed chromosome (Mev6/7/14), all of which reveal a heterozygous state.
For A. evoronensis, the variation in the number of chromosomes exceeded the known estimate of 2n = 34, 36 and amounted to 2n = 34, 36, 38–41. The combination of all the variations of chromosomes for the species made it possible to describe 20 variants of the A. evoronensis karyotype, with 11 chromosomes being involved in multiple structural rearrangements. In the “Evoron” chromosomal race 4 chromosomes (Mev1, Mev4, Mev17, and Mev18) and in the “Argi” chromosomal race 9 chromosomes (Mev6, Mev7, Mev14, Mev13, Mev11, Mev15, Mev17, Mev18, and Mev19) were observed. Tandem and Robertsonian rearrangements (Mev17/18 and Mev17.18) were revealed in both chromosomal races “Evoron” and “Argi”.
La rencontre d’abord. Contributions d’une anthropologie romanès à l’anthropologie générale
Authors: Pontrandolfo Stefania , Solimene Marco 
Published: November 2021

L’hommage à Patrick Williams que nous proposons dans cet article est un hommage à une certaine approche anthropologique des Tsiganes-Roms qu’il a contribuée à construire avec constance et conscience : une approche originale qui fonde solidement toute proposition théorique sur l’expérience ethnographique de la rencontre réelle avec des personnes qui incarnent différentes façons de penser et de vivre notre monde. Dans cet article, nous montrerons comment les rencontres ethnographiques d’anthropologues comme Patrick Williams avec différents groupes de Tsiganes-Roms ont produit un processus de transformation de l’anthropologie des Tsiganes-Roms en une anthropologie romanès (c’est-à-dire « à la manière des Tsiganes-Roms »), participant activement au travail constant de décolonisation de la pensée anthropologique générale.
Exploring Art Therapy as a Treatment for Children with Autism Spectrum Disorder
Authors: Jeong Junhyeong , Shim Paul 
Published: November 2021

The purpose of this study is to understand the various therapies for children with autism spectrum disorder (ASD) and to discover a more effective method in connection with the research results in other fields. Art therapy was initially used at British mental hospitals to help frequently inhibited patients release creative and positive energy. As art therapy gained more attention, its usage expanded t­­­o help cure patients not only with mental disorders, but also developmental disorders like ASD. Actively used in social facilities and psychiatric treatment, art therapy is one of the most used methods to interact and understand individuals with ASD. Substantial number of papers have been published based on these various practical case studies, which proves the effectiveness of art therapy. Art therapy for children with ASD includes the following: clay, corrugated cardboard work and color mix work, drawing with crayon, paint, and pastel. These materials are frequently used to draw or create body parts, emotions, motions, and specific objects given by the instructor. From the data from research papers, clay and other tactile materials are one of the most effective materials to use to improve the condition of individuals with ASD, major depressive disorder, anxiety, and other mental disorders. Clay-based methods use the sense of touch and vision to create an abstraction process. As the usage of art therapy continues to increase in various fields, integrating effective methods among other disorders is necessary and further investigation is needed for a more effective therapy method for individuals with ASD.
El rol de la exploración geofísica en acuíferos profundos en ambientes semiurbanos y rurales en cuencas de ante arco Andino, caso de estudio en acuífero del río Ñuble, Valle Central de Chile

The hydric resource coming from groundwater has a strategic nature at global scale, within a context of overpopulation and over exploitation of the resource and climate change. Chile doesn’t scape to it, where climate models predict a drought for most of the country, including partially, the agriculture region of the Central Valley between Santiago and Puerto Montt. The adaption process to global change demands the exploration new sources of provisions of this resource, being strategic the one coming from aquifers. To date, the knowledge of these resources is limited to depths below 200 m in each aquifer. However, in the Central Valley between Santiago and Chiloé, the geophysical evidences allow to infer the existence of a thick volcano-sedimentary basin growing in thickness southward well above 500m, with good potential for occurrence of large groundwater resources.
The characterization of deep aquifers, 200-1,000 m of depth, demands to have an exploration tool economic, non-invasive, and reliable, able to be applied in semi-urban and rural environments, where the water resource need is higher.
The geophysical methodologies meet these characteristics and have been applied in Chile and elsewhere as an exploration tool of ground water resources. However, its application have not been described in Andean environments, of large population and/or agro-industrial activity. In consequence, the present work raises a methodological strategy for the characterization of groundwater resources, in particular for the detection of deep resources. We propose the application of a combination of complementary geophysical techniques, including electrical, electromagnetic, and gravimetric methods (to determine the aquifer geometry) along with complementary techniques, like magnetometry, to reduce interpretation ambiguity and , constrained by hydrogeological information and petrophysics of rocks and sediments of the basin and basement. Complementary, we include an analysis of the potential effects of cultural noise and its effects on geophysical observations, given the focus of exploration in semi-urban and rural places.
With the aim to validate the proposed methodology we use as a case study the aquifer of Ñuble river, in the Ñuble region, Chile. This aquifer properly represents an Andean forearc environment in rural and semi-urban condition, and potentially hosting a deep seated aquifer. The results allow the characterization of an aquifer with hydrogeological potential between 50 and 300-500 depth, overlying a sedimentary basin of more than 1,000 m thickness. The application of the proposed methodology for the exploration of groundwater resources will provide, in consequence, the recognition of a vital relevance resource for the sustainability of Chile during the following decades.
A Cultural History of Color in the Age of Enlightenment
Authors: Wolf Kirsten 
Published: November 2021

Volume 2 A Cultural History of Color in the Medieval Age covers the period 500 to 1400. The medieval age saw an extraordinary burst of color - from illuminated manuscripts and polychrome sculpture to architecture and interiors, and from enamelled and jewelled metalwork to colored glass and the exquisite decoration of artefacts. Color was used to denote affiliation in heraldry and social status in medieval clothes. Color names were created in various languages and their resonance explored in poems, romances, epics, and plays. And, whilst medieval philosophers began to explain the rainbow, theologians and artists developed a color symbolism for both virtues and vices.
Color shapes an individual’s experience of the world and also how society gives particular spaces, objects, and moments meaning. The 6 volume set of the Cultural History of Color examines how color has been created, traded, used, and interpreted over the last 5000 years. The themes covered in each volume are color philosophy and science; color technology and trade; power and identity; religion and ritual; body and clothing; language and psychology; literature and the performing arts; art; architecture and interiors; and artefacts.

Introduction: Rheumatic mitral valve disease (RMVD) is associated with autoimmune heart valve injury. Parathyroid hormone (PTH) and vitamin D are two essential molecules that have effects on the immune system. In this study, we aimed to evaluate the relationship between PTH and vitamin D in patients with RMVD.
Patients and Methods: We investigated 81 patients with RMVD and 75 healthy subjects. According to Wilkins score, baseline clinical, laboratory, and echocardiographic parameters were recorded, and all RMVD patients were analyzed. Multivariate logistic regression analysis was performed between the groups.
Results: Vitamin D levels were significantly low in the RMVD group. Patients were stratified according to Wilkins score [Wilkins score<7 (n= 50) vs. Wilkins score ≥7 (n= 31)]. Age, BMI, and PTH were significantly higher, and mitral valve area was significantly lower in Wilkins score ≥7 patients. In multivariate analysis, age (OR= 1.052; 95% CI 1.005-1.100, p= 0.028) and PTH (OR= 1.017; 95% CI 1.000-1.033, p= 0.047) were found to be independent predictors of high Wilkins score.
Conclusion: This study showed that vitamin D levels were low in patients with RMVD. According to the Wilkins score, PTH levels were significantly high in patients with a high Wilkins score. Changes in PTH and vitamin D levels may trigger inflammation and be responsible for valve damage.

The aim of this study was to produce high protein diet for growing children from yellow maize, soya bean, pumpkin seed and fish meal. The raw materials were subjected to different processing techniques. The yellow maize (YM) was blended with different proportions of soya bean (SB), pumpkin seeds (PS) and fish meal (FM) with a view to formulating a high protein diet to address protein Energy Malnutrition. The formulated food Blends were; Blend 1 (70 % YM: 30 % SB), Blend 2 (70 % YM: 30 % PS), Blend 3 (70 % YM: 30 % FM), Blend 4 (70 % YM: 20 % SB :10 % PS), Blend 5 (70 % YM: 15 % SB: 15 % FM), Blend 6 (60 % YM: 20 % PS: 20 % FM), and a therapeutic milk (F-100) was used as a control diet. The raw materials and the food Blends were assayed for proximate, mineral, vitamin content and amino acid profile. The data obtained were analyzed statistically. The results of the proximate composition showed significant (p<0.05) decrease in moisture, protein, total fat and fibre contents of the fermented yellow maize, roasted soya bean and pumpkin seed while that of the dried fish showed significant (P<0.05) increase. The results shows that food Blend 6 had highest values for protein (17.77±0.09 %), total fat (6.00±0.27%) and total energy (388.10±0.29 Kcal/100g). A Significant (P<0.05) difference was observed in the mineral element content of yellow maize and fish meal after fermentation and drying respectively, while an increase was observed in roasted soya bean and pumpkin seed. The food Blend 5 recorded higher value for Na, and K, while the control diet had higher value for P, Zn, Fe and Cu. An increase in B-group vitamins, and vitamin C, were observed in the samples, while decreased in fat soluble vitamins A and E were observed in fermented yellow maize and dried fish, while decrease was observed in roasted soybean and pumpkin seed. The control diet had higher value for all the vitamins analyzed compared to the food Blends, except for vitamin A and E. The result of the amino acid profile showed that the levels of the essential amino acids were increased in the fermented yellow maize, and dried fish, while a reduction was observed in roasted soya bean and pumpkin seed. However, all the prepared food Blends were enhanced in terms of essential amino acid, but more enhanced in food Blend 6, followed very closely by food Blend 5. The amino acid profile of the control Blend was higher than those of the food Blends1, 2, 3 and 4. Thus, the high energy and protein contents of the formulated diets are adequate in the management of PEM.

The importance of this research arises from its attempt to correct the weaknesses encountered by most developing countries namely The Republic of Sudan due to the absence of strategies that set leading guidelines for successful privatization processes. This research provides a full answer to a crucial question] How can successful privatization be achievedin developing countries? [The objective of this research extends to help privatization decision makers to avoid problems arising from application, as well as enhancing privatization programs by offering strong support to achieve their targets. Themethodology adopted by this research is a combination of many research methodologies such as descriptive, analytical, comparative, inductive and deductive approaches. The research findings are many, namely privatization is a complicated phenomenon, andat the same time, represents a junction where interests of conflicting parties meet corruption & cronyism that may accompany the execution of privatization has aggravated more economic & social problems. The recommendations proposed by this research include, more attention should be paid to promote awareness (among the top executive authorities, senior government staff & privatization process executors) to the risks associated with improper designing & incorrect implementation of privatization. Support and follow-up from the top government authorities to privatization programs will help minimize the problems that might hinder application. Governments to provide their countries with thenecessary prerequisites for successful privatization should adopt proper actions
