The Marriage Ceremonies of the Inhabitants of the Mountain Villages of Kohitang

Surkhandarya is one of the ancient cradles of world civilization, with its rich history. Wide variety of national values, ancient customs, traditions, holidays, ceremonies and the unique examples of folklore has been preserved in that region. Especially, the intangible culture mountainious people of the Kuhitang in Surkhandarya region stands out. The peculiarity of this phase is that regional customs and rituals are not found in other countries and people. Among them, wedding customs hold a special place. In this article, the author, on the basis of approved materials and scientific sources, reveals the peculiar customs associated with the wedding of the mountain villages of Kuhitang.

Dynamics of social practices of migration during the pandemic of the example of Republic of Armenia

Historically rich history of Armenian migration was supplemented in 2020-2021 by new social practices, including the return of migrants to their homeland during the restrictions in the first half of 2020, and new practices of quick decision-making on emigration in the fall and winter of 2020-2021. In this article, the impact of the pandemic and the development of adaptation strategies of reactive (forced), active (making a choice from the available options) and proactive (planning the prospects for self-realization, career and professional growth and development) types. These practices are considered based on the analysis of statistical data and on the basis of our own empirical research by the method of focused interviews among Armenian families.

THC and CBD Fingerprinting of an Elite Cannabis Collection from Iran: Quantifying Diversity to Underpin Future Cannabis Breeding

Cannabis (Cannabis sativa L.) has a rich history of human use, and the therapeutic importance of compounds produced by this species is recognized by the medical community. The active constituents of cannabis, collectively called cannabinoids, encompass hundreds of distinct molecules, the most well-characterized of which are tetrahydrocannabinol (THC) and cannabidiol (CBD), which have been used for centuries as recreational drugs and medicinal agents. As a first step to establish a cannabis breeding program, we initiated this study to describe the HPLC-measured quantity of THC and CBD biochemistry profiles of 161 feral pistillate cannabis plants from 20 geographical regions of Iran. Our data showed that Iran can be considered a new region of high potential for distribution of cannabis landraces with diverse THC and CBD content, predominantly falling into three groups, as Type I = THC-predominant, Type II = approximately equal proportions of THC and CBD (both CBD and THC in a ratio close to the unity), and Type III = CBD-predominant. Correlation analysis among two target cannabinoids and environmental and geographical variables indicated that both THC and CBD contents were strongly influenced by several environmental–geographical factors, such that THC and CBD contents were positively correlated with mean, min and max annual temperature and negatively correlated with latitude, elevation, and humidity. Additionally, a negative correlation was observed between THC and CBD concentrations, suggesting that further studies to unravel these genotype × environment interactions (G × E interactions) are warranted. The results of this study provide important pre-breeding information on a collection of cannabis that will underpin future breeding programs.

Brands, Fans, and Exchanges

Although fandom has a rich history within pop culture, it is difficult to know what constitutes a fandom, what differentiates fandoms from similar phenomena as well as what different types of fandoms exist and how fandoms are formed and maintained. In this chapter, the authors define fandom and the related member actions that create and maintain fandoms, as well as delineate the concept from the similar fan-brand communities of transactional brand communities, social brand communities and brand publics. A typology for fan-brand communities is presented with two dimensions: 1) motivation for engagement; and 2) social status and relationship type. This typology can help guide researchers, brands, and marketers in effectively managing different subcultures of fans. This chapter may be used as a starting point for further understanding of fan-brand community-based relationships.

AVAILABILITY AND COMPARISON OF DATA FROM SENTINEL-1 SATELLITES IN AREAS OF INTEREST IN THE CZECH REPUBLIC AND SUDAN

The article is focused on the methodology of processing interferometric images and associated challenges with the processing. The article also contains useful links with explanations that can be used for processing data from the Sentinel-1 satellite. To emphasize the data limits of Sentinel-1, several areas of interest were chosen for comparison – in the home environment of the Czech Republic, the Bílina quarry area, and the Žatec area were selected. For subsequent comparison, arid areas with a rich history located in Sudan were selected. The colleagues of the author from the Faculty of The Environment of Jan Evangelista Purkyně University participate in expeditions there. Each of these locations is limited by different parameters – the areas in the Czech Republic are mainly limited by location because of occurring vegetation. Sudan's regions, on the other hand, are arid but are limited by insufficient coverage by capturing the Sentinel-1 satellite. To create digital height models from Sentinel-1 satellite data, it is necessary to search for data with sufficient coherence of images, and parameters of the amount of vegetation with a period between individual images play an important role. The areas were compared with each other and with the commonly available SRTM elevation model, both from a visual point of view – where digital height models and shaded surface models were created, as well as statistically using RMSE.

Along the Lines of Nonadditive Entropies: q-Prime Numbers and q-Zeta Functions

The rich history of prime numbers includes great names such as Euclid, who first analytically studied the prime numbers and proved that there is an infinite number of them, Euler, who introduced the function ζ(s)≡∑n=1∞n−s=∏pprime11−p−s, Gauss, who estimated the rate at which prime numbers increase, and Riemann, who extended ζ(s) to the complex plane z and conjectured that all nontrivial zeros are in the R(z)=1/2 axis. The nonadditive entropy Sq=k∑ipilnq(1/pi)(q∈R;S1=SBG≡−k∑ipilnpi, where BG stands for Boltzmann-Gibbs) on which nonextensive statistical mechanics is based, involves the function lnqz≡z1−q−11−q(ln1z=lnz). It is already known that this function paves the way for the emergence of a q-generalized algebra, using q-numbers defined as ⟨x⟩q≡elnqx, which recover the number x for q=1. The q-prime numbers are then defined as the q-natural numbers ⟨n⟩q≡elnqn(n=1,2,3,⋯), where n is a prime number p=2,3,5,7,⋯ We show that, for any value of q, infinitely many q-prime numbers exist; for q≤1 they diverge for increasing prime number, whereas they converge for q>1; the standard prime numbers are recovered for q=1. For q≤1, we generalize the ζ(s) function as follows: ζq(s)≡⟨ζ(s)⟩q (s∈R). We show that this function appears to diverge at s=1+0, ∀q. Also, we alternatively define, for q≤1, ζqΣ(s)≡∑n=1∞1⟨n⟩qs=1+1⟨2⟩qs+⋯ and ζqΠ(s)≡∏pprime11−⟨p⟩q−s=11−⟨2⟩q−s11−⟨3⟩q−s11−⟨5⟩q−s⋯, which, for q<1, generically satisfy ζqΣ(s)<ζqΠ(s), in variance with the q=1 case, where of course ζ1Σ(s)=ζ1Π(s).

Power, Resistance, and Place in Appalachia

This essay is an analysis of the power and resistance dynamics at work in West Virginia. Because identity constructs are often place-based, place and the meaning of place in Appalachia inform identity construction and are a powerful tool to harness for resistance. With extensive outmigration pulling Appalachians from home and local communities, the facets of identity tied to place become even more complex. Loss impacts the salience of the “idea” of home for many Appalachians. Identity that is place-based can offer a framework for building a deeper understanding of a region. At the same time, to comprehend resistance, it must have a specific context and location. Places are made up of many different identities that make creating solidarity extremely difficult. Resistance must be place-based but in order for movements to be effective, it must not rely solely on place. Appalachia has a strong history of resistance and resilience. The role of power in resistance provides context to explore West Virginia’s rich history of protest.

„Hiszpania! Jakież czarodziejskie słowo, jakże uroczo brzmi ten wyraz!" Obraz Hiszpanii na przełomie XIX i XX wieku w polskich listach z podróży

Modern Polish ideas about the Iberian Peninsula can often be summarised in slogans: azure sky, beautiful women, bullfighting, Don Quixote from La Mancha. Has this image of Spain been with us for centuries, or has it been “produced” by modern mass tourism? The aim of this article is to analyse travel texts from the 19th and 20th centuries describing journeys around the Iberian Peninsula and an attempt to answer the question of what Spain looks like in the eyes of Poles deprived of their own statehood. Is it terra incognita, an exotic country with a rich history, in which travellers find a reflection in architecture and customs, fascinated by Madrid, Barcelona, and Salamanca? Or maybe it evokes disappointment? The article compares travel letters by four Polish travellers and historians: Aleksander Hirschberg, Adolf Pawiński, Józef Wawel-Louis, and Stanisław Starża. The analysis of the letters was divided into thematic blocks: historical Polish-Spanish relations, perceptions and impressions, opinions about Spaniards and Spanish women, and cultural controversies (corrida, cockfighting).

Les manuscrits islandais médiévaux dans les romans islandais contemporains : l’exemple de L’Énigme de Flatey

In the rich history of Icelandic literature, the most famous literary genres are undoubtedly the medieval sagas and the contemporary criminal novels. However, those genres are as not as far from each other as one may think, since masterpieces of Icelandic medieval literature are sometimes summoned by contemporary authors, as is shown in The Flatey Enigma (Icelandic: Flateyjargáta), a criminal novel by Viktor Arnar Ingólfsson which is built around the story and the contents of the Book of Flatey, a famous fourteenth Icelandic manuscript. The present article provides an analysis of the place and function of the manuscripts and the medieval texts it contains: the results obtained show that their main function is to help the development of the plot, although some intertextual references also have a didactic dimension, whereas others provide information about the relations between the characters and the Book of Flatey.

Rational Protein Engineering of Bacterial N-Demethylases to Create Biocatalysts for the Production of Methylxanthines

Methylxanthines have a rich history as therapeutics and pharmaceuticals. However, natural dimethyl- and monomethylxanthines are difficult to produce synthetically, which has limited further exploration of these compounds in medicinal applications. A biosynthetic method for production of methylxanthines from whole cell biocatalysts is an attractive alternative. The bacterium Pseudomonas putida CBB5 contains a set of five enzymes, NdmABCDE, which are responsible for methylxanthine metabolism via N-demethylation to xanthine. The recent elucidation of the crystal structures of NdmA and NdmB, which remove the N1- and N3- methyl groups of caffeine, respectively, has opened new avenues to create biocatalysts for methylxanthine production. We have created a set of fifteen N-demethylase mutants and expressed them in E. coli BL21(DE3) as whole cell biocatalysts. The activity of each mutant was characterized for their affinity towards caffeine, theobromine, and theophylline. Two mutant enzymes in particular, labeled NdmA3 and NdmA4, both exhibited selectivity towards the N3-methyl group instead of the N1-methyl group. We also discovered that specific point mutations in NdmD resulted in the ability to tune the rate of the N-demethylase reaction. These new enzymes provide the capability of producing high-value methylxanthines, such as paraxanthine and 1-methylxanthine, through a biocatalytic route.
