Digital Humanities, Citizen Science and Feminist History: The Promise and Limits of Digital Mapping
Authors: Calvini-Lefebvre Marc , Delap Lucy , Richardson Sarah , Sorin-Delpuech Claire
Published: December 2023

Abstract: One of the co-editors of this special issue of Histoire sociale / Social History, Marc Calvini-Lefebvre, is currently running a digital mapping project which seeks to crowdsource information about the sites of memory dedicated to the suffrage movement around the world and geolocate them on an open-software map. His initiative is one of many digital mapping projects launched by historians of feminism around the world as a means of spreading knowledge about the feminist past to ever-wider audiences but also of exploring new research questions via the methods of the digital humanities. To discuss the promise and limits of digital mapping, Histoire sociale / Social History invited Lucy Delap (University of Cambridge), Sarah Richardson (then University of Warwick, now University of Glasgow), and Marc Calvini-Lefebvre (Aix-Marseille Université) to participate in a forum chaired by Claire Sorin-Delpuech (Aix-Marseille Université). The conversation was edited by Marc Calvini-Lefebvre. L’un des co-rédacteurs de ce numéro spécial d’Histoire sociale / Social History, Marc Calvini-Lefebvre, dirige actuellement un projet de cartographie numérique dont le but est de rassembler des informations sur les lieux de mémoire dédiés au mouvement pour le droit de vote des femmes dans le monde entier et à les géolocaliser sur une carte en logiciel libre. Son initiative est l’un des nombreux projets de cartographie numérique lancés par des historiennes et historiens du féminisme à travers le monde afin de diffuser les connaissances sur le passé féministe auprès d’un public de plus en plus vaste, mais aussi pour explorer de nouvelles questions de recherche à l’aide de méthodes propres aux humanités numériques. Pour discuter des promesses et des limites de la cartographie numérique, Histoire sociale / Social History a invité Lucy Delap (Université de Cambridge), Sarah Richardson (à l’Université de Warwick au moment du forum mais désormais à l’Université de Glasgow), et Marc Calvini-Lefebvre (Aix-Marseille Université) à participer à un forum présidé par Claire Sorin-Delpuech (Aix-Marseille Université). La conversation a été éditée par Marc Calvini-Lefebvre.
News and the Family in Ancient Greece
Authors: Levin Itamar
Published: December 2023

Abstract: Scholarship on ancient Greek communication has most often covered military intelligence, diplomatic correspondence or news of public interest. In the present study, in contrast, I investigate the transmission of targeted information, news relevant to a circumscribed number of individuals, such as one household. I maintain that targeted reports were delivered thanks to an institution of informal reportage which was based on a quid pro quo between news-bringers and recipients. Unlike formal messengers, informal messengers voluntarily reported ex tempore alongside their other engagements in order to be compensated. This cultural environment enabled an efficient mechanism for reportage; it was likewise, however, a fertile ground for the circulation of misinformation.
Sandino in Mexico: The Perils of Anti-Imperialist Alliances
Authors: McPherson Alan
Published: December 2023

Abstract: Scholars seem to share a blind faith than anti-imperialist alliances between states and/or non-state actors are, ipso facto, worthwhile and successful. Yet guerrilla leader Augusto Sandino’s collaboration with allies from beyond his native Nicaragua brought him into a web of dependence that nearly destroyed his movement. For a few years, his support from Honduras, Mexico, and points farther away seemed to herald a far-reaching and powerful resistance movement to U.S. military interventions in Latin America. Yet the very fraying of some of those alliances compelled Sandino to leave his own rebellion and relocate to Mexico for almost an entire year in 1929–1930. There, he lost more allies than he made, as he found himself caught up in strategic and political disputes between Mexican and Soviet communists and between those same Mexican communists and the ideologically hardening Mexican state. While many ordinary Mexicans fêted Sandino, erstwhile partners isolated and nearly starved him of resources. Historians of Sandino’s Mexican trip have noted its failure, but they have remained largely unconcerned with the meanings of the trip for the larger transformations occurring on the continent or the lessons it offered for transnational, multi-party alliances. Documents from Nicaragua, the United States, and Europe demonstrate that divided ideologies and structural weaknesses hobbled the many relationships at play from the start.
Vector beam transformation and complex beam shaping using Pancharatnam-Berry phase optical elements
Authors: Kadiri Gururaj
Published: December 2023

Generating vector beams and performing intensity-preserving transformations between them are fundamental requirements in numerous optical experiments. In this letter, we investigate the potential of Pancharatnam-Berry phase optical elements (PBOEs) like waveplates and metasurfaces in fulfilling these crucial tasks. Pancharatnam Berry Phase Optical elements (PBOEs) are functional planar structures with patterned orientation of anisotropy axis. Here we establish a criterion for identifying whether a given pair of vector beams can be effectively inter-converted using a single such PBOE. Furthermore, for the pairs that satisfy this criterion, we provide the design of a waveplate that accomplishes this transformation. We also demonstrate that these devices, in conjugation with standard polarizers, are also capable of jointly as well as independently shaping the transverse-plane amplitude and phase of light beams. As an illustration of these ideas, we theoretically demonstrate that light beams comprising of a superposition of arbitrary orbital angular momentum components can be generated in a single-shot from doubly-inhomogenous waveplates.
Study of shear properties and shear model of soil-rock mixture
Authors: Du Changbo , Tao Han , Yi Fu , Meng Xingtao , Sun Di
Published: December 2023

This study investigates the shear characteristics of soil-rock mixtures, a critical factor influencing slope stability in engineering construction. Soil-rock mixtures, often exhibit poor integrity and can easily soften in water due to geological influences. The YT1200 direct shear drawing friction system was employed to conduct shear tests, analyzing the effect of varying water content and fine particle mass fraction under different normal stresses. Utilizing fractional derivatives, we formulated a fractional derivative shear model. Test results illustrated a softening phenomenon post achieving peak shear stress in the soil-rock mixture. It was found that peak shear stress is directly proportional to the normal stress, and inversely proportional to both water content and fine particle mass fraction. Additionally, the cohesion and internal friction angle decrease according to a power function with increasing water content, and non-linearly decrease with the rise of fine particle mass fraction. The proposed shear model aptly simulates the entire shear failure process of the soil-rock mixture, effectively analyzing the influence of key factors on shear characteristics. These findings contribute to the strength prediction and numerical simulation of soil-rock mixtures, thereby aiding in the design of reinforcement schemes and slope stability analysis.
Diversity of Neotropical stalked-puffball: Two new species of Tulostoma with reticulated spores
Authors: Cabral Tiara Sousa , Silva Bianca Denise Barbosa da , Vargas-Isla Ruby , Oliveira Jadson José Souza de , Ferreira Jorge Alves da Silva , Castro Laís , Martín María Paz , Ishikawa Noemia Kazue
Published: December 2023

Species of the genus Tulostoma are easily recognizable by the presence of a spore sac, with a mouth from which spores are released, attached to a stipe. Tulostoma is a species-diverse genus with a worldwide distribution, and some attempts were made to delimitate species and to evaluate reliable taxonomic-informative characteristics for species identification. However, there is a notable information gap regarding Neotropical species, especially for geographic distribution and DNA data, which hampers further understanding of the infrageneric diversity, evolution, and ecology of this genus. Based on morphological analysis, molecular phylogenetics and geographic distribution, we propose here two new species of Tulostoma with reticulated spores, from the two threatened Brazilian geographical areas, Atlantic Forest and “campos rupestres” (rupestrian grassland), as well as we provide notes on the taxonomic rank of Tulostoma exasperatum var. ridleyi.
‘Fun, fierce and frivolous’: Afrobubblegum and the possibilities of queer African love in Rafiki
Authors: Milne Rachel
Published: December 2023

Representations of Africa in film have been repeatedly haunted by a regressive single-story narrative that focuses on the ongoing effects of colonialism and racism. In Wanuri Kahiu’s 2018 feature film Rafiki, based on Monica Arac de Nyeko’s award-winning short story ‘Jambula Tree’, this pessimistic narrative is replaced by what Kahiu conceptualizes as ‘Afrobubblegum’ – at once an aesthetic preference and a political statement that produces ‘fun, fierce and frivolous’ depictions of the continent. In telling the story of two young girls who fall in love, Kahiu unsettles conventional queer narratives of control and resistance in favour of foregrounding a gentle lesbian love story. Through a focus on the narrative of queer becoming, alongside a consideration of the film’s aesthetics, I argue that Rafiki is important not just as a product that seeks to influence activism and policy, but also as a form of immersion that is in itself activist in its ability to foster a sense of belonging for queer audiences.

Being with the machine: The diremptive subject and algorithmic multiplicity
Authors: Lloyd Felix
Published: December 2023

In this article, I use Reiner Schürmann’s interpretation of Heidegger’s ‘diremption’ as a framework to examine how subjectivity is constructed in light of surveillance technology. I explore the use of algorithmic technologies – first in the context of surveillance capitalism and second in the context of art – in order to make a case for the present epoch as a site of movement towards a fundamentally multiple subject, whose singularization emerges from its embodied relationship to technology.
A haunted world: Animism, spirits and sorcery as the work of art
Authors: Montoya Adam Antonio
Published: December 2023

Animist lifeways throughout time and across cultures recognize and celebrate a sympoietic world peopled by many types of beings beyond the human. This world is considered as equally inward as it is material – indeed, ensouled – a thoroughly ‘haunted’ world of interchangeable and entangled spirits and bodies, or what I call the sorcerous quality of such a living cosmos following Deleuze and Guattari. Such a cosmovision, long considered erroneous and ‘primitive’ by the rationalist West, has seen a recent resurgence of interest and reconsideration by so-called western thought in anthropology and elsewhere. However, the presence and reality of spirits and other immaterial forces that animism embraces pose great epistemological problems for the western stance. Specifically, it is troubled by the work of sorcery and by sorcerers themselves, those who participate in the a-logical, dreamlike becomings that blur the boundaries of what is, what is actualized and what is in potentia. In an attempt to navigate this strange dimension of life, this essay will argue that the work of sorcery, as it is understood and practised by animist lifeways, is active and reserved deep within the western ‘tradition’ as the work of art. This will be evidenced in the words and work of artist Robert Smithson as they relate to the poétes maudits of late nineteenth-century Paris, the Lakota heyókȟa, Gilles Deleuze’s Bergsonism and Tim Ingold’s ‘one world anthropology’.

Authors: Amertaeva G. A. , Mamurova A. T. , Osmonali B. B.
Published: December 2023

The Asian genus Ajania Poljakov comprises about 30-40 species. Because of its complex taxonomic history with numerous movements of species between the two main groups of Artemisiinae Less., Ajania and individual genera are a particularly interesting group to study. Ajania cover most of the entire distribution range in Central Asia, with most in China, Korea, Japan and the Far East. The purpose of this research work is to clarify the morphological features of Ajania fastigiata (C. Winkl.) Poljakov, diagnostic features of vegetative organs of medicinal plants, which improves the quality of selection of raw materials for use in pharmacology. The material for the study was collected in September 2022. Morphometric data and macro-images were taken using a Levenhuk DTX RC3 remote-controlled microscope. The morphometric features were measured using “ImageJ” software The basic features were based on data from “Flora of Kazakhstan” and ‘Central Asian Explorer”. As a result of analysis of morphometric data Ajania fastigiata for Trans-Ili Alatau determined diagnostic features of vegetative organs of medicinal plants, which can improve the quality of selection of raw materials for use in pharmacology: height from 30 to 110 cm, but in most cases 50-80 cm; stem in the middle part 1.3-1.5 mm; width of septate leaves 0.7-1.0 mm; diameter of the basket 3.5-3.7 mm, stem of the basket 0.6-0.7 mm; diameter of the lower part of the tubular flower 0.5 mm, upper part 0.7 mm.
The content of photosynthetic pigments in thallomas of Parmelia sulcata Taylor in recreational areas of the city of Tver and the Spirovsky district of the Tver region
Authors: Vasilyeva A. I. , Zueva L.V.
Published: December 2023

To date, the assessment of the qualitative and quantitative content of assimilating pigments in lichen thallomas is one of the most common indicators for identifying the degree of damage to these organisms in conditions of environmental pollution. The aim of the work is to assess the content of photosynthetic pigments (chlorophyll a and b) in the thallus of Parmelia sulcata Taylor lichen in the ecosystems of Tver and the Spirovsky district of the Tver region with varying degrees of anthropogenic transformation. The study of the pigment content in the samples of lichen P. sulcata collected in the recreational areas of the city of Tver and the village of Spirovo with different levels of anthropogenic transformation and pollution. Significant differences in the content of chlorophylls a and b were found, which indicates a high plasticity of the photosynthetic system. The level of Cl a content in recreational areas is higher than in background conditions. The high variability of the values of the concentrations of Cl b indicates the priority value of the pigment system during adaptation.

The use of plants as phytoindicators of environmental pollution
Authors: Dukenbayeva A. D. , Kapbassova A. K.
Published: December 2023

This article presents the results of long-term observations of the phytoindication abilities of green spaces growing on the streets of the city. Trees and shrubs in the urban environment perform an important function of cleaning the atmospheric air from pollution by dust particles, exhaust gases from motor vehicles, and industrial processing products by accumulating heavy metal salts in their organs. Plants are able to delay strong winds and noise pollution. One of the brightest representatives with a number of phytoindication abilities is a coniferous plant, Pinus sylvestris L. The purpose of our study was to identify phytoindication abilities in trees using the example of Scots pine as well as bio-indication diagnostic signs. To achieve this goal, multiple studies were conducted with the collection of samples at five sites located in different parts of the city. As a result of the studies, the main bioindicative signs of Pinus sylvestris L. needles were revealed: chlorosis, marginal and point necrosis, shrinkage, etc. The results obtained have practical application for solving urban planning problems.
The ability to naturalize of the species from the collection “Rare and endangered plant species of Siberia”
Authors: Elisafenko T. V. , Yakk V. N. , Andreychuk D. D.
Published: December 2023

Phytoinvasions can significantly affect the functioning of natural ecosystems. Naturalization of species is the first stage of invasions. Plant introduction is a potential threat to natural ecosystems. The introduction of plants of rare and endangered species is aimed at preserving the biodiversity of the flora, and differs from the cultivation of plants having obvious economic value. The purpose of this study is to determine the species composition of plants on the territory of the collection site ”Rare and endangered plant species of Siberia”, where agrotechnical measures have not been carried out for 20 years. The mosaic of vegetation cover with the introduction of native species was established. 193 species have been identified, of which 55 species are introduced. The restoration of populations of 11 species missing from the collection in 2000 was noted. A 6-point scale for assessing the ability to naturalize introduced species was developed. The analysis of the current species composition showed that 37 species of introduced species (46 %) have disappeared from this territory since 2000. Of the identified introducers, 12 % species are decreasing their numbers, 19 % occupy within the area of cultivation earlier, 23 % of the species spread throughout the territory to varying degrees. At the same time, the ability to naturalize turned out to be unrelated to the type of reproduction of the introduced species. Half of the introducers have adapted to the new environmental conditions, and have gained a foothold in a new ecological niche.
On the identity of the species Pulsatilla astragalifolia (Ranunculaceae)
Authors: Zaikov V. F. , Shmakov A. I.
Published: December 2023

Pulsatilla is a genus of early-flowering, ornamental, partly medicinal plants, characterized by a high level of hybridization. In this connection, many of them are rare and endemic to individual territories. Several different nomenclature combinations have been made over the extensive history of the genus revising, which often causes debates between scientists. One of the cases is the taxon Pulsatilla astragalifolia Pobed. To try to solve this issue, ITS fragments of nuclear DNA of three close species (Pulsatilla bungeana C. A. Mey. ex Ledeb., P astragalifolia Pobed., P tenuiloba (Hayek) Juz.) were sequenced. Another group is formed by several clades with samples of P. bungeana and P. astragalifolia, According to the results obtained, the studied samples were divided into several groups. One group consists of two clades: the first - P. tenuiloba samples, the second - P. astragalifolia samples. Which may indicate the presence of several forms of these species. Subsequently, it is planned to study new occurrences of these species, as well as the analysis of the other DNA fragments. However, the findings indicate that Pulsatilla astragalifolia is a separate species, having both morphological and genetic differences from related species.
Siberian species on the steppe stations of the northwestern exclave of the meadow steppe
Authors: Zelenskaya N. N.
Published: December 2023

Climate warming has revived interest in the problem of species migration, changing vegetation boundaries. “Oka flora” in the Prioksko-Terrasny Nature Reserve is an isolated fragment of steppe communities in the zone of coniferous-deciduous forests. Its peculiarity is the significant participation of Siberian and Caucasian species. According to the results of long-term observations (25 years), the participation of Siberian species in steppe test sites was evaluated. In the steppe communities of the reserve, a relic floristic core is isolated, which includes species of glacial time (Carex obtusata, Draba sibirica, etc.) and species of warm Atlantic Time (Melica picta). The main part species in steppe test sites are typical steppe or meadow-steppe species, identical to the zonal meadow steppes. Modern research is devoted to identifying the features of biotopes of steppe communities. It has been established that steppe biotopes are the driest and warmest in the reserve. In recent years, there has been an expansion of the area of dense-grain cereals. Observations suggest that the ecosystem is capable of holding a pool of many species for a long time, although not all species manifest themselves in conditions of changing climatic trends. Herbaceous vegetation, depending on the hydrothermal conditions of the upper soil horizons, is the most mobile.

Published: December 2023

The ICP-MS method was used to study chemical elemental composition of the invasive species Elodea canadensis Michx. at Lake Baikal littoral sites with different degree of anthropogenic load. It is found out that dominant macroelements in E. canadensis are K > Ca > Na > P > Mg > S > Cl, dominant microelements are Fe, Mn > Si, Sr > Al, Ba, Zn > Br, B. The content of Ca, Sr, Mg, B and Si in E. canadensis samples are characterized by the least variability, and Na, P, Cl, K, V, Ni, Cu, Zn, As, Se, Br, Rb, Cd, I, Pb contents are more variable. The maximal heterogeneity in distribution is characteristic for lithophilous elements (Be, Al, Ti, Cr, Mn, Y, Zr, Nb, REE (rare earth), Hf, Ta, W, Th) as well as for Fe, Co, Sn, Sb, Bi. Maximal contents of Na, Cl, K and P associated with income of household waste waters into the near-shore zone is found in Elodea samples collected in Frolikha vent and at littoral sites adjacent to such populated areas as Gremyachinsk, Maksimikha, Nizhneangarsk. The elevated level of Zn, Cd, Pb is characteristic as well for the samples collected at the littoral sites with a high anthropogenic charge (Listvyanka settl., Bugul’deyka, Nizhneangarsk, Maksimikha village and Gremyachinsk).
Preliminary results of the study of crystals in fruits of the clade Apieae of the family Umbelliferae
Authors: Ostroumova T. A. , Zakharova E. A.
Published: December 2023

The presence, shape and distribution of calcium oxalate crystals in fruits are of great importance for the taxonomy of Umbelliferae; these traits characterize tribes and subfamilies. We are talking about prismatic crystals, large druses and globular clusters 15-25 microns in size, which are clearly visible in a light microscope. Smaller crystals were practically ignored. We studied 20 species of the Apieae clade using conventional light and polarized microscopy, scanning electron microscopy, and energy-dispersive spectroscopy. Cross sections, the surface of the commissure and seed, exocarp and endocarp fragments were studied. Large differences between species are shown - from numerous crystals in the exocarp, mesocarp or endocarp, on the commissure to their complete absence in the pericarp. Crystals occur in the form of crystalline sand, small (up to 9 ^m) drusen, naviculas, prisms, and irregularly shaped inclusions. The calcium content in the pericarp is quite high, in different areas from 1 % to 13 %, a significant part of the calcium compounds do not have birefringence. Most of the crystals contain species of subclade B3. The significance of small crystals for taxonomy remains to be evaluated. The content of silicon in the studied fruits is low, < 0.3 %.

On the biomorphology of Matteuccia struthiopteris (L.) Tod.
Authors: Semenov I. S. , Lelekova E. V. , Konovalova I. A.
Published: December 2023

Currently, many flowering plants have been studied from the standpoint of the doctrine of plant life forms, their structure, development in ontogenesis, distribution, ecology, biology and evolution. Higher spores, including ferns, remain a poorly studied group. Therefore, the purpose of this work is to clarify the features of the structural organization of Matteuccia struthiopteris in order to study the specifics of the species under the conditions of introduction to the botanical garden of Vyatka State University, located in the Ladoga-Vychegodsky South Taiga biome. In the course of the research, the modular organization of the M. struthiopteris escape system was analyzed. It is represented by elementary, universal and basic modules. There are 8 variants in the structure of elementary modules. They differ in the type of frond and their modifications, as well as the presence of subordinate roots. The universal module of M. struthiopteris is a polycyclic anisotropic upper-rosette shoot. The main module of the plant is a system of monopodially increasing polycyclic upper-rosett shoot with lateral underground stolons. As a result, a short-lived sympodium of polycyclic shoots is formed. In the course of a comparative morphological description of individual structures of the plant’s shoot system, the life form of M. struthiopteris is characterized as: vegetatively mobile, yavnopolycentric, sympodially growing rosette stolon-forming herbaceous perennial with early complete morphological disintegration; hemicryptophyte.

Published: December 2023

Iridaceae is a large family of herbaceous plants with numerous species and cultivars, diverse in the habitus and structure of aboveground and underground organs, colour and shape of the flower, as well as in terms and duration of phenological phases. The earliest flowering is specific for representatives of the genus Crocus. The purposeful formation and study of genetic collections of ornamental crops, including Crocus, was started by Federal Research Centre the Subtropical Scientific Centre of the Russian Academy of Sciences in the 1960s. A large number of cultivars have been introduced and studied. The aim of the work is to study the influence of the weather conditions on the flowering terms of crocuses in the humid Russian subtropics on the Black Sea coast of Krasnodar Territory. This unique region belongs to a Mediterranean-type climate with relatively warm winters. The work was carried out in 2021-2023 according to the methods generally accepted in the introduction, as well as those being finalized by the Centre. Mathematical processing was performed in the Microsoft Office Excel 2007 program. The objects of research are 19 crocus cultivars from the bioresource collection (FRC SSC of RAS), including Crocus vernus - 7; C. chrysanthus - 4; C. tommasinianus - 4, 1 each C. flavus, C. biflorus, C. sublimis, C. olivieri. In the course of the work carried out, it has been found that climatic conditions of the humid Russian subtropics make it possible to successfully implement introduction studies on Crocus cultivars.

Published: December 2023

The article discusses the results of biochemical studies of the content of chlorophylls a, b and carotenoids in the spruce needles growing in different conditions of the city of Ridder: control, parks, roads, zinc plant and CHP. Technogenic pollution of the Ridder air basin leads to the change in the content of chlorophylls a and b, carotenoids in the coniferous spruce. A significant decrease in the content of chlorophyll b and carotenoids in spruce needles was revealed in the following row of growing places: control -> parks -> roads -> zinc plant -> CHP. In the dynamics by age, a slight increase in the concentration of chlorophylls and carotenoids was revealed in all places of growth of fir trees.

Published: December 2023

In connection with the strengthening of human influence on vegetation, territories arose where species alien to the flora of the region appeared. Such places primarily include urban settlements. Long-term study of urban flora dynamics is of great importance and relevance. So, based on the data of V. I. Vereshchagin 30-50th XX century, a list of flora was compiled, which was further supplemented by data obtained as a result of the collection of herbarium during subsequent years to the present. From the general list of the Barnaul flora, a group of adventive (alien plants) was identified, which amounted to 211 species. Using the GIBF Global Database, the ranges of all adventitious species were determined. An absolute predominance of species with a cosmopolitan range was established. In somewhat smaller numbers, species with a Holarctic range were encountered. There are more than 90 % of such widely distributed species in the adventitious flora of Barnaul. Many cosmopolitans in a number of countries have become invasive; these are alien species whose entry and spread threaten ecosystems or native species and cause economic or environmental damage. There are 114 such cosmopolitans in the flora of Barnaul. Included in the Black Book of Siberia are 36 types of advents in Barnaul. Among them, species in Barnaul are dominated by origin associated with the northern hemisphere.

The article analyzes data on the distribution, ecological and phytocenotic confinement of the perennial tap-rooted monocarpic Saposhnikovia divaricata, which has become the object of mass illegal harvesting of root medicinal raw materials in Zabaikalsky Krai in recent years. In 2018, S. divaricata was included in the Red Book of Zabaikalsky Krai, but with category 4 “species with an uncertain status”, which led to an urgent need to study this species. In 2022, two forest-steppe (Chitinsky and Karymsky) and three steppe (Krasnokamensky, Zabaikalsky and Borzinsky) districts of Zabaikalsky Krai were surveyed, here S. divaricata raw materials are harvested from numerous abandoned fields. It was revealed that S. divaricata is confined to fallows of middle and late stages of overgrowth on the site of steppes, on light soils. S. divaricata grows on fallows in small sod grass-forb communities, where it almost always has a low and very low abundance. In the forest-steppe areas, the phytocenotic confinement of S. divaricata to communities with codominance of Potentilla acervata, Artemisia leucophylla, Poa attenuata s.l. and etc. reveals. In the steppe regions, the connection with certain dominants is weak; among these are Stipa spp., Leymus chinensis and Lespedeza juncea, Artemisia frigida, Thalictrum squarrosum. The absence of S. divaricata in fallow communities, in addition to random reasons, may be due to the early stage of restorative succession, the lack of seed sources (unplowed steppe communities with S. divaricata), and massive harvesting of S. divaricata roots over several years.
Extraordinary genetic diversity in Uzbekistan wild roses (Rosa)
Authors: Schanzer I. A. , Fedorova A. V.
Published: December 2023

We have studied a population of Rosa kokanica from slopes of the Greater Chimgan Mt. in Tashkent Region of Uzbekistan. We reconstructed a statistical parsimony network of ndhC-trnV chloroplast intergenic spacer for 34 samples from three subpopulations found in valleys of the northern, southern and south-western macro slopes of the mountain. The study revealed 19 haplotypes, one of which, the basal internal haplotype 1, was shared between the northern and southern subpopulations, while 13 unique haplotypes were found in the south-western subpopulation. We suppose that such a kind of genetic structure could arise during long lasting isolation of the subpopulations in glacial times.

Published: December 2023

We present in the article the results of an introduction test of three rare species from the genus Iris L., including I. notha Bieb. listed in the Red Book of the Russian Federation, I. sanguinea Donn and I. setosa Pall. - in the Red Book of the Irkutsk region. We made phenological observations. The condition of plants after overwintering was assessed on a 4-point scale. We also learned the seed productivity and calculated the percentage of seminification. An assessment of the primary introduction of species is given. All three species received a score of 3 points - they successfully endure winter, bloom, bear fruit, form a sufficient number of shoots. The ability to seed reproduction is defined as satisfactory. Seeds are characterized by high rates of laboratory germination. The success of introduction for I. sanguinea - 90 points, I. setosa -95 points, I. notha - 85 points. The tested species are highly decorative, are actively used in breeding, and are promising for cultivation in the Irkutsk region. We propose a broad introduction to the culture of these species, which will support the strategy of ex situ plant protection.

Study on the Comfort Properties of Knitted Fabrics Produced from Conventional and Sustainable Cotton and Polyester Fibres
Authors: Marmarali Arzu , Sevgi Mehmet
Published: December 2023

Recently, the production of organic fibres and the recycling of textile waste have become essential global issues due to the decrease in non-renewable resources and the increase in disposal costs. The aim of this work was to identify changes in the properties of single jersey knitwear produced from conventional and sustainable fibres after 20 washes. The samples were knitted from different conventional and sustainable yarns. The selected conventional fibres were 100% cotton, 50% cotton-50% polyester and 100% polyester, while the sustainable fibres were 100% better cotton, 100% recycled polyester, and 50% organic cotton-50% recycled polyester. Measurements were taken before and after 20 washes according to the relevant standards. It was found that fabric produced from 100% recycled polyester is suitable for active sportswear due to its high air permeability, and resistance to heat and water vapor. In addition, the fabric with 50% organic cotton-50% recycled polyester fibres was more suitable for cold environmental conditions due to its lowest water vapor resistance, good air permeability and high thermal resistance.
Investigation of the medium for barley (Hordeum vulgare L.) immature embryo culture
Authors: MOHAMMED Abdullah Hassn
Published: December 2023

Germination of immature embryos of interspecific crosses in vitro is the most important problem in barley breeding programs. The effect of four media types (MS, ½ MS, B-5, ½ B-5 on immature embryo culture of nine barley varieties (Sameer, Buraq, Aksad, Shuaa, Arevat, Alwarkaa, Alhadher, Amel, and Rihan) was studied by using completely randomized design (C.R.D.) with six replicates. Analysis of variance showed highly significant effects due to varieties, media, and interaction for all studied characteristics, indicated high variation among varieties and media. Aksad variety was significantly superior to all varieties for all studied traits except root number (RN). Medium of ½ B-5 was significantly superior to all media for all studied traits. Aksad interactions with media except B-5 media gave full germination with highly significant superiority over all interactions. Aksad x ½ B-5 interaction showed a highly significant superiority for shoot length (SL) and RL. As a result, ½ B-5 medium was the efficient medium for germination of immature embryos of most varieties. These varieties could be used in breeding program of interspecific crosses with wild species by using ½ B-5 medium.

Soil moisture is a key parameter of soil monitoring for observation of vegetation growth, predicting crop production, and improving water resource management. In this study, the objective is to compare the evolution of soil moisture in different mulches to determine the best mulch and its characteristics of infiltration in the soil. The experiment was conducted during the summer season in July-September 2022 on four different mulches (wood chips, sawdust, straw, mixture), and control at the experimental plot of Blida. The results showed that silt is the main matrix of the soil. The analysis of infiltration data identified modified Kostiakov as the best model of the study site, whose period of plant growth represents the phase during which we have a better infiltration under the mixture. The application of the mulch changes the moisture mainly at 15 cm and the conductivity at 10 cm. In addition, the mixture is the best mulch to conserve moisture in the soil while reducing the frequency of irrigation. The correlation between soil moisture and conductivity was overall very good. This was due to the effect of mulch, soil texture, plant root development, and capillary rise.

Fruit spirits must have an aroma of the raw material, which is balanced by ethanol.  Since many aroma compounds are more soluble in ethanol than in water, ethanol is the most important carrier of aroma compounds. The alcohol concentration seems to be crucial for the sensory profile of spirits. Alcohol content of 40% vol is the standard alcoholic strength of fruit spirits. Regulations specify a minimum alcohol content of 37.5% vol. However, ethanol reduction can result in change in sensory profile of spirits. The aim of this research is to determine whether lowering the alcohol content of spirits may make them less acceptable to customers. On this occasion, 5 pairs of fruit spirits were sensory tested: pear, plum, apple, raspberry, and grape spirits, each with a commercial and reduced alcohol concentration to 37.5% vol. The results showed that customers can recognize the difference in alcohol content of fruit spirits and dilution to lower alcohol content led to decreasing aroma for all tastes fruit spirits.  However, typicality and intensity of fruit odour and the overall note of the spirits, were very similar perceived for Williams, plum and grape spirits whereas apple and raspberry spirits showed better characteristic at higher alcohol content.
rapid and efficient DNA extraction method from high oily content seeds:
Authors: SOLIMAN Elham R. S.
Published: December 2023

Ricinus communis seeds harbor high oil and polyphenolics contents that hinder DNA extraction. Here, a rapid and efficient protocol for isolating total DNA from R. communis seeds was developed. The current method implies the use of repeated cycles of freeze/heat shock for the seed tissue to lyse the cells. DNA isolated with this protocol was successfully used as a template for PCR amplification of the internal transcribed spacer (ITS) region of the rRNA encoding gene that widely used for molecular identification of different plant species. As far to our knowledge, this study is the first one that report the efficient use of freeze/heat shock repeated cycles for isolation of a high-quality DNA from plant cells. The current protocol would support the subsequent analysis for seed lot purity analysis.
