Published: August 2020

Focus is on scientific and economic background, and implementation of resource savingmeasures in the municipal economy, which would allow significant reduction of negativeimpacts on the environment caused by municipal facilities and other infrastructures, as well asto increase economic efficiency in municipal economy through resources and financial flowsmanagement. The new approach to the evaluation of resource saving technologies for needsof municipal economy has been developed on basics of economics and environmentalindicators.The aim of this research paper is twofold: (I) to determine precautionary measures leading toreduction in public water use, and (2) to develop appropriate indicators and criteria forassessing the sustainability of measures for minimization of water use. The proposedindicators will help owners of office buildings and investors to make decision inimplementation of such environmentally sound technologies as resource saving measures. Inorder to achieve the goal of this research, extensive analysis of data was done. Principal datasources were the Ukrainian National Surface Water Monitoring reports, provided by RegionalOffice of the National Hydro-meteorological Service in Kharkiv, databases on point sourcesemission provided by Kharkiv Municipal Water Works (Municipal Enterprise "KP 'Yoda"')and Wastewater Treatment Facilities (Municipal Enterprise "Kharkivkomunochystvod"), datafrom the Kharkiv Municipal Energy and Heat Supply Company ("Kharkivteploenergo"), andthe State Committee of Statistics' year fact books.Options for dealing with water minimization are generated according such approaches aschanges of human behavior, water control implementation and water saving technologiesintroduction. Criteria were developed by the result of preliminary research of waterminimization factors. The approach to criteria development is based on hierarchy, consistingof small number of high level primary criteria, which would cascade down to a large numberof more specific, secondary criteria. According to the chosen criteria the necessary datashould be collected to use records, individual and group interviews, social survey. After thedata collection, indicators development the procedure of the decision support will be doneusing the multi-criteria analysis.

Authors: Mahler Claudio Fernando , Loureiro Saulo Machado
Published: August 2020

The article consists of the application of a new rating methodology for final disposal of urbansolid waste (USW) by evaluating the conformity of geotechnical and environmental aspectsduring the implementation and operating processes. The IQS was proposed when introducingthe concepts of Environmental Management, in accordance with ISO 14001, to the LandfillQuality Index (IQA) [I], developed from the Waste Quality Index (IQA) proposed by [2]. Thestudy focused on the implementing and operating processes, as well as on the control ofimpacts on the environment and on pollution prevention. Fifteen sites were assessed toconfirm the hypothesis. They were rated as inadequate, controlled, adequate andenvironmental conditions, in accordance with indices obtained with intervals between zeroand ten points. It could, therefore, be concluded that in an inventory of rating USW disposallandfills, the use of ISO 14000 as an analytical tool may be extremely helpful to enhanceassessment methods. Moreover, environmental management concepts contribute to reducingenvironmental pollution and, consequently, the associated environmental impacts.
A comparison between EU and Brazilian water policies: the use of macroinvertebrates
Authors: Vieira Abel Silva , Gomes Guilherme Araujo , Macedo Rene Lebarbenchon
Published: August 2020

Water management has traditionally looked at the physical-chemical measurements which arenot enough to protect the ecosystems in a more detailed watershed management. TheEuropean Union (EU) and Brazil have been attempting to improve their water status by theimplementation of the Water Frame Directive (WFD) and the Brazil's National WaterResources Plan (PNRH) respectively. Despite of many similarities between the policies, theymainly differ in the use of bioindicators. Macroinvertebrates are the most common biologicalindicator used to show disturbances in the water bodies. The aim of this paper is to explainhow macroinvertebrates have been adopted to classify the ecological status of the waterbodies by the Brazilian and EU water policies. In the WFD it was defined the AQEMbiomonitoring program, which uses macroinvertebrates index. On the other hand, the PNRHdoes not require biomonitoring. The use of bioindicators is the main difference between bothwater management policies. It reflects the concept of the water as a resource in Brazil and asan ecosystem in the EU.
Influence of sodium lignosulfonate on loamy soil and cucumber plants
Authors: Yurkevich Maria , Ikkonen Elena
Published: August 2020

Sodium lignosulfonate is a water-soluble by-product obtained by the sulfite method of cellulose production. In a model experiment, the authors investigated the effect of sodium lignosulfonate on certain agrochemical parameters of sod-podzolic loam soil and on the physiological parameters of cucumber plant development.
Sodium lignosulfonate was added to the soil in concentrations 0 %, 1 %, 2,5 %, 5 % and 10 % of the dry soil weight. The samples were incubated at a constant temperature (23 °С) and a constant humidity of 70 % for 90 days.
Adding lignosulfanate to the model soil in small concentrations (1 and 2.5 %) significantly increased the content of potassium (from 169.7 mg/kg in the control to 389.1–431.6 mg/kg, respectively) and exchange cations, but reduced the nitrogen content regardless of the dose. The concentration of Mg, CA and Na increased by 3.9…7.8 times, which had an alkalizing effect on the soil. At a concentration of 2.5 % lignosulfonate, the pH of the salt solution increased by 1.26 units. At the same time, the concentration of the buffer solution significantly increased, which was manifested in the physiological response of plants.
Lignosulfonate reduced the accumulation of plant biomass and proportion of roots in the total mass. With an increase in the concentration of lignosulfonate in the soil, the degree of inhibition of growth processes increased. Lignosulfanate did not affect the stomatal regime of leaves and transpiration losses of water, but it reduced the water content in the leaf depending on the concentration. Photosynthetic activity of plants was partially suppressed in conditions of high lignosulfonate content in the soil. Lignosulfonate did not enhance plant tolerance to low temperature.
Dependence of physico-mechanical characteristics and safety factor of the soil mass on the spacing of vertical pillars of crushed stone
Authors: Artyushenko Igor
Published: August 2020

In the design, construction and further operation of communication lines on permafrost soils, the most urgent task is to ensure the reliability of the foundation of the structure. The complexity of construction in the North is due to the presence of permafrost soils in the foundations of buildings, a large number of natural barriers, extreme climatic conditions and lack of infrastructure.
In this regard, the choice of structural, technological and organizational solutions for the development of transport infrastructure, including for railways and, first of all, a deformability forecast, measures to ensure the stability of the soil base and the development of rational organizational schemes for their implementation, should be economically feasible, optimal or close to optimal for a particular engineering structure and the region of its location.
To ensure stability and sustainability of the soil base of the structure on the Northern Latitudinal Railway section of the new Obskaya-Salekhard railway line, PK 01+50 – PK 06+50, the author proposes a solution to strengthen the base soil with vertical columns of crushed stone.
This article shows the effect of vertical columns of crushed stone on the strength characteristics of permafrost soils of the base of the structure. The dependence of the strength characteristics of the soil base on the different steps of the placement of vertical columns of crushed stone is shown. The conclusion is drawn about the most optimal spacing step according to the results of calculations and comparison of various steps of arranging vertical pillars from crushed stone.
The results presented in the article are part of the dissertation research I. Artyushenko «Reinforcement of the subgrade base with vertical columns of crushed stone in areas with permafrost soils».
Comparative analysis of ways to protect bridge structures from external influences
Authors: Berlov Stanislav , Ovchinnikov Ilya
Published: August 2020

Due to the fact that modern bridge construction sets itself the task of building new bridge structures in seismically active areas where earthquakes or other external impacts are permanent, there is an urgent question of protecting the structure from these impacts. This article is devoted to the analysis of ways to protect the bridge structure from external influences. The author analyzes these methods on the basis of publicly available data from companies engaged in the production of structures that prevent external influences, as well as on the basis of modern regulatory documents. The article presents such methods of protection as: deformation seams, support parts, dampers of various modifications and vibration dampers of shrouds. To choose the optimal method, both from the economic side and from the technical side, it is necessary to make verification calculations for static, dynamic and seismic effects, study the geological characteristics of the construction site, conduct mandatory tests of the structures used, as well as use regulatory documents and guidelines for testing and using seismic isolation devices. Also, the author of the article emphasizes that it is important to study ways to protect bridge structures not only in domestic practice, but also in foreign practice.

Published: August 2020

The national project “Safe and high-quality roads” is aimed at the development, creation and effective use of intelligent transport systems. Today, there are many technical solutions to improve road safety, as well as optimize the process of organizing traffic. Often, these solutions lie not only in the plane of design, in the use of technical means for organizing traffic, in reconstruction of the existing street-road network, but also in the use of intelligent transport systems.
The article has developed a concept for the development of a road-road network in Khabarovsk, in connection with the adoption by the Government of the Khabarovsk Territory of a decision on the construction of a transport interchange at the intersection of Voronezh-Bolshaya Streets in Khabarovsk, as part of the national project “Safe and High-Quality Roads” in the Khabarovsk Territory. The collection and analysis of statistical data, over a five-year period, on the types of frequency of occurrence of reported road traffic accidents. Visual and grapho-analytical methods identified the focus of the concentration of traffic accidents at the considered site of the road network of the city of Khabarovsk. Based on the method of conflict points, factors that influence the accident rate of an existing section of the road are studied. Several options for improving the quality and safety of traffic are considered: changing the number of lanes, regulating the traffic light, building a multi-level traffic intersection. Using modern software systems, based on methods of mathematical modeling, for several options developed models of traffic flows, identified the maximum possible comfortable and safe traffic conditions. Substantiated recommendations are given for improving the quality and safety of road traffic by improving the existing road situation.
Influence of mounting joints of sections of a collapsible bridge on his stress-strain state
Authors: Tomilov Sergey
Published: August 2020

Temporary bridges are necessary to ensure movement during the construction or repair (reconstruction) of capital bridge structures, operational communication of interrupted tracks in various emergency situations, for one-time or seasonal transport communications. For this purpose, reusable mobile prefabricated structures are advisable. Inventory sets of collapsible bridges were designed and manufactured primarily in the interests of the military department, but are currently widely in demand and are used in the civilian sector of bridge building because of their economy, mobility, and accessibility in transportation.
Among others, including modern collapsible bridge designs, the middle automobile collapsible bridge (CAPM), developed in 1968 and modernized in 1982 for the needs of the USSR Ministry of Defense, occupies a special place. In the process of withdrawing the CAPM sets stored in storage to the civilian construction sector, a significant demand for these structures was found to be due to their following advantages: complete staffing with all elements of the bridge, including supports; the possibility of overlapping spans of 18.6, 25.6, 32.6 m with the dimensions of the driving bed 4.2 m for single-track and 7.2 m for double-track passage Passport carrying capacity is designated as 40 tons for single-track passage and 60 tons for double-track passage.
Since, according to a number of geometric and technical parameters, CAPM designs do not fully comply with the requirements of modern standards for capital bridges, their application is mainly oriented as temporary.
It should be noted that with minor refinement – the installation of modern fences and a double-track transverse arrangement of sections for single-lane traffic, it is possible to achieve compliance with the required geometric parameters of the driving bed and the total lifting capacity for bridges on public roads of IV and V of technical category.
The article considers the design feature of the pin mounting joints of sections of a collapsible span as a factor determining the carrying capacity, the nature of general deformations and, as a result, affecting the transport and operational characteristics of the bridge structure.
The purpose of this study is to analyze the operation of the pin mounting joints of the sections of the spans of the CAPM with the assessment of the stress state of the elements of the connection node. We consider the novelty in the consideration of the issue to be an assessment of the strength of the elements of the pin joints and its effect on the general deformations – the deflections of the main beams.
Desinformação e mensagens sobre a hidroxicloroquina no Twitter
Authors: Araujo Ronaldo , Oliveira Thaiane
Published: August 2020

Introdução: A pandemia do novo coronavirus trouxe consigo um forte aliado responsável por tornar cada vez mais difícil o enfrentamento da doença, a desinformação científica. Opiniões negacionistas, teorias conspiratórias, oportunismo político são alguns exemplos de uso malicioso por trás da disseminação de informação sobre o vírus, seus efeitos, formas de tratamento e prevenção. Método: por meio de um estudo infodemiológico a pesquisa analisa o compartilhamento de informações no Twitter sobre a hidroxicloroquina, o medicamento que tem ganhado destaque quando se fala de um possível tratamento farmacológico da doença. Os dados foram coletados via Netlytic por meio do monitoramento da hashtag #hidroxicloroquinaja entre os dias 11 a 30 de maio e são analisados a partir da análise da rede de interação em torno do compartilhamento, compreensão dos termos frequentes e categorização das postagens. Resultados: Foram analisados 3.714 tweets e identificados 2.089 usuários, dos quais apenas 678 (32,4%) mantiveram algum tipo de conexão com outros usuários na rede. Os termos frequentes e sua distribuição indicam que a questão é protagonizada mais por aspectos políticos do que de saúde, com maior concentração de mensagens em poucos usuários e um grande número responsável por sua viralização. As categorias mais comuns foram “Ataque a agentes políticos” e “Descrença nas instituições epistêmicas”. Conclusão: No contexto estudado percebe-se que os valores da própria cultura científica, como reconhecimento e autoridade, vão ganhando novas camadas informacionais em disputa política em um momento no qual as instituições epistêmicas estão em declínio.

Introgression Among Three Western North American Bilberries (Vaccinium section Myrtillus)
Authors: Beeler Reese B. , Sharples Mathew T. , Tripp Erin A.
Published: August 2020

Abstract—Despite being dominant elements of understory communities in the coniferous forests of western North America, phylogenetic relationships among bilberries (Vaccinium section Myrtillus) remain unresolved. Morphological delimitation among most western
bilberry species is tenuous, and traditionally employed molecular sources of phylogenetic information have yielded insufficient variability. Moreover, these species are hypothesized to have undergone extensive introgression. We used RADseq data analyzed with maximum likelihood species tree
estimation and Patterson’s D-statistic analyses to examine the influence of introgression on relationships among Vaccinium myrtillus, V. scoparium, and V. cespitosum. Additionally, we used these data to assess whether the populations of V. myrtillus disjunct
between North America and Eurasia are monophyletic and should continue to be recognized as conspecific. Significant genome-wide introgression, as determined through D-statistic analyses, was detected between North American samples of V. myrtillus and V. cespitosum, and
to a lesser extent, between V. myrtillus and V. scoparium. No significant D-values were detected between V. scoparium and V. cespitosum. Accessions of Vaccinium myrtillus from Eurasia and North America were recovered as non-monophyletic, prompting
our proposed resurrection of V. oreophilum for North American material. The long-assumed sister species relationship between V. oreophilum and V. scoparium was not recovered in our analysis. Instead, V. oreophilum and V. cespitosum were inferred to be sister
taxa. This study reveals considerable introgression detectable in the evolutionary history of western North American bilberries and demonstrates the utility of RADseq data to resolve species level relationships in groups that undergo reticulate evolution such as Vaccinium.
Neptunia windleriana: A New Polyploid Species of Neptunia (Leguminosae) from Brazil Recognized by Anatomy, Morphology and Cytogenetics
Authors: Silva Juliana Santos , Carvalho Márcia Santos , Santos Géssica Souza , Braga Francyane Tavares , Gomes de Andrade Maria José , de Freitas Mansano Vidal
Published: August 2020

Abstract—Neptunia windleriana, a new polyploid species of the pantropical genus Neptunia, is described and illustrated. This plant is endemic to the state of Bahia, Brazil, and is found in areas of Caatinga near the São Francisco River. Among
the species occurring in Brazil, it is most similar to N. plena, a widespread species, by having a gland on the petiole, but it differs mainly by the number of pairs of pinnae and leaflets, shape of the spike in bud, and the size of the peduncles. It is morphologically distinct from
all other species of the genus by the combination of prostrate subshrub habit, smaller leaves, shorter petiole and shorter rachis length, few-flowered, globose spikes, 10 stamens, and glabrous ovary. The presence of monocrystals in the bundle sheath cells of the bracts of N. windleriana
is recorded here for the first time for the genus, together with the chromosome number (2n = 56 vs. 2n = 28, ∼52, 54, 56, 72, 78 for three other species of the genus occurring in Brazil), it can be also used to identify the species. The epidermis of the stipules, leaflet,
and bracts of N. windleriana is uniseriate, with paracytic stomata. The vascular system has collateral arrangement with the vascular bundles covered by a sheath, with or without isolated monocrystals. Our data support earlier hypotheses that Neptunia has a base number
of x2 = 14 which seems to be a secondary basic number that originated from an ancestral stock with x1 = 7 and underwent karyotypic evolution by polyploidy. A key to the Brazilian species of Neptunia as well as anatomical, cytogenetic, taxonomic,
and geographic distribution data, ilustrations and photos are provided.
Morphology and Affinities of Ampelocissites Seeds (Vitaceae: Ampelopsis clade) from the Paleogene of Texas, USA
Authors: Manchester Steven R.
Published: August 2020

Abstract—The type material on which the fossil genus name Ampelocissites was established in 1929 has been reexamined with the aid of X-ray micro-computed tomography (μ-CT) scanning and compared with seeds of extant taxa to assess the relationships of these
fossils within the grape family, Vitaceae. The specimens were collected from a sandstone of late Paleocene or early Eocene age. Although originally inferred by Berry to be intermediate in morphology between Ampelocissus and Vitis, the newly revealed details of seed morphology
indicate that these seeds represent instead the Ampelopsis clade. Digital cross sections show that the seed coat maintains its thickness over the external surfaces, but diminishes quickly in the ventral infolds. This feature, along with the elliptical chalaza and lack of an apical groove,
indicate that Ampelocissites lytlensis Berry probably represents Ampelopsis or Nekemias (rather than Ampelocissus or Vitis) and that the generic name Ampelocissites may be useful for fossil seeds with morphology consistent with the Ampelopsis
clade that lack sufficient characters to specify placement within one of these extant genera.
Cuscuta sect. Californicae (Convolvulaceae) Revisited: ‘Cryptic’ Speciation and Host Range Differentiation
Authors: Costea Mihai , ElMiari Hiba , Farag Roula , Fleet Christopher , Stefanović Saša
Published: August 2020

Abstract—Cuscuta californica complex (sensu lato, s. l.) is a western North American group of species in which the infrastaminal scales are reduced, making the morphological delimitation of species particularly challenging. A revision of this group was prompted
by the discovery of an apparent new species from central California based primarily on molecular means. Driven by this finding, the morphological limits of C. californica s. l. species were comprehensively re-evaluated through a morphometric study. DNA sequences from plastid (trnL‐F
region and rbcL), nuclear ribosomal ITS and 26S rDNA, as well as a low-copy nuclear pentatricopeptide repeat (PPR) gene were used to reconstruct evolutionary relationships among taxa. Last but not least, the host range of relevant taxa was determined using herbarium specimens. Molecular
results strongly supported the new species, C. difficilis, which was found to be morphologically separated from C. brachycalyx only by subtle calyx lobe and corolla tube shape differences. Despite sharing some of the hosts, all the members of C. californica s. l.
exhibited a differentiation of their host ranges. An identification key and description of the new species were provided together with a discussion on the systematics and host range of C. californica s. l.. Hybridization, accompanied by plastid capture, was suggested as a possible mechanism
of speciation for C. brachycalyx.
Siphocampylus nebularis (Campanulaceae, Lobelioideae), a New Endemic Species from the Atlantic Forest in Southern Brazil
Authors: Coelho Guilherme Peres , Vieira Iganci João Ricardo , Sfoggia Miotto Silvia Teresinha
Published: August 2020

Abstract—Siphocampylus nebularis is a new species endemic from the Serra do Mar mountain range in the Paraná state, Brazil. It is morphologically close to S. fulgens due its alternate phyllotaxis, sparsely denticulate leaves, and flowers
with reddish corolla tube, differing mainly by the shorter corolla tube, longer calyx lobes, and coriaceous leaves observed in the new species. The new taxon is here described and illustrated. We also propose the inclusion of S. nebularis in the IUCN Red List as an endangered (EN) species
due its narrow distribution and the decline of the quality of its habitat.
Temperate Eurasian Origins of Hawaiian Chenopodium (Amaranthaceae), Plus Description of a New Subspecies Endemic to Moloka‘i
Authors: Cantley Jason T. , McDonnell Angela J. , Branson Jennifer , Kobara Joseph , Long Stephanie R. , Garnett William , Martine Christopher T.
Published: August 2020

Abstract—Hawaiian taxa of Chenopodium are tetraploids and are distinguished from other members of the circumglobally distributed genus by minute morphological characters. Because of these reasons, the geographic origin of Hawaiian Chenopodium has remained
unclear. Across the Hawaiian Archipelago, taxa of Chenopodium are morphologically variable and grow in highly disparate xeric habitats, especially in terms of precipitation, temperature, wind, salt spray, and solar irradiation. Habitats include dry subalpine shrublands, sandy beach
strands on atolls in the Northwest Hawaiian Islands, dry to mesic forests, and precipitously tall sea cliffs of northwestern Moloka‘i. From the Moloka‘i sea cliffs, which are battered by high energy winds, salt spray, and strong seasonal precipitation, we describe C. oahuense
subspecies ilioensis as segregated from the widespread Hawaiian C. oahuense sensu lato. Morphometric analyses distinguish C. oahuense subsp. ilioensis by its strongly prostrate to scandent habit, thick succulent leaves, smaller average leaf size, limited
lobing of the laminar margins, and smaller seeds. Phylogenetic analyses using two DNA regions (the plastid gene rpl32-trnL and nuclear ITS) of newly sequenced individuals of C. oahuense s. l. and C. oahuense subsp. ilioensis plus outgroup taxa support the monophyly
of Hawaiian Chenopodium and reveal a geographic origin of temperate Eurasia. Two equivocal hypothetical scenarios are discussed regarding the likely sequence of events leading to the arrival of Chenopodium in Hawaiian Islands followed by possible in situ speciation of the Moloka‘i
endemic C. oahuense subsp. ilioensis.
A New Species of Cryptanthus (Bromeliaceae, Bromelioideae) in the Brazilian Atlantic Forest north of the São Francisco River, and its Contribution to the Taxonomy of the Genus
Authors: Cavalcanti Ferreira Débora Maria , Louzada Rafael Batista
Published: August 2020

Abstract—Cryptanthus cinereus D.M.C. Ferreira & Louzada, a new rare species of Bromeliaceae restricted to northeastern Brazil, is described and illustrated. Cryptanthus cinereus is a rupicolous plant that occurs in the Atlantic Forest
on the top of a rocky outcrop and is known only from a single record. This new species is morphologically similar to Cryptanthus felixii, but differs mainly by its narrowly triangular leaves that are wider at base, primary bracts with adaxial surfaces densely lepidote (vs. glabrous
or glabrous with base densely lepidote), shorter flowers (39‐52 mm), sepal lobes lanceolate, with shorter connate sepals (1.6‐5 mm) and petals (1‐1.2 mm). An identification key to Cryptanthus cinereus and other species that occur in the Atlantic Forest north
of the São Francisco River is provided. In addition, two species complexes are characterized for the area.
Comparative Anatomy of Cypselae in the Complex Group Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus: Contributions to the Systematics of Vernonieae (Compositae)
Authors: Marques Danilo , de Oliveira Franca Rafael , Angulo María Betiana , Via do Pico Gisela Mariel , Dematteis Massimiliano , Marzinek Juliana
Published: August 2020

Abstract—Circumscription of genera in the tribe Vernonieae is complex due to overlapping morphological features among genera such as Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus. These genera have been segregated from the genus
Vernonia s. l., but their classification remains questionable because they lack clear diagnostic characters to contribute to this classification. Several studies have demonstrated the importance of the anatomy of cypselae for classification in Compositae; cypselae provide diagnostic
characters for some genera. We studied the anatomy of the cypselae, including pericarp, callus, carpopodium, and pappus of Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus, evaluating their potential for clarifying systematic problems in these genera. Our
study demonstrated the cypselae features are uniform, and they do not contribute diagnostic characters useful in generic circumscription; however, cypselae anatomical characters do segregate some species. Our data also suggest that Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus
should be circumscribed in a single genus Lepidaploa.

A Revised Sectional Classification of Plukenetia L. (Euphorbiaceae, Acalyphoideae) with Four New Species from South America
Authors: Cardinal-McTeague Warren M. , Gillespie Lynn J.
Published: August 2020

Abstract—We present a phylogenetic classification for Plukenetia (Euphorbiaceae, Acalyphoideae) based on morphology and molecular phylogenetic studies using nuclear (ETS, ITS, KEA1 introns 11 and 17, TEB exon 17) and plastid (matK, ndhF,
psbA-trnH) DNA data. Plukenetia comprises 25 species divided into six sections, with three new sections and four new species described here. The circumscription of Plukenetia is unaltered from recent treatments and we continue to recognize Romanoa as distinct. The
sections of Plukenetia correspond with the subclade system proposed by Cardinal-McTeague and Gillespie (2016): P1 = P. sect. Fragariopsis comb. et stat. nov.; P2 = P. sect. Penninerviae sect. nov.; P3 = P. sect. Plukenetia; P4 = P. sect.
Angostylidium; and P5 = P. sect. Hedraiostylus + P. sect. Madagascarienses sect. nov. The sections are distinguished by a combination of leaf venation, staminate flower morphology, pistillate flower number, style morphology, fruit type, and seed size. Additionally,
we describe three new species from South America belonging to sect. Penninerviae: Plukenetia brevistyla and Plukenetia megastyla from the Amazon basin and Plukenetia chocoensis from the Chocó Biogeographic Region of Colombia. The new
Amazonian species are morphologically similar to P. brachybotrya but distinguished by their style shape and size. The new Colombian species is morphologically similar to P. penninervia but distinguished by its elongate basilaminar extrafloral nectaries, presence of abaxial laminar
extrafloral nectaries, and longer inflorescences. We also describe a new species from sect. Plukenetia, Plukenetia sylvestris, which is found in central and southern Peru. This species is suggested to be the wild progenitor of the cultivated P. carolis-vegae, differing
by its smaller seeds/fruits and fewer stamens. Molecular data, including a new ETS phylogeny sampling P. brevistyla, support our new taxa as distinct. Keys to the sections and species of Plukenetia are provided and we designate 12 new lectotypes for Plukenetia and Romanoa.
Revising Poeppig´s Collections and Names of Connaraceae from Nova Genera ac Species Plantarum
Authors: Toledo Cassio A. P. , Souza Vinicius Castro , Lucas Eve J.
Published: August 2020

Abstract—During his expedition to South America, Eduard F. Poeppig collected about 17,000 botanical specimens, of which three belong to Connaraceae. These specimens were used to describe more than 500 species in the three volumes of Nova Genera ac Species Plantarum.
In the third volume, Poeppig (1845) described two new species of Connaraceae: Omphalobium rubrum (=Connarus ruber) and Connarus macrophyllus (=Pseudoconnarus macrophyllus). As Poeppig´s descriptions are not accompanied by a clear indication of type specimens,
these two names were afterwards lectotypified. A revision of Poeppig’s collections, descriptions and illustrations indicates that the lectotype of Omphalobium rubrum needs to be corrected, and a second step of lectotypification is required for Connarus macrophyllus. By
correcting a lectotype, a reestablishment is also proposed. Aside from the nomenclatural updates, this work expands the description of the two species published by Poeppig (1845) as well as the reestablished taxon, and illustrates and discusses their taxonomy and distribution.
Taxonomic Revision of Xylophragma (Bignonieae, Bignoniaceae)
Authors: Kaehler Miriam , Lohmann Lúcia G.
Published: August 2020

Abstract—Xylophragma (Tribe Bignonieae, Bignoniaceae) includes seven species of lianas or scandent shrubs. The genus is characterized by leaves 1‐5-foliolate with a simple tendril replacing the terminal leaflet, branched trichomes, calyx usually cuspidate,
pink flowers, and ovary usually lepidote. The genus is distributed through dry forests from Mexico to Paraguay and Southern Brazil. We provide the first comprehensive taxonomic treatment for Xylophragma, including a detailed description of the genus, a key for all species, complete
list of synonyms, descriptions and illustrations for all species, as well as information on the geographic distribution, habitat, phenology, conservation status, and taxonomic comments for all taxa. Overall, we analyzed more than 700 sheets deposited in 13 herbaria, including types for all

A New Species of Randia (Rubiaceae) and the Taxonomic Significance of Foliar Anatomy in the Species of Randia of the Southern Cone of America
Authors: Judkevich Marina D. , Gonzalez Ana M. , Salas Roberto M.
Published: August 2020

Abstract―Randia heteromera is a new species described based on studies of taxonomy and vegetative anatomy (leaf, stipule, and colleters). This species is illustrated and diagnosed in comparison to the other four similar species of Randia in the
Southern Cone of America. The species grows in areas of humid forests, locally known as the humid Chaco in the southern part of its distribution (Argentina and Paraguay), and in seasonal forests in the northern part, in northeast Paraguay and the south of Mato Grosso do Sul in Brazil. We present
a key to distinguish R. heteromera from the other species of the Southern Cone of America. The species was also compared with similar taxa, Randia nitida or R. hebecarpa, occasionally used to identify material from the Southern Cone of America. A distribution map
is provided. The anatomical data studied had a taxonomic value at the species level. In addition, based on the leaf anatomy studies carried out in the present study and in previous studies, three new types of vascular tissue organization in the leaf are described for Rubiaceae.
Jewish Spatial Practices in Barcelona as Claims for Recognition
Authors: Martínez-Ariño Julia
Published: August 2020

In this article, I argue that the spatial practices of the contemporary Jewish organisations in Barcelona’s medieval Jewish neighbourhood represent claims for public recognition. As a small and quite invisible minority within the diverse city population, Jewish groups increasingly claim that their presence in the city should be recognised by political authorities and ordinary citizens alike. They do so through a series of spatial practices around the medieval Jewish neighbourhood, which include (1) heritage production, (2) the renaming of streets and (3) the temporary marking of urban spaces with Jewish symbols. I have grouped these practices under the umbrella concept of ‘place-recovering strategies’ because all of them attempt to ‘recover’ the lost urban environments inhabited by their Jewish predecessors before they were expelled from the Iberian Peninsula in the fourteenth and fifteenth centuries. By recovering I do not mean a mere passive restoring of urban spaces and places but rather a creative process in which historical narratives and myths of the past play a crucial role. Drawing on qualitative fieldwork, I argue that these place-recovering strategies are part of a quest for the visibility, legitimacy and recognition of Jews.
The Demands of Niqabi Women in the Telegram Subaltern Corner Orgullo Niqabi
Authors: Ainz-Galende Alexandra , Rodríguez-Puertas Rubén
Published: August 2020

The present article is about Niqabi women belonging to the private Telegram instant messaging channel Orgullo Niqabi (Spanish for ‘Niqabi Pride’). More specifically, our main objective is to explain what they are demanding, how they articulate their demands through that channel, and why they use it for communicating and to organize their actions. Said demands are mainly linked to their recognition as autonomous and political individuals within the different contexts in which they find themselves. First, our analysis will focus on categorizing their social and political demands for being recognized, not only as Muslims, but also as autonomous, independent, and political beings. Second, we intend to explain how those demands, expressed in the virtual world, are articulated in specific actions in the different societies and social contexts in which these women live. To this end, this article analyzes, following the procedures of the Grounded Theory, the discourses obtained through 27 in depth interviews conducted in the first half of the year 2019. The strength of this research lies in overcoming the difficult access to these women and their discourses as well as in clarifying who they are, what they are demanding from the societies in which they live, how and why they are virtually grouped and the consequences of their virtual grouping in the different societies in which each of them lives.
Inclusive Education for Religious Minorities: The Syriacs in Turkey
Authors: Sakız Halis , Ekinci Abdurrahman , Baş Güldest
Published: August 2020

Expanding the scope of inclusion beyond specific groups such as individuals with disabilities has led to the investigation of school systems’ inclusiveness from the perspective of all students. With this in mind, this research investigated the experiences of students and parents belonging to the ancient Syriac community in Turkey, who inhabited Mesopotamia since the inception of Christianity. Obtaining the views of 43 parents and their 46 children through semi-structured interviews, the school system was investigated at a political, cultural, and practical level in terms of the educational inclusion of Syriac individuals. Overall, student and parent views indicated that: (a) policy-making lacked an approach to reach all students and organize support for diversity; (b) school cultures needed to build a community whereby inclusive values were established; and (c) school practices lacked the organization to target and ensure the learning of all and mobilize resources to achieve this aim. Details of findings are included and discussed. Implications address the importance of building schools that consider the increasingly diverse school populations around the world, with a particular focus on cultural and religious diversity.
Residual analysis in regression mixture model
Authors: Miroshnychenko V. O.
Published: August 2020

We consider data in which each observed subject belongs to one of different subpopulations (components). The true number of component which a subject belongs to is unknown, but the researcher knows the probabilities that a subject belongs to a given component (concentration of the component in the mixture). The concentrations are different for different observations. So the distribution of the observed data is a mixture of components’ distributions with varying concentrations. A set of variables is observed for each subject. Dependence between these variables is described by a nonlinear regression model. The coefficients of this model are different for different components. An estimator is proposed for these regression coefficients estimation based on the least squares and generalized estimating equations. Consistency of this estimator is demonstrated under general assumptions. A mixture of logistic regression models with continuous response is considered as an example. It is shown that the general consistency conditions are satisfied for this model under very mild assumptions. Performance of the estimator is assessed by simulations and applied for sociological data analysis. Q-Q diagrams are built for visual comparison of residuals’ distributions.
Maghetohydrodynamic flows of micro/nano fluids through thin capillaries
Authors: Batyuk L. V. , Kizilova N. M.
Published: August 2020

Steady magnetohydrodynamic (MHD) flows of suspensions of conducting micro/nanoparticles through a thin tube of a circular cross-section in a transverse constant magnetic field driven by a constant pressure drops at the ends of the tube is studied. The governing MHD system of equations for a viscous incompressible micro/nanofluid in the non-induction approximation is solved with the second order velocity slip boundary condition at the wall of the tube. The material parameters of the fluid are considered as nonlinear functions of the particle concentration according to the mixture models of suspensions and electric conductivity theory. The velocity field, pressure, electric current and magnetic field have been computed as series expansions. The influence of two non-dimensional slip coefficients of the flow rate and wall shear stress is studied. Optimal concentrations of the micro/nanoparticles in the suspensions have been computed from the minimum entropy production condition for different slip conditions, material parameters, magnetic fields and flow regimes (Reynolds and Hartmann numbers).

Published: August 2020

The article presents an experimental study aimed at identifying the possibilities of using Board games to develop communication skills in children with autism spectrum disorder (ASD). The study involved 6 children diagnosed with ASD from 4 years 8 months to 8 years. The experiment lasted two and a half months, with each child was conducted about 20 classes (of 2 hours), during which each of the selected games was held 2 times. Two board games were used, corresponding to the level of development of children — “Walker” and “Memory”. Communication skills were evaluated in two directions — the ability to focus on the partner’s actions during the game and ways to address the partner in the game. The analysis of changes in communication skills of each child is presented. In General, the results obtained in the experimental study suggest that board games can act as an effective means of developing communication skills in children with ASD. Through board games, children were able to develop the skills of paying attention to the partner during the game, tracking their actions and waiting for their turn, addressing the partner and answering a question. The results obtained from the presented sample of subjects showed that better dynamics in the development of communication skills were demonstrated by children with initially higher development indicators, regardless of age.
