The World Economic Forum’s (WEF) Strategic Analysis Model outlines areas where the role of the media is important during a pandemic, so these areas may be selected to examine how the Lithuanian media perform their public information function during the COVID-19 pandemic. The study of the content of the Lithuanian media clarifies whether the media take into account the areas that, according to the WEF strategic analysis model, the media has an impact during the COVID-19 outbreak. This should provide new insights into the priorities and communication strategies of the Lithuanian media, especially in the context of the COVID-19 crisis. The aim of the article is to present three Lithuanian online newspapers quantitative and qualitative research and, in the context of the WEF Strategic Analysis model and, based on the data obtained, to assess the role of the Lithuanian media during the COVID-19 pandemic. It has been established that during the pandemic, Lithuanian online media pay sufficient attention to the topic of general governance: good and bad cases of health crisis management are shown to the public. However, during the research it became clear that international news on the topic of global governance dominates in Lithuanian news media: the media pay more attention to events in the international arena, and the challenges of Lithuania‘s internal management account for only a fifth of all information in the researched online newspapers. The article was prepared by Vilnius University journalism master students (2020).

ESTABLISHMENT OF A SYSTEM OF INDICATORS FOR TRANSFORMING THE REGIONAL FARM OF BULGARIA TOWARDS THE BIOECONOMY IN THE CONTEXT OF BIOMASS
Authors: Toteva D. , Popov R. , Marinov P.
Published: November 2021

The bioeconomy includes all sectors and systems that rely on biological resources (animals, plants, micro-organisms and biomass, including organic waste), their functions and principles. The use of new technologies in the national economy is a key moment, which will create opportunities for the production of high - quality products from bioeconomy represented by the different types of activities. In the paper presents some of the basic indicators (socio-economic) applicable in the regional economy of the country, based on the principles and factors specific to each region. The transformation of indicators towards the bioeconomy will give greater opportunities for social and economic prosperity in each region of the country according to its specific characteristics. Biomass is a kind of solar energy conserved in plant and animal organisms. Biomass as a resource includes waste products from animals and human activities. On earth, there is a certain amount of "dead" organic matter that can be used once as a non-renewable resource from organic fuels.
REGULATION AND DEVELOPMENT OF TERRITORIES IN LAND PROPERTIES - REGULATORY ASPECTS AND PROBLEMS
Authors: Velkovska G.
Published: November 2021

The regulation of territories inland properties is a specific technological and legal process, which is carried out through the tools of detailed spatial planning. The detailed development plans regulate streets, neighborhoods, and land properties for construction and for meeting other needs without construction of the respective land properties. The task of the settlement is to prepare the necessary conditions on the territory in order to make possible the realization of the construction itself. In this sense, it can be said that both processes are interrelated, but the leading and necessary role of the process of settlement of land in the land. The unifying moment in both processes is their legal regulation, which takes into account in detail the specifics of the specific territories and on this basis approves the specific parameters of the settlement and construction.
The settlement of a land property determines its boundaries to a street, road or alley (face of the property) and to the neighboring land properties (side and to the bottom of the property). The settlement of each property also determines the type, manner, character, lines and value indicators of construction in the land property. The purpose of the article is to present and analyze some normative aspects and problems related to the regulation and construction of territories in land properties.
The main research method used in the article is normative analysis. On the basis of the performed normative analysis some imperfections of the normative regulation are summarized and as a final result way for overcoming these imperfections are suggested in the conclusion. For the purposes of the analysis, opinions of authors working in this field were also used.
CONDITIONS FOR ESTABLISHING ADMINISTRATIVE-TERRITORIAL UNITS - MUNICIPALITIES IN THE REPUBLIC OF BULGARIA
Authors: Ushatova D.
Published: November 2021

The study aims to show the deficits in the legislation regarding the conditions for establishing municipalities as administrative-territorial units. An experimental methodology for assessing current regulatory conditions for establishing a new municipality in Bulgaria has been proposed, and the results from applying it have been presented. Conclusions were made per group of municipalities. A comparison was drawn between the constitutionally established role of municipalities as the main Administrative Territorial Units, in which local self-government is exercised, and the conditions for establishing a municipality, defined by the Law on the Administrative-Territorial Structure of the Republic of Bulgaria. Based on the results of the study, we have proposed to improve the understanding of the need for real forms in the social and economic sphere, instead of populist promises for a new administrative-territorial division of the country and the future positive effects determined by it.
Identifikasi Amplitudo dan Sudut Kedatangan Sinyal Menggunakan Metode Forward-Backward APES pada Radar Multi-Antena
Authors: Sapriansa Sapriansa , Tahcfulloh Syahfrizal
Published: November 2021

Jenis sistem radar multi-antena ada dua macam yaitu phased-array (PA) dan Multiple-input Multiple-Output (MIMO). Parameter yang digunakan untuk menguji kinerja radar PA dan MIMO ada banyak sekali yang salah satunya adalah estimasi parameter yang berkaitan dengan jumlah target deteksi. Estimasi parameter termasuk di dalamnya yaitu sudut kedatangan sinyal (direction of arrival, DoA) dan amplitudo sinyal pantulan. Penelitian ini mengusulkan perluasan dari pendekatan estimasi parameter yaitu amplitudo and phase estimation (APES) yang dinamakan forward-backward APES (FBAPES). Pendekatan ini memberikan perbaikan resolusi terhadap estimasi amplitudo dan DoA dari sinyal pantulan target radar yang dikomparasikan dengan estimator konvensional seperti least squares (LS). Formulasi dan evaluasi kinerja estimator yang diusulkan akan diuji berdasarkan berbagai faktor seperti besar radar cross section (RCS), resolusi sudut antar dua target, dan jumlah elemen antena di transmitter-receiver (Tx-Rx). Resolusi sudut deteksi yang diperoleh untuk estimator ini lebih baik dari estimator LS, sebagai contoh untuk M = N = 8 maka diperoleh resolusi sudut 3o sedangkan estimator LS sebesar 5,8o. There are two types of multi-antenna radar systems, i.e. the phased-array (PA) and the multiple-input multiple-output (MIMO). There are many parameters used to test the performance of the PA and the MIMO radars, one of which is parameter estimation related to the number of detection targets. Estimated parameters include the angle of arrival of the signal (direction of arrival, DoA) and the amplitude of the reflected signal. This study proposes an extension of the parameter estimation approach, namely amplitude and phase estimation (APES), which is called forward-backward APES (FBAPES). This approach provides improved resolution of the amplitude and DoA estimates of the reflected radar target signal compared to conventional estimators such as least squares (LS). The formulation and evaluation of the performance of the proposed estimator will be carried out based on various factors such as variations in radar cross section (RCS), angular resolution between two targets, and the number of antenna elements in the transmitter-receiver (Tx-Rx). The resolution of the detection angle obtained for this estimator is better than the LS estimator, for example for M = N = 8 then the angle resolution is 3o while the LS estimator is 5.8o.
Pseudomonas aeruginosa significantly increases expression of receptor for advanced glycation endproducts (RAGE) in the septicemia suffering patients
Authors: Kariminik A. , Hosseini F. , Nasiri E.
Published: November 2021

Receptor for Advanced Glycation Endproducts (RAGE) is a cell surface receptor, which recognizes several endogenous and exogenous molecules and subsequently induces expression of several molecules including chemokines. Chemokines are members of the cytokine superfamily and participate in several immune system functions, including cell migration, inflammation, angiogenesis/angiostasis etc. CXC ligand 11 (CXCL11) is an important chemokine which participates in the induction of appropriate immune responses against microbes, including bacteria. The main mechanisms responsible to overcome septicemia are yet to be clarified. Thus, it has been hypothesized that RAGE may participate in induction of CXCL11 in response to the microbial agents. Due to the fact that immune responses play key roles in limitation of infection, it has been proposed that RAGE may inhibit spread of septicemia. Therefore, in this project mRNA levels of RAGE and CXCL11 were explored in the patients suffering from septicemia versus healthy controls. RAGE and CXCL11 expression levels in the 80 subjects, including 40 septicemia patients and 40 healthy controls were explored using Real-Time PCR technique. Accordingly, by using the specific primer against RAGE and CXCL11 in a Rotorgene vehicle the mRNA levels have been determined. The septicemia and the sources of the bacteria in the blood were diagnosed using microbial cultures. The results demonstrated that although mRNA levels for RAGE and CXCL11 did not change in the septicemia patients vs. healthy controls, mRNA levels of RAGE were significantly higher in the patients infected by Pseudomonas aeruginosa compared to those infected by other bacteria, Escherichia coli, Staphylococcus aureus, and Acinetobacter baumannii. RAGE and CXCL11 mRNA levels did not differ among male and female patients. Based on the results it seems that RAGE is a critical receptor against P. aeruginosa during septicemia and more investigations, especially on the RAGE down-stream molecules can clarify its main roles against P. aeruginosa.
Contribuições feministas e questões de gênero nas práticas de saúde da atenção básica do SUS
Authors: Rivera Mariana Fagundes de Almeida , Scarcelli Ianni Regia
Published: November 2021

RESUMO Pretendeu-se refletir sobre a relevância de contribuições feministas como referenciais contrahegemônicos para uma análise crítica de práticas de saúde desenvolvidas em um serviço da atenção básica do Sistema Único de Saúde. Observaram-se ações de profissionais em uma Unidade Básica de Saúde com o objetivo de analisar como se manifestam questões de gênero na atenção básica a partir de perspectiva da psicologia social postulada por Pichon-Rivière em diálogo com produções feministas. A partir de discussão crítica perante visões dicotômicas, como público e privado, e discursos naturalistas, foram identificados três aspectos relevantes: divisão sexual do trabalho, maternidade e ausência paterna; centralidade das práticas de saúde da mulher na reprodução; e binarismo das políticas públicas de saúde. Isso permitiu identificar aspectos importantes acerca das práticas de saúde na atenção básica. Espera-se que este estudo, ao examinar a naturalização e a reprodução de sexismo, racismo e classismo em meio às práticas consideradas, fomente discussões futuras no campo da saúde que caminhem no sentido de uma produção de saberes e práticas comprometidos com a contestação de tais desigualdades.

Published: November 2021

ABSTRACT This study aimed to evaluate possible gender differences among the invited speakers of Brazilian dentistry meetings. The selected meetings (n=15) were held in different states distributed among the five Brazilian regions. The conference programs were manually reviewed, and a database was constructed. Data analysis was performed using descriptive statistics, chi-square and Mann-Whitney tests. A total of 1,195 speakers was identified, 19.7% (n= 235) of which were women. The results of this study provide an overview of the trends of gender disparity in dentistry conferences in Brazil. These findings suggest disseminated gender-discriminatory practices in the promotion of women participation as speakers in such events. This requires more effective approaches to promote gender balance among conference organizing committees and encourage greater visibility and promotion of equity and diversity policies in dental professional societies to ensure more equitable conference programs.

RESUMO No início do ano de 2020, foi realizado no Instituto de Pesquisas Aggeu Magalhães (IAM), unidade da Fundação Oswaldo Cruz (Fiocruz) em Pernambuco, o projeto ‘Meu verão na Fiocruz’, cujo objetivo era permitir o acesso de meninas de escolas públicas do ensino médio aos laboratórios da instituição, para desenvolver curtos projetos de iniciação científica e, adicionalmente, debater sobre o tema da luta feminista para redução da desigualdade de gênero e raça no campo da ciência. Este artigo é um relato de experiência sobre o projeto. A divulgação do projeto foi realizada em oito escolas pelo Observatório Feminista do Nordeste, a inscrição para seleção foi feita por meio do envio de vídeos de um minuto, e a orientação nas pesquisas foi realizada por pesquisadoras de cinco laboratórios do IAM. No total, foram selecionadas 12 meninas que frequentaram os laboratórios de janeiro a fevereiro de 2020. O projeto culminou com a realização de um evento ocorrido no Dia Internacional das Mulheres e Meninas na Ciência. Ao final, foram identificados gargalos que dificultam o acesso de jovens de comunidades periféricas aos programas de iniciação científica, e os caminhos que podem ser seguidos para acelerar esse processo na academia, principalmente no campo da saúde.
Devir-mulher e educação múltipla: cartografias clariceanas
Authors: Costa Gilcilene Dias da , Igreja Fabíola de Fátima
Published: November 2021

Resumo: O texto movimenta cartografias intensivas com a arte literária de Clarice Lispector ao encontro da construção de sentidos para uma educação múltipla. A partir dos percursos rizomáticos das mulheres clariceanas, visa romper com antigas representações que legitimam o ‘ser mulher’ segundo as leis do patriarcado. Estas veredas levam a maquinar o conceito de educação múltipla nos entremeios da filosofia da diferença, com Deleuze e Guattari, e das ressonâncias do pensamento pós-feminista, como Beauvoir e Butler, de modo a tecer as relações entre arte-gênero-educação por conexões rizomáticas e encontros intensivos com as potências feministas do devir-mulher, da escrita clariceana e os devires poético-políticos como possibilidade de fabular espaços de liberdade nas artes de viver e educar.
O Ativismo Católico: Bioética, Direitos Reprodutivos e Gênero
Authors: Sales Lilian
Published: November 2021

Resumo: Neste artigo, acompanharemos o processo de formação do ativismo católico antidireitos sexuais e reprodutivos e antigênero na Igreja Católica, descrevendo alguns de seus momentos e características centrais. Retraçaremos as linhas da política institucional instituída pelo Vaticano que culminaram na explosão militante católica contrária a esses temas. Analisaremos desde a organização da ofensiva doutrinária e acadêmico-científica, marcada pela produção de concepções teológicas e pela sua defesa em termos não doutrinais, mas científicos, jurídicos e filosóficos por experts vinculados à Igreja Católica, até a organização da ofensiva pastoral, centrada na difusão das categorias antidireitos sexuais e reprodutivos e antigênero por meio de todo o aparato institucional da Igreja, desde seu topo até suas bases.
A despatriarcalização de Deus na teologia feminista
Authors: Candiotto Jaci de Fátima Souza
Published: November 2021

Resumo: Neste artigo, analisamos a importância da linguagem para a compreensão do divino e de nós mesmas/os pelo exame das nomeações clássicas que foram identificadas com figuras historicamente patriarcais. Ao fazer este percurso, evocando a estratégica da hermenêutica bíblica feminista, objetivamos desconstruir estas identificações e ressituá-las metaforicamente; privilegiar nomeações que se afastam da normatividade masculina para se referir a Deus. Geralmente, estas imagens estão associadas a um poder patriarcal, onde predomina uma linguagem metafísica e objetiva. Não obstante, quando essas imagens estão associadas a relações de reciprocidade, de inclusão das diferenças e do respeito da pluralidade, a linguagem é predominantemente metafórica. Além de estabelecer o contraste entre essas duas formas de linguagem, nossa hipótese é de que esta última é a mais adequada para se referir a Deus na época atual.

Validation of TRMM data in the geographical regions of Brazil
Authors: Moraes Rafael Brandão Ferreira de , Gonçalves Fábio Veríssimo
Published: November 2021

ABSTRACT The low density of precipitation gauges, the areas of difficult access and the high number of missing values hinder a rapid and effective hydrological monitoring. Thus, the present study aims to statistically validate the precipitation estimates by the data Tropical Rainfall Measuring Mission (TRMM) in relation to the data observed in the Conventional Meteorological Stations (CMSs) in the geographic regions of Brazil. The statistical indicators used were: Correlation Coefficient (r), Mean Absolute Error (MAE), Percentage of Bias (Pbias), T-Test and Mann-Witiney Test. It is concluded that the precipitation data estimated via TRMM are effective and reliable alternatives for hydrological studies in areas that do not have in-situ gauges and/or need to fill missing values in the five regions of the country, especially in the driest months and in larger time scales.

Published: November 2021

ABSTRACT Molecular dynamics simulations were performed to investigate the stability with respect to increasing the simulated temperature from 300 to 2400 K of an isolated cluster composed of 32 titanium atoms. The interatomic interactions were modelled using Gupta potentials as implemented within the classical molecular dynamics simulation software DL_POLY. The radial distribution functions (RDF), diffusion coefficient, and density profiles were examined to study the structural changes as a function of temperature. It was found that the Ti32 nanocluster exhibits temperature structural transition. The icosahedron and pentagonal bi-pyramid structures were found to be the most dominant building block fragments. Deformation of the nanocluster was also measured by diffusion coefficient, and it was found that the Ti32 are mobile above the bulk melting point. The phase transitions from solid to liquid have been identified by a simple jump in the total energy curve, with the predicted melting temperature near the bulk melting point (1941.15 K). As expected, the RDF's and density profile peaks decrease with increasing temperature. Keywords: Molecular dynamics, titanium cluster, radial distribution functions, diffusion coefficient, mean square displacement.
H-FER-Catalyzed Conversion of Methanol to Ethanol and Dimethyl Ether: a First-Principles DFT Study
Authors: Botchway Cecil H. , Tia Richard , Adei Evans , Dzade Nelson Y. , de Leeuw Nora H.
Published: November 2021

ABSTRACT Methanol adsorption and dehydration reactions within zeolites represent important steps in the catalytic conversion process to form long-chain hydrocarbons. Herein, first-principles density functional theory (DFT) is employed in the determination of methanol adsorption and conversion in ferrierite (FER), where we predict the fundamental adsorption geometries and energetics of methanol adsorption. The methanol molecule is shown to physisorb at all explored binding sites, stabilized through hydrogen-bonded interactions with the acid site atOmeth-Hframbond distances ranging from 1.33-1.51 A. We demonstrate that the zeolites' adsorption capability is affected by the silicon/aluminium ratio, with stronger adsorptions predicted in the material with silicon to aluminium fractions of 5 than 8. The adsorption strength is also found to vary depending on the tetrahedral binding site, with the T1O2 site yielding the most stable methanol adsorption structure in the Si/Al ratio = 5(Eads = -22.5 kcal mol-1), whereas the T1O1 site yields the most stable adsorption geometry (Eads = -19.2 kcal mol-1) in the Si/Al ratio = 8. Upon translational and rotational motion, methanol is protonated resulting in the breaking of its C-O bond to form a methoxy species bound to the framework oxygen (O-CH3 distance of 1.37 A), whereas the water molecule is stabilized at the acid site through H-bonding (Owat-H = 2.0 A). Further reaction between the methoxy species and a second methanol molecule results in the formation of ethanol and protonated dimethyl ether, with adsorption energies of -42 and -25 kcal mol-1, respectively. The results in this study provide atomistic insight into the effect of acidity of the FER zeolite on the adsorption and conversion of methanol. Keywords: Zeolites, ferrierite, methanol adsorption, acid sites, density functional theory (DFT).
Teacher burnout and demographic variables as predictors of teachers’ enthusiasm
Authors: KASALAK Gamze , DAĞYAR Miray
Published: November 2021

This study was aimed to investigate the impact of several demographic variables and teacher burnout on teaching enthusiasm. The descriptive correlational model was used. The study sample was comprised of teachers from high schools (9th-12th grades) in Antalya, Turkey during the fall semester of the 2020-2021 academic year. 366 teachers fully completed the questionnaire in 52 high schools. Data were obtained through two scales, namely the Teacher Enthusiasm Scale, and the Maslach Burnout Inventory. Two models were implemented for teaching and subject enthusiasm, separately. Each model included three demographic variables and three sub-dimensions of teacher burnout as predictors of teachers’ teaching and subject enthusiasm. The binary logistic regression analysis was used in the study. The analysis showed that gender and seniority as demographic variables were found to be significant predictors in the teaching enthusiasm model. The average class size was the only variable which was not significantly effective on teaching and subject enthusiasms. Emotional exhaustion and decreasing sense of personal accomplishment were found to be significant predictors for teaching and subject enthusiasm, while emotional exhaustion was the dominant predictor. Also, depersonalization was not a significant predictor of teaching and subject enthusiasm as sub-dimensions of teacher enthusiasm. That the relations’, which can directly and indirectly define the relationship between enthusiasm and burnout in the literature being greatly ignored forms the justification of the current study

The study was aimed to find out the effect of oral reading method based on self-evaluation on fluent reading and reading comprehension of fourth grade elementary students. The search was designed using a mixed method of nested mixed method patterns. In the quantitative dimension of the search from the quasi-experimental models, the unaligned pretest-posttest control grouped pattern was used. In qualitative dimension, interview sand document analysis were conducted. The study group of the research consisted of the fourth grade students at the a Primary School in the province of Nevsehir in Turkey in 2018-2019 academic year. In order to prevent time and cost loss in the determination of the study group, non-selective status sampling method was used. Based on the self-evaluation reading method, the applications were made in the class of their searcher and the other one in the school was determined as the control group. Experimental and control groups were determined (both n = 10). Statistical techniques were used to compare the pre-post-test results of each group. In addition, content analysis method was used to determine the opinions of the experimental group about the application. As to the result it has been observed that reading method based on self-evaluation is effective in improving the correct reading, reading, and reading comprehension skills of the students. It was determined that there was not a significant difference in gender except reading speed in the development of these skills
Social media use of prospective teachers in the post-truth era: Confirmation, trust, critical thinking tendency
Authors: SEL Burcu
Published: November 2021

Critical thinking, trust and confirmation towards social media have become increasingly important in this period called the post-truth era when the reality has become indistinct, is reproduced, and the truth is undermined. The study aimed to examine the prospective teachers' confirmation / trust levels and critical thinking tendencies towards social media in terms of various variables. The research was conducted with the relational survey model. The critical thinking tendency scale and social media confirmation/trust scale were used in the data collection process. In the analysis of the data, Mann Whitney U, Kruskal-Wallis test, and Spearman Brown Rank-Order correlation coefficient were used. It was observed that prospective teachers' critical thinking tendency was at a good level, and their level of confirmation/trust towards social media was at a medium level. It was determined that critical thinking tendency levels did not differ by gender, but by the number of news sources followed on social media and the frequency of reading books. It was seen that their confirmation / trust level towards social media did not differ depending on gender or frequency of reading books, but the level of confirmation varied depending on the number of news sources followed on social media. Additionally, it was determined that there was a low level of positive relationship between the skill regarding critical thinking tendency and confirmation dimension

Kimberley tropical monsoon rainforests of western Australia: perspectives on biological diversity
Authors: Kenneally Kevin F.
Published: November 2021

There are more than 1,500 patches of monsoon rainforest, totaling 7,000 hectares, scattered across 170,000 square km of the tropical Kimberley region of Western Australia. They are small, isolated and embedded within a mosaic of mostly flammable eucalypt savanna woodlands. The status and condition of Kimberley monsoon rainforest biodiversity are assessed based on geographically comprehensive survey data from a total of 100 sites and opportunistic collecting in many others. Monsoon rainforests are rich in species not found in the region’s other vegetation communities. Most rainforests and their associated faunal assemblages are not currently reserved and many of the survey sites were found to be severely disturbed by fire and introduced feral cattle. The disturbance impact of fires, introduced animals and weeds is shown to apply generally across the three major forms of land tenure operating in the Kimberley; namely, Aboriginal land (including Indigenous Protected Areas), Crown land (including pastoral leasehold), and national parks and reserves. The implications of these disturbance factors on the conservation and management practices of monsoon rainforest patches in the region are considered. It is concluded that conservation of patches requires active fire and feral animal management. Equally, however, the long-term genetic viability of these small scattered patches and populations requires effective conservation at the landscape scale. Mounting evidence of the Kimberley as a historical and significant center of refugia warrants action from scientists, governments, conservation agencies, Indigenous landholders as well as local communities to protect and conserve its unique biota and the processes responsible for generating and sustaining it.
Eleocharis elegans (Cyperaceae) new to Florida and a possible native addition to the flora of the United States

Published: November 2021

Eleocharis elegans, a neotropical wetland sedge (Cyperaceae), is reported as new for the United States from a site in Hardee County, Florida. A number of factors suggest this represents a natural occurrence. We speculate that climate change-related factors such as increasingly frequent major storms offer the most logical explanation of its arrival in the United States.
A multiyear qualitative study of an isolated inland population of salt heliotrope (Heliotropium curassavicum var. curassavicum, Boraginaceae) in Arkansas, U.S.A.
Authors: Tumlison Renn , Serviss Brett
Published: November 2021

In Arkansas, Heliotropium curassavicum L. (salt heliotrope, seaside heliotrope) is known from only three locations in which higher salinity allows its existence. We examined one of these sites along Saline Bayou, Clark County, over a period of 10 years to examine the life history of one variety of the species, H. curassavicum L. var. curassavicum (salt heliotrope) in a patch habitat. Seedlings were found only where other plant species did not grow and in areas of soil activity (caused by salinity) much higher than sites upstream of a salt seep. Flood events scoured the streambed habitat, often uprooting established plants, but yearly recruitment was observed from dispersed seeds. Impoundment by beavers (Castor canadensis) more permanently flooded a section of the habitat, resulting in no growth of the plant in newly inundated spaces, but greater numbers of new sprouts were observed along the new banks in the salty portion of the stream. Shading seemed to limit growth of the heliotrope along the stream and under a bridge, as few plants sprouted in those areas and any that did were stunted compared to other specimens growing in full sun.

A reedgrass growing on Steens Mountain, Oregon (U.S.A.), is here described as a species, Calamagrostis utsutsuensis Otting & B.L. Wilson. This plant has been confused with C. purpurascens R. Br., C. koelerioides Vasey, and C. tacomensis K.L. Marr & R.J. Hebda. An identification key is provided to distinguish the Steens Mountain plant from these species and from all other Calamagrostis of the Pacific Northwest and northern Great Basin.
Physalis macrophysa (Solanaceae: Physalinae: subgenus Rydbergis), its taxonomic disposition and relation to other material with large inflated fruiting calyces
Authors: Pyne Milo , Orzell Steve L. , Bridges Edwin L.
Published: November 2021

Examination of the lectotype and isotype material of Physalis macrophysa Rydb. show its compatibility with P. longifolia, having nearly glabrous, ovate-lanceolate to broadly lanceolate leaves, and the presence of short, simple antrorse hairs on the petioles and pedicels. Other than its large inflated fruiting calyces (3.0–4.0 cm × 2.5–3.0 cm), it has little in common morphologically with another large inflated calyced Physalis macrosperma which is endemic to deep sands from a portion of the West Gulf Coastal Plain of the United States. Instead, P. longifolia has stems and pedicles that are either nearly glabrous or with antrorse, appressed, non-glandular hair and ovate-lanceolate leaves versus short glandular and non-glandular, spreading, upright hair and cordate to truncate leaves in the aforementioned Physalis macrosperma. We agree with previous authors that P. macrophysa Rydb., if meriting taxonomic status, should be treated as P. longifolia var. subglabrata (Mack. & Bush) Cronquist forma macrophysa (Rydb.) Steyermark or, alternatively, it may simply represent variation within P. longifolia not deserving of any taxonomic status.
Nomenclature and redescription of the Jaumave Valley (Mexico) populations of Astrophytum myriostigma (Cactaceae)
Authors: Montanucci Richard R. , Kleszewski Klaus-Peter
Published: November 2021

Astrophytum myriostigma Lem. subsp. quadricostatum (H. Moller) K. Kayser and Astrophytum myriostigma Lem. subsp. tamaulipense K. Kayser are both validly published names, but the subspecific epithet quadricostatum has priority (published in 1927) over tamaulipense (published in 1932) and is, therefore, the correct name for the Jaumave Valley Bishop’s Cap. The Jaumave Valley populations have differentiated from subsp. myriostigma in several morphological characters. Both taxa have distinctly different stem morphology as seedlings but become similar in early maturity, although older Jaumave plants are usually slightly taller and more slender than subsp. myriostigma. As seedlings several years of age, the Jaumave plants have a slender, elongate stem resembling that of subsp. tulense K. Kayser, but they differ from both subsp. myriostigma and subsp. tulense in having black spines up to 4 mm long. The flowers of subsp. quadricostatum are slightly smaller and have fewer tepal rows than those of subsp. myriostigma. The smallest flowers, with one or two tepal rows, are typically found in subsp. tulense. Further comparisons among the three taxa must await the completion of studies now in progress.
Multivariate morphometric analysis of taxonomic relationships in Eleocharis tenuis (Cyperaceae)
Authors: Gibbons Lane D. , McMullen Conley K.
Published: November 2021

Morphology of Eleocharis tenuis is traditionally recognized as being highly variable and delimited only to the level of variety. However, novel morphometric data indicate that the varieties of E. tenuis are unique and well delimited by four of ten characters examined in this study. Furthermore, these unique morphological entities are supported by correlating cytological data. Herein, we treat E. tenuis var. verrucosa at the rank of species, as E. verrucosa, to reflect the evolutionary significance of this entity. We also provide a key to distinguish E. verrucosa from the remaining varieties of E. tenuis.

A floristic inventory of the Holmes Avenue Tract (Highlands County), Florida, U.S.A.
Authors: Wilder George J. , McCollom Jean M. , Bissett Nancy J.
Published: November 2021

Documented presently as growing wild within the Holmes Avenue Tract (Highlands Co., Florida, U.S.A) are individuals of 106 families, 282 genera, 464 species, and 478 infrageneric taxa of vascular plants. Of the 478 infrageneric taxa documented presently, 386 (80.8%) are native and 36 (7.5%) are endemic to Florida. Herein, seven main kinds of habitats are recognized for the study area, and individual taxa inhabit one or more of those habitats. Twenty-four presently reported infrageneric taxa are listed as Endangered (18 taxa) or Threatened (6 taxa) in Florida. Based on Wunderlin et al. (2019), 36 species plus one variety are newly reported for Highlands County.
Floristic survey of vascular plants in Crawford and Cherokee Counties in southeastern Kansas, U.S.A.
Authors: Young Pryer Samantha , Snow Neil , Kartesz John
Published: November 2021

This study documented the vascular flora of Crawford and Cherokee counties in southeastern Kansas. Each county experienced limited collecting in recent decades. A Pittsburg State University (PSU) student (Earl Sam Gibson) summarized the flora for Crawford County in 1963, but an extensive survey had never been done for Cherokee County. Fieldwork for the present study occurred mostly in 2014 and 2015. Based on approximately 6450 newly collected specimens, vouchers at PSU (including those of Gibson), and taxa documented by Biota of North America (BONAP) (Kartesz 2019), a total of 1420 unique taxa (species, subspecies and varieties) are reported for both counties combined, including 148 families, 591 genera, and 111 non-nominal infraspecific taxa. Of these, 1177 (82.9%) are native and 243 (17.1%) are non-native. A total of 44 state and 233 county records are documented. Included were 15 species of hybrid origin and 22 that are adventive from other parts of North America. Significant among the state records is the first published adventive occurrence of the genus Pinus in Kansas. Cherokee County has 1281 taxa (including 81 county records), whereas Crawford County includes 1139 taxa (and 152 county records). An important finding of our study, along with those of other recent floristic studies, is that vascular plant distributions at the state and county levels in the U.S.A. are less well documented than probably assumed. This is especially true for weedy taxa occurring in highly agricultural and industrial counties, as well as taxa with small, inconspicuous flowers and inflorescences, and counties relatively distant from universities. Undocumented occurrences of such taxa may adversely affect interpretations and distribution patterns of abundance, as for example when modeling plant distributions.

Heat transfer enhancement using different types of turbulators on the heat exchangers
Authors: ÇELIK Hamdi Selçuk , ERBAY L. Berrin
Published: November 2021

Energy-saving and heat transfer enhancement considerations are more crucial due to nearly running out energy resources and ensuring the sustainability of nature. The heat exchangers are one of the main components and directly affect the thermal efficiency of the systems. To enhance the heat transfer rate, the fin and plate structure is widely used. Various vortex generators may be involved generally on the surface of fins, like ribs, baffles, delta winglets, and perforations. Turbulators make the heat transfer performance better significantly but increase the friction of the fluid on the contacting surfaces and cause the pressure drop-down which depends on thermal properties of the fluid characteristics. This paper presents general protrusion vortex generators overview to heat transfer augmentation with pressure loss as an extensive literature review. The correlations are derived in terms of some parameters of turbulators like; angle, pitch, shape and combinations of an array. The target of this study is consolidating the verified outputs of the literature and support the increasing thermal performance of the heat exchangers. In conclusion, two tables are made for the first time and summarizing the crucial features of solid, perforated baffles/blockages and winglet turbulators, mentioned in the literature are presented. Obstacles such as winglets and vortex generators are used commonly to increase the heat transfer rate per unit volume for finned to tube exchangers with various types. In order to augment the heat transfer, the design parameters of important consideration are attack of angles, height and array structure in both laminar and turbulated fluid characteristics. Involving perforation forms on the surface may be used for winglets with variable angles both decrease the pressure loss and increase the heat transfer performance.
Numerical comparison study on heat transfer enhancement of different cross-section wire coils insert with varying pitches in a duct
Authors: GÖKSU Taha Tuna , YILMAZ Fuat
Published: November 2021

Heat transfer enhancement (HTE) efforts spent during the last half-century have become one of the most important working areas of researchers from both academia and industry. One of the most popular passive methods, with regard to the price-performance ratio, is to place wire coils in a pipe or duct. In this study, the heat and pressure drop characteristics of diamond, triangular, and circular cross-sectional wire coils (DWC, TWC, and CWC) in a square duct were investigated by using the FLUENT program. In addition to the cross-section examination, the thermo-hydraulic behavior of three different pitches (p = 54, 72, and 90 mm) for the specified geometries were also investigated. The Reynolds number was between 4387 and 18,415. The square duct was 1.25 m in length, and was 18 mm in diameter. The results showed that the Nusselt number of CWC, TWC, and DWC were higher than that of a smooth pipe within 38–88%, 37–93%, and 38–98% range, respectively. The friction of CWC, TWC, and DWC was observed to be higher than that of a plain tube within a range of 87–278%, 82–266%, and 107–366%, respectively. The TWC with 90 mm pitch showed the highest heat transfer performance evaluation criteria (PEC) with a performance coefficient of 1.3 at Reynolds number of 4504, whereas the DWC with 54 mm pitch was observed to show the lowest PEC. Thus, the as-obtained PEC, which is 30% higher than that of a plain tube, indicates the prominence and effectiveness of the numerical study in increasing the heat transfer.
