When Do Withdrawal Threats Achieve Reform in International Organizations?
Authors: von Borzyskowski Inken , Vabulas Felicity
Published: January 2023

International organizations often come under pressure when states desire their reform. Some states threaten to leave international organizations unless their reform demands are met. But how often is threatening to withdraw associated with states demanding institutional reform? And under what conditions do states’ withdrawal threats actually achieve institutional reform? We argue that withdrawal threats are more likely to result in institutional reform when they (1) are made by powerful states and (2) are limited reform demands rather than calls for broader reform. We examine whether threatening to exit institutions can be a catalyst for institutional reform using an original dataset of withdrawal threats from all international organizations and states since 1980 (N = 130). The analysis supports our argument that withdrawal threats are more likely to lead to reforms when their associated demands are made by powerful states and are limited in scope. Further, we find that less than half of exit threats are linked to reform demands: many states threaten to withdraw due to conflicts with another state or for face-saving purposes, without making reform requests. This contrasts with the conventional understanding that exit threats often represent a backlash against international organizations. Perhaps surprisingly, the dynamics of bargaining over reform suggest that some organizations may emerge more, rather than less, resilient after states threaten to withdraw. We conclude with policy implications for rethinking multilateralism.
Rab21 regulates caveolin‐1‐mediated endocytic trafficking to promote immature neurite pruning

Published: January 2023

Transmembrane proteins are internalized by clathrin‐ and caveolin‐dependent endocytosis. Both pathways converge on early endosomes and are thought to share the small GTPase Rab5 as common regulator. In contrast to this notion, we show here that the clathrin‐ and caveolin‐mediated endocytic pathways are differentially regulated. Rab5 and Rab21 localize to distinct populations of early endosomes in cortical neurons and preferentially regulate clathrin‐ and caveolin‐mediated pathways, respectively, suggesting heterogeneity in the early endosomes, rather than a converging point. Suppression of Rab21, but not Rab5, results in decreased plasma membrane localization and total protein levels of caveolin‐1, which perturbs immature neurite pruning of cortical neurons, an in vivo‐specific step of neuronal maturation. Taken together, our data indicate that clathrin‐ and caveolin‐mediated endocytic pathways run in parallel in early endosomes, which show different molecular regulation and physiological function.
The agreement in accuracy between tomograms, resistograms, and the actual condition of the wood from lime trees harvested from cities
Authors: Mușat Elena C.
Published: January 2023

The internal quality of the wood is one of the main factors affecting the stability of trees, and it has always been of great interest to science and practice. For this reason, the present study aims to compare the results obtained by wood tomograms with those of resistance to drilling and the visual appearance after cutting a slice with a chain-saw, both to evaluate the presence and dimensions of the inside defects, and also to evaluate the irregularities of the wood structure. Round pieces of lime wood harvested from public areas were used for comparison by taking sound tomograms, followed by taking resistograms on two perpendicular directions at the same level. The results showed that internal wood defects are not always the ones that lead to reduced speeds of sound propagation through the wood. In addition, there were instances in which changes in the internal structure of the wood led to improperly colored tomograms, namely the sections characterizing the point of insertion of a thick branch in the trunk, where the tomograms indicated low speeds of sound transfer through the wood in the stem and high speeds in the wood of the branch.

Published: January 2023

The objective of this study was to evaluate the energy potential of Astronium fraxinifolium and Enterolobium gummiferum wood species that grow in the Savannah of Minas Gerais, Brazil, focusing on the production of charcoal. Two discs were removed at 1.30 m from the ground of three trees of each species, and these were later sampled into wedges that were applied in the analysis of wood characteristics and charcoal production in a muffle furnace. The extractives content and basic density of the wood species were determined, and apparent density of charcoal, ash content, heating value, and energy density of both materials were also determined. The woods under study have potential for application in energy production. Emphasis was placed on A. fraxinifolium, which presented wood and charcoal that was denser, had higher energy density, and achieved greater gravimetric yield.
Microcrystalline cellulose isolation – Proposed mechanism: Enhanced coupling
Authors: García Hernández Miguel Ángel , Marure Arturo López , Neira Velázquez María Guadalupe , Mariano Torres Jaime Alfredo , Galvan Adrian Arroyo
Published: January 2023

Cellulose-derived materials are an emergent opportunity for reducing the environmental impact of polymers. Microcrystalline cellulose (MCC) has increasing relevance in many sectors, including pharmacy, food, and reinforcement of polymers, but its application is limited by the low coupling between it and nonpolar polymers and the polar behavior of cellulose derivates. There is not a well-defined model for the isolation of MCC and the factors involved in the length and width, which are elements of high influence on the reinforcement effect of MCC. This study proposes a mechanism for the size reduction of cellulose fibrils isolated through acid hydrolysis and a post-plasma surface modification (PSM) to enhance coupling of the MCC with hydrophobic polymer matrixes. MCC was characterized by FTIR, XRD, and SEM before and after the plasma surface treatment with caprolactone, a biodegradable polymer. There were no changes in the FTIR spectra; however, in XRD the sample exhibited a decrease in intensity. These results suggest that PSM did not change the structure of MCC or chemical composition. However, an increase in the peak temperature of degradation confirmed the surface modification of MCC.
Effect of silica on thermal and mechanical properties of eucalyptus-PVC wood-polymer composites
Authors: Duan Guoyan , He Chunxia , Wang Min , Yang Xingxing , Wang Wei , Wang Yanping
Published: January 2023

Wood plastic composites (WPCs) were prepared by extrusion molding with eucalyptus powder, polyvinyl chloride (PVC), and silica as additives. The mechanical properties, creep behavior, thermal properties, and cross-section microstructure of the composites were analyzed by universal testing machine, thermogravimetric analyzer, and scanning electron microscope. The results show that with the increase of silica content, the tensile strength, bending strength, and impact strength of the WPCs first increased and then decreased. When the silica content was 3.0%, the tensile strength, bending strength, and impact strength of WPC reached the maximum values of 27.5 MPa, 48.8 MPa, and 4.18 KJ·m-2, respectively, which represented increases of 12.6%, 9.4%, and 20.1%, respectively, compared with those without silica. When the stress was 13.4 MPa, the strain value of 3.0% SiO2-eucalyptus/PVC wood plastic composite was 3.3 times that of 4.46 MPa and 1.7 times that of 8.92 MPa. The pyrolysis process of eucalyptus/PVC WPCs showed a similar trend with different silica content.

Harmonization of Aviation Safety and Security Legal Regulation in the European Union: Impact on the Global Convergence of Aviation Law
Authors: Stonkus Saulius
Published: January 2023

This paper deals with civil aviation, which is highly international. Therefore, harmonization of regulation in this area on a global scale is inevitable, which means that aviation law requires an integrated approach. However, only slightly over half of the countries fully comply with the standards issued by the International Civil Aviation Organization for basic international aviation regulation, which poses a serious threat to aviation safety and security. In this respect, the integrative nature of the European Union offers us to look at the Union’s activities in the context of aviation regulation. The aim of this paper is to investigate the impact that the harmonization of civil aviation safety and security regulations in the EU has on the development of global aviation regulations. The paper provides a more detailed analysis of the beginning and further integration of the EU’s internal aviation market and the formation of the Union’s external policy in this area, which has played a key role in harmonizing the legal framework for aviation safety and security. The study revealed the preconditions for the harmonization of aviation safety and security rules in the European Union highlighted the essential features of this process and its impact on the convergence of aviation regulation on a wider scale (beyond the EU).

Published: January 2023

Corrosion is the gradual deterioration of a material through an electro-chemical reaction with its environment. Electrochemical conditions can be created at the film’s base by bacterial film and salt water of marine environment acts as electrolyte according to the marine science. While corroding, dissolved oxygen and other species as well as the metal surfaces pH can be impact electrochemical process on the metal, which in turn affects. To overcome this problem, there are several methods of preventing a material from corroding. Among them, cathodic protection (CP) and coatings are very popular and effective methods for marine corrosion protection that can provide very good protection over a long period of time. Developing anticorrosive additives that are more effective than the conventional inorganic pigments currently used in paint, may have adverse impacts on environment and human health. In this study, we have focused on cathodic protection (CP) and coatings and the combination of them for providing good protection over a long period.

Investigation of the Cross-Sections for the Production of Bromine Isotopes Using Proton-Induced Reactions
Authors: Mezher Hamza A. , Al-Attafi Kadhim , Alkotbe Bashar , Hussein Wisam N.
Published: January 2023

We have considered the production of bromine isotopes by studying the cross-sections of nuclear reactions in the selenium enriched target. This is of importance due to the applications in nuclear medicine and radiation therapy. Eight channels are observed in the production of bromine isotopes: 7634Se(p, 2n) 7535Br, 7734Se(p, 3n) 7535Br, 7634Se(p, n) 7635Br, 7734Se(p, 2n) 7635Br, 7734Se(p, n) 7735Br, 7834Se(p, 2n) 7735Br, 8034Se(p, 4n) 7735Br, and 8034Se(p, n) 8035mBr. The energy of the interacting protons ranging from the threshold is 2.20–84.20 MeV and is calculated by using an activation technique. For the proton-induced production of bromine isotopes from selenium target atoms, the stopping power and the yield have been calculated. The Zeigler formula was applied to investigate the cross-sections and to determine the yield for each reaction over the stopping power range. The total energy of each reaction and the corresponding crosssections are statistically analyzed. These energies are reproduced by the incident proton energy with acceptable errors at 0.01 MeV intervals. One of the most significant results of the current calculations is the stopping power of targets evaluated within the Ziegler and SRIM approaches.

A védőnők szerepe a gyermekkori látásproblémák felismerésében
Authors: Barcsay-Veres Amarilla , Szamosi Anna , Bausz Mária , Nagy Zoltán Zsolt
Published: January 2023

Bevezetés: A 0–18 éves korosztály testi-lelki egészsége
meghatározó a társadalom egészére nézve. A zavartalan látásfejlődés biztosítása
a szülő, a gyermek, a pedagógus, a védőnő és az orvos együttes feladata. Fontos
láncszem a védőnő a családok és az orvosi ellátás között, mert elsőként
észlelhet olyan látószervi eltérést, amelyet majd a gyermekgyógyász, a szemész
vagy a neurológus kezelhet. A csapatmunka nyertese szintén egy közösség, mert a
látás megőrzésén túl esélyt kap a gyermek a megfelelően támogatott testi és
szellemi fejlődésre is. Célkitűzés: Felmérni, hogy napjainkban
a védőnők milyen szemészeti elváltozások kiszűrésére végzik a
látásvizsgálatokat, és milyen eszközök állnak ehhez rendelkezésükre. A tanácsadó
munkát kiegészítik-e oktatóvideókkal, illetve nyitottak-e továbbképzésen való
részvételre. Módszer: Anonim, önkéntes, online kérdőívek
segítségével gyakorló védőnőket kérdeztünk, milyen eltérésekre fókuszálnak,
milyen módszereket használnak. Adatokat gyűjtöttünk arról, hogy beépültek-e a
betegtájékoztató oktatóvideók ajánlásai a védőnők ellátási fegyvertárába,
illetve milyen támogatást tartanának előnyösnek a szemészeti szakma részéről.
Eredmények: Az eredmények szerint a látószervi
szűrővizsgálatok csecsemőkorban a kancsalság, míg iskoláskorban a fénytörési
hibák felismerését célozzák. Általában sztereotesztek és olvasótáblák
rendelkezésre állnak, de pupillalámpák kevésbé. Az oktatóvideókat kevesen
használják, de jelentős érdeklődés mutatkozik posztgraduális szemészeti
továbbképzés iránt. Következtetés: A megkérdezett védőnők
látásszűrő tevékenysége nagy vonalakban tükrözi a legutóbbi szakmai ajánlásokat,
de több területen vannak bizonytalanságok. A védőnői felmérés alapján szabadon
választható, jelenléti és online oktatási anyagot állítottunk össze a védőnők
posztgraduális képzésére, mely pontszerző továbbképzésként nyilvántartásba
került. Orv Hetil. 2023; 164(3): 88–95.

Without making a song and dance about it…
Authors: Williams Katherine
Published: January 2023

This story can be read in three ways. The Story is a fictional day in the life of a female jazz guitarist. The Endnotes tell another story, a referenced timeline of discrimination and sexism against female and minority musicians. You could read The Story by itself. You could read The Endnotes by themselves—taken together, they form a prose story of some of the barriers faced by musicians outside the cishet male narrative. Thirdly, you could refer to each endnote as it appears in the story. This method will be a disjointed reading experience, but perhaps best represents the doublethink necessary from people outside the dominant demography in today’s society.
Wayward lives and beautiful experiments
Authors: Smith Christopher J
Published: January 2023

Saidiya Hartman’s 2021 Wayward Lives, Beautiful Experiments literally re-imagines the experience of young black women in 1910s New York, employing a method Hartman calls ‘critical fabulation’, in which—rather in the form of retconned speculative fiction—she teases out gaps in the archival record. Employing Hartman’s own call-and-response technique of rhetorical questions which spotlight the uncertain answers to questions about minoritized human experience, I ask: ‘How did the “light-skinned chorines” in multi-racial 1930s nightclub and theater culture create spaces of “beautiful experiment” within their day-to-day? How did the “noisy” dance of jazz reinscribe—or subtly subvert—the white racist gaze? What did the chorines think about all this?’ This creative non-fiction essay imagines responses.

Doctrines of Neolithic Religiosity
Authors: Watkins Trevor
Published: January 2023

As a prehistoric archaeologist working on the Neolithic of southwest Asia, I focus on Harvey Whitehouse’s evolutionary theory of the emergence of the doctrinal mode of religiosity in the context of the emergence of “agricultural intensity” and “social inequality” in the Neolithic period, and quite specifically in the latest phase of the occupation of the settlement of Çatalhöyük in central Turkey. I find those difficult phrases ill-defined in the book, and in the author’s published papers on which the book depends. And I contend that the evidence for intensive agricultural production and of institutionalized social inequality is to be found post-Neolithic and associated with the emergence of the first urban societies. I believe that Whitehouse’s idea of the emergence of doctrinal religiosity needs to be argued in the context of the earliest (literate) civilizations of southern Mesopotamia and Egypt.
Cognitively Accessible Words Associated with God as Effective Lexical Primes
Authors: Kitchens Michael B , Lang Isabella M , Petrasic Sydney E , Remper Brian C , Wilson Brittany M
Published: January 2023

Do the words used to prime the concept of God in psychology of religion research studies accurately reflect a mental representation of God? To examine this, two samples completed a free-association task, where they listed 10 words that came to mind when they thought about God (Studies 1a–1b). We found that more than half of the lexical primes used in previous studies were rarely or never produced (< 5 times) in the 2,610 free-association responses. Using a false memory paradigm, Study 2 revealed that the most frequent free-association words produced in Studies 1a and 1b more effectively primed the concept of God than a set of prime words used in previous religious priming studies that were not frequent free-association words in Studies 1a and 1b. This research advances the methodological practices in religious priming research and contributes to an understanding of people’s thoughts about God.
Quantification of dosimetric uncertainties in lung stereotactic body radiation therapy
Authors:   , Huesa Carlos
Published: January 2023

Lung stereotactic body radiation therapy (SBRT) is associated with sources of geometric uncertainties, such as respiratory motion, daily anatomical variations (anatomical baseline shifts between daily and planned position) and the simultaneous movement between the tumor and the multileaf collimator (the so-called interplay effect) during treatment delivery. In this work, several methodologies have been implemented based on deformable image registration to quantify the dosimetric impact of those geometric uncertainties in lung SBRT. These methodologies revealed two main conclusions: First, daily anatomical deviations in patient anatomy generally had a larger dosimetric impact than respiratory motion. Second, the impact of interplay effect could be a concern for highly irregular patient breathing patterns or for long breathing periods, and whether small field size were used for dose conformation purposes. Furthermore, these methodologies developed would be very helpful for clinicians involved in treatment planning and delivery to evaluate treatment robustness against the geometric uncertainties studied in this work.
The Reader and Reading Culture from the Perspective of Student Teachers
Authors:   University of Ostrava, Czech Republic, Vicherková Dana , Malach Josef ,   University of Ostrava, Czech Republic
Published: January 2023

This study aimed at discovering the characteristics of non/traditional readers that can be used to formulate a typology and identify students’ attitudes towards reading for pleasure. It also deals with the social context influencing students’ reading culture. The questionnaire survey was conducted on 381 students at the Faculty of Education, University of Ostrava. The results showed that students who read for more than one hour a day prefer to read books in paper form, including textbooks, over reading electronic books, multimedia texts or playing on computers and consider themselves traditional readers. Non-traditional readers use critical thinking methods to understand texts and prefer a multimedia format for texts when reading for pleasure over playing computer games, reading e-books, and reading paper-based books. The study also points to the growing importance of the evolving multimedia reading culture in the era of the 4.0 Industrial Revolution.

Apart from changing learning and teaching habits, the COVID-19 pandemic has also affected the way parents involve themselves in learning from home. This study explores the challenges parents face when participating in online learning during the COVID-19 pandemic and what ways can be done to encourage students to learn mathematics online. We use multiple case studies to achieve research objectives. This study involved eight mothers of children in elementary school. Six of them are housewives, and the rest are government employees. Semi-structured interviews were used to gather data. Aside from technical constraints such as the availability of internet networks and infrastructure, the findings of this study show that technological literacy and parental involvement in cognitive, emotional, social, and pedagogical aspects are still lacking. We discussed four key findings, including issues with network availability and technological literacy, issues with parents’ routine work and how to accompany their children, parents’ beliefs about mathematics, and parental involvement in cognitive, affective, social, and pedagogical aspects. Finally, the parents’ learning community must be accommodated, developed, and assisted for their involvement to be more effective.

Published: January 2023

In the presented study, researchers consider if the evaluation method impacts early education students’ results and their beliefs about themselves. The results prove significant relation between the method of evaluation and students’ results (with the same questions). The reliability of evaluation depends on the type of diagnosed skills (language or mathematical skills). In an oral examination in the presence of the class, children achieve better results in the linguistic test. Higher scores on mathematical tests were noted in the case of written exams. Research conclusions could be used as a hint for early education teachers and an interesting area for other studies and consideration.

Vinculada ao Projeto "Medicalização em Goiás: investigações críticas na história e contemporaneidade de práticas e discursos biopsicossociais", o presente artigo relata pesquisa referente ao drama da psiquiatrização docente na relação professor-aluno da rede municipal de Goiânia. O absenteísmo-doença de professores da educação básica por razões médicas codificadas com o índice F do CID-10 mostra um contexto de precarização e alienação do trabalho no capitalismo, com impactos na relação social entre docentes e estudantes. Discutimos as características apontadas dessa (e nessa) interação que desvelam a complexidade dialética do drama do adoecimento psíquico e das condições materiais da vivência laboral, com a análise qualitativa de fichas-sínteses elaboradas a partir de prontuários de licenças médicas disponibilizados pela Junta Médica Municipal de Goiânia. Nosso referencial foi a Psicologia Histórico-Cultural tal como interpretada pela Clínica da Atividade de Yves Clot. Consideramos 35 fichas - de 109 analisadas - que se referem à relação professor-aluno no decorrer do processo de psiquiatrização docente. Em seguida, criamos categorias, rotuladas como queixas e desdobramentos, que revelam processos comuns no sofrimento desses docentes. Observamos que a presença de psicopatologias laborais se relaciona à precarização e à desapropriação do real da atividade pelo trabalhador. Consideramos que a doença é um processo socialmente constituído no âmago de um contexto histórico-social dialético, finalizando nossa pesquisa com destaque para a intervenção do coletivo como recurso de enfrentamento à psiquiatrização, bem como subsidiando políticas públicas que visem a enfrentar a precarização laboral.

En noviembre de 2021 la UNESCO aprobó la Recomendación sobre Ciencia Abierta, cuya aplicación hace ineludible incorporar la “cultura abierta” a cualquier política internacional, nacional, regional o institucional vinculada a la información o la investigación. Todo ello, bajo el reconocimiento explícito de la ciencia abierta como requisito para no dejar a nadie atrás en lo que respecta al acceso al conocimiento académico y a los beneficios del progreso científico. Es esta misma convicción la que llevó a la UOC a elaborar en 2018 su propio Plan de Acción de Conocimiento Abierto. El Plan, con horizonte temporal hasta el 2030, es la hoja de ruta y apuesta institucional de la UOC para convertirse en un nodo de conocimiento abierto y global, y así contribuir a la consecución de los Objetivos de Desarrollo Sostenible marcados por la Agenda 2030 de las Naciones Unidas. 

En el quinto año de implementación, y aun con ocho años más de recorrido, en el presente artículo, las personas que han estado a cargo de impulsar el plan comparten los resultados preliminares del proceso y reflexionan sobre de qué manera su puesta en marcha ayuda a la universidad a ser un nodo de conocimiento global, con mayor impacto social. Todo ello, desde la singularidad de ser un plan adoptado por y para una universidad totalmente online.

Introducción: Históricamente, la comunicación científica estuvo dominada por una lógica de marketing en la que oligopolios de editoriales científicas comerciales cobraban altas tarifas para que los investigadores tuvieran acceso a las publicaciones científicas de sus pares. Ante la insostenibilidad de este mercado por parte de la comunidad científica, surgió en un primer momento el Movimiento de Acceso Abierto y, más recientemente y con nuevas aportaciones, la Ciencia Abierta. Frente a este contexto y consciente de las competencias para las que fue instituido, el Instituto Brasileño de Información en Ciencia y Tecnología (Ibict) pasó a crear infraestructuras, proyectos y acciones encaminadas a la consecución de los preceptos defendidos por los citados Movimientos. Objetivo: Indicar y describir las acciones, proyectos e infraestructuras de comunicación científica creadas y coordinadas por Ibict en el contexto del Acceso Abierto y la Ciencia Abierta. Metodología: Este artículo se caracteriza por ser una investigación documental con enfoque cualitativo. Ya que, los análisis se desarrollaron a partir de los más variados tipos de fuentes. Resultados: Los principales resultados muestran que desde principios de la década de 2000, Ibict ha estado trabajando firmemente para construir las infraestructuras necesarias para promover el Acceso Abierto y, más recientemente, la Ciencia Abierta. Este esfuerzo se refleja en la presentación de las 14 acciones, proyectos e infraestructuras creadas y coordinadas por o en colaboración con el Instituto. Conclusiones: Las infraestructuras presentadas denotan el esfuerzo realizado por Ibict para promover la comunicación científica de forma abierta y transparente. Complementarias entre sí, tales infraestructuras son capaces de crear un marco nacional a favor de los pilares del Acceso Abierto y la Ciencia Abierta, destacando a Brasil en el escenario internacional.

Este artículo explora los diferentes efectos de la política de ciencia abierta en el proceso de generación de conocimiento de los investigadores en ciencias básicas: biología, química y física, utilizando un enfoque cualitativo con ocho entrevistas semidirigidas.El principal efecto percibido de la ciencia abierta es el acceso a insumos de la investigación, con el acceso abierto a articulos, los datos de investigación abiertos -especialmente la reutilización de datos y paradatos- y la reutilización de códigos como fuentes principales. Otra cuestión es el aumento de la colaboración con otros colegas en cuanto a la capacidad de colaborar a mayor velocidad y también el fomento del intercambio de ideas, es decir, se trata de un cambio cultural provocado por el intercambio de información. El tiempo dedicado a tareas como la limpieza de datos y codigos y el aumento de las publicaciones depredadoras son dos aspectos desfavorables que se han señalado. Por último, la cuestión de la comunicación científica como parte de la conceptualización de la ciencia abierta también es mencionada por diferentes investigadores, aunque se trata de un tema que queda por explorar.

Current Information on the Diversity of Dinoflagellates of Ukraine
Authors: Bryantseva Yu. V.
Published: January 2023

Presenting current information on the diversity of Dinoflagellata in Ukraine. The use of electron microscopy, as well as molecular genetic research methods over the past 10 years have made it possible to observe significant changes in the taxonomic system of the Miozoa division of the superclass Dinoflagellata. Based on the analysis of 216 literary sources and bringing all the names of dinoflagellates in line with those accepted in the international database AlgaeBase, it was established that the current list of Dinoflagellates of Ukraine includes 368 species (395 infraspecific taxa), belonging to 3 classes, 14 orders, 45 families and 98 genera. The number of species found in Ukraine is an order of magnitude lower than that currently known for Miozoa in the world (3636), and their distribution by order almost coincides and is very uneven: 3 orders include 63% of currently known species in the peace and 71% - in Ukraine. The most diverse orders in Ukraine are Peridiniales (118 species, 32%), Gymnodiniales (82/22%) and Gonyaulacales (60/16%). In comparison with the most complete review by Krakhmalnyi (2011), the species richness of dinoflagellates of Ukraine and their taxonomy underwent significant changes in the last decade. The number of species, orders and genera has increased twice and number of new species and infraspecific taxa has increased by 85 units and one species has been described as new to science. But the species diversity of some dinoflagellates regions of Ukraine remains insufficiently studied, and some of them require additional research. The analysis of the distribution of dinoflagellates in the territorial waters of Ukraine confirmed that most of them inhabit the seas (302 species and infraspecific taxa), which is more then to three times higher than in estuaries (112) and is more to twice those in aquatic complexes on the land (134). Overall, 70% were unique (not found in other ecotopes), while 30% were shared. Naturally, most of them were found in the contact zone between seas and estuaries (14/7%), 4/3% - between the estuaries and land water bodies, 3% were found in the seas and in the land water bodies, and 8/1% were found in all studied ecotopes. This shows the high role of the estuaries, as water contact zones, for the dinoflagellates diversity and the necessity
for their additional studies. Among the species occurring on the land water bodies, the largest number is assigned to the Dnieper-Black Sea, Middle Dnieper and Carpathian-Danube algofloristic subprovinces, due to the presence of water contact zones of different origins and greater study of these areas.

Alga is a diverse and widely distributed microorganism across the globe. An endeavor has been made to study the algae of Toebrongchhu stream, Punakha district, Bhutan including their diversity and distribution pattern. It also assessed the relationship between algae and selected physicochemical parameters of stream water. Stratified systematic sampling was used for the study due to huge differences in altitude and climatic conditions in the study area. The stream was divided into three zones, downstream, mid-stream, and headwater stream along the altitudinal gradient. The algae were collected by scooping, scraping, and scrubbing different moist and submerged substrates from 36 plots along the stream and then preserved in 4% formaldehyde solution. Results present a total of 40 algae taxa including 25 algae identified up to species level, among which 19 are being reported for the first time from Bhutan. Species diversity was higher in downstream altitudinal zone ranging from 1200-1600 m a.s.l. Similarly, the microhabitat pool had higher species diversity. Spearman correlation showed a significant positive correlation of diversity with total dissolved solids, conductivity, salinity, temperature, dissolved oxygen, and pH, and a negative correlation with altitude. Canonical correspondence analysis between algal species and parameters revealed that altitude is the main factor in the distribution of freshwater algae.

Introduction: Inadequate oral hygiene habits such as lack of tooth brushing, use of irrigators, fluoridated toothpastes, and dental floss, as well as the importance of worrying about going to the dentist in the event of any problem in the oral cavity and the continuity of treatment are factors that could increase the risk in patients. Objetive: To determine the association between the level of indifference to dental treatment and the oral hygiene habits of those surveyed adults. Material and Methods: An observational, analytical and cross-sectional study. The level of indifference to dental treatment was evaluated using a translated virtual questionnaire and subsequently internally validated (Cronbach's alpha: 0.91). There were a total of 249 participants, 150 males and 99 females, with a mean age of 30.69 years. For the association of the qualitative variables and the report of the crude and adjusted odds' ratio (OR), a logistic regression was used. We worked with a level of statistical significance of p<0.05 and a confidence interval of 95%. Results: A high level of indifference to dental treatment was obtained in 57.83% of the respondents. Likewise, a statistically significant association was found between indifference to dental treatment and education (p = 0.012). Regarding oral hygiene habits, a statistically significant association was found with flossing (OR = 2.22; 95% CI: 1.10-4.46) (p = 0.025) and brushing before sleeping (OR = 5.26; 95%: 2.26-12-22) (p<0.001). Conclusion: There is a statistically significant association between the level of indifference to dental treatment with oral hygiene habits, flossing and brushing before sleeping. It is advisable to carry out activities in the communities to promote oral health care to reduce levels of indifference to dental treatment.
