Multidimensional graphene nanostructures – synthesis and applications
Authors: Garg Raghav , Roman Daniel San , Cohen-Karni Tzahi 
Published: September 2020

Abstract
Conventional graphene electronics fail to leverage the exceptional surface-area-to-volume ratio of graphene due to the challenges imposed by arranging two-dimensional (2D) nanomaterials in three-dimensional (3D) spaces. Recently, a new topology of graphene, nanowire template 3D fuzzy graphene (NT-3DFG), has been developed to overcome this limitation. We provide an overview of the unique physical and chemical properties of NT-3DFG that are a direct consequence of the material structure and describe NT-3DFG’s promising applications in bioelectronics and energy-related research.

Abstract
One of the main ways we try to understand the COVID-19 pandemic is through time series cross section counts of cases and deaths. Observational studies based on these kinds of data have concrete and well known methodological issues that suggest significant caution for both consumers and produces of COVID-19 knowledge. We briefly enumerate some of these issues in the areas of measurement, inference, and interpretation.
Compatibility of energetic plasticizers with the triblock copolymer of polypropylene glycol-glycidyl azide polymer-polypropylene glycol (PPG-GAP-PPG)

Published: September 2020

Abstract
Glycidyl azide polymer (GAP) is well known as an energetic prepolymer, but its application as a binder in propellants is limited due to its relatively high glass transition temperature and relatively poor mechanical properties. Copolymerization of GAP with polypropylene glycol (PPG) has been shown to improve GAPs properties because of the good thermal and mechanical properties of PPG. In this research we synthesized triblock copolymer of PPG-GAP-PPG and the compatibilities of this copolymer were investigated with energetic plasticizers (20% w/w) n-butyl nitroxyethylnitramine (BuNENA), trimethylolethane trinitrate (TMETN), and butanetriol trinitrate (BTTN) by solubility parameter, differential scanning calorimetry (DSC), rheological analysis, scanning electron microscopy (SEM) and vacuum stability test (VST). The DSC results showed that BuNENA had better compatibility with the triblock copolymer in comparison to TMETN and BTTN. It reduced the T
g of PPG-GAP-PPG from −58 to −63 °C. The rheological analysis was in good agreement with the DSC results obtained for the compatibility of the plasticizers. In the case of the addition of 20% w/w BuNENA, the viscosity of copolymer/plasticizer decreased from 550 to 128 mPa s, indicating appropriate compatibility of plasticizer with the copolymer. SEM images showed a better distribution of BuNENA in the copolymer matrix.

Authors: Youssef Maha A. , Rizk Hoda E. , Attallah Mohamed F. 
Published: September 2020

Abstract
The quantity of liquid organic radioactive wastes produced by the use of radioactive materials in nuclear research facilities is small compared to aqueous radioactive waste, but a special and low-cost treatment method is needed. Here we investigated the adsorption performance of five materials, namely: KU-2 resin, bentonite, charcoal (M&S) and clay adsorbents for the successful removal of 90Sr/90Y from liquid scintillation cocktail waste. The batch adsorption technique (influence of pH, contact time, and temperature), sequential, and column technique were investigated. The efficiency of these adsorbents for the removal of 90Sr/90Y is in this order, resin > bentonite > clay with removal efficiency 90 ± 5.2, 68 ± 3.25, and 65 ± 5.3%, respectively. While charcoal has lower affinity for the sorption processes. Purification of liquid scintillation (LS) cocktail by separation of 90Sr/90Y was successfully carried out by packed column with KU-2 resin. The exhausted loaded column with 90Sr/90Y is successfully regenerated by 25 mL, 1 M HNO3. Characterizations of the original and the purified LS cocktail were carried out using FTIR analysis. The efficiency of the purified liquid scintillation waste (LSW) for the determination of radionuclide is about 62.67 ± 4.8.
La rencontre du sémiotique et du « numérique »: Le rôle d’une modélisation conceptuelle
Authors: Meunier Jean-guy 
Published: September 2020

RésuméDans cet article, nous discuterons de l’intégration du numérique à la sémiotique et proposerons qu’une modélisation conceptuelle puisse offrir un pont de dialogue entre ces deux domaines classiquement cloisonnés. Plus précisément, nous avancerons l’hypothèse que tout projet de recherche qui en appellera à l’informatique soit une démarche scientifique que s’il construit une théorie qui contient, en plus des modèles classiques que sont les modèles formel, computationnel et physique, un modèle conceptuel. Ce lieu, où les chercheur-es conceptualisent les multiples dimensions de leur objet de recherche, sera alors défini en tant que socle d’une relation solide entre la sémiotique et l’informatique. Nous verrons que les différentes définitions du modèle conceptuel convergent vers la thèse soutenant que la connaissance scientifique met en œuvre une instance de conceptualisation qui doit identifier les diverses dimensions du problème en plus de devoir s’exprimer de manière à ce qu’elle soit communicable entre les membres des communautés épistémiques. Nous verrons, enfin, qu’un projet de recherché sémiotique exige la construction d’un tel modèle afin de décrire, généraliser et sélectionner des problèmes et que ce même modèle, conceptuel, sera aussi nécessaire si le ou la sémioticien-ne utilise l’informatique dans le cadre de sa recherche.fr
The role of the laboratory in the diagnosis process in a patient with mildly elevated hCG: a case report
Authors: Alpdemir Mehmet Fatih , Alpdemir Medine , Toka İlknur 
Published: September 2020

Abstract

Objetives
In this case report, the role of the laboratory in the diagnosis process of the patient was treated with methotrexate (Mtx) who was diagnosed with ectopic pregnancy by endometrial biopsy as a result of the exclusion of the possibility of phantom HCG following the patient with βHCG values was discussed.

Case presentation
Our 25-year-old female patient admitted to our hospital obstetrics and gynecology outpatient clinic with irregular menstruation was evaluated with a pre-diagnosis of pregnancy. The hCG level was examined and ultrasonographically evaluated by the clinician. In the initial evaluation of the 25-year-old patient, the HCG concentration of 47 mIU/mL was determined.

Conclusion
Laboratory specialists should be aware of potential problems in hCG measurement. Clinicians and laboratory specialists should always be on consultation to solve clinical problems.
Origins and Evolutionary Patterns of the1.688Satellite DNA Family inDrosophilaPhylogeny
Authors: de Lima Leonardo G , Hanlon Stacey L , Gerton Jennifer L 
Published: September 2020

AbstractSatellite DNAs (satDNAs) are a ubiquitous feature of eukaryotic genomes and are usually the major components of constitutive heterochromatin. The 1.688 satDNA, also known as the 359 bp satellite, is one of the most abundant repetitive sequences in Drosophila melanogaster and has been linked to several different biological functions. We investigated the presence and evolution of the 1.688 satDNA in 16 Drosophila genomes. We find that the 1.688 satDNA family is much more ancient than previously appreciated, being shared among part of the melanogaster group that diverged from a common ancestor ∼27 Mya. We found that the 1.688 satDNA family has two major subfamilies spread throughout Drosophila phylogeny (∼360 bp and ∼190 bp). Phylogenetic analysis of ∼10,000 repeats extracted from 14 of the species revealed that the 1.688 satDNA family is present within heterochromatin and euchromatin. A high number of euchromatic repeats are gene proximal, suggesting the potential for local gene regulation. Notably, heterochromatic copies display concerted evolution and a species-specific pattern, whereas euchromatic repeats display a more typical evolutionary pattern, suggesting that chromatin domains may influence the evolution of these sequences. Overall, our data indicate the 1.688 satDNA as the most perduring satDNA family described in Drosophila phylogeny to date. Our study provides a strong foundation for future work on the functional roles of 1.688 satDNA across many Drosophila species.

Aristolochia clematitis L.
Authors: Bartha Gergely Sámuel , Tóth Gergő , Horváth Péter , Kiss Eszter , Papp Nóra , Kerényi Monika 
Published: September 2020

Introduction
Several Aristolochia species were used as medicinal
herb across Europe and in recent years, their antimicrobial activity has also been
investigated.

Materials and methods
In this study, A. clematitis was selected to evaluate
the aristolochic acids I and II (AA I and AA II) concentrations and the antimicrobial
activity of methanol, hexane, butanol, and ethyl acetate extracts of the root, stem,
leaf, root, and fruit. AA I and AA II contents were measured by a validated
high-performance liquid chromatography–ultraviolet method.

Results
Each fraction of the plant contained AA I and AA II and the root was found to
have the highest contents of AA I (1.09%) and AA II (0.7454%). The minimum inhibitory
concentrations of all extracts were determined by standard microdilution method. The
fruit’s extracts showed the most efficient antimicrobial effect against both
methicillin sensitive and resistant Staphylococcus aureus
strains.

Conclusion
Correlation between the AA I and AA II concentrations and the antimicrobial
effect was not found.
Fenntartó kezelési módok felnőttkori rosszindulatú hematológiai betegségekben
Authors: Udvardy Miklós 
Published: September 2020

Absztrakt:
A fenntartó kezelésmódok elsősorban a gyermekkori akut lymphoid leukaemiában
voltak általánosak, felnőttkorban ritkábbak. Fokozatosan alakultak ki fenntartó
kezelési módok néhány felnőttkori hematológiai betegségben, például néhány
lymphomában – például follicularis lymphoma, köpenysejtes lymphoma –, s az
elmúlt években a myeloma fenntartó kezelése egyre jelentősebb teret nyert. Mára
egyre több onkohematológiai entitás fenntartó kezelése egyre erősödő tendencia,
sokszor a kezdetben csak az indukciós vagy relapsusos esetekben hatékonynak
bizonyuló kis molekulák előtérbe kerülése várható fenntartó készítményként is.
Myelomában a prognózisfüggő fenntartó kezelési mód, mely gyakran akár a
visszaesésig tart, mára minden nemzetközi és komolyabb ajánlás része. Az elmúlt
években megjelentek fenntartó kezelési módok a felnőttkori akut myeloid
leukaemiában is, teljesen új elemként akár transzplantációt követően, akár a
nélkül. Megváltozott az a szemlélet, hogy egy nehéz kemoterápia vagy éppen a
csontvelő-átültetés azért is jó, mert utána kezelésmentessé válhat a betegek
túlnyomó része. Fontos az is, hogy a fenntartó kezelés ne legyen megterhelő, ne
kelljen túl sok időt a kórházban tölteni, minél inkább egyszerű, akár tablettás
formájú lehessen. Vannak tendenciák arra, hogy az indukció, a konszolidáció és a
fenntartó kezelés (például a myeloma egyes esetei) egyre inkább kontinuumot
képezzenek. Orv Hetil. 2020; 161(38): 1623–1628.

Édipo zorro / Oedipus the Fox
Authors: Barbosa Tereza Virginia Ribeiro 
Published: September 2020

Resumo: O artigo se dedica a recortar trechos da peça Οἰδίπους τύρρανος, de Sófocles, aqui traduzida como Édipo zorro, e traduzi-los. O leitmotiv que dirige a seleção é o enfrentamento de Édipo, é de difícil tradução. Sófocles explora a potência dos sentidos lexicais e sintáticos da língua grega ao máximo, a começar pelo título que chegou até nós para a peça – que daria um tratado – se o focalizarmos apenas com o adjetivo (que não é adjetivo, mas substantivo utilizado como adjetivo) τύρρανος. A tradução Édipo Rei é neutralizante; a tradução Édipo Tirano é tendenciosa, capciosa e política demais para um termo que poderia ser traduzido de outras formas, entre as quais a que escolhemos. Por sua vez, o nome próprio Édipo, etimologicamente, suscita variações incríveis e pertinentes se optamos por traduzi-lo. O artigo não pretende discutir filologia nem literatura a fundo, vamos apenas, com uma proposta de tradução, mostrar a pertinência do Édipo para o Brasil em pandemia.Palavras-chave: tragédia; governança; responsabilidade; peste; tradução.Abstract: The article aims at selecting excerpts from Sophocles’ play Oedipus Tyrannus, starred here as Oedipus the fox, and translating them. The leitmotiv that directs the selection is the confrontation of the plague by the ruler. As it is well known, the Sophoclean text, and particularly that which refers to the drama of Oedipus, is difficult to translate. Sophocles uses the power of the lexical and syntactic meanings of the Greek language to the maximum, starting with the title that came to us for the play - which would give a treatise - if we focus on it only with the adjective (which is not an adjective, but a noun used as an adjective) τύρρανος. The Oedipus king translation is neutralizing; the Oedipus tyrant translation is too biased, too captious, and too political for a term that could be translated in other ways such as the one we chose. In turn, the word Oedipus, etymologically, gives rise to incredible and pertinent variations if we choose to translate it. The article does not intend to discuss philology nor literature in depth, I will just go with a translation proposal to show the relevance of Oedipus for Brazil in a pandemic.Keywords: tragedy; governance; responsibility; plague; translation.

La Possession dans la grammaire « pohétique » de Gellu Naum / Possession in Gellu Naum’s “pohetic” grammar
Authors: Galatanu Daniel Lucian 
Published: September 2020

Résumé : Cet article est censé attirer l’attention sur le Surréalisme poétique roumain et sur son représentant le plus important, Gellu Naum qui, ayant assimilé les expériences pré-surréalistes, rimbaldiennes et apollinariennes, donne une réplique vigoureuse au grand Surréalisme français inauguré par Breton, et se lance, à travers les champs magnétiques de la langue roumaine, cette fois-ci, à la recherche d’un anti-langage, ou d’un sur-langage, qui puisse exprimer au mieux sa notion favorite de « pohème » surréel et plus vrai que la réalité. Pour y parvenir, il recourt à la perturbation voulue, ludique et onirique de la grammaire, aux confins de l’absurde infusé de l’humour amer du type ionescien, et avec une forte volonté programmatique de « crétiniser le langage ».Mots clés : Naum ; surréalisme ; crise du langage ; poésie ; littérature roumaine.Abstract: This article aims to draw attention to Romanian Poetic Surrealism and its most important author, Gellu Naum who, having assimilated the pre-surrealist Rimbaud’s and Apollinaire’s experiences, gives a vigorous replay to the great French surrealism inaugurated by Breton, and launches, through the magnetic fields of the Romanian language, this time, in search of an anti-language, or an over-language, which can best express its favorite notion of “poheme” surreal and more real than the reality itself. To achieve this, he resorts to the desired, playful and subconscious disturbance of grammar, on the edge of the absurd infused with the Eugène Ionesco type of bitter humor, and with a strong and programmatic will to “cretinize the language”.Keywords: Naum; surrealism; language crisis; poetry; Romanian literature.
Um olhar sobre a ficção animalista de João Guimarães Rosa: devires e metamorfoses / The Animal Fiction of João Guimarães Rosa at a Glance: Becomings and Metamorphoses
Authors: Neves Márcia Seabra 
Published: September 2020

Resumo: Nas últimas décadas, a inscrição do animal na literatura tem assumindo novos contornos e complexidades, assistindo-se à emergência de uma zooliteratura fundada numa apreensão inédita da animalidade e no trespassamento das fronteiras entre o humano e o não humano. Cada vez mais, os escritores têm multiplicado as tentativas de encenar, por procuração ficcional, novas formas de interação com o animal, seja pela via do compartilhamento de sentidos e afetos, seja pela dos devires e metamorfoses. Neste contexto, a ficção animalista do escritor brasileiro João Guimarães Rosa, um dos maiores animalistas do século XX, constitui um paradigma modelar da figuração literária do animal, visto e escrito, não como simples constructo teórico-ficcional, mas antes como sujeito dotado de uma subjetividade própria e capaz de um olhar interrogante e judicativo sobre o Homem. É o que se tentará demonstrar, neste trabalho, através da leitura crítica de três dos seus contos: “O burrinho pedrês” e “Conversa de bois”, de Sagarana (1946), e “Meu tio o Iauaretê”, de Estas estórias (1969).Palavras-chave: animal; humano; interação; compartilhamento; devir; metamorfose.Abstract: Over the last decades, animal presence in literature has taken on new forms and disclosed new complexities, giving rise toa zooliterature founded upon a renewed insight into animality and the trespassing of the frontiers separating humans and non-humans. Writers have progressively multiplied attempts to enact, through fiction, new forms of interaction with the animal, either through sharing of meaning and affection, or through becoming and metamorphosis. In this context, the Brazilian writer João Guimarães Rosa’s animal fiction, one of the most remarkable 20th century animalist fiction writers, offers a perfect paradigm of the literary figuration of the animal, both seen and written, considered not as a mere theoretical and fictional artifact, but rather as a subject invested with its own ontology and capable of interrogating and judging human behavior. This is the argument we will seek to demonstrate in this article through the critical reading of three of Rosa’s short stories: “O burrinho pedrês” and “Conversa de bois”, included in Sagarana (1946), and “Meu tio o Iauaretê”, from Estas estórias (1969).Keywords: animal; human; interaction; sharing; becomings; metamorphosis.
Comparison of platelet count by manual and automated method
Authors: Jain Dileep Kumar 
Published: September 2020

Background: Since the emergence of dengue fever in the past few years, platelet count has become a routine test in every pathology lab. Common methods are by peripheral blood smears made from blood collected in ethylenediaminetetraacetic acid (EDTA) tubes, by neubaeur chamber, automated method by hematology cell counter.Methods: Blood samples of 460 adult patients and 72 children (<15 years), including indoor and outdoor, between May to August 2019, attending Hind institute of medical sciences, were collected in EDTA tubes. Samples were properly mixed on blood shaker and immediately peripheral blood smears were made and stained with Leishman stain. Platelet count of every sample was done by peripheral blood smear and by Mindray (BC5150) automated cell counter, simultaneously.Results: Results by manual slide method are slightly higher than automated method but significantly not different from automated method.Conclusions: Traditional slide method can also be used if done carefully comparable to automated method especially useful in small labs which can’t afford automated cell counter.
