Electrically conductive and light-weight branched polylactic acid-based carbon nanotube foams
Authors: Liu Wei , Wu Xian , Ou Yangjia , Liu Hao , Zhang Chun 
Published: February 2021

Abstract
In spite of the high electrical conductivity of carbon nanotube (CNT), its tendency to aggregate and expensive cost in fabricating aerogel, foams, and porous materials remains a problem. Therefore, we described a simple and feasible way to design light-weight, high electrically conductive, and cost-efficient polylactic acid (PLA)/CNT foams. The branched PLA (BPLA) resin with excellent melt elasticity and foamability was induced by nucleophilic ring-opening reaction of epoxy-based acrylic/styrene copolymer and PLA. After that, BPLA/CNT composites and foams were prepared by melt-mixing and supercritical carbon dioxide foaming technology, respectively. The thermal, electrical, and foaming properties were studied. The resultant BPLA/CNT foam possessed a low density of 0.174 g/cm3 and high crystallinity of 3.03%. An improvement of the oriented structure of CNT induced by cell growth in BPLA matrix increased the conductivity of the foam up to 3.51 × 104 Ω/m. The proposed foaming materials provided a way for designing and preparing high performance CNT products.
Two-step polyaniline loading in polyelectrolyte complex membranes for improved pseudo-capacitor electrodes
Authors: Luangaramvej Pimchaya , Dubas Stephan Thierry 
Published: February 2021

AbstractA two-step polyaniline (PANI) loading procedure has been developed to produce polyelectrolyte complex composite membranes (CPECs) to be used as supercapacitor electrodes. In the first step, CPECs were prepared by co-precipitation of poly(styrene sulfonate) (PSS) and poly(diallyldimethylammonium chloride) (PDADMAC) mixed with various amounts of PANI as a filler. CPECs were formed by compression molding into 100 micron membranes using NaCl as a plasticizer and characterized for their electrochemical properties. In the second step, the highest capacitance CPEC membranes with 60% PANI loading were further modified and doped by crossflow polymerization of aniline through the composite membranes. By using a two-compartment crossflow reactor containing aniline and ammonium persulfate on each side, the PANI content of the composite membrane was further increased. Cyclic voltammetry showed a doubling in the capacitance of the membranes after the crossflow polymerization. The resulting electrodes were flexible with high capacitance and could be used to improve pseudocapacitor performance.

Abstract
Steam generators are one of the most important components of pressurized-water reactors. This component plays the role of heat transfer and pressure boundary between primary and secondary side fluids. The Once Through Steam Generator (OTSG) is an essential component of the integrated nuclear power system. In this paper, steady-state analysis of primary and secondary fluids in the Integral Economizer Once Through Steam Generator (IEOTSG) have been presented by Single Heated Channel (SHC) and subchannel modelling. Models have been programmed by MATLAB and FORTRAN. First, SHC model has been used for this purpose (changes are considered only in the axial direction in this model). Second, the subchannel approach that considers changes in the axial and also radial directions has been applied. Results have been compared with Babcock and Wilcox (B&W) 19- tube once through steam generator experimental data. Thermal- hydraulic profiles have been presented for steam generator using both of models. Accuracy and simplicity of SHC model and importance of localization of thermal-hydraulic profiles in subchannel approach have been proved.
Fast Track: fast (nearly) automatic formant-tracking using Praat
Authors: Barreda Santiago 
Published: February 2021

Abstract
Fast Track is a formant tracker implemented in Praat that attempts to automatically select the best analysis from a set of candidates. The best track is selected by modeling smooth formant contours across the entirety of the sound, providing the researcher with rich information about static and dynamic formant properties. Fast Track returns text files containing acoustic information (formant frequencies, formant bandwidths, fundamental frequency, etc.) sampled every 2 ms, generates images showing the winning analysis and comparing alternate analyses, and creates log files detailing analysis information for each file. Fast Track features a modular workflow that allows for analysis steps to be run (and re-run) independently as necessary, and is designed to allow for easy correction of tracking errors by allowing the user to override the automatic analysis, or manually edit tracks where necessary. In addition, Fast Track includes tools to aggregate data across tokens, and to easily create vowel plots of mean values or time-varying formant contours. The design and use of Fast Track are outlined using a re-analysis of the Hillenbrand et al. (1995) dataset, which suggests that Fast Track can be very accurate in cases where signal properties allow for reliable formant estimates.
Philosophische Superlative und die Maschine als Symbol
Authors: Schulte Joachim 
Published: February 2021

Abstract
Philosophical Superlatives: Machines as Symbols. – In this paper, my chief aim is to present a close reading of parts of a central sequence of remarks from Wittgenstein’s Philosophical Investigations (191 – 197, cf. Remarks on the Foundations of Mathematics, I, 121 – 130). The apparent theme of this sequence is the idea of a ‘machine as a symbol of its mode of operation’. Obviously, this idea requires a good deal of clarification, and the present paper attempts to elucidate relevant passages which, in their turn, are discussed in the hope of succeeding in spelling out some of the points Wittgenstein has in mind in appealing to the picture of a machine as a symbol of its mode of operation. What will serve as a kind of framework of these elucidations is the notion of a philosophical superlative appealed to by Wittgenstein in a number of remarks that can be seen as particularly characteristic of his later thought. In the course of developing the idea of a philosophical superlative six aspects, or types, of superlatives are distinguished, and the last of these is found to shade into the image of a machine as symbol in a way that allows us to draw on various superlatives in striving to clarify the train of thought underpinning the sequence PI 191 – 197 and related passages.
David Hume & Ludwig Wittgenstein: A Common Approach to Common Sense?
Authors: McDougall Derek 
Published: February 2021

AbstractWith characteristic candour, David Hume is prepared to admit that in ordinary life, but certainly not when reflecting on the nature of perceptual experience, he has no option but to ‘believe in the existence of body’ despite his philosophical reasonings to the contrary. In this instance, his commitment to ‘Common Sense’ has become, as it was not to become for his contemporary Thomas Reid, a direct consequence of participating in a day-to-day existence if nevertheless one which he has no option but to reject when reflecting in the study.Ludwig Wittgenstein, on the other hand, presents us with a picture of what has come to be regarded as a form of Humean ‘phenomenalist language’, private in nature, which, in one of the most famous passages of his later philosophy, he appears to reject via a form ofreductio ad absurdumargument. In what follows, it will be questioned whether his ‘argument’ clearly represents phenomenalist proposals which Hume’s successors, e. g., A.J. Ayer, accepted without question.Ifthere is a misunderstanding here onbothsides, an investigation into its nature must lead to an appreciation of the varying roles attributed by these philosophers to the notion of ‘Common Sense’.
Wittgenstein and Dilthey on Scientism and Method
Authors: Spiegel Thomas J. 
Published: February 2021

Abstract
While Wittgenstein’s work has been extensively investigated in relation to many other important and influential philosophers, there is very little scholarly work that positively investigates the relationship between the work of Wittgenstein and Wilhelm Dilthey. To the contrary, some commentators like Hacker (2001a) suggest that Dilthey’s work (and that of other hermeneuticists) simply pales or is obsolete in comparison to Wittgenstein’s own insights. Against such assessments, this article posits that Wittgenstein’s and Dilthey’s thought most crucially intersects at the related topics of scientism on the one hand and scientific and philosophical method on the other. In reconstructing Dilthey’s conceptions of understanding versus explaining and central points of Wittgenstein’s Remarks on Frazer’s Golden Bough, it becomes apparent that they share a staunch rejection of scientism and use the notion of understanding as a means to prevent methodologies from the natural sciences encroaching onto the human sciences (in Dilthey’s case) and philosophy (in Wittgenstein’s case). Notwithstanding a number of central ways in which these thinkers differ, this article closes by suggesting that there is some evidence according to which Wittgenstein, like Dilthey, can reasonably be understood as championing some central tenets of the hermeneutical tradition.
Effect of milling treatment and additives on the morphology evolution of α-alumina from a commercial boehmite precursor

Published: February 2021

Abstract
Because calcined alpha alumina (α-Al2O3) inherits the morphology characteristic of milled precursors, it is expected that the α-Al2O3 morphology could be improved by controlling the precursor morphology through the use of different milling processes. The microstructure evolution of the boehmite precursor under different milling treatments (planetary ball milling [PBM] and high-energy ball milling [HEBM]) and its influence on the microstructure of as-synthesized α-Al2O3 were investigated. The experimental results indicate that HEBM has a stronger modification effect in crystallinity, particle size and dispersibility of the boehmite precursor than PBM, which is of great importance to inhibit the formation of the typical worm-like structure of α-Al2O3. The microstructure of α-Al2O3 was further improved by the introduction of NH4BF4, NH4F and NH4Cl as additives. In particular, polygon-like α-Al2O3 particles with a size of 0.5 μm and a good dispersibility were prepared by calcination of the precursor with 30 h of HEBM and 20 wt.% NH4BF4.
God’s “Handing Over” as a Divine Curse: A New Reading of the παραδιδόναι Clause in Romans 1:24, 26, 28
Authors: Kim Seon Yong 
Published: February 2021

Abstract
Attempts to unravel the thrice-repeated παραδίδωμι clause in Rom 1:18–32 have been surprisingly few. Against several interpreters who see God’s παραδιδόναι to be basically permissive or abandoning, the present essay seeks to show that reading the passage in light of ancient binding curses, where the verb παραδίδωμι was extensively employed as a terminus technicus, generates a cogent grasp of the text with regard to the tenor and discursive logic of Rom 1:18–32. God’s “handing over” is a divine cursing punishment, and the verb expresses God’s direct involvement in punishment.
Concerning “Everywhere” (1Cor 1,2): Resonances of Cultic Promises?
Authors: Chapa Juan 
Published: February 2021

Abstract
Within the NT, the expression ἐν παντὶ τόπῳ is found only in the Pauline corpus (1Cor 1,2; 2Cor 2,14; 1Thess 1,8; 1Tim 2,8). In 1Cor 1,2, traditionally the phrase has been considered as having an adverbial sense. However, the presence of the specific adverb πανταχοῦ for conveying the same meaning in 4,17 might point to some intentionality in the use of ἐν παντὶ τόπῳ in the initial greetings and not only to preferences of style. The almost total absence of the expression ἐν παντὶ τόπῳ in extrabiblical Greek against a well-attested presence in the OT Greek as a translation of בכל־מקום, suggests that in 1Cor 1,2 the phrase is a Semitism that echoes a cultic OT usage.
Drinking Gall and Vinegar: Psalm 69:22: An Underestimated Intertext in Matt 27:34, 48
Authors: Euler Alida C. 
Published: February 2021

Abstract
The intertextual play with Psalm 69:22 in Matt 27:34, 48 is an important aspect for adequately understanding Matthew’s crucifixion scene. In Matt 27:34 the Roman soldiers offer Jesus “wine mixed with gall”, which is an allusion to Psalm 69:22a. By acting as the praying-self’s opponents, the Roman soldiers are portrayed as the mockers of Psalm 69:22a. In Matt 27:48, the Jewish authorities offer vinegar to the crucified Jesus, which is a clear allusion to Psalm 69:22b. Therefore, the Jewish authorities are portrayed in parallel to the Roman soldiers. Considering that Matthew refers to Psalm 69:22 not in a selective manner, but in the psalm’s context, the parallel between the Roman soldiers and the Jewish authorities extends to the crucial point in Jewish self-conception of being accused of ἀνομία.

AbstractThe effective connectivity of brain networks can be assessed using functional magnetic resonance imaging (fMRI) to quantify the effects of local electrical microstimulation (EM) on distributed neuronal activity. The delivery of EM to specific brain regions, particularly with layer specificity, requires MRI compatible equipment that provides fine control of a stimulating electrode’s position within the brain while minimizing imaging artifacts. To this end, we developed a microdrive made entirely of MRI compatible materials. The microdrive uses an integrated penetration grid to guide electrodes and relies on a microdrilling technique to eliminate the need for large craniotomies, further reducing implant maintenance and image distortions. The penetration grid additionally serves as a built-in MRI marker, providing a visible fiducial reference for estimating probe trajectories. Following the initial implant procedure, these features allow for multiple electrodes to be inserted, removed, and repositioned with minimal effort, using a screw-type actuator. To validate the design of the microdrive, we conducted an EM-coupled fMRI study with a male macaque monkey. The results verified that the microdrive can be used to deliver EM during MRI procedures with minimal imaging artifacts, even within a 7 Tesla (7T) environment. Future applications of the microdrive include neuronal recordings and targeted drug delivery. We provide computer aided design (CAD) templates and a parts list for modifying and fabricating the microdrive for specific research needs. These designs provide a convenient, cost-effective approach to fabricating MRI compatible microdrives for neuroscience research.

Published: February 2021

The prevalence of antibacterial resistance has brought about a growing surge to develop novel approaches to control infectious diseases. Targeting Quorum-sensing (QS) - controlled virulence factors in bacteria has indicated a promising strategy for antipathogenic drugs. Extracts of Philippine Ilongot-Egongot ethnobotanicals Stachytarpeta jamaicensis, Adenanthera intermedia, Mikania micrantha, Hyptis suaveolens, Premna odorata, Cymbopogan winterianus, Phyllanthus urinaria, Dillenia philippinensis, Hydrocotyle vulgaris, Senna alata, Urena lobata, Ceiba pentandra, Ficus sp., Eleusine indica, Diplazium esculentum and Talahib (no known scientific name) were screened using microtiter plate biofilm formation assay for their QS inhibition activity against biofilm formation in Pseudomonas aeruginosa clinical isolate and Pseudomonas aeruginosa PNCM 1335.
Extracts of M. micrantha, H. suaveolens flowers, H. vulgaris, A. intermedia, E. indica leaves, D. esculentum and Talahib have inhibitory effect on P. aeruginosa clinical isolate biofilm formation. Decrease in biofilm formation was shown in extracts of S. jamaicensis., M. micrantha, H. suaveolens, H. vulgaris, U. lobata, C. pentandra, A. intermedia, E. indica, D. esculentum and Talahib. against P. aeruginosa PNCM 1335. RNA extracts of M. micrantha, Talahib and A. intermedia exhibited downregulation of lasR in both test bacteria using qRT-PCR analysis through absolute quantification. The prospects of these ethnobotanicals to inhibit bacterial virulence avoiding antibiotic resistance is presented in this paper.

Neste terceiro número da Revista Holos apresentamos à comunidade científica relevante produção advinda de diversas áreas do conhecimento e diferentes instituições nacionais e internacionais.É válido ressaltar que o mundo vive a maior crise sanitária da história recente com a transmissão da COVID-19, iniciada em novembro de 2019, na cidade de Wuhan na China. Os cientistas vivem o desafio de desenvolver o quanto antes uma vacina para imunizar a população. Enquanto isso não é possível, é reconhecida a eficácia do distanciamento social, recomendado pela Organização Mundial de Saúde/OMS. No Brasil, o total de mortes em decorrência do novo coronavírus chega hoje a 14817.A comunidade científica permanece insistindo na importância do fomento à pesquisa a partir das instituições de fomento nacionais, inclusive com editais que oportunizem o desenvolvimento de todas as áreas, sem hierarquizações.No âmbito do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte/IFRN, a comunidade acadêmica se ressente e resiste à intervenção do Ministério da Educação o qual com a emissão da Portaria n. 405, de 17 de abril de 2020, nomeou um reitor pro tempore, a despeito da eleição ocorrida em 04 de dezembro de 2019, que legitimou o professor José Arnóbio de Araújo como reitor, com resultado homologado pelo Conselho Superior/CONSUP-IFRN. Servidores e estudantes emitiram notas de repúdio à intervenção solicitando a posse imediata ao reitor eleito. Conselhos, Núcleos Centrais Estruturantes e entidades representativas evidenciaram sua indignação às quais somaram-se cartas de apoio da sociedade emitidas por pesquisadores, associações científicas e representantes políticos, os quais rejeitaram o ocorrido enquadrando-o como mais um golpe à democracia, em curso no cenário nacional.Hoje, em mais um #15M, estudantes do Ensino Médio pedem o adiamento do Exame Nacional do Ensino Médio/ENEM, instrumento de avaliação da última etapa da educação básica e de acesso ao ensino superior no país e em algumas instituições estrangeiras. É, portanto, um imperativo ético suspender as inscrições e prorrogar a realização das provas, em um país em que grande parcela da população que participará da avaliação não está frequentando aulas e, quiçá, tem acesso à internet, às tecnologias e seus suportes nesse contexto pandêmico de distanciamento social, o qual amplificou sobremaneira desigualdades sociais estruturantes.Reconhecendo a importância da ciência, da circulação do conhecimento produzido no âmbito da pesquisa, recomendo a visita ao sumário da revista para acesso aos novos artigos publicados.À leitura!

COVO RECICLADO: NOVO MODELO DE ARMADILHA DE PESCA PARA MINIMIZAR OS CONFLITOS ENTRE A LONTRA E OS PESCADORES
Authors: Sousa Rafael Turibio Moraes de , Laurentino Izabela Costa , Corso Gilberto 
Published: February 2021

São várias as espécies de mustelídeos que interagem com populações pesqueiras por todo o mundo, porém, são poucos os estudos que abordam o tema no Brasil. Este é o segundo estudo que enfoca os conflitos entre a Lontra longicaudis (Olfers, 1818 - Ordem: Carnivora; Família: Mustelidae; Subfamília: Lutrinae) com a população pesqueira da APA Bonfim Guaraira, localizada no Estado do Rio Grande do Norte. Foram entrevistadas cinco comunidades que ainda realizam a atividade de pesca com covos artesanais em diferentes municípios. A principal preocupação apontada pelos pescadores foi o interesse da L. longicaudis sobre os covos utilizados para pesca de camarão de rio Macrobrachium sp. (Ordem: Decapoda; Família: Palaemonidae) que estão periodicamente sendo quebrados pela lontra, ademais os covos são confeccionados com materiais oriundos da vegetação in locu. Portanto, o objetivo deste trabalho é apresentar uma solução para melhorar os apetrechos (covos) dos pescadores, através da reciclagem com canos de PVC. O covo produzido foi um sucesso para a pesca artesanal e também gerou subsídios para conservação da L. longicaudis. Apesar da constante perseguição na região, é possível constatar que a grande maioria dos pescadores pensam de maneira diferente, compreendendo que as lontras, assim como eles, também dependem do camarão, do peixe e do rio para sobreviver, neste processo novas ideias foram estimuladas entre os demais pescadores para diminuir este conflito.
