Published: November 2020

This work presents an initial study for hemp fibre produced in Thailand. The study focuses on the application of the filament winding technique in the production of hemp-epoxy composite tubes for a bicycle frame. The motivation is to produce hemp fibre composites from locally available resources in Thailand. For the initial trail, existing bicycle steel tubes were replaced by ±45° filament wound hemp-epoxy composites with thin aluminium inner layers. The mechanical properties of the hemp-epoxy composites were studied according to the ASTM standard. Two static load cases were chosen and considered for a 100 kg cyclist sitting on the saddle and pedalling while standing. The internal forces and moments were calculated for the frame and frame tubes. The stress and buckling analyses were performed using the finite element method for frame tubes considering the above loading cases. The finite element analysis shows that hemp-epoxy composite tubes with ±45° fibre orientation can be used as bicycle frame tubes and meet the design specifications under the considered static load conditions. The filament winding process was accomplished successfully at KMUTNB using an automated desktop filament winding machine.
The Influence of Doctors’ Online Reputation on the Sharing of Outpatient Experiences: Empirical Study
Authors: Wang Yang , Wu Hong , Lei Xueqin , Shen Jingxuan , Feng Zhanchun
Published: November 2020

Background

The internet enables consumers to evaluate products before purchase based on feedback submitted by like-minded individuals. Displaying reviews allows customers to assess comparable experiences and encourages trust, increased sales, and brand positivity. Customers use reviews to inform decision making, whereas organizations use reviews to predict future sales. Prior studies have focused on manufactured products, with little attention being paid to health care services. In particular, whether patients prefer to use websites to discuss doctors’ reputation has so far remained unanswered.

Objective

This study aims to investigate how patient propensity to post treatment experiences changes based on doctors’ online reputation (medical quality and service attitude) in delivering outpatient care services. Further, this study examines the moderating effects of hospitals’ (organizational) online reputation and disease severity.

Methods

Fractional logistic regression was conducted on data collected from 7183 active doctors in a Chinese online health community to obtain empirical results.

Results

Our findings show that patients prefer to share treatment experiences for doctors who have a higher medical quality and service attitude (βservice attitude=.233; P<.001 and βmedical quality=.052; P<.001) and who work in hospitals with a higher online reputation (β=.001; P<.001). Patients are more likely to share experiences of doctors who treat less severe diseases, as opposed to those treating severe diseases (β=−.004; P=.009). In addition, hospitals’ online reputation positively (negatively) moderates the relationship between medical quality (service attitude) and patient propensity to post treatment experiences, whereas the moderating effects of disease severity on doctors’ online reputation are negative.

Conclusions

Our research contributes to both theory and practice by extending the current understanding of the impact of individual reputation on consumer behavior. We investigate the moderating effects of organizational reputation and consumer characteristics in online health communities.
Virtual Reality Cognitive Training Among Individuals With Alcohol Use Disorder Undergoing Residential Treatment: Pilot Randomized Controlled Trial
Authors: Gamito Pedro , Oliveira Jorge , Matias Marcelo , Cunha Elsa , Brito Rodrigo , Lopes Paulo Ferreira , Deus Alberto
Published: November 2020

Background

Alcohol use disorder (AUD) has been associated with diverse physical and mental morbidities. Among the main consequences of chronic and excessive alcohol use are cognitive and executive deficits. Some of these deficits may be reversed in specific cognitive and executive domains with behavioral approaches consisting of cognitive training. The advent of computer-based interventions may leverage these improvements, but randomized controlled trials (RCTs) of digital interactive-based interventions are still scarce.

Objective

The aim of this study is to explore whether a cognitive training approach using VR exercises based on activities of daily living is feasible for improving the cognitive function of patients with AUD undergoing residential treatment, as well as to estimate the effect size for this intervention to power future definitive RCTs.

Methods

This study consisted of a two-arm pilot RCT with a sample of 36 individuals recovering from AUD in a therapeutic community; experimental group participants received a therapist-guided, VR-based cognitive training intervention combined with treatment as usual, and control group participants received treatment as usual without cognitive training. A comprehensive neuropsychological battery of tests was used both at pre- and postassessments, including measurement of global cognition, executive functions, attention, visual memory, and cognitive flexibility.

Results

In order to control for potential effects of global cognition and executive functions at baseline, these domains were controlled for in the statistical analysis for each individual outcome. Results indicate intervention effects on attention in two out of five outcomes and on cognitive flexibility in two out of six outcomes, with effect sizes in significant comparisons being larger for attention than for cognitive flexibility. Patient retention in cognitive training was high, in line with previous studies.

Conclusions

Overall, the data suggest that VR-based cognitive training results in specific contributions to improving attention ability and cognitive flexibility of patients recovering from AUD.

A Smartphone-Based Approach to Screening for Sudden Sensorineural Hearing Loss: Cross-Sectional Validity Study
Authors: Lin Heng-Yu Haley , Chu Yuan-Chia , Lai Ying-Hui , Cheng Hsiu-Lien , Lai Feipei , Cheng Yen-Fu , Liao Wen-Huei
Published: November 2020

Background

Sudden sensorineural hearing loss (SSNHL) is an otologic emergency that warrants urgent management. Pure-tone audiometry remains the gold standard for definitively diagnosing SSNHL. However, in clinical settings such as primary care practices and urgent care facilities, conventional pure-tone audiometry is often unavailable.

Objective

This study aimed to determine the correlation between hearing outcomes measured by conventional pure-tone audiometry and those measured by the proposed smartphone-based Ear Scale app and determine the diagnostic validity of the hearing scale differences between the two ears as obtained by the Ear Scale app for SSNHL.

Methods

This cross-sectional study included a cohort of 88 participants with possible SSNHL who were referred to an otolaryngology clinic or emergency department at a tertiary medical center in Taipei, Taiwan, between January 2018 and June 2019. All participants underwent hearing assessments with conventional pure-tone audiometry and the proposed smartphone-based Ear Scale app consecutively. The gold standard for diagnosing SSNHL was defined as the pure-tone average (PTA) difference between the two ears being ≥30 dB HL. The hearing results measured by the Ear Scale app were presented as 20 stratified hearing scales. The hearing scale difference between the two ears was estimated to detect SSNHL.

Results

The study sample comprised 88 adults with a mean age of 46 years, and 50% (44/88) were females. PTA measured by conventional pure-tone audiometry was strongly correlated with the hearing scale assessed by the Ear Scale app, with a Pearson correlation coefficient of .88 (95% CI .82-.92). The sensitivity of the 5–hearing scale difference (25 dB HL difference) between the impaired ear and the contralateral ear in diagnosing SSNHL was 95.5% (95% CI 87.5%-99.1%), with a specificity of 66.7% (95% CI 43.0%-85.4%).

Conclusions

Our findings suggest that the proposed smartphone-based Ear Scale app can be useful in the evaluation of SSNHL in clinical settings where conventional pure-tone audiometry is not available.

Published: November 2020

BACKGROUND

The novel COVID-19 disease has spread worldwide, resulting in a new pandemic. The Chinese government implemented strong intervention measures in the early stage of the epidemic, including strict travel bans and social distancing policies. Prioritizing the analysis of different contributing factors to outbreak outcomes is important for the precise prevention and control of infectious diseases. We proposed a novel framework for resolving this issue and applied it to data from China.

OBJECTIVE

This study aimed to systematically identify national-level and city-level contributing factors to the control of COVID-19 in China.

METHODS

Daily COVID-19 case data and related multidimensional data, including travel-related, medical, socioeconomic, environmental, and influenza-like illness factors, from 343 cities in China were collected. A correlation analysis and interpretable machine learning algorithm were used to evaluate the quantitative contribution of factors to new cases and COVID-19 growth rates during the epidemic period (ie, January 17 to February 29, 2020).

RESULTS

Many factors correlated with the spread of COVID-19 in China. Travel-related population movement was the main contributing factor for new cases and COVID-19 growth rates in China, and its contributions were as high as 77% and 41%, respectively. There was a clear lag effect for travel-related factors (previous vs current week: new cases, 45% vs 32%; COVID-19 growth rates, 21% vs 20%). Travel from non-Wuhan regions was the single factor with the most significant impact on COVID-19 growth rates (contribution: new cases, 12%; COVID-19 growth rate, 26%), and its contribution could not be ignored. City flow, a measure of outbreak control strength, contributed 16% and 7% to new cases and COVID-19 growth rates, respectively. Socioeconomic factors also played important roles in COVID-19 growth rates in China (contribution, 28%). Other factors, including medical, environmental, and influenza-like illness factors, also contributed to new cases and COVID-19 growth rates in China. Based on our analysis of individual cities, compared to Beijing, population flow from Wuhan and internal flow within Wenzhou were driving factors for increasing the number of new cases in Wenzhou. For Chongqing, the main contributing factor for new cases was population flow from Hubei, beyond Wuhan. The high COVID-19 growth rates in Wenzhou were driven by population-related factors.

CONCLUSIONS

Many factors contributed to the COVID-19 outbreak outcomes in China. The differential effects of various factors, including specific city-level factors, emphasize the importance of precise, targeted strategies for controlling the COVID-19 outbreak and future infectious disease outbreaks.

Authors: Yilma Tesfahun Melese , Inthiran Anushia , Reidpath Daniel , Orimaye Sylvester Olubolu
Published: November 2020

BACKGROUND

Knowledge and skill gaps exist among people from developing and developed countries when locating and using health information. These gaps can be minimized through improved awareness of health information sources.

OBJECTIVE

This research study aims to assess the preferred source of health information used by university students from developing countries.

METHODS

A web-based survey is used as a data collection tool to gather information from a sample of 901 undergraduate students. Binary logistic regression analysis method is used to identify factors associated with sources of health information.

RESULTS

Results reveal that the Internet (82.8%) and television/radio (41.4%) are the primary source of health information among students from Malaysia and Ethiopia, respectively. Higher health literacy level (p = 0.04), higher perceived severity of health problems (p-value = 0.04), and poor perceived health status (p = 0.03) have a positive effect on the choice of the Internet as a primary source of health information. In addition, limited health literacy level (p = 0.03) contributed to the use of television/radio as the primary source of health information.

CONCLUSIONS

The Internet and television or radio are used as the primary source of health information by university students. Health literacy, perceived severity of health problems, and perceived health status are found to affect the use of the Internet as a primary source of health information. Results could help health promoters to pass their health messages via the source that university students prefer.

Les discours de réception du marquis de Marnésia à l’académie de Besançon : un art de l’écart
Authors: Lablanche Julie
Published: November 2020

À la fi n des années 1770, le marquis de Lezay-Marnésia, de vieille noblesse comtoise, est admis à l’académie de Besançon fondée vingt-cinq ans plutôt. Membre associé, puis titulaire du onzième fauteuil, il adresse à ses confrères des discours de réception dans lesquels le respect des normes génériques se caractérise par son instabilité. Le marquis sait à l’évidence aussi bien appliquer les codes que s’en aff ranchir. Commettant, au sein d’un cadre formel contraint, des écarts qui vont de l’entorse sans gravité à la transgression impertinente, il offre avec ses deux discours l’exemple d’une voix singulière, dont on peut faire l’hypothèse qu’elle surprit probablement une majorité de ses confrères bisontins.
Vendre Voltaire : pratiques commerciales, littéraires et politiques dans les prospectus de souscription de Cramer à Beuchot
Authors: Morel Nicolas
Published: November 2020

Cette contribution se donne pour objectif de décrire les relations entre commerce, politique et littérature telles qu’elles se dévoilent au travers des prospectus de vente des OEuvres complètes de Voltaire entre 1750 et 1830. Document qui tire sa forme d’un règlement sur la presse édicté au début du xviiie siècle, et donc lié pour une part à la censure, le prospectus est pourtant un témoignage de l’émancipation progressive du monde de la librairie : il cache en eff et bien souvent des éléments de propagande politique et philosophique. L’étude se base sur un fonds d’archives constitué par Adrien Jean Quentin Beuchot, éditeur de Voltaire sous la Restauration, conservé à la Bibliothèque nationale de France sous la cote n.a.fr. 14300. Il comporte environ soixante prospectus de vente. Le fonds permet ainsi de retracer l’évolution historique de la pratique du prospectus par différents acteurs.
Más allá del comparatismo. Palabra e imagen en el Siglo de Oro: conexiones y límites
Authors: Fernández Rodríguez Natalia
Published: November 2020

El vínculo texto-imagen no es únicamente una cuestión de comparatismo, ni se puede limitar al eco del ut pictura poesis horaciano. Las relaciones intermediales, ampliamente entendidas, son portavoces de estructuras culturales profundas que nos hablan de los modos de ver de toda una época. En concreto, durante el Siglo de Oro, la conexión entre la imagen y la palabra se aprovechó en contextos diversos y con intenciones distintas. Y es precisamente esta versatilidad la que se trata de mostrar en la colección de estudios que conforman este volumen monográfi co.
María en trampantojo. A propósito de las imágenes marianas en la España del siglo XVII
Authors: Vincent-Cassy Cécile
Published: November 2020

En este artículo tratamos de las imágenes marianas de culto local, cuyas tallas son, en muchos casos, «imágenes de vestir», con el cuerpo sin esculpir debajo del vestido y del manto. Estas imágenes se distinguen las unas de las otras por sus atuendos. Tras haber expuesto la complejidad teológica y antropológica de la imagen mariana en España en la época postridentina, exponemos la idea de que estas imágenes, designadas como «retratos», fueron un tema recurrente de las comedias del XVII, constituyendo un auténtico subgénero teatral. La conciencia de la tensión existente en las imágenes entre materialidad y referencialidad, llegó a un grado de sofi sticación muy alto en los llamados «trampantojos a lo divino», como el cuadro que realizó Tomás Yepes de la Virgen de los Desamparados en 1644.
William Ritter et Edmond Bille : danse macabre et contredanse en temps de guerre
Authors: Kaenel Philippe
Published: November 2020

Durant la guerre, alors qu’il est de retour en Suisse, William Ritter fréquente le peintre neuchâtelois installé à Sierre, Edmond Bille. Leurs liens vont se tendre entre 1917 et 1919, autour d’expositions en Suisse et en particulier à La Chaux-de-Fonds. Leurs complicités et leurs dissensions éclatent en 1919, alors que le peintre demande à l’écrivain de rédiger une préface pour son recueil intitulé Une Danse macabre.

« Je ne suis pas écrivain suisse ». William Ritter, la Suisse et sa littérature
Authors: Bussard Denis
Published: November 2020

partir des articles de critique littéraire écrits par Ritter, mais aussi de sa correspondance, et des recensions de ses deux premiers romans, cette contribution se propose de revenir sur la place occupée par le jeune écrivain neuchâtelois au sein du champ littéraire romand de la fin du XIXe siècle. Les modèles symbolistes et décadents choisis par Ritter, de même que le style et l’intrigue d’Ægyptiacque (1891) ou d’Âmes blanches (1893) le placeront à la marge de la littérature produite alors en Suisse – littérature dont il critique le manque d’art et l’inspiration protestante. Tache aveugle de l’histoire de la littérature, l’oeuvre (décadente) du jeune Ritter a peut-être pu, dans une certaine mesure, préparer le terrain aux avant-gardes romandes du début du xxe siècle, ne serait-ce que dans l’émancipation de la morale et l’attention magnifiée à la langue.

En el mundo poético de Garcilaso: desde el "circulus vitiosus" del amante hasta el tiempo cíclico del mito
Authors: Güntert Georges
Published: November 2020

Aunque es cierto que el endecasílabo de Dante y Petrarca fue imitado en la Península ya desde el siglo XV, se debe sin embargo a Garcilaso y Boscán, lectores de Sannazaro, Bembo y Bernardo Tasso, su definitiva aclimatación en el canon poético español. Y es que la novedad de Petrarca, lo que Bernardo Tasso y Herrera llamarán su leggiadria, no había sido entendida antes de 1500. También en el dominio de la sintaxis y el ritmo, los poemas de Garcilaso suponen un paso adelante: los hay, como el soneto XI o la estrofa inicial de la Canción III, sin punto hasta el final, lo que les confiere una estructura unitaria y redonda. Volvemos a encontrar la figura del círculo en la Égloga tercera donde el poeta trata de superar el tiempo a través del mito: inscribir el tiempo de la existencia en el orden cíclico del mito constituye, de hecho, la suprema ambición del poeta toledano.

Keywords: Endecasílabo, Petrarca, leggiadria, Garcilaso, estructuras circulares, tiempo cíclico.
L’absence et le désir dans l’oeuvre de Pascale Kramer
Authors: Fabbri Sandrine
Published: November 2020

Au fil de ses romans, Pascale Kramer creuse les non-dits, sculpte les silences qui séparent inexorablement des êtres qui tentent de s’aimer et de se comprendre. Dépassés par des drames plus grands qu’eux, ils deviennent impuissants à se sauver ou à sauver leurs proches. Comment surmonter la mort d’un enfant, affronter une maladie irréversible, ou un secret de famille qui émerge aussi menaçant qu’un rocher qui pourrait s’écrouler sans que le désir ne s’égare et n’entraîne des protagonistes éperdus dans une ligne de fuite ? Entre auscultation de l’intimité et peinture sociale, l’auteure façonne une comédie humaine contemporaine aux accents profondément mélancoliques.

Keywords : Pascale Kramer, absence, désir, mort, famille
Zone di lettura. Per una didattica dell’esperienza estetica
Authors: Giusti Simone
Published: November 2020

Nussbaum e Todorov, sia pure da posizioni diverse, hanno contribuito a sviluppare un’idea di insegnamento letterario basata sulla lettura simpatetica o immersiva, che consente di cambiare sé stessi e di sviluppare un’attitudine all’incontro con l’altro. Queste idee, che hanno trovato scarsa applicazione in ambito didattico, vengono approfondite e sviluppate alla luce degli studi sull’esperienza estetica e sulla narrazione, nel tentativo di fornire qualche indicazione utile a individuare modelli didattici in grado di valorizzare il ruolo educativo della lettura delle opere letterarie.

Educare al molteplice: la letteratura per l’insegnamento della lingua italiana agli stranieri
Authors: Spera Lucinda
Published: November 2020

L’articolo affronta il tema dell’utilizzo della letteratura nell’insegnamento della lingua italiana, degli scopi e dei valori propri del testo letterario nella classe di lingua sia dal punto di vista di chi forma docenti, sia di chi progetta percorsi didattici indirizzati agli apprendenti. In questo secondo ambito, la riflessione intende rispondere a una duplice sollecitazione didattica: quella di quanti insegnano ad apprendenti stranieri che studiano l’italiano per inserirsi nel mondo del lavoro o perché avvertono il fascino esercitato dalla nostra cultura, ma anche dei docenti della scuola italiana che si trovano a rispondere alle esigenze di ragazzi stranieri inseriti nei percorsi curricolari di formazione scolastica che necessitano di una particolare attenzione sotto il profilo linguistico.

Una lettura de "I promessi sposi": l’esempio del Liceo Cantonale di Porrentruy (Giura)
Authors: Carlucci Alba , Bellavita Domenico
Published: November 2020

Può un romanzo scritto nell’Ottocento e ambientato nel Seicento risultare nei suoi contenuti ancora attuale e quindi rivelarsi interessante agli occhi degli allievi a cui proporlo? È una questione di prospettiva. L’approccio tematico sarà la nostra prospettiva di lettura che, in chiave semiotica, potrà far luce sul concetto di autorità, costruita ed esercitata sull’ambigua alleanza tra potere e finzione. La storia proposta dal Manzoni può essere letta come riflessione e analisi dei segni verbali e non verbali descritti. Parole e gesti che permettono ai personaggi di interagire in un determinato contesto sociale, definendo la propria posizione gerarchica.

¿Crisis del hispanismo? Visiones contra-canónicas y discursos críticos
Authors: Botrel Jean-François , Calvi Maria Vittoria
Published: November 2020

Desde su asentamiento como disciplina académica se ha venido cuestionando el frágil estatuto epistemológico del hispanismo. A partir de los años 1980, se intensificaron las críticas a un hispanismo académico volcado hacia España, estricta o mayoritariamente filológico y clásico, que abrieron paso a visiones contra-canónicas. Con la mirada puesta en este proceso, pero sin desestimar la pujante vitalidad del hispanismo, en el presente artículo se analizan los efectos sobre la disciplina de la crisis de las humanidades y de la globalización. Sin pretensión a establecer un «nuevo paradigma», se contempla la necesidad, para el hispanismo, de tomar conciencia del peligro de una desconexión entre la tradición universitaria y las expectativas de la sociedad. Se aboga por un hispanismo comprometido con su momento histórico y su función crítica ; un hispanismo no hegemónico ni unívoco, sino abierto y plural y, al mismo tiempo, crítico y combativo.

Synthesis and Certification of Lanthanum Oxide Extracted from Monazite Sand
Authors: Samin Samin , Suyanti Suyanti , Sunanti Susanna Tuning , Adi Wisnu Ari
Published: November 2020

Synthesis and certification of lanthanum oxide extracted from monazite sand have been carried out. This research aimed to increase the added value of monazite sand and obtain the lanthanum oxide in-house certified reference material (CRM). Synthesis of lanthanum oxide consists of several stages, namely: monazite sand digestion, rare-earth elements hydroxide [REE(OH)3] precipitation, Ce separation, Nd separation, lanthanum oxalate precipitation, and calcination. Certification of lanthanum oxide was carried out by determining the average concentration of the oxides and its uncertainty from the seven accredited laboratories by the ISO 35-2006 statistical method. Two other minerals in the lanthanum oxide analyzed by the XRD method were cerium hydroxide [Ce(OH)3] and neodymium yttrium oxide fluoride (Nd2Y2O3F16). Lanthanum oxide certified contains ten oxides, with the two highest concentrations of La2O3 (91.662 ± 0.007)% and Nd2O3 (3.949 ± 0.002)%. Lanthanum oxide has met the qualification in-house CRM since it contained water less than 1%, was homogeneous, stable, and certified. La2O3 concentration in the lanthanum oxide in-house CRM from CSAT-BATAN, Indonesia was not significantly different in comparison to that from the Department of Chemical Engineering, Srinakharinwirot University, Thailand. Lanthanum oxide extracted from monazite sand can be used as reference material in determining the lanthanum oxide quality from the pilot plant process.
Metabolic Changes in the Trichomes of Cannabis sativa var. bedrobinol Analyzed by 1H-NMR-Based Metabolomics
Authors: Happyana Nizar , Kayser Oliver
Published: November 2020

Trichomes of Cannabis sativa are the main tissue for synthesizing and storing cannabinoids, the most interesting compounds in this plant. In this report, metabolic changes in the trichomes of C. sativa var. bedrobinol were investigated by 1H-NMR-based metabolomics over the flowering session. Three cannabinoids, including Δ9-tetrahydrocannabinolic acid (THCA), cannabichromenic acid (CBCA), and Δ9-tetrahydrocannabinol (THC), were successfully identified in the chloroform extracts of the Cannabis trichomes. Meanwhile, 20 non-cannabinoid compounds, including sugars, amino acids, and other acidic constituents, were detected in the water extracts. Metabolic changes of the Cannabis trichomes during the monitoring time were successfully revealed using the models of partial least squares discriminant analysis (PLSDA) and 1H-NMR quantitative analysis. Score plots of the PLSDA models classified metabolomes based on the harvest time. Discriminant metabolites for the differentiation were detected in the loading plots of the models. THCA was found as an important discriminant compound in the chloroform extracts, while all quantified water-soluble compounds were detected, contributing to the metabolic changes of the water extracts. The obtained results shed more light on the biosynthesis of metabolites in the Cannabis trichomes over the flowering season.
Application of Titanium-Silica-Graphite Composite Material for Photocatalytic Process of Methylene Blue
Authors: Destiarti Lia , Sasri Risya
Published: November 2020

The use of TiO2 in the slurry system for the photocatalytic process has disadvantages. It causes the resistance of UV transmission because it is cloudy and the difficulty for obtaining the catalyst at the end of the process. Therefore, an attempt to overcome this was conducted by compositing TiO2 on SiO2. Furthermore, carbon material can be used as a support material for TiO2-SiO2, so that the mixed materials can be used as a photocatalyst. The methods for synthesis the material was a sol-gel method by varying the composition of TiO2-SiO2/graphite, which was 1:1; 1:2; and 2:1. The material obtained was characterized by FTIR, DRUV, XRD, and SEM. Photocatalytic activity of the synthesized material was tested in methylene blue solution whereas the quantitative data derived from UV-Vis spectrometry measurement. Photocatalyst activity was carried out by varying the degradation time of 30–180 min. The FTIR spectrum showed that O-H (~3400 cm–1) and C-O (~1100 cm–1) are the major groups in the synthesized materials. The value of bandgap energy (Eg) were 4.15, 4.20, 5.22, and 5.19 eV for TiO2-SiO2, TiO2-SiO2/G (1:1; 1:2; and 2:1) composites, respectively. The XRD pattern of TiO2-SiO2 showed that the highest peaks of 2q were observed at 25.32, 37.71 and 47.91°. Graphite identity appeared at 2q = 59.87°. Micrograph of SEM showed a homogenous dispersion of spherical particles in the materials. Photocatalytic test results showed that TiO2-SiO2/G with a composition of 2:1 has the highest percentage of methylene blue degradation, which reached 94% at 180 min.

Published: November 2020

Imprinted zeolite modified carbon paste (carbon paste-IZ) electrode had been developed as a sensor to analyze blood glucose content by potentiometry. The used zeolite was Lynde Type A (LTA) that synthesized with a mole ratio of Na2O, Al2O3, SiO2 and H2O of 4:1:1.8:270, respectively while non-imprinted zeolite was prepared with a mole ratio of glucose/Si of 0.0306. Glucose was then extracted from the zeolite framework using hot water (80 °C) to produce imprinted zeolite (IZ). The carbon paste-IZ electrode prepared from activated carbon, paraffin pastilles, and IZ with a mass ratio of 5:4:1 showed the best performance. The modified electrode demonstrated the measurement range of 10–4-10–2 M, the Nernst factor of 29.55 mV/decade, the response time less than 120 s, and the detection limit of 5.62 × 10–5 M. Ascorbic acid, uric acid, urea and creatinine did not interfere on the glucose analysis by potentiometry. Comparison test with spectrophotometry showed an accuracy of (90.7 ± 1.4)% (n = 5), while the application of the electrode to analyze five spiked serum samples showed recovery of (92.2 ± 1.3)% (n = 5). The electrode was stable for up to 9 weeks (168 times usage).

In this research, Polyeugenoxy Acetyl Tiophen Methanolate (PEATM)-Au ionic imprinted membrane (IIM) was synthesized. IIM is a PEATM based membrane that has Au(III) ion molds. The PEATM synthesis was analyzed using FTIR spectroscopy, and its relative molecular weight was determined by the viscometry method. To find out the presence of Au(III) templates on IIM, FTIR spectroscopy and SEM-EDX were used. The results of FTIR spectroscopy & SEM-EDX analysis prove the existence of Au(III) metal ion templates at IIM. Through FTIR spectra, it could be seen that the absorption area of the -OH group was widening. In the IIM, the CS group wave number (702.9 cm–1) also shifted to a larger wavenumber (848.68 cm–1), this is likely due to the presence of PEGDE as a crosslinker agent and PVA as a plasticizer on the membrane that interacts with PEATM-Au, which influences the shift of vibrational wavenumber of CS bonds. It was also found that the most effective pH of the feed phase for the transport was at pH 3, and the most optimum transport time was 24 h for IIM and 48 h for NIM. The transport of Au in binary mixture of Au/Cd, Au/Fe, and Au/Pb also proves that the presence of Au(III) ions in IIM makes IIM more selective to Au(III) metal ions than NIM when used for the transport process as it transports Au more than the other metals. These results were as expected by using the HSAB theory as its groundwork.

Carbon nanodots (CNDs) have widely received great attention as a result of favorable optical, electrical, optoelectrical, biocompatible, and non-toxic properties these nanoparticles possess. However, the exploration of nanoparticle from natural raw material was limited. In present work, the carbon dots were produced from catechin isolated from Uncaria gambir through a simple and facile process. Carbon nanodots were further produced by the pyrolysis process of catechin, which allowed it for carbonization. Owing to its unique properties such as photoluminescence with an emission peak at 500 nm (lex = 380 nm), average size diameter about 5 nm and non-toxic; Cat-CNDs were incredibly potential for staining targeted tumor cells. The staining ability by confocal microscopy observations showed their green fluorescence images which meant that the CNDs easily penetrated HeLa cells via endocytosis. The resulting CNDs which were analyzed using some significant techniques approved that the prepared Cat-CNDs were tremendously dispersible and water-soluble, good colloidal stability, excellent biocompatibility, favorable hydrophilicity, high photostability, and non-toxicity.

Mutations in Plasmodium falciparum dihydrofolate reductase (PfDHFR), together with other mutations, hinder malaria elimination in Southeast Asia due to multiple drug resistance. In this article, molecular docking-guided three-dimensional (3D) quantitative structure-activity relationship (QSAR) analysis of 4-aminoquinoline-1,3,5-triazines as inhibitors for the wild-type (WT) PfDHFR to identify the molecular determinants of the inhibitors binding are presented. Compounds 4-aminoquinoline-1,3,5-triazines were reported promising to be developed as the non-resistant drugs. The 3D-QSAR analysis resulted in the best model with the R2 and Q2 values of 0.881 and 0.773, respectively. By correlating the molecular interaction fields (MIFs) of the best model to the docking pose employed to guide the 3D-QSAR analysis, S108 residue of the WT-PfDHFR was unfortunately recognized as one of the molecular determinants. Since the S108 residue is one of the mutation points of the PfDHFR mutants, the subsequent design strategy should modify the morpholine moiety to avoid the interaction with the S108 residue of the WT-PfDHFR.

Published: November 2020

The preparation and characterization of zirconia-supported titania with a zinc dopant had been studied. Zinc-doped titania was grown on the surface of zirconia by the sol-gel method. Various zinc contents and calcination temperatures were applied to investigate the zinc doping effect and crystal structure of the zirconia-titania composite. X-ray diffraction method, Fourier-transform infrared spectroscopy, and UV-Vis reflectance spectroscopy were performed to characterize the composite. The morphology of the composite was observed by using a scanning electron microscope, and its composition was analyzed by using energy dispersive spectroscopy. Among various zinc dopant contents and calcination temperatures investigated, doping with 5% zinc (Zn wt./Ti wt.) at 900 °C calcination shows the best result in response to visible light with a bandgap of 2.87 eV and absorption edge wavelength of 432.61 nm.

Published: November 2020

We attempt to generalize Fibonacci sequence by generating certain number of sequences whose terms are obtained by adding the last two generated terms of the preceding sequence. When we consider the particular case of generating only one sequence we obtain the Fibonacci sequence. Moreover we prove some of the results which can be seen as generalized form of the results which hold for Fibonacci sequence. We also verify the results for the particular case of Fibonacci sequence.

Published: November 2020

A new class of sets called generalized δω−closed sets in topological spaces is introduced and some of their basic properties are investigated. This new class of sets lies between the class of δω−closed and generalized closed sets in (X, τ ). Moreover, we provide several relatively new decompositions of continuity. Several examples are provided to illustrate the behavior of the new sets.
Epigenética: candados y llaves durante la lectura del ADN
Authors: Arceo Martínez Maria Teresa , Valadéz-Graham Viviana , Palomera-Sanchez Zoraya
Published: November 2020

Hasta mediados del siglo pasado, se pensaba que el desarrollo y las características fenotípicas de los organismos dependían únicamente de la información comprendida en los genes. Asimismo, la propensión a enfermedades se atribuía únicamente a mutaciones en la secuencia de ADN de los genes. No obstante, en las últimas décadas se ha puesto especial atención a un nuevo tipo de regulación genómica en la célula: la epigenética. Esta rama de la biología estudia cómo los factores externos de la célula regulan la expresión de los genes sin modificar su secuencia de nucleótidos. Dicha regulación se basa en cambios químicos que pueden actuar como llaves o candados para permitir o bloquear la expresión de un gen. De manera interesante, el ambiente constituye el principal modulador epigenético, ya que, dependiendo de las condiciones a las que esté expuesto el organismo, determinará cuáles genes se abren y cuáles se bloquean. Así, lo que comemos, lo que percibimos y el lugar en donde vivimos, regularán la forma en que se expresan nuestros genes a lo largo de nuestra vida.

Perfil de resistencia antimicrobiana de los aislamientos de Klebsiella pneumoniae en una Unidad de Cuidados Intensivos de Paraguay
Authors: Kennedy-Cuevas Cristel Iona , Estigarribia-Sanabria Gladys Mercedes
Published: November 2020

Introducción: Klebsiella pneumoniae produce enzimas como Betalactamasas de Espectro Extendido (BLEE) y Carbapenemasas. Estas enzimas tienen implicancia en las Unidades de Cuidados Intensivos (UCI), porque posibilitan la supervivencia de especies bacterianas a condiciones desfavorables y por ende, facilitan su permanencia en ambiente intrahospitalario. Existe evidencia de presencia de Klebsiella pneumoniae en UCI, en muestras procedentes de: pacientes, personal de salud, habitación, lavamanos y fórmulas nutricionales. Objetivo: Evaluar el perfil de resistencia de los aislamientos de Klebsiella pneumoniae en una UCI de Paraguay. Material y métodos: Estudio descriptivo observacional, transversal. Se recolectaron 200 muestras (124 fórmulas enterales, 40 ambiente y 36 pacientes). Variables analizadas: origen de muestra, presencia del germen, producción de enzimas y perfil de resistencia. Resultados: Se aisló Klebsiella pneumoniae en 14% de las muestras. Se identificó al germen en: 25% pacientes, 12,9% fórmulas enterales y 7,5% ambiente. Se observó producción de BLEE en 85,7% de las cepas, con perfiles de resistencia idénticos, y producción de carbapenemasas en 14,3% de las cepas, con perfiles de resistencia diferentes. Conclusión: la presencia y los perfiles de resistencia de Klebsiella pneumoniae en las tres clases de muestras estudiadas, sugieren transferencia de genes de resistencia y diseminación del germen en UCI.

Objetivo: Estimar la resistencia del Staphylococcus aureus frente a diferentes antibióticos usados para el manejo ambulatorio de piodermias. Métodos: Se realizaron análisis descriptivos y de tendencias mediante modelos de regresión segmentada. Resultados: La mayor resistencia se presentó a la oxacilina, con mediana de 54,3% (RIQ: 43 - 58,8), seguido de eritromicina con el 20%, (RIQ: 15,4 - 26,5), clindamicina con el 14% (RIQ: 7,9 - 20), gentamicina con el 7,5% (RIQ: 0 -10), trimetoprima/sulfametoxazol (SXT) con el 5,5% (RIQ: 4 - 11), y ciprofloxacina con 2,1% (RIQ: 2 – 8.4). La tendencia de la resistencia del S. aureus a la oxacilina fue creciente con un cambio anual porcentual no significativo de (0,07) (IC 95%: -3,7; 3,9). Para eritromicina, clindamicina, ciprofloxacina, trimetoprima/sulfametoxazol, y gentamicina hubo decrecimiento. Conclusiones: La resistencia del S. aureus a oxacilina fue ligeramente creciente para el periodo 2010 al 2019 y francamente creciente en los últimos 3 años, superando en promedio a lo reportado a nivel país y Latinoamérica. Los antibióticos con menor resistencia fueron ciprofloxacina, SXT, clindamicina para uso sistémico, y ácido fusídico, mupirocina para manejo tópico y descolonización. Es pertinente articular la vigilancia del S. aureus en la atención ambulatoria a la red de vigilancia nacional.

O objetivo deste artigo é apresentar resultados parciais da minha pesquisa acerca da pergunta sobre a natureza do texto filosófico. Parto do problema de o texto filosófico, recentemente, parecer estar restrito à produção acadêmica, obedecendo a uma certa padronização científica, e, com isso, de estar contemplando apenas de modo muito parcial problemas filosóficos em geral, se compreendermos esses como concernentes a uma diversidade e multiplicidade da vida humana, estando presentes em diversos contextos e a partir de diversos lugares de fala, não apenas do homem branco – em geral, o produtor de textos filosóficos acadêmicos. Assim, apresento também como esse problema foi tratado em sala de aula e em uma oficina de extensão.Palavras-chave: Filosofia. Literatura. Texto. Escrita. Gênero.
