La temporalidad en el cómic
Authors: Peñalba García Mercedes
Published: July 2020

En este artículo se examina la noción de temporalidad en el lenguaje visual del cómic: en las viñetas de prensa, en las transiciones de viñetas adyacentes (clausura y mapa temporal de McCloud) y en las relaciones semánticas entre viñetas consecutivas de una misma página o de páginas distantes con gran similitud gráfica (concepto de «artrología» de Groensteen). El análisis de casos prácticos pone en tela de juicio las tesis de McCloud y de Groensteen, basadas en la linealidad temporal, como modelo para la comprensión de imágenes yuxtapuestas (secuencialidad), cuando se priman en la página relaciones espaciales entre viñetas sin dependencia temporal.This article examines the notion of temporality in the visual language used in comics: in individual panels (i.e. editorial cartoons), in panel-to-panel transitions (McCloud’s closure and temporal mapping), and in semantic relations between panels on a page or in distant relationships of graphic similarity across pages (Groensteen’s arthrology). Through an exploration of selected examples, we argue that McCloud’s approach, like Groensteen’s, is rendered insufficient for explaining the progression of moments of time that guide the comprehension of sequential images when non-temporal relationships between panels (i.e. the spatial qualities of the panels’ relations) become highlighted.

Herejía, confesión e inquisición en el gobierno eclesiástico medieval. La dimensión política del juicio pastoral
Authors: Catalina Gallego Cristina
Published: July 2020

El artículo pretende evidenciar la dimensión política –en un sentido amplio– de la confesión y la inquisición en su emergencia como procedimientos para sentenciar el pecado oculto. Lo hace al insertar ambos en las formas duales, pastorales y jurídicas, que desarrolla el gobierno eclesiástico plenomedieval para la condena de la inobediencia a la nueva ortodoxia y ortopraxis romana. A este respecto, los dispositivos confesional e inquisitorial se comprenden en relación con la emergencia de lo herético como impugnación obstinada al gobierno romano –en la tensión entre el gobierno de sí y de los otros–.
Lo mejor de uno mismo y las alternativas epistémicas
Authors: Grimaltos Mascarós Tobies
Published: July 2020

El Principio de Posibilidades Alternativas (PPA) supone un problema para las posiciones compatibilistas respecto de la responsabilidad moral. Desde que Harry Frankfurt diseñara uno, los (supuestos) contraejemplos al PPA se conocen como casos Frankfurt. Una de las mejores líneas de defensa de este principio frente a los nuevos casos Frankfurt es la que se ofrece en Moya (2011 y 2014). En este artículo me propongo mostrar que su estrategia no es satisfactoria y, al mismo tiempo, argumentar que para la atribución de responsabilidad moral por una acción es suficiente (ceteris paribus) con que existan alternativas epistémicas.
M. Foucault: poder, perspectiva y verdad en Edipo Rey de Sófocles
Authors: Panea Márquez Jose Manuel
Published: July 2020

Nos proponemos en este artículo analizar la lectura foucaultiana del Edipo Rey. Foucault se centra fundamentalmente en la relación entre saber y poder. Su lectura nos ofrece una interesante concepción simbólica de la verdad, cuyo desvelamiento seguiría las pautas de lo que Foucault llama “ley de las mitades”. El modo y los tiempos en que aparecen los diferentes fragmentos de la verdad, serán el centro de gravedad de su interpretación, esencialmente política. Proponemos, no obstante, ir un poco más allá de tan sugerente enfoque, reflexionando sobre las diferentes voces y perspectivas del texto, y preguntándonos, más allá del mero alcance político de la obra, por la voz del poeta, su posible significado filosófico, no sólo para los ciudadanos de su tiempo, sino también para nosotros.
El descenso de las estrellas. El mundo originario y el origen del mundo en el pensamiento de J. Patočka.
Authors: Garrido-Maturano Ángel Enrique
Published: July 2020

El artículo analiza desde una perspectiva fenomenológica y hermenéutica el modo originario de donación del mundo y el origen del mundo en el pensamiento de Jan Patočka posterior a 1965. Primero muestra en qué sentido tanto la donación del mundo como horizonte, cuanto los movimientos de la existencia humana, implican un vínculo esencial entre el modo originario de darse del mundo y la noción de infinito, concebido como lo indefinido e inagotable. Finalmente explicita por qué el vínculo del mundo con lo infinito reposa sobre un impulso creativo divino que constituye el fundamento cosmológico de la religiosidad humana.

Archivos familiares, propios y apropiados como cuerpos narrativos para una memoria genealógica
Authors: Sanjuán Ruth
Published: July 2020

Si la autobiografía, en tanto poética en el sentido platónico del término, ofrece la posibilidad de dar forma a las experiencias a través de su narración, convirtiendo lo que “pudo haber ocurrido” en “algo sucedido”, la memoria genealógica lo hace en relación a nuestro contexto más cercano y nuestras circunstancias más próximas. Nos proporciona un modo de contarnos a través de una visión más amplia, compleja y dilatada —en un sentido también temporal— gracias a la aportación no solo de uno, sino de varios miembros y tiempos. Estas genealógicas se yerguen como rizomas de historias cercanas e interconectadas entre sí que toman forma en su conjunto y donde el núcleo familiar es el centro de atención para contemplar y percibir nuestro entorno, haciendo convivir pasado y presente. El álbum familiar, en su disparidad y heterogeneidad, nos proporciona un modo de narrarnos en familia, de referirnos en relación con nuestros coetáneos, pasados y futuros. Cuenta de ello son los proyectos de las últimas décadas del siglo XX que recurren a un archivo fotográfico, algunos sobre un material disponible, legado, familiar, y otros a uno exclusivamente propio, o incluso a ambos.

If the autobiography, as poetic in the Platonic sense of the term, offers the possibility of shaping experiences through narration, transforming “something that could happen” into “something happened”, the genealogical memory does it in relation to our closest context and our closest circumstances. Offers us a way of counting through a broader more complex and expanded vision thanks to the contribution not only of one person, but of several members and several times also. We think about a this genealogies as a rhizome of connected stories that take shape as a whole, and the family nucleus is the center of attention that allows us to contemplate and perceive our environment, coexisting past and present. The family album, in the disparity and heterogeneity, provides us a way to autograph ourselves as a family, a way to tell ourselves about our contemporaries, past and future. An example of this are the projects of the last decades of the 20th century that are repeated in a photographic archive, some of them resorting to an available material, legacy, family, and others about own material, or even both.
El perfil competencial laboral de personas con discapacidad intelectual en centros ocupacionales
Authors: Jariot Garcia Mercè , Laborda Molla Cristina , González Fernández Henar
Published: July 2020

La inserción laboral repercute positivamente en el entorno del colectivo de personas con discapacidad intelectual (DI), y el empleo es decisivo en su proceso de integración social y participación comunitaria. Se pretenden optimizar los procesos de integración laboral y desarrollo profesional de las personas con DI leve y moderada para facilitar su inclusión social. Se realizó un muestreo no probabilístico de tipo incidental, en el que participaron 16 centros ocupacionales de la provincia de Barcelona. Se creó y aplicó un cuestionario a 100 personas con grados de DI leve y moderado. Se utilizó un diseño de investigación no experimental, en el que se analizaron las competencias profesionales de los participantes en su contexto natural (centros ocupacionales). Se constata una relación (positiva y moderada) estadísticamente significativa entre todas las competencias. Las personas con DI tienen un desarrollo similar en las competencias analizadas; las que presentan un grado de DI leve muestran niveles competenciales superiores a los de las personas con DI moderada. Es destacable que, independientemente del grado, todas las competencias evaluadas superen la puntuación media. Seguramente el hecho de que las personas analizadas estén ubicadas en centros ocupacionales es una variable que facilita su desarrollo competencial.

Labour integration has a positive impact on people with Intellectual Disability (ID), being employment a key element in their process of social integration and community participation. The aim of this research is to optimize the labour integration and professional development of people with mild and moderate ID in order to facilitate their social inclusion. A non-probabilistic incidental sampling was carried out, with the participation of 16 occupational centres of Barcelona’s metropolitan area. A questionnaire was created and administered to 100 people with mild and moderate ID. A non-experimental research design was used, in which the professional skills of the participants in their natural professional context (occupational centres) were analysed. Results show a statistically significant relationship (positive and moderate) between all the competences. People with ID have a similar development in the analysed competences; those with a low degree of ID show higher levels of competence than those with moderate ID. It is noteworthy that, regardless of the degree, all the evaluated competences exceed the average score. The fact that the participants in the research are located in occupational centres is certainly a variable that facilitates their competence development.
Calibración del resultado de una prueba escrita en estudiantes de ciencias de secundaria: el efecto del sexo
Authors: Ardura Diego , Galán Arturo
Published: July 2020

Durante las últimas décadas se han encontrado importantes diferencias por sexo en la enseñanza y el aprendizaje de las disciplinas científicas. Por otro lado, la autoevaluación por parte de los estudiantes supone un aspecto fundamental en el ciclo de autorregulación del aprendizaje y, por tanto, en su rendimiento. El objetivo de este trabajo es analizar la metacognición de los estudiantes de secundaria y, en particular, el efecto del sexo en las mismas. Para ello se ha medido la calibración de 507 estudiantes. Nuestros análisis muestran que las chicas calibran mejor su nota que los chicos a pesar de que estos últimos muestran más seguridad en sus juicios. Se ha encontrado una tendencia de ambos sexos a la sobreestimación de sus calificaciones en una prueba escrita. Por otro lado, los estudiantes con alto rendimiento son más precisos y tienden a sobrevalorar sus actuaciones. En cambio, los de rendimiento bajo son más imprecisos y tienden a subestimar sus calificaciones en la prueba. Aunque este efecto se observa en ambos sexos, su tamaño es superior en el caso de las chicas. En vista de los resultados, los estudiantes de rendimiento alto utilizan con más eficacia la retroalimentación que generan durante la prueba que los de rendimiento bajo. Las diferencias por sexo podrían tener su origen en las diferentes actitudes y motivaciones de los chicos y las chicas hacia la ciencia.

During the last decades, important sex differences have been found in the context of science education. Besides, self-assessment is crucial in the cycle of self-regulated learning and, consequently, in students’ performance. The main goal of the present investigation is to analyze secondary school students’ metacognition and, in particular, the effect of gender. To this aim, a sample of 507 students took part in our study. Our analyses show that girls are better calibrated than boys in spite of being the latter more confident in their predictions. A general tendency towards overestimations has been found for both sexes. Moreover, high-achieving students tend to be more precise and underestimate their performance and low-achieving students tend to be less precise and overestimate their grade in the test. Although this effect was found in both sexes, the size effect was large in the case of girls. In light of our results, high-achieving students make a better use of self-generated feedback than low-achievers. Sex differences in calibration could be explained by the different attitudes and motivations of boys and girls towards science.
La relación entre las competencias TIC, el uso de las TIC y los enfoques de aprendizaje en alumnado universitario de educación
Authors: Díaz-Garcia Isabel , Almerich Cerveró Gonzalo , Suárez-Rodríguez Jesús , Orellana Alonso Natividad
Published: July 2020

Las tecnologías de la información y de la comunicación (TIC) suponen un cambio en los modos de aprendizaje del alumnado universitario. El propósito de este estudio es conocer la relación entre los enfoques de aprendizaje (superficial y profundo), el uso de las TIC (uso personal, uso académico no escolar y uso académico en el aula) y las competencias TIC (tecnológicas, pedagógicas y éticas) en alumnado universitario de titulaciones de Educación. Se trata de un estudio basado en un diseño correlacional, cuya muestra la constituyen 485 estudiantes de las titulaciones de grado de Pedagogía y de Educación Social de la Universidad de Valencia, seleccionados mediante un muestreo no probabilístico y accidental, recogiendo la información mediante dos cuestionarios. Los resultados señalan la existencia de un vínculo complejo entre las competencias TIC, el uso de las TIC y los enfoques de aprendizaje. Se ha de destacar la relación entre las competencias pedagógicas y las éticas, el uso académico no escolar y el enfoque profundo, así como la relación entre enfoque superficial y uso académico de las TIC en el aula. Por ello, se sugiere la necesidad de formar a los estudiantes en las competencias pedagógicas y éticas de las TIC, ya que si se hiciera se estaría fomentando el aprendizaje profundo.

Information and communication technologies (ICT) represent a change in the ways of learning of university students. The purpose of this study is to know the relationship between learning approaches (superficial and deep), use of ICT (personal use, non-school academic use and academic use in the classroom) and ICT competences (technological, pedagogical and ethical) in university students of Education degrees. This is a study based on a correlational design, whose sample is made up of 485 students of the degrees of Pedagogy and Social Education at the University of Valencia, selected by non-probabilistic and accidental sampling, collecting the information through two questionnaires. The results indicate the existence of a complex link between ICT competences, use of ICT and learning approaches. The relationship between pedagogical and ethical competences, non-school academic use and an in-depth approach, and between a superficial approach and academic use of ICT in the classroom should be highlighted. Therefore, the need to train students in the pedagogical and ethical competences of ICT is stressed in order to encourage deep learning.

The Moment of Study in Learning that Resists Neoliberalism: Body Gesture, Time, and Play
Authors: Joldersma Clarence W.
Published: July 2020

The essay develops a case study about a young boy playing with a toy train to address neoliberalism’s problematic discourse that depicts learning as instrumental, as something that can be caused by teaching. This paper’s perspective is enactive, taking the view that central to understanding learning is not the mind or brain working in isolation but involves the interrelationships between mind/brain, body, and world. The analysis revolves around the standing gap between teaching and learning, where navigating the gap involves a dynamic called ‘the moment of study.’ Three of Tyson Lewis’s ideas about study—body gesture, time, and play—are used to explain the moment of study. The paper argues that a learner traverses the gap between teaching and learning through a body gesture of hesitation, during which there is a temporal turning away from the familiar and towards new possibilities. Traversing the gap occurs through the risk of improvisational play, propelling a forward movement in the face of not knowing how to go on. This depiction of such traversing, shown to be central to the activity of learning, undermines the causal account of learning associated with neoliberalism.
Novelty of Lin Zhaohua’s play “All people are Hamlets”
Authors: Ding Yi
Published: July 2020

The “Hamlet 1990” directed by Lin Zhaohua represents a variant of the Shakespeare’s “Hamlet”. The title of the play hints to the spirit of creative search and novelty, characteristic for the theater era of the 1990s. It was a specific socially transformative period, when “various Soviet-style creative positions were sacrificed” and china moved towards independent thinking and development of social reforms. It is possible that “Hamlet” performed in 1990 reflected these trends in social transformations, which led to the director’s interpretation and restructuring of Shakespeare’s play based on new views and independent aesthetic perception. “Revenge is a scene, a story” and the director acts as the storyteller; it is up to him how this story will be told. In accordance with methodology of the formal school, the author conducts a reconstruction of this play and analyses the scenic texts from the perspective of modern Chinese theater, as well as from the position of director’s style. “Hamlet 1990” directed by Lin Zhaohua became a new word in theatrical arts. In an open scenic space, the connection between the actors and the viewers is not unidirectional, but is two-way; there is an effect of transfer of psychological payload and emotional interaction between them.
Garage
Authors: Erlanger Olivia , Ortega Govela Luis
Published: July 2020

A secret history of the garage as a space of creativity, from its invention by Frank Lloyd Wright to its use by start-ups and garage bands.

Frank Lloyd Wright invented the garage when he moved the automobile out of the stable into a room of its own. Steve Jobs and Steve Wozniak (allegedly) started Apple Computer in a garage. Suburban men turned garages into man caves to escape from family life. Nirvana and No Doubt played their first chords as garage bands. What began as an architectural construct became a cultural construct. In this provocative history and deconstruction of an American icon, Olivia Erlanger and Luis Ortega Govela use the garage as a lens through which to view the advent of suburbia, the myth of the perfect family, and the degradation of the American dream.

The stories of what happened in these garages became self-fulfilling prophecies the more they were repeated. Hewlett-Packard was founded in a garage that now bears a plaque: The Birthplace of Silicon Valley. Google followed suit, dreamed up in a Menlo Park garage a few decades later. Also conceived in a garage: the toy company Mattel, creator of Barbie, the postwar, posthuman representation of American women. Garages became guest rooms, game rooms, home gyms, wine cellars, and secret bondage lairs, a no-commute destination for makers and DIYers—surfboard designers, ski makers, pet keepers, flannel-wearing musicians, weed-growing nuns. The garage was an aboveground underground, offering both a safe space for withdrawal and a stage for participation—opportunities for isolation or empowerment.
Recurrent circuitry is required to stabilize piriform cortex odor representations across brain states
Authors: Bolding Kevin A , Nagappan Shivathmihai , Han Bao-Xia , Wang Fan , Franks Kevin M
Published: July 2020

Pattern completion, or the ability to retrieve stable neural activity patterns from noisy or partial cues, is a fundamental feature of memory. Theoretical studies indicate that recurrently connected auto-associative or discrete attractor networks can perform this process. Although pattern completion and attractor dynamics have been observed in various recurrent neural circuits, the role recurrent circuitry plays in implementing these processes remains unclear. In recordings from head-fixed mice, we found that odor responses in olfactory bulb degrade under ketamine/xylazine anesthesia while responses immediately downstream, in piriform cortex, remain robust. Recurrent connections are required to stabilize cortical odor representations across states. Moreover, piriform odor representations exhibit attractor dynamics, both within and across trials, and these are also abolished when recurrent circuitry is eliminated. Here, we present converging evidence that recurrently-connected piriform populations stabilize sensory representations in response to degraded inputs, consistent with an auto-associative function for piriform cortex supported by recurrent circuitry.
Growth cone-localized microtubule organizing center establishes microtubule orientation in dendrites
Authors: Liang Xing , Kokes Marcela , Fetter Richard D , Sallee Maria Danielle , Moore Adrian W , Feldman Jessica L , Shen Kang
Published: July 2020

A polarized arrangement of neuronal microtubule arrays is the foundation of membrane trafficking and subcellular compartmentalization. Conserved among both invertebrates and vertebrates, axons contain exclusively ‘plus-end-out’ microtubules while dendrites contain a high percentage of ‘minus-end-out’ microtubules, the origins of which have been a mystery. Here we show that in Caenorhabditis elegans the dendritic growth cone contains a non-centrosomal microtubule organizing center (MTOC), which generates minus-end-out microtubules along outgrowing dendrites and plus-end-out microtubules in the growth cone. RAB-11-positive endosomes accumulate in this region and co-migrate with the microtubule nucleation complex γ-TuRC. The MTOC tracks the extending growth cone by kinesin-1/UNC-116-mediated endosome movements on distal plus-end-out microtubules and dynein clusters this advancing MTOC. Critically, perturbation of the function or localization of the MTOC causes reversed microtubule polarity in dendrites. These findings unveil the endosome-localized dendritic MTOC as a critical organelle for establishing axon-dendrite polarity.
Sleep spindles mediate hippocampal-neocortical coupling during long-duration ripples
Authors: Ngo Hong-Viet , Fell Juergen , Staresina Bernhard
Published: July 2020

Sleep is pivotal for memory consolidation. According to two-stage accounts, memory traces are gradually translocated from hippocampus to neocortex during non-rapid-eye-movement (NREM) sleep. Mechanistically, this information transfer is thought to rely on interactions between thalamocortical spindles and hippocampal ripples. To test this hypothesis, we analyzed intracranial and scalp Electroencephalography sleep recordings from pre-surgical epilepsy patients. We first observed a concurrent spindle power increase in hippocampus (HIPP) and neocortex (NC) time-locked to individual hippocampal ripple events. Coherence analysis confirmed elevated levels of hippocampal-neocortical spindle coupling around ripples, with directionality analyses indicating an influence from NC to HIPP. Importantly, these hippocampal-neocortical dynamics were particularly pronounced during long-duration compared to short-duration ripples. Together, our findings reveal a potential mechanism underlying active consolidation, comprising a neocortical-hippocampal-neocortical reactivation loop initiated by the neocortex. This hippocampal-cortical dialogue is mediated by sleep spindles and is enhanced during long-duration hippocampal ripples.
Test Methods for Fibre/Matrix Adhesion in Cellulose Fibre-Reinforced Thermoplastic Composite Materials: A Critical Review
Authors: Müssig J. , Graupner N.
Published: July 2020

Due to the increasing discussion about sustainable and CO2-reduced materials, the demand for cellulose-based fibres as a reinforcing component in thermoplastic composites has increased considerably. Knowledge about the possibilities of modifying fibres for improved adhesion
to the plastic matrix is essential in this context. The fibre/matrix adhesion in cellulose fibre-reinforced polymers is of considerable importance for the design of composite materials. Unfortunately, there are no standards for many essential methods to determine fibre/matrix adhesion. In
this review article, various methods for measuring the interfacial shear strength between fibres and matrix, as an indirect characterisation of adhesion, are presented. Additionally, a brief overview of different methods for surface modification of cellulose fibres to improve the adhesion
to a thermoplastic matrix is given. This review focuses on the fact that the parameters for the production of test specimens as well as the test method itself can vary considerably from study to study. Because of this, the comparison of data from different publications is not always possible.
Therefore, in this article, the main influencing factors and differences in the methods are presented and discussed. Based on a systematic review and a clear description and discussion of the methods, the reader is given a broad basis for a better understanding of characteristic values for
fibre/matrix adhesion.
Bio-Inspired Icephobic Coatings for Aircraft Icing Mitigation: A Critical Review
Authors: Ma Liqun , Zhang Zichen , Gao Linyue , Liu Yang , Hu Hui
Published: July 2020

A critical review is provided to summarize our recent efforts to utilize the state-of-the-art bio-inspired icephobic coatings/surfaces, i.e., 1). Lotus-leaf-inspired superhydrophobic surfaces (SHS) and 2). Pitcher-plant-inspired slippery liquid-infused porous surfaces (SLIPS) for aircraft
icing mitigation. By leveraging the unique Icing Research Tunnel of Iowa State University (i.e., ISU-IRT), an experimental campaign was performed to evaluate the effectiveness of using SHS and SLIPS coatings to suppress impact ice accretion over the surfaces of typical airfoil/wing models.
While both SHS and SLIPS were found to be able to suppress ice accretion over the airframe surfaces where strong aerodynamic forces are exerted, ice was still found to accrete in the vicinity of the airfoil stagnation line where the aerodynamic forces are at their minimum. A novel hybrid anti-/de-icing
strategy concept to combine icephobic coatings with minimized surface heating near airfoil leading edge was demonstrated to effectively remove impact ice accretion over entire airfoil/wing surfaces. An experimental investigation was also conducted to examine the durability of the icephobic
coatings/surfaces to resist "rain erosion" effects (i.e., the damage to the surface coatings due to continuous impingement of water droplets at high speeds) in considering the practical usage for aircraft icing mitigation. The rain erosion effects were characterized based on the variations
of the ice adhesion strengths and surface morphology of the eroded test surfaces coated with SHS and SLIPS. The research findings are very helpful to elucidate the underlying physics for the development of novel and robust anti-/de-icing strategies for aircraft icing mitigation.
Bioinformatics analysis and identification of circular RNAs promoting the osteogenic differentiation of human bone marrow mesenchymal stem cells on titanium treated by surface mechanical attrition
Authors: Zhu Shanshan , Zhu Yuhe , Wang Zhenbo , Liang Chen , Cao Nanjue , Yan Ming , Gao Fei , Liu Jie , Wang Wei
Published: July 2020

Background

To analyze and identify the circular RNAs (circRNAs) involved in promoting the osteogenic differentiation of human bone mesenchymal stem cells (hBMSCs) on titanium by surface mechanical attrition treatment (SMAT).

Methods

The experimental material was SMAT titanium and the control material was annealed titanium. Cell Counting Kits-8 (CCK-8) was used to detect the proliferation of hBMSCs, and alkaline phosphatase (ALP) activity and alizarin red staining were used to detect the osteogenic differentiation of hBMSCs on the sample surfaces. The bioinformatics prediction software miwalk3.0 was used to construct competing endogenous RNA (ceRNA) networks by predicting circRNAs with osteogenesis-related messenger RNAs (mRNAs) and microRNAs (miRNAs). The circRNAs located at the key positions in the networks were selected and analyzed by quantitative real-time PCR (QRT-PCR).

Results

Compared with annealed titanium, SMAT titanium could promote the proliferation and osteogenic differentiation of hBMSCs. The total number of predicted circRNAs was 51. Among these, 30 circRNAs and 8 miRNAs constituted 6 ceRNA networks. Circ-LTBP2 was selected for verification. QRT-PCR results showed that the expression levels of hsa_circ_0032599, hsa_circ_0032600 and hsa_circ_0032601 were upregulated in the experimental group compared with those in the control group; the differential expression of hsa_circ_0032600 was the most obvious and statistically significant, with a fold change (FC) = 4.25 ± 1.60, p-values (p) < 0.05.

Published: July 2020

In this study, the development and physicochemical of MMFM (minor millet flour mix) and sensory qualities of  MMFM chapathis (unleavened Indian flatbread) were evaluated at different proportions. Flour mixes were developed blending of minor millet flour and Nutri-cereals flours with wheat flour in different rations V1(75:25:0) (Millets: Other grains: Wheat flour), V2(60:25:15) V3 (50:25:25) V4(45:25:30), V5(30:25:45) V6(0: 75: 25) V7(100) and V8 (100 without gums) respectively and 100% wheat flour used as control. The functional properties of flours mixes were tested and results revealed that swelling capacity, water absorption capacity, oil absorption capacity, gelatinization temperature, water retention capacity and bulk density were increased with an increase in the incorporation of other flours with wheat flour. Further, the color values of millet-based chapathis showed significant changes when the level of millet flour substitution was increased. The L* and b* values decreased while a* value increased. Regarding sensory properties, control wheat chapathis had better acceptability than the composite chapathis. Sensory evaluation revealed that overall acceptability for millet and nutricereals flour-based chapathis was awarded the highest score for V6 followed by V5, V4, and V3 as compared to control Chapathi. All chapathis were coinciding the range of ‘like moderately’ to ‘like very much’ for control chapathis while ‘like slightly’ to like moderately’ for experimental chapathis. Based on the generated results, novel chapathis could be formulated by substituting wheat with more than 50% flour.
Role of Fluoride on Soil, Plant and Human Health: A Review on Its Sources, Toxicity and Mitigation Strategies
Authors: Chatterjee Nitin , Sahu Gayatri , Bag Animesh Ghosh , Plal Biplab , Hazra G. C.
Published: July 2020

In recent scenario, fluorosis is now going to be a severe problem throughout the globe due to toxic effects of fluoride (F) on both plants, animals and humans. Natural geological sources and increased industrialization have contributed greatly to the increasing incidence of F-induced human and animal health issues. The toxic effects of high doses of F may adversely affect human health by causing skeletal fluorosis, dental fluorosis, bone fractures, the formation of kidney stones, decreased birth rates, weakening of thyroid functionality and impair intelligence, particularly in children. High concentrations of F in soil may seriously threaten the life of plants, devastate soil microbial activity, disrupt the soil ecology and causes soil and water pollution. Hydrogen fluorides (HF) in gaseous form accumulated in the leaves of sensitive plants against a concentration gradient and HF mainly damages the plant by entering into its body in the form of gas and affects a variety of plant physiological processes. In this review we discuss about the effect of fluoride toxicity on plant, human and soil health and its mitigation strategies.

Group 4: No DDVP, No palm oil for 14 days (Negative control), Group 5: 10 mg/kg of DDVP without palm oil daily for 14 days (positive control), Group 6: 10 mg/kg of DDVP and 100 mg/kg of palm oil daily for 14 days (positive control). Phase 3: Sub-Chronic (30 days) Study. Group 7: No DDVP, No palm oil for 30 days (Negative control), Group 8: 10 mg/kg of DDVP without palm oil daily for 30 days (positive control), Group 9: 10 mg/kg of DDVP and 100 mg/kg palm oil daily for 30 days (treatment group). All administration was done orally. After the period of treatments, the rats were sacrificed after 18 hours of fast. Whole blood samples (5 mls) were collected into lithium heparin bottle and spun at 3500 rpm for 5 minutes to obtain plasma samples. Samples obtained were used for the determination of Na+, K+, HCO3, urea, and creatinine while renal tissues obtained were used for histopathological examinations.

Results: Significantly higher values were seen in urea in the dichlorvos treated rats over a period of 24 hours, 14 days, and 30 days as compared to rats co-treated with palm oil and the control. Creatinine indicated significantly higher over a period of 24 hours while non-significant increases were observed in the dichlorvos treated rats over a period of 14 days and 30 days. More so, significantly higher values were seen in potassium in the dichlorvos treated rats over a period of 24 hours and 14 days, while significantly higher values in potassium were seen after period of 30 days as compared to rats co-treated with palm oil and the control. Sodium and chloride did not indicate significant difference over the period of 24 hours, 14 days, and 30 days. Histological examination of the renal tissue indicated structural distortions dichlorvos treated rats over a period of 24 hours, 14 days and 30 days while significant improvements in the structural integrity of the kidney were observed in rats co-treated with palm oil.

Conclusion: Results obtained indicated that palm oil showed a protective effect in ameliorating the nephrotoxicity induced by dichlorvos as shown by the histological examination and decreased values of creatinine and urea as well as potassium in palm oil treated rats.
Comparison of Optimization of Exergy Efficiency of a Crude Distillation Unit Using Artificial Neural Network (ANN) and Response Surface Methods (RSM)
Authors: Braimah M. N.
Published: July 2020

The study carried out simulation of the Crude Distillation Unit (CDU) of the New Port Harcourt Refinery (NPHR) and performed exergy analysis of the Refinery. The Crude Distillation Unit (CDU) of the New Port Harcourt refinery was simulated using HYSYS (2006.5).

The Atmospheric Distillation Unit (ADU) which is the most inefficient unit and where major separation of the crude occurs was focused on. The simulation result was exported to Microsoft Excel Spreadsheet for exergy analysis. The ADU was optimized using statistical method and Artificial Neural Network. Box-Behnken model was applied to the sensitive operating variables that were identified. The statistical analysis of the RSM was carried out using Design Expert (6.0). Matlab software was used for the Artificial Neural Network. All the operating variables were combined to give the best optimum operating conditions.

Exergy efficiency of the ADU was 51.9% and 52.4% when chemical exergy was included and excluded respectively. The optimum operating conditions from statistical optimization (RSM) are 586.1 K for liquid inlet temperature, 595.5 kPa for liquid inlet pressure and condenser pressure of 124 kPa with exergy efficiency of 69.6% which is 33.0% increment as compared to the base case.

For the ANN optimization, the exergy efficiency of the ADU was estimated to be 70.6%. This gave an increase of 34.9% as compared to the base case.

This study concluded that enormous improvement can be achieved both in design feasibility and improved efficiency if the feed operating parameters and other sensitive parameters are carefully chosen. Furthermore, ANN optimization gave better exergy efficiency of 70.6% than RSM optimization of 69.6%.
Agricultural Sector Linkage with Other Sectors of the Economy: Evidence from Nigeria
Authors: Kelikume Ikechukwu , Nwani Stanley Emife
Published: July 2020

Economic resource planners have continued to harness proven empirical link amongst various sectors of the economy for effective policy formulation and implementation of successful growth and development strategies. The Agricultural sector is one of the sectors that have consistently contributed to other sectors of the economy in terms of provision of raw materials, food and employment to the growing population; however, the need to understand the forward and backward linkages between the agricultural sector output and other sectors’ output has prompted this study. This paper investigates the causal link between the Agricultural sector output and Industry, Construction, Trade and Services sectors output using quarterly times series data extracted from the annual statistical bulletin of the Central Bank of Nigeria from the first quarter 2010 to the fourth quarter 2018. The study departs from the traditional static Leontief Input-Output approach by employing dynamic modern techniques like the Granger Causality, Vector Autoregression, Impulse Response and Variance Decomposition analyses. The results indicate the existence of bi-directional causal chain effect linkages between agricultural sector output, services, construction and trade outputs while a unidirectional causal linkage is found running from industrial sector output to agriculture. All the sectors drive agricultural sector output and agriculture stimulates other sectors except the industrial sector. In specific terms, it takes approximately two to four quarters for most sectors to respond to the impact of shocks emanating from the other sectors the economy. For the agricultural sector to play its pivot role as the driver of other sectors the study suggests that should be remodeled in such a way that its outputs meet industrial sector requirement.

Objetivo: compreender o significado do ensino da consulta de enfermagem com abordagem sindrômica para enfermeiros. Método: pesquisa qualitativa, sustentada na Fenomenologia Social, realizada com 19 enfermeiros docentes e assistenciais de quatro hospitais universitários da região metropolitana do Rio de Janeiro, em 2013. Os depoimentos foram analisados e organizados em categorias concretas do vivido. Resultados: destacaram-se as categorias: “Demonstrar a prática da consulta de enfermagem com abordagem sindrômica”, “Oportunizar o desenvolvimento de habilidades e competências para a consulta de enfermagem” e “Compartilhar a intencionalidade do ensino da consulta de enfermagem”. Conclusões: constatamos que os Enfermeiros se vêem como “seres docentes”, sendo esse comportamento determinante de suas ações, independente da sua formação acadêmica, pois se pautam em sua ação intencional de ensinar, apreendida na intersubjetividade da relação face a face com os graduandos e pós-graduandos, possibilitando à sua consciência o reconhecimento da prática do ensino da Consulta de Enfermagem como única e fundamentada.
