Necesidad de un pensamiento «polar» para recuperar teológica y estructuralmente las Iglesias locales
Authors: Polanco Rodrigo
Published: March 2020

¿Por qué no ha sido posible caminar más resueltamente hacia una recuperación teológica y estructural de la Iglesia local en el conjunto de la Iglesia universal? El artículo plantea la hipótesis de que ha sido la falta de conciencia acerca de la constitución irreductiblemente polar de la Iglesia lo que ha dificultado avanzar en ese sentido. Y, a partir de LG 23, y de un estudio sobre los fundamentos teológico-históricos de la catolicidad desde la localidad, propone algunas reformas que son hoy más urgentes y que desde una mirada dual, encuentran un mayor sustento teológico para su implementación. Se trata de fortalecer una mirada desde lo local, es decir, desde la base. Es más, conforme tanto con los inicios de la Iglesia como a la sensibilidad actual.

Proposals for Using the NFC Technology in Regional Passenger Transport in the Slovak Republic
Authors: Brumercikova Eva , Bukova Bibiana
Published: March 2020

NFC (Near Field Communication) devices are used in contactless payment systems, similar to those used in credit cards and electronic ticket smart cards, and they allow a mobile payment to replace or supplement these systems. The trend of increasing the quality of transport services also includes the use of progressive information technologies. The article focuses on the use of NFC technology in regional passenger transport. In the first proposal, the implementation of NFC technology in the form of an electronic wallet in a regional contactless chip card is being considered. In the second proposal we deal with the implementation of NFC technology in regional passenger transport using mobile phones with an active NFC chip. The proposals use Check-In/Check-Out validation, where validators are placed in vehicles. In both proposals it would be possible to create a link to EMV (Europay/MasterCard/VISA) technology, and thus to provide a linking of a contactless smart card, possibly a mobile phone to the passenger’s personal account.

Authors: Gnap Jozef , Riha Zdenek , Semanova Stefania
Published: March 2020

The introduction of the paper highlights best practice in the area of deploying autonomous trucks in warehouses and the automotive industry, including the current technical possibilities of selected autonomous trucks. The next chapter presents the selected outputs of the scientific project “Center of Excellence for Intelligent Transport Systems” focused on a proposal of the methodology for calculating the necessary number of autonomous trucks and trolleys deployed in logistics warehouses. The methodology is based on the requirement that autonomous trucks do not have downtime. This represents a model solution with possible application in warehouse logistics but also in the automotive industry. The follow-up chapter proposes a methodological procedure to evaluate the efficiency of introducing autonomous trucks to pull trolleys in a logistics warehouse compared to conventional trucks operated by trained personnel. Autonomous trucks can theoretically be operated 365 days and 24 hours depending on the technology of their operation, battery charging, etc. On the other hand, there is generally a shortage of logistics personnel in the European Union as well as reliability and performance have been declining in recent years. The conclusion of the paper includes a discussion of the research results obtained and possibilities for future research.

Authors: Loga-Księska Wiktoria , Sordyl Justyna , Ryguła Artur
Published: March 2020

Increasing the number of vehicles on the road network and the growing popularity of sustainable development of urban areas have resulted in the need for implementing efficient and cost-effective traffic measurement methods. From the perspective of traffic management, up-to-date information about vehicle density and access to historical data are the key components of traffic variability analyses. Rapid technological development based on Intelligent Transport Systems (ITS) has popularised the wireless sensor networks (WSN) application. The solution enables continuous monitoring of selected area using multiple wireless and low-cost sensors connected within a network. Those systems are dynamically evolving tools for solving an effective traffic management issues in city centres and urban environments. In the study, authors have performed a traffic variability and its dynamics analysis in a selected area using a multi-sensor network for traffic volume monitoring. The article presents the results of research conducted between years 2015 - 2018 throughout the city of Bielsko-Biala with the support of OnDynamic multimodal system. Within the context of the analyses, basic traffic parameters have been determined and variability trends have been identified on selected road sections. Long-term research indicated the minor variation in a number of vehicle detections and relatively stable traffic volume in the city centre during the analysis period.
Isatin as a simple, highly selective and sensitive colorimetric sensor for fluoride anion
Authors: Haider Azeem , Ahmed Mukhtiar , Faisal Muhammad , Naseer Muhammad Moazzam
Published: March 2020

Herein, we report the fluoride anion sensing properties of a commercially available and inexpensive organic compound, isatin, which is found to be a highly selective and sensitive sensor. In naked-eye experiments, by addition of fluoride anions, isatin shows a dramatic color change from pale yellow to violet at room temperature, while the addition of other anions,i.e.Cl−,$\mathrm{Cl}^-,$Br−,I−,ClO4−,H2PO4−andPF6−,$\mathrm{Br}^-,\mathrm I^-,\mathrm{ClO}_4^-,{\mathrm H}_2\mathrm{PO}_4^-\,\mathrm{and}\,\mathrm{PF}_6^-,$did not induce any colour change. Additionally, recognition and titration studies have also been done through UV/Vis spectroscopy. Isatin displayed a new absorption band at 533 nm after the addition of fluoride anions, which is presumably due to acid-base interaction between isatin and fluoride anions, while other anions did not trigger noticeable spectral changes. The detection limit was observed to be 0.367 ppm. DFT calculations were also performed to further explain the behavior of receptor 1 towards the Fˉ anion. Owing to high sensitivity and selectivity, isatin can be useful in the detection of biologically or environmentally important fluoride anions at very low concentration.
Ball-Type Dioxy-o-Carborane Bridged Cobaltphthalocyanine: Synthesis, Characterization and DFT Studies For Dye-Sensitized Solar Cells as Photosensitizer
Authors: Şener Sevil
Published: March 2020

The synthesis and spectroscopic characterization of an innovative ball-type cobalt metallophthalocyanine 4, bridged by four 1,2-bis(2-hydroxymethyl)-O-carborane (HMOC) 1 units, has been achieved. The synthesized compound 4 was characterized structurally and electronically using elemental analysis, UV-Vis absorption spectroscopy, FT-IR spectroscopy, MALDI-TOF mass spectrometry, EPR spectroscopy and magnetic susceptibility. The photovoltaic performance of the newly synthesized compound in dye-sensitized solar cells was investigated. In order to clarify the effect of dye-sensitization time on photovoltaic performance parameters, the sensitization time was varied from 12 to 60 h and the performance parameters were investigated. It was found that sensitization time had a strong effect on the main performance parameters. The best photovoltaic performance was achieved after sensitization for 36 h (short circuit current density, 5.41 mA cm−2; overall conversion efficiency, 3.42%). Computational UV-Vis absorption spectra of the molecule was calculated using time dependent density functional theory and was found consistent with measured UV-Vis spectra.
Crystallographic orientation of ilmenite inclusions in amphibole – an electron backscatter diffraction study
Authors: Xu Chang , Zhao Shanrong , Zhou Jiaohua , He Xu , Xu Haijun
Published: March 2020

Orientated ilmenite inclusions have been discovered in amphibole of hornblendite from the Zhujiapu area, Dabie ultra-high-pressure (UHP) metamorphic terrane, China. In order to characterize the crystallographic orientation relationships between ilmenite inclusions and amphibole host and reconstruct the mechanism of their formation, we present an electron backscatter diffraction (EBSD) analysis combined with energy dispersive spectroscopy (EDS) analysis and electron microprobe analysis (EPMA) for ilmenite inclusions and amphibole host. The inclusions can be subdivided into four groups: (1) 60.2% of ilmenites have the crystallographic orientation {0001}Ilm// {100}Amp, (101̅0)Ilm// {010}Amp, [112̅0]Ilm// <001> Ampand [112̅0]Ilm// <012 > Amp. (2) 16.5% of ilmenites have <0001> Ilm// <001> Amp, (101̅0)Ilm// {010}Amp, (112̅0)Ilm// {100}Ampand [3̅031]Ilm// <012> Amp. (3) 13.8% of ilmenites have <0001> Ilm// <012> Amp, (112̅0)Ilm// {100}Ampand [3̅031]Ilm// <001> Amp. (4) 9.5% of ilmenites have <0001> Ilm// [1̅12]Amp, (101̅0)Ilm// {201}Amp, [112̅0]Ilm// [1̅12]Ampand[1121¯]Ilm${[11\overline {21} ]_{Ilm}}$// <010> Amp. By comparing the lattice relationship between ilmenite inclusions and amphibole hosts, it is shown that the frequency of the ilmenite inclusions in different groups is related to the lattice coherency and oxygen packing. Group-1 of the ilmenite inclusions was most likely be formed via a solid-state exsolution process by cooling of the hornblendite after the intrusion was emplaced. The other three groups of ilmenite inclusions were probably formed via reduction reaction in an open system. The formation temperature of the ilmenite inclusions is estimated by using the TiO2solubility geothermeter in amphibole. The minimum formation temperature of the ilmenite inclusions is about 1025 °C, and the maximum formation temperature of the ilmenite inclusions is about 1126 °C.

Published: March 2020

Presentamos un estudio de investigación desde el enfoque del neuromarketing cuyo objetivo es verificar la capacidad de la tecnología Sociograph para evaluar las reacciones de atención y emoción en el visionado de material erótico y verificar si la metodología empleada es capaz de discriminar reacciones diferenciales aplicables a las estrategias de marketing. Se presenta una aplicación práctica de la señal electrodérmica (EDA) como metodología para medir la conducta grupal mediante la tecnología Sociograph. Considerando las variables emoción y atención determinantes en el proceso de persuasión se propone un estudio exploratorio en el que se analiza la respuesta atencional y emocional de dos grupos (varones N=8 y mujeres N=8) en el visionado de material erótico. Los resultados indican un patrón de activación diferenciado. Mientras que ambos grupos muestran alta activación inicial, solo el grupo de varones reduce su activación durante el tramo más erótico. Se plantean posibles aplicaciones a las estrategias de marketing según resultados, así como la necesidad de incluir metodologías procedentes de la neurociencia al estudio del consumidor, que  contemplen distintos escenarios del visionado del material para poder evaluar respuestas tanto en situaciones de visionado individual como grupal.

Hollywood y el Pentágono. La producción cultural propagandística del Departamento de Defensa de los Estados Unidos.
Authors: Vega Durán Samuel
Published: March 2020

El Departamento de Defensa de los Estados Unidos y Hollywood mantienen una larga y próspera relación productiva. El Pentágono ayuda a la producción y financiación de diversas películas con la condición de poder hacer modificaciones de guion e influir en las representaciones que la película hace de los Estados Unidos y su ejército. Este trabajo analiza las últimas películas en las que ha participado el Pentágono desde 2015 para tratar de concretar cuáles son los posibles elementos propagandísticos comunes a estas obras que podrían catalogarlas como piezas de comunicación persuasiva o manipulativa. A través de un análisis del discurso aplicado a la muestra se han identificado diversas estrategias narrativas y representacionales recurrentes en las distintas películas que, en conjunto, componen una estrategia propagandística clara y sostenida en el tiempo de la investigación. El cine influido por el Departamento de Defensa estadounidense funciona como una herramienta para la legitimación y promoción de la hegemonía global norteamericana mediante la construcción de representaciones maniqueístas del ejército y del poder político de Estados Unidos.

Brand Management y tribu consumidora. Un estudio aplicado a las marcas de surf españolas
Authors: Sanz-Marcos Paloma
Published: March 2020

Esta investigación se propone profundizar en la noción de tribu consumidora desde la óptica del branding tribal. La articulación de los consumidores a través de este tipo agrupación comporta una serie de implicaciones con respecto al estudio de la marca que, de manera directa, afecta a las estrategias clásicas de brand management. Para ello, se ha tomado como objeto de estudio a una potencial tribu consumidora específica, los surfistas españoles, así como a los responsables de marketing de aquellas marcas de surf más representativas que operan en el mercado español con objeto de vislumbrar el alcance de la concepción de la marca que surge a partir del concepto tribal, tanto en sus dimensiones de recepción y consumo como en lo relativo a su posible modelo de gestión. La metodología se ha basado en la realización de 11 entrevistas en profundidad a los gestores de las marcas de surf más representativas que operan en el mercado español, y en la celebración de 4 focus groups con un total de 29 participantes procedentes de aquellas zonas españolas donde la práctica del surf tiene mayor presencia. Los resultados indican que el marketing tribal ofrece una versión radical de los paradigmas clásicos del estudio de la marca evidenciado, principalmente, en un problema categorial manifestado en una escasa sofisticación de los profesionales que gestionan esta industria en España.
Heat Treatment and Impact Toughness of the F55-Grade Steel
Authors: Rivolta Barbara , Gerosa Riccardo , Tavasci Francesca
Published: March 2020

Low-temperature impact tests are commonly performed to test the quality of industrial forgings in Duplex Stainless Steels (DSS). The F55 grade is a highly alloyed Super DSS characterized by excellent low-temperature toughness in the solution annealed condition. Because of the rich chemical composition, it is very prone to precipitation phenomena during quenching. This research investigates the effect of the material cooling rate on the impact toughness of a water-quenched F55 steel, characterized by the absence of σ-phase. Furthermore, by elaborating the impact test data, the T45J [°C] and the KV−46°C [J] parameters have been identified. They are two indicators based on the austenite/ferrite ratio and the material cooling rate, useful for predicting the material impact behavior prior to testing.
Enabling Advanced Process Control for Manual Grinding Operations
Authors: Kamath Akshay Katapadi , Linke Barbara S. , Chu Chih-Hsing
Published: March 2020

Manual grinding is an abrasive manufacturing process commonly employed in the automotive, aerospace, and medical industries for deburring, finishing, and engraving operations. Unlike other manufacturing processes in which automation drives constant improvement, the operator’s skill set continues to play a pivotal role in manual grinding. Process parameters such as grinding force and feed rate are dependent on the pressure and manual feed rate provided by the operator as well as the operator’s tool movement during the process. Therefore, it is essential to quantify the manual skills involved in the process in order to develop a real-time feedback system, which can assist the operator for in-process corrective action. Manual operations such as manual grinding have not fully utilized the Industrial Internet of Things yet. This article focuses on developing a robust experimental setup to effectively monitor operator-controlled variables (tool feed rate and tool circumferential speed) and process information variables (grinding force, workpiece acceleration, and grinding power). Experiments are carried out to understand the relationships between the variables and their impacts on process outcomes (surface roughness and material removal rate). In addition, grinding energy is evaluated to improve grinding efficiency and sustainability. The developed test setup consists of a power tool, a piezoelectric force sensor, a motion-tracking–based feed rate sensor, and additional sensors. An alumina sanding band is used to grind aluminum 6061-T6 and hardened steel AISI 416 workpieces. Profilometer and confocal surface measurements are carried out for the test specimens to assess various two-dimensional and three-dimensional surface roughness parameters. Findings derived from the experimental results may lay a foundation for understanding and controlling manual grinding operations and enable their integration in smart and sustainable manufacturing systems.
β4-Nicotinic Receptors Are Critically Involved in Reward-Related Behaviors and Self-Regulation of Nicotine Reinforcement
Authors: Husson Marianne , Harrington Lauriane , Tochon Léa , Cho Yoon , Ibañez-Tallon Inés , Maskos Uwe , David Vincent
Published: March 2020

Nicotine addiction, through smoking, is the principal cause of preventable mortality worldwide. Human genome-wide association studies have linked polymorphisms in theCHRNA5-CHRNA3-CHRNB4gene cluster, coding for the α5, α3, and β4 nicotinic acetylcholine receptor (nAChR) subunits, to nicotine addiction. β4*nAChRs have been implicated in nicotine withdrawal, aversion, and reinforcement. Here we show that β4*nAChRs also are involved in non-nicotine-mediated responses that may predispose to addiction-related behaviors. β4 knock-out (KO) male mice show increased novelty-induced locomotor activity, lower baseline anxiety, and motivational deficits in operant conditioning for palatable food rewards and in reward-based Go/No-go tasks. To further explore reward deficits we used intracranial self-administration (ICSA) by directly injecting nicotine into the ventral tegmental area (VTA) in mice. We found that, at low nicotine doses, β4KO self-administer less than wild-type (WT) mice. Conversely, at high nicotine doses, this was reversed and β4KO self-administered more than WT mice, whereas β4-overexpressing mice avoided nicotine injections. Viral expression of β4 subunits in medial habenula (MHb), interpeduncular nucleus (IPN), and VTA of β4KO mice revealed dose- and region-dependent differences: β4*nAChRs in the VTA potentiated nicotine-mediated rewarding effects at all doses, whereas β4*nAChRs in the MHb-IPN pathway, limited VTA-ICSA at high nicotine doses. Together, our findings indicate that the lack of functional β4*nAChRs result in deficits in reward sensitivity including increased ICSA at high doses of nicotine that is restored by re-expression of β4*nAChRs in the MHb-IPN. These data indicate that β4 is a critical modulator of reward-related behaviors.

SIGNIFICANCE STATEMENTHuman genetic studies have provided strong evidence for a relationship between variants in theCHRNA5-CHRNA3-CHRNB4gene cluster and nicotine addiction. Yet, little is known about the role of β4 nicotinic acetylcholine receptor (nAChR) subunit encoded by this cluster. We investigated the implication of β4*nAChRs in anxiety-, food reward- and nicotine reward-related behaviors. Deletion of the β4 subunit gene resulted in an addiction-related phenotype characterized by low anxiety, high novelty-induced response, lack of sensitivity to palatable food rewards and increased intracranial nicotine self-administration at high doses. Lentiviral vector-induced re-expression of the β4 subunit into either the MHb or IPN restored a “stop” signal on nicotine self-administration. These results suggest that β4*nAChRs provide a promising novel drug target for smoking cessation.

Josip Franjo (ili Josephus Franciscus) Domin (1754. – 1819.) bio je hrvatski fizičar koji je predavao na sveučilištima u Győru i Pešti. Poznat je po knjizi Dissertatio physica de aeris factitii genesi, natura, et utilitatibus (Fizikalna rasprava o postanku, naravi i koristi umjetnog zraka), Győr, 1784. U Raspravi je opisao više vrsta “umjetnog zraka”, što ih je većinom otkrio Joseph Priestly, a usto postupke i uređaje za njihovo dobivanje te – u drugom dijelu knjige – njihovu upotrebu. U ovom radu raspravlja se o Dominovom opisu eudiometra, uređaja za mjerenje sadržaja kisika (“deflogistoniranog zraka”) u plinskim smjesama njegovom reakcijom s “nitroznim zrakom”, dušikovim(I) oksidom (NO), što ga je izumio Priestley a usavršio Felice Fontana. Naročito je istražena veza “dobrote zraka” s flogistonskom teorijom i teorijom mijazama u Dominovoj Raspravi.

Membranska filtracija kao ekološki prihvatljiva metoda pročišćavanja sirovog biodizela
Authors: Ostojčić Marta , Budžaki Sandra , Zelić Bruno , Tišma Marina , Brkić Sanja
Published: March 2020

Biodizel je prvo alternativno gorivo čija su fizikalno-kemijska svojstva regulirana odgovarajućim standardima: američkim ASTM D 6751 i europskim standardom EN 14214. Proces proizvodnje biodizela sastoji se od tri glavne faze: 1) pripreme sirovine, 2) transesterifikacije i 3) obrade produkta reakcije – pročišćavanje sirovog biodizela kako bi se zadovoljile specifikacije koje su navedene u prethodno spomenutim standardima. Proces pročišćavanja sirovog biodizela obično se provodi dvjema tehnikama: vlažnim i suhim pranjem. Najčešće primjenjivani postupak je mokro pranje. Glavni nedostatak u upotrebi vode u procesu pročišćavanja je stvaranje velike količine otpadne vode koja uvelike povećava troškove proizvodnje biodizela nakon čega slijedi sušenje proizvoda, što zahtijeva dodatni utrošak energije i vremena. Najveći nedostatak suhog pranja s različitim ionsko-izmjenjivačkim smolama je nemogućnost uklanjanja glicerola i metanola iz sirovog biodizela do onih granica koje su propisane EN 14214 te problem odlaganja iskorištenih ionsko-izmjenjivačkih smola. Zbog toga se kao alternativa postojećim tehnikama pročišćavanja pojavila primjena membranske tehnologije u procesu pročišćavanja biodizela. Membranska filtracija je ekološki prihvatljiva i zahtijeva manje energije. Membranskom filtracijom može se smanjiti udio glicerola, metanola i vode u biodizelu do količina propisanih standardima. U okviru ovog rada prikazan je kratki pregled mogućnosti primjene ultra i/ili mikrofiltracije u procesu pročišćavanja biodizela.

Published: March 2020

A 67-year-old man with a 3-year history of dyspnea on exertion arrived to our institution with discontinuous palpitations and short breath. He was diagnosed with congenital coronary artery fistula (CAF). Angiography revealed 3 giant aneurysmal formations and coronary artery calcification. We report a case of successful repair of CAF with a giant coronary aneurysm by closing the orifice and resecting the aneurysm and reconstructing the left coronary artery. The surgical procedure included closure from within a vessel dilated by aneurysm and excision of the aneurysm. We were able to completely obliterate the fistula and preserve the normal blood flow through the coronary arteries post operation. The postoperative course was eventful, but the patient was discharged home. The patient was doing well at his 28-month follow-up visit.
A nova revolução copernicana: quando o Eu, o Outro e o Todo são outros
Authors: Garcia Luis Fellipe
Published: March 2020

No prefácio da segunda edição da Crítica da razão pura, Kant propõe uma revolução metodológica em Filosofia similar à revolução copernicana: ao invés de tratar o observador como um centro fixo em torno do qual os objetos gravitam, pensá-lo antes como um móvel cujos movimentos cognitivos permitiriam explicar fenômenos anteriormente inexplicáveis. Alguns filósofos contemporâneos sugerem que essa revolução deva ser realizada de um ponto de vista geográfico, pois os problemas fundamentais da Filosofia parecem gravitar todos em torno do mesmo centro fixo, o qual não é confrontado à fragilidade de sua posição geográfica contingente, o centro europeu. O objetivo deste artigo é reconstruir as linhas gerais dessa nova revolução copernicana como um procedimento de reavaliação de três vetores centrais do saber: o Eu, o Outro e o Todo.
La razón evaluadora entre temporalidades discontinuas y repartición de lo sensible. Del culto evaluacionista a una educación indisciplinada
Authors: Giuliano Facundo
Published: March 2020

Este ensayo se plantea como un montaje intertextual cuya metodología filosófica-estética apuesta a problematizar la configuración de temporalidades, regímenes escópicos y políticas de lo audible en las visiones hegemónicas del presente que configuran los dispositivos pedagógicos siempre atravesados por la razón evaluadora. Esto en busca de gestualidades ético-políticas cuya radicalidad dé lugar a temporalidades más igualitarias, que las supuestas por el tiempo productivo y cronológico de la escuela moderna/colonial. En este sentido, dicho planteamiento supone una dimensión crítica de la razón evaluadora que se discutirá a partir de la detección de algunos problemas y líneas de análisis como: (1) la configuración del evaluacionismo y sus valores como culto capitalista que coloniza la escuela; (2) la no-experiencia de la evaluación y las temporalidades del juicio, la acusación y la condena; (3) el tiempo evaluacionista que recicla la confesión en las nuevas prácticas de autoevaluación con sus respectivas operaciones de auto-culpabilización/calumnia y “responsabilización”.
Juan Carlos Scannone y el debate con la filosofía inculturada
Authors: Villanueva Barreto Jaime
Published: March 2020

Al plantear la necesidad de renovar la filosofía latinoamericana, el P. Juan Carlos Scannone (1931-20019) destacó la importancia de la noción de inculturación. Tal concepto refiere a la integración que se produce entre las múltiples culturas en términos de igualdad y respeto. Para que se produzca la inculturación se requiere que las características propias de la cultura sean recogidas por una nueva filosofía. El modelo de inculturación que propone Scannone emerge de las propias experiencias culturales de los pueblos y es aplicable a la filosofía y la teología latinoamericanas para que puedan tener rasgos característicos de las culturas a las que pertenecen. La categoría fundamental de la filosofía inculturada propuesta por Scannone es la de la sabiduría popular que media entre la cultura, la religiosidad, los símbolos y las narrativas populares, por un lado, y el pensamiento filosófico, por el otro. El objetivo de este artículo es mostrar la imbricación entre la sabiduría popular y su raigambre en el mundo de la vida, ya que con ella se construyen los símbolos culturales que determinan el comportamiento e historia de los pueblos. Para esto procederemos en cinco tiempos: primero, a modo de introducción, expondremos el papel que juega la inculturación en la filosofía latinoamericana. En segundo lugar, veremos la aplicación de esta en la teología, en la que ya se empieza a esbozar la relación de la sabiduría popular con el mundo de la vida en la producción de símbolos. En tercer lugar, examinaremos la crítica de Scannone a la noción misma de inculturación y su propuesta de un “nosotros”, un “estar” y la “mediación simbólica”. En un cuarto momento, veremos cómo en la dimensión ética e histórica de la filosofía confluye la imbricación entre estas nociones y el mundo de la vida popular del que nos habla Scannone. Finalmente, a partir de una aproximación descriptiva, primero, y reconstructiva, después, de la propuesta scannoniana de la inculturación, proponemos una suerte de teoría del reconocimiento que hunde sus raíces en el mundo de la vida o “nosotros inclusivo”.
El sistema de la ciencia: la filosofía no disyuntivista de Hegel
Authors: Hernández Rodríguez Juan Camilo
Published: March 2020

En este texto me propongo elaborar un esbozo general de los principales conceptos clave del Sistema de la ciencia de Hegel: el Absoluto, la determinación, la distinción entre realidad, existencia y ser, y la relación entre lo finito e infinito. Mi propósito en este texto es ofrecer los rasgos fundamentales del sistema metafísico hegeliano a partir de su contexto previo, de su obra y de una lectura de bicondicionalidad —y no de identidad— de dichos conceptos, relaciones y estructuras como no-disyuntivistas. Finalmente, a partir de dicha exposición evaluaré si las principales críticas que se le han hecho a Hegel son o no justificadas y si son o no un problema serio para su proyecto metafísico: el Sistema de la ciencia.

BEAF (Boundary Element-Associated Factor) was originally identified as a Drosophila melanogaster chromatin domain insulator-binding protein, suggesting a role in gene regulation through chromatin organization and dynamics. Genome-wide mapping found that BEAF usually binds near transcription start sites, often of housekeeping genes, suggesting a role in promoter function. This would be a nontraditional role for an insulator-binding protein. To gain insight into molecular mechanisms of BEAF function, we identified interacting proteins using yeast two-hybrid assays. Here, we focus on the transcription factor Serendipity δ (Sry-δ). Interactions were confirmed in pull-down experiments using bacterially expressed proteins, by bimolecular fluorescence complementation, and in a genetic assay in transgenic flies. Sry-δ interacted with promoter-proximal BEAF both when bound to DNA adjacent to BEAF or > 2-kb upstream to activate a reporter gene in transient transfection experiments. The interaction between BEAF and Sry-δ was detected using both a minimal developmental promoter (y) and a housekeeping promoter (RpS12), while BEAF alone strongly activated the housekeeping promoter. These two functions for BEAF implicate it in playing a direct role in gene regulation at hundreds of BEAF-associated promoters.

Abstract The pomegranate fruit exhibits medicinal properties due to the nutraceutical characteristics, especially of its peel. The objective of this study was to analyze the influence of different drying methods on the physicochemical and biochemical characteristics of the pomegranate peel. The experiment was conducted in a completely randomized design in subdivided plots: 4 (full sun [SUN], drying chamber [DC] at 60 ± 2 °C, cold chamber at 10 °C and 60% relative humidity (RH) [CC], solar dryer [SD]) × 2 (presence or absence of 1% ascorbic acid [AA]). The analyzed variables were mass loss, index of drying heterogeneity (IHD), Hue internal (LI, CI, HI) and external (LE, CE, HE) angles, as well as Chroma, of the peel, and finally, total phenolic compound (TCFT) and flavonoid (TFLA) content. DC treatment led to the shortest drying time, followed by SUN and SD treatments. A reduction in IHD was observed with respect to time, which was more pronounced in DC treatment. CC treatment produced a more positive response both for LI and LE. TCFT and TFLA content produced from DC treatment presented an interaction effect, which was reduced by the application of AA. On the other hand, dehydration without the application of AA in the drying chamber or in full sun resulted in the best responses in TCFT and TFLA content.
A causa final nas Disputas metafísicas de Francisco Suarez
Authors: Cezar Cesar Ribas
Published: March 2020

Resumo: Nas Disputationes metaphysicae (disp. 23 e 24) Francisco Suarez tenta mostrar que a causa final não é uma projeção do intelecto humano, mas algo real nas próprias coisas e que sem ela não é possível dar uma explicação satisfatória dos fatos observados na experiência. Ele mostra como a causa final age no ser humano, em Deus, nos chamados ‘agentes naturais’ e no universo como um todo. De fato, a causa final supõe a existência de algo capaz de conhecer um fim e de direcionar suas ações para ele. Mas isto não significa que o fim está totalmente ausente das operações dos ‘agentes naturais’, nem que a explicação teleológica nunca faça sentido para eles. Sob certo aspecto há intencionalidade mesmo nas operações dos entes não-racionais, pois toda a natureza está submetida à ação e à racionalidade divina.
Heidegger e Agostinho: o fenômeno da Tentatio e a historicidade do si (Selbst) na apropriação fenomenológica do livro X das Confissões
Authors: Santos Bento Silva
Published: March 2020

Resumo: O artigo trata do fenômeno da cura segundo a apropriação fenomenológica do livro X feita por Martin Heidegger no curso friburgense intitulado Augustinus und der Neuplatonismus (SS1921). Pretendemos apresentar o fenômeno da tentação e a historicidade do si: segundo a apropriação genuína do ser da vida de Agostinho, a “tentatio” (Versuchung) se torna expressão da mobilidade da existência histórico-atuativa, que jamais pode ser compreendida como “quietude”. É a vida mesma que, assumida em sua totalidade, representa uma “tentação”, uma provação - entendida em sentido ontológico-existencial - na medida em que indica o “como” (Wie) da atuação da facticidade. Na procura deste “como” originário surge a interrogação fundamental do que vem a ser a vida para si mesma: quaestio mihi factus sum (fiz de mim mesmo uma questão). Descortinamos na perda de si do “eu sou” o processo da temporalização como deformitas, como o defluxus na distração, como a queda no “inautêntico”. Com base nesta apropriação contemporânea do ser da vida de Agostinho chegaremos ao âmago do fenômeno da cura, compreendendo o curare como caráter fundamental da vida fática e reconhecendo na procura de Deus a constituição da facticidade e da cura de si que nesta procura se expressa.
A harmonia entre razão e oração no pensamento de Anselmo de Aosta
Authors: Vasconcellos Manoel
Published: March 2020

Resumo O presente artigo busca analisar uma das orações elaboradas por Anselmo de Aosta (1033-1109), mais precisamente, a Oração a São Nicolau, procurando mostrar como é possível encontrar, refletidos na prece, aspectos relevantes da produção filosófico-teológica do autor, sobretudo, em relação à situação do homem, marcado pelo pecado, uma vez que abandonou a retidão da vontade. Na prece, bem como em sua obra especulativa, Anselmo examina a situação do homem pecador, diante da graça e misericórdia divinas. Almejamos ressaltar a existência, na obra anselmiana, de uma harmoniosa relação entre oração e trabalho especulativo, em conformidade com o ideal beneditino do ora et labora.
IS COMMONALITY IN LIQUIDITY A PRICED RISK FACTOR?
Authors: SILVA JÚNIOR CLÁUDIO P. , MACHADO MÁRCIO A. V.
Published: March 2020

ABSTRACT Purpose: Analyze if the commonality in liquidity is priced and its relation with the stock return in the Brazilian stock market. Originality/value: Due to the shortage of papers about the effects of commonality in liquidity in the Brazilian financial literature, this paper provides knowledge development about commonality in liquidity effect for the investor, investigating whether an investment strategy in the most sensitive assets to systematic variations of liquidity is attractive for investors, consistent with the risk-return trade off. Design/methodology/approach: In order to identify the effect of commonality to investors, we opted to use portfolios. Using companies listed on B3 as a sample, we estimated regressions developed in the time series from January 2007 to December 2015. Findings: We found that the commonality is a phenomenon present in the Brazilian stock market and their highest values were concentrated in periods of international financial crises. In addition, using portfolios, we observed a premium of 4.165% per month for the commonality in liquidity, although not statistically significant. Finally, we found that the commonality in liquidity is a priced risk factor and when we exposed it to other risk factors we found that the liquidity risk factor was able to partly capture it.

ABSTRACT Studies related to water sorption in seeds are essential for the design and optimization of storage systems. The objective of this research was to determine and model the adsorption isotherms and calculate the latent heat of water vaporization, differential enthalpy and entropy, the isokinetic theory and Gibbs free energy for ‘Cumari-do-Pará’ pepper seeds. The equilibrium moisture contents were obtained by the static gravimetric method at temperatures of 30, 35 and 40 °C and water activities between 0.290 and 0.900 (decimal). The Chen-Clayton model is the one that best represents the water adsorption isotherms in ‘Cumari-do-Pará’ pepper seeds under the studied conditions, with 9.94% mean relative error, 0.40 mean estimated error and random distribution of residuals. The latent heat of vaporization ranged from 2,555.669 to 3,162.180 kJ kg-1. The enthalpy, entropy and Gibbs free energy increase with the reduction in the equilibrium moisture content of the seeds. The isokinetic theory is valid for the adsorption process.
Depressive disorders in the elderly and dementia: An update

ABSTRACT The relationship between depressive disorders in the elderly and dementia, particularly Alzheimer’s disease (AD), is highly complex. While the nature of this relationship is still a matter of debate, differential diagnosis and treatment remain a great clinical challenge. We review recent findings on the conundrum of depressive disorders in the elderly and AD. There is a biological continuum between depressive disorders in the elderly – or at least a subgroup of them – and AD. While elderly subjects with depression and patients with AD exhibit higher circulating levels of pro-inflammatory molecules and lower BDNF than matched controls, CSF levels of Aβ42 can discriminate AD from depressive disorders in the elderly. The role of antidepressant treatment as a strategy to minimize the risk of AD remains to be established.

ABSTRACT Dementia is a chronic neurodegenerative disease and Alzheimer’s disease (AD) is the most prevalent type. Objective: To describe the drug monitoring of patients enrolled in a Clinical Protocol and Therapeutic Guidelines of Alzheimer’s Disease (PCDTDA) in Brazil. Methods: A descriptive study based on interviews conducted in 2017 was performed. Patients diagnosed with Alzheimer’s disease (AD) enrolled on the PCDTDA were included. The variables assessed were age, sex, time since diagnosis, clinical parameters of Mini-Mental State Exam (MMSE) and Clinical Dementia Rating (CDR), drug therapy used and AD drug collection. Results: The drug monitoring of 143 patients was evaluated. Observing the requirements of the screening tests for patient enrolment on the PCDTDA, all patients had scores for at least one MMSE and CDR assessment at protocol admission. None of the patients underwent the first reassessment of the effectiveness of AD drug therapy or the semiannual reassessment. Conclusion: Although PCDTDA provides the best evidence of AD treatment, the data showed failures in the monitoring of the effectiveness of AD drug therapy at dispensing.

ABSTRACT Mild cognitive decline is a feared aspect of aging associated with frailty experienced by individuals. Objective: To determine the number of elderly people with mild cognitive impairment (MCI); to determine the relationship of sociodemographic and clinical variables by group of individuals with or without MCI and to determine the relationship between MCI assessed by 6CIT and the cognitive domains assessed by the MoCA. Methods: A correlational study was conducted of 44 elderly individuals attending a day-care center or residing in a care home, with an average age of 88.9 ± 8.8 years who answered a structured interview collecting sociodemographic and clinical data. Results: The elderly living at home had higher average body mass index and number of pathologies than those living in an institution for the elderly (p < 0.01). 63.6% of the elderly did not have MCI, and no differences were found between residential settings. The comparison between 6CIT and MoCA yielded differences in the general domain and in visual, attention, abstraction and, orientation subdomains. Conclusion: Cognitive stimulation interventions should be optimized according to the residential setting at the level of comorbidities and nutrition.
Biomarkers in Alzheimer’s disease: Evaluation of platelets, hemoglobin and vitamin B12
Authors: Santos Gustavo Alves Andrade dos , Pardi Paulo Celso
Published: March 2020

ABSTRACT Currently, the most likely hypotheses as the cause of Alzheimer’s disease are deposition of amyloid beta peptide in the cerebral cortex and hyperphosphorylation of Tau protein. The diagnosis of Alzheimer’s disease is based on the exclusion of other diseases, behavioral assessments, and blood and imaging tests. Biotechnology has created interesting perspectives for the early detection of Alzheimer’s disease through blood analysis, with special attention to platelets, hemoglobin and vitamin B12. Objective: To evaluate the concentrations of platelets, hemoglobin and vitamin B12 in the blood of older adults with and without dementia of Alzheimer’s disease. Methods: A case-control study involving 120 individuals was conducted, seeking to establish a correlation between changes in platelet, hemoglobin and vitamin B12 concentrations in patients with confirmed AD and in individuals in the inclusion group without AD. The study met the established ethical requirements. Results: Hemoglobin and platelet levels were statistically lower in patients with AD. The biochemical evaluation in AD patient and healthy groups for vitamin B12 showed a decrease in the levels of this compound in patients with AD. Conclusion: We demonstrated the feasibility of the use of blood biomarkers as predictive markers for the diagnosis of AD.
