Authors: Guedes Kaline Abrantes , Tinem Nelci 
Published: April 2021

O objetivo deste artigo é apresentar resultados preliminares alcançados em uma pesquisa sobre inventários de arquitetura moderna no Brasil a partir da análise de suas fichas de registro. Esses resultados fazem parte de uma tese de doutoramento e têm como objetivo, por sua vez, refletir sobre os fundamentos teóricos e os instrumentos que orientam a prática e a produção dos inventários. Estão sendo identificados, localizados, coletados e analisados variados inventários de arquitetura moderna produzidos no País e interessa discutir: qual seria o lugar a partir do qual se instauram os métodos para elaboração dos inventários? Quais documentos e questões têm sido privilegiados e negligenciados? Quais as especificidades de um inventário da produção moderna – arquitetura experimental que propunha romper paradigmas e utilizava avanços tecnológicos no limite? Qual a extensão da importância dos modelos difundidos pelo Docomomo e como estão sendo contempladas as discussões e estudos teóricos recentes sobre temas correlatos? Qual o papel do inventário moderno e como esse instrumento de preservação e documentação pode contemplar as peculiaridades dessa produção para atuar na sua preservação? Faz-se necessário pensar e repensar o papel dos inventários na escrita da história e seus objetivos e métodos, de forma a avançar na produção do conhecimento, avaliando-o constantemente, enfrentando novos problemas, incluindo novos questionamentos e alimentando as desconfianças.

Published: April 2021

Abstract
The awareness of the widespread influence of hypertension on various organ systems is ever increasing. Changes associated with this disease can be observed in the heart, brain, kidneys, but also the organ of vision. These usual microvascular changes are defined as hypertensive retinopathy. During a funduscopic examination, abnormalities such as narrowing of arterioles, symptoms of arteriole and vein intersection, cotton wool spots, intra-retinal exudates, retinal haemorrhages, and in severe cases even swelling of the optic disc and macula. This review presents an overview of the changes at the fundus of the eye that may occur in patients with hypertension, as well as problems with the classification of hypertensive retinopathy over the years, and the development of diagnostic methods in ophthalmology and fundoscopic imaging.

Abstract
Cell encapsulation utilizing biodegradable material has promising outcomes for tissue engineering. From a long time ago, alginate has been generally utilized for drug delivery, cell transplantation and as a scaffold in biomedical applications. The aim of this study was the comparison of cell viability in the presence of two polymerizing ions: Ba2+ and Ca2+ to improvement the quality of alginate scaffold. For this purpose, WJMSCs after three passage were encapsulated in alginate scaffold in the presence of Ba2+ and ca2+. Cell viability was evaluated by WST-8 assay kit after 24, 48 and 72 hours. The results showed that encapsulated cells in the presence of Ca2+ had more viability than Ba2+. It was also found that using the WST-8 assay kit is a convenient and fast method for evaluation the viability of cells. It can be claimed that Calcl2 polymerizing solution provides more favorable conditions for cell viability compared to Bacl2 solution.

Authors: Karakurt Serdar , Kandir Sinan , Gökçek-Saraç Çiğdem 
Published: April 2021

Abstract
The present study’s objective is to clarify the molecular mechanisms of tannic acid effects on the viability of human colorectal carcinoma (CRC). Tannic acid is stable for up to 48 h and is localized in both cytoplasm and nucleus. It dose-dependently inhibited the viability of CRC cell lines; SW-620 and HT-29 with IC
50 values of 7.2 ± 0.8 and 37.6 ± 1.4 µmol L–1. Besides, metastatic, invasive, and colony formation properties of CRC cells were significantly inhibited following the tannic acid treatment (p < 0.001). Tannic acid has been found to modulate enzyme, protein, and gene expressions of NQO1 in different levels and the upregulation of protein/gene expressions of p53 (p < 0.001), which leads the cells to trigger apoptosis. In conclusion, the present in vitro study may supply a significant background for in vivo studies in which the molecular mechanisms of antioxidant and chemopreventive activities of tannic acid will completely clarify.
Computation of SIFs for cracked FGMs under mechanical and thermal loadings
Authors: Ait Ferhat Yazid , Boulenouar Abdelkeder 
Published: April 2021

AbstractThe objective of this study is to present a numerical modeling of mixed-mode fracture in isotropic functionally graded materials (FGMs), under mechanical and thermal loading conditions. In this paper, a modified displacement extrapolation technique (DET) was proposed to calculate the stress intensity factor (SIFs) for isotropic FGMs. Using the Ansys Parametric Design Language APDL, the continuous variations of the material properties are incorporated by specified parameters at the centroid of each element. Three numerical examples are presented to evaluate the accuracy of SIFs calculated by the proposed method. Comparisons have been made between the SIFs predicted by the DET and the available reference solutions in the current literature. A good agreement is obtained between the results of the DET and the reference solutions.

Authors: Chamurliyski Plamen S. , Ivanova Albena M. 
Published: April 2021

Abstract
The purpose of this study is to evaluate the condition of a collection of Bulgarian common wheat varieties under ex situ controlled storage after a ten-year period. The studied materials are characterized by high vitality, without negative changes that will lead to the loss of original germplasm. The established moisture in the seeds is high for the purpose of controlled storage. When it rises above 12,5%, a decrease in the values of germination energy is observed. Higher control of initial moisture and germination is required prior to entering the seeds for storage under ex situ conditions.

Published: April 2021

Abstract
The interferon regulatory factor gene family encodes transcription factors with multiple biological functions, which include reproduction, cell differentiation and immunity. Interferon regulatory factor-5 (IRF-5) gene is involved in immune defence against virus, stress response, activation of type I interferon genes, cell differentiation and growth. This experiment was conducted to identify and characterise single nucleotide polymorphisms in exons 3, 4, 5 and 7 of IRF-5 gene in Nigerian local chickens. Exons 3, 4, 5 and 7 of IRF-5 gene were amplified and sequenced. Single nucleotide polymorphisms (SNPs) present in exons 3, 4, 5 and 7 of IRF-5 gene were identified and analysed using Clustal W, DnaSp and SNAP2 software packages. Four SNPs, rs317511101, rs312902332, rs315149141 and rs739389464, were identified in exon 3 of IRF-5 gene in all the three genotypes. Exon 4 of the gene was conserved while three of the SNPs (rs736423928, 170C>T and rs740736761) identified in exon 7 were shared among the three genotypes. Linkage disequilibrium of 1.00 existed between rs317511101 and rs315149141 polymorphisms identified in exon 3 of normal feathered and frizzle feathered chickens. Mutation rs740736761 identified in exon 7 had the highest polymorphism information content obtainable for any biallelic marker. Most of the SNPs identified in exons 3, 5 and 7 were synonymous and singletons which could not be used for association study. The study concluded that only haplotypes in exons 3 and 7 of IRF-5 gene can be used in marker-assisted selection when improving Nigerian local chickens.

Authors: Ndukwe Gloria I. , Chahul Habibat F. , Oodo Godwin 
Published: April 2021

Abstract
We report on the preliminary phytochemical screening of the methanolic extract of the aerial parts of Lepidagathis alopecuroides and its evaluation as a potential corrosion inhibitor for mild steel in aerated 1.0 M HCl by weight loss and linear polarization measurements. Weight loss measurements were conducted at 303, 313, 323 and 333 K. The results showed that L. alopecuroides inhibited the corrosion of mild steel in the acid solution with inhibition efficiency increasing with increase in the concentrations of the plant extract but decreased with increase in temperature. Linear polarization plots showed the plant extract to inhibit both the dissolution of the steel at the anode and the hydrogen evolution reaction (HER) at the cathode making it a mixed inhibitor. Temkin adsorption isotherms best modeled the adsorption of L. alopecuroides extract on the steel surface. From the values of the evaluated kinetic activation parameters in the study, the mechanism of physisorption is proposed for the adsorption of the plant extract on the steel surface.

Published: April 2021

Abstract
The levels of some heavy metals in spent engine oils and in the fingernails of auto-mechanics were studied. Engine oils and fingernails were collected from auto-mechanics who had practiced between ≤ 5 years, ≤ 10 years and ≤ 15 years in 3 auto-mechanic workshop clusters. Pb, Ni, V, Cd, and As levels were determined using Atomic Absorption Spectrophotometer. The mean levels of Pb, Ni, V and Cd in spent engine oils were 14.31, 2.25, 0.38 and 2.07 ppm respectively, and these far exceeded their permissible exposure limits. The mean levels of heavy metals in the fingernails of auto-mechanics who had practiced for ≤ 5 years, ≤ 10 years and ≤ 15 years were all considerably below their pathological thresholds. Thus, auto-mechanics in the study area are exposed to unsafe levels of Pb, Ni, V, and Cd, but no immediate threat of their toxicities in the study population exist. However, a progressive bioaccumulation of the heavy metals was observed with increase in years of practice.

Published: April 2021

Abstract
Ready-to-eat salads are becoming more and more popular. However, due to their ingredients, they represent a suitable growth environment for different microbes. In the prevention of foodborne diseases, hygienic food preparation and appropriate storage conditions are very important. During this study, ten different ready-to-eat salads were analysed for the presence of Listeria monocytogenes. Five different selective agar mediums were used for the enumeration and isolation of Listeria monocytogenes. The isolated bacterial strains were subjected to morphological and biochemical confirmation tests. The antibacterial effects of five different freshly squeezed vegetable juices (carrots, celery, beets, horseradish, and onions) and of five essential oils (dill, thyme, oregano, lemongrass, and sage) were determined against Listeria monocytogenes, Listeria innocua, and L. monocytogenes strains isolated from ready-to-eat salads. Based on the results obtained from fresh vegetable juices, carrot juice exerted the highest antibacterial effect, while the others showed no or slight inhibitory effect (horseradish, beets, onions) against Listeria species. Among the essential oils, thyme, lemongrass, and oregano showed the strongest antibacterial effect against the studied Listeria species.

Published: April 2021

Abstract

Pistacia atlantica has a lot of medical, pharmaceutical and economic benefits, and its variability shows its evolutionary potential. The objective of this study was to investigate morphological and micro-morphological variability of these trees within different ecological regions. This study offers a general description of sites, an analysis of morphological variability of twenty quantitative and qualitative parameters based on the impact of natural and artificial conditions, and leaf anatomical analysis. The results showed that the population exhibited heterogeneity in all parameters of the leaf related to changes in soil, density, climate and slope. Variability in nut size was also demonstrated which was due to the effects of climate, type of soil and topographic factors. The results of electron microscope scanning of leaf anatomy showed the existence of large micro-morphological variability between study sites.
New Ranking Functions for Interval-Valued Intuitionistic Fuzzy Sets and Their Application to Multi-Criteria Decision-Making Problem
Authors: Kokoç Melda , Ersöz Süleyman 
Published: April 2021

Abstract
Many authors agree that the Interval-Valued Intuitionistic Fuzzy Set (IVIFS) theory generates as realistic as possible evaluation of real-life problems. One of the real-life problems where IVIFSs are often preferred is the Multi-Criteria Decision-Making (MCDM) problem. For this problem, the ranking of values obtained by fuzzing the opinions corresponding to alternatives is an important step, as a failure in ranking may lead to the selection of the wrong alternative. Therefore, the method used for ranking must have high performance. In this article, a new score function SKE and a new accuracy function HKE are developed to overcome the disadvantages of existing ranking functions for IVIFSs. Then, two illustrative examples of MCDM problems are presented to show the application of the proposed functions and to evaluate their effectiveness. Results show that the functions proposed have high performance and they are the eligibility for the MCDM problem.
The Probabilistic Risk Measure VaR as Constraint in Portfolio Optimization Problem
Authors: Stoilov Todor , Stoilova Krasimira , Vladimirov Miroslav 
Published: April 2021

Abstract
The paper realizes inclusion of probabilistic measure for risk, VaR (Value at Risk), into a portfolio optimization problem. The formal analysis of the portfolio problem illustrates the evolution of the portfolio theory in sequentially inclusion of different market characteristics into the problem. They make modifications and complications of the portfolio problem by adding various constraints to consider requirements for taxes, boundaries for assets, cardinality constraints, and allocation of the investment resources. All these characteristics and parameters of the investment participate in the portfolio problem by analytical algebraic relations. The VaR definition of the portfolio risk is formalized in a probabilistic manner. The paper applies approximation of such probabilistic constraint in algebraic form. Geometrical interpretation is given for explaining the influence of the VaR constraint to the portfolio solution. Numerical simulation with data of the Bulgarian Stock Exchange illustrates the influence of the VaR constraint into the portfolio optimization problem.

Published: April 2021

Abstract
Student engagement is an essential device for deepening learning, achieving learning outcomes, developing competencies, and improving academic performance in education settings. It is widely receiving increased attention among various scholars and higher education leaders. However, there are increasing concerns about the academic performance of students in higher education settings. The application of statistical data analytics for mining student engagement datasets is a candidate strategy for discovering essential indicators associated with academic performance. However, widely used data analytic methods like principal component analysis are ineffective when most of the indicators captured are categorical, making them inappropriate for establishing the weighty academic performance indicators. This study’s objective was to investigate the application of multiple correspondence analysis to establish weighty student engagement indicators of academic performance. This study’s findings have indicated that higher-order learning and student-staff interaction are weighty indicators that relate student engagement to academic performance.

Published: April 2021

AbstractDesign principles of a novel Multifunctional Operation Station (MOS) using Augmented Reality (AR) technology (MOSAR) are proposed in this paper. AR-based design allows more ergonomic remote instrument control in real time in contrast to classical instrument-centered interfaces. Another advantage is its hierarchical software structure including multiple programming interpreters. The MOSAR approach is illustrated with a remote surgical operating station that controls intelligent surgical instruments. The implementation of the Operation Station (MOS) is based on the multiplatform open-source library Tcl/Tk, and an AR extension has been developed on a Unity platform, using Vuforia SDK.
