To date, the novel Corona virus (SARS-CoV-2) has infected millions and has caused the deaths of thousands of people around the world. At the moment, five antibodies, two from China, two from the U.S., and one from the UK, have already been widely utilized and numerous vaccines are under the trail process. In order to reach herd immunity, around 70% of the population would need to be inoculated. It may take several years to hinder the spread of SARS-CoV-2. Governments and concerned authorities have taken stringent measurements such as enforcing partial, complete, or smart lockdowns, building temporary medical facilities, advocating social distancing, and mandating masks in public as well as setting up awareness campaigns. Furthermore, there have been massive efforts in various research areas and a wide variety of tools, technologies and techniques have been explored and developed to combat the war against this pandemic. Interestingly, machine learning algorithms and internet of Things (IoTs) technology are the pioneers in this race. Up till now, several real-time and intelligent COVID-19 forecasting, diagnosing, and monitoring systems have been proposed to tackle the COVID-19 pandemic. In this article based on our extensive literature review, we provide a taxonomy based on the intelligent COVID-19 forecasting, diagnosing, and monitoring systems. We review the available literature extensively under the proposed taxonomy and have analyzed a significantly wide range of machine learning algorithms and IoTs which can be used in predicting the spread of COVID-19 and in diagnosing and monitoring the infected individuals. Furthermore, we identify the challenges and also provide our vision about the future research on COVID-19.
Cramér-Rao Lower Bounds of Model-Based Electrocardiogram Parameter Estimation
Authors: Fattahi Davood , Sameni Reza
Published: August 2021

Clinical parameter estimation from the electrocardiogram (ECG) is a recurrent field of research. It is debated that ECG parameters estimation by human experts and machines/algorithms is always model-based (implicitly or explicitly). Therefore, all estimation algorithms used in this context have performance bounds in terms of the achievable mean squared error, which are not exceedable. These bounds depend on the adopted data-model, the estimation scheme (least-squares error, maximum likelihood, or Bayesian), and prior assumptions on the model parameters and noise distributions.

In this research, we develop a comprehensive theoretical framework for ECG parameter estimation and derive the Cramér-Rao lower bounds (CRLBs) for the most popular signal models used in the ECG modeling literature, namely functional expansions (including polynomials) and sum of Gaussian functions. The developed framework is evaluated over real and synthetic data for three popular applications: T-to-R wave ratio estimation, ST-segment analysis and QT-interval estimation, using the state-of-the-art estimators in each context. The proposed framework and the derived CRLBs provide practical guidelines for the selection of data-models, sampling frequency (beyond the Nyquist rate), modeling segment length, number of beats required for ECG beat averaging, and other factors that influence the accuracy of ECG-based clinical parameter estimation.

Antioxidant and hypoglycemic activities of various solvent fractions of methanol extract of Terminalia alata Heyne ex Roth trunk-bark
Authors: Nguyen Quang Vinh , Hung Pham Van , Nguyen Anh Dzung
Published: August 2021

The antioxidant and hypoglycemic capacities of various solvent fractions from the trunk-bark methanol extract of Terminalia alata Heyne ex Roth (T. alata) were investigated. The DPPH radical scavenging assay was used to evaluate the antioxidant activity, and the methods for determination of digestive enzymes inhibitory activity and fasting blood glucose reduction capacity in diabetic rats were used to determine the hypoglycemic activity of the extract fractions. The results indicated that higher total phenolics content was measured with increasing polarity of extraction solvent and DPPH radical scavenging activity coincided with phenolics content. Ethyl acetate fraction (EAF), n-butanol fraction (BF), and water fraction (WF) were obtained. They possessed α-amylase inhibition with the IC50 values of 0.056 ± 0.001, 0.138 ± 0.005, and 0.022 ± 0.001 mg.mL-1, respectively, which were lower than acarbose (IC50 = 0.154 ± 0.02 mg.mL-1). In contrast, IC50 values of α-glucosidase inhibitory activities of these fractions were higher than those of acarbose. In addition, these fractions also lowered fasting blood glucose concentrations in streptozotocin induced diabetic rats at a dose of 200 mg.kg-1 bw (body weight) without inducing body weight loss, which was not observed when treating with acarbose. The EAF and WF of trunk-bark of T. alata are recommended as potent sources for further research on antioxidant and hypoglycemic activities.

The objective of this study was to evaluate the in vitro effectiveness of membranes developed with pure chitosan and chitosan in a mixture with glycerol-honey against gram-negative bacteria isolated from skin ulcers. The membranes were prepared by the solvent evaporation technique. The identification and antibiotic sensitivity of microorganisms were determined in microplates, and in vitro tests were developed by the agar diffusion technique. The most frequently isolated microorganism was Escherichia coli with 43.75 % prevalence. All membranes showed antimicrobial effects by direct contact against Proteus mirabilis, Escherichia coli, Enterobacter aerogenes, Pseudomonas aeruginosa, Klebsiella pneumoniae and Morganella morganii. Antibiograms showed that most of these microorganisms are multi-resistant to antibiotics. All of this suggests that chitosan-based membranes are a safe alternative for the treatment of infected cutaneous ulcers compared to traditional antibiotics. The outcomes of this study confirm that membranes made of a biodegradable polymer, such as chitosan have activity against multidrug-resistant gram-negative bacteria that grow in infected skin ulcers.

Published: August 2021

The main goal of the present study was to determine optimal conditions for the extraction of oil with high added value by cold pressing technique. Namely the feeding conditions of the Opuntia ficus-indica (L.) Mill. (OFI) seeds, as well as the definition of the manipulable variables of the Kern-Kraft 20 press were specified. These specifications combine HAZOP (Hazard and Operability) analysis and experience plan to find out correlation between yield and oil quality with the pressure, temperature, nozzle diameter, residence time, pressing speed while considering high hardness level of the seed under study. The seed oil extracted according to the proposed approach was highly unsaturated where linoleic acid is the main fatty acids (60.42 % of total fatty acids), followed by oleic acid (21.65 %), palmitic acid (12.24 %), and stearic acid (3.88 %), respectively. Furthermore, it is worth mentioning that beta-sitosterol and gamma-tocopherol were the principal components of sterols and tocopherols representing 67.56 % of total sterols and 330 mg.kg-1 of total tocopherols. The proposed approach applied to prickly pear seeds had preserved the tocopherol fraction (796.70 mg.kg-1 of total tocopherols) about two times more than other cold-pressed seed oils approaches. Based on trial-and-error conditions, no additional operating problem even has been reported with a seed of high level of hardness. Seed should be introduced with a humidity level of 10 % without grinding. Moreover, no heating should be supplied and an optimal pressing speed of 30 and a nozzle diameter of 15 mm.

Published: August 2021

The effectiveness of the freshwater bivalve Batissa violacea depuration was tested in closed and open water circulatory system over a 48 h period. The closed circulatory system included a sand biofilter. Microbial levels were assessed every 4 h using Total Aerobic Plate Count (TPC) for heterotrophs and Most Probable Number (MPN) for coliforms. TPC and coliform loads in bivalve tissue reduced rapidly to low and undetectable levels in a closed circulatory system while open system showed a slower reduction. Both TPC and coliform loads remained above detectable levels throughout the depuration period. Closed system showed similar patterns of logarithmic reduction of TPC and coliforms in all cases with R2>0.95 and p<0.001. Similar results were observed for tank water however, reduction of TPC and coliforms were slower. Biofilm formation was observed in the interior walls of the aquarium tanks over 48 h in all cases. Physicochemical parameters did not show any significant change. The reduction in TPC and coliform load in B. violacea suggests that biofilter in a closed water circulatory system is a simple, cost-effective, water conserving and effective way to significantly reduce the spoilage and coliform bacterial load that is accumulated in the clams.

A crop growing in the right quantity and quality can only be secured if nutrients are provided in an adequate quantity and available form. Copper (Cu) has primary importance among microelements in growing winter wheat. Lack of Cu hinders nitrogen uptake by plants. Therefore, increasing bioavailability is important in crop production. It has been conducted successful foliar fertilisation experiments with Tetraamminecopper(II) sulphate for several years. The efficiency of the applied compound was enhanced by the application of a retarded nutrient-supply. To secure retardation, ion exchange was carried out in NaA type synthesized zeolite with Tetraamminecopper(II) sulphate. Structure of Tetraamminecopper(II) sulphate, and zeolite ion-exchanged by copper-tetraamine was analysed with a derivatograph and X-ray diffraction. Derivatograph analyses revealed heat stability. X-ray diffraction analyses revealed that copper-tetramine ions exchanged a significant part of the sodium ions of zeolite in ion exchange.

The effect of solutions of cadmium telluride quantum dots (CdTe QD) as powerful cytotoxic effectors was investigated using a standard Allium cepa L. test system. The diameters of synthesized CdTe QD derived from the optical data varied within 3 – 4 nm. Toxicity of experimental solutions of CdTe QD at the organism level were evaluated by measuring biomass growth of onion roots and cytotoxic influence was estimated based on proliferative activity of root meristem cells. All of CdTe QD experimental solutions in concentration 10 µM significantly inhibited the growth of Allium cepa L. roots, proliferative activity, and total dehydrogenase activity. Relation between the QDs size and their phytotoxicity was not found. However, the highest inhibiting impact was for QDs solution with a nanocrystals size of 3.5 nm. Their ability to penetrate into cells and interact with their intracellular components may cause inhibiting mitosis without fixed clastogenic and aneugenic effects. Solutions of CdTe QD at a given concentration can be considered as potent cytostatic agents for plant cells with antimitotic properties.

The search for antimicrobial drug of high bio-efficacy not prone to multiple microbial resistance has been on the rise in recent time. This study focused on the preparation, characterization and antimicrobial evaluation of Schiff functionalized HNO3 activated plantain peel and rice husk biochar against five pathogenic bacteria. The activated rice husk and plantain peel biochar were characterized using Braunauer-Emmett-Teller, X-ray diffraction and Fourier transform infra-red spectroscopy. Based on the result, the activated rice husk and plantain peel biochar were amorphous and crystalline respectively with pore surface area and pore size for activated rice husk and plantain peel biochar as 9.369 and 27.32 (m2.g-1) and 8.790 and 16.65 (cc.g-1), respectively. The Fourier transform infra-red spectroscopy result indicated bonds, such as –OH, C=O and –N-H, where actual chelation and electrostatic attraction mechanism are prevalent responsible for antimicrobial potency. The cell bioactivity was hampered due to permeation of the biocidal agents, cell membrane disruption and generation of reactive oxygen species enhanced by conjugation of Schiff base based biochar to the microbial cell wall leading to death of microbes. The ease of Schiff base release and reusability of the nanocomposite favors the product as an efficient, low cost, effective and promising nanocomposite for decontamination of bacteria infested media.

Mining activities in the areas Krompachy and Rudňany-Markušovce were focused on mining and processing of copper and mercury ore and left harmful effects on the region of Eastern Slovakia. The aim of this study is using different screening methods (XRF, Phytotoxkit and earthworm bioassays) for environmental risk assessment of metal-contaminated areas. Elemental analysis by X-ray fluorescence spectrometry indicated severe pollution of studied soils by Cu, Ni, As and Hg, which exceeded limit values. Significant positive correlation is found between Pb and Zn occurrence in the agricultural soil from Krompachy: Kluknava, and for the contents of particular metals in soil from permanent grass vegetation in Kolinovce locality, namely between Pb and Ni, Pb and Zn, and between Hg and Zn contents. A 7-day bioassay and avoidance test with the Dendrobaena veneta was used to assess the environmental risk of heavy metals in soils. The earthworms mortality was very little influenced by metals in Krompachy soils, but rather affected by Rudňany soils tailing. Phytotoxkit results for soils from Krompachy showed inhibition in germination by 32 % and 29 % for Sinapis alba and Lepidium sativum, respectively. Results of the average percentage of growth inhibition by Lepidium sativum was 28 % and 24 % for Sinapis alba. On the other hand, soil samples from Rudňany tailing showed 56 % of germination inhibition by Sinapis alba, and 49 % for Lepidium sativum, respectively. Results of the average percentage of grow the inhibition by Lepidium sativum was 48 %, and 52 % for Sinapis alba Rudňany tailing soils. The significant results (P < 0.05) of the avoidance percentages of Dendrobaena  veneta for tested soils were within the range 80 – 100 % in soils Rudňany-Markušovce tailing after 48 h. The variable toxicity of contaminated soils demonstrated the efficiency and usefulness of the Phytotoxkit and earthworm bioassays as a useful tool for evaluation of soil ecotoxicity. The results supported the expected negative impact of the soil samples on the region Eastern Slovakia.

Published: August 2021

In this study, surface modification of hydroxyapatite (HAp) by grafting polycaprolactone (PCL) is described. This method is carried out into two steps: (1) A treatment of HAp powder with a mixture of tetraorthosilicate (TEOS) and 3-aminopropyl-etriethoxysilane (APTES) to introduce amine groups and enhance nucleophilicity of surface functionalities; (2) Initiation of the Ring Opening Polymerization (ROP) of the ε-caprolactone (CL) in the presence of the silanized HAp. Moreover, the impact of the reaction time (24, 48 and 72 h) on the grafting amount of PCL is performed. The results of FTIR analysis confirmed the presence of carbonyl groups on the silanized HAp, providing evidence of grafting of PCL on the HAp surface. WAXS pattern showed no formation of a secondary phase after surface modification and the crystallinity is preserved. SEM/TEM analysis revealed a homogenous surface powder composed of irregular nanoscale crystals. TGA analysis indicated the dependence of PCL graft amount on the reaction time. Finally, the effect of surface modification on HAp/PCL nanocomposites morphology was investigated.

Published: August 2021

The leaching of lithium from lepidolite using the filamentous fungus Aspergilluss niger was examined. Two mechanisms were suggested – biochemical using citric acid as the main bioleaching agent and biomechanical through hyphae penetration confirmed by XRD and SEM analyses. The bioleaching processes were conducted at various glucose concentrations (5 – 20 g.L-1). The higher glucose concentration was, the higher Li bioleaching was observed. Li accumulation by fungal biomass played an important role in Li solubilisation from lepidolite. Totally, 11.5 mg of lithium were recovered from 1 kg of lepidolite by combination of bioleaching and bioaccumulation processes. As a result of bioleaching, the formation of new silicate phase of SiO2 was detected. According to the results, fungal bioleaching of Li from lepidolite can be a perspective way of Li recovery from hard-rock ores.

The promotional efforts are need to be more fruitful and focused, therefore imperative to understand the conceptual advertising literacy level of the targeted child consumers. In order to reveal the related facts, the study examines the conceptual advertising literacy level of children in India. In a computer assisted survey of 392 children between the age brackets of 8-12 years, the researchers examine their ability of advertising recognition, understanding of advertising selling intent and understanding of advertising persuasive intent regarding brand promotion efforts. Results confirm that advertising recognition and understanding selling intent is high in children but children do not acquire a clear understanding of advertising persuasive intent until the age of 9-10 years. Furthermore, children’s understanding of advertising’s selling intent emerges before their comprehension of its persuasive intent.

El contenido del artículo tiene como finalidad esbozar un planteamiento donde se dimensionan elementos conceptuales y contextuales sobre el problema de las violencias y particularmente de la violencia de género hacia las mujeres indígenas. Violencia hacia las mujeres: recuperando la voz de la mujer indígena La violencia hacia las mujeres ha ido en aumento y no es privativo de un tipo de comunidad en lo específico, es un asunto que trastoca el ámbito familiar, social y cultural, fundamentalmente. Recurrir a los resultados de estudios e investigaciones en materia de violencia, permite procesos de reflexión, comprensión y análisis del problema, toda vez que aportan mayores elementos para la interpretación y la posibilidad de repensar en el diseño de estrategias que puedan contribuir a la definición de acciones para la prevención y la erradicación de un problema tan complejo que cada vez se agudiza en la sociedad mexicana. Se recupera la voz de la mujer indígena a través de la entrevista, que se constituye en una técnica que posibilita rescatar el pensar, sentir y decir de una mujer indígena triqui, que desde su perspectiva cultural y de los usos y costumbres del entorno en el que se desarrolla cotidianamente, percibe el problema y le asigna su propia interpretación.

Ver el contexto en el que se desenvolverá el trabajo social profesional en la próxima década, es sin duda ofrecer este espacio como el ámbito de las políticas sociales destinadas principalmente al desempeño de habilidades a fin de proporcionar atención de calidad a los adultos mayores y, ante el desarrollo físico propio, el desgaste mental y desgaste de los años, hemos de asumir la necesidad de crear entornos favorables. Una vida fácil para integrarse, no sólo para aquellos que disfrutan de un servicio de seguridad social a través de la recepción de la pensión o jubilación, sino en general para todos en el área de salud, educación, recreación y cultura, con el fin de integrar la sociedad de la información y la comunicación a través del uso de las nuevas tecnologías, de ahí la necesidad de profesionales de Trabajo Social para desarrollar habilidades laborales.
La mujer en la ciencia

Una de las grandes transformaciones de la educación en los últimos años se ha dado en el nivel superior, donde la presencia femenina ha tenido una progresión sostenida. Pocos son los cambios sociales que muestran el ritmo de crecimiento de la población femenina en las universidades; incluso su creciente incorporación en el sistema educativo pasó prácticamente inadvertida durante muchos años. Al tiempo que se desarrolla la instrucción femenina en el nivel superior se transforma su significado: en la actualidad, el paso de las mujeres por la universidad ya no tiene un valor meramente doméstico. Por el contrario, las mujeres se incorporan a los estudios superiores con nuevas miras, buscando ejercer sus conocimientos en los espacios públicos y en el mercado de trabajo. No obstante la ampliación de la matrícula educativa femenina y su ritmo de crecimiento, los destinos educativos de hombres y mujeres no se igualan.
Las políticas públicas frente a la diversidad socioespacial y simbólica
Authors: Guillén Lúgigo Manuela
Published: August 2021

El presente trabajo tiene el propósito de reflexionar sobre la diversidad y heterogeneidad simbólica de los contextos de segregación urbana, a los cuales están dirigidos gran parte de los programas de combate a la pobreza. En particular nos interesa reflexionar en torno a algunas de las implicaciones prácticas y simbólicas de dicha diversidad, encontradas en dos barrios de la periferia de Hermosillo. Dichos barrios constituyeron el escenario de una investigación realizada con el propósito de identificar las representaciones sociales que se construyen en escenarios de segregación urbana.
Procesos de exclusión e inclusión social. Indicadores, Conceptos, Contextos y Significados
Authors: Martínez Rascón Cristina
Published: August 2021

La edición de un texto de colegas cercanos siempre es motivo de alegría y celebración…esa emoción también me la produjo el saber de la existencia de un nuevo título que como socióloga y profesora de cursos de metodología incorporaré de inmediato en mis programas. ¿Porqué lo digo con ese convencimiento? Pues tan simple como que trata una discusión impecablemente sociológica y actual con el superávit de enfatizar los hilos finos de los resultados de las investigaciones presentadas, esto es, explicitando los aspectos metodológicos de los procesos estudiados. Si bien es cierto que la noción de exclusión social surgió y se popularizó en los años setenta y ochenta en Francia para referirse a los sectores desfavorecidos y afectados por los nuevos problemas sociales que las viejas políticas del estado del bienestar no dieron respuesta, y que ahora exigían reinsertarse mediante programas específicos, su difusión se acrecentó en Europa, Estado Unidos y Latinoamérica por el fenómeno compartido de la pobreza y el insuficiente desarrollo local.

Published: August 2021

The study aimed at investigating the role of women’s organizations in the management and reduction of drought impact formally and informally in Kajiado County, Kenya. The study, therefore, examined how women’s organizations create awareness in ownership rights to empower women and determined how gender policies by women’s organizations influence the empowerment of women. The study also examined how income generating activities by women’s organizations led to women's empowerment and the extent to which women’s organizations mobilize resources to empower women. The systems theory of organizations was used to understand the dynamics of women group organizations. A total of 20 women group organizations were included in the study, accounting for 500 members. Questionnaires were used for data collection and the data was analysed through quantitative means. Most women’s organizations creating awareness in ownership rights to empower women do not own assets of their own and believe that the land they live in belongs to their husbands and that they are in control over it. Most of the organizations generate income for women through activities such as the sale of farm produce, cash from labour activities and cash from their husbands. Based on the findings, the study recommended that leaders should establish women’s councils to participate in leadership matters to empower them and be part of agenda formulation and decision making
University Education and Values Re-Orientation for Socio-Economic Development in Nigeria
Authors: Ofor-Douglas Stella
Published: August 2021

This paper seeks to expound on the role of university education in promoting value orientation for socio-economic development in Nigeria. A quick examination of the terms of university education, value re-orientation and socio-economic development will be made in order to link how they lead to each other. With a comprehensive literature review, these terms will be viewed side by side with the opinions of various scholars to offer expert opinions on their background. University education is far more than just giving theoretical skills to students that will only be applied to their jobs in the future. Rather, the university environment can be used as a reservoir of value systems that can be passed to students so they can have improved mindsets and lifestyles that work beyond a job. The objectives of this paper are to create an understanding of the ways that are possible to achieve national socio-economic development through the university system which should make a change in its previous methods by now emphasising the necessity of value re-orientation to impact the lives of students. Through this expected impact, youths will improve mentally, emotionally and build an industrious work ethic for more than just study-related matters. They will be able to contribute immensely to changes in the nation and step by step, the country can experience a turnaround in its socio-economic development. The importance of this effort will be highlighted and issues that hinder the discovery of this paper’s goal will be deduced and allotted appropriate solutions applicable in real-life situations. Suitable suggestions will be made to give a reader practical knowledge on how to sustain the solutions provided in this paper
