Authors: Zeshan Furkh , Ahmad Adnan , Abdel-Aty Abdel-Haleem , Algarni Fahad , Mahmoud Emad E. , Ahmad Ashfaq
Published: October 2020

Distributed systems provide smart functionality to everyday objects with the help of wireless sensors using the internet. Since the last decade, the industry is struggling to develop efficient and intelligent protocols to integrate a huge number of smart objects in distributed computing environments. However, the main challenge for smart and distributed system designers lies in the integration of a large number of heterogeneous components for faster, cheaper, and more efficient functionalities. To deal with this issue, practitioners are using edge computing along with server and desktop technology for the development of smart applications by using Service-Oriented Architecture (SOA) where every smart object offers its functionality as a service, enabling other objects to interact with them dynamically. In order to make such a system, researchers have considered context-awareness and Quality of Service (QoS) attributes of device services. However, context modeling is a complicated task since it could include everything around the applications. Moreover, it is also important to consider non-functional interactions that may have an impact on the behavior of the complete system. In this regard, various research dimensions are explored. However, rich context-aware modeling, QoS, user priorities, grouping, and value type direction along with uncertainty are not considered properly while modeling of incomplete or partial domain knowledge during ontology engineering, resulting in low accuracy of results. In this paper, we present a semantic and logic-based formal framework (hybrid) to find the best service among many candidate services by considering the limitations of existing frameworks. Experimental results of the proposed framework show the improvement of the discovered results.

Authors: Jin Jie , Chung Youngbeen , Park Junhong
Published: October 2020

(1) Background: This study is aimed at the development of a precise and inexpensive device for flow information measurement for external flow. This novel flowmeter uses an LSTM (long short-term memory) neural network algorithm to analyze the vibration responses of the gauge plate. (2) Methods: A signal processing method using an LSTM neural network is proposed for the development of mass flow rate estimation by sensing the vibration responses of a gauge plate. An FFT (fast Fourier transform) and an STFT (short-time Fourier transform) were used to analyze the vibration characteristics of the gauge plate depending on the mass flow rate. For precise measurements, the vibration level and roughness were computed and used as input features. The actual mass flow rate measured by using a weight transducer was employed as the output features for the LSTM prediction model. (3) Results: The estimated flow rate matched the actual measured mass flow rate very closely. The deviations in measurements for the total mass flow were less than 6%. (4) Conclusions: The estimation of the mass flow rate for external flow through the proposed flowmeter by use of vibration responses analyzed by the LSTM neural network was proposed and verified.

Published: October 2020

With the development of Internet of Things (IoT) applications, applying the potential and benefits of IoT technology in the health and environment services is increasing to improve the service quality using sensors and devices. This paper aims to apply GIS-based optimization algorithms for optimizing IoT-based network deployment through the use of wireless sensor networks (WSNs) and smart connected sensors for environmental and health applications. First, the WSN deployment research studies in health and environment applications are reviewed including fire monitoring, precise agriculture, telemonitoring, smart home, and hospital. Second, the WSN deployment process is modeled to optimize two conflict objectives, coverage and lifetime, by applying Minimum Spanning Tree (MST) routing protocol with minimum total network lengths. Third, the performance of the Bees Algorithm (BA) and Particle Swarm Optimization (PSO) algorithms are compared for the evaluation of GIS-based WSN deployment in health and environment applications. The algorithms were compared using convergence rate, constancy repeatability, and modeling complexity criteria. The results showed that the PSO algorithm converged to higher values of objective functions gradually while BA found better fitness values and was faster in the first iterations. The levels of stability and repeatability were high with 0.0150 of standard deviation for PSO and 0.0375 for BA. The PSO also had lower complexity than BA. Therefore, the PSO algorithm obtained better performance for IoT-based sensor network deployment.

Published: October 2020

The prevalence of obesity is increasing worldwide and is commonly associated with comorbidities. The use of several drugs is often necessary, which leads to Potential Drug Interactions (PDI) that may increase the morbidity and mortality. This study aimed to analyze the prevalence of drug interaction and its association with socio-demographics, health status, and drug use in severely obese individuals. Baseline data from a randomized clinical trial registered at Clinicaltrial.gov (NCT02463435) were used. A total of 150 individuals aged 18–65 years with a body mass index of 35 kg/m2 were included. The outcome variable was the presence of PDI, and the explanatory variables were divided into the following four levels: socio-demographic, lifestyle, health, and medication use. The prevalence of PDI was 50% (n = 75) (95% CI 41–58). The variables associated with drug–drug interactions in the multiple analyses were arterial hypertension (PR 1.83, 95%, CI 1.10–3.04), polypharmacy (PR 3.12, 95%, CI 2.17–4.50), and diabetes mellitus (PR 0.60, 95%, CI 0.45–0.81). The risk factors for the occurrence of drug interaction were the presence of diabetes mellitus, hypertension, and polypharmacy.

Published: October 2020

In urban contexts, the increasing density of electronic devices equipped with Global Navigation Satellite System (GNSS) receivers and complementary positioning technologies is attracting research and development efforts devoted to an improvement of the quality of life towards the smart city paradigm. Vehicular and pedestrian positioning and navigation capabilities are among the major drivers for innovation in this process. Ultra-low-cost electronics such as smartphones and Internet of Things (IoT) sensors aim at providing accurate and reliable positioning solutions through a set of promising solutions. Among these, snapshot positioning allows to remotely perform the post-processing of GNSS signals in IoT sensor networks while Wi-Fi™ ranging and cooperative positioning provide auxiliary anchors of opportunity to enhance indoor/outdoor positioning capabilities. This paper presents an innovative platform to perform a centralised testing and assessment of such positioning and navigation technologies along with a set of results obtained in the context of the European project HANSEL, by relying on current network technologies and infrastructures (i.e., Wi-Fi™ and cellular connectivity).
Lessons in Rural Persuasion: Village Infill Development in Bavaria, Germany
Authors: Gerend Jennifer
Published: October 2020

Sustainable rural development in Germany was examined by linking conceptual and applied aspects of the land and housing question, broadly considering the ownership, use, and regulation of land. In the state of Bavaria, a new interagency initiative aims to curb land consumption by persuading villagers to embrace rural infill development. The study explored the background debate leading up to the Space-saving Offensive (Flächensparoffensive), the resource providers involved, and the options for funding actual rural infill building and renovation projects. Here, space-saving managers and other resource providers actively promote the positive societal meaning of central infill sites in contrast to unsustainable land consumption. In addition to the communications campaign, planning, regulatory, and funding interventions round out the multi-level initiative, as described in this study. A modern barn reuse exemplifies the Bavarian bundle of resources, while demonstrating how modern village infill redevelopment also contests oversimplified notions of stagnant rural peripheries. The initiative’s focus on linking key resources and bolstering communications can be read as validation for a more social perspective on land consumption and village infill development.
Significant Labels in Sentiment Analysis of Online Customer Reviews of Airlines
Authors: Zaki Ahmed Ayat , Rodríguez-Díaz Manuel
Published: October 2020

Sentiment analysis is becoming an essential tool for analyzing the contents of online customer reviews. This analysis involves identifying the necessary labels to determine whether a comment is positive, negative, or neutral, and the intensity with which the customer’s sentiment is expressed. Based on this information, service companies such as airlines can design and implement a communication strategy to improve their customers’ image of the company and the service received. This study proposes a methodology to identify the significant labels that represent the customers’ sentiments, based on a quantitative variable, that is, the overall rating. The key labels were identified in the comments’ titles, which usually include the words that best define the customer experience. This database was applied to more extensive online customer reviews in order to validate that the identified tags are meaningful for assessing the sentiments expressed in them. The results show that the labels elaborated from the titles are valid for analyzing the feelings in the comments, thus, simplifying the labels to be taken into account when carrying out a sentiment analysis of customers’ online comments.
Study on Passive Ventilation and Cooling Strategies for Cold Lanes and Courtyard Houses—A Case Study of Rural Traditional Village in Shaanxi, China
Authors: Yao Xingbo , Dewancker Bart J. , Guo Yuang , Han Shuo , Xu Juan
Published: October 2020

China’s research on and specific implementation of energy saving for buildings are mainly concentrated in urban areas, but according to 2016 statistics, the rural population accounts for 42.65% of the total population, so rural housing has considerable energy-saving potential. However, the degree of attention to the energy consumption of rural houses needs to be improved. Regarding the research on and implementation of passive energy-saving strategies for residences, compared with centralized urban high-rise residences, rural residences mainly have independent courtyards, with a flexible layout and easier transformation. In this study, a system that uses the common cold lanes in traditional villages and buildings’ exterior walls was constructed, and the indoor spaces of courtyard buildings in southern Shaanxi were completely passively cooled in summer. This system can be completely separated from the supply of artificial energy by relying on the accumulation and buoyancy effects of air in patios and cold lanes and the hot-pressure ventilation in buildings to cool the buildings and greatly improve indoor ventilation efficiency. As the building is ventilated and cooled, the air wall formed in the system can effectively prevent direct contact between the outdoor and indoor temperatures and reduce the impact of thermal wall radiation on the interior. In previous studies on the passive design of courtyard houses, scholars considered the effect of thermal wall radiation on indoor temperature in simulations. Therefore, in this study, we also separately calculated whether to consider the difference between the situation with and without wall heat radiation (WHR) when simulating thermal conversion. The final results show that when the cooling system was adopted, the annual cooling load of the whole building was 4786.494 kW·h without WHR. However, with WHR, the cooling load reduction was 2989.128 kW·h, a difference of 1797.336 kW·h.
A 4+1 Formalism for the Evolving Stueckelberg-Horwitz-Piron Metric
Authors: Land Martin
Published: October 2020

We propose a field theory for the local metric in Stueckelberg–Horwitz–Piron (SHP) general relativity, a framework in which the evolution of classical four-dimensional (4D) worldlines xμτ (μ=0,1,2,3) is parameterized by an external time τ. Combining insights from SHP electrodynamics and the ADM formalism in general relativity, we generalize the notion of a 4D spacetime M to a formal manifold M5=M×R, representing an admixture of geometry (the diffeomorphism invariance of M) and dynamics (the system evolution of Mτ with the monotonic advance of τ∈R). Strategically breaking the formal 5D symmetry of a metric gαβ(x,τ) (α,β=0,1,2,3,5) posed on M5, we obtain ten unconstrained Einstein equations for the τ-evolution of the 4D metric γμν(x,τ) and five constraints that are to be satisfied by the initial conditions. The resulting theory differs from five-dimensional (5D) gravitation, much as SHP U(1) gauge theory differs from 5D electrodynamics.

Published: October 2020

Background: RT-PCR on nasopharyngeal (NPS)/oropharyngeal swabs is the gold standard for diagnosis of SARS-CoV-2 infection and viral load monitoring. Oral fluid (OF) is an alternate clinical sample, easy and safer to collect and could be useful for COVID-19 diagnosis, monitoring viral load and shedding. Methods: Optimal assay conditions and analytical sensitivity were established for the commercial Simplexa™ COVID-19 Direct assay adapted to OF matrix. The assay was used to test 337 OF and NPS specimens collected in parallel from 164 hospitalized patients; 50 bronchoalveolar lavage (BAL) specimens from a subgroup of severe COVID-19 cases were also analysed. Results: Using Simplexa™ COVID-19 Direct on OF matrix, 100% analytical detection down to 1 TCID50/mL (corresponding to 4 × 103 copies (cp)/mL) was observed. No crossreaction with other viruses transmitted through the respiratory toute was observed. Parallel testing of 337 OF and NPS samples showed highly concordant results (κ = 0.831; 95 % CI = 0.771–0.891), and high correlation of Ct values (r = 0.921; p < 0.0001). High concordance and elevated correlation was observed also between OF and BAL. Prolonged viral RNA shedding was observed up to 100 days from symptoms onset (DSO), with 32% and 29% positivity observed in OF and NPS samples, respectively, collected between 60 and 100 DSO. Conclusions: Simplexa™ COVID-19 Direct assays on OF have high sensitivity and specificity to detect SARS-CoV-2 RNA and provide an alternative to NPS for diagnosis and monitoring SARS-CoV-2 shedding.
Budding of a Retrovirus: Some Assemblies Required
Authors: Rose Kevin M. , Hirsch Vanessa M. , Bouamr Fadila
Published: October 2020

One of the most important steps in any viral lifecycle is the production of progeny virions. For retroviruses as well as other viruses, this step is a highly organized process that occurs with exquisite spatial and temporal specificity on the cellular plasma membrane. To facilitate this process, retroviruses encode short peptide motifs, or L domains, that hijack host factors to ensure completion of this critical step. One such cellular machinery targeted by viruses is known as the Endosomal Sorting Complex Required for Transport (ESCRTs). Typically responsible for vesicular trafficking within the cell, ESCRTs are co-opted by the retroviral Gag polyprotein to assist in viral particle assembly and release of infectious virions. This review in the Viruses Special Issue “The 11th International Retroviral Nucleocapsid and Assembly Symposium”, details recent findings that shed light on the molecular details of how ESCRTs and the ESCRT adaptor protein ALIX, facilitate retroviral dissemination at sites of viral assembly.
A Comprehensive Proteomics Analysis of the JC Virus (JCV) Large and Small Tumor Antigen Interacting Proteins: Large T Primarily Targets the Host Protein Complexes with V-ATPase and Ubiquitin Ligase Activities While Small t Mostly Associates with Those Having Phosphatase and Chromatin-Remodeling Functions
Authors: Saribas Sami , Safak Mahmut
Published: October 2020

The oncogenic potential of both the polyomavirus large (LT-Ag) and small (Sm t-Ag) tumor antigens has been previously demonstrated in both tissue culture and animal models. Even the contribution of the MCPyV tumor antigens to the development of an aggressive human skin cancer, Merkel cell carcinoma, has been recently established. To date, the known primary targets of these tumor antigens include several tumor suppressors such as pRb, p53, and PP2A. However, a comprehensive list of the host proteins targeted by these proteins remains largely unknown. Here, we report the first interactome of JCV LT-Ag and Sm t-Ag by employing two independent “affinity purification/mass spectroscopy” (AP/MS) assays. The proteomics data identified novel targets for both tumor antigens while confirming some of the previously reported interactions. LT-Ag was found to primarily target the protein complexes with ATPase (v-ATPase and Smc5/6 complex), phosphatase (PP4 and PP1), and ligase (E3-ubiquitin) activities. In contrast, the major targets of Sm t-Ag were identified as Smarca1/6, AIFM1, SdhA/B, PP2A, and p53. The interactions between “LT-Ag and SdhB”, “Sm t-Ag and Smarca5”, and “Sm t-Ag and SDH” were further validated by biochemical assays. Interestingly, perturbations in some of the LT-Ag and Sm t-Ag targets identified in this study were previously shown to be associated with oncogenesis, suggesting new roles for both tumor antigens in novel oncogenic pathways. This comprehensive data establishes new foundations to further unravel the new roles for JCV tumor antigens in oncogenesis and the viral life cycle.

Modelling of the Complex Groundwater Level Dynamics during Episodic Rainfall Events of a Surficial Aquifer in Southern Italy
Authors: Pastore Nicola , Cherubini Claudia , Doglioni Angelo , Giasi Concetta Immacolata , Simeone Vincenzo
Published: October 2020

We analyzed the complex dynamics that are involved the groundwater level variations due to the episodic rainfall supply in the Ionian coastal plain surficial aquifer located in Southern Italy. In this aquifer, as a consequence of the particular hydrogeological framework, both direct and lateral recharge mechanisms coexist. Hence, the dynamics of groundwater level variations are quite complex and strongly non-linear. Our focus was essentially on the short-term behavior of groundwater levels, with a specific analysis on episodic rainfall events. To model these dynamics, due to the presence of the preferential pathways in the infiltration processes, a kinematic dispersion wave model was used. Specifically, a one-dimensional and non-linear particle-based numerical model was developed. It uses ideal particles with constant water volume travel, according to celerity and hydraulic dispersion, to simulate the infiltration rate wave through the vadose zone. The infiltration rate that reaches the water table represents the input function to evaluate the aquifer groundwater level fluctuations. As a consequence of the special lithological and storage capacity characteristics of the surficial layers, groundwater flow conditions change from unconfined to confined. The developed model analyzes the direct groundwater supply under natural conditions, including episodic rainfall, and it has been validated using a high-resolution time series of rainfall data and groundwater level obtained from the monitoring station Terra Montonata.

Published: October 2020

The paper is focused on the evaluation of long-term changes in the chemical composition of precipitation in the mountain forests of Slovakia. Two stations with long-term measurements of precipitation quality were selected, namely the station of the EMEP (European Monitoring and Evaluation Programme) network Chopok (2008 m a.s.l.) and the station of the ICP Forests (International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests) network Poľana-Hukavský grúň (850 m a.s.l.). All basic chemical components were analyzed, namely sulfur (S-SO4), nitrogen (N-NH4, N-NO3), and base cations (Ca, Mg, and K) contained in precipitation. The time changes of the individual components were statistically evaluated by the Mann–Kendall test and Kruskal–Wallis test. The results showed significant declining trends for almost all components, which can significantly affect element cycles in mountain forest ecosystems. The evaluated forty one-year period (1987 to 2018) is characterized by significant changes in the precipitation regime in Slovakia and the obtained results indicate possible directions in which the quantity and quality of precipitation in the mountainous areas of Slovakia will develop with ongoing climate change.
Managing older people’s perceptions of alcohol-related risk: a qualitative exploration in Northern English primary care
Authors: Bareham Bethany Kate , Kaner Eileen , Hanratty Barbara
Published: October 2020

Background

Risk of harm from drinking increases with age as alcohol affects health conditions and medications that are common in later life. Different types of information and experiences affect older people’s perceptions of alcohol’s effects, which must be navigated when supporting healthier decisions on alcohol consumption.

Aim

To explore how older people understand the effects of alcohol on their health; and how these perspectives are navigated in supportive discussions in primary care to promote healthier alcohol use.

Design and setting

A qualitative study consisting of semi-structured interviews and focus groups with older, non-dependent drinkers and primary care practitioners in Northern England.

Method

A total of 24 older adults aged ≥65 years and 35 primary care practitioners participated in interviews and focus groups. Data were analysed thematically, applying principles of constant comparison.

Results

Older adults were motivated to make changes to their alcohol use when they experienced symptoms, and if they felt that limiting consumption would enable them to maintain their quality of life. The results of alcohol-related screening were useful in providing insights into potential effects for individuals. Primary care practitioners motivated older people to make healthier decisions by highlighting individual risks of drinking, and potential gains of limiting intake.

Conclusion

Later life is a time when older people may be open to making changes to their alcohol use, particularly when suggested by practitioners. Older people can struggle to recognise potential risks or perceive little gain in acting on perceived risks. Such perceptions may be challenging to navigate in supportive discussions.

E-government services or systems aim to improve the quality of services, enabling time and effort savings in government administration. The use of e-government services is not limited to the millennials, but also the people who were laymen of a system. Besides, millennials who sometimes still use information from parents or others who have used the previous system can use the information to miss the benefits of the system that has been done online so that the effort to use the system is low. This research is about online marriage registration services on the Simkah web application owned by the Ministry of Religion of the Republic of Indonesia because there are still many prospective brides or people who have not used the online service. The model used is to combine the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model and the modified IS DeLone and McLean (D&M) success model and consider moderating age, gender, and internet experience. In this study, it is necessary to know whether the constructor factors in the UTAUT2 model and the D&M model influence the intention to use online marriage registration services. The study was conducted in Sleman Regency. The construct finding that affects the intention to use online marriage registration services is hedonic motivation so the Ministry of Religion needs to increase hedonic motivation or mean it as an impulse in someone to use something.

Objective to study the adherence to the principles of rational nutrition by representatives of various professional groups living in the Russian Federation and the Republic of Tajikistan.
Material and methods.The study was conducted using a questionnaire-survey method among 543 mental workers of the Samara region and 158 students of the Avicenna Tajik State Medical University (Republic of Tajikistan), followed by statistical processing of the data.
Results.Violations of the principles of rational nutrition are commonin various professional groups of the working-age population, including among students of a medical university. According to anthropometric studies, 61% of the surveyed workers were overweight and obese; in the group of students this indicator was only 8%, 29% of students were underweight. Violations of nutrition regimen were found among 31.1% of employees and 38% of students. Factor analysis of the actual nutrition of workers revealed 5 types of nutrition models characterized by a stereotype of eating behavior due to the consumption of certain foods and beverage. The regression analysis confirmed the relationship between the risk of obesity and adherence to types 2, 4 and 5 of nutritional models; an individual's adherence to nutritional model type 3 reduced this risk. In the group of the surveyed, the deterioration of the diet quality was revealed due to the excessive consumption of high-calorie foods, "fast food", sweet carbonated drinks, as well as insufficient consumption of vegetables, fruits, fish. The correlation analysis established the relationship between the body mass index and complaints presented by the survey participants concerning the cardiovascular, digestive, endocrine and musculoskeletal systems. The study identified the most common alimentary-dependent pathologies among students such as gastritis, chronic pancreatitis, and chronic cholecystitis.
Conclusion.The revealed violations of the principles of rational nutrition, the nutritional status, form the risks of development of the gastrointestinal tract diseases, metabolic disorders and cardiovascular pathology. The results obtained indicate the need of preventive measures in relation to the adherence to the principles of rational nutrition, creating awareness in various professional groups of the population, including students of medical universities in different states.
La policía como actor político

Published: October 2020

La novela de George Orwell (2010, p. 5) “1984” describe una sociedad bajo el control del Estado que determina cómo pensar, vivir, educarse, y en sí, comportarse, para preservar la convivencia social. Este texto comporta un antecedente presente en la sociedad del siglo XXI, que cada vez es más vigilada, recreando un aspecto de la sociedad que se pretende abordar: las instituciones de control social, en específico la Policía, vista como un actor que juega un papel preponderante en las relaciones sociopolíticas. La policía se recoge en los términos de LeClere (1965, p 46) como unas entidades de diversas denominaciones: gendarmerías, milicias, cuerpos de seguridad y otras acepciones que han ejercido la función histórica del control en las civilizaciones primitivas, antiguas, modernas y contemporáneas.
Balance de los derechos de participación en Ecuador

Published: October 2020

El objetivo de la incorporación de los derechos de participación en la Constitución ecuatoriana del 2008 era la necesidad de establecer una mayor relación entre Estado y sociedad, es decir que el ciudadano sea parte en la toma de decisiones sobre los asuntos de interés público. Específicamente en ese sentido Boaventura de Sousa, plantea que la democracia participativa viene a ser complementaria de la representativa (Santos, 2004). Esto con la finalidad de intentar superar la crisis que sufría el modelo representativo liberal (Santos, 2004). Así, el constituyente ecuatoriano instituyo nuevos derechos, garantías e instituciones con ese propósito. No obstante, a nueve años de esa promesa constituyente, existen muchas críticas, y detractores de esta. En este trabajo, me propongo revisar algunas de estas objeciones, desde una perspectiva analítica y critica.

Normal fetal growth and development depends on adequate perfusion of the intervillous space through the maternal spiral arterioles. Reduced perfusion is associated with asymmetrical retardation of the fetal growth and fetal hypoxia that is the major cause of perinatal mortality.

Pregnancy induced hypertension (PIH) remains the major cause of maternal and perinatal morbidity and mortality. With the help of colour Doppler, the identification of vessels that are evaluated for Doppler study can become simple1. Hence role of Doppler examination has become indispensable in screening, diagnosis and management of PIH and IUGR cases2. With the aid of colour Doppler, IUGR can be diagnosed before it is clinically evident.
In the present study, we examined flow velocity waveforms in uteroplacental (uterine artery and umbilical artery) and fetoplacental (middle cerebral artery) circulations in both normal pregnancy3 and in situations of suspected placental insufficiently such as PIH and IUGR pregnancies4. Subsequently result in birth of growth retarded infant, to derive pathophysiological information about placental flow resistance and assess the diagnostic potential of this measurement.
PROPOSED ESTROGEN THERAPY FOR COVID 19 AND OTHER MICROBIAL INFECTIONS

The novel coronavirus or SARS CoV-2 infection or COVID 19, which originated in Wuhan, China is an infection with a new coronavirus. Since there was no previous human exposure to this virus, there was no herd immunity. Despite this universal absence of herd and adaptive immunity, there are considerable gender differences in mortality among men and women. In addition, mortality in children is considerably low as compared to adults (https://www.worldometers.info/coconavirus/Coronavirus-age-sex-demographics/ Coronavirus Age, Sex, Demographics (COVID 19) – Worldometer).
This implies stronger innate and adaptive immunity are at play in children and women as compared to that in adult men. Less severe affliction of women may be due to higher levels of estradiol in pre-menopausal women that in men. Estradiol has a favorable influence on innate and adaptive immunity (Carmen Giefing-Kröll et al. Aging Cell. 2015 Jun; 14(3): 309–321). Arsenicum Album 30, a homeopathic medicine, recommended by the Ministry of AYUSH, Government of India, (https://www.ayush.gov.in/docs/homeopathy-guidelines.pdf) has arsenic, which is a metalloestrogen (P D Darbre J Appl Toxicol. May-Jun 2006; 26(3):191-7); which appears to be the reason for its effectiveness in the treatment of COVID 19 or SARS Cov-2. Estradiol has thromboembolic effects when administered orally. However, transdermal estradiol is safer, without thromboembolic effects and is already in use in some countries (Archer DF et al. Climacteric. 2012 Jun;15(3):235-40.; Marianne Canonico et al Circulation. 2007;115:840–845).
Estrogen therapy is given in some forms of prostatic cancer in men. In view of these potential benefits of estrogen, estradiol transdermal therapy should be tried as a repurposed or investigational drug along with routine treatment of COVID 19 in men and post-menopausal women and in similar infections with new microbes in the absence of specific treatment.

Los odontólogos deben mantener un alto nivel de conciencia para ayudar a los pacientes, a minimizar el riesgo y prevenir la propagación viral, así comola incorporación de la teleodontología ayudará a reducir el número de consultas innecesarias.
REIMPLANTE INTENCIONAL: REPORTE DE CASO
Authors: Espinoza Miranda Ismael
Published: October 2020

El reimplante intencional está destinado a tratar dientes que no pueden ser tratados de forma predecible por otros medios o técnicas, teniendo siempre en consideración el deseo del paciente de mantener sus dientes naturales, así como sus expectativas. Consiste en extraer un diente y reinsertarlo en el alveólo después de la manipulación odontológica, obteniendo un relleno del conducto radicular/ ápice radicular o ambos. El reimplante intencional a menudo se considera un procedimiento de último recurso, probablemente debido a la gran variación en la tasa de éxito reportadas en la literatura y a la ausencia de un protocolo establecido. En este caso clínico se describe el protocolo del reimplante intencional utilizado en una mujer de 43 años de edad que fue remitida a la clínica del máster en Endodoncia de la Universidad Europea de Madrid con periodo de seguimiento de 1 año.

Upaya dalam pemenuhan kebutuhan pangan berupa beras dapat ditempuh melalui perluasan areal contohnya yaitu lahan salin maupun lahan tergenang. Lahan salin maupun lahan tergenang mempunyai faktor pembatas yang dapat menurunkan pertumbuhan tanaman padi. Tujuan penelitian yaitu: (1). Mengkaji respon ketahanan tanaman padi varietas IPB 4S terhadap cekaman salinitas dan cekaman genangan selama fase vegetatif awal; dan (2). Mengetahui interaksi pengaruh antara cekaman salinitas dan cekaman genangan terhadap pertumbuhan tanaman padi selama fase vegetatif awal. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor. Faktor pertama yaitu cekaman salinitas yang terdiri atas 3 level yaitu tanpa salinitas, NaCl 10%, dan NaCl 20%. Faktor kedua yaitu cekaman genangan yang terdiri atas 3 level yaitu tanpa genangan, digenangi 3 hari sekali, dan digenangi 6 hari sekali. Penelitian diulang sebanyak tiga kali. Pemberian cekaman salinitas dengan konsentrasi 10% dan 20% mampu menurunkan beberapa parameter tanaman padi seperti tinggi tanaman, bobot kering tajuk, biomassa tanaman, bagan warna daun, dan luas daun. Pemberian cekaman genangan selama 3 hari sekali dan 6 hari sekali tidak memberikan pengaruh terhadap pertumbuhan vegetatif awal tanaman padi varietas IPB 4S.

Published: October 2020

O objetivo do estudo foi comparar a avaliação de 46 pais e 82 professores de alunos do quinto ano do ensino fundamental de escolas municipais de Foz do Iguaçu – PR, quanto ao grau de importância, capacidade e conforto, atribuído a 23 temas em sexualidade, por meio de uma escala Likert de cinco pontos. Os pais relataram maior grau de importância, capacidade e conforto para discutir sobre temas da sexualidade com seus filhos do que os professores, e os temas relacionados ao ato sexual foram pontuados com menor grau por ambos. Os professores atribuíram muita capacidade apenas a tópicos relativos aos aspectos biológicos do corpo feminino e à gravidez. Este estudo reforça a necessidade da elaboração de programas de capacitação sobre sexualidade para professores e pais.
Percepções empreendedoras em tempos de crise: olhares dos discentes do curso subsequente em edificações - IFS campus Lagarto/SE
Authors: Siqueira Rosana Rocha , Costa Bruno dos Santos , Sacramento Tiffany Brunelly F.
Published: October 2020

O presente artigo tem como objetivo apresentar a autopercepção dos discentes do 4º período do curso de edificações, do IFS Campus Lagarto/SE, sobre características pessoais que possam fomentar atitudes empreendedoras, aproveitando conhecimento e práticas desenvolvidas no curso. A pesquisa surgiu da observação do quanto o “temor da crise” afeta a motivação dos discentes em relação às oportunidades para empreender. Trata-se de um estudo bibliográfico e de campo, do qual participaram turmas do 4º período do curso. Após a análise dos dados, percebeu-se que os discentes necessitam de maior fomento para desenvolver o hábito do planejamento em médio e longo prazos, que possibilite a autopercepção sobre oportunidades e desenvolvimento de carreiras, durante sua trajetória formativa - visando ao maior aproveitamento dos conteúdos -, e não apenas por ocasião do término do curso.
