1. Bibliometric analysis of global sickle cell disease research from 1997 to 2017
Abstract Introduction Sickle cell disease is an autosomal recessive genetic disease caused by a single point mutation in the β-globin chain of the hemoglobin. It has been recognized by the World Health Organization as a public health priority since 2006. Methods The Scopus database was used in this study with the search descriptors: “sickle cell” and

2. Estimation and Mapping of the Received Power Level of Digital Signals TV Using Spatial Interpolation Methods
Abstract The signal digitization process of the open television system is still in progress, therefore, the study of the digital signal propagation has great importance so that broadcasters can develop and improve the transmission service. The field measurement of digital signal parameters is one of the most reliable means to analyze the signal propagation i

3. Estimating leaf area of basil cultivars through linear dimensions of leaves
ABSTRACT Ocimum basilicum L. (basil) is an annual herb belonging to the Lamiaceae family that has economic importance for many regions around the world. Thus, ecophysiological studies are needed to assess this species growth and dispersal. This work aimed to obtain equations from regression models that meaningfully estimate the leaf area of basil cultivars u

4. Cardiovascular Risk Factors, Functionality, and Quality of Life in Climacteric Women
Abstract Background: Cardiovascular disease (CVD) comprises a group of cardiac and circulatory diseases. Despite the high incidence in males, women after menopause have an exponential increase in the risk of CVD. Objective: To identify the leading risk factors for CVD and describe quality of life and functionality in women hospitalized for cardiac causes d

5. Non-Ionizing Radiation Analysis in Close Proximity to Antenna Tower: A Case Study in Northeast Brazil
Abstract While the amount of telecommunications services grows rapidly in the whole world, humans get potentially more exposed to Non-Ionizing Radiation (NIR) from a number of different sources. Measurements of NIR levels are relevant in order to compare the results with national and international standards, aiming at the preservation of human health. Thus,

6. Teleconsultation and Teletreatment Protocol to Diagnose and Manage Patients with Benign Paroxysmal Positional Vertigo (BPPV) during the COVID-19 Pandemic
Abstract Introduction Telehealth consists in the application of technology to provide remote health service. This resource is considered safe and effective and has attracted an exponential interest in the context of the COVID pandemic. Expanded to dizzy patients, it would be able to provide diagnosis and treatment, minimizing the risk of disease transmissio

7. Exponential stabilty for a Timoshenko system with nonlocal delay
RESUMO O objetivo deste artigo é estudar o sistema de Timoshenko com uma condição de retardo de tempo não local. A boa colocação é provada através do teorema de Hille- Yosida. Explorando as propriedades dissipativas do operador linear associado ao modelo totalmente amortecido, obtemos a estabilidade exponencial usando o Teorema de Gearhart- Huang-Pr�

8. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

11. Comparative study of inclusion removal from liquid steel in the RH and argon purging processes
Abstract In order to improve steel quality, it is necessary to increase the cleanliness of the liquid steel; that is, to reduce the number and size of the inclusions in the liquid steel, as well as to control their chemical composition. For this purpose, processes (with different operating costs) are used, such as the bubbling of inert gas in the steel ladle

12. ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES
ABSTRACT Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for this purpose. Thus, this study aimed to evaluate, using exponential and polynomial regression mo
