2. Hypotension and Bradycardia Produced by Transthoracic Application of Low-Intensity Ultrasound Therapy in Hearts of Healthy Rats - A Preclinical Study
Abstract Objective: To investigate the cardiovascular effects produced by transthoracic application of low-intensity pulsed ultrasound therapy (LIPUST). Methods: Three-month-old male Wistar rats (± 300 g, N=16) were randomly allocated in two groups, namely SHAM (control group, faked procedures) and UST (animals treated with LIPUST). These animals, under a

3. Aníbal Quijano em seu labirinto: metamorfoses teóricas e utopias políticas
Resumo O objetivo deste artigo é discutir alguns desdobramentos presentes na trajetória intelectual e política de Aníbal Quijano (1930-2018). Procura-se reconstruir especialmente o contexto de “crise dos paradigmas” das ciências sociais e de declínio da esquerda marxista, que se manifestaram de modo acentuado na década de 1980, examinando como o s

6. THE EFFECT OF BCAA ON ISOMETRIC FORCE FOLLOWING ENDURANCE EXERCISE IN A HOT ENVIRONMENT
RESUMO Introdução: A fadiga decorrente de um exercício de endurance ocorre devido a alterações tanto periféricas quanto centrais e pode influenciar no desempenho subsequente durante um teste de força. Sabe-se que o aumento da concentração de serotonina é um dos fatores centrais associados à fadiga induzida pelo exercício de endurance, principalm

9. Technical efficiency analysis of marine shrimp farming (Litopenaeus vannamei) in biofloc and conventional systems: A case study in northeastern Brazil
Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Lit

10. Fundamental Consideration for Electrochemical Engineering of Supercapattery
Supercapattery is the generic name for various electrochemical energy storage (EES) devices combining the merits of battery (high energy density) and supercapacitor (high power density and long cycling life). In this article, the principle and applications of EES devices are selectively reviewed as the background for supercapattery development. The focus is

12. Films Deposited from Reactive Sputtering of Aluminum Acetylacetonate Under Low Energy Ion Bombardment
Films were deposited from aluminum acetylacetonate (Al(acac)3) using a methodology involving reactive sputtering and low energy ion bombardment. The plasma was generated by the application of radiofrequency power to the powder containing electrode and simultaneously, negative pulses were supplied to the electrode where the substrates were attached. It was in
