1. Validation of the Grace Risk Score to Predict In-Hospital and 6-Month Post-Discharge Mortality in Patients with Acute Coronary Syndrome
Abstract Background The wide range of clinical presentations of acute coronary syndrome (ACS) makes it indispensible to use tools for risk stratification and for appropriate risks management; thus, the use of prognosis scores is recommended in the immediat clinical decision-making. Objective To validate the Global Registry of Acute Coronary Events (GRACE

2. Polyacrylamides as co-depressant in hematite and quartz microflotation
Abstract In the present study, microflotation experiments were performed on pure minerals systems involving hematite and quartz in the presence of etherdiamine as collector. The influence of polyacrylamides as co-depressant was investigated in a blend with starch depressant. The results obtained demonstrated that all the polyacrylamides used were efficient i

4. Single-Layered Paper-Based Microfluidic Devices Made by Paint-Spraying Technique with Great Barrier Resistance for Colorimetric Assays
The single-layered paint-spraying paper based microfluidic devices (sp-μPADs) have been for the first time integrated with the colorimetric assay. The polymethyl methacrylate (PMMA) board was applied as the mask instead of the iron mask, reducing the power requirement of the cutting machine. The paint was sprayed into the paper, which blocked the pores of t

5. Optimization of hot-air drying conditions on functional properties of flour from dried South African sweet potato cultivars (Impilo and Bophelo) using the response surface methodology
Abstract The response surface method (RSM) has an important application in formulation of new products. This study determined the effect of electric hot-air drying on the functional properties of flour made from orange-fleshed sweet potato (OFSP). Flour from the cultivars Bophelo (B) and Impilo (IM) were treated with 13 temperature-time combinations designed

6. Prognosis of Heart Failure with Preserved Ejection Fraction in Primary Care by the H2FPEF Score
Abstract Background: Primary care physicians have difficulty dealing with patients who have HF with preserved LVEF(HFpEF). The prognosis of HFpEF is poor, and difficult to predict on primary care. Objective: The aim of the study is to apply the H2FPEF score to primary care patients and verify its power to assess the risk of death or hospitalization due to

7. High Efficiency Continuous Inverse Class-F Power Amplifier with Modified Current Waveform
Abstract Continuous inverse class-F (CICF) is a recent mode of harmonically-tuned RF power amplifiers used to extend the operating bandwidth of the conventional narrowband class-F−1 power amplifier by producing variable set of drain current waveforms and load admittances that give the same operating efficiency. In this work, a new approach of analysis is d

8. Properties of wheat and rice breads added with chia (Salvia hispanica L.) protein hydrolyzate
Abstract Bioactive, technological and sensory properties of wheat and rice breads added of chia (Salvia hispânica L.) protein hydrolyzate were evaluated. The hydrolyzate was added to breads at concentrations of 1, 3 and 5 mg of hydrolyzate/g of flour. The specific volume, total score, bread crumb firmness, color, sensory analysis and antioxidant activity of

9. NANO-ENCAPSULATION OF Lippia origanoides KUNTH. ESSENTIAL OIL BY CHITOSAN-CAFFEIC ACID NANOGEL
In this study, a nanogel was developed from a natural polymer, chitosan, to be used in the Lippia origanoides essential oil encapsulation. The encapsulation process was used in order to improve the functional capacity of this essential oil as an antioxidant. To obtain the nanogel, the chitosan was modified with caffeic acid using EDC coupling agent. The obta

10. PHYSICAL ACTIVITY AND PHYSICAL FITNESS AMONG FILIPINO UNIVERSITY STUDENTS
ABSTRACT The purpose of this study is to examine the physical activity and physical fitness of university students. Four hundred seventy-four apparently healthy university students (167 males; 307 females) answered a physical activity questionnaire and underwent anthropometric and physical fitness assessments. Results indicated that male university students
