1. Camisinha feminina é segura?
Sim. Além da prevenção da gravidez indesejada, o preservativo feminino, se uso perfeito, apresenta eficácia de 95% e de 79% com uso típico. A eficácia contraceptiva do preservativo feminino é provavelmente semelhante à do preservativo masculino.
Extrapolações de resultados sobre a eficácia contraceptiva sugerem que o preservativo feminino

2. New Use of an Absorbable Adhesion Barrier (INTERCEED) for Temporary Diverting Ileostomy in Minimally Invasive Rectal Surgery
ABSTRACT Objectives Sometimes, severe adhesion occurs between the rectus abdominis muscle and the ileal intestinal limbs after temporary diverting ileostomy. This can make ileostomy reversal difficult. The aim of the present study is to assess whether absorbable adhesion barrier made of oxidized regenerated cellulose (INTERCEED) could contribute to improved

3. Analysis of dielectric and electrical transport properties of NdFeAsO ceramic
Abstract The iron-based ceramic NdFeAsO was synthesized by the solid-state reaction method. The tetragonal crystal structure was confirmed at room temperature through the X-ray diffraction technique. The dielectric characteristics i.e. dielectric constant (εr) and loss tangent (tanδ) of the sample were studied at a wide range of temperature and frequencies

4. Evaluation of the Current in the Cell Membrane for Numerical Simulations of Electroporation
Abstract This study presents a rigorous numerical analysis of the current in the cell membrane, subjected to a uniform electric field, and its impact in the pore formation. The numerical model considers a single cell composed of uniform membrane and cytoplasm, in a suspension medium. The current in the cell membrane is calculated using two different approach

5. A Physical Study to Explain Response Differences between the BID and FID Detectors for PAHs and Pesticides
The dielectric barrier discharge ionization detector (BID) is one of the most modern detectors commercially available for gas chromatography (GC). Its technology based on the sample ionization through the energy released from the helium plasma generation process gives it the ability to act as a universal detector and a greater response to various types of co

8. Barriers to physical activity among adults in primary healthcare units in the National Health System: a cross-sectional study in Brazil
ABSTRACT BACKGROUND: Many factors may negatively impact physical activity (PA), but studies lack evidence of individual predictors of perceived barriers to PA among adults in primary healthcare units. OBJECTIVE: To analyze associations between sociodemographic characteristics, health conditions, leisure-time physical activity (LTPA), PA counseling and perc

9. Heterogeneous Fenton-like catalytic degradation of phenazine dye over CeO2 (CP-2) nanoscale powder
Abstract A heterogeneous Fenton-like process was explored for oxidation of phenazine dye using ceria polishing material (CP-2). XRD, SEM, FTIR, UV-vis DRS, and pHPZC techniques were applied to characterize the catalyst features. The performance of the heterogeneous Fenton-like process was investigated under various parameters (reaction time, pH, H2O2 concent

10. High-barrier and antibacterial films based on PET/SiOx for food packaging applications
Abstract High-barrier and antibacterial materials have potential applications in the field of preservative packaging for fresh meat products. In this paper, UV irradiation and silane coupling agent (KH550) were used to modify the surface of SiOx coating on polyester (PET)/SiOx film to prepare the PET/SiOx/chitosan and PET/SiOx/chitosan-nano-ZnO composite fil

11. Barrier for Particle Dispersion Control During Mastoidectomy
Abstract Introduction The China Health Authority alerted the World Health Organization (WHO) of several cases of pneumonia, and the WHO has declared the novel coronavirus (COVID-19) a global pandemic. Mastoidectomy is a high-risk aerosol generating procedure with the potential to expose the surgeon to infectious particles. Objective Aim to develop a low-co

12. 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
