1. Radially Periodic Metasurface Lenses for Magnetic Field Collimation in Resonant Wireless Power Transfer Applications
Abstract In this paper, a new procedure and topology of magnetic metasurface lens are proposed for improving the performance of Resonant Wireless Power Transfer systems. Firstly, three subwave-length unit cells are optimized in order to get negative magnetic permeability in the same frequency, each one with a different refractive index, and they are experime

2. DRYING CHARACTERISTICS AND QUALITY ANALYSIS OF HOT AIR-ASSISTED RADIO FREQUENCY AND HOT-AIR DRYING OF JUJUBE ( Zizyphus jujube Miller cv. Jinsixiaozao )
ABSTRACT Radio frequency (RF) drying is a rapid dehydration technique that reduces water activity and extends the shelf life of agricultural products. In this study, the drying characteristics of jujube during HARF and hot air (HA) were investigated, and quality analyses, such as color, vitamin C (VC) and total flavonoid content (TFC), of jujube were perform

3. Encapsulation technique efficiency in high zinc chloride concentration clayey soil with traditional agents
RESUMO Ainda que a técnica de encapsulamento seja usada na remediação ambiental há mais de três décadas, existem poucos estudos que avaliam sua eficácia para altas concentrações de contaminantes. Assim, este trabalho tem como objetivo avaliar a eficiência da técnica de encapsulamento de solo argiloso contaminado com 5 e 10% de cloreto de zinco, ut

4. Optimizing the recovery of peripheral blood mononuclear cells trapped in leukoreduction filters - A comparison study
Abstract Introduction The isolation of captured peripheral blood mononuclear cells (PBMNCs) from leukoreduction filters (LRFs) can be of great importance in terms of bringing the lost cells back into use. Objective The aim of this study was to evaluate various methods based on their potential to recover the peripheral blood cells from LRFs with a focus on

5. Lipoprotein apheresis efficacy and challenges: single center experience
Abstract Introduction Lipoprotein apheresis (LA) is an extracorporeal therapy which removes apolipoprotein B-containing particles from the circulation. We evaluated techniques and efficiency of lipoprotein apheresis procedures applied to patients with familial and non-familial hypercholesterolemia (FH) at our center. Methods We retrospectively evaluated 25

6. IRRIGATION WATER MANAGEMENT TECHNIQUES FOR LOWLAND FURROW-IRRIGATED SOYBEAN IN SOUTHERN BRAZIL
ABSTRACT Different water management strategies should be investigated to ensure adequate water supply to furrow-irrigated soybean plants in lowlands. This study examined the performance and efficiency of furrow irrigation techniques and related them to the soybean yield potential in lowland fields of Southern Brazil in the 2017/18 growing season. An experime

8. A Green Procedure Using Disposable Pipette Extraction to Determine Polycyclic Aromatic Sulfur Heterocycles in Water Samples and Solid Petrochemical Residues
A simple and efficient method using reduced amounts of solvents for the determination of polycyclic aromatic sulfur heterocycles (PASHs) in aqueous matrices from a lagoon and leachate solid waste from a petrochemical industry is proposed. The target analytes were previously concentrated using the disposable pipette extraction (DPX) technique applying gas chr

9. Abscesso retrofaríngeo complicado: uma causa atípica de mielopatia
In order to increase the specific surface area of Pt-Rh-Pd / Al2O3 automotive three-way catalyst and improve its low-temperature reduction performance, Ce, Zr, and La were added to the Pt-Rh-Pd / Al2O3 catalyst to prepare the fibrous Pt-Rh-Pd / CeO2-ZrO2-La2O3-Al2O3 catalyst via an electrospinning technique. The fibrous catalysts were characterized by XRD, F
