1. Laryngopharyngeal Reflux: Symptoms, Signs, and Presence of Pepsin in Saliva - A Reliable Diagnostic Triad
Abstract Introduction Twenty-four-hour multichannel intraluminal impedance with double probe pH monitoring (MII-pH), though considered the most sensitive tool for the diagnosis of gastroesophageal reflux disease (GERD), is invasive, time consuming, not widely available, and unable to detect non-acid reflux. In contrast, the presence of pepsin in the saliva

2. Characterization of Sobradinho landslide in fluvial valley using MASW and ERT methods
Abstract Landslides can substantially impact the fluvial systems, which is why the continuous mapping of their extent, evolution and stability assessment is crucial. However, in such environments, material identification (e.g. colluvium) and subsurface characterization by the methods used for geologic mapping and geotechnical investigation is often a challen

3. Thermal Infrared Enthalpimetry in Paper Microzone Plates for Green and High Throughput Determination of Wine Acidities
The use of paper devices in chemical analysis has been increased due to their low cost, high surface area, portability, and biodegradability. A novel use of paper devices is proposed using thermal infrared enthalpimetry (TIE) for a rapid, green, and high throughput determination of wine acidities. The determination of total, fixed, and volatile acidities in

4. Adaptive Filtration of Parameters of the UAV Movement Based on the TDOA-Measurement Sensor Networks
ABSTRACT: In modern conditions unmanned aerial vehicles (UAVs) generate new classes of threats, including their use for terrorist purposes. A feature of modern UAVs is the ability to perform sudden maneuvers and to keep the same position in the point in space. For the description of the UAV movement with various types of maneuver it is used a rectangular coo

5. Size of samples and homogenizers during classification of damaged soybeans
RESUMO A determinação da qualidade de grãos envolve etapas importantes como a retirada da amostra representativa do lote, homogeneização e diluição. A inter-relação entre a amostragem, homogeneização e o tamanho da amostra de trabalho é fundamental para a fidedignidade da informação gerada. Assim, objetivou-se analisar o desempenho de homogenei

6. Robot-assisted single port radical nephrectomy and cholecystectomy: description and technical aspects
ABSTRACT Introduction Robot-Assisted Single Site Radical Nephrectomy (RASS-RN) has been reported by surgeons in Europe and United States (1–3). To our best knowledge this video presents the first RASS-RN with concomitant cholecystectomy performed in Latin America. Case A 66 year-old renal transplant male due to chronic renal failure presented with an inc

7. THEORETICAL RESEARCH ON THE MULTI-CHANNEL REACTION MECHANISM AND KINETICS OF HNCS WITH OH-
We presented a theoretical study on the detailed reaction mechanism and kinetics of the HNCS molecule with the OH-. The barrierless minimum energy path and the most favorable entrance channel have been determined by study the thermodynamic and kinetic characters of the channel with low energy barrier. The B3LYP/6-311++G** method was employed for all the geom

10. APARATO ELETROQUÍMICO PARA SISTEMA DE AQUISIÇÃO DE DADOS MULTICANAL COM RESOLUÇÃO ESPAÇO-TEMPORAL
Spatiotemporal pattern formation in reaction-transport systems takes place spontaneously when the system is kept far from thermodynamic equilibrium. Targets, reaction fronts, waves, spirals, spots and stripes are some typical examples of selforganized structuring. In electrochemical systems, monitoring spatiotemporal patterns of potential in the solid/liquid
