1. Should ethanol be considered a treatment for COVID-19?
Abstract This paper describes the analysis of the effects of a frequency selective surface (FSS) on the characteristics of a microstrip line fed antenna with a bow-tie slot in the ground plane for operation in the frequency range 1 to 10 GHz. The use of the FSS is proposed to miniaturize the antenna structure and increase the number of resonance frequencies

2. A Conceptual Approach to the -ING Construction: Aspects of Radiality and Subjectification
Abstract: The -ING construction has a number of uses in the English language, and teaching it to speakers of other languages poses some challenges, as learners tend to interpret the construction as a verbal one, in the progressive aspect, which is only one part of the picture. Bearing this in mind, we have developed a corpus-based research into the form-mean

4. A Forecasting Tool for Predicting Australia's Domestic Airline Passenger Demand Using a Genetic Algorithm
ABSTRACT: This study has proposed and empirically tested for the first time genetic algorithm optimization models for modelling Australia's domestic airline passenger demand, as measured by enplaned passengers (GAPAXDE model) and revenue passenger kilometres performed (GARPKSDE model). Data was divided into training and testing datasets; 74 training datasets

5. Temporal variation in population structure of the isopod Urobopyrus processae Richardson, 1904 (Isopoda: Bopyridae) infesting the branchial chamber of the night shrimp Ambidexter symmetricus Manning and Chace, 1971 (Decapoda: Processidae)
ABSTRACTCaridean shrimps are often infested by ectoparasites from the isopod family Bopyridae. Urobopyrus processae is a widespread species of bopyrid parasitizing the branchial (gill) chambers of members of the caridean family Processidae, including Ambidexter symmetricus. We examined hypotheses on differential infestation based on gender, castration of the

6. Morphological and molecular characterisation of Heliconema hainanensis sp. nov. (Spirurina: Physalopteridae) from congers in the South China Sea, with a key to the species of Heliconema
Heliconema hainanensis sp. nov. collected from Uroconger lepturus (Richardson) (Anguilliformes: Congridae), Muraenesox cinereus (Forsskål) and Congresox talabonoides (Bleeker) (Anguilliformes: Muraenesocidae) in the South China Sea was described using light and scanning electron microscopy. The new species differs from its congeners by the following morphol

7. Wall effects on the cross-buoyancy around a square cylinder in the steady regime
The effects of blockage ratio on the combined free and forced convection from a long heated square obstacle confined in a horizontal channel are investigated in this work. The numerical computations are performed in the steady regime for Reynolds number = 1 - 30, Richardson number = 0 - 1 for blockage ratios of 0.125 and 0.25 for the fixed Prandtl number of

8. Quasi-neutrality and local thermodynamical equilibrium in atmospheric presure arc discharges
The atmospheric pressure Tungsten Inert Gas (TIG) arc plasma in argon is studied combining results from emission spectroscopy temperature maps with composition data and transport parameters available from literature. Two arc currents are considered and maps are obtained for the Debye number, the number of particle in the Debye sphere, which shows values of t

9. Characterization and recovery of alfa and beta amylases enzymes by expanded bed adsorption systems / Caracterização e recuperação das enzimas alfa e beta - amilases em sistema de adsorção em leito expandido
Aiming to development of new technologies, in this work a and b-amylases recovery from maize (Zea mays) malt by expanded bed adsorption (EBA) was studied in order, to aggregate value to the maize culture which is diffused into our Country. Thus, the optimization of the manufacture steps of maize malt, since the germination (changing the time) until the dryin

10. Balanço de energia e evapotranspiração de cafezal adensado em crescimento sob irrigação localizada. / Energy balance and evapotranspiration in a high density young coffee under located irrigation.
The objectives of this study were to evaluate the magnitude of global evapotranspiration (ETc) in a high density young coffee crop (3.5mx0.9m) under drip irrigation, the ETc partition considering hedgerows and interrows, and the partition of the available radiant energy between sensible and latent heat fluxes. The experiments were conducted from September 20
