Estimating daily global radiation from common meteorological variables in a humid subtropical environment
(Univ Federal Mato Grosso, 2019-11-01)
Knowledge of solar potential is essential in the design and simulation of systems that convert solar radiation in electric power or available heat in fluids, as well as in agricultural studies focused on irrigation management ...
Scalar quasinormal modes of nonlinear charged black holes in Rastall gravity
(Iop Publishing Ltd, 2019-12-01)
In this paper, the scalar quasinormal modes of nonlinear charged black hole metrics in Rastall gravity is investigated. The electromagnetic tensor presented in the background spacetime possesses a power-law form, and the ...
Quantile graphs for EEG-based diagnosis of Alzheimer’s disease
(2020-06-01)
Known as a degenerative and progressive dementia, Alzheimer’s disease (AD) affects about 25 million elderly people around the world. This illness results in a decrease in the productivity of people and places limits on ...
Comparison of RF and Pulsed Magnetron Sputtering for the Deposition of AZO Thin Films on PET
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2020-01-01)
AZO thin films (around 200 nm thick) were grown on polyethylene terephthalate (PET) at room temperature. The plasma was activated using a 13.56 MHz (RF) or a 15 kHz pulsed (PMS) source at a power of 60 W. Optical reflection ...
An integrated approach to obtain xylo-oligosaccharides from sugarcane straw: From lab to pilot scale
(2020-10-01)
Sugarcane straw (SS) is a widely available agricultural processing feedstock with the potential to produce 2nd generation bioethanol and bioproducts, in addition to the more conventional use for heat and/or electrical power ...
Head lettuce production and nutrition in relation to nutrient solution flowProdução e nutrição da alface americana em função da vazão da solução nutritiva
(2020-01-01)
The optimum flow rate of nutrient solution in hydroponic system can better nourish the crops, allowing healthy and faster growth of lettuce. However, flow also interferes with electric power consumption, so further researches ...
Role of the plasma activation degree on densification of organosilicon films
(2020-01-01)
The possibility of controlling the density of organosilicon films was investigated by tuning the plasma activation degree without providing extra energy to the structure, as usually reported in the literature. For this ...
Metallic behavior in STO/LAO heterostructures with non-uniformly atomic interfaces
(2020-09-01)
The search for new and low-power switching devices involving the integration of semiconductor thin films is of interest, and has led to renewed research because such devices may exhibit innovative properties. Here, we ...
Synthesis of Viscoelastic Behavior Through Electromechanical Coupling
(2020-01-01)
Background: Viscoelasticity is a property of materials that present elastic and viscous behavior when they experience deformation. The simplest model that can represent the viscoelastic behavior is generally called the ...
Acoustic fields of acid suspensions containing cassava bagasse: Influence of physical properties on acoustic attenuation
(2021-06-01)
The effects produced by high-intensity ultrasound application during the acid pretreatment of biomass can enhance its later conversion into bioethanol. Therefore, it is interesting to evaluate how residues, such as cassava ...
