Stefan problems for the diffusion-convection equation with temperature-dependent thermal coefficients
(Pergamon-Elsevier Science Ltd, 2021-09)
Different one-phase Stefan problems for a semi-infinite slab are considered, involving a moving phase change material as well as temperature dependent thermal coefficients. Existence of at least one similarity solution is ...
Backward adaptive brightness temperature threshold technique (BAB3T): A methodology to determine extreme convective initiation regions using satellite infrared imagery
(Molecular Diversity Preservation International, 2020-01)
Thunderstorms in southeastern South America (SESA) stand out in satellite observations as being among the strongest on Earth in terms of satellite-based convective proxies, such as lightning flash rate per storm, the ...
Synoptic forcing associated with extreme precipitation events over Southeastern South America as depicted by a CORDEX FPS set of convection-permitting RCMs
(Springer, 2021-01)
Southeastern South America (SESA) stands out as a remarkable region of occurrence of deep convection. This is mainly due to the proximity of the Andes, which eventually determine their magnitude and intensity. In this work, ...
The effects of small-scale convection in the shallow lithosphere of the North Atlantic
(Wiley Blackwell Publishing, Inc, 2021-07)
Curie point depth can be used as a proxy for plate temperatures. Data from the North Atlantic (10°-50°N) are used here to determine if the observed oscillations and patterns in Curie depths could be a subproduct of small-scale ...
Modifications in the gamma dose rate in air due to downward and lateral mobility of 137Cs in the soil
(Elsevier, 2019-03)
137Cs can be an important environmental contaminant due to fallout from nuclear reactor accidents and atomic weapons testing. Its contribution to the air gamma dose rate at 1 m height above contaminated ground depends on ...
Determining convective heat transfer coefficient during sterilisation of canned evaporated whole milk
(Elsevier Science, 2010-12)
The effect of retort temperature, rotation speed, headspace and radius of rotation on mean convective heat transfer coefficient during sterilisation of canned evaporated whole milk was studied. The mean total solids content ...
Study of Drying Kinetics and Functional Properties of Dietary Fiber Concentrates from Papaya by-Products
(Indian Society of Education and Environment, 2018-10)
Objectives: To analyze the drying kinetics and functional properties of Dietary Fiber Concentrates (DFCs), produced from papaya by-products (pulp or peel) dehydrated by microwave or hot air convection at 40°C. Methods/Statistical ...
Analysis of long-term potential gradient variations measured in the Argentinian Andes
(Elsevier Science Inc., 2021-01)
Continuous measurements of the potential gradient are being recorded at the CASLEO astronomical observatory near to the Andes Mountain of Argentina, since 2010 (Latitude: 31°47.88′S, Longitude: 69°17.7′W, Altitude: 2552 ...
Modelling convective drying of foods: A multiphase porous media model considering heat of sorption
(Elsevier, 2019-12)
This study presents a theoretical and numerical analysis to derive a multiphase model of heat and mass transfer for low intensity/temperature convective drying of hygroscopic porous materials, with focus on food products. ...
Convective heat transfer coefficients of open and closed Cryotop ® systems under different warming conditions
(Academic Press Inc Elsevier Science, 2018-10)
The warming of cryopreserved samples supported by small volume devices is governed by heat transfer phenomena which are mathematically described by the solution of the transient heat conduction partial differential equations; ...
