Estimation of the Latent Heat Flux over Irrigated Short Fescue Grass for Different Fetches

open access: yesAtmosphere, 2021
Often in agrometeorology the instrumentation required to estimate turbulent surface fluxes must be installed at sites where fetch is not sufficient for a sector of wind directions.

XMM-Newton observations of EF Eridani: the textbook example of low-accretion rate polars [PDF]

open access: yes, 2007
Archival X-ray observations of EF Eridani obtained in a low state revealed distinct X-ray detections at a luminosity L_X ~ 2 10^{29} erg/s, three orders of magnitude below its high state value. The plasma temperature was found to be as low as $kT \loa 2$

Power Transformer Inrush Current Analysis: Simulation, Measurement and Effects

open access: yesApplied Sciences
Inrush current is still a persistent problem affecting the quality of the power system. This paper presents the theoretical aspects of this transient phenomenon, the simulation of the phenomenon for prediction purposes and its measurement in a test ...

Impact of post-field data processing on eddy covariance flux estimates and energy balance closure

open access: yesMeteorologische Zeitschrift, 2006
This study evaluates the impact of post-field data processing methods on eddy covariance flux estimates and the resulting energy balance residual. To that end, a dataset from the LITFASS-2003 field campaign was analysed using an experimental software ...

Prediction of Transformer Residual Flux Based on J-A Hysteresis Theory

open access: yesEnergies
Circuit breakers are effectively utilized for the controlled switching technique to mitigate inrush current when energizing an unloaded transformer. The core of the controlled switching technique is to obtain the appropriate closing angle based on the ...

Residual conductance of correlated one-dimensional nanosystems: A numerical approach

open access: yes, 2004
We study a method to determine the residual conductance of a correlated system by means of the ground-state properties of a large ring composed of the system itself and a long non-interacting lead.

Dust Distribution in Gas Disks. A Model for the Ring Around HR 4796A [PDF]

open access: yes, 2000
There have been several model analyses of the near and mid IR flux from the circumstellar ring around HR4796A. In the vicinity of a young star, the possibility that the dust ring is embedded within a residual protostellar gas disk cannot be ruled out. In

Use of ornamental rock residues for mould flux development [PDF]

open access: yesREM - International Engineering Journal, 2018
Abstract Ornamental rock production, such as marble and granite plates, have great importance in the southeastern region of Brazil. Its residues are composed of some compounds used in continuous casting as mould fluxes. Therefore, the aim of this article was to study these residues to formulate mould fluxes.

A large-eddy simulation exploration of the assumptions used in retrieving entrainment from a mixing diagram approach with ground-based remote sensors [PDF]

open access: yesAtmospheric Measurement Techniques
Entrainment is a crucial component of the atmospheric boundary layer (BL) moisture and heat budget. While usually thought of as only entrainment flux, entrainment within the mixed layer budget equation is really composed of two terms: the flux of a ...

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).
