The contribution of hyperspectral remote sensing to identify vegetation characteristics necessary to assess the fate of Persistent Organic Pollutants (POPs) in the environment

open access: yesAnnals of Geophysics, 2006
During recent years hyperspectral remote sensing data were successfully used to characterise the state and properties of vegetation. The information on vegetation cover and status is useful for a range of environmental modelling studies.

Evaluation of Machinery Readiness Using Semi-Markov Processes

open access: yesApplied Sciences, 2020
This article uses Markov and semi-Markov models as some of the most popular tools to estimate readiness and reliability. They allow to evaluate of both individual elements as well as entire systems—including production systems—as multi-state ...

A Revisit to the Pretargeting Concept—A Target Conversion

open access: yesFrontiers in Pharmacology, 2018
Pretargeting is often used as a tumor targeting strategy that provides much higher tumor to non-tumor ratios than direct-targeting using radiolabeled antibody.

Measurement of polarization curve and development of a unique semi-empirical model for description of PEMFC and DMFC performances [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2011
In this study, a single polymer electrolyte membrane fuel cell (PEMFC) in H2/ /O2 form with an effective dimension of 5 cm5 cm as well as a single direct methanol fuel cell (DMFC) with a dimension of 10 cm10 cm were fabricated.

Application of Hansen solubility parameters in the eutectic mixtures: difference between empirical and semi-empirical models

open access: yesScientific Reports
Hansen Solubility Parameters (HSPs) are widely used as a tool in solubility studies. Given the variety of existent approaches to predict these parameters, this investigation focused on estimating the HSPs of a set of Natural Deep Eutectic Systems (NADES),
