Toward a more effective hurricane hazard communication
Environmental Research Letters, 2020 Tropical cyclones are among the most devastating natural disasters that pose risk to people and assets all around the globe. The Saffir-Simpson scale is commonly used to inform threatened communities about the severity of hazard, but lacks consideration ...

Chemical reduction of hexavalent chromium (VI) in soil slurry by nano zero valent iron [PDF]
, 2015 The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil

Various Characterizations of Modified Weibull and Log Modified Distributions [PDF]
, 2012 Various characterizations of the well-known modifiedWeibull and log-modifiedWeibull distributions are presented. These characterizations are based on a simple relationship between two truncated moments; on the hazard function and on functions of the ...

Maximum likelihood estimation of a log-concave density and its distribution function: Basic properties and uniform consistency [PDF]
, 2009 We study nonparametric maximum likelihood estimation of a log-concave probability density and its distribution and hazard function. Some general properties of these estimators are derived from two characterizations.

Characterizations of the Exponential Distribution by Some Random Hazard Rate Sequences
Mathematics, 2022 In this paper, several characterizations for exponential distribution are derived from a new relative hazard rate measure. This measure is closely related to the concept of remaining lifetime at a random time.

Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]
, 2018 Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in
