<p>In shale gas-producing countries, soil, and groundwater contamination due to surface spills associated with hydraulic fracturing operations is one of the most worrying problems that arise, since its elimination not easy or cheap carry out, effects persist for many years. Thus, this study identifies environmental health risks extraction unconventional gas. The was carried out based on a...

Boundary environmental pollution and pollution spillovers are important issues for improving the water quality of trans-boundary rivers. This paper explores the empirical effects of the evolution of the pollution reduction mandates on boundary pollution by studying the change of water pollution levels (as proxied by pH, BOD, COD and NH3-N) of key state monitoring stations from 2004 to 2014. The...

In the context of mod-Gaussian convergence, as defined previously in our work with J. Jacod, we obtain asymptotic formulas and lower bounds for local probabilities for a sequence of random vectors which are approximately Gaussian in this sense, with increasing covariance matrix. This is motivated by the conjecture concerning the density of the set of values of the Riemann zeta function on the c...

Some positivity conjectures are made generalizing known results for Gaussian posets. For a sequence of non-negative integers ~ a = (a 1 ; a 2 ; ; a n), and a non-negative integer m, MacMahon 1, p. 137] considered the rational function of q,

V r /2 t,p/2 is a scaled version of Gaussian measure with r p if 1 < p < 2 and r p ′ if 2 < p < ∞ with 1/p 1/p′ 1. Conversely if F is a holomorphic function which is in a “slightly” smaller space, namely L C, V r/2 t,p/2 , then it is shown that there is a function f ∈ L R, ρ such that e−tHf F. However, a single necessary and sufficient condition is obtained for the image of L2 R, ρp/2 under e−t...

The aim of this study was to estimate the population burden of respiratory diseases in the Zasavje region of Slovenia that can be attributed to outdoor air pollution in order to gain relevant grounds for evidence based public health activities. In 2008, 981 schoolchildren (age 6 to 12 years) were observed in a prevalence study. The prevalence of chronic respiratory diseases (CRD) and frequent a...

Tropical algebraic geometry offers new tools for elimination theory and implicitization. We determine the tropicalization of the image of a subvariety of an algebraic torus under any homomorphism from that torus to another torus.

Heavy metal pollution management is a global environmental problem that poses great threat to the ecological environment. Adsorption and biomineralization are considered be two most promising heavy remediation techniques among numerous available ones. In this work, combined removal system was constructed employing adsorption of montmorillonite mineralization carbonate mineralizing bacteria expa...
