While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...

A discussion of several exotic models and how well they are able to describe the data, with particular emphasis on atmospheric neutrinos.

Background Only alimited number of studies have evaluated the association between phototherapy-treated neonatal jaundice and the development of atopic dermatitis (AD) in the early childhood. In this context, the present study is aimed to assess the relationship between the AD development in the childhood and the history of phototherapy in the case of neonatal jau...

In this paper, a newly proposed analytical scheme by the authors namely the improved di erential transform method is employed to provide an explicit series solution to the Thomas Fermi equation. The solution procedure is very straightforward, requiring merely elementary operations together with di erentiation, and ends up in a recursive formula involving the Adomian polynomials to a ord the unk...

In a recent paper, Peláez and Ynduráin evaluate some of the low energy observables of ππ scattering and obtain flat disagreement with our earlier results. The authors work with unsubtracted dispersion relations, so that their results are very sensitive to the poorly known high energy behaviour of the scattering amplitude. Indeed, their calculations mainly illustrate the fact that the most impor...

In this study, a temperature-dependent of the dispersion coefficients is calculated from equation state.The Lennard-Jones LJ (12-6-3) effective pair potential function and simple thermodynamic argumentwith the input PVT data of liquid metals are used to calculate the dispersion coefficients. The dispersioncoefficients ( , , ) 3 6 12 C C C are found to be a linear function of 1/T1+α , where T is...

Abstract. Equal channel angular pressing (ECAP) as a severe plastic deformation (SPD) technique was employed for consolidation of AZ31 magnesium chips. The chips were consolidated at temperature 300 °C following ECAP route A up to two passes. optical and scanning electron micrographs reveal that have taken place the quality improves with number passes hence total imposed strain. Vickers hardnes...

Background: Recent studies have shown that oxidative stress (OS) is the most important indicator in the pathogenesis of Alzheimer's disease (AD), but the results in previous studies are conflicting. This study aimed to assess the plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as DNA oxidative damage marker and total antioxidant capacity (TAC) in patients with AD versus control group. ...
