Mercury (Hg) speciation and partitioning have been investigated in a fluid mud profile collected in the high turbidity zone of the Gironde estuary. The formation of the fluid lens generates local and transient oxic-anoxic oscillations following the sedimentation-resuspension tidal cycles under a specific hydrodynamic regime. The total Hg concentration, ranging from 5 to 190 nM, increases with S...

Abstract -A complex-valued functions that are univalent and sense preserving in the unit disk U can be written in the form ( ) ( ) ( ) f z h z g z   , where U(z) and g(z) are analytic in. We will introduced the operator D which defined by convolution involving the polylogarithms functions. Using this operator, we introduce the class HP(,, n) by generalized derivative operator of harmonic un...

This study aims to investigate the influence of treated wastewater (TWW) on hydraulic performance drip irrigation emitters. A field experiment was conducted in order test two types online emitters, a low pressure (LP) and standard (SP), at different working pressures (0.25 bar, 0.50 1.00 bar) using TWW. The emitters were initially evaluated laboratory for discharge exponent (X), coefficient (Kd...

The transport and prediction of hexavalent chromium (Cr(VI)) contamination in “slag–soil–groundwater” is one with many uncertainties. Based on the column experiments, a migration model for Cr(VI) slag–soil–groundwater system was investigated. hydraulic conductivity (Kt), distribution coefficient (Kd), retardation factor (Rd), other parameters were estimated laboratory. Combining these available...

Objective: Kawasaki disease (KD), an acute febrile disease that induces systemic vasculitis in infants, has been proposed by Awaya and Sahashi in 2003 to be epidemiologically linked with pollen exposure. In this report, seasonal variation patterns of the monthly development of KD in 5,917 patients (Pt.) in Kanagawa, Japan were compared with the monthly pollen release numbers (Nos.) from 1991 to...

background: one of the important aspects of equity in health is equality in the distribution of resources in this sector. the present study aimed to assess the distribution of hospital beds in shiraz in 2014.   methods: in this retrospective cross-sectional study, the population density index and fair distribution of beds were analyzed by lorenz curve and gini coefficient, respectively. descrip...

The soil sorption coefficient (Kd) of glyphosate mainly controls its transport and fate in the environment. Laboratory-based analysis Kd is laborious expensive. This study aimed to test feasibility visible near-infrared spectroscopy (vis–NIRS) as an alternative method for estimation at a country scale compare accuracy against pedotransfer function (PTF). A total 439 soils with wide range values...

Various radionuclides including fission products and heavy nuclides were released into the environment during Fukushima Daiichi Nuclear Power Station (FDNPS) accident. The dissolution followed by migration of deposited Cs, Sr U on soils could take place to local environment. Therefore, it is necessary determine sorption-desorption coefficients in soil-water system around FDNPS from a viewpoint....
