Samplers based on the diffusive gradients in thin films for organics (o-DGT) were developed and applied Brazilian aqueous matrices determination of four emerging contaminants (EC): 4-octylphenol, 4-nonylphenol, triclosan, bisphenol A. The OASIS HLB resin used as binding phase presented a high sorption capacity extraction associated with sonication, using mixture acetonitrile methanol (2:1, v v-...

The results this indicate that expertise director (in field taxation, tax consultant profession frequency board meetings have significant avoidan...

Ionic liquids have attracted a large amount of interest in the past few years. One approach to better understand their peculiar nature and characteristics is through the analysis of their surface properties. Some research has provided novel information on the organization of pure ionic liquids at the vapor-liquid interface; yet, a systematic study on the surface properties of mixtures of ionic ...

Organic compounds resulting from the decomposition of organic amendments are used in the remediation of trace element (TE) contaminated soils. The mobility, phytoavailability and soil exposure intensity of molybdenum (Mo), chromium (Cr), zinc (Zn), copper (Cu), Cobalt (Co) and Arsenic (As) were evaluated in the phytoremediation of contaminated technosols after the addition of two organic matter...

Green tea (GT), through its antioxidant properties, may be useful to treat or prevent human diseases. Because several lines of evidence suggest that oxidative stress contributes to the pathogenesis of diabetic nephropathy, we tested the hypothesis that GT prevents diabetes and hypertension-related renal oxidative stress, attenuating renal injury. Spontaneously hypertensive rats (SHR) with strep...

Abstract. This two-part paper examines two approaches for mesh adaptation, using combinations of a posteriori error estimates and domain decomposition. In the first part, we consider a domain decomposition method applied to the generalized Stokes problem, with mesh adaptation in each subdomain using the a posteriori local error estimator as adaptation indicator. We apply domain decomposition wi...

Abstract Background The phosphorus (P) stocks of arable subsoils not only influence crop production but also fertilizer P sequestration. However, the extent this is largely unknown. This study aimed to (i) determine sequestration with soil depth, (ii) analyze speciation after long-term fertilization, and (iii) compare tests in predicting yields. We analyzed four trials Germany a depth 90 cm. Tr...
