Electron transfer from zerovalent iron (Fe0) to targeted contaminants is affected by initial Fe0 composition, the oxides formed during corrosion, and surrounding electrolytes. We previously observed enhanced metolachlor destruction by Fe0 when iron or aluminum salts were present in the aqueous matrix and Eh/pH conditions favored formation of green rusts. To understand these enhanced destruction...

background: in this study are submitted the radon concentration measurement results of four underground mines: stanterg, artana, hajvali and badovc, which are owned by trepça enterprise, kosovo. the mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. the radiation exposures caused by radon and radon daughters was determined an...

The glucocorticoid receptor (GR) and peroxisome proliferator-activated receptors (PPARs) play important roles in both physiological and pathological conditions such as cell differentiation, lipolysis, control of glucose metabolism, immunity, and inflammation. In fact, recent studies suggest that the thiazolidinedione (TZD) class of PPAR-gamma ligands, like glucocorticoids, may also be clinicall...

Let $(M,g)$ be a smooth compact Riemann surface with the multicomponent boundary $\Gamma=\Gamma_0\cup\Gamma_1\cup\dots\cup\Gamma_m=:\Gamma_0\cup\tilde\Gamma$. $u=u^f$ obey $\Delta u=0$ in $M$, $u|_{\Gamma_0}=f,\,\,u|_{\tilde\Gamma}=0$ (the grounded holes) and $v=v^h$ v=0$ $v|_{\Gamma_0}=h,\,\,\partial_\nu v|_{\tilde\Gamma}=0$ isolated holes). $\Lambda_{g}^{\rm gr}: f\mapsto\partial_\nu u^f|_{\G...

During the Miocene prominent oxygen isotope events (Mi-events) reflect major changes in glaciation, while carbonate isotope maxima (CM-events) reflect changes in organic carbon burial, particularly during the Monterey carbon isotope excursion. However, despite their importance to the global climate history they have never been recorded in shallow marine carbonate successions. The Decontra secti...

in this study ptfeco ternary alloys nanoparticles of three dimentional (3d) rhombus shapes dispersed on graphene nanosheets (ptfeco/gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (orr) in polymer-electrolyte fuel cells. a combination of analytical techniques including powder x-ray diffraction, x-ray photoelectron spectra, inductively coupled plasma-...

gamma-rays emitted from the ground surface relate to the primary mineralogy and geochemistryof the bedrock, and the secondary weathered materials. this information can contribute significantly to anunderstanding of the geochemical and pedogenetic history of a region. the main aim of this paper was to study the relationship between ground gamma-ray data and basement geochemistry in the lese catc...

BACKGROUND and aims: Primary sclerosing cholangitis is a Th1 cytokine driven disease with a poor clinical responsiveness to glucocorticoid therapy. We have previously documented elevated circulating glucocorticoid levels in cholestatic rats and in addition have noted increased hepatic expression of the Th1 cytokine interferon gamma (IFN-gamma) in a rat model of cholangitis. Therefore, we examin...

natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

We analyze the quasi-periodic oscillation (QPO) of historical light curve FSRQs PKS 0405-385 detected by Fermi LAT from August 2008 to November 2021. To identify and determine QPO signal in $\gamma$-ray curve, we use four time series analysis techniques based on frequency domains, i.e., Lomb-Scargle periodogram (LSP), weighted wavelet z-transform (WWZ), REDFIT epoch folding. The results show th...
