les schoenites chromates sont parfaitement isotypes : entre elles et avec les sulfates correspondants , ils cristallisent tous dans le systeme monoclinlque p2 /c , avec deux motifs par maille . une etude thermique analogue a ete effectuee sur les chromates doubles : m mg(cro ) , 6h 0 ou m =rb ou cs , la deshydration de ces sels conduit aux tetrahydrates , aux sels anhydres qui se decomposent ap...

sels, are employed as surveillanceorganisms for marine pollutants (artificially produced radionuclides, petroleum hydrocarbons, metals, and chlorinated hydrocarbons used industrially and as biocides in coastal waters). Varying degrees of contamination in US coastal waters have been indicated by the elevated levels of these substances in the soft parts of bivalves. [The Sd® indicates that this p...

Two different characterizations of self-dual aggregation operators are available in the literature: one based on C(x, y) = x/(x + 1 − y) and one based on the arithmetic mean. In this contribution, we fit the existing approaches into a more general framework and characterize N -invariant aggregation operators, with N an involutive negator. Special attention is drawn to the equivalence classes th...

INTRODUCTION Solar ultraviolet exposure is the main cause of skin damage by initiation of reactive oxygen species (ROS) leading to skin collagen imperfection and eventually skin roughness. This can be reduced by proper revitalization of skin enhancing younger and healthier appearance. AIM To evaluate the skin facial revitalization effect of a cream formulation containing the Moringa oleifera ...

Background and study aims Single-incision needle-knife (SINK) biopsy is a diagnostic method for acquiring tissue samples for subepithelial lesions (SELs). A single linear incision is made in the overlying mucosa and tissue samples are obtained by passing conventional biopsy forceps through the opening and deep into the lesion. The aim of this study was to describe the efficacy and safety of thi...
