Multi-elemental analysis of commercial wheat flours by ICP-MS triple quadrupole in function of the milling degree.

This preliminary study is focused on an elemental analysis of 60 samples of different commercial grains' flour, including various typologies of refined product, researching transition metals and trace elements. All the samples were first digested with a microwave digestion system and then analyzed by a triple quadrupole (TQ) inductively coupled plasma mass spectrometer (ICP-MS-QQQ) located in a Clean Room ISO class 6. The minimum value of most of the elements (Li, Be, Na, Ca, V, Cr, Mn, Fe, Co, Ni, Zn, Ga, As, Se, Rb, Sr) are in the wheat flour "00" type and in the wheat flour "0" type (B, Na, Mg, Al, Cu, Ag, Cd, In, Cs, Pb, Bi).

[Torsione di punta indotta dalla cocaina: un caso clinico.].

Riassunto. La torsione di punta (TdP) è una tachicardia ventricolare polimorfica con una caratteristica torsione sinusoidale del complesso QRS attorno alla linea di base. Si differenzia da altre forme di tachicardia ventricolare per le sue caratteristiche morfologiche, per il meccanismo sottostante e le modalità di terapia.

Parchment processing and analysis: Ionizing radiation treatment by the REX source and multidisciplinary approach characterization.

Library material, and thus parchment, is frequently subjected to bio-deterioration processes caused by microorganisms. Fungi and bacteria cause alterations in the parchment inducing, in some cases, even the partial detachments of the surface layer and the loss of any text present on it. An important contribution to disinfection of the cultural heritage artefacts is given by the use of ionizing radiation.
