The state of the art in accelerator mass spectrometry (AMS) is reviewed. The review is divided in two parts. The first covers the general methodology, followed by its specific elaborations for the commonly measured long-lived isotopes such as 10Be, 14C, 26Al, 36Cl and 129I, as well as other isotopes with emerging applications. The second part considers the very wide spectrum of applications tha...
We show that a common feature of temperature-dependent microwave absorption is the presence of absorption peaks. ac loss peaks can arise when the internal T -dependent magnetic relaxation time crosses the measurement frequency. These features are observed in the insulating (SrxCa14−xCu24O41, La5/3Sr1/3NiO4 and Y Ba2Cu3O6.0), pseudo-gap (T > Tc in underdoped Y Ba2Cu3O7−δ , Hg : 1223 and Hg : 120...

Cosmetic producers are obliged to guarantee the safety and stability of their products. The current legal regulations are based on the European Union Directive (1223/2009) of 30 November 2009. The main aim of the directive is to formulate criteria of safety of a cosmetic product and requirements that it must meet to be placed on the market. A new cosmetic product is subjected to thorough invest...
