A new fully microwave-assisted liquid sample introduction system (MASIS) is presented and evaluated in Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The device employs a single TM010 microwave cavity for the simultaneous aerosol generation and desolvation. The different experimental requirements…

The aim of this paper is to explore the reasons that lead to information systems outsourcing in the largest Spanish firms. Our paper takes as its starting point the previous literature on information systems and tries to analyse if those…

The traditional games of children are the maximum exponent of a people’s culture of play, and though these games are sometimes derived from adult ceremonies, in spirit they belong to the world of children. Most authors assume that games depend…

A set is called Motzkin decomposable when it can be expressed as the Minkowski sum of a compact convex set with a closed convex cone. The main result in this paper establishes that a closed convex set is Motzkin decomposable…

The thermal degradation of samples of used cotton fabrics has been investigated using thermogravimetric analysis (TGA) between room
temperature and 700 °C. Experiments were carried out with about 5 mg of sample in three different atmospheres: helium, 20% oxygen in…
