15. Effect of season and irrigation on the chemical composition of Aloysia triphylla essential oil
ABSTRACT Aloysia triphylla is an aromatic plant used in several industrial sectors, owing to the chemical properties of its essential oil. Biosynthesis of organic compounds is influenced by the growth conditions. As such, temporal and spatial variation affect the chemical composition of essential oils. We hypothesized that: i) the chemical composition of A.

24. Caracterización del comportamiento frente a la corrosión en soldaduras de recargue de aceros inoxidables superdúplex
ABSTRACT Superduplex stainless steels have a dual structure constituted approximately by 50% of ferrite and 50 % of austenite. This fact produces a good combination of mechanical properties and corrosion resistance. Thanks to these features their use is growing, mainly in the industries of paper, chemical, gas and oil. Surfacing welding is used for the manuf
