SUPERCRITICAL CO2 EXTRACTION OF ESSENTIAL OIL FROM MYRTUS COMMUNIS BERRIES
No full textProceedings (senza ISBN) della Conferenza "CISF99 - Fifth Italian Conference on Supercritical Fluids and their Applications", Garda (VR), 13-16 giugno 1999. -
An investigation of the application of supercritical carbon dioxide extraction to the production of essential oils from myrtle berries has been made to verify that the properties of the oil remain essentially unchanged when this technique is applied. Yield and composition (related quantity of the main components) have been used for comparing the performance of the supercritical extraction and hydrodistillation. The presence of a high molecular weight compound (a dione) in the extract and a higher yield of essential oil are the main evident differences between the supercritical extraction and the traditional hydrodistillation
Analysis of behaviour of costruction under impact and explosions: Approaches for structural analysis, from material modeling to structural responcse
No full textExperimental analysis of the UHPFRCs behavior under tension at high stress rate
No full textThe results of experimental investigation on the tensile response of UHPFRCs under high stress rates are presented. The dynamic tests are carried out on notched cylindrical specimens using a Split Hopkinson Tensile Bar. The material behavior of UHPFRC and its matrix (UHPC) is investigated at four high stress rates (from 400 to 1000 GPa/s). The rate sensitivity of the UHPFRC and UHPC in tension is evaluated in terms of Dynamic Increase Factor (DIF) of their peak strength. Finally, two different coring orientations on UHPFRC having 3, 4 and 5% fiber content are considered
