The therapeutic of sesquiterpene lactones (SLs) as natural products for pharmaceutical development has gained extensive interest costunolide (chemical name: 6E,10E,11aR-6,10-dimethyl-3-methylidene-3a,4,5,8,9,11a-hexahydrocyclodeca[b]furan-2-one) used popular herbal remed...

Objective: To evaluate water consumption in ornamental plants (geranium, gazania and petunia) two substrates with different particle sizes (fine coarse) of tezontle peat moss, through a suction irrigation system, which uses porous capsules as emitters. Design/methodology/approach: The experimental design was complete randomized blocks, six treatments (three species substrates) four repetitions ...

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. The above mentioned roofing systems were developed and tested at the University of Lleida, in Spain...
