The 9 Azores islands are located in the North Atlantic Ocean, about 1500 km from Europe. The vascular plant flora, consisting of 1002 taxa, was characterized using a database. Biogeographic and historic criteria were used to categorize the taxa as indigenous (31%) and non-indigenous (69%). The proportion of non-indigenous vascular plant taxa is higher than(More)
The series of quinoline derivatives were prepared. The synthetic approach, analytical, and spectroscopic data of all synthesized compounds are presented. All the prepared derivatives were analyzed using the reversed-phase high performance liquid chromatography (RP-HPLC) method for the lipophilicity measurement. In the present study, the correlation between(More)
A random survey of non-indigenous plants was performed on the nine islands of the Azores Archipelago, including 529 one square km plots, corresponding to about 20% of the land surface. The number of sampling plots varied from 12 for Corvo Island to 136 for São Miguel, while the number of sampled taxa per island varied between 152 and 365. The percentage of(More)
The introduction of interaction technology in museum settings requires special care in different aspects including the relations with the different participants (public, artists, and curators), and the ability of the technology to provide rewarding experiences over extended periods of time for a demanding audience. This paper describes a hardware and(More)
The aim of this study was to assess the impact of anthropogenic disturbance on the partitioning of plant communities (species spectra) across a landcover gradient of community types, categorizing species on the basis of their biogeographic, ecological, and conservation status. We tested a multinomial model to generate species spectra and monitor changes in(More)
PAL is a glucose/mannose-specific lectin isolated from Pisum arvense seeds. Previously, we demonstrated the capacity of other leguminous lectins to induce oedema formation and neutrophil stimulation. To investigate the potential pro-inflammatory activity of PAL, we have studied its ability to induce neutrophil migration into peritoneal cavities of rats and(More)
Osteoporosis drugs are prescribed to prevent fragility fractures, which is the principal aim of the management of osteoporosis. However, if fracture does occur, then it is also important to promote a fast and uneventful healing process. Despite this, little is known about the effect of osteoporosis drugs on bone healing in humans. Strontium ranelate is an(More)
Toxicity tests with Vibrio fischeri, Daphnia magna, and Lemna minor were used to evaluate acute and chronic toxicity of cork-boiling wastewaters and correlation analysis was performed with physicochemical parameters. Acute toxicity values (EC(50)) ranged from 2.3% to 24.2% in the Microtox test and from 4.4% to 29.5% in the Daphnia test. According to these(More)
The series of quinaldine derivatives were prepared, some of them by means of novel synthetic methods. The synthetic approach, analytical and spectroscopic data of all newly synthesized compounds are presented. The prepared compounds were tested for their in vitro antifungal activity as well as for their photosynthesis-inhibiting activity (the inhibition of(More)
We assessed the effectiveness of very high spatial resolution IKONOS imagery for mapping a top invasive woody plant, Pittosporum undulatum, in a Protected Area in S.Miguel Island. We developed a segmentation-based classification scheme. A strong separability between most important land cover classes and a high accuracy in supervised classification maps was(More)
