The design of waiting and storage areas to improve the efficiency of the marine intermodal terminals
2013
The correct sizing of storage areas in the port areas is aimed to optimizing the management of intermodal transport and to ensure efficiency and functionality to the entire port system. In this paper is proposed a simulation model for design the port storage areas taking into account many parameters like: the service time, the randomness of the arrivals process, the storage capacity in terms of TEU that can be stored (and handled) in the unit of time. The capacity of the terminal warehouse is determined by the interrelation between fixed and static parameters in the short period which are: i) the extension of the storage area; ii) the height of the overlapping batteries of container (define…
Bright spots in the darkness of cancer: A review of starfishes-derived compounds and their anti-tumor action
2019
The fight against cancer represents a great challenge for researchers and, for this reason, the search for new promising drugs to improve cancer treatments has become inevitable. Oceans, due to their wide diversity of marine species and environmental conditions have proven to be precious sources of potential natural drugs with active properties. As an example, in this context several studies performed on sponges, tunicates, mollusks, and soft corals have brought evidence of the interesting biological activities of the molecules derived from these species. Also, echinoderms constitute an important phylum, whose members produce a huge number of compounds with diverse biological activities. In…
Collective Locomotion of Human Cells, Wound Healing and Their Control by Extracts and Isolated Compounds from Marine Invertebrates
2020
The collective migration of cells is a complex integrated process that represents a common theme joining morphogenesis, tissue regeneration, and tumor biology. It is known that a remarkable amount of secondary metabolites produced by aquatic invertebrates displays active pharmacological properties against a variety of diseases. The aim of this review is to pick up selected studies that report the extraction and identification of crude extracts or isolated compounds that exert a modulatory effect on collective cell locomotion and/or skin tissue reconstitution and recapitulate the molecular, biochemical, and/or physiological aspects, where available, which are associated to the substances und…
Dal mare al museo. Il recupero di uno scheletro di stenella striata, Stenella coeruleoalba (Meyen 1833)
2022
In 2021, the Museum of Zoology “P. Doderlein” of the University of Palermo acquired a new specimen, the complete skeleton of Stenella coeruleoalba, a striped dolphin stranded in 2018 in Marinella di Selinunte, Castelvetrano (Sicily, Southern Italy). The project herein described is the result of a collaboration among the Bio-Reconstruction Laboratory of the IAS-CNR of Capo Granitola, the IZS of Palermo, the company Naturaliter and the Museum of Zoology “P. Doderlein”. In Natural History Museums, cetaceans are an excellent tool to facilitate scientific dissemination aimed at the conservation of marine biodiversity. The work herein described is presented as an example of good practices in reco…
Bioremediation of chronically oil-polluted marine sediment using beats of hydrocarbons-degrading bacteria
2015
Bioremediation is a good kind of "green biotechnology" based on the microorganisms ability to degrade hydrocarbons fractions. In this work sediment samples were collected from the industrial harbor of Priolo Gargallo (Augusta, Syracuse, Sicily - Italy), a chronically polluted area. Enrichment cultures and microbial isolation were performed. Amoung 258 bacteria and 5 consortia isolated, strain S1 (Alcanivorax borkumensis, 98%) and two consortia (PSO and PSM) showed degradation rates of ~98% for linear and polycyclic aromatic hydrocarbons (PHAs) after 10 days of incubation (25±1°C, shaking 100 g). Taxonomic analysis (16S clone libraries) of consortia showed as dominant genera hydrocarbonoclas…

Contaminated sediments from dredging activities as modern turbidites: geochemical signatures in box-core sediments from the Augusta area, Ionian Sea,…
2009
The Augusta area (SE Sicily) is one of the most industrialized and contaminated coastal environments in the Mediterranean region, having a relatively high influx of unregulated industrial effluents. Valuable sets of geochemical data (major elements and trace metals), obtained from box-core sediments collected along a transect from the Sicilian coastal zone seawards of Augusta and dated via 210Pb and 137Cs, indicated increased metal contamination (notably Hg) since ca 1940-1950, related to the industrial development of the area. Metal enrichment is considerable in the coastal sediments, being significantly in excess (for Hg and Pb) of background values estimated for the Strait of Sicily. Mor…
