Uso delle tecniche GNSS a supporto dei rilievi di infortunistica stradale

In the context of scientific research developed in recent years by DICAM, University of Palermo, a trend that is particularly interesting and multidisciplinary concerning the use of GNSS techniques in NRTK for applications of road accidents. The detections of the information relating to the left road today are conducted with standardized mode between those of local police; regarding the real relief it is realized with triangulation techniques, with the aid of manual instrumentation consists casters metrics in plastic or steel wires. The GNSS techniques in NRTK lend themselves well to this type of survey, the high information content and to manage different metadata (maps, coordinates, photo…

Stock assessement and management by restocking of Melicertus kerathurus (Forskäl, 1775) in the shallow coastal waters at Selinunte

From 1998 to 2010, monitoring was performed on the catch and fishing effort of Melicerctus kerathurus by the artisanal fleet based at the port at Marinella di Selinunte which operates in the wide gulf between Capo San Marco and Capo Granitola along the southwestern coast of Sicily. In 2004, a repopulation experiment with Melicerctus kerathurus post-larvae raised in an aquaculture plant from wild indigenous breeders was carried out in this area. The catch and cpue, in both number of specimens and in yield, were practically doubled in 2005. From 2006, catch and cpue returned to levels observed in the years prior to 2005. With the exception of 2004 and 2005, the stock of Melicerctus kerathurus…

Bus Speed Estimation By Neural Networks To Improve The Automatic Fleet Management

In the urban areas, public transport service interacts with the private mobility. Moreover, on each link of the urban public transport network, the bus speed is affected by a high variability over time. It depends on the congestion level and the presence of bus way or no. The scheduling reliability of the public transport service is crucial to increase attractiveness against private car use. A comparison between a Radial Basis Function network (RBF) and Multi layer Merceptron (MLP) was carried out to estimate the average speed, analysing the dynamic bus location data achieved by an AVMS (Automatic Vehicle Monitoring System). Collected data concern bus location, geometrical parameters and tr…

SINDROME DA ENCEFALOPATIA POSTERIORE REVERSIBILE: TEMIBILE COMPLICANZA IN CORSO DI MAS DA AIG SISTEMICA

Background: La sindrome da encefalopatia posteriore reversibile (PRES) è un disordine secondario a diverse condizioni cliniche, caratterizzato da cefalea acuta o subacuta, nausea, vertigini, alterazioni della coscienza, convulsioni, disturbi visivi transitori, emorragia retinica ed edema del nervo ottico. Alla RMN si riscontra edema vasogenico nell'emisfero cerebrale posteriore e talvolta aree necrotiche. Riportiamo il caso clinico di una paziente con sindrome da attivazione macrofagica (MAS) secondaria ad AIG sistemica che ha sviluppato una PRES. Caso Clinico: Una adolescente di 11 anni giunge alla nostra osservazione per comparsa di febbre persistente da 10 gg. Durante la degenza è stata …

Population size and breeding performance of the Lanner Falcon Falco biarmicus in Sicily: conservation implications

Capsule: We report a significant reduction in population size and breeding success for the Lanner Falcon Falco biarmicus in Sicily, its biggest stronghold in Europe, since the latest coordinated survey. Aims: To provide updated information on current population size of Lanner Falcon in Sicily and to compare breeding parameters with those obtained in previous studies. Methods: We performed an intensive coordinated field survey and literature review of breeding success parameters across the species range. Results: Overall, we monitored 126 territories throughout Sicily where the species had been reported in the last 15 years. Lanner Falcons were present only in 60 of them. Mean nest productiv…

I DECAPODI BERSAGLIO DELLA FLOTTA ARTIGIANALE TRA CAPO GRANITOLA E CAPO SAN MARCO (COSTA SUD OCCIDENTALE SICILIANA)

LO STUDIO DEI POTENZIALI EVOCATI VISIVI E UDITIVI IN PAZIENTI CON MALATTIA DI KAWASAKI: CASISTICA DELLA CLINICA PEDIATRICA DI PALERMO

La Malattia di Kawasaki (MK), una vasculite sistemica con elettivo interessamento coronarico, può portare a complicanze a carico di diversi distretti quali fegato, reni, polmoni, intestino, occhi, cute, SNC. La sordità neurosensoriale è descritta in casi sporadici e può essere persistente. Lo studio dei potenziali evocati uditivi (ABR) e visivi (PEV) è metodica efficace per identificare, in assenza di sintomi uditivi e/o visivi, alterazioni degli stessi. Abbiamo studiato 52 pazienti (31 M; 21 F; età: 3 mesi-10 anni) con MK mediante PEV e ABR, sia in fase acuta di malattia che durante il follow-up ed abbiamo correlato i risultati dei potenziali con i parametri clinici, la forma della MK (tip…

LA PANCREATITE ACUTA: UNA TEMIBILE COMPLICANZA IN CORSO DI PORPORA DI HENOCHSCHONLEIN. CASISTICA DELLA CLINICA PEDIATRICA DI PALERMO

Introduzione: La: porpora di Schönlein-Henoch (PSH) è la vasculite con più alta incidenza in età pediatrica. Le manifestazioni cliniche classiche sono: porpora palpabile, tumefazione articolare con artralgie, possibile dolore addominale con sangue occulto positivo o franca rettorragia, in casi con particolare severità, è possibile riscontrare addome acuto, insufficienza renale, proteinuria sino alla sindrome nefrosica. Rara è la pancreatite acuta che può rendere particolarmente drammatico il quadro clinico talvolta in modo irreversibile. La diagnosi viene confermata sia dal dosaggio di amilasi pancreatica, lipasi, sia dalla RMN addominale. La terapia prevede la somministrazione di steroidi …

Effect of the presence of the shore crab, Carcinus maenas, on the burrowing behaviour and clearance rate of the common cockle, Cerastoderma edule

Bivalves demonstrate various morphological and behavioural adaptations to reduce the risk of being attacked by predators. This paper examines how the presence of the crab Carcinus maenas (L.), a natural predator of the cockle Cerastoderma edule (L.), affects its burrowing depth and clearance or feeding rate. Cockles were placed in experimental tanks and treated with three levels of predatory disturbance: (1) unfed crab loose inside the tank, (2) unfed crab inside a cage suspended in the water column and (3) no crab present. Cockles’ burrowing depth was measured in two sediment types: mud and sand. Cockles burrowed more deeply in treatments with no crabs. Burrowing depth in sand was signific…

RHEUMATHOLOGIC DISEASES IN ADOLESCENCE: PSYCHOLOGICAL PROFILE OF A DIFFICULT AGE

Background: Chronic disease significantly interfere with the quality of life at every age, expecially in a period of life characterized by the need to assume a role in the society and the research of a specific identity. The personal image is often destroyed by the disease, the long term sequelae of pharmacological treatment. Adolescents are frequently obligated to quit many possibilities of experience with peers. Objectives: We realized a plurispecialistic approach to adolescents with rheumatologic diseases, with the figures of neuropsychiatric, psychologists, rheumatologists, endocrinologists, to give an answer to the complex requests of these patients. Methods: We evaluated 20 patients w…
