Data assimilation of temperature and salinity profiles in the Adriatic Sea regional model
Anita GREZIO,Nadia PINARDI
Acta Adriatica , 2006,
Abstract: Temperature and salinity data collected during the October 2002 - October 2003 period have been assimilated into a version of the Princeton Ocean Model implemented over the entire Adriatic Sea. The scheme used is SOFA (System for Ocean Forecast and Analysis, DE MEY & BENKIRAN, 2002) and this is the first coastal application of this scheme. The CTD data were collected in 4 coastal areas (Emilia-Romagna coastal strip, the Gulf of Trieste, the Rovinj and Pelje ac-Vis-Drvenik coastal strips) while temperature profiles were acquired with XBT in the southern Adriatic Sea deep ocean areas. The analysis skill scores are examined in order to evaluate the assimilation performance. The results of the assimilation are first compared with independent analyses of satellite Sea Surface Temperature (SST) and it is found that assimilation of profiles improves the SST model estimate. Furthermore, the Root Mean Square (RMS) difference between model and temperature and salinity profiles before data insertion is analysed. The range of RMS temperature error is less than 1 0C for the entire area and decreases with time, indicating a positive impact of the assimilation. The RMS of salinity is less than 1 psu and it also shows a decreasing trend during the assimilation period.
The ADRICOSM Pilot Project: a coastal and river basin prediction system for the Adriatic Sea
Sergio CASTELLARI,Nadia PINARDI,Alessandro COLUCCELLI
Acta Adriatica , 2006,
Abstract: The ADRICOSM project was launched in October 2001, and ended in March 2005, with the main objective of demonstrating the feasibility of a near real time operational marine monitoring and forecasting system at the shelf and coastal scales, with connections to river basin runoff and coastal town sewer systems. The basic system consisted of an efficient network for the collection of marine data such as in situ temperature and salinity profiles and satellite sea surface temperature, a regional (AREG) and shelf scale modeling system, a data assimilation system and finally a coastal scale modeling system. Every week AREG releases 7 day marine forecasts at 5 km horizontal scales, which are used to nest other hydrodynamic models toward the coastal scale. Two shelf models (ASHELF-1 and ASHELF-2) at a 1.5 km horizontal scale were nested in AREG in order to simulate (and in the future to forecast) shelf scale oceanographic features. Another important aspect of ADRICOSM was the integration of the Cetina river (Croatia) and urban sewage monitoring/ modeling (Split, Croatia) systems with the shelf marine model. This integrated model system was used to simulate the dispersion of sewer discharges from the urban area in the coastal waters for water management performance studies. ADRICOSM is one of the first integrated land and marine waters operational oceanographic systems able to meet the urgent needs for reliable integrated coastal forecasts for the effective management of marine areas.
The Use of Ocean-Colour Data to Estimate Chl-a Trends in European Seas  [PDF]
Giovanni Coppini, Vladyslav Lyubarstev, Nadia Pinardi, Simone Colella, Rosalia Santoleri, Trine Christiansen
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.46087
Abstract:

Ocean-colour remote-sensing products have been used to estimate Chl-a trends in European seas with the aim to develop a new indicator based on ocean-colour data for the European Environment Agency (EEA). The new indicator, called CSI023(+), derived from satellite ocean-colour products from the MyOcean Marine Core Service (www.myocean.eu) has been defined and calculated. In our analysis, we have used 3 MyOcean satellite products: 2 global satellite products (SeaWiFS and a merged product) and one regional (adjusted to specific regional Mediterranean conditions) ocean-colour product. We have evaluated the differences among the 3 different products in estimating Chl-a trends. CSI023(+) complements the EEA CSI023 indicator for eutrophication based on chlorophyll-a (Chl-a) in-situ observations. Analysis has revealed the potential of ocean colour as a CSI023(+) indicator to detect large-scale, and in some cases, even local-scale, changes and decreasing trends of Chl-a were observed throughout the Black Sea, the Eastern Mediterranean, the southern part of the Western Mediterranean, the English Channel and the north part of the North Sea. Large areas with increasing trends were observed in the Bay of Biscay, in the North-East Atlantic regions of Ireland and the UK, in the northern part of the North Sea, in the Kattegat and in the Baltic. Specific analysis has been performed in the Mediterranean coastal areas using regional products to investigate local scale results. Validation of ocean-colour products has been carried out through comparison

The Adriatic basin forecasting system
Paolo ODDO,Nadia PINARDI,Marco ZAVATARELLI,Alessandro COLUCCELLI
Acta Adriatica , 2006,
Abstract: A regional ocean forecasting system has been implemented in the framework of the ADRIatic sea integrated COastal areaS and river basin Management system Pilot Project (ADRICOSM). The system is composed of a 5 km horizontal resolution model and an observing system collecting coastal and open ocean hydrological data. The numerical model is based on the Princeton Ocean Model using a SMOLARKIEWICZ iterative advection scheme, interactive air-sea flux computation, Po and other Adriatic rivers flow rates and is one-way nested to a general circulation model of the Mediterranean Sea. In this study the data from the observing system are used only for model validation. The results of the first operational year are shown and the model performance has been assessed based on root mean square (RMS) criteria.
HANNAH ARENDT: LA LóGICA DEL PENSAMIENTO IDEOLóGICO O LA RADICALIDAD DEL MAL
Pinardi,Sandra;
EPISTEME , 2007,
Abstract: in this article we examine one of the theses proposed by hannah arendt in her book: the origins of totalitarianism. hannah arendt asserts that xxth century totalitarianism can be distinguished from other forms of tyrannical governments, because its foundation and action are based on the logic of ideological thought; a particular kind of ?ideology?, privileging technical and mechanical movement, processes and systems, over meanings, therewith canceling every possible reflexive or free individual action. to understand this logic of ideological thought and its consequences, it is necessary to consider some phenomena analyzed by arendt in her text, such as, ?impermanence? and ?society of the one?.
IMPORTANT TREMATODES IN MAN IN INDONESIA
Pinardi Hadidjaja
Bulletin of Health Research , 2012,
Abstract: Trematode infections are considered to be a non public health problem in Indonesia, with the excep-tion of the two species namely Schistosoma japonicum and Fasciolopsis buski which are still assumed to be the most important trematodes of Indonesia. Other trematode infections reported occasionally were caused by: Echinostoma spp, Haplorchis yokogawai, Haplorchis taichui, Paralecithodendrium molenkampi, Phaneropsolus bonnei and Plachiorchis javensis. Schistosoma japonicum infection has been known to be endemic among the inhabitants of Lake Lindu since 1937. Surveys carried out since that time revealed prevalence rates which varied from 8-55%. Further studies proved that the species at Lindu were similar to the species found in Asia. Resurvey initiated in 1971 gave almost a similar prevalence rate followed by the discovery of the molluscan intermediate host namely Oncomelania hupensis lindoensis. In 1972 a new focus of schistosomiasis was discovered at Napu Valley. Other survey did not reveal any other endemic foci. The result of a biological study carried out since 1976 reconfirmed the diagnosis of the species. Clinical study showed that the significant signs and symptoms of schistosomiasis found among the Lindu inhabitants were : dermatitis, diarrhea, dysentry, abdominal pain, nausea and vomiting, loss of appetite, weakness, distention of the abdomen, melaena. hepatomegaly and splenomegaly. Control of schistosomiasis was initiated in 1981, using praziquantel for mass treatment. Twelve cycles of treatment at Lake Lindu area and 10 cycles at Napu Valley resulted in a reduction of overall prevalence rate from 15,80 % at Lindu area in 1981 to 1,14 % in 1987 whereas in Napu Valley the reduction was from 35,8 % in 1982 to 1,00 % in 1987. Fasciolopsis buski infection was first reported in 1982 from the Regency of Babirik, Hulu Sungai Utara in South Kalimantan Province. The following survey in that area in 1986 revealed a prevalence rate of 27,0 %. Clinical examination showed that some of the complaints were : diarrhea, poor appetite, mild abdominal colic or burning sensation, vomiting and fever. Physical examination revealed emaciation, anemia, distented abdomen, ascites, and jaundice. Another survey in four other adjacent villages showed prevalence rates that varied from 0,00% - 68,3%. The epidemiological survey carried out recendy did not reveal the intermediate hosts except only two metacercariae which could not be identified.
Peak-Shaped-Based Steganographic Technique for MP3 Audio  [PDF]
Raffaele Pinardi, Fabio Garzia, Roberto Cusani
Journal of Information Security (JIS) , 2013, DOI: 10.4236/jis.2013.41003
Abstract:

The aim of this work is the development of a steganographic technique for the MP3 audio format, which is based on the Peak Shaped Model algorithm used for JPEG images. The proposed method relies on the statistical properties of MP3 samples, which are compressed by a Modified Discrete Cosine Transform (MDCT). After the conversion of MP3, it’s possible to hide some secret information by replacing the least significant bit of the MDCT coefficients. Those coefficients are chosen according to the statistical relevance of each coefficient within the distribution. The performance analysis has been made by calculating three steganographic parameters: the Embedding Capacity, the Embedding Efficiency and the PSNR. It has been also simulated an attack with the Chi-Square test and the results have been used to plot the ROC curve, in order to calculate the error probability. Performances have been compared with performances of other existing techniques, showing interesting results.

The Adriatic Sea modelling system: a nested approach
M. Zavatarelli,N. Pinardi
Annales Geophysicae (ANGEO) , 2003,
Abstract: A modelling system for the Adriatic Sea has been built within the framework of the Mediterranean Forecasting System Pilot Project. The modelling system consists of a hierarchy of three numerical models (whole Mediterranean Sea, whole Adriatic Sea, Northern Adriatic Basin) coupled among each other by simple one-way, off-line nesting techniques, to downscale the larger scale flow field to highly resolved coastal scale fields. Numerical simulations have been carried out under climatological surface forcing. Simulations were aimed to assess the effectiveness of the nesting techniques and the skill of the system to reproduce known features of the Adriatic Sea circulation phenomenology (main circulation features, dense water formation,flow at the Otranto Strait and coastal circulation characteristics over the northern Adriatic shelf), in view of the pre-operational use of the modelling system. This paper describes the modelling system setup, and discusses the simulation results for the whole Adriatic Sea and its northern basin, comparing the simulations with the observed climatological circulation characteristics. Results obtained with the northern Adriatic model are also compared with the corresponding simulations obtained with the coarser resolution Adriatic model. Key words. Oceanography: general (continental shelf processes; numerical modelling) – Oceanography: physical (general circulation)
Advocacy and Policy Change in the Multilevel System of the European Union: A Case Study within Health Policy  [PDF]
Nadia Carboni
Open Journal of Political Science (OJPS) , 2012, DOI: 10.4236/ojps.2012.23005
Abstract: Health policy is basically Member States’ competence. However, the European Union has recently raised a number of key questions facing both (pharmaceutical) industries and public health interests. By applying the Advocacy Coalition Framework, the paper sheds light on policy change within the European multilevel system. The analysis is based on a case-study strategy. Two processes in the pharmaceutical policy are taken into account: the “Pharma Forum” and the “Pharma Package”. They both concern “information to patient”—a controversial policy issue at the crossroad of competing pressures.
