Oggetto della comunicazione è una riflessione sul progetto urbano nella città di Tunisi e nel Mediterraneo. Sono state fatte delle riflessioni sui progetti urbani di Fernand Pouillon, Hassan Fathy, Jaques Marmey, Faruk Ben Miled, Vittorio Gregotti, Pasquale Culotta ed altri architetti, realizzati nelle città del Mediterraneo.

Invasion Ability and Disease Dynamics of Environmentally Growing Opportunistic Pathogens under Outside-Host Competition

2014

Most theories of the evolution of virulence concentrate on obligatory host-pathogen relationship. Yet, many pathogens replicate in the environment outside-host where they compete with non-pathogenic forms. Thus, replication and competition in the outside-host environment may have profound influence on the evolution of virulence and disease dynamics. These environmentally growing opportunistic pathogens are also a logical step towards obligatory pathogenicity. Efficient treatment methods against these diseases, such as columnaris disease in fishes, are lacking because of their opportunist nature. We present a novel epidemiological model in which replication and competition in the outside-hos…

A link between ectoparasite infection and susceptibility to bacterial disease in rainbow trout

2006

Rainbow trout, Oncorhynchus mykiss, were infected concomitantly with Argulus coregoni and Flavobacterium columnare and their survival was compared with that of fish infected with either the parasite or the bacterium alone. The mortality of fish challenged with A. coregoni was negligible while infection with F. columnare alone led to significantly lower survival. However, compared with single infections, the mortality was significantly higher and the onset of disease condition was earlier among fish, which were concomitantly infected by A. coregoni and F. columnare. This data presents, for the first time, experimental support for the hypothesis that an ectoparasite infection increases suscep…

Diuron environmental levels effects on marine nematodes: Assessment of ecological indices, taxonomic diversity, and functional traits

2021

Abstract Coastal marine systems are the most sensitive zones to emerging pollutants. The present study aims to investigate the effect of Diuron on the meiofaunal assemblages, collected from the Bizerte channel (Tunisia). Microcosm experiments were set up using four increasing Diuron concentrations [D1 (10 ng g−1 dry weight (DW)), D2 (50 ng g−1 DW), D3 (250 ng g−1 DW) and (1250 ng g−1 DW)] compared to non-contaminated sediments (controls) and all plots were incubated for 30 days. Our results show that Diuron-supplemented sediments provoked the significant decrease of meiofaunal abundance as well as a change in nematodes' diversity and structure composition. All univariate indices, as well as…

Factors Influencing Accounting Outsourcing Practices among SMEs in Pakistan Context: Transaction Cost Economics (TCE) and Resource-Based Views (RBV) …

2014

Published version of an article from the journal:International Journal of Business and Management. Also available from the publisher:http://dx.doi.org/10.5539/ijbm.v9n7p19 The present study was conducted to identify factors that affect Pakistani manufacturing SMEs decisions to outsource management accounting practices in terms of transaction cost economics (TCE) and resource-based view (RBV). A survey of 302 SMEs was carried out using convenience sampling, a personal interview owners/managers/CFOs located in 9 major cities of Pakistan. Our multiple regression analysis revealed that the frequency of non-routine tasks, asset specificity, opportunism, trust in accountant and competition has a …

Serum pancreatic enzymes in human immunodeficiency virus-infected children - A collaborative study of the Italian Society of Pediatric Gastroenterolo…

1998

Numerous studies have shown pancreatic disease in adult human immunodeficiency virus (HIV)-infected patients, but there are very few reports on pediatric patients. Our aim was to determine the prevalence of increased serum pancreatic enzyme levels and their relationship to clinical manifestations of acute pancreatitis in HIV-infected children.Forty-seven consecutive, symptomatic HIV-infected children (24 male; median age, 7.3 years; range, 1-17 years) and 45 sex- and age-matched controls without gastroenterologic disease were enrolled. In all subjects serum total amylase, pancreatic amylase, and lipase were assayed with commercial kits. The following were recorded: disease progression (CDC …

Organic matter quantity and quality, metals availability and foraminiferal assemblages as environmental proxy applied to the Bizerte Lagoon (Tunisia)

2016

International audience; This study analyzes the benthic trophic state of Bizerte Lagoon (Tunisia) based on the total organic matter and the bioavailability of biopolymeric carbon including proteins (PTN), carbohydrates (CHO), lipids (LIP), chlorophyll a, as well as bacteria counts. The overall simultaneously extracted metals (SEM), and acid volatile sulfides (AVS) as well as the SEM/AVS ratio indicative of the toxicity of the sediments also were analyzed aiming to study their impact in the dimension, composition and structure of both dead and living benthic foraminiferal assemblages.In the studied sites TOC content is relatively high and the PTN/CHO values indicate that they can be consider…

Les commissions coloniales rattachées au Comité des Travaux historiques et scientifiques

2000

The colonial Commissions connected to the Comité des travaux historiques et scientifiques. In the late nineteenth century, the Comité des travaux historiques et scientifiques became a bigger and bigger research organization, always closely linked to the successive political governments. With each new French conquest, a commission of parisian scientists and local correspondents was created and attached to it, as in 1864, the scientific commission for Mexico, in 1884, the commission for Tunisia, in 1908, the archeological commission for Indochina. The example studied here is that of the commssion for Tunisia, which coordonated researches in archeology and epigraphy in North Africa, thanks to …

L'attaccamento ai luoghi come modello interpretativo delle relazioni dell'uomo con la cultura. Una ricerca su un campione di ragazzi tunisini della c…

2014

L'attaccamento al luogo è un essenziale bisogno umano in grado di nutrire il senso dell'identità di individui e collettività, a prescindere dai cambiamenti della società. Intento principale in questo lavoro di tesi è quello dell'integrazione, legato al fenomeno dell' intercultura. Il lavoro di tesi è riferito nello specifico nella città di Mazara del Vallo, centro nevralgico di incontro di culture. Ho scelto di indagare la percezione del luogo da parte della popolazione immigrata, coinvolgendo in particolare gli adolescenti che costituiscono la cosiddetta "seconda generazione", e confrontandone le opinioni con quelle espresse dai coetanei autoctoni. L'aspetto più propriamente statistico rig…
