Censimento delle macroalghe marine bentoniche delle coste pugliesi

ItSulla base dei dati di letteratura viene presentato un catalogo delle macroalghe marine bentoniche delle coste pugliesi. La flora risulta costituita di 616 taxa a livello specifico e infraspecifico di cui 385 Rhodophyta (compresi 23 taxa inquirenda), 119 Phaeophyta (compresi 5 taxa inquirenda), 105 Chlorophyta (compresi 9 taxa inquirenda), 5 Incertae sedis, 2 Nomina nuda. Inoltre vengono elencati 13 taxa excludenda e 38 taxa identificati solo a livello generico. La flora delle coste adriatiche è risultata molto più ricca (569 specie) di quella delle coste ioniche (450 specie). Le specie comuni ai due mari sono 405, mentre quelle segnalate solo per le coste adriatiche sono 164 e solo 45 quelle esclusive delle coste ioniche. Da un punto di vista fitogeografico la flora mostra particolari affinità con flore di aree meridionali quali l'isola di Linosa, l'isola di Lampedusa e la Tunisia.EnOn the basis of literature data a check-list of the benthic marine macroalgae from Apulia is given. The list of taxa at specific and infraspecific level consists of 384 Rhodophyta (23 taxa inquirenda included), 119 Phaeophyta (5 taxa inquirenda included), 105 Chlorophyta (9 taxa inquirenda included), 5 Incertae sedis, 2 Nomina nuda. Thirteen taxa excludenda and 38 taxa identified at generic level only, are listed too. The flora of the Adriatic coast, with its 569 species, resulted richer than that of the Ionian coast consisting of 450 species. Four hundred and five species are shared by both seas, while 164 and 45 are exclusive of the Adriatic Sea and of the Ionian Sea, respectively. From a phytogeographic point of view, the Apulian flora shows affinities with floras of southern areas like Linosa Island, Lampedusa Island and Tunisia

Development and applications of two and three component particle image velocimetry techniques for simultaneous measurement in multi-phase flows and automative fuel sprays

The introduction of a new imaging approach for simultaneous multi-phase and multi-constituent velocity measurements is the main focus of this research. The proposed approach is based on the use of a single off-the-shelf colour camera which will enable simultaneous imaging of phases/constituents which are colourtagged using fluorescent droplets and multi-wavelength illumination. Highly efficient florescent tracers used to seed the constituents are presented and their visibility in full field imaging experiments is evaluated. A commonly found problem in experimental systems using laser illumination, known as flare, is discussed and the application of the developed fluorescent tracers for its reduction is presented. A strong focus of the imaging approach proposed is its flexibility and simplicity allowing its extension to stereoscopic imaging to obtain simultaneous multi-phase/constituent 3-component measurements with the addition of a second imaging camera. Proof of principle experiments with spatially separated and well mixed flows are presented for which successful phase discrimination is obtained and the uncertainty of the measurements is estimated. The imaging system developed is applied for simultaneous air and fuel velocimetry measurements in a Gasoline Direct Injection spray for which a more detailed understating of the interaction mechanisms is required to generate improved designs. The modified imaging system and experimental setup are presented and previously unavailable simultaneous air/fuel 2 and 3-component velocity fields are presented and analysed.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Prima segnalizione de "Ceramium cingulatum" Weber van Bosse ("Rhodophyta, Ceramiaceae") in Italia e osservazioni sul suo ciclo biologica in coltura

The presence of Ceramium cingulatum Weber van Bosse, up to now recorded in the Mediterranean Sea only from France and Spain, is firstly reponed from Italy. Since of this species only the tetrasporophytes are known, cultures by tetrasporas have been carried out in order to study its life history. Under experimental conditions, C. cingulatum shows an apomictic cycle.Se comenta la presencia en Italia de Ceramium angulatum Weber van Bosse, especie que solo había sido citada en el mar Mediterráneo para las costas francesas y españolas. Debido a que únicamente se conoce el tetrasporofito de la especie, se han realizado cultivos de tetrásporas a fin de estudiar su ciclo vital. En condiciones experimentales, C. angulatum desarrolla un ciclo apomíctico

Guida illustrata alle alghe del Golfo di Trieste

Questo libro contiene una chiave dicotomica per l'identificazione delle alghe marine piu' comuni dell'Alto Adriatico, basata su caratteri di facile osservazione e quindi relativamente accessibile per principianti. Le 113 schede illustrate, con la descrizione molrfologica e la distribuzione dei taxa, includono piu' della meta' dell'intera flora marina del Golfo di Trieste. L'introduzione illustra sinteticamente le principali caratteristiche ambientali del Golfo di Trieste e spiega i principali caratteri utilizzati nella chiave per il riconoscimento delle alghe. L'appendice comprende il glossario dei termini scientifici utilizzati nel testo. La guida \ue8 consigliata ai seawatcher che visitano l'Area Marina Protetta di Miramare dove sono state scattate parte delle immagini
