Una spiaggia policentrica : progetto di un sistema di centralita' urbane per la riqualificazione di Misano Adriatico

Il miglioramento dell’ambiente urbano e, in particolare, della qualità di vita dei cittadini, così come lo scriteriato consumo di territorio in favore della barbara cementificazione delle aree non edificate, sono diventate questioni di particolare rilievo nello scenario globale finalizzato al raggiungimento di un nuovo modello di sviluppo delle città. Gli abitanti dei centri urbani, oggi, sono costretti ad affrontare il sovraffollamento e i problemi ad esso connessi: il traffico, la congestione, l’inquinamento e gli effetti che questi fattori generano alla società. L’area oggetto di questa tesi, luogo a forte vocazione turistica, presenta questo tipo di problematiche soprattutto in corrispondenza della stagione estiva mentre, per il resto dell’anno, si trova ad affrontare il problema opposto di riduzione delle attività e dello spopolamento causate dalla stagionalità. L’espansione edilizia, avvenuta con estrema rapidità e durante un periodo caratterizzato da un forte sviluppo economico , non ha seguito gli indirizzi di un Piano che avrebbe se non altro evitato sprechi di territorio e una struttura così caotica. Tradizionalmente l’idea di densità è sempre stata considerata in maniera negativa rispetto alla questione urbana, in quanto simbolo di un uso intensivo e indiscriminato del territorio e causa della scarsa qualità di vita che caratterizza molte città. In realtà il concetto di densità può assumere un significato diverso: legato all’efficienza, alla qualità e alla sostenibilità. Densificare, infatti, secondo opportune linee guida e in relazione agli standard di qualità, significa sfruttare al meglio le risorse esistenti all’interno delle città, utilizzando il territorio senza sprechi e ricucendo le fratture in grado di generare situazioni di degrado ambientale. Un complesso e minuzioso processo di “densificazione” è in grado di apportare molti benefici al cittadino e alla comunità, come la trasformazione degli spazi inutilizzati o dismessi, la riduzione delle distanze e della mobilità veicolare, la limitazione dell’impatto energetico sull’ambiente e, non ultima, la promozione di una nuova immagine urbana connessa a nuove funzionalità e strutture. Densificare è però condizione necessaria ma non sufficiente per il miglioramento dell’ambiente urbano, infatti il termine “densità” non specifica nulla sul risultato qualitativo e quantitativo che si intende ottenere. “Creazione di un ambiente più propizio alla vita ed intenzionalità estetica sono i caratteri stabili dell’architettura; questi aspetti emergono da ogni ricerca positiva ed illuminano la città come creazione umana” . È in questo senso che deve essere letta la “densificazione” proposta da questa tesi per la riqualificazione di Misano Adriatico. Occorrerà riqualificare soprattutto quelle aree marginali del tutto prive dei requisiti urbani al fine di integrarle maggiormente al resto della città. A essa dovrà essere collegata una nuova visione di quelle che saranno le infrastrutture legate alla mobilità ed i servizi necessari alla vita della comunità. Essi non dovranno più essere visti come elementi di semplice collegamento o episodi isolati distribuiti a caso nel territorio, ma dovranno recuperare quell’importanza strategica che li portavano ad essere l’elemento catalizzatore e la struttura portante dell’espansione urbana. La riqualificazione della città sviluppata in questa tesi segue “la strategia dei luoghi complementari” teorizzata da O.M. Ungers secondo cui: “la città dei -luoghi complementari- è composta dal numero più grande possibile di aree diverse, nelle quali viene sviluppato un aspetto urbano particolare tenendo conto del tutto. In un certo senso è un sistema della -città nella città-. Ogni parte ha le sue proprie caratteristiche, senza però essere perfezionata e conclusa. […] Si cerca la molteplicità, la diversità, non l’unitarietà. La contraddizione, la conflittualità sono parte del sistema e rimangono insolute” . Il fine ultimo di questa tesi è quindi quello di proporre un’idea di città del nostro tempo, un prodotto complesso, non identificabile con un unico luogo ma con un insieme di luoghi che si sovrappongono e si integrano in maniera complementare mantenendo le peculiarità intrinseche del territorio a cui appartengono

Effect of nursery ground variability on condition of age 0+ year Merluccius hubbsi

This study examined the southern or Patagonian (41°–55° S) stock of Argentine hake Merluccius hubbsi, the more abundant of the two stocks on the Argentinean continental shelf. Pre-recruits (age 0+ year individuals) of this stock settle and grow in the San Jorge Gulf (45°–47° S, 65° 30′ W), a complex habitat with large spatial variability in environmental features. Relative condition factor, hepatosomatic index, lipid content and fatty-acid composition of muscle and liver, and diet information were combined with physical and biological data to evaluate: how nutritional status of age 0+ year hake varies spatially within the nursery ground; whether changes in condition are related to environmental factors and feeding; whether the indices are interchangeable metrics of condition. Both morphometric and biochemical indices showed dissimilar spatial trends; enhanced liver-based condition coincided with low salinity nutrient rich waters, higher chlorophyll-a values and abundances of Euphausia spp., the preferred prey at most stations, suggesting a bottom-up effect on age 0+ year hake condition. Diminished condition at stations where Thermisto gaudichaudii was the main prey could derive from lower prey quality in terms of energy density and essential fatty acids content. Coastal waters of the gulf would be essential habitats for M. hubbsi pre-recruits. Future monitoring of condition with liver-based indices is encouraged in the gulf, where interannual increasing trends of satellite-derived chlorophyll-a values have been observed, which could have implications for recruitment of the species.Fil: Temperoni, Brenda.

Appendicularians and marine snow in situ vertical distribution in Argentinean Patagonia

Detailed in situ vertical and temporal distribution of appendicularians, marine snow, fecal pellets, nano- and microplankton were recorded simultaneously with environmental data in the San Jorge Gulf, Argentinean Patagonia (45°-47°S). Data were taken at a fixed station over 36 h in February 2014 with an autonomous Video Plankton Recorder and a FlowCAM®. The water column was thermally stratified with a pycnocline at ~ 40 m. Appendicularians dominated in the upper 65 m with a condensed pattern above the pycnocline at high chlorophyll a concentrations, matching the subsurface chlorophyll maximum layer at ~ 20 m. Our results suggest the absence of vertical migration of appendicularians. Marine snow, strongly correlated with appendicularians, showed high concentrations above the pycnocline, whereas fecal pellets from krill were distributed throughout the water column. Discarded houses of appendicularians or their mucus fragments were the main components of marine snow aggregates, with phytoplankton, detritus and krill pellets also contributing. Nanoplankton dominated over microplankton, with vertical distribution patterns that might depend on local grazing pressure and advective processes. Our study, the first one in the region using underwater imagery, emphasizes the leading contribution of appendicularians to marine snow aggregates in the San Jorge Gulf and their potential implications in the bentho-pelagic coupling.Fil: Giménez, Eloísa Mariana.

A water-based sequential preparatory approach vs. conventional aquatic training in stroke patients: a randomized controlled trial with a 1-month follow-up

Background: Many studies hypothesize that people who have suffered stroke could benefit from water-based exercises to improve their strength and ability to perform the activities of daily living. Objective: The study aim was to compare the effects of a water-based sequential preparatory approach (SPA) and conventional aquatic therapy in improving motor functions and quality of life in patients with chronic stroke. Methods: Thirty-three chronic stroke outpatients diagnosed with hemiplegia were recruited and randomly assigned to the experimental or control group. Subjects in the experimental group underwent a trial water-based SPA balance training, and patients in the control group were given traditional water balance training. Both groups of participants underwent 45 min of therapy twice a week for 4 weeks. All patients were evaluated before treatment (T0), after 4 weeks of training (T1), and 4 weeks after the end of training (T2) using the Berg balance scale (BBS), the modified Barthel index (MBI), the Tinetti balance and gait scale (TBG), the Stroke Specific Quality Of Life Scale (SS-QOL), and the modified Ashworth scale (MAS). Results: After the training, statistically significant differences (p < 0.05) were found between the groups in their score averages on the BBS (p = 0.01) and the SS-QOL scale (p = 0.03). Furthermore, the SPAg showed a significantly greater percentage of improvement on the BBS (p = 0.02) and the SS-QOL (p = 0.03). Both groups obtained a significantly improved MAS score (p < 0.01). Conclusion: Results indicate that water training based on an SPA is more effective than traditional aquatic training for balance rehabilitation of chronic poststroke patients

Evaluating the role of endogenous and exogenous features on larval hake nutritional condition

Evaluating the nutritional condition of fish larvae is imperative to establish the importance of starvation, understanding the causes of larval mortality and determining favorable zones for growth and survival within nursery areas. We assessed the nutritional condition of Merluccius hubbsi larvae employing RNA/DNA index (sRD) and its derived index of growth performance (Gpf). Larvae (N = 395) were collected during the reproductive peak in 2010 and 2011. Principal Component Analysis and Generalized Linear Models were used to study the relationship between larval condition and endogenous factors (size, weight, growth rate, trophic incidence, and carbon content per stomach) and exogenous variables (temperature, chlorophyll concentration, potential prey availability, ctenophore biomass, and hake larvae density). The year of sampling was also considered as a variable. The significant variables in the model selection were size, temperature, the density of hake larvae, and year. The larval size was positively related to the condition while larval density and temperature showed a negative relationship with the sRD index. The year was also a significant variable, with higher larval sRD values in 2010. The negative relationship between sRD and larval density suggests the existence of mechanisms of density-dependence operating upon larval condition. On the other hand, the lower temperatures occurred in stratified waters (with greater availability of food) a fact that might explain the negative relationship between sRD and temperature. The fitting of the models suggests that other explanatory variables might be considered to improve the understanding of the nutritional condition index nature.Fil: Diaz, Marina Vera.

Seasonal and spatial variability in condition of age-0+ Argentine hake Merluccius hubbsi Marini, 1933, in the San Jorge Gulf (Argentina): A bottom-up perspective

In the north Patagonian region of the Argentinean Continental Shelf, the San Jorge Gulf (SJG; 45°‐47°S, 65°30ʹ‐67°30ʹW) is the main nursery ground of age‐0+ Argentine hake Merluccius hubbsi Marini, 1933, one of the most important fishery resources in Argentina. The gulf exhibits strong seasonal and spatial fluctuations in environmental features, which might affect survival of age‐0+ individuals and recruitment to the adult population. Our main goal was to evaluate the seasonal and spatial dynamics of their nutritional status within the SJG in winter 2016, spring 2016 and summer 2017. Condition indices (relative condition factor Kn, hepatosomatic index HSI and liver lipid content %L) and diet information (feeding incidence and relative importance of prey) were combined with physical (temperature and salinity) and biological (satellite chlorophyll‐a concentration; chl‐a) data. Age‐0+ condition indices and prey intake showed significant seasonal variations, with minimum values in winter, intermediate in summer and maximum in spring, strongly coupled to the mean chl‐a concentration in each season. Herbivorous euphausiids Euphausia spp. were the preferred prey along the study period. A bottom‐up effect on condition of age‐0+ hake is suggested, manifested as lower condition values in winter, the less productive season. Spatially, better conditioned individuals matched sectors of the gulf where chl‐a concentrations were higher, coupled to the presence of frontal systems. Monitoring age‐0+ hake nutritional status is relevant in the current global change scenario, which might modify phytoplankton biomass and composition and, consequently, the herbivorous zooplankton abundances.Fil: Temperoni, Brenda.
