2D dynamical arrest transition in a mixed nanoparticle-phospholipid layer studied in real and momentum spaces
2015
AbstractWe investigate the interfacial dynamics of a 2D self-organized mixed layer made of silica nanoparticles interacting with phospholipid (DPPC) monolayers at the air/water interface. This system has biological relevance, allowing investigation of toxicological effects of nanoparticles on model membranes and lung surfactants. It might also provide bio-inspired technological solutions, exploiting the self-organization of DPPC to produce a non-trivial 2D structuration of nanoparticles. The characterization of interfacial dynamics yields information on the effects of NPs on the mechanical properties, important to improve performances of systems such as colloidosomes, foams, creams. For thi…
SENSORY EVALUATION AND SUITABILITY FOR FRESH-CUT PRODUCE OF WHITE PEACH [PRUNUS PERSICA (L.) BATSCH] 'SETTEMBRINA DI BIVONA'
2015
âSettembrina di Bivonaâ peaches were cut into slices to assess their suitability as fresh-cut produce. Untreated (control) and treated with calcium lactate fresh cut slices were closed in plastic boxes for 24 hours (T1) or five days of storage (T2) at 5°C, and then placed at 20°C to assess consumersâ liking. Soluble solids content, titratable acidity, firmness and pH were measured. A sample of n = 750 consumers was selected taking into consideration three variables: age (from 25 to 55 years old), professional status (employed) and aptitude to buy fresh-cut fruit for personal use. A systematic sampling was used, with a detection point based in a properly selected supermarket during t…
A Dominant Global Translation Strategy in Thai Translated Novels : The Translations of Religious Markers in Dan Brown’s Thriller Novels
2020
When translation is considered as an integral part of larger social systems (Even-Zohar 1990), the ways in which translations are produced to serve readers’ specificity could be affected. This paper examines whether there is a preference for a specific global translation strategy due to a readership that is specialized in terms of education level. Adopting Venuti’s (1995/2008) division of global translation strategies into exoticizing and domesticating translation, it examines the frequency of local translation strategies, which are part of a global translation strategy, used in translating English-Thai religious markers in Dan Brown’s Angels and Demons, The Da Vinci Code, The Lost Symbol, …
Coexistence of active Brownian disks: van der Waals theory and analytical results
2020
At thermal equilibrium, intensive quantities like temperature and pressure have to be uniform throughout the system, restricting inhomogeneous systems composed of different phases. The paradigmatic example is the coexistence of vapor and liquid, a state that can also be observed for active Brownian particles steadily driven away from equilibrium. Recently, a strategy has been proposed that allows to predict phase equilibria of active particles [Solon et al., Phys. Rev. E 97, 020602(R) (2018)2470-004510.1103/PhysRevE.97.020602]. Here we elaborate on this strategy and formulate it in the framework of a van der Waals theory for active disks. For a given equation of state, we derive the effecti…
Lévy flights in confining potentials.
2009
We analyze confining mechanisms for L\'{e}vy flights. When they evolve in suitable external potentials their variance may exist and show signatures of a superdiffusive transport. Two classes of stochastic jump - type processes are considered: those driven by Langevin equation with L\'{e}vy noise and those, named by us topological L\'{e}vy processes (occurring in systems with topological complexity like folded polymers or complex networks and generically in inhomogeneous media), whose Langevin representation is unknown and possibly nonexistent. Our major finding is that both above classes of processes stay in affinity and may share common stationary (eventually asymptotic) probability densit…
INTERSPECIFIC VARIATION IN TOTAL PHENOLIC CONTENT IN TEMPERATE BROWN ALGAE
2015
The aim of this study was to focus on interspecific variation of total phenolic contents (TPC) in temperate brown algae also considering their relationship with environmental conditions. In particular, we compared the TPC of four species characterized by different thallus morphology, growth cycle and bathymetric level: Cystoseira amentacea (C. Agardh) Bory, Cystoseira compressa (Esper) Gerloff & Nizamuddin, Dictyopteris polypodioides (A.P. De Candolle) J.V. Lamouroux and Padina pavonica (Linnaeus) Thivy, collected in summer 2011 from the north-western coast of Sicily.
Epizootiology of protozoans in farmed salmonids at northern latitudes
1997
Abstract Protozoan ectoparasites were examined in a northern salmonid fish farm over a 10-year period, June 1984–May 1994, by the same researcher, with similar catching and sampling procedures throughout. Husbandry procedures remained constant during the study, e.g., fingerlings were kept in steel tanks and yearlings in both steel tanks and earth ponds. Ichthyobodo necator, Chilodonella hexasticha and Ichthyophthirius multifilurs infections were treated with formalin, salt and malachite green-formalin baths, respectively, whenever any parasites were found. Altogether 10 790 randomly sampled salmon (Salmo solar), sea trout (S. trutta m. trutta) and brown trout (S. trutta m. lacustris) were s…
Nocturnal drift of mayfly nymphs as a post-contact antipredator mechanism
2000
SUMMARY 1. The predominantly nocturnal constrained drift of stream invertebrates is commonly regarded as a behaviour that avoids encounters with visually foraging fish in the water column. The alternative explanation, that drift peaks are caused by bottom-feeding, nocturnal predators, has rarely been tested. 2. We examined these hypotheses by collecting invertebrate drift in five streams in northern Finland: one with brown trout (Salmo trutta, a drift-feeding fish), one with alpine bullhead (Cottus poecilopus, a benthic fish), one with both species, and two fishless streams. 3. Drift by Baetis mayflies was aperiodic or slightly diurnal in both fishless streams on all sampling occasions. In …
Finnish salmon resistant to Gyrodactylus salaris: a long-term study at fish farms.
1996
Abstract The occurrence of Gyrodactylus salaris on Baltic salmon ( Salmo salar ), sea trout ( S. trutta m. trutta ) and brown trout ( S. trutta m. lacustris ) was examined from 1984 to 1993 at 4 fish farms (A, B, C and D) that produce smolts for stocking in northern Finland. No G. salaris was found on the sea or brown trout, but it did occur on salmon for 6–7 years at farms B, C and D, the prevalences of infection being 9.5%, 17.7% and 8.8% for salmon yearlings and smolts during that time, respectively, but less than 1.2% for fingerlings at farms B and C. Only brood stock salmon were infected at farm A in 4 years. The abundances of G. salaris increased during the second winter of each year …
Fundamentos de la obra cinematográfica de Clarence Brown : inicios y consolidación estilística en el contexto del cine clásico norteamericano entre l…
2012
Esta tesis tiene por objeto el estudio del legado artístico del director y productor cinematográfico Clarence Brown (1890-1987), quien desarrolló su actividad desde 1915 hasta 1953, primero en Fort Lee, New Jersey, y posteriormente en Hollywood. Su corpus fílmico, por lo tanto, comprende parte del cine “silente” y “sonoro” norteamericano. Aunque Brown se formó junto a uno de los grandes pictorialistas de la era “silente”, el realizador de origen francés Maurice Tourneur, y la calidad y originalidad de su obra han sido reivindicadas por reputados historiadores como Kevin Brownlow y William K. Everson, en la actualidad continúa siendo un cineasta olvidado, injustamente relegado por la Histori…
