Treatment of columnaris disease of rainbow trout: low pH and salt as possible tools?
2005
The impact of salt and low pH on columnaris disease of fish was studied. Survival of Flavobacterium columnare after exposure to either 4% NaCl (pH 7.2) or pH 5.0, pH 4.86 or pH 4.6 for 15 min or 1 h was studied in vitro. All conditions significantly reduced the numbers of viable bacterial cells. The effects of salt (4 and 2%) and acidic baths (pH 4.6) were studied in 2 experiments in vivo with rainbow trout Oncorhynchus mykiss infected with F. columnare. Both salt and acidic baths failed to prevent fish mortality; the overall mortality reached 100% in all groups. However, according to survival analysis, the mortality rate was lower in fish treated with 4% salt baths compared to a control gr…
Flavonoids in sbtribe Centaureinae (Cass.) Dumort (tribe Carduae, Asteraceae): distibution and 13C spectral data
2012
Asteraceae Bercht. & J. Presl is one of the biggest and most economically important plant families. The taxonomy and phylogeny of Asteraceae is rather complex and according to the latest and most reliable taxonomic classification of Panero & Funk, based on the analysis of nine chloroplast regions, the family is divided into 12 subfamilies and 35 tribes. One of the largest tribes of Asteraceae is Cardueae Cass. with four subtribes (Carlininae, Echinopinae, Carduinae and Centaureinae) and more than 2500 species. Susanna & Garcia-Jacas have organized the genera of Centaureinae (about 800 species) into seven informal groups, which recent molecular studies have confirmed: 1. Basal genera; 2. Vol…
STUDIO DEL COMPORTAMENTO DINAMICO DI UN MODELLO HALF CAR E CONFRONTO FRA AMMORTIZZAZIONE PASSIVA E SEMIATTIVA A FLUIDO MAGNETO-REOLOGICO
2010
Questo lavoro inizia con la progettazione di massima del pistone di un ammortizzatore a fluido magnetoreologico, effettuata con l’ausilio di Solid Works e del software di simulazione magnetica FEMM. Le dimensioni preliminari sono state assegnate facendo uso delle relazioni teoriche, mentre il software FEMM ha confermato il risultato. Sono state poi ricavate le equazioni della dinamica di un modello half car, sia in forma di sistema di equazioni differenziali che in forma di spazio di stato. Tramite l’interfaccia SimuLink di MatLab, è eseguito un confronto fra i risultati ottenuti dal sistema in condizioni di funzionamento passivo con quelli in funzionamento semi-attivo. Scelta la geometria …

Perioperative and anesthetic deaths: toxicological and medico legal aspects
2019
Abstract Background Anesthesia has become safer during decades, though there is still a preventable mortality; the complexity of medical and surgical interventions, increasingly older and sicker patients, has created a host of new hazards in anesthesiology. In this paper, some of these perioperative (PO) fatal adverse events are investigated in terms of health responsibility. Selective literature research in several data bases, concerning perioperative and anesthetic deaths and medical responsibility, was performed. Main text A generally accepted definition of the anesthesia and perioperatory-related death still remains one of the major concerns in forensic pathology, and the terms “operati…
Preventable fatal injury during rally race: a multidisciplinary approach
2020
Abstract Introduction The motor vehicle crash (MVC) constitutes an important challenge for forensic pathology in order to identify the manner and cause of death. Our study focuses on a fatal accident during a rally race corresponding to MVC sub-category. Materials and method Postmortem computed tomography (PMCT) was performed before the conventional autopsy. Autoptic and PMCT data were compared. Data collection allowed analyzing biomechanical dynamics of the incident and post-traumatic injuries through qualitative-statistics and solicitation quantitative indices. Results Photo and circumstantial evidence analysis showed a wrong installation of double shoulder belt system of head and neck su…
Impacto de la modalidad de diálisis sobre la morbimortalidad del paciente trasplantado tras el fracaso del injerto renal
2018
1. Introducción: El trasplante renal es el tratamiento de elección de la enfermedad renal crónica terminal mejorando la calidad de vida y la supervivencia del paciente en comparación con las otras alternativas de tratamiento sustitutivo renal. Gracias a los avances en las técnicas quirúrgicas, la inmunosupresión y el manejo global del paciente trasplantado la supervivencia del injerto a corto-medio plazo ha mejorado pero no así la supervivencia a largo plazo, por lo que sigue habiendo un alto porcentaje de pacientes cada año que vuelven a diálisis. Se desconoce en la actualidad cual es la mejor técnica de diálisis para esos pacientes. Por un lado, la libertad que les ha otorgado el trasplan…
Una suggestione archilochea ne La Città Morta?

This note proposes the hypothesis that in La città morta, Act II, sc. I, d’Annunzio used a fragment of Archilochus, sent to us by Plutarch and Athenaeus.
On the exhaustive generation of k-convex polyominoes
2017
The degree of convexity of a convex polyomino P is the smallest integer k such that any two cells of P can be joined by a monotone path inside P with at most k changes of direction. In this paper we present a simple algorithm for computing the degree of convexity of a convex polyomino and we show how it can be used to design an algorithm that generates, given an integer k, all k-convex polyominoes of area n in constant amortized time, using space O(n). Furthermore, by applying few changes, we are able to generate all convex polyominoes whose degree of convexity is exactly k.
Post-mortem enamel surface texture alteration during taphonomic processes—do experimental approaches reflect natural phenomena?
2022
Experimental approaches are often used to better understand the mechanisms behindand consequences of post-mortem alteration on proxies for diet reconstruction.Dental microwear texture analysis (DMTA) is such a dietary proxy, using dental wearfeatures in extant and extinct taxa to reconstruct feeding behaviour and mechanicalfood properties. In fossil specimens especially, DMTA can be biased by post-mortemalteration caused by mechanical or chemical alteration of the enamel surface. Herewe performed three different dental surface alteration experiments to assess the effectof common taphonomic processes by simplifying them: (1) tumbling in sedimentsuspension to simulate fluvial transport, (2) s…
