The aim was to identify the most reliable method, by evaluating the technical results obtained, as well as by making a supporting statistical analysis aimed at the definition of the agreement degree between the two methodologies. In detail, we individuated the nine most used wood-based panels by a kitchens producer and we performed two different types of analysis: the GA method and chamber method. As properly described in this paper, the chamber method has a higher reliability due to the more realistic environmental testing conditions; moreover, we have demonstrated a low correlation between the two methodologies.

We give a precise definition of the realization of a Turing-computable algorithm into a physical situation. This definition is not based, as usual, on an interpretation function of physical states, but on an implementation function from machine states to physical states (as suggested by Piccinini G, Computation in physical systems. The Stanford encyclopedia of philosophy. http://plato.stanford.edu/archives/fall2012/entries/computation-physicalsystems. Accessed 5 Dec 2013, 2012). We show that our definition avoids difficulties posed by Putnam’s theorem (Putnam H, Representation and reality. MIT Press, Cambridge, 1988) and Kripke’s objections (Stabler EP Jr, Kripke on functionalism and automata. Synthese 70(1):1–22, 1987; Scheutz M, What is not to implement a computation: a critical analysis of Chalmers’ notion of implementation. http://hrilab.tufts.edu/publications/scheutzcogsci12chalmers.pdf. Accessed 5 Dec 2013, 2001). Using our notion of representation, we analyse Gandy machines, intended in a physical sense, as a case study and show an inaccuracy in Gandy’s analysis with respect to the locality notion. This shows the epistemological relevance of our realization concept. We also discuss Gandy machines in quantum context. In fact, it is well known that in quantum mechanics, locality is seriously questioned, therefore it is worthwhile to analyse briefly, whether quantum machines are Gandy machines.

Between the end of June and the beginning of August of 2017, three eggs were laid in a group of 29 lesser flamingos kept under human care. Two eggs and one chick were abandoned by the parents, and three chicks were hand-reared. This report describes diet composition, dietary intake, feeding protocols, and growth index, from the first day to 60 days after hatching, for three lesser flamingo chicks.

Ultrasonography plays an important role in modern-day cetacean preventative medicine because it is a non-invasive technique, it is safe for both patient and operator, and it can be performed routinely using trained responses that enable medical procedures. Reproductive success is an important aspect of dolphin population health, as it is an indicator of the future trajectory of the population. The aim of this study is to provide additional relevant data on feto-maternal ultrasonographic monitoring in bottlenose dolphin (Tursiops truncatus) species, for both the clinicians and for in situ population studies. From 2009 to 2019, serial ultrasonographic exams of 11 healthy bottlenose dolphin females kept under human care were evaluated over the course of 16 pregnancies. A total of 192 ultrasound exams were in...

Protein electrophoresis, combined with the determination of total protein concentration, is the standard method for the determination of serum albumin concentration. An alternative method is the bromocresol green (BCG) dye-binding method. The BCG method for the measurement of albumin concentration in reptiles may lead to inaccurate results for serum albumin concentration. The aim of this study was to compare the serum albumin values of Hermann’s tortoises (Testudo hermanni) obtained by protein electrophoresis and the BCG method and to test the reliability of the BCG method for the measurement of albumin concentration in this species of tortoise. Between May and June 2012, serum samples from 32 Hermann’s tortoises, 22 healthy and 10 diseased, were analyzed. Serum albumin concentrations were measured by protein electrophoresis and by the BCG method. The results of the two methods were compared using Passing–Bablok regression and Bland–Altman plots. Albumin concentration measured by BCG was moderately correlated with the corresponding protein electrophoretic values in all tortoises (rs = 0.545, P = 0.001) and in healthy tortoises analyzed separately (rs = 0.491, P = 0.020). In diseased tortoises, correlation between the testing methods was not significant (rs = 0.602, P = 0.066). The albumin concentrations measured using the two methods differed significantly in all tortoises (P = 0.0005; “effect size” = 0.50), in healthy tortoises (P = 0.0262; “effect size” = 0.61), and in diseased tortoises (P = 0.0059, “effect size” = 0.62). In the Bland–Altman plots, a systematic error was found between the two methods in diseased tortoises. The albumin concentrations measured by BCG were significantly higher than those obtained with electrophoresis, especially in diseased Hermann’s tortoises. The analysis of albumin in the BCG method gave falsely elevated concentrations. Therefore, for health assessment in Hermann’s tortoises, albumin should be measured by protein electrophoresis.
