Local thermal equilibrium and ideal gas Stephani universes
2005
The Stephani universes that can be interpreted as an ideal gas evolving in local thermal equilibrium are determined. Five classes of thermodynamic schemes are admissible, which give rise to five classes of regular models and three classes of singular models. No Stephani universes exist representing an exact solution to a classical ideal gas (one for which the internal energy is proportional to the temperature). But some Stephani universes may approximate a classical ideal gas at first order in the temperature: all of them are obtained. Finally, some features about the physical behavior of the models are pointed out.
Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.
2019
l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazione dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordinazione conseguente alla riduzione del cam…
Copper, iron, and zinc contents in human milk during the first three months of lactation: A longitudinal study
2000
The aim of the study has been to analyze the evolution of copper, iron, and zinc contents in human milk, from colostrum to the third postpartum month, following a longitudinal design, under specific conditions of sample collection and to apply an analytical procedure previously optimized to reduce any variation outside physiological lactation. The copper, iron, and zinc concentrations in 144 milk samples from 39 healthy puerpera women, were analyzed in five stages by flame atomic absorption spectrometry, following a standardized protocol. Copper presented a gradual decrease from 0.38 mg/L to 0.19 mg/L by the 90th day; the particular analysis from colostrum to transitional milk manifested th…
The Relationship Between Tooth Size Discrepancy and Archform Classification in Orthodontic Patients
2015
Background: To determine the relationship between clinically significant tooth size discrepancies (TSD) and archform classification in orthodontic patients. Material and Methods: Two hundred and forty consecutive sets of pre-treatment orthodontic study models were scanned and landmarked. All models had permanent teeth erupted from first molar to first molar in both arches. Sixty sets of images were classified into two groups of 30 according to the presence (group 1) or absence (group 2) of a clinically significant overall or anterior TSD (>2 SD from Bolton’s original means). Mean upper and lower archforms were created for each group using a fourth degree polynomial curve. Upper and lower ar…
Risk Factors Associated with Carious Lesions in Permanent First Molars in Children: A Seven-Year Retrospective Cohort Study
2020
The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M…
A first return examination of vector valued integrals.
2009
We prove that for each Bochner integrable function f there exists a trajectory yielding the Bochner integral of f, and that on infinite dimensional Banach spaces there exist Pettis integrable functions f such that no trajectory yields the Pettis integral of f.
Live, Laugh and Love to Learn Turning Learning from Traditional to Transformational
2015
In recent years, educators and policy makers have been focusing on student achievement and well-being. After the great Pisa -success and glory, Finnish researchers have risen up discussion about future skills, school activity and motivation – fields where Finnish students haven’t indicated so well. Quickly changing 21st century challenges teachers to see life outside the school and recognize not only the core subjects but also the key skills needed outside there. When transferring from traditional to transformational education, one has to imagine new ways to think about teaching and learning. The research project, introduced in this article, focuses on transformational pedagogic and the que…
Cisternostomy for Traumatic Brain Injury: A New Era Begins
2016
Traumatic brain injury (TBI) is a major cause of death and disability especially in the young generations. In the United States TBI affects about 1.7 million people annually [1] and this number is higher in the developing countries. It is well known that TBI is associated to a primary and secondary brain injury. The first is without solution and depends on the impact. In surviving patients, what plays a critical role is the subsequent secondary injury since, without effective treatments, complex cascades will promote additional brain damage.
From Bench to Bedside—The Bad Berka Experience With First-in-Human Studies
2019
Precision oncology is being driven by rapid advances in novel diagnostics and therapeutic interventions, with treatments targeted to the needs of individual patients on the basis of genetic, biomarker, phenotypic, or psychosocial characteristics that distinguish a given patient from other patients with similar clinical presentations. Inherent in the theranostics paradigm is the assumption that diagnostic test results can precisely determine whether an individual is likely to benefit from a specific treatment. As part and integral in the current era of precision oncology, theranostics in the context of nuclear medicine aims to identify the appropriate molecular targets in neoplasms (diagnost…
Fuzzified Tree Search in Real Domain Games
2011
Fuzzified game tree search algorithm is based on the idea that the exact game tree evaluation is not required to find the best move. Therefore, pruning techniques may be applied earlier resulting in faster search and greater performance. Applied to an abstract domain, it outperforms the existing ones such as Alpha-Beta, PVS, Negascout, NegaC*, SSS*/ Dual* and MTD(f). In this paper we present experimental results in real domain games, where the proposed algorithm demonstrated 10 percent performance increase over the existing algorithms.
