Principal Poincar\'e Pontryagin Function associated to some families of Morse real polynomials
2014
It is known that the Principal Poincar\'e Pontryagin Function is generically an Abelian integral. We give a sufficient condition on monodromy to ensure that it is an Abelian integral also in non generic cases. In non generic cases it is an iterated integral. Uribe [17, 18] gives in a special case a precise description of the Principal Poincar\'e Pontryagin Function, an iterated integral of length at most 2, involving logarithmic functions with only one ramification at a point at infinity. We extend this result to some non isodromic families of real Morse polynomials.
Automorphisms of hyperelliptic GAG-codes
2009
Abstract We determine the n –automorphism group of generalized algebraic-geometry codes associated with rational, elliptic and hyperelliptic function fields. Such group is, up to isomorphism, a subgroup of the automorphism group of the underlying function field.
Cloud-based eHealth video encoding system for real time thermographic streaming: Performance evaluation
2017
Recent studies about the use of cloud platforms indicate that more than three-fourths of healthcare institutions apply these technologies in their daily lives. However, in most cases the cloud is based on “Infrastructure as a Service”, instead of developing new applications using the benefits that can bring us this type of technology. For these reasons, this paper shows a private cloud-based system to provide a new application based on thermographic video streaming. In this case, the cloud architecture is divided into three zones. The first zone is where the patient is under medical supervision through body temperature analysis using a global thermal camera. The second zone is the cloud its…
The role of punishment in the works of Adam Smith
2009
The reformation of criminal justice is one of the great themes in Enlightenment culture and concerned its main exponents from Montesquieu to Beccaria, Filangieri, Bentham. One of the traits of greater modernity in the theories worked out by juridical Enlightenment is the resort to the utilitarianinspired economic analysis. Adam Smith doesn't back out of this scientific and civil commitment, but his doctrine appears significantly different though contemporary to juridical Enlightenment, and is also based on economic argumentations. In this work we will look through the main writings which contain the Smithian thought in search of those parts dealing with the theme of punishment and its socia…
Regulation of ISWI chromatin remodelling activity.
2013
The packaging of the eukaryotic genome into chromatin facilitates the storage of the genetic information within the nucleus, but prevents the access to the underlying DNA sequences. Structural changes in chromatin are mediated by several mechanisms. Among them, ATP-dependent remodelling complexes belonging to ISWI family provides one of the best examples that eukaryotic cells evolved to finely regulate these changes. ISWI-containing complexes use the energy derived from ATP hydrolysis to rearrange nucleosomes on chromatin in order to favour specific nuclear reactions. The combination of regulatory nuclear factors associated with the ATPase subunit as well as its modulation by specific histo…
Associations Among Psychologically Controlling Parenting, Autonomy, Relatedness, and Problem Behaviors During Emerging Adulthood.
2017
ABSTRACTThe present study aimed to investigate the relations among perceived parental psychological control (PPC), autonomy and relatedness, and negative outcomes during emerging adulthood in two cultural contexts: Italy and the USA. More specifically, we explored the mechanisms through which dependency-oriented PPC (DPPC) and achievement-oriented PPC (APPC) are associated with both internalizing and externalizing difficulties, focusing on the mediating role of autonomy and relatedness. Participants were 418 European-American and 359 Italian college students. Results indicated that the expressions of PPC with regard to dependency and achievement were related to emerging adults’ negative out…
Determinants of prescription opioid use: population‐based evidence from Finland
2019
BACKGROUND AND AIMS Previous studies have shown that prescription opioid use is more common in socio-economically disadvantaged communities in the United States. This study examined the area and individual-level determinants of prescription opioid use in Finland during the period 1995-2016. DESIGN Logistic regression analysis using nation-wide data on filled opioid-related prescriptions dispensed at Finnish pharmacies and covered by National Health Insurance. Opioid consumption was linked, using personal identification codes, to population-based data maintained by Statistics Finland, which records individual background and area-level characteristics. SETTING AND PARTICIPANTS Working-age pop…
Development and validation of a reliable method for studying the distribution pattern for opiates metabolites in brain
2012
Abstract Brain distribution pattern of “street” heroin metabolites (morphine and codeine) was investigated in two fatalities due to “acute narcotism”. A suitable sample pretreatment prior to solid-phase-extraction was developed to achieve a good recovery of the analytes and to eliminate the interfering species. After derivatization with MSTFA, samples were analyzed by GC/MS. Specificity, accuracy, precision and linearity of the method were evaluated; LOD and LOQ were, respectively, 10 ng/25 ng for morphine and 5 ng/10 ng for codeine. This method was applied to the analysis of six brain areas (hippocampus, frontal lobe, occipital lobe, nuclei, bulb and pons) coming from two cases of heroin-r…
Unexpected variation of the codeine/morphine ratio following fatal heroin overdose.
2014
Postmortem samples from 14 cases of suspected heroin overdose were subjected to a preliminary systematic toxicological analysis in order to highlight the presence of unknown exogenous compounds (e.g., drugs of abuse, alcohol) that may have played a role in the mechanism of death. This analysis unveiled histories of poly-drug use in seven of the cases under investigation. Moreover, the concentrations of morphine and codeine in the brain were also investigated, and the results were compared with the data obtained from the blood specimens. The concentration of morphine in blood ranged from 33 to 688 ng/mL, while the concentration of codeine ranged from 0 to 193 ng/mL. However, in the brain, th…
Postmortem distribution of dihydrocodeine and metabolites in a fatal case of dihydrocodeine intoxication.
1998
A report of a fatal dihydrocodeine ingestion under substitution therapy is given. Quantitation of dihydrocodeine, dihydromorphine, N-nordihydrocodeine, dihydrocodeine-6-, dihydromorphine-6- and dihydromorphine-3-glucuronide was performed simultaneously after solid-phase extraction prior to HPLC analysis, and the analytes were detected using their native fluorescence. Postmortem concentrations of blood samples from different sampling sites as well as from liver, kidney and cerebrum are reported. A hair sample was investigated to prove long-term use of the substitute drug. Site-to-site differences of the analytes from blood samples were very small. The partition behavior of the opioid glucuro…
