Structure and stability of rare-earth and transition-metal oxides
No full textThe structural parameters of rare-earth oxides lanthania (La2O3) and ytterbia (YbO), and of transition-metal oxides yttria (Y2O3) and lutetia (Lu2O3), candidate replacements of silica as gate insulators in nanometric Si electronics, are determined via ab initio calculations. The stability against formation of silica, silicides, and silicates for these oxides in contact with silicon is also investigated: we find stability against silica and silicide formation, but not against silicates
Il rapporto tra la fattispecie di reato di falsa perizia ex art. 373 c.p. e la nuova fattispecie di falsità in processo penale e depistaggio
No full textThe new crime of falsehood in the criminal trial and misdirection has been introduced in the Italian Legislation by the Law July 11th 2016, no. 133. The authors discuss about the applicability of the new offense even to the expert appointed by the court in the criminal trial, and if so, on what terms this crime is raised to that of false expert opinion and interpretation
Luci ed ombre delle polizze assicurative per responsabilità professionale medica con clausola claims made
No full textThe exponential increase in disputes within the context of professional responsibility of physicians has led to the introduction of new clauses to be included in insurance policies for civil liability, including the claims-made and loss occurrence clauses. Particularly, the use of both pure and mixed claims-made clauses is increasing among the Italian insurance providers. The peculiarity of such clauses lies in the period of cover, since the notice of a compensation claim must be received by the insurer during the coverage period. This paper aims to analyze the repercussions resulting from these new types of policies within our legal system, and, particularly, to highlight the views expressed in doctrine and case law precedents in the recent years
Malignant hyperthermia: A case report
No full textMalignant hyperthermia manifests clinically as a hypermetabolic crisis when a malignant hyperthermia-susceptible individual is exposed to a volatile anesthetic such as halothane, isoflurane, enflurane, sevoflurane, or desflurane or depolarizing muscular blockers such as succinylcholine. The condition shows autosomal dominant inheritance with reduced penetrance, and is mostly associated with mutations resulting in abnormal ryanodine receptor type 1 or, more rarely, dihydropyridine receptors. Exposure to triggering agents may lead to unregulated passage of calcium from the sarcoplasmic reticulum into the intracellular space, resulting in an acute malignant hyperthermia crisis. Mortality from malignant hyperthermia in the United States was 16.9% in 2001 and 6.5% in 2005, but it is characterized by high morbidity. Therapy is based on suspension of the triggering agent and administration of dantrolene. Diagnosis is possible by biopsy using in vitro contraction tests or DNA screening for malignant hyperthermia. The authors present a case of malignant hyperthermia during myocardial revascularization through off-pump coronary artery bypass graft
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
REPETITA: detection and discrimination of the periodicity of protein solenoid repeats by discrete Fourier transform
No full textMotivation: Proteins with solenoid repeats evolve more quickly than non-repetitive ones and their periodicity may be rapidly hidden at sequence level, while still evident in structure. In order to identify these repeats, we propose here a novel method based on a metric characterizing amino-acid properties (polarity, secondary structure, molecular volume, codon diversity, electric charge) using five previously derived numerical functions.
Results: The five spectra of the candidate sequences coding for structural repeats, obtained by Discrete Fourier Transform (DFT), show common features allowing determination of repeat periodicity with excellent results. Moreover it is possible to introduce a phase space parameterized by two quantities related to the Fourier spectra which allow for a clear distinction between a non-homologous set of globular proteins and proteins with solenoid repeats. The DFT method is shown to be competitive with other state of the art methods in the detection of solenoid structures, while improving its performance especially in the identification of periodicities, since it is able to recognize the actual repeat length in most cases. Moreover it highlights the relevance of local structural propensities in determining solenoid repeats
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Medico-legal and traumatological aspects of orbital fractures: A case report
No full textOrbital fractures account for 10-25% of all facial fractures. The etiology of such injuries can be traced to: acts of violence (36%), motor vehicle accidents (32%), falls (18%), sports injuries (11%), occupational accidents (3%) and gunshot wounds (2%). In 30% of cases, or-bital fractures are associated with intraocular complications, 11-15% of which are serious ophthalmic emergencies that may cause reduced visual acuity. In this paper, we report the case of a motorcyclist who was treated for complex facial fractures (orbital, sphenoid, ethmoid and zygomaticomaxillary complex fractures involving the mastoid air cells and nasal conchae as well as the septum, nasal fractures and fractures in the pterygoid plates). After an initial diagnostic assessment, the doctors determined that the most criti-cal damage was caused by the trauma inflicted to the left orbital walls. An open reduction was therefore carried out on this injury about a month later. The trauma had caused, on the one hand, a marked alteration of the patient's facial appearance, and on the other hand, at a functional level, the onset of diplopia. This article analyses the long-term ef-fects of orbital fractures on the patients' physical fitness, considering the specific experi-ence from the clinical case reported. © EUROMEDITERRANEAN BIOMEDICAL JOURNAL
