The Role of Cartilage-perichondrium Tympanoplasty in the Treatment of Tympanic Membrane Retractions: Systematic Review of the Literature.
2022
Abstract Introduction Tympanic retraction is a condition characterized by the displacement of the tympanic membrane toward the structures of the middle ear. Clinically, tympanic retractions can lead to hearing loss, ear discharge and/or ear pain. In most of the cases, however, tympanic retractions are asymptomatic and are found accidentally during an ear, nose, and throat (ENT) examination. This condition has created numerous debates regarding the optimal choice of treatment, especially in the asymptomatic forms. The main controversy is regarding the relationship between retraction and the development of cholesteatoma, which would justify a surgical intervention performed for preventive pur…
Partial trisomy 9p and partial monosomy 6q resulting from paternal reciprocal translocation 6;9: Overlapping manifestations of characteristic phenoty…
2003
We report on a female infant with partial trisomy 9p (p13.3→pter) and monosomy 6q (q26-qter) resulting from a paternal balanced reciprocal traslocation t(6;9)(q26;p13.3). Both trisomy 9p and monosomy 6q are recognized phenotypes with characteristic patterns of anomalies. This patient is the first reported with a partial deletion 6q and a partial duplication 9p resulting in an overlapping phenotype including intrauterine growth retardation (IUGR), craniofacial and skeletal abnormalities, congenital heart defect, hypotonia and developmental delay. We present the clinical follow-up of this patient from birth to age 4 years: the phenotypic manifestations of trisomy 9p syndrome are mildly expres…
L'effettiva applicazione del principio del contraddittorio nel procedimento amministrativo tributario tra svolte, ripensamenti e attese
2015
The right to a proper hearing in the administrative tax proceedings represents an essential element of the full exercise of the taxpayer’s right of the defense (art. 24 of the Italian Constitution), as well as of the implementation of the principle of good performance and impartiality of tax administration (art. 97 of the Italian Constitution), as recognized by the constitutional Court and the Supreme Court case law, in the light of European and international law. Taxpayer’s right to a proper hearing, as part of the rights of the defense, is a general principle of Community law which applies where the tax authorities are minded to adopt a measure which will adversely affect an individual. L…
INFLUENCE OF UNCERTAINTIES ON ROTATING FLEXIBLE SHAFT SUSPENDED BY 4-AXIS RADIAL ACTIVE MAGNETIC BEARINGS µ-SYNTHESIS AND LOOP-SHAPING-DESIGN
2012
This paper shows a comparison about dynamic behavior of a rotating shaft when it is suspended by 4-axis radial active magnetic bearing system. The active magnetic suspension is obtained by two different controllers which realize the robust stability and robust performance. The control systems used are µ-synthesis and loop shaping design procedure. Each of these controllers is characterized by fourinput and four output signals and the introduction of uncertainties on displacement gain and current gain is justified by the simple fact that during the time the component which constitutes these gains can be subjected to torn and worn which can lead the entire system to instability phenomena. The…
Condition Assessment and Analysis of Bearing of Doubly Fed Wind Turbines Using Machine Learning Technique
2023
Condition monitoring of wind turbines is progressively increasing to maintain the continuity of clean energy supply to power grids. This issue is of great importance since it prevents wind turbines from failing and overheating, as most wind turbines with doubly fed induction generators (DFIG) are overheated due to faults in generator bearings. Bearing fault detection has become a main topic targeting the optimum operation, unscheduled downtime, and maintenance cost of turbine generators. Wind turbines are equipped with condition monitoring devices. However, effective and reliable fault detection still faces significant difficulties. As the majority of health monitoring techniques are primar…
On the biomechanical function of scaffolds for engineering load-bearing soft tissues
2009
Replacement or regeneration of load-bearing soft tissues has long been the impetus for the development of bioactive materials. While maturing, current efforts continue to be confounded by our lack of understanding of the intricate multi-scale hierarchical arrangements and interactions typically found in native tissues. The current state of the art in biomaterial processing enables a degree of controllable microstructure that can be used for the development of model systems to deduce fundamental biological implications of matrix morphologies on cell function. Furthermore, the development of computational frameworks which allow for the simulation of experimentally derived observations represe…
Universal newborn hearing screening in the Italian Region of Sicily in 2018
2021
We have clarified the role of Universal Neonatal Hearing Screening (UNHS) for both early diagnosis and rapid treatment in order to improve the prognosis of the deaf child and reduce patient management costs. Although in Sicily UNHS has been progressively implemented, there is scarce data in the literature on this matter. Therefore, the main objective was to collect in the year 2018 the following data: number of newborns screened for hearing loss, number of infants "referred" to transiently evoked otoacoustic emissions (TEOAE), number of infants with pathologic auditory brainstem response (ABR) and number of infants affected by permanent hearing loss.UNHS monitoring was conducted through the…
Estudio comparativo de dos metodologías aplicadas para la comprensión de la música contemporánea en la educación secundaria obligatoria
2016
In this paper we try to discover which methodology is more appropriate for the comprehension of the contemporary music in the Secondary Education. For that purpose by a quasi-experiment, mixed, qualitative and quantitative, the preserved results through the application of two different methodologies have been compared: a traditional one base on the masterly class and another based in different kinds of audition. The obtained results after the didactical application on the quantitative level weren´t significant, however, on the qualitative level we could also observe that the pupils who subjected to that methodology had more advantageous results regarding to the comprehension of the contempo…
Hearing-impaired pupils in mainstream education in Finland: teachers’ experiences of inclusion and support
2017
Today, in Finland, the majority of hearing-impaired pupils attend regular schools. This is in line with inclusive policy. This study aims to investigate do these pupils receive support from teacher ...
Sharp estimates and saturation phenomena for a nonlocal eigenvalue problem
2011
Abstract We determine the shape which minimizes, among domains with given measure, the first eigenvalue of a nonlocal operator consisting of a perturbation of the standard Dirichlet Laplacian by an integral of the unknown function. We show that this problem displays a saturation behaviour in that the corresponding value of the minimal eigenvalue increases with the weight affecting the average up to a (finite) critical value of this weight, and then remains constant. This critical point corresponds to a transition between optimal shapes, from one ball as in the Faber–Krahn inequality to two equal balls.
