Measurement of Mechanical Properties of Cantilever Shaped Materials
2008
Microcantilevers were first introduced as imaging probes in Atomic Force Microscopy (AFM) due to their extremely high sensitivity in measuring surface forces. The versatility of these probes, however, allows the sensing and measurement of a host of mechanical properties of various materials. Sensor parameters such as resonance frequency, quality factor, amplitude of vibration and bending due to a differential stress can all be simultaneously determined for a cantilever. When measuring the mechanical properties of materials, identifying and discerning the most influential parameters responsible for the observed changes in the cantilever response are important. We will, therefore, discuss the…
Observation of topological gravity-capillary waves in a water wave crystal
2019
The discovery of topological phases of matter, initially driven by theoretical advances in quantum condensed matter physics, has been recently extended to classical wave systems, reaching out to a wealth of novel potential applications in signal manipulation and energy concentration. Despite the fact that many realistic wave media (metals at optical frequencies, polymers at ultrasonic frequencies) are inherently dispersive, topological wave transport in photonic and phononic crystals has so far been limited to ideal situations and proof-of-concept experiments involving dispersionless media. Here, we report the first experimental demonstration of topological edge states in a classical water …
Capitale sociale pubblico e capitale sociale privato nel Sud
2010
Se intendiamo per capitale sociale pubblico il senso civico, per capitale sociale privato dobbiamo intendere la rete di relazioni sociali dell'individuo. Le regioni meridionali hanno meno capitale sociale inteso come bene pubblico. Ma anche famiglia e amicizia che sarebbero i porti franchi della socialità meridionale, mostrano nel tempo segni di deperimento.
Il valore del capitale sociale. Una rassegna critica della letteratura
2007
Scopo di questo saggio è mostrare, attraverso un esame critico della letteratura scientifica di punta sul tema, la varietà degli usi del concetto di capitale sociale. Se ne discutono le definizioni, si individuano gli aspetti e le componenti, i benefici ma anche le conseguenze negative. L’esame del concetto non può che concludere mostrandone la marcata ambiguità. Intanto in letteratura si possono rinvenire due definizioni distinte del concetto che difficilmente si conciliano. Una definizione considera il capitale sociale come una proprietà del sistema sociale, l’altra come una proprietà individuale. Anche gli studi empirici si dividono fra quelli che trattano il concetto al livello aggregat…
CAPITALE SOCIALE E SENSO CIVICO NEL MEZZOGIORNO
2008
I saggi che compongono questo libro muovono dall’ambizione di riuscire a vedere il Sud al di là delle spiegazioni sommarie e con spirito scevro da moralismi. Il luogo comune da cui guardarsi è quello per il quale i mali del Sud sono conseguenze di tare ataviche che pertengono alla persistenza di una mentalità chiusa e diffidente. Una mentalità refrattaria, per una sorta di antica e invincibile “cocciutaggine”, alle norme di cooperazione e lealtà astratta che si richiedono in una società complessa; una mentalità incline, per tanto, all’opportunismo. Qui l’autore prova a offrire chiavi descrittive e interpretative diverse. Non l’omertà, non l’arretratezza culturale, non la religiosità tradizi…
Implantation of the modified endocapsular bending ring in pediatric cataract surgery using a viscoadaptive viscoelastic agent.
1999
Cataract surgery and intraocular lens (IOL) implantation in pediatric eyes remain controversial. Using a viscoadaptive viscoelastic agent, we implanted a modified capsular bending ring (CBR) as well as an acrylic IOL with a sharp-optic-edge design in the capsular bag. All operated eyes demonstrated a low postoperative inflammatory reaction and a clinically well-centered IOL. The band-shaped, sharp-edged CBR facilitates the creation of a sharp, discontinuous bend in the equatorial capsule, which prevents anterior and posterior capsule opacification. Combining the viscoadaptive viscoelastic agent and the CBR enhances the safety of primary and secondary posterior chamber IOL implantation in pe…
Mid-infrared supercontinuum generation in chalcogenide and telluride fibers for sensor devices
2019
This thesis reports on the progress made during my PhD concerning supercontinuum generation and its application in two types of materials: chalcogenide and tellurite glasses. Concerning the chalcogenide axis, two new arsenic-free compositions are developed: Ge20Se60Te20 and Ge20Se70Te10. Thermal and optical properties of these two glasses are studied and two types of fibers are manufactured: a step-index fiber and a suspended core fiber. The generation of supercontinuum in these two fibres, pumped by an optical parametric amplifier, gives competitive results compared to the current state of the art of supercontinuum generation in chalcogenide fibres. Supercontinuums widening between 2 and 1…
Spatio-temporal dynamics of oscillatory network activity in the neonatal mouse cerebral cortex
2007
We used a 60-channel microelectrode array to study in thick (600-1000 microm) somatosensory cortical slices from postnatal day (P)0-P3 mice the spatio-temporal properties of early network oscillations. We recorded local non-propagating as well as large-scale propagating spontaneous oscillatory activity. Both types of activity patterns could never be observed in neocortical slices of conventional thickness (400 microm). Local non-propagating spontaneous oscillations with an average peak frequency of 15.6 Hz, duration of 1.7 s and maximal amplitude of 66.8 microV were highly synchronized in a network of approximately 200 microm in diameter. Spontaneous oscillations of lower frequency (10.4 Hz…
Agalsidase alpha and hearing in Fabry disease: data from the Fabry Outcome Survey.
2006
Fabry disease is an X-linked lysosomal storage disorder characterized by multi-organ dysfunction, including hearing loss - mainly sensorineural. The recent introduction of enzyme replacement therapy (ERT) has resulted in improvements in renal and cardiac function, pain and quality of life. One study has also suggested small improvements in high-frequency hearing. In this paper, we study the effect of ERT on hearing in patients in the Europe-wide database - the Fabry Outcome Survey (FOS). Twenty-six patients in FOS had pure-tone audiometry performed up to 6 months before starting ERT with agalsidase alpha and after a median of 12 months of treatment. We assessed changes in hearing thresholds…
La première rencontre du corps malade en contexte de soins infirmiers : la relation de soin : une expérience ultime, du sensible au social
2016
Our study focuses on nursing care with a first approach based on human body and emotions through the teaching context in the sensitive hospital environment. The nursing student is a central point of our research as he lives a unique sensitive and interpersonal experience within his own body in a social setting imbued with symbolism. He perceives health care community through his five senses which inform and direct him, but also may destabilize him. We decided to base our study on the information and communication sciences thanks to a sensitive, sensorial and symbolic problematisation and through a multidisciplinary conceptualization based on different theoretical approaches, symbolic intera…
