INTRODUCTION. Dental injury occurres in 0.06 - 0.13 % of general anesthesia procedures re- quiring endotracheal intubation, and it is still a reason of complaint against anesthetists. Maxil- lary central incisors are the most commonly teeth injured.1 In our center claims related to teeth damage after intubation ended with a total reimbursement of 13.000 Euros (2014-2015) and 5 patients (2014 to June 2016) were admitted for cares in Prosthodontics Implant dentistry dept. Dental School - Turin. BUCX et al.2 used a strain gauge based sensor between handle and blade of the laryngoscope to measure forces applied on the maxillary incisors to show that during routine laryngoscopy great forces are exerted on the maxillary incisor teeth with no differences based on the operator experience. OBJECTIVES.The aim of this study is to measure of the forces applied on teeth using a direct laryngoscope or a McGRATH® videolaringoscope. Many authors described how lower force on soft tissue could be applied using a VLS (GlideScope) instead of a standard laryngoscope (P=0.05).3, but no studies have ever been performed involving the use of a force sensor directly applied on teeth. The aim of our study is to measure the forces applied on teeth after the application of a cus- tomized bite (2 mm dental bite) applied on the manikin. Anesthesiologists and anesthesia residents from “Città della Salute e della Scienza”,Turin will be asked to perform 3 intubations using the standard intubation system, and other 3 using McGRATH® videolaringoscope in order to test the intubation forces exerted

Urban air pollution, climate and its impact on asthma morbidity

AbstractObjectiveTo study the mechanism of formation of air quality and to determine the impact of the studied factors on asthma morbidity in Vladivostok.MethodsThe evaluation of air pollution in Vladivostok was done using long-term (2008–2012) monitoring data (temperature, humidity, atmospheric pressure, wind speed, etc.). The levels of suspended particulate matter, nitrogen and sulfur dioxide, carbon monoxide, ammonia, formaldehyde (mg/m3) in six stationary observation posts were assessed. We studied the aerosol suspensions of solid particles, which were collected during snowfall from precipitation (snow) and air in 14 districts with different levels of anthropogenic impact. Melted snow was analyzed on laser granulometry. The impact of air pollution on the distribution of asthma morbidity was evaluated in various age groups by data of federal statistical observation obtained from 8 adults and 7 children municipal clinics in Vladivostok (2008–2012).ResultsThe content of suspended particulate components of pollution remained more stable, due to the features of atmospheric circulation, rugged terrain and residential development. The nano- and micro-sized particles (0–50 μm), which can absorb highly toxic metals, prevail in dust aerosols. These respirable fractions of particles, even in small doses, can contribute to the increase in asthma morbidity in the city.ConclusionsWe determined that asthma morbidity depends from general air pollution (in the range of 18.3%). It was detected that the highest age-specific dependence is associated with the content of particulate matter, carbon monoxide and nitrogen dioxide in air

Surface nanophotonics with Bloch waves on dielectric multilayers

Planar mutilayers sustaining either TE or TM polarized Bloch Surface Waves (BSWs) offer new opportunities for management of light at the nanoscale. We will discuss how BSWs can be exploited in guiding and confining light on nanometric relieves, enhancing fluorescence emission and providing additional features for plasmonic nano-antennas

Silicon-carbon-oxynitrides grown by plasma-enhanced chemical vapor deposition technique

In this paper we report some preliminary results about the growth at low temperature (493 K) of hydrogenated silicon–carbon–oxygen– nitrogen amorphous thin-film alloys (a-SiCxOyNz:H) by means of capacitively-coupled radio-frequency (13.56 MHz) plasma-enhanced chemical vapor deposition using a mixtures of silane (SiH4), propane (C3H8), nitrous oxide (N2O) and ammonia (NH3) precursor gases. Thin films of a- SiCxOyNz:H were grown at different deposition conditions, obtaining growth speeds varying from 0.22 to 0.44 nm/s. The films were characterized by means of Fourier transform infra-red spectroscopy in order to investigate the internal bonding structure, by UV–VIS transmittance spectroscopy to check the optical properties and by mechanical profilometry to measure the film thickness and estimate the growth rate. The comparison of structural and optical properties of samples grown with and without NH3 presence in the gas mixture showed that the ammonia addition allows a better control of nitrogen incorporation in the film structure, while increasing film transparency and reducing the growth rate

Stability and quantum efficiency of a novel type of a-Si:H/a-SiC:H based UV detector

UV detectors based on a-Si:H/a-SiC:H were deposited by plasma enhanced chemical vapor deposition and characterized in terms of their photoelectrical properties. A quantum efficiency of 90%, corresponding to 0.28 A/W, at 365 nm was measured for devices having p-layer and i-layer thickness less than 10 nm. A good uniformity (15%) was achieved on area of 5×5 cm. A linear dependence of the photocurrent as a function of impinging photon flux, corresponding to a constant responsivity, was found. Aging experiments were performed by UV irradiation both on devices and on thin films inserted in the detectors with the aim of investigating the possible correlations
