Methodology of Chewing’s sound acquisition by different detectors for dry food in terms of crispness and crunchiness
No full textThis paper presents an acoustic detection methodology, providing an overview of Sound Profile Analysis (SPA) and objective data for food sensory analysis. The main goal of present work is improving the sensorial evaluation of crispness and crunchiness on dry food by mastication’s sound. This is aimed to the definition of a quality index for “crispy” and “crunchy” perceptual parameters, which are the main texture attributes affecting acceptability of food regarding auditory sensations. The innovative approach consists of using acoustical transducers to measure the objective acoustic parameters on chewing’s food sound.
Three different types of transducers were tested (cardioid condenser microphones at a distance, binaural microphones inserted at the entrance of the ear ducts of subject & piezo-electric transducers placed on cheeks of subject) to cover the main principles of vibro-acoustic propagation: air transmission and bone conduction. The binaural microphones resulted in better signals.
The recorded waveforms were processed with existing software for performing spectrum analysis and computing standard acoustical parameters such as levels in dB, reverberation time in seconds and other “objective” acoustical parameters. The ones chosen for SPA are those who revealed better statistical properties and good correlation with laboratory measurements of texture and hardness data

Surgical treatment of a chronic thoracoabdominal dissection with false lumen thrombosis and true lumen compression determining multivisceral ischemia
No full textIntroduction The treatment of a chronic type B aortic dissection can be challenging and need a precise and multidisciplinary planning. Materials and Results A 62-year-old man presented to our hospital with acute aortic thrombosis on chronic thoracoabdominal dissection with bowel and kidney ischemia. He was submitted to urgent open surgical treatment with replacement of thoracoabdominal aorta and reimplantation of celiac trunk, superior mesenteric artery and right renal artery. During the intervention the visceral perfusion was provided with a modified Gott shunt; while the lower limb perfusion was provided by an existing right axillo-femoral and femoro-femoral bypass. The patient had a favorable course and did not report any complications. Conclusion The ideal management strategy of complex post-dissection conditions has to be tailored on the single patient's features to provide the maximal efficacy and safety. If the endovascular treatment is not viable, open surgery represents a valid option
Microdebrider cavitation and transcervical removal of parapharyngeal schwannomas approaching the skull base.
No full textRemoval of parapharyngeal space (PPS) schwannomas approaching the skull base through a purely transcervical approach requires adequate visualization of the surgical field to obtain complete resection with minimal sequelae. This is a retrospective series of four patients undergoing transcervical removal of sympathetic chain PPS schwannomas abutting the skull base by an intracapsular microdebrider tumor cavitation. Radiologic data, complications, functional outcomes, and follow-up status were considered. MRI was suggestive of PPS schwannoma in all cases, and correctly predicted the nerve of origin in three out of four cases. All patients developed postoperative Claude Bernard-Horner and first-bite syndromes. One patient also presented temporary neuropraxia of the IX cranial nerve, and another of the IX and X cranial nerves. Microdebrider cavitation of sympathetic chain PPS schwannoma abutting the skull base proved to be a reliable technique allowing good visualization of adjacent neural and vascular structures through a purely transcervical approach, while maintaining a low complication rate
Pneumosinus dilatans of the maxillary sinus: a case report and review of the literature.
No full textMyocardial revascularization with both internal thoracic arteries 25 years after delayed repair for aortic coarctation
No full textAortic coarctation has been reported to cause alterations in the internal thoracic arteries that make these vessels unsuitable to be used as grafts for myocardial revascularization, especially if coarctation repair was performed in adulthood. This is the first reported bilateral internal thoracic grafting for myocardial revascularization in a patient who had undergone aortic coarctation repair 25 years earlie
Scattering Matrix of a Reciprocal and Lossless, Three-Port Power Divider
No full textThe analytical expression of the scattering matrix of a lossless, reciprocal three-port junction is derived using three arbitrary real angles. This derivation extends a previously proposed method that was limited to cases with a plane of symmetry. The derived formulas are validated analytically and confirmed through both full-wave analysis of a stripline divider and experimental measurements of a strongly asymmetrical and a quasi-symmetrical waveguide divider
