In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

Nano hexagonal wurtzite ZnO has been prepared on zeoliteA by the sono-chemical method. The zeoliteA was mixed into Zinc gel, after stirring for two days, the mixture was irradiated 30 min by ultrasonic probe. The filtrated composite gel was calcinated at 500°C for 3h in furnace. The produced composite was characterized using X-ray diffraction, FT-IR spectroscopy and field emission scanning elec...

Disruptions in local chromatin structure often indicate features of biological interest such as regulatory regions. We find that sonication of cross-linked chromatin, when combined with a size-selection step and massively parallel short-read sequencing, can be used as a method (Sono-Seq) to map locations of high chromatin accessibility in promoter regions. Sono-Seq sites frequently correspond t...

The possibility of in vivo carcass quality prediction in breeding process using ultrasound method was studied. attention was paid to marbling and intramuscular fat content prediction and the effect of breed and age on prediction accuracy was evaluated. The study was carried out on 75 bulls (38 Slovak Simmental, 14 Beef Polled Simmental and 23 charolais). The ultrasound machine aLoka SSD-500 wit...

Objective: To infer the prevalence and variables predictive of isolated nocturnal hypoxemia and obstructive sleep apnea (OSA) in patients with COPD and mild hypoxemia. Methods: This was a cross-sectional study involving clinically stable COPD outpatients with mild hypoxemia (oxygen saturation = 90-94%) at a clinical center specializing in respiratory diseases, located in the city of Goiânia, ...

Binaural masking level difference is the behavioral threshold difference between a diotic condition (SoNo) and a dichotic condition with a 180 degrees interaural phase delay of either the signal (SpiNo) or the masker (SoNpi). Threshold disparity is partially related to coincidence-detecting units in the medial superior olive that are sensitive to low-frequency binaural stimuli with interaural p...

The current paper reports on a sonochemical synthesis method for manufacturing nanostructured (typical grain size of 50 nm) SrTi0.6Fe0.4O2.8 (Sono-STFO40) powder. This powder is characterized using X ray-diffraction (XRD), Mössbauer spectroscopy and Scanning Electron Microscopy (SEM), and results are compared with commercially available SrTi0.4Fe0.6O2.8 (STFO60) powder. In order to manufacture ...

AIM To analyze the interventions aimed at the practice of sleep hygiene, as well as their applicability and effectiveness in the clinical scenario, so that they may be used by pediatricians and family physicians for parental advice. SOURCE OF DATA A search of the PubMed database was performed using the following descriptors: sleep hygiene OR sleep education AND children or school-aged. In the...

Review Question/Objective L'obiettivo è di presentare le migliori evidenze disponibili sull'uso della contenzione fisica per prevenire l'autorimozione dei presidi nei pazienti adulti critici Background La ragione principale per l'uso della contenzione fisica in terapia intensiva è quello di proteggere i pazienti dall' auto-rimozione dei dispositivi terapeutici. Anche se la contenzione fisica è ...
