In this work, the effect of erosion on corrosion behavior of coal tar epoxy coating was evaluated using electrochemical impedance spectroscopy (EIS) measurements. The surface morphology of the coating was examined by scanning electron microscope (SEM) after 10, 20, 30, 45 and 60 min of erosion process at an impact angle of 90º. After 10 min of erosion process, the Nyquist plots showed just a si...

the aims of this study were (a) to establish the occurrence, duration and intensity of behavioral estrus symptoms, and (b) to determine the relationship between behavioral estrus symptoms with the total estrogen profiles in cycling murrah buffaloes (n=10) subjected to doublesynch protocol (0 pgf2α, 2 gnrh, 9 pgf2α and 11 gnrh). after both gnrh injections, estrus and its behavioral signs were de...

Microelectrode technics were used to study the effects of procainamide (PA) on electrophysiologic properties of canine Purkinje fibers (PF) perfused in an extracorporeal circuit with arterial blood of donor dogs. Donor electrocardiogram (ECG) and blood pressure (BP) and electrophysiologic properties of the isolated PF were simultaneously monitored. PA, 25 mg/kg, was administered as a single int...

Background The palatal approach of anterior superior alveolar (P-ASA) using WAND injection was reported to effectively provide a profound bilateral maxillary anesthesia of the soft tissue of anterior one-third of the palate and facial gingivae extending from canine to canine which lasted for more than an hour thus making it ideal for scaling root planing and minor periodontal procedures in the ...

Ropivacaine 0.5%, 0.75% and 1.0% was investigated in an open study of extradural anaesthesia in three groups of 15 patients undergoing urological or orthopaedic surgery. Following a test dose of 3 ml of 1.0% lignocaine with 1:200,000 adrenaline, ropivacaine 20 ml was given in incremental doses over 4 min via a lumbar extradural catheter. The onset time for analgesia was short in all groups: T12...

The active region, AR0554, was observed with NIS/CDS on board SoHO to examine the extent and range of oscillations from a range of features. Among all the NIS spectral lines analysed, significant oscillations were found in Si xii 520 Å, Mg x 625 Å, O v 629 Å, and He i 522 Å. The periods of the strongest oscillations in these lines were ≈ 10–20 min. After the dominant 10–20 min oscillations were...

OBJECTIVE This study examined the occurrence and duration of sedentary bouts and explored the cross-sectional association with health indicators in children applying various operational definitions of sedentary bouts. METHODS Accelerometer data of 647 children (10-13 years old) were collected in five European countries. We analyzed sedentary time (<100 cpm) accumulated in bouts of at least 5,...
