The performance of different Cu-based coins in artificial sweat was evaluated. The electrochemical behavior of the coins was
determined by potentiodynamic polarization curves, linear polarization resistance, and electrochemical impedance spectroscopy.
Regardless of the chemical composition of the Cu-based coins, they showed similar polarization cur...

... is worth noticing that the quaternary Cu-Zn-Al-Sn alloys exhibited the lowest corrosion rate. Table 3 shows the electrochemical parameters of the Cu-based coins determined from polarization curves in the region of ±250 mV with respect to corrosion potential. Importantly, all tested coins show a similar anodic-cathodic behavior, with possible significant variations at overpotentials above 0 volts. ...

Background: The surface roughness of restoration is important in predicting the length of time it might remain in the mouth. Conditions within the oral cavity can affect the surface roughness of a restoration. Nanohybrid composite is widely used in dentistry because it can be applied to restore anterior and posterior teeth. Athletes routinely consu...
Background
Meticulous identification and investigation of patients presenting with tuberculosis (TB) suggestive symptoms rarely happen in crowded outpatient departments (OPDs). Making health providers in OPDs diligently follow screening procedures may help increase TB case detection. From July 2010 to December 2013, two symptom based TB screening a...
In this paper we present a new record of a rare sweat bee species Lasioglossum anellum in Romania, at more than half of a century from its first mention. The specimen was collected from Stânca Ștefănești nature reserve and is among one of the northernmost records of this bee in Europe. We describe the collection site and provide an updated distribu...
