Natural Evolution of Infantile Regurgitation Versus the Efficacy of Thickened Formula

Abstract: Background:Regurgitation is frequent in infants. We evaluated changes in regurgitation among patient groups fed standard formula, standard formula subsequently thickened with cereal, or formula manufactured with bean gum as a thickening agent.Patients and Methods:A prospective, blinded, rand

Green electroluminescence from an n-ZnO: Er/p-Si heterostructured light-emitting diode

Abstract: Erbium-doped ZnO (ZnO:Er) thin films with various doping concentrations were deposited on p-Si substrates by ultrasonic spray pyrolysis (USP) The n-ZnO:Er/p-Si heterojunctions were further employed to fabricate light-emitting diodes (LEDs) The devices showed diode-like rectifying current–voltage characteristics with a low reverse breakdown voltage, attributed to the avalanche breakdown A distinct green electroluminescence peaking at 537 nm and 558 nm were observed at room temperature under reverse bias The green electroluminescence originated from the electron impact excitation of Er 3+ ions doped in ZnO films

Development of electrolyte-free ozone sensors using boron-doped diamond electrodes.

Abstract: The electrochemical detection of dissolved ozone in water was examined using boron-doped diamond (BDD) electrodes. A well-defined reduction peak was observed at ~380 mV for H-terminated BDD, whereas it was observed at ~200 mV in the case of O-terminated BDD for an ozone solution in a 0.1 M phosphate buffer solution at pH 7. The peak potential for ozone reduction was selective with respect to oxygen reduction at both H- and O-terminated BDD electrodes, whereas it occurred at approximately the same potential as oxygen reduction at other types of solid electrodes, including glassy-carbon, platinum, and gold electrodes. Interference from chlorine was not observed in lower concentration than 300 μM ClO(-). Furthermore, in order to apply the detection technique to electrolyte-free media, BDD microelectrodes were also used. A linear calibration curve for dissolved ozone in water could be achieved between concentrations of 0.49 and 740 μM, with an estimated detection limit (S/N = 3) of 0.185 μM (S/N = 3). Excellent stability was demonstrated for repetitions of these calibration curves performed in 3 consecutive days.

Humane Orientation as a New Cultural Dimension of the GLOBE Project A Validation Study of the GLOBE Scale and Out-Group Humane Orientation in 25 Countries

Abstract: We validate, extend, and empirically and theoretically criticize the cultural dimension of humane orientation of the project GLOBE (Global Leadership and Organizational Behavior Effectiveness Research Program). Theoretically, humane orientation is not just a one-dimensionally positive concept about being caring, altruistic, and kind to others as discussed by Kabasakal and Bodur (2004), but there is also a certain ambivalence to this concept. We suggest differentiating humane orientation toward in-group members from humane orientation toward out-group members. A multicountry construct validation study used student samples from 25 countries that were either high or low in humane orientation (N = 876) and studied their relation to the traditional GLOBE scale and other cultural-level measures (agreeableness, religiosity, authoritarianism, and welfare state score). Findings revealed a strong correlation between humane orientation and agreeableness, welfare state score, and religiosity. Out-group humane orienta...
