We present a measurement of the standard model CP violation parameter sin2 phi(1) based on a 29.1 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson is fully reconstructed as a J/psi K(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psi K(L), or J/psi K(*0) decay and the flavor of the accompanying B meson is identified from its decay products. From the asymmetry in the distribution of the time intervals between the two B meson decay points, we determine sin2 phi(1) = 0.99+/-0.14(stat)+/-0.06(syst). We conclude that we have observed CP violation in the neutral B meson system.

Encouraging nurses to learn more about oral care using diverse educational resources will enhance their knowledge and improve their practice. Nursing administrators are encouraged to establish policies and procedures for oral care of intubated patients based on the type of patients cared for, in addition to holding in-service training, with a view to enhancing the quality of oral care for critically ill patients.

The values healthcare teams emphasise with regard to safety can serve to improve safety performance. Having an understanding of the concept of and interventional measures for safety climate allows healthcare providers to ensure the safety of their operations and their patients.

Distributed monitoring is essential to effective actuation and vibration control of shell-type precision structures. In this paper, electro-mechanics and sensitivities of distributed segmented piezoelectric shell sensors applied to ring shells are evaluated. Since sensor signals are modal dependent, natural modal characteristics, emphasizing the circumferential modes, are studied first. Then, with the segmentation technique, distributed segmented sensors with various lengths are designed and their signal generations resulting from modal strains are evaluated. The total output signals includes four components: 1) a bending strain induced signal by the circumferential oscillatory amplitude, 2) a bending strain induced signal by the transverse oscillatory amplitude, 3) a membrane strain induced signal by the circumferential oscillatory amplitude and 4) a membrane strain induced signal by the transverse oscillatory amplitude respectively at the transverse and circumferential modal component frequencies. Furthermore, the sensor sensitivities are divided into: 1) the transverse modal sensitivity and 2) the circumferential modal sensitivity. Parametric studies (e.g., ring radius, sensor thickness, ring thickness and sensor segment length) are conducted to evaluate the spatial signal distributions and component signal generations of segmented ring sensors. All data indicate that ring’s circumferential, not transverse, component mode dominates the total signal generation.
