The enhancement of teacher immunity in a professional development course: Contributions from supervisory observation and the observer.

Classroom observation has been reported to be stressful for language teachers since it can disrupt the equilibrium and push the teachers towards maladaptive language teacher immunity. The present study is an attempt to shed light on the way classroom observation and a professional development (PD) course on classroom observation contribute to language teacher immunity development through self-organization lens. To this end, the researchers in the current study designed an explanatory sequential mixed method study and 13 novice language teachers were invited to fill language teacher immunity scale before and after a professional development course.

First report of fesavirus 4 detection from cats in Japan.

GeSbSeTe-based high extinction ratio optical modulator.

Control of managed pressure drilling systems using nonlinear predictive generalized minimum variance approach based on a Volterra model.

This paper proposes a nonlinear predictive generalized minimum variance (NPGMV) control scheme for automatic control of the managed pressure drilling (MPD) systems in the presence of disturbances. Since the exact model of the system is not usually available in practice, the hydraulic flow model of MPD is described by an autoregressive second-order Volterra model. The conventional least-squares method is applied to input-output data, thereby identifying the Volterra model.

Spectral response, dark current, and noise analyses in resonant tunneling quantum dot infrared photodetectors.

Reduction of dark current at high-temperature operation is a great challenge in conventional quantum dot infrared photodetectors, as the rate of thermal excitations resulting in the dark current increases exponentially with temperature.

In this paper, we use a physical model developed by the authors recently to design a proper resonant tunneling barrier for quantum infrared photodetectors and to study and analyze the spectral response of these devices.

Cardiac Surgery Anesthesia And Systemic Inflammatory Response.

Cardiac surgery is associated with the development of a systemic inflammatory response. Inflammation represents the response of the body to tissue injury and in normal circumstances is a controlled humoral and cellular response that will lead to control of infection and wound healing. In some instances this response may become exaggerated, ultimately leading to additional tissue injury and the development of organ dysfunction.
