OBJECTIVES To examine gender and regional differences in health expectancies based on the measure of mobility. METHODS Health expectancies by gender and region were computed by Sullivan's method from the fourth Thai National Health Examination Survey (2009). A total of 9,210 older persons aged 60 years and older were included. Mobility limitation was defined as self-reporting of ability to pe...

background: patients with heart disease experience limited activities of daily living (adl). this is a cross-country comparison of the additive effects of socioeconomics, health behaviors, and the number of medical comorbidities on disability among patients with heart disease. methods: the current study used a cross-sectional design. data came from the research on early life and aging trends an...

Variations of marine current speed can lead to strong fluctuations in the power extracted by a marine current turbine (MCT). During short-time period, swell effect is the main cause for the current speed variations. Conventional tip speed ratio Maximum Power Point Tracking (MPPT) algorithm will require the MCT to accelerate or to decelerate frequently under swell effect, which can cause severe ...

Discussing the state of the art of current limitation in medium voltage range shows the limits and drawbacks of today's current limiting techniques. Focusing on up-to-date research projects in the field, the major part of this paper explains various kinds of current limitation by means of super conducting materials. The two major principles, resistive and inductive limiters, are introduced as w...
