In Phase Compensation of Sag and Swell Voltage by using Dynamic Voltage Restorer

International Journal of Scientific Research in Science, Engineering and Technology, 2019
Today most of the industries and customers are using sensitive and sophisticated electrical equipment based on semiconductor devices, these may causes power quality disturbance. The major problems are voltage sag and swell. The sag and swell not only occur by disturbed power quality but also due to high system tapping at point of common coupling.

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

Arthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

A Return to Normality: A Descriptive Qualitative Interview Study Exploring the Patient Experience of Gout Flare Resolution

Arthritis Care &Research, EarlyView.
Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...
