This paper proposes a strategy for detecting unintentional islanding operations (IOs) in distribution networks (DNs) with distributed generation (DG), which eliminating the non-detection zone (NDZ). hybrid method achieves zero-NDZ by taking advantage of both passive and active methodologies an inverter-based DG scenario. The passive-based part proposed considers settings low thresholds is activ...

AIM To investigate whether the measurement of serum zinc may improve the detection of prostate cancer (PCa) in men who had total prostate-specific antigen (PSA) levels higher than 4.1 ng/mL. METHODS A mass screening for PCa of 3940 men over 50 years old was undertaken using total serum PSA. Of the 190 men (4.8%) with elevated PSA, 143 (3.6%) underwent a transrectal ultrasonography (TRUS)-guid...

This paper contributes to clarifying the conditions under which electrode position for surface EMG detection is critical and leads to estimates of EMG variables that are different from those obtained in other nearby locations. Whereas a number of previous works outline the need to avoid the innervation zone (or the muscle belly), many authors place electrodes in the central part or bulge of the...

Chemical warfare agents are toxic weapons and emergency prehospital medical care providers should be well prepared, trained, and equipped to give response. Personnel need to be aware of the following medical issues regarding prehospital management of a chemical attack, event recognition, incident medical command and control, safety and protection, decontamination, isolation of the incident area...

The in vivo low-dose responses of zebrafish (Danio rerio) embryos to 150 kV X-rays with different levels of hardness were examined through the number of apoptotic events revealed at 24 h post fertilization by vital dye acridine orange staining. Our results suggested that a triphasic dose response was likely a common phenomenon in living organisms irradiated by X-rays, which comprised an ultra-l...
