Background: The transportation of fish is a common practice in aquaculture. However, the results significant stress that can cause mortality and disease outbreaks due to compromised immune status. To ameliorate effect this stress, it advocated suitable antioxidant be supplemented before subjecting transportation. Objectives: present experiment was performed evaluate melatonin on haematological ...
In classical optical time domain reflectometries (OTDRs), for sensing an 200-km-long fiber, the optical pulses launched are as wide as tens of microseconds to get enough signal-to-noise ratio, while it results in a two-point resolution of kilometers. To both reach long sensing distance and sub-kilometer resolution, we demonstrated a long-haul photon-counting OTDR using a superconducting nanowir...
