چکیده
A microcontroller based advanced technique was designed and developed to protect the house hold appliances, such as water-pump from fluctuation of line voltage. This device was tested with upper and lower cutoff voltages set at ±10% of the normal supply voltage (220V, AC) and with an over-load current up to 10A. The current sensor’s output was monitored by the PIC12F675 microcontroller and used analog to digital protocol. A ‘C’ language program was developed to control the function of microcontroller, using PCWH compiler.

Non-coding RNAs (ncRNAs), especially for microRNAs (miRNAs), have been widely s tudied as crucial negative regulatory molecules. Long noncoding RNAs (lncRNAs) also have attracted the attention of researchers due to their potential contribution in multiple essential biological processes. To understand th e p otential in teractions between miRNAs, l ncRNAs and mRNAs a nd their p otential r oles i...
