CHAPTER I Introduction Over 70% of the planet is covered by water. (75% of that is salt water‚ only leaving a 25% as fresh water which can be used for consumption. 70% of the fresh water of our planet is still frozen in the icecaps of Antarctica and Greenland; while the remaining percentage is present as soil moisture‚ or it lies underground as groundwater. Main Problem How can the seawater be utilized for the consumption of different organisms? Sub problems How will the results of the said

I. LANDING GEAR SAFETY DEVICES Most airplanes with a retractable landing gear have a gear warning horn that will sound when the airplane is configured for landing and the landing gear is not down and locked. Normally‚ the horn is linked to the throttle or flap position‚ and/or the airspeed indicator so that when the airplane is below a certain airspeed‚configuration‚ or power setting with the gear retracted‚ the warning horn will sound. Accidental retraction of a landing gear may be prevented by
