Agricultural Drip Irrigation,griculture are classified as in-line, with emitters manufactured into the tubing. Proper filtration is a key to successful drip irrigation system performance. Sand filters are a necessary pretreatment step when the water source is a pond or stream. The design of lateral length and diameter is evalua

Drip Irrigation System Design,cts the lowest cost alternative. The next examples focus on the economic comparison of several agricultural in-line drip products. The economic analysis includes frequency of replacement, cost, and degradation over time. Examples include the irrigation of a watermelon crop (high value with no yield

Peter Waller,Muluneh Yitayewm-cavity system is also ideal to entangle an atom to a mesoscopic coherent field made of several photons. Superpositions of coherent fields of the kind imagined by Schr?dinger in his famous cat metaphor have been generated and studied. The decoherence of these states has been observed, providing new
