Comments on “A New Look at the Israeli Cloud Seeding Experiments”

Discussion of Reports on Cloud Seeding Experiments

The work on cloud seeding which has been described in this Symposium is new to me. I find it extremely gratifying to encounter such well designed and carefully conducted experiments in which the principles of randomization have been scrupulously adhered to. A few of the speakers appear to think that there is some conflict between a "statistical" experiment, fulfilling the requirements of experi...

A Review of Cloud Seeding Experiments to Enhance Precipitation and Some New Prospects

Water is one of the most basic commodities on earth sustaining human life. In many regions of the world, however, traditional sources and supplies of ground water, rivers and reservoirs, are either inadequate or under threat from ever-increasing demands on water from changes in land use and growing populations. In many countries water supplies frequently come under stress from droughts and incr...

Caffeine effect on adenosine deaminase catalysis: A new look at the effect of caffeine on adenosine deaminase activity

The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...
