Saffron (Crocus sativus L.) in the light of biotechnological approaches: A review

January 2014

Saffron (Crocus sativus L.) is a sterile triploid plant belonging to the Iridaceae (Liliales, Monocots). Saffron is a spice derived from the flower and has for decades been the world's most expensive spice. Saffron is propagated by corms as the flowers are sterile and fail to produce viable seeds. A corm survives for only one season, producing up to ten "cormlets" that eventually give rise to new plants....

The law of universal attraction with momentum exchange between objects and microparticles

October 2013

The law of universal attraction has been used widely. However, how two objects attract each other is still a riddle. Hypotheses, such as gravitons, universal repulsion, sub-photon seas, etc., all have flaws, and do not deal with the basic reason why there is such a law. In this paper, suppose: (1) microparticles at a certain speed, moving like thermal motion of molecules, are distributed in space; (2) the objects are...
