Mesquites (Prosopis spp.) are thorny leguminous shrubs or trees native to Southwest Asia, Africa, and predominantly North and South America. Introduced as beneficial plants to India, Pakistan, South Africa, Egypt, Kuwait, Australia, U.S.A. (Hawaii), and Brazil, some Prosopis species have become invasive in some of these countries. Mechanical and chemical control methods implemented in the U.S.A...
Eigen’s quasi-species model describes viruses as ensembles of different mutants of a high fitness ‘‘master’’ genotype. Mutants are assumed to have lower fitness than the master type, yet they coexist with it forming the quasi-species. When the mutation rate is sufficiently high, the master type no longer survives and gets replaced by a wide range of mutant types, thus destroying the quasi-speci...
Increasing trend in global population and climate changes are driving forces to shift toward the use of vertical farms with artificial lighting (VFALs). The main downside of VFALs is inefficient electrical usage. High efficiency and economy cost of light-emitting diodes (LED) are going to make VFALs a promising type of farming in future. Each individual species needs unique light treatment in o...
