Survey says Investments in agricultural technology ought to be directed to Africa’s smallholder farmers in an effort to increase food security after decades of low financing, the U.N. Meeting on Trade and Development said in a written report on Wednesday, Reuters reports .N. Information Centre writes. The report notes that Africa’s smallholder farmers can reap the benefits of new systems such as low-price drip irrigation and plastic material water tanks to store runoff, as opposed to modern irrigation systems that may increase crop yields but were created more for larger farms, the news service notes .Warren, M.D., Jonathan D.F. Wadsworth, Ph.D., Nicholas W. Hardwood, M.D., Janice L. Holton, M.D., and John Collinge, M.D.1 The transmissible agent, or prion, is thought to comprise misfolded and aggregated forms of the standard cell-surface prion protein. Prion propagation is thought to occur through seeded proteins polymerization, a process involving the binding and templated misfolding of normal cellular prion protein. Identical processes are named relevant to other increasingly, more common neurodegenerative diseases. In prion and additional neurodegenerative disorders, the aggregates of misfolded proteins in the central nervous system are highly heterogeneous, happening as amyloid plaques, even more diffuse deposits, and soluble species.
