Nanotechnological Aspects for Next-generation Wound Management provides detailed, up-to-date literature on nanotechnology's role in wound management and its applications using nanoparticles, nanocomposites, carbon-based nanostructures and nanomaterials. Scaffolds, three-dimensional approaches, skin tissue engineering, and polymer-based films are discussed to treat wounds. This one-of-a-kind reference is ideal for health practitioners, clinicians and researchers who will find the book to be excellent reference material for updates on recent trends in nanotechnology for wound management.
Small ruminants, especially goats contribute meat, milk, fiber and other functions that are significant to the productivity, stability and sustenance of many farming systems. Goat keeping in tropical countries is undergoing a transformation from the traditional extensive browse-based feeding system to intensive stall feeding system mainly because of intensification of agriculture, shrinkage of grazing lands and reclamation of fallow lands for alternate use. Hence, cereal straws are increasingly being used as basal feeds for goats in the arable areas of the tropics. The World Health Organization (W.H.O) has been promoting a movement for "Saving plants for saving lives." Efficiency of utilization of poor quality roughages can be maximized by the supply of deficient nutrients like nitrogen, micro nutrients etc. in the ration of animals. In this context, the role of medicinal plants, especially fenu greek seeds, as feed additives, in the ration of animals is of vital significance in the countries, where small land holdings and large ruminant densities result in a severe problem of feed availability from more conventional sources like oil cakes and cereal by products.
A plant disease is a dynamic process where a living or nonliving entity interferes with the normal functions of a plant over a period of time. Things that happen just once, like lawnmower blight or lightning strikes, are not considered diseases, but rather injuries. Plant diseases result in visible symptoms that can help diagnose the disease or disorder. Disease epidemics can also threaten entire plant species. Exotic pests can threaten the continued existence of a species. Historical examples of destructive plant disease epidemics include three American tragedies: American chestnut blight, Dutch elm disease and butternut canker. Along with these three diseases some other diseases like palm lethal yellowing, oak wilt, cypress canker and Xylella outbreak caused severe epidemic.
Wood decay is a deterioration of wood by primarily enzymatic activities of microorganisms. For practical purposes, fungi are the only agents of wood decay. Fungi which grow on wood are sometimes called "lignicolous" fungi. But why develop a set of keys limited to fungi utilizing wood as a substrate? After all, being lignicolous does not define a taxonomic category. Lignicolous fungi include ascomycetes and basidiomycetes and a large number of classes and orders within each of these groups. Most of these taxa include both lignicolous and terrestrial species. Rather than taxonomy, the keys focus on the biological activity holding this otherwise disparate group of fungi together: their ability to degrade cellulose and lignin, the major components of wood. Forest trees and valuable landscape trees can be infected and rotted by these fungi. Knowing the species growing on a tree can help the forester determine the likely extent of loss. Different species are associated with different amounts of decay in the tree. Additionally, some species are restricted to sapwood and will not affect the merchantable volume of heartwood. Some fungi can decay sound wood; others decay only decaying wood.
