Since the 1970s, Sahel region has been struck by severe droughts that brought suffering to human populations. Scientists also observed declining rainfall leading desertification in zone. Against this backdrop, 2007, several African states launched international Great Green Wall (GGW) project aimed create a strip of forest from Senegal Djibouti, crossing areas mostly devoted pastoralism. We exam...

Thin sections of wound-healing potato tuber tissue were stained with rabbit antibody prepared against a suberization-associated anionic peroxidase and then stained with a goat anti-rabbit antibody-fluorescein conjugate. When these sections were examined with an epiilluminating fluorescence microscope, bright green fluorescent linear deposits were observed on the inner side of cell walls in the ...

T HE displays of the European race of the Green-winged Teal (Anas crecca crecca) have been studied intensively (Lorenz, 1953, 1958; Lorenz and von de Wall, 1960; von de Wall, 1963) b u no detailed description has been t published for the North American race (A. c. caroknensis) . Some displays of carolinensis have been described (e.g., Sutton, in Bent, 1923; Johnsgard, 1955), but in general it h...

Linear landscape elements, such as ditches, hedgerows, lines of trees and field margins, provide important habitats and ecosystem services and function as ecological infrastructure for species within agricultural landscapes. Spatial maps of the distribution of these elements are needed to better represent landscape structure within regional scale environmental assessments. We present wall-to-wa...

In order to better solve the problems of heating and environment, author proposes a new Generation 5 technology wall green energy application ther?mal system, its main feature is coating type carbon fiber, which heats up by connecting electrode, so that indoor temperature can be kept comfortable. The stability accuracy thermal system are demonstrated through specific experiments. experiment sho...
