Abstract Many Egyptian cities are influenced by environmental stress from air pollution, noise, traffic jams, and the scarcity of green spaces. Green roofs represent one ways to achieve sustainability as a result environmental, social economic benefits they provide. The research aims identify most important roles that roof technology can provide challenges it faces in market. This deals with st...

BACKGROUND Neurulation is driven by apical constriction of actomyosin cytoskeleton resulting in conversion of the primitive lumen into the central canal in a mechanism driven by F-actin constriction, cell overcrowding and buildup of axonal tracts. The roof plate of the neural tube acts as the dorsal morphogenetic center and boundary preventing midline crossing by neural cells and axons. METHO...

Green roofs are often promoted as a mean to counter the negative environmental effects of urbanization on nature and increase amount green space in cities. enhance aboveground biodiversity, especially herbivores pollinators. However, if what way they support belowground more specifically soil fauna, is rarely studied. Therefore, we evaluated diversity dominant group Collembola (springtails), tw...
