The Central Cairo-Suez District (CCSD) has a special urban extension, particularly the fast growth of the new Cairo and New Administration Capital of Egypt (NACE).Accurate discrimination of the lithology and surface and near-surface structures will be a valuable contribution to the geotechnical characterization of the foundation rocks and geohazard
After the Fall: Legacy Effects of Biogenic Structure on Wind-Generated Ecosystem Processes Following Mussel Bed Collapse
Blue mussels (Mytilus edulis) are ecosystem engineers with strong effects on species diversity and abundances.Mussel beds appear to be declining in the Gulf of Maine, apparently due to climate change and predation by the invasive green crab, Carcinus maenas.As mussels die, they create a legacy of large expanses of shell biogenic structure.In Maine,
Study on the Manufacturing Process of Low Temperature Ductile Iron Casting Gear Box Used for Locomotive
Taking the QT400-18 L low temperature ductile iron gear box used for locomotive as example,through the control of the element content of the material,the graphite spheroidization is more fully.At MOUSSE GEL the same time,the samples are heat treated to ensure Bamboo Body Brush the stability of mechanical property.In the casting process,the casting
Multiple Access Control for Cognitive Radio-Based IEEE 802.11ah Networks
The proliferation of Internet-of-Things (IoT) technology and its reliance on the license-free Industrial, Scientific, and Medical (ISM) bands have rendered radio spectrum scarce.The IoT can nevertheless obtain great advantage from Cognitive Radio (CR) technology for efficient use of a spectrum, to be implemented in IEEE 802.11af-based primary netwo
