MicroElectroMechanical Systems, MEMS, are systems based on a range of techologies whereby tiny mechanical elements, both sensors and actuators, can be implemented.It turns out that these elements have excellent system properties.The elements are often interfaced to microelectronical driving or sensing components (ICs) by appropriate packaging or on the same silicon wafer. The semiconductor silicon is not only good for making electronics but its material properties are extremely good.Thus, Micro electromechanical systems (MEMS) refer to a collec ....etc

ASSESSMENT OF IMPACTS, ADAPTATION, AND VULNERABILITY
TO CLIMATE CHANGE IN EGYPT


Introduction

The inhabited area in Egypt does not exceed 3.5% of the total area and is confined to the narrow strip which boarders the main course of the River Nile from Aswan in the south to Cairo in the north plus the Nile Delta which covers the area from Cairo to the shore line of the Mediterranean Sea between the cities of Damietta in the east and Rosetta in the west.
The main agricultural regions in Egypt are; Nile Delta ....etc

Abstract


To speak the name of the dead is to make him live again
Ancient Egypt civilization lasted over 3000 years.

Egyptian monuments have been around so long
that their monuments were ancient even in Greek
and Roman times…. but one key question has
always loomed: how were the pyramids built?

The Pyramids are one of the Seven Wonders of the Ancient World. Decorating the Nile waterfront they loom over passing boats. They are the lasting reminders of the Pharaohs that once ruled Egypt ....etc

Egypt's military-led government faced a major challenge after two days of clashes between Muslims and Christians in which state media reported 12 people died and 238 were injured.
Egypt's worst sectarian strife since 13 people died on March 9 when a church was burned was triggered by rumors Christians had abducted a woman who converted to Islam.
The army said that 190 people would be tried in military courts over the violence that erupted on Saturday.
On Sunday, hundreds of ....etc

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS) have been continuously providing new and improved paradigms in the field ....etc
