Baghdad / Beirut / Cairo. Samar Hassan fed up with the power cuts that plague their neighborhoods in the Lebanese capital Beirut regularly. Samira Ahmed The Egyptian, each time a sinking feeling in my stomach when her husband moved into their slum on the outskirts of Cairo in perilous heights cable to drain to electricity for the common budget. In Iraq, in turn, led angry protests from the public against the constant blackouts in bloody clashes with security forces. In June, while one protester died and dozens more were wounded - the electricity minister, had to resign.

During the summer in the Middle East from week to week will be hot and the temperatures in some places even to 50 degrees in the shade, climb the minds of the population because of the excruciating heat increasing electricity shortage. Somewhat peaceful relations and the global triumph of consumerism raise expectations with which the crumbling infrastructure in many Arab countries can not keep up.

The Affliction separates the social classes from each other. More and more members of the middle classes can afford air conditioners, refrigerators and other appliances that eat a lot of power - especially if they all crave the same time after a refrigerated room and a cold soda. For the poor, however, the current is often not even to their huts in the evening light have.

Electricity and excavations

2. Existing utilities that cross the pipeline trench prevent shields
from being pulled forward. Pulling and resetting shields
around crossing utilities is time-consuming plus the area
around the crossing utility has to be shored in some other
way. In pit construction any existing line that crosses through
the hole is enough to prevent use of a shield.
Because most water, gas, and electric installations are
within the top 8 ft of the surface, it is possible to remove the
top shield and pull lower shields under the utilities. Shoring
or sloping still needs to be provided above the boxes.

9.6.2 Shoring Shield Size and Nomenclature
The basic elements and nomenclature of a shoring shield are shown in
Fig. 9.30. Shoring shields and boxes are described by height × length ×
wall thickness. The wall thickness is nominal. Most shields are constructed
with 3/16-in plate “skin” over tube steel ribs so the actual
wall thickness is nominal size +3/8 in. Standard heights are 2, 4, 6, and
10 ft. Standard lengths are in 2-ft increments from 10 to 32 ft. Wall

Emergency and Backup Power Sources

Not only for South Africans: Emergency and Backup Power Sources - Preparing for Blackouts and Brownouts provides invaluable information on emergency and backup power sources, as we deal with an aging power distribution system that often fails to provide reliable electrical power. The massive power outage in the summer of 2003 that affected eight states and parts of Canada exemplifies the importance of this topic.
