AM is also inefficient in power usage; at least two-thirds of the power is concentrated in the carrier signal. The carrier signal contains none of the original information being transmitted (voice, video, data, etc.).

Since no idea and no literary or philosophical movement ever germinated on Persian or Arabian soil without leaving its impress on the Jews, the Persian Ghazali found an imitator in the person of Judah ha-Levi. This poet also took upon himself to free his religion from what he saw as the shackles of speculative philosop...

As mentioned above, G-proteins may terminate their own activation due to their intrinsic GTP→GDP hydrolysis capability. However, this reaction proceeds at a slow rate (≈.02 times/sec) and, thus, it would take around 50 seconds for any single G-protein to deactivate if other factors did not come into play. Indeed, there...

One disadvantage is the patient has to hold still for long periods of time in a noisy, cramped space while the imaging is performed. Claustrophobia (fear of closed spaces) severe enough to terminate the MRI exam is reported in up to 5% of patients. Recent improvements in magnet design including stronger magnetic fields...

The Pittman Formation was described originally by Öpik in 1958 who named it after the Pittman Valley, southeast of Aranda, Australian Capital Territory. It is entirely of Ordovician age and about 800 metres thick near Canberra, but at Captains Flat it is over 1,200 metres thick. The lower levels are greywacke, exposed ...

Some strains of "E. coli", for example O157:H7, can produce Shiga toxin (classified as a bioterrorism agent). The Shiga toxin causes inflammatory responses in target cells of the gut, leaving behind lesions which result in the bloody diarrhea that is a symptom of a Shiga toxin-producing "E. coli" (STEC) infection. This...

Following the Asia Minor Campaign (1919–22), the Greeks were in urgent need of more weapons and tried to get Mannlicher–Schönauer rifles from every possible source in order to replace war losses (almost 50% were captured by the Turks, leaving slightly over 104,000 to 108,000 M1903 and M1903/14s).

Dry-ice blasting involves propelling pellets at extremely high speeds. The actual dry ice pellets are quite soft, and much less dense than other media used in blast-cleaning (i.e. sand or plastic pellets). Upon impact, the pellet sublimates almost immediately, transferring minimal kinetic energy to the surface on impac...
