According to a 2007 BSA and International Data Corporation (IDC) study, the five countries with the highest rates of software piracy were: 1. Armenia (93%); 2. Bangladesh (92%); 3. Azerbaijan (92%); 4. Moldova (92%); and 5. Zimbabwe (91%). According to the study's results, the five countries with the lowest piracy rates were: 1. U.S. (20%); 2. Luxembourg (21%); 3. New Zealand (22%); 4. Japan (23%); and 5. Austria (25%). The 2007 report showed that the Asia-Pacific region was associated with the highest amount of loss, in terms of U.S. dollars, with $14,090,000, followed by the European Union, with a loss of $12,383,000; the lowest amount of U.S. dollars was lost in the Middle East/Africa region, where $2,446,000 was documented.

Who did a study in 2007 regarding the five countries with the highest rates of software piracy?
Answer: BSA and International Data Corporation

There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.

Which type of power does require three-phase transmission?
Answer: AC

Juan Atkins, an originator of Detroit techno music, claims the term "house" reflected the exclusive association of particular tracks with particular clubs and DJs; those records helped differentiate the clubs and DJs, and thus were considered to be their "house" records. In an effort to maintain such exclusives, the DJs were inspired to create their own "house" records.

Why were DJs inspired to create their own house records?
Answer:
differentiate the clubs and DJs
