Problem: Tajikistan's rivers, such as the Vakhsh and the Panj, have great hydropower potential, and the government has focused on attracting investment for projects for internal use and electricity exports. Tajikistan is home to the Nurek Dam, the highest dam in the world. Lately, Russia's RAO UES energy giant has been working on the Sangtuda-1 hydroelectric power station (670 MW capacity) commenced operations on 18 January 2008. Other projects at the development stage include Sangtuda-2 by Iran, Zerafshan by the Chinese company SinoHydro, and the Rogun power plant that, at a projected height of 335 metres (1,099 ft), would supersede the Nurek Dam as highest in the world if it is brought to completion. A planned project, CASA 1000, will transmit 1000 MW of surplus electricity from Tajikistan to Pakistan with power transit through Afghanistan. The total length of transmission line is 750 km while the project is planned to be on Public-Private Partnership basis with the support of WB, IFC, ADB and IDB. The project cost is estimated to be around US$865 million. Other energy resources include sizable coal deposits and smaller reserves of natural gas and petroleum.

Problem: Under the Bretton Woods system established after World War II, the value of gold was fixed to $35 per ounce, and the value of the U.S. dollar was thus anchored to the value of gold. Rising government spending in the 1960s, however, led to doubts about the ability of the United States to maintain this convertibility, gold stocks dwindled as banks and international investors began to convert dollars to gold, and as a result the value of the dollar began to decline. Facing an emerging currency crisis and the imminent danger that the United States would no longer be able to redeem dollars for gold, gold convertibility was finally terminated in 1971 by President Nixon, resulting in the "Nixon shock".
What was the value of the Nixon investors linked to?

Problem: Known as the fraternal birth order (FBO) effect, this theory has been backed up by strong evidence of its prenatal origin, although no evidence thus far has linked it to an exact prenatal mechanism. However, research suggests that this may be of immunological origin, caused by a maternal immune reaction against a substance crucial to male fetal development during pregnancy, which becomes increasingly likely after every male gestation. As a result of this immune effect, alterations in later-born males' prenatal development have been thought to occur. This process, known as the maternal immunization hypothesis (MIH), would begin when cells from a male fetus enter the mother's circulation during pregnancy or while giving birth. These Y-linked proteins would not be recognized in the mother's immune system because she is female, causing her to develop antibodies which would travel through the placental barrier into the fetal compartment. From here, the anti-male bodies would then cross the blood/brain barrier (BBB) of the developing fetal brain, altering sex-dimorphic brain structures relative to sexual orientation, causing the exposed son to be more attracted to men over women.
