Dec 09, 2020 · Iran, a mountainous, arid, and ethnically diverse country of southwestern Asia. The heart of the Persian empire of antiquity, Iran has long played an important role in the region as an imperial power and as a factor in superpower rivalries. Modern Iranian culture owes itself in part to a renaissance in the 8th century. Iran's Nuclear Program Timeline and History NTIIranian Centrifuge Model Collection. Iran's interest in nuclear technology dates to the 1950s, when the Shah of Iran received technical assistance under the U.S. Atoms for Peace program. While this assistance ended with the 1979 Iranian Revolution, Iran remained interested in nuclear technology and developed an extensive nuclear fuel cycle, including sophisticated enrichment capabilities Iran's parliament approves bill to stop nuclear inspectionsDec 01, 2020 · TEHRAN, Iran (AP) Irans parliament on Tuesday approved a bill that would suspend U.N. inspections of its nuclear facilities and require the government to boost its uranium enrichment if European signatories to the 2015 nuclear deal do not provide relief from oil and banking sanctions.
Iran-Iraq War (198088), prolonged military conflict between Iran and Iraq. Estimates of total casualties range from 1,000,000 to twice that number. Fighting was ended by a 1988 cease-fire, though the resumption of normal diplomatic relations and the withdrawal of troops did not take place until 1990. Saffron Classification and Grades Spanish, Afghan, and ISO, a federation of national standards bodies, sets the saffron classification standards. ISO 3632 exclusively deals with saffron and sets up 4 grades of color intensity such as IV (lowest), III, II and I (purest and finest saffron quality).Saffron Classification gauges the level of 440-nm light absorbency by using samples of dray saffron.High absorbencies mean that there is a high Scholaro GPA CalculatorD is a passing grade in most public schools (primary and secondary schools) in the U.S., but usually not in college. College courses with a grade of D cannot be transferred, but can be re-taken. Most high schools require a minimum 1.0 GPA to graduate. Most undergraduate programs require a
