With the growth in popularity of video gaming in the early 1980s, a new genre of video game guide book emerged that anticipated walkthroughs. Written by and for gamers, books such as The Winners' Book of Video Games (1982) [1] and How To Beat the Video Games (1982) [2] focused on revealing underlying gameplay patterns and translating that knowledge into mastering games.

The Kuwaiti dinar (Arabic: دينار كويتي , code: KWD) is the currency of Kuwait.It is sub-divided into 1,000 fulūs. [2]As of 2023, the Kuwaiti dinar is the currency with the highest value per base unit, with KD 1 equalling US$3.26, [3] ahead of the Bahraini dinar with BD 1 equalling US$2.65 and Omani rial at US$2.60.
Cyclooctadiene iridium chloride dimer is an organoiridium compound with the formula [Ir(μ 2-Cl)(COD)] 2, where COD is the diene 1,5-cyclooctadiene (C 8 H 12). It is an orange-red solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis. [1]
Chlorobis(cyclooctene)iridium dimer is an organoiridium compound with the formula Ir 2 Cl 2 (C 8 H 14) 4, where C 8 H 14 is cis-cyclooctene.Sometimes abbreviated Ir 2 Cl 2 (coe) 4, it is a yellow, air-sensitive solid that is used as a precursor to many other organoiridium compounds and catalysts.
Infrared photodissociation (IRPD) spectroscopy uses infrared radiation to break bonds in, often ionic, molecules (photodissociation), within a mass spectrometer. [1] In combination with post-ionization, this technique can also be used for neutral species.
Iridium acetylacetonate is the iridium coordination complex with the formula Ir(O 2 C 5 H 7) 3, which is sometimes known as Ir(acac) 3. The molecule has D 3 -symmetry. [ 2 ] It is a yellow-orange solid that is soluble in organic solvents.
The rial (Persian: ریال ایران, romanized: riyâl-è Irân; abbreviation: Rl (singular) and Rls (plural) [15] [16] or IR [17] in Latin; ISO code: IRR) is the official currency of Iran. It is subdivided into 100 dinars , but due to the rial's low purchasing power the dinar is not practically used.
