Ghayn
The Arabic letter ( ar, غَيْنْ ' or ') is the nineteenth letter of the Arabic alphabet, one of the six letters not in the twenty-two akin to the Phoenician alphabet (the others being , , , , ), it represents the sound or . In name and shape, it is a variant of ʻayn (). Its numerical value is 1000 (see Abjad numerals). In the Persian language, it represents ~ and is the twenty-second letter in the new Persian alphabet. A voiced velar fricative or a voiced uvular fricative (usually reconstructed for Proto-Semitic) merged with ʻayin in most languages except for Arabic, Ugaritic, and older varieties of the Canaanite languages. Canaanite languages and Hebrew later also merged it with ʻayin, and the merger was complete in Tiberian Hebrew. The South Arabian alphabet retained a symbol for '','' 𐩶. Biblical Hebrew, as of the 3rd century BCE, apparently still distinguished the phonemes ġ /ʁ/ and ḫ /χ/, based on transcriptions in the Septuagint. For example, Gomor ...

{{unreferenced, date=August 2011 An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge. However, it detonates the primary charge (the booster), which then delivers an explosive shockwave that is sufficient to detonate the secondary, main, high-energy charge. Unlike C4 plastic explosive, not all explosives can be detonated simply by inserting a detonator and firing it. An initiator such as a shock tube, cannon fuse, or even a conventional detonator does not deliver sufficient shock to detonate charges comprising TNT, Composition B, ANFO and many other high explosives. Therefore, some form of "booster" is required to amplify the energy released by the detonator so that the main charge will detonate. At first, picric acid was ...
