Isra'iliyyat
In hadith studies, Isra'iliyyat (in Arabic: اسرائیلیات "of the Israelites") are narratives assumed to be of foreign import. Although indicating such stories develop from Jewish sources, narratives designated as Isra'iliyyat might also derive from other religions such as Christianity or Zoroastrianism. Isrā'īlīyāt are especially in modern times critizised as "unislamic", while they had been commonly used in pre-modern times. These narratives appear frequently in Qur'anic commentaries, Sufi narratives and history compilations. They are used to offer more detailed information regarding earlier prophets mentioned in the Bible and the Qur'an, stories about the ancient Israelites, and fables allegedly or actually taken from Jewish sources. Muslim scholars generally classify the narratives of the Isra'iliyyat into three categories:

Atmospheric-pressure Chemical Ionization
Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (105 Pa), commonly coupled with high-performance liquid chromatography (HPLC). APCI is a soft ionization method similar to chemical ionization where primary ions are produced on a solvent spray. The main usage of APCI is for polar and relatively less polar thermally stable compounds with molecular weight less than 1500 Da. The application of APCI with HPLC has gained a large popularity in trace analysis detection such as steroids, pesticides and also in pharmacology for drug metabolites.

USFS Grampus
USFC Grampus was a fisheries research ship in commission in the fleet of the United States Commission of Fish and Fisheries, usually called the United States Fish Commission, from 1886 to 1903 and then as USFS Grampus in the fleet of its successor, the United States Bureau of Fisheries, until 1917. She was a schooner of revolutionary design in terms of speed and safety and influenced the construction of later commercial fishing schooners. Grampus′s home ports were Woods Hole and Gloucester, Massachusetts . During her 31-year career, Grampus made significant contributions to the understanding of the mackerel fishery off the United States East Coast , Canada , and the British colony of Newfoundland. She also investigated the tilefish population, conducted fishery investigations in the Gulf of Mexico, and contributed to fish culture work in New England to propagate the mackerel, cod, and lobster.

Ring Expansion and Ring Contraction
Ring expansion and ring contraction reactions in the course of organic synthesis refer to a set of reactions which can lead to the expansion or contraction of an existing ring. This often makes it possible to access structures that would be difficult if not impossible to synthesise with single cyclization reactions. Ring expansions are valuable because they allow access to larger systems that are difficult to synthesize through a single cyclization due to the slow rate of formation. Ring contractions are useful for making smaller, more strained rings from larger rings. Expansions are classified by the mechanism of expansion and the atom(s) added; contractions are characterized simply by the reactive intermediate which performs the contraction.
