Cássio van den Berg (born 1971) is a Brazilian botanist.
 He is noted for work in orchid classification and evolution, especially great changes in the generic circumscriptions of ornamental orchids in the genus "Cattleya", based on DNA studies for the subtribe Laeliinae.
 Based on this studies, he proposed a fusion of the genera "Cattleya", "Laelia" (only Brazilian species), and "Sophronitis".
 In Laeliinae, the studies pointed out to the separation of subtribe Ponerinae, and the transfer of "Dilomilis" and "Neocogniauxia" to Pleurothallidinae.
 He also worked in the taxonomy of other orchid genera, such as "Acianthera", "Baptistonia", "Bulbophyllum", "Cymbidium", "Encyclia", "Galeandra", "Isabelia" and "Pleione".
 In 2004, he described a new genus of Laeliinae, "Adamantinia" Van den Berg & C.N.Gonç.
 Currently he is full professor and curator of the Laboratory of Plant Molecular Systematics.
Albert Jan van den Berg (born 14 June 1949 in Amsterdam) is a founding partner of Hanotiau & van den Berg in Brussels (since 2001), a Emeritus Professor of Law at the Erasmus University, Rotterdam, a visiting Professor at Georgetown University Law Center, Washington DC and at the University of Tsinghua School of Law, Beijing and a member of the Advisory Board and Faculty of the Geneva Master of Laws in International Dispute Settlement (MIDS), Geneva.

De Speld ("The Pin") is a Dutch news satire website.
 The website publishes satirical articles and videos parodying the style and content of regular news outlets.
 "De Speld" was founded in 2007 by Jochem van den Berg and Melle van den Berg (no relationship).

Space Shuttle missions designated STS-3xx (officially called Launch On Need (LON) missions) were rescue missions which would have been mounted to rescue the crew of a Space Shuttle if their vehicle was damaged and deemed unable to make a successful reentry.
 Such a mission would have been flown if Mission Control determined that the heat shielding tiles and reinforced carbon-carbon panels of a currently flying orbiter were damaged beyond the repair capabilities of the available on-orbit repair methods.
 These missions were also referred to as Launch on Demand (LOD) and Contingency Shuttle Crew Support.
 The program was initiated following loss of Space Shuttle "Columbia" in 2003.
 No mission of this type was launched during the Space Shuttle program.
