Evaluation of the sinking processes for high-pressure-gas cylinders... Such forming defects are caused by excessive hardening, although the open end has been annealed with induction heating prior to the sinking operation....
Sinking-hoists synchronous balance control system in vertical shaft AbstractIn order to solve the problems existing in traditional shaft sinking-hoists, the variable-frequency adjustable-speed system was designed for the sinking-hoists firstly....
Arbitrage valuation and bounds for sinking-fund bonds with multiple sinking-fund datesThe paper tackles the problem of pricing, under interest-rate risk, a default-free sinking-fund bond which allows its issuer to recurrently retire part of the issue by (a) a lottery call at par, or (b) an open market repurchase....
Protist communities in moored long-term sediment traps (fram strait, arctic)–preservation with mercury chloride allows for pcr-based molecular genetic analyses... They can provide information on pelagic protist communities by collecting sinking plankton from the upper water column all year-round, even in remote polar oceans....
