Boat anchor

Boat Anchor—a slang term, used to describe an injection mold that is no longer suitable for fabricating parts. It may be because the design is obsolete or the mold is not capable of producing satisfactory parts. Note being associated with a boat anchor is not good for one s career. 

Zebra mussel is native to Eastern Europe however, it has spread all over the continent during the last 200 years [37]. In the mid 1980s, the species reached North America, where it colonized the Great Lakes and extended by the Mississippi River to the Gulf of Mexico [38], In the Flix area, local residents found some zebra mussel in 2001. The occurrence of these species in the Ebro River is accidental. In fact, the larvae probably arrived brought in the water where living baits are transported. Other pathways could have been boats or anchors [39],... 

Other failures of pipelines generally occur as a result of third party activity and natural hazards. Offshore, pipelines are generally more susceptible to fishing boats dragging their anchors on the seabed. Onshore pipelines are vulnerable to impacts from earth moving operations for construction or road grading. On occasion impacts from mobile equipment may also directly strike and damage the pipeline. 

DUKW(Refs 1 2). These vehicles proved to be very valuable during WW II for bringing men, weapons and supplies ashore from ships anchored beyond the range of enemy land-based guns. The amphibious vehicle BARC is the largest wheeled vehicle(60 tons) utilized by the US Army. When in the water it resembles a boat. The BARC can haul large bulky car goes (See also Amphtrack)... 

During prophase, the cells cytoskeleton or structural framework made of the protein tubulin breaks down into subunits. Erom these subunits, a bridge of microtubules called the spindle apparatus forms between the two pairs of centrioles as they move apart. When the centrioles reach opposite ends of the cell, they extend microtubules in all directions. Like a boat moored to a dock with multiple lines, the centriole anchors itself to... 

Sampling in valley dams over 10 m high is carried out at several predetermined points (profiles) from a boat. Marking of the sampling points by anchored buoys simplifies position fixing. Zonal sampling should be performed to follow the stratification and motion of in-flow water in reservoirs. 

The drill rig with all its components is an integral part of the ship. This vessel may be dynamically positioned over a site or anchored with up to three bows and three stem anchors. The use of a bow thruster enables anchoring without the assistance of another boat. The drill string will always be motion (heave) compensated. Heave compensation is a method employed offshore to minimize the effect of waves on the drilling and sampling process. A more thorough discussion of heave compensation will be presented in Section 5.2 A A. The second type. North Sea Type—Portable, has a portable heave-compensated... 

An antarafacial [3,3] sigmatropic rearrangement was proposed for one reaction by Miyashi, T. Nitta, M. Mukai, T. ]. Am. Chem. Soc. 1971, 93, 3441, but an alternative explanation for the experimental results was advanced by Baldwin, J. E. Kaplan, M. S. /. Am. Chem. Soc. 1971,93,3969. Even more complicated pathways can be imagined. Hansen, H.-l Schmid, H. Tetrahedron 1974, 1959, considered seven possible transition structures for the Cope rearrangement, including boat and chair suprafacial-suprafacial, twist, cross, and plane antarafacial-antarafacial transition structures, and one anchor antarafacial-suprafacial transition structure.
