摘要:
A safety device for a cantilevered beam pivotally mounted adjacent one end thereof to a support surface is adapted to bridge the beam and the support surface and is structured so that when coupled to the beam and support surface, the safety device maintains the beam in a substantially fixed cantilevered condition until a downward force exceeding a threshold is applied to the beam and thereafter controls downward pivoting of the beam.
摘要:
The present invention relates to a nucleic acid sequence encoding a mutated hydroxyphenylpyruvatedioxygenase (HPPD) which exhibits improved tolerance to HPPD inhibitors, to a chimeric gene which comprises this sequence as the coding sequence, and to its use for isolating or obtaining plants which are resistant to certain herbicides.

Disclosed is an instrument case for use by an operator suspended from a harness. The instrument case is preferably attached to the operator's thigh by means of a thigh strap which is rotatably attached to the instrument case. Pull straps are attached to the instrument case at one end and to the operator's harness or belt at the other end. By adjusting the tension in the pull straps, the operator may adjust the orientation of the instrument touch screen to optimize its visibility and accessibility.

Method of ion exchange cobalt recovery. Raffinate including cobalt, zinc, copper, nickel and ferric iron is produced. In the raffinate, the pH is raised, the solids are removed and ferric iron is reduced. A copper recovery ion exchange unit is loaded with ion exchange resin selective for copper. Raffinate is fed into the copper recovery ion exchange unit which is regenerated to recover substantially all copper. A cobalt/nickel/zinc recovery ion exchange unit is loaded with another ion exchange resin selective for cobalt. Raffinate is fed into the cobalt/nickel/zinc recovery ion exchange unit, the ion exchange resin holding cobalt, zinc and nickel, and then displaced. Cobalt/zinc eluent is fed into the cobalt/zinc/nickel recovery ion exchange unit to elute the cobalt and zinc in a cobalt/zinc solution, and then displaced. Nickel eluent is fed into the cobalt/zinc/nickel recovery ion exchange unit to elute the nickel.

The present invention relates to a process for the recovery of cobalt comprising: (i) providing a high tenor cobalt solution wherein the high tenor cobalt solution comprises cobalt and nickel; (ii) contacting the high tenor cobalt solution with an N-(2-hydroxypropyl)picolylamine resin to load the N-(2-hydroxypropyl)picolylamine resin with cobalt and nickel; (iii) eluting the cobalt from the loaded N-(2-hydroxypropyl)picolylamine resin; and (iv) eluting the nickel from the loaded N-(2-hydroxypropyl)picolylamine resin.
摘要:
The invention concerns a nucleic acid encoding a chimeric hydroxyphenyl pyruvate dehydrogenase (HPPD) enzyme formed from a nucleic acid encoding the N-terminal portion of a first plant HPPD in combination with nucleic acid encoding the C-terminal portion of a second plant HPPD, wherein the N-terminal portion and the C-terminal portion are separated by a linker peptide. The nucleic acid can be used to transfom a cell or an organism, such as a plant, to provide tolerance to herbicides. The invention also concerns methods of making and using plants transformed with the nucleic acid.
