摘要:
The present invention relates to a method for enhancing the yield of recombinant protein produced in genetically transformed plants. The invention most particularly relates to a method for preventing the undesirable proteolysis of recombinant proteins after harvest of the plant, during processing of the products from the plants. Especially, this invention focuses on introducing protease inhibitors in plants to prevent undesirable proteolysis of recombinant proteins at the time of cell disruption during the extraction process.
摘要:
The present invention relates to a method for increasing the stability of endogenous proteins recovered from plant cells or plants. The preservation of endogenous proteins integrity of endogenous protein occurs by neutralizing proteolysis in crude extracts, particularly by the use of genetic alteration of plant cells or plants that express recombinant protease inhibitors or altered activity of specific target proteases.

A roof ridge shingle unit including: a substantially elongated cover element shaped like a plurality of shingles longitudinally overlapping partially each other and having a substantially inverted V-shaped transversal cross-sectional configuration defining a pair of opposed side edges and a zenith ridge extending longitudinally therealong between the side edges, the cover element defining a top surface and an opposed bottom surface, the cover element defining longitudinally opposed first and second ends; and a first end attachment provided substantially adjacent the first end and a second end attachment provided substantially adjacent the second end. The first and second end attachments are configured and sized so that the first end attachment of the roof shingle unit is attachable to the second end attachment of a similar roof shingle units so that the roof ridge shingle units are secured to each other in a predetermined positional relationship relative to each other.

A mechanized unit is provided for digging a trench in the ground and laying elongate objects in the trench, including a motor driven vehicle, a digging wheel connected to the rear of the vehicle, and a reserve connected to the front of the vehicle and containing said elongate objects, and a guide device for laying said objects in the vicinity of the bottom of the trench, the device being connected to the vehicle, said mechanized unit further including a receptacle connected to the vehicle and containing a fine powdery material and means for feeding said material from the receptacle to the guide device so that, during formation of the trench by the digging wheel, said elongate objects are buried in the fine powdery material deposited in said trench.

A motorized road-going vehicle for making trenches may include on its chassis a device for digging a trench using a trenching wheel and a device for sucking and collecting the spoil produced while the trench is being dug. The trenching wheel is mounted so that it can pivot about an axis orthogonal to the chassis so as to occupy a working position projecting from the chassis and a transport position brought up onto the chassis.

A rackmount chassis includes removable supports that provide interior support for blades having mounting edge-to-mounting edge dimensions that are less than the full chassis width. The removable supports are mounted on parallel support plates that span the full width of the chassis. Each removable support supports an edge of at least one blade installed into the rackmount chassis. The locations of the removable supports on the parallel support plates determine the blade form factors (mounting edge-to-mounting edge dimensions) that the rackmount chassis can accept. Because the removable supports can be individually removed/installed, the configuration of the resulting rackmount component can be changed without physically removing the rackmount component from the rack in which it is mounted.

Method and device for propelling a cable or the like into a duct. According to the invention, said cable (2) is propelled into the duct (3) by the combined action of a flow of a pressurized liquid (14) and of a stream of pressurized gas (12), the pressure of said gas being greater than the pressure of said liquid.
摘要:
The present invention provides a device for digging trenches, including at least one digging wheel with a wheel framework which is connected to a vehicle by means of a mobile carriage for lowering or raising the wheel, further including: first means for causing said digging wheel to pivot about a first pivoting axis orthogonal to the plane defined by the direction of movement of the vehicle and the axis of rotation of said wheel, and second means capable of causing said wheel to pivot about a second pivoting axis orthogonal to the plane defined by said first pivoting axis and an axis parallel to the rotational axis of the wheel.
