Abstract:
The present invention provides methods for rapid forensic analysis of mitochondrial DNA by amplification of a segment of mitochondrial DNA containing restriction sites, digesting the mitochondrial DNA segments with restriction enzymes, determining the molecular masses of the restriction fragments and comparing the molecular masses with the molecular masses of theoretical restriction digests of known mitochondrial DNA sequences stored in a database.
Abstract:
The present invention provides a method for rapid identification and quantitation of bacteria by amplification of a segment of bacterial nucleic acid followed by analysis by mass spectrometry. The compositions provide for characterization of the molecular masses and base compositions of bacterial nucleic acids which are used to rapidly identify bacteria.
Abstract:
An electrically non-conductive wheel chock for restraining the movement of a wheel which contains a body, an arm attached to the body extending outwardly and upwardly from the body, and a device for preventing the movement of the wheel check upon the rail. The top portion of the wheel chock body contains a first ramp, a top deck, and a second ramp. The bottom portion of the wheel chock body contains a downwardly-extending leg and an arcuate surface joined to the leg. The body has a compressive modulus of at least about 400,000 pounds per square inch.
Abstract:
With reference to FIG. 1, a continuous mixer 1 comprises a housing 2 formed with intersecting cylindrical chambers 3 and 4, and a pair of substantially parallel shafts 5 and 6, mounted for rotation within the housing. Paddle members 10 and 11 are mounted on the shafts 5 and 6 so that when the shafts are rotated, each in the same direction, the peripheral parts of the paddle members on one shaft are wiped by the cooperating parts of the paddle members on the other shaft, and vice versa. As shown in FIGS. 4a and 4b, the end faces of each paddle member are formed with lobes, the number of lobes at one end face of the member being different to that at the opposite end face. The arrangement results in continuous distribution, re-orientation and dispersal of material flowing through the mixer.
