Abstract:
The present disclosure generally pertains to a multiplex method for analyzing samples comprising using polynucleotide amplification to produce amplified products wherein one or more target sequences are tagged with a non-interfering, non-canceling target-specific polynucleotide identification tag, pyrosequencing the amplified products through the non-canceling target-specific polynucleotide identification tag sequence to detect the presence of one or more specific polynucleotide identification tags. The presence of a specific polynucleotide identification tag being correlated with the presence of a specific target sequence.
Abstract:
The invention provides a bogie which comprises a bolster, two side frames and four constant contact dampers, two sides of two ends of the bolster are respectively provided with a wedge pocket; the four constant contact dampers are respectively arranged in four wedge pockets, and each of the four constant contact dampers comprises a wedge and a damping spring; the damping spring is arranged in an inner cavity of the wedge; one end of the damping spring bears against a top inner surface of the inner cavity of the wedge, and the other end of the damping spring bears against a bottom plate of the wedge pocket, wherein the bogie further comprises four through holes and four ejectors which respectively correspond to the four constant contact dampers; the through holes are arranged on the bottom plate, and the position of each of the four through holes on the bottom plate corresponds to the position where the damping spring bears against the bottom plate and a load spring of the bogie; and one end of the ejector penetrates into the damping spring, and the other end of the ejector bears against the load spring through the through hole. The bogie of the present invention solves the technical problem that the deformation of the damping springs keeps constant whether a car is empty or loaded in the prior art, and thus improves the damping effect of the bogie.
Abstract:
The present invention provides pathogen-resistant transgenic plants and methods of making the plants. The transgenic plants display enhanced resistance to a variety of fungal, bacterial and viral plant pathogens due to expression of a gene that increases the unsaturated fatty acid content of the plant's cells, as compared with an equivalent, but non-transformed plant. The preferred embodiment of the invention is a plant expressing a heterologous &Dgr;-9 desaturase gene from yeast, which particularly increases cytosolic quantities of 16:1, 16:2 and 18:1 fatty acids.
Abstract:
The present invention discloses a freight car bogie and a freight car. The freight car bogie comprises two wheel sets, two side frames arranged at outer side of said wheel sets, and a bolster fixedly connected to center position of each of said two side frames, respectively. The freight car bogie further comprises a K-shaped supporting device, wherein said K-shaped supporting device passes through preset holes on two sides of an abdominal region of said bolster; a first upper end and a second upper end, as well as a first lower end and a second lower end of said K-shaped supporting device are elastically connected with said two side frames respectively; and said first upper end and second upper end, and said first lower end and second lower end are respectively symmetrical with respect to a center line of said bolster. The K-shaped supporting device of the present application may not pass through the middle part of the bolster so that a reinforcing rib for bearing vertical load can be disposed on the middle part of the bolster, thereby increasing the anti-lozenge-distortion rigidity of the bogie as well as improving the strength of the bolster for bearing the vertical load.
