Abstract:
Methods and compositions for identifying novel pesticidal gene homologues are provided. Specifically, the methods of the invention comprise systematically designing oligonucleotide primers that are specific for a pesticidal gene of interest and performing successive rounds of PCR amplification of nucleic acid material from a microorganism, particularly a Bacillus thuringiensis strain, to identify novel homologues of known pesticidal genes. Oligonucleotide primers that can be used to practice the present methods are further disclosed.
Abstract:
The present invention discloses a pulling device for a container inspection system including a pulling vehicle (1) arranged inside an inspection passage, a winch (5) and wire tension mechanisms (6,6′). Front and rear ends of the pulling vehicle are connected to a wire rope so as to drive the pulling vehicle to move back and forth inside the inspection passage. The wire rope connected to front and rear ends of the pulling vehicle is wound around a wire tension mechanism arranged at front and rear ends of the inspection passage and is turned around by a swerving pulley (2) which is positioned at the same horizontal plane as that of the wire rope, the pulling vehicle, and the wire tension mechanisms, then the wire rope passes through the vertical pulley block, and finally it is connected to a single winding drum (4) of the winch (5) and wound around the single winding drum (4) respectively. Compared with the prior arts, the present invention is advantageous in reduction in equipment investment and decrease in area occupied by the pulling device. Further, the inspection operation can be carried out more reliably and safely.

Abstract:
A pixelated photolithography mask is optimized for high resolution microelectronic processing. In one embodiment, the invention includes synthesizing a pixelated photolithography mask, applying a pixel flipping function to the mask, comparing the resulting mask to a desired result, and synthesizing an optimized pixelated binary photolithography mask using the function.
Abstract:
A process for preparing the d-threo isomer of methylphenidate hydrochloride comprising converting d,l-threo methylphenidate hydrochloride to the free base form in a first step, resolving the free base prepared in the first step with (R)-(-)-1,1'-binaphthyl-2,2'-diyl hydrogen phosphate to obtain the phosphate salt enriched with the d-threo isomer of methylphenidate in a second step, basifying the phosphate salt to obtain the free base form of the d-threo isomer of methylphenidate in a third step, converting the free base to the hydrochloride salt form of the d-threo isomer of methylphenidate in high optical purity in a fourth step, and recrystallizing the hydrochloride salt form to obtain the desired d-threo isomer in a higher optical purity. An alternative embodiment relates to the preparation of the d-threo isomer of methylphenidate hydrochloride utilizing the hydrochloride salt form of the racemic mixture of threo-methylphenidate directly.
