Stain-free protein quantification and normalization
Disclosed herein are methods of protein quantification and normalization using haloalkylated tryptophan fluorescence. Complex protein samples, i.e., samples that each contain 1,000 or more distinct proteins, from diverse sources that do not have common protein profiles are treated with a halo-substituted organic compound (i.e. haloalkane) that reacts with tryptophan residues to form fluorescent products. Irradiation of the samples with ultraviolet light and the detection and quantification of the resultant fluorescent emissions from all proteins in each sample are then used to obtain comparative values for total protein content among the various samples. The values thus obtained are found to be valid indications of comparative total protein content, despite the fact that the tryptophan levels vary widely among the various proteins in any single sample and the samples, due to the diversity of their origins, tend to differ among themselves in the identities and relative amounts of the proteins that they contain. Protein samples are also normalized to correct for differences in sample dilution, sample loading, and protein transfer inconsistencies, by using stain-free detection of total protein in each of the samples, or detection of subsamples within each sample. |

Shift range controller
A shift range controller includes a target speed setter that sets a target motor speed for a motor based on an angle deviation between a current rotation position of the motor and a target rotation position based on a requested shift range. A requested duty calculator calculates a requested duty as a drive control amount for driving the motor based on the target motor speed. The target speed setter receives a feedback of the requested duty, and changes the target motor speed at a deceleration time based on the feedback of the requested duty. By changing the target motor speed based on the requested duty, the target motor speed is optimized for responding to impediment-causing factors such as temperature and friction. In such manner, the shift range switching responsiveness is improved. |

Process to create a self-organizing surface matrix
A method involves the coating of a metallic substrate with a blasting medium through sandblasting or equivalent techniques. The blasting medium is preferably a powder made of silicon nitride (or other ceramic or engineering materials). The sandblasting process allows the silicon nitride powder to form a loosely packed layer on the substrate. With additional treatment via rolling and/or sliding action against a secondary body in the presence of a liquid lubricant, the loosely packed particle layer turns into a flattened surface matrix consisting of particle clusters and irregular cavities. The silicon nitride particles are spontaneously attached to the substrate surface without the use of an adhesive agent which subsequently leads to the formation of a surface matrix exhibiting a chaotic hybrid topography with zero tensile stress when subjected to rolling/sliding contact pressure. This cluster-cavity matrix can evolve continuously (thus dynamic) and is immune to debris indentation from dirty lubricants. It is a complex, self organizing, and adaptive system. The practical value of this invention is to greatly enhance the fatigue and wear life of the bearing substrate and other objects coming into contact with the treated substrate. |

Method of amplification of a short tandem repeat locus
Short tandem repeat (STR) markers are genetic elements that are frequently used in the fields of forensic analysis, paternity determination and detection of genetic diseases and cancers. Such analysis involves the amplification of STR loci. Technically, this can be challenging due to sequence variations in the flanking regions of the locus. In the case of SE33, previous amplification efforts have failed. The present invention describes a set of primers for the amplification of SE33 and a method for the analysis of the presence and/or level of SE33, also in combination with other STRs. |
