Characterizing Arabidopsis thaliana mutant lines that affect leaf shape and vein pattern
An optimum leaf shape and vein pattern is necessary for vascular plant success. The isolation of leaf morphological mutants of Arabidopsis thaliana has been used for leaf development studies. Auxin is a signal molecular that regulates plant development and growth processes. I have analyzed four …

Dorsal hand feature analysis: an aid to forensic human identification
… of method repeatability. The variation of the veins and surface features was explored, with regard to influences from biological characteristics, and the investigation of whether images of poor quality (representing a forensic case image) lead to a loss of data, compared to the suspect image …

Biometric Person Identification Using Near-infrared Hand-dorsa Vein Images
… the improvement of computer vision as well as pattern recognition technologies. Hand vein patterns have been recognised as a good biometric measure for personal identification due to many excellent characteristics, such as uniqueness and stability, as well as difficulty to copy or forge. This …

Dorsal knuckle crease pattern: utility for forensic human identification
… to determine whether the dorsal knuckle crease pattern may be of value within the field of forensic human identification. This was examined through three phases of research. The primary phase of research attempted to classify the pattern of the skin creases overlying the proximal interphalangeal …

Functional and developmental characterisation of matrix binding sites in decapentaplegic
… of the high affinity type I receptor thick veins, it could be demonstrated, that the variants differ only in matrix binding and not in their receptor affinity. Different matrix binding was shown by Heparin FPLC. The biological relevance of the matrix interaction of DPP was examined in …

Aspects of faulting and fracturing in brittle lithologies
… by crosscutting relationships of cemented veins and faults. The formation of vein and fault systems is characterized by re-sealing of the fractures by calcite cementation. Although restoring the systems strength to large parts, the successive fracturing events show signs for mechanical …
