Current trends in surgical intervention favour a minimally invasive approach, in which complex procedures are performed through very small incisions. Specifically, in neurosurgery there is a need for minimally invasive keyhole access, which conflicts

Publication rate of patents can be a useful measure of innovation and productivity in science and technology. Patenting activity in new technological fields follows a sigmoid (S-shaped) path. Qualitative and quantitative models in management and econ

A new strain-sensing structure inspired from insect's (especially the Fly) propricoception sensor is devised. The campaniform sensillum is a strain-sensing microstructure with very high sensitivity despite its small dimension (diameter ~10Pm in a rel

The fracture properties of small, cylindrical samples of endosperm machined from single kernels of several varieties of wheat were measured using three methods: compression, wedge fracture and indentation. In addition, dynamic compression tests were

Genetically modified tobacco plants ( Nicotiana tabacum ‘Samsun’) with antisense cinnamyl alcohol dehydrogenase DNA, produce secondary xylem of a reduced tensile stiffness. These plants were grown alongside control plants. The stems of the plants

Tobacco plants (Nicotiana tabacum‘Samsun’) have been grown with an antisense CAD (cinnamyl alcohol dehydrogenase) gene. This modifies lignin production, resulting in lignin with a greater aldehyde content which is easier to extract chemically. Th

Lignin in the cell walls of woody tissue has a much lower crosslink density in tobacco wood than in tree wood. This causes tobacco wood to show very different viscoelastic behaviour. With the aid of genetically modified plants, it is shown that the l

The egg capsules of dogfish are largely constructed from laminae of parallel orientated collagenous fibrils arranged longitudinally, near-diagonally, and near-transversely. The fibrils show an axial (D) period of about 40 nm. These characteristics fa

Minimally Invasive (MI) surgery represents the future of many types of medical intervention (keyhole neurosurgery, natural orifice trans-luminal endoscopic surgery, etc.). However, the shortcomings of today's surgical tools fuel the need for the deve
