Penetration force measurements in the central nervous system with silicon electrodes
… the dimpling effect that is due to the insertion force. A method which can reduce the penetration force can also reduce dimpling and the resulting tissue damage. There are two objectives in this thesis. One is to measure the penetration force with Michigan electrodes, which are silicon based …

Influence of penetration force in clay soils due to speed rate effect
This research discusses the effects of penetration rate on the penetration resistance in clayey soils for five different speeds of penetrations. In order to install the pile through hydraulic system, it is crucial to understand the required penetration force needed to do the job. Generally, the …

Drosophila suzukii (Matsumura) (Diptera: Drosphilidae): Risk Assessment For An Invasive Vinegar Fly In Virginia Vineyards
… varieties. More eggs were laid in grapes as penetration force decreased. Penetration force and not skin thickness was the limiting factor for oviposition. Survivorship of eggs laid in intact grapes was analyzed and survivorship to adulthood was dependent upon variety and survivorship usually …

Relationship between cutting parameters and bit geometry in rotary cutting
… relationship between cutting parameters (cutting force, penetration force, specific energy, specific respirable dust) and the bit geometry parameters (angle of the bit tip, bit tip size and shape of the bit) in order to reduce the amount of specific respirable dust generated and the specific …

Effects of bit geometry in multiple bit-rock interaction
… was advanced at 0.14 in/sec of advance. Cutting force, penetration force, rate of advance and respirable dust were measured during the cutting process. Specific energy and specific dust were also calculated for each experiment.

Effects of priming and stage of development on vigor and longevity of muskmelon (Cucumis melo L.) seeds
… envelope tissue prior to radicle emergence. Less force was required to puncture primed seed pieces than non primed. The penetration force and energy required to puncture the perisperm envelope tissue decreased gradually during imbibition, increased steadily during seed development and dry storage, …

Investigation of Needle-Tissue Interaction during Ultrasonic Needle Intervention
… effects with the reduction of insertion force, needle deflection and tissue damage; (2) ultrasound perception with the ability to detect the loading condition in operation by electrical impedance and frequency change. Finally, an anaesthesia case study was performed on needle …

Enhanced biopsy and regional anaesthesia through ultrasound actuation of a standard needle
… and additionally benefits in reducing the penetration force. However, in order to make it clinically viable, further work is required to make it compliant with the medical environment. The piezocrystals tested under practical conditions although offer extraordinary piezoelectric properties, …
