This paper presents the design of a mechanical transducer for a new kind of optical-fiber accelerometer based on birefringence variation. Vibration-induced fiber deformation modifies the birefringence within the fiber and hence the state of polarization of the light. To deform the fiber a mechanical transducer has to be made. This article compares analytically different transducers using either...

When teeth and their supporting structures are subjected to impact trauma, the resultant injury manifests either as a separation or a crushing injury or a combination of both (1) (Fig. 1). Separation injuries are exemplified by displacement of teeth during which there is cleavage of tissues such as the periodontial ligament (PDL). This occurs during avulsions and extrusive luxations. Damage to ...

Replantation of an amputated limb is generally contraindicated in crushing and traction injuries. Injury to muscle tissue and skin also creates difficulties in coverage, and bony fractures may shorten limb length which can impede lower extremity function. Numerous cases have been reported on the successful replantation of the lower limb in children; however, review of previous English literatur...

Neuroinflammation is involved in the death of retinal ganglion cells (RGCs) after optic nerve injury. The purpose of this study was to determine whether systemic simvastatin can suppress neuroinflammation in the optic nerve and rescue RGCs after the optic nerve is crushed. Simvastatin or its vehicle was given through an osmotic minipump beginning one week prior to the crushing. Immunohistochemi...

estimate the proportion of fines generated during the blasting process. The proposed framework is based on the combination of two Rosin-Rammler based distribution functions to model the full range of fragments expected to be produced during this process. This particular approach, which has been successfully applied for a number of years by the Julius Kruttschnitt Mineral Research Centre (JKMRC)...

In this study, the crashworthiness performance of a multi-cell column designed from B1500HS boron steel with three different hardness values and six regional hot-formed designs were compared in terms passenger safety. Energy absorption peak crushing force columns examined by impact simulations under oblique loading. “T25 heat-treated column” gave highest energy value, while "O25 column" lowest ...

Pilot studies revealed promising results regarding crushing virtual cigarettes to reduce tobacco addiction. In this study, 91 regular smokers were randomly assigned to two treatment conditions that differ only by the action performed in the virtual environment: crushing virtual cigarettes or grasping virtual balls. All participants also received minimal psychosocial support from nurses during e...

In this paper, dynamic simulation and analysis for designing the soft landing of a lunar lander is focused. The primary objective of the lunar lander is to land safely on the surface of moon, without causing the lunar lander to topple and must attenuate the landing loads to preclude damage to the lander structure. The dynamic structural model of lunar lander is modelled and simulation described...

This study investigates the motor pattern and head movements during feeding of a durophagus shark, the bonnethead Sphyrna tiburo, using electromyography and simultaneous high-speed video. Sphyrna tiburo feeds almost exclusively on hard-shelled crabs, with shrimp and fish taken occasionally. It captures crabs by ram feeding, then processes or reduces the prey by crushing it between molariform te...
