The aim of this study was to determine the extent of asymmetry of spinal segment mobility in canoeists. Moreover, the relationship between this parameter and racing speed was analyzed. The study included 18 canoeists with a mean age of 16.4 years. Mobility of cervical, thoracic and lumbar spine, in sagittal, coronal and transverse planes, was measured with the aid of a tensometric electrogoniom...

Loth and Henneberg (1996, Am. J. Phys. Anthropol. 99:473-487) identified a single morphological feature of the mandible, the presence or absence of a distinct flexure or angulation of the posterior margin of the mandibular ramus at the level of the occlusal plane, which appears to be an extraordinarily accurate predictor of sex. Using only this feature, Loth and Henneberg were able to predict s...

A Comb Drive Actuator is a basic actuation device of MEMS. MEMS applications often require large force, large displacement, low-power and energy-efficient actuators. Low power consumption is highly desirable not only for economic reasons, but also for heat generation considerations. In this paper, different types of structural design of Comb Drive Actuator that is Fixed-Fixed Flexure Beam, Crab...

This work deals with the kinematic conception and the mechanical design of ultra-high precision robots, which are at present costly to develop, both in time and money. The aim of this paper is thus to introduce a new modular concept of kinematics which allows to significantly reduce the time-to-market and a new double-stage flexure-based pivot. Regarding the modular concept of kinematics, this ...

Flexure occurs on intermediate geologic timescales (∼1 Myr) due to volcanic-island building at the Island of Hawaii, and deformational response lithosphere is simultaneously elastic, plastic, ductile. At shallow depths low temperatures, elastic deformation transitions frictional failure faults where stresses exceed a threshold value, this complex rheology controls rate manifested by earthquakes...

A simple visual field method of determining ,the amount of fiattening of a flattened flexure fold is described. The method allows estimation of the pre-flattening thicknesses and dips of the deformed beds, so that original thicknesses of sequences and the total shortening of the layers by folding may be calculated,

The ability to replicate physiological hemodynamic conditions during in vitro tissue development has been recognized as an important aspect in the development and in vitro assessment of engineered heart valve tissues. Moreover, we have demonstrated that studies aiming to understand mechanical conditioning require separation of the major heart valve deformation loading modes: flow, stretch, and ...

This case report presented a simultaneous right colon tumor detected perioperatively in patient who developed ileus due to metastatic left the preoperative period. A seventy-six-year-old man was admitted with epigastric pain, nausea, and vomiting. There tenderness defense on deep palpation epigastrium. On computed tomography, there were multiple hypodense lesions liver, mass at level of splenic...

In order to estimate Weibull parameters in the statistical fracture theory as truly material properties independent of specimen geometry and loading mode, first is transformed into ordinary distribution function under certain approximation. Then standardized format introduced enable modulus single parameter for estimation via maximum likelihood method. The method using strength data synchroniza...

Alveolar soft part sarcoma (ASPS) is a very rare sarcoma, report <1% of all soft tissue tumor. Majority of cases were young adult and tumor occurred in lower extremities and trunk. Here, we present a case of 53-year-old Thai female with rapidly glowing mass over her right forearm. The magnetic resonance imaging scan demonstrated a hypervascular mass with multiple feeding vessels located in flex...
