Purpose: The purpose of this study was to identify the important parameters for a model-based design optimization method through comparison of different biomechanical environments and various dental implant models. Materials and Methods: Finite element analysis (FEA) was applied to model a mandibular bone implant system. Essential parameters, such as, cortical bone properties, boundary conditio...

Brown (I950) defined the features of the superior oblique tendon sheath syndrome and reported five cases. He postulated that the restriction in elevation of the affected eye in the adducted position was caused by a congenitally short anterior tendon sheath of the superior oblique muscle. As the eye moved into adduction, this ligament-like sheath became taut and strongly opposed the action of th...

[Purpose] It has been reported that exercises focusing upon the transversus abdominis (TrA) ameliorate low back pain (LBP). We investigated whether expiratory muscle training (EMT) can promote activity of the TrA to the same degree as the abdominal drawing-in manoeuvre (ADIM) in elderly individuals. [Subjects and Methods] Twenty-one elderly subjects (9 males, 12 females; mean age, 84.9 ± 6.6 ye...

Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet been examined for the WAIS-IV is the bifactor mod...

The collagen architecture is the major determinant of the function and mechanical behavior of cardiovascular tissues. In order to engineer a functional and load-bearing cardiovascular tissue with a structure that mimics the native tissue to meet in vivo mechanical demands, a complete understanding of the collagen orientation mechanism is required. Several methods have been used to visualize col...

An attempt has been made to study and analyze the performance of a rough hyperbolic slider bearing under the presence of a magnetic fluid lubricant. The magnetic field is oblique to the stator and the bearing surfaces are considered to be transversely rough. The roughness of the bearing surface is characterized by a stochastically random variable with non-zero mean, variance and skewness. The c...

Both medial and anterolateral plate applications have been described for the treatment of distal tibia fractures, each with distinct advantages and disadvantages. The objective of this study was to compare the biomechanical properties of medial and anterolateral plating constructs used to stabilize simulated varus and valgus fracture patterns of the distal tibia. In 16 synthetic tibia models, a...

The contention is examined that the oblique effect, i.e., the well-known performance deficit in detecting orientation difference in oblique lines as compared to vertical and horizontal ones, has its origin in a relative deficiency of neurons with obliquely-oriented receptive fields in the primary visual cortex. Psychophysical observations demonstrate a prominent oblique effect also in visual ta...

The superior oblique tendon sheath syndrome was first described by Brown (I950). The essential feature is a limitation of elevation in adduction caused by a short or inadequately mobile anterior segment of the superior oblique tendon and its sheath. Treatment of the condition is indicated if an abnormal head posture is necessary in order to maintain an adequate field of binocular single vision;...

The psychological oblique effect, a well-known phenomenon that humans and some mammals are more visually sensitive to cardinal (vertical and horizontal) contours than to oblique ones, has commonly been associated with the overrepresentation of cardinal orientations in the visual cortex. In contrast to the oblique effect, however, Essock et al. [E.A. Essock, J.K. DeFord, B.C. Hansen, M.J. Sinai,...
