There is conflicting evidence on the association between lower limb alignment characteristics and the incidence of running-related injury (RRI). Therefore, the primary aim of this study was to investigate the association between lower limb alignment characteristics and the incidence proportion of RRI in a convenience sample of recreational runners. A total of 89 recreational runners were includ...

The structure of the alkaline earth silicate glass CaSiO3 has been investigated using a two-dimensional 29Si NMR experiment that correlates the isotropic magic-angle-spinning (MAS) spectrum with an anisotropic off-magic-angle-spinning spectrum. Although the one-dimensional magic-angle-spinning (MAS) spectrum is completely unresolved, all five types of SiO4 tetrahedra (represented by the notatio...

T he small-angle scattering of xrays or neutrons from proteins in solution can provide important information about the structure of the protein and the nature of interactions or distance correlations among the protein molecules (1, 2). The former is encoded in the form factor [P(q)], and the latter in the structure factor [S(q)]. These functions are of great interest to the structural biology c...

[Purpose] The purpose of this study was to evaluate the correlation between intrinsic patellofemoral pain syndrome (PFPS) in young adults and lower extremity biomechanics. [Subjects] This experiment was carried out with sixty (24 men and 32 women), who are normal university students as subjects. [Methods] All subjects underwent 3 clinical evaluations. For distinguishing the intrinsic PFPS from ...

We investigate whether a search light, S, illuminating a tiny angle (“cone”) with vertex A inside a bounded region Q ∈ IR with the mirror boundary ∂Q, will eventually illuminate the entire region Q. It is assumed that light rays hitting the corners of Q terminate. We prove that: (I) if Q = a circle or an ellipse, then either the entire Q or an annulus between two concentric circles/confocal ell...

PURPOSE This research was conducted to compare supine and standing Merchant views, to observe radiographic changes of the patellofemoral joint according to weight-bearing conditions, and to evaluate correlation factors affecting patellofemoral joint indices. MATERIALS AND METHODS Forty-four patients without skeletal problems were selected for this study. Patellar tilt angle, lateral patellofe...

[1] The Scandinavian Twin Auroral Radar Experiment (STARE) coherent radar system measures the Doppler shifts caused by 1 m plasma waves in the high-latitude E region ionosphere. These Doppler velocities are here related to the electron drift velocity and ion acoustic velocity derived from measurements with the incoherent radar system European Incoherent Scatter (EISCAT). The Doppler velocity is...

Single-walled carbon nanotubes (SWCNTs) offer a range of potential applications based on their unique one-dimensional structures. Theoretical calculations shows that their electronic structures depend strongly on their chiral vector indices (n,m) which determine the diameter and chiral angle. The graphite wrapping condition n-m=3p+q generates metallic tubes for q=0, while semiconducting tubes a...

Background: The purpose of the present study was to investigate correlative and predictive relationship of lower extremity anatomical alignment, isometric hip abduction and external rotation strength with jump-landing biomechanics using Landing Error Scoring System (LESS). Methods: Anatomical alignment and isometric lower extremity muscle strength of 30 active...

OBJECTIVE To compare the value of Q angle in different positions, in the external and internal rotations of lower limbs. METHODS This is a descriptive cross-sectional study. We have evaluated 62 volunteers, 32 women and 30 men in the following positions: supine positions with parallel feet, supine with abduction (external rotation of lower limbs), and standing position with parallel feet and ...
