In our previous study the inclination of nasolacrimal canal in relation to Frankfurt horizontal plane has been analysed on 71 anatomically preparated human skulls by introducing the probe through canal. The results of that study showed that the alpha angle in the frontalplane was greater than 91 degrees in 27% of cases, i.e., nasolacrimal canals descend diverging in relation to the median plane...

OBJECTIVES To evaluate the clinical and radiographic results and complications relating to patients undergoing arthroscopic treatment for femoroacetabular impingement by means of an extracapsular approach. METHODS Between January 2011 and March 2012, 49 patients (50 hips) underwent arthroscopic treatment for femoroacetabular impingement, performed by the hip surgery team of the Orthopedic Hos...

In this paper we generalize the notion of helix in three-dimensional Euclidean space, which define as that curve $\alpha$ for there is an $F$-constant vector field $W$ along forms a constant angle with fixed direction $V$ (called axis helix). We find natural equation and geometric integration helices where orthogonal to its axis.

Miscut surfaces of layered crystals can exhibit a stair-like sequence terraces having periodic variation in their atomic structure. For hexagonal close-packed and related crystal structures with an {\alpha}{\beta}{\alpha}{\beta} stacking sequence, there have been long-standing questions regarding how the differences adatom attachment kinetics at steps separating affect fractional coverage {\alp...

This article pushes the role of sine and cosine functions beyond traditional purpose determining sides a right triangle, into realm lengths any triangle with practically same ease. Extended are formulated dependent on two angles (instead one) — sin*(α,γ) cos*(α,γ)—that allow (via direct application) computation shorter scalene as resul...

We examine the decay of the 3.03 MeV state of (8)Be evaporated from an excited projectilelike fragment following a peripheral heavy-ion collision. The relative energy of the daughter alpha particles exhibits a dependence on the decay angle of the (8)Be(*), indicative of a tidal effect. A comparison of the measured tidal effect with a model suggests a measurable nuclear proximity interaction.

Leaf area index (LAI) - defined as one half of the total green leaf area per unit ground surface area - can be determined by direct or indirect methods. Three major sources of errors exist in indirect LAI measurements: within-shoot clumping, beyond-shoot clumping and non-photosynthetic components. The effect of non-photosynthetic components on LAI measurements can be described by the woody-to-t...

The bootstrap current produced by fusion born alpha particles is obtained retaining effects of slowing down drag, pitch angle scattering, and arbitrary aspect ratio. The result is presented both as a summation of a rapidly converging series and a simple Pade approximation good for arbitrary aspect ratio. Quantitative results are derived using International Thermonuclear Experimental Reactor (IT...

Eukaryotic DNA is organized into nucleosomes by coiling around core particles of histones, forming a nucleosomal filament. The significance for the conformation of the filament of the DNA entry/exit angle (alpha) at the nucleosome, the angle of rotation (beta) of nucleosomes around their interconnecting DNA (linker DNA) and the length of the linker DNA, has been studied by means of wire models ...

We report time-resolved small angle neutron scattering (t-SANS) measurements of the topological relaxation of Couette shear-induced stacked L(alpha) lamellar states to their multiconnected isotropic L3 sponge equilibrium phases in a surfactant bilayer membrane system. Comparison of this structural relaxation time to the interval between diffusive membrane contacts, as determined from dynamic li...
