background: linear and angular measurements such as a point, nasion, b point (anb) angle and wits appraisal index are not accurate enough to evaluate sagittal relationship of the jaws. the aim of this study was to evaluate and compare the range of ì and â angles in 6-17-year-old children of isfahan, having normal occlusion. materials and methods: this was an analytical descriptive study. for th...

The study uses DSP as the core and develops agile tracking and surveillance system. It includes overall design of the system, construction of the hardware and compilation of the software. The system hardware consists of DC, color camera, cradle head, SEED-VPM642 DSP development board or pan-tilt-zoom control system. The paper analyzes common algorithms of motion target detection. According to t...

PURPOSE To study the biomechanical characteristics (percent stretch, stiffness, and ultimate load) of 2 distal fixation techniques for an active tendon implant used in the reconstruction of flexor tendons. METHODS We evaluated percent stretch after cyclical loading and at failure, stiffness during load-to-failure, and peak load of 28 bone-prosthesis junctions using cadaveric canine middle pha...

This paper describes the design and first experimental results of a novel test setup to measure the impact response of a rotating tire. The test setup is based on a tire on tire principle, which requires less space than a classic drum (rigid rotating cylinder). The setup is used to analyse mechanisms of tire/road noise during road impact excitations, such as a cobbled roads, joints of a concret...

measurements of the tilt angle of potential fields can be a useful aid to their interpretation. there are several varieties of the methods in use, such as tilt angle, and the derivative of tilt angle. tilt angle filters are used for exact edge detection of the rectangular bodies artificially by writing a matlab code. the gravity effects of these models are computed by standard algorithms. the e...

Interactions between CD4O and its ligand, CD1S4 (CD4OL, gp39), have been shown to play a central role in the regulation of humoral immunity. Recent evidence suggests that this ligand-receptor pair also plays an important role in the induction of cell-mediated immune responses, in cluding those directed against viral pathogens, intracellular parasites, and alloantigens. The contribution of this ...

Hydrogen is a clean fuel which has the potential to drastically decarbonize energy supply chain. However, hydrogen storage currently key challenge; one solution this problem geo-storage, with very large quantities of H2 can be stored economically. Possible target formations are deep coal seams, and permeability parameter determines how fast injected withdrawn again. it well known that gas injec...

abstract   background: the purpose of this study was to evaluate the significance of the q angle with respect to the patella position. we assess the correlation between the q angles (calculated by clinical exam) in different positions and ct indices (with more impression on tttg).   method: atotal number of 68 knee joints of 50 cases entered the study. clinical examination was used to measure q...
