Seismic imaging characteristics of a prototype electrically driven, linear synchronous motor-based, vertical-force seismic vibrator (“e-vib”) were evaluated at site in the Netherlands. The system weighs 1.65 t and excites signals with peak force 6.7 kN. Data recorded along two collocated geophone-based nodal landstreamer microelectromechanical - MEMS-based sensor 2D profiles. To obtain broad ba...

During mammalian development, left-right (L-R) asymmetry is established by a cilia-driven leftward fluid flow within a midline embryonic cavity called the node. This 'nodal flow' is detected by peripherally-located crown cells that each assemble a primary cilium which contain the putative Ca2+ channel PKD2. The interaction of flow and crown cell cilia promotes left side-specific expression of N...

background: axillary nodal spread is an established prognostic factor in breast cancer. axillary nodal dissection and subsequent pathological examination is considered the gold standard technique of assessing the axilla for metastatic disease. a minimum of ten level i axillary nodes are required to be examined before an axillary specimen can be reliably labeled as disease free. this recommendat...

Stretching process of sheet metals in both cases of axisymmetric and non-axisymmetric is analyzed. A rigid-plastic, normal anisotrop material is assumed and large strain formulation is applied. Triangular elements are used and stiffness equations of elements are obtained from virtual work principle. These nonlinear equations are linearized by Newton-Raphsons method and are solved by Gaussian el...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...

The diffusion quantum Monte Carlo DMC method is the most accurate approach available for calculating the total energies of solids and large molecules.1 Energy gradients are also of great significance in quantum mechanical calculations, because they give the forces on atoms which may be used to relax structures and perform molecular dynamics simulations. Progress in such calculations using DMC m...

on the verge of the constitutionalist revolution in iran, the three social forces existing in the socio-political arena were competing with each other and at the same time, struggling with the monarchy to increase their share of power: independent intellectuals, traditional followers of religion, and merchants. this rivalry set the scene for a discursive battle in which, each social force was t...
