The distribution in color and absolute magnitude is presented for 55,158 galaxies taken from the Sloan Digital Sky Survey in the redshift range 0.08 < z < 0.12, as a function of galaxy number overdensity in a line-of-sight cylinder of transverse radius 1 h−1 Mpc. In all environments, bulge-dominated galaxies (defined to be those with radial profiles best fit with large Sérsic indices) form a na...

The establishment of anteroposterior (AP) polarity in the early mouse epiblast is crucial for the initiation of gastrulation and the subsequent formation of the embryonic (head to tail) axis. The localization of anterior and posterior determining genes to the appropriate region of the embryo is a dynamic process that underlies this early polarity. Several studies indicate that morphological and...

We present a finite-volume formulation for the lattice Boltzmann method (FVLBM) based on standard bilinear quadrilateral elements in two dimensions. The accuracy of this scheme is demonstrated by comparing the velocity field with the analytical solution of the Navier-Stokes equations for time dependent rotating Couette flow and Taylor vortex flow. To demonstrate the flexibility of the scheme, w...

The present paper deals with the thermal effect model of temperature distribution in dermal layers of elliptical shaped human limbs involving two uniformly perfused tumor in dermis layer. Here the tumor is characterized by uncontrolled rates of metabolic heat generation. The normal tissues are characterized by self controlled metabolic heat generation. It is assumed that first there was only on...

1 Introduction Filament winding is a popular production technique for composite structures. Cylinder pressure vessel with elliptical dome is an efficient product which can make full use of tensile strength of fiber. To achieve the most efficient use of the reinforcement material the fiber should be placed in the maximum load directions or in geodesic path. This is not always achievable as the f...

In order to solve the limitation of cylindrical geared linkage in trajectory realization, this paper make the non-circular gear pair and double crank hinge five-bar as closed combination, and to probe the feasibility and method of designing non-circular gear based on the given position points in five-bar linkage trajectory region. The discrete rotation angle sequences of non-circular gear pair ...

The physical nature of the initial transition to three-dimensionality of #ow past a circular cylinder has been the subject of considerable debate in the literature. Of several proposed mechanisms, the possibility of classi"cation as an elliptical instability is re-examined in this article. Detailed Floquet analysis of the transition shows clear evidence of the growth of an elliptic instability ...

The failure of harmonic gear drive is mainly caused by the fatigue fracture flexible wheels and damage bearings. In this paper, stress sensitivity life characteristics with thin-walled vulnerable components are studied. Firstly, structure wheel a B3-80 general reducer designed, finite element model established using ANSYS software, analysis results compared theoretical calculations to verify co...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

We reviewed medical records from select wildlife rehabilitation facilities in California to determine the prevalence of injury in California Brown Pelicans (Pelecanus occidentalis), gulls (Larus spp.), and pinniped species (Zalophus californianus, Mirounga angustirostris, and Phoca vitulina) due to fishing gear entanglement and ingestion from 2001 to 2006. Of 9,668 Brown Pelican, gull, and pinn...
