‘l.THEFOLLOWING describes a relatively simple amid inexpensive modification of the Beckman No. 2980 fluorescence attachment for the Beckman DIT spectrophotometer which permits rapid and easy imiterchange of both primary and secondary filters and increases the flexibility and adaptability of this instrument in fluorimetric analysis. The filter plate assembly for the secondary filters as original...

An analytical study is performed to investigate the effects of chemical reaction and radiation on unsteady MHD flow past an exponentially accelerated vertical plate with variable temperature and variable mass diffusion in the presence of applied transverse magnetic field. It is assumed that the effect of viscous dissipation is negligible in the energy equation and there is a first order chemica...

Arthropods have hair plates that are clusters of mechanosensitive hairs, usually positioned close to joints, which function as proprioceptors for joint movement. We investigated how angular movements of the antenna of the cockroach (Periplaneta americana) are coded by antennal hair plates. A particular hair plate on the basal segment of the antenna, the scapal hair plate, can be divided into th...

This work studies the mixed convection heat transfer from a vertical plate in bidisperse porous media with constant wall temperature. The two-velocity two-temperature model is used to derive the governing equations. The effects of the mixed convection parameter, the inter-phase heat transfer parameter, the modified thermal conductivity ratio, and the permeability ratio on the heat transfer and ...

A thin plate of bone usually separates coronoid and olecranon fossa in the distal end of humerus. In some humerii this bony plate is perforated to form an aperture. This present study was conducted on 500 dried adult humerii. The incidence of septal aperture, its shape, transverse diameter and vertical diameter was measured. The septal aperture was found in 31% of humerii. The incidence was mor...

[1] The planform of sublithospheric convection is studied by a 3-D linear stability analysis of longitudinal rolls in the presence of vertical shear. Rayleigh numbers up to 10 are considered. The transition Rayleigh number over which longitudinal rolls are unstable is derived as a function of surface velocity. Effects of nonlinear vertical shear are shown to be insignificant unless nonlinearity...

BACKGROUND The high loads on adolescent athletes' musculoskeletal system are known to cause morphological and degenerative changes in bone, intervertebral discs and joints. It has been suggested that the cam deformity of the proximal femoral head originates from a subclinical slipped capital femoral epiphysis (SCFE) as a result of non-physiological loading. The perichondrial fibrocartilaginous ...

In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...

Square plate with adjustable needle pointer (5). The Glossary of Prosthodontic Terms defines the physiologic rest position (PRP) as “the mandibular position assumed when the head is in an upright positi...
