The distribution of organic cores, cones, cone junctions and pores in the egg shells of wild birds
Journal of Zoology, 1978Egg shells from 14 widely different species of wild birds were examined, using collodion casts of the inside surface of the shell. Organic cores, cones, cone junctions and pores were counted and in each case measurements of nearest neighbour distances were taken. Shell thickness was also measured.It was found that, using mean values for each egg shell,

Cone Shell Toxins and the Mechanisms of Their Pharmacological Action
1989The present review mainly focusses on our recent findings on the structure and mechanism of action of bioactive compounds from cone shells. Cone shells are divided into three groups according to their major prey organisms: worm-eating (vermivorous), shellfish-eating (molluscivorous), and fish-eating (piscivorous). Each species has a venom that reflects

Shell restraint to ring buckling at cone-cylinder intersections
Engineering Structures, 1997A study is presented of the out-of-plane buckling strength of rings attached to cone-cylinder intersections. Simple formulae which can be used to estimate the stiffness of the rotational restraint provided by adjacent shell walls are first developed from a finite element parametric study.

Derivation of Conduction Heat Transfer in Thin Shell Cones
SAE Technical Paper Series, 1998<div class="htmlview paragraph">The thermal design of unmanned satellites and manned spacecraft require the knowledge of heat conduction and radiation of complex geometrical shapes. These complex shapes are usually made up of the more common geometries such as flat rectangular plates, flat polygon plates, triangular plates, cones, disks ...

Stability Analysis of Plate-Cone Reticulated Shell
Applied Mechanics and Materials, 2011This paper carries out stability analysis on plate-cone reticulated shell considering geometrical nonlinearity of cooperating work between plates and members. In this paper, stability behavior of different kinds of plate-cone reticulated shell considering geometrical nonlinearity is analyzed by using the software ANSYS, tracking complete process ...

Evisceration With Eversion of the Scleral Shell and Muscle Cone Positioning of the Implant
American Journal of Ophthalmology, 1987Six patients underwent a new surgical procedure to repair extruding evisceration implants. The scleral shell was everted and used as an anterior wall for the placement of a donor sclera-encased implant within the muscle cone. Early results showed good cosmesis and no recurrent extrusions.

Initial cone-in-shell fast-ignition experiments on OMEGA
Physics of Plasmas, 2011Fast ignition is a two-step inertial confinement fusion concept where megaelectron volt electrons ignite the compressed core of an imploded fuel capsule driven by a relatively low-implosion velocity. Initial surrogate cone-in-shell, fast-ignitor experiments using a highly shaped driver pulse to assemble a dense core in front of the cone tip were ...

Continuum Analysis for Plate-Cone Spherical Reticulated Shell
Advanced Materials Research, 2011Plate-cone reticulated shell is a new type of space structures with good mechanical behavior and technical economy. In this paper, a continuum analysis method for plate-cone spherical reticulated shell which is equated to three layers thin shell is put forward.
