Discontinuity effects at cone-cone axisymmetric shell junctions

Thin-Walled Structures, 2002
In this paper, the problem of a conical shell axisymmetrically intersecting another conical shell, such that the vertices of the cones lie on opposite sides of the plane of intersection, is considered, and associated discontinuity effects quantified for arbitrary loading and geometric parameters of the intersecting cones.

Towards robust knockdown factors for the design of conical shells under axial compression

International Journal of Mechanical Sciences, 2018
Thin-walled conical shells are used as adapters between cylindrical shells of different diameters in launch-vehicle systems. Conical shells carry heavy payloads and are consequently subjected to axial compression.

The caseinase activity of some vermivorous cone shell venoms

Toxicon, 1971
Abstract Venom extracted from anterior regions of the venom ducts of Conus arenatus, Conus lividus, and Conus quercinus displayed significant proteolytic activity towards casein with optimal activities between pH 9 and 10. In contrast no caseinase activity was displayed by venoms extracted from the posterior regions of the venom ducts.

Inextensional Vibrations of a Sphere-Cone Shell Combination

The Journal of the Acoustical Society of America, 1959
The Rayleigh inextensional theory for thin shells is employed to predict the natural frequencies of a sphere-cone combination. For a particular case, the calculated and measured natural frequencies of shells of nonuniform thickness are determined. In comparing the experimental values of the lowest five “bell” frequencies with the predicted theoretical ...

The foregut glands of vermivorous cone shells

Australian Journal of Zoology, 1971
Salivary, snout, and secondary salivary glands are recorded in the foregut region of Conus Javidus, C. lividus, C. litteratus, C. miles, C. vexillum, and C. virgo. C. imperialis has a salivary gland only. The histology and histochemistry of these glands in C. Javidus and C, lividus is investigated.

The distribution of organic cores, cones, cone junctions and pores in the egg shells of wild birds

Journal of Zoology, 1978
Egg 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

1989
The 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, 1997
A 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.

Stability Analysis of Plate-Cone Reticulated Shell

Applied Mechanics and Materials, 2011
This 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, 1987
Six 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.
