Cone structures. These magnetically labeled cells were attracted and captured by hexagonal superparamagnetic cone structures to form cell cluster arrays. As a function of the solid cone size, the number of cells captured by each hexagonal superparamagnetic cone structure was increased from 48 to 126 under a 2000 G out-of-plane magnetic field. The local magnetic ...

Invented and patented by Chuck Henderson, the system uses the unique strength of intersecting cone segments to form sweeping concave and convex continuous curves. The remarkable strength of the multi-conic geometry translates loads into the shearing structural elements of the building material (plywood, ferro-cement, or oct-tet truss framework).

Cinder cones. C inder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.The main parts of the human eye are the cornea, iris, pupil, aqueous humor, lens, vitreous humor, retina, and optic nerve. Light enters the eye by passing through the transparent cornea and aqueous humor. The iris controls the size of the pupil, which is the opening that allows light to enter the lens. Light is focused by the lens and goes ...The future of cone photoreceptor structure/function discovery is bright with emerging models consisting of the cone-rich Nrl−/− mouse line and Nile rat species.

Dirac-cone structures give materials unusual properties and promising prospects in both fundamental and applied research. However, the probability of Dirac cones in 2D systems is rather low. Herein, we have systematically surveyed the known 2D Dirac materials and discussed how Dirac cones emerge and merge in the systems.Seed Cones. The seed cones are terminal or axillary, cone-like or highly reduced, usually fleshy [rarely dry], in some taxa subtended by a stalk ("peduncle") that may fuse with bracts, forming a fleshy "receptacle," ovuliferous scales 1-∞, each bearing a single ovule, in some members a single scale modified as a protective covering around the ovule, the "epimatium".2. Basic structure and signaling of the growth cone. In the growth cone, microtubules (MTs) and various vesicles are concentrated near distal axonal shafts, a region called the central (C-) domain of the growth cone. 8) These vesicles function as plasmalemmal precursors for axonal growth, although the details of their turnover and recycling are not well understood. 9) In addition, some ...The seed-cone structure is similar to that of other conifer families, but in yew, the cone has become reduced to a single small scale and a fleshy red aril that encloses most of the seed.

Growth cones are highly motile structures that explore the extracellular environment, determine the direction of growth, and then guide the extension of the axon in that direction. The primary morphological characteristic of a growth cone is a sheetlike expansion of the growing axon at its tip called a lamellapodium. Cinder cone volcanoes are relatively small, rarely exceeding 1,000 feet tall. Composite volcanoes, also known as stratovolcanoes, are towering structures, often rising more than 10,000 feet.
