The meaning of CONE-IN-CONE is a small-scale geologic structure resembling a set of concentric cones piled one above another developed in sedimentary rocks ...Sorby (1860) also referred to cone-in-cone and noted that the “cones often occur in bands, parallel to the stratification of the rock”. For such reasons, Richardson (1923, page 91) referred to “The Cone-in-Cone Structure in the Beef” (e.g. Fig. 1 C). Both Sorby and Richardson attributed cone-in-cone and beef to a process of crystal growth.cones found in Zamia and other cycads. The fact that the cones are “simple” is important to this interpretation since it means that we can recognize the evolution of the cycad cone from a leaf with ovules rather than a branch with ovules. This distinction is important Cycas maconochiei cones have leaflike sporophylls with Assessing Cone Structure. At least 2 trained and masked independent graders identified cone locations at the ROIs using custom software (Mosaic Analytics, Translational Imaging Innovations, Inc., Hickory, North Carolina, USA) to calculate cone spacing (average nearest neighbor distance in microns) based on the density recovery …Cutting structure: cone and carbide.

Through a friend of the writer's, a small concretionary mass of iron pyrites taken from the " Roaster "A cone only has one flat surface, its circular base. Its other surface is a curved one that extends from the base to the apex. A cone has many important features, starting with a circular base and curved side.Here we examined foveal cone structure in patients with genetically-confirmed BCM, using adaptive optics scanning light ophthalmoscopy (AOSLO). Methods: Twenty-three male patients (aged 6-75 years ...Structure of Eye Cones . These light-sensitive cones are mostly concentrated into a portion of the eye's retina known as the fovea, which enables small details to come into sharp focus in bright light. These powerful little receptors get their name from their cone-like shape.Cone-in-cone structure is considered to be the result of low-nucleation rate precipitation, because unlike micritic carbonate in concretions, they push the clay of the host sediment aside during growth (Füchtbauer, Reference Füchtbauer and Bricker 1971) and thus cannot be used to estimate palaeo-porosity at the time of precipitation.
... The apical angle of cones varies from 15-120°, with the apex often oriented toward the bottom of a layer. In CIC beds, the growth direction is normal to the bedding …As a result, optimizing the boundary structure of the conical section and controlling the distribution pattern of the flow field inside the conical section are vital means to improve the product quality [[13], [14], [15]]. A conventional hydrocyclone contains a straight conical section, the length of which depends on the cone angle.Dr. Conkin first described this structure in 1957 at the Coral Ridge site. He described it as "This double cone-in-cone occurs as two layers of inverted cone-like "golf tees" surrounding an essentially undisturbed solid central mass of impure siderite (FeCO3). These double cone-in-cones occur as elongated lenses embedded in the ...…
