The cone scales of these two species differ in structure during pollination, however; bract scales are larger than ovuliferous scales in Abies while the opposite is the case in Picea (Fig. 1C, ,D). D ).A stereotypical conifer cone, like those of spruces or pines, is a robust structure composed of woody scales that support and protect developing seeds. However, not all conifers have such a cone; around 40 % of living species produce something closer to what one might informally call a ‘berry’ or a ‘drupe’, with white, orange, red or ...Cone-in-cone is a peculiar structure consisting of usually vertical nests of cones, one inside another, that are found either in thin beds or at the edges of large concretions. Some cones are less than an inch tall, and others are as much as 10 inches high. They have a ribbed or scaly appearance.

The pine cone samples for SEM characterization are first immersed in the 2.5% glutaraldehyde for 1 h to fix the structure and then dehydrated with an ascending series of ethanol contents (30, 50, 70, 90, 95 and 100 vol.% twice).An α-cone 3-sphere Si is the quotient of a Euclidean lens of angle α by the rotation about the edge of the lens which identifies the two boundary half-spheres of the lens. A 3-manifold M is said to have Mόbius cone structure with cone Received November 16, 1993.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.Cone-in-cone structures are secondary sedimentary structures that form in association with deeper burial and diagenesis. They consist of concentric inter-bedded cones of calcite or more rarely gypsum, siderite or pyrite.The hierarchical structures, including conical spine, gradient microgrooves, and oriented thorns, enable the fogdrop collection mode to be transformed from dropwise on thorns to filmwise on spine.A novel fiber Bragg grating (FBG) acoustic emission (AE) sensor based on coupling cone structure is proposed in this paper, which is flexible and reusable. The sensor is fabricated by additive manufacturing technology.

The guidance of growth cones is influenced by guidance cues in their environment which generally act on membrane receptors at the growth cone, ultimately influencing intracellular signaling cascades and remodeling the growth cone's cytoskeletal structure. The growth cone is comprised of two regions, the central region and the peripheral region.across. The calcite cones have an analogous columnar structure.

Cone-in-cone is a peculiar structure consisting of usually vertical nests of cones, one inside another, that are found either in thin beds or at the edges of large concretions. Some cones are less than an inch tall, and others are as much as 10 inches high. They have a ribbed or scaly appearance. The structure of apo A3/B3 is a structure of a native vertebrate CNG channel and reveals some striking features that shed light on the question of why the native cone CNG channel has a B3 subunit.
