The hypothalamus is a very small cone-shaped structure that lies beneath the thalamus. Despite its small size, it is one of the most important structures in the human brain. The hypothalamus ends in the pituitary stalk (also called the infundibular stalk) which connects it to the pituitary gland.The 1883 eruption resulted in the removal of two of the three volcanic cones which made up Krakatoa Island and the area between the three remaining remnant islands was filled by the sea to a depth of 250 m. The eruptions began in May of 1883 with small explosions and built up in activity. ... Structure and composition of the Earth. Radioactive ...Squirrels are considered to be ineffective seed dispersers, and the cones of pines consumed by squirrels have stronger defense structures where squirrels are in large number, with thicker scales and seed coats, diminished seed numbers, and decreased mass of the nutritious seed kernel (Siepielski & Benkman, 2007 ).Light Cones. That the speed of light is a constant is one of the most important facts about space and time in special relativity. That fact gets expressed geometrically in spacetime geometry through the existence of light cones, or, as it is sometimes said, the "light cone structure" of spacetime.cone structure on C. If some of the cone angles is <π, then the subset E⊆ (0,π)q of multiangles of Eu-clidean cone structures is a smooth, properly embedded hypersurface that splits (0,π)q into 2 connected components Sand H, corresponding to multiangles of spherical and hyperbolic cone structures respectively.A Note on Cone-in-Cone Structure - Volume 11 Issue 49. page 24 note 2 Geol.

A local example of non-flat perturbations of the global model of flat Lagrangian cone structure ...The male and female gametophyte structures are present on separate male and female cones in gymnosperms, whereas in angiosperms, they are a part of the flower. Finally, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.In gymnosperms, male cones have structures that create pollen. Female cones have structures that create eggs. Later, the female cones develop seeds on the scale structures of the cones. Cone-bearing gymnosperms are designed to be pollinated by the wind, with male cones frequently arranged on branches above the females.Cone-in-cone is an enigmatic structure. Similar to many fibrous calcite veins, cone-in-cone is generally formed of calcite and present in bedding-parallel vein-like accumulations within fine-grained rocks.
