(1) Anterior lenticonus is a rare condition, in which there is a conical or spherical protrusion of the anterior surface into the anterior chamber.
(2) Conical root shapes without special provision of retention are not suitable.
(3) However, in conical cells the new oral apparatus and fission line form well posterior to the cell equator, so the opisthes are invariably smaller than proters.
(4) Their use is indicated in large or total defects to restore the natural anatomical conical shape of the eardrum, particularly in congenital atresia.
(5) That of the small conical filiform papillae is to take food efficiently into the oral cavity.
(6) Following enlargement of sporozoite buds the apical ends of the buds became conical in longitudinal sections with the newly formed apical rings at their truncated apices and then, newly formed dense inner membranes and subpellicular microtubules gradually extended backwards and finally enclosed the sporozoites.
(7) 1) In polishing the axial surface of the inner crown of the conic telescope crown system, the milling machine with a polishing disk facilitated specular finishing without causing undercutting in the region from the occlusal surface to the dental cervix.
(8) The study of the effect of dimensions and local organization of net tissue on its electrical properties can be reduced to the problem of investigating electrical properties of conic fibre at different laws of its expansion.
(9) The conical shape of the occlusion device is well suited for the anatomic structure of the ductus.
(10) Considering both the present data and previous findings, Palaeognath birds appear to be a peculiar and monophyletic group, characterized by: 1), a conical acrosome surrounding the nucleus; 2), a fibrous sheath around most of the axoneme; and 3), an elongated distal centriole occupying the entire midpiece.
(11) Scanning electron micrographs showed them to be smooth-surfaced conical to tubular extensions arising from putative photoreceptor inner segments.
(12) The sperm consists of a conical head and 100 flagella.
(13) Subsequent analysis of a mathematically describable conical geometry demonstrates the need for improved compensator design.
(14) Many of the lanceolate receptors contained multiple unmyelinated axons, and the usually highly ordered circular innervation of the inner conical body was markedly abnormal.
(15) For osteotomy conic cutters were used (diameter of base 2.1 mm and 5 mm) and a drill (3000 rotations per minute) from the small instrumentarium of SYNTHES Co.
(16) The concept of stimulation threshold is generalized to three dimensions, and an excitability surface is constructed, which for cardiac muscle is approximately conical in shape.
(17) The results showed that the resisting areas are larger in pyramidal than in conical preparations.
(18) The hooks (105 by 24 nm) each displayed a conical protrusion at the proximal end, a concave cavity at the distal end, and helically arranged subunits.
(19) In practice, the pins are introduced in the same way as the previously described procedure, by they must protrude beyond the opposite wall by 6-8 mm; the difference is in the screwing of the "ARUM" nut: first it is screwed as the reduction stress is increased so its conical part penetrates between the fracture edges; then the pin is cut; and the nut is unscrewed so the cut end of the pin will be included in the space of its base.
(20) Eight conical holes drilled in the side of the chamber serve for the insertion of plugs with attachments for perfusion, rapid injection of small amounts of reagents, temperature measurements or for heating the interior of the chamber.
Directrix
Definition:
(n.) A directress.
(n.) A line along which a point in another line moves, or which in any way governs the motion of the point and determines the position of the curve generated by it; the line along which the generatrix moves in generating a surface.
(n.) A straight line so situated with respect to a conic section that the distance of any point of the curve from it has a constant ratio to the distance of the same point from the focus.
