Partial Splenic Embolization with Y-Shaped Silicone Particles

Acta Radiologica, 1994
We have developed an embolizing material consisting of Y-shaped silicone particles for partial splenic embolization. Wide spaces for blood flow are left around the particles when these are lodged in arterial branches. We embolized one kidney in each of 3 dogs with the particles and observed a slowly induced occlusion of renal arterial branches during ...

Synthesis and optical studies of Y-shaped imidazole derivatives

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2019
A novel series Y-shaped π-expanded imidazole based chromophores was designed and synthesized. The series contains thirteen 2-aryl-4,5-bis[2-(aryl)vinyl)]-1H-imidazoles (6a-6m), which were characterized by spectroscopic analysis. The structures of compounds 6d and 6j were also confirmed by X-ray crystallographic analysis.

Y-Shaped Ovum of a Demodicid from Clethrionomys gapperi

The Journal of Parasitology, 1968
A description with measurements of this unique ovum is provided, egg-laying process detailed, and locus in the host described. It is suggested that the anterior prongs represent a "hold- fast" adaptive mechanism which maintains the ovum in the Meibomian canal against the flow of Meibomian secretion.

Nanofibrillar Structures in Thermotropic Polyesters with Y-Shaped Mesogenes

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Liquid crystalline main chain polyesters containing Y-shaped mesogenes with flexible lateral substituents of different length have been investigated by X-ray diffraction and DSC experiments. The X-ray patterns of the polymers with lateral substituents longer as the methoxy group show beside the reflections at the wide angle range also small angle ...

Oscillatory flow in a y-shaped bifurcation.

Acta physiologica latino americana, 1977
Fluid particle trajectories in oscillatory flow in Y-branched tubes of equal radii were quantitatively analyzed for an oscillatory number square root 2pi/Tv.ro of the order of unity and qualitatively for an oscillatory number of the order of 25. Radial distribution of trajectories and secondary motions are described.

Increasing the Flow Output by Y-Shaped Microvascular Anastomosis

Journal of Reconstructive Microsurgery, 2002
In this paper the authors present a new type of microvascular anastomosis to overcome two major inconveniences in microsurgery: "flow discrepancy" and vessel size discrepancy between the donor and the recipient vessels. A Y-shaped anastomosis is an end-to-end anastomosis between three vessels: two small ones on one side and a larger vessel on the ...

Y-Shaped Hole for Film Cooling

Volume 8: Heat Transfer and Thermal Engineering; Mechanics of Solids, Structures and Fluids
Abstract Adiabatic effectiveness (η) of film cooling is strongly affected by the geometry of the film-cooling hole. This study presents a new shaped-hole design, referred to as the Y-shaped hole, that seeks to increase η by splitting the cooling flow into three streams for increased lateral spreading and by decreasing the flow’s cross-

The Y‐Shaped Pattern of Alopecia Reduction and Its Variations

The Journal of Dermatologic Surgery and Oncology, 1984
Abstract The Y‐shaped alopecia reduction is used less frequently than indicated. This article outlines the advantages of this pattern, describes the technique of excision in detail, discusses the many variations possible, and advocates greater utilization of this procedure.
