NASAL PACKING: The Rubber Pneumatic Pack

Archives of Otolaryngology - Head and Neck Surgery, 1951
An improved model of the rubber pneumatic nasal pack previously described1has been developed after 15 yr. of experience with nasal packing methods. The earlier model of the nasal pack (Fig. 1) was unavailable during World War II owing to the rubber shortage, and the present change was felt advisable when production was resumed.

Randomly Packed and Solidly Packed Spheres

Canadian Journal of Mathematics, 1964
In the classical packing problem unit spheres are placed without overlapping in D-dimensional space. When D = 2, the densest packing is a familiar regular arrangement of circles, each circle touching six others. In this packing, circles cover a fraction π/√12 = 0.9069 . . . of the area of the plane.

Ahead of the pack

Nature, 2009
The Boston-area biotechnology cluster is one of the most successful on the planet. But competition is growing from other states and countries. Heidi Ledford reports on what the region is doing to maintain its edge.

The Packing Theorem and Packing Measure

Mathematische Nachrichten, 1990
AbstractFor a VITALI class of a metric space (X, d) a packing measure is introduced following the ideas of [7]. The Packing Theorem of VITALI is a powerful mean to derive density results for measures [1, 2, 3]. Conversely, the notion of packing measure allows us to give sufficient conditions for a measure that the packing theorem of VITALI hods.

Sphere packings and packings of ellipsoids

2006
Homogeneous and heterogeneous sphere packings and packings of circles together with their densities are defined, and a classification into types of sphere packings and types of circle packings is introduced. Some properties of the 11 types of homogeneous circle packings are described in a table.

Packings in enneads [PDF]

Australas. J Comb., 1992
In the notation of the author's paper reviewed above, let \(k=9\), \(v\leq 73\) (the reason for the inequality is that if there is a projective geometry with \(k\) points on each line, then it provides a perfect packing of all pairs selected from the \(v=k^ 2-k+1\) points in exactly \(b=k^ 2-k+1\) blocks). The author considers packings for all possible

638 Abscesses. to Pack or Not to Pack?

British Journal of Surgery
Abstract Aim Recent studies have suggested packing post incision and drainage (I&D) of abscess results in increased pain with minimal impact on recurrence or fistula formation. The aim of this study is to assess the management of abscesses post I&D and determine short-term outcomes.

Packing a Trunk

2003
We report on a project with a German car manufacturer. The task is to compute (approximate) solutions to a specific large-scale packing problem. Given a polyhedral model of a car trunk, the aim is to pack as many identical boxes of size 4 × 2 × 1 units as possible into the interior of the trunk.
