Following Directions with Goofy
This animated video explains why directions are so important.  It shows Goofy a variety of examples in which directions are important and explains what would happen if there weren't directions.  Lots of real life examples of directions are given.  Visual, spoken, and written directions are also described.  Signs are an example of visual directions.  Spoken directions include those from a teacher.  Written directions include those used to help assemble items.  T

Genetically Engineering the Avian Flu
This video segment adapted from NOVA scienceNOW examines the threat of a virus being spread from birds to humans, and then from humans to humans. It details the mechanisms viruses use to infect cells, and explores how mutations in a virus may change its virulence and how it can spread. It also looks at work being done with a re-created flu virus—from the deadly 1918 strain—that may help prevent future flu pandemics. Closed captioning included. Run time 05:08.

Feature clusters for online recognition of graphic units in drawings
Automated recognition of sketch drawings can provide the means for a natural interface between the designer and a design support system. Sketch drawing recognition is knowledge-intensive in the sense that the system must know what to look for in a drawing. In earlier work, we identified 24 different types of representations, termed graphic units. For recognition of graphic units we combine a multi-agent approach and online recognition. Each agent is specialised for one graphic unit. It continuou

Hidden Line Elimination in Projected Grid Surfaces
The hidden line and hidden surface problems are simpler when restricted to special classes of objects. An example is the class of grid surfaces, that is, graphs of bivariate functions represented by their values on a set of grid points. Projected grid surfaces have geometric properties which permit hidden line or hidden surface elimination to be done more easily than in the general case. These properties are discussed in this paper, and an algorithm is given which exploits them

Poly (lactic-co-glycolic acid) (PLGA) porous scaffold for tissue engineering.
The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. Average Pore Size 100-300 micrometre+D7, porosity estimated at 65%.

Superspace: One Thousand and One Lessons in Supersymmetry
We introduce superfields in chapter 2 for the simpler world of three spacetime dimensions, where superfields are very similar to ordinary fields. We skip the discussion of nonsuperspace topics (background fields, gravity, etc.) which are covered in following chapters, and concentrate on a pedagogical treatment of superspace. We return to four dimensions in chapter 3, where we describe how supersymmetry is represented on superfields, and discuss all general properties of free superfields (and the

Conférence de Bernard Eisenschitz

Cluny Brown (La Folle Ingénue, 1946) est le dernier film terminé par Lubitsch. Il se comparait alors à un danseur qui s’est cassé une jambe et découvre qu’il peut de nouveau danser. Alors, un testament, un post-scriptum ? Et s’il s’agissait plutôt d’une nouvelle chorégraphie, d’un tournant, en phase avec les bouleversements du monde – et du cinéma ?
