SEA and strategy formation theories: From three Ps to five Ps

From PS{splines to NURPS

Biotech, the environment and the three Ps.

To answer your first question: the three Ps in the title stand for people, profit and preservation. I must admit that when I was asked to participate in a discussion on ‘The Biotechnology Industry and the Environment’ at the recent BioVision conference in Lyon, France, I did not immediately think of the three Ps. At a factual level, the biotechnology industry seems to be environmentally friendl...

Enhanced Ps-Ps interactions due to quantum confinement.

Slow positrons implanted into a porous silica film may efficiently form positronium (Ps) atoms that diffuse through a network of interconnected pores. At high Ps densities, the long lifetime of ortho-positronium atoms is reduced due to Ps-Ps spin dependent interactions at a rate that implies an effective free-space scattering cross section, σ(e) = (3.4 ± 0.5) × 10(-14) cm(-2), at least 25 times...

The 'three Ps' of cancer survivorship care

What is the definition of ‘cancer survivor’ and what is ‘survivorship care’? With the growing numbers of individuals surviving long term and disease free after a cancer diagnosis, a group of individuals in the US came together in 1986 to establish the National Coalition for Cancer Survivorship (NCCS; http://www.canceradvocacy.org), and defined cancer survivors as individuals with cancer from th...

Using Three-dimensional Polystyrene (PS) ScaffoldsTM to Produce Tumor Spheroids

In vitro tumor spheroids are generated using scaffold-free technologies, e.g. hanging drop, agar gel sandwich, and low adhesive surfaces, etc, for drug screening applications. Some of these platforms are currently adapting towards reducing spheroid time formation and increasing highthroughput workflow. Here, we show the use of 3-dimensional (3D) polymer scaffolds to generate multicellular spher...
