Book Review of Raising Less Corn, More Hell: The Case for the Independent Farm and Against Industrial Food by George Pyle

Raising Less Corn, More Hell may sound like a rallying cry for the nation's heartland farmers, but this well-written series of essays by George Pyle is meant for those who eat corn. Or rather, for those of us who eat the livestock fed on corn in confined animal feeding operations, then wash down those meals with drinks high in high-fructose corn syrups. Pyle, an editorial writer from Kansas now living in Utah, brings his journalist's skills to bear on what our industrial food system has brought us. It's not appetizing as he makes his case against a corporate-controlled system that doesn't have to be this way.

Association and Structure of Thermosensitive Comblike Block Copolymers in Aqueous Solutions

The structures and association properties of thermosensitive block copolymers of poly(methoxyoligo( ethylene glycol) norbornenyl esters) in D2O were investigated by small angle neutron scattering (SANS). Each block is a comblike polymer with a polynorbornene (PNB) backbone and oligo ethylene glycol (OEG) side chains (one side chain per NB repeat unit). The chemical formula of the block copolymer is (OEG3NB) 79- (OEG6.6NB) 67, where subscripts represent the degree of polymerization (DP) of OEG and NB in each block. The polymer concentration was fixed at 2.0 wt % and the structural changes were investigated over a temperature range between 25 and 68°C. It was found that at room temperature polymers associate to form micelles with a spherical core formed by the block (OEG3NB) 79 and corona formed by the block (OEG6.6NB) 67 and that the shape of the polymer in the corona could be described by the form factor of rigid cylinders. At elevated temperatures, the aggregation number increased and the micelles became more compact. At temperatures around the cloud point temperature (CPT) T ) 60 °C a correlation peak started to appear and became pronounced at 68 °C due to the formation of a partially ordered structure with a correlation length ∼349 Å.
