Head to Head

Wildlife Society Bulletin, 2005
Miller et al. (2005) assert that the estimate of White et al. (2005) of 1.94% of eastern Colorado being occupied by black-tailed prairie dogs (Cynomys ludovicianus) was biased high. The subsequent surveys conducted by Miller et al. (2005) do not provide a valid bias correction for the estimate of White et al.

A Head-Within-A-Head

CLINICAL NUCLEAR MEDICINE, 1998
A patient with elevated alkaline phosphatase underwent whole body bone imaging with Tc-99m methylenediphosphonate. Pelvic and lower extremity images showed typical widening and increased density along trabecular and cortical lines typical for Paget's disease. The lateral skull view is remarkable for its head-within-a-head appearance. The posterior view,

Head to head polymers. XVII: Head to head polypropylene

Monatshefte f�r Chemie, 1981
Head to head polypropylene was prepared by catalytic hydrogenation of eithercis-1,4-poly(2,3-dimethylbutadiene) ortrans-1,4-poly(2,3-dimethylbutadiene) with cobalt 2-ethylhexanoate/triethylaluminium as the hydrogenation catalyst in decahydronaphthalene solution.

Head to head polymers. XXV: Properties of head to head polyisobutylene

Polymer Engineering & Science, 1983
AbstractHead‐to‐head polyisobutylene, prepared by the Grignard coupling reaction of 2,2,3,3‐tetramethyl‐1,4‐dibromobutane had molecular weight of 3,000 to 10,000 and was characterized by wide angle x‐ray diffraction, optical microscopy and thermal behavior.

Heading and Head Injuries in Soccer

Sports Medicine, 2001
In the world of sports, soccer is unique because of the purposeful use of the unprotected head for controlling and advancing the ball. This skill obviously places the player at risk of head injury and the game does carry some risk. Head injury can be a result of contact of the head with another head (or other body parts), ground, goal post, other ...

Head‐to‐head polymers 27: Thermal degradation of head‐to‐head polyisobutylene

Polymer Engineering & Science, 1983
AbstractHead‐to‐head polyisobutylene degrades at a maximum rate at 320°C, a temperature about 65°C lower than head‐to‐tail polyisobutylene. Under our conditions, head‐to‐tail (the regular polyisobutylene) degrades (as do many other disubstituted vinyl monomers) to a high yield of the monomer isobutylene.

Polystyrene, Head-to-head

2009
Abstract Preparative Technique H H polystyrene has never been obtained directly from styrene monomer and indirect polymerization techniques have to be used. H–H polystyrene was first synthesized in a four step reaction. It is synthesized by the selective hydrogenation of 1,4-poly(2,3-diphenyl-1,3-butadiene) (PDPB) using potassium/ethanol.
