Head to toe, in the head [PDF]
Proceedings of the National Academy of Sciences, 2015 Sometime about 250,000 y ago, primates started talking to each other (1). Before that time facial expressions and body language were the main modes of communication among primates. Even today in the presence of our sophisticated language system, face and body gestures play a major role in human communication.

The head-to-head photodimer of indenoindene
IUCrData, 2020 Irradiation of 1-(1-benzocyclobutenylidene)benzocyclobutene gives indenoindene and its head-to-head photodimer nonacyclo[9.7.7.72,10.01,11.02,10.03,8.012,17.019,24.026,31]dotriaconta-3,5,7,12,14,16,19,21,23,26,28,30-dodecaene, C32H24. The molecule is built from four essentially planar indane units attached to an elongated cyclobutane ring.

Head-to-Head Polymers XXXV. Head-to-Head Poly(2-vinylnaphthalene) [PDF]
Polymer Journal, 1986 Head-to-head poly(2-vinylnaphthalene) was prepared in five steps from 2-naphthylacetic acid. The methyl ester was brominated with N-bromosuccinimide and 2(2-naphthyl)2-bromoacetate treated with a copper/zinc couple, which gave dimethyl 2,3-di(2-naphthyl)succinate in moderate yield.

Everything is on the Head [PDF]
Frontiers in Physiology, 2011 During the last 20 years, the field of craniofacial biology has benefited tremendously from the progress made in developmental biology and genomics. The huge quantity of data on numerous genes that are involved in developmental processes has considerably increased our comprehension of the organization and function of molecular networks that are used to

Progress in Polymer Science, 1999 Abstract Pure head to head (H–H) addition polymers, such as H–H polyolefins, H–H acrylates and H–H poly(vinyl halides), have been of interest for the understanding of the structure/properties relationship of addition polymers. These polymer structures have provided challenges of synthesis, characterization and of the measurements of their mechanical ...

A model of chlorophyll a destruction by Calanus spp. and implications for the estimation of ingestion rates using the gut fluorescence method [PDF]
, 1998 Chlorophyll a (chl a) destruction by groups of Calanus spp. with different long-term in situ feeding histories was compared. For copepods that had fed during both pre- and early-bloom conditions, degrees of chl a destruction were relatively constant at ...
