1. Spatial arrangement and density effects on an annual cotton/cowpea/maize intercrop. I. Agronomic efficiency.
Field experiments were conducted in Tucson, Arizona, to examine the effects of spatial arrangement and density on the agronomic efficiency of an annual cotton/cowpea/maize intercrop. The major results were: (1) the Land Equivalent Ratio (LER) for yield was higher in the spatial arrangement of single rows of cowpea and maize between single rows of cotton, (2)

2. Differential Response Patterns in the SI Barrel and Septal Compartments During Mechanical Whisker Stimulation
A growing body of evidence suggests that the barrel and septal regions in layer IV of rat primary somatosensory (SI) cortex may represent separate processing channels. To assess this view, pairs of barrel and septal neurons were recorded simultaneously in the anesthetized rat while a 4 × 4 array of 16 whiskers was mechanically stimulated at 4, 8, 12, and 16

3. Structural arrangement of polymers within the wall of Streptococcus faecalis.
The structure of the cell wall of Streptococcus faecalis was studied in thin sections and freeze fractures of whole cells and partially purified wall fractions. Also, the structures of wall preparations treated with hot trichloroacetic acid to remove non-peptidoglycan wall polymers were compared with wall preparations that possess a full complement of access

4. Treponema pallidum rare outer membrane proteins: analysis of mobility by freeze-fracture electron microscopy.
Freeze-fracture and deep-etch electron microscopy were used to investigate the molecular architecture of the Treponema pallidum outer membrane (OM). Freeze-fracture electron microscopy of treponemes freshly harvested from rabbit testes revealed that the intramembranous particles (IMPs) in both the concave and convex OM leaflets were distributed into alternat

5. The pattern of histogenesis and growth of tooth plates in larval stages of extant lungfish.
Comparison of new data obtained in this study on Protopterus aethiopicus with that published on Protopterus aethiopicus and Neoceratodus forsteri has confirmed the suggestion that the pattern of histogenesis of tooth plates in the early larval stages is very similar in the two genera. These similarities are more apparent both when a common terminology is ado
