FIGURE 13.2 Beavers colonized only 2 of 47 (4%) experimentally scented potential colony sites (left), but 8 of 49 (16%) unscented control sites (right). Black indicates colonized sites cross-hatched, sites left vacant. Fulton County Experiment. (FromMuller-Schwarze 1990.)... 

Fig. 1. The GP Ib-IX-V complex. The complex consists of seven transmembrane polypeptides denoted GP Iba (mol wt 145,000), GP IbP (mol wt 24,000), GPIX (mol wt 17,000) and GP V (mol wt 82,000), in a stoichiometry of 2 2 2 1. The hatched region represents the plasma membrane. The area above the hatched region represents the extracellular space that below represents the cytoplasm. The complex is a major attachment site between the plasma membrane and the cytoskeleton. Two molecules associated with the cytoplasmic domain are depicted a 14-3-3 dimer, which may mediate intracellular signaling, and actin-binding protein, which connects the complex to the cortical cytoskeleton and fixes its position and influences its function.

FIGURE 9.5. The potential surface for the 0"C = 0— 0-C-0" step in amide hydrolysis in solution, where the surface is given in terms of the angle 0 and the distance b. The heavy contour lines are spaced by fi (at room temperature) and can be used conveniently in estimating entropic effects. The figure also shows the regions (cross hatched) where the potential is less than for the corresponding reaction in the active site of subtilisin. 

Figure 5.5. Summarized 6 C data Tor browsers and grazers, expressed as dark shaded and cross-hatched boxes, respectively, incorporating means and standard deviations, from the three groups of sites plotted against time (a) Die Kelders and Swartkrans, (b) Klasies and Makapansgat, and (c) Border Cave. Typical matrix values are shown as light shaded rectangles.

Upper panel The hydropathy profile of the entire 69 kD precursor protein is shown. The abscissa is amino acid residues and the ordinate, positive values indicate hydrophilic. The black and hatched rectangles at the bottom of the figure denote the calculated signal sequence and amino-terminal propeptide domains, respectively. The mature and carboxyl-terminal domains are labeled. N-linked core glycosylation consensus sites are depicted by branched structures.

Hatched bars, putative amphipathic helices (numbers at tops and bottoms of bars refer to positions of amino acids). CHO, possible site of N-linked glycosylation. Solid bars, regions of the porcine renal Na /H exchanger used for immunolocalization in LLC-PK cells.

Figure 5. Cartoon models of the reaction of methanol with oxygen on Cu(llO). 1 A methanol molecule arrives from the gas phase onto the surface with islands of p(2xl) CuO (the open circles represent oxygen, cross-hatched are Cu). 2,3 Methanol diffuses on the surface in a weakly bound molecular state and reacts with a terminal oxygen atom, which deprotonates the molecule in 4 to form a terminal hydroxy group and a methoxy group. Another molecule can react with this to produce water, which desorbs (5-7). Panel 8 shows decomposition of the methoxy to produce a hydrogen atom (small filled circle) and formaldehyde (large filled circle), which desorbs in panel 9. The active site lost in panel 6 is proposed to be regenerated by the diffusion of the terminal Cu atom away from the island in panel 7.

Fig. 41. Crystal structure of the f-imidazolium dihydrate associate 1,) (O atoms dotted, N atoms hatched) showing intra-associate H-bonds (broken lines) and the resulting coinciding atomic sites from the fitting experiment with SGPA (bold dots). A position marked indicates the translated OlO from the anion. An expected atomic position of the Or atom of Seri 95 (not considered as a part of the modelling experiment) is indicated merely to show the resulting would-be position executing the same transformation as for the seven fitted atoms. Only relevant H atoms are shown...

Fig. 23 The bonds that constitute crystalline domains must lie nearly parallel to the jy-axis with an angle 6 of less than 20°. Furthermore, the bonds must have at least three neighbors that satisfy 0.7a < Jr + r < 1.3a and ry < r0/2. Note that the crystalline stems deep inside the crystal (black spheres) have six neighbors, while those on the free sin-faces (hatched spheres) have four neighbors. The stems at the half-crystal site, or at the kink site, (white sphere) have three neighbors. Stems attached on the free surface, and those floating in the melt phase have less than three neighbors...

Chemical signals associated with egg sites are probably widespread in insects, but we know much less about them than about sex attractants. These egg-site signals guide one of a female insect s critical decisions, her choice of appropriate places to lay her eggs. If larvae are to have a chance to survive, they must hatch into a suitable setting where proper nourishment is available. Not all larvae are as particular about their food as those of French truffle flies (,Suillia humilis and related species), which feed selectively on the... 

A nonchemical factor also influences a sand fly s selection of egg sites She prefers narrow cracks and crevices rather than open surfaces. A gravid sand fly, then, is quite exacting about where she deposits her eggs. She avoids exposed areas and looks for a site that already contains eggs of her own species along with simple organic nutrients. Her concerns seem well placed, for these characteristics promise safety, protection from the elements, and food for newly hatched larvae. 

Female Lomamyia lay their eggs clustered on little stalks they attach to termite-infested wood. How they choose egg sites is unexplored. When the eggs hatch, the larvae crawl down the stalk and into the wood to search out termite nests, where they make their home. The resident termites seem to accept them, although the larvae are cautious when termites are nearby. Do the larvae smell like termites Despite the apparent peace between them, the larvae live by preying upon the termites in an odd manner. 

Upon completion of site characterization activities, the team should prepare to exit the site. At this stage, the team should make sure that they have documented their findings, collected all equipment and samples, and resecured the site (e.g., locked doors, hatches, and gates). If the site is considered to be a potentially hazardous site or crime scene, there may be additional steps involved in exiting the site.

The data were recorded at 4.2 K in a magnetic field of 0.05 T A, or 8 T B applied parallel to the y-rays. Theoretical simulations for the individual iron sites of the [2Fe]H cluster dotted-and-dashed lines, component A dashed lines, component B) and of the [4Fe-4S]e cluster (dotted-and-dashed lines, component C dashed lines, component D) are shown above the experimental data. Solid lines, superpositions of these four simulated spectral components.
