But some message, some brief scrawl from God, a legible graffito on that invitingly blank and friable surface.
At the end of the experiment, the solid sample exhibited three zones which were accurately characterized: (i) a highly porous and friable surface layer, (ii) a less porous intermediate zone in which several precipitation and dissolution fronts occurred, and (iii) the sound core.
Tires and snowplows, in particular, abrade the friable sealcoat surface into fine particles.
Upon sectioning, the cut surface was soft, friable, dark-red, and gelatinous, with a focal, yellowish-gray, solid portion, and hemorrhage.
Less frequent modes of auto-pollination involve (1) the over-secretion of the stigma (Catling, 1990); (2) the movement of the perianth, anther(s), or pollinia (Catling, 1990; Liu et al., 2006); (3) the falling of friable pollinia onto the stigmatic surface(s) (Hagerup, 1952); and (4) the stigmatic functioning of the rostellum (Williamson, 1984; Gamisch et al., 2013).
The surface is fragile and friable, as we say, which means it will only get worse".
A resin that has a quantity larger than 80% of the inorganic phase, is more susceptible to compromise of its mechanical and physical properties, depending on the shape, size, chemical composition and distribution of the particles, making the material friable and giving it a rough surface [9], which potentiates biofilm retention [18, 19, 21] and consequently gingival inflammation [7, 17].
Typical signs were seen such as petechia in mucuous membranes, connective tissue oedema and a large and friable spleen with a dark cut surface reminiscent of blackberry jam.
Too poor to buy proper paints, Schendel worked with cheap combinations cut with talc and brick dust, so that some of the surfaces are now poignantly friable as old plaster.
Due to the friable and lobular nature of the surfaces of both the fibrofatty tissue component and mammary tissue component comprising the freshly excised BCS specimen, any compression to the freshly excised BCS specimen can create artificial crevices, tissue thinning, and reorientation of the overlying fibrofatty tissue and mammary tissue covering the actual tumor surface.
The frosted and etched surfaces of quartz grains in some friable and loosely cemented sandstones seem to indicate the former presence of a carbonate cement that has been leached.
