concretion

There, in three or four fathoms of water, between the reefs of Pacou and Vanou, lay anchors, cannons, pigs of lead and iron, embedded in the limy concretions. The large boat and the whaler belonging to the Astrolabe were sent to this place, and, not without some difficulty, their crews hauled up an anchor weighing 1,800 lbs., a brass gun, some pigs of iron, and two copper swivel-guns.

Troubles and other realities took on themselves a meta-physical impalpability, sinking to mere mental phenomena for serene contemplation, and no longer stood as pressing concretions which chafed body and soul.

We here see at the bottom of the cliffs, beds containing sharks' teeth and sea-shells of extinct species, passing above into an indurated marl, and from that into the red clayey earth of the Pampas, with its calcareous concretions and the bones of terrestrial quadrupeds.

For this discovery, NASA gave an actual reply, explaining via the official Curiosity Twitter account that, "The round 5mm concretion I found (L) contains calcium sulfate, sodium + magnesium, making it different from the hematite-rich 'blueberries.'" 

Dr.Faisal Ghani Siddiqui said gallstone is a concretion that forms in the gallbladder and added that there are three types of gallstone, cholesterol, pigment and mixed composition stone, and the pathogenesis of these involve four steps, including super saturation, gallbladder hypo-motility, nucleation and aggregation, he added.

Also at mac Lyon, the present incorporates the past, as in Two Columns for One Bubble Light, 2007, a biomorphic tent by Ernesto Neto that is a set design for and a continuation of Jean Arp's " Concretion humaine" (Human Concretion) series, 1933-36.

It is positively related to the strength of the concretion, but negatively to the gel time.

Among the topics are Marie Curie's fingerprint: nuclear spelunking in the Chernobyl zone, future megafauna: a historical perspective on the potential for a wilder Anthropocene, establishing new worlds: the lichens of Petersham, noticing microbial worlds: the postmodern synthesis in biology, holobiont by birth: multi-lineage individuals as the concretion of cooperative processes, and synchronies at risk: the intertwined lives of horseshoe crabs and red knot birds.

Adding concretion to the works are Gutierrez's trademark relief technique, which sets off the images from their surface, giving them a grainy texture and a certain dynamism that contribute further to the stained-glass effect, adding luminosity and buoyancy.

We also find that many of these preserved structures coexisted in a small closed concretion. The subpolygonal honeycomb coccoid structures in the Xiamaling Formation show some wall-to-wall contact, with four or even more coccoids as neighbors (Figures 5(c)-5(e)).
