of the crystallization behaviors, such as lamellar thickening and chain folding, especially the underlying thermodynamic and kinetic mechanisms, is a longstanding difficulty. Various experimental and theoretical investigations have been focused on chain folding behaviors in polymer crystals.
A lamellar hole is closely related to a macular hole, but may be distinguished on OCT by the presence of retinal tissue at the base and a characteristic reverse "anvil" or dumbbell shape.

Feederbreakers are used mainly in underground, mechanized mining of materials such as coal and potash. The feederbreaker is traditionally used between the mobile mining machinery and the fixed conveyor systems to reduce product size and smooth the flow on the conveyor belts.
It combines the principle of lamellar settling with an integrated sludge thickener. No need of additional sludge thickening equipment before dewatering. The densification of sludge allows to reduce the volume of extracted sludge and thus limit the water loss.
the lamellar thickening is a thermodynamically irreversible process driven by a driving force arising from the unequal free energies between the fold and lateral surfaces and the nonequi
Sericite A white potashmica, like muscovite in chemical composition and general character but occurring as a secondary mineral, often as a decomposition product of orthoclase. Shale a finegrained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (siltsized particles) of other minerals, especially quartz and calcite.
are discussed in light of isothermal thickening of lamellar crystals. Lastly, almost 200 DSC melting traces of varying molar mass PC samples thermally treated under various conditions were analyzed to calculate crystallinity (Xc), rigid fraction (RF), and rigid amorphous fraction (RAF).
Collenchyma are characterized by the organization and thickness of their cell walls—the wall thickening of angular chollenchyma cells is restricted to the corners of the cell (resulting in a relative "angular" shape), and the thickening of lamellar collenchyma is restricted to the tangential wall.
lamellar thickening and meltrecrystallization do not occur on heating. The â dependence of T m(obs) is related to the "melting kinetics", which we proposed as a .

Experimental animal studies have found that IOP can increase to between 80 and 230 mm Hg during the vacuuming phase and even greater pressures, from 140 to 360 mm Hg, can occur during the lamellar cut. 21 22 Theoretically, a prolonged high IOP would cause retinal vascular occlusion, especially in patients with vasculopathies or diabetes.
Calcium bentonite. Calcium bentonite is a useful adsorbent of ions in solution, as well as fats and oils, being a main active ingredient of fuller's earth, probably one of the earliest industrial cleaning agents.
The anterior lamellar flap (skin and muscle) is dissected inferiorly and off the lateral aspect of the inferior canthal tendonthus separating anterior and posterior lamellae. Next, the conjunctiva is denuded from the inferior canthal tendon using a scraping motion with a 15 blade

The Monroe lamella plate Vertical Clarifier is designed to provide low cost, efficient solids removal from a wide range of waste and process liquids. The inclined plate design allows the total gravity settling area to be as much as ten times more than the actual floor space occupied by the clarifier.
Stroma Figure 210 Under low magnification a chloroplast appears uniformly green. High magnification (a) however, reveals that the chlorophyll is in discrete bodies, called grana, which are surroundedby a clear stroma. Higher magnification (b) reveals that the chlorophyll is arranged in a lamellar fashion.
(Metamorphic Rock > Schist) A strongly foliated crystalline rock, formed by dynamic metamorphism, that can be readily split into thin flakes or slabs due to the well developed parallelism of more than 50 percent of the minerals present, particularly those of the lamellar or .
A bone is a rigid organ that constitutes part of the vertebrate support and protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable come in a variety of shapes and sizes and have a complex internal and external structure.
Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process.. Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually in the order of 1 to 1½%.
The mineral pyroxene is a name applied to a group of silicates that are similar in composition to the hornblende group, but not so often containing soda and pieces show angles of 93° and 87°, thus making nearly square edges, a clear distinction between them and the sharp and obtuse edges of cleavage pieces of hornblende.
Jul 01, 2005· Harlequin ichthyosis (HI) — the most severe form of keratinizing disorders, often lethal in the neonatal period — is characterized by a profound thickening of the keratin skin layer, a dense "armor"like scale that covers the body, and contraction abnormalities of the eyes, ears, and mouth.
