What's the difference between acicular and aciculate?
Acicular
Definition:
(a.) Needle-shaped; slender like a needle or bristle, as some leaves or crystals; also, having sharp points like needless.
Example Sentences:
(1) The acicular alpha structure has been shown to exhibit the best fatigue properties for Ti-6A1-4V alloy in the notched condition.
(2) It was observed that the larger the cast volume and the higher the mold temperature, the thicker became each layer and the coarser became the acicular grains.
(3) The essence of double-nucleus phenomenon and morphogenesis of acicular ichthyosis are disputable at present.
(4) The influence of particle size on hemolysis and cytotoxicity was observed with acicular grunerite.
(5) The heat treatments examined produced alternate microstructures to the lamellar structure and some approached the totally transformed acicular alpha structure.
(6) The interfacial zone was composed of four layers: the outermost reaction or casting burn layer, the second layer of an O-and Al-stabilized alpha case, the third layer in which Si, P, O, and C were inhomogeneously concentrated, and the fourth layer which consisted of acicular or plate-like crystals.
(7) It is suggested that the double-nucleus phenomenon in the epidermis in type Curth-Macklin [correction of Kurt-McLean] acicular ichthyosis is due to cytokinesis-controlling gene mutation.
(8) The noncoated coarse and fine acicular specimens displayed an approximate 25% increase over the noncoated lamellar specimens.
(9) The porous coated coarse and fine acicular specimens showed an approximate 15% improvement over the porous coated lamellar specimens.
(10) A mixture of CF4 and O2 quantitatively remove the acicular nitride phase without any evidence of attack on either the glass or carbide.
(11) The characteristic features of H. taichui cercaria are the presence of two sets--one set of lateral and other dorsoventral cuadal finfolds, 15 acicular spines in three alternating rows and seven pairs of lobed penetration glands arranged in two longitudinal rows.
(12) The giant lysosomes characteristic of cyclodextrin nephrosis are notable because of the prominent acicular microcrystals embedded in the lysosomal matrix.
(13) In PICG, cholesterol esters are released from degenerating macrophages and, as organization occurs, the cholesterol is deposited in the form of acicular clefts within the interstitium.
(14) All four drugs, Puromycin and its aminonucleoside, Cordycepin and Nucleocidin, induced electron-lucent cytoplasmic clefts in the cytoplasm, which were generally acicular or spindle-shaped, with long axes lying in any direction.
(15) H. pumilio cercaria is characterized by the presence of two sets of caudal finfolds, 15 acicular spines in three alternating rows and seven pairs of voluminous unicellular penetration glands.
(16) Scattered foci of cholesterol pneumonia, composed of acicular crystals with an associated foamy lipid material and type II alveolar epithelial cell hyperplasia, were present.
(17) Aggregates of acicular clefts and crystals were present in bile canaliculi, bile ducts, Kupffer cells, hepatocytes and in kidney tubules.
(18) Radially oriented acicular crystalline aggregates could be induced by incubating heparinised blood with bacterial endotoxins.
(19) Electron microscopy of "normal" lung tissue from four heavy cigarette smokers showed acicular crystal clefts thought to represent cholesterol in the cytoplasm of virtually every type II pneumocyte.
(20) Acicular and rhomboidal clefts, some with a characteristic notch, were observed mainly in extracellular locations, although they were also associated with dying fibroblasts.
Aciculate
Definition:
(a.) Alt. of Aciculated
Example Sentences:
(1) Plasmogamy between compatible strains is followed by the development of very large elongate asci bearing vestiges of the zygotes and the formation in each ascus of two unusually large aciculate ascospores similar to those formed by members of the genus Metschnikowia.
