What's the difference between reptation and thermal?
Reptation
Definition:
(n.) The act of creeping.

(6) The dependence of effective radius on PE and the proximity of 2.PcE to the length of the rod are explained by (a) random orientation of rods at PE values in the region of the plateau, and (b) increasingly preferential end-first orientation (reptation) of the rod as PE decreases below PcE.
(7) The other process, slow, is characterized by a reptation time and a mean orientation factor in good agreement with the biased reptation model without overstretching.

(14) Many of the concepts of polymer science can be applied successfully in a qualitative way to these cements, including the ideas of entanglements and reptation.
(15) The relaxation times of the stretched DNA molecules scale with molecular weight (or contour length) as N2.8, in reasonable agreement with reptation theories.
(16) The process was considered as dsDNA reptation through the phage tail.
(17) The kinetics of reptation process of dsDNA leaving the phage head is analysed theoretically.
(18) We apply the concepts of tube and reptation to the pulsed electrophoresis of DNA, considering both biased reptation and "breathing" modes (internal modes of the chain).
(19) We study the effect of electric field intensity and agarose gel concentration on the anomalous electrophoretic mobility recently predicted by the biased reptation model and experimentally observed for linear DNA fragments electrophoresed in continuous electric fields.
(20) As previously suggested, the transition from the linear to the concave segment corresponds to that from the randomly oriented DNA to the anisotropically stretched, "reptating" DNA.
Thermal
Definition:
(a.) Of or pertaining to heat; warm; hot; as, the thermal unit; thermal waters.
Example Sentences:
(1) Between 25 and 40 degrees C, the thermal dependencies of VR and f were approximately constant (Q10's of 1.31 and 1.36 got VR and f, respectively).
(2) Thermal stabilities (Tm's) of the hybrid between the 2'-O-methyl ribooligomer and the complementary ribooligomer and of the related hybrids are compared.
(3) Studies were conducted to evaluate the effects of acute (24 h) thermal stress on anterior pituitary function in hens.
(4) Average temperature changes observed were less than 1 degree C. The present study demonstrates that the electrically evoked response in mammalian brain can be altered by ultrasound in a non-thermal, non-cavitational mode, and that such effects are potentially reversible.
(5) Fibroblasts from two such TSD patients had Hex A activity comprising 16% of total Hex when measured by thermal fractionation and quantitation with 4-methylumbelliferyl-beta-D-N-acetylglucosamine (4MUG).
(6) The slope of the thermal inactivation curve of enterotoxin A in beef bouillon (initial pH 6.2) was found to be approximately 27.8 C (50 F) with three different concentrations of toxin.
(7) Considerable glucose 6-phosphatase activity survived 240min of treatment with phospholipase C at 5 degrees C, but in the absence of substrate or at physiological glucose 6-phosphate concentrations the delipidated enzyme was completely inactivated within 10min at 37 degrees C. However, 80mM-glucose 6-phosphate stabilized it and phospholipid dispersions substantially restored thermal stability.
(8) Both enzymes are capable of catalyzing the refolding of thermally denatured type III collagen.
(9) Effects of fixation with glutaraldehyde (GA), glutaraldehyde-osmium tetroxide (GA-OsO(4)), and osmium tetroxide (OsO(4)) on ion and ATP content, cell volume, vital dye staining, and stability to mechanical and thermal stress were studied in Ehrlich ascites tumor cells (EATC).
(10) The physical parameters measured are the intensity attenuation and absorption coefficients, the ultrasonic speed, the thermal conductivity, specific-heat capacity and the mass density.
(11) Thus, MT and MB evoke distinct forms of thermal dysfunction from the androgen receptor in ligand-sensitive androgen resistance.
(12) The procedure to accomplish this end utilizes the measured thermal pain threshold, surface temperature, exposure time, and incident energy on a standardized skin site (volar surface of the forearm) to obtain conductivity values.
(13) The subjects were exposed to manganese, iron , chromium compounds, thermal radiation, high temperature and noise.

The organism's thermal and physiological characteristics are compared to those of Bacillus stearothermophilus, Methanobacterium thermoautotrophicum, Sulfolobus acidocalderius, Thermus aquaticus, Thermus flavus, as well as Thiobacillus denitrificans, the latter being the only other facultatively anaerobic chemolithotroph which has been isolated and described.
