The time variation of the Tg thickness gradient was compared to the time variation of the temperature gradient
. The fibers are at a rubbery state during a limited period that depends on the position within the sample thickness: the period is shorter near the side where water vapor is evacuated, due to lower water content at this location within the thickness.
capillary electrophoresis (TGCE) is a high-throughput method for detection of DNA variation with a high sensitivity, rapid separation time, and a small DNA concentration (~200 pg/ [micro]L) requirement (27).
focusing has been demonstrated for a variety of different analytes including fluorescent dyes, amino acids, proteins, DNA, and colloidal particles.
Current research efforts focus on understanding how Northern Hemisphere extreme cyclones may change under the competing influences of the projected increase in the upper level temperature gradient
and substantial decrease in the near surface temperature gradient
under global warming.-Edmund Chang (Stony Brook University), "Projected Significant Increase in the Number of Extreme Extratropical Cyclones in the Southern Hemisphere," in a forthcoming issue of Journal of Climate.
In summary, Figure 5 indicates that a long shaft can be correctly modeled by CONTAM97R if the temperature gradient
in the shaft can be well resolved, e.g., by using the FZS and dividing the shaft into an enough number of subzones.
We begin with some initial guess value of [[eta].sub.[infinity]] and solve (9) subject to the boundary conditions (10) with some particular set of parameters to obtain the surface velocity f'(0) and the temperature gradient
The average temperature gradient
can be obtained by applying a linear least-squares fitting to the temperatures of these slabs between the thermal reservoirs.
We find out that different diffusivity ratios [alpha] do not affect on final values of temperature gradient
in the phases, but according to the Fig.
The copper wings connect to the heat sink holder when inserted, and lower the temperature gradient
close to the fiber, improving power resistance of the assembly.
The researchers also found these south-flowing waters act to transport heat along with them, cooling the ocean and in effect increasing the temperature gradient
between the land and sea.
The slab track system was heated and/or cooled to produce a temperature gradient
consistent with characteristics of a real track system.
