Sentences with phrase «use simple diffusion»

Instead, they use simple diffusion, so they can even enter cells that have become insulin resistant.

Not exact matches

Although scientists have used a whole array of experimental techniques in the past to investigate the atomic scale details of surface diffusion, they have generally studied the surfaces of traditional three - dimensional materials and have supported the notion that diffusion involves a simple random walk on the surface.

Using a simple first order Fick's law diffusion fit on the emissions and concentrations 1958 - 2002 yieds — with an equilibrium value of 280 ppm — a diffusion constant of 0.98135.

They then estimated the heat flux into the thermocline using a standard (accepted) model, with a thermocline eddy diffusion coefficient of 1.2E - 5 m ^ 2 / s from Ledwell: We estimate s by using this slope along with k = 1.2x10 - 5 m2 / s (the eddy diffusion coefficient in the thermocline [Ledwell et al., 1998]-RRB- So if they are wrong, either their basic model is wrong (which seems unlikely - it is just a simple energy balance model after all), or their choice of eddy diffusion coefficient is wrong.

Incorporating new findings on the radiative forcing of black carbon (BC) aerosols, the magnitude of the climate sensitivity, and the strength of the climate / carbon cycle feedbacks into a simple upwelling diffusion / energy balance model similar to the one that was used in the TAR, we find that the range of projected warming for the 1990 - 2100 period is reduced to 1.1 - 2.8 °C.
