This is caused , in part , by the effect of thermal diffusion ( caused by the geothermal temperature gradient ) , which cannot be neglected in some cases ; thermal diffusion might be the main phenomenon affecting compositional variation in hydrocarbon reservoirs , especially for near-critical gas / condensate reservoirs ( Ghorayeb et al. 2003 ) . In addition , we discuss the possibility to adapt the mouse ES cells based tests to human ES cells , avoiding inter-species variations in developmental toxicity studies and address related ethical issues . You should not plan your cash flow forecast so tightly that a small variation in actual results can have a significant effect on your ability to keep your business going . The objective of this expeirment was to study possible surface-tension-induced convection , caused by a stepwise compositional variation in a liquid metal contained in both wetting and non-wetting ampoules , with minimum temperature gradients . The letters and power of attorney forms contained non-professional variations in the letterheads , such as commas and ampersands appearing in one document but not repeated on another . Quantitative measurements of H and L ferritin mRNA in various mouse tissues using a ribonuclease protection assay reveals important variations in the L / H ratio , the liver displaying the highest amount of L mRNA . The combined effects of diffusion ( pressure , thermal , and molecular ) and natural convection on compositional variation in multicomponent mixtures in porous media have been investigated for single-phase systems ( Riley and Firoozabadi 1998 ; Ghorayeb and Firoozabadi 2000a ) . Pederson and Lindeloff ( 2003 ) have included thermal diffusion in a 1D vertical model for a single phase at steady state to account for thermal diffusion in compositional variation in hydrocarbon reservoirs . A small variation in forecast and actual tropical cyclone track can result in a particular river system ( and township ) either experiencing a severe flood or little to no flooding .
