The thickness at which such an accumulation collects and progresses upstream depends on the velocity of the flow (V) and is given implicitly in the formula in which g is acceleration of gravity, ρ and ρi are the densities of water and ice, respectively, h is the thickness of the accumulating ice, and H is the depth of flow just upstream of the ice cover.
As the ice cover accumulates and progresses upstream, it both adds resistance to the flow and displaces a certain volume of water.
Eventually these pans may enlarge and freeze together to form larger floes, or they may gather at the leading edge of an ice cover and form a layer of accumulating ice that progresses upstream.
And the further I climb the more adamant it gets in its opposition, as if a whole North Atlantic weather front has come bursting through the collapsed dam of Bellcrag Flow, pouring through the gap, so that any progress is progress upstream, against the flood, into the rapids, with boulders and logs of hard air piling into me and knocking me sideways.
Shreve broke the Fulton-Livingston monopoly of steam navigation on the river, but his title as the father of Mississippi navigation stems more from his adaptations of steamboat design to fit the shallow waters of the river; he used a high-pressure steam engine (to make progress upstream), hoisted it high up above the water line, and mounted it on a hull that was as shallow as that of a barge.
In addition, the schedule according to which the total dose is delivered is also important, and this is mainly related to the fact that red cell destruction in AHA associated with G6PD deficiency is an orderly function of red cell age: the oldest red cells with the least G6PD are the first to haemolyse, and the haemolytic process progresses upstream toward cells with more and more G6PD activity.
As a result it is difficult to trace progress in upstream work and the extent to which UNICEF is achieving what it sets out to do. 6. Managing the balance between upstream and downstream: in the Zimbabwean context UNICEF has maintained its relevance and effectiveness by continuing with downstream implementation work in conjunction with its upstream work.
Surgical and catheter-based interventions on pulmonary veins are associated with pulmonary vein stenosis (PVS), which can progress diffusely through the "upstream" pulmonary veins.
The simulation demonstrates that the flow in a pipe can progress backward from downstream to upstream when the upstream water head reaches a critical value.
Moreover, a relatively short DNA region, lost in up2Δ and located immediately upstream of the URA2 initiator, impairs URA2 transcription by preventing RNA polymerase II from progressing towards the URA2 open reading frame.
