This objection is only overcome when the uptake is so small as to be entirely filled with the ascending current of mingled steam and water.
It is also necessary that this uptakeshould be practically direct, and it should not be composed of frequent enlargements and contractions.
This will readily be seen if we consider the uptake very large when the only head producing circulation in the tubes will be that due to the inclination of each tube taken by itself.
Plants uptake as much potassium as there is available in the soil, and concentrate that potassium in their top growth.
Systemics are large, complex poisonous organic molecules that plants uptake through their roots and that then make the above-ground plant material toxic to predators.
They uptake everything that is in solution, no more, no less while replacing water evaporated from their leaves.
Helpful bacteria exude complex water-soluble organic molecules that plants uptake through their roots and use much like humans need certain vitamins.
There are other bacteria commonly found in soil that uptake ammonia gas and change it to the nitrates that plants and soil life forms need to make other proteins.
Experiments have shown that plant uptake of strontium from soils can be reduced by introduction of calcium in available form into the soil.
The radiobiologist then attempts to interpret the accumulated evidence of uptake of radionuclides.
Biological Uptake In a water environment the minerals necessary to life are held in solution or lie in bottom sediments.
An ingenious plankton trap is placed in a river as part of a long-range study of radionuclide uptake by aquatic organisms.
With tracer techniques, we can see that the root uptake process has poor powers of discrimination.
Illustration: (B) If placed in a band below and beside the seeds, the fertilizer gives high uptake and good root distribution.
With tracers it is possible for the first time to measure chemical uptake in single spores and to follow chemicals through the plant.
Oxygen uptake was increasingly stimulated during the first 20-minute interval by each increase in the amount of glycerol added (Fig.
Comparison of the resulting oxygen uptake with glycerol and with glycerol plus catalase is shown in Figure 11.
The higher levels of glycerol still stimulated oxygen uptakeduring the first 20-minute period after the additions and then slowed the rate of oxygen utilization.
Effect of glycerol-plus-catalase on oxygen uptake of diluted semen.
After a 60-minute preliminary run, in which the rate of oxygen uptake of the sperm in yolk-citrate diluent was determined, the contents of the sidearm were tipped into the main compartment.
The oxygen uptakeof semen that had been frozen and thawed seemed to drop faster than that of unfrozen samples.
Ten samples of semen were subsampled and the oxygen uptake of each was determined at all four levels of glycerol.
Effect of glycerol additions on oxygen uptake of diluted semen at 37 deg.
The addition of glycerol to diluted semen first increased oxygen uptake and then reduced it.
Only, this was to be said of him, that dulness of uptake and disappointment of his teachers were the worst things about this poor boy; he was not so ill-behaved as many were who were made more of.
And, to begin with, let all those attend to Old Honest who are slow in the uptake in the things of religion.
If flame come out of the chimney when the funnel is knocked away, so as to incur the risk of setting the ship on fire, the uptake of the boiler must be covered over with an iron plate, or be sufficiently covered to prevent such injury.
In the center is the engine-room, with the skylight and the uptake from the boilers, and on either side are the cabins and the messrooms.
B shows a child in position for a thyroid uptake study.
Light area in facial region is caused by uptake in bone and extracellular space.
The intensity of the light varied with the counting rate and thus diseased tissues that differed little from normal tissue except in their uptake of an isotope could be discerned.
Illustration: Figure 9 A laboratory technologist preparing dissolved biological materials as part of a study of the uptake of radioactive substances in living organisms.
The biochemical, autoradiographic, and counting techniques that we described previously are all used to determine the uptake of the radioisotopes into the cell’s components.
A design of high rate boilers, in which the uptake does not come into contact with the water, and water tubes are employed, is shown in Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "uptake" in a variety of sentences. We hope that you will now be able to make sentences using this word.
