Sentences with phrase «transporting higher concentrations»

Not exact matches

«This work demonstrates that mined watersheds contribute disproportionately to summer baseflow through the Appalachian region, so that mine - derived pollutants are at higher concentrations, and are transported farther downstream, during these low flow times of year.

The wind reversal added friction on the ground — which dislodges more dust — and transported it westward over long distances before depositing it in high concentrations on the densely populated east Mediterranean coast.

Because sour taste is the perception of acidic substances, which have a high concentration of protons, Liman predicted that sour taste cells have an ion channel that responds to or transports protons.

Acute insulin stimulation increased glucose transport by 21 % in control cultures precultured at 1 pmol / l insulin, but at higher insulin concentrations we could not detect an effect of insulin on glucose uptake.

They discovered that the phloem unloads through convection, a combination of diffusion, the movement of sugar solute from areas of high concentration to low, and bulk flow, in which both a solute and solution are transported.

Occasionally, upwelling events increase the productivity in these ocean deserts: Oceanic eddies transport deep - water containing high concentrations of nitrate, phosphate and silicate, towards the surface.

Taurine is actually the second most abundant amino acid in the body (the first being glutamine), found in high concentrations in the skeletal muscles and the brain, where it aids the transport of potassium, calcium, sodium and magnesium, which nearly qualifies it as a neurotransmitter.

Once 5 - MTHF has entered the CNS, it can be transported into the neurons by the reduced folate carrier (RFC) or it can diffuse across the blood - brain barrier without a carrier if blood concentrations of folate are high enough.

Human breast tissue and breast milk contain higher concentrations of iodine than the thyroid gland itself, which contains just 30 % of the body's iodine stores.18, 36,370 Breast tissue is rich in the same iodine - transporting proteins used by the thyroid gland to take up iodine from the blood.18, 38 The evolutionary reasons for this are clear: iodine is essential to the developing newborn brain, so the mother's body must have a direct means of supplying iodine to the nursing infant.18, 39

Instead, they help small shelters and rescue groups in rural areas (where there may be a high concentration of breeding, strays, and puppy mills) by transporting the animals to urban parts of the country where there are more potential adopters.

(In the global time average, diffusion of latent heat is in the same direction as sensible heat transport, but latent heat will tend to flow from higher to lower concentrations of water vapor (or equilibrium vapor pressure at the liquid / solid water surface), and regionally / locally, conditions can arise where the latent heat and sensible heat fluxes are oppositely directed.)

As I mentioned above, this is not hard to understand if you look at heat transport as a diffusion phenomenon, i.e., as flow in accordance with the laws of probability from a region characterized by a higher concentration (of fast molecules or fast electrons) to one with a lower concentration.

Consequently, the high methane concentrations with distinct positive δ13C - CH4 and δ2H - CH4 values in the shallow groundwater from active areas could in principle reflect the transport of a deep methane source associated with gas drilling and hydraulic - fracturing activities.

High levels of public transport density are usually accompanied by higher levels of traffic - related noise and air pollution, especially in urban environments typified by a concentration of tall buildings.54 Both excessive traffic - related noise and air pollution have been linked to stress, inability to psychologically restore and depression.55 56 One of the main features included in the measure of street connectivity used in this study was the presence of bridges, overpasses or tunnels.
