Osmosis from Elsevier is a powerful learning platform that helps students learn smarter and retain more information in a visual way. The app offers videos, ques…
laboratory measurements of plasma osmolality over-estimate the true osmotic stimulus of vasopressin when ineffective solutes such as urea or glucose are elevated. In that situation, plasmavasopressin must be assessed in relation to the “effective” plasma osmolality (ePos). This value can be estimated...
Photocatalysis can be described as “change in the rate of a chemical reaction or its initiation under the action of ultraviolet, visible, or infrared radiation in the presence of a substance—the photo catalyst—that absorbs the light and is involved in the chemical transformation of the ...
Physical therapy and cognitive rehabilitation therapy can be particularly helpful with sensory, motor, and cognitive symptoms. Finally, there’s also an increasing interest in the role of vitamin D as an effective treatment. 小结 多发性硬化:一种慢性进展性自身免疫紊乱疾病,最常见的类型是复发缓解型,...
If one of these doesn't develop as scheduled,depending on the severity,it may be described as a type of neurodevelopmental disorder,neuro referring to the brain. 假如某些能力没能按期形成,根据严重程度,可能会被诊断为神经发育障碍的一种。neuro指大脑。(前缀neuro-) ...
Osmosis, in simplest terms, can be defined as a natural process in which water molecules spontaneously move from a solution of low solute concentration (low osmotic pressure) to a solution of high solute concentration (high osmotic pressure) across a semipermeable membrane (Fig. 1a). The ...
as can be seen inFig. 8b. To invert this process and produce more amount of low-salinity water, an external pressure should be exerted on the high-salinity side to force the water molecules through the membrane, as shown inFig. 8c. The magnitude of this pressure should be greater than ...
system treats not only tap water but also treats well water. The water has been described as being better than any bottled water on the market. This system also comes with a one year guarantee of satisfaction and support for the life of the system. You can’t get much better than that....
The term “solute” applies to both ions and counter-ions, and to uncharged molecular species present in the solution. Once dissolved in aqueous media a salt forms a solute comprising hydrated ions and counter-ions. The uncharged molecular species can be referred to as “non-ionic species”....
as the unit is opened or is draining, a slight internal vacuum may occur within the membrane. During the occurrence of such a slight vacuum, the membrane can be flexed over a sharp edge of the internal metal fitting member making up a portion of the end fitting. A rather sharp bend of...
