摘要:
An altitude simulation system is disclosed for simulating an altitude within an enclosure or mask, wherein various improvements are provided, including: (a) a more effective use hypoxpic air generated by the system via recirculating techniques and improvements in air leakage, (b) improvements in determining when a simulated altitude is reached, (c) improvements in controlling hypoxic air generators so that peak electrical power loads are reduced and there are enhanced failsafe features for protecting the health of users, (d) using a pulse oximetry device for measuring oxygen saturation in a user's blood to thereby vary the oxygen content in the air provided to the user.
摘要:
The present invention relates to improved therapeutically active nanocomposite microstructure compositions, including nanoparticle compositions and nanoparticle preparations. Preferred embodiments include nanoparticle compositions comprising nanoparticles of a therapeutically active agent dispersed in a carrier matrix. The invention also relates to a method for preparing said compositions and preparations using solid-state mechanochemical synthesis. Further, it relates to therapeutic products produced using said compositions and to methods of treatment using the compositions.
摘要:
The present invention is directed to methods for providing a polyelectrolyte multilayer film at a liquid-liquid interface. Such methods include steps of sequentially-depositing layers of cationic and anionic polyelectrolytes at a liquid-liquid interface that is formed between immiscible first and second liquids whereby a polyelectrolyte multilayer film is provided at the liquid-liquid interface. In certain preferred embodiments, the first liquid is an aqueous solution and the second liquid is a liquid crystal. In alternative embodiments, the first liquid is an aqueous solution and the second liquid is an oil. The invention further encompasses polyelectrolyte multilayer films provided by the disclosed methods as well as applications utilizing such materials.
摘要:
Process for encapsulation of an uncharged crystalline solid particle include treating the crystalline solid particle material with amphiphilic substances and subsequently coating the material with a layer of charged polyelectrolyte or coating the material with a multilayer comprising alternating layers of oppositely charged polyelectrolytes.
