Encyclopedia :: encyclopedia : Agent   (Site not responding. Last check: 2007-10-12) Each agent possesses the ability to act autonomously; this is an important distinction because a simple act of obedience to a command does not qualify an entity as an agent. Nevertheless in business and in law an agent is often acting on a principal's behalf and has a legal duty to act in that person's best interest. Agent (law) - In law an agent is a person authorized to act for another person or organization, with delegated authority, such as a person holding a power of attorney under the law of agency also known as an "attorney-in-fact" in contrast to an "attorney at law". www.hallencyclopedia.com /Agent   (523 words)

Buffer solution - Wikipedia, the free encyclopedia Buffer solutions are solutions which resist change in hydronium ion and the hydroxide ion concentration (and consequent pH) upon addition of small amounts of acid or base, or upon dilution. Buffer solutions consist of a weak acid and its conjugate base (more common) or a weak base and its conjugate acid (less common). Industrially buffer solutions are useful in fermentation processes, and for setting the correct conditions for the dyes used in colouring fabrics. en.wikipedia.org /wiki/Buffer_solution   (728 words)

MVS Solutions - Buffered resorbable internal fixation devices and methods for making material therefore Exemplary buffering materials that may be implemented according to the invention include the salts of inorganic acids, the salts of organic acids, or the salts of polymeric organic acids. The polymers serving as buffers may be stable to hydrolysis, such as "addition" or "vinyl-type" polymers, i.e., those polymers formed by polymerization of monomers containing carbon-carbon double bonds (substituted ethylenes) to form a chain of repeating units in which the repeating unit has the same composition as the monomer. A buffer solution comprising a chosen buffer in a suitable solvent is forced into the pores of the open celled foam by repeated cycles of evacuation (degassing) and repressurization (by emitting air at atmospheric pressure or higher). www.mvssolutions.com /CSI-6419945.html   (8203 words)

Experiment 2 Buffering agents are molecules that prevent a system from changing too much. The buffering agent should be highly water soluble and insoluble in organic solvents. The buffering agent should be available as the zwitterion because associated ions such as chloride or sodium may adversely affect your system. www-class.unl.edu /bioc433/experiment2.htm   (2129 words)

MVS Solutions - Resorbable interbody spinal fusion devices Most preferably, the buffering or neutralizing agent is selected from a group of compounds wherein the pKa of the conjugate acids of the buffering or neutralization compound is greater than the pKa of the acids produced by hydrolysis of the polymers from which the device is prepared. The buffering compound included in the bioerodible material of the invention may be any base, base-containing or base-generating material that is capable of reacting with the acidic products generated upon hydrolysis of the bioerodible polymer. Buffers, reinforcement materials, growth factors, etc., may also be included in processing of the spinal fusion device to exhibit this phenomenon. www.mvssolutions.com /CSI-6241771.html   (6917 words)

FIPA Message Buffering Service Specification Buffering will happen whenever there is no connection to the next destination, and the address of the next destination is the one for which buffering has been previously requested. If the destination that has requested the message buffering does not request the MB to forward the buffered messages before the timeout expires (keep-time), messages are either forwarded to the next address in the message envelope (if there is such an address) or an error message is sent as specified in [FIPA00067]. However, because of physical limits, it may happen that the buffer overflows, and the MB must raise an error (i.e., the entity that requested buffering, may still have to be prepared for lost messages because of possible buffer overflow). www.fipa.org /specs/fipa00092/PC00092.html   (2257 words)

FIPA Message Buffering Service Specification The Message Buffer can be a standalone FIPA-addressable entity, that is, something that does not necessarily belong to any physical AP, but it also can be part of an AP.

Messages [11] and [12]: The Message Buffer forwards the messages ([6] and [7]) that were buffered while the agent dummy was unreachable. www.fipa.org /specs/fipa00092/XC00092B.html   (2341 words)
