The BGP Encapsulation Subsequent Address Family Identifier (SAFI) provides a method for the dynamic exchange of encapsulation information and for the indication of encapsulation protocol types to be used for different next hops. Currently, support for Generic Routing Encapsulation (GRE), Layer 2 Tunneling Protocol (L2TPv3), and IP in IP tunnel types are defined. This document defines support fo...

UDP encapsulation encompasses the techniques and protocols to encapsulate and decapsulate networking packets of various protocols inside UDP. UDP encapsulation has become prevalent in data centers, and in fact nearly all the solutions for network virtualization currently being proposed in IETF are based on UDP encapsulation. In this paper we present much of the recent work done by the Linux net...

A discussion of various strategies for the intrazeolite encapsulation of polymer filaments is given. Two examples are discussed in more detail: Poly(2-ethylaniline) and pyrolyzed polyacrylonitrile in zeolite hosts. Poly(2-ethylaniline) chains were synthesized within the three-dimensional channels of dehydrated zeolites X and Y via oxidation of the intrazeolite monomers with aqueous (NH4)2S20s. ...

It has been hypothesized that freeze-tolerance in anurans evolved from a predisposition for dehydration tolerance. To test this hypothesis, we dehydrated summer/fall-collected and winter acclimated freeze-tolerant chorus frogs and dehydration-tolerant, but freeze-intolerant, Woodhouse's and Great Plains toads to 25% and 50% body water loss (BWL). Following treatments, we measured glucose, glyco...

In rats, the hypothalamic neurotransmitter histamine participates in regulation of vasopressin secretion and seems to be of physiological importance, because blockade of the histaminergic system reduces dehydration-induced vasopressin secretion. We investigated whether histamine is also involved in regulation of vasopressin secretion during dehydration in humans. We found that 40 h of dehydrati...

background :  kefir contains lactic acid bacteria ( lactobacillus , lactococcus , leuconostoc , acetobacter and streptococcus ) and yeasts ( kluyveromyces , torula , candida , and saccharomyces ). kefiran is the polysaccharide produced by lactic acid bacteria in kefir.   methods :  kefiran was prepared from milk containing 0.5% fat and 10 grams kefir grains and was separated from kefir by ethan...
