摘要:
The present invention provides a combination used for absorbing toxins in feed, comprising 1-10% by weight of clay and 90-99% by weight of yeast manna oligosaccharide, wherein the yeast manna oligosaccharide is extract of yeast cell wall which is separated from Saccharomyces cerevisiae. The biotoxin sorbent product can be used to feed any animals, including livestock, fowls, marine lives and ruminants. When mixing with feed, owing to its strong toxin adsorption capability, this absorbent may reduce the amount of toxins entering bodies of animals, thereby improving productivity and health of animals, reducing diseases caused by toxins.

Disclosed is a process of forming a pyrrole compound. The process comprises contacting an α-carbonyl oxime compound 1 and an α,β-unsaturated aldehyde 2 R1 and R2 in compound 1 are independently selected from the group consisting of H, a silyl-group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group, and an arylalicyclic group. The aliphatic, alicyclic, aromatic, arylaliphatic, and arylalicyclic groups comprise 0 to about 3 heteroatoms selected from the group N, O, S, Se and Si. R3 in aldehyde 2 is selected from the group consisting of H, a silyl-group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group, and an arylalicyclic group. The aliphatic, alicyclic, aromatic, arylaliphatic, and arylalicyclic groups comprise 0 to about 3 heteroatoms selected from the group N, O, S, Se and Si. The α-carbonyl oxime compound 1 an the α,β-unsaturated aldehyde 2 are contacted in a suitable solvent in the presence of a secondary amine. The compounds are contacted for a sufficient period of time to allow the formation of an N-hydroxypyrrole compound 3

摘要:
Techniques for encryption key destruction for secure data erasure via an external interface or physical key removal are described. Electrical destruction of key material retained in a memory of a storage device renders the device securely erased, even when the device is otherwise inoperable. The memory (e.g. non-volatile, such as flash) stores key material for encrypting/decrypting storage data for the device. An eraser provides power and commands to the memory, even when all or any portion of the device is inoperable. The commands (e.g. erase or write) enable zeroizing or destroying the key material, rendering data encrypted with the destroyed key material inaccessible, and therefore securely erased. Alternatively, the memory is a removable component (e.g. an external security device or smartcard) coupled to the device during storage operation. Removing and physically destroying the memory renders the device securely erased. The device and/or the memory are sealed to enable tamper detection.

Disclosed is a process of enantioselectively forming an aminoxy compound of Formula (3) In formula (3) R1 is one of an aliphatic group and an alicyclic group. R2 is one of hydrogen, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group and an arylalicyclic group. R3 is one of hydrogen, halogen, hydroxyl, and an aliphatic group with a main chain having 1 to about 10 carbon atoms. The respective aliphatic, alicyclic, aromatic, arylaliphatic or arylalicyclic groups of R1, R2, and R3 comprise 0 to about 3 heteroatoms independently selected from the group consisting of N, O, S, Se and Si. The process includes contacting a carbonyl compound of Formula (1) and a nitroso compound of Formula (2) in the presence of a chiral catalyst. The chiral catalyst is a compound of Formula (IX)

摘要:
Generally, a method and apparatus provides for search results in response to a web search request having at least two search terms in the search request. The method and apparatus includes generating a plurality of term groupings of the search terms and determining a relevance factor for each of the term groupings. The method and apparatus further determines a set of the term groupings based on the relevance factors and therein conducts a web resource search using the set of term groupings, to thereby generate search results. The method and apparatus provides the search results to the requesting entity.
