In this study, gelatin microspheres containing lactic acid were prepared by the polymerization technique using glutaraldehyde as the cross-linking agent. Dried microspheres were loaded by immersing them in an aqueous solution of lactic acid. In order to prepare microspheres with an appropriate drug release profile, the effect of time of cross-linking and the amount of cross-linking agent on the...

the simultaneous cross-linking and antimicrobial finishing of bleached cotton and cationized cotton by 3-chloro2-hydroxypropyl trimethyl ammonium chloride (quat-188) with butane tetracarboxylic acid and nano titanium dioxide is studied and explored in the current study. butane tetracarboxylic acid (btca) as a cross-linking agent can be linked to the cotton cellulosic chains by covalent bonds an...

A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. Mechanical...

We suggest a novel way for formalizing knowledge and belief of intelligent agent and argue that this is the notion we need to formalize agents in Distributed Artificial Intelligence. We introduce the notion of algorithmic knowledge — a concept that is suited for establishing a direct link between and agent’s available resources and his knowledge. We show that our concept of knowledge is useful ...

The present invention relates to a soybean-based adhesive resin including a soybean flour and a cross-linking agent. The cross-linking agent is reacted with the functional groups in the soybean flour to form an adhesive resin. The present invention also relates to a method of making a soybeanbased adhesive resin. This method involves providing an aqueous solution of soybean flour and adding a c...

Chitosan microspheres of a small particle size and with good sphericity were prepared by a spraydrying method followed by treatment with a cross-linking agent. Owing to restrictions on the use of crosslinked chitosan microspheres in the pharmaceutical field, d,l-glyceraldehyde, a biocompatible reatant was used. The parameters studied affecting extent of cross-linking were cross-linking time and...
