InfoScout is a proactive recommender agent designed to aid the effective creation and exploitation of formal and informal networks of social relations that form an important part of knowledge management strategies of an organization. It helps a user ask the right set of people for help on a topic or a problem on hand. InfoScout watches a user performing a particular task and suggests other peop...

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Active Networking is an expanding field of research in towards a new way to provide services for customers. The facility to develop and put customized services in the network enables a new management architecture to support this evolution. In a telecom environment, for example, the services can be purchased according to the customer’s requirements. Furthermore, a lot of different services is of...

While the structure and dynamics of boundary layers on rigid no-slip walls in rotation dominated enclosed flows are still an area of active research, the interactions between rotating or swirling flows with a free surface have received comparatively less attention. For the most part, investigations in this area have been focused on clean free surfaces, which may be treated as stress-free. Howev...

For studying the morphology of bacteria in fixed smears, Knaysi (J. Bact., 49, 375) demonstrated the value of staining by a method showing the cell wall. Knaysi (J. Bact., 41, 141) developed a tannin alum fuchsin method which stains differentially the cytoplasm, cell wall, and capsule. It is the purpose of this note to report another cell wall stain in which the cell wall is positively charged ...

preparation of chitosan (cs) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low cs molecular weight (mw) was investigated in this study. diphtheria toxoid (dt) was used as a model antigen. the emulsion-solidification method was adopted for microencapsulation of dt.  in the first step, following the purification of semi-crude dt by the ion-exchan...

Cellular protein, pH, dissolved oxygen concentration, and static surface tension were measured during growth of Thiobacillus acidophilus on elemental sulfur in the absence and presence of up to 5,000 mg of Tween 80 per liter. The decrease in pH and the increase in sulfate production were observed to be less accurate measurements of growth when compared with the increase in cellular protein. The...

Multi-Agent Active Search (MAAS) is an active learning problem with the objective of locating sparse targets in unknown environment by actively making data-collection decisions. Recently proposed algorithms, although well-motivated from a theoretical perspective, are limited three key ways: they either explicitly myopic (e.g. respect to information gain) or introduce strong biases that fall sho...
