The suspending property of a new polysaccharide gum derived from Afzelia Africana (family Fabaceae) seed have been investigated using Sodium carboxymethylcellulose as reference standard. Deflocculated and flocculated(using 1% solution of Aluminium Chloride) Zinc oxide suspensions were prepared using 0.5%w/v,1.0%w/v,2%w/v and 4%w/v of Afzelia africana gum, sodium carboxymethylcellulose and binar...

The purpose of this study is to evaluate the use of arabinoxylan as potential suspending agent, an effective alternative to commercially used excipients for the preparation of pharmaceutical suspensions. Alkali extraction was done to separate arabinoxylan from ispaghula (Plantago ovata) seed husk by alkali extraction its physicochemical characterization was done and the suspending properties of...

In their everyday lives people flexibly handle many tasks. They work on one at a time, make quick decisions about which one to work on, and put aside tasks whenever attending to them is not required to achieve the task’s goal. This last capability is critical because rather than fixate on a blocked task, a person can work on some other task. For example, a person making bean soup wouldn’t watch...

The period enforcer algorithm for self-suspending real-time tasks is a technique for suppressing the “backto-back” scheduling penalty associated with deferred execution. Originally proposed in 1991, the algorithm has attracted renewed interest in recent years. This note revisits the algorithm in the light of recent developments in the analysis of self-suspending tasks, carefully re-examines and...

Bacillus subtilis strain 5230 endospores suspended in a variety of suspending media at a concentration of ca. 10(8) per ml were heated at 95 and 75 C. The effect of the heating at 75 C was measured by plate count, and was reported as the heat-activated decimal fraction of the total viable-spore population. Thermal inactivation at 95 C was influenced by the suspending medium. No effects on heat ...

The mechanisms responsible for intrapancreatic digestive enzyme activation as well as the relationship between that activation and cell injury during pancreatitis are not understood. We have employed an in vitro system in which freshly prepared pancreatic acini are exposed to a supramaximally stimulating concentration of the CCK analog caerulein to explore these issues. We find that in vitro tr...
