Seeking Valuable pH Paper

Which Ph Paper?! No

In anaesthetic practice it is occasionally necessary to make a rapid and accurate measurement of the pH of the gastric contents. A simple and convenient method is to use paper impregnated with a suitable indicator, the change in colour being read against a comparison chart provided with the paper. The purpose of this study was to compare the accuracy of interpretation of five different indicato...

Studying Team Cognition during Collaborative Information Seeking: A Position Paper

Team cognition concepts are important in the collaborative information seeking (CIS) community. Yet, while this importance has been recognized there is a lack of research on team cognition within CIS. We take the position that team cognition concepts and measurements can be very useful to CIS researchers . This paper provides an understanding of what team mental models and common ground are. We...

Regular Paper pH Profile of cytochrome c-catalyzed tyrosine nitration*

In the present study, we investigated how cytochrome c catalyzed the nitration of tyrosine at various pHs. The cytochrome c-catalyzed nitration of tyrosine occurred in proportion to the concentration of hydrogen peroxide, nitrite or cytochrome c. The cytochrome c-catalyzed nitration of tyrosine was inhibited by catalase, sodium azide, cystein, and uric acid. These results show that the cytochro...

PAPER MILLIONAIRES: How Valuable is Stock to a Stockholder Who is Restricted from Selling it?

Many firms have stockholders who face severe restrictions on their ability to sell their shares and diversify the risk of their personal wealth. We study the costs of these liquidity restrictions on stockholders using a continuous-time portfolio choice framework. The economic cost of these restrictions can be large and many stockholders would actually be better off if they could sell their rest...
