A CONVENIENT SYNTHESIS OF MACROCYCLIC DIAMIDES
Some new macrocyclic dibenzotrioxadiamides, dibenzotetraoxadiamide, dibenzopentaoxadiamide, dibenzothiatrioxadiamide, tribenzotrioxadiamides and tetrabenzohexaoxadiamide (14-21), (26) and (27) have been prepared. These compounds were obtained in the macrocyclization step by reacting the diamine (4) with appropriak dicaxboxylic acid dichlorides (5-13) and (24). The cyclization does not requ...
متن کاملConvenient Conversation Exploring support for initiating mobile communication
Office workers are today often faced with the dilemma of being focused on the present activity and yet available for incoming calls on their mobile phone. Current technology does not support this situation. Many intrusive calls seem to occur as consequence of the lack of information about the recipient's context. The focus of this thesis is the initiation of mobile communication via mobile pho ...
متن کاملWomen at war: The crucible of Vietnam
Relatively little has been written about the military women who served in Vietnam, and there is virtually no literature on deployed civilian women (non-military). We examined the experiences of 1285 American women, military and civilian, who served in Vietnam during the war and responded to a mail survey conducted approximately 25 years later in which they were asked to report and reflect upon ...
متن کاملA Convenient Small Osmometer
A description is given of a simple, rugged instrument for determining the osmotic pressure developed by a solution of a high polymer. Other small osmometers described previously [1, 2, 3, 4, 5]/ have been, in some respects, too inconvenient to use. Although relatively easy to make, glass osmometers are fragile and may require frequent repairs. Small metal osmometers, in addition to being rugged...
متن کاملA convenient differential category
In this paper, we show that the category of Mackey-complete, separated, topological convex bornological vector spaces and bounded linear maps is a differential category. Such spaces were introduced by Frölicher and Kriegl, where they were called convenient vector spaces. While much of the structure necessary to demonstrate this observation is already contained in Frölicher and Kriegl’s book, we...
