They are: first, adequate laws, rules and regulations, which govern people living close together and sharing common services; second, better spatial planning and design, which optimize density, connectivity and diversity; and third, a viable financial model, which sustains the functioning of the city and ensures economic prosperity.
The cost of staying in the game has soared just as the advertising model which sustained newspapers for the best part of two centuries appears to be faltering.
The C2 endplate in the Cage + Plate model, which sustained 2.2 to 8.3 times greater stress than in Cage + TARP model, had higher stress than that in Cage + TARP model in all motions (Fig. 5).
To study whether hydrodynamic delivery alone, or in conjunction with delivery of φC31 integrase for long-term transgene expression, could facilitate tumor formation, we used a transgenic mouse model in which sustained induction of the human C-MYC oncogene in the liver was followed by hydrodynamic injection.
The reactor is modeled as a CSTR, which sustains an exothermic first-order reaction.
Instead, as Wenger, Hill-Wood, Kroenke, Keswick and the rest wish, Arsenal will continue with the self-sustaining model which they feel places the club in the best possible position for a future likely to be shaped by Uefa's looming Financial Fair Play guidelines.
Once it's scaled" — that is, once it has expanded to its full potential — "it's a self-sustaining, profitable model, which opens the door to reaching large numbers of people who need to be reached by this tool of access to capital".
"You have to look at this from the point of view of some of the chairmen who have been pouring money from their own personal wealth into these clubs for years to sustain this model, which doesn't work - it's not worth the money they're paying the players.
This concept has recently been challenged by the cancer stem cell (CSC) model, which suggests that tumors are sustained by a distinct population of cancer cells with stem cell-like properties that self-renew and are also capable of generating the full repertoire of cell types found within tumors, including those contributing to tumor vasculature [ 2].
And for funders to recognise that sustaining a publishing model which is obsolete and costly stifles industrial innovation.
It also represents a continued investment in the flash sale model, which other sites like Fab have not been able to sustain.
