On this basis, it is proposed that no new fragmentation theory is needed to describe aerosol particles if concrete fragmentation is regarded as a composite material explicitly considering microstructural features which create stress concentrations on the microscale.
To overcome the need to infect all tumour cells to achieve complete remission, new versions of ONYX-015 have been created that deliver pro-drug converting enzymes to tumour cells, which create high local concentrations of cytotoxic compounds following systemic administration of non-toxic substrates.
High concentrations of nitrogen dioxide cause inflammation of the airways and can also react to form other secondary pollutants, such as ozone, which create their own health problems.
"One of the biggest problems anywhere in the world... is the concentration of wealth, which creates a gap of those who have it and those who don't have it," said Buffett, whose foundation has given tens of millions of dollars to social programs in Mexico and Central America.
This design, to the best of our knowledge, represents the first time that a vacuum package (which creates thermal concentration) has been combined with a CPC-based optical concentrator for thermo-chemical applications.
"Resort communities tend to have a high concentration of restaurants and hotels, which creates an opportunity to reach quality suppliers, giving us access to the best product".
The particles will sediment by forming a moving boundary, which creates a concentration gradient that also induces diffusion flux.
Storage and burial of river sediments would also disturb the initial concentration of cosmogenic nuclides by radioactive decay, which creates a case where the measured nuclide concentration underestimates the steady-state nuclide concentration (Wittmann et al. 2011).
The embedded anodes appear to attract more chlorides to their vicinity which created variable chloride concentrations and non-uniform chloride penetrations in the laboratory specimens containing the embedded anodes.
Anterior cantilever resin-bonded prostheses fail as a result of a labio-lingual peeling action, which creates a stress concentration within the adhesive layer.
