A new experimental technique has been developed to measure the rate of removal of aggregate from built-up roofs in severe storms.
This suggests that the primary role of the parapet is to prevent removal of aggregate from the roof cavity, but that parapets are less effective at preventing aggregate motion within the roof cavity.
The technique was used to quantify the rate of removal of aggregate from a two-dimensional building as a function of the building parapet height and the wind speed.
The total amount of money spent at the federal level in the 2012 election by the top fossil fuel industry donors who would benefit the most from the removal of aggregate campaign finance limits was $11,504,213.
Samples from the aggregation assay, either before or after removal of aggregates by centrifugation, were assayed for RTA catalytic activity by incubation at 30°C for 1 h with 20 μg of yeast ribosomes in Endo buffer [25 mM Tris/HCl (pH 7.6), 25 mM KCl and 5 mM MgCl2].
The removal of aggregates appeared in non-reduced condition of SDS-PAGE by gel-filtration did not significantly affect the MSTN- or activin A-inhibitory capacity of FST315 (Lee et al. 2014).
After the initial removal of aggregates, the nanoparticles were sequentially centrifuged at speeds 2,767 × g, 11,068 × g, 24,903 × g, and 35,860 × g, producing groups A, B, C, and D, respectively.
After washing tree times with 50 ml PBS, low speed centrifugation, and re-filtering for removal of aggregates, the cells were resuspended in 10 ml PBS and filtered trough a cell strainer with a mesh size of 100 µm (BD Falcon, Bedford, MA, USA).
In some cases, for example neurodegenerative disease, it is clear that autophagy facilitates the removal of aggregate-prone proteins that lead to Huntington's and Parkinson's disease (45).
An increasing number of studies have shown that autophagy is stimulated in response to external stressors (such as starvation and oxidative stress) and internal needs (for example, removal of aggregate-prone proteins).
This results in aggregates of the protein being retained on the column for longer than their monomeric counterparts, thus facilitating the removal of aggregates [ 75].
