22.06.2017  Natural aggregates (NA) are crushed and processed in crushing plants after the extraction stage in quarries. In the present study, the aggregates are divided into three scenarios, depending on the production methods. The first scenario considers the production of NA, the second scenario deals with the production of recycled aggregates (RA) with respect to construction and demolition waste, and ...

Productivity for the aggregates industry

In the aggregates industry, productivity is essentially a combination of tonnes per day and end output quality. As aggregates belong in the heavy-duty end of mining materials, machines and equipment must be able to handle high and constant loads. We offer proven, reliable and scalable productivity solutions. These are typically a combination of extremely durable products and equipment, industry leading service and support, and high performance parts, ensuring that the productivity

Aggregate production functions are reduced-form relationships that emerge en-dogenously from input-output interactions between heterogeneous producers and factors in general equilibrium. We provide a general methodology for analyzing such aggregate production functions by deriving their first- and second-order properties.

Protein aggregation - Wikipedia

Protein aggregation is a biological phenomenon in which intrinsically disordered proteins or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly. Mis-folded protein aggregates are often correlated with diseases. In fact, protein aggregates have been implicated in a wide variety of disease known as amyloidoses, including ALS, Alzheimer's ...

Aggregate Productivity - an overview ScienceDirect Topics

Since aggregate labor is in fixed supply, aggregate output is a weighted average of the sectoral productivity shocks: (86) ln ( y) = ∑ i = 1 n ν i ln ( z i). In this expression, y is aggregate output and the νi are weights that are constructed from the input–output table.
