The aggregation of chlorophyll a
Archives of Biochemistry and Biophysics, 1964Abstract 1. 1. Aggregation of chlorophyll a in various nonpolar solvents has been demonstrated, and from the IR spectra the probable site of the hooking together of the molecules has been deduced. 2. 2. If chlorophyll a exists in the cell in a completely nonpolar milieu (as the visible spectroscopic studies suggest), then CCl4 solutions of ...

Seegers citrate thrombin was prepared from bovine plasma and purified on IRC-50 (XE-64) resin columns at room temperature. The preparation was examined in the ultracentrifuge to determine the sedimentation coefficient and Archibald molecular weight. All measurements were made at 20 °C.

Clustering in microemulsions: aggregation of aggregates
2007A model is presented that describes the clustering of microemulsion droplets from a thermodynamic point of view. It is based on two assumptions: one assumption is that the microemulsion droplets aggregate linearly. The other assumption is that the chemical potential per droplet is equal for all sizes of aggregates.

International Journal of Project Management, 1990
Summary: We investigate a problem how to reduce the size of large scale networks which arise as models in project management studies. We propose a method for the aggregation of nodes and arcs preserving all characteristics important for finding an optimal project management scheme.

Aggregate, Aggregation + Geotechnical Urbanism
2021Within the architectural engineering and construction industry we have developed diagrammatic representations and software translations of cultural patterns, extruded 2D cities, and built architecture of processed materials palettes. We are not yet able to diagrammatically compute the translation (intent to manifestation) of wild contexts and materials
