A proposed role for the Ca ion in the chemotactic response of Physarum polycephalum
… form an intimate association with the surface membrane and depending on the local [Ca⁺⁺] , the filaments can cause the membrane to relax or become rigid, (3) Ca⁺⁺ fluxes across the external membrane (viz. efflux and influx) regulate the state of contraction in the proposed actinomyosin-surface …

Determining the Refractive Index of Phytoplankton via Direct Measurement of Cellular Structures
… for distinct groups, largely differentiated by external membrane (Diatoms, Coccolithophores, Dinoflagellates, and Ciliates). Additionally, differences between species were seen in the volume portions of different structures, further necessitating the use of different bulk RIs for different …

Diffusion and reactions of nitric oxide, oxygen, and superoxide in cells and culture media
… to NO, which diffuses readily across cell membranes. Superoxide is generated also by an NADPH oxidase on the external membrane surface of macrophages, thereby delivering it to the extracellular fluid at significant rates. The research in this thesis aimed to determine the concentration …

Estudio de la filtración de fangos anaerobios con membranas sumergidas de fibras huecas y tubulares externas empleadas en biorreactores de membranas
En esta tesis se estudia el fenómeno del ensuciamiento de las membranas de ultrafiltración empleadas habitualmente en bioreactores anaerobios de membrana, AnMBR. Este ensuciamiento es el principal cuello de botella al que se enfrenta el desarrollo de esta tecnología. Dadas las ventajas que los …
