This article deals with the problem of contemporary innovative process and organizational emergence in the french non profit sector, through a study of innovative micro-projects financed by the program of measure 10B in FSE (Social Fund European). To study processes of emergence and development...

We study a reduced Poisson–Nernst–Planck (PNP) system for a charged spherical solute immersed in a solvent with multiple ionic or molecular species that are electrostatically neutralized in the far field. Some of these species are assumed to be in equilibrium. The concentrations of such...

A response surface methodology (RSM) was used to evaluate the effects of pH and microalgal biomass concentration (BC) on alkaline flocculating activity for harvesting one freshwater green algae <i>Scenedesmus quadricauda</i> #507 and one marine diatom <i>Chaetoceros</i> <i>muelleri</i> #862. The pH value and BC were...

Microalgal biofuel research in China has made noticeable progress, and algae cultivation for biofuel production is considered to be an important contribution to <em>Greenhouse Gas</em> (GHG) mitigation and energy security. In this paper, the algal biofuel potentiality in China was reviewed from the...

Algae have been considered as a promising biodiesel feedstock. One of the major factors affecting large-scale algae technology application is poor wintering cultivation performance. In this study, an integrated approach is investigated combining freshwater microalgae Chlorella zofingiensis...
