Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers
Chemical Engineering &Technology, EarlyView.The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Interrelació entre evolució i desenvolupament embrionari [PDF]
, 2010 El desenvolupament embrionari és un procés complex pel qual una cèl·lula ou es transforma, després de la fecundació, en un organisme adult. Aquestes transformacions estan controlades per xarxes d'interacció entre gens.

Hypoxic Cell Waves around Necrotic Cores in Glioblastoma: A Biomathematical Model and its Therapeutic Implications [PDF]
arXiv, 2012 Glioblastoma is a rapidly evolving high-grade astrocytoma that is distinguished pathologically from lower grade gliomas by the presence of necrosis and microvascular hiperplasia. Necrotic areas are typically surrounded by hypercellular regions known as "pseudopalisades" originated by local tumor vessel occlusions that induce collective cellular ...

Chemistry – A European Journal, EarlyView.This article describes the synthesis, along with the full photophysical and computational characterization, of a series of push‐pull boron complexes comprising a sterically hindered donor connected to a pyrimidine‐based O^N^O boron chelate. Incorporation of the dimethylacridan derivative into an organic light‐emitting diode led to the observation of ...
