Le malade deceda <lans le tableau d'oedeme pulmonaire aigli, apres quel­ques episodes d'hemiparesies resolutives.  A l'autopsie, il existait un myxcme...

determining the optimal location of wells with the aid of an automated search algorithm is a significant and difficult step in the reservoir development process. it is a computationally intensive task due to the large number of simulation runs required. therefore,the key issue to such automatic optimization is development of algorithms that can find acceptable solutions with a minimum number of...

objective: in vitro production of a definitive endoderm (de) is an important issue in stem cell-related differentiation studies and it can assist with the production of more efficient endoderm derivatives for therapeutic applications. despite tremendous progress in de differentiation of human embryonic stem cells (hescs), researchers have yet to discover universal, efficient and cost-effective ...

Microwave assisted extraction (MAE) tech-nique was employed for the extraction of pectin from black mulberry (Morus nigra) pomace in this research. The effects of process variables namely microwave power (300-900 watt), irradiation time (10-30 min) and liquid to solid ratio (15-30 mL/g) on the yield, degree of esterification (DE) and galacturonic acid content (GalA) of pectin were investigated ...
