bushranger awning Deciphering the molecular communications along the gut-brain axis can help in understanding the pathophysiology of neurodegenerative diseases and exploiting the gut microbiome for therapeutics.However, gut microbes and their metabolites have a multifaceted role in mediating both brain physiology and neurodegenerative pathology.The

The self-cleaning hydrangea red sensation or oxidation capacity of the atmosphere is principally controlled by hydroxyl (OH) radicals in the troposphere.Hydroxyl has primary (P) and secondary (S) sources, the former mainly through the photodissociation of ozone, the latter through OH recycling in radical reaction chains.We used the recent Mainz Org

In this paper we introduce techniques for efficient multicast video streaming in UMTS networks where a video content has to be conveyed to multiple users in the same cell.Efficient multicast data delivery in UMTS is still an open issue.In particular, suitable solutions have hydrangea red sensation to be found to cope with wireless channel errors, w
