Synthesis and thermo-mechanical characterization of bare and composite chitosan film
(2012)
In this present work, chitosan thin films were synthesized via two synthesis techniques: sol
casting and spin coating. Subsequently, silver nanoparticles or carbon black particles were
incorporated into the polymeric ...
An acoustic method for real time air bubble detection in simulated blood vessels
(2012)
Exposure to significant changes in ambient pressure commonly occurs in divers during surfacing. These changes induce the formation of nitrogen bubbles in tissues and the presence of these bubbles can cause symptoms of ...
Tres potyvirus que afectan las cucubitáceas en Puerto Rico: resistencia genética y comportamiento biolóco
(2012)
Tropical pumpkin (Cucurbita moschata) and watermelon (Citrullus lanatus) are the most important cucurbit crops in Puerto Rico (PR). Potyviridae is an important family of viruses that severely affects these crops in PR. ...
