Plankton Production and its Control

Biosynthesized Zinc Oxide nanoparticles control the growth of Aspergillus flavus and its aflatoxin production

The infection of Aspergillus flavus and its aflatoxin production pose a severe threat to humans, animals as well as plants life. Their inhibition using green techniques are considered as one of the important challenges. The present study outlines the antifungal activity of the ZnO nanoparticles (NPs) synthesized from lemongrass leaf extract and their effect on the mycelial growth of <e...

Upstream control of the frontal jet regulating plankton production in the Alboran Sea (Western Mediterranean)

Using a coupled physical-biological model, we document that a 30 km wide meandering jet constitutes a major source of biological enrichment in the Alboran Sea (Western Mediterranean) even in the absence of wind forcing and tidal dynamics. The level of enrichment is shown to vary markedly during the year depending on the upstream characteristics of the jet as it exits from the Gibraltar Strait. ...

Mineland seepage and its control

Viral release of iron and its bioavailability to marine plankton

The biological availability of Fe has been demonstrated to strongly influence both primary and secondary production in pelagic as well as coastal upwelling high-nutrient low-chlorophyll (HNLC) regimes. Although nearly all of the dissolved Fe in marine surface waters is thought to be complexed by organic ligands, the character and origin of these Fe-organic complexes remains a mystery. Here we r...

Production and quality control of 82mRb and primary PET scans using its radiopharmaceutical for heart examinations [Persian]

According to the importance of positron emitters in nuclear medicine, 82mRb was produced as a member of this group of radiopharmaceuticals. After being converted into an injectable form, enough information was provided for imaging with this radiopharmaceutical. 82mRb with high radioisotopic purity and half-life of 6.5 hours, in chloride form, can be considered as a suitable positron emitt...
