Analyses of ephemeral granitic drainages of <5 km at South Mountain metamorphic core complex, central Arizona, reveal a previously undocumented process of bedrock strath formation in this setting. Granitic channel banks experience a higher degree of mineral decay than that of granitic channel floors. Electron microscope observations show that grussification along the granitic channel banks occu...

The working area of a screen-printed electrode, SPE, was modified with the enzyme tyrosinase (Tyr) using different immobilization methods, namely entrapment with water-soluble polyvinyl alcohol (PVA), cross-linking using glutaraldehyde (GA), and cross-linking using GA and human serum albumin (HSA); the resulting electrodes were termed SPE/Tyr/PVA, SPE/Tyr/GA and SPE/Tyr/HSA/GA, respectively. Th...

The survey on Azolla diversity revealed that pinnata and microphylla are the two species found throughout agro-climatic zones of Tamil Nadu.The pot-culture experiments to screen strains for local adaptability Tiruvallur district during cold months (Nov-Dec), most grow with high growth rate (5 7 days doubling time) Jan-Feb, time increased from 7.5 9.5 days.Among different studied, A. recorded a ...

Azolla is an aquatic pteridophyte widely distributed in the water bodies. It has been traditionally used as a biofertilizer for rice paddy fields owing to its potential to fix atmospheric nitrogen [1]. In addition to this it has several other uses and Wagner [2] referred it as “green gold mine”. The plant system has the inherent capacity to synthesize several biologically active constituents wh...
