Abstract:
... Subsurface geochemical behavior of As(V) with Fe(II) was studied under strict anoxic conditions. Abiotic reduction of As(V) (0.1 mM) to As(III) by aqueous Fe(II) and sorbed Fe(II) in pH range 5.0-7.0 and Fe(II)aq concentration (0.6-1.2 mM) was investigated along with the effect of As(V) on the oxidation of Fe(II) by dissolved oxygen (DO). Although the reduction was thermodynamically feasible for h ...

Abstract:
... Sub-daily rainfall intensity has a significant impact on runoff and erosion rates in northern Australian rangelands. However, it has been difficult to include sub-daily rainfall intensity in rangeland biophysical models using historical climate data due to the limited number of pluviograph stations with long-term records. In this paper a new empirical model ('Temperature I15' model) was developed ...

Abstract:
... The population of microsclerotia of Verticillium dahliae in soil affects the severity of wilt diseases caused by the fungus. The number of microsclerotia (MS) in soil is usually estimated by colonies recovered from plating of soil samples in various forms on solid media, and this value can be useful in making decisions on disease management. Most protocols, however, lack efficiency in making accur ...

This has prompted concern over the resource and has initiated an assessment of the current status of the stock. The limited available biological information suggests that the main pulse of recruitment into the lagoon occurs in the first few months of the year, but that ...
