Due to the rotational motion of the water, the levels of turbulence kinetic energy are increased leading to vigorous mixing and hence to uniform exposure to UV radiation. Since the UV lamps are arranged circumferentially around the outside of the quartz cylinder, pathogens that may become imbedded into suspended solids experience increasing probability of receiving …

Often considered “the elephant in the room,” some of the old prophecies on the existence of biophysical limits to population growth are going to be central in the analysis of the future of food security . It has been argued that there is an urgent need to contain the escalating demand for food commodities by stabilizing …
Depending on the depth of the deposit, oil sands are extracted using two different methods―surface mining and in situ drilling . In situ technology requires less water than surface mining . Bitumen from mined oil sands is a low-quality product that needs to be upgraded through a water-demanding process into synthetic crude oil before being delivered …

The surface of the bubbles, as shown earlier, is proposed to contain adsorbed hydroxide ions arranged in rhomboid unit cells, and by vector addition it is clear that the least repulsion to oxygen molecule to diffuse through the hydroxide ions would be at the centre of each rhombus, which would be limited to a greatly …
Metal localization and elemental associations in plants were investigated with X-ray and electron microscopies and X-ray microtomography.Particular emphasis was placed on the phenomenon of ‘simultaneous hyper accumulation’and its relationship to metal co-tolerance.Metal localization and elemental associations in A.murale were investigated with SXRF, CMT, SEM-EDS and XAS.Two-dimensional SXRF images of A.murale leaves revealed a distinctive localization pattern for …

OsPRR95 corresponds to Arabidopsis PRR, AtPRR5 or AtPRR9.A report has revealed that triple mutant prr 9–11 prr 7–10 prr 5–10 Arabidopsis exhibit better salt, drought and cold tolerance than wild type, and thus suggested that PRR5, PRR7 and PRR9 are involved in the diurnal cold stress-initiating stress response by mediating the cyclic expression of stress …
These toxic elements can be bio-available to terrestrial and aquatic organisms, including crop plants, and could be further bio-accumulated via the food chain causing damage to humans.Since these metals cannot be degraded, current remediation approaches include excavation or capping, with a very high cost and damage to ecosystems.In many cases, these options are not economically …

Taken together, these data indicate that MsLEC1 and MsLEC2 genes, as well as the orthologous gene MaLEC, are expressed in the youngest cells of indeterminate nodules of both alfalfa and white sweetclover. Moreover, the genes that encode these soluble lectins are also expressed in root tips. MsENOD40 gene expression. We hypothesized that expressing the lectin transgenes would not …

Microfluidic platforms have also been successfully employed to study the interactions between the root, microbiome and nematodes in real time . In the systems, additional vertical side channels are connected perpendicularly to the main micro-channel to enable introduction of microorganisms and solutes to the roots in a spatially and temporally defined manner . A recent …
Since 1984, farming and grazing lands have been converted to urban development at an average rate of 40,000 acres per year . At this rate, and considering the higher rate of emissions from urban versus agricultural land, slowing agricultural land conversion represents one of the largest opportunities for agriculture to contribute to California’s climate plan. …
