However, even under these conditions, the model was not successful in identifying triggering events. For example, there was a poor relationship between the powdery mildew index in a greenhouse near Monterey when the model was run with a temperature range of 65°F to 85°F . This relationship was improved somewhat by running the model for the…

More recently, both kauralexins and dolabralexins have been shown to accumulate under drought and below-ground oxidative stress, consistent with a possible protective role of diterpenoids in abiotic stress responses . Furthermore, a kauralexin- and dolabralexindeficient maize mutant an2showed increased susceptibility to both drought stress and pathogen attack . These findings highlight the biological importance of…

Studies thus far suggest that metal sequestration in most hyper accumulators mainly occurs in non-photosynthetic cells of the epidermis and surface structures, namely trichomes, as a mechanism to reduce accumulation in the metal sensitive photosynthetic apparatus . In S. alfredii however, Tian et al. reported that Cd concentrations were highest in stem parenchyma and leaf mesophyll tissues,…

At Santa Maria, nitrate nitrogen levels in leachate collected at 8-inch depth on all sampling dates ranged from 12 to 27 parts per million in PAM and untreated plots, which was 52% to 80% greater than those in other treatments . At Somis a similar trend was observed: nitrate nitrogen levels in leachate under PAM and untreated…

A recent study showed that the release from paints is ~3 to 27 μg/cm2 ·day, or in other terms, around 0.2 to 1.8% of the Cu NPs present in the paint were released in 180 days . Cu concentrations in water near the painted material can range from 40 to 630 mg/L; Cu can be…

Recently, nano-Mn3O4 was applied to leaves by spraying a suspension of 20 mg/L, after 20 days from the sowing of the seeds of squash plants until 40 days from sowing,improving the growth plant yield but decreasing the yield of fruit. Another study reported that nano-Mn2O3 applied at 6 mg/kg/plant promoted nutrient fixation in wheat, but…

A problem in conducting realistic toxicity studies is the likely transformation of the free particles into homo or heteroaggregates or even organic complexes in the real environment. There have been few studies that investigated the impact of size across a wide range of systematically varied particle sizes within a single study.On the other hand coating…

Underdeveloped feed value chains dominated by artisanal and small-scale producers are also important constraints to feed development in LMIC. Fig. 1 shows a typical LMIC feed value chain with emphasis on the weakest linkages that need development and the strongest ones that need to be enhanced. The feed value chains in LMIC are characterized by: limited…

The fraction of the adsorbed NO that is reduced depends on the temperature and the flow rate of N2 gas. Fig.10 shows the fraction of the desorbed NO integrated over the temperatures as the temperatures of the carbon bed was raised. As can be seen, the fraction of the total NO desorbed as NO reaches…

Among the studies on LSLAs and land grabbing, an alternative hypothesis has developed: what if the main driver of the contemporary global land rush were the need for water rather than for land? . Dell’Angelo et al. have described a “global water grabbing syndrome” to take into account the increasing dynamics of freshwater appropriation occurring as…
