Methylation and demethylation of organic and inorganic compounds are pervasive biotransformation processes in various plants . Plant uptake, accumulation as well as volatilization of the contaminants can be significantly altered when methylation and demethylation processes occurred. Some researchers found that 6-MeO-BDE-47 was readily accumulated in maize shoots compared with 6-hydroxy-2,2′,4,4′-tetrabromodiphenyl ether Selenite and arsenic were…

The methodology is applied to a case study in Qatar encompassing open-field agriculture, conventional and hydroponic greenhouses. Nine risk factors are selected to perform the AHP, including temperature, humidity, solar radiation, Soil Quality , groundwater depth, groundwater recharge rate, groundwater salinity and groundwater pH.In this study, a geospatial risk composite indicator that represents the environmental condition…

An alternative to the AD hypothesis that could capture this curvature is the existence of two populations of viruses as used in Petterson et al. , one decaying slower than the other. However, a closer examination of the double exponential model revealed that it was not time invariant. This means that the time taken to…

Even though Namibia has one of the highest average solar radiation levels in the world, the nitrate levels in the RAS are still greater than the recommended maximum levels of 200 ppm for the reared tilapia . Fig. 4 shows that the RAS nitrate concentration is close to the trout’s allowable threshold of 40 ppm,…

Since the translation of public signs is assigned responsibility to convey accurate and clear information to the recipients, the translators need to consider and respect foreign tourists’ culture, psychology and express habit to facilitate the understanding of translation. 4) Strengthening the cooperation between universities and scenic spots In academia, the translation of public signs has…

The shoot regeneration frequencies changed with the variation of hormonal concentrations used in the same medium in this experiment . NAA at 1.0 mg/L in MS media showed the highest 80% ± 2.89% root initiation compared to IBA 70% ± 5.20% at the concentration of 1.0 mg/L . The increasing concentrations of IBA and NAA…

However, unlike the vast variety of commercial fertilizers available for traditional soil-based planting, relatively limited commercial nutrient supplements are currently available for application in hydroponic planting, especially those using PH derived from enzymatic-digested processing-wastes. In this paper, we aim to determine the effects of protein hydrolysate  on hydroponic planted lettuce. We would like to test…

Overall emissions for pepper production were lower than those found for the three lettuce cycles combined. This finding can be explained by the greater weight obtained with pepper production, making a direct comparison between crops difficult with a functional unit only accounting for the obtained yield. The results show that the long cycle of pepper…

By using the semivariogram, it is possible to describe, both qualitatively and quantitatively, the spatial variation and to obtain the parameters that determine kriging. In this way,the values of the nugget , plateau and range effects and determination coefficient and Spatial Dependency Index were obtained. The nugget effect ranged from 4.01 to 17.00; while the plateau from…

A companion experiment documented the response of native and invasive genotypes to experimental grazing and found that NC genotypes produced the greatest biomass and FR genotypes produced the least. Brodersen et al. 2008 showed that FR genotypes have higher photosynthetic rates but slower growth rates in a common greenhouse study suggesting that increased carbon gained…
