From the aquaponic facility at Caldwell, two water samples were collected per week: one from the fish tank and the other from the plant bed which was used to grow Romaine Lettuce, watercress, lettuce and green peppers. Similarly, from the facility at Bryan, three water samples were collected: one from the Tilapia tank, one from the …

The results suggest the significance of light intensity and media composition on morphogenesis
Bacopa monnieri Wettst., an extensively documented medicinal plant, for its nootropic properties had witnessed a burgeoned interest towards analyses of plant growth, role of culture conditions and elicitations on metabolites yield and their bio-activities.The growing disease burden of neurological disorders, especially in developing countries like India , further augment the need to explore the phyto-pharmacological importance …
The trend of root cutting force was predicted by the response surface method
The tension meter was suggested to be placed vertically because the results from the tensile experiment were affected by the inclined angle of the tension meter. The tension meter was pull up slowly at a constant speed until the root of hydroponic lettuce was separated from the planting board. Then the maximum pulling force in …

Photosynthetic production is the source of rice grain yield formation
Leaf area, photosynthetic potential and crop growth rate are important indexes for representing the photosynthetic capacity of a population. Wu et al. suggested that the leaf area, photosynthetic potential and population growth rate of superhybridized japonica rice were significantly greater than those of Shanyou 63 control rice at the middle and late stages. Huo et al. …

Open-field culture does not allow a strict control neither of the growing conditions nor the secondary metabolism
Higher antioxidant activity has been measured in ginseng leaves and fruits than in roots, possibly in association with the 4e9-fold higher phenolic contents of fruits and leaves than roots. However, the beneficial effects of these phenolic compound-rich fruits and leaves remain unclear. Short-term hydroponic-cultured ginseng is a widely available, eco-friendly plant that cultivated in pesticide-free …
Caffeine is hydrophilic whereas carbamazepine is hydrophobic due to its dibenzoazepine structure
Similar to mineral wool, pumice is also a neutral material containing less than 1% organic matter. Thus, it showed minimal sorption affinity to most of the studied compounds during the initial contact time. Caffeine is a notable exception. We speculate that caffeine’s low molecular mass allowed high mass transfer into pumice’s large number of pores. …
Rice is a staple food and the main source of dietary energy for more than 50% of the population in the world
Therefore, the systems showed greater bacterial diversity. Microorganisms gradually adapt to the environment and accumulate, resulting in an increase in bacterial community richness with the extension of culture time. At the same time, the dominant flora gradually occupy the dominant position, resulting in a decrease in the diversity of bacterial communities. The higher the concentration …
CIPS detected more ToxCast chemicals than solvent extraction of irrigation sources and plant tissues
These prior studies demonstrate the importance of rainfall to chemical dilution of wastewater in the land treatment reservoirs and receiving waters relative to upstream watershed sources of unplanned water reuse such as septic systems, livestock waste management, and agriculture. The extended exposure of chemicals to sunlight, biological degradation, and mixing for 10–14 days in reservoirs …
The results of this study show that cover crops can be used to mitigate soil and groundwater pollution
Therefore, based on those experiments, and taking into account the highest recommended doses of the selected products according to their labels, ground losses for each selected formulation were estimated as indicated in Table 2 and applied using a manual sprayer to each soil column. After application, a rainfall event of 120 mm was immediately simulated …
Higher magnifications revealed the presence of micro-focal necrosis in the centre of some lymphoid foci
Some weeks later, as no clinical improvement was noted, the lemur was anesthetized to perform a more detailed examination. A big firm mass was revealed in the epigastrium by the abdominal palpation and it was confirmed by radiographs: a large radiopaque mass about 3 – 4 cm in diameter. Two days later a laparotomy was …
