Germination, physio-anatomical behavior, and productivity of wheat plants irrigated with magnetically treated seawater

Salinity is an abiotic stress that reduces the seed germination and productivity of wheat. The objective of this study was to assess the impact of irrigation with magnetically treated seawater on the germination, growth, certain physiological and anatomical parameters, and production attributes of wheat (Triticum aestivum L.) cv. Sakha 93 plants. Experiments were conducted in the Experimental Farm of the Faculty of Agriculture, Menoufia University, Egypt, during two consecutive winter seasons. Pot experiments involved ten treatments with non-magnetized and magnetized water with various degrees of salinity. Plant samples were taken 95 days after sowing. Irrigation with magnetically treated seawater was found to have beneficial effects on plant growth, water relations, biochemical characteristics, and yield components compared with untreated plants. The germination of wheat seeds increased 13% when treated with magnetic seawater. On the yield scale, the spike length was increased by 40% in season one, and 82% in season two when compared to the control, while the weight of 100 grains increased by 148% and 171%, in each season, respectively, when treated with magnetic water. The anatomical leaf and stem parameters of the plants were markedly improved by watering with magnetically treated seawater at 10 dS m−1 compared to the control. However, the leaf water deficit, transpiration rate, and abscisic acid content in the plant shoots decreased significantly (p < 0.05). The use of magnetically treated seawater of up to 7.5 dS m−1, instead of tap water, is recommended due to benefits to germination and seedling parameters, growth, yield, and physiological, chemical, and anatomical characteristics. In conclusion, magnetic treatment of seawater improved germination performance, growth, and yield of wheat under saline conditions

A mean-field kinetic lattice gas model of electrochemical cells

We develop Electrochemical Mean-Field Kinetic Equations (EMFKE) to simulate electrochemical cells. We start from a microscopic lattice-gas model with charged particles, and build mean-field kinetic equations following the lines of earlier work for neutral particles. We include the Poisson equation to account for the influence of the electric field on ion migration, and oxido-reduction processes on the electrode surfaces to allow for growth and dissolution. We confirm the viability of our approach by simulating (i) the electrochemical equilibrium at flat electrodes, which displays the correct charged double-layer, (ii) the growth kinetics of one-dimensional electrochemical cells during growth and dissolution, and (iii) electrochemical dendrites in two dimensions.Comment: 14 pages twocolumn, 17 figure

A review of shrimp aquaculture and factors affecting the gut microbiome

Evolution of aquaculture is essential to supply the need and meet the demand for aquatic-based protein due to increasing global population and increased market demand. In the last decades, the shrimp sector has been considered one of the fastest growing aquaculture systems due to its economic significance. Growing efforts have been made to increase the production of cultivated shrimp through the development of aquaculture practises. However, in high-density shrimp farming, shrimp has been threatened by frequent diseases and several environmental stressors which results in significant variations in shrimp survival rates. Thus, understanding the driving environmental and managerial factors that affect shrimp health may support the global efforts for promoting sustainable shrimp aquaculture. A distinct intestinal microecosystem that the host’s microbiota can create is intimately linked to the host’s ability to survive, grow, and develop. The intestinal microbiota of shrimp is in a state of dynamic equilibrium under normal circumstances to preserve the intestine’s typical physiological functioning. Shrimp has high diversity and dynamic composition of gut microbiota including Proteobacteria, Bacteroidetes, and Actinobacteria. There is a high correlation between the development of shrimp intestinal microbiota and environmental changes and subsequently the health status of shrimp. This correlation seems to be highly plasticity, even over short-term timescales. The changes in aquaculture ecosystem across age, environment, diet, and diseases or the exposure to new habitat has a great impact on composition of shrimp microbiota. This review summarizes the methods of shrimp aquaculture and the impacts of ecological factors (e.g. dietary manipulation, age, physiological development, and other environmental factors) on gut microbiota composition as well as the intervention approaches to modulate the intestinal microbial composition
