Background In recent years, the study of molecular basis of uptake, transport and utilization of grain Fe/Zn (GFe/GZn) in wheat has been an active area of research. As a result, it has been shown that a number of transporters are involved in uptake and transport of Fe. In a recent study, knockout of a transporter gene OsVMT (VACUOLAR MUGINEIC ACID TRANSPORTER) in rice was shown to be involved in Fe homoeostasis. Objective In this study, we analysed VMT genes among six monocots and three dicots with major emphasis on wheat VMT genes (TaVMTs), taking OsVMT gene as a reference. Methods and results Using OsVMT gene as a reference, VMT genes were identified and sequence similarities were examined among six monocots and three dicots. Each VMT protein carried one functional domain and 7 to 10 distinct motifs (including 9 novel motifs). The qRT-PCR analysis showed differential expression by all the six TaVMT genes in pairs of contrasting wheat genotypes with high (FAR4 and WB02) and low (K8027 and HD3226) GFe/GZn at two different grain filling stages (14 DAA and 28 DAA). TaVMT1 genes showed up-regulation in high GFe/Zn genotypes relative to low GFe/Zn genotypes, whereas the TaVMT2 genes showed down-regulation or nonsignificant up-regulation in a few cases. Conclusions At 14 DAA, each of the six TaVMT genes exhibited higher expression in wheat genotypes with high GFe and GZn relative to those with low GFe and GZn, suggesting major role of VMT genes in improvement of grain Fe/Zn homoeostasis, thus making TaVMT genes useful for improvement in Fe/Zn in wheat grains.

The lead sulfide (PbS) thin films were deposited on glass substrate using successive ionic layer adsorption and reaction (SILAR) method at different pH of the cationic precursor, keeping the pH of the anionic precursor invariant. In this work, we establish that the pH of the cationic precursor and in turn the size of the crystallites affects the optical and electrical properties of PbS thin films. The characterization of the film was carried out using X-ray diffraction, scanning electron microscopy, optical and electrical measurement techniques. The presence of nanocrystallites was revealed by optical absorption and structural measurements. The PbS thin films obtained under optimal deposition conditions were found to be polycrystalline with face centered cubic structure. The lattice parameter, grain size, micro strain,average internal stress and dislocation density in the film were calculated and correlated with pH of the solution. The values of average crystallite size were found to be in the range 16e23 nm. Optical studies revealed the existence of direct and indirect band gap values in the range 0.99e1.84 eV and 0.60e0.92 eV, respectively. The room temperature resistivity of the synthesized PbS films was in the range of 1.2 ×107 to 3.5×107Ω cm.

This paper proposes new criteria to fix hidden neuron in Multilayer Perceptron Networks for wind speed prediction in renewable energy systems. To fix hidden neurons, 101 various criteria are examined based on the estimated mean squared error. The results show that proposed approach performs better in terms of testing mean squared errors. The convergence analysis is performed for the various proposed criteria. Mean squared error is used as an indicator for fixing neuron in hidden layer. The proposed criteria find solution to fix hidden neuron in neural networks. This approach is effective, accurate with minimal error than other approaches. The significance of increasing the number of hidden neurons in multilayer perceptron network is also analyzed using these criteria. To verify the effectiveness of the proposed method, simulations were conducted on real time wind data. Simulations infer that with minimum mean squared error the proposed approach can be used for wind speed prediction in renewable energy systems.

The Brassicaceae family contains a wide range of horticultural crops that constitute a major part of diets worldwide. The aim of this study was to investigate the total phenolic content and antioxidant activity of some Brassicaceae sprouts (red radish, red kohlrabi, pink and red cabbage, tatsoi, and broccoli) and their commercial vegetables. The results showed that the ethanol extracts of the sprouts exhibited higher total phenolic and flavonoid contents and antioxidant activities than those of the commercial vegetables, with the exception of tatsoi. Among the sprouts, broccoli (25.75 mg GAE/g extract) and tatsoi (6.522 mg GAE/g extract) showed the highest and lowest total phenolic contents, respectively. In regards to commercial vegetables, tatsoi contained the highest total phenolic (31.511 mg GAE/g extract) and flavonoid (15.845 mg catechin/g extract) contents. For the antioxidant activity of sprouts, red radish showed the highest 1,1-diphenyl-2-picryl hydrazyl (DPPH) (IC50 of 358 μg/mL) and 2,2'‐azinobis (3‐ethylbenzothiozoline‐6‐sulfonic acid) diammonium salt (ABTS) (IC50 of 413 μg/mL) scavenging activities among all sprouts. For vegetables, red cabbage e xhibited t he h ighest D PPH ( IC50 of 615 μg/mL) and ABTS (578 μg/mL) radical scavenging activities among all vegetables. We observed the lowest DPPH and ABTS activities in pink cabbage vegetables, with IC50 values of 8,989 and 8,304 μg/mL, respectively. The findings of this study suggest that the tested Brassicaceae sprouts are a good dietary source of phenolic compounds with appreciable antioxidant potential.

In India, continuous production of electricity and sweet/potable water from Solar power and desalination plant plays a major role in the industries. Particularly in Copper industry, Solar power adopts Solar field collector combined with thermal storage system and steam Boiler, Turbine & Generator (BTG) for electricity production and desalination plant adopts Reverse osmosis (RO) for sweet/potable water production which cannot be used for long hours of power generation and consistency of energy supply for industrial processes and power generation cannot be ensured. This paper presents an overview of enhanced technology for Solar power and Desalination plant for Copper industry making it continuous production of electricity and sweet/potable water. The conventional technology can be replaced with this proposed technique in the existing and upcoming industries.

Objective This study aimed to examine the association between maternal pre-pregnancy underweight and the risk of small-for-gestational-age (SGA) birth among Asian Americans compared with non-Hispanic (NH) whites. Methods Using 2014-2018 birth data, we categorized maternal underweight and SGA according to severity. Bivariate analyses were performed to examine the demographics and maternal body mass index (BMI). Adjusted logistic regression models were used to analyze the association between maternal BMI and SGA among Asian Americans compared with NH-Whites. Results In Asian Americans, the likelihood of SGA birth was higher among underweight mothers than among mothers with a normal BMI (odds ratio [OR], 1.37; 95% confidence interval [CI], 1.30-1.46). We observed that as the severity of maternal underweight increased, the adjusted odds of SGA increased. Underweight Asian American mothers were more likely to give birth to SGA infants than underweight NH-White mothers (OR, 1.36; 95% CI, 1.28-1.44). Conclusion This study shows the association between maternal underweight and SGA birth among Asian Americans, supporting the development of culture-sensitive interventions addressing the impact of weight on pregnancy.
