This study aimed to evaluate genotypic variability in 30 vegetable amaranth genotypes for nutrient composition, antioxidant content, and 12 yield contributing traits. The trials were in the field of Bangabandhu Sheikh Mujibur Rahman Agricultural University in Bangladesh for consecutive two years (2012 and 2013) implementing Randomized Complete Block Design (RCBD) with three replications. High mean value, high range of variability and high genotypic variance were observed for all the traits except content of Ca, protein and betacarotenoid. Close differences between genotypic and phenotypic variances and genotypic and phenotypic coefficient of variations were observed for all the traits. Considering all genetic parameters, selection based on contents of potassium, manganese, and ascorbic acid, plant height, leaves/plant, diameter of stem base, fiber content, leaf area and foliage yield/plot seemed to be effective for the improvement of vegetable amaranth. Foliage yield had significant positive correlation with plant height, leaves per plant, diameter of stem base, fiber content and leaf area. Nutrient content and antioxidant traits exhibited interesting results, i.e., had insignificant genotypic correlations with foliage yield and most of the studied traits indicating that selection with these traits might be possible without compromising any yield loss. Therefore, concomitant selection for high nutrient, antioxidant and high foliage yield would be effective for improvement of the vegetable amaranth. Based on mean, range, genetic parameters, correlation coefficient and path coefficient values, direct selection through three traits, i.e., fiber content, leaf area and diameter of stem base would significantly improve the foliage yield of vegetable amaranth. On the other hand, concomitant selection based on high nutrient and antioxidant content and high foliage yield would be effective selection method for improvement of vegetable amaranth. © 2014, World Food Ltd. and WFL Publishers.

We report a search for the charmless hadronic decay B0→ηπ0 with a data sample corresponding to an integrated luminosity of 694 fb-1 containing 753×106 BB¯ pairs. The data were collected by the Belle experiment running on the Y(4S) resonance at the KEKB e+e- collider. We measure a branching fraction B(B0→ηπ0)=(4.1-1.5-0.7+1.7+0.5)×10-7, where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of B(B0→ηπ0)<6.5×10-7 at 90% confidence level. The signal has a significance of 3.0 standard deviations and constitutes the first evidence for this decay mode. © 2015 American Physical Society. © 2015 American Physical Society.

Drying Technology | Year: 2015
An innovative technology for sewage treatment systems is proposed. A mixture of sewage sludge and char particle is subjected to drying in the progress of composting in an updraft column. Exothermic heat generated during composting is utilized for energy of sludge drying. The char particle in the mixture contributes to enhancement of composting and drying rate. This study presents drying and composting behaviors of sludge to examine the effect of char addition. A fundamental drying experiment was carried out by hot-air heating of the sample in a small vessel. The drying characteristic curve for a mixture of sludge and char was greater than the sample of only sludge over a whole period if the drying rates were compared with the same moisture content. The drying behavior could be analyzed with a reasonable agreement by the water front receding model. The enhancement effect of drying and composting of sludge by char addition was confirmed by examination using a pilot scale of the updraft column whose volume was 50 m3. Sludge with 400% dry base (80% wet base) in moisture content could be dried successfully to lower moisture content than 67% dry base (40% wet base) only by exothermic heat during composting without supplying any auxiliary energy from the outside, and the treatment time was reduced by mixing char in sludge. The behavior was analyzed with a satisfactory agreement by a theoretical model employing moisture diffusion parameters determined from the drying characteristic curve. © 2015, Copyright © Taylor & Francis Group, LLC.
