Tissue localizations of cytosolic glutamine synthetase (GS1; EC 6.3.1.2), chloroplastic GS (GS2), and ferredoxin-dependent glutamate synthase (Fd-GOGAT; EC 1.4.7.1) in rice (Oryza sativa L.) leaf blades were investigated using a tissue-print immunoblot method with specific antibodies. The cross-sections of mature and senescent leaf blades from middle and basal regions were used for tissue print...

Leaf protein can be obtained cost-efficiently by alkaline extraction, but overuse of chemicals and low quality of (denatured) protein limits its application. The research objective was to investigate how alkali aids protein extraction of green tea leaf residue, and use these results for further improvements in alkaline protein biorefinery. Protein extraction yield was studied for correlation to...

The antioxidant activity of Annona squamosa (A. squamosa) leaf was carried out using methanol extract and fractionated namely n-hexane, ethyl acetate residue. performed the 1-diphenyl-2-Pycrilhydrazil (DPPH) method. test residue yielded IC50 6.87, 169.99, 31.55 44.75 ppm. fraction with ppm by column chromatography silica gel G60 as stationary phase n-hexane: mobile phase. results obtained 181 f...

in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline a...

in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

The toric residue is a map depending on n + 1 semi-ample divisors on a complete toric variety of dimension n . It appears in a variety of contexts such as sparse polynomial systems, mirror symmetry, and GKZ hypergeometric functions. In this paper we investigate the problem of finding an explicit element whose toric residue is equal to one. Such an element is shown to exist if and only if the as...

It is shown that the extended quadratic residue code of length 20 over GF(7) is a unique self-dual [20, 10, 9] code C such that the lattice obtained from C by Construction A is isomorphic to the 20-dimensional unimodular lattice D 20, up to equivalence. This is done by converting the classification of such self-dual codes to that of skew-Hadamard matrices of order 20.

The largest minimum weight of a self-dual doubly-even binary (n, k, d) code is d = 4bn/24c+ 4. Of such codes with length divisible by 24, the Golay Code is the only (24, 12, 8) code, the Extended Quadratic Residue Code is the only known (48, 24, 12) code, and there is no known (72, 36, 16) code. One may partition the search for a (48, 24, 12) self-dual doubly-even code into 3 cases. A previous ...

The rice–ratoon rice cropping system has the advantages of saving labor and imparting economic benefits. Optimizing tillage straw management is beneficial for improving ratoon growth yield. In this study, field experiments were conducted to examine effects four managements on yield a in central China 2020 2021. included no-till with main-season ratoon-season residues retained soil’s surface (NT...

ABSTRACT The aim of this work was to increase the aerial part, biometry, and yield achenes from sunflower plants on effect increasing doses blood residue, as an alternative source phosphorus (P), in a clayey-textured red Oxisol. experimental design used randomized blocks, with six treatments four replications. consisted five residue (0, 6, 12, 24 48m3 ha-1) control treatment that received phosp...
