the possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of wood-plastic novolac has been proved by using differential scanning calorimetry (dsc) and fourier transformed infra red (ft-ir) spectroscopy. synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. it was found that mechanical prope...

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...

Jam type product was successfully developed using cashew apple bagasse from juice manufacturing. Proximate analysis of carried out including soluble and insoluble fiber content. Cashew added to 3 different ratios produce jam products their sensory quality evaluated; 5 percentage content in favored all parameters. Physicochemical properties the were analyzed proximate composition, dietary conten...

Aggregation of Aβ peptides into amyloid plaques is considered to trigger the Alzheimer's disease (AD), however the mechanism behind the AD onset has remained elusive. It is assumed that the insoluble Aβ aggregates enhance oxidative stress (OS) by generating free radicals with the assistance of bound copper ions. The aim of our study was to establish the role of Met35 residue in the oxidation an...

Objective: The objective of this study is to establish the quality standards of Safoof-e-Muhazzil (SEMZ), a polyherbal Unani formulation for the treatment of overweight and obesity. Methods: The quality standards of SEMZ were established as per WHO guidelines including heavy metal residues, pesticides residue, aflatoxins, microbial load, GC-MS analysis and HPTLC fingerprinting analysis. Results...

Three-dimensional hierarchical Prussian blue composed of ultrathin nanosheets was successfully synthesized by employing a self-aggregation and oriented attachment strategy. The unique structure highly increases the exposure of micropores and metal sites of Prussian blue to guests, thus significantly enhancing its hetero-catalysis and adsorption properties compared to cubic and commercial counte...

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 ...

During the dormant period a series of five samples of the buds and of the preceding year's growth was taken from a number of dominant and codominant yellow poplar trees. The samples were dried in an oven at 650 C., and were then ground in a ball mill until the material would pass through a 100-mesh sieve. Duplicate samples of from 25 to 50 grams were taken from this large sample, covered with 8...
