Evaluation of the convolution sums Sigma(l+27m=n) sigma(l)sigma(m) and Sigma(l+32m=n) sigma(l)sigma(m)
(World Scientific Publ Co Pte Ltd, 2016)
We determine the convolution sums Sigma(l+27m= n) sigma(l)sigma(m) and Sigma(l+32m= n) sigma(l)sigma(m) for all positive integers n. We then use these evaluations together with known evaluations of other convolution sums ...
Purification and characterization of a polyphenol oxidase from cimin grape (Vitis vinifera spp., Cimin)
(Research Journal Biotechnology, 2016)
A polyphenol oxidase (PPO) from Cimin grape was purified 11.2-fold by using a Sepharose 4B-L-tyrosine-p-aminobenzoic acid affinity column. the optimum pH and temperature of PPO purified from Cimin grape were 7.5 and 30 ...

The aim of the study is to determine the changes of steppe flora at upper Mesopotamia according to seasons. Depending on the blooming phenophase of the plants picked from the research area, the seasonal conditions of the ...
Determination of the local structure of CsBi4-xPbxTe6 (x=0, 0.5) by X-ray absorption spectroscopy
(Royal Soc Chemistry, 2016)
We have studied the local structure and valence electronic unoccupied states of thermoelectric CsBi4Te6 and superconducting CsBi3.5Pb0.5Te6 (T-c similar to 3 K) by extended X-ray absorption fine structure (EXAFS) and X-ray ...
Improving the stability of solar cells using metal-organic frameworks
(Royal Soc Chemistry, 2016)
Although Cu2S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS ...
A study of temperature dependent local atomic displacements in a Ba(Fe1-xCox)(2)As-2 superconductor
(Royal Soc Chemistry, 2016)
We have studied the local structure of a Ba(Fe1-xCox)(2)As-2 superconductor using temperature dependent extended X-ray absorption fine structure (EXAFS) measurements. Polarized EXAFS at the Fe K-edge on an optimally doped ...
