Abstract Novel charge transfer complexes have been formed in the reaction of the interesting powerful electron donor 1,4,7,10,13,16-hexamethyl-1,4,7,10,13,16-hexaazacyclooctadecane (HMHACOD) with σ-electron acceptor iodine ...
Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology
(
Elsevier B.V.
, 2011 , Article)
Statistical experimental designs, involving a Plackett-Burman design followed by a rotatable central composite design were used to optimize the culture medium constituents for Bacillus thuringiensis bioinsecticide production. ...

The Arab C is a member of the Jurassic Arab Formation, one of the largest carbonate reservoirs in the Arabian Basin. Detailed petrographic analysis of cores and thin sections from selected wells in the onshore Dukhan ...
Use of post-stratification in composite sampling for estimating mean
(
Springer
, 2011 , Article)
We show with the results of a study conducted in the Hamadan Province, Iran as to how the use of composite sampling for estimating mean zinc concentration in the soil can help reduce analytical costs by reducing the number ...
Empirical likelihood inference for population quantiles with unbalanced ranked set samples
(
Taylor & Francis Group
, 2011 , Article)
We consider nonparametric interval estimation for the population quantiles based on unbalanced ranked set samples. We derived the large sample distribution of the empirical log likelihood ratio statistic for the quantiles. ...
Edge-maximal graphs without θ 7 -graphs

AEgIS (Antimatter experiment: gravity, interferometry, spectroscopy) is an experiment approved by CERN with the goal of studying antihydrogen physics. In AEgIS, antihydrogen will be produced by charge exchange reactions ...
On the boundedness of rough oscillatory singular integrals on Triebel-Lizorkin spaces
(
springer link
, 2011 , Article)
We obtain appropriate sharp bounds on Triebel-Lizorkin spaces for rough oscillatory integrals with polynomial phase. By using these bounds and using an extrapolation argument we obtain some new and previously known results ...
