Symmetry analysis of the Klein-Gordon equation in Bianchi i spacetimes
(
World Scientific
, 2015 , Article)
In this work we perform the symmetry classification of the Klein-Gordon equation in Bianchi I spacetime. We apply a geometric method which relates the Lie symmetries of the Klein-Gordon equation with the conformal algebra ...
Approximate methods for optimal replacement, maintenance, and inspection policies
(
Elsevier
, 2015 , Article)
It might be difficult sometimes to derive theoretical and numerical solutions for analytical maintenance modelings due to the computational complexity. This paper takes up several approximate models in maintenance theory, ...
Susceptibility of Agrotis segetum (noctuidae) to Bacillus thuringiensis and analysis of midgut proteinases
(
Taylor & Francis
, 2015 , Article)
Seventy-eight Bacillus thuringiensis isolates were selected for a screening against the Lepidoptera species Agrotis segetum to search the higher insecticidal activity. In a preliminary bioassay, the spore-crystal mixture ...
Characterisation of novel Bacillus thuringiensis isolates against Aedes aegypti (Diptera: Culicidae) and Ceratitis capitata (Diptera:Tephridae)
(
Elsevier Inc.
, 2015 , Article)
Bacillus thuringiensis is successfully used in pest management strategies as an eco-friendly bioinsecticide. Isolation and identification of new strains with a wide variety of target pests is an ever growing field. In this ...
Effects of the P20 protein from Bacillus thuringiensis israelensis on insecticidal crystal protein Cry4Ba
(
Elsevier B.V.
, 2015 , Article)
The accessory protein P20 from Bacillus thuringiensis israelensis has been defined as an important molecular chaperone for forming crystal Cyt1Aa, and enhancing Cry11Aa and Cry4Aa expression. To investigate its putative ...
Corporate governance voluntary disclosures in developing countries: evidence from Jordanian banks
(
Inderscience
, 2015 , Article)
The main objective of the current study is to determine the corporate governance mechanisms and company’s characteristics that effect on the level of voluntary disclosure provided by Jordanian banking listed companies; it ...
Identity issues: expatriate professors teaching and researching in Qatar
(
Springer Netherlands
, 2015 , Article)
Today, academics are more transient, working outside their home countries,
than at any other time in the history of academics especially in the Arab World were there
is great demand for faculty members educated in Western’ ...
An adaptive step-down procedure for fault variable identification
(
Taylor & Francis
, 2015 , Article)
In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ...
Multiple parts process planning in serial–parallel flexible flow lines: part II—solution method based on genetic algorithms with fixed- and variable-length chromosomes
(
Springer London
, 2015 , Article)
Multiple parts process planning (MPPP) is a hard optimization problem that requires the rigor and intensity of metaheuristic-based algorithms such as simulated annealing and genetic algorithms. In this paper, a solution ...
Structural and morphological study of mechanochemically synthesized crystalline nanoneedles of Zr-doped carbonated chlorapatite
(
Elsevier B.V.
, 2015 , Article)
Nanosize Zr-doped carbonated chlorapatite (n-ZCCA) was developed as a novel bioceramic by a ball milling process. Results showed that the microstructural characteristics of the product were affected significantly by the ...
