An alternative proof of Lie’s linearization theorem using a new λ-symmetry criterion
(
Elsevier
, 2015 , Article)
An alternative proof of Lie’s approach for the linearization of scalar second-order ordinary differential equations is derived by using the relationship between λ-symmetries and first integrals. This relation further leads ...
Ferromagnetic effects for nanofluid venture through composite permeable stenosed arteries with different nanosize particles
(
American Institute of Physics
, 2015 , Article)
In the present article ferromagnetic field effects for copper nanoparticles for blood flow through composite permeable stenosed arteries is discussed. The copper nanoparticles for the blood flow with water as base fluid ...
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, ...
Speaker identification using multimodal neural networks and wavelet analysis
(
Institution of Engineering and Technology
, 2015 , Article)
The rapid momentum of the technology progress in the recent years has led to a tremendous rise in the use of biometric authentication systems. The objective of this research is to investigate the problem of identifying a ...
Artisanal fishing of spiny lobsters with gillnets — A significant anthropic impact on tropical reef ecosystem
(2015 , Article)
Artisanal fishing activity with gillnets to capture the spiny lobster is a common practice along the coastal reefs of Brazil. This research aims to understand the impact that this artisanal fishing practice is having on ...
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 ...
Impacts of urbanization on the distribution of heavy metals in soils along the Huangpu River, the drinking water source for Shanghai
(
Springer Berlin Heidelberg
, 2015 , Article)
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections ...
K-shell photoionization of O+ and O2+ ions: Experiment and theory
(
American Physical Society
, 2015 , Article)
Absolute cross sections for the single and double K-shell photoionization of carbon like O2+ and nitrogen like O+ ions were measured in the 526–620-eV photon energy range by employing the ion-photon merged-beam technique ...
