REMARKS on BIANCHI SUMS and PONTRJAGIN CLASSES
(Cambridge University Press, 2014)
We use the exterior and composition products of double forms together with the alternating operator to reformulate Pontrjagin classes and all Pontrjagin numbers in terms of the Riemannian curvature. We show that the ...
Autism-relevant social abnormalities in mice exposed perinatally to extremely low frequency electromagnetic fields
(Elsevier Ltd, 2014)
The incidence of autism spectrum disorders (ASD) has been rising, but the causes of ASD remain largely unidentified. Collective data have implicated the increased human exposure to electromagnetic fields (EMF) in the ...
Efficiency and risk in commercial banking: empirical evidence from East Asian countries
This paper analyses the effects of off-balance sheet (OBS) activities and various types of risks on the cost and profit efficiencies of banks in seven East Asian countries between 2001 and 2008. Cost and profit efficiency ...

(ARRAY Development (Canada) Inc., 2014)
This paper reviews the existing literature and studies on the impact of Information Systems (IS) on the adoption of Internet Banking (IB). We reviewed the adoption theories utilized in IB studies within different contexts ...
Structural, optical and magnetic characterizations of Mn-doped MgO nanoparticles
Structural, optical and room temperature magnetic properties of Mn-doped MgO nanoparticles with Mn fractions (5-50 at.%), were investigated. The as-prepared pure MgO, with grain size of about 15 nm, exhibits two magnetization ...
Co-Doped ZnO nanoparticles: Structural, morphological, optical, magnetic and antibacterial studies
(Chinese Society of Metals, 2014)
Un-doped and Co-doped ZnO nanoparticles (NPs) with different weight ratios (0.5, 1.0, 1.5, and 2.0wt% of Co) were synthesized by a facile and rapid microwave-assisted combustion method using urea as a fuel. The prepared ...
The nature and components of perceived behavioural control as an element of theory of planned behaviour
Ajzen (1991. The theory of planned behaviour. Organizational Behaviour and Human Decision Processes, 50 (2), 179-211) suggested three constructs that determine the user's intention: attitude, subject norms and perceived ...
