Comparison of adsorption of mercaptopropyltrimethoxysilane on amphiphilic TiO 2 and hydroxylated SiO 2
(2010)Alkylsilane 3-mercaptopropyltrimethoxysilane (3MPT) monolayers with a functional end group -SH were used to immobilize Ag colloidal nanoparticles on photoinduced amphiphilic TiO 2 and hydroxylated SiO 2 surfaces. The ... -
Risky tax shields and risky debt: An exploratory study
(2010)This article (1) identifies three sources of risk for tax shields (TS): Two of them are associated with debt risk and one is associated with operating risk. (2) A set of conditions for defining risky debt associated with ... -
Technology and market conditions toward a new competitive landscape in the wireless access market
(2010)This article argues that the wireless telecommunication market is about to witness a shift in business models and market structure as a result of the deployment of new broadband access technologies, spectrum management ... -
Prediction of RFID performance in supply chains
(2010)This paper discusses the challenges to wide-spread radio frequency identification (RFID) adoption in supply chains using the technology s-curve and the concept of buying hierarchy. A survey on RFID uptake in New Zealand ... -
Organizational management for innovation: Petrochemical sector case in Cartagena de Indias (Colombia)
(2010)This study was made within the framework of characterizing the petrochemical and plastic sector and aims to analyze different models of organizational management for innovation. The methodology used was that of multiple ... -
Analytical solution to the circularity problem in the discounted cash flow valuation framework
(2011)In this paper we propose an analytical solution to the circularity problem between value and cost of capital. Our solution is derived starting from a central principle of finance that relates value today to value, cash ... -
How evolving network access and network management technologies are redefining the competitive wireless markets

Robot based on task-space dynamical model
(2011)This study deals with the dynamic modelling and task space control of the Stewart-Gough platform. The dynamic equations were obtained using the virtual work approach, and include all the 13 presented in the platform, that ... -
Viable business models for M-commerce: The key components
(IGI Global, 2011)As mobile applications increase in popularity, the issue of how to build viable business models for the m-commerce industry is becoming a clear priority for both organizations and researchers. In order to address this ... -
Electromagnetic sources distributed on shells in a Schwarzschild background
(2011)In the Introduction we briefly recall our previous results on stationary electromagnetic fields on black hole backgrounds and the use of spin-weighted spherical harmonics. We then discuss static electric and magnetic test ... -
Design of a CMG for underwater robots
(2011)In this paper we present a Control Moment Gyroscope (CMG) for underwater robots. This is a single gimbal CMG with pyramid type configuration. This device has a modular design and is self-contained (i.e., all mechanical and ... -
Steric and chain length effects in the (√(3) × √(3))R30° structures of alkanethiol self-assembled monolayers on Au(111)
(Wiley-VCH Verlag, 2011)The translational and orientational potential energy surfaces (PESs) of n-alkanethiols with up to four carbon atoms are studied for (√(3) × √(3))R30° self-assembled monolayers (SAMs). The PESs indicate that methanethiol ... -
Monopole and dipole layers in curved spacetimes: Formalism and examples
(2011)The discontinuities of electromagnetic test fields generated by general layers of electric and magnetic monopoles and dipoles are investigated in general curved spacetimes. The equivalence of electric currents and magnetic ... -
