The purpose of this paper is to study the impact of ISO 14001 and other significant factors on solid waste generation rates of organizations. The research is based on a survey conducted on a random sample of industrial companies that operate in United States. The paper reveals that companies’ solid waste generation rates are significantly reduced by certification and identifies several factors ...

On December 1, 2000, EPA adopted new source performance standards and emission guidelines for commercial and industrial solid waste incineration units established under Sections 111 and 129 of the Clean Air Act. In 2001, EPA granted a petition for reconsideration regarding the definitions of ‘‘commercial and industrial waste’’ and ‘‘commercial and industrial solid waste incineration unit.’’ In ...

The temperature dependence of optical absorptions in liquid Na is calculated. The electron energy values are obtained to second order in perturbation theory which are then used to determine the electron density of states. The density of states plots show some structure similar to those noted in the solid state. The optical conductivity in the liquid state is found to increase with the tem­ pera...

The electronic spectroscopy of oxygen atoms trapped in solid xenon are reported. Excitation of the solid between 220 and 260 nm leads to two main emissions centered at 3.35 and 1.65 eV, both of which arise from the same upper state. The excitations are assigned to chargetransfer absorptions in interstitial Oh sites; the emitting state, which has a lifetime of 227 ns, is assigned to Xe+O(‘xc+). ...

We demonstrate the existence of buried image-potential states at the interface between thick Ar films and a Cu(100) substrate. The electron dynamics of these solid-solid interface states, energetically located above the vacuum level in the band gaps of both materials, could be investigated with time-resolved two-photon photoemission for an Ar layer thickness up to 200 A. Relaxation on time scal...

We present an effective measurement scheme for the solid-state qubits that does not introduce extra decoherence to the qubits until the measurement is switched on by a resonant pulse. The resonant pulse then maximally entangles the qubit with the detector. The scheme has the feature of being projective, noiseless, and switchable. This method is illustrated on the superconducting persistent-curr...

An investigation of a series of seven angular "V" shaped NPIs (1-7) is presented. The effect of substitution of these structurally similar NPIs on their photophysical properties in the solution-state and the solid-state is presented and discussed in light of experimental and computational findings. Compounds 1-7 show negligible to intensely strong emission yields in their solid-state depending ...

Clusters of solid-state quantum devices have very long-lived metastable states of local energy minima which may be used to store quantum information. The strong power against decoherence with the great flexibility in state manipulation and system scaling up together should make solid-state devices very competitive in quantum computer engineering. PACS numbers: 89.80.+h, 03.65.Bz, 71.45.-d Types...
