Investigation of Ecological Protection Plan for Deep Water Port City - Taking the Development Plan Investigation of Ningbo Meishan Island for an Example
Deep Water Port Ecological Protection Plan Port City
2011/12/16
Deep water coastline and ecological environment are natural resources that the development of port city will depend on. Driven by economy globalization, port city development is the inevitable choice ...
Investigation of Large LGB Detectors for Antineutrino Detection
thermal neutron detection, capture-gated neutron spectrometry
2011/9/9
A detector material or configuration that can provide an unambiguous indication of neutron capture can substantially reduce random coincidence backgrounds in antineutrino detection and capture-gated n...
An Investigation on the Basic Conceptual Foundations of Quantum Mechanics by Using the Clifford Algebra
Clifford algebra, foundations of quantum mechanics, wave function collapse,quantum mechanics and conceptual entities, von Neumann postulates on quantum measurement
2011/9/2
We review our approach to quantum mechanics adding also some new interesting results. We start by giving proof of two important theorems ms on the existence of the A(Si) and i,±1 N Clifford algebras. ...
Field Investigation and Wind-Environment Numerical Simulation of Cable-Stayed Bridge Site in the West Midlands Region
Cable-Stayed Bridge Field Investigation Numerical Simulation West Midlands Region Wind Environment
2011/12/16
The area of mountain ridge accounts for the most part of our country land. With the development of economic construction, more and more long span bridges have been built in the mountainous region of t...
Microcalorimetric investigation of water vapor adsorption on silica gel
Microcalorimetry Diffusivity Silica gel–water pair Heat of adsorption
2011/11/10
Water vapor adsorption on silica gel was investigated using Tian–Calvet-type microcalorimetry. Differential heat of adsorption data was obtained. The setup of microcalorimetry was used volumetric syst...
Experimental investigation on partially coherent higher-order non-diffractive beams
physical optics higher-order non-diffractive Bessel beam axicon partially coherence
2013/7/3
We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axicon. The investigation results show that when the partially ...
Soot microphysical effects on liquid clouds, a multi-model investigation
carbonaceous aerosols liquid clouds a multi-model investigation
2011/2/25
We use global models to explore the microphysical effects of carbonaceous aerosols on liquid clouds. Although absorption of solar radiation by soot warms the atmosphere, soot may cause climate cooling...
Modelling multi-phase halogen chemistry in the coastal marine boundary layer: investigation of the relative importance of local chemistry vs. long-range transport
multi-phase halogen chemistry the coastal marine boundary layer local chemistry long-range transport
2011/2/25
Measurements of significant concentrations of IO, I2 and BrO in a semi-polluted coast environment at Roscoff, in North-West France, have been made as part of the Reactive Halogens in the Marine Bounda...

With the development of society and economy, the issues of environment have becoming the focus of all around the world, especially in the developing countries. In China, on one hand, villagers' income...
A Computational and Theoretical Investigation of the Accuracy of Quasicontinuum Methods
quasicontinuum error analysis atomistic-to-continuum multiphysics.
2011/3/1
We give computational results to study the accuracy of several quasicontinuum methods
for two benchmark problems — the stability of a Lomer dislocation pair under shear and the
stability of a lattic...
An investigation into the MOPED data compression algorithm
