The existing recycling chain of construction and demolition waste generally considers soil inert solid to be sent landfills. As the most significant component C&D (construction demolition) waste, excavated occupies approximately half Currently, is a big issue in China’s Pearl River Delta. This paper investigated composition quantity Shenzhen, China. In particular, potential market demand fo...

The current situation in Russia, the United States, the Middle East and many other countries, clearly highlights the problem of the war against terrorism. Today’s terrorism is neither desperate nor isolated. In Russia it is amply financed, well led and efficiently organized into battalions, companies, platoons and squads. The terrorist organization here in Russia includes all the essential mili...

A general discussion is given for first-kind (FK) and quantum non-demolition (QND) measurements. The general conditions for these measurements are derived, including the most general one (called the weak condition), an intermediate one, and the strongest one. The weak condition indicates that we can realize a FK or QND measuring apparatus of wide classes of observables by allowing the apparatus...

THE LISTER WARD AND LISTER'S CENTENARY. Although the managers of the Glasgow Royal Infirmary, as we noted in our November issue, have decided to destroy the famous Lister Ward, and it is understood that tenders have actually been accepted for its demolition, Mr. James A. Morris, F.R.I.B.A., has followed his admirable " Humble Plea " for its retention with another pamphlet, believing that at the...

Assuming an average latency of 42 years, the authors predict that incidence rates will peak in 2009 and that diagnoses will peak in 2014. However, they caution that ongoing use of chrysotile asbestos (which has been implicated but not conclusively established as a cause of mesothelioma) and the release of asbestos fibers from older buildings during demolition or reno­ vation may slow the projec...

universal quantum computation optical QIP, efficient resources In this letter we investigate the linear and nonlinear models of optical quantum computation and discuss their scalability and efficiency. We show how there are significantly different scaling properties in single photon computation when weak cross-Kerr nonlinearities are allowed to supplement the usual linear optical set. In partic...

We establish that the information which can be obtained in the measurement of a single system about the unknown quantum wavefunction of the system is limited to estimates of the expectation values of the measured observables, with the estimate errors satisfying the uncertainty principle. Only the fully apriori known wavefunction could be determined exactly. We consider specifically measurement ...

The paper discusses operations aimed at creating a safer natural or man made rock slope by artificially inducing the displacement of unstable elements by blasting. A detailed analysis of the problems with the use of explosives present when conducting these activities is carried out focusing on the advantages and disadvantages of this technology. The results of two examples of demolition of inst...
