In recent years, the Lamb wave analysis by the multi-channel analysis of surface waves (MASW) for concrete structures has been an effective nondestructive evaluation, such as the condition assessment and dimension identification by the elastic wave velocities and their reflections from boundaries. This study proposes an effective Lamb wave analysis by the practical application of MASW to concre...

We analyze the concrete security provided by a signature scheme described in a recent Internet Draft by McGrew and Curcio.

We have compiled contemporaneous broadband observations of the black hole candidate X-ray binary GX 339 4 when in the low/hard X-ray state in 1981 and 1997. The data clearly reveal the presence of two spectral components, with thermal and nonthermal spectra, overlapping in the optical–near-infrared bands. The nonthermal component lies on an extrapolation of the radio spectrum of the source, and...

This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...

doi:10.1160/TH11-03-0150 Thromb Haemost 2011; 106: 554 Dear Sirs, In the recently published work from Adam Nowakowski et al. “Megakaryocyte gene targeting mediated by restricted expression of recombinase Cre” (Thromb Haemost 2011; 105.1) the authors present a transgenic mouse strain that allows Cre expression under the control of the alphaIIb promoter (1). Nowakowski et al. (1) suggest that thi...

This article discusses ideas for a new literacy compact in Australia that would encompass multilingual, language revitalizing, and Indigenous grounded perspectives. A key question posed is whether uniquely Australian order can be imagined, one extend the historically inherited tradition of Western grammar–centred practices as conventionally typified print-based English book letter reading its d...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...

Surfaces of carbon fibre roving were modified by means of a low temperature plasma treatment to improve their bonding with mineral fines; the latter serving as an inorganic fibre coating for the improved mechanical performance of carbon reinforcement in concrete matrices. Variation of the plasma conditions, such as gas composition and treatment time, was accomplished to establish polar groups o...
