Placement of infrastructure and other facilities underground brings superior opportunities for long-term improvements in terms the environmental impact urban areas more efficient use space. However, construction is a high-risk activity has been considered challenging problem geotechnical structural designers. Therefore, evaluation stability structures plays vital role design. This paper present...

An increasing number of railway tunnels are afflicted with tunnel lining diseases. Through on-site detection diseases in double-track tunnels, this paper analyzed its causative factors and developed a section steel arch frame reinforcement. simulation mechanical performance, both the plate concrete met tensile strength code requirements for design (TB 10003-2016). It effectively repaired damage...

The processing of single words that varied in their semantic (concrete/abstract word) and syntactic (content/function word) status was investigated under different task demands (semantic/ syntactic task) in an event-related functional magnetic resonance imaging experiment. Task demands to a large degree determined which subparts of the neuronal network supporting word processing were activated....

Underlying fabrics can change the appearance, function and quality of the garment, and also add so much longevity of the garment. Nowadays, with the increasing use of various types of fabrics in the garment industry, their resistance to bagging is of great importance with the aim of determining the effectiveness of textiles under various forces. The current paper investigated the effect of unde...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

In the New Austrian Tunneling Method (NATM) of tunnel design and construction, it is important to know actual compressive strength lining concrete at early ages, which determines time demolding its future durability. The degree hydration reaction in-place regarded as a useful reference estimate development concrete. Based on concept On-Site Visualization, this paper presents new approach monito...

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.

  The distribution and localization of acid and neutral mucins in various cells lining the olfactory epithelium of Cyprinus carpio have been studied histochemically by employing the PAS-AB technique. Variations in the localization of protein in different cells lining the olfactory epithelium have been correlated with the functional significance of the region concerned. Intense localization of t...

Million cubic meters from abandoned mines worldwide could be used as subsurface reservoirs for large scale energy storage systems, such adiabatic compressed air (A-CAES). In this paper, analytical and three-dimensional CFD numerical models have been conducted to analyze the thermodynamic performance of A-CAES in during charging discharging processes. Unlike other research works, which heat tran...
