A decoupling technique for simulating near-field wave motions in two-phase media is introduced in this paper, which includes lumped-mass FEm, explicit integration procedures and local artificial boundary condition. The decoupling feature of this method reduce s the implicit solution of a set of coupling algebraic equations to a successive explicit solution of the individual equations, and substantially reduces the computational cost, which renders the technique particularly suitable to cope with problems of near-field wave motion. First, An equivalent but direct weighted residual method is presented to solve boundary value problems in this paper, that is to apply the Green's theorem for integration by parts on the equivalent integral statement of the field contr ol equations, then introduce the Neumann conditions into directly. Using this method and considering the precision requirement in wave motion simulation, a lumped -mass FEm for two-phase media with clear physical concepts and convenience in employment is de rived. Then, considering the innate attenuation character of the wave in two -phase media, an attenuation parameter is introduced into mTF to simulating the attenuate outgoing wave in two-phase media. At last, two numerical experiments are presented, and the numerical results are compared with the analytical ones , which demonstrate that the lumped-mass FEm and the modified mTF introduced in this paper have good precision.

Background: The new 5G telecommunication technology has stirred concerns about potential negative effects on human health by radiofrequency electromagnetic fields. As to whether skin biology can be affected by 5G waves has remained an unsolved challenge despite recent studies dealing with this issue. In particular, a strategy for rational design of an assay allowing to 1) reproducibly evaluate and decipher the 5G effects on skin as well as 2) test the potential protective effects of cosmetic active ingredients, has yet to be found. Here we describe an in vitro model of human normal keratinocytes irradiated by 5G waves and show their impact on two biomarkers of inflammatory stress, i.e. interleukin-1β (IL-1β) and reactive oxygen species (ROS) production. In addition, the capacity of a tannin-rich plant extract to protect against 5G impact is evaluated. materials and methods: In the first series of experiments, monolayers of human normal keratinocytes were irradiated or not (control) by 5G waves (3.5 mHz. in an anechoic chamber and were incubated at 37˚C for 24 hours. At the end of the incubation period, extracellular IL-1β and intracellular ROS were quantified using specific ELISA and colorimetric assays, respectively. In the second series of experiments, the effect of an overnight pre-incubation with increasing concentrations of a tannin-rich plant extract was evaluated. Additionally, we studied in a prospective way the expression of a set of 88 genes selected for their relevance to keratinocyte homeostasis, in relation to the 5G challenge as well as the protective effect of a tannin-rich plant extract. Results: 5G waves significantly increased IL-1β production by 48.4% (p β and ROS production. Finally, the expression of 47 genes was modified by 5G waves and/or by the tannin-rich plant extract. Conclusion: This is to our knowledge the first evaluation of the impact of 5G technology on inflammatory biomarkers of human normal skin cells. Here we provide an innova

Catalytic decomposition of methane with the addition of sulfur was used to synthesiz. unique single-walled carbon nanotubes (SWNTs), double-walled carbon nanotubes (DWNTs), and their aligned long ropes. High-resolution transmission electron microscopy (HRTEm) and laser Raman resonance spectroscopy were employed to study the structure and diameter distribution of these carbon nanotubes (CNTs). HRTEm observations show that, with

The undulation and characteristics of the Lehmann discontinuity at the base of the Low Velocity z.ne in the upper mantle are significant for understanding the coupling between the lithosphere and asthenosphere, and corresponding geodynamic processes. Vertical waveform data from six earthquakes with focal depths between 75 and 150 km and magnitudes mb 5.0–6.0 since 2004 were collected from the short-period Hi-net array. Selected waveform data were processed for each event network pair using the Nth-root slant stack method to retrieve the SdP conversion phases from the possible 220 km(Lehmann) discontinuity. The conversion points related to the SdP phases show that there is a clear and flat velocity interface around 230 km, suggesting that there is a sinking of the Lehmann discontinuity beneath Tonga with no obvious undulation. The 230 km depth of the Lehmann discontinuity in this location could be explained by an hypothesis of transition in the deformation mechanism from dislocation creep to diffusion creep.
