Fires in steel construction, especially welding joints, cause damage, changes crystal structure, and mechanical properties of the material. Another effect fires, material undergoes rapid cooling due to extinguishing using water. This research aims simulate fires on ASTM A36 analyze impact fires. The method this is perform GMAW with heat treatment at 400 °C unti 700 results are form hardness lev...
We report on XMM-Newton spectroscopic observations of the luminous radio-quiet quasar PDS 456. The hard X-ray spectrum of PDS 456 shows a deep absorption trough (constituting 50% of the continuum) at energies above 7 keV in the quasar rest frame, which can be attributed to a series of blueshifted K-shell absorption edges due to highly ionized iron. The higher resolution soft X-ray Reflection Gr...
We propose a novel non-contact optical fiber displacement sensor. It uses a radio frequency (RF) interrogation technique which is based on bidirectional modulation of a Mach-Zehnder electro-optical modulator (MZ-EOM). The displacement is measured from the free spectral range (FSR) which is determined by the dip frequencies of the modulated MZ-EOM transfer function. In experiments, the proposed ...
Le sentiment de rejet et mépris, l’absence perspectives, la défiance à l’égard des institutions du pouvoir, paradoxalement combinée avec une demande d’autorité, conduisent aux quatre coins continent manifestations colère sociale. Ces colères s’enclenchent suite décisions politiques ou catastrophes évitables. On citera l’accident ferroviaire en Grèce, les restrictives conservateurs anglais, taxe...
Checkpoint kinase 2 (Chk2), a DNA damage-activated protein kinase, is phosphorylated at Thr-68 by ataxia telangiectasia mutated leading to its activation by phosphorylation at several additional sites. Using mass spectrometry we identified a new Chk2 phosphorylation site at Ser-456. We show that phosphorylation of Ser-456 plays a role in the regulation of Chk2 stability particularly after DNA d...
X-ray and multi-wavelength observations of the most luminous known local (z < 0.3) AGN, the recently discovered radio-quiet quasar PDS 456, are presented. The spectral energy distribution shows that PDS 456 has a bolometric luminosity of 10 erg/s, peaking in the UV. The X-ray spectrum obtained by ASCA and RXTE shows considerable complexity. The most striking feature observed is a deep, highlyio...
Phosphorus is an essential but finite and scarce element, which used extensively in pig farming. For recovering phosphorus from manure, we hypothesize that calcium addition during anaerobic treatment can trigger phosphate granulation enable efficient recovery. In this study, tested the recovery of manure by adding treatment. Size–separated (<200 µm) was treated two identical up-flow sludge blan...
