This study is an attempt to investigate the effect of welding rotational and traverse speed on mechanical and microstructural properties of A 430 stainless steel in order to give an effective processing window to achieve an appropriate microstructure and so mechanical properties. There are a wide range industrial uses for ferritic stainless steel. There from they have some problems like grain c...

A beam of polar molecules can be focused and transported through an ac electric quadrupole guide. At a given ac frequency, the transmission of the guide depends on the mass-to-dipole-moment (m/μ) ratio of the molecular quantum state. Here we present a detailed characterization of the m/μ selector, using a pulsed beam of benzonitrile (C(6)H(5)CN) molecules in combination with rotational quantum ...

in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...

The IBr fragment rotational state distributions that result when the NeIBr van der Waals molecule undergoes vibrational predissociation have been measured in a pump-probe laser-induced fluorescence experiment. Independent of initial vibrational state and the number of quanta of vibrational energy lost from the I-Br coordinate, the rotational distributions extend over the full range of energetic...

2014 The odd-odd 158Ho nucleus is studied by means of the reactions 159Tb(03B1, 5n)158Ho and 160Dy(p, 3n)158Ho. The life-time of an isomeric state is measured as T1/2 = (29 ± 3) ns. A rotational band is developed up to spin 16-. LE JOURNAL DE PHYSIQUE LETTRES Classification Physics Abstracts 4.220 4.240 TOME 37, SEPTEMBRE 1976,

The green fluorescent protein (GFP) of the bioluminescent jellyfish Aequorea and its mutants have gained widespread usage as an indicator of structure and function within cells. Proton transfer has been implicated in the complex photophysics of the wild-type molecule, exhibiting a protonated A species excited at 400 nm, and two deprotonated excited-state species I* and B* with red-shifted excit...

Application of thermoplastic materials has increased dramatically in recent decades due to its recyclability, low density, resistance to chemical changes. The friction stir welding process is one of the new methods of solid state welding, which has recently undergone a significant improvement. In this research, using a new tool Made of plain carbon steel st37 in friction stir welding and low co...

The state-to-state vibrational predissociation dynamics of the hydrogen-bonded HCl-H(2)O dimer were studied following excitation of the HCl stretch of the dimer. Velocity-map imaging and resonance-enhanced multiphoton ionization (REMPI) were used to determine pair-correlated product energy distributions. Following vibrational excitation of the HCl stretch of the dimer, HCl fragments were detect...
