Laser directed energy deposition (LDED) can be deployed for depositing high-performance materials various engineering applications. Alumina-forming steel is a material that possesses excellent corrosion and oxidation resistance, finding application in the power generation sector. In present work, LDED using powder feeding (LDED-PF) was used to deposit Fe20Cr5.5AlY alloy single-track, multi-trac...

This article presents a novel methodology conducted under controlled laboratory conditions to assess the dynamic behavior of components railway tracks by applying an unbalanced mass excitation force. The for obtaining accurate measurements, which uses different parameters, is based on device, and from these data, transmissibility mass-elastomer system estimated. For assessment behavior, sine sw...

indoor radon and thoron have been measured in the houses ofmoradabad district, uttar pradesh india, by means of solid state nuclear trackdetectors. radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. radon exists in soil gas building materials and indooratmosphere to name but a f...

Although the circuit mediating contextual fear conditioning has been extensively described, the precise contribution that specific anatomical nodes make to behavior has not been fully elucidated. To clarify the roles of the dorsal hippocampus (DH), basolateral amygdala (BLA), and medial prefrontal cortex (mPFC) in contextual fear conditioning, activity within these regions was mapped using cell...

Abstract. To enable the separation of pre- and postdepositional components length distribution (partially annealed) horizontal confined fission tracks, is corrected by deconvolution. Probabilistic least-squares inversion corrects natural track histograms for observational biases, considering variance in data, modelization, prior information. The histogram validated its variance–covariance matri...

Zonal-mean storm-track shifts in response to perturbations in climate occur even in idealized simulations of dry atmospheres with axisymmetric forcing. Nonetheless, a generally accepted theory of the mechanisms controlling the storm-track shifts is still lacking. Here, mean available potential energy (MAPE), a general measure of baroclinicity that is proportional to the square of the Eady growt...

As high-speed trains operate in more and more countries and their maximum speed increases, the vibration induced by the train has become an important issue. The dynamic coupling between the vehicle, track and ground has to be assessed for its effects on safety, stability and maintenance costs. A particular issue, especially for soft soils, is the critical speed at which the train reaches the wa...

The average angular distributions of neutron emissions have been measured in the Fuego Nuevo II (FN-II) dense plasma focus device (5kJ) by means of CR-39 plastic nuclear track detectors. When pure deuterium is used as the filling gas, the data can be adjusted to a Gaussian function, related to anisotropic emission, superposed on a constant pedestal, related to isotropic emission. When deuterium...
