Compton scattering of X-rays in the bulk flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies. We present Monte Carlo simulations based on a nonlinear algorithm demonstrating the effects of Compton scattering on the H-like, He-like and neutral Fe Kα lines produced in the postshock region of the accretion column. The peak line emissivities...

This is an example of the training data used to learn how predict lowest cloud-base height using a neural network. The Illustration shows 1300 columns that form part array. Each column consists 280 rows, comprising 70 rows each standardised temperature, humidity and pressure indicating location cloud base in binary format. To benefit those wishing begin exploring machine learning atmospheric sc...

Direct and indirect oxidation of guanine in DNA produces guanidinohydantoin (Gh), which is capable of inhibiting replication and inducing mutations during cellular activities. Although some biochemical studies have proposed that Gh may induce exclusively G to C mutations in DNA, other studies have predicted the occurrence of both G to C and G to T mutations. However, the exact reasons for these...

In order to study the possibility of aerodynamic optimization base cavity for slender body, influence with non-cylindrical shape, which is different from traditional column one, investegated by numerical method in paper. The supersonic flow field same body two sorts unconventional cavity, half truncated-cone and column, simulated axisymmetric Navier-Stokes equations. Distribution Mach Number (M...

The post-tensioned frame is one of the recently emerged structural systems for multi-story timber buildings. It characterized by a high level prefabrication and quick erection on construction site. developed at ETH Zurich based beam–column connections with hardwood reinforcement column in connection region base glued-in steel rods. Such system suitable low- mid-rise buildings that are located r...

Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop the seismic design procedures to not only satisfy life safety criteria but also lead to more economical buildings. One of these modern methods of improving seismic performa...

As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...
