Bullet holes play a major role in the trajectory determination of fired bullets, potentially suggesting where shots were from. Few methods are currently employed to estimate angles incidence bullets using bullet holes. The literature has stressed that knowledge about impact behavior specific bullet–substrate interfaces, including most viable method for estimating angle combination, requires emp...

The detrimental drought effects could be listed as the loss in dry weight and silicon is known to enhance crop tolerance to drought by increasing seedling growth and hydraulic conductivity. To investigate the effects of silicon priming (0, 1 and 2 mM as sodium silicate), on seedling growth and root anatomy of three barley cultivars (Khatam, Rihane, and Nimrooz) a laboratory experiment was condu...

Analytical second derivatives for combined QM/MM calculations have been formulated and implemented in the CHARMM program interfaced with the ab initio quantum mechanical GAMESS and CADPAC programs. This makes possible evaluation of vibrational frequencies and infrared intensities in large systems that cannot be treated effectively by QM or MM alone; examples are polarizable molecules in solutio...

Non-freon gas mixtures (Ar/iso-C4H10) were tested as the chamber gas for 1 and 2 mm gas gap Resistive Plate Chambers (RPCs) with float glass as the resistive electrodes, operated in the streamer mode. With the narrower (1 mm) gas gap, streamer charge is reduced (B1=3), which reduces the dead time (and dead area), associated with each streamer, improving the detection efficiency. The best perfor...

Abstract Increasing data rates in wireless communications are accompanied with the need for new unoccupied and unregulated bandwidth electromagnetic spectrum. Higher carrier frequencies lower THz frequency range might offer solution future indoor communication systems of 100 Gbit/s beyond that cannot be located elsewhere. In this review, we discuss propagation channel measurements an extremely ...

et al. comes next, where the results on temperature structure of chromosphere, chromospheric Figure 1. ALMA images Sun at 1.3 mm (band 6). Left: Full disk image obtained by scanning with a single dish; spatial resolution is 30 . Right: High (1 ) region around sunspot, in interferometric mode mosaicking. Both were December 18, 2015, during commissioning period and processed authors for better vi...
