hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. one of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. the indices which are calculated with the help of radiosonde...

Hemodynamic instability after brain death is an universal clinical problem with effects on potential donor organs. Actual shortage of potential donor hearts continues to raise controversial discussion about adequate donor management with regard to graft quality. From the mid eighties numerous studies investigated the effects of brain death on the cardiocirculatory system and other organs. It co...

The main objective of this study is to evaluate the impact of maritime transportation instability on international trade instability based on wavelet smoothing and spatial panel data econometric method during the period 1990-2012. The results showed that the spatial effects have an impact on international trade instability. So that a sudden 100 percent increase in international trade in the nei...

We present an analysis of modulational instability diffractionless waves in a face-centered-square lattice waveguides featuring non-Kerr nonlinearity, which are composed combination positive and negative refractive indices. The unit cell the consists three different with optical properties. dispersion curve supports flatbands thereby base equations describing model have particular solutions tha...

  This is undoubtedly recognized that economic performance for each country over time is related to a great extent to its political, institutional and legal environment. In fact, these institutions and policies are that determine the governance quality.   In a panel data study, we applied newly developed indices to examine the effects of good governance on FDI for fifteen middle-income countri...

conclusion significant functional performance deficits were observed in the fai group in all tests except single hop test with greater deficits observed in the fai-gw group. hence, these tests can be used to determine the presence of fai. however no deficits were identified for the test involving sagittal plane functional activities suggesting that this test can not be used as a criterion to di...

when a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. in case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints. when the penetrated spudcan is pulled out, much of the soft remolded clay will flow around it and go back into the hole. this event, leaving a deep region of disturbed soil. the disturbe...
