The oil price shocks are an important source that affect on TOT in both oil exporting and importing countries. Hence, this paper compares the effects of real oil price shock on TOT in both oil importing and exporting countries, using Panel Data technique and during 1980-2010. To the best of our knowledge, we applied the nonlinear approach in order to assess the asymmetric impact of the oil pri...

We present an observational and theoretical study of the optical emission from nonradiative shocks in three supernova remnants: the Cygnus Loop, RCW 86 and Tycho. The spectra of these shocks are dominated by collisionally excited hydrogen Balmer lines which have both a broad component caused by proton-neutral charge exchange and a narrow component caused by excitation of cold neutrals entering ...

The Fetal Origins Hypothesis (FOH), put forward in the epidemiological literature and later flourished in the economics literature, suggests that the time in utero is a critical period for human development. However, much attention has been paid to the consequences of fetal exposures to more extreme natural shocks, while less is known about fetal exposures to milder but more commonly experience...

rural households in nigeria are vulnerable to shock because of their limited capacity to make informed decision on secured coping strategies which is further aggravated by some households’ specific socio-economic characteristics. attempts were made to identify shocks being faced by households’ heads and coping strategies. multistage sampling technique was used to select 80 respondents and well ...

We investigate the physical mechanisms of tidal heating and satellite disruption in cold dark matter host haloes using N-body simulations based on cosmological initial conditions. We show the importance of resonant shocks and resonant torques with the host halo to satellite heating. A resonant shock (torque) couples the radial (tangential) motion of a satellite in its orbit to its phase space. ...
