We examine the excitation of inviscid stationary cross ow instabilities near an isolated surface hump (or indentation) underneath a three-dimensional boundary layer. As the hump height (or indentation depth) is increased from zero, the receptivity process becomes nonlinear even before the stability characteristics of the boundary layer are modi ed to a signi cant extent. This behavior contrasts...

TOPIC: Pulmonary Vascular Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Chest x-rays (CXR) are widely used as the first line investigation for all suspected cardiopulmonary conditions. There certain signs that have classically been described CXR findings suggestive of pulmonary embolism (PE). These include Palla's sign, Westermark and Hampton's Hump. We present a case woman ...

The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...

Most of previous works for discharge measurement structures were carried out in canals with rectangular cross sections. However, in irrigation systems most common irrigation canals, especially lined canals, have trapezoidal cross sections. From practical view point, it is preferable to construct measuring structures without changing the side slopes of the original canals. Usually, a horizontal ...

The X-ray light-curves of the GRB afterglows monitored by Swift display one to four phases of powerlaw decay. In chronological order they are: the burst tail, the ”hump”, the standard decay, and the post jet-break decay. We compare the decay indices and spectral slopes measured during each phase with the expectations for the forward-shock model to identify the processes which may be at work and...

BACKGROUND It is known that in the last decade, spinal disorders are increasing among children, and this generates high concern in areas of healthcare and educational stakeholders to develop preventative strategies to help curb this trend. This paper intends to go a step further in this direction and to explore factors associated with the presence of scoliosis hump, thus contributing to a bette...
