We present a comprehensive study of the relation between radio and X-ray emission in neutron star X-ray binaries, use this to infer the general properties of the disc–jet coupling in such systems, and compare the results quantitatively with those already established for black hole systems. There are clear qualitative similarities between the two classes of object: hard states below about 1% of ...

A mechanism for the generation of subsurface cyclones and jets when a warm ring smashes onto a continental slope and shelf is proposed based on the results of a primitive-equation three-dimensional numerical model. The warm ring initially ‘sits’ over a slope with an adjoining shelf in a periodic channel, and its subsequent evolution is examined. The ‘inviscid’ response is cyclonic ‘peeling-off’...

Rivers empty into oceans and lakes as turbulent sediment-laden jets, which can be characterized by a Gaussian horizontal velocity profile that spreads and decays downstream because of shearing and lateral mixing at the jet margins. Recent experiments demonstrate that this velocity field controls river-mouth sedimentation patterns. In nature, diffuse jets are associated with mouth bar deposition...

The European Commission (EC) declared in July 2001 the merger between General Electric (GE) and Honeywell “incompatible with the common market”. The EC argument supposed that dominant position created or strengthened by horizontal overlaps and vertical and conglomerate integration, as a result of which effective competition would be significantly impeded, would end in the monopolization of some...

The main tunnels of Line 16 Lot1 the Grand Paris Express project are underway since 2019 using tunnel boring machines (TBM). They drilled entirely in permeable strata (fine/silty sands, marls, and limestones) at a depth 20÷30 m below groundwater level. Groundwater inflow with high pressure is major issue arrival/departure sections TBMs as well during excavation work connection galleries between...

introduction iran is a frontier of pomegranate fruit production in the world (with almost 40 % of the world`s production). however due to traditional processing operations is not ranked as the largest pomegranate exporter. saveh, neyriz and ferdows are the top pomegranate producing cities in iran. pomegranate is consumed as a fresh fruit as well as processed product as food additive, paste, syr...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

This paper studies the interaction of two droplets splashing on a stationary film. A source term is included in large-density-ratio pseudopotential lattice Boltzmann method to achieve tuneable surface tension. model offers excellent numerical accuracy and stability for droplet impacts liquid films. The influence Reynolds number, Weber film thickness, horizontal/vertical distance between crown g...

Current weather indifferent fields of science and engineering research purposes and different applications are studied. One of the applications of climate studies, the study of the flow over the weir dam and lower exhaust tunnel is aimed at preventing the risk of cavitations. Aeration is known as one of the most economical and practical way to deal with cavitations on rapid spill ways. In the s...
