Wormhole travel through a Morris-Thorne-Kuhfittig metric is described. Kuhfittig’s description of a traversable wormhole is revisited, and the Morris-Thorne engineering requirements for traversable wormholes are discussed at length, giving useful parameters for physical size, mass, interior geometry, travel times, constraints upon velocity, tidal forces, and stability regimes. Wormhole construc...

respiratory muscles. Thus, the associated perceived effort required to generate a given ventilation during exercise is similarly reduced. The deeper, slower breathing pattern after radiation therapy and delay in the onset of tachypnoea reflect the recruitment of IC both at rest and during exercise as a result of lung volume deflation. Thus, the patient could increase tidal volume and ventilatio...

Global topological defects produce nonzero stress-energy throughout spacetime, and as a result can have observable gravitational influence on surrounding matter. Gravitational effects of global strings are used to place bounds on their cosmic abundance. The minimum separation between global strings is estimated by considering the defects’ contribution to the cosmological energy density. More ri...

Tidal dynamics of shallow estuaries and lagoons is a complex matter that has attracted the attention of a large number of researchers over the last few decades. The main purpose of the present work is to study the intricate tidal dynamics of the Tagus estuary, which states as the largest estuary of the Iberian Peninsula and one of the most important wetlands in Portugal and Europe. Tagus has la...

We present a novel relativistic density-functional approach to modeling quark matter with mechanism mimic confinement. The quasiparticle treatment of quarks provides their suppression due large selfenergy already at the mean-field level. demonstrate that our is equivalent chiral model medium-dependent couplings. dynamical restoration symmetry ensured by construction density functional. Suppleme...

Using data from the Sloan Digital Sky Survey (SDSS) it has recently been shown that the red fraction of satellite galaxies increases with stellar mass. Semi-analytical models, however, predict red satellite fractions that are independent of stellar mass, and much higher than observed. It has been argued that this discrepancy owes to the fact that the models assume that satellite galaxies are in...

Introduction: Much can be learned about tidal dissipation in icy bodies by studying the medium-sized Saturnian satellites. They have densities that range between 960 kg/m3 (Tethys) and ~1460 kg/m3 (Dione) [1]. They accreted very cold (e.g., [2]). Thermal models governed by the decay of long-lived radionuclides yield freezing of the smallest satellites, in a few hundred million years. A Maxwell-...

We consider the problem of allocating berth positions for vessels in tidal bulk port terminals. A berth is defined as a specific location alongside a quay where a ship loader is available for loading or unloading vessels, accommodating only one vessel at a time. In tidal ports, draft conditions depend on high tide conditions, since available depth at low tide is not adequate for the movement of...
