We present a high-precision determination of the universal contact parameter in a strongly interacting Fermi gas. In a trapped gas at unitarity, we find the contact to be 3.06±0.08 at a temperature of 0.08 of the Fermi temperature in a harmonic trap. The contact governs the high-momentum (short-range) properties of these systems, and this low-temperature measurement provides a new benchmark for...

Polycarbonate (PC) is an engineering thermoplastic that widely used in electrical and electronic equipment. This plastic often contains tetrabromobisphenol A (TBBA), the most common brominated flame retardant. Thermal degradation of PC-TBBA leads to generation numerous bromo-organic products pyrolytic oil, hindering its appropriate utilization, as well corrosive hydrogen bromide gas. The purpos...

Many new results have poured forth from RHIC ( √ s = 130A GeV). Several appear to be qualitatively different from those at the SPS ( √ s = 17A GeV). “Dynamical” fluctuations in the average transverse momentum, pt, are almost three times larger than at the SPS [1]. Observed HBT radii are small, ∼ 5−7 fm [2], and average transverse boost velocities are large, ∼ .6 c [3]. In particular, that the H...

Current data on crude oil, field/lease condensate, and natural gas liquids produced from NGL plants. Updated a monthly basis.

We present a semiclassical two–fluid model for an interacting Bose gas confined in an anisotropic harmonic trap and solve it in the experimentally relevant region for a spin–polarized gas of 87 Rb atoms, obtaining the temperature dependence of the internal energy and of the condensate fraction. Our results are in agreement with recent experimental observations by Ensher et al. Bose–Einstein con...

Exhaled breath condensate (EBC) pH is considered to reflect the acid-base balance of the airways. Current pH measurements do not take into account the effect of CO2. The aim of the present study was to determine the effect of condensate CO2 partial pressure on pH and to provide a more precise mode of EBC pH determination. Condensate pH and CO2 partial pressure were measured in parallel from 12 ...

In an earlier paper (J. Phys. A: Math. Gen. 26 (1993) 4689) we introduced the notion of cycle percolation in the Bose gas and conjectured that it occurs if and only if there is Bose-Einstein condensation. Here we give a complete proof of this statement for the perfect and the imperfect (mean-field) Bose gas and also show that in the condensate there is an infinite number of macroscopic cycles.

We rely on a variational approach to derive a set of equations governing a trapped self-interacting Bose gas at finite temperature. In this work, we analyze the static situation both at zero and finite temperature in the Thomas-Fermi limit. We derive simple analytic expressions for the condensate properties at finite temperature. The noncondensate and anomalous density profiles are also analyze...

Using the functional integral techniques homogeneous limits of the perturbations of thermal states (describing nonrelativistic Bose Matter at the thermal equilibrium) by bounded cocycles are constructed rigorously. Additionally some elementary properties of these limiting states are discussed and in particular the preservation of the nonpurity in the critical case is proved.

Floating Liquefied Natural Gas (FLNG) units combine gas pre-treatment to tight specifications and natural gas liquefaction that are new to offshore with traditional production systems that are commonly found on oil Floating Production Storage and Offloading (FPSO) vessels. Attention is often focused on the new units, sometimes forgetting that successful operation of the Liquefied Natural Gas (L...
