We report experimental results for heat-transport measurements, in the form of the Nusselt number Nu, by turbulent Rayleigh–Bénard convection (RBC) in a cylindrical sample of aspect ratio 0 ≡ D/L = 1.00 (D = 1.12m is the diameter and L = 1.12m the height) and compare them with previously reported results for 0 = 0.50. The measurements were made using sulfur hexafluoride at pressures up to 19 ba...

Two conventional onsite sewage treatment and disposal systems (OSTDSs) at Manatee Springs State Park, Florida, USA, were studied to assess their impact on groundwater quality in a shallow karst environment. Sulfur hexafluoride (SF6) and fluorescein were used as tracers to establish connections between the drainfields and monitoring wells. Elevated nutrients were found in all wells where signifi...

Molecular modelling and simulation of the surface tension of fluids with force fields is discussed. 29 real fluids are studied, including nitrogen, oxygen, carbon dioxide, carbon monoxide, fluorine, chlorine, bromine, iodine, ethane, ethylene, acetylene, propyne, propylene, propadiene, carbon disulfide, sulfur hexafluoride, and many refrigerants. The fluids are represented by two-centre Lennard...

Purpose To describe the case of orbital subcutaneous emphysema who was successfully treated with hyperbaric oxygen therapy. Observations Case report. Retrospective analysis of medical records and computer tomography images. A 40 years-old female, with retinal detachment who was seen at the emergency department, two weeks after undergoing a combined procedure of pars plana vitrectomy, scleral ...

Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even...

Sulfur hexafluoride (SF6) is a widely used insulator in the industry, but it also has high global warming potential. Studying electron impact ionization of SF6, particularly measuring energy and angular distributions collision products, can provide valuable information about underlying physics process nature SF6 molecule. In this study, double differential cross sections (DDCSs) for have measur...

Wilcox, P., and Patrick, A. D. (1974). Archives of Disease in Childhood, 49,209. Biochemical diagnosis of cystinosis using cultured ceils. A simple method is described for the biochemical diagnosis of cystinosis using small numbers of cells cultured in medium containing L-35S-cystine. Nonprotein sulphur-labelled compounds were extracted from the cells and separated by thin-layer chromatography....

A new series of Zn(2+), Cu(2+), Ni(2+), and Co(2+) complexes of N(1)-methyl-2-(1H-1,2,3-benzotriazol-1-yl)-3-oxobutanethioamide (MBOBT), HL, has been synthesized and characterized by different spectral and magnetic measurements and elemental analysis. IR spectral data indicates that (MBOBT) exists only in the thione form in the solid state while 13C NMR spectrum indicates its existence in thion...
