in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

joule-thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. in the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic joule-thomson cooling system...

A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...

The influences of droplet size on the growth of self-catalyzed ternary nanowires (NWs) were studied using GaAsP NWs. The size-induced Gibbs-Thomson (GT) effect makes the smaller catalytic droplets have lower effective supersaturations and hence slower nucleation rates than the larger ones. Large variation in droplet size thus led to the growth of NWs with low uniformity, while a good size unifo...

Caledonian United Service Club, Edinburgh, on the evening of Friday, May 28th, Sir Alexander Christison,#ar?.,the senior member of the service, presided, and the following officers were present: Surgeon-Generals G. Bidie, C.l.is.; P. S. Turnbull, K.H.S.; D. Sinclair, c.s.l ; and G. W. R. Hay; Colonels W. P. Warburton, C.S.I.; and A. Stephen ; Brigade-Surgeons G. G. Maclaren, J. Robb and J. Arno...

one whose clinical acumen, painstaking and accurate observations and valuable writings had gained for him a reputation which was world-wide and which added a lustre to British Medicine. John Thomson was born in Edinburgh in 1856, and, after receiving his education at the Academy and University, he studied in London, Berlin and Vienna. His interest was early directed towards diseases of children...

The genus Trypanidius Blanchard, 1846 includes 15 species in the Neotropical Region, nine of which occur in South America. In this contribution, the genus and South American species are redescribed and Trypanidius mimicavus sp. nov. is described from Bolivia. New distributional data are given for T. andicola Blanchard, 1846; T. dimidiatus Thomson, 1860; and T. notatus (Fabricius, 1787). All spe...

Sciacharis s. str. is redefined based on the morphology of its type species, S. fulva Broun, and compared with sympatric genera Chathamaenus Franz (endemic to New Zealand) and Maorinus Franz (known from New Zealand and Australia). As a result, Chathamaenus is placed as a junior synonym of Sciacharis s. str., and Maorinus, originally described as a subgenus of Euconnus Thomson (under a preoccupi...
