Krotov [9] has considered theoretically another case in which the foam column top is irrigated with the surfactant solution and the foam is in contact with the solution through a filter under which a reduced pressure is created. Here, the constancy of foam expansion ratio and border radii along the height of the foam column is fulfilled only when the volumetric flow rate (qo) corresponds to that derived from Eqs. (5.20) or (5.21). If the value of the volumetric flow rate is higher or lower than q0 (q q0), a distribution of n and r by height is observed. For the cases of q > q0 or q < q0 transcendental equations were derived for the... [Pg.402]

Fig. 5.17 depicts the results about the role of the foaming solution viscosity on the drainage rate of foams with expansion ratio 23.5, produced by blowing gas through solutions of different viscosity for about 4.5 min [52]. After its formation the foam was irrigated with the same solution until a steady-state process was established and the expansion ratio change was measured conductometrically. Constants VLq and wo were calculated from the linearalised Eq. (5.46)... [Pg.431]

There are historic reports of floods in the area (32 J. Rutherford, personal communication) and of an earthquake in 18 B.C. (33). The movement of the expansive Esna shale bed formation that underlies the whole area is also a source of disruption (32). The Esna shale bed formation, which contains montmorillonite clay, swells upon hydration by about 12.5% (32). Therefore, if an adequate amount of water is available, for example from increased irrigation, humidification, or flooding, the movement of this shale formation accelerates. Collectively, these dramatic natural events are the most probable causes of the loss of plaster and painted murals in the lower chamber of the tomb prior to its discovery, and they increasingly (32) threaten tombs in the Thebes area. [Pg.290]

Fluid balance In two patients undergoing transurethral resection, the bladder was irrigated with large volumes of mannitol 5%, which was absorbed and caused pulmonary edema and severe hyponatremia (serum sodium 99 and 97 mmol/1) [63 ]. Hypertonic saline increased the serum sodium concentration and plasma volume expansion corrected hypotension one patient also required positive-pressure ventilation and intravenous noradrenaline. Both recovered completely. [Pg.442]

Roswell Garst had warned Khrushchev that this undertaking could not be done without a concomitant outlay in fertilizer, machinery, irrigation, pesticides, and herbicides. However, Soviet industry capacity, especially the chemical and machinery industries, did not expand at the same rate as the focus was so much on the immediate expansion of land usage. Even so, the engineering feat that was the Virgin Lands Project cannot be considered ultimately as a complete failure. Because of Khrushchev s emphasis on agriculture, more investment was poured into this sector... [Pg.253]

From the formula (7.23) follows, what even in case of a dispersoid uniform distribution in a gas stream on an entry in a spray of an irrigating liquid (c = const), concentration of an impurity in gas on an exit from a drop layer will be a variable on scrubber radius. This fact is caused, on the one hand, by expansion of a flat spray in process of removal from a source and, accordingly, water concentration decrease, and with another—falling of a radial velocity of drops of a liquid at the expense of force of an aerodynamic resistance (Mashayek, 1997 2003 and 2002). [Pg.131]

One thing has always seemed clear. All these innovations are, like the growth of Uruk itself, somehow rooted in the landscape of Mesopotamia and therefore its economy - that is, in the intensive cultivation of cereals through irrigation. This fundamental premise is the traditional inheritance of the field of Near Eastern archaeology, and one that remains largely unchallenged. It underpins explanations of what is actually the best attested - and most distinctive - of the Uruk phenomena the apparent expansion of the people of Uruk into realms far from southern Mesopotamia. [Pg.73]
