municipal water demand study, oklahoma city and tulsa, oklahoma

by using a multiple regression model, this longitudinal study analyzes the methods and results of the factors which influence water consumption in oklahoma city and tulsa, oklahoma during the 20-year period of 1961 through 1980. the explanatory variables utilized in the model include the average price of water per thousand liters (x//1); ..

characteristics of the products of the carbonization of peat in the presence of aluminum chloride

the influence of aluminum chloride on the physicochemical properties of the products of the carbonization of cottongrass peat has been studied. the addition of alcl//3 increases the yield of solid carbonization residue and the amount of oxygen in it, with a decrease in the amount of carbon and in the c/h ratio. 17 refs

behavior of spiral angle $phi$ and the angle of crystallite dispersion $alpha$ of normal cottons with stress

the cotton fiber consists of microfibrils which in turn do have crystalline and amorphous regions. the crystallites are arranged in the form of helices, and with stress the helical configuration changes. this paper examines the configurational changes that occur in the helix and makes it clear that the amorphous regions of the microfibril..

description of the absorption spectrum of iodine recorded by means of fourier transform spectroscopy: the (b-x) system

an in extenso analysis of the (b-x)i//2 iodine absorption spectrum recorded by means of fourier transform spectroscopy is presented. it is shown that the 100 000 recorded transitions covering the 11 000-20 040 cm** $minus$ **1 range and published in several atlases may be recalculated by means of only 46 constants: 45 are dunham coefficie..

leaf injury and elemental concentrations in vegetation near a coal-fired power plant

leaf injury of two native grasses, needleandthread (stipa comata trin. && rupr. ) and prairie sandreed (calamovilfa longifolia $left bracket$ hook. $right bracket$ scribn. ), and plains cottonwood (populus sargentii dode) were slightly greater in a downwind direction from a coal-fired power plant in central wyoming injury usually increase..

identification of krypton krxviii to krxxix specra excited in tfr tokamak plasmas

the emission spectrum of krypton (injected into tfr tokamak plasmas) has been recorded photographically in the 15-300 a spectral range by means of a 2 m grazing incidence spectrograph. preliminary identification work, based on isoelectronic regulairities from known spectra of other ions and ionization equilibrium calculations, has allowed..

analysis of the long range potential of iodine in the b **3 $pi$ //o//u** $plus$ state

a quantum mechanical potential energy curve (ipa potential) of the iodine b **3 $pi$ //o//u** $plus$ state was determined. the analysis of the outer branch of this potential (which encompasses 99 96 of the depth well from v $equals$ 0 to v $equals$ 80) was carried out by means of the multipole expansion of the interaction energies truncat..

electricity conservation for fan drives by variable speed fluid coupling

the efficiency of a variable filling fluid coupling can be considered in two parts. firstly the losses due to slip and secondly the standing loss attributable to the peripheral windage, bearing frictional resistances and the energy required to circulate the oil through the fluid coupling and its cooler. expressed in terms of the maximum r..

cottonseed oil estimation by pulsed nuclear magnetic resonance technique

seed asymmetry and moisture associated with the seeds are known to affect seed oil estimation by pulsed nuclear magnetic resonance (nmr) technique employing free induction decay or single spin echo (se) pulse sequence. using gossypium (cottonseeds) as experimental material, it is shown that transverse relaxation times (t//2) of seed oil, ..
