numerical study of an observed orographic mesoscale convective system. i. simulated genesis and comparison with observations

the interaction of topographically induced thermally and mechanically driven diurnal flow regimes in the lee of the rockies is shown to lead to the growth of a mesoscale convective system (mcs). an orographic mcs observed during the 1977 combined south park area cumulus experiment and high plains experiment is numerically simulated with a..

r-matrix calculation of photoionisation from rydberg states in strontium

this paper presents the first detailed theoretical calculation of numerous observables investigated in sr using stepwise laser excitation techniques. measurements concern the 5p/sub 1/2/ns and 5p/sub 3/2/ns j=1 autoionising levels excited through the 5sns /sup 1/s/sub 0/ rydberg states: isolated resonances as well as interacting autoionis..

application of cellulosic and noncellulosic materials in power transformers

kraft cellulose insulating materials and other products such as cotton cellulose and noncellulosic aramid fibre pressboard are tested and evaluated under conditions encountered in power transformers. new insulating boards made of cellulosic and noncellulosic fibre base are presented. their performance is studied. the report deals with the..

eigenchannel r-matrix calculation of the j=1 odd-parity spectrum of barium

the j=1 odd-parity spectrum of barium is studied through a combination of the eigenchannel r-matrix and multichannel quantum defect (mqdt) methods. short-range parameters used by mqdt to describe electronic channel interactions are determined by performing r-matrix calculations in ls coupling and the (ls/jj) frame transformation is used t..

quantum-interference effects in some fields

the authors derive quantum-interference effects for (a) nonspinning particles in einstein and yang-mills fields and (b) spinning particles in einstein and einstein-cartan fields

liquid crystal polymers' conformation of deuterated parts by sans

summary form only given, as follows. comb like like crystal polymers are polymers on which each monomer is grafted a hanging liquid crystal molecule. the bulk state has the classical liquid crystal phases (nematic, smectic). the conformation of a chain in these phases is solved with the help of a small angle neutron scattering. the values..

acoustic cotton-mouton effect in antiferromagnets

a rotationally invariant theory of a magnetic acoustic birefringence is developed for tetragonal antiferromagnets with the rutile structure (fluorides) in a situation with k//l//b//4//z, where k, l, and b are, respectively, the wave vector of sound, and the antiferromagnetic and magnetic field vectors, and 4 is the tetragonal symmetry axi..

mapping surface energy balance components by combining landsat thematic mapper and ground-based meteorological data

surface energy balance components were evaluated by combining satellite-based spectral data with on-site measurements of solar irradiance, air temperature, wind speed, and vapor pressure. maps of latent heat flux density ( lambda e) and net radiant flux density (r/sub n/) were produced using landsat thematic mapper (tm) data for three dat..

use of a tocodynamometer to investigate bladder instability

the tocodynamometer is used by obstetricians to detect uterine contractions during labour. it has also been used to measure bladder pressure quantitatively in a selected group of patients, namely those with enlarged bladders. the authors' aim was to investigate whether the tocodynamometer could be used to measure pressure in other groups ..

vertical tube air flows in the turbulent mixed convection regime calculated using a low-reynolds-number k approximately epsilon model

heat transfer to fluids flowing in vertical tubes under conditions of combined forced and free ('mixed') turbulent convection can exhibit marked departures from the case of purely forced convection. significant impairment or enhancement of heat transfer can occur, depending upon flow orientation and the influence of the degree of buoyancy..
