Since 1962, as an international collaborative project, studies have been in progress of disease among migrants and native populations in Great Britain, Norway, and the United States. The background for the first studies and data on various demographic characteristics, residential history, smoking history, and cardiorespiratory symptoms for migrants and native-born in the United States have been...

GLOSSARY dispersive: Characteristic of waves whose velocity of propagation depends on wave frequency. The shape of a dispersive wave packet changes as it moves along. eigenfunction: Functional shape of the horizontal and vertical components of wave motion versus depth in the ocean for a specific wave frequency. geometrical spreading: Process of amplitude reduction resulting from the progressive...

Periodic progressive waves in shallow to transitional water are described by a Cnoidal Approximation wave theory. The formulation is analytical and largely classical. Periodic waves are assumed, so that the theory does not extend to solitary waves. The solution is completed numerically, as a problem in nonlinear optimisation. The suitability of the theory in shallow to transitional water is dem...

safflower is an oilseed crop with high adaptability to rainfed conditions of iran. it is native crop in iran and due to some morphological characters specially root system it shows good resistance to drought stress. in present investigation to study genetic variation in fall planting of safflower in rainfed condition 100 genotypes were evaluated in a 10×10 simple lattice square design with two ...

Leaky trapped mountain lee waves are investigated by examining the structure of individual linear modes in multilayer atmospheres. When the static stability and cross-mountain wind speed are constant in the topmost unbounded layer, modes that decay exponentially downstream also grow exponentially with height. This growth with height occurs because packets containing relatively large amplitude w...

Aims. To explore the solar coronal heating enigma by an analytical and numerical study of the enhanced phase mixing of harmonic Alfvén waves propagating in gravitationally stratified coronal structures of varying magnetic field divergence. Methods. Corrected analytical solutions are derived to model the dissipation of Alfvén waves propagating in divergent and stratified coronal structures. Thes...

The aim of this work is to identify the physical processes that occur in the network and contribute to its dynamics and heating. We model the network as consisting of individual flux tubes with a non-potential field structure that are located in intergranular lanes. With a typical horizontal size of 200 km at the base of the photosphere, they expand upward and merge with their neighbors at a he...

The effect of magnetic field on torsional waves propagating in non-homogeneous viscoelastic cylindrically aeolotropic material is discussed. The elastic constants and non-homogeneity in viscoelastic medium in terms of density and elastic constant is taken. The frequency equations have been derived in the form of a determinant involving Bessel functions. Dispersion equation in each case has been...
