Physical activity and efficiency of mental work.

Abstract: To investigate the influence of physical activity on the efficiency of mental work 50 Ss between 19 and 21 yr. of age did step-ups (for physical activity) and added, subtracted, multiplied, and divided simple sums of one digit (for mental work). Analysis disclosed a significant (p < .01) increase in mental work when the physical activity was of 2 and 5 min. duration and significant (p < .01) decrease when the physical activity was of 10 and 15 min. duration.

Effects of body waves and soil amplification on seismic earth pressures

Abstract: To design a retaining wall, conventional Mononobe–Okabe method, which is based on the pseudo-static approach and gives the linear distribution of seismic earth pressures in an approximate way, is used to compute the seismic earth pressures. In this paper, pseudo-dynamic approach is used to compute the seismic earth pressures on a rigid retaining wall by considering the effects of time, phase difference in shear and primary waves and soil amplification along with the horizontal and vertical seismic accelerations and other soil properties. Design value of the seismic active earth pressure coefficient is found to increase with increase in the seismic accelerations, phase difference in body waves and soil amplification, whereas the reverse trend is observed for the passive case. Influence of various soil parameters on seismic passive earth pressure is more significant than that for the active case under harmonic seismic loading. Results are provided in the combined tabular and graphical non-dimensional form for both the seismic active and passive earth pressures. Present results are compared with the available results in literature to validate the proposed non-linearity of seismic earth pressure distribution.

Trilinearization and localized coherent structures and periodic solutions for the (2 + 1) dimensional K-dV and NNV equations

Abstract: In this paper, using a novel approach involving the truncated Laurent expansion in the Painleve analysis of the (2 + 1) dimensional K-dV equation, we have trilinearized the evolution equation and obtained rather general classes of solutions in terms of arbitrary functions. The highlight of this method is that it allows us to construct generalized periodic structures corresponding to different manifolds in terms of Jacobian elliptic functions, and the exponentially decaying dromions turn out to be special cases of these solutions. We have also constructed multi-elliptic function solutions and multi-dromions and analysed their interactions. The analysis is also extended to the case of generalized Nizhnik–Novikov–Veselov (NNV) equation, which is also trilinearized and general class of solutions obtained.

Recent Advances in Urea- and Thiourea-Based Metal Complexes: Biological, Sensor, Optical, and Corroson Inhibition Studies

Abstract: Ureas and thioureas, otherwise known as carbamides and thiocarbamides, respectively, are rich sources of nitrogen. Urea has a wide range of applications in agriculture, the chemical industry, and a...
