Investigations are presented on the reconstruction of the sound field close to the surface of arbitrarily shaped sound sources. The Nearfield Acoustical Holography (NAH) in spherical coordinates can be used for the reconstruction of sound field parameters. The applicability of the reconstruction method, however, is limited by the validity restrictions of the Rayleigh hypothesis, which are deter...

This article explores the onboarding process for new managers joining food and beverage organisations, role of Organisational Socialisation. Our study identified a heavy reliance on informal training practices, most frequently through on-the-job learning, meaning that newcomers were found to depended their subordinates’ support gain vital institutional information. To mitigate disconnect betwee...

Realizou-se uma investigação nas Baías de Ilha Grande e de Sepetiba sobre a natureza dos hidrocarbonetos não-aromáticos (NAH) em seus sedimentos. A mistura complexa não resolvida (UCM) constituiu de 50 a 90% da concentração dos NAH, que variou entre 2,5 μg g e 193,8 μg g. Na maior parte das amostras a distribuição dos n-alcanos foi unimodal com predomínio de compostos de número ímpar de átomos ...

Lovatt et al. (1979 Plant Physiol 64: 562-569) have previously demonstrated that end-product inhibition functions as a mechanism regulating the activity of the orotic acid pathway in intact cells of roots excised from 2-day-old squash plants (Cucurbita pepo L. cv Early Prolific Straightneck). Uridine (0.5 millimolar final concentration) or one of its metabolites inhibited the incorporation of N...

Enhanced degradation of atrazine has been reported in the literature, indicating the potential for reduced residual weed control with this herbicide. Experiments were conducted to determine the field dissipation of atrazine in three cropping systems: continuous Zea mays L. (CC) receiving atrazine applications each year, Gossypium hirsutum L.-Z. mays rotation (CCR) receiving applications of atra...

Near-field acoustical holography (NAH) is used to reconstruct three-dimensional acoustic fields from a two-dimensional planar measurement. During previous work at BYU, a method has been developed called energy based near-field acoustical holography which reduced the number of needed measurements by 75%. Other recent advances have expanded the theory to interior spaces where multiple sources and...
