Partnering Against Corruption Initiative Leads Industry Battle Against Corruption
Publisher: American Society of Civil Engineers
Abstract: The Partnering Against Corruption Initiative (PACI) was organized in 2005 and has gained global recognition as one of the world’s foremost anticorruption forces. The sole focus of PACI is to establish multi-industry ...
Turbulence Spectra and Eddy Diffusivity over Forests
Publisher: American Meteorological Society
Abstract: The main objectives of this observational study are to examine the stability dependence of velocity and air temperature spectra and to employ the spectral quantities to establish relations for eddy diffusivity over forests. ...
Baseline Mass-Transfer Coefficient and Interpretation of Nonsteady State Submerged Bubble-Oxygen Transfer Data
Publisher: ASCE
Abstract: Numerous testing of data reported in the relevant scientific literature widely available to the public has led to the discovery of several physical mathematical models in nature applicable to the subject of oxygenation in ...
Bonding Time and Prestress Loss in Precast Pretensioned Concrete during Steam Curing
Publisher: ASCE
Abstract: During steam curing of concrete, the axial restraint of pretensioned strands causes thermal prestress loss of the strands accumulated until sufficient bonding occurs. A theoretical model is presented in this paper to predict ...
Dissipative Energization of Baroclinic Waves by Surface Ekman Pumping
Publisher: American Meteorological Society
Abstract: A two-layer quasigeostrophic model is used to study the effect of lower boundary Ekman pumping on the energetics of baroclinic waves. Although the direct impact of the Ekman pumping is to damp the total eddy energy, either ...
Why Are the Climatological Zonal Winds Easterly in the EquatorialUpper Troposphere?
Publisher: American Meteorological Society
Abstract: Using 16 years of NCEP?NCAR reanalysis data on the 200-mb surface, it is shown that in the deep Tropics, the horizontal transient eddy momentum flux accelerates the zonal mean zonal wind. This acceleration is mainly due ...
The Segregation of Aerosols by Cloud-Nucleating Activity. Part II: Observation of an Urban Aerosol
Publisher: American Meteorological Society
Abstract: The submicron aerosol of metropolitan Seattle was segregated into CCN and non-CCN fractions by a high-flux thermal diffusion cloud chamber in series with a dichotomous separator. Each segregated fraction of the five-hour ...
Baroclinic Multiple Zonal Jets on the Sphere
Publisher: American Meteorological Society
Abstract: Multiple zonal jets are investigated with a two-level primitive equation model on the sphere in which both baroclinicity and planetary radius are varied. As in the case for a two-layer quasigeostrophic model on a ?-plane ...
Improving Policy for Stormwater Management: Implications for Climate Change Adaptation
Publisher: American Meteorological Society
Abstract: Lack of local information on climate change impacts is increasingly recognized as an important barrier to progress in adaptation. However, simply providing decision makers with higher-resolution climate information will ...
