Incorporating waste stone powders into the production of reactive powder concretes (RPCs) can be eco-friendly. Since high cementitious material content is used in producing RPCs, CO2, as a harmful greenhouse gas, was for carbonation curing this study. For purpose, limestone substituted by 0%, 18%, 36% and 54% silica sand specimens were cured water up to 90 days CO2 chamber 48 hours. The physica...

aerosol formation due to ions in the atmosphere is not well understood, although it seems to play an important role in cloud formation. the ions in the atmosphere can enhance cloud formation and can increase nucleation as well as impeding the evaporation from the surfaces of the droplets. recently there has been some experimental work to find the relation between ions concentrations and cloud i...

Numerical simulations of tropical-cyclone-like vortices are performed to analyze the effects of unidirectional vertical wind shear and translational flow upon the organization of convection within a hurricane’s core region and upon the intensity of the storm. A series of dry and moist simulations is performed using the Pennsylvania State University–National Center for Atmospheric Research Mesos...

The non-modal transient properties of the Eady baroclinic model with a simple heating parameterization are examined. The time-dependent non-modal behavior of the moist baroclinic model is investigated by calculating the energy amplification of optimal perturbations for relevant time-scales and by calculating the energy evolution of random initial conditions. Enhanced non-modal growth on time-sc...

One hundred seventy pigs averaging 21 +/- 1 d of age (initially 5.4 and 5.8 kg, respectively) were used in each of two experiments to determine the effect that further heat processing by moist extrusion has on the nutritional value of soybean products fed to the early-weaned pig (d 0 to 14 postweaning). The experiments were designed as randomized complete blocks with treatments arranged as a 2 ...

PURPOSE Postmastectomy irradiation provides an excellent model for irradiated skin care practices because of the relatively uniform surface and radiation compared with other situations in which radiation-induced moist desquamation is common. We designed a study to test the effect of prophylactic 3M Cavilon No-Sting Barrier Film (No-Sting) on the rates of moist desquamation compared with sorbole...

[1] In this paper, changes in isentropic circulations associated with global warming in the A1B model outputs for the 20th and 21st centuries are analyzed. The changes in the circulations on dry and moist isentropes are quantified through the use of three bulk measures of the circulations: mass transport, entropy transport and effective stratification. The circulation on dry isentropes is expec...

[1] Atmospheric mixing ratios of CO2 are strongly seasonal in the Arctic due to mid‐latitude transport. Here we analyze the seasonal influence of moist synoptic storms by diagnosing CO2 transport from a global model on moist isentropes (to represent parcel trajectories through stormtracks) and parsing transport into eddy and mean components. During winter when northern plants respire, warm mois...

We tested the generalist annual plant Polygonum persicaria (Polygonaceae) for adaptive differentiation in drought responses. Populations from one consistently moist and two variably dry sites were grown in moist and drought conditions in a greenhouse. Physiological, morphological, and reproductive data were collected. All three populations maintained similar levels of fitness in both drought an...

The photolytic degradations of imidacloprid, carbofuran, diazinon, chlorpyrifos, pyridaben, propoxur, and esfenvalerate were independently compared in both moist (75% field moisture capacity at 0.33 bar) and air-dry microbially viable soils at 5 microg/g. All compounds were applied to sandy soil except for propoxur, which was applied to sandy loam soil. Diazinon was applied to both sandy soil a...
