Abstract. In this work, we studied the cloud condensation nuclei (CCN) activity and subsaturated droplet growth of phthalic acid (PTA), isophthalic acid, (IPTA) terephthalic (TPTA), significant benzene polycarboxylic acids structural isomers found in atmosphere. Köhler theory (KT) can be effectively applied for hygroscopicity analysis PTA due to its higher aqueous solubility compared IPTA TPTA....

Corn distillers dried grains with solubles (DDGS) has high feed value due to its nutritive contents. The ratio of wet distillers grains (WDG) and condensed distillers solubles (CDS) added during the production ...

A recently proposed theory for diffusion-limited aggregation (DLA), which models this system as a random branched growth process, is reviewed. Like DLA, this process is stochastic, and ensemble averaging is needed in order to define multifractal dimensions. In an earlier work [T.C. Halsey and M. Leibig, Phys. Rev. A 46, 7793 (1992)], annealed average dimensions were computed for this model. In ...

Consider repeated measures data with many zeros. For the case with one grouping factor and one repeated measure, we examine several models, assuming that the nonzero data are roughly lognormal. One of the simplest approaches is to model the zeros as left-censored observations from the lognormal distribution. A random effect is assumed for subjects. The censored model makes a strong assumption a...

Biosorption characteristics of Pb(II) ions from aqueous solution were studied using some residues of solvent-extracted Otostegia persica known as goldar residue biomass. The effects of contact time (0–120 min), the initial pH 3–8, biomass dosage (0.53–2.6 g/L) and the initial lead concentration (5–25 mg/L) on biosorption were investigated. The maximum adsorption capacity of 17.3 mg/g at pH 5.5,...

The Powder FlowWorking Group was charged by IFPRI to produce a review of research challenges on the flow of powders. It includes academics (Robert Behringer, Michel Louge, James McElwaine, Robert Pfeffer, Sankaran Sundaresan, and Jeorg Schwedes), industrial advisors (Karl Jacob, Thomas Halsey, James Michaels, and Paul Mort), and IFPRI officials (Nikolaas de Jaeger, Roger Place). The group held ...

The shortest path problem is one of the most classical problem in combinatorial optimization problem which, given an edge-weighted graph and two vertices, asks to find a path between the two vertices of the minimum length. In this thesis, we consider a generalization of the shortest path problem in which the edge length is time-variable, which we call the time-dependent shortest path problem. T...

The studies of the kinetics and isotherms adsorption of the Reactive Black 5 (RB5) onto bentonite clay were explored in a batch study in a laboratory. The maximum RB5 adsorption conditions of bentonite clay were optimized such as shaking speed (100 rpm), temperature (323 K), pH (10), contact time (40 min), initial dye concentration (170 mg·L−1), and particle size (177 μm). The adsorbent surface...

Equilibrium, kinetics and thermodynamic studies on the removal of Acid Red 14 (AR14) anionic dye by biosorption onto dried waste biomass of Saccharomyces cerevisiae have been investigated. In batch experiments, the parameters studied included the effect of the dye concentration, temperature, contact time, adsorbent dosage, agitation speed, pH, and salt concentration. The pseudo-first-order and ...
