Air quality models that generate the concentrations of semi-volatile and other condensable organic compounds using an explicit reaction mechanism require estimates of the vapour pressures of the organic compounds that partition between the aerosol and gas phases. The model of Griffin, Kleeman and co-workers (e.g., Griffin et al., 2005) assumes that aerosol particles consist of an aqueous phase,...

The Queensland fruit fly, Bactrocera tryoni (Froggatt) (Q-fly), is a major horticultural pest in Eastern Australia. Effective monitoring, male annihilation technique (MAT) and mass trapping (MT) are all important for control and require strong lures to attract flies to traps or toxicants. Lure strength is thought to be related in part to volatility, but little vapour pressure data are available...

Dengue is a persistent threat to Brazilians. The twentieth FIFA World Cup will take place in Brazil in June and July this year. This paper warning that Dengue fever could be not a significant problem in competition locations. Temperature is a very strong predictor of suitability for Dengue and it seems evident that relative humidity measurements are less satisfactory in biological (ecological, ...

We study the role of surface topology, chemistry, and wall superheat temperature on onset boiling, bubble nucleation growth, possible formation an insulating vapour film by means a novel setup for large-scale MD simulations. To minimise effects system size growth film, we perform simulations in box larger than those previously considered. The effect pressure is isolated imposing constant force ...

A short overview of recent results on the effects of pressure (collisions) regarding the shape of isolated infrared lines of water vapour is presented. The first part of this study considers the basic collisional quantities, which are the pressure-broadening and -shifting coefficients, central parameters of the Lorentzian (and Voigt) profile and thus of any sophisticated line-shape model. Throu...

INTRODUCTION The suggestion has been made that the response of an egg to the action of a spermatozoon or parthenogenetic agent may be similar to that of a nerve to stimulation (Lillie, 1909). If this were so, it might be expected that activation, whether by a parthenogenetic agent or by a spermatozoon, would cause an increase in the permeability of the egg surface; although this increase in per...

Organic aerosol is a highly complex mixture of ~10 4 -10 5 unique compounds all possessing their own set physicochemical properties such as saturation vapour pressure and hygroscopicity. Most these...

The links between chemical properties, including those relating to molecular size, solubility, hydrophobicity and vapour pressure, and rejection of model aromatic micro-pollutants by a tubular, hydrophilic polymer pervaporation membrane designed for irrigation applications were investigated. Open air experiments were conducted at room temperature for individual solutions of fluorene, naphthalen...

The total cross sections for Inelastic collisions between excited sodium and noble gas atoms in their ground states, leading to 2 2 3 P^y2 — — 3 ^3/2 excitation transfer in sodium, have been determined in a series of sensitized fluorescence experiments with pure sodium vapour and its mixtures with noble gases. In the experiments with pure sodium, the sodium vapour pressure was varied over the r...

A heat transfer model of boiling flow in steam heated calandria tubes is presented. The model predictions for vapour formation, heat transfer and pressure difference are compared with experimental data and yield reasonable agreement. Characteristic curves are presented showing predicted evaporation rate, heat transfer and pressure difference for a set of parameters representative of a high grad...
