We characterize the near-infrared (NIR) dust attenuation for a sample of ∼5500 local (z . 0.1) star-forming galaxies and obtain an estimate of their average total-to-selective attenuation k(λ). We utilize data from the United Kingdom Infrared Telescope (UKIRT) and the Two Micron All-Sky Survey (2MASS), which is combined with previously measured UV-optical data for these galaxies. The average at...

Interim Reports on work of the International Institute for Applied Systems Analysis receive only limited review. Views or opinions expressed herein do not necessarily represent those of the Institute, its National Member Organizations, or other organizations supporting the work. Abstract This paper is a first step in trying to develop a concept incorporating population growth and population agi...

To investigate the effects of gender on static and dynamic postural stability in community dwelling healthy older adults. Thirty men and 30 women older than 65 years participated in the study. They completed 4 balance tests, including one-legged stance test (OLST) with eyes open (EO), OLST with eyes closed (EC), Sharpened Romberg (SR) and Dynamic postural stability (Turn 180). Means of static a...

Studying the energetics of marine top predators such as seabirds is essential to understand processes underlying adult winter survival and its impact on population dynamics. Winter survival is believed to be the single most important life-history trait in long-lived species but its determinants are largely unknown. Seabirds are inaccessible during this season, so conventional metabolic studies ...

In many subsistence communities worldwide, labor-saving technologies such as mechanized water pumps and grain mills are introduced during the first stages of economic acculturation. These technological changes affect the efficiency with which resources are acquired and processed. If women can produce the same amount of a good in less time and if the time savings is reallocated to less energetic...

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...

Like any other precipitation process, in supercritical water hydrothermal synthesis (SWHS), the need to improve product quality and minimize production cost requires understanding and optimization of Particle Size Distribution (PSD). In this work, using Population Balance Equation (PBE) containing nucleation and growth terms, the reactive precipitation of zirconia nanoparticles prepared by ...

Operational variables of a mineral processing circuit are subjected to different variations. Steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. In thispaper, a dynamic simulator containing some of the major equipment of mineral processing...
