The man, a sculptor and painter, who was covered in white dust later identified as marble, glanced at his feet and said that it was a boat he'd built.
The optimal conditions to achieve the principle objectives of maximizing copper dissolution and minimizing iron dissolution from dust were identified to be a temperature of 30 °C, a leaching time of 3 h, an initial pH of 0.5, a pulp density of 20%, and an ozone flow rate of 1 g/h.
The two of them have been eking out whatever existence they can on this New Earth In Waiting, a dust ball identified as a suitable future home world, albeit after some generous terraforming.
Information on exposure to grain dust was identified by history of grain farming or handling grains.
Such dust particles have been identified as interplanetary dust particles (IPDs), β meteoroids, interstellar dust (ISD), and dust ejected from the Jovian and Saturnian systems through in-situ observations by spacecraft between 0.3 AU and 18 AU heliocentric distances (Grün et al., 2001).
Environmental and personal air monitoring, dust analyses, and biomonitoring have identified that dust and air particulates and fibers, alkaline dust, and polycyclic aromatic hydrocarbons (PAHs) were greatly elevated in the first days after 11 September, with some contaminants remaining above background for 1 3 months (Lioy et al. 2002, in press; McGee et al. 2003; Swartz et al. 2003).
Color-magnitude diagrams achieved from 11 and 15 μm data revealed new information about dust emission, enabled stars with circumstellar dust to be identified, and show that oxygen-rich, and carbon-rich, giants become blue, and turn red again during their evolution.
Besides the exotic dust particles, researchers identified more than 50 other particles of spacecraft debris in the Stardust detectors, according to a report in Science.
The main allergen in house dust has been identified as the excreta of mites that live on skin scales; other mites (those that live in flour, for example) also excrete potent allergens.
Although Hainan Island is located in one of the relative least dusty regions in China, Asian dust has been identified in Hainan soils.
