Humans will again set foot on the moon. The moon is covered by a layer of fine dust, which can pose a respiratory hazard. We investigated the pulmonary toxicity of lunar dust in rats exposed to 0, 2.1, 6.8, 20.8 and 60.6mg/m of respirable-size lunar dust for 4weeks (6 h/day, 5 days/ week); the aerosols in the nose-only exposure chambers were generated from a jet-mill ground preparation of a lun...

Note that the variance for ηi is normalized to one since we only observe the sign of Z ′ iγ + ηi. Therefore γ can only be identified up to a scale. A classical example of this two-equation model is the wage regression model, where Yi is the observed wage rate and Di is the labor supply decision, which is decided by the latent calculation that one’s expected wage rate is larger than her reservat...

Proof. First suppose that a ∼H b, so that a = bk for some k ∈ H, and let ah (with h ∈ H) be an artibrary element of aH. Then we have ah = bkh = b(kh) ∈ bH, hence aH ⊆ bH. The proof of bH ⊆ aH is similar. Conversely, suppose that aH = bH. Since a ∈ aH = bH we have a = bk for some k ∈ H. Then a−1b = k−1 ∈ H, hence a ∼H b. (d) Prove that the map g 7→ ag is a bijection from H to aH. Proof. Consider...

Sulfate reduction rates in the surface sediments from 17 stations from an along-slope transect (1,300 m) and from a cross-slope transect (855–4,766 m) were determined in the continental margin sediments of the Benguela Upwelling system. Profiles at all sites in the upwelling area showed increasing sulfate reduction rates from near zero at the surface to a peak at 2–5 cm (up to 29 nmol cm23 d21)...
