OBJECTIVES To document the prevalence of work related ocular (eyeWRI) and nasal (noseWRI) irritation in workers in spinning mills of cotton and synthetic textile fibres and to relate the prevalence of symptoms to atopy, byssinotic symptoms, work history, and measured dust concentrations in the personal breathing zone and work area. METHODS A cross sectional study of 1048 cotton workers and 40...

Pig-house dust originates from feed, bedding, feces, and the animals themselves. If the animals receive drugs such as antibiotics, residues of these substances may occur in manure, in the air, or on surfaces of the respective animal house. In a retrospective study, we investigated dust samples collected during two decades from the same piggery for the occurrence of various antibiotics. In 90% o...

The aim of this study was to determine the relationship between the house-dust mite allergy and prevalence of house-dust mites in dwellings of children who were tested for specific IgE against Dermatophagoides pteronyssinus (D. pteronyssinus) and D. farinae on the suspicion of allergic rhinitis, dermatitis and asthma. All dust specimens collected from children's houses were investigated under a...

We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. The main output of these simulations are the attenuation curves Aλ (i.e. the ratio between the observed, dust extinguished, total intensity to the intrinsic unextinguished one of the galaxy as a function of wavelength). We have explored the dependence of Aλ on a conspicuous set of quantit...

A thermal infrared remote sensing retrieval method developed by Wen and Rose [1994], which retrieves particle sizes, optical depth, and total masses of silicate particles in the volcanic cloud, was applied to an April 07, 2001 sandstorm over northern China, using MODIS. Results indicate that the area of the dust cloud observed was 1.34 million km, the mean particle radius of the dust was 1.44 μ...

This paper proposes a novel dust-storm total path attenuation prediction model. model is formulated as function of specific (dB/km) and the effective distance, which considers non-uniform dust storm intensity variations throughout link. The distance obtained combination link reduction factor. factor developed based on modeled 2-D structure observed characteristics. A measurement campaign atmosp...

Streams of high speed dust particles originate from Jupiter’s innermost Galilean moon Io. After release from Io, the particles collect electric charges in the Io plasma torus, gain energy from the co-rotating electric field of Jupiter’s magnetosphere, and leave the Jovian system into interplanetary space with escape speeds over 200 km s. Galileo, which was the first orbiter spacecraft of Jupite...

We report BV R surface photometry of a lenticular galaxy, NGC 4753 with prominent dust lanes. We have used the multicolor broadband photometry to study dustextinction as a function of wavelength and derived the extinction curve. We find the extinction curve of NGC 4753 to be similar to the Galactic extinction curve in the visible region which implies that the sizes of dust grains responsible fo...

This work investigates the impacts ofmineral dust aerosol on climate using the atmospheric component of the U.K. High-Resolution Global Environmental Model (HiGEM) with an interactive embedded mineral dust scheme. It extends earlier work by Woodage et al. in which direct radiative forcing due to dust was calculated and inwhich it was reported that the global total dust burdenwas increasedwhen t...
