Dust to Dust : Evidence for Planet Formation ?
We discuss the properties of several circumstellar debris disk systems imaged with the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer in a survey of young stars with known far-IR excesses. These dusty disks around young (∼ 5–8 Myr) unembedded stars exhibit morphological anisotropies and other characteristics which are suggestive of recent or on-going planet formatio...
متن کاملAssessment of Dust Holding Capacity of Nanofiber Media and Its Ability to Capture Synthetic Dust
Background and Aim: Evaluation of the performance of these products is mainly based on their efficiency in numerical removal of particles in the range of different sizes. While the most important features of filters are the dust holding capacity, and the ability to remove the mass of particles with different densities, fewer studies have addressed this issue. Therefore, the present study evalua...
متن کاملSharp asymptotics for Einstein-λ-dust flows
We consider the Einstein-dust equations with positive cosmological constant λ on manifolds with time slices diffeomorphic to an orientable, compact 3-manifold S. It is shown that the set of standard Cauchy data for the Einstein-λ-dust equations on S contains an open (in terms of suitable Sobolev norms) subset of data that develop into solutions which admit at future time-like infinity a space-l...
متن کاملCardiovascular adverse health effect of occupational exposure to Licorice dust
Introduction: Prolonged use of licorice is known to cause headaches hypertension cardiac arrhythmias edema lethargy shortness of breath sodium retention and loss of potassium in healthy people. However to best of authors' knowledge to date the potential adverse health effects of occupational inhalation exposure to licorice dust have not been examined. This study was therefore under look to ad...
متن کاملPneumoconiosis due to graphite dust.
Lassar Dunner (1945a) recorded the clinical and radiological findings in five men who had been exposed to " pure graphite " dust. They had been exposed for 17, 18, 20, 20, and 34 years respectively, and no other dusts were known to have been implicated. Three of the men had cough, sputum, and dyspnoea; the other two had no complaints. Radiographs showed reticulation with nodulation, and the que...
