متن کاملFlexible Covariance Estimation in Graphical Gaussian Models by Bala Rajaratnam,
In this paper, we propose a class of Bayes estimators for the covariance matrix of graphical Gaussian models Markov with respect to a decomposable graph G. Working with the WPG family defined by Letac and Massam [Ann. Statist. 35 (2007) 1278–1323] we derive closed-form expressions for Bayes estimators under the entropy and squared-error losses. The WPG family includes the classical inverse of t...
متن کاملDisabling pneumoconiosis from limestone dust.
Limestone dust is generally regarded as being relatively harmless. In this paper I wish to record eight cases of pneumoconiosis in limestone workers, in all of which limestone played the sole or principal aetiological part. My attention was first drawn to the condition in November, 1950, when I saw the chest radiograph of a patient whose occupation was limestone crushing. The appearances were m...
متن کاملEffects of Franklin Feed-Grade Limestone vs. Aerion Industries Nutrion Limestone on performance and carcass characteristics of finishing beef steers
Because grains comprise the major portion of diets for finishing beef cattle, and grains contain little calcium, limestone is typically added to finishing diets at levels of .7 to more than 1% of the dry matter. Feedgrade limestone varies in quality and consistency, which could alter performance responses by finishing beef steers. Selection of superior sources of limestone and(or) treatment of ...
متن کاملMathematical Modeling on Open Limestone Channel
Acid mine drainage (AMD) is the outflow of acidic water from metal mines or coal mines. When exposed to air and water, metal sulfides from the deposits of the mines are oxidized and produce acid, metal ions and sulfate, which lower the pH value of the water. An open limestone channel (OLC) is a passive and low cost way to neutralize AMD. The dissolution of calcium into the water increases the p...
