Notes on the Prevention of Dust and Gas Explosions in Coal Mines

11 when inert dust or rock dust is placed on all projections and on the floor ( even
if some coal dust be present it will be buried ) the mine will be free from the
possibility of an explosion of coal dust . The bureau ' s work has not gone far

The Sandia Dust Tube

At first glance, it may appear that the expression assumes that dust and air
loading are independent. While this may be true for large particles, for small
particles K is expected to vary in a way that accounts for the effect of dust-air
interactions.

A 5.5-inch-diameter wind tunnel delivering dust-laden air has been designed and constructed. An analysis employing mass and momentum conservation has been developed, to provide a method of specifying the tube output from measurements of input conditions, with little or uncritical use of specialized dust instruments. The tube is capable of producing suspended dust-to-air density ratios up to more than 1, at flow speeds up to 485 feet per second. The tube performance is, however, somewhat erratic. Improvements are planned to stabilize its operation.

Prevention of Dust Explosions in Grain Elevators

Continued recirculation of dust and the constant creation of additional dust

Dust is a novel co-authored by the husband and wife duo of Emanuel and Marcet Haldeman-Julius. Dust is the story of the Wade family, a group of Kansas farmers struggling to get by in the face of harsh conditions and personal tragedy. The story takes place over the course of three generations, but rarely leaves the Kansas farm that we are introduced to in the opening chapter. The authors lived on a farm in Girard, Kansas, which lends an air of authenticity to the writing. Many of the details and characters feel almost autobiographical as a result.

"The redevelopment of the Agar Grove Estate is Camden Council's largest ever regeneration project, involving the phased demolition of eight blocks built as social housing in 1966, and the construction of 500 new homes at social and market rates and shared ownership. The phased "decanting" of residents began in 2012 with the entire project set to span over 15 years of demolition, construction and refurbishment. Living on the 3rd floor of the remaining high rise from the original Modernist development, photographer Alys Morrison has documented the demolition from her living room window with an urgency bordering on obsession. Her observations, using HD video, medium format photography and her iPhone, are regularly transmitted through Instagram, creating a record of and for a community living at the front line of wholesale neighbourhood regeneration, on a long-term building site where whole buildings and ancient trees disappear in a matter of hours. Dust, Dirt from On Site Works comprises a black and white photo essay with selected plates in full colour. An excerpt from Morrison's broad and ongoing body of work, it documents the site's shifting character and its tension with the natural environment, as grass lawns are mowed only to be obliterated by rubble days later. When the estate's towering plane tree unceremoniously disappears, it is as though Morrison has lost a corroborating eyewitness" -- goodpress.co.uk.

IAU Symposium 135 on Interstellar Dust was hosted and co-sponsored by NASA's Ames Research Center from July 26-30, 1988. The symposium was held at the lovely campus of Santa Clara University situated around the historic Santa Clara Mission in California. The meeting was made possible by generous grants from the Astron omy and Relativity Branch of the National Aeronautics and Space Administration and the Galactic Astronomy Program of the National Science Foundation. The International Astronomical Union provided travel grants to a few participants from countries with limited travel funds. We are particularly grateful for the support and services rendered by the dedicated staff at NASA's Ames Research Center and to the" SET! Institute for professionally and expeditiously administering the U.S. grants. This symposium brought together 199 scientists representing 19 different coun tries. The wide range of interest and expertise of the participants - all in some way related to interstellar dust - is reflected in the great variety of topics that were discussed during the symposium ranging from UV, visible and IR observations of interstellar extinction to quantum-statistical calculations of the IR emission from highly vibrationally excited molecules. During the course of the meeting, 41 invited review papers and 140 contributed papers were presented. This book is a collection of the invited review papers. The contributed papers have been published in a companion volume, NASA CP-3036, available from National Technical Information Service, Springfield, Virginia 22161, USA.

Dust is a witty and highly original investigation into the development of modern history writing. This book considers how history writing belongs to the currents of thought shaping the modern world, and suggests that, like dust, the 'matter of history' can never go away or be erased.
