The dust disk of HR 4049 Another brick in the Wall
We present the Spectral Energy Distribution of HR 4049 based on literature data and new continuum measurements at 850 μm. The SED shows variable absorption in the UV, and a large IR excess, both caused by circumstellar dust. The shape of the IR excess from 1 μm all the way down to 850 μm can be nearly perfectly fitted with a single blackbody function at T ≈ 1150 K or alternatively with a sum of...
متن کاملProperties of Cement and Mortar Incorporating Marble Dust and Crushed Brick
Blended cements based on the partial replacement of Portland cement clinker (PC) by wastes have been the subject of many investigations in recent years. The use of the replacement materials offer cost reduction, energy savings, arguably superior products, and fewer hazards in the environment. These materials participate in the hydraulic reactions, contributing significantly to the composition a...
متن کاملPhysico-chemical Properties of Brick Kiln Dust Amended Soils and Their Effect on Solanum Tuberosum
The study was conducted to analyze the physico-chemical properties of various levels of brick kiln dust in soil application (0, 5, 10, 15, 20, 25, 30, 40 and 50%), before planting and after harvesting of potato (Solanum tuberosum) crop and to observe their impact on various parameters of potato plant. The pH, EC, CEC, WHC, pore space, sulphate, chloride, phosphorus, magnesium, zinc, manganese a...
متن کاملBrick Generation
A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. The importance of bricks stems from the fact that they are building blocks of the matching decomposition procedure of Kotzig, and Lovász and Plummer. We prove that every brick except for the Petersen graph can be reduced to K4 or the prism by repeatedly applying a ce...
متن کاملStarting from scratch and building brick by brick in comprehension.
During narrative comprehension, readers construct representations of the situation described by a text, called situation models. Theories of situation model construction and event comprehension posit two distinct types of situation model updating: incremental updating of individual situational dimensions, and global updates in which an old model is abandoned and a new one created. No research t...
