Refractory Properties of Termite Hills Under
The investigation centered on how additives such as graphite, asbestos varied at different percentages can affect the refractory properties of pure termite hills. Experimental analysis was carried out on such properties as refractoriness, porosity, permeability, thermal shock resistance, linear shrinkage, bulk density and specific gravity. Through pure termite hill has low refractoriness (1400C...

متن کاملGeochemistry of Termite Hills as a Tool for Geochemical Exploration of Glass Sand in the Iraqi Western Desert
Sand glass deposits was located in the mid of the Western Desert of Iraq. It is situated within Rutba Formation (Ceno-manian). Ancient traditional mining method is still used in exploitation the unconsolidated white glass sand from glass sand quarry. The overburden thickness ranges from 2 to 4 m in average. Termite hills were observed around the glass sand quarry extending far from the quarry a...
متن کاملThe Total Luminous Efficiency of Luminous Bacteria
Methods are described for measuring the light emitted by an emulsion of luminous bacteria of given thickness, and calculating the light emitted by a single bacterium, measuring 1.1 x 2.2 micra, provided there is no absorption of light in the emulsion. At the same time, the oxygen consumed by a single bacterium was measured by recording the time for the bacteria to use up .9 of the oxygen dissol...
متن کاملTop‐down network analysis characterizes hidden termite–termite interactions
The analysis of ecological networks is generally bottom-up, where networks are established by observing interactions between individuals. Emergent network properties have been indicated to reflect the dominant mode of interactions in communities that might be mutualistic (e.g., pollination) or antagonistic (e.g., host-parasitoid communities). Many ecological communities, however, comprise speci...
