New Refractory Technology Provides Advantages in Monolithic Refractories
There have been a number of different refractory binder systems introduced and utilized over the last 100 years. The most long-standing systems, and the ones employed through today, are based on aluminous cements or phosphates and water that chemically combine to form hydrates, which eventually harden. These traditional systems have limitations that refractory consumers have had to take into co...
متن کاملMakers and Users
I suggest a simple thought experiment. Science fiction books occasionally mention an imaginary device: a replicator. It consists of two boxes; you put an object in a box, close the lid, and instantly get its undistinguishable fully functional copy in the second box. In particular, a replicator can replicate smaller replicators. Now imagine the economy based on replicators. It needs two groups o...
متن کاملبررسی خواص فیزیکی، شیمیایی و مینرالوژیکی خاک بوکسیت معدن بیگلر قزوین برای استفاده در تولید مواد دیرگداز
In this research, the properties and characteristics of Biglar refractories bauxite mines have compared with two types of industrial China's and Iranian (Doplan super) refractory grade bauxite in order to use in refractory industries. At first, physical, chemical and thermal properties, phase and microstructural characteristics have been measured and sintered samples of Biglar Bauxite at differ...
متن کاملA new carrier grade aggregation network model for delivering broadband services to fast moving users
In this article, we present the research challenges that are associated with designing a cost-effective network architecture for delivering broadband services to fast moving users (e.g. in trains). We specifically extended the standard Switched Ethernet technology towards a truly Carrier Grade network solution for fast moving users. Prototype implementations allow us to evaluate dynamic tunnel ...
متن کاملGrowing Eremanthus erythropappus in crushed laterite: A promising alternative to topsoil for bauxite-mine revegetation.
Topsoil is the preferred substrate for areas requiring rehabilitation after bauxite mining. However, topsoil is sometimes lacking and so there is a need to test the suitability of other, locally available substrates. In an abandoned bauxite mine in Southeastern Brazil, small patches of native vegetation spontaneously established in shallow depressions over weathered laterite, suggesting that gr...
