Mechanical behaviour of fired bricks containing varied amount fine sand (FS) and waste glass powder (GP) was investigated. FS GP were added to at 0, 5, 10, 15, 20, 25, 30, 35 40 wt. %. Firing done 1200 ⁰C samples produced evaluated for compressive flexural strengths while microstructural analyses 25 % GP-clay examined. Results showed that strength highest 30 GP-bricks FS-clay bricks, rose addit...

We study a simple model of spin network evolution motivated by the hypothesis that the emergence of classical space-time from a discrete microscopic dynamics may be a self-organized critical process. Self organized critical systems are statistical systems that naturally evolve without fine tuning to critical states in which correlation functions are scale invariant. We study several rules for e...

the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower.  therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...

Unlike green sand, chemically bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets it`s strength through chemical reaction which is irreversible in nature. Each sand particle is coated with this reacted chemical, which behaves like an inert element after usage once. This inert coating also called “Dead” binder needs to be removed from the us...
