The paper presents a one-stage method of development results to obtaining effective structural and thermal insulation products based on cellular concrete with variatropic structure the study their properties. In addition, study's determining influence initial components quantitative ratio foam-aerated mixture technological regimes. For this purpose, model system [Ca(OH)2;Al;H2O;NaF] has been cr...

The Intra-guild predation model is an interaction between three species where two of them compete and prey on each other for the same resource. This study considers stage structure combines Beddington-DeAngelis Holling type I as functional responses in model. Furthermore, equilibrium point stability will be analyzed. numerical result at shows that solution converging toward so population stable...
