The phase diagram of the spin-3/2 Blume-Capel model in two dimensions is explored by conventional finite-size scaling, conformal invariance and Monte Carlo simulations. The model in its τ -continuum Hamiltonian version is also considered and compared with others spin3/2 quantum chains. Our results indicate that differently from the standard spin-1 Blume-Capel model there is no multicritical poi...

Critical end points and tricritical are multicritical that separate lines of continuous transitions from first order in the phase diagram many systems. In models like spin-1 disordered Blume–Capel model repulsive Blume–Emery–Griffiths model, point splits into a critical bicritical with an increase disorder coupling strength respectively. to make distinction between these two points, we investig...

Growing microalgae on vegetable waste (rotten potatoes) media is not only a plausible technique to replace expensive commercial but also way of reducing feed costs for rearing zooplankton and fish larvae in aquaculture. As starting an inevitable step up, Monoraphidium littorale was grown 25% (T1), 50% (T2), 75% (T3) digested rotten potato supernatant (DRPS) at the same time Bold Basal Medium (B...

Surface waters to be used as resource for drinking water, waste water and sludge produced in treatment processes are very complex media containing soluble, colloidal and particulate matter. Apart from inert or dead matter the colloidal and particulate phase is mainly composed by organic bio-particles (viruses, bacteria, protozoa). Treatment processes like disinfection of potable water, hygienis...
