Most Brazilian soils have low natural fertility. The main characteristic is phosphorus (P) deficiency and high P adsorption capacity. This creates the need to add phosphate mineral fertilizers, organic or organomineral. ...

In this work, we prove an existence result for an optimal partition problem of the form min{Fs(A1, …, Am) : Ai ∈ As, Ai ∩ Aj = ∅ for i ≠ j}, where Fs is a cost functional with suitable assumptions of monotonicity and lower ...

Fractional derivative has a memory and non-localization features that make it very useful in modelling epidemics’ transition. The kernel of Caputo-Fabrizio fractional derivative has many features such as non-singularity, ...

In this work, we study the existence of positive solutions for a class of fractional differential equation given by D-t(infinity-infinity)alpha D(t)(alpha)u(t) + u(t) = f(t,u(t)), u is an element of H-alpha (R), ...

In this paper, a nonlinear fractional order epidemic model for HIV transmission is proposed and analyzed by including extra compartment namely exposed class to the basic SIR epidemic model. Also, the infected class of ...

This paper develops a neo-Gramscian conceptual framework in order to examine the ideological constructs and political dynamics that frame the day-to-day workings of the certification-based Fairtrade initiative. To accomplish ...
