Legacy effect of green manure crops fertilized with calcium phosphite on maize production and soil properties

Alexandre Buttler, Mario Fontana, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja

Recycling phosphorus (P) is crucial to meet future P demand for crop production. We investigated the possibility to use calcium phosphite (Ca-Phi) waste, an industrial by-product, as P fertilizer following the oxidation of phosphite (Phi) to phosphate (Pi) ...

Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties

Alexandre Buttler, Mario Fontana, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja

The potential to use calcium phosphite (Ca-Phi) as phosphorus (P) fertilizer may represent an effective recycling of P-containing by-products. A greenhouse experiment was conducted to investigate the effect of Ca-Phi (38 kg P ha(-1)) on soil properties and ...

Fatigue design criteria for strengthening metallic beams with bonded CFRP plates

Alain Nussbaumer, Mario Fontana, Elyas Ghafoori, Masoud Motavalli

Different failure criteria used to prevent fatigue crack initiation in metallic members are described. A series of closed-form analytical solutions were developed to predict the fatigue resistance of metallic beams after strengthening with carbon fiber-rei ...

Finite element modeling for fatigue strengthening of metallic riveted bridges using un-bonded pre-stressed CFRP plates

Andrin Herwig, Alain Nussbaumer, Mario Fontana, Elyas Ghafoori, Gary Scott Prinz

Many old riveted steel bridges remain operational and require retrofit to accommodate ever increasing demands. Complicating retrofit efforts, riveted steel bridges are often considered historical structures and as such structural modifications that affect ...
