Plant senescence and proteolysis: two processes with one destiny
Diaz-Mendoza,Mercedes; Velasco-Arroyo,Blanca; Santamaria,M. Estrella; González-Melendi,Pablo; Martinez,Manuel; Diaz,IsabelAbstract Senescence-associated proteolysis in plants is a complex and controlled process, essential for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink organs. Protein breakdown in senescing leaves involves many plastidial and nuclear proteases, regulators, different subcellular locations and dynamic protein traffic to ensure the complete transformation of proteins of h...
A New Displacement-based Approach to Calculate Stress Intensity Factors With th...
Gonzalez,Marco; Teixeira,Paulo; Wrobel,Luiz C.; Martinez,ManuelAbstract The analysis of cracked brittle mechanical components considering linear elastic fracture mechanics is usually reduced to the evaluation of stress intensity factors (SIFs). The SIF calculation can be carried out experimentally, theoretically or numerically. Each methodology has its own advantages but the use of numerical methods has become very popular. Several schemes for numerical SIF calculations ha...
