Optimization of a cruciform specimen for fatigue crack growth under in and out-...

Mixed-mode loading conditions are present in different mechanical components. Understanding the influence of in-plane biaxial loading paths parameters allows for fatigue crack growth (FCG) prediction and component fatigue life assessment. Cruciform specimens are used to simulate these conditions, but large specimen dimensions are required in order to keep crack propagation unaffected by specimen geometry. This ...

Alteplase for Massive Pulmonary Embolism after Complicated Pericardiocentesis

Background: The occurrence of a high-risk pulmonary embolism (PE) within 48 hours of a complicated pericardiocentesis to remove a haemorrhagic pericardial effusion, is an uncommon clinical challenge. Case summary: The authors report the case of a 75-year-old woman who presented with signs of imminent cardiac tamponade due to recurring idiopathic pericardial effusion. The patient underwent pericardiocentesis tha...

Effect of Fused Filament Fabrication Processing Parameters on The Mechanical Pr...

This paper studies the influence of Fused Filament Fabrication processing parameters upon mechanical properties and microstructural features of processed PLA parts. The effect of extrusion temperature and raster angle were tested upon two PLA filaments of different trademarks, DoWire and BQ, using a commercial fused deposition extruder. The filling density, layer thickness and velocity were kept constant at 60 ...

Real-world, long-term survival of incident patients with pulmonary arterial hyp...

Background: Pulmonary arterial hypertension (PAH) is a progressive, fatal disease. Long-term outcomes data are scarce in Portugal. We aimed to estimate survival of newly diagnosed PAH at a Portuguese referral center in the modern management era. Methods: Between January 2009 and November 2015 all incident PAH cases were consecutively enrolled in a prospective cohort study. Sixty-five patients were followed up f...

Numerical study of in-plane biaxial fatigue crack growth with different phase s...

Nowadays for real world applications, mechanical components in the automotive, aerospace, aeronautical and other industries are subjected to multiaxial loading conditions. Although the fatigue behavior of materials like steel alloys, aluminum alloys or even magnesium alloys is fairly well established for uniaxial loading, one should not use this knowledge for biaxial loading. Developing new testing machines and...

Numerical study of fatigue crack initiation and propagation on optimally design...

A new generation of smaller and more efficient biaxial fatigue testing machines has arrived on the market. Using electrical motors these machines are not able to achieve the higher loads their hydraulic counterparts can, and therefore the cruciform specimen needs to be optimized Following the authors previous work, several different optimal specimens' configurations were produced, using the base material sheet ...

Entrepreneurship education literature in the 2000s

There seems to be a gap in the literature on entrepreneurship education that prevents it from making stronger contributions towards practice. This study addresses this issue by reviewing the state of the art about entrepreneurship education through the analysis of the contributions made over the 2000s. Theoretical contributions on entrepreneurship education have been increasing and improving in terms of scope a...
