This paper concerns the effect of friction on crack propagation for the centrally cracked Brazilian disk under diametric forces HYSSOP by using a modified finite element method.It shows that the mode II stress intensity factor decreases obviously with the increase of friction after the crack is closed, while friction has no influence on the stress
Abstract Background The sharing of individual participant-level data from COVID-19 trials would allow re-use and secondary analysis that can THINNING HAIR TREAT KIT help accelerate the identification of effective treatments.The sharing of trial data is not the norm, but the unprecedented pandemic caused by SARS-CoV-2 may serve as an impetus for gre
The automotive industry employs a considerable amount of sintered parts, mainly as transmission and engine components.Gears are the parts that mostly benefit, in terms of cost saving, from the near net shape P/M technology.However, the porosity along with the heterogeneous microstructure can detrimentally affect the mechanical behaviour, especially
Plants have evolved a sophisticated immune system that allows them to recognize invading pathogens by specialized receptors.Carbohydrate-binding proteins or lectins are part of this immune system and especially the lectins that reside in the nucleocytoplasmic compartment are known to be implicated in biotic and abiotic stress responses.The class of
Abstract Background Bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) remains a devastating clinical complication seriously affecting the therapeutic outcome of preterm infants.Hence, early prevention and timely diagnosis prior to pathological change is the key to reducing morbidity and improving prognosis.Our primary objective
