Laser based powder bed fusion (L-PBF) is used to manufacture parts layer by layer with the energy of laser beam.The use of L-PBF for building functional parts originates from the design freedom, flexibility, customizability, and energy efficiency of products applied in dynamic application fields such as aerospace and automotive.There are challenges
The Acacia genus is considered one of the most invasive Foot Protection taxa in some habitats, namely coastal dunes, maritime calcareous soils, fresh lands in the valleys, mountainous areas, and the banks of watercourses and roadsides.In Portugal, the severity risk is very high, so this study aimed to evaluate the nutritional and mineral contents o
Switch Blade Opener The crashworthiness of a railway vehicle relates to its passive safety performance.Due to mesh distortion and difficulty in controlling the hourglass energy, conventional finite element methods face great challenges in crashworthiness simulation of large-scale complex railway vehicle models.Meshfree methods such as element-free
Background: The global burden of cardiovascular diseases (CVDs) is mainly driven by modifiable risk factors, with sub-Saharan Africa as the region to bear the brunt of the increasing burden.Emphasis has been on hypertension while side-lining the others to variable extents.Furthermore, the work environment, which plays an important role in the socia
This article reviews the mechanisms of bacterial adhesion to biomaterial surfaces, the factors affecting the adhesion, the techniques used in estimating bacteria-material interactions and the models that have been developed in order to predict adhesion.The process of bacterial adhesion includes an initial physicochemical interaction phase and a lat
