In this study, the functional morphology of the mandibular glands of pharaoh ant queens is investigated through histological and behavioural observations. The mandibular glands of queens of different age stages and mating status were examined at the light microscopical as well as the ultrastructural level. The results clearly show a high activity of the gland at the time of hatching, followed b...

AlSi10Mg inclined struts with angle of 45° were fabricated by selective laser melting (SLM) using different scanning speed and hatch spacing to gain insight into the evolution of the molten pool morphology, surface roughness, and dimensional accuracy. The results show that the average width and depth of the molten pool, the lower surface roughness and dimensional deviation decrease with the inc...

introduction: the purpose of this case report is to analyze the results of vestibuleplasty around an over-denture based on dental implants to determine the evidence on the effectiveness of laser-assisted surgery and soft tissue management in implant dentistry. case report: the patient in this case report was a 57 year- old male who was completely edentulous, with a mandibular over denture based...

This paper discusses the use of high power lasers in the manufacture of microelectromechanical systems (MEMS). The ability to process a wide range of materials, and to produce truly three-dimensional structures with tolerances at the micron or sub-micron level, give laser micromachining some key advantages over other more established micromachining techniques. Previous work in this area is revi...
