Solar collectors are necessary optical devices for converting solar irradiation into heat. Their characteristics prior to construction. The construction error and the slope of surface mirror facet a parabolic collector have been measured by scanning method. material layer is reinforced fiberglass, which designed made molding method its approximate area 0.8 square meters. In method, structured l...

BACKGROUND The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw. METHODS Casts of uniform thickness were applied...

BACKGROUND High-resolution peripheral quantitative computed tomography (HR-pQCT) is a promising tool to assess the fracture-healing process at the microscale in vivo. Since casts are often used during fracture treatment, they might affect the assessment of bone density, microarchitectural, and biomechanical parameters and the short-term reproducibility of those parameters, e.g., as a result of ...

The work is aimed at experimental research and description of the mechanical behavior degradation fibrous structural composite material strength properties during thermal moisture aging in aggressive (operational) environments different duration temperatures. object study was STEF fiberglass. a laminated fiberglass reinforced plastic obtained by hot pressing glass fabric impregnated with thermo...

Objective: The applications of single-structure fiber-reinforced composite (FRC) in restorative dentistry have not been well reported. This study aimed to clarify the static mechanical properties of anterior crown restorations prepared using two types of single-structure FRC. Materials and methods: An experimental crown restoration was designed for an upper anterior incisor. The restorations we...
