The effect of bar sealing parameters on the heat seal strength of oriented polypropylene (OPP)/metallic cast polypropylene (MCPP) laminate film was investigated. Based on the results obtained from the parametric study, a bar sealing process window was developed. All points drop within the process window are combinations of platen temperature and dwell time that produce acceptable heat seal. Opt...

Porcelain laminate veneers have been a common treatment strategy in dental clinics. It is a conservative method for treatment of esthetic and functional problems in anterior region of oral cavity. Wide range of dental ceramics is now available on market for fabrication of laminate veneers. Clinician should have enough knowledge regarding the composition and properties of these materials in orde...

School children often encounter traumatic injuries like a crown fracture. They create serious functional, esthetic and psychological problems. Achievement of promising restoration that preserves its aesthetics and strength is the greatest desire for both children and their parents and is a challenging task for the dentist. The restorative options in these cases usually include composite resin a...

In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu(2+) ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N-O groups of two N-nitroso-N-pentyl-hydroxy-laminate ligands [Cu-O = 1.9042 (17) and 1.9095 (16) Å]. The hy-droxy-laminate monoanions are bidentate chelating ligands. The Cu(2+) cations form stacks alo...

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...

The literature has described the clinical aspects of the laminate veneer restoration; however, the laboratory preparation of these veneers has not been detailed This paper outlines a step-by-step laboratory technique for the construction of a commercially available laminate veneer, Mastique.® J_Jaminate veneers have been successfully used on patients with hypoplasia, tetracycline staining, fluo...
