Increasingly, women simultaneously balance the roles of mother, parental carer and worker. However, individual role balance strategies among these working 'sandwich' generation women have not been thoroughly explored. Eighteen women combining these three roles were interviewed about their individual role balance strategies. Findings were identified through the framework analysis technique, unde...

We introduce an elegant method that allows the application of diffusing-wave spectroscopy (DWS) to nonergodic, solidlike samples. The method is based on the idea that light transmitted through a sandwich of two turbid cells can be considered ergodic even though only the second cell is ergodic. If absorption and/or leakage of light take place at the interface between the cells, we establish a so...

This paper reports a new method for making high aspect ratio Single Crystalline Silicon (SCS) microstructures om multi layer substrates using Chemical Mechanical Polishing (CMP), Silicon Fusion Bonding (SFB) and Reactive Ion Etching (NE) techniques. First Si-Si02-PolySi-Si02-Si sandwich wafers were fabricated using CMP and SFB. Then microstructures were fabricated on these sandwich wafers using...

Enzyme immunoassaysare very useful for the detectionof low concentrationsof coagulationproteinsand pathological markers in plasma. Analytes in the ng/mL range are measurable with good reproducibility with intraand interassay CVs of less than 5% to 10%. “Sandwich” methods have been developed for von Willebrand factor (plasma concentration about 8 .&.g/mL,Factor IX (5 p.g/mL),proteinC (4 g/mL), a...

Neospora caninum is a parasite responsible for abortion in cows and neuromuscular disease in dogs. Serology is the most widely used technique to evaluate the prevalence of N. caninum in different host populations. A sandwich enzyme-linked immunosorbent assay (ELISA) based on the use of an anti-SRS2 monoclonal antibody was evaluated against the indirect fluorescent antibody test for 100 canine s...

One of the critical goals of adhesive dentistry is to restore the peripheral seal of dentine that is interrupted when enamel is lost as a result of developmental sequelae, trauma, caries or operative intervention such as preparatory excision. For coronal lesions the exposed strata may be bounded by dentine, enamel or both. Manufacturers continue to work vigorously on resin formulations that wil...

A new type of composite structure with a metal foam is reinforced by the metal corrugated core, called metal-foam-filled sandwich panel with a corrugated or V-frame core, is modelled, simulated, and studied in this article. All types of samples with different relative densities of the foam are tested and analyzed under the drop hammer load. The sandwich panel included two aluminium face-sheet, ...

In this paper, static indentation and low velocity impact responses of a fully backed composite sandwich plate subjected to a rigid flat-ended cylindrical indenter/impactor are analytically investigated. The analysis is nonlinear due to nonlinear strain-displacement relation. In contrast to the existed analytical models for the indentation of composite sandwich plates, the stacking sequence of ...

In this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The two outer layers of the sandwich structure are elastic. The viscoelastic materials express the middle layer behavior under electric field and small st...
