In dentistry, acrylates have been used for preparing denture bases for 50 years. Although polymethylmethacrylates (PMMA) are known to be an ideal base material, they possess some undesirable mechanical properties, especially their impact strength and tensile strength, which appear to be unsatisfactory for some applications. Additives and fibers have therefore been used to enhance and improve th...
The value of health impact assessment (HIA) to sectors outside the health domain is increasingly being recognised. A Victorian study explored the application of HIA within a regeneration context. What emerged is a complex analysis of the practical dimensions of applying HIA in this context.
This paper investigates whether advertising has a beneficial or deleterious impact on the demand for magazine subscriptions. If consumers consider advertising a ‘bad,’ publishers must subsidize consumers through lower subscription prices or additional editorial content. If advertising is a ‘good,’ then consumers are willing to pay because it adds value to the magazine bundle. We employ data des...
AIMS Implementation of Health Impact Assessment (HIA) in Danish municipalities has been analyzed using the Roger's Diffusion of Innovation Theory. Municipalities were chosen from among those who presented their health policies on websites according to the status of inclusion of HIA into health policy. METHODS Qualitative interviews were conducted in 6 municipalities (3 with HIA inducted in th...
A calculational procedure is formulated for extracting differential cross sections in the ejected energy from a time-dependent wave-packet method for the electron ionization of hydrogen. The procedure is applied to an s-wave model for electron-hydrogen scattering. In contrast to recent time-independent methods, the differential cross sections are found to be smooth and symmetric. @S1050-2947~97...
OBJECTIVES This paper aimed to employ subject matter experts (SMEs) to assess the extent to which the Korean version of the short-form of the OHIP (OHIP-14 K) is culturally valid and equivalent in Korean. METHODS We approached 17 bilingual Korean SMEs from which 10 independently rated the clarity, relevance, and cultural equivalence of the OHIP-14 K. SME's varied between 10 and 41 years of cl...
The first health impact assessment (HIA) performed on a high level local government policy in New Zealand was undertaken on the Greater Christchurch Urban Development Strategy in 2005. This report describes its development and implementation and the results from the process evaluation including some recommendations made in the assessment. We concluded that HIA is a useful tool for local governm...
In order to determine the quantitative relationship between sheet strength and lignin coverage at the fiber surface, CTMP was blended with softwood bleached kraft pulp (BKP), refined softwood BKP, and hardwood BKP. The morphology of the fibers, fibers properties, fiber surface components and relative bonded area of sheets were investigated. Multi-linear regression equations of tensile strength ...
