in this research three-dimensional free vibration analysis of functionally graded circular plate with various boundary conditions is achieved. a semi-analytical method, which makes use of the state space method and the one-dimensional differential quadrature method, is used to obtain the vibration frequencies and dynamic responses of circular plates. numerical results are given to demonstrate t...

the development of a conceptual model that best accounts for the different parameters influencing lnapl fate and transport in groundwater is ultimate the key to a successful simulation of lnapl concentration in groundwater. characterization of hydrocarbon sources and identification of areas with heavy lnapl loadings from point and non-point sources is important for land use planners and environ...

This paper relates to the mechanical performance of timber-glass composite beams, which take exceptional advantage of the combination of the materials involved. Beam bending tests were performed with beams made from float glass and heat-strengthened glass. Three different adhesive types were used: silicone, acrylate and epoxy. The test results show that, with a proper design, the timber is able...

BACKGROUND There has been limited decline in undernutrition rates in South Asia compared with the rest of Asia and one reason for this may be low levels of household food security. However, the evidence base on the determinants of household food security is limited. To develop policies intended to improve household food security, improved knowledge of the determinants of household food security...

Laser-induced damage has always been and remains as vexing as it is expensive. Despite a quarter century of work, the problem has not been eliminated or even fully defined-only the technical limits have been increased. Although dielectric thin films have improved over the last 25 years, they remain especially difficult subjects to deal with owing to the multiparameter nature of the nonequilibri...

To improve the effectiveness of a previous regression-based approach for the assessment of the agreement between different analytical methods, two modifications/integrations to the original scheme by means of log10 transformation of data and implementation of inherent combined imprecision are presented in this study.

The application of statistical machine learning techniques to neuroimaging data has allowed researchers to decode the cognitive and disease states of participants. The majority of studies using these techniques have focused on pattern classification to decode the type of object a participant is viewing, the type of cognitive task a participant is completing, or the disease state of a participan...

We introduce a novel mechanism for itinerant ferromagnetism, which is based on a simple two-band model, and, by using numerical and analytical methods, we show that the periodic Anderson model contains this mechanism. We propose that the mechanism, which does not assume an intra-atomic Hund's coupling, is present in both the iron group and some f electron compounds.

OBJECTIVE Construction is a hazardous occupation due to the unique nature of activities involved and the repetitiveness of several field behaviors. The aim of this methodological and theoretical review is to explore the empirical factors influencing unsafe behaviors and accidents on construction sites. METHODS In this work, results and findings from 56 related previous studies were investigat...

The discipline of molecular ecology has undergone enormous changes since the journal bearing its name was launched approximately two decades ago. The field has seen great strides in analytical methods development, made groundbreaking discoveries and experienced a revolution in genotyping technology. Here, we provide brief perspectives on the main subdisciplines of molecular ecology, describe ke...
