This paper studies the electrical properties of open-celled aluminium foams manufactured by a novel sintering-dissolution process (SDP) using non-destructive eddy current testing. Experimental measurement results are first presented by means of an impedance analyser under swept frequency testing for the determination of electrical conductivity of Al foams. A double air-cored solenoidal sensor h...

Realizing the full potential of magnetic nanoparticles (MNPs) in nanomedicine requires the optimization of their physical and chemical properties. Elucidation of the effects of these properties on clinical diagnostic or therapeutic properties, however, requires the synthesis or purification of homogenous samples, which has proved to be difficult. While initial simulations indicated that size-se...

MOTIVATION Many biomedical experiments are carried out by pooling individual biological samples. However, pooling samples can potentially hide biological variance and give false confidence concerning the data significance. In the context of microarray experiments for detecting differentially expressed genes, recent publications have addressed the problem of the efficiency of sample pooling, and...

PURPOSE To develop an interactive Web site to help smokeless tobacco (ST) users to reduce or stop their ST use and pilot test it for feasibility, acceptability, and short-term outcomes. METHODS An interactive, multiple-contact Internet ST cessation program was developed, refined based on feedback from 17 ST users, and pilot-tested for feasibility, acceptability, and short-term effects on the ...

Reading and language disorders are common childhood conditions that often co-occur with each other and with other neurodevelopmental impairments. There is strong evidence that disorders, such as dyslexia and Specific Language Impairment (SLI), have a genetic basis, but we expect the contributing genetic factors to be complex in nature. To date, only a few genes have been implicated in these tra...

Interest in uniform multifunctional magnetic particles is driven by potential applications in biomedical and materials science. Here we demonstrate the fabrication of highly tailored nanoscale and microscale magneto-polymer composite particles using a template based approach. Regiospecific surface functionalization of the particles was performed by chemical grafting and evaporative Pt depositio...

Sexual size dimorphism (SSD) is thought to evolve due to sex differences in selection on body size, but it is largely unknown whether intraspecific variation in SSD reflects differences in sex-specific selection among populations. We addressed this question by comparing viability selection between two island populations of the brown anole lizard (Anolis sagrei) that differ in the magnitude of m...
