Over half the population of the world eats a diet in which rice predominates and such a diet usually has a low mineral content. This is certainly true for the diets consumed by most of the people of Ceylon (Nicholls, 1936; Nicholls & Nimalasuriya, 1939; Bibile, Cullumbine, Watson & Wickramanayake, 1949; Cullumbine, ~gqga), and it is difficult to understand how these people can grow and maintain...

Abstract Silver nanoparticle is useful metallic due to plasmonic property. One of the most important application silver enhancing Raman spectrum using so-called surface-enhanced spectroscopy (SERS). Mostly, researchers synthesize colloidal nanoparticles and deposite on substrate form SERS substrates. In this work, we simplified synthesis by use microwave. We have successfully grown unpolished s...

Policies are used to control the behavior of large-scale systems. After policies are designed and before policies are implemented, it should be possible to analyze the policies and verify that they behave as expected. Graph transformations provide a good method to carry out the analysis and verification because of the intuitive representation of policies and the mature theory. Here, we show how...

A phase-field approach for quantitative simulations of grain growth in anisotropic systems is introduced, together with a new methodology to derive appropriate model parameters that reproduce given misorientation and inclination dependent grain boundary energy and mobility in the simulations. The proposed model formulation and parameter choice guarantee a constant diffuse interface width and co...

Note that if ∑ agg ∈ I, then ∑ ag = 0 so that ∑ agg = ∑ agg− ∑ ag1 = ∑ ag(g−1), so that every element in I is a Z-linear combination of the elements g− 1 (g ∈ G, g 6= 1). Also, if ∑ ag(g− 1) = 0, it follows that ag = 0 for all g so that the elements g − 1 (g ∈ G, g 6= 1) are linearly independent. (b) Notice that the ideal generated by the elements s− 1 (s ∈ S) is the same as the ideal generated...

truction combined with measures such as the improvement of dwelling houses and the better storage of grain to lessen the rat population? Admittedly the I M. S is merely advisory in such matters, but for what it is worth I venture to express the following opinions, viz. (i) That in years to come it will be recognised that the one and only method of dealing successfully with Bubonic Plague is rig...

Fibrous dysplasia is a benign fibrous-osseous lesion in which normal bone is replaced by fibrous connective tissue and immature bone, affecting only one (monostotic) or several bones (polyostotic) and mainly occurring in children and young adults. When present in facial bones, the maxilla is more frequently involved than the mandible, which can cause facial asymmetry in addition to dental compl...

Twenty-six patients, 5-13 years of age, demonstrated 67 pairs of contralateral occlusal fissure and buccal, or lingual pit carious lesions which were restored with a spherical high-copper amalgam. One restoration of each pah" was allowed to remain as carved, while the other was finished and polished 24 hours after insertion. Each restoration was evaluated clinically by three independent examine...

We study numerically and analytically the coarsening of stripe phases in two spatial dimensions, and show that transient configurations do not achieve long ranged orientational order but rather evolve into glassy configurations with very slow dynamics. In the absence of thermal fluctuations, defects such as grain boundaries become pinned in an effective periodic potential that is induced by the...
