This sug- gests that the iridescence color is caused by diffraction, which was demonstrated by an experiment using an argon ion laser illuminat- ing the shell to produce a distinct diffraction image. The strength of the iridescence color can be correlated to both the groove density of the ...
Silicon and aluminium are the second and third most abundant elements of the Earth's crust1. Paradoxically neither element is essential to life and aluminium is inimical to biota. Silicon's non-essentiality is reflected both in its non-existent biochemistry, there are no known Si-C, Si-N, ...

Although the prevalent view is that termite flagellates die because of conditions of starvation and desiccation in the gut during the host molting cycle, the work of L.R. Cleveland in the 1930s through the 1960s provides a strong alternate hypothesis: it was the changed hormonal environment ...

Given the widespread and frequent occurrence of urban flooding, further research into this specific cross-cutting field is mandatory. Keywords: urban water quality; floodwater; human health; water quality monitoring and assessment system 1. Introduction Urban flooding occurs when surface water cannot be...
The sentinel lymph node (SLN) concept (Figure 2), which states that the histologic status of the SLN is predictive of the status of the regional lymph nodes, is based on the orderly spread of tumor from the tumor bed to the regional lymph nodes. Sentinel lymph nodes (SLNs) are defined...
Swimming crab (Portunus trituberculatus), well known for aggression and boldness [4], is a typical species in the study of aquatic animal personality [4,17]. However, the physiolog- ical metabolism affecting boldness is still unclear. In order to answer this question—"What forms, maintains, ...
