We present CAREY, an alert system notification for regions in state of emergency. CAREY implements the mediator-wrapper architecture on top of the Geospatial Web to visualize risky regions in terms of their weather conditions. We illustrate the formalization of the problem of detecting risky regions as a two-fold problem that relies on annotations of sensor data with the ontology of Observation...

A novel 3-D cuprous iodide polymer [CuI(μ6-L)]n with a Cu/I ratio as high as 3 (1, H2L = 1,3-bis(2H-tetrazol-5-yl)benzene) has been hydrothermally synthesized. The 3-D framework of 1 is constructed by the linkages of rare 1-D cationic aggregates [CuI2+]n and anionic bi-tetrazolate bridges. 1 shows unusually thermochromic luminescent and photocatalytic properties, and its density functional theo...

the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

three hundred twin births from a hospital in tehran, iran have been analyzed for seasonal variation at birth and physical measurements. the results show that the highest twinning rates for mm (5.61), ff (7.73) and mf (5.36) were seen in april, january and september, respectively. the four physical measurements at birth showed non-significant differences among the male and female twins, but mm a...

Counterilluminating animals use ventral photogenic organs (photophores) to mimic the residual downwelling light and cloak their silhouette from upward-looking predators. To cope with variable conditions of pelagic light environments they typically adjust their luminescence intensity. Here, we found evidence that bioluminescent sharks instead emit a constant light output and move up and down in ...

This paper reports the synthesis, characterization, photophysical and structural properties of the homologous series of good emitting pentacoordinated GaQ'2L complexes 1-3, where Q' is 2-methyl-quinolin-8-olate and L is a phenolate substituted in para position with respect to the oxygen donor atom. A combined approach between the experimental structural analysis (i.e. the molecular fragments in...

Transition from the role of passive student to medical practitioner begins with learning the first clinical skill. This transition can be stressful for those experiencing it and to some extent by those coordinating it. Logistically, it requires demonstration of the techniques to the entire class by a single practitioner or to smaller groups of students by multiple practitioners. The former redu...

The ability to synthesize upconversion nanocrystals (UCNCs) with tailored upconversion luminescence and controlled size is of great importance for biophotonic applications. However, until now, limited success has been met to prepare bright, ultrasmall, and monodispersed β-NaYF₄:Yb3+/Er3+ UCNCs. In this work, we report on a synthetic method to produce monodisperse hexagonal NaYF₄:Yb3+/Er3+ nanoc...
