Webster’s asserts that color is “a phenomenon of light or visual perception that enables one to differentiate otherwise identical objects,” and then goes on to say that the Latin root is celare, “to conceal.” It’s a fine definition, because human perception of color is seamless to the extent that it conceals from us almost every causal detail. This talk will discuss common sources of light, the...

management of environmental education is the most fundamental method of protecting environment which is intended to increase awareness and to make individuals sensitive to the physical, economic, environmental, social and political events and changes. thus, with powerful tools of identifying and describing environmental issues, the individuals can obtain skills for devising methods and solving ...

introduction: inequalities in urban environment are a significant concern. socioeconomic level plays an important role in these inequalities. inequality in environmental hazards is recognized as potential determinants of health disparities. materials & methods: in this study, we used individual and cumulative environmental hazard inequality indices to compare the inequality among 379 neighborho...

Humans have always done nonmonotonic reasoning, but rigorous monotonic reasoning in reaching given conclusions has been deservedly more respected and admired. Euclid contains the first extended monotonically reasoned text available to a large public. I suspect that even Euclid did nonmonotonic reasoning in arguing for the postulates. It is unfortunate that the rigorous monotonic reasoning of Eu...

People who have gout may contend with an increased risk of type 2 diabetes, and women seem more vulnerable than men, according to a large population-based study. The researchers at Harvard Medical School analyzed data from gout patients, and from those without the disease, in the United Kingdom's Health Improvement Network (THIN) database. They found a higher incidence of type 2 diabetes among ...

Current research and improvements in the field of wireless sensor networks are focused on decreasing the power consumption and miniaturization, improved smartness and better wearability of the sensor, and especially with their capability for environmental sensing. Today, the survival of these kinds of networks is a critical issue especially in order to keep environmental information updated. Th...
