Sundry Observations on Urban Security and Terror-Resistant Action Plans in Urban Areas

Nutrition Security in Urban Areas of Latin

The population of Latin America is now largely urban. By 1990, 72 percent of the people of the region were living in cities (Figure 1). By 2020, the urban population could reach 83 percent. With increasing urbanization, the region faces problems of poverty, nutrition, and health that are somewhat different from those when the population was more rural. Thirty-five percent of the people who live...

Global comparison of VOC and CO observations in urban areas

Speciated volatile organic compound (VOC) and carbon monoxide (CO) measurements from the Marylebone Road site in central London from 1998 through 2008 are presented. Long-term trends show statistically significant decreases for all the VOCs considered, ranging from 3% to 26% per year. Carbon monoxide decreased by 12% per year over the measurement period. The VOC trends observed at the kerbside ...

Terrasar X-band Insar Observations in Urban Areas

SAR (Synthetic Aperture Radar) has ability to detect subtle surface movement at the scale of millimeter to centimeter. TerraSAR-X is new radar satellite operated at X-band, multi polarization, and multi beam mode. Compared with C-band or L-band SAR, the X-band system inherently suffers from more temporal decorrelation due to short wavelength (3.1 cm), but is more sensitive to surface deformatio...
