Szechwan is one of the largest, richest and most populous provinces in China, extending from 101?-111? east longitude and 27?-24? north latitude. The population is estimated at 45,000,000. It is essentially an agricultural province; the important crops are rice, sweet potatoes and corn. Though the land is very fertile and productive, the living standard in rural Szechwan is very low. The food o...

In this study, 166 surface sediments and 3 sediment cores from the Bohai Sea (BS), Yellow Sea (YS) and East China Sea (ECS) in China were collected to investigate the spatial and temporal distributions and the transport of PFASs. PFASs concentrations in the surface sediments ranged from below detection limit (<LOD) to 2.78 ng g(-1) with an average value of 0.55 ng g(-1) on a dry weight basis (d...

Bowhead whales (Balaena mysticetus) summering in the eastern Beaufort Sea in 1983 were measured through aerial stereophotogrammetry. Photos were taken from a turbine Aerocommander 690 with wingtip-mounted, calibrated 35-mm cameras. Photos were measured on an analytical plotter with scale data provided by radar altimeter and focal length of the lenses. Coefficient of variation of known-sized tar...

Analyses of Ps and Sp receiver functions from datasets collected by permanent and temporary seismic stations, image a seismic discontinuity, due to a negative velocity contrast across the entire Eastern Alps. The receiver functions show the presence of the discontinuity within the upper mantle with a resolution of tens of kilometers laterally. It is deeper (100-130 km) below the central portion...

A study was carried out to elaborate the medicinal plant diversity at higher altitude of District Shangla, Khyber Pakhtunkhwa, Pakistan. The district is located between 33°-31' to 34°-08' North latitudes and 72°-33' to 73°-01' East longitude. Floristically the area comes under SinoJapanese region. The study revealed that there were 25 medicinal plant species belonging to 21 families. Among thes...

[1] The South Pacific Convergence Zone (SPCZ) is the largest and most persistent spur of the Intertropical Convergence Zone. At the southeastern edge of the SPCZ near 170 W and 15 –20 S a surface ocean salinity frontal zone exists that separates fresher Western Pacific Warm Pool water from saltier and cooler waters in the east. This salinity front is known to shift east and west with the phase ...

China, a country that occupies a vast territory with a diverse climate, varied topography and great variety of flora and fauna, is situated in the southeastern Asia. Its land extends from longitude 73 0 E to 135 0 E, a stretch of over 3,200 miles. From north to south, it spans from latitude 53 0 N to 4 0 N, covering a distance of 3,400 miles. The varied climate crosses frigid, temperate, subtro...

The Udhampur district lies in the northernmost portion of India, approximately at 75” 7’ to 75” 10’ longitude east and 33” 54’ to 33” 57’ latitude north in the State of Jammu and Kashmir. The total area of the district is 2549 km2; it has a hilly topography ranging from 300 m to 2780 m above sea level. The region consists of limestone, quartzites, grit and earthy clay. The soil is sandy except ...

The effects of thermospheric winds and electric fields on the ionospheric FZlayer are controlled by the geometry of the magnetic field, and so vary with latitude and longitude. We adopt a simple model of the daytime F2-layer and study the effects at midlatitudes (25O-65” geographic) of three processes that accompany geomagnetic storms : (i) thermospheric changes due to aurora1 heating; (ii) equ...
