The geographic distributions of mercury-tolerant allozyme genotypes of the enzyme phosphoglucomutase in the shrimp Palaemon elegans and the enzyme phosphoglucose isomerase in the marine gastropod Monodonta turbinata were compared in a mercury-polluted site versus several unpolluted sites on the Israeli coast of the Mediterranean sea. We conclude that in both phosphoglucomutase and phosphoglucos...

The pollution characteristics of Pb, Cd, Zn, Cu and Ni in soil of lead−zinc mining area were studied. The results indicate that the contamination degree followed the sequence of Cd>Pb>Zn>Ni>Cu and concentrations of Pb, Cd and Zn exceeded corresponding limits of the Chinese National Soil Environmental Quality Standard III. The soil was extremely polluted by Cd (Iego=5.26), moderately to heavily ...

P2P mesh-pull live video streaming applications – such as CoolStreaming, PPLive, and PPStream – have become popular in the recent years. In this paper, we examine the stream pollution attack, for which the attacker mixes polluted chunks into the P2P distribution, degrading the quality of the rendered media at the receivers. Polluted chunks received by an unsuspecting peer not only effect that s...

We compare the metallicities of stars with radial velocity planets to the metallicity of a sample of field dwarfs. We confirm recent work indicating that the stars-with-planet sample as a whole is iron rich. However, the lowest mass stars tend to be iron poor, with several having [Fe/H] < −0.2, demonstrating that high metallicity is not required for the formation of short period Jupiter-mass pl...

Abstract The inorganic fraction of fine particles affects numerous physicochemical processes in the atmosphere. However, there is large uncertainty its burden and composition due to limited global measurements. Here, we present observations from eleven different aircraft campaigns around globe investigate how aerosol pH ammonium balance change polluted remote regions, such as over oceans. Both ...

Life forms and their health status are highly dependent on the surrounding environment especially air quality as its constituents basic requirements for life sustenance earth. Booming population dependency machineries such vehicles mass transportation has tortured mother earth with polluted environment. This affected of that we breathe in turn affects our status. Some notable pollutants (PM10, ...

The Bi-directional Reflectance Distribution Function (BRDF) of both clean seawaters and those polluted with oil film was determined using the Monte Carlo radiative transfer technique in which the spectrum of complex refractive index of Romashkino crude oil and the optical properties of case II water for chosen wavelengths was considered. The BRDF values were recorded for 1836 solid angular sect...
