This study examines the effectiveness of remediating a well-recognized case of heavy metal pollution at Foundry Cove (FC), Hudson River, New York. This tidal freshwater marsh was polluted with battery-factory wastes (1953-1979) and dredged in 1994-1995. Eight years after remediation, dissolved and particulate metals (Cd, Co, Cu, Pb, Ni, and Ag) were found to be lower than levels in the lower Hu...
Pb cations in PbS quantum rods made from CdS quantum rods by successive complete cationic exchange reactions are partially re-exchanged for Cd cations. Using STEM-HAADF, we show that this leads to the formation of unique multiple dot-in-rod PbS/CdS heteronanostructures, with a photoluminescence quantum yield of 45-55%. We argue that the formation of multiple dot-in-rods is related to the initia...
an artificial neural network (ann) approach was used to model the wheat production. from an extensive data collection involving 40 farms in canterbury, new zealand, the average wheat production was estimated at 9.9 t ha-1. the final ann model developed was capable of predicting wheat production under different conditions and farming systems using direct and indirect technical factors. after exa...
Two bonding models i.e cumullenic and acetylenic models have been proposed to account for thebonding patterns in linear carbon clusters while the bonding patterns in cyclic and 3D geometrieS of theseclusters have remained ambiguous.This work presents the bonding patterns in various C4 and C5 pure clusters at MP2/aug-cc-pVTZ level oftheory. This subject is studied in the light of modern bonding ...
Agricultural development has been a major concern to most developing countries within the last two decades. It represents a cluster of six related but separate concepts; agricultural expansion; increased production per acre of cropped land or per head of livestock; agricultural growth; a situation characterized with agricultural products per agricultural worker, rising income per person employe...
This study compares the impact of Prospective Plantings, Acreage, Crop Production, Production Annual Summary, Grain Stocks, WASDE, Cattle on Feed, and Hogs Pigs reports corn, soybean, wheat, cotton, live cattle, lean hogs markets over 1985–2018. Simultaneous releases several are handled by evaluating report clusters. Our approach allows us to demonstrate relative various information shows when ...
