CLUSTER ANALYSIS OF THE ORGANIC PEAKS IN BULK MASS SPECTRA OBTAINED DURING THE 2002 NEW ENGLAND AIR QUALITY STUDY WITH AN AERODYNE AEROSOL MASS SPECTROMETER

We applied hierarchical cluster analysis to an Aerodyne aerosol mass spectrometer (AMS) bulk mass spectral dataset collected aboard the NOAA research vessel R.H.Brown during the 2002 New England Air Quality Study off the east coast of the United States.Emphasizing the organic peaks, the cluster analysis yielded a series of categories custom congrat

Abstract The objective of this study was to determine the structure, diversity, composition and drivers of AMF communities in succession areas click here of Atlantic Forest.Soil and root samples were collected in three natural ecosystems (mature rainforests, early and late secondary forests) with three areas on each ecosystem.In total, 38 AMF taxa

Swine DNA viruses have developed unique mechanisms for evasion of the host immune system, infection and DNA replication, and finally, construction and release of new viral particles.This article reviews four classes of DNA viruses affecting click here swine: porcine circoviruses, African swine fever virus, porcine parvoviruses, and pseudorabies vir

High dimensionality is a well-known problem that has a huge number of highlights in the data, yet none is helpful for a particular data mining task undertaking, for example, classification and grouping.Therefore, selection of features is used frequently to reduce the data set dimensionality.Feature selection is a multi-target errand, which diminish

In this work, we investigate the effect of biomat for sale hot isostatic pressing on the intermediate temperature tensile property of nickel-base single crystal superalloy.The experimental results indicate that the hot isostatic pressing improves the intermediate temperature plasticity of single crystal superalloy from 6.4% to 9.3%, but the yield s
