Soil texture has been commonly associated with the population density of Heterodera glycines (soybean cyst nematode: SCN), but such an association has been mainly described in terms of textural classes. In this study, multivariate analysis and a generalized linear modeling approach were used to elucidate the quantitative relationship of soil texture with the observed SCN population density redu...

An initial application of CPT results is to evaluate soil type and soil stratigraphy. One of the more common CPT-based methods to estimate soil type is the chart suggested by Robertson et al (1986) based on cone resistance, qc and friction ratio, Rf. Although newer charts have been developed based on normalized parameters, the simple chart based on qc and Rf is still popular because it is easy ...

Genetic fingerprinting demonstrated in previous studies that differently sized soil particle fractions (PSFs; clay, silt, and sand with particulate organic matter (POM)) harbor microbial communities that differ in structure, functional potentials and sensitivity to environmental conditions. To elucidate whether specific bacterial or archaeal taxa exhibit preference for specific PSFs, we examine...

Ocean Drilling Program (ODP) Leg 156 examined hydrological, geochemical, structural, and sedimentological processes at the toe of the northern Barbados accretionary prism (Shipley, Ogawa, Blum, et al., 1995). As part of this program, more than 400 samples were collected from Sites 948 and 949 for grain-size analysis. The primary objective of these analyses was to accurately determine weight per...

of the Thesis Evaluation of Ar-Ar ages of Individual Mica Grains for Provenance Studies of Loess, Long Island, NY by Jian Zhong Master of Science in Geosciences State University of New York at Stony Brook 2001 Loess in a one-meter thick section on the SUNY Stony Brook Campus has been studied for grain size distribution and provenance. The loess provenance has been evaluated using single crystal...

BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

Heat flow controls the design and operation of a wide range engineered geosystems. This study uses transient thermal probe measurements to determine evolution conductivity air-dry water-saturated sand–silt mixtures as function effective stress. Results confirm that soils varies with state stress, dry mass density, mineralogy, pore fluid properties highlight effect contact resistance on granular...
