This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffuse reflectance spectroscopy (DRS) is a rapid proximal-sensing method that is being used more and more in laboratory settings to measure soil properties. Diffuse reflectance spectroscopy research that has been completed in laboratories shows promising results, but very little has been reported on how DRS will work in a field setting on soils scanned in situ. Seventy-two soil cores were obtained from six fields in Erath and Comanche County, Texas. Each soil core was scanned with a visible near-infrared (VNIR) spectrometer with a spectral range of 350-2500 nm in four different combinations of moisture content and pre-treatment: field-moist in situ, air-dried in situ, field-moist smeared in situ, and air-dried ground. Water potential was measured for the field-moist in situ scans. The VNIR spectra were used to predict total and fine clay content, water potential, organic C, and inorganic C of the soil using partial least squares (PLS) regression. The PLS model was validated with data 30% of the original soil cores that were randomly selected and not used in the calibration model. The root mean squared deviation (RMSD) of the air-dry ground samples were within the in situ RMSD and comparable to literature values for each soil property. The validation data set had a total clay content root mean squared deviation (RMSD) of 61 g kg−1 and 41 g kg−1 for the field-moist and air-dried in situ cores, respectively. The organic C validation data set had a RMSD of 5.8 g kg−1 and 4.6 g kg−1 for the field-moist and air-dried in situ cores, respectively. The RMSD values for inorganic C were 10.1 g kg−1 and 8.3 g kg−1 for the field moist and air-dried in situ scans, respectively. Smearing the samples increased the uncertainty of the predictions for clay content, organic C, and inorganic C. Water potential did not improve model predictions, nor did it correlate with the VNIR spectra; r2-values were below 0.31. These results show that DRS is an acceptable technique to measure selected soil properties in-situ at varying water contents and from different parent materials.

Download or read book In Situ Characterization of Soils for Prediction of Stress Strain Relationship of Soft Clay written by K. Arulanandan and published by . This book was released on 1982 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: An electrical method of characterizing fine grained soils is described. A nondestructive method of determining the stress-strain behavior of fine grained soils is developed based on this fundamental characterization of soils. A bounding surface plasticity model is used for the prediction of stress-strain behavior. Correlations are established relating the bounding surface model parameters to the appropriate electrical parameters. In situ prediction of stress-strain behavior of fine grained soils can be made by determining the electrical properties using an in situ measuring technique in a non-destructive manner and obtaining the required bounding surface model parameters from the correlations established. The feasibility of applying this methodology for predicting the stress-strain behavior is demonstrated based on a limited number of laboratory experiments performed on normally consolidated fine grained soils.

This book was released on 2013-06-10 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: HELPS RESEARCHERS DEVELOP NEW CATALYSTS FOR SUSTAINABLE FUEL AND CHEMICAL PRODUCTION Reviewing the latest developments in the field, this book explores the in-situ characterization of heterogeneous catalysts, enabling readers to take full advantage of the sophisticated techniques used to study heterogeneous catalysts and reaction mechanisms. In using these techniques, readers can learn to improve the selectivity and the performance of catalysts and how to prepare catalysts as efficiently as possible, with minimum waste. In-situ Characterization of Heterogeneous Catalysts features contributions from leading experts in the field of catalysis. It begins with an introduction to the fundamentals and then covers: Characterization of electronic and structural properties of catalysts using X-ray absorption fine structure spectroscopy Techniques for structural characterization based on X-ray diffraction, neutron scattering, and pair distribution function analysis Microscopy and morphological studies Techniques for studying the interaction of adsorbates with catalyst surfaces, including infrared spectroscopy, Raman spectroscopy, EPR, and moderate pressure XPS Integration of techniques that provide information on the structural properties of catalysts with techniques that facilitate the study of surface reactions Throughout the book, detailed examples illustrate how techniques for studying catalysts and reaction mechanisms can be applied to solve a broad range of problems in heterogeneous catalysis. Detailed figures help readers better understand how and why the techniques discussed in the book work. At the end of each chapter, an extensive set of references leads to the primary literature in the field. By explaining step by step modern techniques for the in-situ characterization of heterogeneous catalysts, this book enables chemical scientists and engineers to better understand catalyst behavior and design new catalysts for green, sustainable fuel and chemical production.

Available in PDF, EPUB and Kindle. Book excerpt: A non destructive method of characterizing particulate systems using electrical properties is presented. The application of this methodology to the classification of soils is demonstrated. The significance of this approach is that electrical properties of soils such as conductivity, sigma, and dielectric constant, epsilon, as a function of frequency, can be measured in situ. These properties when suitably interpreted can be used to quantify the structure of particulate systems. These structural properties can then be correlated with mechanical properties such as G max, kappa, lambda, and M. This approach provides a non destructive method of characterizing soils for the prediction of mechanical behavior. (Author).

This book was released on 1999 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement and geotechnical design and research engineers, geologists and engineering geologists, and related laboratory personnel. It describes the current practice for measuring in situ mechanical properties of pavement subgrade soils. The tests conducted to measure the mechanical properties of soil strength and stiffness are the primary topics, and these are discussed in the context of design procedures, factors affecting mechanical properties, and the variability of measurements. Information for the synthesis was collected by surveying U.S., Canadian, and selected European transportation agencies and by conducting a literature search. This TRB report provides information on existing and emerging technologies for static and dynamic, and destructive and nondestructive testing for measuring in situ mechanical properties of pavement subgrade soils. Correlations between in situ and laboratory tests are presented. The effects of existing layers on the measurement of subgrade properties, and soil spatial and seasonal variability are discussed. Most importantly, the use of soil properties in pavement design and evaluation are explained. New applications or improvements to existing test methods to support the use of mechanistic/stochastic-based pavement design procedures are also explained.
