  • Colloid and surface chemistry occupy a paradoxical position among the topics of physical chemistry. These are areas which have traditionally been considered part of physical chemistry and are currently enjoying more widespread application than ever due to their relevance to environmental and biological problems. At the same time, however, colloid and surface chemistry have virtually disappeared from physical chemistry courses. These topics are largely absent from the contemporary general chemistry course as well.

  • “Just do an Internet search.” “It’s on the Internet.” How often have we said or been told that we could find it on the Internet. This third edition of The Water Encyclopedia: Hydrologic Data and Internet Resources started from a premise that most of the information provided within this publication could be found on the Internet. As our team of contributing authors started reviewing each section within each chapter, it soon became apparent that you cannot always find it on the internet.

  • The genesis of this book began on the sunny shores of southern France in September 1993. For five days in the delightful Mediterranean coastal town of La Londe Les Maures, a gathering occurred of a group of scientists interested in furthering both the understanding and use of thermal infrared (TIR) remote sensing data for analysis of land surface processes.

  • This paper addresses a data-driven surface realisation model based on a large-scale reversible grammar of German. We investigate the relationship between the surface realisation performance and the character of the input to generation, i.e. its degree of underspecification. We extend a syntactic surface realisation system, which can be trained to choose among word order variants, such that the candidate set includes active and passive variants.

  • (BQ) This paper presents an investigation of the effects of machining variables on the surface roughness of wire-EDMed DC53 die steel. In this study, the machining variables investigated were pulse-peak current, pulse-on time, pulse-off time, and wire tension. Analysis of variance (ANOVA) technique was used to find out the variables affecting the surface roughness. Assumptions of ANOVA were discussed and carefully examined using analysis of residuals. Quantitative testing methods on residual analysis were used in place of the typical qualitative testing techniques.

  • The operating parameters considered for the modeling and optimization are specific area of raw materials, moisture content of feedstock, and steam rate. Experimental data show that the oil yield from steam distillation of Vietnam lemongrass is significantly affected by the three mentioned factors. Box-Behnken design (BBD) and analysis of variance (ANOVA) are used to examine the effects of operating parameters on the extraction efficiency.

  • The algorithm for sea surface temperature estimation, proposed by specialists from STI, VAST was described and tested with C-band radiometric data obtained during the Do Son Sea experiment carried out in November 2006. The results for sea surface temperature, obtained from the radiometric data, were compared with the results from contact thermometer measurements and MODIS image processing. Good correspondence was observed.

  • The radiometers, which are used for soil moisture measurement, worked well during the experimental campaign and produced volumetric soil moisture estimates that compared well with the ground-truth measurements. Explanations for the observed discrepancies are presented. The experimental results showed that the model of Choudhury et al. for surface roughness correction provides a better fit to radiometric data over the angular range between 20 ˚ and 50 ˚ for n = 0 (i.e., the cos2θ factor in the exponential in (15) is suppressed).

  • As a result, a model was established which is compatible with the experimental data at the correlation coefficient (R2 ) of 0.99. The optimal conditions were identified as Fe2(SO4)3 concentration of 0.35 M, volume of H2O2 addition at 10 mL and leaching time of 10 h. Under this condition, leaching efficiency of 90.5 percent was achieved.

  • The surface of (1×2) and (1×1) lateral unit cells. The convergence property with respect to the number of Pt layers and the k-point mesh are found. The comparison between different surface types are done. By comparing the calculated results with two different theoretical simulated data, SIESTA and VASP, we found good agreement between them.

  • The pH values will bring effects in flora and fauna nearby, change the taste of water and lead to heavy corrosion in pipe lines. High conductivity naturally indicates the presence of ionic substances dissolved in the river water. However, the result showed that 90% of the study site exceeded the data reported for non-contaminated rivers due to excessive metal ions within the water. At the site nearer to kaolin industry the conductivity is 852 times higher than the non-polluted study site. The industrial discharge also changed the hardness in river water.

  • Written by a premier astronomy expert, this book begins with a discussion of the Sun, from sunspots to solar eclipses. It then features over 100 tables on characteristics of the Moon, and the names, positions, sizes, and other key descriptors of all the planets and their satellites. The book tabulates solar and lunar eclipse, comets, close-approach asteroids, and significant meteor showers dates. Twenty-four maps show the surface features of the planets and their moons. The author then looks to the stars, their distances and movements, and their detailed classification and evolution.

  • Storage devices hold data, even when the computer is turned off. The physical material that actually holds data is called a storage medium. The surface of a floppy disk is a storage medium. The hardware that writes data to or reads data from a storage medium is called a storage device. A floppy disk drive is a storage device. The two primary storage technologies are magnetic and optical.

  • The EU Water Framework Directive (2000/60/EC) is probably the most significant legislative instrument in the water field that was introduced on an international basis for many years. It moves towards integrated environmental management with key objectives to prevent any further deterioration of water bodies, and protect and enhance the status of aquatic ecosystems and associated wetlands. It aims to promote sustainable water consumption and will contribute to mitigating the effects of floods and droughts.
