Library Juice Concentrate
Library Juice Concentrate is a compilation of the best of Library Juice, an e-zine published by Rory Litwin between 1998 and 2005 that dealt with foundational questions of librarianship during a period of rapid change. Library Juice served as the record for the "library left" during this period, including its veterans and newcomers, while at the same time offering original reflections on traditional questions. The book includes essays and other artifacts that investigate professional neutrality, intellectual freedom, alternative literature, the social effects of technological change, the cultural identity of the librarian, "anarchist librarianship," the Cuba debate, Google's scanning project, subject heading reform, and other issues. The aim of the essays in Library Juice Concentrate is to provoke original thought and to encourage newcomers in the field to participate in professional discourse with confidence and with attention to the intellectual and political struggles of the past..

The World Market for Ores and Concentrates of Molybdenum, Niobium, Tantalum, Titanium, Vanadium and Zirconium: A 2007 Global Trade Perspective
On the demand side, exporters and strategic planners approaching the world market face a number of questions Which countries are supplying ores and concentrates of molybdenum, niobium, tantalum, titanium, vanadium and zirconium? What is the dollar value of these imports? How much do the imports of ores and concentrates of molybdenum, niobium, tantalum, titanium, vanadium and zirconium vary from one country to another? Do exporters serving the world market have similar market shares across the importing countries? Which countries supply the most exports of ores and concentrates of molybdenum, niobium, tantalum, titanium, vanadium and zirconium? Which countries are buying their exports? What is the value of these exports and which countries are the largest buyers? In what follows, Chapter 2 begins by summarizing the regional markets for imported and exported ores and concentrates of molybdenum, niobium, tantalum, titanium, vanadium and zirconium. The total level of imports and exports on a worldwide basis, and those for each region, is based on a model which aggregates across over 150 key country markets and projects these to the current year. From there, each country represents a percent of the world market. This market is served from a number of competitive countries of origin. Based on both demand- and supply-side dynamics, market shares by country of origin are then calculated across each country market destination. These shares lead to a volume of import and export values for each country and are aggregated to regional and world totals. In doing so, we are able to obtain maximum likelihood estimates of both the value of each market and the shares that countries are likely to receive this year. From these figures, rankings are calculated to allow managers to prioritize markets. In this way, all the figures provided in this report are forecasts that can be combined with internal information for strategic planning purposes..

Fresnel lens to concentrate solar energy for the photocatalytic decoloration and mineralization of orange II in aqueous solution [An article from: Chemosphere]
This digital document is a journal article from Chemosphere, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: The decoloration and mineralization of the azo dye orange II under conditions of artificial ultraviolet light and solar energy concentrated by a Fresnel lens in the presence of hydrogen peroxide and TiO"2-P25 was studied. A comparative study to demonstrate the viability of this solar installation was done to establish if the concentration reached in the focus of the Fresnel lens was enough to improve the photocatalytic degradation reaction. The degradation efficiency was higher when the photolysis was carried out under concentrated solar energy irradiation as compared to UV light source in the presence of an electron acceptor such us H"2O"2 and the catalyst TiO"2. The effect of hydrogen peroxide, pH and catalyst concentration was also determined. The increase of H"2O"2 concentration until a critical value (14.7mM) increased both the solar and artificial UV oxidation reaction rate by generating hydroxyl radicals and inhibiting the (e^-/h^+) pair recombination, but the excess of hydrogen peroxide decreases the oxidation rate acting as a radical or hole scavenger and reacting with TiO"2 to form peroxo-compounds, contributing to the inhibition of the reaction. The use of the response surface methodology allowed to fit the optimal values of the parameters pH and catalyst concentration leading to the total solar degradation of orange II. The optimal pH range was 4.5-5.5 close to the zero point charge of TiO"2 depending on surface charge of catalyst and dye ionization state. Dosage of catalyst higher than 1.1gl^-^1 decreases the degradation efficiency due to a decrease of light penetration. .
