  • FIFTH EDITION Pantone: CMYK: Back in 2001, when I wrote the first edition of this book (it was called Build Your Own Database Driven Web Site with PHP & MySQL back then), readers were astonished to discover that you could create a site full of web pages without having to write a separate HTML file for each page. PHP stood out from the crowd of programming languages, mainly because it was easy enough for almost anyone to learn and free to download and install.

  •  IUPAC Definition: chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction  Stationary phase (SP): common name for the column packing material in any type of chromatography  Mobile phase (MP): liquid media that continuously flows through the column and carries the analytes  Analyte: the chemical species being investigated (detected and quantitatively measured) by an analytical method...

  • Essential oils (also called volatile oils) generally extracted by distillation from plants are hydrophobic liquids containing volatile aromatic compounds. The essential oils are widely used in perfumes, cosmetics as well as in food and drink as flavor additives. Some essential oils show multiple pharmacological activities and have been considered as the major active fractions of herbal medicines [1–3].

  • QuickSteps books are recipe books for computer users. They answer the question “how do I…?” by providing a quick set of steps to accomplish the most common tasks in a particular operating system or application. The sets of steps are the central focus of the book. QuickSteps sidebars show how to quickly perform many small functions or tasks that support the primary functions. Notes, Tips, and Cautions augment the steps, presented in a separate column so as not to interrupt the fl ow of the steps.

  • High-pressure liquid-solid chromatography (HPLC) is rapidly becoming the method of choice for separations and analysis in many fields. Almost anything that can be dissolved can be separated on some type of HPLC column. However, with this versatility comes the necessity to think about the separation desired and the best way to achieve it. HPLC is not now and probably never will be a turn-key, push-button type of operation.

  • Over 25 years ago, Horvath and Melander, in their fundamental work [1], discussed the reason behind the explosive popularity of reversed-phase liquid chromatography (RPLC) for analytical separations. It was estimated that about 80–90% of all analytical separations were performed in RPLC mode, and the authors noted that “the variation of eluent composition alone extends both retention and selectivity in HPLC [high-performance liquid chromatography] over an extremely broad range.

  • In this eBook I occasionally make comparisons between the D200 and previous Nikon models. In general, whenever this eBook uses the term D1 or D1 series, I’m referring to the entire D1 family (i.e. the D1, D1h, and D1x). The same is true of the D2 family (D2h, D2hs, and D2x). Use of an individual model name in the text indicates a model-specific feature or characteristic. In tables, if there are differences between the cameras, I’ve either added columns for each camera, or separated the information into model-specific tables....
