Book Description
Upwelling areas are among the most fertile regions of the ocean. In principle, upwelling is caused by the divergence of the flow in the surface layer of the ocean which arises as a consequence of a particular wind field, the presence of a coastline, or other special conditions. Since deeper oceanic layers are usually enriched wi th nutrients, it is the permanent supply of nutrients which forms the basis for the high producti vi ty of upwelling reg ions. The study of upwelling and its consequences were, for a long time, the task of individual scientists from all disciplines of marine science. Today, it is perhaps the branch of oceanography where interdisciplinary coopera tion has developed best. Becoming aware of the large potential yield of upwelling regions, governments in creased the funds for upwelling research. With research activities developed on a larger scale, interdisciplin ary cooperation became a necessity. On the international level, several symposia documented the rapid development. Three volumes reflect the results of these scientific meetings (Rapp. Proc.-Verb. 159, 1970; Inv. Pesq. 35, 1, 1971; Tethys §.' 1-2, 1974). The present book contains selected papers from the Third Symposium on Upwelling Ecosystems, which was held in Kiel in September 1975. Although the third of a series of meetings, it was the first where the word "ecosystem" stood in the title for a scientific program.

Book Description
New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.

Book Description
Get ready to see Rails as you've never seen it before. Learn how to extend the framework, change its behavior, and replace whole components to bend it to your will. Eight different test-driven tutorials will help you understand Rails' inner workings and prepare you to tackle complicated projects with solutions that are well-tested, modular, and easy to maintain. This second edition of the bestselling Crafting Rails Applications has been updated to Rails 4 and discusses new topics such as streaming, mountable engines, and thread safety. Rails is one of the most extensible frameworks out there. This pioneering book deep-dives into the Rails plugin APIs and shows you, the intermediate Rails developer, how to use them to write better web applications and make your day-to-day work with Rails more productive. Rails Core developer Jose Valim guides you through eight different tutorials, each using test-driven development to build a new Rails plugin or application that solves common problems with these APIs. You'll learn how the Rails rendering stack works and customize it to read templates from the database while you discover how to mimic Active Record behavior, such as validations, in any other object. You'll find out how Rails integrates with Rack, the different ways to stream data from your web application, and how to mix Rails engines and Sinatra applications into your Rails apps, so you can choose the most appropriate tool for the job. In addition, you'll improve your productivity by customizing generators and responders. This book will help you understand Rails' inner workings, including generators, template handlers, internationalization, routing, and responders. With the knowledge you'll gain, you'll create well-tested, modular, and robust solutions for your next project.

Book Description
Captured in a Scottish border raid and held for ransom by her ancestral enemies, bewitching Storm Eldon trusted Tavis Maclagan's vow not to harm her, but he would stop at nothing to get her into his bed. Undeterred by her fiery temper, he silenced her sharp tongue with honeyed kisses, until the hatred in her heart turned into burning love.

Book Description
Does your Rails code suffer from bloat, brittleness, or inaccuracy? Cure these problems with a regular dose of test-driven development. Rails 4 Test Prescriptions is a comprehensive guide to how tests can help you design and write better Rails applications. In this completely revised edition, you'll learn why testing works and how to test effectively using Rails 4, Minitest 5, and RSpec 3, as well as popular testing libraries such as factory_girl and Cucumber. Do what the doctor ordered to make your applications feel all better. Side effects may include better code, fewer bugs, and happier developers. Your Ruby on Rails application is sick. Deadlines are looming, but every time you make the slightest change to the code, something else breaks. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Plus, it has bugs. You need test-driven development, a process for improving the design, maintainability, and long-term viability of software. Containing both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you've integrated those features into your coding practice, you'll learn how to use popular third-party testing tools such as RSpec, Mocha, Cucumber, and factory_girl. You'll test the component parts of a Rails application, including the back-end model logic and the front-end display logic. Using Rails examples, you'll learn how to use testing to enable your code to respond better to future change. Plus, you'll see how to handle real-world testing situations. This completely revised edition contains a new tutorial, as well as new examples throughout the book. Many chapters, including the JavaScript chapter, have undergone major changes to reflect new tools and new practices. And there are brand new chapters on testing for security, and testing external services. What You Need:Ruby 2.1, Rails 4

Book Description
Excerpt from Spicilegium Floræ Maroccanæ The earliest notice that I have found of botanical research into the Marocco Flora is in the Istoria Botanica' of Zanoni (cura tor Of the Botanic Garden at Bologna), published in 1675. He had received plants and seeds from Tangier from a Mr. Alexander Balaam, who appears to have been a merchant trading with Tangier during some part of the time when that town was held by the Portuguese and the English. The next contribution, and amore considerable one, is contained in a list published (1696) in the 19th vol. Of the Philosophical Transactions (p. 239 et seq), but drawn up in 1673 by Mr. Spotswood, a surgeon who lived there during the English occupation, and gathered plants which he gave to the same Mr. Balaam and to Dr. Morison at Oxford There is some difficulty in identifying many of the species named; and I have not thought it worth while to cite the plants contained in Mr. Spotswood's list.
