First, you need to understand that the determining factors for any posture are such as: convenience; relative ease of execution; pleasure. Many people do not change their preferences, I use the missionary posture «for all occasions.» It is worth noting that it is one of the most optimal, but the body lovers very quickly get used to it, because of what the amount of pleasure is reduced.

A thoroughly updated new edition of the essential reference on the design, practice, and analysis of clinical trials Clinical Trials Dictionary: Terminology and Usage Recommendations, Second Edition presents clear, precise, meticulously detailed entries on all aspects of modern-day clinical trials. Written and compiled by one of the world’s leading clinical trialists, this comprehensive volume incorporates areas of medicine, statistics, epidemiology, computer science, and bioethics—providing a treasure trove of key terms and ideas. This new edition continues to supply readers with the A–Z terminology needed to design, conduct, and analyze trials, introducing a vocabulary for the characterization and description of related features and activities. More than 300 new entries are now included, reflecting the current usage practices and conventions in the field, along with usage notes with recommendations on when to use the term in question. Detailed biographical notes highlight prominent historical figures and institutions in the field, and an extensive bibliography has been updated to provide readers with additional resources for further study.

Since 1949 the «Committee for Waterfront Structures» has operated on honorary base as a committee of the Society for Harbour Engineering (HTG), Hamburg, and since 1951 also as working group of the German Society for Geotechnics (DGGT), Essen. Its full designation reads «Committee for Simplification an Standardization of Calculation and Construction of Waterfront Structures», which also outlines its goals. Following on from the previous joint publications, this new edition of EAU 2004 contains the safety concept with partial safety factors in accordance with the Eurocodes or the European prestandards as well as with the new edition of the corresponding German standard, partially differing on account of practice experiences. The recommendations continue to satisfy the requirements for international acknowledgement and application with regard to planning, design tendering, the awarding of contracts, building and building supervision. Further, the inspection and accounting procedures for harbour and waterway constructions are given from uniform points of view.

The completely revised and extended Recommendations deal with all questions relevant to the planning and dimensioning of geosynthetics-reinforced earth structures. In addition to the demands on materials and analysis principles, the applications of geosynthetics in a range of foundation systems, ground improvement measures, highways engineering projects, in slopes and retaining structures, and in landfill engineering are discussed. The Recommendations have been supplemented by the following sections: – reinforced earth structures over point or linear bearing elements, – foundation systems using geotextile-encased columns, – bridging subsidence, – dynamic actions of geosynthetic-reinforced systems. The remaining sections have been fundamentally revised and updated in line with current standards and codes of practice.
