This is a good classic report to understand the ductility and drift limits concept in earthquake resistant-design buildings. It contains review on the-state-of-the-practice and the-state-of-the-art in ductility and drift limits concept.

ISO 22762 applies to elastomeric seismic isolators used to provide buildings or bridges with protection from
earthquake damage. The isolators covered consist of alternate rubber layers and reinforcing steel plates.
They are placed between a superstructure and its substructure to provide both flexibility for decoupling
structural systems from ground motion, and damping capability to reduce displacement at the isolation
interface and the transmission of energy from the ground into the structure at the isolation frequency.
This part of ISO 22762 specifies the test methods for determination of the characteristics of elastomeric
seismic isolators and for measurement of the properties of the rubber material used in their manufacture.
The specifications cover testing for all properties required in the elastomeric isolators, such as compression
and shear properties, the durability of the isolators and the physical properties of the materials used in
isolators.
Annex E may be used to review those requirements needing confirmation prior to the test programme.

requirements, design rules, manufacturing tolerances, marking and labelling and test methods for elastomeric
isolators.
Some items of classification and some requirements need to be confirmed before production and these should
be reviewed using the list given in Annex D.

ISO 80000-2 gives general information about mathematical signs and symbols, their meanings, verbal
equivalents and applications.
The recommendations in ISO 80000-2 are intended mainly for use in the natural sciences and technology, but
also apply to other areas where mathematics is used.

Crop production in greenhouses is a growing industry, especially in mild climates, and is very important for the population as a source of income and clean, fresh food. Greenhouses create optimal climate conditions for crop growth and protect crops from outside pests. At the same time greenhouse production increases water use efficiency and makes integrated production and protection (IPP) possible. This book provides technical instructions for practice (what to do and what not to do) and gives answers to the question: How to produce more clean crops and better quality with less water, less land and less pesticide. Suitable greenhouse constructions and their design, adapted to local climates in subtropical, tropical and arid regions and infrastructure conditions are presented. The necessary climate control measures - light transmittance, ventilation, cooling, heating, and CO2 enrichment - and physical measures for pest control, as well as methods for using solar energy to desalinate salty water are described. The results of theoretical research are transferred into methods for practical use, so that readers are equipped to solve their problems in practice as well as to get stimulation for further research and development.
