Whether you are studying to take the LEED® Accredited Professional (AP) Exam or you are a student in a construction related program, this book is for you! Thorough and complete coverage explains the “how” and the “why” of sustainable construction so you can be better prepared for the LEED® AP Exam and life in the field.
Sustainable Construction and Design provides a solid foundation in the underlying conceptual framework of sustainable construction. Part One focuses on the foundations of sustainability, including the origins of sustainable design, the ecological structure of matter and the physical laws that govern it.
Part Two provides a sustainable construction roadmap and how the concepts can be applied in the real world. It Addresses the LEED® prerequisites and credits and follows a commercial construction project through the certification process.
Sustainable Construction and Design also expands sustainable concepts beyond the LEED® Credit Template and ideas into the residential arena as it reviews the process of a collaborative project that students created with Habitat for Humanity. It explains in depth about the qualities and conditions needed to create a successful design charrette, as it is the critical vehicle that brings both collaboration and whole-systems thinking into the process. The DVD that is included with the textbook assists in creating the loose structure of a design charrette.

B30.2 applies to the construction, installation, operation, inspection, and maintenance of hand-operated and power-driven overhead and gantry cranes that have a top-running single-girder or multiple-girder bridge, with one or more top-running trolley hoists used for vertical lifting and lowering of freely suspended, unguided loads consisting of equipment and materials. The requirements included in this Volume also apply to cranes having the same fundamental characteristics such as cantilever gantry cranes, semi-gantry cranes, and wall cranes. Requirements for a crane used for a special purpose such as, but not limited to, non-vertical lifting service, lifting a guided load, or lifting personnel are not included in this Volume.
B30.2 is to be used in conjunction with equipment described in other volumes of the ASME B30 series of safety standards.
Careful application of these B30 standards will help users to comply with pertinent regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed in these volumes.
Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of overhead and gantry cranes with B30 equipment, plus all potential governing entities.

Nearly all solids are compised of grains. However most studies treat materials as a continious solid. The book applies analysis used on loose granular materials to dense grainular materials. This title’s main focus is devoted to static or dynamic loadings applied to dense materials, although rapid flows and widely dispersed media are also mentioned briefly. Three essential areas are covered: Local variable analysis: Contact forces, displacements and rotations, orientation of contacting particles and fabric tensors are all examples of local variables. Their statistical distributions, such as spatial distribution and possible localization, are analyzed, taking into account experimental results or numerical simulations. Change of scales procedures: Also known as “homogenization techniques”, these procedures make it possible to construct continuum laws to be used in a continuum mechanics approach or performing smaller scale analyses. Numerical modeling: Several methods designed to calculate approximate solutions of dynamical equations together with unilateral contact and frictional laws are presented, including molecular dynamics, the distinct element method and non-smooth contact dynamics. Numerical examples are given and the quality of numerical approximations is discussed.

Micromechanics provides a link between the structure and the properties at different scales of observation. This book deals with micromechanical analysis of interfaces and interface layers and presents several modelling tools. These range from the rigorous method of asymptotic expansions to practical finite element simulations, suitable for this class of problems. The corresponding two parts of the book are self-contained, so they can be read separately.

Application of Surface-Wave Methods for Seismic Site Characterization
Author: Sebastiano Foti, Stefano Parolai, Dario Albarello and Matteo Picozzi | Size: 2.85 MB | Format:PDF | Quality:Original preprint | Publisher: Surveys in Geophysics, Volume 32, Number 6 | Year: Published online: 3 June 2011 | pages: 49 (777-825)
Abstract
Surface-wave dispersion analysis is widely used in geophysics to infer a shear wave velocity model of the subsoil for a wide variety of applications. A shear-wave velocity model is obtained from the solution of an inverse problem based on the surface wave dispersive propagation in vertically heterogeneous media. The analysis can be based either on active source measurements or on seismic noise recordings. This paper discusses the most typical choices for collection and interpretation of experimental data, providing a state of the art on the different steps involved in surface wave surveys. In particular, the different strategies for processing experimental data and to solve the inverse problem are presented, along with their advantages and disadvantages. Also, some issues related to the characteristics of passive surface wave data and their use in H/V spectral ratio technique are discussed as additional information to be used independently or in conjunction with dispersion analysis. Finally, some recommendations for the use of surface wave methods are presented, while also outlining future trends in the research of this topic.

tomorrow (20-March-2012 = 01-Farvardin-1391) on time 08:44:27 (+3:30 GMT) new Persian year will be stared, and many Persian people around the words (about 300,000,000) celebrates these days and coming spring.
Nowrūz (Persian: نوروز, IPA: [nouˈɾuːz], meaning "[The] New Day") is the name of the Iranian New Year in Iranian calendars and the corresponding traditional celebrations. Nowruz is also widely referred to as the "Persian New Year".
Nowruz is celebrated and observed by Iranian peoples and the related cultural continent and has spread in many other parts of the world, including parts of Central Asia, Caucasus, South Asia, Northwestern China, the Crimea and some groups in the Balkans.
Nowruz marks the first day of spring and the beginning of the year in Iranian calendar. It is celebrated on the day of the astronomical vernal equinox, which usually occurs on March 21 or the previous/following day depending on where it is observed. As well as being a Zoroastrian holiday and having significance amongst the Zoroastrian ancestors of modern Iranians, the same time is celebrated in parts of the South Asian sub-continent as the new year. The moment the Sun crosses the celestial equator and equalizes night and day is calculated exactly every year and Iranian families gather together to observe the rituals.
Originally being a Zoroastrian festival, and the holiest of them all, Nowruz is believed to have been invented by Zoroaster himself, although there is no clear date of origin. Since the Achaemenid era the official year has begun with the New Day when the Sun leaves the zodiac of Pisces and enters the zodiacal sign of Aries, signifying the Spring Equinox.
The Jewish festival of Purim is probably adopted from the Persian New Year. It is also a holy day for Sufis, Ismailis, Alawites, Alevis, and adherents of the Bahá'í Faith.
The term Nowruz in writing, first appeared in Persian records in the 2nd century AD, but it was also an important day during the time of the Achaemenids c. 548–330 BC), where kings from different nations under the Persian empire used to bring gifts to the Emperor, also called King of Kings (Shahanshah), of Persia on Nowruz. The significance of Nowruz in the Achaemenid empire was such that the great Persian king Cambyses II's appointment as the king of Babylon was legitimized only after his participation in the New Year festival (Nowruz).
The UN's General Assembly in 2010 recognized the International Day of Nowruz, describing it a spring festival of Persian origin which has been celebrated for over 3,000 years. During the meeting of The Inter-governmental Committee for the Safeguarding of the Intangible Heritage of the United Nations, held between 28 September – 2 October 2009 in Abu Dhabi, Nowrūz was officially registered on the UNESCO List of the Intangible Cultural Heritage of Humanity.
