An Introduction to Probabilistic Seismic Hazard Analysis
This document explains the calculations involved in Probabilistic Seismic Hazard Analysis (PSHA), and the motivation for using this approach in combining many models and data sources to create a quantification of the possibility of intense ground shaking at a site. This document is made by Prof. J.W. Baker from Stanford Univ.. It could act perfectly as a good intro before digesting the following PSHA's books:
- McGuire, R. K. (2004). Seismic Hazard and Risk Analysis, Earthquake Engineering Research Institute, Berkeley.
- Kramer, S. L. (1996). Geotechnical earthquake engineering, Chapter 4, Prentice Hall, Upper Saddle River, N.J.
- Reiter, L. (1990). Earthquake hazard analysis: issues and insights, Columbia University Press, New York.
----- These all reveal the black-box of the PSHA program (e.g. EZ-FRISK).

I would like to introduce the necessity of mentioning the access date of the links, we are providing with our threads in the forum. Since I have joined in this great forum, I am observing that many of our members are mentioning, these links are dead, those are not working etc. etc. But the truth is those links were working at the time it was published in this forum. It is proved because some of our members got help from those links and hit the THANKS already.
As time passes, it may not working due to sevaral reasons such as removal of files by uploader, or complaint received by the uploading agency etc. etc. So, if anybody tells those links are not working for the former post, it does bother ther person who is the first uploader of that file.
Thus, I wanna suggest to mention the access date of links during when we are uploading the files in the forum threads. I would like to request our moderators and members to think of this issue. I hope it will work, if we include in our forum rules during publishing of threads.
Complementary Approaches for Using Ecotoxicity Data in Soil Pollution Evaluation
M. D. Fernandez, J. V. Tarazona - Complementary Approaches for Using Ecotoxicity Data in Soil Pollution Evaluation
Publisher: Nova Science Publishers | 2008-11 | ISBN: 1606921053 | PDF | 81 pages | 5.32 MB
The assessment of soil quality has usually focused on human health protection as the main objective. Recently, criteria for the protection of ecosystems have been incorporated and ecotoxicological analyses are recommended to estimate the risk to ecological receptors associated with contaminants in soils (Calow, 1993; Stephenson et al., 2002; Loibner et al., 2003; Robidoux et al., 2004b). The ecotoxicological assessment of soils is mostly based on the toxicity test with selected organisms. Two complementary approaches are available. The first approach consists in the identification of toxicity thresholds for each relevant pollutant, thresholds that are based on the evaluation of effects of chemical substances on selected organisms representing relevant ecological receptors. The results of these assays are used for setting soil quality standards for each pollutant or pollutant class.Risk assessment tools can be used for this purpose, pre-establishing acceptable levels of risk. The contamination level is based on the comparison of the concentration of contaminants measured in the soil with the standards established from the thresholds. Although field and semi-field information can be incorporated in the higher tier steps, the thresholds are mostly developed from standardised toxicity assays conducted under laboratory conditions following international (e.g. OECD, ISO) or national (e.g. USEPA, ASTM) guidelines. In the second approach, toxicity assays are performed directly with the contaminated media (soil, water, sediment). This alternative, performing the assays with environmental samples, constitutes the method called direct (eco)toxicity assessment (DTA), and is based on modified bioassays.Most regulations have developed soil quality standards based on toxicity assays. However, due to the limitations in the lab to field extrapolation, trends were directed towards the combination of chemical analysis and DTA (Peterson et al., 1990; Torstensson, 1993; Torslov et al., 1997). In this book, both alternatives will be compared. The main difference between both approaches is that in the first case, a reference 'uncontaminated' soil sample is spiked with one or a few chemicals at different concentrations, while in the DTA approach real soil samples are collected at the contaminated site, therefore containing a realistic combination of the different pollutants present in the area, the field sample can be then tested and/or 'diluted' with 'uncontaminated' soil to create a pollution gradient.The toxicity of the spiked or collected/diluted samples is measured and concentration/response relationships obtained in both cases. To understand better this comparison, in this book the term 'toxicity test' will be used for the first approach: toxicity tests with samples spiked at the lab; while the term 'bioassay' will be used for the DTA approach: samples collected at the field.

Understanding Earth -5th Ed by Grotzinger, Jordon, Press and Siever
Product Description:
More than any other introductory physical geology textbook, Understanding Earth is designed to bring the worldview of the working geologist to an audience not only new to this specific field, but in many cases to science in general. Students aren't merely presented with concepts and processes--they come to learn how we know what we know, and how that knowledge impacts their lives as citizens and consumers.

Metric Handbook, Third Edition
Publisher: Architectural Press | pages: 856 | 2008 | ISBN: 0750652810 | PDF | 46,7 mb
Originally devised as a guide for converting from imperial to metric measurements, 'The Metric Handbook' has since been totally transformed into the major handbook of planning and design data for architects. This new edition has been updated to account of the most recent changes to regulation and practice - in particular the increasing emphasis on environmental legislation - to meet the needs of the modern building design professional.
