Index of harm: a measure for comparing occupational risk across industries

Description: This areport explores the implications of an index-of-harm methodology that compares occupational risks among workers exposed to radiological and nonradiological harms. It extends the work of the International Commission on Radiological Protection (ICRP) by considering American rather than European and Japanese industry groups, by treating the relative importance of various occupational harms as a parameter rather than an arbitrary constant, and by identifying several ways in which both the met… more

Geologic carbon sequestration as a global strategy to mitigate CO2 emissions: Sustainability and environmental risk

Description: Fossil fuels are abundant, inexpensive to produce, and are easily converted to usable energy by combustion as demonstrated by mankind's dependence on fossil fuels for over 80% of its primary energy supply (13). This reliance on fossil fuels comes with the cost of carbon dioxide (CO{sub 2}) emissions that exceed the rate at which CO{sub 2} can be absorbed by terrestrial and oceanic systems worldwide resulting in increases in atmospheric CO{sub 2} concentration as recorded by direct measurements … more

Model Components of the Certification Framework for Geologic Carbon Sequestration Risk Assessment

Description: We have developed a framework for assessing the leakage risk of geologic carbon sequestration sites. This framework, known as the Certification Framework (CF), emphasizes wells and faults as the primary potential leakage conduits. Vulnerable resources are grouped into compartments, and impacts due to leakage are quantified by the leakage flux or concentrations that could potentially occur in compartments under various scenarios. The CF utilizes several model components to simulate leakage scena… more

Analysis and Classification of Mammography Reports Using Maximum Variation Sampling

Description: Currently, no automated means of detecting abnormal mammograms exist. While knowledge discovery capabilities through data mining and data analytics tools are widespread in many industries, the healthcare industry as a whole lags far behind. Providers are only just beginning to recognize the value of data mining as a tool to analyze patient care and clinical outcomes. The research conducted by the authors investigates the use of genetic algorithms for classification of unstructured mammography r… more

Unconventional gas sources. Volume 4. Geopressured brines

Description: The following topics are covered: study objectives, regional geology and prospect evaluation, reservoir engineering, drilling and well costs, production and water disposal facilities, pressure maintenance, geothermal and hydraulic energy assessment, operating expense, economic evaluation, environmental considerations, legal considerations, and risks analysis. The study addresses only sandstone brine reservoirs in the Texas and Louisiana Gulf Coast onshore areas. (MHR)

EVALUATING THE RISK OF AIR POLLUTION TO FORESTS IN CENTRAL AND EASTERN EUROPE

Description: Foliar damage to trees by air pollution in Central and Eastern Europe has been a major scientific and political issue. Emissions of toxic gases such as sulfur dioxide and nitrogen oxides can have wide-ranging effects on local and regional vegetation that can be compounded by other environmental stresses to plant growth. Since uptake and physiological effects of these gases on tree leaves are largely mediated by stomata, surrogate methods for estimating pollutant conductances into leaves and for… more
