Decision support systems (DSSs) are potentially valuable tools for assessing the economic and ecological impacts of alternative decisions on aquaculture production. This report discusses the latest design, functional modules, and application areas of POND©, a decision tool that has been developed to allow analysis of pond aquaculture facilities by the use of a combination of simulation models a...

This paper deals with use of pond ash and RBI Grade 81 for improvement in CBR values of clayey soil and grade-III materials used for base course of flexible pavement. The pond ash is a thermal power plant waste and RBI Grade 81 is chemical soil stabilizer. The geotechnical properties like Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Unconfined Compressive Strength (UCS), CBR value...

Aerial photography was conducted in the high Arctic Ocean during a Chinese research expedition in summer 2010. By partitioning the images into three distinct surface categories (sea ice/ snow, water and melt ponds), the areal fraction of each category, ice concentration and the size and geometry of individual melt ponds, are determined with high-spatial resolution. The ice concentration and mel...

STUDY OBJECTIVE To test the hypothesis that individuals chronically noncompliant with antituberculous chemotherapy are vectors for ongoing transmission of the disease in the community. DESIGN Cohort study. SETTING A large public hospital with a tuberculosis detention unit for patients with repeated and prolonged nonadherence to therapy. PATIENTS Mycobacterium tuberculosis isolates from pa...

OBJECTIVES Many adolescents admitted to detention facilities have serious mental and physical health problems. Little is known about policies for the delivery of mental and physical health care in these settings. Our objective was to describe current health care policies in U.S. detention facilities. METHOD Telephone interviews were requested from 83 juvenile detention facility administrators...

The presence of melt ponds on the surface of Arctic sea ice significantly reduces its albedo, inducing a positive feedback leading to sea ice thinning. While the role of melt ponds in enhancing the summer melt of sea ice is well known, their impact on suppressing winter freezing of sea ice has, hitherto, received less attention. Melt ponds freeze by forming an ice lid at the upper surface, whic...

Computer simulation models are a useful tool in planning, enabling reliable yet affordable what-if scenario analysis. Many have been proposed and used for urban planning management. Still, there few modeling options available the purpose of evaluating effects various stormwater control measures (SCM), including LID (low-impact development) controls (green roof, rain garden, porous pavement, rai...
