Granite Powder (GP) and Iron Powder (IP) are industrial byproducts generated from the granite polishing and milling industry in powder form respectively. These byproducts are left largely unused and are hazardous materials to human health because they are airborne and can be easily inhaled. An experimental investigation has been carried out to explore the possibility of using the granite powder and iron powder as a partial replacement of sand in concrete. Twenty cubes and ten beams of concrete with GP and twenty cubes and ten beams of concrete with IP were prepared and tested.

The rapidly growing and gigantic body of stored data in the building field, coupled with the need for data analysis, has generated an urgent need for powerful tools that can extract hidden but useful knowledge of building performance improvement from large data sets. As an emerging subfield of computer science, data mining technologies suit this need well and have been proposed for relevant knowledge discovery in the past several years. Aimed to highlight recent advances, this paper provides an overview of the studies undertaking the two main data mining tasks (i.e.

Young gay and bisexual men are at increased risk for human immunodeficiency virus (HIV) infection. Research suggests that the stress associated with being a stigmatized minority is related to negative mental health outcomes, substance use, and condomless sex. However, interventions aimed at reducing HIV risk behaviors in young gay and bisexual men have failed to address these important variables. The purpose of the present paper is to assist cognitive and behavioral therapists who work with young gay and bisexual men to conduct therapy for stress management and HIV prevention.
