Obsessive-compulsive disorder (OCD) occurs with high prevalence, and the drugs used to treat OCD are limited in efficacy and have side-effect issues. The discovery of improved medicines for OCD has been hampered in part by the lack of predictive in vivo models. This unit provides a brief overview of two methods that might have such predictive utility. Marble burying and nestlet shredding are tw...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

The paper describes the effect of marble dust on plants in and around Vishwakarma Industrial Area (VKIA) Jaipur, Rajasthan (India). Trees species growing in and around VKIA area were selected and various morphological characteristics were studied such as leaf area dry weight ratio (LADWR), Dust retaining capacity (DRC) and Chlorophyll content. In the study the effects of marble dust on selected...
