Understanding the interconnectivity of organisms among different habitats is a key requirement for generating effective management plans in coastal ecosystems, particularly when determining component habitat structures in marine protected areas. To elucidate the patterns of habitat use by fishes among coral, seagrass, and mangrove habitats, and between natural and transplanted mangroves, visual...

The attractiveness of both ballistic missiles and weapons of mass destruction (WMD) to various actors throughout the world represents a serious threat to U.S. security. These weapons and delivery systems are popular in part because they are highly visible symbols of military prowess.

Having personally witnessed the destruction at the World Trade Center on 11 September 2001, this paper presents my personal feelings and observations as an observer of both disaster and terror. Aside from the unimaginable horror as a result of the carnage, a feeling of helplessness was particularly prominent due to the inability to be able to care for casualties since most victims were fataliti...

Any attempt to characterize a bacterial community and their functional genes coding for enzymes of the nitrogen cycle is faced with its extreme biodiversity. Novel techniques, based on PCR amplification of target genes in DNA from environmental samples, have been developed for characterizing both cultured and as yet uncultured bacteria in the last few years. Computer-based assignment tools have...

Background & Aim: In the present research, we investigated phytochemical characteristics of two important species of Verbascum genus. Enormous reconnaissance and field surveys were conducted to identify the most important natural habitats of Verbascum species in Kohgiluyeh va Buyerahmad province, southern Iran. Experimental: The aerial parts of Verbascum songaricum a...

The tragic events of 9/11 and the concerns about the potential for a terrorist or hostile state attack with weapons of mass destruction have led to an increased emphasis on risk analysis for homeland security. Uncertain hazards (natural and engineering) have been successfully analyzed using probabilistic risk analysis (PRA). Unlike uncertain hazards, terrorists and hostile states are intelligen...
