Island nations may be beautiful, but their isolation makes them vulnerable to outside forces that increasingly threaten their survival. Rising sea levels linked to global warming could submerge some altogether. Tuvalu, a West Pacific nation whose peak height rises just 5 meters over sea level, could be uninhabitable within 50 years, some experts say. A similar fate could also doom the Maldives, the Marshall Islands, Kiribati, and Tokelau. Of all

history of vaccines, including who discovered them and their usage through the present day. Vaccines are one of the ways humans have learned how to protect themselves from dreaded diseases.

prokaryotes consist of millions of genetically distinct unicellular organisms. A procaryotic cell has five essential structural components: a genome (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer which may or may not be an inherent part of the wall (1). Functional aspects of procaryotic cells are related directly to the structure and organization of the macromolecules in their cell make-up, i.e., DNA, RNA, phospholipids, proteins

West Nile Virus In recent years, every summer, the threat of West Nile (WN) virus has become the scourge of the temperate regions of Europe and North America. (Abramovitz, 2004) The virus presents a threat to the human and animal population -- especially the bird population. Symptoms of WN viral infection range from mild fevers and aches, to encephalitis (inflammation of the spinal cord and brain). The latter can be fatal.

Corporate Governance Sustainability During the last several years, the issue of corporate governance has been increasingly brought to the forefront. This is because the financial crisis exposed the weaknesses of the current system by: failing to protect the interests of stakeholders. In response to these challenges, various reports have been reexamined. One of the most notable is the King Report of 2002. It identified several different criteria that can be used
