The Group of 77 at the UN is a loose coalition of developing nations, designed to promote its members' collective economic interests and create an enhanced joint negotiating capacity in the United Nations. There were 77 founding members of the organization, but the organization has since expanded to 130 member countries. The group was founded on 15 June 1964 by the "Joint Declaration of the Seventy-Seven Countries" issued at the United Nations Conference on Trade and Development (UNCTAD). The first major meeting was in Algiers in 1967, where the Charter of Algiers was adopted and the basis for permanent institutional structures was begun.[19]

Until the 18th century, the mile used by sailors was the same as a mile on land. Based on the Roman mile Which was designed to represent 1,000 double steps (two strides of a soldier), the statute mile was redefined several times until Elizabeth I decided to set it at 5,280 feet (1,609 metres). -

Mechanisms of Change in the Avian Influenza Virus
Changes in influenza viruses occur all the time. The influenza vaccine administered each year in the United States has to be changed to reflect this antigenic drift (CDC, 2005c; Stephenson, Nicholson, Wood, Zamon, & Katz, 2004). The current vaccine has two influenza A viruses, H1N1 and H3N2, now common in humans but previously avian viruses, and an influenza B virus, which is strictly a human virus (CDC, 2005c). WHO is closely monitoring the antigenic and genetic evolution of the circulating H5N1 virus and has identified changes in the virus during the past year and since it first infected people in 1997 (Li et al., 2004; Tiensin et al., 2005; WHO, CSR, 2005c). So far the changes have been small, but there is growing concern that a major change called "antigenic shift" will occur in the virus structure creating a new virus more easily transmitted to humans.

Some people complain of headaches, fatigue, dizziness or concentration difficulties, symptoms which have been suggested to be triggered by exposure to radio frequency fields. Such complaints have raised concern that certain individuals may be more sensitive than others to electromagnetic energy. This self-reported condition has been referred to as electromagnetic hypersensitivity (EHS).
Studies on electromagnetic hypersensitivity fall mainly into two categories. Some focus on reports from people who say radio frequency fields are making them ill. Others look for an increase in symptoms among populations near mobile phone base stations.
The latter include a 2006 Austrian study that measured radio frequency fields in bedrooms of homes within 600 meters of mobile phone base stations. The residents, who did not know the exact nature of the study, were divided into three groups based on their level of exposure and questioned about 14 symptoms. Reports of three symptoms – headaches, cold hands and feet and trouble concentrating – were significantly more common in the highest exposure group.
Another study compared a group of healthy people exposed to radio frequency fields with a group who were not exposed and found no increase in symptoms. The participants did not know which group they represented. Similar studies found no consistent proof of ability to detect fields, neither in healthy people nor in people reporting symptoms.
In 2005, the World Health Organization conducted a workshop on radio frequency exposure. The consensus was that althou-
