Cellular Digital Packet Data (CDPD) is a new standard, adopted by a consortium of the major United States cellular telephone companies, for data communication with wireless mobile hosts. CDPD is designed to carry data packets using using either IP or CLNP over the current cellular telephone network, utilizing the available idle capacity of the network not used by voice calls. Although much has ...

BACKGROUND Use of cellular telephones is increasing exponentially and has become part of everyday life. Concerns about possible carcinogenic effects of radiofrequency signals have been raised, although they are based on limited scientific evidence. METHODS A retrospective cohort study of cancer incidence was conducted in Denmark of all users of cellular telephones during the period from 1982 ...

the entomopathogenic-fungus-life cycle is associated with the synthesis and secretion of a number of toxic metabolites, including extracellular enzymes and the low-molecular weight compound (toxin). the potential for a successful pathogen relies on the ability to overcome the various host-defence systems. interaction between the fungus, tolypocla-dium (deuteromycetes), its secondary metabolite,...

PURPOSE We investigated the effects of subchronic exposure to radio frequency emitted from a conventional cellular telephone on the testicular function in adult rats. MATERIALS AND METHODS A total of 16 male Wistar rats at age 30 days were randomly divided into 2 groups, including experimental and control groups. The experimental group was exposed to radio frequency emitted from a conventiona...

Advances in the Internet and telecommunications technologies have spurred many research efforts in integrated communication systems which integrate heterogeneous devices (such as desktop phone, cellular phone, PSTN phone or pager) and networks (like the Public Switch Telephone Network, cellular networks, or the pager networks) on top of the Internet and enables communications among any devices ...
