In recent years interest in ITS (Intelligent Transport Systems) technology has been growing, because it is thought that ITS can solve problems such as traffic jams and traffic accidents. Communication between roadside base stations and vehicles is a critical element of an ITS. In this paper, we describe the road-vehicle communication (RVC) system using ROF technology and software radio. These s...

Background. Cell-phone usage has increased dramatically over the last decade, along with a rising public concern over the health effects of using this device. The association between cell-phone usage and hypertension has not been examined before. Methods. We analysed data from 21,135 adults aged ≥18 years who participated in the 2008 National Health Interview Survey. Based on reported cell-phon...

Communicating complex health-care and long-term care information clearly, quickly and in ways your clients can truly understand is a major challenge for aging-services providers. This brief focuses on oral communication, discussing why Medicare and other health-care information is so hard to talk about and offering tips you can use to help improve your communication with clients.

F ar from settling the question of whether cell phones cause cancer, the latest pronouncement by the World Health Organization that cell phones could “possibly” be carcinogenic has left a wake of confusion and consternation. In July ’ s The Lancet Oncology , the WHO ’ s International Agency for Research on Cancer (IARC) announced that it had classifi ed radiofrequency (RF) electromagnetic fi el...

Background: Infertility is defined as inability to conceive after a year of sexual intercourses without the use of contraceptives. In half of the cases the causative factor is the male. Males are exposed to the effect of various environmental factors, which may decrease their reproductive capabilities. Phone electromagnetic power is very small, only a few hundredths of a microwave oven, but bec...

In th is paper we propose an extension to the classical RASTA technique. The new m ethod consists of classi­ cal RASTA filtering followed by a phase correction op­ eration. In th is m anner, the influence of th e commu­ nication channel is as effectively removed as w ith clas­ sical RASTA. However, our proposal does not introduce a left-context dependency like classical RASTA. There­ fore the n...

introduction:  the  use  of  mobile  communication  systems  has  dramatically  increased  over  the  past  decade. although many studies have been performed to determine the effect of radio frequency (rf) but  less attention has been paid to the possible biological impact of exposure to extremely low frequency  (elf) components.   the objective of this study is two folds. one is to design the ...

Background & objectives: Cell phone microwave (MW) is one of the most harmful physical agents in modern society. This study was designed to determine the effects of exposure to cell phone microwaves on mice sperm morphologic indices. Methods: Animals were divided into two groups including: Microwave (MW) (n=6; exposed to 950-MHz cell phone MW with 5 W output power density and 200 KHz modulatio...
