The sped up feature of day-to-day life and increasing demand for perfection in maximum possible spheres of life along with the ultimate desire of comfort and ease has lead us to the heights of development in contemporary times. All these factors are not only the driving forces of economic development round the globe but also the speedometers of standard of living in a particular region, country or area. The only thing that deploys the essence of this development is the unavailability of sustainable growth. On one hand where we’re touching the skies of mega and cellular technology, we’re losing list of essentials, i.e. health.

Setting cellular technology the theme of discussion let’s have an overview of it. One of the major examples of cellular technology, i.e. the mobile phone system is in question for a long time. Both the technology concerns and the social scientists had agreed to differ. And it’s still a vexed question. Cellular phone services being the easiest and fastest modes of communication have billions have billions of subscribers round the world. Even in developing countries where a major part of population is striving hard to satisfy basic needs, i.e. food and clothing, use of mobile phone have become a necessity for them.

Mobile phones use cellular technology whereby the regions are covered by radio waves using a base station antenna as a transmitter and the handset as receiver. Cellular technology is the better option in a sense that it provides better coverage, increased capacity and reduced power usage. Both the digital GSM and the CDMA systems share this base. The point that’s been raised more by the social scientists and health concerns is the effect of radio waves on health. These radio waves are emitted by both handsets and base stations.

With reference to the handsets, the effect of radio waves emitted by the cell phone communication, especially with specific reference to human health, can be categorized as, thermal, non thermal and genotoxical. Thermal effect is one whereby the electromagnetic field of radio waves induces polar molecules that generates dielectric heat letting the live tissues die. For instance some part of head, while receiving the message through radio waves if happens to experience increased temperature can have damaged nerve fibers. (more…)

For most women, one week a month brings mood swings, cravings, bloating and general irritation. Your period as part of the female reproductive cycle serves an important purpose. It cleanses the uterus of unnecessary lining when another month goes by without getting pregnant. But if you aren’t trying to become pregnant, is it really necessary to have a period?

Understanding the System
The female reproductive system is a cycle. Every 28-30 days on average, a female’s body thickens the lining of the uterus, releases an egg to be fertilized and then waits for that egg to land on an implant in the uterus to begin a pregnancy. If the egg doesn’t arrive, the lining is shed through the period, and the cycle begins anew.

When birth control pills were first developed in the 1960s, they were designed to give the female body twenty-one days of active hormones and then seven days of sugar pills. When the body was off the active hormone, it went through withdrawal bleeding. This twenty-eight day cycle mimics the body’s natural rhythms, and the arrival of a woman’s period every month let her know that she was not pregnant, despite the use of the pills. But the body is not preparing for pregnancy while on the pill, there is no actual thickening of the lining since the hormones prevent it. (more…)

Recent recall notices have blared across television sets and websites. Stores such as Wal-Mart, Target, and Toys R Us prominently display recall notices to be sure no consumer has missed an important announcement. When a product is recalled, there is often a rush to return items to stores or condemn the manufacturer, but are all recalled products actually dangerous?

Recalls
Most car owners, provided they’ve purchased a new car, have received recall notices in the mail at one time or another. Perhaps the windshield wiper switch was faulty or a latch was poorly designed. Recalls are actually more common than we realize on electronics and other consumer goods. If you fail to send in the warranty information (and really, who does?) then you simply won’t be alerted to any small problems.

Sometimes, however, you don’t need a letter to find out about a recall. Almost a decade ago, Firestone Tires and Ford underwent a huge fiasco with blowouts and resulting rollover accidents in SUVs. Ultimately, Ford and Firestone replaced all of the potentially defective tires for customers as the circumstances were so substantial.

Food recalls are also widely known. E Coli, Mad Cow Disease and other bacteria contamination has caused wide spread recalls. At the moment Totino’s Pizzas have been recalled as the pepperoni used since July might contain E Coli. In recent history, cheeses and vegetables have had similar effects. Certain brands of dog and cat food were included in another huge recall this year as they were found to be causing injury and death to pets. (more…)
