what is the effects of mobile phones on human body

Mobile or cell phones are now a days an integral part of modern telecommunications in every individual life. In many countries, over half of the population use mobile phones and the mobile phone market is growing rapidly. Saudi Arabia rank first among the countries of the gulf region with highest proportion of mobile users, a study conducted by United Nations Conference on Trade and Development (UNCTAD). In gulf countries, Oman ranked second, followed by Kuwait and the UAE.
Besides the number of cell phone calls per day, the length of each call and the amount of time people use cell phones are important factors which enhance the health related risk. In 2011, International Agency for Research on Cancer (IARC) classified mobile phone radiation possibly carcinogenic, means that there “could be some risk” of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted.Mobile phones emit radio frequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radio frequency energy a mobile phone user is exposed depend on many factors as the technology of the phone, the distance between the phone and the user, the extent and type of mobile phone use and the user’s distance from cell phone towers.  The long-awaited results of a US$25 million National Institutes of Health " study on the effects of cellphone radio-frequency radiation exposure" on animals is out, and the results are mixed.They showed a higher risk of tumors, DNA or tissue damage, and lower body weight in some groups of rodents, but no obvious ill effect in others and no clear implications for human health.While an increased risk of brain tumors from the use of mobile phones is not established, the increasing use of mobile phones and the lack of data for mobile phone use over time periods longer than 15 years warrant further research of mobile phone use and brain cancer risk. In particular, with the recent popularity of mobile phone use among younger people, potentially longer lifetime of exposure.Scientists have reported adverse health effects of using mobile phones including changes in brain activity, reaction times, and sleep patterns. More studies are underway to try to confirm these findings. When mobile phones are used very close to some medical devices (including pacemakers, implantable defibrillators, and certain hearing aids) there is the possibility of causing interference with their operation. There is also the potential of interference between mobile phones signals and aircraft electronics. Some countries have licensed mobile phone use on aircraft during flight using systems that control the phone output power.
The American Cancer Society (ACS) states that the IARC classification means that there could be some risk associated with cancer, but the evidence is not strong enough to be considered causal and needs to be investigated further. Individuals who are concerned about radio frequency exposure can limit their exposure, including using an ear piece and limiting cell phone use, particularly among children.

you can lose weight

Exercise can certainly help you lose weight by burning calories and building muscle. But, doing just push-ups — even daily — is unlikely to be rigorous enough to burn enough calories to lose a lot of pounds. Push-ups alone also fail to stimulate total-body muscle gains that raise your metabolism and make you a lean machine. To lose weight, the American College of Sports Medicine recommends at least 250 minutes of moderate-intensity cardio exercise weekly. Moderate-intensity exercise is equal to brisk walking or playing a game of doubles tennis. It's unlikely you could fit in 250 minutes of push-ups weekly, and even if you could, this repetition would lead to join pain from overuse. Push-ups are a functional exercise that build stamina and strength in many major muscle groups. Include them as a part of your weight-loss regimen, but not as the sole exercise. Push-Ups Impact on Your Weight Although other factors do come into play, weight loss essentially comes down to crea

Dhokra The Traditional Art of Metal Casting

The name 'Dokra' or ‘Dhokra’ was used originally to indicate a sect of metal craftsmen who well were known for their metal craft. Dokra now refers to a metal craft which is tribal in origin. It is mainly found in the tribal areas of Madhya Pradesh, Orissa, West Bengal and Andhra Pradesh. In this metal craft the craftsman firstly subcultures a wax model of the object he wants to make. Then he makes a mould of clay and pours molten metal into a hole in the mould, then the wax melts and the clay is broken away to bring out the metal object which is then smoothed an polished to perfection. This is also know as the lost wax procedure or “cire perdure”. Dokra art mainly produces figurines of Gods, Goddesses and religious animals and birds. Dokra art has a rustic and antique finish which makes this unique and appealing. Though the Dokra artists are untutored in traditional institutions the Dokra craftsmen posses huge repertoire of creativity and artistic sagacity. Dokra art is
