Ternyata Radiasi Ponsel Bantu Cegah Kepikunan !

DI tengah-tengah perdebatan yang menyebutkan radiasi ponsel memicu tumor otak, ada satu hasil studi terbaru yang berlawanan.Radiasi ponsel rupanya mampu meningkatkan kemampuan memori otak.
Setidaknya inilah hasil studi yang diuji coba pada 96 ekor tikus. Gelombang radiasi yang dipancarkan ponsel disebut- sebut bisa meningkatkan aktivitas otak, bahkan melawan penyakit alzheimer, yaitu kepikunan yang disebabkan menurunnya fungsi saraf otak yang kompleks dan progresif karena otak kekurangan gizi. "Temuan ini sungguh mengejutkan, paparan radiasi ponsel rupanya melindungi memori otak tikus yang memperlihatkan gejala alzheimer," kata ketua studi Gary Arendash dari Florida Alzheimer's Disease Research Center. Seperti dilansir LiveScience , Kamis (7 /1 /2010) , studi ini dengan sengaja memberikan paparan radiasi ponsel secara terus menerus pada tikus yang memiliki gejala alzheimer. Gelombang elektromagnetik dari ponsel yang didekatkan pada tikus terbukti ampuh menghilangkan kadar beta- amyloid, yaitu protein yang berkaitan erat sebagai pemicu penyakit alzheimer. Kelompok tikus normal dengan yang memiliki gejala alzheimer sama-sama diberikan paparan radiasi ponsel dalam jangka waktu dua setengah jam per hari selama tujuh hingga sembilan bulan. Pada hasil pemindaian otak tikus, terlihat bahwa gumpalan beta-amyloid yang juga biasa disebut plak pada otak berangsur-angsur menghilang setelah terkena paparan radiasi ponsel. Para ahli berspekulasi bahwa radiasi ponsel meningkatkan temperatur otak, sehingga menyebabkan sel otak melepaskan plak 'kotor' tersebut. Mereka pun memprediksi, efek yang sama mungkin juga terjadi pada manusia. Jika benar demikian, radiasi ponsel dapat dimanfaatkan untuk mencegah dan memerangi penyakit tertentu pada manusia. Kendati demikian, penelitian pada tikus tidak selamanya dapat langsung diterapkan pada manusia, sehingga diperlukan studi lebih mendalam untuk membutikannya.

Customizing ones cellular phone has become the fashion of the day. Most people who use cellular phones look upon their gadgetry as personal accessories. Once this gets into the psyche, they feel a need to make it unique or stylish in their own way so as to make the cellular phone or mobile phone reflect their personality.

Since the majority of the populace who use cellular phone is predominantly young between 15-45 years, their tastes vary widely, affected by localization factors like country, culture, music, career, education etc. This varied taste has given rise to a great demand in variety and design of these accessories.

A mobile phone can have two kinds of accessories – hardware and software. The hardware accessories cover the facia, earplugs and all other attachments that are physically visible. The software consists of wallpapers, screensavers, ringtones, games etc. The software being the most creative mobile phone accessory, it becomes more customizable and replaceable at a lower cost. The software is also called content.

In this article we are going to discuss wallpapers in detail. Wallpaper can be described as a graphic description which forms the background of a mobile phone’s display unit. A lot of wallpapers are available depending on the model of the mobile phone in free and paid categories over the internet. In personalizing one’s mobile phone by the use of wallpaper, a lot of care should be taken. Keep in mind the following factors while choosing one:

The wallpaper that you should be choosing should have aesthetic and design appeal and should suit your personality so that it portrays the correct image of you. Always remember that your mobile phone will be used mostly by you and is primarily your communication tools, so the wallpaper you choose should be mellow and motivating so that it has a visual effect of reducing stress combined with a small pep appeal. Wallpaper today is an indispensable part of your mobile phones life. So choosing it carefully is important.

Firstly find out the resolution supported by our mobile phone model. Locate content in this resolution only. You can download the content in no time, but make sure you get at least 2-3 kinds of wallpapers or themes. Usually, no mobile phone owner likes to keep a single wall paper for more than a few days, downloading more than one will only help add spice to life. Swapping content within your mobile phone’s domain is very simple and does not take any time. This swapping instills change in an otherwise boring and habitual life.

The mobile phone market is warring and writhing in competition today. Design, aesthetics, features, weight, color etc are all features that keep constantly changing in this competitive world. Content for new, newer and newest phones is also growing by the day at a pace at which the developers can produce. In a bid to add entertainment and to make using a mobile phone easier, newer and newer content is being developed by the day. The visual appeal content mainly consists of only through wallpapers and screensavers.

VOIP Broad Band Phones

Voice on Internet Protocol (VOIP) Phones are referred to as just Broad band Phones. The main function of a Broad Band phone using VOIP is to convert voice data (analog) into digital data for transmission over the Internet. They are connected to the high speed internet through computers to enable voice communication. By this innovation VOIP Broad Band Phones have turned internet into a carrier for free phone calls, by going around the normal phone companies.

VOIP Broad Band phones are a product of revolutionary technology which can change the entire way people speak to each other around the world. There are a few VOIP service providers who are growing by the day now, and major phone companies are busy setting up shop in various markets around the world with different calling plans with free VOIP Broad Band phones bundled in. FCC and other regulatory bodies all over the world are fervently busy investigating and predicting the ramifications and future risks in usage of VOIP Broad Band phones and their prevention.

We will look into the basic technology of VOIP Broad Band phones working and it’s potential in replacing the traditional phone systems.

The most intriguing feature of VOIP Broad Band phones is that they look just like their predecessors with cradle, buttons and handsets. A normal telephone is connected to wall socket using a RJ-11 connector, whereas VOIP Broad Band phones are connected to your computer or router using a RJ-45 connector. All VOIP Broad Band phones come with preloaded software to handle any IP calls. Technology is already moving towards Wi-Fi VIOP Broad Band phones which can used to make calls from any Wi-Fi hotspot. Are you thinking of replacing your cellular phone???

In addition to usage of VIOP Broad Band phones, VOIP can also use ATA sets i.e. simple telephone like boxes that connect to your computer and convert your analog voice data into digital signals. VOIP also connects computer to computer calls where you do not need any extra hardware apart from a standard computer system with headphone and internet connection. Except for what you pay for your internet connection, there is no extra cost involved in both these options. VOIP Broad Band phones are dedicated instruments used only for making calls over VOIP.

If you want to have a go at VOIP Broad Band phones features, you can sample the free versions on the internet to check out connectivity and sound quality. Once place I can suggest is the latest version of Yahoo Messenger Version 7.0 which is Voice enabled. You can make computer to computer calls using yahoo messenger. It is very easy to implement, just try it out. One other place you could take a look at is www.skype.com. VOIP Broad Band phones are certainly here to stay despite the internet sops and other devices available.

If you are a long distance caller you could be involuntarily making VOIP calls without using a VOIP Broad Band phones and at normal cost. Most phone companies around the world are trying to reduce their bandwidth by routing a few thousand calls through circuit switches onto an IP gateway. On the receiving end, they just reverse the process, somewhat similar to multiplexing.

Given sometime all the current phone technology involving circuit switched networks will be replaced by packet switching technology. VOIP technology is efficient on financial and infrastructure needs, it costs less and takes lesser infrastructure and is more efficient. VOIP Broad Band phones have made their way into most corporate houses; it is only a matter of time before they barge into our homes.

More than 5 million households will be using VOIP Broad Band phones by the end of 2006 says the Forrester Research Group. One cannot escape the VOIP Broad Band phones as a means of communication.

VOIP Broad Band phones score on the basis of cost and flexibility. It can be said that they are free to use, unless you use your broadband connection only for your VIOP Broad Band phones. You can virtually call from anywhere in the world where u can access a broadband internet connection. You can carry your VOIP Broad Band phones anywhere on use your laptop to make PC to PC calls.

VOIP companies are offering rate plans similar to cellular phones for customers who want only VOIP Broad Band phones. They vary anywhere from $30 to $80 per month. They are also offering a lot of freebies including free VOIP Broad Band phones to go with them which make these rates further economical.

Nge-Charge Ponsel Dengan Celana Jeans !

TIM dari Stanford University mengembangkan cara baru untuk mengisi ulang baterai ponsel, yaitu dengan aliran listrik dari pakaian yang Anda kenakan.
Dengan temuan ini, saat pengguna ponsel bepergian, mereka tak perlu kerepotan mencari stop kontak untuk mengisi ulang baterai ponsel. Cukup menyambungkan kabel dari celana jeans atau kemeja yang dipakai ke ponsel, maka baterai ponsel pun langsung terisi arus listrik. Namun sebagai gantinya, sepanjang malam sebelum bepergian pengguna harus mengisi pasokan listrik pada pakaian hingga penuh. Yi Cui dan timnya bekerja keras mengubah bahan kain dan polyester biasa menjadi bahan tekstil penghantar energi yang berfungsi sebagai charger untuk isi ulang baterai ponsel. "Temuan ini merepresentasikan perkembangan materi jenis baru dengan berbagai fungsionalitas baru seperti fleksibilitas, elastisitas, dan lain sebagainya. Bahan tersebut bisa digunakan untuk beragam aplikasi dan rancangan yang sebelumnya tidak mungkin dilakukan dengan teknologi tradisional," kata Yi Cui seperti dikutip dari TG Daily , Jumat (22 /1 /2010). "Pakaian olahraga berbahan khusus, penyimpan energi portabel, serta sistem monitoring kesehatan yang ditanam, merupakan contoh aplikasi baru yang gencar dikembangkan," tambahnya. Dalam temuannya ini, Yi Cui menggunakan 'tinta' berbahan karbon nanotube tunggal. Tinta ini kemudian diaplikasikan pada bahan katun dan serat polyester untuk pakaian, sehingga mengubahnya menjadi bahan ajaib yang bisa menyimpan listrik. Yi Cui mengklaim, serat bahan ini memiliki fleksibilitas dan elastisitas seperti bahan katun dan polyester biasa. Bahan ini pun sama seperti bahan pakaian pada umumnya yang bisa dicuci dan dikeringkan berulang kali.

CELL PHONES

The amazing technology cell phones have these days is surprisingly growing and developing.

Cell phones started out as an idea for a mobile phone that can be used from a car, within a given range. This was happening back in 1947. Since then, their purpose was achieved and greatly exceeded.

The mane comes from the word cellular combined with the normally used word, phone. Cellular because their whole technology is based on cells of signal. Each cell has as a centre a transmitter that assures the mobility and the great range, almost worldwide, of mobile phones. These transmitters are placed in such a way so that they can form a network with absolutely no uncovered spaces. Not all portions have been covered, but the civilized and populated locations all have mobile phone operators and coverage.

Nowadays, mobile phones try to include as many technological areas as possible. There is no cell phone out there that is only a cell phone. From watching TV to playing games, taking pictures and making movies, from real music to color display, they have it all. Some phones even have Windows from mobile on them, just like PCs. Others can actually compete with game consoles like Nintendo because they are kind of a miniature game console themselves.

The extreme competition out there makes developers want to achieve more and more with their phones. Japan has always been a pioneer in the cell phone industry, they had TV and camera phones long before they appeared in America and Europe. Japanese manufactures and worldwide producers try every day to come up with new things for a cell phone, following a fixed goal: the perfect phone that can stand for all multimedia and communication devices out here, a phone that combines everything from communication to utility and work.

So, in the near future the cell phone might offer us a great surprise. How knows, they may try and develop some kind of holographic graphics. No matter what the next step is, the industry is certainly improving every minute, even as we speak and cell phones have a bright future ahead of them.
