Sunday…

Well its Sunday again and seriously I don’t really like Sunday because tomorrow its going to be the beginning of another crazy week. Anyway I came online just to check up on some stuff; primarily marshalling signals for airplanes, also to log on onto MSN to get some updates, update me Facebook and at the same time download a few songs. Just wanna keep my music library up to date.

Anyway this is that small little devil that got me come look for more info about it.

(Sorry I can’t insert a link here. So I pasted it instead)

Looks cool. The thing that got me attracted to it is because it has WiFi and also GPS. 2 features that I am looking for in a phone. I know I know, there are many others out there that has both this functions but then I have been using Nokia phone since the beginning of time, so I thought I would stick with Nokia. Am still not ready for the crossover to over breed yet. >.<

But anyway won’t be getting this devil I guess. First thing I wanna buy is a shade! ^^, Been going around Langkawi going into various eye-wear shop looking at various design hoping to find a cool one. ^^,

Anyway I guess I will stop here. Till I am back again, have a great week ahead of you!

How to Give CPR To Your Electronic Gadget

How to give CPR to your electronic device and revive it in case it fell into the water and drown? Here’s a quick tip :

I personally think this method will work if your device drops into the water. But if its other than water, e.g Coke, Wine , seawater and etc., it is very likely that this method won’t work. Due to the fact that this kind of liquid contains dissolved molecule which when the water evaporate, it is left behind and it can really hurt your circuit board. So anyone is up in drowning their phone or maybe a laptop? Anyone? Any takers? So we can test to see if the method works. I guess not. But you know what to do when your phone drowns.

The 11pm Radiation Attack!!

Help!!! We are under attack!!!! @.@” Nah just kidding.

But I guess many of you guys out there did receive a text message asking you to turn off your mobile phone at 11pm due to some high radiation activity right? I personally did not receive such sms but when I hear this news I was intrigued to find out more about phone radiation. So as usual I go to my information guru which is the Wikipedia and HowStuffWorks

When I heard of this news for the first time, I think to myself it is actually quite useless even if you turn off your phone, because even now when you are reading this post you are actually being bombarded by tonnes of radio waves, besides those from your mobile phone. And lets not forget that our phone receives and emits signals. So even if you turn off your phone, although it will not transmit anymore, but those signals that our phones receives comes from the base stations(which are antennas we see everywhere). So even if you switched off your phone, you are still being bombarded by the radio waves emitted from the base stations. Although we do know that the intensity of the radiation decreases when we are further away from the antennas, but hey look, look how wonderful our signal coverage is these days. And how many telecommunications networks are out there for us. I just personally think we are in a very huge radiowave oven!

Anyway, after I did some reading, I found out that our phone manufacturers measure the amount of radiation emitted by our phone according to this Specific Absorption Rate(SAR) standard which is measured in W/kg over an average amount of tissue. In which SAR is defined as a measure of the maximum rate at which radio frequency (RF) energy is absorbed by the body when exposed to radio-frequency electromagnetic field.

So here’s a little knowledge about phone radiation for Dummies’!

The concerns with this radiation is that the effect of this absorbed energy is dielectric heating, in which any dielectric material (such as living tissue) is heated by rotations of polar molecules induced by the electromagnetic field. In the case of a person using a cell phone, most of the heating effect will occur at the surface of the head, causing its temperature to increase by a fraction of a degree. In this case, the level of temperature increase is an order of magnitude less than that obtained during the exposure of the head to direct sunlight. The brain’s blood circulation is capable of disposing of excess heat by increasing local blood flow. However, the cornea of the eye does not have this temperature regulation mechanism and exposure of 2-3 hours’ duration has been reported to produce cataracts in rabbits’ eyes at SAR values from 100-140W/kg, which produced lenticular temperatures of 41-41°C. Premature cataracts have not been linked with cell phone use, possibly because of the lower power output of mobile phones.Although it has been claimed that some parts of the human head are more sensitive to damage from increases in temperature, particularly in anatomical structures with poor vasculature, such as nerve fibers.

So now we know when we put our mobile phone to our ears, we are actually cooking our brain. But the current available scientific evidence does not demonstrate any adverse health effects associated with the use of mobile phones. However, that doesn’t mean that the potential for harm doesn’t exist.

We have also heard about mobile phone usage linked to cancer and in 2006 a large Danish study about the connection between mobile phone use and cancer incidence was published. It followed over 420,000 Danish citizens over 20 years and showed no increased risk of cancer. The German Federal Office for Radiation Protection (BfS) consider this report as inconclusive.

So in order to investigate the risk of cancer for the mobile phone user, a cooperative project between 13 countries has been launched called INTERPHONE. The idea is that cancers need time to develop so only studies over 10 years are of interest. And still till now, there are no adverse health effect related to mobile phone usage.

But if you are worried, here is how you can protect yourself :

# Use a hands-free headset.
# Use a phone that places the antenna as far away from you as possible.
# Extend the antenna during use.
# Limit calls inside buildings.
# Use the phone in open spaces as often as possible.
# Limit use by children.

And listed are the top ten lowest-radiation cell phones

Manufacturer and model SAR level
(digital)
1. LG KG800 0.135
2. Motorola Razr V3x 0.14
3. Nokia 9300 0.21
4. Nokia N90 0.22
5. Samsung SGH-G800 0.23
6. Samsung Sync SGH-A707 0.236
7. Nokia 7390 0.26
8. Samsung SGH-T809 0.32
9. Bang & Olufsen Serene (Samsung SGH-E910) 0.33
10. Motorola Razr2 V8 0.36

And the top ten highest-radiation cell phones

Manufacturer and model SAR level
(digital)
1. Motorola V195s 1.6
2. Motorola Slvr L6 1.58
3. Motorola Slvr L2 1.54
3a. Motorola W385 1.54
4. Motorola Deluxe ic902 1.53
4a. T-Mobile Shadow (HTC) 1.53
4b. Motorola i335 1.53
5. Samsung Sync SGH-C417 1.51
5a. Motorola V365 1.51
5b. RIM BlackBerry Curve (AT&T) 1.51

So as a conclusion, Motorola phones will be definitely out of my wish list! Which is quite surprising to me because I thought Nokia would top the highest-radiation chart instead! Since people are saying that Nokia emits lots of radiation. And in my opinion radiation is everywhere, so I guess even if we are to turn off our mobile, it will reduce the risk of exposure but nonetheless the base stations are still out there. Or maybe this whole thing about the sms is just a scam?? A scam by the telecommunications company so that we sent sms to our loved ones and they make money through the sms sent?? Perhaps?? Or maybe a sabotage by some group of people? They asked people to turn off their mobile so there will be no phone calls made or sms sent, so the telecommunications company lose money? Perhaps?
