Gimme a Green Cell Phone
No, I'm not talking about LG's green-hued Mint Chocolate phone (although, if I were in the market for a new Chocolate, the green Mint would be my preference). What I'm actually referring to is a new type of technology that the wireless industry is testing out that will use alternate energy to power cell phones. Cell companies have "heard the call" of millions ofgreen energy advocates and, in response, have begun working on ways to change the methods they have had in place for years.
There is a variety of ways that the cellular industry can utilize in place of their current mode of providing this convenience to its users. They are realizing that cell phone towers may have the ability to be powered by wind turbines. For those who don't know, turbines are any of various machines in which the kinetic energy of a moving fluid, such as water, steam, or gas, is converted to rotary motion.
These same cell towers could also be operated through the use of solar panels, making use of the energy of the sun to power up the cell phones. Antennas could also receive their back up energy from hydrogen fuel cells and computer equipment could be cooled through geothermal methods.
The wireless industry has come to realize, whether through their own conscience or through the voices of millions who care about the earth's current deterioration and eventual demise, all of the negative effects that its current methodology has had on environmental factors, and they seem to have a desire to alter their techniques in order to do their part to improve the condition of our world. However, my skepticism prevails, and it almost seems as if their concerns still reside more so in what impact this alteration with have financially. In other words, if this will save them money, they are more interested in attempting it.
The ideas that they have for this change over are still in the experimental phase, meaning it could take many years for this critical plan to be brought to fruition. To be fair, it should be noted that Sprint Nextel has been testing alternate energy sources for their cellular power since 2004, already using hydrogen fuel cells at 65,000 of its sites. In addition to this, Sprint has already been making use of many of the above mentioned alternates. T-Mobile is also attempting the application of some alternatives. T-Mobile's director of national operations planning mentioned tax incentives that are given to companies from states when using alternate energy resources.
The idea of "green" wireless technology is one step closer to attaining a more livable earth. Not only is there a certain amount of radiation that is emitted from the cell phone antenna, the electricity being used to operate cell phone towers is immense. Because the electricity is generated in the current, traditional ways, it wreaks havoc on Mother Earth. These new ideas that are being generated with some cellular companies (and I'm sure all will follow suit at some point) are crucial to the necessary end result of using alternative energy wherever is humanly possible.

Cell Propagation
what is conduction/propagation?
can you please explain to me and give me an example from using these notes?
the process by which the membrane potential is changed as it travels down a cell membrane. travels by series of action potentials regenerated down the membrane
a. action potential begind at trigger point in the membrane
b. positive ions drift to next set of channels
c. depolarize that area to threshold and open voltage regulated channels to start action potential
d. when this occurs in a myelinated axon- saltatory conduction
propagation can be symbolized as "impulse conduction". Impulse Conduction- is simply the motion of action potentials at the cell membrane. In Propagation/Impulse Conduction, action potentials only depolarize a small part of the membrane. This causes that membrane and its adjacent membrane to have opposite charges. (+/-) Then electrons flow between them and is commonly referred as "mini-circuit". This causes the adjacent membrane to "potentiate" and this process is repeated over and over again. (Domino Effect- knock one down and all of them FALLS). Saltatory Conduction- a rapid travel of impulses due to the presence of myelin. Since impulses CANNOT generate THROUGH myelin, the impulse does "hopping" form node of ranvier to node of ranvier. Action Potential- a rapid change in the cell membrane's voltage. First the cell is resting, and the sodium gates are closed, but some of the K+ gates/channels are open. Then when the POSITIVE/EPSP NEUROTRANSMITTERS bind to their receptors, the sodium gates open and sodium ions diffuse INSIDE THE CELL. Then at the peak of the action potential, the sodium gates abruptly closes and the K+ gates open. As the cell is repolarizing, more K+ gates are opening and the cell finally reaches HYPERPOLARIZATION. The cell's sodium gates open briefly and the K+ gates close. Then EPSP occurs following IPSP. (Resting Membrane Potential: -70 mv, Depolarization: +30 mv.

what does this means?
"In plants, the AFPs are associated with the cell wall, other cell organelles, and the intercellular spaces. This suggests that these proteins may control the propagation of ice crystals in tissues inward from the epiphytic ice nucleators or outward from the vascular bundle."
they are connected to the cell wall??? or are near the cell wall??
they protect the cell inside and outside from the ice? is it right?
Antifreeze proteins (AFPs). "associated with" is vague. It could be inside or connected to the but just on the outside. A little googling turned up an article that says:
antifreeze proteins ... accumulate in mesophyll cell walls facing intercellular spaces
that means they are in the cell wall. They only would protect the inside by attaching to water and ice and preventing ice crystals from forming. They would probably have to be right where the ice would be forming.

has a nokia 2600 got tri band so it can work abroad?
Can a nokia 2600 work abroad in the USA?
Nokia 2600 has two version, one is USA version which is GSM 850 / 1900 - US version & outside USA version with GSM 900 / 1800 frequency. If you have bought this phone fro outside USA most likely it be later and wont work in USA. You can check your user manual maybe, since yours is tri band, it might be GSM 850/1900 compatible.
Plus this phone has to be un-locked. You can get a cheap un-locked phone & an USA SIM card online if you want from RebelFone:
