LED Emergency Lanterns: Preparing Your Home for a Power Outtage

Tuesday, August 31st, 2010

A LED emergency light is a portable light that burns cool, lasts longer than typical bulbs and uses much less energy than typical bulbs. The light produced by these lights is also significantly brighter than typical bulbs. In most cases, a LED emergency light is a flashlight, torch or lantern – all quite useful in the event that your home or office loses power or you are faced with an emergency or disaster situation.

If you have LED emergency lights there are a few things you need to know about storing them and the types of scenarios that you could consider using them for. Let’s look at ways you can get the most out of your LED emergency lights at home.

To store your emergency LED flashlight, torch or LED lantern, you should ensure that they are kept without the batteries installed in them. Batteries can leak and corrode with age and time and this leakage can completely destroy the light source and its casing. Keep two fresh sets of batteries with your LED emergency lights at all times. Make sure that the batteries are stored conveniently close to the light, either taped around it or kept inside the same box or survival kit so that you or your family will not need to hunt for them while under duress. Once every month or two, you should check to see that the batteries are working, that they haven’t corroded in their packaging and that they work with the LED emergency lights you own. If your batteries are not working, replace them with fresh ones. Mark your calendar at regular intervals to check the batteries.

Getting An Online Nursing Education

Monday, August 30th, 2010

If you are thinking of getting an online nursing education, there are several key factors that you need to take into consideration. With so many schools offering online education, there is no reason why you can not obtain the degree that is ideal for your needs. If you are ready to succeed, take some time to determine why this is a great thing for you. Getting an online nursing education is perfect for those that want to push through school and get in the field.

Here are some benefits of getting your degree online:

-Take classes when you want to from home. No need to go to the local college or to attend a college far away. Your education is right at home.

-Set your own schedule for completing your program. Often times, you can get your degree in a shorter period of time. In addition, if you need to, you can attend part time and take as long as you need to complete it.

-Get the best education from virtually any school out there. Many of the top universities are offering online education because it works. You can select to work with any of them that are offing the nursing program you are interested in.

-Work alone and benefit from personal attention. Just because you are at home learning does not mean you will not be able to work with your professor. Through web cam, telephone, email, and possibly in person conferences, you get all that you need in a personal manner.

Advanced Technical Indicators And Tools For The Modern Day Trader

Saturday, August 28th, 2010

Technical Analysis uses historical prices to identify trends and support and resistance levels. Technical indicators are derived from mathematical algorithms that use historical data to provide a current value. Most are therefore by definition lagging.

Some of the popular lagging indicators include moving averages and MACD. If you are a short term trader, these types of indicators will most likely be useless to you as their signals tend to be very late. By the time a moving average crossover occurs for example, a significant portion of the price move has already occurred.

On the other hand we have the so called “leading” indicators. Leading indicators as implied in the name are designed to lead price movements. Most of the popular ones that we know of at the moment represent some form of price momentum over a fixed look-back period. This is the number of periods used to calculate the indicator. For example, a 20-day Stochastic Oscillator would use the past 20 days of price action in its calculation and all prior price action should be ignored.

Some of the more popular leading indicators include Commodity Channel Index (CCI), Momentum, Relative Strength Index (RSI), Stochastic Oscillator and Williams %R.

One of the biggest problems short-term day traders face when using these “standard” leading indicators is that their predictive power in non-trending market conditions is largely negated. For example, when looking at the Relative Strength Index (RSI) would it be safe to buy when the indicator is oversold or sell when it is overbought? Or would a Momentum indicator tell us where price is going next? Most likely it wouldn’t.

For currency traders it gets even worse. The predictive power of these standard leading indicators is even further negated because of the persistent external news events that cause radical price moves in relation to the most recent moves. Furthermore, most of these indicators were developed for use in stock market trading decades ago. They were developed in a context where real time information didn’t exist. For currency traders, real time information is the norm.

How your brain works.

Your Brain – General Features

The Human Cortex

The most striking feature of the human brain is seen in the cortex. This is the folded, hemispherical structure which constitutes the bulk of the visible brain.

It is not present in reptiles.

The cortex is relatively recent. It is perhaps one hundred thousand years old and is the part of the brain most closely associated with our ability to form complex representations of the external world, to reason logically and to use language.

It is much more dominant in humans than in any other species.

Regions of the cortex control vision, our auditory senses, and voluntary movement and touch sensations. It is also crucial for long term memory.

Neurons and Networks

The central nervous system is composed of something like one hundred billion nerve cells or neurons.

Each nerve cell or neuron possesses a single axon along which it can pass electrical signals to other neurons. Incoming signals are carried by a neuron’s dendrites which form a tree-like structure around the neuron.

Neurons are about one micron (1 millionth meter) in diameter. The dendrites are perhaps ten times this in length while the axon varies from a millimetre up to one metre in length.
