    THE FIRST IRON LUNG
    July 29, 1927 - United States

    (Electric Respirator) was installed at Bellevue hospital in New York for the post war polio epidemic. The first iron lung was developed at Harvard University by Phillip Drinker and Louis Agassiz Shaw built with two vacuum cleaners. The iron lung is a negative pressure machine which surrounds the patient's body except for the head, and alternates a negative atmospheric pressure with the ambient one, resulting in rhythmic expansion of the chest cage (and thus inhalation) in response to the negative extra thoracic pressure. During periods of ambient extrathoracic pressure, the lungs deflate. This type of machine is rarely used today.

    AMERICA'S FIRST ASPHALT PAVEMENT
    July 29, 1870

    Was laid in Newark, N.J. Previously, coal tar was used for many pavements laid in the 1860s. The first recorded asphalt pavement in the U.S. was a sand mix placed in front of the City Hall in Newark, N.J., in 1870. Edmund J. DeSmedt, a Belgian chemist (who became the inspector of asphalt and cements for the District of Columbia) held a U.S. patent for this asphalt paving method, granted on 31 May 1867. In that century most roads, even in cities, were wide dirt pathways, severely affected by weather. Smooth surfaced asphalt roads originally were for the benefit of bicyclists. By 1904, only 141 miles were surfaced, but commonplace by 1916. Natural asphalt deposits were originally used, but almost all of the asphalt used commercially is now made from petroleum.

  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."

Directory submission is a technique that makes use of different web directories for submitting your web site. By making these submission you can always effectively increase the ranking of your website. In case the directory is already receiving too much of web traffic then there are complete changes that all that traffic can be directed towards your website. You can always make use of manual directory submission service and automated directory submission services for submitting your website to these directories. Both of these methods are in fact having their own set of advantages and disadvantages but the choice is always yours.

Most webmasters always prefer making use of manual submissions as this is generally considered very much effective. When doing manually you may have to visit each of the web directories individually and then do the submissions. This type of process is generally considered as more time consuming but is considered as very much effective and result oriented. One of the main advantages of making use of manual directory submission service is that you always have a better chance of lowering falling prey to spam that are always at higher risk when doing automatic submission. The approval percentage in case of manual submission is also very much high as you can always select the right category to do your submission.

There are a number of web directories that only allow manual web directory submission as they certainly are very much reluctant to the automated type of services. So the moment they detect any automated directory submission service they simply disapprove all the details related to that URL from their directory database. So after your URL is eliminated then you may never be able to do your submissions next time. When you choose to submit to web directories manually then you certainly have a choice where you can make your selection of directories for submission. Since thousands of web directories are available so if you choose to submit in each one of them, then the process can be time consuming.

One of the best alternatives is to try and outsource the job to a professional SEO company so you can save your time and money. Even before selecting any such company it is important that you read a few reviews related to them online so you are sure that you have selected one of the best companies for completing the job effectively. The general rule when doing directory submission is to try and submit to a few directories in a single day so you can get the desired results. In case you are looking for much better results then selecting a delayed submission service is also one good option. Such manual directory submission services complete the job in different steps over a period of time to make the submission more effective. So there are chances that they might even choose to complete nearly 1000 submissions in a period of one month. They certainly might also make use of separate titles for each submission to get better results.
