    RAINMAKING
    August 18, 1891 - Midland, Texas. USA

    The first rainmaking experiments in the U.S. were conducted near Midland, Texas, paid for by a grant from the U.S. government. Patent attorney Gen. Robert Dyrenforth set off explosive balloons and artillery to try to make rainclouds develop. At a time of extreme drought, any effort with a hope of success may have been thought worthwhile to try, but there were no results. The method chosen was to test a theory that rainstorms seemed often to occur where major battles had taken place during the Civil War, and they may have been because of the effect of smoke, dust and disturbances in the air from artillery.

    SEVENTY-TWO NOBEL PRIZE-WINNING SCIENTISTS FILED
    August 18, 1986 - Louisiana, USA

    seventy-two Nobel Prize-winning scientists filed a legal brief with the U.S. Supreme Court challenging as unconstitutional a Louisiana law requiring schools that teach evolution to also teach reation-science. A news release described the scientists as the largest group of Nobel laureates ever to support a single statement on any subject. At a news conference in Washington D.C. the same day, they warned that the Louisiana law threatened scientific education by disparaging proven scientific facts to promote fundamentalist Christian beliefs. Dr. Murray Gell-Mann (1969 Nobel Prize in Physics), led the effort. A Federal District Court had struck down the Louisiana law in Jan 1985, as promotion of religious belief. A U.S. Court of Appeals agreed. The Supreme Court ruled against the law on 19 Jun 1987.

    about Eyesight Myth and Fact

    Myth: Staring at a computer screen all day is harmful to the eyes. Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them.

ARTICLE INFORMATION :

The article concentrated upon technological advances that favourably influenced the efficacy of office work, and features a PDF splitting software package as one of the solutions to document handling.

ARTICLE CONTENT :

We live in the time of fast development. Because of the recent technical advances in the IT sphere, office work is no longer the same as it used to be several years ago, with piles of paper documents here and there around the office. Documents, undeniably, adversely impacted on the efficacy of a firm and it took office staff a good deal of time and effort to manage them. At present the days of paper-cluttered offices are gone. There are no more 'in' and 'out' boxes piled up with paper files. Everything is now computerised and kept in the form of a database.

No wonder that advanced software programmes are introduced daily to optimise the office work. These up-to-date programmes do not only do work much quicker, but also much easier. Most files are stored in the PDF format, since it has got plenty of benefits over others. PDF files are smaller and can be protected with encryption and password security tools. The PDF application is a compatible format. As a consequence, a user can share and get data from colleagues efficiently.

PDF files can range from a single-page file to more composite files, such as brochures, information sheets, white papers and technical instructions, some containing hundreds of pages, which makes them hard to handle. Now and then, you may wish to print or e-mail a couple of pages from a PDF document or to extract several pages into a new PDF papers leaving the master file intact. A solution is to use a PDF splitter software package. This kind of software is user-friendly. It allows you to select your master (or input) PDF document and apply a splitting pattern to obtain the output document(s).

Some advanced software packages include a customised splitting option, similar to Word printing pattern. Here is an example: 1,2,3; 1-5,3; 4-5. This will result in three output files. The first one will include pages number 1, 2 and 3. The second PDF file will have pages one to five and page three. The third one will include only pages four and five. It takes a few mouse clicks to extract pages from PDF documents and does not need expertise. A step-by-step direction is provided by manufacturers.
