X-ray machine from 1896 compared to modern version
The original system was developed by high school director H J Hoffmans and local hospital director Lambertus Theodorus van Kleef from Maastricht in the Netherlands.
Following a publication by X-ray discoverer Wilhelm Roentgen just weeks before, the pair built their device from parts found at the high school and used it for anatomical imaging experiments.
The team carefully recreated the experimental conditions that the machine's inventors would have used. Given that a high radiation dose might be required to carry out the tests, the team obtained a hand from a cadaver as their imaging subject - rather than the "young lady's hand" listed in Hoffmans and van Kleef's notes.
Within a year of the rays' discovery they had become both a medical and theatrical showpiece, and the first indications arose that extensive exposure could be harmful. As a result, part of the race in X-ray science has been produce better images with less radiation exposure.The team accordingly found that using a modern detector, a radiation dose 10 times higher was required from the antiquated system when compared to a modern one.
Using a photographic plate and the same imaging conditions Hoffmans and van Kleef used, a dose 1,500 times higher was required.What is more, the X-rays exited the machine over a broad area, leading to blurry images.But putting the equipment to the test was evidently reward enough for the authors"Our experience with this machine, which had a buzzing interruptor, crackling lightning within a spark gap, and a greenish light flashing in a tube, which spread the smell of ozone and which revealed internal structures in the human body was, even today, little less than magical," they wrote.
The machine ended up in a warehouse in Maastricht and was unearthed last year for a history programme on television.
Then Gerrit Kemerink of Maastricht University Medical Center decided to put the equipment to the test against a modern system.
"To my knowledge, nobody had ever done systematic measurements on this equipment, since by the time one had the tools, these systems had been replaced by more sophisticated ones," said Dr Kemerink.

Public Awareness over Environment
The public need awareness over environment because everyone has to know
about the treats to our environment. if every one knows about this, so
they will take some steps or advice youngsters not to do anything that harms
our environment.
environment is nothing but the place where we survive. everyone is a public.
so, they may find new methods to make our products without destroying plants
and other living beings.
one can save his petrol and oil and any other non - renewable resource, that
will be very useful for the future generations. we should not deny our future from
the great gifts of nature.

Environment awareness : Afridi
ISLAMABAD: Environment Minister Hameedullah Jan Afridi on Monday said that his ministry’s focus was on creation of public awareness of environment protection and ways to offset negative effects of climate change.
Talking to Swedish Ambassador Ulrika Sundberg at the ministry, Afridi said several initiatives had been taken to involve students in public awareness campaigns about environmental issues.
He said green clubs were being formed in schools with an aim to conserve environment.
The minister said efforts were on to increase the country’s forest cover. “We carry out tree plantation campaigns in the country’s various parts on a regular basis with the help of public and private organisations, students and general public,” he said.
He said he was hopeful that such activities would lead to better public awareness of environmental issues and thus, better protection of environment.
Afridi appreciated the role of media in highlighting issues and challenges facing environment. He called for better use of modern technology to effectively deal with environmental challenges faced by the country.
He declared global warming and climate change as a threat to environment. “We are among those countries, which face adverse effects of environmental changes. However, we are alive to the challenge and trying to cope with it in an effective manner,” he said.

A Healthy Life
I've never been an athlete. I've never been much interested in sports, ever since I stopped playing touch-football with the boys, when I hit puberty. I've tried tennis. I hit the ball too high, too long, and way over into left field. I've tried softball. Thank goodness that ball is "soft" and big, because it felt just awful when it hit me in the eye. I tried running, but I couldn't get anyone to chase me.
I tried swimming, but even though I float like a cork, and have had numerous lessons, I can't seem to get over the idea, that I'm really going to drown. Finally, I settled on walking, and for a number of years, I walked 3 to 5 miles a day. I realize that there is an Olympic sport referred to as "walking," but when I tried that, all I succeeded in doing was throwing my hip out.
I'm definitely NOT an athlete, but I make do, especially in my "mid-life" years. Which brings a question to my mind. When did I hit mid-life? I remember when I hit thirty. I had to visit a grief counselor, because I knew my life was over. I remember forty. I had to see a grief counselor, the day after my first child graduated from high-school and moved out of the house, because I knew my life was over. I remember forty-four. For some reason I thought my life was over. Then I hit fifty, and I was all excited, because I was able to join an organization called AARP. My husband was, especially, excited because he is younger than I, and he got to join, too!
Fifty became the magic age. I knew that as long as I was in good health, in this day and age, I probably had a good fifty years ahead of me. Then came the asthma. O.K., I had that much earlier, but it only became life threatening after fifty. Then came the firbromyalgia. O.K., I had THAT earlier, but it's not life threatening. Then came the arthritis, and, more recently, at fifty-five, came the diabetes. Somewhere, along in there, I became very interested in pharmaceuticals, and, finally, one day, I became free.
I began by noticing the sunsets, and I had the time to stop and really wonder, at the beauty and the magnitude of it all. Then I moved onto the sunrises, and I quickly found out that if I wasted the early morning, I missed the loveliest part of the day. Then I began to notice how grateful I was to be able to witness the changing of the seasons. The first whisper of spring; the rustling of the leaves beneath my feet, in the fall; that first breathless covering of a winter's snow; and in the summer, all the flowers, and the buzzing of a bumblebee.
When illness would hit me, I found that I, actually, enjoyed the solitude. A time to reflect, gather my thoughts, and pray, at leisure. I found that I was "experiencing" this mid-life season, and I was no longer missing every moment, shackled to the chains of worry, and what "might" be. I found that worrying about tomorrow, only served to make me overlook the blessings of today.
It's not always easy. A few loads of laundry, and a pile of dishes can take an entire day; but then I don't push myself a lot. So, I forget to make the bed, as I watch the rosy glow of dawn meet the rising sun. I have time to walk our little, wooded acre with my little dachshund straining at the leash. I get to read the "signs," with my Happy Dog, sniff the air, and gaze out at nowhere, studying the sky, with the same intensity that my little dog studies the ground.
I get to meet the day, every day. I get to say "good-night," to the sunsets. I've studied a lot of sunsets, in the last five years, and I've never seen two that were alike. I get to know my Creator as I never have before, and I've gotten to make MY mind up, about the mysteries of life; and I have grown certain, that all this was no accident.
I feed the birds, and I take great delight in their multicolored hues, especially in the spring. I drag a chair to stand on, so that I can fill the feeders to the brim, myself. I say a little prayer, as I wobble, a little cock-eyed on the chair, and I laugh, at myself, and all the pretensions of my younger life. I take great delight in my life. I thank God for all the precious little things of every day. Friends. Family. Neighbors. And health. A health of the soul. For I have come to understand what real health is, and when you have REAL health, then you truly have everything.

The Novels of Jane Austen on Film
Unsurprisingly, Pride and Prejudice has been the Austen novel most often adapted for film. The first big screen interpretation came as early as 1940, when Aldous Huxley wrote the screenplay for a version which starred Greer Garson as Elizabeth Bennet, with Lawrence Olivier as Mr Darcy. The film won an Oscar for best Art Direction. More recently Keira Knightley and Matthew Macfadyen stepped into the shoes of the feisty couple in 2005, Knightley was Oscar nominated for her role, and the film was generally well received, although it arguably failed to eclipse the 1995 television adaptation which shot Colin Firth to fame.

Inventors of the Modern Computer
The first Apple was just a culmination of my whole life." - Steve Wozniak, Co-Founder Apple Computers
Following the introduction of the Altair, a boom in personal computers occurred, and luckily for the consumer, the next round of home computers were considered useful and a joy to use.
In 1975, Steve Wozniak was working for Hewlett Packard (calculator manufacturers) by day and playing computer hobbyist by night, tinkering with the early computer kits like the Altair. "All the little computer kits that were being touted to hobbyists in 1975 were square or rectangular boxes with non understandable switches on them..." claimed Wozniak. Wozniak realized that the prices of some computer parts (e.g. microprocessors and memory chips) had gotten so low that he could buy them with maybe a month's salary. Wozniak decided that, with some help from fellow hobbyist Steve Jobs, they could build their own computer.
On April Fool's Day, 1976, Steve Wozniak and Steve Jobs released the Apple I computer and started Apple Computers. The Apple I was the first single circuit board computer. It came with a video interface, 8k of RAM and a keyboard. The system incorporated some economical components, including the 6502 processor (only $25 dollars - designed by Rockwell and produced by MOS Technologies) and dynamic RAM.
