Java ebooks
C Programming Ebooks
In C programming, all codes are written in functions. Parameters can be passed to function by value, by reference, by name etc. C provides memory allocation such as static memory allocation, automatic memory allocation and dynamic memory allocation. C language uses C Standard Library. This library supports input, output, mathematical functions and time values, etc. C is primary used for implementing operating systems, embedded systems applications and in intermediate language.
In this posting i wish to provide free C programming language ebooks which will guide you to learn C programming language and there by you can develop low level system programs and can concentrate more on Embedded C programming.

Human Fetal Stem Cell Therapy
The Fetal Stem Cell searches out, detects and then attempts to repair any damage or deficit discovered, as well as releases growth factors, which stimulate the body’s own repair mechanisms.
These properties of the Fetal Stem Cell allow for unique treatment intervention in a multiplicity of diseases for a large group of patients who up until now have not had any means for recovery.
Nanotechnology
An early promoter of the industrial applications of nanotechnology, Albert Franks, defined it as 'that area of science and technology where dimensions and tolerances in the range of 0.1nm to 100 nm play a critical role'. It encompasses precision engineering as well as electronics; electromechanical systems (eg 'lab-on-a-chip' devices) as well as mainstream biomedical applications in areas as diverse as gene therapy, drug delivery and novel drug discovery techniques.
Because nanotechnology has opened up new worlds of possibility, it has spawned a proliferation of new terminology - a kind of nanospeak to the uninitiated. For example, the two fundamentally different approaches to nanotechnology are graphically termed 'top down' and 'bottom up'. 'Top-down' refers to making nanoscale structures by machining and etching techniques, whereas 'bottom-up', or molecular nanotechnology, applies to building organic and inorganic structures atom-by-atom, or molecule-by-molecule. Top-down or bottom-up is a measure of the level of advancement of nanotechnology. Nanotechnology, as applied today, is still in the main at what may be considered the more primitive 'top-down' stage.
A breakthrough that may herald the beginning of the 'bottom-up' stage of nanotechnology has been the discovery of spinning molecular structures. These may open the door to realising the holy grail of power generation and controllable motion at the molecular level, with huge applications for medicine and information technology.
Another feature of nanotechnology is that it is the one area of research and development that is truly multidisciplinary. Research at the nanoscale is unified by the need to share knowledge on tools and techniques, as well as information on the physics affecting atomic and molecular interactions in this new realm. Materials scientists, mechanical and electronic engineers and medical researchers are now forming teams with biologists, physicists and chemists.
ETHICAL AND SOCIAL CONSIDERATIONS*
Over thirty years ago 20th Century Fox took the moviegoing public (and Raquel Welch) on a "Fantastic Voyage." In this cinematic barn-stormer, a diplomat lay near death from a blood clot, until, through miraculous technologies, scientists shrank a 30-foot-long clot-busting metal ship to the size of a pin's head
Audiences shuddered and gasped as the miniature ship sailed through the bloodstream, encountering white blood cells that seemed as large as the Brobdingagian giants confronted by Gulliver on his travels. The ship's crew narrowly avoided destruction and its heroes were restored to normal size. It was a fantastic first step toward human dreams of shrinking medicine to microscopic size. Today at the cinema we are entertained by even more dramatic stories of kids shrunk to the size of ants and microscopic machines sent to infect the world. But is it just fiction?
In 2000, the barrier between man and machine is as thin as a strand from the double helix. As computer equipment, surgical tools and communications pipelines shrink ever smaller, the next step in engineering is to merge biological and mechanical molecules and compounds into really, really small machines. This will happen in many different ways, and it raises many new issues.
First, we are beginning to see life forms reduced to molecular codes. This means that in our lifetime, viruses and components of our own DNA are going to become a lot more portable. Today, the last samples of smallpox virus are locked away in a vault in Atlanta at the Centers for Disease Control and Prevention. Tomorrow, getting smallpox may be as simple as forwarding an e-mail attachment with the smallpox DNA code to a $5,000 DNA synthesizer. The portability of DNA also means that where you once thought of your DNA as a part of your body, tomorrow the DNA from any of your cells might be used to make a cloned embryo or to make a big sack of cloned tissue for transplantation.
Is it ethical to move life around this way, playing mix-and-match with bits from different animals and species? Should we create entirely new kinds of life from the molecule up? Would it be wrong to build a bacterial life form that depended on a machine for survival, such as battery-acid-powered carpet-stain-removal bacteria? Or is that no more problematic than executing billions of little yeast molecules to make a barrel of beer or a loaf of bread?
Second, enhanced DNA and computers are more and more becoming parts of our bodies. Millions watch as Captain Picard and the crew of the Starship Enterprise battle a genetically engineered race called The Borg, who are the ugliest possible combination of DNA with computers (with the exception, of course, of new Borg sex symbol, Seven of Nine).
The Borg aren't real, but human-machine integration isn't just fiction anymore. Teams at MIT, Xerox and elsewhere are racing to connect you very closely to your cell phone and television. Within a few years, pacemakers and other medical devices will begin corresponding electronically with hospitals, physicians and even insurance companies about the patients whom they "inhabit." Many aspects of our behavior will be monitored more closely, and we may even get insurance discounts if we agree to "show" what healthy people we are!
Ethical issues in merging with computers go beyond the "weird" factor into a whole new kind of problem: what happens if human beings are made from non-human parts? Is a baby made from cloned DNA, gestated in a bubble and connected to a cellular phone still human? The answer matters because it is no longer obvious what it means to call something or someone "normal" or a "person," even in the world of medicine. That means it is getting harder and harder to figure out which advances in medicine are worth public research money and which ought to be mothballed.
Most interestingly, we are approaching the world of Fantastic Voyage. Experts in this new field of nanotechnology promise a world in which very small machines literally circulate within us, pursuing bad bacteria and viruses and dissolving cholesterol and lipids. It sounds great, if a little bit spooky, but it is still a long way away.
So should we spend taxpayers money on clot-breaking machines to extend the average life span, or work to build other artificial devices much smaller - and more effective - than the artificial heart of the 1970s? It is a difficult decision but one that only our generation can make.
Saving Social Security takes on a whole new meaning in a world that works hard to keep people alive well into their 100s, but connected to dozens of expensive little machines. As we prioritize about hunger, our status as a global power and the future of medicine, many of the most troubling decisions will be very, very small.
