How Fusion Reactions Work

How Fusion Reactions Work

In nuclear physics and nuclear chemistrynuclear fusion is the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energyIron and nickel nuclei have the largest binding energies per nucleon of all nuclei. The fusion of two nuclei with lower mass than iron generally releases energy while the fusion of nuclei heavier than iron absorbs energy; vice-versa for the reverse process, nuclear fission.

Nuclear fusion occurs naturally in stars. Artificial fusion in human enterprises has also been achieved, although not yet completely controlled. Building upon the nuclear transmutation experiments of Ernest Rutherford done a few years earlier, fusion of light nuclei (hydrogen isotopes) was first observed by Mark Oliphant in 1932, and the steps of the main cycle of nuclear fusion in stars were subsequently worked out by Hans Bethe throughout the remainder of that decade. Research into fusion for military purposes began in the early 1940s, as part of the Manhattan Project, but was not successful until 1952. Research into controlled fusion for civilian purposes began in the 1950s, and continues to this day. (from Wikipedia )

Intel Launches Core i7 Processor

Why Intel's Core i7 Processor Is a Beautiful Monster

Why Intel's Core i7 Processor Is a Beautiful Monster

"Last week, you probably noticed new computers from Dell, Gateway and others using a brand new, bizarre-sounding chip from Intel: the Core i7. You might have even seen some benchmarks and features showing that this is a real beast of processor. Well, we're pretty excited about the Core i7, so here's a quick guide to why it's so awesome:

Hokay, so the way Intel develops chips is on what it calls the "tick-tock cycle". The "tick" is the improvement of its current microarchitecture, mainly shrinking it down to make it more energy efficient, along with other tweaks. As you now can guess, the "tock" indicates the launch of a totally new microarchitecture.

Penryn, for instance, was the tick to the Core 2's tock, shrinking it down from a 65-nanometer process to 45nm. Core i7 is a tock, using a completely new microarchitecture codenamed Nehalem. Core i7 Nehalem is actually a dramatic step forward, remedying several lingering Intel architecture deficiencies that AMD actually had them beat on years ago. So, here are four things that specifically make the new chip awesome:

Bye Bye Front-Side Bus

The ancient front-side bus setup has long been a drag on Intel's chips, and they're finally ditching it. The FSB essentially carried data between the CPU and memory controller hub (which is also out the window, more on that in a sec), but that didn't work so well when you started talking buckets of cores. In its place is a new tech called QuickPath Interconnect that'll make the old bottlenecks history and running tons of cores even better. QPI uses direct point-to-point connections that have a bandwidth of about 25GB/s, way faster than what FSB could offer. The downside is that it requires a new QPI-friendly motherboard. This concept is kind of cribbed from AMD, whose HyperTransport has been doing something similar for a longass time.

Integrated Memory Controller and Triple-Channel Memory
You might notice a pattern that a lot of Nehalem's performance boosts have to do with better access to memory and fatter bandwidth. Yet another tech that AMD held over Intel's head for years is an integrated memory controller, which Core i7 finally uses. Basically this just means that the memory controller is on the same die as the CPU, cutting down memory latency. Before, with Intel chips, communication had to take place across the front-side bus, making stuff slooooow. The last memory bonus is that Core i7 supports triple-channel memory. Right now, you're probably on a computer using dual-channel memory (in English, I mean that it uses RAM sticks in sets of two). Core i7 will make three sticks of RAM the new standard—so keep an eye out for plenty of 6GB and 12GB systems running around.

The Return of Hyper-Threading
Intel abandoned Hyper-Threading after the Pentium 4, but it's back in Core i7 (and Atom, but really, psh). Basically, it's a parallel-processing tech that runs multiple threads simultaneously. In English, it divvies up tasks so they can be crunched by a processor simultaneously, instead of one after the other. It short, it makes video encoding and other parallel-friendly processes run faster. We're interested to see what kind of gains this will produce in tandem with programs coded to take advantage of threading, not to mention the next great operating systems, Snow Leopard and Windows 7, which will supposedly make better use of multiple cores and parallel processing than current OSes.

Built-In Power Management and Overclocking
Core i7 is pretty much a beast already, but whereas Intel used to say that overclocking was bad for your processor, now with the Core i7, it's built right in. The Core i7 is really aggressive with power management, more so than Core 2, so it'll sip juice when it's not busy, and then crank the power when it needs it. In the BIOS now, you can set it to overclock the CPU in certain situations, and customize that by thermal ratings so it won't overheat.

So yeah, Core i7 gets our engines running, and we're not even chip nerds. (Honest!) Sadly though, right now there are just a few Core i7 chips available, and they're all for desktops. There's not much of a downside for portables—save for the need for new motherboards and the DDR3 RAM already used by premium laptops—but before you see it in a Dell XPS notebook or MacBook Pro, you're going to see it in a lot of desktop gaming and graphics-intensive systems. Laptops probably won't appear until way into next year, but we think they'll be well worth the wait"[1].

What is an Artificial heart

An artificial heart is a prosthetic device that is implanted into the body to replace the biological heart. It is distinct from a cardiopulmonary bypass machine (CPB), which is an external device used to provide the functions of both the heart and the lungs. The CPB oxygenates the blood, and therefore does not need to be connected to both blood circuits. Also, a CPB is suitable only for a few hours use, while artificial hearts have been used for periods longer than a year (as of 2007).

Doctor designs artificial heart

A cardiac surgeon and a french biomedical company are creating an artificial heart which could save the lives of thousands.Cardiac surgeon Alain Carpentier is working alongside Carmat SA to create the artificial implantable organ. The biomedical company is being backed by aerospace giant EADS.Preliminary lab tests on the artificial heart have produced promising results.

What is Melamine

What is Melamine

"Melamine (pronounced /ˈmɛ lə miːn/ melamine) is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals who have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants.

Melamine combines with cyanuric acid to form melamine cyanurate, which has been implicated in the Chinese protein export contaminations"[1].

what is Cancer


Read more about Cancer - http://www.cancer.com/cancer/

"Cancer (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not. The branch of medicine concerned with the study, diagnosis, treatment, and prevention of cancer is oncology.

Cancer may affect people at all ages, even fetuses, but the risk for most varieties increases with age.[1] Cancer causes about 13% of all deaths.[2] According to the American Cancer Society, 7.6 million people died from cancer in the world during 2007.[3] Cancers can affect all animals.

Nearly all cancers are caused by abnormalities in the genetic material of the transformed cells. These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents. Other cancer-promoting genetic abnormalities may be randomly acquired through errors in DNA replication, or are inherited, and thus present in all cells from birth. The heritability of cancers are usually affected by complex interactions between carcinogens and the host's genome. New aspects of the genetics of cancer pathogenesis, such as DNA methylation, and microRNAs are increasingly recognized as important.

Genetic abnormalities found in cancer typically affect two general classes of genes. Cancer-promoting oncogenes are typically activated in cancer cells, giving those cells new properties, such as hyperactive growth and division, protection against programmed cell death, loss of respect for normal tissue boundaries, and the ability to become established in diverse tissue environments. Tumor suppressor genes are then inactivated in cancer cells, resulting in the loss of normal functions in those cells, such as accurate DNA replication, control over the cell cycle, orientation and adhesion within tissues, and interaction with protective cells of the immune system.

Diagnosis usually requires the histologic examination of a tissue biopsy specimen by a pathologist, although the initial indication of malignancy can be symptoms or radiographic imaging abnormalities. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for different varieties of cancer. There has been significant progress in the development of targeted therapy drugs that act specifically on detectable molecular abnormalities in certain tumors, and which minimize damage to normal cells. The prognosis of cancer patients is most influenced by the type of cancer, as well as the stage, or extent of the disease. In addition, histologic grading and the presence of specific molecular markers can also be useful in establishing prognosis, as well as in determining individual treatments"[4].

Types Of Mesothelioma

Pleural Mesothelioma
"Pleural mesothelioma is a type of cancer that affects the pleural sac that surrounds the lungs, and is caused by exposure to asbestos. Pleural mesothelioma is the most common form of mesothelioma with estimated 75% of all mesothelioma cases being of this form.

Peritoneal Mesothelioma
Peritoneal mesothelioma is a cancer that affects the thin cell membrane called the peritoneum. This collection of cells surrounds the gastrointestinal tract and provides lubrication for the stomach and intestines to move so that they may function properly. These organs must be able to move properly in order to properly digest and process food, and a failure in the peritoneum can result in severe and debilitating consequences. Unfortunately, the symptoms of peritoneal mesothelioma can be so subtle that it can be confused with other, less dangerous diseases, and this aspect of the disease significantly contributes to its already staggering mortality rate.

Pericardial Mesothelioma
Pericardial mesothelioma is the rarest type of the three main malignant forms of the disease. The heart, as with any organ that requires constant movement to work properly, requires constant lubrication. Lubrication comes in the form of a thin layer of mucous, and in normal systems the heart beats on as normal'[1].

Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body's internal organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.

Mesothelioma Symptoms and Diagnosis


What are the symptoms of mesothelioma?

    "Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.

    These symptoms may be caused by mesothelioma or by other, less serious conditions. It is important to see a doctor about any of these symptoms. Only a doctor can make a diagnosis"[1].

What is the mesothelium?

    "The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

    The mesothelium has different names, depending on its location in the body. The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity. The pericardium covers and protects the heart. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women"[1].
