MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

[View \| Download]	JAPANESE WATER POWERED CAR!! As per the claims it runs only on a 300W "Water Energy System (WES)" where WATER is the only FUEL. Water Car Fuelcell Internals video: http://www.youtube.com/watch?v=SuOp_9U3UeI The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, the main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction. A Japanese venture company, Genepax, has unveiled a car on that runs on water. All it requires is a litre of water. In fact, any kind of water to be exact, whether its river, rain, sea water, or even Japanese tea. Its an electric powered car that runs solely on hydrogen dioxide. "The main characteristic of this car is that no external input is needed. The car will continue to run as long as you have a bottle of water inside for you to add from time to time," said Kiyoshi Hirasawa, Chief Executive Officer of Genepax, after he proudly announced the company's invention. Once water is poured into the water tank at the back of the car, the newly invented energy generator takes out the hydrogen from the water, releases electrons and finally generates electrical power. "We highly recommend our system since it does not require you to build up an infrastructure to recharge your batteries, which is usually the case for most electric cars," said Hirasawa, who is hoping to advertise the car in time for the upcoming G8 Summit in Hokkaido, Japan. According to the company, 1 liter of water keeps the car running for about an hour with a speed of 80 kilometers or 50 miles an hour. The company has applied for a patent and is hoping to collaborate with Japanese automobile manufacturers to mass manufacture their invention in the very near future. As fuel prices continue rising and people look for greener alternatives, companies globally are trying to come up with alternatives.

Regards, Dr.Rufus The Lyrics of this video is here Targeting HIV replication The replication of HIV 1 is a multi-stage process. Each step is crucial to successful replication and is therefore a potential target of antiretroviral drugs. Step one is the infection of a suitable host-cell, such as a CD4-positive T-lymphocyte. Entry of HIV into the cell requires the presence of certain receptors on the cell surface, CD4 -- receptors and co-receptors such as CCR5 or CXCR4. These receptors interact with protein-complexes, which are embedded in the viral envelope. These complexes are composed of two glycoproteins: an extracellular gp 120 and a transmembrane gp 41 When HIV approaches the target cell gp120 binds to the CD4-receptors. This process is termed attachment. It promotes further binding to a co-receptor. Co-receptor binding results in a conformational change in gp120. This allows gp41 to unfold and insert its hydrophobic terminus into the cell membrane. Gp 41 then folds back on itself. This draws the virus towards the cell and facilitates the fusion of their membranes. The viral nucleocapsid enters the host cell and breaks open releasing two viral RNA-strands and 3 essential replication enzymes: Integrase, Protease and Reverse Transcriptase. Reverse Transcriptase begins the reverse transcription of viral RNA. It has two catalytic domains: The Ribonuclease-H active site And the polymerase active site Here single stranded viral RNA is transcribed into an RNA-DNA double helix. Ribonuclease- H breaks down the RNA. The polymerase then completes the remaining DNA-strand to form a DNA -- double helix. Now Integrase goes into action. It cleaves a dinucleotide from each 3-prime end of the DNA creating two sticky ends. Integrase then transfers the DNA into the cell nucleus and facilitates its integration into the host cell genome. The host cell genome now contains the genetic information of HIV. Activation of the cell induces transcription of proviral DNA into messenger RNA. The viral messenger RNA migrates into the cytoplasm where building blocks for a new virus are synthesised. Some of them have to be processed by the viral protease. Protease cleaves longer proteins into smaller core proteins. This step is crucial to create an infectious virus. Two viral RNA-strands and the replication enzymes then come together and core proteins assemble around them forming the capsid. This immature particle leaves the cell acquiring a new envelope of host and viral proteins. The virus matures and becomes ready to infect other cells. HIV replicates billions of times per day destroying the hosts` immune cells and eventually causing disease progression. Drugs which interfere with the key steps of viral replication can stop this fatal process. Entry into the host cell can be blocked by fusion inhibitors for example. Inhibition of reverse transcriptase by nucleoside inhibitors or by non-nucleoside Reverse Transcriptase- inhibitors is part of standard antiretroviral regimens. The action of Integrase can be blocked. Protease inhibitors are also part of standard antiretroviral therapy. Each blocked step in viral replication is a step towards better control of HIV disease.
