Determined to leverage the domestic production of diesel fuel, Petrobras is investing in technology to transform its future refineries into units that are fully prepared not only to inject more diesel into the market, but also to produce a better quality fuel. Of the four new Petrobras projects on the drawing boards, the Northeast Refinery and the Premium Refineries have something in common — the search for solutions to produce increasingly less gasoline and more diesel fuel. For its part, the Comperj petrochemical complex will innovate by using an FCC unit that not only produces gasoline, but also by-products such as ethane and propane directly from heavy oil.

Petrobras is investing heavily in refining, based upon the forecast for a growth in consumption of domestic oil products of 3% per year through 2013. However, data released by the National Petroleum Agency (ANP) demonstrates that the prospects could be even better for diesel, whose consumption increased 7.7% between 2007 and 2008. With a 41% increase in ethanol consumption over the 2007-2008 period and the growing fleet of flex fuel vehicles, the only oil product that threatens fuel supplies in the country is diesel, which is imported today and used massively for highway cargo transportation.

“Diesel is the oil product that is growing the fastest. It is not for nothing that the Premium refineries, planned to operate in 2013, are being optimized to produce diesel,” stated Petrobras’ director of Supplies, Paulo Roberto Costa.

Among the major investments foreseen by the company, refining is where 73% of the total earmarked for the Supplies area will be concentrated. By increasing production projections for diesel in its 2009-2013 Strategic Plan, Petrobras is trying to reduce the impact of the product on Brazil’s trade balance, under the fuel import line item. In this context, technology is a fundamental tool.

“The entire world is seeking a way to produce more and better quality diesel fuel. Anyone who is able to patent this first will have a competitive advantage,” said Eduardo Guerra, general manager of Basic Engineering and Refining at Cenpes, the Petrobras Technology Center.

RNEST

One of Petrobras’ main investments is the so-called Northeast Refinery (the Abreu e Lima Refinery or RNEST). Scheduled to come on stream in 2011, the unit in a first stage would produce 200,000 bpd. However, improvements to the projects would increase the load by another 30,000 bpd, boosting capacity up to 230,000 bpd.

At RNEST, the star of the show is the Retarded Coking Unit (RAT). Normally, the refineries that produce gasoline make use of atmospheric distillation units, accompanied by vacuum distillation units and an FCC (Catalytic Cracking Unit). Because RNEST’s focus is diesel, the scheme does not require the FCCs, which make gasoline a priority. Atmospheric distillation inserts a direct load into a coke unit that has been designed by the Cenpes. The coke unit will process the atmospheric residues directly, without treatment.

“The reverse of the vacuum load process, the coke unit directly processes the atmospheric distillation load. After the coke, the load goes directly f

It’s hard to think of any other device that’s enjoyed the level of exposure and hype that Apple found in the launch of the first iPhone. Who could forget it? Everyone got to be a gadget nerd for a day; even those completely disinterested in technology seemed to come down with iPhone fever. But the original device was still far from perfect: its limited capabilities (especially in the 3G department), high price of entry, and the small number of countries in which it was available kept many potential buyers sidelined. Until now — or so Apple hopes.

The wireless industry is a notoriously tough nut to crack, and it’s become pretty clear that the first iPhone wasn’t about total domination so much as priming the market and making a good first impression with some very dissatisfied cellphone users. With the iPhone 3G, though, Apple’s playing for keeps. Not only is this iPhone’s Exchange enterprise support aiming straight for the heart of the business market, but the long-awaited 3rd party application support and App Store means it’s no longer just a device, but a viable computing platform. And its 3G network compatibility finally makes the iPhone welcome the world over, especially after Cupertino decided to ditch its non-traditional carrier partnerships in favor of dropping the handset price dramatically. $200? We’re still a little stunned.

So now that Apple finally stands poised for an all out war on cellphone-makers everywhere, will the iPhone 3G stand up to the competition — and higher expectations than ever? Read on for our full review.

Microsoft released a record number of 13 bulletins for 34 vulnerabilities on Patch Tuesday–and the first critical update for Windows 7–as well as fixes for zero-day flaws involving Server Message Block (SMB) and Internet Information Services (IIS).

The most severe of the three SMB flaws, which were first reported last month, could allow an attacker to take control of a computer remotely by sending a specially crafted SMB packet to a computer running the Server service. Exploit code for one of the SMB holes has been posted to the Web, Microsoft said.

Windows 7 is affected by two critical patches intended to mend vulnerabilities that could allow remote code execution if a malicious Web page were viewed, one part of a cumulative security update for Internet Explorer and the other in .Net Framework and Silverlight.

The official release date for Windows 7 is October 22, but the new operating system has been available to some large businesses with volume licenses since the summer. The code was finalized in July.

Other critical patches in the security bulletin for October fix a vulnerability in Windows Media Runtime that could be exploited if a user opened a malicious media file or received malicious streaming content from a Web site or application, and if a specially crafted ASF (Advanced Systems Format) file is played using Windows Media Player 6.4.

Among the critical updates: a cumulative security update of ActiveX Kill Bits that is being exploited and that affects ActiveX controls compiled using Active Template Library (ATL); and another patch resolving several vulnerabilities in ATL ActiveX Controls that could allow remote code execution if a user loaded a malicious component or control. ActiveX and ATLs were the subject of an emergency patch Microsoft released in July.

The final critical bulletin fixes a hole in Windows GDI+ (Graphics Device Interface) that could allow an attacker to take control of a computer if the user viewed a malicious image file using affected software or browsed a malicious Web page.

“Microsoft has repeatedly had to fix problems related to the Graphics Device Interface in Windows, and vulnerabilities in the component have been exploited broadly in the past. We can expect that security researchers will be looking to reverse-engineer today’s patches, which may very well lead to exploits being created,” said Dave Marcus, director of security research and communications at McAfee Labs.

Nine of the vulnerabilities were previously disclosed, which meant that attackers had time to come up with so-called “zero-day” exploits before the patches were available, Marcus noted.

The most alarming vulnerability in the mix is the SMB flaw, which was introduced by the patch for a different vulnerability, according to Josh Phillips, virus researcher at Kaspersky Lab.

Andrew Storms, director of security operations at nCircle, said the bug that is likely to have the biggest impact will be the critical one that affects Windows Media Runtime and involves a speech codec bug that has limited exploits in the wild. “This is a typical file-parsing issue and similar to vulnerabilities that have allowed attackers to create drive-by attacks that infect unsuspecting video viewers,” he said.

Meanwhile, the critical SMB vulnerability is relatively difficult to exploit given default firewall conditions, but the IIS bugs are easy to exploit, Storms added.

“The sheer volume of the bulletins and patches is extreme,” said Jason Miller, senior data team leader for Shavlik Technologies. “This is really going to affect administrators. It’s going to be very challenging because of the time and research that’s going to be needed” to patch systems.

Also released were five bulletins rated “important” to fix vulnerabilities in IIS, for which exploit code has been publicly released and for which there have been limited attacks, along with Windows CryptoAPI, Windows Indexing Service, Windows Kernel, and Local Security Authority Subsystem Service.

The update for Windows CryptoAPI relates to flaws in the way domain names are verified on the Internet, which could allow attackers to impersonate a site and steal information from unsuspecting Web surfers. The holes were revealed by researchers Dan Kaminsky and Moxie Marlinspike at Defcon in August.

Affected software includes Windows 7; Windows 2000; Windows XP; Windows Vista; Server 2003 and 2008; Office XP, 2003, and 2007; Microsoft Office System; SQL Server 2000 and 2005; Silverlight; Visual Studio .Net 2003; Visual Studio 2005 and 2008; Visual FoxPro 8.0 and 9.0; Microsoft Report Viewer 2005 and 2008; Forefront Client Security 1.0; and Office software including Visio, Project, Word Viewer, and Works.

The installation also removes the Win/FakeScanti Trojan, which displays fake malware warnings and then asks computer users to pay for fake antivirus software.

The invention of the Big Bang copy brand saw the arrival of two major models of the brand namely; the diver timepiece duplicate and the replica Hublot Classic. These are wonderful models of the replica Hublot brand that have continued to come out in various versions. The fake Hublot particularly has wonderful features that attract many young men and women of today.
The Uniqueness
The Uniqueness of the Replica Hublot Classic is seen mainly in three areas: its efficiency, affordability and durability.
The Efficiency
Replica Hublot Classic is known for its accuracy in time keeping. This is mainly because of the quality dials and other sub-dials used in its production. The Replica Hublot also has the self inbuilt rotor and precise quartz movement that propel it to proper actions.
Replica Hublot Classic also comes with wonderful self winding knob which is used in the adjustment of the watch for better time regulation.
The affordability
Replica Hublot Classic is known for its cheapness in the entire Swiss Replica world. The main Hublot Classic goes for $5000 and above while the Replica Hublot Classis sells as low as $280 and below. This cheapness attracts many customers to the brand. The low in price does not make the Replica Hublot Classic to be inferior or bad. Rather the Replica Hublot Classic remains very effective in time keeping.
Durability
The Replica Hublot Classic is very durable when it comes to withstanding ugly weather conditions. It is known also for longevity in the possession of its users.
Finally, the Replica Hublot Classic is very powerful model that attracts the attention of the youth in particular. This is because of its modern day features that combine artistic attributes and modern sophistications. Many young men therefore enjoy th

As rumors of a touch-screen Apple tablet continue to capture the industry’s speculative imaginations, Apple has sneakily begun setting the stage for a new iPod Touch 3g.

The third-generation iPod Touch, complete with a camera, is expected to launch in September, the same time Apple is supposedly going to drop its “iPad” tablet bomb on unsuspecting Mac-heads.

But Apple still hasn’t confirmed when exactly their annual iPod event will be held, but despite this, AppleInsiderhas gone on the record confirming that it will all go down on Sept 9. They also believe that Apple will finally debut the camera toting 3G iPod Touch in this event and a new iTunes with “social networking” features will also be unveiled. Sadly, though, for those of you expecting an Apple tablet to be announced, they feel that it won’t happen next month.

Anyway, before we get ahead ourselves, you should remember that all of these have yet to be confirmed, and at the end, this is still just a rumor for now. On a good note, however, September 9 isn’t that far away and this does give us something to get excited about for next month.

Finally, show you guys some images of the alleged ipod touch 3g prototype.

The cynic in me still thinks this may be a second-generation Touch that’s had its backing drilled and modified with a convincing camera. It seems odd that beyond the addition of camera, Apple would have left the design of the iPod Touch unchanged.

What do you guys think: real or fake?

PS: Two applied IPod tools:

DVD to IPod converter Rip any DVD movies to ipod touch easily&quickly

Daniusoft IPod transfer – tansfer video/music files during PC, IPod, iTunes as your will.

Another secret by the Apple is “Apple Tablet”. Its basically a large iPhone or iPod touch.  The purpose for introduce this product in this month because Christmas shopping season is near and the Apple wants to open the pendora box again for the  public again .

Screen size: Size up to 10 inches diagonally , touch sensitive.

Phone capability? Not likely , much like a large iPod Touch than an iPhone.

Wireless connectivity: It is same likely iPod Touch. Strong connetivity and range is 10m.

Kindle Rival? Provide the capability to read books, chit chat ,  creating a rival to Amazon’s Kindle.

Launching : By Christmas, At shopping season.
