Keep Your Car Cool with the Mercedes Benz Radiator

Mercedes Benz was formed through the merging of two companies namely the Daimler-Motoren-Gesellschaft (DMG) and Benz & Cie in June 28, 1926. DMG was founded by Gottlieb Daimler and design partner Wilhelm Maybach in 1890 while Benz & Cie was founded by Karl Benz.
Basing from its history, it is interesting to note that Karl Benz, one of the founders of Mercedes Benz, was the one who first invented the first automobile water radiator.The Mercedes Benz radiator is a part of your car’s cooling system. To keep the engine from overheating is the primary job of the cooling system and it does this by transferring heat to the air since 70% of the energy in the gasoline is converted into heat. Since it keeps your car from overheating, The Mercedes Benz radiator therefore plays a very important role in all internal combustion engines. It is connected to several channels running through the engine and cylinder head, through which a liquid which is usually a mixture of water with ethylene glycol and is called anti-freeze is usually pumped through. This liquid flows through a thermostat and back again to the radiator. Through this process, heat is conducted away from the engine parts, making the vehicle safe from overheating.The Mercedes Benz radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. Nowadays, most of the modern cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator. The Mercedes radiator is commonly mounted behind the car’s grille. This is done to make sure that the fluid stays inside and also because cold air is driven through it in this location. There is also a system of valves installed to simultaneously operate a small radiator called the heater core inside the car. This small radiator serves to warm the vehicle’s interior cabin.The size of the radiator is also taken into consideration in such a way that it can keep the engine at the design temperature under the most extreme conditions a car is likely to encounter. The Mercedes Benz radiator should be checked-up regularly to maintain optimum performance. What could go wrong with it if not maintained properly? First of all, your radiator might overheat. A leaking radiator might be another problem. It is therefore important to check if the radiator is filled with water. When it does overheat and you’re in the middle of the road, don’t panic. First, pull over and stop. Turn of your air conditioning to reduce engine temperature and you can also turn on your car’s heater and set in on the highest temperature setting. Open the hood of your car and let the engine cool off. Check the overflow tank coolant level but be very careful since serious burns can occur because of extreme heat. If it’s empty, then the radiator is probably low on coolant. Check also the pressure of the system by wrapping a cloth around the upper radiator and squeezing it. Aside from this problem of making you pull over every now and then, overheating can not only shorten your engine’s life but can also cause huge damage on your engine. It is therefore important to check the radiator regularly to avoid inconveniences and serious engine problems in the future.

Several conflicts involving civilians occurred in East Timor at the same time that Australian-led peacekeeping troops stormed a town where a rebel former army officer and his men have been under siege.
The Australian soldiers, supported by helicopters and armored vehicles, stormed the town of Same, 50km south of the capital Dili, at dawn.
Four armed East Timorese men were killed and two others injured during the operation, but their leader, Major Alfredo Reinado, escaped the troops.
The operation was authorised by East Timor’s president, Xanana Gusmão, after Reinado refused to negotiate.
The Major was directly involved in the clashes with the government forces last May, and was later jailed by Portuguese troops for having in his possession dozens of weapons and explosives that he hadn’t handed over to the Australian troops in charge of disarming the rebels. Reinado escaped during a mass breakout from a Dili jail last August.
After the Australian-led operation started, many conflicts occurred simultaneously in different parts of Dili, with roads being barricaded and cut off by burning tires, rocks and trees. Many houses and vehicles were also burned, as violence between rival groups started on the streets.
The Vila Verde neighborhood, right in the center of Dili, was one of the most affected, with facilities of the Education Ministry being engulfed by a fire until the morning.
Benjamin Marty, finance manager for the Norwegian Council for Refugees in East Timor, has his house and office in Vila Verde, in the same street that connects the Portuguese Corporation Neighborhood to the United Nations Integrated Mission in Timor-Leste (UNMIT) headquarters.
“I didn’t get too worried when a saw a group of people starting to hit the gate, but I called my boss, that said me to stay calm.” Bryn Bithell-Marty said.
“Ten minutes later, I see the GNR arrive and starting to fire rubber bullets to the right and to the left” of the street, Marty remembered.
“They called and asked me to open the gate, but initially I didn’t understood what they wanted, because I don’t speak Portuguese. Just in some minutes, I was inside a armored vehicle, and we got out of there at the same speed that they had arrived, deviating from the barricades with a lot of skill”, Marty added.
Benjamin Marty said he was “surprised with the professionalism” with which the Portuguese Republican National Guard (GNR) acted, but he was discontented with members of the United Nations Police (UNPol).
“There’s UNPol near my house, the patrol cars were always stopped and the police agents didn’t do anything», Marty said, adding that the UNPol agents also didn’t react “hours early when some people started to burn tires and hitting metal to call other people to the street”.
The clashes in Taibessi, Pité neighbourhood, and at the entrance of the UNMIT headquarters were the most severe, involving firearms in some locations.
In Banana Road, one of the main roads that crosses the city, a group of teenagers guarded a poster of Alfredo Reinado.
“We are the defenders of Major Alfredo, hero of the justice. We are ready to die to defend him”, said one of them.
In the streets of Taibessi since some days ago that the illumination posts and some trees have posters and banners of Alfredo Reinado.
As a response to the successive attacks by a group on the Pité neighborhood, 15 Portuguese Public Security Police (PSP) officers, organized themselves without orders from the UNPol, and for three hours the 15 officers faced the attacks.
Later back at the GNR headquarters, Benjamin Marty, found himself even more surprised. “Do you know how the Asterix and Obelix stories end?” he said. On the GNR headquarters there wasn’t a party with roasted boars, like in the Gaul village, “but there was a cow in the skewer”, he added.
All of the three GNR operational platoons then left their monthly festivity to the streets of Dili, for a operation that lasted seven hours.

The US commander of the Multinational Security Transition Command in Iraq said that he had no knowledge of the National Strategy for Victory in Iraq document released by the US President. This, along with speculation that the document was chiefly authored by a public opinion analyst recruited by the White House have led to some critics claiming that the drafted ‘strategy’ is targeting US public opinion, not the Iraqi insurgency.
The military, political and economic strategy for Iraq, outlined last week by President Bush in a speech at the Naval Academy in Annapolis, Maryland, was based by a 35-page document titled the National Strategy for Victory in Iraq. A metadata tag on the document posted on the White House website identified its author as a computer user ‘feaver_p’. It is believed to refer to Dr. Peter D. Feaver, a special advisor to the National Security Council staff.
A political scientist at Duke University, Dr. Feaver analyzed public opinion polls about the Iraq war and attitudes towards war casualties. Dr. Feaver found that US public opinion will support military engagement abroad, despite growing casualties, provided that the public believed that the war was being fought for a worthy cause and that victory was achievable.
Dr. Feaver was one of the people who helped “conceive and draft” the document, according to a White House staffer, who said that Meghan L. O’Sullivan, the deputy national security adviser for Iraq and Afghanistan, and her staff played a larger role. White House officials confirmed to the New York Times that the document’s “creation and presentation strongly reflected the public opinion research”.
The document “reflects the broad interagency effort under way in Iraq” according to an NSC spokesman Frederick Jones and had received major contributions from the Departments of Defense, State, Treasury and Homeland Security, as well as the director of National Intelligence.
On Friday, Lt. Gen. Martin Dempsey, whose Multinational Security Transition Command is responsible for building Iraq’s security forces, told reporters that he had seen the strategy document for the first time when it was released to the public. The White House had said that not all senior officers in Iraq had necessarily seen the document and Gen. Peter Pace, the chairman of the Joint Chiefs of Staff, has said that he had read and critiqued the document on several occasions.
Earlier, replying to questions about the President’s strategy, White House press secretary Scott McClellan said that the document was an “inter-agency document” and an “unclassified version” of the administrations “strategy for victory in Iraq” published for the public to view.
Christopher F. Gelpi, of Duke University, who co-authored Dr. Feaver’s work titled Casualty Sensitivity and the War in Iraq, stated, “The Pentagon doesn’t need the president to give a speech and post a document on the White House Web site to know how to fight the insurgents. The document is clearly targeted at American public opinion.” In their work together, Gelpi, Feaver and Reifler found that the most important factor which determines the US public’s tolerance for US military deaths in a war is the public’s beliefs about the likelihood of success, and a secondary, but still important, factor, was found to be the public’s belief in the rightness of a war.

Indonesian authorities said earlier today that they have uncovered a plot by rebels to assassinate several senior government officials, among them president Susilo Bambang Yudhoyono.
National police chief Bambang Hendarso Danuri commented on the matter earlier today, saying that several rebels intended to conduct the attack and declare an Islamic state during the August 17 independence day ceremony. “They were confident that all state officials and dignitaries would be there. Killing all the state officials would have accelerated the transition from a democracy to a state controlled by Islamic Shariah law,” he said.
Danuri added that the attacks also included a plan to attack foreigners and hotels in the capital Jakarta — somewhat similar to the 2008 Mumbai attacks that killed 174 after rebels attacked tourist spots like hotels and a train station.
“Their plan was also to launch attacks in Jakarta against foreigners — especially Americans — and attack and control hotels within certain communities, imitating what happened in Mumbai,” the police chief said. “If we had not detected them and their military training had been successful, then they would have assassinated foreigners.”
The plot was revealed in part due to several anti-terror raids near the capital, which saw twenty people arrested. Many of those now in custody were reportedly trained at a camp in Aceh, and operated by a branch of the Jemaah Islamiyah group called al-Qaeda in Aceh.
This is reportedly the second alleged plot to assassinate the Indonesian president in a year; last August, security forces said they had evidence suggesting rebels would blow up a car by Yudhonoyo’s motorcade. The last large rebel attack was in last July, when suicide bombers targeted hotels in the capital.

Boston-based singer-songwriter Antje Duvekot has made a name for herself in the folk music world with powerful ballads of heartbreak and longing for a deeper spirituality, but coming up empty-handed. Below is David Shankbone’s interview with the folk chanteuse.
David Shankbone: Tell me about your new album.
DS: You mentioned you used to explore more dark themes in your work, but that lately you are exploring lighter fare. What themes are you exploring on this album?
DS: What were you going through that made it so dark?
DS: What personal relationships do you struggle with?
DS: Do you believe in a higher power?
DS: What do you believe?
DS: Why do you miss having religion in your life?
DS: Does the idea that our lives on Earth may be all that there is unsettle you?
DS: You had said in an interview that your family wasn’t particularly supportive of your career path, but you are also saying they were atheists who weren’t curious about the things you are curious about. It sounds like you were a hothouse flower.
DS: They almost sound Soviet Communist.
DS: What’s your relationship with them now?
DS: Why?
DS: That’s the reason you don’t speak with them?
DS: That must be a difficult thing to contend with, that a career would be the basis for a relationship.
DS: Would you say in your previous work some of your conflict of dating would have been birthed from how your relationship with your family? How do you see the arc of your work?
DS: Has the Iraq War affected you as an artist?
DS: How has it affected you personally?
DS: The struggle to be original in art is innate. When you are coming up with an idea for a song and then you all of a sudden stumble across it having been done somewhere else, how do you not allow that to squelch your creative impulse and drive to continue on.
DS: When I interviewed Augusten Burroughs he told me that when he was in advertising he completely shut himself off from the yearly ad books that would come out of the best ads that year, because he wanted to be fresh and not poisoned by other ideas; whereas a band called The Raveonettes said they don’t try to be original they just do what they like and are upfront about their influences. Where do you fall in that spectrum?
DS: Who would you say are some of your biggest influences in the last year. Who have you discovered that has influenced you the most?
DS: You moved out of New York because you had some difficulty with the music scene here?
DS: Do you feel home up in Boston?
DS: Why do you think Boston has such a well-developed folk scene?
DS: Is there anything culturally about Boston that makes it more conducive to folk?
DS: Do you have a favorite curse word?
DS: Really?! You are the first woman I have met who likes that word!
DS: Do you find yourself more inspired by man-made creations, including people and ideas, or nature-made creations?
DS: What are some man made things that inspire you?
DS: Do you think you will return?
DS: What trait do you deplore in yourself?
DS: When is the last time you achieved a goal and were disappointed by it and thought, “Is that all there is?” Something you wanted to obtain, you obtained it, and it wasn’t nearly as fulfilling as you thought it would be.
DS: What is a new goal?
DS: How challenging is it to obtain that in the folk world?
DS: Do you think of doing something less folk-oriented to give your career a push?
DS: More money more problems.
DS: What things did you encounter doing a studio album that you had not foreseen?
DS: What is your most treasured possession?
DS: Please! Do tell!
DS: You found a latex glove in a parking lot and you decided to take it?
DS: If you could choose how you die, how would you choose?
DS: Would you be an older woman with long hair or short hair?
DS: Who are you supporting for President?
DS: You don’t think Obama would have a chance of winning?
DS: What trait do you value most in your friends?
DS: What trait do you deplore in other people?
DS: Where else are you going on tour?
DS: And you have to fly up there!
DS: Is there a big folk scene in Alaska?
DS: So you had that sense of what Ani DiFranco must feel.
DS: Did you like that?

Eric Bogosian is one of America’s great multi-dimensional talents. “There’s sort of three different careers, and any one of them could exist by itself, on its own two feet. There was that solo stuff, and then I started writing plays in the late seventies.” Although his work has spanned genres, most readers will recognize Bogosian for his acting, which has included a memorable performance in Woody Allen‘s Deconstructing Harry to co-writing and starring in the Oliver Stone movie Talk Radio (based upon his Pulitzer Prize-nominated play) to playing the bad guy in Under Siege 2 to his current role in Law & Order: Criminal Intent as Captain Danny Ross. They may not know, however, that he had collaborated with Frank Zappa on a album, worked with Sonic Youth, and was a voice on Mike Judge‘s Beavis & Butthead Do America. He started one of New York City’s largest dance companies, The Kitchen, which is still in existence. He starred alongside Val Kilmer in Wonderland and his play Talk Radio was recently revived on Broadway with Liev Schreiber in the role Bogosian wrote and made famous.
Currently at work on his third novel, tentatively titled The Artist, Bogosian spoke with David Shankbone about the craft of writing and his life as a creative.
Saturday, March 5, 2005Simply massaging low birth weight babies with sunflower seed oil can protect them from potentially fatal infections.
Infections and complications from preterm birth cause more than half of all neonatal deaths, and very low birth weight babies are particularly vulnerable.
Preterm babies have immature skin that lacks a protective film called vernix that has antimicrobial properties.
In some countries, such as India, newborns are routinely massaged with mustard oil.
But mustard oil, says Gary Darmstadt of John Hopkins University in Baltimore, Maryland, can delay recovery of the skin barrier and have a toxic effect on skin.
Seeking an alternative low-cost product, Darmstadt and colleagues experimented with sunflower oil and an ointment called Aquaphor that comprises petrolatum, mineral oil, mineral wax and lanolin.
The researchers tested the treatments on 497 newborns (72 hours old or less) and preterm babies (less than 33 weeks gestation) between 1998 and 2003 in Bangladesh.
They applied the treatments to the entire body besides the scalp and face three times daily for the first 14 days and then twice daily until discharge.
Babies treated with sunflower oil were found 41% less likely to develop infections than controls.
“Evidence is emerging that the skin is much more important as a barrier to infection than previously recognized, particularly in preterm infants whose skin is underdeveloped,” says Darmstadt. “The good news is that treatment is available to strengthen the function of the skin as a barrier in these vulnerable newborns.”

Background
Many new drug molecules have solubility problems with some having almost no aqueous solubility. This creates formulation development issues since many standard formulation techniques may not be successful in delivering a drug orally. A common approach to improving oral delivery is to use the amorphous form of an active pharmaceutical ingredient. The amorphous form will have higher apparent solubility compared to its crystalline counterpart. This improvement in apparent solubility can be a strategy to increase oral absorption and bioavailability when in-vivo dissolution is the rate-limiting step. In general, the increased surface area exposure of the amorphous form can decrease time for drug to solvate and be absorbed.
Benefits
The key benefit of the higher apparent solubility is a faster dissolution rate which may lead to higher bioavailability when poorly water soluble drugs can be enhanced with this technique. The higher dissolution can also improve exposure with a more rapid onset and some cases allow a lower dose than needed for a crystalline form of the drug.
Downsides
The major disadvantage of using an amorphous form is their enhanced properties are offset by the decreased physical and chemical stability relative to the crystalline form. Amorphous solids are metastable and may recrystallize during storage,. Another limitation occurs during dissolution where trace amounts of crystalline drug may act as nucleating agents when the drug is introduced to aqueous media. Another issue is when an amorphous solid is undergoing dissolution. The supersaturated solution generated in the dissolution media around this solid is thermodynamically metastable or unstable and may undergo a phase transformation to a lower free energy state. At supersaturation there will be a thermodynamic driving force for crystallization from solution to a more stable crystalline form. If this phase transition takes place rapidly, the actual supersaturation will be much lower than expected and the benefits of the amorphous form will be lost.
Techniques
A common technique to stabilize an amorphous form in solid state and to protect from phase transition during dissolution is to formulate the drug as a solid dispersion. This formulation is a mixture of the API in the amorphous form with a solid dispersion with a second component, such as a polymer. The stabilizing of amorphous APIs has been attributed to an antiplasticization effect since solid dispersions typically possess higher glass transition temperatures than the pure amorphous drug thus resulting in a lower molecular mobility that prevents phase transition. The stability may also be due to formation of specific drug-polymer interactions such as hydrogen bonds.
There are many cases where the addition of a polymer significantly delayed the onset of crystallization in the solid state. This physical stabilization has been attributed to several factors, such as reduction in molecular mobility, reduction in the thermodynamic driving force for crystallization, increase in the energy barrier for crystallization, disruption of molecular recognition necessary for drug crystallization, or a combination of these factors. Regardless of the specific mechanism, drug polymer blends are more resistant to drug crystallization than the amorphous drug alone. Polymers that are commonly used to stabilize the amorphous state during storage include HPMC, HPMCAS, HPMCP, CAP, Eudragit and Povidone.
An approach is to use an amorphous dispersion where there is an intimate mixture of a drug and a polymer in which the polymer disperses the drug and helps to maintain it in an amorphous form. In this system the drug is dispersed on a molecular level and its release is controlled by erosion of the polymer framework rather than by the dissolution of the drug. This can provide a dissolution pattern that is an independent mechanism of controlled release.
The formulation development team has a number of techniques available to stabilize amorphous drugs with polymers. In a dispersion processes, the API and polymer are heated until they melt or a molten drug or dissolved in a molten polymer. The melt is then extruded, cooled and milled. In a spray drying process, a solution of the drug and polymer in a common solvent is sprayed and dried thus forming a highly concentrated drug/polymer gel also known as a solid solution. The hot melt extrusion has gained popularity for preparing solid dispersion due to many advantages, such as free of solvents, simple procedures and uniform product quality. Co-crystallization is another solid state approach which improves the apparent solubility of the without compromising its structural integrity and bioactivity.
Conclusion
In the formulation development of poorly soluble compounds, forming and stabilizing the amorphous drug has become an important approach when attempting to produce a drug product that will perform consistently over time. These formulations can maintain the performance benefit of an amorphous form while preventing phase transitions during storage thus allowing for the development of viable pharmaceutical products containing a poorly soluble drug.
