“We don’t know if they are alive,” Sheinbaum said of the people possibly trapped inside the subway car. Rescue efforts were briefly interrupted at midnight because the partially dangling train was “very weak.” “He is down there now,” he told journalists, pointing to the site.Rescuers work at a site where an overpass for a metro partially collapsed with train cars on it at Olivos station in Mexico City, Mexico, May 3, 2021. He said that his sister-in-law was sent to a hospital, but that his half brother Jose Juan Galindo was crushed and he feared he was dead. Despite the fact that the coronavirus situation remains serious in Mexico City, they crowded together waiting for news.Īdrian Loa Martinez, 46, said his mother called him to tell him that his half brother and sister-in-law were driving when the overpass collapsed and that a beam fell onto their car. On Monday night, hundreds of police officers and firefighters cordoned off the scene as desperate friends and relatives of people believed to be on the train gathered. “I repeat that I am entirely at the disposition of authorities to contribute in whatever way is necessary.” “Of course, the causes should be investigated and those responsible should be identified,” he wrote. The line had to be partly closed in 2013 so tracks could be repaired.Įbrard, who leads Mexico’s efforts to obtain coronavirus vaccines, has been considered a potential presidential candidate in 2024. Mexican Foreign Relations Secretary Marcelo Ebrard called the collapse “the most terrible accident we have ever had in mass transportation.” Ebrard was Mexico City’s mayor from 2006 to 2012, when the affected line was built.Īllegations of poor design and construction on the subway line emerged soon after the Ebrard left office as mayor. Authorities at the time welded steel diagonal braces to the bottom of the beam, chipped out and repoured fractured concrete elements. In 2017, authorities patched and widened the column by injecting resins, swathing it in carbon fibre, building a jacket of additional rebar around the base and pouring concrete around the collar.Īuthorities also found that one of the horizontal beams had come loose from its support at the top of a vertical column and was sagging – the kind of failure that could have contributed to Monday’s collapse. Like many of the dozen subway lines, it runs underground through more central areas of the city of 9 million but is on elevated concrete structures on the outskirts.Ī report issued by the subway system including photos in 2017 showed that the base of one vertical column supporting the tracks had cracked and shed layers of concrete because not enough steel rebar stirrups had been used when it was built around 2010. The collapse occurred on Line 12, the subway’s newest, that stretches to the city’s south side. In October 1975, at least 26 people were killed in another accident. In 2015, a train that did not stop on time crashed into another at the Oceania station, injuring 12. In March 2020, a collision between two trains at the Tacubaya station left one passenger dead and injured 41. The Mexico City Metro – which is among the world’s cheapest with tickets costing about 25 cents – has had at least three serious accidents since its inauguration half a century ago. “Then a guy in a white shirt with blood on his arms, his hands and chest came out and another guy came to help him here on the sidewalk, and he was there trembling,” he said. The overpass was about 5 metres (16 feet) above the road in the borough of Tlahuac, but the train ran above a concrete median strip, which apparently lessened the casualties among motorists.Ībelardo Sanchez, a 38-year-old cook, was just closing up his sandwich shop beside the metro line when he said the ground shook, a tremendous noise echoed, lights flickered and the air filled with dust and the smell of burning wires.

If you notice that the oil level in your C230 is extremely low or empty, fill it up and check it again the next time you drive. If the oil in your C230 is dirty or smells like gasoline, you probably need an oil change. In addition to checking the oil level, you also want to look at the condition of the oil when you have the dipstick out. Otherwise the dipstick will read slightly low. Make sure your engine is cold when you check the oil in your C230. The video above will show you how to check the oil level in your 2003 Mercedes-Benz C230 by taking an accurate dipstick reading. Part : 1-5-40-5QT Line: MOB 5. If you have an oil light illuminate in your C230, this means your oil pressure is either high or low. Note that most Mercedes-Benz have an oil pressure gauge next to the speedometer - this gauge does not tell you what your oil level is, but rather uses an oil sensor to indicate the oil pressure in the engine. Please come back and use the comments section below to help others with your recommendations and what you did differently.Checking the oil in a C230 is fairly easy and should be done once a month.Don’t forget to add OIL to your engine.The bolts need to be tightened to 10 Nm if they have a pre-tapped thread or 15 Nm for a non-tapped thread. Tighten the three screws, preferably using a torque wrench like the torque wrench.Install the new sensor by pushing it in the place of the old one and installing the three screws you removed earlier.There may be some oil that will come out when you remove the oil level sensor B40. Pull the oil level sensor down carefully.Remove the bolts that hold the sensor in place using E-10 socket.You must press the small tab on the connector and pull it out. Unplug the connector to the B40 Oil Level Sensor.Locate the oil level sensor (B40 Oil Level, Engine Oil Temperature, and Quality Sensor) shown in the picture below.You must do this, or the oil will get all over the place when you remove the engine oil sensor later.

The first format calculates the filter output by recursion and the second format calculates the filter output by transform. Filtering of Signalsįiltering of signals by linear systems (or computing the time response of a system) is done by the function flts which has two formats. The fourth element of h1 is set using the function syslin and then using tf2ss the state-space representation is obtained in list form. To convert between state space and transfer function in Scilab, use commands ss2tf and tf2ss. Here the transfer function of a discrete IIR filter is created using the function iir (see Section 4.2). For a system represented by (6) and (7), it is easy to show that the corresponding transfer function equals. The second function ss2tf works in the opposite sense. The first function tf2ss converts systems described by a transfer function to a system described by state space representation. In the event where it is desirable to change the representation of a linear system there exists two Scilab functions which are available for this task. a state-space representation of a given system to an equivalent transfer. Sometimes linear systems are described by their transfer function and sometimes by their state equations. State space matrices for a transfer function can be calculated as follows using Scilab: mpc/matrix.txt SScont (in the last line above), has the value of the. Overall transfer function, block diagrams reduction techniques and Masons gain. State-space descriptions of systems in Scilab use the syslin function.

In: 40th fluid dynamics conference and exhibit, Chicago Gross A, Fasel H (2010) Numerical investigation of separation for airfoils at low Reynolds number. Mueller TJ (1985) Low Reynolds number vehicles, AGARD-AG-288 Further validation of the airfoil using wind tunnel testing is recommended and planned. The optimized airfoil can be used in the applications of UAVs as well as in general aviation. The newly generated airfoil exhibits improved aerodynamic characteristics as compared to the base airfoil. The use of the transition-sensitive turbulence model allowed the evaluation of the behavior of the laminar separation bubble for different angles of attack, observing that it shifts towards the leading edge and has its length reduced as the angle of attack increases. The optimization results are further compared with the results of the numerical simulations. The proposed “software integration methodology” demonstrated up to 10% improvement in the optimization parameter which makes it more efficient by reducing the optimization time and steps without unnecessary user intervention which are the limitations conventionally associated with the optimization process. A simple design optimization methodology with the integration of XFOIL in the modeFRONTIER workflow environment is proposed in this study. The airfoil SG6043 is used as the reference airfoil for optimization due to its common applications when long-endurance characteristics are desired. XFOIL is used as an aerodynamic solver while modeFRONTIER workflow is employed for the design optimization purpose. This study aims to develop a simple and efficient design optimization methodology for the low Reynolds number airfoils. one is narrower, tapering towards the end, and has a straight edge. For the Anastasia applicator, the spatula is wide and has a rounded end. There isn’t a major difference in the spoolie ends - both have firm bristles and can be bent for the optimal application angle if you wish - but the spatulas vary in shape and size. each offer a dual-ended applicator with a spoolie at one end and spatula at the other. Once I got over this learning curve, however, the Brow Lift gave the same full, feathered brow effect I wanted.Īnastasia and E.l.f. Plus, the more I tried to work the product through my brows, the stiffer they would become as the gel dried - and be warned, overworking the product leads to some flaking (this is true for the Anastasia product too, but it was easier to avoid with the Brow Freeze since I didn’t have to fidget with setting them in place as much). With the E.l.f option, I found I have to use even less product than the Brow Freeze (like literally the least amount of gel possible) or else my brows would stick together and then I wouldn’t be able to get the fluffed up look I was after. While a light hand should be used for both, the Brow Freeze was easier to brush through my brows and set them in place. I got the hang of it by the second application, but the first time testing it resulted in some sticky, over-gelled brows. The clear gel-wax has a slightly sticky feeling and you’ll immediately feel it give the brows a stiffening effect when its brushed through.įor me, the Brow Lift was a bit more finicky to use than the Brow Freeze, but still an effective product. The Brow Freeze and Brow Lift virtually look and feel the same, both in the jar and on the brows. All you have to do is brush a tiny bit of the gel-wax through your brows with a spoolie, shaping them in your desired arches. But instead of having to wet them like you would with bar soap, the gel-wax format of the brow products doesn’t require any extra steps to activate and you can apply them straight from the pot. The ingredient is also found in the formulas of Brow Lift and Brow Freeze, giving them flexible and even conditioning hold (glycerin is a moisturizing ingredient for the hair and skin). Glycerin is the key ingredient in bar soap that coats the brows and keeps them in place.

Is he a threat in the bantamweight division? Should they do it a fourth time, with the score now tied at 1-1-1 after three bouts?īeyond Saturday's title fights, Said Nurmagomedov moved to 4-1 in the UFC with a clinical submission victory in less than a minute. It was the most entertaining fight of the night, and Figueiredo seemed to have elevated his game after moving his camp to Arizona to work with Henry Cejudo. UFC 270 takeaways: Figueiredo and Moreno aren't done with each other yet spotlight shines on prospectsĭeiveson Figueiredo exacted revenge on Brandon Moreno in their trilogy fight to win back the flyweight title at UFC 270 at the Honda Center in Anaheim, California on Saturday. That may not sound like much fun to the rest of the contenders at 125 pounds but it would appear inevitable that Figueiredo and Moreno will meet again before 2022 is over.You have reached a degraded version of because you're using an unsupported version of Internet Explorer.įor a complete experience, please upgrade or use a supported browser I need to watch the fight again to see what happened.”Ĭonsidering their first meeting ended in a draw with Moreno winning the rematch and then Figueiredo getting revenge in the trilogy, it’s going to be awfully hard to avoid a fourth fight between the flyweights. I felt I was putting a better pace on the fight. “Obviously I feel like I won but it is what it is. “I feel like I threw better combinations with more speed,” Moreno said following the fight. While Moreno certainly made a strong showing late, it was Figueiredo’s ability to hurt him earlier in the round that likely swayed the judges in the end. Just when it looked like the momentum was swinging towards Moreno with time ticking towards the end of the fight, Figueiredo fired off another powerful right hand that puts the Mexican born flyweight down on the canvas before he quickly bounced back up to his feet.įigueiredo connected with two more hard right hands late but then Moreno just invited him into a fire fight, which resulted in “The Assassin Baby” unloading with some nasty punches that also connected flush. Moreno continued to push the pace with Figueiredo more resigned to throw a single power punch at a time while making sure to keep his hands up to avoid the champion’s fast hands. Moreno was the busier fighter, constantly throwing combinations with Figueiredo suddenly slowing down as the flyweights prepared to step out for the final five minutes. Time ran out before Figueiredo could capitalize but that helped him stunt whatever momentum Moreno had started to build.ĭespite being dropped, Moreno did not slow down in the championship rounds as he sought to secure his first title defense. The left hand continued to pay off but then just before the horn sounded, Figueiredo uncorked a massive right hand that sat Moreno down. A second later as Figueiredo pushed forward, Moreno countered by blitzing him with punches including a left hand that staggered the Brazilian. In return, Moreno unleashed a multi-strike combination with a jab and a left hand over the top that slipped through Figueiredo’s defense and appeared to wobble him at least momentarily.Īs the third round got started, Figueiredo cracked Moreno with a hard shot that sent the flyweight champion stumbling backwards before ultimately rolling and getting back to his feet. As Moreno started to increase his output, Figueiredo was putting a little bit more pop behind his punches, which led to a solid left hand landing flush. Figueiredo was dedicated to those calf kicks, which continued to tag Moreno as the first round came to a close.įigueiredo continued to dig to that lead leg while Moreno targeted the head with some fast and explosive punches that came from different angles. Looking for a better start than the rematch, Figueiredo looked to establish some early leg kicks but Moreno showed great patience while firing back with some quick counters that backed off the Brazilian. Each number on the magnitude scale indicated an earthquake 10 times stronger than the last-which means the quake strength between each increment of one on the scale grows as the numbers climb. Richter's idea was to track the amount of energy released by a quake the way an astronomer would measure the brightness of a star. The Richter Magnitude Scale is the method of earthquake measurement widely used in the United States last century. "My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star," said Charles Richter-the scientist behind the well-known scale of the same name-in a 1980 interview. The answer, it turns out, begins in outer space. So why do geologists talk about earthquakes this way? Why not use a scale that operates more like the ones used to measure weight, or length, or temperature, or any number of other natural phenomena? And a 7.0 releases 31.622 times as much energy as a 6.0. But no! In reality, a 6.0 quake releases 31,622.776 times as much energy as a 3.0 quake. This is what a casual observer of earthquake magnitude scales would expect: that an earthquake of 6.0 packs twice the punch of a 3.0. On a linear scale, we know that four is twice as big as two and eight twice as big as four. Here's how Jesse Singal explained it over at New York magazine earlier this year: None of this jibes with the linear way people use numbers for most measurements in daily life. Which means a 6.1 magnitude quake like the one that shook Northern California over the weekend is about twice as big as the 5.8 earthquake that rattled Washington, D.C., in 2011-and nearly three times as strong in terms of the amount of energy it released. Some more context: The 7.0 earthquake that devastated Haiti in 2010 was eight times bigger than the Northern California quake, and released 22 times more energy. But that number is based on a logarithmic scale, and can be hard to grasp.Įarthquakes aren't measured linearly, but in orders of magnitude. Today, along with those accounts, we would also get a number: the magnitude of the earthquake. These details help convey the staggering scale and reach of what was a remarkable geologic event. Two hundred years ago, Missouri was rocked by an earthquake so severe it made the Mississippi River flow backward and set off church bells in Boston more than 1,000 miles away. |
