Why are the airplane windows oval?

Have you ever noticed that the windows of airplanes always oval and not a square? This may make some of you wonder. A video released recently offered a simple explanation.

The key words why the oval-shaped was chosen due to the flight safety only. As quoted of the Daily Mail on Thursday, January 21, 2016, the box-shaped airplane windows will result in a buildup of pressure on the corners. Meanwhile, the rounded windows drastically reduces the possibility that the pressure buildup.

It is probably something many fliers will have never stopped to consider - but a recent engineering video explains just why it is so vital they have their current shape. (Picture from: http://dailym.ai/1PjL2kI)

On a video made by Real Engineering using a diagram to explain the pressure flow through the cabin during the flight. Also presented a number of points in the window that increased pressure.

"The corners of a box can collect pressure and can lead to failure due to structural fatigue," explains Dai Wittingham, the leader of the British Aviation Safety Executive Commission explained to MailOnlineTravel.

"The designers prefer the oval shaped windows because it provides a wider viewing space commensurate with height most passenger when sitting."

The shortest part of the oval shape was designed so that the curve does not create an unsafe pressure to the material in the vicinity.

"Lately we have started to see there are a number of designers who choose a more square shape, but always with a curved corner."

Early jets such as the de Havilland Comet featured windows of a square design and suffered several accidents and fatalities as a result. (Picture from: http://dailym.ai/1PjL2kI)

In early jets have square windows and the aircraft designers was scientifically realized the mistake after it was too late. It is seen on the first commercial jet airliner, the De Havilland Comet, when the plane was destroyed in the air in 1954.

The plane has a rectangular-shaped windows. The investigation revealed that one of the windows become a source of structural failure, killing everyone on board.

Air pressure differences inside and outside of the aircraft caused the fuselage slightly expands and in such circumstances, sharp corners on the window adds to the pressure. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL]

Ducati draXter Concept

Ducati Dragster Concept enliven the Motorbike Expo 2016 event in Verona, Italy which has been held since January 22, 2016 last. The drag-racing motorcycle concept implies the variant of Ducati xDiavel which newly launched on November 2015 at the EICMA 2015 in Milan.

The Ducati draXter Concept is a project of Advanced Design style, a part of the Ducati's design team, ie the Ducati Design Centre. Cursory, this concept is similar with the xDiavel.

The Force 1: Michigan’s V10 Supercar That Defied the Future

Unbridled Power - In today’s era of electric domination and AI-assisted driving, the raw, untamed sound of a naturally aspirated V10 feels almost mythical. Yet, some machines refuse to be tamed by trends—and one of the boldest examples ever built came straight from Michigan: the Force 1, a ferocious American supercar that still echoes through automotive history as a celebration of power, craftsmanship, and pure audacity.

Back when it first roared onto the scene, the Force 1 wasn’t just another limited-edition exotic. It was a statement from VLF Automotive, a small yet fearless carmaker founded in Michigan by three automotive legends—Henrik Fisker, Bob Lutz, and Ben Keating. Each brought something unique to the table: Fisker’s mastery of design, Lutz’s deep understanding of performance engineering, and Keating’s unshakable passion for the Viper racing world. Together, they set out to build a car that would embody the soul of American muscle while stepping boldly into the realm of world-class supercars.

The result was breathtaking. With only 50 units ever produced, the Force 1 instantly became a collector’s dream. Its design language was unmistakably Fisker—sleek curves blending with sharp, aggressive lines, and a muscular stance that made no apologies. You could still trace its Viper heritage in the side exhaust and long hood, but everything else screamed evolution. The carbon fiber bodywork shimmered under the light, the roof gleamed with a glossy finish, and every surface seemed sculpted for speed.

Underneath that beautiful chaos lived its heart—a monstrous 8.4-liter V10 engine, pushing a staggering 745 horsepower at 6,100 rpm and 928 Nm of torque at 5,000 rpm. It wasn’t just powerful; it was primal. That energy shot straight to the rear wheels through either a six-speed manual gearbox for purists or an optional six-speed automatic with paddle shifters for those who wanted a taste of modern ease. With a top speed of 350 km/h (218 mph) and the ability to catapult from 0 to 60 mph in just 3 seconds, the Force 1 didn’t merely perform—it attacked the road.

Stopping such a beast required serious hardware, and VLF didn’t compromise. Brembo brakes came standard, gripping massive 21-inch alloy wheels wrapped in Pirelli P Zero tires—305/25 ZR21 up front and 355/25 ZR21 in the rear. The balance between brute force and engineering precision made driving the Force 1 a true sensory event. Even its weight, a mere 1,538 kg (3,395 lbs), felt perfectly tuned to keep the car agile despite its massive powertrain.

Step inside, and the aggression gave way to refined simplicity. The interior, built purely for two, wrapped its occupants in luxury and intention. Every surface whispered exclusivity—an atmosphere that reminded you this wasn’t a car built for everyone. At a price tag of $268,500, the Force 1 demanded both courage and commitment. But those who dared were rewarded with an experience that few cars could match—a thunderous reminder of what happens when passion meets precision. 

Years later, as the automotive world speeds toward a future of silence and sustainability, the Force 1 stands as a symbol of resistance—a beautiful, roaring rebellion from Michigan’s heartland. It may no longer be the newest supercar on the block, but its spirit remains timeless. The Force 1 wasn’t created to follow trends; it was made to defy them. And that, perhaps, is what makes it unforgettable. *** [EKA [27012016] | FROM VARIOUS SOURCES | VLF AUTOMOTIVE | WORLDCARFANS | MOTORAUTHORITY ]

Is bearded man more hygienic?

According to research conducted recently shows that the beard is thought to contain good bacteria which can be developed into new antibiotics. And researchers found shave to clean can make a man stricken with infections, bacteria develop antibiotic resistance, when compared with those who had beards.

As quoted from the Independent on Thursday, January 21, 2016, the study published in the Journal of Hospital Infection, by conducting tests on 408 samples from the face of the hospital staffs (with and without the beard).

(Pictured: Vin Diesel with beards on 'The Last Witch Hunter' movie.) Beards may be more hygienic and bacteria-resistant than shaven skin, study finds. (Picture from: http://bit.ly/1NzljgS)

The result showed that people who clean shave beard, three times more susceptible bring a staph bacteria that is resistant to most of antibiotics named 'Methicillin-Resistant Staph Auerus (MRSA)' on their cheeks.

At the same time, 10 percent of men are likely to have colonies of a positive bacterium named 'Staphylococcus Aureus,' which produces a yellow pigment on the face. This bacterium causes skin infections, respiratory and food poisoning.

The scientists also suspect this is causing mikrotrauma resulting from sideburns to the skin, supporting the development of bacterial colonization and proliferation.

The study conclusion noted: "Overall, a similar colonization occurred in health workers with or without a beard, but certain species of bacteria commonly found in workers without a beard."

Dr. Adams Roberts, a microbiologist from the University College London, was able to breed more than 100 different bacteria from the sample by analyzing the different beard. The result finds the existence of microbes that can kill other bacteria.

Dr. Robert separates microbes and test it with a type of E. coli that cause urinary tract infections. He found that the microbe is able to kill bacteria efficiently. This leads to inventory existing antibiotics become less effective, with the presence of antibiotic-resistant infections that killed at least 700,000 people each year.

Until now, there has been no new antibiotics issued since 30 years ago. Dr Roberts considers this invention is similar to the success of Alexander Fleming who discovered penicillin. The discovery was inadvertently occurs when fungal spores exploded into one of the sample being studied.

At the time, Flemming realized that the bacteria had died he developed only in the area affected by the explosion of spores. However, further research from an accidental moment that led to the penicillin which we know today. *** [EKA | FROM VARIOUS SOURCES | INDEPENDENT]

The Recidivist, the increadible first tattooed-motorbike

Tattooed human skin is common in the world of graphic arts. Currently, most of the motorcycle decorated in the style of tattoo motifs using airbrush paint, but what if the custom motorcycle laced with shades of the art of tattoo?

A Polish automotive modifier workshop called Game Over Cycles able to prove it by building a custom motorcycle named Cheyenne Bike 'The Recidivist,' where the whole frame and body covered with cowhide and then tattooed like human skin. Built-in collaboration with German company Cheyenne Professional Tattoo Equipment and Dutch Zodiac Performance Products for Harley-Davidson, the bike is both a tribute to motorcycle engineering and a work of art.

This bike is built to take on the basis of a Harley-Davidson Heritage Softail. Its basic color tends to black directly polished evenly by the tattoo artist. Polish tattoo artists Tomasz Lech and Krzysztof Krolak have spent 250 hours to make the motorcycle full of tattoos, by using the equipment of renowned tattoo equipment dealer, named Cheyenne Professional Tattoo Equipment.

Here are several pictures of parts of the tattooed custom bike. (All pictures are taken from: http://bit.ly/1lNdpKp)

Together they managed to make the motorcycle 'tattooed' first in the world. This bike success tattooed because the parts to be stained with ink has been specially coated with cow skin-colored modified the technology so much like human skin.

The Recidivist be so unique because of the tank, seat and rear fender is covered by a genuine leather filled with a variety of tattoo images. Because the builder wants totally play artistry on the entire body of the motorcycle, then no exception from the front to rear wheels also wrapped in cowhide.

The retro design of the machine is an even more glorious, as the builders managed to integrate elements specific to the tattoo world and maintain their full functionality. The coil tattoo machine dampers of the springer fork and the custom exhaust which looks like a tattoo machine in action are only two of the most obvious such elements. Thus, essentially as a custom motorcycle even more neat and harmonious.

The world first tattooed motorcycle appeared in public for the first time during the Custombike Show in Bad Salzuflen, Germany earlier in December 2014. This event is one of the biggest exhibition in the world motorcycle modification. On its uniqueness, The Recidivist was greeted with enthusiasm and was even able to snatch the title of "Best Paint/Airbrush" at the event. Let's see the video below;

Overall, the bike is different than the most custom motorcycle. And of course, for the tattoos lovers, the custom motorcycle like this is perfect for your daily riding vehicle.

Kept spur your adrenaline on the power of the two-wheeled monster and stay alive with true safety riding. May God will forgive Your sins and so does the cops...... *** [EKA | FROM VARIOUS SOURCES | GAME OVER CYCLES | AUTOEVOLUTION]

"I know that anyone who is fortunate enough to drive the 3-Eleven will be fascinated by the performance that can only be given by a light weight and the addition of power," says the CEO of Lotus, Jean-Marc Gales.

The sports cars built on a special chassis made, the system is able to stop the 3-Eleven Lotus comes from AP Racing 4-piston brakes with two-piece discs grooved and vented in both versions, while the Race type get a different brake pad. Lotus 3-Eleven will be sold in Europe and Asia as a street car and in all markets as a race car and will only be built as many as 311 units world wide. *** [EKA | FROM VARIOUS SOURCES | CARSCOOPS]
