Conceived in the underground era when graffiti kept to the shadows, Nozzle Eye stands as Nick Walker’s emblem. Among his earliest stencil works, this vigilant sentinel embodies sight. An all‑seeing presence that watches and guides, it appears once foundations are laid and intent locks in, dedicated to protecting the...

As the CFM LEAP engine shuts down, you can hear the distinctive “whoosh” sound followed by a gush of air. That is the Reverse Bleed System (RBS) at work. During normal operation, a significant amount of fuel remains unpurged in the system after engine shutdown. This residual fuel, located near or within the hot section, vaporizes due to high temperatures and deposits carbon (coke) on the fuel nozzles. Over time, nozzle coking leads to several operational and maintenance issues, including loss of thrust, reduced engine efficiency due to incomplete combustion, accelerated deterioration of hot-section components (combustor and High-Pressure Turbine), engine start failures, potential engine stalls, and increased unscheduled engine removals. The Reverse Bleed System (RBS) prevents fuel nozzle coking by automatically introducing cool air from the core compartment into the engine core flowpath after shutdown. This effectively lowers the fuel nozzle temperature below the coking threshold. RBS can operate for a maximum of 1 hour, and its effectiveness depends on ambient conditions (especially ambient temperature) and the total duration it runs. The last flight of the day contributes the most to fuel nozzle coke accumulation because of the extended dwell time at the gate. By actively managing post-shutdown thermal conditions, RBS significantly reduces coking-related problems, improves engine reliability, and lowers long-term maintenance costs. Now, also coming soon to the CFM56

🚨There are no links in this post. Please be weary of impersonators. The project will not go live until next week and anything stating otherwise is a scam. 🚨 TLDR: On August 24th I’m releasing an inclusive edition generative project called Heart + Craft, in collaboration with Jordan Lyall, on Prohibition.art, priced at 0.01 ETH. Heart+Craft represents a lot to me. It represents an artistic style and medium that I have expressed since 2014. It represents my present curiosity towards demonstrating value for NFTs beyond scarcity, FOMO, and promise of future value utility. And it represents my vision of a digital optional / physical optional future that I believe can be appealing to a broader consumer audience. Heart + Craft illustrates the potential of art and creativity driven generative goods. On the surface, Heart + Craft is a colorful generative artwork that illustrates my eternal love of gradients, contained in the shape of a heart. There are seemingly unlimited possible combinations of colors and blocks that make up each (Zelda inspired) heart container. But beyond the digital object there is potentially also a physical object, and whether you value the digital or the physical more is entirely up to you. Similar to the concept behind the Friendship Bracelets project, created alongside Alexis André, each Heart + Craft iteration contains detailed instructions for producing a physical analogue. And similar to the bracelets, the value of the digital is not diminished if it is ever separated from its physical counterpart. With this project I’m particularly excited about a lot of things including: The intent that rarity is mostly a function of the complexity of assembling the physical sculpture. The idea that this project could inspire people to take a break from our increasingly digital world, diverting attention to making something tangible that lives in their physical space. The opportunity to spread love and good vibes with a relaxing experience, like building a puzzle, that can lead to personal satisfaction while contributing to a more positive and colorful world. The ability to explore new distribution mechanisms for our digital objects via inclusive editions such as developing kits that come with cubes, paint, glue, and the digital ownership certificate all in a beautiful box. Creating goods where digital objects can inspire a love for craft, and a craft that can catalyze curiosity and foster education for digital objects. Offering a low cost and disarming entry point for new consumers into our space through a project that can be enjoyed as a family, or be gifted to tech/art curious friends, clients, and coworkers. Having another opportunity to perpetuate the beautiful spirit of charitable giving culture that occupies our space by donating a portion of the proceeds in support of the arts. Huge shoutout to Jordan and the VenturePunk ▽✱ team for working with me in bringing this idea to life, the Art Blocks team and Art Blocks Engine for building and supporting the technology empowering a #1of1ofx future, all of the collectors who have instilled the confidence in me to put something like this into the world, and the artists that have played such a huge role in elevating the generative medium. And to my wife, who not only inspires me to put myself out there, but supported this insane journey along with friends and family. I’ve been wanting to do something like this for a long time . Hope you like it and make time to touch some paint here soon. ❤️❤️❤️❤️❤️

Sun-gazing to improve eyesight and eye-health? OK. Let’s break it down. See this video attached? It has more than 1 million views and close to 50K likes. In the video, a guy, who is the co-founder of The Satvic Movement, is trying to "naturalize" the Indians by claiming that everything scientific is “unnatural and synthetic.” He goes on to claim that he got rid of his “glasses” by looking at the Sun, a process known as sun-gazing – during dawn and at dusk which improved his eye health. He gives no scientific explanation for this, apart from a brightly lit well-edited video. Why do people require glasses? These are commonly due to disorders that affect the eye lens – to correct blurry vision that affects distance (nearsightedness – also called myopia), up close (farsightedness – also called hypermetropia), or both, along with difficulty in distinguishing certain shapes (astigmatism). Glasses work to correct your vision and are designed to alter the direction of light rays so that they shine correctly on your retina (the rearmost part of the eye where the light falls to create vision through multi-complex coordination of nerves), allowing you to see properly. These groups of disorders that affect the lens are called refractive errors and wearing spectacles are the easiest and most efficient and safest way to correcting vision in such affected people. Don’t want to wear glasses? There are other effective ways to go about it – such as wearing contacts or opting for a simple, minimally-invasive surgery such as laser-based. Here is a simple explainer on these: Now Sun-Gazing. Sun-gazing is a meditative practice that involves looking at and focusing on the sun. It is usually promoted by unscientific groups, who have close attachments to pseudoscientific practices such as Ayurveda or Yoga and are deeply involved in religion & spiritualism, science-denialism, chemophobia (only modern inventions are chemicals, rest are all natural), irrationality and fearmongering against realistic-healthcare options. The Satvic Movement is EXACTLY that. There is no scientific research to support the practice of sun-gazing. There is no empirical evidence to support that sun-gazing improves eye health or can help you correct eye-lens related disorders. While several bloggers and enthusiasts write about the benefits of sun gazing, no studies or reputable authorities mention or endorse the practice. However, there is evidence that the practice can be extremely HARMFUL. A 1968 paper in the British Medical Journal described people who damaged their retinas - the light-sensitive layers of nerve tissue at the back of the eye that receive images and sends them as electric signals through the optic nerve to the brain – after prolonged periods of sun-gazing. A 1973 paper reported severe damaged to inner layers of the eye after people sun-gazed or focused their vision towards the sun for intermittent/prolonged periods – some where under the influence of LSD recreational drugs. A 1985 report showed that gazing at the sun resulted in fluid leakage and blood vessel damage to the light sensitive structures inside the eye. A 2013 report showed that a woman, after sun-gazing developed persistent vision damage up to one year which required aggressive care. A recent 2022 paper describes in detail the adverse/negative effects seen with sun-gazing and effects of exposure to solar radiation on the eyes. Short-term exposure has been shown to cause photokeratitis and photo retinitis where the cornea of the eye gets damaged. In contrast, long-term exposure has been shown to cause cataracts, pterygium and cancers of the cornea and conjunctiva, and cancers of the eyelids. The evidence supporting these claims is quite compelling. Sun-gazing DOES NOT help you get freedom from your glasses. It will harm you more. It is a primal and primitive practice promoted by loonies who are health-illiterate and dangerous to the public health at large. Do not take health care advice from such people or groups of people. Discuss your healthcare options with your doctor for better understanding and effective outcomes. Stay away from “Movements” that detach you away from reality and leave you without the capacity for rational and logical thinking.
