The first submarine was built by Dutch engineer Cornelis Drebbel in 1620, but it stuck to shallow waters. The challenging process requires a very narrow beam with a high frequency to offer a clear picture of where objects might be. In the days before the submersible’s likely implosion was confirmed, search and rescue teams relied on sonar, a technique that uses sound waves to explore the opaque depths of the ocean, to attempt to pinpoint the vehicle in case it had been stranded on the seafloor. Jamie Pringle, a reader in forensic geoscience at England’s Keele University, in a statement. “Aquatic search is pretty tricky, as the ocean floor is a lot more rugged than on land,” said Dr. Many of the factors that made the multiday search for the vessel so difficult are also the reasons a comprehensive exploration of the ocean floor remains elusive. The disaster could have occurred during the submersible’s descent, as pressure on the vehicle grew. The US Navy later revealed that it had detected a sound on Sunday that would match an implosion, indicating the vessel, called the Titan, was rapidly destroyed. Operated by OceanGate Expeditions, a private company based in Washington state, the tourist vessel lost contact with its mother ship after departing on Sunday. The remnants of the ship lie about 900 miles (1,450 kilometers) off the coast of Cape Cod, Massachusetts, and about 12,500 feet (3,800 meters) underwater. The submersible, which is believed to have been destroyed in a catastrophic implosion, killing all five people aboard, was en route to explore the wreckage of the RMS Titanic. The environment is dark with almost no visibility. There’s a reason deep-sea exploration by humans has been so limited: Traveling to the ocean’s depths means entering a realm with enormous levels of pressure the farther you descend - a high-risk endeavor. Gene Feldman, an oceanographer emeritus at NASA who spent more than 30 years at the space agency. In fact, “we have better maps of the moon and Mars than we do of our own planet,” said Dr. ![]() ![]() While 12 astronauts have spent a collective total of 300 hours on the lunar surface, only three people have spent around three hours exploring Challenger Deep, the deepest known point of Earth’s seabed, according to the Woods Hole Oceanographic Institution. Researchers often say that traveling to space is easier than plunging to the bottom of the ocean. Though people have been exploring the ocean’s surface for tens of thousands of years, only about 20% of the seafloor has been mapped, according to 2022 figures from the National Oceanic and Atmospheric Administration. The submersible vehicle that was lost at sea is part of a relatively new effort enabling tourists and other paying customers to explore the depths of the ocean, the vast majority of which has never been seen by human eyes.

But I cannot come up with a situation in which silently dropping the mail is better than rejecting it during the SMTP transaction. In those cases it makes little difference if you reject the RCPT TO command or if you accept the mail and silently drop it. There may be cases where distribution of the email-address in the first place was so limited, that you know there couldn't be any legitimate mail send to the address. Sending bounces from your mail server is a problem, because in that case spam bounces to some innocent person's mailbox instead of back to the spammer.Silently dropping the mail is a problem, because if any legitimate mail was sent, the sender can never know that it wasn't delivered.This is a problem, because you have no proper way out. if your mail server responds with success all the way through the transaction including at the end of DATA, then it becomes the responsibility of your mail server to deliver the mail. I do however see a problem in accepting the mail. (And if that's what they wanted to do, they could have done so without even trying to deliver the mail to you in the first place.) In case of spam, it means the spammer will have to generate bounces. Your mail server took no responsibility for the mail, and the sending mail server is now responsible for bouncing it. In both cases, the end result will be the same. You can either return an error on the RCPT TO command, which is what usually happens in case of a non-existent address, or you can return success on the RCPT TO command but return an error at the end of DATA. What are the pros and cons of each approach?Īs long as you bounce the mail by refusing to receive it in the first place, then a spammer cannot use you to annoy somebody innocent with a lot of bounces. Also, I keep discovering new spam traps and adding them to my "spam black hole" list, which is a waste of time. I can just delete the item from my aliases file and the email will bounce. The benefit of bouncing them is that it is less maintenance for me. i.e.: forge the "from" line to be someone they don't like, then use me to send tons of bounce messages to that person. The benefit of sending the email to /dev/null is that a spammer can't use me to generate bounce messages (Backscatter spam). However I'm not sure what to do about the hundreds of accounts that were used for other purposes, such as throw-away accounts I used to use for websites that asked for my email address, or address that I used to list on web pages.įorward all mail to these accounts to /dev/null. If the account was used by a person, I let the email bounce so that anyone trying to contact them knows something is wrong. Many of them receive literally thousands of emails a day, all spam. I have a lot of unused (old, dead) accounts on my machine. ![]() ![]() Test your luck on one of our beautifully designed and immersive digital slot machines.Feeling a bit bored?

Various gas sensing technologies have been developed 7, traditional gas sensors with metal compounds as sensing materials detect gases at high temperatures and show excellent performances 8. Gas sensors play an important role in the detection of hazardous gases, inflammable gases, air pollution, human health and agricultural automation 2, 3, 4, 5, 6. Long-term exposure to 35 ppm of NH 3 is hazardous to human health 1. The excellent performance of the sensor shows that it has potential for applications in food safety, environment, and human health monitoring.Īs a poisonous gas, NH 3 is produced in many industrial processes and the natural decomposition of organic matter. More specifically, AgNPs enhanced the adsorption capacity of RGO for NH 3 electrons. The enhanced NH 3-sensing performance is mainly due to the synergistic effect between Ag and RGO. By combining the material with a commercial near-field communication (NFC) tag, a wireless gas sensor was built. X-ray diffraction (XRD), Raman spectroscopy, and field emission scanning electron microscopy (FE-SEM) were used to analyze the crystalline structure, material composition, and surface appearance characteristics of the sensing material. A simple, environmentally friendly, and cost-efficient green approach for the preparation of the sensing material is proposed. In this paper, we present reduced graphene oxide (RGO) decorated with silver nanoparticles (AgNPs) as a sensing material for NH 3. The detection of ammonia (NH 3) in low concentrations is very important in the chemical industry and for human health. ![]() This requires the artist to be patient as the painting develops, gradually adjusting as each layer is applied. Often it requires many layered applications to build up the color to level of complexity. There is no mixing of colors prior to application and colors can be quickly adjusted once they are on the surface.Īlthough we benefit from this characteristic, it's important to note that pastels are at their best when they are layered. One of the more appealing aspects of pastels is the immediate gratification of applying colors. Blues, purples, and oranges provide color contrast and the strengthen the illusion of light in the background - the "star of the show". Silhouetted elements in the middle ground and foreground enhance the lighter tones in the sky.

I'm speaking as the father of Nancy right now, but, in a sense, I'm speaking for all the proud, happy, and tearful parents gathered here this morning, most of whom, unfortunately, probably missed breakfast. She's the most interesting interrupter I've ever met. It's been years since I've had the opportunity to speak this long to my daughter without her interrupting. For the privilege of letting me address this gathering, what you've given me is a great deal of satisfaction. I don't know how much help I've given you today, but I can say this. ![]() I firmly believe that if you follow a path that interests you, hopefully with a passion, and if you bring to it a sense of your own worth, not to the exclusion of love, sensitivity, and cooperation with others, but with the strength of conviction that you can move others by your own efforts, and do not make success or failure the criteria by which you live, the chances are you'll be a person worthy of your own respect. They have a cousin who took out Meryl Streep's baby sitter.'' They're more talented, they're taller, blonder, prettier, luckier, and have connections.

It was one of those canvas wooden chairs that you use at the beach. In 1983, Miami University appointed me dean of arts and sciences for the Fontainebleau Hotel. In 1982, Cornell University made me an honorary bachelor of arts at Syracuse University. To be frank, I thought a humane letter was, ''Dear Sir, we have decided not to kill your dog.'' In 1981 Hofstra University awarded me an honorary doctor of humane letters. I have received other such awards, proudly. Would you let an honorary mechanic fix your brand new Mercedes?. Actually people with honorary awards are often looked upon with disfavor. Will I be invited to the homecoming games on the 50 -yard line, or will I receive two honorary tickets which entitle me to listen to it on local radio?. Am I now more intelligent or am I just honorarily smarter?. The last thing I am is ungrateful for this generous and gracious acknowledgment, but to be perfectly honest I'm not exactly sure what an honorary doctorate affords me in life. As a matter of fact, it was my SAT scores that led me into my present vocation in life - comedy. You must realize that honorary degrees are generally given to people whose SAT scores were too low to get them into the school the regular way. I would, of course, like to extend my gratitude to the powers that be at Williams for graciously bestowing upon me an honorary doctorate in letters. Driving up here yesterday with road directions given to me by my daughter, I thought I would be the commencement speaker for the Class of '85.
