Since all ethers contain a C-O-C linkage, the vibration that we would usually refer to as a “C-O” stretch actually involves the asymmetric stretch of the C-O-C moiety as shown in the left side of Figure 2. If both ether carbons are saturated then we have a saturated ether, if both ether carbons are aromatic that gives an aromatic ether, and if one ether carbon is saturated and one is aromatic it is a mixed ether. Here we discuss three different types of ether, which are characterized by the type of carbons attached to the central oxygen. In fact, the only useful group wavenumbers for ethers are their C-O stretching peaks as discussed below. Because ethers do not contain an -OH bond there is no significant hydrogen bonding and there are no -OH stretching or bending peaks. The carbons in these bonds are referred to as ether carbons as shown in the figure. Note that unlike alcohols ethers contain not one but two C-O bonds. Ethers are characterized by a central oxygen atom with two carbons attached, as shown in Figure 1. Now that we are finished with these molecules the next functional group to study that contains the C-O bond is ethers. Also note the carbon-carbon stretches in the aromatic ring (1614, 1506, 1465), the in-plane CH bending (1086, 1035), and the CH oop (738).We discuss three different types of ether, which are characterized by the type of carbons attached to the central oxygen.Ī few issues ago we started our survey of the infrared (IR) spectroscopy of the C-O bond (1), and proceeded to study the spectra of alcohols and phenols (1,2). The characteristic overtones are seen from about 2000-1665. Note the =CH stretches of aromatics (3099, 3068, 3032) and the ≬H stretches of the alkyl (methyl) group (2925 is the only one marked). If you are presented with two spectra and told that one is aromatic and one is not, a quick glance at the sheer multitude of bands in one of the spectra can tell you that it is the aromatic compound. In some instances, it is useful to remember that aromatics in general show a lot more bands than compounds that do not contain an aromatic ring. al., and the Aldrich Library of IR Spectra). Details of the correlation between IR patterns in these two regions and ring substitution are available in the literature references linked in the left frame (especially the books by Shriner and Fuson, Silverstein et. The pattern of the oop CH bending bands in the region 900-675 cm -1 are also characteristic of the aromatic substitution pattern. The pattern of overtone bands in the region 2000-1665 cm -1 reflect the substitution pattern on the ring. Not only do these bands distinguish aromatics, but they can be useful if you want to determine the number and positions of substituents on the aromatic ring. 2000-1665 cm -1 (weak bands known as "overtones").Compounds that do not have a C=C bond show CH stretches only below 3000 cm -1.Īromatic hydrocarbons show absorptions in the regions 1600-1585 cm -1400 cm -1 due to carbon-carbon stretching vibrations in the aromatic ring.īands in the region 1250-1000 cm -1 are due to CH in-plane bending, although these bands are too weak to be observed in most aromatic compounds.īesides the CH stretch above 3000 cm -1, two other regions of the infrared spectra of aromatics distinguish aromatics from organic compounds that do not have an aromatic ring: This is a very useful tool for interpreting IR spectra: Only alkenes and aromatics show a CH stretch slightly higher than 3000 cm -1. Note that this is at slightly higher frequency than is the CH stretch in alkanes. The = CH stretch in aromatics is observed at 3100-3000 cm -1. IR: aromatics IR Spectroscopy Tutorial: Aromatics

Rules Drill bits with diamond tips are more expensive but very durable, and they don't burn out as easily as other bits.ĭrilling through ceramic tile requires patience and time keep a slow steady hand on the drill to prevent damage to the tile. Its important to use the correct type of drill bit at the right speed and with very little pressure. Drill bits with carbide tips need to be used at low speed, and diamond tips need to be cooled to prevent the tips from heating up, which can cause the tile to shatter. Dobrila Vignjevic / Getty Images Ceramic tiles can shatter easily, and drilling a hole into them is tricky. They are both designed to drill into hard surfaces, and both of them puncture the tile with a cone-shaped hole. Tile bits with ground tungsten carbide or diamond tips are the best for this purpose. They come in various lengths, grips, and stylesall so that they can do a great job fastening screws. There are many types of drill bits, for instance, twist bits, installer bits, spade bits, and high-speed drills. Regular drill bits can make a rough and ugly hole, and they may cause the tile to crack. by Clint DeBoer Manufacturers make screwdrivers to fit a wide variety of screw bit types. It's important to use the correct type of drill bit at the right speed and with very little pressure.

Ceramic tiles are coverings manufactured from hard-wearing material. There are now other telescopes in orbit, like the Herschel Space Observatory and the Kepler Spacecraft, which was specially made for finding Earth-like planets around other stars. Hubble will be replaced by the James Webb Space Telescope which will be located even further from Earth. It took the first picture of a planet outside our solar system, and was able to find what type of atmosphere other planets might have.Before the Hubble, scientists only knew it was between 10 and 20 billion years old. It was able to help settle the age of the universe at about 13.7 billion years.In 2004, Hubble looked back several billion years to the first galaxies in the Hubble Ultra Deep Field.It found there were actually many galaxies even there, but very faint and very far away. Early on, in 1994, Hubble stared at what was thought to be an empty area of space for ten days.Sombrero Galaxy in infrared light (Hubble Space Telescope and Spitzer Space Telescope) The astronauts had to think of a creative way to get around the problem. When an astronaut opened one of the doors on Hubble to install a new camera, the door would not close. NASA science games, articles and activities for kids. The astronauts had to install some small mirrors to correct the light from the big mirror. RepairĪnother space shuttle was soon sent up to repair the space telescope. Still, this was enough to cause the images to be blurred. It was only wrong by 2.2 microns (1/50th as thick as a piece of paper). They found a problem with the telescope's mirror. Telescopes in space can take better pictures than telescopes on Earth, but for some reason, the pictures were not better than the pictures taken on Earth. When the HST took its first pictures, astronomers were happy to see the images, but they were not as sharp and as crisp as expected. Improvement in Hubble images after SM1 Problems It was repaired in 1993 due to problems in the picture quality. The Hubble itself is the size of a large school bus, but still small enough to fit inside the cargo bay of a Space Shuttle. This speed creates difficulty in scheduling observations. If you were going this speed on Earth, you would be able to get from New York to San Francisco in 10 minutes. Like other things in low Earth orbit it travels at 5 miles (10 km) per second. It is 600 km in space and was launched on April 24, 1990. It was made by both NASA and the ESA working together. The telescope can take pictures of things so far away it would be nearly impossible to see them from anywhere else. What Is the Hubble Space Telescope The Hubble Space Telescope is a large telescope in space. The main mirror is 94.5 inches (2.4 meters) across. Named after the astronomer Edwin Hubble, the Hubble Space Telescope can observe 24 hours a day. The atmosphere blurs starlight before it reaches Earth. See the fact file below for more information about the Hubble. Being above the atmosphere means it can see the sky more clearly than a telescope on the ground. Named after the astronomer Edwin Hubble, the Hubble Space Telescope can observe 24 hours a day. The Hubble Space Telescope (HST) is the first big optical space observatory telescope.

No food, no blankets, no pillows, nothing. We put each tribe in a separate room with absolutely nothing in it. "We made the decision to bring them to base camp so that we would all be together. This marked the first time that the entire cast was evacuated and that the competitors were able to sleep inside - but they still weren't comfortable. In 2016, the cast of season 33, Millennials v Gen X, had to leave camp due to a cyclone. Of course, there are times when the rules get broken. Instead, they're required to stay with production in a different location - for free! - until the season is done being filmed. Those who don't make the jury aren't sent home. The rules continue after being voted off the island too. For example, the CBS cast must sign a lengthy contract ahead of time, which includes an agreement to be filmed at all hours of the day and "have no expectations of privacy." They also must all disclose their complete medical histories. Some rules are put in place for safety reasons.

If it did, say thanks by subscribing to my channel to see what videos I’m live streaming, now that I’m all fixed up and ready to go! I hope this was useful and helped solve your problem. After doing this, I reloaded the Livestreaming page again, and it loaded OK! I deleted all my keys apart from the Default stream key. This time, copy the id from the JSON that you want to delete and paste it into the id field in the “Try this API” section. Because I’d been changing them around a lot, I figured maybe that was the problem, so I chose to delete them. This screenshot was taken after I fixed the problem – before that I had 4 keys. You can see that I have two streaming keys. To make it easier to read, copy it into a JSON viewer, such as this one. This is the response from the API, and it’s in JSON format. The banner should be green and it should say 200. You’ll be asked to authenticate and approve in a popup window, and then you’ll see the results of the API call shown underneath the Execute button. Make sure that both check-boxes in the Credentials section are ticked, and then click Execute.

I managed to find a way to delete all the keys I’d created, which for me fixed the problem and meant that the Live Streaming page loaded OK again.ĭisclaimer: this fixed my problem, it might not fix yours. What if there was a way to just delete the keys, all the way back to the Default stream key, and start again. So, I wondered if maybe I had messed up the keys somehow. BUT… I’d been playing around with steaming keys, creating and deleting them whilst testing different resolutions and bit rates. Well, I don’t really know what exactly causes it, because I’m not YouTube and they have chosen not to add any super-clear error messages about this. It doesn’t seem to matter how many times you refresh, Private Browser or whatever, always the same. Specifically, some part of the page load is failing with a 500 error: could not fetch broadcast. I’m talking about this error: which you see when trying access the Live Streaming page in YouTube Studio: This blog post is pretty unrelated to what I normally talk about, but I had this problem, didn’t find the resolution on the web anywhere, and then was able to fix it, so I thought it might be useful to someone.

You can get some of these effects by following the best practices, which we’ll show you below. Its mission is laid out in the community description as, “GIFs that are better quality than your mother’s GIFs.” In more specific terms, these GIFs prioritize a few key components: resolution, smoothness, visual effects, and software.

Without needing to send a YouTube link, you can easily embed a perfectly-timed movie reference or reaction into your conversations. And since they get shared so often, the same video gets compressed and looks worse each time it gets saved and re-uploaded.īasically, most GIFs get the job done. It’s hard to make a series of moving images about the same file size as just one static image, like a JPEG. Most GIFs look small and low resolution, like the one above. For as widespread as GIFs have become, they, unlike videos or images, usually look pretty outdated. You’ll probably get teased less if you say it with the hard G and not like the peanut butter brand.Īnyway. So it really depends if you’re a prescriptive or descriptive linguist. You might also ask: is it “jif” or “gif” with a hard G sound? The founder says “jif”. That coffee mug animation? We regret to inform you it was groundbreaking at one point in time. Just take a look at the miraculously-still-maintained Bob Dole 1996 campaign website. With only 256 colors, they’re designed to be efficient, small files, best suited for short clips with pretty similar frames. You might ask: why do GIFs always look pixelated and less colorful than videos? Well, the file format existed back when you needed to unplug your home phone to use the internet. |
