![]() Orbital emphysema from fracture of the orbital plate (lamina papyracea) of the ethmoidĪlthough most nasal fractures are common and relatively benign, involvement of adjacent structures may produce significant complications.CSF rhinorrhoea from involvement of the cribriform plate of the ethmoid bone.The nasal bones are easily fractured due to them being broad and flat, but proximal nasal bone fracture may be accompanied by fractures of adjacent bones which may lead to additional complications such as: In blunt injuries involving the eye, the globe is more resistant to perforation than the bony orbit is to fracture. In an orbital blow-out fracture, the pressure from a direct blow involving the relatively tough globe is transmitted downwards, fracturing the floor of the orbit, and often results in herniation of intraocular contents into the maxillary sinus. ZMC fractures nearly always incorporate some degree of orbital fracture which become clinically relevant to the EM physician when they involve the orbital floor. The zygoma and maxilla form the greater part of the medial, inferior and lateral orbital margins as well as almost all of the orbital floor. The bony orbit is composed of thickened orbital rims (margins) but relatively thin inner walls. The image illustrates the mechanism of an orbital blow-out fracture. The nerve’s location makes it very vulnerable to both direct injury, and involvement in ZMC fractures. Immediately below the infraorbital margin of the maxilla lies the infraorbital foramen, through which passes the infraorbital nerve (part of the maxillary division of the trigeminal nerve). Temporalis muscle (highlighted) running under the zygomatic arch For clarity the emergency physician (EP) should refer to injuries either to the zygomatic arch or the zygomaticomaxillary complex (ZMC). Other important midface fractures which may be differentiated clinically in the ED are:Ĭonfusingly, many terms exist for fractures to the zygoma and surrounding bones. Which injuries are not covered by these terms and can be separately identified in the ED? those fractures mainly involving the zygoma, maxilla and/or the orbital rim Zygomaticomaxillary complex (ZMC) injuries, i.e.fractures predominantly affecting the zygomatic arch, or How can we avoid confusion when describing these injuries in the ED?įor clinical clarity in the ED, it is suggested that the majority of injuries involving the zygoma and surrounding bones are either referred to as: Whilst it is important to delineate the individual components of a facial injury, in most instances this can only be done accurately by CT scan at a later stage. ![]() The sutures connecting the zygoma to adjacent bones may also be disrupted. Injuries to the zygoma and the surrounding facial bones are confusingly referred to by a number of different terms including:Īll these terms refer to injuries of the zygoma with, in most cases, involvement of the maxilla or temporal bone. Īlthough facial injuries are one of the most common problems seen in the ED, interpretation of facial x rays remains a frequent cause of diagnostic error. While computed tomography is used frequently in trauma, plain x-rays remain relevant in the initial evaluation of potential isolated facial fractures.įacial x-rays were the most commonly misinterpreted radiographs in one study of EM residents in the USA, leading to the most clinically significant errors from all x-ray misinterpretation. Īlthough emergency medicine (EM) physicians encounter large numbers of patients with facial injuries, interpretation of facial x-rays, particularly injuries involving the zygoma, are a common source of diagnostic error in the ED. Of all facial fractures, nasal fracture is by far the most common seen in the ED. Not surprisingly, males outnumber females for facial fractures by a ratio of 2:1. In the 15-50 age group, the most common cause of facial fracture is interpersonal violence, at all other ages it is falls. Anyone who has ever worked in an emergency department (ED) on a Friday night knows that facial injuries are a common presentation.

![]() Open the MasterShots menu on the companion app, select an object, and it will automatically calculate flight paths for various types of shots. Those are all welcome improvements, but my favorite part of the Air 2S is what DJI calls MasterShots. As per usual, Sport mode turns off all obstacle detection use it at your own risk. The Air 2S does lack the side-to-side sensors found on the more expensive Mavic 2 Pro, but its collision avoidance is still a huge step up from previous drones of this size and price. My tests were close: 30 minutes was my max, and I was flying in some windy conditions. As for battery life, the company claims 31 minutes of flight time. I haven't had time to review that one yet, but I've flown it enough to say that the roughly 7-mile (12-km) range claim is accurate-that also applies here. The Air 2S also inherits DJI's O3 flight system (previously called OcuSync) from the company's recent FPV drone. Maybe I'm old-fashioned, but I still have a hard time trusting automation in tight situations. This means you can do more automated flying and worry less about what's around you. The Advanced Pilot Assistance System (APAS) now uses a wider field of view to detect obstacles. This alone is well worth the upgrade from the previous version, but the updates don't stop there. Still, for the size and price, the Air 2S's sensor is hard to beat. On paper, the 1-inch sensor matches what you get in the more expensive Mavic 2 Pro, but the Pro has a variable aperture that can stop down to f/11, which is a huge help when shooting in bright daylight. That's a good choice if you want to crop into the video because you'll still get high-quality clips, though filming at 4K at 60 fps still results in smoother footage in most cases. The new sensor also means you can capture 5.4K video at 30 frames per second. Putting RAW images side by side in a photo editor, it's very easy to see the greater detail, sharpness, and improved definition. It also jumps from 12 megapixels to 20 megapixels for stills. ![]() That's double the size of the one in the Mavic Air 2. That might not sound like an improvement, but I found the Air 2S performs better in windy conditions-more weight likely helps.īut the big difference is the new 1-inch CMOS camera sensor. It's also heavier than its predecessor (595 grams vs. Despite many attempts, I could not get the Air 2S to fly into things in Normal or Cine modes going forward, backward, up, and down. It really helps when you're flying toward something at high speed, since the drone pitches forward, rendering the front sensor slightly less effective. The Air 2S adds an object detection camera to the top of the drone, which improves the collision avoidance system. There are some very welcome changes in this update. It even uses the same batteries, which makes upgrading a little cheaper.īut they're nearly identical. The Air 2S is externally nearly identical to last year's Mavic Air 2. ![]() Limit – Tableau Desktop vs Tableau Public vs Tableau Reader Works with Tableau Mobile to take data everywhere.It keeps data secure on your private servers.If you’d like to keep your data safe and private, you can opt for the Tableau Server.

Other Options Including Artificial GrassĪrtificial grass, loose fill materials, crushed stone, and even natural grass are other options that you can consider. They can also attract insects and pests, which can be a nuisance. However, wood chips require frequent maintenance to prevent compaction and loss of shock absorption. They're also relatively inexpensive and easy to install. Wood chips or wood mulch are natural options that provide good shock absorption and a natural appearance that blends well with most landscapes. However, it can be uncomfortable to walk barefoot, and it may not be the best choice if you have younger children who are more prone to putting things in their mouths. Pea gravel is also low maintenance and doesn't require frequent replacement. Made of small, smooth stones, it's an excellent choice for areas with high rainfall or water runoff. Pea gravel is another affordable option that provides excellent drainage and shock absorption. However, sand can be messy, require frequent maintenance, and may not be the best choice for areas with high rainfall or wind. It provides good shock absorption and can be adjusted to different depths depending on your children's age. Sand is a classic option for playground surfaces, and it's relatively inexpensive and easy to install. However, EWF requires regular maintenance to prevent compaction and loss of shock absorption. EWF provides decent shock absorption and can absorb falls up to 12 feet high. ![]() Made from shredded hardwood, it has a natural aesthetic that blends well with most landscapes. Engineered Wood FiberĮngineered Wood Fiber, also known as EWF, is another popular option that's affordable and visually appealing. It's a bit pricier than other options, but it's an eco-friendly and safe choice for your children. Rubber mulch is also low maintenance and doesn't need frequent replacement. Made from recycled tires, it's a durable and long-lasting option that provides excellent shock absorption in case of falls. Rubber mulch is an excellent choice for parents who prioritize safety and sustainability. In this article, we'll go over the top options for ground cover materials to put under a swing set or playset, their pros and cons, and what to consider when making your decision. With so many materials available on the market, it can be challenging to decide which one is the best fit for your needs. Not only does it provide a safe surface for kids to play on, but it also helps to absorb shock in case of falls. When it comes to building a safe and enjoyable outdoor play area for your children, choosing the right material to put under a swing set or playset is crucial. Top 5 Materials to Put Under an Outside Playset for Safety and Durability In this article, we'll explore the top materials you can use. ![]() One crucial aspect of playground safety is choosing the right material to put under the playset to absorb shock and prevent injuries. However, safety should always be a top priority when it comes to children's playgrounds. Playing outside is essential for children's physical and mental development, and having a play set in your backyard can be a great way to encourage outdoor activities. There's a lot of content that melee classes can complete easy, but if you're playing a melee class it's going to be harder to complete everything compared to a range class. That was pre nerf, but sac is still rediculously good in low level content.Įvery melee class falls off at 200 because a lot of 200 dungeons punish you very hard for getting hit, either by the damage received being too high, or getting -ap or pacifist state, etc. For example at level 150 I did royal masto, royal pingwin, and buckanear solo score 200, then did obsidemon duo score 200 with a lumino. If you play sac you can easily solo dungeons with score 200 all the way through the game. Sacrier is by far the strongest class for just about everything from 1-190, but is mediocre at 200. If you really just want to play through as much of the game as possible solo then Sacrier is your best bet. And because feca has a bunch of strong defensive spells solo quest fights are a breeze. Feca isn't mandatory like panda is, but feca is a very strong pvm class that is always highly useful no matter what you're doing. It is very capable in solo quest fights too. Pandawa is the best pvm class hands down for level 200 dungeons and is almost mandatory for the hardest content. With this in mind my opinion of the best classes to play are either Feca or Pandawa. Given this, if you're only playing 1 account you're going to want a class that is both capable of doing solo quest fights, and also highly desired in a dungeon group so it's easier to find a group to do level 200 content with. Being an MMORPG you'll need to work with other people to get things done once you reach a higher level. ![]() Dofus is not a game you can complete solo. Unlike the F-4, the F-15 was designed for the air superiority mission with little consideration for a ground-attack role the F-15 Special Project Office opposed the idea of F-15s performing the interdiction mission, giving rise to the phrase "Not a pound for air to ground." In service, the F-15 has been a successful fighter, scoring over 100 aerial combat victories and zero losses in air-to-air combat as of 2007. The McDonnell Douglas F-15 Eagle was introduced by the USAF to replace its fleet of McDonnell Douglas F-4 Phantom IIs. It has also been exported to several countries. During these operations, the strike fighter has carried out deep strikes against high-value targets and combat air patrols, and provided close air support for coalition troops. The Strike Eagle has been deployed for military operations in Iraq, Afghanistan, Syria, and Libya, among others. United States Air Force (USAF) F-15E Strike Eagles can be generally distinguished from other US Eagle variants by darker aircraft camouflage, conformal fuel tanks (CFTs) mounted along the engine intake ramps (although CFTs can also be mounted on earlier F-15 variants) and a tandem-seat cockpit. The F-15E was designed in the 1980s for long-range, high-speed interdiction without relying on escort or electronic-warfare aircraft. The McDonnell Douglas (now Boeing) F-15E Strike Eagle is an American all-weather multirole strike fighter derived from the McDonnell Douglas F-15 Eagle. The F-35 can only carry 5,700 pounds, according to F-35 manufacturer Lockheed-Martin.Boeing Defense, Space & Security (1997–present) Each F-15EX, in contrast, can carry nearly 30,000 pounds of air-to-air and air-to-ground weapons. The F-35 enters enemy airspace to identify and engage targets, with superior stealth and sensor technology, says the CRS.į-35s carry weapons in an internal bay to maintain its radar stealth profile. Upgrading F-15s also won't change operational strategy, as the older airframe is supposed to complement the F-35 Joint Strike Fighter, not replace it, as Wired’s Eric Adams pointed out, citing a side-by-side comparison from Air Force Magazine. version of the F-15 is different from those sold to others, the CRS says. In the unlikely event that an enemy combatant is flying the same F-15, there's no need to worry. This is a pretty big deal - especially if the enemy isn't flying F-15s. technology: they've never lost in combat. There's a good reason other Air Forces around the world still fly F-15s, even without U.S. military, they note.Īccording to Air Force Magazine, "The new airplanes would have a substantially more powerful mission computer, new cockpit displays, a digital backbone, and the Eagle Passive Active Warning Survivability System (EPAWSS) - an electronic warfare and threat identification system." About 30% of the American F-15EX would be unique to the U.S. What's new to the F-15EX is an advanced radar and other subsystems that other countries' Eagles don't get. The Eagles of today have stronger airframes, more powerful processors and advanced flight control systems than any the Air Force still flies, according to the Congressional Research Service (CRS). Even though the F-15 first appeared in the mid-1970s, today's F-15 is a lot more advanced than the ones first delivered to the USAF in 1974. |
