![]() ![]() Erebus is a stratovolcano composed of alternating layers of solidified ash, hardened lava, and rocks ejected by earlier eruptions. This Mount Erebus image shows a fairly typical level of activity for the volcano, including a molten lava lake and vapor emissions. Since that time, EO-1 has been successfully employed to detect other volcanic eruptions, including those near densely populated areas. Scientists who subsequently examined the data EO-1 acquired confirmed that a genuine thermal emission had been detected. After the initial detection, the satellite gave itself new orders to take fresh observations of the volcano several hours later. On May 7, 2004, the Autonomous Sciencecraft Experiment on EO-1 first demonstrated its ability to detect volcanic activity by sensing thermal emissions at Erebus. The larger image shows a true-color, photo-like view of the volcano, and the inset image shows thermal activity, highlighting the volcano’s molten lava lake. The larger image was acquired by the Advanced Land Imager (ALI), and the inset image was acquired by the Hyperion sensor. This image shows two views of Mount Erebus from February 6, 2009, captured by sensors on NASA’s Earth Observing-1 (EO-1) satellite. In 2004, the reliable presence of a lava lake at this volcano’s summit made Mount Erebus the perfect place to test a self-directed satellite and sensor. The world’s southernmost volcano to show activity during recorded history, Erebus holds a lava lake and occasionally experiences explosive eruptions. ![]() Antarctica’s Mount Erebus may be covered with glaciers, but they do little to cool the volcano’s molten core. ![]()

![]() ![]() Simply put, sports massage will help you to reach your training goals quicker.Ĭlosely linked to point 2 on feeling tense, many people who experience a lot of headaches can benefit from massage. It’ll loosen knots, allow you to maintain and increase flexibility and will also improve blood flow and prevent the build-up of lactic acid. Not only will sports massage help with the aches and pains following a training session it’ll reenergise you, assist healing and the prevention of any injuries. Depending on your level of training and what you’re aiming to achieve, your massage therapist may focus on a particular area, or your body as a whole. Sports massage is a really important part of any training schedule. They’re also skilled in finding areas of tension and knots, and while sometimes a little uncomfortable, the relief that can be experienced following a massage is well worth it. Our muscles can get tight when we forget to relax, and a massage therapist will work on releasing tension from the soft tissue in any problem areas. One of the most common reasons people book a massage is because they feel tense. It’s non-intrusive and can be used on just about any part of the body, so don’t discount massage for your problem before speaking to a professional. Massage works to alleviate pain through manipulation of muscles, tendons, ligaments, and fascia and just a short session can make an immediate difference to your levels of discomfort. If you’re experiencing tenderness from sore muscles or aches from stiffness or overuse, a massage could be what you need. So, what are some of the signs you’d benefit from massage? Here’s our lowdown on how massage can help and the cues to look out for: In the same way that we may recommend Pilates, acupuncture or shockwave therapy alongside your physiotherapy regime, massage can be the perfect addition to maximise your fitness. ![]() But did you know a massage has huge health benefits and is much more than a luxurious treat? It also perfectly complements physio.

DVD players also usually read discs at a constant linear rate.Audio CD players read their discs at a precise, constant rate (4.3218 Mbit/s of raw physical data for 1.4112 Mbit/s (176.4 KB/s) of usable audio data) and thus must vary the disc's rotational speed from 8 Hz (480 rpm) when reading at the innermost edge, to 3.5 Hz (210 rpm) at the outer edge.The second hand of a conventional analog clock rotates at 1 rpm.Modern air turbine dental drills can rotate at up to 800 000 rpm (13.3 kHz).Phonograph (gramophone) records, for example, typically rotate steadily at 16 + 2⁄ 3, 33 + 1⁄ 3, 45 rpm or 78 rpm (0.28, 0.55, 0.75, or 1.3, respectively, in Hz). On many kinds of disc recording media, the rotational speed of the medium under the read head is a standard given in rpm.The conversions between a frequency f and an angular velocity ω are: The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines."Ī corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the radian per second.Īlthough they have the same dimensions (s −1), hertz (Hz) and radian per second (rad/s) are two different units and are used to measure two different but proportional ISQ quantities: frequency and angular frequency (angular speed, magnitude of angular velocity) respectively. It defines a unit of rotational frequency equal to s −1. ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min −1) is a unit of rotational speed or rotational frequency for rotating machines.

The Razer Basilisk Ultimate is a high-performance 20K DPI gaming mouse that'll leave its mark on more than just the leaderboards. See our full Logitech MX Master 3S review. While that does mean you could probably bag the still impressive MX Master 3 for cheaper, and we will continue to demand a left-handed version of this mouse until the company listens, this true all-rounder with zero compromise will always be a sound investment. Packed with some of Logitech’s most premium features, this peripheral isn’t exactly a budget buy, and picking one up could set you back as much as $99. ![]() That means you can be confident in its performance and uptime. The Darkfield high-precision sensor resolution has been upped to 8000 DPI for ultra accuracy and responsiveness, the click switches are a lot quieter, and the company's done all this while still maintaining that same 70-day battery life. Its seven well-placed buttons afford a high level of customization for any task at hand, and two machined steel scroll wheels make vertical and horizontal navigation of even the largest documents a breeze.īut while the improvements are subtle, they make the experience all the more impressive. While you won’t see the MX Master 3 topping any lists as the best gaming mouse, it remains entirely serviceable in all but the most ultra-competitive of games thanks to its comfort and accuracy.
