![]() Atomic clocks use a beam of cesium atoms that are excited by microwave radiation, causing them to vibrate at a precise frequency. ![]() In modern atomic clocks, the oscillation of atoms is used to regulate the clock's timing. These vibrations are used to regulate a timing circuit, which in turn controls the display of the time. In electronic clocks, oscillators are typically based on quartz crystals, which vibrate at a precise frequency when an electrical current is applied. The swinging motion of the pendulum is transmitted to a system of gears and levers, which turn the hands of the clock to display the time. In mechanical clocks, this is often achieved using a pendulum, which swings back and forth at a fixed rate. An oscillator is a device that produces regular, repeating vibrations at a constant frequency. The exact workings of a clock depend on its type and design, but most clocks use some form of oscillator to regulate their timing. The word "clock" enters the language around the 14th century, around the time when clocks started hitting the mainstream.Ĭlocks have played an important role in human history, helping to regulate work schedules, coordinate transportation, and synchronize scientific experiments.Ī clock works by using a system of mechanisms to measure the passage of time and display it in a useful and accurate way. The English word "clock" replaced the Old English word "daegmael" meaning "day measure." Furthermore the word "clock" comes from the French word "cloche" meaning "bell". Clocks are instruments that measure and show the time. Over time, more sophisticated clocks were developed. The earliest clocks were simple sundials, which used the position of the sun to indicate the time of day. Whether for tracking time when cooking and baking or preparing your work presentation, timers are essential to measure, improve effectiveness and boost productivity.A clock is a device that is used to measure and display the time. People can now set their timer for hours, minutes and seconds and choose between different alarm sounds to alert them when the countdown has finished. They are now available in watches, computers, and mobile phones, with new features that could not be found on the analog models. ![]() Analog timers tend to come in funny or unusual shapes to serve as part of the decoration too.Īs technology evolved, digital timers have also become widely used and spread. At a certain point, they even became a necessary kitchen utensil to help cooks know, for example, when it is time to remove a cake from the oven. About timersĪ timer is a clock set to countdown a specified time interval and to sound an alarm when the said interval is over.Īnalog timers have been popular for a long time in many activities since they do not require the users to know the exact hour at that moment. ![]() The size and colors of the widget are completely customizable so you can match it with the overall design of your website or make it more noticeable to your followers.

Low foggers – for when you want the smoke to stay near the groundĪ particular kind of smoke machines are know as ‘low foggers’. Generally speaking, the fog from smoke machines is not meant to stay in the air for very long, but they are great for a quick effect. Fluids are usually marked as light, medium, or heavy.Ĭompared to the other fog options mentioned in this article, smoke particles are big and heavy, and they sink to the floor before dissipating. Smoke machines work by heating a glycol-water-based fluid (with a heating element inside the chassis), which then is pumped out of the machine.ĭepending on the fluid you pour in it, you can control how dense and thick your fog will be. Smoke machines are usually turned on for a short period of time and then switched off again when the desired atmospheric density is achieved. A good, versatile, and powerful (but still mobile) option is the ADJ VF1600 1500-Watt fog machine, which you can find here on Amazon. That is why they are also known as smoke machines.įog machines create white and dense bursts of white smoke clouds, which is great if you want to create the illusion of fire or a smoky poker room in the back of a saloon.įog machines are smaller and lighter and more mobile than hazers.

Troponin is considered an independent risk factor for all-cause mortality in the general population (without ACS). Physiological changes in older patients may be responsible for such results. Low troponin levels are associated more with high mortality in older patients with ACS than with younger patients. However, the prognostic value is attenuated in older patients. Current ESC guidelines recommend that troponin should be measured serially to determine the prognosis in patients with ACS (Class I, level B). High troponin levels predict an increased risk of mortality, and high-sensitivity troponin (hs-Tn)-T seems to be a better predictor than hs-Tn-I. Current European Society of Cardiology (ESC) guidelines recommend the use of NT-proBNP as a prognostic factor in patients with ACS (Class IIa, level B), but the use of other biomarkers is not recommended. An elevated NT-proBNP level in a patient with ACS successfully predicts a worse prognosis (mortality, development of left ventricular systolic dysfunction). It has been suggested that an elevated N-terminal fraction of brain natriuretic peptide (NT-proBNP) level may be caused by transient myocardial ischemia, even without left ventricular systolic dysfunction. 2012 59(23):2091-8.Several biomarkers have been proposed to define the prognosis of patients with ACS, many of which are routinely used in everyday clinical practice. 2-Hour accelerated diagnostic protocol to assess patients with chest pain symptoms using contemporary troponins as the only biomarker: the ADAPT trial.

If patients are in the 0 or 1 point group, they should be further risk stratified using another risk score or one’s own institutional practices, as risk is not low enough to safely discharge from the hospital. Newer chest pain risk scores such as the HEART Score have been shown to better stratify risk than the TIMI Score, particularly in the undifferentiated chest pain patient. Unclear if this risk score can be used in patients with chest pain in the setting of cocaine use. Originally derived with patients with known unstable angina or NSTEMI. TIMI Risk Score for unstable angina/NSTEMI was developed as one of the earliest chest pain decision rules that was widely implemented. Patients who have a higher risk score may require more aggressive medical or procedural intervention. Patients with a score of 0 or 1 point are at lower risk of adverse outcome (death, MI, urgent revascularization) compared to patients with a higher risk score.

![]() ![]() That's why there's a volcano here that's emitting carbon dioxide. There's actually a rift zone that runs across Western Antarctica.Ī rift is where a continent is stretching apart and thinning, which allows hot magma to come close to the surface. That's why there's magma coming up near the surface and feeding this volcano. We're sitting on top of a large feature called the Terror Rift. It seems crazy that anything can live here, in these high altitude volcanic ice towers.īut it also seems pretty weird that in this land of ice, there's an active volcano. Yeah they're crazy, and every one of them sort of has its own personality. ![]() These towers are fascinating because they're castles for exotic bacteria that can survive in the dark, steamy, and nutrient-poor environment. You get all of that gas, water vapor, and carbon dioxide coming up through the side of the volcano, but here, when it hits the air, that steam freezes. On most volcanoes, like this one in Hawaii, they look just like steam seeping out of the ground. Fumaroles are normal volcanic features. These are fumaroles, we call them ice towers. (gentle music) - Sort of like a hollow, upside down icicle. While the most visible activity is at the crater, we're actually standing right next to another scientific marvel. That's how the volcano was built, one lava flow at a time. It's just off-gassing a little bit at a time, and you can see from looking around that it has had eruptive periods that have lava flow associated with them. It's not building up a ton of pressure so it's not like Mount St. They're relatively small eruptions, and release the pressure from inside the volcano.īut these small eruptions are also what keeps McMurdo safe, since pressure is released in small spurts instead of big disasters. ![]() Strombolian eruptions get their name from the Stromboli volcano in Italy, which regularly has this type of eruption. That's where a volcano just builds up some pressure on the inside and then it goes pop, and it blows a bunch of lava out the top of it. It actually has pretty regular Strombolian eruptions. Turns out, getting to the crater rim can be treacherous for another reason, too. It's not so bad being up there, but you have to hike another 2000 feet, uphill. And we're not even at the summit where much of the science is done. It took me a little while to realize he was actually suffering from altitude sickness. At first, I thought Arlo was just spellbound by the view or something. I felt dizzy, I started to have tunnel vision, and I was completely zoned out. (laughs) - When I got off the helicopter, the first thing I noticed was that something wasn't right. The first thing I notice when I get out of the helicopter, my snot is freezing. This is probably the coldest weather I've ever been in in my entire life. Today, we're landing on the flanks of the volcano with Jessie Crane, who's spent three seasons studying the volcanic gases on Mount Erebus. It's one of only eight volcanoes in the world that has one.Īnd this is one of the reasons scientists want to come here. Sometimes you can spot a bubbling lava lake. At Erebus's summit is a crater billowing with gas, mostly water vapor and carbon dioxide from the volcano. When I open the window to take photographs, my fingers go numb.Įxtreme cold at this altitude is no joke. So we use canisters of oxygen to help us breathe. The volcano is 12 1/2 thousand feet high. The remnants of what can happen if we do are still visible. Conditions have to be perfect to fly up to Mount Erebus because we do not want to get stuck up there in bad weather. We've been here two weeks trying to get this flight off. We've been delayed over and over and over again. So, flying is the only practical way to get there. Ross Island is a volcanic island made up of jagged rock, treacherous glaciers, and cracks that can be hard to find. (upbeat music) - Almost everywhere we went, the volcano loomed over us. Mount Erebus is located on Ross Island, just a few miles from the largest research station in Antarctica, McMurdo Station. It's the most extreme Antarctic Extreme. It just makes you get a sense of how small you are in the grand scheme of things. So it's this pretty hulking mass of a volcano. The southernmost active volcano in the world.

This type of workflow could mean that invoice approvals might. That is when the real benefits of e-invoicing become apparent. In some cases, electronic invoices may have to be converted into PDF files and processed manually. The benefits of an e-invoice are negligible or non-existent for the recipient without a smart system that automates invoice processing. The medium an invoice uses to travel between organizations and the way that it is processed is of no concern if it happens quickly and without error. The ultimate goal of a recipient is to book a purchase invoice with as few human actions as possible. The sending party is assured that the invoice will reach the right person faster, at lower costs.
