![]() Portrait sized work is well served by the Inspire1000 in the digital line, and by the Tracer in the opaque projector line. If you’re doing close in, smaller sized work, especially if you can occasionally dim the room lights, a less powerful projector will work just fine. You can get that size with clarity if you can dim the lights in an opaque like the Super Prism.These projectors are physically larger and heavier than other models, so won’t be as easily portable and need sturdy platforms or stands to hold them. If you’re doing wall murals in a brightly lit area, you’ll need a brighter, more powerful projector, probably one of the higher-end digitals, like the Impression1400. The power/brightness and physical size of both your working conditions, and your artwork surface and type need to be considered. How do my working conditions and artwork type relate to my projector choice?.Look at our Where to Buy section to find retailers. Many retailers may offer lower prices than our MSRP. MSRPs of our new line of LED digital Art Projectors, plus a comparison of features, are on our Digital Projector page. If your source materials are primarily printed, you may prefer an opaque projector. Lenses vary with our line of opaque projectors, some allowing both enlargement and reduction of the original image. Opaque projectors usually require a darkened room to operate effectively. Opaque projectors are the traditional style of projector which shines a bright light on a paper such as a photograph or illustration, or a three dimensional object like a small statue, and projects that image. Digital projectors are also bright and most can work in reasonably well lit rooms. You can manipulate the image right on the projector, for example change it from color to black & white and back, or enhance edges. It can also project live images from, for example, your phone’s camera, and play videos, project PDF files, PowerPoint files, or Word docs. ![]() Do I want a digital projector or an opaque projector?ĭigital projectors operate from images stored on your computer, smartphone, flashdrive, or tablet.Below are some things to consider to help you get on the right track: ![]() You must first determine what your needs are. ![]() Projectors are among their most valuable tools.

At this point, I mentioned to Heaton that I was in fact speaking to him from an office building in downtown San Francisco. And since 1906, San Francisco has built a lot more tall buildings downtown. Another is that tall buildings are more vulnerable to long, slow lurches of the ground that only occur in huge quakes. New and ugly things happen when earthquakes get past 8.0 or 8.5. “This confusion over earthquake magnitude seems to be creating a lot of confusion in the design of buildings,” says Heaton.

Definition of moment magnitude scale in the dictionary. “Seismologists were saying people understand magnitude. It’s more logical than Richter but also more layperson-friendly than seismic moment. A 5.0 earthquake might be equivalent to 400 Akis-so that a tiny 2.0 could be measured in milli-Akis and a devastating 9.0 in billions of Akis. This definition appears somewhat frequently and is found in the following Acronym Finder categories: Science, medicine, engineering, etc. It was defined in a 1979 paper by Thomas C. Moment is a product of the distance a fault moved and the force required to. “It feels almost sacrilegious, but I have to say it.” Instead, she proposed a scale based on seismic moment using Akis, named after the inventor of the seismic moment, Keiiti Aki. The moment magnitude ( MW or M) scale, developed in the late 1970s by Japanese seismologist Hiroo Kanamori and American seismologist Thomas C. How is Moment Magnitude Scale (seismology) abbreviated MMS stands for Moment Magnitude Scale. The moment magnitude scale (MMS denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ('size' or strength) based on its seismic moment. The moment magnitude scale is based on the total moment release of the earthquake. “I hate the Richter scale,” she began the piece. ![]() Seismologists use seismic moment-which, remember, is basically energy released-to compare earthquakes because it does get at the totality of an earthquake rather than the shaking at just one particular place in the ground.īack in 2000, Jones wrote an article in the Seismological Review Letters suggesting a new earthquake scale. In other words, the relationship between shaking amplitude and earthquake energy from Richter doesn’t hold for all earthquakes, and moment magnitude doesn't easily translate to earthquake intensity.

P-waves have different morphology (at least three)Ī premature atrial contraction (PAC) is generated by a depolarization instigated outside of the SA node. This rhythm is benign, and once the underlying lung disease is treated, it should resolve. MAT frequently occurs in the setting of severe lung disease and, more specifically, during an exacerbation of lung disease. Figure 1.4: Three distinct P-wave morphologies in a case of MAT. By definition, MAT must have at least three distinctly different P-wave morphologies (figure 1.4) and a ventricular rate of greater than 100 bpm. Thus, each QRS complex will be preceded by a P-wave however, each P-wave will have a different morphology because they originate from different areas. The multiple foci within the atrium generate consecutive action potentials that are all conducted to the ventricles. ![]() The multiple foci result in P-waves with multiple morphologies and irregular intervals (see figure 1.4). The pathophysiology of MAT is not clear, although several theories exists (e.g., triggered activity, reentry, or abnormal automaticity). Multifocal atrial tachycardia (MAT) is caused by the presence of multiple ectopic foci. Parasympathetic stimulation or changes in AV node refractoriness can modify how many P-waves pass into the ventricle, but the the resultant rhythm is “regularly irregular.” When the heart rate is elevated, then distinguishing flutter from fibrillation becomes challenging and slowing ventricular rate pharmaceutically (adenosine) helps the flutter waves reemerge for a definitive diagnosis to be made. The slower reentry current produces an atrial rate of 250–350 bpm (compared to the 400–600 of atrial flutter), and P-waves are present but have a characteristic “sawtooth” pattern (figure 1.3 and middle panel figure 1.2).Īs with atrial fibrillation, the AV node’s refractory period prevents most of the P-waves from progressing to the ventricle, but commonly the AV conduction will be 2-to-1, so with an atrial rate of 300 bpm the ventricular rate will be 150 bpm. The cavotricuspid isthmus (CTI) usually provides the circuit for the slower reentrant current to become established (typical atrial flutter), but other sites of reentry and slow conducting circuits are possible (atypical atrial flutter) and are usually associated with structural heart disease or sites of previous surgical or ablations procedures. ![]() Figure 1.2: Comparison of atrial arrhythmias, including atrial fibrillation (left), atrial flutter (middle), and multifocal atrial tachycardia (MAT) (right).Ītrial Flutter Figure 1.3: Atrial flutter - “sawtooth” P-waves with lower frequency than the fibrillation waves of atrial fibrillation.Ītrial flutter is caused by a macroreentrant current, rather than the multiple sites of aberrant depolarization seen in fibrillation. When this occurs, the ventricular rate rises to 100–200 bpm, and QRS complexes can be “irregularly irregular” with a varying R-R interval (left panel, figure 1.2). This means the ventricular rate does not rise to 400–600 bpm (which would be catastrophic), but some of the atrial fibrillation activity can be “lucky” and reach the AV node when it is not in a refractory period. The rapid atrial depolarizations are transmitted to the atrioventricular (AV) node, but far from all are conducted through to the ventricle because of the node’s long refractory period. Because the atrial rate is so fast, the ECG shows “coarse fibrillatory waves” (figure 1.1) the action potentials produced are low amplitude, and P-waves will not be seen. Causes include hypertension, valvular and ischemic heart disease, and genetics (e.g., mutation of 10q22– q24 on chromosome 10). The rapid depolarizations result in a very fast atrial rate from 400 to 600 bpm. These aberrant depolarizations are often the result of myocardial remodeling and frequently originate within the muscular sleeves that extend into the pulmonary veins from the atria. Atrial Fibrillation Figure 1.1: An ECG of atrial fibrillation showing lack of P-waves and low-amplitude fibrillation waves between QRS complexes.Ītrial fibrillation is the most common cardiac arrhythmia and is caused by rapidly firing potentials in the atrial myocardium. Learning the arrhythmias here will be substantially easier with a robust understanding of electrocardiogram (ECG) fundamentals and lead orientation, so going back to basics is likely to be very worthwhile. ![]() This chapter will address the arrhythmias listed in the USMLE (United States Medical Licensing Exam) Step 1 content guide on a section-by-section basis. ![]() This is a story about the psychology of a creature with near-limitless power who is beyond ethical concerns. Ainz Ooal Gown seems to have modifications made to his behavior by in-game mechanics, because he demonstrates no moral qualms with killing and other actions that are taboo in the real world. Taking on the name of the guild, Ainz Ooal Gown, as a message to any other remaining players, Momonga begins exploring the world in an attempt to figure out what has happened while searching for anyone or anything that could help him solve this mystery, while ensuring the safety of Nazarick. With no other option, Momonga sets out to learn if any players like himself are in this new world. Momonga has been trapped in the form of his game avatar, leaving him unable to use the normal player functions such as General Message, or even log out. When the shut-down time arrives, Momonga discovers that the game hasn't vanished instead, it appears as if Nazarick has been transported to another world altogether and its various NPCs becoming actual living beings. While saddened by this, he accepts the reality that his friends have their other lives to take care of and decides to stay logged in until the servers shut down. In the minutes before the shutdown he invites the remaining guild members, but of those only one appears and only for a short while before leaving. Now only four of the members remain, the other 37 having quit the game, and only one, a skeletal Lich "Overlord" character named Momonga, continues to play as the guild leader, maintaining their headquarters in The Great Tomb of Nazarick. Within the game exists a guild, Ainz Ooal Gown, once consisting of 41 members and credited as one of the strongest guilds in the game. After an intense twelve-year run, the game servers are about to be shut down.

Be gentle when removing and inserting the headgear.Patients who wear their headgear appropriately can usually be finished with it within a year.The more consistently you wear your headgear, the less total time you will ultimately need to wear it.In other words, after school, after dinner, and all night as you sleep. Wear the headgear at least 14 hours per day.The inner part of the headgear slides into tubes on the side of the first molar teeth. The headgear uses the back of the neck (see photo) as an “anchor” to correct this relationship. This appliance may also be used to prevent the upper back teeth from slipping forward during space closure in patients who have had extractions for bite correction. This condition is often responsible for the appearance of protruded upper front teeth or “buck teeth” and can also cause an excessive vertical overlap of the front teeth or “deep bite.” This appliance is used when there is a difference in growth between the upper and lower jaws, such that the upper teeth and jaw are too far forward of the lower teeth and jaw. Remember, though, that the archwires going through the brackets will still be visible. These brackets are less noticeable because they are the same color as your tooth. For mature teens and adults, we also offer ceramic brackets. Different colored “ties,” which hold the archwire to the bracket, may be chosen at each appointment. The photo above illustrates one type of braces we offer. Without proper hygiene, the patient is at risk for developing decalcification (white marks) on the teeth, cavities, and puffy, overgrown gum tissue. This debris is easy to remove with thorough and proper brushing and flossing. Braces attached to the teeth provide many more places for food particles and plaque to accumulate. Oral hygiene, including tooth brushing and flossing, is EXTREMELY important during orthodontic care. ![]() It is just strong enough to keep the braces on during treatment, but must be weak enough so the braces can be removed when treatment is complete. A special type of glue is used to bond the brackets to the teeth. Traditionally, full braces involve bands that are placed on the molar teeth (which wrap entirely around the tooth) and brackets bonded to all other teeth. Be especially cautious with your diet to avoid bending or breaking the springs.īraces are the mechanism we use to “get a handle on the teeth.” In other words, they merely provide an attachment with which we can grab and move the teeth.Brush carefully around the springs to keep everything clean.They are usually worn for three to four months.Forsus springs will cause some discomfort the first few days.The springs work EXTREMELY well because they are not removable and ensure a constant force on the teeth.

If headgear wear is poor, then Forsus springs may offer an acceptable compromise. ![]() They are NOT a substitute for headgear though. They have almost the same effect as rubber bands and are primarily used when patients have proven to be uncooperative with rubber band and/or headgear wear. This appliance is recommended when baby teeth are lost prematurely, so the space may be maintained.įorsus springs are used in cases where the upper teeth are forward of the proper fit with the lower teeth. The lingual arch is a metal bar that is attached to the tongue side of the lower first molar bands, and form-fitted behind the teeth. We commonly use this appliance for patients who have an impacted permanent tooth, and exposure of that tooth is suggested. The transpalatal bar helps to maintain the width of the dental arch. The transpalatal bar / Nance is a metal bar attached to the tongue side of the upper first molar bands, and form-fitted along the roof of the mouth, and it may or may not have acrylic. In cases where it is appropriate to use this appliance, it will be part of the beginning phase of orthodontic treatment. Primarily, they are placed in patients who are in transitional dentition (not all adult teeth have erupted), to hold space in the arch for the permanent teeth to erupt. The transpalatal bar / Nance / lingual arch appliances are used in the upper and lower arches to maintain space. ![]() ![]() To get the best results, you should talk to a doctor.

High-carbon steel also starts out weak but can be converted to a strong, brittle steel through heat treating.Īlloying elements can be added to iron and carbon to produce steel with desirable combinations of mechanical properties for specific applications. Low-carbon steel, which has very little carbon, is weak and doesn’t respond well to heat treating. Steel made of just iron and carbon is called “carbon steel.” It is not considered an alloy steel. Scientists have given names to different geometric arrangements, such as “austenite,” “ferrite,” and “martensite.” The same steel alloy has different properties depending on how the atoms are arranged. Heat treating can also change the arrangement of the atoms. For example, larger grains slip past each other more easily, and this makes the steel softer than it would be with more small grains to resist movement better. Different grain sizes and arrangements react differently to stress. Heat treating can alter both the grain sizes and the geometric arrangement of the atoms in the steel. At a microscopic level, steel is made of small grains, which are groups of metal atoms arranged in crystals. Heat treating means raising the temperature of steel and cooling it in precise, controlled steps to change its internal structure. Strength: a material’s ability to be stressed without becoming permanently deformed.ĭuctility: a material's ability to become permanently deformed under stress before it breaks.Ī material’s combination of strength and ductility that allows it to absorb energy without breaking. Hardness: a material’s resistance to wear and scratching. ![]() Some common steel properties include the following: Instead of deforming elastically and then bouncing back when the stress is removed, hard steel will tend to break under high stress. For example, extremely hard steel will be strong, but also brittle. By mixing in alloying elements and subjecting the mixture to high heat to change its hardness, we can modify mechanical properties like hardness, strength, toughness, and ductility.Įven in the best circumstances, however, some of these properties involve tradeoffs. Without heat treating and without alloying elements, steel is too soft for use in the best hand tools. Steel is, by weight, mostly iron (often 90% or more) with small amounts of carbon (usually 0.1% to 2%) and sometimes alloying elements mixed in. Which one is better? When properly manufactured and heat treated, they are chemically almost identical and perform similarly. ![]() You can send us your inquiry for a quote.WHICH IS BETTER FOR HAND TOOLS? Chromium-Molybdenum or Chromium-Vanadium Steel?Ĭhromium-molybdenum (also called chrome molybdenum, chrome moly, or Cr-Mo) and chromium-vanadium (also called chrome vanadium or Cr-V) are names for two families of steel alloys used in hand tool manufacturing.

The first one is a specific object used in the PartDesign Workbench, intended to model a single contiguous solid by means of PartDesign Features. These elements can be used as references to attach sketches and primitive objects.ĭo not confuse the PartDesign Body with the Std Part. The Body provides an Origin object which includes local X, Y, and Z axes, and standard planes. It can contain sketches, datum objects, and PartDesign Features that help in building a single contiguous solid.
