The chemical behavior of polonium was described many years ago by Haissinsky 18, 19 and others, later by Moyer, 33 and in the Russian literature by Moroz and Parfenov. Some have postulated that the alpha-particle radiation from polonium, volatilized from smoking tobacco, plays an important role in the genesis of lung cancer in smokers. Airborne radon decays into polonium isotopes that can be deposited on terrain and vegetation, for example, on tobacco leaves. Polonium occurs naturally in the environment. However, polonium is difficult to contain, and there have been instances of contamination, not only from static-eliminator bars but from solutions left in the open, because of polonium's marked tendency to ''creep." The high specific ionization around such devices is effective in reducing static electricity buildup. During the Manhattan Project days of World War II, large quantities of 210 Po were produced at a plant in Dayton, Ohio, and protection of workers and the environment was needed.Ģ10Po has found wide application in static-eliminator devices, for example, in paper and textile plants. In fact, 210Po was the alpha-particle source in the neutron-producing initiators of at least the first generation of atomic weapons. Many large alpha-particle sources were prepared before plutonium was available in sufficient quantities to supplant polonium for this, application. ![]() ![]() Polonium has been used extensively as an alpha-particle source for the production of neutrons by interaction with beryllium. These properties led to its use in much experimental work that required an alpha-particle, source with useful energy and a convenient half-life. There are other reasons for interest in polonium of primary interest is primarily the isotope 210Po, which has a half-life of about 138 days and decays to a stable lead isotope ( 206Pb) by almost pure alpha-particle emission. One reason for interest in the alpha particles from polonium is their existence as radon daughters indeed, with respect to important radiation dose, the radon problem is due largely to polonium.

When using the rule of thirds, you should place your subject at one of these intersections. The four points where the lines intersect are considered to be power points. It’s a composition guideline entailing dividing the frame into nine equal portions. On the other hand, when shooting portraits, you will want to fill the frame with your subject, so there is no need to crop the photo later. In simpler terms, when shooting landscapes, you will want to leave some extra space in the frame so that you can crop the photo later on if necessary. ![]() Kate Sports Foggy light Backdrop for Photography However, portrait photos are typically shot in a vertical orientation, which means they will lose some vital information if they are cropped into a horizontal orientation. ![]() Landscape photos are usually shot in the horizontal orientation, which means they can be cropped into a vertical orientation without losing any important details. You will want to use a telephoto lens to capture all the details. On the other hand, when shooting portraits, the focus is on the subject itself. This means you will want to use a wide-angle lens to fit everything into the frame. When shooting landscapes, the focus is on the scene as a whole. However, a few key factors can help you make the best choice for your particular photo. Which one to Choose, Landscape or Portrait?Ĭhoosing between a portrait vs landscape orientation for your photos can be daunting. This is because you have more room to work within a landscape photo. You can be further away from your subject when shooting in landscape format and still get a great shot. If you're too far away, your subject will look small and lost in the photo. This is because you need to fill the frame with your subject. You're usually pretty close to your subject when shooting in portrait format. You might have to take a step back and look at the photo to figure out what's happening. It's easy to tell what the subject is and what's going on in the photo.Ī portrait format can sometimes be slightly confusing because there's so much going on in the photo. When you're shooting in landscape, the context of your photo is usually pretty clear and straightforward. In this case, you'll want to consider using a shallow depth of field so that both the foreground and background are in sharp focus. Kate Brown Abstract Old Master Backdrop for PhotographyĪ landscape format can have a background that's just as interesting as the subject itself. You can blur out the background to make it less distracting or accentuate it for effect. With a portrait format, the background usually becomes more of a supporting role. A portrait format focuses on the subject and isolates it from the background. Portrait photos tend to be more intimate because there's less space around the subject. It can also help to create a sense of scale and depth. You can use that extra space to show the setting or environment of your subject. In general, landscape photos have more space. So, you'll need to turn the camera to the side and shoot horizontally. This type of orientation is often used for shots that need to capture a large area, such as a sweeping landscape. Landscape orientation is just the opposite - it's when the photograph is wider than it is tall. This type of orientation is typically used for close-up shots of people or objects. Portrait orientation is when the photograph is taller than it is wide. Main Differences Between Portrait vs Landscape ![]() In this article, we'll be discussing the main differences between landscape vs portrait orientation, as well as how you can decide which one is right for your needs. Both of these terms refer to the way that the photograph is oriented on the page or screen. When it comes to photographs, there are two different orientations that you can choose from: portrait or landscape. ![]() ![]() Meetings such as these usually include lectures by health professionals as well as demonstrations and master classes by artists. This has become an annual conference and is perhaps the most important in the field. In 1983 the first Medical Problems of Musicians and Dancers symposium was held, in conjunction with the Aspen Music Festival, in Aspen, Colorado. ![]() Since then, the field of performing arts medicine has advanced rapidly, with conferences, publications, clinics and associations. These were virtually the first well-known musicians to admit to physical problems, so the publicity generated by their cases brought forth a large, previously unknown group of injured artists. In 1981 a New York Times article described the hand problems suffered by pianists Gary Graffman and Leon Fleisher, and their treatment at Massachusetts General Hospital. ![]() While injured performers and the health professionals serving them began to cooperate more closely, the general public was unaware of these developments. This has become an annual conference, with proceedings appearing in the Journal of Voice. Also in 1972 the first Care of the Professional Voice Symposium was organized by the Voice Foundation. The conference focused on music and led to the publication of Music and the Brain: Studies in the Neurology of Music, by MacDonald Critchley and R.A. One of the catalysts for the development of performing arts medicine as a cross-disciplinary field was the Danube Symposium on Neurology, held in Vienna in 1972. There was a parallel growth of awareness among dancers. The musical literature also began to carry short items and letters. After World War II, the medical literature began to feature case reports of injured artists. This was the first textbook to bring together all the current knowledge on performing arts medicine. In 1932 the English translation of Kurt Singer’s Diseases of the Music Profession: A Systematic Presentation of Their Causes, Symptoms and Methods of Treatment appeared. Sporadic interest in arts medicine continued through the eighteenth and nineteenth centuries. While interest in the physiology of music making dates back to antiquity, the first real summary of the occupational diseases of performing artists is Bernardino Ramazzini’s 1713 treatise Diseases of Workers. ![]() ![]() ![]() Production so be careful of environment differences if you are working on Windows and deploying to Linux.

![]() ![]() The American College of Obstetricians and Gynecologists (ACOG) states that pregnant women limit the amount of caffeine they take to 200 mg per day. However, other studies have linked higher amounts of caffeine consumption to increased risks of miscarriage and low birth weight. Some studies have shown that moderate amounts of caffeine (200 mg or less) are not harmful to the developing fetus. So what does this mean for pregnant women? Well, the jury is still out on how much caffeine is safe to consume during pregnancy. But did you know that it can also be found in chocolate, some over-the-counter medications, and even ice cream? Caffeine is a stimulant that can have both positive and negative effects on our bodies depending on how much we consume. We all know that caffeine can be found in many popular drinks such as coffee, tea, and soda. Second, even though decaf tea is safe for pregnant women, it’s still important to limit yourself to no more than two cups per day.
