The element's highly radioactive isotope caesium-137 comes in a powdered form that can be dispersed in air or water exposure to the substance can cause burns, radiation sickness or death, depending on. Because of this, she says, "it would be difficult to compare studies using X-rays to the research that was done ten years ago".įor nuclear regulators, the risk posed by caesium is clear. Lattice dynamics of caesium chloride has been worked out employing the shell model of Cowley et al, taking into account tho polarisabilities of both the. But other immune cells, known as myeloid cells, rebounded faster after the X-ray treatment ( B. W. Gibson et al.

It is extracted from the mineral form halite or evaporation of seawater. Her research has revealed that immune cells called B lymphocytes recovered more slowly in mice treated with an X-ray irradiator than in those exposed to caesium. Rock salt ( NaCl) is an ionic compound that occurs naturally as white crystals. Goodell, who has found subtle differences in how the mouse immune system responds to the two types of device, prefers Baylor's caesium irradiator. ![]() Researchers have used the caesium devices for decades, to study everything from immunotherapy to cancer treatment, and some fear that switching to X-ray irradiators will affect their results. Now the US National Nuclear Security Administration (NNSA) is working with scientists to investigate how - or whether - to replace caesium irradiators with less dangerous X-ray technology. The US government fears that the radioactive caesium could be stolen to make a 'dirty' bomb. Catalog Number 102039 Product Name Cesium chloride.

So, is this exhibit a retrospective of photographs of landscapes that you’ve taken over your whole career? I think it has had some influence over several generations of designers now, in landscape architecture. As a result it’s had a significant influence on designers in the last few decades, and the images are quite powerful in terms of what Dan Kiley did at the Miller Garden. There was a book done on the Miller Garden for which I did photographs called “The Miller Garden: Icon of Modernism.” These images were reproduced many times in professional journals, magazines, books, as well as the monograph of the garden itself. I read online that you’re interested in the generational influences that past landscapes have had on the present. It’s been a long career in planning, urban design, and landscape design. In recent years I’ve done more landscape design and the rehabilitation of historic landscapes, such as the rehabilitation of the landscape at the Lincoln Memorial and the Reflecting Pool here in Washington. Early on, I did mostly planning and urban design. I started working at Sasaki in 1978 as an urban designer and landscape designer. My first degree is in architecture, and my second degree is in landscape architecture. How long have you been a landscape architect? ![]() ![]() Prospect Park was a significant early park by Olmsted, but also influential in design terms. For example, the Miller Garden in Columbus, Indiana, was a very important design in the modern era. Either they were new project types, or they were just extremely influential as designs. Either they were a new project type, like Riverside, Illinois, the planned community, or Blue Ridge Parkway, or Mount Auburn cemetery, or the University of Virginia. The idea is that these are some of the most significant landscape designs in the country. And then, in the mid-'90s, I had an opportunity to do a book on my photography, so I took what I had and I supplemented it with sites that I had selected. It’s a hybrid process.Ĭan you tell me a little bit about the concept behind this exhibit?Įarly on I was asked to photograph certain designers’ work for an exhibition, and that was the work of Dan Kiley and Beatrix Farrand. The original, in most cases, is from a negative. So, what you’re actually seeing are digital prints. Once I got the print I liked, I would send it with an overlay of notes on what I did to manipulate the print to a master printer who would scan the negative, make adjustments to match my print, and send me a proof that was printed digitally. I would have the negatives processed and make a print in the darkroom that met my requirements for lightening, darkening and cropping. All of the landscapes that were done on film were with either the 4x5 view camera or the medium-format. The last two sites in the exhibit were done more recently with a digital camera. It uses roll film, but three frames of a 2-and-a-quarter-inch negative. I also used a panoramic camera, which is also medium-format. In more recent years I started using a medium format camera, with a Hasselblad 2-and-a-quarter-inch negative. Most of the photographs are with a 4x5 view camera. There’s a 4x5 view camera-this is an old-style camera and a kind of a technology that originated in the late 19 th century, and architectural photographers used it until being supplanted by digital cameras. The cameras are actually on display in the exhibit. We chatted with Ward about his transition from film to digital photography, and about some of his favorite landscapes.Ĭan you tell me about the cameras that you used to take these photos? Luminous Landscapes, which will run through September, showcases the history, evolution, and sheer beauty of American landscape design, as well as Ward’s own keen eye and skill with a camera. Ward’s photography work is currently being featured in a retrospective of sorts at Washington, D.C.’s National Building Museum. He took his first photograph in 1978, the same year that he started working at the Watertown, Massachusetts architecture firm Sasaki Associates, using a large-format view camera with a tripod to capture an image of Cambridge’s Mount Auburn Cemetery. Landscape architect Alan Ward, FASLA, has channeled his love of photography into a second career spanning nearly 40 years. ![]() Overwhelm opponents with a flurry of force in a series of intense and bloody battles while learning the precision and skill necessary to become a true master of the sword.” Renowned for ruthless strikes that can instantly change the tide of battle, sword practitioners of the Chinese martial arts gracefully change pace as they shift between offensive and defensive maneuvers.

Note the mileage and consider if the timing chain needs to be changed.Basically, you will be tearing the front side of the engine down to get the front cover off to expose the timing components.ĭisconnect the battery. This is also something to keep in mind if you’re shopping for pre-owned vehicles. While replacing a worn timing chain isn’t easy nor cheap, it’s still less expensive than replacing an engine due to a broken timing chain. Is It Worth Fixing A Timing Chain?Īssuming you want to keep driving your vehicle, then yes. As such, it’s a good idea to have a timing chain replaced between 80,000-120,000 miles. That said, wear and tear will happen - faster in cars with high mileage. Timing chains are highly durable and are designed to last your vehicle’s lifetime. If these parts don’t work correctly, your timing chain can come loose and free to slap against other engine components. The timing chain is lubricated by engine oil, so regular oil changes promote its longevity.Ī defective chain tensioner or chain guide can also damage the timing chain. However, accelerated wear can happen when the vehicle doesn’t stick to scheduled oil changes. Timing belts are rubber, located outside the engine, are quieter and cheaper to manufacture but require more frequent replacement than a timing chain.Timing chains are metal, located inside the engine (so they can be lubricated with engine oil), and generally last longer, saving cost in the long run.Timing chains and timing belts have the same function - they connect the engine’s camshaft and crankshafts. ![]() Is A Timing Chain The Same As A Timing Belt? And it’s important to note that some cars use a timing belt instead of a timing chain. The timing chain may also drive components like the water pump and balance shaft in certain engines. This allows your intake and exhaust valves (operated by the camshaft) to be timed correctly with the pistons (operated by the crankshaft) - resulting in proper engine combustion. The timing chain synchronizes your vehicle’s crankshaft and camshaft(s). Here are answers to some timing chain questions: 1. Small metal pieces in your engine oil when drained, or found in the oil filter, could mean your timing chain needs a replacement. Metal shavings in your oil: Tiny metal bits can shear off a worn timing chain. Your engine may stutter, feel sluggish, experience misfires, and hesitate on acceleration.Įngine won’t run: If your timing chain is very far gone, your engine may not run as the timing is completely off. Valves don’t open and close at the correct time, resulting in incomplete combustion. Poor engine performance: A stretched timing chain will cause the camshaft and crankshaft to be out of sync. Damage to related components like chain guides or a chain tensioner will also produce noises like whining or buzzing. It’ll trigger your dashboard check engine light and likely store a timing-related trouble code, like P0011 or P0012 - depending on which timing component prompted the warning.Įngine noises: A loose or damaged timing chain often makes a rattling or whirring sound. What Are The Symptoms Of A Defective Timing Chain?Ī faulty timing chain will cause your vehicle to exhibit one or more symptoms.Īn illuminated check engine light: If your timing isn’t running right, your engine computer will detect this problem at some point. ![]() His roundups of new features in Windows 10 updates have been called "the most detailed, useful Windows version previews of anyone on the web" and covered by prominent Windows journalists like Paul Thurrott and Mary Jo Foley on TWiT's Windows Weekly.
