A theoretical model of the process has been developed, amenable to computer handling, that should allow calculation of the rate constants associated with the transfer through and release of radioactive material from a filter system by this process. It appears that this phenomenon has not been observed in previous experiments with alpha-active aerosols because more » the tests did not continue for a sufficiently long time. ![]() Dependence on the air flow velocity is slight. ![]() The amount penetrating a series of filters depends on the total amount of activity in the source material, its specific activity, and the length of time of air flow. Oxide dust, nitrate salt, and plated metal all seem to generate the recoil particles effectively. The process shows only a small dependence on the physical form of the source material. Results with controlled air-flow through filters in series are consistent with the picture of small particles dislodged from the ''massive'' surface of an alpha-active material, and then repeatedly dislodged from positions on the filter fibers, by the alpha recoils. Filter retention efficiencies drastically lower than the 99.97 percent quoted for ordinary particulate matter have been observed with /sup 212/Pb, /sup 253/Es, and /sup 238/Pu sources, indicating that the phenomenon is common to all of these and probably to all alpha-emitting materials of appropriate half-life. Tests at Oak Ridge National Laboratory confirmed that alpha-emitting particulate matter does penetrate high-efficiency filter medium, identical to that used in HEPA filters, much more effectively than do non-radioactive or beta-gamma active aerosols. ![]() ![]() ![]() If a font’s letter “A” has serifs, we expect its B to have serifs too, and so on from there. ![]() Futura is a clean typeface with even kerning ConsistencyĬonsistency means all the letters, numbers and any other characters used maintain the same look.

An all new black carbon fiber cosmetic creates the appearance of a thinner topline for a sleeker and more compact look at address.ĬOBRA’s patented PWRSHELL technology continues to offer increased speed and higher launch even on stronger lofted irons. In addition, the irons feature a unique Carbon Fiber Topline that saves 2g to lower the CG and improve launch and spin characteristics. Radial Weighting is a critical component of the design that allows the RADSPEED irons to maintain high launch and maximum carry distance, despite having a stronger loft. This weighting system delivers an iron set that is truly custom built for the golfer. During custom builds this weight may be adjusted +/- 6g utilizing weights ranging from 4g to 16g in increments of 2g to dial in proper swing weights when customizing length or shafts. The 10g screw is a nominal weight used by COBRA to guarantee perfect head weights for improved builds. ![]() 10g, in the form of a screw-in weight, is positioned in the toe and 3g of mass, is positioned in the heel to create the best combination of low CG, and high MOI for the fast ball speed and high launch. COBRA engineers discovered that by positioning more mass low on the heel and toe (the two furthest points from the CG while remaining low in the head), they could lower the CG while dramatically improving the stability of the clubhead. With a name inspired by its key technology, Radial Weighting, the design of these irons is aimed at maximizing performance through the strategic placement of weight relative to the Center of Gravity (CG) to optimize speed and forgiveness. The medallion reduces weight to lower the CG and damp harsh vibrations at impact delivering a soft feel and great response to the golfer. Upon closer review, golfers may notice the detailed lattice structure provides a window into the cavity and through the medallion. This first ever 3D printed nylon medallion utilizes an intricate lattice structure to save weight and fine-tune feel.

The microscopist Walter McCrone found, based on his examination of samples taken in 1978 from the surface of the shroud using adhesive tape, that the image on the shroud had been painted with a dilute solution of red ochre pigment in a gelatin medium. : 233 Ownership of the shroud passed from the House of Savoy to the Catholic Church after the death of former king Umberto II in 1983. : 191 Since 1683, it has been kept in the Chapel of the Holy Shroud, which was designed for that purpose by architect Guarino Guarini and which is connected to both the royal palace and the Turin Cathedral. : 166 In 1578, the Savoys moved the shroud to their new capital in Turin, where it has remained ever since. : 90–96 It was acquired by the House of Savoy in 1453 and later deposited in a chapel in Chambéry, : 141–142, 153–154 where it was damaged by fire in 1532. : 80–81 The shroud was denounced as a forgery by the bishop of Troyes in 1389. The documented history of the shroud dates back to 1354, when it was exhibited in the new collegiate church of Lirey, a village in north-central France. The shroud's authenticity as a holy relic has been disputed even within the Catholic Church (see below), and radiocarbon dating has shown it to be a medieval artifact. This negative image is associated with a popular Catholic devotion to the Holy Face of Jesus. ![]() The human image on the shroud can be discerned more clearly in a black and white photographic negative than in its natural sepia color, an effect discovered in 1898 by Secondo Pia, who produced the first photographs of the shroud. It has been venerated for centuries, especially by members of the Catholic Church, as the actual burial shroud used to wrap the body of Jesus of Nazareth after his crucifixion, and upon which Jesus's bodily image is miraculously imprinted.

It offers illumination, but with more LEDs so things are more evenly distributed. This model has a 7-inch display - so, larger than all the other Kindle devices - and incorporates all the top features. But in the end, a dull story, plodding pace and uncertain spiritual origins might keep the Vizati cube from getting too comfortable on your desktop or smartphone.Bigger and better, the Kindle Oasis is designed to be the ultimate reading device. Finally finishing that stubborn stage is always a satisfying feeling, and the beautiful backgrounds and music are easy on the eyes and ears. By adding more stones to penalize the player for taking too long, the game actually becomes easier rather than harder.Īnd in a market flooded with free flash games and $2.99 iphone games, it's hard to stand out in the pack. While playing arcade does introduce a countdown that adds more stones every 30 seconds, it does away with the move constrictions, effectively turning your patient tweaking of the cube into spamming the shake button. ![]() The game's arcade mode finally unlocks after completing the 50 stages and after the disappointing story, I was hoping this would be Vizati's saving grace. The difficulty seems to plateau throughout the first and second act, and a lack of time constraints give the game a more plodding, albeit methodical, rhythm. However, for me it eventually came down to the game's lack of pace that kept it from becoming a Bejeweled-like addiction. Many levels go by with no advance in the story and when it does advance it's littered with bad jokes and unlikeable characters.Īt one point, what appears to be a witch-doctor tries to interact with the cube and it never becomes clear what the Vizati stone is or where it came from, though some sort of magic or spiritual origin is implied. Dialogue is stilted and silly, and the plot to discover the origins of the Vizati is incoherent. Unlike the impressionistic backgrounds, character models are bland and poorly animated. But the cube is neither drawn to scale to the world, nor do the characters ever interact with the object. Story Mode opens as Peter and Julie stumble upon the Vizati cube while out for a walk. Unfortunately, it's Vizati's attempt at a narrative that ultimately undermines the experience and remains a constant reminder of its indie roots. The minimalist music and sounds also create an atmosphere reminiscent of 2008's platformer/puzzler Braid or even the award-winning Limbo.

The difficulty quickly ratchets up about halfway through, creating more than a few headaches. Even the final levels can be solved in less than five actions, but that doesn't mean Vizati is easy. Sometimes a quick shake will initiate a chain reaction other times turning the cube upside down will suddenly make a complex puzzle relatively simple. You can do this using your mouse or fingers if you're using a touch screen, but I found the mouse controls imprecise and stuck mostly to the keyboard when playing. ![]() Vizati asks you to manipulate a magical 2D "cube" to group the coloured stones within in the least amount of moves by either rotating, flipping or shaking the puzzle. Vizati employs the match-three-colors mechanic of its PopCap competition, but adds a twist. Unfortunately, a few key variables were left out of the equation, keeping Vizati from joining the mainstream's more popular puzzling addictions. Clearly the small team put a lot of sweat and tears into making a solid puzzle game with beautiful water color backgrounds and music to match. ![]() Vizati is a work of indie development love.
