Based on the technology developed for using PVA fiber as a replacement for asbestos in cement products, Kuraray has been developing thick fibers for reinforcing concrete (42). Super-thick fibers with a thickness of 39 tex (350 den) (200 p.m in diameter) to 444 tex (4000 den) (660 p.m in diameter) are now available the 39 tex material is used for reinforcing various mortar-based cement products and the 444 tex material for reinforcing concrete in civil engineering works such as tuimels, roads, harbors, and bays.  [c.342]

The majority of refineries operated by petroleum companies in different parts of the world to make local products, such as gasoline and burner fuels, also produce jet fuels. Even a small refinery with simple equipment can make suitable jet fuel if it has access to the right cmde. However, the principal supply of both civil and military jet fuels is produced in large refineries. Many are located near major cities and airports and are frequentiy connected by pipeline directiy to the airport. Modem airports have extensive storage and handling faciUties operated by local authorities, petroleum companies or consortia, or the airlines themselves.  [c.417]

This early enlightenment came to an end in the chaos of the Thiny Years War and the English Civil War, but the work of these men was revived later in the seventeenth centuiy as growing national economies and populations required ever greater resources. The search for better heating apparatuses became critical as a bitter cold wave swept over Europe in the early eighteenth centuiy. Technologists responded to the need, and in 1713 Nicholas Gauger published La Mechanique de Feu, which described a number of methods to improve heating systems. By 1720 Paris was suddenly warm, and newspapers in both London and Paris advertised firms that could heat rooms of any size without the least suffocation. Warmth came with a price, however, and the streets of Paris were soon cluttered with thousands of carts laden with wood and sawyers plying their trade.  [c.346]

Well cementing materials vary from basic Portland cement used in civil engineering construction of all types, to highly sophisticated special-purpose resin-based or latex cements. The purpose of all of these cementing materials is to provide the well driller with a fluid state slurry of cement, water and additives that can be pumped to specific locations within the well. Once the slurry has reached its intended location in the well and a setup time has elapsed, the slurry material can become a nearly impermeable, durable solid material capable of bonding to rock and steel casing.  [c.1177]

The most widely used cements for well cementing are the Portland-type cements. The civil engineering construction industry uses Portland cement and water slurries in conjunction with clean rock aggregate to form concrete. The composite material formed by the addition of rock aggregate forms a solid material that has a compressive strength that is significantly higher than the solid formed by the solidified cement and water slurry alone. The rock of the aggregate usually has a very high compressive strength (of the order of 5,000 to  [c.1177]

The databases of CAS are accessible through two major tools - STN software and SciFinder. STN Information was formed by the collaboration of CAS with FIZ Karlsruhe, Germany and the Japan Information Center for Science and Technology (jlCST) in order to meet customer needs more effectively for access to the rapidly growing resources of scientific and technical information. For a long time search ing in CA databases had to be performed in alphanumeric form with the Messen gcr language. Because of the complexity of the task searching was mostly per formed by experts. Then, the STN Express software was introduced for searching in CAS files. Next, STN Easy, a browser-based interface for novice users, was devel oped along with STN on the Web, which provided the STN command line capabil itics within a web browser.  [c.242]

The transient component depends not only on G, cake height, and cake properties, but also on dewatering time, which ties to sohds throughput for a continuous centrifuge and cycle time for batch centrifuge. if the throughput is too high or the dewatering cycle is too short, the hquid saturation can be high and becomes hmiting. Given that time is not the hmiting facdor, dewatering of the liquid lens at particle contact points requires a much higher G-force. The residual saturation depends on the G-force to the capillary force, as measured by N, the maximum of which is about 7.5%, which is quite significant. If the cake is not disturbed (scrolled and tumbled) during conveyance and dewatering, hquid can be further trapped in fine capillaries due to liquid rise, the amount of which is a function of which weighs the G-force to the capillaiy force. This amount of hquid saturation is usually smaller as compared to capillary force associated with hquid-lens (also known as pendular) saturation. Lastly, liquid can be trapped by chemical force at the particle surface or physical capillaiy or interfacial force in the pores within the particles. Because the required desaturating force is extremely high, this portion of moisture cannot be removed by mechanical centrifugation. Fortunately, for most apphcations it is a small percentage, if it exists.  [c.1741]

The literature on this subject is so large that it cannot be encompassed in a brief review. N UR CG/CR-1030(1981) is a bibliographical survey of 123 references Covello, 1981 lists 148 rcler-ences. Since no risk should be tolerated if it has no benefits, most of the papers address the question "How safe is safe enough," by comparisons with acceptable risks. (In many cases these "acceptable" risks are really "tolerated" risks in that the cost of reduction does not seem to be warranted.)  [c.12]

Although open fireplaces were still common in houses for both heating and cooking, the stove came into widespread use during the nineteenth centuiy. Part of this was due to the increasing number of manufacturers who could produce a quality product at low cost, but probably more important was the disappearance of wood as a domestic fuel over the course of that century, in America, just as it had in England three centuries earlier. This had probably been inevitable. Within two decades of the day the first English landed in Boston, the surrounding fuel supply had been burned up. One of the reasons why Massachusetts acquired Maine in 1677 was to tap its seemingly inexhaustible forests. Even Haiward University in 1800 had its own ship to bring fuel-wood for its students and faculty from its land in Maine. As Americans moved westward across the continent, they were sure that the forests would last forever. In fact they did not last long at all, and only the discovciy of coal in large quantities in Wyoming made it possible to build and operate the transcontinental railroad after the American Civil War. One of the most telling stories of this is Laura Ingall Wilder s The Long Winter, in which she describes living in a small town in South Dakota during the winter of 1880-1881. There were no trees (her six-year-old sister had never seen one), and the community was entirely dependent on coal delivered by railroad. During a particularly severe blizzard the tracks were blocked for several weeks, and Laura and her family burned straw and furniture to maintain a minimum amount of heat.  [c.347]

Software is also the biggest potential limiting factor of a program. Even though all vendors use some form of formal computer language, i.e. FORTRAN, Cobol, basic, etc., they are normally not interchangeable with other programs. The apparently simple task of having one computer program communicate with another can often be impossible. This lack of compatibility between various computer programs prohibits transferring a predictive maintenance database from one vendor s system into a system manufactured by another vendor. The result is that once a predictive maintenance program is started, a plant cannot change to another system without losing the data already developed in the initial program.  [c.807]
