Research And Education

Abstract The study was located on bentgrass range 1 north at the Ohio State Turfgrass Research and Education Center, Columbus, OH. Treatments were applied on 19 Aug to plots 4 X 6 ft arranged in a RCB, replicated 4 times. Liquid treatments were applied using a CO2 sprayer calibrated to deliver 2.0 gal/1000ft2. No immediate posttreatment irrigation was applied. The 100% creeping bentgrass range was mowed at 0.5 inch, had no thatch and was irrigated daily with 0.25 inch of water between (05:00 and 06:00). On 19 Aug, one 8-inch stainless steel cylinder was driven into the turf, about 2 hr after the last spraying to allow for complete drying of all treatments. Each cylinder was infested with eight 3rd- and 4th-instar BCW (0.375 to 0.5 inch) and covered with nylon screen. On 22 Aug (3 DAT) the covers were removed and each cylinder was flooded with a soapy water mix (15 ml Joy dishwashing detergent in 1.0 gal water) to flush out any live BCW.

The City

On September 13, 1987, two metal and paper scavengers of the city of Goiania (pop. 1,000,000), in the central Brazilian state of Goias (pop. 13,000,000) entered an abandoned clinic in search of scrap metal. They discovered a 400-kilograrn machine that had been used to treat cancer patients with controlled doses of radiation. They dismantled the device and extracted a stainless steel cylinder; then they took the cylinder to a junkyard, broke it open with a sledge hammer, and removed a one-cubic-inch platinum capsule. Subsequently they sawed open the capsule, revealing approximately 100 grams of luminescent material, which was described by witnesses as "carnival glitter."

Polished Stainless Steel

Abstract The work is aimed at studying the effect of galvanic nickel coating of a stainless steel cylinder on the quenching. In order to compare the results, the polished stainless steel cylinder was used as a sample. In addition, the influence of the formation of an oxide layer on the cooling process was studied. The experiments were carried out in water and ethanol with different subcoolings. The oxidized porous nickel coating led to increasing of the transition temperature from stable film boiling to intensive boiling regime. It was especially noticeable for cooling in water at high subcooling due to the higher cooling intensity caused by vapour layer thinning.

As a kind of corrosion resistant material, stainless steel is widely used in petroleum, chemical, pharmaceutical. Stress corrosion cracking is a main reason that why the stainless steel became disabled. Therefore, it is very necessary to research and study the stress corrosion cracking of stainless steel .The failure analysis to the sample is conducted aiming at the stress corrosion of the stainless steel piston cylinder in a factory. The analysis includes macro analysis, metallographic observation, scanning electron microscopy analysis and XRD analysis. The results of the study show that it is nonmetallic inclusion on the grain boundary, the chloridion in the industrial circulating water and the rough columnar austenitic grains in the organization of the samples that lead to the stress corrosion cracking of the piston cylinder.
