The efficacy of ultraviolet C (UVC) light (100-280 nm) in the decontamination of three hospital-related surfaces, namely, unpainted/painted aluminum (bed railings), stainless steel (operating tables), and scrubs (laboratory coats), was investigated. Acinetobacter baumannii cells were inoculated (10(5) or 10(3) cells) on small coupons and dried overnight in a class II biosafety cabinet. Drying r...

Hydrogen Induced Cracking (HIC) and Stress Oriented Hydrogen Induced Cracking (SOHIC) tests were conducted on a conventional ASTM A516-70 pressure vessel steel exposed to H2Scontaining diglycolamine (DGA) gas-sweetening environments. Baseline HIC and SOHIC tests were conducted in NACE TM0284-96 solution A. For the SOHIC tests, four-point double beam specimens were stressed to 60%, 80% or 100 % ...

effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. lungmuir, frumkin and flory-huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

The oldest of all the shaft specifications is flex. Once the production problems had been overcome which enabled steel shafts to become a reality, early steel shaft manufacturers began to experiment with producing shafts, which possessed different amounts of resistance to bending. Through the 70 years of shaft design that have followed the introduction of the steel shaft, companies have produce...

The structural and mechanical response of metals is intimately connected to phase transformations. For instance, the product of a phase transformation (martensite) is responsible for the extraordinary range of strength and toughness of steel, making it a versatile and important structural material. Although abundant in metals and alloys, the discovery of new phase transformations is not current...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
