Search For The Next "Silver Bullet": A Review Of Literature, V. A. Black, G. Njewel
Journal of the Arkansas Academy of Science
We present a review on the application of silver containing compounds that have been incorporated in the surfaces of a large variety of medical devices including vascular, urinary, and peritoneal catheters, endotracheal tubes, sutures, and fracture fixation devices, as well as other materials such as plastics in kitchen appliances and fabrics. We found renewed and rising interest in silver-containing materials due to their antimicrobial, including antiviral and antifungal, properties, their good toxicology and environmental record. Silver-containing compounds could be used against bacterial strains that are known to be resistant to antibiotics. More research is necessary to determine safe levels and …

Effects Of Welding Electropolished Stainless Steel As Used In Ultra-Pure Fluid Delivery Systems For The Semiconductor And Pharmaceutical Industries, Steve Trigwell, Guna Selvaduray
Journal of the Arkansas Academy of Science
In the semiconductor and pharmaceutical industries, care is taken to prevent any contribution to product contamination or corrosion from the fluid delivery systems. Electropolished 316L stainless steel has become the industry standard due to its superior corrosion resistance. However, welding of the tubing often leads to discoloration in the heat affected zone (HAZ) which can lead to corrosion. Electropolished specimens from various lots of 316L stainless steel tubing were welded under identical parameters, but with varying concentrations of oxygen leaked into the argon purge gas during the welding, simulating on-site welding conditions. Various levels of discoloration were observed in the …

Journal of the Arkansas Academy of Science
The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the …
