Contributory Negligence, Comparative Negligence, and Stare Decisis in North Carolina

Part I of this article examines the contributory negligence doctrine and its history in the United States and North Carolina. Part II describes some of the criticism levelled at the contributory negligence doctrine. Part III examines the comparative negligence doctrine, including a-description of the types of comparative negligence systems, a history of the doctrine, and a look at the history of comparative negligence bills in the North Carolina General Assembly, concentrating on the several comparative negligence bills introduced in the 1980s and one of the principal arguments made against the bills. Part IV discusses North Carolina\u27s stare decisis jurisprudence and judicial deference to the legislative branch in relation to the common law of North Carolina and the contributory negligence doctrine

Fiber-optic push-pull sensor systems

Fiber-optic push-pull sensors are those which exploit the intrinsically differential nature of an interferometer with concommitant benefits in common-mode rejection of undesired effects. Several fiber-optic accelerometer and hydrophone designs are described. Additionally, the recent development at the Naval Postgraduate School of a passive low-cost interferometric signal demodulator permits the development of economical fiber-optic sensor systems

Platinized tin oxide catalysts for CO2 lasers: Effects of pretreatment

Platinized tin oxide surfaces used for low-temperature CO oxidation in CO2 lasers have been characterized before and after reduction in CO at 125 and 250 C using ion scattering spectroscopy (ISS) and X ray photoelectron spectroscopy (XPS). XPS indicates that the Pt is present initially as PtO2. Reduction at 125 C converts the PtO2 to Pt(OH)2 while reduction at 250 C converts the PtO2 to metallic Pt. ISS shows that the Pt in the outermost atomic layer of the catalyst is mostly covered by substrate species during the 250 C reduction. Both the ISS and XPS results are consistent with Pt/Sn alloy formation. The surface dehydration and migration of substrate species over surface Pt and Sn appear to explain why a CO pretreatment at 250 C produces inferior CO oxidation activities compared to a 125 C pretreatment

Effect of pretreatment on a platinized tin oxide catalyst used for low-temperature CO-oxidation

A commercial platinized tin oxide catalyst used for low-temperature CO oxidation has been characterized using ion scattering spectroscopy (ISS), Auger electron spectroscopy (AES) and Electron Spectroscopy for Chemical Analysis (ESCA) before and after reduction in 40 Torr of CO for 1 hour at various temperatures from 75 to 175 C. The reduction results in loss of surface oxygen, formation of metallic tin, conversion of platinum oxides to Pt-O-Sn and Pt(OH)2 and a small amount of metallic Pt which alloys with the tin. These results should be useful in understanding how the pretreatment temperature affects the catalytic activity of platinized tin oxide toward CO oxidation

Influence of Harvest Processes on Pork Loin and Ham Quality

The influence of the timing and duration of slaughter processes on pork quality was evaluated.The results demonstrate that reducing the time to evisceration is less important than reducing the time to the initiation of carcass chilling. A shortened interval between stunning and cooling can be accomplished by decreasing time allowed for blood removal (dwell time) and scalding.A dwell time of 3 min should allow harvest facilities to maximize profits from blood yields and allow carcasses to enter the scalder at an earlier time postmortem.Lengthening the duration of scalding may result in a more rapid postmortem pH decline. It is recommended that each individual processing facility monitor scald times to determine the appropriate length of time needed to maximize hair removal and minimize time spent on the slaughter floor
