Incisal Endodontics Access vs Traditional Palatal Access to Negotiate Simulated Obliterated Canals Using Guided Endodontic Techniques
… treatment in teeth with pulp canal obliteration (PCO) is challenging. Guided Endodontic Access (GEA) combines information from a cone-beam computed tomography (CBCT) scan with an intra-oral scan to create a stent that can be used as a guide to treat teeth with PCO. GEA stents designed with …

Defect equilibria and electrode kinetics in Prx̳Ce1̳-̳x̳O2̳-̳[̳d̳e̳l̳t̳a̳]̳ mixed conducting thin films : an in-situ optical and electrochemical investigation
… applied to the Prx̳Ce1̳-̳x̳O2̳-̳[̳d̳e̳l̳t̳a̳]̳, (PCO) model thin film system. PCO shows mixed ionic and electronic conducting (MIEC) characteristics at relatively high pO2 regimes (e.g. air), which is beneficial for solid oxide fuel cells (SOFCs) cathode performance. The Pr impurity levels in PCO …

The Effects of High Environmental Temperature Induced Acid-Base Disturbance on The Utilization of Calcium by The Domestic Hen
… on respiratory rate, blood pH, blood PCO(,2) and blood HCO(,3)('-) concentration was investigated in SCWL hens. Within one hour after initiation of heat challenge, respiratory rate was significantly (P < .01) elevated which led to blood alkalosis from a reduction (P < .01) in blood …

The Effects Of Dissolved Oxygen Content Of Water On Blood Ph, Pco4, Po4 And Rocking Activity For Cryptobranchus Alleganiensis
… O₂ content of water on in vivo blood pH, pCO₂, pO₂ and rocking activity were measured for Cryptobranchus alleganiensis. Measurements were taken at 100%, 75%, 50%, 25%, 20%, 15%, 10% and 0% saturation levels while temperature was held constant at 12°C. Results indicate that reduction of …

Assessing the welfare of adult Atlantic salmon, Salmo salar during commercial live-haul transport
… demonstrated that the partial pressure of CO₂ (Pco₂) could accumulate to potentially deleterious levels (>10 torr) in 20-158 min depending on fish stress levels and loading densities. These data may be useful in estimating transport lengths possible under Pco₂ thresholds, which are presently …

Chemomechanics of non-stoichiometric oxide films for energy conversion
… films of the model material PrxCe1-xO2-[delta] (PCO) that is a fluorite-structured oxide relevant to SOFC applications. PCO is an excellent model system because of its well-established defect chemistry model and known thermal and chemical expansion coefficients. The thesis begins by first …

The effects of added fat on acid-base status in exercising horses
… Blood was analyzed for pH, hemoglobin, and pCO₂, and base excess and plasma bicarbonate levels were calculated using nomogram equations. Plasma samples were analyzed for albumin at each step, and for sodium, potassium, chloride, and lactate at rest and exhaustion only. The plasma SID was …
