Performance Measurement Using IRI and Collision Rates in the Province of Alberta
… of roads. The International Roughness Index (IRI) is a widely used performance measure in Canada and Internationally. It is calculated from direct profile measurement of the pavement wheel paths and translated into metres per kilometre. In 1999, the Province of Alberta tied its performance …

Ray Tracing Analysis for the mid-latitude SuperDARN HF radar at Blackstone incorporating the IRI-2007 model
… tracing code was modified, to incorporate the IRI-2007 model for electron density. This ray tracing code was used to simulate the ground scatter pattern observed at Blackstone in the year 2009. Simulations were compared with the observed ground scatter to assess our understanding of the …

The Effect of Organic Resins on Ice Recrystallization
… properties of ice recrystallization inhibitors (IRIs), which reduce the growth rate of ice crystals and lead to a decrease in cellular damage due to the aforementioned factors. In this thesis, the IRI activity of Wang and PEGA resins was evaluated, finding no IRI activity when compared with 2FA, …

α-Lipoic Acid Attenuates Ischemia Reperfusion Injury of the Rat Liver
107 Ischemia reperfusion injury (IRI) represents a major clinical problem in liver transplantation and resection. Main pathophysiological events during this injury comprise depletion of ATP, Kupffer cell activation with subsequent formation of reactive oxygen species and inflammatory response. …

A Discrete Roughness Index for Longitudinal Road Profiles
… products. The International Roughness Index (IRI), a standardized means of assessing longitudinal road roughness, quantifies roughness based on the average suspension travel for a particular vehicle at a prescribed speed. The Discrete Roughness Index (DRI) developed in this work address …

Detailed Inventory Record Inaccuracy Analysis
… the behavior of inventory record inaccuracy (IRI) when it is influenced by demand, supply and lead time uncertainty in both online and offline retail environment separately. Additionally, this study identifies the susceptibility of the inventory systems towards IRI due to conventional perfect …

PROTECTION OF ISCHEMIA REPERFUSION INJURY IN MURINE LIVER BY GENE SILENCING OF COMPLEMENT 3
… documented that ischemia reperfusion injury (IRI) in the liver is associated with complement pathway activation. Thus, blocking complement 3 (C3) genes using a small hairpin RNA (shRNA) can potentially prevent liver IRI. Gene silencing of C3 in vivo was achieved via the administration of shRNA …

Role of the macrophage in acute kidney injury
Ischaemia/Reperfusion Injury (IRI) is the most common cause of acute kidney injury- a devastating clinical problem lacking any specific treatments to promote renal recovery. Macrophages (Mφ) are pleiotropic cells of the innate immune system, with roles spanning host defence, cytotoxicity, clearance …

Targeting Mitochondrial ROS Production in Kidney Transplantation
Ischaemia reperfusion injury (IRI) is an inevitable consequence of transplant practices but is associated with reduced levels of graft function and survival. In addition, concerns regarding the severity of IRI has restricted the greater use of organs from the available donor pool. Critically, no …

Complement activation and effector pathways in ischaemia reperfusion injury and at the interface with adaptive immunity
Ischaemia reperfusion injury (IRI) is an important source of morbidity and mortality and contributes to renal transplant failure. Renal IRI is known to be mediated by complement, which causes direct injury to the transplant and stimulates the adaptive immune response against transplant antigens. …

Treatment of Ischemia Reperfusion Injury with RNA Interference
Ischemia reperfusion injury (IRI) occurs during transplantation and causes apoptosis and inflammation. The purpose of this research was to determine the effect of caspase-3, complement 3, and RelB gene silencing in the reduction of IRI using an in vitro model. LLC-PK1 cells were used along with …

Development of a smartphone application to measure pavement roughness and to identify surface irregularities
… in terms of International Roughness Index (IRI), which is often measured using inertial profilers. Inertial profilers are equipped with sensitive accelerometers, a height measuring laser, a distance measuring instrument, etc., to measure pavement profile. Modern smartphones are equipped with …

The Roots of Feminist Invocations in Post-Revolutionary Iran
… of efforts by the Islamic Republic of Iran (IRI) to institutionalize an archaic image of the ideal Muslim woman have produced results contrary to what was intended. The expansion of women's education in post-revolutionary Iran identified as an unintended consequence of the revolution has been …

Use of smartphones to measure pavement roughness across multiple vehicle types at different speeds
… is recorded as International Roughness Index (IRI) and is collected via a data collection vehicle (DCV) using a combination of lasers, accelerometers, and a distance measuring device. Unfortunately, this practice is cost-prohibitive to conduct on an annual basis. However, recent studies have …

THEORY OF MIND, EMPATHY, AND IDENTITY PROCESSING STYLE: EXAMINING INTERRELATIONSHIPS AND ADVANTAGES OF ACTING EXPERIENCE
… distress) of the Interpersonal Reactivity Index (IRI) was used to measure empathy. It was hypothesized that students with acting experience would perform significantly better than those without acting experience on all measures of ToM and empathy. It was also hypothesized that the way emerging …

Immunological Impact of CLI-095 on Dendritic Cell Maturation and Hypoxia-re-oxygenation induced inflammatory injury
… Introduction: Ischemia reperfusion injury (IRI) activates innate immunity through the engagement of Toll-Like Receptors (TLRs) by endogenous ligands. TLR4 expressed within the kidney is a potential mediator of innate activation and inflammation. Stimulation of TLR4 induces distinct patterns …

Examining the regional physiology of the transplant kidney during normothermic machine perfusion.
Ischaemia-reperfusion injury (IRI) is an unavoidable consequence of deceased-donor kidney transplantation that has a profound effect upon both immediate and long-term graft function. Disruption to microvascular perfusion (MVP) and tissue oxygenation (PtO2) are central to the development of IRI, but …

Developing pavement preservation and mitigation strategies using Pavement ME design guide for Rhode Island DOT
… Pavement ME. The International Roughness Index (IRI), Longitudinal Cracking, and Permanent Deformation (Rutting) in both the asphalt layer and the total structure were predicted using Pavement ME to determine the sensitivity of flexible pavement performance with varying pavement parameters, such …

An investigation into the relationships between cloze test scores and informal reading inventory scores of fifth grade pupils
… cloze test and an informal reading inventory (IRI) were administered to all subjects over a six-week period during the months of April and May of 1972. For purposes of this study, the IRI was accepted as the criterion with which all other variables were compared. Teachers' estimates of their …
