PR-221-9215-R01 Manufacture Pre-Production Gas Flow Measurement System
Authors: Lagus P.L. , Grot R.A.
Published: August 2023

Measurement of the throughput of a natural gas compressor can be undertaken using a constant flow tracer dilution technique. In this technique, a constant flow of tracer is introduced into the piping upstream of the compressor while samples of diluted tracer are measured downstream of the compressor. The samples are analyzed using a specially configured analyzer. Knowledge of the injection rate and injection concentration coupled with the downstream measurement of tracer concentration allows the throughput through the compressor to be calculated. Under this contract, three systems were fabricated and were to be provided to operating pipeline companies for use and evaluation. Each system consisted of an SF6 analyzer, a high-pressure SF6 tracer injection module, and a gas sampling and analyzer support module. The design was modified based on the findings from the field evaluation and a final inspection.
DTRS56-04-T-0009 Evaluation of the Interaction of Mechanical Damage and Welds
Authors: Carroll L.B. , Fredi Abdefttah , Semiga Vlado
Published: August 2023

This project was completed to support the development of a guidance note for the disposition of welds interacting with pipe wall mechanical damage (dents, wrinkles, and ovality) and thus allow a more rational treatment of these forms of damage. The intent is not to evaluate the life of welds interacting with dents wrinkles and ovality, but rather to identify when the interaction is significant and needs to be considered explicitly. Based upon the criteria developed in this project, inspection results that indicate the presence of pipe wall deformation in the vicinity of a girth weld or long seam weld can be used to assess if the interaction is significant and must be treated as a repairable defect. This project report includes a discussion of the following work:

� Development of criteria for weld interaction with restrained rock dents, pipe ovality, and wrinkles;

� Development of a means of considering pressure fluctuation severity in these criteria, and

� Development of guidance and recommendations on how to consider the effects of soil confinement. The criteria do not predict the actual life of a mechanical damage feature, but instead, present a means of defining the interaction distance between a damage feature and a weld. The processes have been established based on numerical modeling results with a detailed consideration of the effects of both physical and numerical variables. Due to the virtually limitless combination of weld seam geometries, weld quality, and residual stress fields, these parameters were not explicitly included in the numerical models. Instead, potential weld quality issues and residual stresses are addressed using an appropriate and conservative fatigue design curve while the weld geometry effects have been included with the selection of a stress concentration factor applied to the numerical modeling results.

PR-316-17200-R03 A Study of the Effects of Liquid Contamination on Seal Performance
Authors: Rimpel Aaron
Published: August 2023

This project is a continuation of research to enhance dry gas seal (DGS) reliability. Previous work reviewed failures from literature and experience of manufacturers and end-users and identified that liquid contamination was the most common cause, but it was concluded there was insufficient quantitative data to base recommendations on for further DGS reliability enhancements. Therefore, experimental and analytical investigations were pursued to fill the void. The ultimate objective was to be able to predict DGS failures due to liquid contamination, which could lead to greater DGS reliability through improvements in design, instrumentation, and monitoring. From the previous project phase, testing had demonstrated that the introduction of small quantities of oil (liquid mass fraction up to 3%) produced a slight increase in torque but impacts on temperatures and leakage were negligible. Previous simulations demonstrated converged two-phase computational fluid dynamics (CFD) with conjugate heat transfer (CHT) solutions of the seal and reasonable trends, but the agreement with test data was lower than desired.

The current project phase made significant improvements to the single- and two-phase CFD simulation of the DGS, lowering the discrepancy of all previously reported performance parameters. The current simulations were performed only at the 700 psi supply pressure case. Ideal gas was used, and CHT coupling was used to predict temperatures of the primary ring. The previous wall thermal boundary conditions were not well understood, so the current work focused on establishing performance with adiabatic walls.
PR-335-203810-R01 Review of Xray Computed Tomography Performance
Authors: Malinowski Owen
Published: August 2023

X-Ray Computed Tomography (XRCT) has been utilized for decades in medical and industrial imaging applications. The technology uses penetrating X-ray radiation to image the internal structure of an object by measuring attenuation along multiple transmission paths through the object. XRCT is a promising technology for application in imaging and sizing of flaws in oil and gas transmission pipelines and has been used in such applications in the past. However, the performance of the technology in this specific application to flaw sizing in oil and gas pipelines has not been fully evaluated. The purpose of this report is to provide a complete statistical analysis of the flaw sizing error of XRCT by consolidating flaw sizing information from past projects where both XRCT data and cross-sectional micrographs were available for comparison. Sizing error data were evaluated as a whole and as segments in order to determine overall sizing performance and per-flaw-type/per-measurement-type sizing performance, respectively

DTRS56-02-D-70036A Potential Impact Radius Formulae for Flammable Gases other than Natural Gas
Authors: Baker Michael
Published: August 2023

The original derivation of the PIR formula referenced in 49 CFR 192 is contained in the Gas Research Institute (GRI) report by C-FER Technologies (C-FER), "A Model for Sizing High Consequence Areas Associated with Natural Gas Pipelines" (Stephens 2000). It must be recognized that this formula was derived solely on the premise that thermal radiation from a jet/trench fire is the dominant hazard related to pipe rupture and subsequent ignition. Since natural gas is non-toxic and significantly lighter than air, this premise is valid. However, there are certain pipeline operators transporting flammable gases other than natural gas (e.g. hydrogen) that will be governed by the jet fire hazard, and thus there is a need for the derivation of PIR formulae for use in identifying high consequence areas for these pipelines. While the C-FER report provides a basis for derivation of such formulae, the dimensionless values for emissivity factor, release rate decay factor, and efficiency factor used in the original derivation of the PIR formula have not been validated or optimized for flammable gases other than natural gas.

The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of the Pipeline and Hazardous Materials Safety Administration, the Department of Transportation, or the U.S. Government.

C-FER Technologies (1999) Inc., ("C-FER") conducted a multi-phase study to further advance the ability to predict the remaining casing burst capacity for underground natural gas storage wells. This project is co-funded by the Pipeline Research Council International, Inc. (PRCI) and the US Department of Transportation (DOT), Pipeline and Hazardous Materials Safety Administration (PHMSA).

This project included a literature review of casing corrosion logging technologies and remaining burst capacity prediction models. Three casing corrosion logging tools, selected based on the outcome of a preceding PRCI casing logging tool test program, were tested to further evaluate their performance in detecting and sizing various metal loss features on casing specimens. Physical burst tests with capped ends were conducted on 20 specimens selected from the logged casing joints to benchmark the burst prediction models. Advanced finite element analysis (FEA) was also performed to evaluate the effect of in-situ downhole load conditions on the remaining burst capacity of corroded casing. A reliability-based framework was outlined to quantitatively address various uncertainties associated with the casing corrosion integrity management. This report summarizes the work completed, the key results and conclusions, as well as recommendations for future initiatives.

PR-457-17201-R04 Residual Gas Fraction Estimation Based on Measured Engine Parameters - Phase IV
Authors: Bajwa Abdullah , Kroeger Tim , Jacobs Timothy
Published: August 2023

Based on experimental characterization of the scavenging behavior of a cross-scavenged, piston-aspirated, two-stroke, natural gas engine in phase III of the current project, a computationally inexpensive simple scavenging model was improved in this phase. Experimental results using fast nondispersive infrared (NDIR) CO2 measurements from the cylinder and the exhaust, as well as experiments using unburned fuel pre-mixed in the scavenging chamber as a tracer for short-circuiting during scavenging, were used in this phase to validate the improved model. The model represents the fundamental phenomenological characteristics revealed by those experiments. The experiments and literature show that scavenging takes place by the following phenomena: blowdown, displacement of residuals by incoming air, mixing of residuals and air, and short-circuiting of fresh air. To reflect this, the improved hybrid model features the following: isentropic blowdown, non-isothermal perfect displacement, non-isothermal perfect mixing, and a concurrent direct short-circuiting of air (unmixed with residuals).

The validated improved hybrid model rectified the primary shortcoming of the phase III model. By adding the discrete short-circuiting zone, trapped mass could be modeled at both medium and high crankshaft speeds, whereas the phase III model could not capture the full scope of scavenging inefficiencies at medium speed using its perfect mixing stage alone. Furthermore, using the hybrid model to predict NOx using an exponential NO and shy;x-TER curve fit revealed that the improved phase IV hybrid model predicts NOx approximately as well as the experimentally-calculated TER from the phase III experiments.

Additionally, GT-Power, a 1D fluid dynamics and engine simulation software, was used to identify whether hybrid model tuning could be aided by relatively inexpensive 1D simulation rather than CFD or fast NDIR experiments. Using three-pressure analysis (with in-cylinder, exhaust, and scavenging chamber pressures as boundary conditions) and scavenging profiles derived from the hybrid model itself, GT-Power was shown to be a plausible tool for scavenging model tuning.
PR686-203903-R02 Ongoing InSAR Geohazard Monitoring of Pipeline Right-of Ways in the Appalachian Mountains
Authors: Down Murray
Published: August 2023

Ground displacement along pipeline corridors has the potential to compromise pipeline integrity. The Appalachian Mountain region is almost entirely classed as high landslide susceptibility by the United States Geological Survey (USGS) and crossed by numerous transmission pipelines and gathering lines. In phase I of this research project, 3vGeomatics successfully demonstrated a proof of concept on the effectiveness, reliability, and precision of using L-band ( ) SAR satellites for InSAR displacement monitoring of vegetated areas. The second phase of this project improved operational monitoring utility of long wavelength InSAR by leveraging a two and a half year dataset of long-wavelength satellite radar data with improved product formats to facilitate management of pipeline threats posed by both geohazards and third party encroachment. Potential encroachment threats are highlighted by new object detection capabilities that use the same raw SAR data to produce additional intelligence. As with the previous year's results, these phase-2 InSAR and new object detection results were compared with measurements from other sensors including differential light detection and ranging (LiDAR), visual field inspections, and aerial photographs. This project demonstrated the technological readiness and streamlined product formats delivering actionable intelligence from L-band SAR data for operational monitoring of ground displacement and other hazards over entire pipeline networks and associated infrastructure in vegetated areas.

PR261-193604-R01 Optimizing Stress Corrosion Cracking Management - Field and Economic Study
Authors: Beauregard Yannick
Published: August 2023

This work aims to improve pipeline segment prioritization for stress corrosion cracking (SCC) excavations. Specifically, it is aimed at optimizing the technical accuracy and the cost of the Association for Materials Protection and Performance (AMPP, formerly NACE) Stress Corrosion Cracking Direct Assessment (SP0204-2015) process by:

- evaluating the SCC susceptibility criteria of soil property parameters that were proposed in the first phase of the project (pH, resistivity, sulfide concentration, soil carbon dioxide (CO2) concentration, carbonate concentration, soil oxygen (O2) concentration, sulphate reducing bacteria (SRB) concentration, oxygen reduction potential (ORP), soil moisture content, soil effect on steel hydrogen permeation and electrochemical properties)

- investigating the technical and economic feasibility of using commercially available field instruments for the measurement of these soil parameters to overcome limitations of laboratory testing (e.g., sample preservation and external costs)

Soil sampling and testing was conducted at twenty-two dig sites in three geographic regions in the USA and Canada. On-site soil sampling and testing activities were conducted by field service providers using commercially available portable instruments. Soil samples were sent to laboratories for chemical analysis and for electrochemical characterization. The data analysis consisted of: (i) comparison of soil properties obtained at sites with and without SCC against the proposed SCC susceptibility criteria (ii) comparison of soil property data obtained in the field to those obtained through laboratory analysis (iii) comparison of soil property data obtained using different field and lab measurement techniques (iv) comparison of costs associated with performing in-field measurements to those of laboratory analysis.
PR-670-183826-R02 Extended Evaluation of LSM - Magnetic Measurements of Corrosion Flaws
Authors: Finch Graeme , Harmon Stuart
Published: August 2023

Integrity assessment of pipelines is vital to ensure that oil and gas pipes have adequate strength to prevent leaks and ruptures. Regular inspections are conducted to confirm safe operation conditions of pipelines. The industry's principle method for assessing pipelines is in-line inspection (ILI), involving the passing of a device along the inside of a pipe to assess the condition of the pipeline. ILI devices can be fitted with a number of sensors allowing various measurement parameters to be obtained simultaneously.

Not all pipelines are suited to ILI for reasons such as small diameter, obstructions within the pipe, or insufficient access to deploy or retrieve the ILI tools. These pipelines are sometimes referred to as 'difficult to inspect'. Alternative methods for examining pipeline condition are required with a range of technologies collectively known as Large Standoff Magnetometry (LSM) offering a promising solution for detection of pipe defects from a distance, reducing the need for excavation.

LSM utilises coupling between defects and changes in the magnetic properties of the pipeline material as a method for evaluation of pipe walls to identify the location of areas that require repair or further monitoring. Trials of existing commercial instruments by the pipeline industry have shown sufficient promise to investigate these technologies further. However, the vendors have supplied limited information on the underpinning physics of both the materials being tested and the instrument technology, meaning that further study is required in order to build confidence in the technique.

The purpose of the project is to establish the ability of LSM to detect corrosion in API 5L pipe grades B to X70. The aim of Work Package 04 is to measure the magnetic fields of a range of pipe samples containing manufactured corrosion flaws taking into account variables such as standoff distance, pressure, nearby ferromagnetic objects, position of the corrosion flaw around the pipe, track alignment, and orientation with respect to Earth's magnetic field. The results of these measurements will be used to validate computational models, which can be used to predict the magnetic response of a wider range of pipe geometries.
PR-652-203801-R04 Magnetometer Noise and Resolution
Authors: Choudhury Sarah , Underhill Ross , Krause Thomas
Published: August 2023

Magnetometers are sensors that measure the magnitude and direction of a magnetic field. There are many types of magnetometers available, but they all rely on electromagnetic principles to measure fields. The most common types are Hall effect, anisotropic magneto-resistive (AMR) and fluxgate sensors. The goal of this study is to investigate several magnetometers to evaluate their capability to detect small changes in an ambient field. These small changes are on the order of 10 milligauss (1 �T) and are caused by the inverse-magnetostrictive effect, or Villari effect, from ferromagnetic pipes. The chosen magnetometer must have a low noise signal and a fine resolution to properly measure the field from the inverse-magnetostrictive effect. To evaluate the chosen magnetometers, multiple sets of measurements were made in a stationary magnetic field and the standard deviation of the data sets were calculated. The noise of some sensors was further investigated to verify that it was normally distributed.

In silico analysis of Nigella sativa bioactive compounds as fertility potential in folliculogenesis disorders
Authors: Amalia Amirul , Hendarto Hendy , Mustika Arifa
Published: August 2023

Context: The capacity to get pregnant is known as fertility. Every woman has reproductive rights to be fertile. In reality, there are still many cases of infertility. Infertility is due to impaired folliculogenesis. Low GDF-9 and estrogen receptors can be used as biomarkers in folliculogenesis disorders. Nigella sativa is a plant with medicinal properties as an antidote and protects against toxicity in the lungs, heart, liver, digestive tract, and reproductive system. Aims: To identify the potential of the bioactive compounds N. sativa as activators of GDF-9 and estrogen receptor proteins on fertility in an in silico study approach. Methods: All ligands from N. sativa extract were from previous studies, and protein preparations were taken from PubChem database. The conversion of the sdf file to pdb on the ligand was carried out using the OpenBabel v2.3.1 software. The drug-like molecule properties of chemical compounds from N. sativa were identified through a drug-likeness test on the SwissADME server and using PyRx v9.9.0 software, LigPlot+ v.2.2 software, and PyMol v2.5 software to analyze and visualize the potential of N. sativa compounds against GDF-9 and estrogen receptor. Results: Compounds cis-13,16-docasadienoic acid and cholestan-3-ol, 2-methylene-, (3β,5α)- have the lowest bond affinity, hydrogen, and hydrophobic interactions, as well as the same position of amino acid interactions to control. Conclusions: Cis-13,16-docasadienoic acid and cholestan-3-ol, 2-methylene-, (3β,5α)- can act as candidates for activating GDF-9 and estrogen receptors for fertility.
Temporalidades heterogéneas en las lecturas sobre la crisis de 2001: acontecimiento, experiencia, fantasma
Authors: Dillon Alfredo
Published: August 2023

A 20 años de 2001, este artículo revisa un corpus de lecturas elaboradas desde las ciencias sociales sobre la crisis de 2001 en Argentina, tomando como eje las temporalidades heterogéneas implicadas en las diversas interpretaciones de los hechos. La revisión del corpus se estructura a partir de tres ejes: primero, la tensión entre la excepcionalidad del acontecimiento y su inscripción en un proceso histórico; segundo, las experiencias de la crisis; tercero, la dimensión simbólica de la crisis entendida como fantasma cuya gravitación persiste en el presente. La crisis de 2001 ha sido interpretada como un punto de inflexión en el pasado reciente, y como una referencia imprescindible para construir una genealogía del presente. El análisis de las lecturas evidencia que en los hechos de 2001 se superponen temporalidades diversas: esa heterogeneidad contribuye a explicar por qué, pese a la distancia creciente con respecto a los hechos, el 2001 sigue siendo un pasado presente. Comprender esa persistencia requiere, a su vez, deconstruir el mito de la “eterna crisis” nacional.

Composites of polyethene terephthalate (PET) and groundnut husk fibres were produced. Recently, the interest in using natural fibres in bio-composite materials has grown because they are non-toxic, low-cost, and easy to recycle. In this paper, we present the effects of different types of fibre treatments on the mechanical properties of PET as composite materials made from groundnut husk and plastic water bottles (Faro). Mechanical and physical tests were carried out on the PET-GH fibre composite, such as burning rate, water absorption, Meyer’s hardness, modulus of rupture and impact strength.

Effects of percentage increase in PET and fibre on water absorption, burning rate, hardness, impact strength, and modulus of rupture were analyzed. SEM analysis was employed to study the morphology of the produced composite at different PET-GH loadings to establish the optimum interfacial adhesion of the polymer matrix.

Consumers can experience one of three levels of general satisfaction, namely if performance is below expectations, consumers will feel disappointed, but if performance matches expectations, customers will feel satisfied and if performance exceeds expectations, customers will feel very satisfied, happy or happy.

Service is a very important factor, especially for universities which in this case are engaged in services. Service to students is very important for the life of a university, because without students, the college will be closed. Thus, university service activities must be oriented to customer satisfaction, namely students. Maintaining satisfaction needs to be done to maintain positive attitudes of students as service users while minimizing negative attitudes that can be caused as a result of poor service quality.

Management HR Management is in the category of satisfactory / Satisfied. Judging from the scores of each statement item, it appears that Lecturers and Educators are satisfied with all aspects and services of HR management carried out by the "YAB" Academy of Physiotherapy.

In general, the level of satisfaction of Lecturers and Education Personnel is very good, but it is important for AKFIS YAB to continue to maintain and improve services to Lecturers and Educators by improving the performance of the services provided.

Obtaining demographic data was very important for the newly created Soviet state. Despite the difficult economic and political situation, the Soviet authorities tried to carry out censuses not only in the RSFSR, but also in other Sovietized republics. The first of them was the agricultural census of 1921 in the Azerbaijan SSR, the data of which, despite the methodological and technical shortcomings that force this data to be approached with reservations, are an exceptional historical and demographic source. The first All-Union census of 1926 was organized with the most developed methodology. The combination of the results of these censuses and other additional studies makes it possible to reconstruct the population size and ethnic composition of two newly created administrative units: Nagorno Karabagh Autonomous Region and Kurdistan uezd (the creation of which pursued not only regional, but also geopolitical consequences). If the homogeneous Armenian population of Nagorno Karabagh Autonomous Region was able to resist the discriminatory policies of the Azerbaijani authorities, partly due to the status of an autonomous region, the provincial status and the low level of development and self-identification among the Kurds easily led to the abolition of the province and the artificial reduction of the Kurdish population at the expense of “Turkification” and then “Azerbaijanization” of that narrow corridor between Soviet Armenia and Nagorno Karabagh Autonomous Region
