Over 100 years have elapsed since Sidney Ringer made the serendipitous discovery that calcium played a crucial role in amphibian cardiac contraction. Since then we have learned that this ion is an obligatory requirement for cardiac muscle of all species, and that the regulation of intracellular calcium levels is considerably more complex in the mammalian heart than previously thought. Part of this complexity is due to the involved design requirements of mammalian physiological processes. Another element of complexity is introduced by the quantitative differences in the involvement of various regulatory processes in different species. Finally, many significant technological advances in methods for investigating cardiac cellular functions have provided exciting experimental data. However, these data must be integrated into a unifying framework of knowledge of cardiac functions. Among the exciting recent developments are the use of a patch clamp technique to discover different kinds of calcium channels, a highly refined skinned fiber technique to study calcium-induced calcium release, and calcium indicator dyes and laser diffraction and scattering techniques to study the dynamics of calcium handling by the cell. These studies have not only provided clues about the normal functioning of the myocardial cell but have also reinforced the notion that altered function of the sarcoplasmic reticulum during intracellular calcium overload can influence sarcolemmal electrical function.This symposium, organized by the Pharmacological Society of Canada, examined some of the more recent technological advances in the field to provide a glimpse not only of the "state of the art" but also of future directions.This symposium was made possible by generous financial assistance from Boehringer Ingelheim (Canada) Ltd., Bristol-Myers Pharmaceutical Group, Canadian and Manitoba Heart Foundations, Ciba-Geigy Canada Ltd., Du Pont Canada Inc., Hoffmann LaRoche Ltd., Merck-Frosst Canada Inc., Miles Laboratories Inc., Nordic Laboratories Inc., Pfizer (Canada) Inc., Rhône-Poulenc Pharmaceuticals Inc., G.

In the deep coal mines of OKD, Inc., both bolts and long bolts of different designs are used for the rock massif and steel arch support reinforcement. Continuous measurement of forces in 6 strand bolts and 1 cable bolt (long bolts, generally) was carried out during the trial operation of the modified Room and pillar mining method at Mining operation 2, site North, OKD, Inc. Hydraulic dynamometers were installed on these long bolts and a monitoring of forces took place throughout the life-time period of the mining panel No. V. From this measurement, a knowledge of their different load behavior with respect to the input stress parameters was obtained. The input intensity of the force applied to the bolting elements is burdened by losses of various kinds. The subject of the article is a description and analysis of the intensity of the initial stressing force applied to individual long bolts (with a threaded clamping bush or wedge barrel) and quantization of short-term stress losses with a description and analysis of these.

The strong conveyor belt has been widely used in mines, ports, wharves, power plants, steel mills, and other fields. It is one of the main transportation equipment in modern production. In coal mine production, the logistics conveyor belt is essential equipment. The increased load can scratch and age the conveyor belt. Then, coupled with the elongation of joints, the equipment fails. This work designs an X-ray Photoelectric (XP) collector for logistics transportation and puts forward the design scheme. This work expounds on the hardware circuit of the XP collector, mainly based on the Image Capture Card (ICC) of the S8865 module and the serial/parallel data acquisition board based on the AD7667 chip. In the test, the Field Programmable Gate Array (FPGA) development tool ISE of Xilinx company is used to design the software of the XP collector to collect logistics X-ray signals. The oscilloscope analyzes the ICC control signal RESET, which repeatedly appears in a certain period. The S8865 module is controlled to collect X-ray signals continuously; the analog output signal of the S8865 module is observed. Under the control of a 1 MHz clock, the S8865 module outputs a stable analog signal. Similarly, observing the differential signal output of the differential processing circuit on the ICC through the oscilloscope finds that the differential signal is consistent with the original signal. Further positive input/output of the signal conditioning circuit of the serial/parallel data acquisition board is observed after the differential signal is switched. The single-ended signal after switching is consistent with the differential signal’s positive input signal.

Background:We recently reported Phase 2 SLE trial results of obexelimab, an FcγRIIb agonist (suppressor of B cell activation). Obexelimab did not meet the primary endpoint (% of patients without flare at Day 225) (p=0.183) but other endpoints such as time to flare (p=0.025) were met.Objectives:1. To assign SLE patients to phenotypic subsets based on patterns of gene expression in immune-related pathways.12. To explore the association of immune patterns and clinical response to obexelimab.Methods:This analysis included 71 of the 104 participants in the obexelimab study, those who either completed the protocol or terminated for disease flare, if there were adequate blood samples (biomarker subset). At screening, patients were assigned to clusters based on 41 SLE co-expression signature modules from the Human Immune Phenotyping Consortium via unsupervised random forest and K-means clustering.2Other markers of SLE disease were also examined. TheBOLD3study design mandated withdrawal of background immunosuppressants, supporting less ambiguous pharmacodynamic analysis as the trial progressed.Results:Immune pathway expression patterns of 7 patient clusters (Fig 1a) confirmed our prior characterization of 200 non-overlapping SLE patients.2The biomarker subset retained a trend of longer time to first flare in patients receiving obexelimab (n=38) vs placebo (n=33) (Fig1b, HR 0.61, p=0.11). A smaller set of only Clusters 3 and 6 demonstrated marked increased time to flare in the obexelimab group (n=13) compared to placebo (n=14) (Fig 1c, HR 0.22, p=0.025). Obexelimab had no effect on other clusters (Fig 1d). The responder clusters shared low expression of inflammation modules (p < 0.001) compared to other clusters and high expression of T Cell, immune response, cell cycle, mitochondrial modules (all p < 0.001) and B Cell modules (p=0.006). We therefore sorted patients by these specific features regardless of cluster assignment. Figure 2 shows significant impact of obexelimab on time to flare in 64 patients with B Cell pathway activation (HR 0.5, p=0.038), although less robust by itself than found in Clusters 3 and 6. In a group with high B or plasma cell modules but low inflammation (n=46), treatment effect increased (HR 0.35, p=0.019). Between Screening and Baseline, as brief steroids were given and background treatments withdrawn, expression of B Cell and Plasma Cell pathways increased. Both then decreased after treatment with obexelimab but not placebo (p< 0.0001 and p< 0.001 respectively), an effect not seen with other immune pathway modules.Conclusion:Precision medicine for SLE has been hampered by heterogenous immune signals with variable expression. Clustering of patients by gene co-expression pathways enabled an efficient, hierarchical array that reduplicated results of a prior SLE cohort, suggesting these are not random phenotypes. Of these 7 reproducible SLE subsets, the combination of clusters 3 and 6 distinguished an obexelimab responder population of 27 out of 71 subjects (38%) with high expression of B and T Cell modules and cell activation pathways. Focus on the defining features shared by these clusters revealed specific factors associated with response, enabling inclusion of some patients from other clusters in an optimized responder population of 46/71 (65% of subjects). B Cell and Plasma Cell pathways demonstrated mechanism-related pharmacodynamic effects of obexelimab. Lack of responders with high expression of inflammation modules could implicate inhibitory factors to obexelimab within inflammatory pathways, potentially targetable by complementary treatments.References:[1]Banchereau Cell 165:1548 2016[2]Lu ACR Abstract #2977 2017[3]Merrill Arthritis Rheumatol 69: 1257 2017Disclosure of Interests: :Joan T Merrill Grant/research support from: Xencor, Bristol Myers Squibb, Glaxo Smith Kline, Consultant of: Xencor, Abbvie, UCB, Glaxo Smith Kline, EMD Serono, Astellas, Remegen, Celgene/Bristol Myers Squibb, Exagen, Astra Zeneca, Amgen, Jannsen, Servier, ILTOO, Daitchi Sankyo, Lilly, Paid instructor for: Abbvie, Bristol Myers Squibb, Joel Guthridge Grant/research support from: Xencor, Bristol Myers Squibb, DXterity, Debra Zack Shareholder of: Xencor, Employee of: Xencor, Paul Foster Shareholder of: Xencor Inc, Employee of: Xencor Inc, Bart Burington Shareholder of: Xencor Inc, Employee of: Xencor Inc, Ly Tran: None declared, Miles Smith: None declared, Judith A.

Gastric ulcer is still a health problem in Indonesia. The leaves of cincau (Cyclea barbata Miers) and mangosteen peel (Garcinia mangostana Linn) have been investigated to have gastroprotective effects. This study aims to determine the effect of gastroprotector from the combination of Cincau leaves and mangosteen peel. This study used the post test only control group design. Wistar male rats were divided into 6 groups. Group I was a healthy control group and the second group was an untreated negative control. Group III is positive group treated with Ranitidine (0.016 g / kg BW). Groups IV, V, and VI were given green leaves of cincau (13.5 g / kg BW), mangosteen peel (25 g / kg BW) and 1: 1 combination. Treatment was performed for 14 days. On day 14 1 hour after treatment, all groups (except group I) were given 96% oral ethanol induction at a dose of 5 g / kg BW. On the 15th day the animals were sacrificed by means of anesthesia using chloroform. The area of the tukak is calculated by ImageJ and then calculates the index parameters of the ulcer and the protection ratio. The stomach is made of a hitopathologic preparation with Hematoxylin and Eosin (HE) and Immunohistochemistry (IHC) preparations to observe COX-2 expression. The index data of ulcer, protection ratio, gastric mucosal damage score and number of cells expressing COX-2 were statistically analyzed by SPSS program. The results showed that the combination of green leaves and mangosteen leaf ratio of 1: 1 had a gastroprotective effect by inhibiting the gastric induced index, increasing the ratio of protection, reducing total mucosal damage and inhibiting the expression of COX-2 protein in rat stomach cells significantly (p <0 , 05). Giving combination of Cincau leaf and mangosteen peal of 1: 1 able to give gastroprotective effect.

Wide-bandgap semiconductors have a significant advantage over conventional Si-based electronics by leveraging materials properties to achieve higher breakdown voltage, lower on-resistance, and high-frequency operation. For electric vehicle drivetrains, this translates to higher efficiency and power density, resulting in more miles driven per charge. This move towards wide-bandgap power electronics is necessary to achieve the U.S. Department of Energy (DOE) power electronics density target of 100 kW/L. Vertical gallium nitride-based power devices are expected to exceed Si and even SiC-based systems with the promise of increased performance and power density. Compared to lateral GaN devices, a vertical topology promotes more efficient scaling towards high-power applications, where both high voltage and high current are necessary. This talk describes our team’s effort towards developing vertical GaN MOSFETs. The results of Sandia’s first-generation device demonstrator serve as a milestone in the path of producing devices rated for 1200-V and 100-A operation. The vertical GaN trench MOSFET is unique compared to Si- or SiC-alternatives in that the doped layers comprising the source and body regions are grown by epitaxy rather than formed by ion implantation. Challenges with selective-area doping in GaN add additional complexity to the design of a trench MOSFET. In addition, the lack of a high-quality native oxide in GaN means that the gate dielectric must be deposited rather than thermally grown. The devices produced at Sandia rely on atomic-layer-deposited thin films for the gate dielectric (primarily Al2O3 or SiO2). First-generation results demonstrate devices capable of 400 mA/mm drain current, 108 on/off ratio, and a positive threshold voltage near 8 V. More recently, devices capable of blocking 500 V in the off-state have been demonstrated. Device failure in the off-state results from high fields in the gate dielectric, which can be minimized by reducing the trench etch depth or by increasing the voltage rating of the drift region. However, further shielding of the gate dielectric to achieve substantially higher off-state voltages requires significant changes to the device architecture which are reliant on selective-area doping. In addition, device-killing defects either from the starting substrate, the epitaxy, or defects introduced during processing limit yield for large-area devices and present a substantial obstacle to scale devices for high-current operation. Hence, methods for reducing cell pitch and increasing packing density are highly valued. In this talk, we will discuss the path forward for achieving higher breakdown voltages and high-current operation using GaN-specific strategies to achieve better performing devices, as well as some of the challenges for vertical GaN development. This work provides a foundational platform for developing next-generation power electronics that employ wide bandgap, gallium nitride semiconductors.

The monograph discusses the application of nonparametric criteria of agreement (Kolmogorov, Cooper, Kramer-Mises -Smirnov, Watson, Anderson -Darling, Zhang) when testing simple and complex hypotheses.
The appendix contains tables containing percentage points and statistical distribution models necessary for the correct use of criteria when testing simple and, most importantly, various complex hypotheses.
In comparison with the first edition, more attention is paid to the application of criteria in non-standard application conditions, in particular for the analysis of large samples.
It is shown that in applications, the properties of criteria can change significantly due to the presence of rounding errors, and this must be taken into account when forming statistical conclusions.
Following the recommendations in data analysis will ensure the correctness of statistical conclusions and increase their validity.
It is designed for specialists who, in one way or another, face issues of statistical data analysis, processing of experimental results, the use of statistical methods to analyze various aspects and trends of the surrounding reality in their activities. It will be useful for engineers, researchers, specialists of various profiles (physicians, biologists, sociologists, economists, etc.), university teachers, graduate students and students.

Martin, Derek, i Peter Stacey, red. Guidelines for Open Pit Slope Design in Weak Rocks. CSIRO Publishing, 2018. http://dx.doi.org/10.1071/9781486303489.
Pełny tekst źródłaStreszczenie:
Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability.
Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves.
This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, monitoring, surface water control and closure of weak rock slopes.
As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners.
This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting rock slope stability and reliability in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring.
Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process.
This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

The world's largest demonstrator of a revolutionary energy system in desalination for drinking water production is in operation. MIDES uses Microbial Desalination Cells (MDC) in a pre-treatment step for reverse osmosis (RO), for simultaneous saline stream desalination and wastewater treatment. MDCs are based on bio-electro-chemical technology, in which biological wastewater treatment can be coupled to the desalination of a saline stream using ion exchange membranes without external energy input. MDCs simultaneously treat wastewater and perform desalination using the energy contained in the wastewater. In fact, an MDC can produce around 1.8 kWh of bioelectricity from the energy contained in 1 m3 of wastewater. Compared to traditional RO, more than 3 kWh/m3 of electrical energy is saved. With this novel technology, two low-quality water streams (saline stream, wastewater) are transformed into two high-quality streams (desalinated water, treated wastewater) suitable for further uses. An exhaustive scaling-up process was carried out in which all MIDES partners worked together on nanostructured electrodes, antifouling membranes, electrochemical reactor design and optimization, life cycle assessment, microbial electrochemistry and physiology expertise, and process engineering and control. The roadmap of the lab-MDC upscaling goes through the assembly of a pre-pilot MDC, towards the development of the demonstrator of the MDC technology (patented). Nominal desalination rate between 4-11 Lm-2h-1 is reached with a current efficiency of 40 %. After the scalability success, two MDC pilot plants were designed and constructed consisting of one stack of 15 MDC pilot units with a 0.4 m2 electrode area per unit. This book presents the information generated throughout the EU funded MIDES project and includes the latest developments related to desalination of sea water and brackish water by applying microbial desalination cells.

Guidelines for Evaluating Water in Pit Slope Stability is a comprehensive account of the hydrogeological procedures that should be followed when performing open pit slope stability design studies. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book expands on the hydrogeological model chapter in the LOP project's previous book Guidelines for Open Pit Slope Design (Read & Stacey, 2009; CSIRO PUBLISHING).
The book comprises six sections which outline the latest technology and best practice procedures for hydrogeological investigations. The sections cover: the framework used to assess the effect of water in slope stability; how water pressures are measured and tested in the field; how a conceptual hydrogeological model is prepared; how water pressures are modelled numerically; how slope depressurisation systems are implemented; and how the performance of a slope depressurisation program is monitored and reconciled with the design.
Guidelines for Evaluating Water in Pit Slope Stability offers slope design practitioners a road map that will help them decide how to investigate and treat water pressures in pit slopes. It provides guidance and essential information for mining and civil engineers, geotechnical engineers, engineering geologists and hydrogeologists involved in the investigation, design and construction of stable rock slopes.

Abstract This paper describes the development and implementation of a computerized knowledge-based system (SmartMix) that provides assistance to concrete mix designers by automatically generating designs of concrete mixes. These concrete mixes can be used for the construction of power plants, buildings, bridges, etc. The generation of designs by SmartMix is based on current design practices and heuristic rules. SmartMix incorporates current empirical data and its knowledge base can be expanded to include data gathered in the future. SmartMix is a fully operational system and has been designed taking into account the existence of several concrete plants geographically distributed that produce concrete mixes. This is an important consideration because different materials will be available depending on the geographic location of a particular plant. The mix design provided by SmartMix addresses the specific requirements and characteristics of the concrete plant that is to produce it. SmartMix was built using a knowledge-based systems environment called Smart Elements from Neuron Data. The system’s domain expertise consists of heuristic knowledge, statistical information and intelligent objects. The system has improved the reliability and consistency of the new concrete mix designs and has reduced dramatically the time and cost associated with the design of concrete mixes with respect to the manual process. The development of SmartMix was completed in 1995 as a result of a Joint Research Venture project between Pildysh Engineering Inc. and the Alberta Research Council. SmartMix has been in use since the fall of 1995 and is currently being used by Pildysh Engineering Inc. as a primary tool for the design of concrete mixes. Substantial cost savings and quality improvement have been achieved as a result of the implementation of SmartMix.

Enbridge Inc. operates the world’s longest crude oil and refined liquids pipeline system. The company owns and operates Enbridge Pipelines Inc. (the Canadian portion of the Enbridge crude oil mainline) and a variety of affiliated pipelines in Canada and the United States. It also has approximately, a 12% interest in Enbridge Energy Partners, L.P. which owns the Lakehead Pipeline System in the United States. These pipeline systems have operated for over 50 years and now comprise approximately 15,000 kilometers (9,000 miles) of pipeline, delivering more than 2.2 million barrels per day of crude oil and refined liquids. The combination of the Enbridge System in Canada and the Lakehead System in the United States brings together the primary transporter of crude oil from Canada into the United States. It is also the only pipeline that transports crude oil from Western Canada to Eastern North America, serving all of the major refining centres in the province of Ontario as well as the Great Lakes region of the United States. The system consists of approximately 9000 kilometers (5,600 miles) of mainline pipe in Canada, and 5300 kilometers (3,300 miles) of mainline pipe in the United States. The Canadian portion of the pipeline system extends from Edmonton, Alberta as the primary initiating facility, across the Canadian prairies to the U.S. border near Gretna, Manitoba. It continues again from the U.S. border near Sarnia, Ontario, to Toronto, Ontario, and Montreal, Quebec, with lateral lines to Nanticoke, Ontario, and Niagara Falls, Ontario. The total length of the pipeline right-of-way is nearly 2300 kilometers (1,400 miles).

A chronological historiography of Mies van der Rohe’s architecture uncovers a constant reassessment of his work by critics in changing eras. By the 1990’s he was reassessed as a more complex figure than previously understood. Publications, such as, The Presence of Mies, and, Mies in Berlin/America revealed new ways to conceptualize his work. Today he’s a well-worn symbol of the elite European architect in a necessary, refresh¬ing, and fruitful landscape of broader inclusivity. However, in the canon of Western Modern Architecture Mies is the most mysterious; an architect who conceals multitudes with his silence. Mies’s works are like tofu, his buildings act as tabula rasa in which new meanings can be absorbed within the constant, restless, and shifting tastes of architectural scholarship. Mies cultivated this mystery by saying one thing and doing another. Like Andy Warhol he reduced explanations of his design process to the point of rationalist banality. But a closer understanding of Mies’s philosophy betrays a much deeper surface. A new English translation of highlighted passages in Mies’s personal copy of Romano Guardini’s “Der Gegensatz” (The Opposite), gives a clue into how mysteries within Mies’s works are cultivated. For Mies, these passages revised the understanding of dualities as laid out by classic German philosophy. Hegel supported the synthesis of contradiction through a reposed resolution, but this passage declares an irreducible simultaneity present within paradox. Architecture is a relevant discipline for exploring dualities because it is a discipline steeped in both the rational and the spiritual, serving immediate and abstract needs. Reframing a transitional period in Mies’s career—the projects for the Ulrich Lange and Hubbe House—within the context of his meditations on Guardini reveals a new complexity embedded in the work. His quest to understand the nature of dualities is the underlying flavor of his work after the 1920s.

Baffinland Iron Mines Corporation is planning to utilize the iron deposits on the northern Baffin Island (Canada). The iron ore was discovered in the beginning of 1960ies. The mine is 100-142km from the sea shore (Milne Inlet or Steensby Inlet). The sea area from Milne Inlet and Steensby Inlet to North Atlantic is most of the year ice covered. Open water period may be only three months, from July to October. The operation is planned to be year-round. The amount of iron ore to be transported in the beginning of the production in 2014 is c. 18 million tonnes/year. The ore carriers are to be operated independently without icebreaker assistance. The ore carriers are assumed to operate at full draught both in loaded and ballast condition when operating in ice. The ship size was selected to be of main dimensions as a Dunkirkmax/Capesize vessel. There are two basic ore carrier alternative designs; The first alternative is conventional icebreaking vessel, which mainly operates by breaking ice with the bow. The second alternative is the so called Double Acting Ship (DAS). In the DAS concept the vessel is designed to operate bow first most of the time, in open water and in light ice conditions, but in severe ice conditions running astern. This paper describes the design process of the vessels including the basic requirements, operational conditions, transit simulations, model tests and the vessel designs.

Abstract Sufficient anchorage of dental implants, defined as mechanical engagement between implant and bone at the time of insertion, has been recommended for positive clinical outcomes, particularly in immediate loading protocols. Accurate measuring and analysis of stress and strain in the bone are imperative to understand anchorage from the biomechanics perspective. However, the stress and strain distributions at the bone-implant interface are impossible to measure in vivo. Therefore, the aim of this study was to develop and validate an explicit continuum finite element analysis (FEA) to investigate the stress and strain in a bone surrogate during the insertion of a dental implant: with cutting flute (CF) and without (NCF). Ten dental implants (five with CF and five with NCF) were inserted into ten rigid polyurethane (PU) foam blocks with a prepared pilot hole. During the insertion, a stereo digital image correlation (DIC) system was used to record in-plane deformation on the PU foam surface at a frequency of 1.0 Hz; and, surface von Mises strain, εv_DIC, was calculated (VIC-3D, Correlated Solutions Inc). In parallel, the insertion was simulated using FEA with explicit solver (Abaqus Explicit version 2017, Simulia). The PU foam was defined as an elastic-plastic material with a progressive crushable foam failure behaviour. The surface von Mises strain predicted from FEA, εv_FEA, was compared against εv_DIC. Uncertainty of DIC displacement measurement was 0.6 μm; and the static noise floor for the strain measurement was 500 microstrain (με). Coefficient of determination for εv_DIC and εv_FEA along a horizontal line for the CF and NCF implants were 0.80 and 0.78, respectively, which suggested the overall FEA performance was good. FEA results indicated that the cutting flute reduced the maximum shear stress in the PU foam and axial force which facilitated the insertion with less effort. This study demonstrated the successful combination of mechanical testing and FEA to better understand the mechanics of dental implant insertion.

The Elastic Wave (EW) technology has a proven record of detecting longitudinal cracking in gas and liquid pipelines. Prior to the initiation of this project, the technology had been based on a 36" pipe diameter with conversion kits covering 30", 32" and 34". Bend passing capability was 3D back to back, changing to 5D on the 30" build. To extend the technology over a greater range of pipe diameters and to incorporate 1.5D bend-passing capability on the smaller sizes required a radical re-design of the whole system. The brief of this project was to design a system capable of operating over the size range from 20" to 48", to produce a mechanical arrangement that enabled 1.5D bend passing on the 24" to 30", and to provide built-in gas by-pass capability for all sizes from 24"to 48". The project has been completed. Designs have been schemed for 20"to 48". A 24" 1.5D tool and a 36" 3D tool have been designed, manufactured and tested. The mechanical integrity and defect detection capabilities of both vehicles have been proven. Seven commercial inspection operations were successfully completed in 2000, collecting a total 572.8km (355.9 miles) of EW data.

The Federal Aviation Administration (FAA) advisory circular AC 150/5100-13 authorized the use of state highway material specifications at nonprimary public-use airports serving aircraft less than 60,000 pounds gross weight. This approval is based on the condition that the safety and life span of these airports will not be adversely affected. The use of highway materials provides the Illinois Department of Transportation (IDOT) with benefits, including cost, expertise, material availability, and sustainability. This study investigated the feasibility of using highway mixes for nonprimary airport pavements. Three classes of mixes were evaluated—namely, IDOT highway mixes, IDOT state airport mixes, and FAA airport mixes. The matrix consisted of 18 mixes: 15 surface and 3 binder mixes. The 15 surface mixes comprised seven laboratory-designed (five highway, two airport) and eight plant-produced mixes (four highway, four airport). All binder mixes were airport mixes and had the same composition and mix design parameters as highway mixes. Mixture performance was evaluated using the Hamburg wheel-tracking test (HWTT) to evaluate rut potential, the Illinois flexibility index test (I-FIT) to assess cracking potential, and the tensile strength ratio (TSR) test to evaluate moisture susceptibility. Performance testing was performed at both air voids of 4% and 7% corresponding to the initial in-place densities of nonprimary airports and highways, respectively. From the HWTT results, highway mixes had lower rut potential than airports mixes. With respect to the TSR test, airport mixes had lower tensile strengths than highway mixes. However, the TSR values (ratio of conditioned to unconditioned tensile strength) were similar for highway and airports mixes. The I-FIT results demonstrated comparable results between highway and airport mixes. Airport mixes had higher and comparable flexibility index for laboratory and plant mixes, respectively. By leveraging highway construction materials and methods, nonprimary airports could be constructed with greater expertise using more sustainable pavement materials that may yield reduced costs.

Design requirements for hydrogen pipelines are still evolving. Although there are several hundred miles of hydrogen pipelines throughout the world, most hydrogen pipelines are designed to transport hydrogen only short distances, from the production facility to the end-user. Many such applications typically represent only a few hundred feet of pipeline and operate with maximum pressures of considerably less than the 1,000 psi absolute (psia) or more that would likely be required for long-distance pipeline transmission of hydrogen. The safety record for these pipelines is considered to be very good. This safe history notwithstanding, the definition of required safety margins, codes, and standards for application to large-scale hydrogen transport remains a work in progress. It is therefore not possible at this time to definitively specify the design details of hydrogen transmission pipelines. However, based on the design parameters of some hydrogen pipelines and on experience with natural gas pipelines, it is reasonable to suggest some design parameters that could very well be applicable to the flow rates, distances, and pressures associated with the long-distance transmission of hydrogen via pipeline.

This study reviews the Illinois Department of Transportation’s full-depth asphalt, limiting strain criterion, and asphalt over rubblized concrete design procedures, considering technological advancements in hot-mix asphalt—namely, the increased use of recycled materials and modified asphalt binders. The researchers evaluated the current |E*| algorithm by conducting laboratory tests with four mix designs and seven asphalt binders of different Superpave performance grades. They compared predictive models, including the current Illinois modulus algorithm as well as the Witczak, Hirsch, and newly developed Illinois Center for Transportation (ICT) Bayesian neural network (BNN) models. The ultrasonic pulse velocity (UPV) nondestructive test for modulus and field modulus measurements was evaluated as well. Subsequent tasks involved reviewing current fatigue endurance limit (FEL) criteria from an adapted protocol for the four-point bending beam fatigue test. This study found that typical hot-mix asphalt modulus values in Illinois are underestimated compared to modern mixes, suggesting potential savings by allowing an increased modulus value to be used, reducing layer thickness design. Low-temperature performance grades significantly influenced modulus, and the developed ICT BNN predictive model outperformed traditional ones. While UPV was promising for modulus screening, challenges related to material properties assumptions were identified. The current stage of research on assessing modern mixes’ FEL reveals the complexity of observing FEL using simplified methods. To advance this objective, a concept of acceptable stiffness ratio (SR) is introduced. In these cases, exceptionally long fatigue life would be obtained for mixes that demonstrate an acceptable drop in SR within 10,000 cycles, with no apparent evolution of the damage state. The most conservative estimation of strain level that would result in acceptable SR aligned with IDOT’s current 70 microstrain FEL criteria. On the less conservative side, allowing a 10% drop in SR within 10,000 loading cycles could increase the acceptable SR < 1 strain level as high as approximately 180 microstrain, with caution needed regarding evolving mobility trends and environmental stressors including the changing climate.

Transportation has an enormous impact on the U.S. economy and on the lives of all Americans. Many modes of transportation rely on pavement, but pavement conditions deteriorate over time because of the combined effects of traffic and climate. Exposure to moisture often causes premature failure of asphalt pavements as it reduces the stiffness of the asphalt and enables stripping of the asphalt from the aggregate. This research evaluates the effectiveness of clay nanomaterials (i.e., nanoclays) in improving the resistance of hot mix asphalt (HMA) to moisture damage and compares the enhancement results to anti-stripping additives commonly used in pavement construction. Two types of surface-modified nanoclay, lime-treated aggregate, and two amine-based liquid antistripping agents (HP Plus and LOF 6500) were evaluated for improving HMA’s moisture resistance. All additives tested for reducing moisture damage resulted in dry and wet tensile strength of the modified mixes higher than the minimum specified by Caltrans 2018 Standard Specifications (100 psi for dry tensile strength and 70 psi for wet tensile strength). The Tensile Strength Ratio (TSR) of all HMA modified mixes was higher than 0.80, which is the minimum specified by the Superpave mix design method (Asphalt Mix Design Methods MS-2, Asphalt Institute) and exceeded the TSR of the control mix. The TSR for HMA mixes modified using nanoclays were comparable to those for HMA mixes modified using liquid antistripping and lime slurry treated aggregate. Liquid antistripping agents tested herein were the least costly additive at an approximately $2.0/ton added cost. This research can be used to better understand pavement deterioration to enable the most efficient and cost-effective construction and preservation of our nation's critical transportation infrastructure.

The U.S. Army Corps of Engineers (USACE) currently operates and maintains approximately 193 commercially active lock sites with 239 locks and dams spanning nearly 12,000 miles. These networks of water channels are used to transport 600 million tons of domestic cargo, generating $405 billion in revenue annually. Nearly 60% of these structures in operation are over 50 years old and have reached design life. A failure of the miter gates could result in a major negative impact on the economy and on the ability to maintain flood control. Administrators need recommendations to better prioritize maintenance and repair of the USACE miter gates. This work investigated the influence of miter gate’s quoin block degradation on load transfer to the pintle and/or pintle connections. Results of finite element analysis are reported for the quoin block degradation simulated levels of 0%, 25%, 50%, and 75%. The parametric study shows the overstressed regions are the pintle neck and bolt-hole regions. To improve pintle designs so they may better mitigate detrimental environmental based deterioration effects, this work recommends (1) increasing the thickness of the bolt-hole connection region and (2) adding ribbing reinforcement around the neck area of the pintle.

Hypothesis and Objectives: We hypothesized that coal combustion products (CCPs), including those created during scrubbing of sulfur dioxide from flue gases, can be used alone or mixed with composted animal manures as effective growth media for plants. Our specific objectives were, therefore, to (1) measure the chemical, physical and hydraulic properties of source materials and prepared mixes, (2) determine the optimum design mix of CCPs and composted animal manures for growth of plants, (3) evaluate the leachate water quality and plant uptake of selected elements from prepared mixes, (4) quantify the interaction between composted animal manures and B concentrations in the mixes, (5) study the availability of P to plants growing in the mixes, and (6) determine the microbial community and siderophores involved in the solubilization of Fe and its transfer to plants. Background: In recent years a major expansion of electricity production by coal combustion has taken place in Israel, the United States and the rest of the world. As a result, a large amount of CCPs are created that include bottom ash, fly ash, flue gas desulfurization (FGD) gypsum and other combustion products. In Israel 100,000 tons of fly ash (10% of total CCPs) are produced each year and in the US a total of 123 million tons of CCPs are produced each year with 71 million tons of fly ash, 18 million tons of bottom ash and 12 million tons of FGD gypsum. Many new scrubbers are being installed and will come on-line in the next 2 to 10 years and this will greatly expand the amount of FGD gypsum. One of the main substrates used in Israel for growth media is volcanic ash (scoria; tuff). The resemblance of bottom coal ash to tuff led us to the assumption that it is possible to substitute tuff with bottom ash. Similarly, bottom ash and FGD gypsum were considered excellent materials for creating growth mixes for agricultural and nursery production uses. In the experiments conducted, bottom ash was studied in Israel and bottom ash, fly ash and FGD gypsum was studied in the US. Major Achievements: In the US, mixes were tested that combine bottom ash, organic amendments (i.e. composts) and FGD gypsum and the best mixes supported growth of tomato, wheat and marigolds that were equal to or better than two commercial mixes used as a positive control. Plants grown on bottom ash in Israel also performed very well and microelements and radionuclides analyses conducted on plants grown on bottom coal ash proved it is safe to ingest the edible organs of these plants. According to these findings, approval to use bottom coal ash for growing vegetables and fruits was issued by the Israeli Ministry of Health. Implications: Bottom coal ash is a suitable substitute for volcanic ash (scoria; tuff) obtained from the Golan Heights as a growth medium in Israel. Recycling of bottom coal ash is more environmentally sustainable than mining a nonrenewable resource. The use of mixes containing CCPs was shown feasible for growing plants in the United States and is now being evaluated at a commercial nursery where red sunset maple trees are being grown in a pot-in-pot production system. In addition, because of the large amount of FGD gypsum that will become available, its use for production of agronomic crops is being expanded due to success of this study.

Computer codes have been used by various researchers in modelling viscoelastic formations, with a good degree of success. Serata used a complex rheological model, REM (Rheological Element Model) code, to simulate mine openings [2]. Others, in the U.S. Nuclear Waste Isolation Programme, have evaluated the capability of various codes for the design of nuclear waste repository [3]. Because of the proprietary nature of the above codes, they are not available to mine operators in Canada. Consequently, in 1984, CANMET initiated a research project to develop a numerical modelling package for use in the design of underground potash mine openings. GEOROC is the resultant computer program; it was developed by RE/SPEC Ltd., of Calgary under contract to CANMET. In recent years, computer simulation is playing an increasingly important role in evaluating the short and long term structural stability of underground mine openings, and in ground control studies related to mine design and layout. Such simulations are increasingly being used in the design of underground salt and potash mines. Because of the viscoelastic nature of salt rock formations, simulation models must take into consideration their time dependent properties if they are to correctly predict opening closures, ground stresses, and ground stability based on prescribed failure criteria. This presentation describes the capabilities, limitations and the use of computer code - GEOROC. A case history in which GEOROC is used to simulate a typical room and pillar mining section of a Western Canadian potash mine is provided. Predicted ground behaviour using the code is compared with actual behaviour as determined through field measurements. Results indicate that good correlation exits between predicted and measured ground behaviour, and is an encouragement to greater use of modelling in mine stability studies related to mine design.

Two commercially-available hydrocarbon dew point analyzers, an Ametek� Model 241 CE II and a Michell Condumax II, were provided by JIP participants for testing. An experimental HCDP research apparatus, first designed at Southwest Research Institute to gather reference hydrocarbon dew point data, was modified to test the automated analyzers. Both automated analyzers, along with a Bureau of Mines chilled mirror device serving as a reference, were installed in the apparatus. Gravimetrically-prepared gas blends containing hydrocarbons through decane were used as test gases, and a small warm box was built to keep the test gases above their hydrocarbon dew points at various simulated line pressures.
