Published: October 2019

Abstract
A repeatable preparation method is useful for investigating systematic variations in behavior across a range of soil types (e.g., gradation, plasticity) and test conditions (e.g., stress level, stress history). Existing methods for preparation of laboratory specimens can be generally categorized into those for cohesionless and cohesive soils, thereby focusing on a narrow range of soils and test conditions. The applicability of these conventional preparation techniques for soils with intermediate (or transitional) properties and behaviors are relatively unknown. In this study, a range of intermediate soils that are not amenable to traditional sand-like or claylike characterization are prepared using a slurry deposition technique and evaluated in oedemetric consolidation, undrained monotonic triaxial shear, and both undrained monotonic and undrained cyclic direct simple shear by three researchers at two separate universities. Results indicate that the slurry technique developed herein can produce uniform mixtures of nonplastic, low-plasticity, and high-plasticity soils, with repeatable behaviors obtained from singular mixtures for all test methods. Evaluation of specimen response across this range of soils exhibits systematic trends of increasing compressibility with increasing plasticity and a transition from dilative to contractive tendencies with increasing soil plasticity. Collectively, these results for synthetic mixtures of silica silt and kaolin clay suggest that the slurry deposition technique is applicable to fine-grained, intermediate soils across a range of plasticity from nonplastic to high-plasticity soils.

Abstract
Management of melanoma has been revolutionized by the use of immune checkpoint inhibitors. Immune system changes associated with aging may affect the efficacy of immune-based therapies. Using the National Cancer Database, we evaluated the impact of age on the receipt and efficacy of modern immunotherapies in patients with metastatic melanoma. We identified 11,944 patients from 2011–2015, of whom 25% received immunotherapy. Older (≥60 years), compared with younger, patients were less likely to receive immunotherapy (odds ratio, 0.69; 95% confidence interval [CI], 0.61–0.78; p &lt; .001). Immunotherapy was associated with a survival benefit in both younger and older patients (&lt;60 years: hazard ratio [HR], 0.64; 95% CI, 0.57–0.72; p &lt; .001; ≥60 years: HR, 0.55; 95% CI, 0.50–0.60; p &lt; .001). Importantly, there was a statistically significant interaction between age and survival with immunotherapy, where a greater benefit was observed for older patients (pinteraction = 0.013). Further work studying the age-related response to immunotherapy is warranted.
Long‐Term Earthquake Hazard in North China Estimated from a Modern Catalog
Authors: Xiong Ziyao , Zhuang Jiancang , Zhou Shiyong 
Published: October 2019

AbstractIn this study, to obtain optimal estimates of the earthquake hazard in North China based on the modern earthquake catalog, we used two variable kernel function estimation methods, proposed by Stock and Smith, and Zhuang, the Bayesian Delaunay tessellation smoothing method by Ogata (ODTB), and a newly proposed incomplete centroidal Voronoi tessellation (ICVT) method, to calculate the total and background seismic spatial occurrence rates for the study area. The sophisticated ODTB method is more stable than the others, but is relatively expensive, in terms of computation demands, whereas Zhuang et al.’s kernel estimate and the new ICVT method are able to provide reasonable estimates and easier to implement. We also calculated the spatial variations of the b‐value, using the Bayesian method with smoothness prior proposed by Ogata. Using comparative analyses and simulation experiments, we show that all of the methods give similar spatial patterns of seismic occurrences.
Beta-3 Receptor Agonists
Authors: Bachus Erasmus , Ponikowski Piotr 
Published: October 2019

Beta-3 adrenergic receptors (β3-AR) have a more widespread tissue distribution in the human body as compared to beta1- and beta2 (β1/2)-adrenergic receptors, including in the bladder, brain, adipose tissue and cardiovascular system. Thus, β3- AR are potential drug targets for a wide range of therapeutic areas, both cardiovascular and non-cardiovascular including overactive bladder (OAB), depression, metabolic syndrome, obesity and heart failure (HF). β3-AR agonists that are selective to the β3-AR include CL 316,243, amibegron (SR58611A), mirabegron (YM-178) and vibegron (RVT-901). However, in HF, study results regarding a possible inotropic effect of β3-AR agonists remain equivocal and some authors report a negative inotropic effect in HF and β3-AR antagonists are also under study.

A chronostratigraphic framework for the Upper Jurassic Morrison Formation, western U.S.A.
Authors: Maidment Susannah C.R. , Muxworthy Adrian 
Published: October 2019

ABSTRACTThe fluvial, overbank, and lacustrine deposits of the Upper Jurassic Morrison Formation of the Western Interior, U.S.A. have been intensively studied due to their diverse and well-preserved dinosaurian fauna, and the presence of economic quantities of uranium and vanadium ores. The formation crops out over 12 degrees of latitude and 1.2 million km2, and is an excellent case study for the examination of paleoecology, community structure, and evolutionary dynamics at a time in Earth's history when the climate was significantly warmer than today. However, paleoecological studies have been hampered by lack of correlation across the formation. Assuming a primarily tectonic control on fluvial architecture, we propose the first chronostratigraphic framework of the formation, which is based on sequence stratigraphy, magnetostratigraphy, and radiometric dating. The formation can be divided into three sequences each represented by a period of degradation followed by aggradation. This chronostratigraphic framework indicates that the formation youngs to the north, and was deposited over about 7 million years during the late Kimmeridgian and Tithonian. This framework provides a foundation for future sedimentological, stratigraphic, and paleobiological studies of the iconic dinosaurian fauna known from the Morrison.

To ensure safe operation of buildings and structures from reinforced concrete, European norms set requirements for its fatigue strength (resistance). Tests are carried out with oscillation swing amplitude 2sa from 150–200 MPa. Rebar shall withstand from 1 to 2 mln. cycles.The analysis of causes which decrease the fatigue strength of cold-formed steel is made in the article. Fatigue strength is a lot affected by surface defects and stress concentrators. Filler transition in the point where transversal rib crosses a rebar body becomes as a rebar stress concentrator. To detect details of early breakage, analysis the condition of fracture in the area of thickened (marking) ribs was made. Sequence of rebar breakage was established as well as the initial point of a crack creation was detected. This fracture is characterized as a fatigue one, with clear zones of fatigue fracture having fine-grained surface and static fracture zone– the rest of section with fibrous structure. While applying a bar mark, smoothness of filler transition was disturbed in the crossing point where transversal rib crosses a rebar body, and this action caused decrease of fatigue strength of cold-formed rebar.The article describes research on development of requirements for rolling tools used in production of cold-formed rebars.Use of information given in this article during design, purchasing and manufacture of the equipment will allow to minimize factors which have negative influence on rebar’s fatigue test results.

Published: October 2019

The possibility of application of the double finishing drawing die at the stage of fine-drawing in the manufacture of steel metal cord 2x0 30SHT is сontemplated. As a result of the performed studies, a numerical finite element model of wire drawing in a serial finishing single fiber and in an experimental double finishing fiber has been developed. The obtained distribution of effective plastic deformation in the wire during drawing shows that when drawing in a double fiber, there is a higher uniformity of deformation in the direction of the radius of the wire along the cross section located at the outlet of the die. The distribution of effective stresses in the wire when drawing shows that when drawing in a double fiber, there is a more uniform distribution of effective stresses in the direction of the radius of the wire along the cross section located at the outlet of the die.Further experimental tests performed at the drawing mill NT 12.4 in StPC-1 showed that the use of double dies allowed to increase the plastic properties of the wire 0.30 SHT, manifested in technological tests by increasing the number of reversible twists of the wire from 7 to 78 and reducing the ratio of yield strength to tensile strength decreased from 95 to 91.

Published: October 2019

The chemical and grain-size analysis of zinc dust – waste of hot – dip zinc plating were made. The research results showed that zinc dust is a dispersed waste with particles of mainly circular shape and sizes from 3 to 200 microns, and in chemical composition it mainly meets the requirements of ISO 3549. The presence of lead in the zinc dust composition, which is slightly higher than the acceptable level will be taken into account in the development of zinc-rich paints compositions. Analysis of the results of sieving of zinc dust showed that it contains particles of size £15 µm, which is about 27% of its fractional composition and which can be recommended for the manufacture of zinc-rich paints.

Naturally Occurring Asbestos in Valmalenco (Central Alps, Northern Italy): From Quarries and Mines to Stream Sediments
Authors: Cavallo Alessandro , Petriglieri Jasmine Rita 
Published: October 2019

ABSTRACT
The Valmalenco area (central Alps, northern Italy) is an excellent case study for naturally occurring asbestos (NOA) because of the huge outcrops of serpentinites and widespread quarrying and mining activities. Extensive sampling of rocks, soils, stream sediments, and airborne asbestos has been in progress since 2004. The combined use of scanning electron microscopy and transmission electron microscopy has proven to be effective for the correct discrimination between asbestiform and non-asbestiform mineralogical varieties (but falling into the World Health Organization fiber definition), whereas phase contrast microscopy has not proven suitable because of the very small size of fibrils after strong mechanical fragmentation. The quantitative analysis of “massive” samples (rocks, soils, and sediments) requires accurate and representative sampling as well as specific counting and discrimination criteria to determine NOA. Over a decade of experience has allowed us to identify critical issues and adopt effective preventive measures.

ABSTRACT
The Republic of Korea Government has adopted a whole-of-government approach in the management of naturally occurring asbestos (NOA) through a nationwide asbestos management plan. Regional and detailed mapping, and examination of NOA effects are still ongoing for NOA management by indoor air, noise and asbestos management division, Ministry of Environment. Plans by the Korea Rail Network Authority are under way to rebuild the Janghang double-track railway. The proposed Jannghang double-track railway route is through an area of high NOA probability that has serpentine and ultramafic rock. Chrysotile, tremolite, and actinolite asbestos were among the rocks identified within the project site (initial planning line and the operational design line). The level of asbestos in most soils was low (≤0.25 percent), while some soils contained 0.75 percent asbestos. Monitoring and analyses of air quality revealed below 0.01 fibers per cm3 (f/cc). However, there were no traces of asbestos detected in the groundwater and stream water. Despite the low asbestos content of the soil and rock, the disturbance of NOA-containing soils and rocks during railway construction could trigger the release of asbestos fibers into the air. NOA mitigation plans and measures are necessary for workers and residents during the construction of the railway.

Abstract
X field was discovered in 2001 and started producing in 2003. The formation is limestone supported with large aquifer. Main challenge is that wells must be produced with critical rate limitation, if a well is produced too hard, water coning and water breakthrough can occur, then oil production will disappear, as happened in one of X's well. In 2011, several wells were becomes ceased-to-flow due to an increase in watercut value, then pumping units were installed on these wells. However, due to recurrent mechanical downhole problems which limit effective production days, a new initiative is required to overcome these issues. After thorough analysis, ESP was chosen as best-fit artificial lift considering its versatility in deviated wells and high deliverability. In 2017, pilot phase of ESP implementation started in X-D4 well, which gave 150 BOPD average oil gain. Learning from the success of X-D4, comprehensive production strategy using ESP is considered crucial for optimum recovery.
To support this strategy, an integrated optimization study with reservoir simulation model was used instead of analytical method to obtain more reliable production forecast. History matching was carried out from initial production data in 2003, a good match in liquid-oil-water-pressure data was successfully obtained, but poor match was occurred on gas production rate, this was ignored due to high uncertainty on gas measurements. The outcomes of simulation study were ESP well candidates, optimum production rate target and proper timing of ESP installation. The next step was the preparation of ESP which consists of the design and procurement of ESP. Following the ESP installation plan, it was also decided to increase power generation capacity at current surface facilities.
Currently, 7 out of 10 ESPs have been installed. Power plant upgrading and overhead line installation to support ESP have also been carried out. The average oil gain obtained was 700 BOPD with cumulative of 160 MBO (from 2017 – until 2018). This optimization case will contribute 1.5 MMBO additional reserve from "do nothing" case. Economic evaluation shows a very good viability with significant additional gross revenue.
This optimization project has succeeded in reducing oil deferment from ceased-to-flow wells and extending the field's life. Good collaboration between each part (subsurface and surface) in this project has succeeded in producing significant oil gains. Continuous monitoring is still needed to further match optimization forecast with actual conditions. Long-term plans, some improvements are still needed in the reservoir model, one of which is OOIP value, there is a possibility that the actual X OOIP is bigger than the one in the reservoir model.
