Obstructive sleep apnea (OSA) is much common and associated with worse clinical outcomes in patients with hypertrophic cardiomyopathy (HCM), however, the diagnosis of OSA in HCM is still insufficient. We aim to investigate the clinical predictors of OSA in a large series of patients with HCM. A total of 589 patients with HCM who underwent sleep evaluations were retrospectively enrolled. Data from clinical characteristics and polysomnography studies were recorded. OSA was present in 346 patients (58.7%). Patients who had OSA were older, more likely to be male and had more clinical comorbidities such as hypertension, atrial fibrillation and cardiac remodeling. Multivariate logistic analyses showed that male, age, body mass index, hypertension and left ventricular outflow tract obstruction were significant factors associated with OSA. The area under the ROC curve (AUC) was 0.78 (95% CI 0.74–0.82; P < 0.001). These factors were also able to identify moderate to severe OSA with an AUC of 0.77 (95% CI 0.73–0.81; P < 0.001). These findings suggest that identifying HCM patients with high risk for OSA is feasible using characteristics from clinical practices and clinicians should have no hesitate to conduct sleep test in these patients.

16S rRNA gene amplicon sequencing is a popular approach for studying microbiomes. However, some basic concepts have still not been investigated comprehensively. We studied the occurrence of spurious sequences using defined microbial communities based on data either from the literature or generated in three sequencing facilities and analyzed via both operational taxonomic units (OTUs) and amplicon sequence variants (ASVs) approaches. OTU clustering and singleton removal, a commonly used approach, delivered approximately 50% (mock communities) to 80% (gnotobiotic mice) spurious taxa. The fraction of spurious taxa was generally lower based on ASV analysis, but varied depending on the gene region targeted and the barcoding system used. A relative abundance of 0.25% was found as an effective threshold below which the analysis of spurious taxa can be prevented to a large extent in both OTU- and ASV-based analysis approaches. Using this cutoff improved the reproducibility of analysis, i.e., variation in richness estimates was reduced by 38% compared with singleton filtering using six human fecal samples across seven sequencing runs. Beta-diversity analysis of human fecal communities was markedly affected by both the filtering strategy and the type of phylogenetic distances used for comparison, highlighting the importance of carefully analyzing data before drawing conclusions on microbiome changes. In summary, handling of artifact sequences during bioinformatic processing of 16S rRNA gene amplicon data requires careful attention to avoid the generation of misleading findings. We propose the concept of effective richness to facilitate the comparison of alpha-diversity across studies.

Learning and Retention of Novel Words in Musicians and Nonmusicians
Authors: Stewart Elizabeth C. , Pittman Andrea L.
Published: June 2021

Purpose

The purpose of this study was to determine whether long-term musical training enhances the ability to perceive and learn new auditory information. Listeners with extensive musical experience were expected to detect, learn, and retain novel words more effectively than participants without musical training. Advantages of musical training were expected to be greater for words learned in multitalker babble compared to quiet.

Method

Participants consisted of 20 young adult musicians and 20 age-matched nonmusicians, all with normal hearing. In addition to completing word recognition and nonword detection tasks, each participant learned 10 novel words in a rapid word-learning paradigm. All tasks were completed in quiet and in multitalker babble. Next-day retention of the learned words was examined in isolation (recall) and in the context of continuous discourse (detection). Performance was compared across groups and listening conditions.

Results

Performance was significantly poorer in babble than in quiet on word recognition and nonword detection, but not on word learning, learned-word recall, or learned-word detection. No differences were observed between groups (musicians vs. nonmusicians) on any of the tasks.

Conclusions

For young normal-hearing adults, auditory experience resulting from long-term music training did not enhance their learning of new auditory information in either favorable (quiet) or unfavorable (babble) listening conditions. This suggests that the formation of semantic and musical representations in memory may be supported by the same underlying auditory processes, such that musical training is simply an extension of an auditory expertise that both musicians and nonmusicians possess.

Published: June 2021

Purpose

Our aim was to assess the different voice prostheses (VPs) to identify the most efficient, safest, patient-tailored, longest lifetime, and inexpensive VPs and assess the different factors affecting their quality.

Method

In September 2017, 15 databases were searched to include all randomized controlled trials. A new search was done in May 2019 to include all other study design articles, which include all the new-era VPs subtypes. Network meta-analysis (NMA) was applied to all 27 outcomes, besides NMA overall and partial order setting was done by using Hasse scatter plots.pvalues were used in NMA, where the best VPs are approaching one and the least approaches zero. Meta-analysis was done for the rest of the outcomes.

Results

Two hundred one articles were eligible for inclusion in our study (N= 11,918). Provox-2 was significantly the most efficient and safest device concerning the most patient preference (odds ratio [OR] = 33.88 [0.65, 1762.24];p= .92), the least dislodgement (risk ratio [RR] = 0.27 [0.13, 0.57];p= .79), the least airflow resistance (RR = 0.42 [0.08, 2.11];p= .84), the least granulation formation (RR = 0.73 [0.02, 26.32];p= .60), and the least VPs' inaccurate size (RR = 0.77 (0.23, 2.61);p= .66). Heat and moisture exchanger addition showed a significant increase in maximum phonation time and breathing experience, withpvalues (1 and .59), respectively. While heat and moisture exchanger addition showed a significant decline in stoma cleaning frequency, coughing frequency, forced expectoration, sputum production, sleeping problems, and loosening of adhesive, withpvalues (.99, .72, .69, .96, 1, and 0.96), respectively, Groningen low resistance and Nijdam were considered the worst devices with both overall meanpvalue of .44.

Conclusions

Provox-2 is considered the best choice as being the most preferable for patients, with the least airflow resistance, dislodgment, granulation formation, and prosthesis inaccurate size. Groningen low resistance and Nijdam were considered the worst devices according to our analysis.

Context. It is thought that ultraluminous X-ray sources (ULXs) are mainly powered by super-Eddington accreting neutron stars or black holes as shown by the recent discovery of X-ray pulsations and relativistic winds.

Aims. This work presents a follow-up study of the spectral evolution over two decades of the pulsing ULX NGC 1313 X-2 in order to understand the structure of the accretion disc. The primary objective is to determine the shape and nature of the dominant spectral components by investigating their variability with the changes in the source luminosity.

Methods. We performed a spectral analysis over the canonical 0.3–10.0 keV energy band of all the high signal-to-noise XMM-Newton observations (96% of the available data), and we tested a number of different spectral models, which should approximate super-Eddington accretion discs. The baseline model consists of two thermal blackbody components with different temperatures plus an exponential cutoff powerlaw.

Results. The baseline model provides a good description of the X-ray spectra. In particular, the hotter and brighter (LX ∼ 6–9 × 1039 erg s−1) thermal component describes the emission from the super-Eddington inner disc and the cutoff powerlaw describes the contribution from the accretion column of the neutron star. Instead, the cooler component describes the emission from the outer region of the disc close to the spherisation radius and the wind. The luminosity-temperature relation for the cool component follows a negative trend, which is not consistent with L ∝ T4, as is expected from a sub-Eddington thin disc of Shakura-Sunayev. This is not consistent with L ∝ T2 either, as is expected for an advection-dominated disc. However, this would rather agree with a wind-dominated X-ray emitting region. Instead, the (Lx, Tdisk) relation for the hotter component is somewhere in between the first two theoretical scenarios.

Conclusions. Our findings agree with the super-Eddington scenario and provide further detail on the disc structure. The source spectral evolution is qualitatively similar to that seen in NGC 1313 X-1 and Holmberg IX X-1, indicating a common structure and evolution among archetypal ULXs.

Context. The recent launch of Solar Orbiter and the flyby of BepiColombo opened a brief window during which these two spacecraft, along with the existing spacecraft at L1, were positioned in a constellation that allowed for the detailed sampling of any Earth-directed coronal mass ejection (CME). Fortunately, two such events occurred during this time period with in situ detections of an interplanetary coronal mass ejection (ICME) by Solar Orbiter on the 2020 April 19 and 2020 May 28. These two events were subsequently observed in situ by BepiColombo and Wind as well around a day later.

Aims. We attempt to reconstruct the observed in situ magnetic field measurements for all three spacecraft simultaneously using an empirical magnetic flux rope model. This allows us to test the validity of our flux rope model on a larger and more global scale. It additionally allows for cross-validation of the analysis with different spacecraft combinations. Finally, we can also compare the results from the in situ modeling to remote observations obtained from the STEREO-A heliospheric imagers, which were able to capture the interplanetary evolution of the coronal mass ejections.

Methods. We made use of the 3D coronal rope ejection model (3DCORE) in order to simulate the ICME evolution and reconstruct the measured flux rope signatures at the spacecraft positions. For this purpose, we adapted a previously developed approximate Bayesian Computation sequential Monte-Carlo (ABC-SMC) fitting algorithm for the application to multi-point scenarios. This approach not only allows us to find global solutions, within the limits of our model, but to also naturally generate error estimates on the model parameters and detect potential ambiguities.

Results. We show that we are able to generally reconstruct the flux rope signatures at three different spacecraft positions simultaneously by using our model in combination with the flux rope fitting algorithm. For the well-behaved April 19 ICME, our approach works very well and displays only minor deficiencies. The May 28 ICME, on the other hand, shows the limitations of our approach for less clear ICME measurements or strongly deformed shapes. Unfortunately, the usage of multi-point observations for these events does not appear to solve inherent issues, such as the estimation of the magnetic field twist or flux rope aspect-ratios due to the specific constellation of the spacecraft positions, which all lie near the ecliptic plane. As our general approach can be used for any fast-forward simulation based model, we give a blueprint for future studies using more advanced ICME models.
Mining Engineer Competencies for an Innovative Economy

Published: June 2021

One of the features of modern mining is its focus on the development of human resources. The high level of labor productivity, as the main factor in the efficiency of mining enterprises in the context of heightened competition in the mineral resources market, brings to the fore the assessment of the state of human potential and its use with maximum efficiency. Consequently, the successful operations of a mining enterprise largely depend on how effectively its human potential is used. To achieve high results of work, a competently built personnel policy is required, one of the key tasks of which is the selection and placement of personnel. As practice shows, the shortage of qualified mining engineers and the growth of their cost in the labor market can become one of the key factors hindering the development of business in the field of mining.

Authors: Kuporova Alexsandra , Belyakov Vladimir
Published: June 2021

The article The article examines the possibility of extracting sod fuel peat to replace imported coal. A possible raw material base is considered for producing molded solid peat-based fuel in permafrost conditions. The production of molded peat products in the form of sod peat is proposed as an option. The experimental work on drying sod peat shows that peat can be extracted and dried to standard moisture content in the conditions of northern Yakutia. A flowsheet of producing sod peat from lake peat by hydraulicking is presented. According to the flowsheet the peat mass is loosened, liquefied by lake water, sucked in by a dredger pump and pumped through a pulp pipeline to the shore, where it is dewatered in geotubes to the molding water content. After dewatering, the geotubes are cut and the peat mass is loaded into a peat spreader mixing the peat, forming it into cylindrical pieces, and spreading it on a drying field. When molded, the peat structure is modified chemically to obtain strong and durable products. Having reached sufficient strength, peat sods are piled in a stack supplied with a trench for artificial ventilation at its base. The peat is dried to a final moisture content of 24–30%.

Published: June 2021

At present, the complex nature of the impact on the ecosystem in regions with intensive mining creates a multidimensional information “plume” consisting of data on mineral reserves, the state of mining operations, accumulated, current and future environmental pollution. The transition to the lean use of the subsoil and the reasonable disposal of mining waste requires fundamentally new forms of environmental information accumulation and processing during designing new enterprises and regulating the activities of existing ones. The most promising form of information support for the greening of mining is a geoportal. It is a complex of software and technological support for working with spatial data. Its key task is to provide the users with tools and services for storing and cataloging, publishing and loading spatial and environmental data, searching and filtering by metadata, interactive web visualization, direct access to geodata based on map web services.

Problems of improving the quality of life of miners in mining regions on the example of the Kemerovo region (Kuzbass) and ways to solve them
Authors: Batievsky Veronika , Sokolovsky Mikhail , Moroz Elena
Published: June 2021

The quality of life is an integral indicator that includes the following indicators: the level of health of the population, education, employment, poverty, spending and consumption, life expectancy at birth, and so on. There are economic, social, ecological and climatic, political and cultural criteria for the quality of life. The problem of ensuring the proper level and quality of life of miners in mining regions is considered on the example of the Kemerovo region (Kuzbass). Unfavorable production factors in coal mining include meteorological conditions, pollution of the mine atmosphere with harmful gases, the release of coal dust during any technological processes, dust formation, lack of sunlight, noise and vibration, high risk of injury; difficult water supply and sanitation. These factors contribute to the formation of occupational diseases, which leads to a decrease in the quality of life. It is necessary to develop a set of measures to eliminate the identified problems: structural changes in the industry, the development of coal-technical, coal-chemical and energy-coal clusters, improving the consumer properties of coal products to expand sales markets, the formation of new professional standards and improving the system of training and advanced training of personnel, the introduction of unified systems of industrial and environmental safety.

Published: June 2021

The article deals with the ecological and economic aspects of the spread of helminthiasis in the coal region on the example of the Kemerovo region - Kuzbass. The authors note that the dominant component of environmental damage in coal-mining regions includes not only the industrial development, but also the negative impact of human activity as an anthropogenic factor of the biosystem. Based on the integrative approach of interaction between medicine, economics, and ecology, the authors developed and proposed practical measures to reduce the spread of helminthiasis in Kuzbass, which can not only effectively solve this problem, but also become the basic concept of the modern style of ecological thinking on a global scale. The paper proves the thesis that for the effective functioning of subjects of the Russian Federation with a single-industry focus, such as Kuzbass, it is necessary to form an ecological and economic mechanism that ensures the sustainable development of mining regions of the Russian Federation in changing external and internal conditions that determine the functioning of not only the mineral resource complex of mining regions, but also their socioeconomic development.

Ultimately, the goal of economic development is to improve the quality and standard of living of the population. Today, this integral indicator is determined not only by economic parameters, but also by a number of other components, among which an important role is assigned to environmental ones. In this regard, theoretical and practical studies of reproduction systems come to the fore, which make it possible to guarantee economic growth with the preservation of natural and ecological potential in the face of aggravation of global problems of mankind. The issue of choosing a new model of economic development has been actualized for Russia, in particular, by the policy of sanctions and a reduction in export revenues. The circular economy fully meets all these pressing issues of our time, ensuring a reduction in the dependence of economic growth on the resource intensity of production and consumption, contributing to the economic and environmental development of Russian regions, while reducing the level of environmental pollution. This is especially true for regions which economy is based on mining. The article analyzes the economic and environmental factors influencing the formation and development of a closed-cycle economy as one of the new forms of management that ultimately contribute to the sustainable development of regions.

Stimulating Environmental Investments in the “Green” Economy of Eurasia
Authors: Kazitskaya Nina , Prusova Vera , Bochkov Sergey
Published: June 2021

To date, investment in industrial production and infrastructure has passed through a certain bifurcation point associated with the division into “green” (environmental) and traditional (resource and nature-intensive) investments. Following the new demands of modern society to improve the environment and reduce the pressure on it from industry, the concept of traditional economic growth based on extensive environmental management is being replaced by ideas of sustainable development related to resource conservation, waste recycling and reduction of polluting emissions into the biosphere. As a result, investment as the basis of economic growth is also gravitating towards a green economy, participation in which is gradually becoming a major competitive advantage for the markets of developed countries. In this process, the role of the state in stimulating nature-saving investments, in which indirect instruments (subsidies, tax incentives), take an increasing place, is growing many times over.
Formation of Technological Platforms in Mining Regions as a Tool for the Implementation of the National Technology Initiative (on the Example of the Kemerovo Region, Krasnoyarsk Territory and the Republic of Tatarstan)
Authors: Shavina Evgeniya
Published: June 2021

At present, it is important for national economies to adapt to the emerging conditions of volatility. One of the main trends in the modern world is the transition to a new technological order. Therefore, it is important to build the economic system of any state on the basis of current trends. Taking into account the potential of the fuel and energy complex of the Russian Federation as a whole, and of its individual regions in particular, it is advisable to renew such sub-industries as the extractive industry. Modernization based on the use of new technologies in such a large sector of the economy has significant prospects in the context of the implementation of the National Technology Initiative. One of the tools contributing to innovative development is the formation of technology platforms. Regions can show different rates of involvement in the process of technological renewal due to the different level of the formed scientific and technical base and resource potential. Nevertheless, the centralized concentration of innovations, scientific resources and modern infrastructure are designed to have a positive impact on the subjects, regardless of the degree of influence of internal factors.

Published: June 2021

The paper analyzes the dynamics of socio-economic indicators of the development of coal-mining regions of Russia. The aim of the study is to analyze the socio-economic situation of coal-mining regions and determine the factors that influenced the social processes in the region. Based on statistical data for the period from 2010 to 2019, there was conducted the analysis of changes in economic indicators such as: income of the population; gross regional product per capita; nominal average monthly wage; unemployment rate; the proportion of the population with incomes below the subsistence level; housing commissioning in the regions. Analysis of the data showed that the most favorable social position of all the analyzed coal-mining regions is observed in the Sakhalin region. The “outsiders” in terms of social status among the coal-mining regions are the Trans-Baikal Territory and the Kemerovo Region. Improvement of the social situation in coal-mining regions is associated with the adoption by the Russian Government of a program to combat poverty, an increase in social payments to certain categories of citizens, an indexation of old-age pensions, etc. It was also revealed that social processes in the regions are influenced by prices for hydrocarbons on the world market and objective economic phenomena such as business cycles.

Published: June 2021

This paper aims at providing a synthetic (semantic, social, cultural, historic) survey on the names used for the tourist and catering business entities in Kuzbass, with an attempt to discover the reason for naming trends in the region. Naming is one of the most ubiquitous and important activities in business sphere, pursuing a number of goals: (1) identifying and promoting the brand / image of a business entity; (2) making sure the business will function well because its name is alluring for clients, or the name is targeted efficiently; (3) the name renders the values and ideology of the company. Linguistically, the main ways to produce business or brand names are the following: abbreviations, shortenings and/or blends, associations, allusions / associations, rhyming, transonimization (using proper names of real or imaginary people for business names), using foreign words, significant numbers, quotations / allusions / alliterations / mythological elements. “Traditional” naming may exploit ancient elements (old-fashioned and outdated words, spelling, grammar, etc.). Naming in Kuzbass in tourist sphere does not rely heavily on mining concept, but rather exploits its regional exotics and a competitive differentiator. Recreational tourism in its naming promotes the concept of vast taiga spaces and pristine Siberian nature.

Epimysial Transposition Flap: A Novel Technique for Coverage of Exposed Tendon after Tissue Transfer
Authors: Lombana Nicholas F. , Falola Reuben A. , Scott Michael , Saint-Cyr Michel H.
Published: June 2021

Background The radial forearm flap (RFF) is a versatile flap that can be used for soft-tissue coverage or as a source of vascularized bone during reconstruction. A problem that can arise after RFF harvest is tendon exposure in the donor site, which may lead to tendon injury and restriction of the hand and wrist’s range of motion. Many different methods for providing adequate tendon coverage in the donor site after RFF harvest have been reported. We present a novel technique for coverage of exposed tendon in the volar forearm with an epimysial transposition flap and a split-thickness skin graft (STSG).

Methods Retrospective review of two cases: one salvage case with exposed tendon after harvesting an RFF and another with exposed volar forearm tendon after traumatic injuries. Variables of interest were post-operative STSG integration and hand/wrist range of motion.

Results Both cases demonstrated 100% graft take at 5-week follow-up. No decrease in hand/wrist range of motion in the patient that could undergo testing.

Conclusion We introduce two cases for coverage of exposed flexor tendon in the volar forearm with an epimysial transposition flap. This can be used as a salvage operation for coverage of exposed tendon or as an acute method of tendon coverage prior to skin grafting. In both cases, the skin graft had excellent incorporation.
Should We Suture Arthroscopic Portals? Effects on Intra-articular Fluid Retention
Authors: Sargin Serdar , Atik Aziz , Aslan Ahmet
Published: June 2021

Knee arthroscopy is one of the most common surgical procedures in orthopaedics and especially in sports medicine. Portal problems and effusion after knee arthroscopy have been reported. The fluid retention within the joint in knee arthroscopy can affect clinical outcomes, but there is no consensus on portal management. The studies of portal management in knee arthroscopy have mainly addressed wound healing and cosmetic problems. There is insufficient information in the literature about whether the irrigation fluid used in this effusion contributes to the process. This study investigates whether arthroscopic irrigation fluid is retained in the joint and whether portal-closure management has an effect on effusion. In this randomized, prospective study, 91 patients (46 [50.5%] sutured-portal group and 45 [49.5%] open-portal group) were included. Suprapatellar knee-diameter measurement and the number of times the dressing was changed were used to assess intra-articular fluid collection. The visual analog scale (VAS) score, Oxford knee score, and Knee Society score were used to evaluate knee problems. All portal wounds in both groups healed without any problems. Superficial or deep infection was not observed in either group. There was no statistically significant difference in VAS score, Oxford knee scores, and Knee Society scores between groups. Although there was a decrease in the knee diameter of both groups between the early postoperative period and first postoperative day, a statistically significant difference in knee diameter was found, especially in the open-portal group. There was a significant difference between the groups in terms of the number of dressings used in the first 24 hours after surgery. Leaving portals open may be effective in preventing intra-articular fluid retention. We thus advise leaving the arthroscopy portals open with just a simple dressing for selected patients.

Implications of thin laminations on pore structure of marine shale reservoir: Goldwyer Formation case study from Western Australia
Authors: Iqbal Muhammad Atif , Rezaee Reza , Smith Gregory , Mandal Partha Pratim
Published: June 2021

The pore structure of a shale reservoir is a major control on hydrocarbon potential, yet shale pore systems are complex and affected by various
factors. This paper focuses on the differences in pore structure between thinly laminated and massive black shale (MBSh) beds in the Ordovician Goldwyer-III shale, Canning Basin, Western Australia. A multiscale approach
included image logs, core descriptions, thin sections, scanning electron microscope and X-ray diffraction analysis with low-pressure nitrogen and carbon dioxide gas adsorption tests. The results indicate that the Goldwyer shale comprises laminated beds of quartz silt and shale with thin beds
of organic-rich clay, plus minor interbedded carbonate bands or concretions. The pore types are subjected to rock type, and the thinly laminated shale (LSh) is enriched in intergranular and intragranular pores. In contrast, the MBSh mainly comprises organic matter pores. The LSh is slightly enriched in mesopores but has negligible micropores. The mesopores are wedge-shaped and associated with an inorganic matrix of clay and pyrite. In
comparison, the MBSh contains both mesopores and micropores. These pores are slit-like and related to organic matter and clay. The clay content and total organic carbon fluctuations control the development of mesopores and micropores in both the laminated and MBSh beds in the Goldwyer-III shale. The MBSh layers are suggested as the most important rock types for fluid flow via pore systems due to higher total pore volume, specific surface area and gas adsorption capacity.

Natural or native molecular hydrogen (H2) can be a major component in natural gas, and yet its role in the global energy sector’s usage as a clean energy carrier is not normally considered. Here, we update the scarce reporting of hydrogen in Australian natural gas with new compositional and isotopic analyses of H2 undertaken at Geoscience Australia. The dataset involves ~1000 natural gas samples from 470 wells in both sedimentary and non-sedimentary basins with reservoir rocks ranging in age from the Neoarchean to Cenozoic. Pathways to H2 formation can involve either organic matter intermediates and its association with biogenic natural gas or chemical synthesis and its presence in abiogenic natural gas. The latter reaction pathway generally leads to H2-rich (>10mol% H2) gas in non-sedimentary rocks. Abiogenic H2 petroleum systems are described within concepts of source–migration–reservoir–seal but exploration approaches are different to biogenic natural gas. Rates of abiogenic H2 generation are governed by the availability of specific rock types and different mineral catalysts, and through chemical reactions and radiolysis of accessible water. Hydrogen can be differently trapped compared to hydrocarbon gases; for example, pore space can be created in fractured basement during abiogenic reactions, and clay minerals and evaporites can act as effective adsorbents, traps and seals. Underground storage of H2 within evaporites (specifically halite) and in depleted petroleum reservoirs will also have a role to play in the commercial exploitation of H2. Estimated H2 production rates mainly from water radiolysis in mafic–ultramafic and granitic rocks and serpentinisation of ultramafic–mafic rocks gives a H2 inferred resource potential between ~1.6 and ~58MMm3 year−1 for onshore Australia down to a depth of 1km. The prediction and subsequent identification of subsurface H2 that can be exploited remains enigmatic and awaits robust exploration guidelines and targeted drilling for proof of concept.
CO2-EOR+ in Australia: achieving low-emissions oil and unlocking residual oil resources
Authors: Tenthorey Eric , Taggart Ian , Kalinowski Aleksandra , McKenna Jason
Published: June 2021

The petroleum industry, through the production and consumption of oil and gas, contributes to global greenhouse gas emissions. However, the industry’s leadership and experience in underground injection and storage of CO2, especially through CO2 enhanced oil recovery (CO2-EOR), which has been proposed as a possible solution to reducing atmospheric CO2 levels, has not been well acknowledged. Unlike traditional CO2-EOR, which tends to be a net carbon emitter due to the use of predominantly natural CO2, rather than anthropogenic, CO2-EOR+ focuses on storing a larger volume of CO2. Thus CO2-EOR+ not only provides a potential solution to dispose of anthropogenic emissions but at the same time reduces reliance on imported oil through increased domestic production. Increased industry interest and energy policy strategies directed at reducing and/or removing emissions from industry processes reflect the growing social and economic impetus to improve operation practices and the petroleum industry’s reputation. Residual oil zones (ROZs) below identified oil–water contacts provide an excellent target for the application of CO2-EOR+. They offer a producible residual oil resource accessible through CO2-EOR, as well as a large pore volume for CO2 storage, with efforts focused on converting ROZs into resources and reserves. Existing fields in the Surat and Cooper-Eromanga Basins are already well placed to utilise anthropogenic CO2 sources to achieve conventional CO2-EOR metrics. The ROZs in these basins will hopefully allow potential EOR projects to increase the CO2 volumes stored, per incremental barrel of oil, well past traditional levels (0.2–0.3 tCO2/bbl), and in doing so, potentially achieve net negative-emission oil.
Characterising the application of horizontal wells and indirect hydraulic fracturing for improved coal seam gas drainage
Authors: Johnson Raymond L. , Cheong Sharon , Farley Andrew
Published: June 2021

Historically, horizontal wells in coal seam gas (CSG) producing areas of Australia have been limited in their ability to stimulate horizontal wellbores with hydraulic fractures, despite most basins being in favourable stress states capable of generating multiple transverse hydraulic fractures. In some cases, overlapping mining tenements limit the ability to effectively deploy steel casing completions to effectively manage multi-stage fracture stimulations along the lateral. In other cases, potential wellbore instabilities preclude the placement of laterals with adequate length to stage numerous fractures required to make a well economic. Strike Energy’s Jaws 1 well indicated well instability when drilling horizontally in the Patchawarra Vu Coal Seam in Petroleum Exploration Licence 96 of the Weena Trough in the Cooper Basin. To overcome this instability, Strike Energy introduced the application of an innovative process of deploying multiple, indirect hydraulic fractures in Jaws 1ST from a horizontal wellbore underlying the coal. Microseismic and surface deformation tiltmeter data acquired during the treatment confirmed the successful placement of fractures in the Patchawarra Vu Coal Seam. Further, chemical tracing and production testing provide further insight into the placement and effectiveness of the overall stimulation. Through analyses of data from the Jaws 1ST, we provide insight and recommendations regarding horizontal well placement to improve indirect hydraulic fracture effectiveness. These recommendations would be applicable for other Australian CSG basins where direct horizontal well drilling and fracture stimulation has been limited (e.g. overlapping mining tenements) or where horizontal well instabilities limit drilling within the seam (i.e. Cooper Basin, depleted coals).
Cultural Conceptualization of Tamil Hindu Marriages
Authors: Shanmuganathan Thilagavathi
Published: June 2021

This study investigates the cultural conceptualization of marriage among Tamil Hindu communities in
Australia and Malaysia. The Hindu cultural schema of marriage relates to the physical, social and spiritual aspects, and
language acts as the central aspect of the cultural cognition of the community. Data is based on a variety of sources,
particularly focus group discussions, translated verses from Hindu Holy Scriptures (Vedanta), and personal interviews. Findings
show various cultural schemas entrenched within the marriage schema, particularly Vedic Astrology, Sacred Invocation and
Blessings, which are shared knowledge among community members. The cultural schema of marriage (or vivaha) that
is instantiated in the Vedanta considers marriage a religious obligation (Dharma). It is during social interactions that
the cultural metaphors associated with marriage are discussed. marriage as a thousand-year crop and marriage as a
journey are metaphorical expressions that illustrate the traditional worldview of the Tamil Hindu community.

Characterizing four-body indistinguishability via symmetries
Authors: Minke Alexander M , Buchleitner Andreas , Dittel Christoph
Published: June 2021

We show how to characterize the indistinguishability of up to four identical, bosonic or fermionic particles, which are rendered partially distinguishable through their internal degrees of freedom prepared in mixed states. This is accomplished via their counting statistics when subjected to a highly symmetric unitary acting upon their external (i.e. dynamical) degrees of freedom. For pure internal states, we further extract information on the particles’ collective phases, which ultimately allows for an experimental reconstruction of the full many-particle density operator up to complex conjugation.
The Influence of a Heterogeneous Surface on the Free Volume Oscillations of an Oblate Gas Bubble
Authors: Alabuzhev A A
Published: June 2021

The natural oscillations of a cylindrical gas bubble surrounded by an incompressible fluid with free interface are considered. The bubble has an equilibrium cylindrical shape and is bounded axially by two parallel solid surfaces. Dynamics of contact lines is taken into account by an effective boundary condition: velocity of the contact line is assumed to be proportional to contact angle deviation from the equilibrium value. The equilibrium contact angle is right. Different Hocking parameters determine individual damping rates, but dissipation in the integral system is determined by their total contribution. The frequency of the volume (breathing) harmonic of free oscillations can vanish in a certain interval of the values of the Hocking parameter for homogeneous plate surface. However, Surface inhomogeneity destroys this monotonic damping effect.
