Актуальность исследования обусловлена необходимостью познания фундаментальной научной проблемы – железомарганцевый рудогенез Мирового океана. Помимо перспективного минерального сырья морские железомарганцевые образования являются регистраторами условий седиментации в прошлом. Их формирование осуществляется при различных процессах, которые отражены в вещественном и изотопном составе. В настоящее время наименее изученным регионом Тихого океана является его северный сегмент. Цель: изучить изотопный состав Sr и Nd железомарганцевых корок северной Пацифики, формирующихся в условиях низкого терригенного потока. Методы: литолого-морфогенетический; рентгеноструктурный – определение минерального состава; масс- спектрометрический – определение химического и изотопного состава. Результаты. Исследованы железомарганцевые образования гайотов северной части Императорского хребта (Детройт, Сьюзей, Ханзей) и разломных зон Амлия, Рат и Стейдмейт, а также гайота Вулканолог (Магеллановы горы) в качестве сравнительного материала. На основании текстурно-структурных и минералого-геохимических особенностей изученные железомарганцевые образования отнесены к гидрогенным железомарганцевым коркам. Изотопный состав стронция изученных образцов находится в интервале от 0,70797 до 0,70919 (среднее 0,70885). При этом содержание стронция изменяется почти в три раза – от 660 до 1700 г/т. Зависимости изотопного состава от концентрации Sr не отмечается. Смещение величины отношения 87Sr/86Sr происходит к его значениям, характерным для вулканических пород, что является отражением высокого количества кварц-плагиоклазовой примеси в образце. Изотопный состав неодима в пересчете на εNd варьирует в интервале от –3,5 до –3,0, что соответствует современному значению глубинной воды северной Пацифики. Повышение значение εNd до –2,3 соответствует пробе с максимальной аллотигенной примесью. Минимальное значение величины εNd (–4,4) установлено в подошвенном слое железомарганцевой корки гайота Ханзей. Такое значение соответствует миоценовой глубинной воде северной Пацифики. Это является основанием полагать, что в миоцене на формирование вещественного состава железомарганцевых корок северной Пацифики оказывали влияние глубинные атлантические воды, поступающие через Панамский пролив. Прекращение их поставки в Тихий океан произошло, вероятно, пять млн лет назад.

Актуальность исследования определяется необходимостью оценки региональных особенностей транспорта и преобразования органического вещества в различных седиментационных и биогеохимических обстановках, действующих на Восточно-Сибирском арктическом шельфе, в том числе в Восточно-Сибирском море – наиболее ледовитом и наименее изученном море Российской Арктики. Цель исследования заключается в определении состава и источников органического вещества донных осадков Чаунской губы (Восточно-Сибирское море). Объекты: 25 проб поверхностных донных осадков, отобранных по профилю от прибрежной зоны Чаунской губы до внутренней части шельфа Восточно-Сибирского моря в ходе комплексной научно-исследовательской морской экспедиции на борту НИС «Академик Опарин» в сентябре–октябре 2020 г. Методы. Для анализа групп углеводородных соединений ОВ донных осадков был применен пиролитический анализ по методу Rock-Eval; оценка распределения н-алканов проводилась на основе результатов газовой хромато-масс-спектрометрии. Гранулометрический анализ осадков выполнялся на лазерном анализаторе частиц. Результаты. Состав осадочного материала в Чаунской губе преимущественно определяется особенностями подводного рельефа и гравитационными потоками поступающего терригенного материала – продуктов локальной термоабразии береговой зоны (о. Айон) и речного аллювия в юго-восточной части губы. Определенную роль в формировании седиментационного облика губы, предположительно, играют процессы вытаивания криозоля в результате разрушения областей припайного льда. Данные пиролиза и анализ распределения н-алканов для поверхностных осадков указывают на смешанный генезис органического вещества в поверхностных осадках с доминирующим вкладом наземного органического вещества высокой степени преобразованности и высокое содержание трудноразлагаемых гуминовых веществ и фульвокислот. Присутствие автохтонного органического вещества отражает высокую продуктивность вод Чаунской губы.

Published: February 2023

The quickest and easiest way to avoid greenhouse gas (GHG) emissions is to purchase renewable electricity and offset the remaining emissions. However, the industrial sector’s electricity needs already exceed renewable electricity generation. Moreover, electricity accounts for only one third of the industry’s energy needs. Simultaneously, the advance of sectoral coupling and the decarbonisation of industrial processes, as well as the desire to rapidly decrease dependence on fossil fuels, are creating significant additional demand for renewable energy. Neither existing nor planned generation and transmission infrastructure will suffice to meet the expected short-term demand. Based on survey data from the German Industry Energy Efficiency Index, this article therefore examines the share of GHG savings that companies intend to achieve on- and off-site. Understanding how much additional generation and transmission capacity is needed by the industry to decarbonise and by when is crucial to identify and address the extent of excess demand. On average, companies plan to avoid 22 % of their 2019 emissions by 2025 and 27 % by 2030, primarily through on-site measures. In combination with the extrapolation of the entire industry’s needs for off-site capacity, the data calls for a rapid expansion of planning authority and green generation capacities.

Selama komunikasi teknologi terus berkembang, keamanan informasi menjadi sangat penting karena kejahatan di dunia maya semakin marak terjadi. Untuk meningkatkan keamanan informasi, pada penelitian ini dikonstruksi penggabungan kriptografi secret sharing scheme (t, w) dengan steganografi audio least significant bit (LSB). Kriptografi secret sharing scheme merupakan kriptografi modern yang mampu mencegah terjadinya situasi informasi terpusat karena tidak memerlukan kunci untuk enkripsi. Selain itu, metode ini juga menyulitkan peretas dalam merekonstruksi pesan karena sulitnya mengumpulkan minimal share. Implementasi dari penggabungan tersebut, dihasilkan suatu prototype program menggunakan bahasa pemrograman Python 3.10 dengan skema (3,4). Media cover steganografi yang digunakan adalah audio, dan pesan yang dapat diolah program adalah PIN angka enam digit dengan digit pertama tidak nol. Hasil yang diperoleh dari program enkripsi dan embedding adalah 4 buah audio-share yang terdengar sama dengan audio yang asli, sehingga keberadaan informasi di dalam audio sulit diketahui. Hasil pada program dekripsi dan extracting adalah PIN yang dapat dikonstruksi kembali.

Background:
National projections of future joint arthroplasties are useful for understanding the changing burden of surgery and related outcomes on the health system. The aim of this study is to update the literature by producing Medicare projections for primary total joint arthroplasty (TJA) procedures until 2040 and 2060.

Methods:
The present study used data from the Centers for Medicare & Medicaid Services (CMS) Medicare/Medicaid Part B National Summary and combined procedure counts with use of Current Procedural Terminology (CPT) codes to identify whether the procedure was a primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) procedure. In 2019, the annual volume of primary TKA was 480,958 and that of primary THA was 262,369. These values formed a baseline from which we generated point forecasts for 2020-2060 and 95% forecast intervals (FIs).

Results:
Between 2000 and 2019, the estimated annual volume of THA increased by 177% and that of TKA increased by 156% on average. Regression analysis projected an annual growth rate of 5.2% for THA and 4.44% for TKA. Based on these yearly projected increases, an estimated increase of 28.84% and 24.28% is expected for each 5-year period after 2020 for THA and TKA, respectively. By 2040, the number of THAs is projected to be 719,364 (95% FI, 624,766 to 828,286) and the number of TKA is projected to be 1,222,988 (95% FI, 988,714 to 1,512,772). By 2060, the number of THAs is projected to be 1,982,099 (95% FI, 1,624,215 to 2,418,839) and the number of TKAs is projected to be 2,917,959 (95% FI, 2,160,951 to 3,940,156). In 2019, Medicare data showed that THA constituted approximately 35% of TJA procedures performed.

Conclusions:
Based on 2019 total volume counts, our model forecasts an increase in THA procedures of 176% by 2040 and 659% by 2060. The estimated increase for TKA is projected to be 139% by 2040 and 469% by 2060. An accurate projection of future primary TJA procedure demands is important in order to understand future health-care utilization and surgeon demand. This finding is only applicable to a Medicare population and demands further analysis to see if this extends to other population groups.

THE INFLUENCE OF BASEL III ON ISLAMIC BANK RISK
Authors: Ding Xiaoling , Haron Razali , Hasan Aznan 
Published: February 2023

This paper investigates the impact of bank regulatory capital on Islamic bank risk using bank-level data from 29 countries and covering the period from 2004 to 2020. Applying the Generalized Method of Moments technique for dynamic panels, we discover that, on average, Islamic bank regulatory capital ratios exceed the level required by Basel III. Our findings provide evidence in support of the Moral Hazard Hypothesis; that is, there is a negative relationship between capital and risk. These findings indicate that Islamic banks are better protected against risk when they fulfil Basel III and IFSB regulatory capital requirements. According to our findings, authorities that aim to improve the financial stability of the banking industry should reinforce their policies and oblige banks to adhere to regulatory capital requirements during a crisis, such as COVID-19. Finally, we observe that different risk indicators have diverse correlations with regulatory capital, and our findings are robust across a variety of estimation methodologies.
AQUARIA-BASED OBSERVATIONS OF THE OPHIUROIDOPHIOLEPIS SUPERBAAND THE TRACKWAYS IT PRODUCES

Published: February 2023

ABSTRACTAn array of trace fossils have been ascribed to brittle-star behaviors including locomotion traces such as Biformites. Brittle-star locomotion has been well described but little work has been done to link modern brittle-star behavior to the trace fossil record. To draw this connection, a brittle star was kept in an aquarium and isolated in a “walking” tank with a fine glass-bead substrate. The animal was left in the walking tank for 30 minutes then the substrate was examined for traces. A digital camera was used to record the animal's movements and to document the resulting traces. Photographs were processed with photogrammetry software to produce digital models in order to acquire high-resolution images. Walking traces were described in detail and two morphologies were identified, which correspond with the ‘rowing' and ‘reverse-rowing' modes of brittle-star locomotion. Interestingly, traces similar to Biformites were not formed although some Biformites characters are observed. Morphological similarities include elongated lobate depressions and bioglyphs. Trackway dissimilarities include a repeating, paired, symmetrical pattern observed in the lab contrasting with Biformites that is often expressed as a texture of dense and overlapping, or isolated imprints. Another dissimilarity is the expression of bioglyphs in the lab as striae compared to the positive protuberances observed in Biformites. This study illustrates the utility of using actualistic observations to: (1) refine interpretations of locomotory mechanisms, such as rowing and reverse rowing, for a better understanding of walking behavior, and (2) to expand recognition criteria for ophiuroid (and other taxa) tracks in the fossil record.
Technology Focus: Mature Fields and Well Revitalization (January 2023)
Authors: Jain Siddarth 
Published: February 2023

Capitalizing on untapped potential and quantifying risk is the key to success in a turbulent commodity industry. Mature fields have seen it all. Periods of high oil price have invited increased investment and pushed boundaries, while low-oil-price periods have had a severe effect on the fields’ sustainability and development. Mature fields have existed through a time of great technological change and stand on the cusp of their ultimate fate—either to maximize recovery with the lowest possible expenditures amid tightening environmental regulations or to close the taps and prepare for painful abandonments. In a capital-intensive industry, mistakes often are unforgiving and the costs of uncertainty and error are great.
Fluctuating technological, political, and business influences add to the volatility and risk in selecting the next big idea for mature fields. The framework and success of future opportunities is reliant on the data used to quantify them, and this is something of which all mature fields have plenty. As they have delivered value throughout their life, the uncertainty associated with them reduces, and the new ideas discussed here come to light.
Alternative use of wells for geothermal energy generation, carbon sequestration in depleted reservoirs, and the use of machine learning to maximize recovery are solutions that provide insight into how diverse the scope of mature field rejuvenation ideas can be. These solutions have something in common, however; they aim to capitalize on data, modularize problems, and structure a sustainable solution. These solutions are scalable, upgradable, and, most importantly, cost-effective for large and small operators. The upstream sector has long valued efficiency and accuracy. Small improvements in mature fields can make a significant economic difference with an established infrastructure in place. Value in large mature fields still exists, but one has to know where to look and what lenses to use.

Development of a qualitative data analysis codebook informed by the i-PARIHS framework
Authors: Ritchie Mona J , Drummond Karen L. , Smith Brandy N. , Sullivan Jennifer L. , Landes Sara J. 
Published: February 2023

Abstract
Background: The integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, and its predecessor PARIHS, have been widely utilized in implementations studies. Although i-PARIHS developers have focused on creating tools to guide facilitators in its application in practice, tools are also needed for evaluation and research. Codebooks with clear and meaningful code labels and definitions are an important component of qualitative data analysis and have been developed for other widely used frameworks. There is no such codebook for i-PARIHS. Additionally, sub-constructs for the Innovation, Recipients, and Context constructs lack definitions and there is no sub-classification of facilitation activities for the Facilitation construct. The lack of a standardized codebook hinders our ability to synthesize research findings across studies, explore and test the range of activities that are utilized in facilitation efforts, and potentially validate and further refine i-PARIHS. This paper describes a rigorous process of developing a detailed qualitative codebook informed by the i-PARIHS framework.Methods: A workgroup of qualitative researchers conducted a rigorous four-phase process to develop a codebook informed by i-PARIHS. In phase 1, workgroup members reviewed and discussed literature, consulted an organizational scientist, and drafted and refined subcodes and definitions for i-PARIHS constructs. In phase 2, they obtained feedback from an expert panel and further refined subcodes and definitions. In phase 3, they obtained feedback from i-PARIHS developers/experts and incorporated it into the codebook. Finally, two studies piloted application of the codebook which informed the final version.Results: The resulting i-PARIHS-informed codebook includes definitions for the four main constructs of the framework: Innovation, Recipients, Context, and Facilitation; subcodes and definitions for characteristics of each of these constructs; and instructions for the suggested application of individual codes and use of the codebook generally.Conclusions: The standardized codes and definitions in the codebook can facilitate data exploration, pattern identification, and insight development informed by the i-PARIHS framework. Qualitative analysts can also use them to explore interactions between i-PARIHS constructs, maximize the potential for comparing findings across studies, and support the refinement of the i-PARIHS framework using empirical findings from multiple studies.
