Проведен анализ тенденций развития камер сгорания энергетических газотурбинных установок большой и средней мощности передовых производителей, идущих по пути существенного повышения КПД установок, увеличения топливной гибкости при сохранении экологических требований. Продемонстрирован опыт создания малоэмиссионных камер сгорания (МЭКС) во Всероссийском теплотехническом институте. Приведены результаты испытаний МЭКС ГТ-16П в одногорелочном отсеке при полных параметрах. Показана ее доработка до двузонной, что позволило существенно расширить границы устойчивого малоэмиссионного горения в широком диапазоне температур наружного воздуха. При допустимых значениях NOx удалось достичь температуру газов на выходе из камеры сгорания 1700 °C. Проанализированы конструкции горелочных устройств МЭКС газотурбинных установок, позволяющие избежать основных проблем, возникающих при сжигании топлива с большим содержанием водорода, а именно: проскока пламени в зону предварительного перемешивания, высоких потерь давления на горелках и неустойчивости процесса горения. Показано, что данные конструкции не содержат лопаточного завихрителя и выраженной зоны предварительного перемешивания.
This paper presents an analysis of trends in the development of combustion chambers for high- and medium-power gas turbine power units of advanced manufacturers pursuing a significant increase in the efficiency of the plants and fuel flexibility while maintaining environmental requirements. The experience in developing low-emission combustion chamber (LECC) in the All-Russian Thermal Engineering Institute is presented. The results of tests of the GT-16P LECC in a single-burner compartment with full parameters are presented. Its modification to a dual-zone configuration is shown, which made it possible to significantly extend the range of stable low-emission combustion over a wide temperature range of outside air. For acceptable values of NOx, it was possible to reach a combustor exhaust gas temperature of 1700 °C. An analysis is made of the designs of gas turbine LECC burners allowing to avoid the main problems arising when burning fuel with a high content of hydrogen: flame breakthrough into the premixing zone, high pressure losses on burners, and combustion instability. It is shown that these designs do not contain a blade swirler and a pronounced premixing zone.

Образование оксидов азота при горении угля или биотоплива из связанного с топливом азота остается важной экологической проблемой. В качестве простейшей модельной системы для описания горения угля можно использовать молекулу пиридина, которая, с одной стороны, имеет ароматическую структуру, а с другой - содержит в своем составе атом азота. Данная работа посвящена теоретическому изучению путей реакции взаимодействия пара-пиридила с молекулярным кислородом. Была построена поверхность потенциальной энергии взаимодействия пара-пиридила с молекулярным кислородом. Радикал пара-пиридил безбарьерно присоединяет молекулу кислорода с образованием радикала PyOO, далее реакция может пойти по трем путям, приводя к четырем возможным продуктам: 3H-пиррол, HCO + HCN, 1λ2-пиррол и 1λ3,4-оксазин.
The formation of nitrogen oxides during combustion of coal or biofuel containing fuel-coupled nitrogen is an important environmental problem. As the simplest model system used to describe coal combustion, one can use a pyridyl molecule, which, on the one hand, has an aromatic structure and, on the other hand, contains a nitrogen atom in its structure. This paper describes a theoretical study of the reaction of para-pyridyl interaction with molecular oxygen. A surface of potential energy interaction of para-pyridyl interaction with molecular oxygen is constructed. The para-pyridyl radical barrierlessly attaches an oxygen molecule with formation of the PyOO radical, and then the reaction can follow one of three paths, leading to four possible products: 3H-pyrrole, HCO + HCN, 1λ2-pyrrole, and 1λ3,4-oxazine.
Palms behind the Smog: Strange Energies in Mawsim al-hijra ilā al-shimāl (Season of Migration to the North)
Authors: Olszok Charis 
Published: July 2024

AbstractThis essay argues for the primacy of energy as an impetus in the writing of the Sudanese author al-Tayyib Salih. Taking his most famous novel, موسم الهجرة إلى الشمال (1966; Mawsim al-hijra ilā al-shimāl; Season of Migration to the North), as a case study, it explores the significance of climatic factors and of changes to energy regimes in the novel's plot, characterization, intertextuality, and postcolonial critique. Through the character of Mustafa Saʿid, it argues for a posthuman impulse in the novel, as Mustafa uncannily transforms from Faustian archetype to a fantastical, nonhuman force. It concludes by shifting to alternative forms of energy within Salih's writing, as the spiritual energy of the Sufi “unseen” meets the unheeding world of atoms, supercharged with new energies in the modern era.
Sexual Violence and Racial Capitalism: James Baldwin's Prisons, 1969–74
Authors: Dango Michael 
Published: July 2024

AbstractThis essay engages with James Baldwin's work on prison rape in the early 1970s: his directing of John Herbert's play Fortune and Men's Eyes while in Turkey (1969–70), his nonfiction book No Name in the Street (1972), and his penultimate novel, If Beale Street Could Talk (1974). Over the course of these works, Baldwin theorized that sexual violence constitutes racial capitalism by mediating between the two state-organized institutions tasked with securing the primitive accumulation and surplus value on which racial capitalism relies: the family (and, more broadly, heterosexuality) and the prison (and, more broadly, policing). In turn, Baldwin helps converge two intellectual traditions that developed after him, the black radical and Marxist feminist traditions, in order to explain how sexual violence expropriates both forced productive labor and unpaid reproductive labor through its production of racialized gender and kinlessness.

Job opportunities for graduates of the French Language Studies Program (PS) are currently more and more promising. But of course, graduates must have good or even superior skills to compete with graduates of the same field from various Indonesian universities. Therefore, the existence of specialization courses (MK) is a very good step to equip graduates with qualified skills, especially in the field of French. Specialized courts can help graduates be able to compete in a wider range of professions. Employment opportunities for graduates will be increasingly open. But in reality, there are still students, alumni and stakeholders who don't know and understand this. Thus, through this service activity, it is hoped that the various parties directly involved will be able to learn about the importance of the specialized tribunal during studies in the French Language Studies Program. Not only the provision of French with a literary and pedagogical basis, but also competence in the field of specialized French (FOS / French for Specific Objectives) to be able to compete in an increasingly difficult professional world. The challenges of the disruptive era and the 4.0 industrial revolution and the 5.0 society require students and alumni as well as stakeholders to be able to adapt quickly to the changes taking place both in the world of education than professionals.

Impact of the Earthquake Rupture on Ground-Motion Variability of the 24 August 2016 Mw 6.2 Amatrice, Italy, Earthquake

ABSTRACT
The devastating 24 August 2016 Mw 6.2 earthquake that struck Amatrice, Italy, marked the beginning of a prolonged seismic sequence dominated by three subsequent Mw ≥6.0 events in the central Apennines region. The earthquake destroyed Amatrice’s historic center, claiming the lives of 299 individuals and causing widespread damage in the neighboring villages. The severity of the ground shaking, with a recorded maximum acceleration of 850  cm/s2 on the east–west component at the Amatrice station, was far greater than the predicted acceleration based on the Italian ground-motion model (GMM). As pointed out by several investigations, the observed ground-motion amplitude and its spatial variability during the earthquake can be linked to specific rupture characteristics, including slip distribution and rupture directivity effects revealed by the observed data (Tinti et al., 2016; Pischiutta et al., 2021). In this study, we conducted physics-based 3D numerical simulations of ground motion for the Amatrice earthquake for frequencies up to 3 Hz. We employed a series of kinematic rupture models and a well-constrained local 3D velocity model incorporating surface topography. The kinematic rupture realizations were generated using multiscale hybrid and fully stochastic models, following the technique proposed by Graves and Pitarka (2016). We focused on assessing the sensitivity of near-fault ground-motion amplitudes to earthquake rupture characteristics, in particular, the spatial slip pattern. To evaluate the quality of our simulations, we employed goodness-of-fit measurements performed in comparisons of simulated and recorded ground motions. The simulated ground motions compare well with the recorded data and predictions from GMMs for Italy, ITA18 (Lanzano et al., 2019). However, we found that the simulated interevent ground-motion variability (randomness in the source process) of peak ground velocity, σ (PGV) is higher than the constant σ (PGV) predicted by conventional GMMs. Our simulations using several rupture scenarios demonstrate that the near-fault ground-motion amplification pattern is directly related to the slip distribution pattern.

Aim. To study the relationship and predictive value of integral metabolic indices of obesity in the identification of ectopic obesity.Material and methods. The study included 326 patients (146 men and 180 women, mean age 61±9 years). Anthropometric data, degree of obesity, body mass index (BMI), waist circumference (WC), sagittal abdominal diameter (SAD), body obesity index (BAI), visceral obesity index (VAI), lipid accumulation index (LAP), triglycerides-glucose index (TyG) was assessed. Perivascular adipose tissue (PVAT) volume, pericardial adipose tissue (PAT) volume and thickness of perirenal fat tissue (PRF) were assessed with CT.Results. Patients were divided into groups: with isolated ectopic obesity (iEO) (n=17); with isolated abdominal obesity (iAO) (n=74); with EO variants: pericardial (PCO) (n=31), perivascular (PVO) (n=22) or perirenal (PRO) (n=33) with AO; with mixed ectopic obesity and AO (mEO+AO) (n=117), and patients without obesity (n=32). Significantly higher BMI, WC, SAD, and BAI indices were found in individuals with PCO+AO, PRO+AO and mEO+AO. The highest values of LAP were found in groups: PCO+AO, PVO+AO, PRO+AO. There was a correlation between ectopic fat depots and WC (r=0,62 for PAT, r=0,55 for PVAT and r=0,39 for PRF, p=0,01) and SAD (0,429, 0,329 and 0,435, respectively, p=0,01). Correlation was established between PAT, PRF and LAP (0,425 and 0,319, respectively, p=0,01). The highest AUC values>0,8 had models of WC and SAD in identification of PCO (0,801 and 0,801, respectively) and PRO (0,826 and 0,826, respectively). For PCO, the cut-off point of WC was 100,5 cm (specificity 72,9%, sensitivity 70,2%, p=0,000), SAD — 25 cm (specificity 73%, sensitivity 70,2%, p=0,000). For PRO, the cut-off of WC was 101 cm (specificity 71,4%, sensitivity 72,7%, p=0,000), SAD — 25 cm (specificity 71,4%, sensitivity 72,7%, p=0,000).Conclusion. Еctopic fat depots are related to the risk of metabolic disorders. Potential informative value of simple and accessible integral metabolic indices was established. WC>100,5 cm, SAD>25 cm may indicate to the presence of PCO; WC>101 cm, SAD>25 cm — to the presence of PRO.

Published: July 2024

Case:
A 59-year-old woman presented with progressively worsening neck pain and radicular symptoms. Cervical radiographs revealed C1-C2 dynamic instability. Magnetic resonance imaging and computed tomographic angiogram revealed an anomalous right vertebral artery with intracanal trajectory at C1. A unilateral left C1-C2 fusion with a C1 lateral mass screw and C2 transarticular screw placement was performed due to the anomalous artery. At 14-month follow-up, the patient's cervical symptoms had resolved.

Conclusion:
In this patient with an aberrant vertebral artery who was indicated for C1-C2 fusion, a unilateral contralateral fusion with a C1 lateral mass screw and C2 transarticular screw was a satisfactory treatment option.

Published: July 2024

Case:
We report a 15-year-old adolescent boy being followed up for 6 years with osteogenesis imperfecta (OI). Genetic testing of this child revealed a novel missense variant c.925C>T p.Arg309Cys in the CREB3L1 gene. Treatment with regular pamidronate therapy showed increased bone mineral density and a reduced fracture rate. His lower limb rush rodding improved his mobility. His withdrawal from bisphosphonate therapy worsened his mobility status but started improving after he restarted treatment, suggesting a response to pamidronate therapy.

Conclusion:
We report a novel biallelic missense variant c.925C>T, p.Arg309Cys, in the CREB3L1 gene causing OI, which responded to bisphosphonate therapy and corrective surgery.
Life Cycle Optimization of CO2 Huff ’n’ Puff in Shale Oil Reservoir Coupling Carbon Tax and Embedded Discrete Fracture Model
Authors: Pan Guangxuan , Wang Sen , Xu Jianchun , Feng Qihong 
Published: July 2024

Summary
Amidst escalating environmental pressures, energy-intensive industries, particularly the oil and gas sector, are compelled to transition toward sustainable and low-carbon operations, adhering to the constraints of the environmental economy. While conventional reservoirs have been extensively developed, unconventional reservoirs, such as shale reservoirs, are poised to be the focal point in the future. Carbon dioxide enhanced oil recovery (CO2-EOR), a potent development tool proven effective in shale reservoirs, offers substantial carbon storage potential while significantly augmenting production. However, prior studies have solely optimized shale oil CO2-EOR production based on a singular optimization algorithm with net present value (NPV) as the objective function. In this study, we propose a novel NPV concept incorporating a carbon tax, which incorporates carbon taxes regulated by governments or organizations, thereby guiding carbon offsetting in oil reservoirs. We employ the embedded discrete fracture model (EDFM) approach to strike a balance between the accuracy of shale reservoir fracture simulation and computational efficiency, thereby enhancing timely technical guidance in the field. Subsequently, we compare the existing mainstream reservoir optimization algorithms and introduce a novel life cycle CO2 huff ’n’ puff (HnP) optimization workflow based on low-carbon NPV. The optimized NPV of the target reservoir witnessed an increase of 116.30%, while the optimization time was reduced by 89.47%, and the CO2 storage capacity was augmented by 12.58%. The workflow accelerates the simulation of the CO2 HnP in shale reservoirs, optimizing the production efficiency and CO2 storage capacity of shale reservoirs, and facilitating comprehensive and efficient production guidance for the production site.
