description: UK Industrial Fusion Solutions Ltd is paving the pathway for a commercial magnetically-confined fusion power plant, known as the Spherical Tokamak for Energy Production (STEP), with the ambition of building a STEP Prototypic Powerplant (SPP) by 2040. The design of such a power cycle poses the following key challenges: 1) high power cycle conversion efficiency to overcome large plant parasitic loads, 2) integration of different heat sources at multiple temperature levels from the tokamak in-vessel components, including low temperature heat sources, 3) high power cycle operational flexibility, and 4) high reliability and plant life for the intermittent pulse mode of operation during the initial phases of the SPP. Closed-loop CO2 power cycles show promise in realising high efficiency (>550 °C); efficient integration of low-grade heat by capitalizing on the enthalpy gap due to the real gas effect of CO2; and high power density CO2 turbines & compact heat exchangers signifying the potential of realising operational flexibility. This paper compares the thermodynamic performance of three novel CO2 cycle configurations, namely 1) transcritical CO2 cycle variant; 2) supercritical CO2 cycle variant; and 3) transcritical CO2 blend based power cycle variant (using SO2 as the dopant), to efficiently integrate four different heat sources at different temperature levels from the fusion machine, demonstrating the feasibility of using such a power cycle design for SPP.

EXPRESSION OF THE CONCEPT OF MAN AND NATURE IN THE PLOT OF ERKIN SAMANDAR'S WORKS. (ROMAN "BANK THAT LOST ITS RIVER")
Creators: name: Khajibaev, Kishin
Publisher: name: Zenodo
Year: 2025

description: The article notes that the concept of man and nature forms the basis of Erkin Samandar's works, and that one way of depicting the reality of the plot in the novel "The Bank That Lost Its River" is to compare the world of man and nature through two objects. Also, the characters of Buva, Kurban Salaev, for protecting the environment and living creatures, are subjected to tragic conditions by nature's enemies, and as a result, the relationship between nature and humans is broken, which is analyzed based on plot events with perfect construction.

description: We studied the impact of introducing first-year computer science (CS) students to ethical thinking about the social justice impacts of data collection, tracking, bias, internet privacy, and competitive “real world” system design and critique activities. While basic content was consistent for all, one group was involved throughout the course in peer discussions designed to foster greater engagement, with the anticipation that this would enable students to reach new levels of sensitivity through peer-to-peer interaction. This article reports on our observation of this design, interview, and project data collected throughout the course as well interviews conducted eight months later to learn about how students were retaining and applying what they learned. We found that students are sensitive to the technology-related risks and vulnerabilities encountered by individuals based on race, gender, and, to some extent, age, but they struggle to assess who is responsible for these risks, what to do about bias in technology design, and how to mitigate harms for individuals whom they perceive to be vulnerable, furthering the argument for an integrated ethics curriculum. We explore the value of formal peer-led discussion to evolve social justice thinking with a focus on identity, though note that opportunities for any group discussion are meaningful to students’ thinking about social justice. Over the longer term, students tend to recall and apply ethics that is closely related to their identity, suggesting that empathy has limits.

description: Guided by theories and empirical research on intergenerational relationships, we examine the phenomenon of grandparents caring for grandchildren in contemporary China. Using a longitudinal dataset (China Health and Nutrition Survey), we document a high level of structural and functional solidarity in grandparent-grandchildren relationships. Intergenerational solidarity is indicated by a high rate of coresidence between grandchildren and grandparents, a sizable number of skipped-generation households (no parent present), extensive childcare involvement by non-coresidential grandparents, and a large amount of care provided by coresidential grandparents. Multivariate analysis further suggests that grandparents' childcare load is adaptive to familial needs, as reflected by the characteristics of the household, household members and work activities of the mothers.

description: Supercritical Carbon Dioxide (sCO₂) turbines, modeled on traditional axial-flow steam turbine design practices, often rely on empirical loss models developed by experimental campaigns on steam and gas turbines blades with aspect ratio greater than one. This study evaluates the applicability of these models for designing sCO₂ turbines featuring low aspect ratio blades (under 1). A low fidelity modeling tool (zTurbo), originally formulated based on Craig and Cox (CC) and Traupel (TR) loss correlations, was extended by integrating loss models proposed by Kacker Okappu (KO) and Aungier (AG). zTurbo was applied for Mean Line Design (MLD) of a five-stage axial-flow low aspect ratio sCO2 turbine (236.5 bar, 893.2 K inlet; 81 bar outlet). The four MLDs conceived using CC, KO, TR, AG loss models achieved flowpath total-to-total efficiency of 87.5%, 87.5%, 90.8%, and 91.9%. A detailed comparative analysis of four MLDs led to selection of AG loss model coupled with TR tip loss correlation to effectively capture all the losses within sCO2 turbine flowpath. zTurbo was linked with the Non-linear optimization algorithm to generate optimized AG based MLD flowpath exhibiting a total-to-total efficiency of 92.2 %. The optimized AG based MLD was then modeled to form full 3D flowpath, and high fidelity numerical simulations were performed to evaluate the turbine performance and losses encountered along the flowpath. Both modeling approaches showed strong agreement for estimating turbine flowpath total-to-total aerodynamic efficiency, differing by less than 0.1%. A detailed loss analysis comparison between two modeling techniques showed AG loss correlation reliability for estimating profile losses; however it overestimated the secondary losses, highlighting the need for detailed investigation into secondary flow development in sCO₂ turbines featuring low aspect ratio blades.

description: The literature on neighborhoods and health highlights the difficulty of operationalizing “neighborhood” in a conceptually and empirically valid manner. Most studies, however, continue to define neighborhoods using less theoretically relevant boundaries, risking erroneous inferences from poor measurement. We review an innovative methodology to address this problem, called the socio-spatial neighborhood estimation method (SNEM). To estimate neighborhood boundaries, researchers used a theoretically informed combination of qualitative GIS and on-the-ground observations in Texas City, Texas. Using data from a large sample, we assessed the SNEM-generated neighborhood units by comparing intra-class correlation coefficients (ICCs) and multi-level model parameter estimates of SNEM-based measures against those for census block groups and regular grid cells. ICCs and criterion-related validity evidence using SF-36 outcome measures indicate that the SNEM approach to operationalization could improve inferences based on neighborhoods and health research.

description: Compared to conventional technology, power cycles that use supercritical carbon dioxide (sCO2) as working fluid promise more effective energy conversion, very low dimension, and high flexibility, especially at high temperatures. These abilities are very suitable for use with advanced small modular reactors (SMRs). The concept of an SMR based on a fluoride salt (FLiBe) coolant and a sCO2-based conversion cycle, called ‘Energy Well’, is being developed by Centrum výzkumu Řež (CVR). During the research and development of the Energy Well nuclear reactor and long-term activities of CVR in the field of sCO2 technologies, a loop-type experimental facility working with FLiBe was developed, assembled, and operated. The facility was coupled with another unique infrastructure, the sCO2 loop, to support the development of a potential interface between the FLiBe coolant and an innovative conversion cycle fluid (sCO2). This facility intends to test the key components and operational procedures important in the application of similar technologies on a larger scale. The key components of the FLiBe loop are the main circulation pump, the heat exchanger (FLiBe/sCO2) and the electrical heater, which represents the core of a molten salt reactor. All components were developed and assembled by CVR. Some aspects of the design of these components were validated using CFD tools. A description of the first operational experience and experimental data are provided in this paper. The resulting outlet temperatures, heat flux and FLiBe mass flow rate were compared with experimental measurements and the overall heat transfer coefficient was estimated. As part of the experimental campaign, the circulation pump for FLiBe was first tested separately. After this successful test, the experimental FLiBe circuit was connected to the existing sCO2 loop, which is operated by CVR, via the heat exchanger. During the experimental campaign, data were obtained from the operations of both coupled devices, including from the commissioning procedure of the FLiBe circuit and the controlling of the two devices simultaneously. Experimental data were processed and evaluated. Unfortunately, large uncertainties were found in the FLiBe temperature measurements and, consequently, the resulting mass flow rates.

The E&L Magmatic Ni-Cu-(PGE) Deposit, Northwestern British Columbia : Preliminary Sulfide Petrology, Platinum-Group Element Mineralogy and Lead Isotope Systematics
Creators: name: Vandenburg, Eric Douglas James
Publisher: name: The University of British Columbia
Year: 2020

description: The olivine gabbro-hosted E&L magmatic Ni-Cu-(PGE) sulfide deposit is located in the Jurassic Eskay Rift back-arc basin within the Stikine Terrane of northwestern British Columbia and is one of only two known high-grade magmatic Ni-Cu-(PGE) massive sulfide deposits in the Canadian Cordillera. The E&L intrusion is hosted in the 180.7 Ma Nickel Mountain Gabbro Complex and by Upper Hazelton Group pyritic black shales and mudstones. The petrology of sulfide and platinum group minerals and the lead (Pb) isotopic compositions of ore minerals were investigated to provide constraints on mineralization mechanisms and the source of metals in the deposit. The textures of pyrrhotite-pentlandite-chalcopyrite-magnetite are typical of magmatic ore deposits and platinum group minerals are predominantly tellurides and bismuthotellurides. Unusual sieve-textured magnetite in the semi-net-textured sulfides of the Lower Chamber and “pseudo-cuneiform” magnetite in the massive sulfides of the Lower Discovery Zone are interpreted to be the result of disequilibrium-induced resorption. The Pb isotopic compositions of sulfide minerals analyzed directly in thin section by laser ablation- inductively coupled plasma-mass spectrometry (LA-ICP-MS) are variable with many of the results overlapping within analytical uncertainty. Some of the higher temperature sulfides (e.g., pyrrhotite) have relatively unradiogenic Pb isotope compositions, whereas lower temperature minerals (e.g., chalcopyrite) have compositions indicating the effects of crustal contaminant and of secondary hydrothermal alteration. Isotope mixing models suggest that variable degrees of contamination occurred at depth of a mantle-derived magma by the Triassic-Jurassic island-arc basement of Stikinia and at shallower depths by Upper Hazelton Group strata. The similarities in Pb isotopic ratios between E&L sulfides and sulfides from other deposit types in the region highlight the relative isotopic homogeneity of the Stikinia crust during the Early-Middle Jurassic. Combined, trace element and Pb isotopic geochemical variations from the E&L intrusion and deposit are consistent with post-collisional decompression melting of a metasomatized mantle source during the transtensional development of the Eskay Rift, with no genetic relationship to the Nickel Mountain Gabbro Complex. Given the inferred ascent path of the parent magmas along areas of high structural permeability and the lack of upper age constraints on mineralization, there may be a close tectonic relationship between mineralization at the E&L deposit and the nearby Eskay Creek and Anyox volcanogenic massive sulfide (VMS) deposits.

description: Supercritical CO2 (sCO2) can be employed as a working fluid in sCO2 power cycle. Supercritical fluids enhance thermal efficiency and enables compact system designs due to their favorable thermophysical properties. However, the intersection of sCO2 thermophysical properties with the two-phase-like regime leads to a pseudo-boiling phenomenon (PBP). During PBP, a thicker vapor-like layer forms, reducing convective heat transfer efficiency and leading to the heat transfer deterioration (HTD). HTD, closely associated with PBP, significantly affects overall system performance. This study investigates the magnitude of HTD by analyzing the characteristics of the vaporlike layer in a heated tube. A wide range of mass and heat fluxes and pressures (mass fluxes (200kg/(m2s)≤ G ≤800kg/(m2s)), heat fluxes (25kW/m2≤ qw ≤100kW/m2), and pressures (7.5MPa≤ P ≤30MPa)) were simulated in vertical and horizontal tubes with 4 mm inner diameter. Computational fluid dynamic simulations were performed using the Eulerian method and the SST k – ω turbulence model. Additionally, behavior of sCO2 was validated against experimental data in vertical and horizontal tubes with 4 mm inner diameter. The results show that HTD can be ignored beyond 10MPa when the Richardson number is less than 0.01. In other words, this study provides a roadmap for identifying critical HTD thresholds in tube heat exchangers and thermal systems.

description: Stressors are theorized to be associated with higher allostatic load (AL), a concept of physiological wear measured as a composite of physical biomarkers. Risk of high AL may vary by gender and may be intensified in places with significant environmental risks, otherwise known as ‘environmental riskscapes’. Yet, no study has examined the relationship between stressors, gender, and allostatic load in an environmental riskscape. Using primary data collected in a sample (N=1072) exposed to various environmental and social stressors, we find that long-term residence in Texas City (30 or more years), residential proximity to petrochemical plants, perceived poor neighborhood conditions, and daily hassles are associated with higher allostatic load components. Variation in AL differs by gender and the types of biomarkers examined. Gender moderates the effect of length of residence in Texas City on cardiovascular health risk. We discuss our findings in light of current research on stressors, gender, allostatic load, and double jeopardy within environmental riskscapes.

description: Despite the increasing interest in supercritical carbon dioxide (sCO2) cycles in place of Rankine cycles for power generation, there is limited information available on the design and off-design performance of mechanical air-cooled heat rejection systems for sCO2 power cycles. In this work, the conceptual design and thermofluid system modelling of an air-cooled heat exchanger (ACHE) system for a 50 MWe sCO2 CSP plant is presented. The design includes the selection of major components for the ACHE system including the piping, fan, and finned-tube bundle, as well as the development of an in-house thermofluid model of the system using Python. A model of the system was also developed using the commercial code Flownex to simulate off-design conditions. To limit auxiliary power consumption, sCO2 ACHEs require deep finned-tube bundles with forced-draft fans that operate at a relatively high static pressure rise, and a relatively low volume flow rate. The results show that flow bypass combined with fan on-off control is an effective method to maintain a bulk outlet sCO2 temperature. However, to prevent local over-cooling to temperatures below the critical point, fan speed control is required. Additionally, employing fan speed control significantly lowers auxiliary power consumption relative to bypass control.

Alternatives to Aging Alone?: “Kinlessness” and the Importance of Friends Across European Contexts
Creators: name: Mair, Christine A.
Publisher: name: Oxford University Press
Year: 2019

description: Increasing numbers of older adults cross-nationally are without children or partners in later life and therefore likely have greater reliance on nonkin (e.g., friends). This pattern may be particularly pronounced in country contexts that emphasize friendship. This article hypothesizes that those who lack kin (e.g., children, partners) and/or who live in countries with a stronger emphasis on friendship have more friends in their networks. Although these hypothesized patterns are consistent with interdisciplinary literatures, they have not been tested empirically and therefore remain overlooked in current “aging alone” narratives.This study combines individual-level data from the Survey of Health, Ageing, and Retirement in Europe (Wave 6) with nation-level data from the European Values Survey to estimate multilevel negative binomial models exploring number of friends among those aged more than 50 years who lack kin across 17 countries.Older adults who lack kin or whose kin are unavailable report more friends in their networks, particularly in countries with a higher percentage of people who believe that friends are “very important” in life.This article challenges dominating assumptions about “aging alone” that rely heavily on lack of family as an indicator of “alone.” Future studies of “kinlessness” should consider the extent to which friendship is correlated with lack of kin, particularly in more socioeconomically developed countries. Previous research on “aging alone” may have overestimated risk in more privileged countries that already emphasize friendship, but underestimated risk in family-centered countries where “kinlessness” and alternative sources of support are less common.

description: Background: Hospice use has been shown to benefit quality of life for patients with terminal illness and their families, with further evidence of cost savings for Medicare and other payers. While disparities in hospice use by patient diagnosis, race, and region are well documented and attention to the role of family members in end-of-life decision-making is increasing, the influence of spousal characteristics on the decision to use hospice is unknown.Objectives: To determine the association between spousal characteristics and hospice use.Design: We used data from the Health and Retirement Study (HRS), a prospective cohort study, linked to the Dartmouth Atlas of Health Care and Medicare claims.Setting: National study of 1567 decedents who were married or partnered at the time of death (2000–2011).Measures: Hospice use at least 1 day in the last year of life as measured via Medicare claims data. Spousal factors (e.g., education and health status) measured via survey.Results: In multivariate models controlling for patient factors and regional variation, spouses with lower educational attainment than their deceased spouse had decreased likelihood of hospice use (odds ratio [OR]?=?0.58; 95% confidence interval [CI]?=?0.40–0.82). Health of the spouse was not significantly associated with likelihood of decedent hospice use in adjusted models.Implications: Although the health of the surviving spouse was not associated with hospice use, their educational level was a predictor of hospice use. Spousal and family characteristics, including educational attainment, should be examined further in relation to disparities in hospice use. Efforts to increase access to high-quality end-of-life care for individuals with serious illness must also address the needs and concerns of caregivers and family.

description: The purpose of this study is to expand knowledge of care options for aging populations cross-nationally by examining key individual-level and nation-level predictors of European middle-aged and older adults’ preferences for care.Drawing on data from the Survey of Health, Ageing and Retirement in Europe and the Organisation for Economic Co-operation and Development, we analyze old age care preferences of a sample of 6,469 adults aged 50 and older with chronic disease in 14 nations. Using multilevel modeling, we analyze associations between individual-level health care needs and nation-level health care infrastructure and preference for family-based (vs. state-based) personal care.We find that middle-aged and older adults with chronic disease whose health limits their ability to perform paid work, who did not receive personal care from informal sources, and who live in nations with generous long-term care funding are less likely to prefer family-based care and more likely to prefer state-based care.We discuss these findings in light of financial risks in later life and the future role of specialized health support programs, such as long-term care.

description: Supercritical carbon dioxide (sCO2) has shown a high potential in power generation cycles to increase thermal efficiency and decrease the physical footprint. Supercritical CO2 power cycles operate at relatively high temperatures compared to steam and air, necessitating the development of new sealing materials. In this paper, the design challenges, development and preliminary test results of a 500oC, 200 bar sCO2 dry gas seals test rig are presented. The main rig components are pressure control devices (liquid pump and expansion valves), heat exchangers (liquid condenser, gas heaters, and air cooler), and measuring instruments. Various design challenges are identified due to the thermo-physical properties as well as the operating conditions of the sCO2 test rig such as the ice formation during start-up, heat loss to the ambient air, and material compatibility with the various test rig components. A thermodynamic design model has been developed to size the test rig components and estimate the gas conditions across the rig. The model includes tube and valve sizing, heat exchanger design, and thermal insulation models. The initial phase of the test campaign was conducted at Cranfield University (CU) to verify the ability of the test rig to deliver sCO2 at the required conditions and to validate the developed numerical models. The results showed the validity of the proposed setup to supply sCO2 steadily at 500oC and 200 bar at a flow rate of 15 kg/h. The heat exchanger model applied to a finned tube bundle air cooler showed close estimations to the test results with a maximum deviation in the heat capacity of 2.3%. The thermal insulation model including the heating tape showed reasonable predictions for the temperature rise across the heating sections with a maximum deviation from the experimental measurements of 10oC when the temperature rise was around 240oC. The suitability of using rock wool insulation and stainless steel 316 tubes with dry CO2 at 500oC was verified.

Family Ties and Health Cross-Nationally: The Contextualizing Role of Familistic Culture and Public Pension Spending in Europe
Creators: name: Mair, Christine A.
Publisher: name: Oxford University Press
Year: 2013

description: Although previous research theorizes that cross-national variation in the relationship between family ties and health is due to nation-level differences in culture and policy/economics, no study has examined this theorization empirically.Using data from the Survey of Health, Ageing, and Retirement in Europe (SHARE) and the Organization for Economic Co-operation and Development (OECD), this study uses multilevel modeling to analyze individual-, nation-, and cross-level effects for 30,291 older adults in 14 nations.Family ties to spouses/partners and parents are associated with better health, but ties to coresident children are associated with poorer health in certain contexts. Familistic culture and public pension spending have a weak but statistically significant moderating effect on the relationship between intergenerational family ties and health.This article underscores the complexity of family and highlights the need for continued theorization and measurement at the nation level to promote older adults’ health in diverse contexts.

We propose the concept of a teaching community network (TCN), an informal social network that facilitates the exchange of teaching-specific resources. We explore the role of TCNs through a case study of a sociology doctoral program at a large state university. Results reveal that students rely heavily on informal ties within the graduate student community and existing formal programs to share teaching-related resources (e.g., information and social support) and develop their identities as instructors. We suggest that graduate programs facilitate TCNs through formal teacher-training programs and structural conditions that encourage informal, one-on-one interactions (e.g., shared offices). By cultivating TCNs, graduate programs can assist students in developing their teaching skills and identities as instructors, thus training students to balance the demands of research and teaching within an academic culture.

description: Abstract: Pregnancy is a transformative journey marked by profound physiological, hormonal, and psychological changes that support fetal development. While these changes are crucial for sustaining pregnancy, they often lead to various discomforts that impact a woman’s physical health, emotional well-being, and daily functioning. Common pregnancy-related discomforts include nausea, vomiting, fatigue, heartburn, back pain, leg cramps, edema, frequent urination, and sleep disturbances. Although these discomforts are generally temporary, they can cause significant distress if not properly managed. Nurses play a pivotal role in identifying, educating, and managing these discomforts through evidence-based practices, non-pharmacological interventions, and patient-centered care. Nursing interventions focus on symptom relief, lifestyle modifications, dietary adjustments, and emotional support to ensure maternal well-being. This article provides a comprehensive review of common pregnancy discomforts, their causes, and effective nursing interventions aimed at enhancing maternal comfort and quality of life.

Olivine in the Polaris Alaskan-type Intrusion of North-central British Columbia : Implications for the Magmatic Evolution of Primitive Arc Magmas and for Convergent Margin Ni-Cu-PGE Ore-forming Systems

description: The Jurassic Polaris Alaskan-type ultramafic-mafic intrusion is a 14 km by 3 km sill-like intrusion hosted by sedimentary and volcanic rocks of the Lay Range Assemblage in the Quesnel terrane of north-central British Columbia. Olivine, the dominant mineral in the intrusion, displays a wide range of textures and compositions that reflect different environments of crystallization. Olivine compositions (n = 326) determined by electronprobe microanalysis (EPMA) span a range of forsterite contents (Fo94-79), with the most Mg-rich olivine present in chromitite, due to subsolidus exchange with chromite, and most Mg-poor olivine present in olivine clinopyroxenite. Nickel concentrations in olivine vary significantly from 3108 ppm Ni at Fo89 to 275 ppm Ni at Fo81. The lack of systematic Fo-Ni-Mn zonation from core-to-rim in Polaris olivine is indicative of pervasive diffusion and re-equilibration at high temperatures. The Mg-rich compositions of olivine in dunite, olivine wehrlite, and werhlite (Fo87.5-92) are evidence for the involvement of primitive, mantle wedge-derived parent magmas that experienced little fractionation prior to emplacement in the crust. The Fo-Ni relationships of olivine are consistent with a fractional crystallization control from dunite-olivine werhlite-wehrlite (Fo87.5-92, 1605- 3108 ppm Ni) through magnetite-rich olivine clinopyroxenite (Fo79-84, 275-550 ppm Ni), whereas Ni-rich olivine in magnetite-poor olivine clinopyroxene (Fo81.5-84, 1305-2090 ppm Ni) is accounted for by mixing between fractionated and primitive magmas. Outcrop-scale field relationships (i.e., chaotic mixing, ultramafic dikes, chromitite schlieren) in the Polaris intrusion support the operation of periodic recharge and mixing processes. Polaris olivine is distinguished by extremely low Ca concentrations (<1000 ppm, and mostly <500 ppm) compared to olivine from volcanic rocks globally, including those from subduction zone environments. Low-Ca olivine is also typical of ultramafic-mafic plutonic rocks in general (e.g., Skaergaard, Kiglapait, Bushveld, Duke Island) and may be related to pervasive diffusional loss of Ca from olivine to interstitial melt. The shallow emplacement depth of the Polaris intrusion (~12 km) requires that ascent of primitive, unfractionated magmas was relatively rapid from the mantle wedge source to maintain the observed Mg-rich olivine compositions. The Polaris intrusion shares common petrogenetic characteristics with mafic-ultramafic ore-forming conduit systems in other settings, highlighting the similarities between extensional and convergent margin Ni-Cu-PGE ore-forming systems.

description: The HBM4EU matrix-specific questionnaires have been designed to collect a select amount of information concerning individual characteristics of the participants and on different sources and routes of exposure to the 2nd round priority substances selected for study, with the aim to characterise as well as possible the level of exposure to these substances (where considered relevant) directly prior (past 24 or 48 hours) to the sampling.
 As urine and blood are currently the most likely matrices to be analysed, questionnaires have been prepared accordingly. It might be necessary to adapt some wording and use specific questions in the urine questionnaire depending on the type of urine envisioned to be sampled (e.g. morning urine, spot urine, etc.).

description: Highly valuable attributes such as high efficiency and competitive capital costs are the underlying factors for the prominence of carbon dioxide (CO2) cycles not only in theoretical fields but also in commercial applications. As a result, we are witnessing an increasing number of research projects and support for activities related to these cycles. Recently, there has been a new initiative to develop an even more promising working fluid by mixing CO2 with certain dopants. One of them seems to be the CO2-SO2 mixture. Given the promising potential of this specific mixture, which seems to be exceptionally well-suited for application in transcritical cycles [1], this paper provides an overview of the early results of the transient analysis of transcritical Rankine cycle using this mixture in waste heat recovery applications (WHR). The primary focus of this paper is to utilize the CO2-SO2 mixture in a 70-30 ratio for the double recuperated recompression Rankine cycle. In doing so, this study not only examines the unique characteristics of this mixture but also explores its potential applications for WHR under fluctuating operational conditions. The paper describes the modeling methodology implemented in Aspen Plus software and illustrates the key plant components transient operating conditions. By conducting the analysis of this working fluid, the paper aims to evaluate its effectiveness in harnessing waste heat, thereby contributing to the advancement of more sustainable and efficient energy solutions.
