Exergy Analysis of Gas Turbine Open Cycle with Pressure Gain Combustion Based on Humphrey Cycle

Abstract This paper describes an exergy comparison of the pressure gain combustion (PGC) gas turbine (GT) with conventional GT. PGC has recently emerged as a promising approach to achieve major performance improvements in the current gas turbines operating on the Joule cycle, where the potential for major performance upgrades has nearly plateaued. However, the inherently unsteady and periodic nature of this combustion technology presents challenges in modelling the PGC process and understanding its impact on the cycle. In this work, PGC is represented by a steady-state model of constant volume combustion based on the Humphrey cycle, along with a constant pressure combustion loss model for capturing practical losses. Exergy performance was analysed in terms of exergy destruction for three air-cooled GT cycles with different combustors: a conventional isobaric combustor, an optimistic PGC combustor with no losses and a realistic PGC combustor with losses. Gas turbine cycles were modelled in WTEMP (Web-based Thermo-Economic Modular Program) software, a modular and flexible cycle analysis tool developed by TPG at the University of Genova. Simulations were performed at compressor pressure ratios from 5 to 40 at turbine inlet temperatures of TIT=1300°C and TIT=1700°C, and results were analysed in terms of exergy destruction and exergy efficiency. It was found that a PGC combustor with optimistic losses recovers more exergy than a conventional combustor due to pressure gain. At a cycle pressure ratio of 20 and 1700°C TIT, the PGC combustor with a pressure ratio of 1.35 resulted in an exergy efficiency of 79.6% compared to 77.9% of the Joule combustor. However, with realistic loss from inlet pressure drop and constant pressure combustion in the PGC combustor, the PGC combustor showed higher irreversibility than conventional combustor but the overall benefit on the cycle was retained at low compressor pressure ratios. Moreover, the percentage increase in turbine irreversibility from blade cooling was found to be slightly lower for the PGC cycle as compared to Joule.

Formation of a healthy lifestyle of high school students using the «Fitness Mix» means

The article analyzes the importance of developing a healthy lifestyle among high school girls and the role of the "Fitness Mix" methodology in this process. The study explores the use of "Fitness Mix" as an innovative tool for enhancing physical activity levels, improving performance, and promoting overall health among adolescents. It emphasizes how combining different types of physical activities, such as aerobics, strength training, and stretching, can be integrated into physical education classes to achieve comprehensive results. In addition to physical exercises, the article highlights the importance of the theoretical component, which includes principles of healthy eating, regular sleep and rest routines, prevention of harmful habits, and maintaining mental health. Special attention is given to the analysis of scientific research and practical examples that confirm the effectiveness of using fitness technologies in schools. Alternatives to traditional modular physical education programs are discussed, broadening the opportunities for educating and developing adolescents. The study emphasizes the need to consider individual student characteristics when designing exercise programs, ensuring optimal results and maintaining motivation for regular physical activity. The article also provides recommendations for educators and trainers on implementing «Fitness Mix» into the school curriculum to promote the development of sustainable healthy lifestyle habits among youth. A range of examples is analyzed regarding the combination of different types of physical activity, specifically aerobics, strength exercises, stretching, etc., with an additional focus on important aspects such as healthy eating principles, sleep and rest routines, prevention of harmful habits, and mental health preservation. The importance of considering the individual characteristics of students when designing exercise programs is underscored.

Computing Precise Control Interface Specifications

Verifying network programs is challenging because of how they divide labor: the control plane computes high level routes through the network and compiles them to device configurations, while the data plane uses these configurations to realize the desired forwarding behavior. In practice, the correctness of the data plane often assumes that the configurations generated by the control plane will satisfy complex specifications. Consequently, validation tools such as program verifiers, runtime monitors, fuzzers, and test-case generators must be aware of these control interface specifications (ci-specs) to avoid raising false alarms. In this paper, we propose the first algorithm for computing precise ci-specs for network data planes. Our specifications are designed to be efficiently monitorable —concretely, checking that a fixed configuration satisfies a ci-spec can be done in polynomial time. Our algorithm, based on modular program instrumentation, quantifier elimination, and a path-based analysis, is more expressive than prior work, and is applicable to practical network programs. We describe an implementation and show that ci-specs computed by our tool are useful for finding real bugs in real-world data plane programs.

Modular Multitree Genetic Programming for Evolutionary Feature Construction for Regression

Genomic selection strategies for the German Merino sheep breeding programme - A simulation study.

Genomic selection is widely implemented in livestock breeding programmes across species. Its potential is also evident for sheep breeding; however, it has several limitations, particularly because of the high genetic diversity across and within sheep breeds. In Germany, the predominant sheep breed is the Merino sheep. Until now, there has been no use of genomic selection in the German Merino sheep breeding programme. In this simulation study, different genomic selection strategies were compared with a reference scenario with a breeding value estimation based on pedigree BLUP. A simplified version of the German Merino sheep breeding programme, including a health and a production trait in the breeding goal, was simulated via the R package Modular Breeding Program Simulator (MoBPS). Real genotype data were used to create a population specific simulation. The reference scenario was compared with several alternative scenarios in which selection was based on single-step GBLUP (ssGBLUP) breeding value estimation with varying genotyping strategies. In addition to scenarios in which all male and all male plus all female lambs were genotyped, scenarios with a preselection of lambs, that is only a certain proportion (top 25%, top 50%) genotyped, were simulated. The results revealed that genetic gain increased with increasing numbers of available genotypes. However, marginal gains decreased with increasing numbers of genotypes. Compared with the reference scenario, genotyping the top 25% of male lambs increased the genetic gain for the breeding ram population by 13% for both traits whereas genotyping the top 50% of male lambs or all male lambs led to increases of 18% (17%) or 26% (21%) for the health (production) trait, respectively. The potential of genotyping females in addition to male lambs was less evident on the male side with no significant differences between the scenarios with different proportions of genotyped females. The results have shown that genomic selection can be a valuable tool to increase genetic gain in the German Merino sheep population and that the genotyping of a certain proportion of animals might lead to substantial improvement over pedigree-based breeding value estimation. Nevertheless, further studies, especially economic evaluations, are needed before practical implementation.

Integrating Data Analytics Training into Curricula at Small Colleges: A Practical Framework for Enhancing Student Skills

Quantitative Data Analytics (QDA) is a critical skill for professionals across various natural science disciplines. However, college curricula, especially at small colleges, often lag behind the evolving workforce’s needs due to limited faculty resources. Despite abundant training materials, there is a noticeable gap in practical frameworks for effectively developing and implementing QDA training programs, particularly addressing existing curriculum gaps and resource constraints. This study presents a practical framework for developing introductory QDA training programs tailored for non-statistical majors at resource-constrained small colleges with various educational settings. Employing a design science strategy, we developed a modular co-curricular QDA Training Program (CQDATP), consisting of five training modules refined over three iterative phases. This flexible design integrates seamlessly with existing courses or can function as standalone workshops, bolstering students’ preparedness for advanced courses and research opportunities. Our program evaluation indicates that our approach significantly enhanced students’ QDA capabilities without necessitating extensive curriculum overhauls. By focusing on adaptability and resource efficiency, our framework holds the potential to benefit educators, curriculum developers, and administrators at small colleges, ensuring that graduates are well-prepared for data-driven industries, even when resources are limited.

A Comprehensive Thermodynamic Analysis of Gas Turbine Combined Cycles With Pressure Gain Combustion Based on Humphrey Cycle

Abstract The paper describes a comprehensive thermodynamic analysis of the gas turbine combined cycle (CC) equipped with pressure gain combustion (PGC) based on the Humphrey cycle. PGC is represented by a steady-state zero-dimensional constant volume combustion (CVC) model with practical loss models for a realistic interpretation. Simulations were performed in WTEMP (Web-based Thermo-Economic Modular Program) software, a modular cycle analysis tool developed at the University of Genova. Results were analyzed at the optimistic and realistic PGC loss scenarios. For the PGC open cycle, with optimistic combustor losses, efficiency was higher than Joule at all operating conditions. However, with realistic combustor losses, a higher TIT was found to alleviate some of the losses in the combustor and at a pressure ratio of 25, a 1700°C TIT cycle showed a benefit of 1.7 p.p., while 1300°C TIT showed no advantage. Moreover, with the reduction in first turbine stage efficiency from pulsating outflow, only the high TIT cycle showed benefit at pressure ratios less than 15. Looking into combined cycles with realistic combustor losses, PGC was found to be advantageous in terms of specific work but not efficiency at actual operating conditions. However, with a further reduction of combustor-related losses, the PGC CC could outperform the Joule equivalent in terms of efficiency. The sensitivity analysis with losses showed that the mitigation of constant pressure combustion loss is more important than the inlet pressure loss for PGC in CC application.

The Impact of a Modular Robotic Total Mesorectal Excision Training Program on Perioperative and Oncological Outcomes in Robotic Rectal Cancer Surgery.

Structured training programs for robotic colorectal surgery are limited, and there are concerns about surgical outcomes and operating times. To compare perioperative and oncological outcomes of robotic total mesorectal excision for rectal cancer performed by expert consultants and surgical trainees in a modular surgical training program. Retrospective cohort study. Conducted at a colorectal training referral center for robotic surgery. Consecutive robotic total mesorectal excision cases between May 2013 and December 2017 were evaluated retrospectively from a prospectively maintained institutional database and divided into 2 groups: group I comprised expert surgeons and group II comprised supervised trainees. Robotic total mesorectal excision training modules (5 modules) were performed stepwise with increasing complexity. Patients' demographic, perioperative, and oncological data were collected. Modular robotic training. Comparable R0 resection rate, lymph node harvest, and oncological outcomes between experts and trainees, suggesting good quality in oncological resection. A total of 177 robotic total mesorectal excision resections were performed (group I: n = 80, group II: n = 97). Four trainees completed 37.5 modules each. Patients' age, sex, and BMI were similar between groups. Group II had a higher ASA III score (6.3% vs 25.8%, p = 0.002). Clinical TNM and neoadjuvant chemoradiotherapy rates were similar. Group II had a longer operative time (225 [197.5-297.5] vs 250 [230-300] minutes, p = 0.004). No conversion occurred. There were no differences in intra- or postoperative outcomes between groups. The rate of R0 resection and the number of harvested lymph nodes were also similar between groups. The median follow-up was 75 (64.0-81.7) and 47 (38.0-55.0) months, respectively. Local and distant recurrence rates, 5-year overall survival (81.1% group I vs 81.3% group II, p = 0.832), and 5-year disease-free survival (79.7% group I vs 80.7% group II, p = 0.725) were similar between groups. The groups operated in 2 consecutive periods. The robotic total mesorectal excision modular surgical training program maximizes training experience without significantly affecting the perioperative and oncological outcomes of patients with rectal cancer.

Full mission evaluation of EnMAP water leaving reflectance products using three atmospheric correction processors.

This study presents what we believe is the first extensive assessment of the water reflectance products from the German hyperspectral Environmental Mapping and Analysis Program (EnMAP). We evaluate EnMAP's standard normalized water leaving reflectance [ρW]N over 17 water sites in the first two years of the mission. The EnMAP [ρW]N standard product is generated by a dedicated water atmospheric correction (AC) called the Modular Inversion Program (MIP). The quality of the [ρW]N retrievals was assessed using in situ hyperspectral measurements and Aerosol Robotic Network - Ocean Colour (AERONET-OC) multispectral measurements. The results showed very good agreement between in situ hyperspectral match-ups and EnMAP [ρW]N, with an underestimation of EnMAP of -17.37% (bias, β) and an error (ϵ) of 23.75% at 418 - 797 nm. Two other AC processors were also investigated: the polynomial based algorithm applied to MERIS (Polymer) and the atmospheric correction for OLI lite (Acolite). The intercomparison exercise between the three AC methods applied to EnMAP data using the hyperspectral match-up dataset showed better statistical metrics for MIP (ϵ=23%,β=-17.37%) compared to Polymer (ϵ=42.20%,β=-2.43%) and Acolite (ϵ=97%,β=97%). The superior performance of MIP was further confirmed by the validation results obtained with the multispectral match-up dataset; MIP retrievals show good agreement with in situ measurements at the majority of study sites. Conversely, Polymer and Acolite retrievals tended to overestimate, especially in clearer waters as the Lampedusa study site.

The factors influencing the demand for the Russian language, increasing motivation to study it and the demand for Russian education in general among the youth of Tanzania, as well as the formation of a positive image of Russia in the minds of Tanzanians, are identified. The conditions, «deficits» and potential «growth points» of the promotion of the Russian language in the education system of Tanzania are determined. The article presents the results of the survey conducted during the official visit of the delegation of the Samara State University of Social Sciences and Education to Tanzania, which determined the future prospects of the study, which will result in designing a modular training program for teachers of Russian as a foreign language for educational organizations of the United Republic of Tanzania in the system of Russian teacher training education, including a Russian as a foreign language course at a preparatory department, bachelor’s and master’s degree programs and advanced training for teachers of Russian as a foreign language.

Public Health Surveillance in Electronic Health Records: Lessons From PCORnet.

PCORnet, the National Patient-Centered Clinical Research Network, is a large research network of health systems that map clinical data to a standardized data model. In 2018, we expanded existing infrastructure to facilitate use for public health surveillance. We describe benefits and challenges of using PCORnet for surveillance and describe case studies. In 2018, infrastructure enhancements included addition of a table to store patients' residential zip codes and expansion of a modular program to generate population health statistics across conditions. Chronic disease surveillance case studies conducted in 2019 assessed atrial fibrillation (AF) and cirrhosis. In April 2020, PCORnet established an infrastructure to support COVID-19 surveillance with institutions frequently updating their electronic health record data. By August 2023, 53 PCORnet sites (84%) had a 5-digit zip code available on at least 95% of their patient populations. Among 148,223 newly diagnosed AF patients eligible for oral anticoagulant (OAC) therapy, 43.3% were on any OAC (17.8% warfarin, 28.5% any novel oral anticoagulant) within a year of the AF diagnosis. Among 60,268 patients with cirrhosis (2015-2019), common documented etiologies included unknown (48%), hepatitis C infection (23%), and alcohol use (22%). During October 2022 through December 2023, across 34 institutions, the proportion of COVID-19 patients who were cared for in the inpatient setting was 9.1% among 887,051 adults aged 20 years or older and 6.0% among 139,148 children younger than 20 years. PCORnet provides important data that may augment traditional public health surveillance programs across diverse conditions. PCORnet affords longitudinal population health assessments among large catchments of the population with clinical, treatment, and geographic information, with capabilities to deliver rapid information needed during public health emergencies.

Satisfaction with a new patient education program for children, adolescents, and young adults with differences of sex development (DSD) and their parents.

ObjectiveEvaluation of the participant satisfaction with a newly developed interdisciplinary, modular education program for children, adolescents, and young adults with differences of sex development (DSD) and their parents. MethodsThe two-day program including tailored medical information, peer consultation and psychological support aimed to improve diagnosis-specific knowledge and empowerment. Post-training satisfaction was measured using an adapted ZUF-8 questionnaire, scoring from 5 (worst) to a maximum of 26 (best) for persons aged 6–17 and from 10 to 40 points for adults, including 2 open-ended questions. ResultsThe questionnaire, completed by 89 children (6–13 years), 92 adolescents (14–17 years), 47 young adults (18–24 years), and 345 parents, revealed consistent high satisfaction with the program regardless of age or diagnosis (children 24.4 ± 2.1, adolescents 23.5 ± 2.7; young adults 36.0 ± 4.0, parents 36.6 ± 3.4). Neither sociodemographic factors nor diagnosis burden, shame, or informedness showed relevant associations with satisfaction levels. Participants highlighted exchange and open atmosphere as key satisfaction elements. ConclusionSatisfaction with the new education program was high in all examined groups. Implementing it in routine care requires further analysis to determine the program's long-term effects on well-being and knowledge. InnovationThe first educational program for young people with DSD addressing their specific challenges through inclusive language, an open approach to sex and gender and the inclusion of self-help groups.

Systematic review and narrative synthesis of the experiences of individuals with chronic pain participating in digital pain management interventions.

The use of digital pain management interventions has grown since the Covid 19 pandemic. The aim of this study was to systematically review and synthesise evidence from qualitative studies regarding the experiences of individuals with chronic pain participating in digital pain management interventions in primary care and community settings. Fourteen databases were searched, as well as citation tracking and hand-searching reference lists of included articles. The latest search was completed by 07/07/2023. Qualitative studies of patient and carer perspectives of digital pain management interventions for adults aged 18 and over with non-malignant chronic pain were included. All studies were appraised for quality using the Critical Appraisal Skills Programme Qualitative Checklist. A narrative synthesis approach was used to synthesise the findings. Normalisation Process Theory was used to understand how individuals with chronic pain make sense of digital pain management interventions and incorporate knowledge, skills and strategies learnt into their day-to-day lives. Eleven studies, encompassing both digital applications for use on smartphones/ mobile devices and user-directed online modular programmes, were included in the synthesis. Three main themes and related subthemes were identified from the included studies: 1) Making sense of the digital intervention (Subthemes: Tailoring to user's needs; Human contact and support; Accessibility of the digital intervention; Personal and environmental factors affecting engagement with digital interventions); 2) Initiating and Maintaining Behaviour Change (Subthemes: Planning activity; Being active); and 3) Personal Growth (Subthemes: Gaining understanding and skills; Gaining and acting on feedback; Negotiating a new relationship with pain). Recommendations. The key recommendations from our findings are that digital pain management interventions should provide: Specific and tailored information for individual participants.Focus on changing attitudes and behaviours and reframing perceptions of pain.Structured goal setting with prompts to review goals.Potential healthcare professional support alongside the digital intervention.Limitations of the review. To reduce bias, it would have been preferable for more than one author to independently fully analyse each paper and to identify themes and sub-themes. Instead, the identified themes and sub-themes were discussed with two other authors in the team (ES, LW) to reach a consensus view on final themes and sub-themes. One author (JS) received a Research Internship and Research Initiation Award funded by NIHR Applied Research Collaboration (ARC) Wessex (https://www.arc-wx.nihr.ac.uk/) and NHS England (https://www.england.nhs.uk/). The protocol for this review was registered with the National Institute of Health Research (NIHR) PROSPERO international database for registering systematic reviews (PROSPERO Registration Number CRD42021257768).

Organ Evolution: Emergence of Multicellular Function.

Instances of multicellularity across the tree of life have fostered the evolution of complex organs composed of distinct cell types that cooperate, producing emergent biological functions. How organs originate is a fundamental evolutionary problem that has eluded deep mechanistic and conceptual understanding. Here I propose a cell- to organ-level transitions framework, whereby cooperative division of labor originates and becomes entrenched between cell types through a process of functional niche creation, cell type subfunctionalization, and irreversible ratcheting of cell interdependencies. Comprehending this transition hinges on explaining how these processes unfold molecularly in evolving populations. Recent single-cell transcriptomic studies and analyses of terminal fate specification indicate that cellular functions are conferred by modular gene expression programs. These discrete components of functional variation may be deployed or combined within cells to introduce new properties into multicellular niches, or partitioned across cells to establish division of labor. Tracing gene expression program evolution at the level of single cells in populations may reveal transitions toward organ complexity.

Analysis of AP1000 Small-Break Loss-of-Coolant Accident Using Reactor Transient Simulator

The Westinghouse Electric Company’s Advanced Passive Reactor (AP1000) is characterized by the incorporation of passive safety systems (PSSs) designed to ensure core cooling during transient events. The assessment of PSSs requires evaluation of their performance through a combination of experiments and simulations employing various thermal-hydraulic codes. In addition, detailed evaluation of PSSs for a specific reactor system transient analysis such as loss-of-coolant-accident analysis supports understanding representative integral effects test facility development and the further evolution model development and assessment process. Developing a reactor system code is a complex and time-consuming process that requires significant engineering expertise and effort. It can take several months to even years to complete in the early stages of reactor system design and analysis. However, this process can be expedited through the use of transient simulator models for similar reactor systems, which can be used for lesson learning and training purposes. This study uses the Personal Computer Transient Analyzer (PCTRAN) code. The main advantage of PCTRAN is its ease of use and ability to run faster than real time. This study presents the results obtained for a small-break loss-of-coolant accident (SBLOCA) for two breaks using the full version (licensed) of PCTRAN. The purpose of this investigation is to evaluate the overall system behavior during the postulated SBLOCA event as well as assess the capability of the PCTRAN code to reproduce the system response during transient events. The obtained results were compared with the Westinghouse NOTRUMP system code. The PCTRAN code proved to be reliable in predicting the qualitative behavior of the system in both transient cases. As for the system response, it was found that it is contingent on the activation time of the PSSs. The differences in reactor coolant system pressure between the two codes were attributed to the critical flow model and simplification of mass and energy balance. Despite PCTRAN’s limitations, it can still provide a reasonable prediction of various reactor parameters such as pressure, mass flow rate, and void fraction during a SBLOCA scenario. It is worth noting that PCTRAN currently employs a bulk approach similar to that of the Modular Accident Analysis Program (MAAP) and MELCOR codes. However, the upcoming version of PCTRAN will include an artificial intelligence–based detection and accident prevention system, as well as different models for different reactor components. Consequently, PCTRAN has the potential to be upgraded to match the system thermal-hydraulic codes of the U.S. Nuclear Regulatory Commission and become more widely used in cybersecurity to safeguard nuclear power plants from cyberattacks.
