SO3 removal rate and emission test of the limestone-gypsum wet desulfurization system for coal-fired power plants
Authors: Han Yuan , Zhu Yujie 
Published: September 2023

Abstract
This paper studies the SO3 removal ability of dual tower wet desulfurization (in series) and adopts a combination of on-site flue gas sampling and laboratory condensation control. A dual tower (series) supported boiler is used. The SO3 content in the original and clean flue gas of the dual cycle wet desulfurization device was measured, and the removal rate of SO3 of the device was measured. Desulfurization is calculated on the basis of the influence of unit electrical load, coal sulfur content, and desulfurization (raw material flue gas) inlet particle concentration on removal rate. This paper discusses and analyzes the SO3 and SO3 emission concentrations for SO3 removal rules in desulfurization systems. The results indicate that the total sulfur content of coal is relatively high, and the concentration of SO3 is relatively high. The traditional flue gas and net flue gas content in the dual tower wet desulfurization system (series) is relatively high. When burning sulfur-containing coal, there may be “blue smoke” in the flue gas. When the unit load changes between 182 MW and 350 MW, the SO3 removal rate of dual tower wet desulfurization (in series) is between 46.7% and 65.3%, with a net flue gas SO3 concentration of 16.0 mg/m3∼20.5 mg/m3. Due to equipment layout and other reasons, the SO3 removal rate of the primary tower is lower than that of the secondary tower. The removal rate of SO3 is also affected by the concentration of original smoke particles. Due to the condensation of SO3 on the particles and the dust removal of the adsorption tower, the higher the concentration of raw flue gas particles is, the higher the removal rate is. SO3 will be higher. The study also suggests the SO3 removal ability of double tower (series) and double ring wet desulfurization, which is better adapted to changes in load and coal. The next step is to explore the SO3 removal capacity of the dual tower system by optimizing its operating parameters. In addition, due to the arrangement of a desulfurization system after dust removal, it is impossible to control the SO3 source. Subsequent research can control the production of existing SO3 through coal distribution and combustion control.

Abstract
With the increase in the permeability of renewable energy, the randomness and uncertainty of photovoltaic power generation and wind power generation have an impact on the stable operation of the power grid. Energy storage technology can effectively improve the controllability of new energy, but the optimal allocation of energy storage capacity has always been a difficult problem limiting the development of energy storage technology. In this paper, the capacity optimization model of the complementary energy storage system is established based on the analysis of the wind-solar energy storage principle and the energy balance criterion. Then, with the minimum investment cost, the highest economic benefit, low wind and light abandonment rate and low load power shortage rate as the optimization objectives, the harmony search algorithm was used to solve the optimization model under the constraint of stable operation of the system, and the optimal capacity allocation scheme was obtained. The results of the example show that the optimization strategy in this paper can reduce the investment cost of the system and improve the reliability of the power supply and energy efficiency of the system.

Published: September 2023

Abstract
With the rising installed capacity of rooftop PV, there is an urgent need to improve the accuracy of the behind-the-meter solar generation decomposition to realize the local consumption of distributed PV in order to alleviate the grid stability problem caused by the large-scale rooftop PV access. This paper proposes a bidirectional Gated Recurrent Unit neural network based on the Attention mechanism for a behind-the-meter solar generation decomposition model. First, the temporal characteristics of customer net load data are extracted using bidirectional gated recurrent units. Then, the Attention mechanism is introduced to improve the attention to key net load information. Finally, a nonlinear mapping relationship is constructed from net load data to behind-the-meter solar generation. 184 household PV customers in the SGSC dataset are used for the example analysis. The simulation results show that the proposed method does not rely on accurate physical modeling as well as accurate numerical weather forecast data, and has good generalization in scenarios of different climate zones and good adaptability in scenarios of different seasons.

Published: September 2023

Abstract
With the construction of new power systems, the load shows significant differences between peak and valley, and the traditional system planning and scheduling operation mode faces problems such as insufficient flexibility. The power system mainly focuses on transmission lines and transformers to improve the grid’s transmission capacity. Based on the existing grid structure and substation layout, the thermal stability value algorithm is used to evaluate the load capacity of substation equipment, fully tap its operation potential, and improve the equipment’s total utilization rate, which is of great significance to ensure the reliability of the power supply. Based on the principle of heat transfer, this paper establishes the temperature model of electrical equipment contact. Finally, the experimental results demonstrate that the particle filter method proposed in this paper can effectively predict the model temperature.

Abstract
Rete ridges consist of undulations between the epidermis and dermis that enhance the mechanical properties and biological function of human skin. However, most human skin models are fabricated with a flat interface between the epidermal and dermal layers. Here, we report a micro-stamping method for producing human skin models patterned with rete ridges of controlled geometry. To mitigate keratinocyte-induced matrix degradation, telocollagen–fibrin matrices with and without crosslinks enable these micropatterned features to persist during longitudinal culture. Our human skin model exhibits an epidermis that includes the following markers: cytokeratin 14, p63, and Ki67 in the basal layer, cytokeratin 10 in the suprabasal layer, and laminin and collagen IV in the basement membrane. We demonstrated that two keratinocyte cell lines, one from a neonatal donor and another from an adult diabetic donor, are compatible with this model. We tested this model using an irritation test and showed that the epidermis prevents rapid penetration of sodium dodecyl sulfate. Gene expression analysis revealed differences in keratinocytes obtained from the two donors as well as between 2D (control) and 3D culture conditions. Our human skin model may find potential application for drug and cosmetic testing, disease and wound healing modeling, and aging studies.

Published: September 2023

Abstract
Two-photon polymerization (TPP) is a cutting-edge micro/nanoscale three-dimensional (3D) printing technology based on the principle of two-photon absorption. TPP surpasses the diffraction limit in achieving feature sizes and excels in fabricating intricate 3D micro/nanostructures with exceptional resolution. The concept of 4D entails the fabrication of structures utilizing smart materials capable of undergoing shape, property, or functional changes in response to external stimuli over time. The integration of TPP and 4D printing introduces the possibility of producing responsive structures with micro/nanoscale accuracy, thereby enhancing the capabilities and potential applications of both technologies. This paper comprehensively reviews TPP-based 4D printing technology and its diverse applications. First, the working principles of TPP and its recent advancements are introduced. Second, the optional 4D printing materials suitable for fabrication with TPP are discussed. Finally, this review paper highlights several noteworthy applications of TPP-based 4D printing, including domains such as biomedical microrobots, bioinspired microactuators, autonomous mobile microrobots, transformable devices and robots, as well as anti-counterfeiting microdevices. In conclusion, this paper provides valuable insights into the current status and future prospects of TPP-based 4D printing technology, thereby serving as a guide for researchers and practitioners.

Abstract

Aims
Heart failure with preserved ejection fraction (HFpEF) is a syndrome characterized by multiple cardiac reserve limitations during exercise. Cardiac power output (CPO) is an index of global cardiac performance and can be estimated non-invasively by echocardiography. We hypothesized that CPO reserve during exercise would be associated with impaired cardiovascular reserve, exercise intolerance, and adverse outcomes in HFpEF.

Methods and results
Exercise stress echocardiography was performed in 425 dyspnoeic patients [217 HFpEF and 208 non-heart failure (HF) controls] to estimate CPO at rest and during exercise. We classified patients with HFpEF based on the median value of changes in CPO from rest to peak exercise (ΔCPO &gt;0.49 W/100 g). Patients with HFpEF and a lower CPO reserve had poorer biventricular systolic function, impaired chronotropic response during exercise, and worse aerobic capacity than controls and those with a higher CPO reserve. During a median follow-up of 358 days, a composite outcome of all-cause mortality or HF events occurred in 30 patients. Patients with a lower CPO reserve had four-fold and nearly 10-fold increased risks of the outcomes compared with those with a higher CPO reserve and controls, respectively [hazard ratio (HR) 4.05, 95% confidence interval (CI) 1.16–10.1, P = 0.003 and HR 9.61, 95% CI 3.58–25.8, P &lt; 0.0001]. We further found that a lower CPO reserve had an incremental prognostic value over the H2FPEF score and exercise duration. In contrast, resting CPO did not predict clinical outcomes in patients with HFpEF.

Conclusion
A lower CPO reserve was associated with biventricular systolic dysfunction, chronotropic incompetence, exercise intolerance, and adverse outcomes in patients with HFpEF.
Epistemological Jangle and Jingle Fallacies in the Consumer–Brand Relationship Subfield: A Call to Action
Authors: Albert Noel , Thomson Matthew 
Published: September 2023

Abstract
For more than 20 years, the consumer–brand relationship (CBR) subfield has flourished with scores of constructs being employed. We provide an epistemological examination of its 14 most commonly measured relational constructs (e.g., Brand Love, Self-Brand Connection) collected from 767 research articles, reflecting 1,753 scales and approximately 9,200 items. We demonstrate that constructs overlap an average of 43% across all journals and 21% in top journals due to assessing highly similar or synonymous ideas (i.e., jangle). We use a combination of text and cluster analyses to show that measures of allegedly the same construct are polysemic, having an average of 5.3 different meanings (i.e., jingle). The results document in the CBR subfield the types of measurement inconsistencies and ambiguities that have sown confusion and frustration in other academic fields. We discuss the roots of these problems and offer recommendations aimed at helping scholars to improve measurement practices and to limit the presence of jingle and jangle in the CBR subfield.
Microbial dietary protein metabolism regulates GLP‐1 mediated intestinal transit

Published: September 2023

AbstractDepletion of gut microbiota is associated with inefficient energy extraction and reduced production of short‐chain fatty acids from dietary fibers, which regulates colonic proglucagon (Gcg) expression and small intestinal transit in mice. However, the mechanism by which the gut microbiota influences dietary protein metabolism and its corresponding effect on the host physiology is poorly understood. Enteropeptidase inhibitors block host protein digestion and reduce body weight gain in diet‐induced obese rats and mice, and therefore they constitute a new class of drugs for targeting metabolic diseases. Enteroendocrine cells (EECs) are dispersed throughout the gut and possess the ability to sense dietary proteins and protein‐derived metabolites. Despite this, it remains unclear if enteropeptidase inhibition affects EECs function. In this study, we fed conventional and antibiotic treated mice a western style diet (WSD) supplemented with an enteropeptidase inhibitor (WSD‐ETPi), analyzed the expression of gut hormones along the length of the intestine, and measured small intestinal transit under different conditions. The ETPi‐supplemented diet promoted higher Gcg expression in the colon and increased circulating Glucagon like peptide‐1 (GLP‐1) levels, but only in the microbiota‐depleted mice. The increase in GLP‐1 levels resulted in slower small intestinal transit, which was subsequently reversed by administration of GLP‐1 receptor antagonist. Interestingly, small intestinal transit was normalized when an amino acid‐derived microbial metabolite, p‐cresol, was supplemented along with WSD‐ETPi diet, primarily attributed to the reduction of colonic Gcg expression. Collectively, our data suggest that microbial dietary protein metabolism plays an important role in host physiology by regulating GLP‐1‐mediated intestinal transit.
Activism Is an Essential Nursing Role
Authors: Chinn Peggy L. , Kennedy Maureen Shawn 
Published: September 2023

ABSTRACT:
Nursing has a long history of activism, yet nurses are often heard to express their dislike of “politics” and their desire to stay away from the tense and contentious situations associated with political activism. Nurses, however, have a fundamental duty to advocate on behalf of their patients and communities. In this article, the authors discuss the rationale for and roots of political activism in nursing, the values that shape it, and the importance of nursing's stance on policies related to the health and well-being of those they serve. The authors also present exemplars of political activism and approaches nurses can use to address the pressing health care challenges of our time.

Abstract

Purpose
Competency-based medical education (CBME) represents a shift to a paradigm with shared definitions, explicit outcomes, and assessments of competence. The groundwork has been laid to ensure all learners achieve the desired outcomes along the medical education continuum using the principles of CBME. However, this continuum spans the major transition from undergraduate medical education (UME) to graduate medical education (GME) that is also evolving. This study explores the experiences of medical educators working to use CBME assessments in the context of the UME–GME transition and their perspectives on the existing challenges.

Method
This study used a constructivist-oriented qualitative methodology. In-depth, semistructured interviews of UME and GME leaders in CBME were performed between February 2019 and January 2020 via Zoom. When possible, each interviewee was interviewed by 2 team members, one with UME and one with GME experience, which allowed follow-up questions to be pursued that reflected the perspectives of both UME and GME educators more fully. A multistep iterative process of thematic analysis was used to analyze the transcripts and identify patterns across interviews.

Results
The 9 interviewees represented a broad swath of UME and GME leadership positions, though most had an internal medicine training background. Analysis identified 4 overarching themes: mistrust (a trust chasm exists between UME and GME); misaligned goals (the residency selection process is antithetical to CBME); inadequate communication (communication regarding competence is infrequent, often unidirectional, and lacks a shared language); and inflexible timeframes (current training timeframes do not account for individual learners' competency trajectories).

Conclusions
Despite the mutual desire and commitment to move to CBME across the continuum, mistrust, misaligned goals, inadequate communication, and inflexible timeframes confound such efforts of individual schools and programs. If current efforts to improve the UME–GME transition address the themes identified, educators may be more successful implementing CBME along the continuum.

Authors: Najor Anna , Melson Valerie , Lyu Junrui , Fadadu Priyal , Bakkum-Gamez Jamie , Sherman Mark , Kaunitz Andrew , Connor Avonne , Destephano Christopher 
Published: September 2023

OBJECTIVE:
We use the person-centered Pathway to Treatment framework to assess the scope of evidence on disparities in endometrial cancer stage at diagnosis. This report is intended to facilitate interventions, research, and advocacy that reduce disparities.

DATA SOURCES:
We completed a structured search of electronic databases: PubMed, EMBASE, Scopus, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials databases. Included studies were published between January 2000 and 2023 and addressed marginalized population(s) in the United States with the ability to develop endometrial cancer and addressed variable(s) outlined in the Pathway to Treatment.

METHODS OF STUDY SELECTION:
Our database search strategy was designed for sensitivity to identify studies on disparate prolongation of the Pathway to Treatment for endometrial cancer, tallying 2,171. Inclusion criteria were broad, yet only 24 studies addressed this issue. All articles were independently screened by two reviewers.

TABULATION, INTEGRATION, AND RESULTS:
Twenty-four studies were included: 10 on symptom appraisal, five on help seeking, five on diagnosis, and 10 on pretreatment intervals. Quality rankings were heterogeneous, between 3 and 9 (median 7.2) per the Newcastle–Ottawa Scale. We identified three qualitative, two participatory, and two intervention studies. Studies on help seeking predominantly investigate patient-driven delays. When disease factors were controlled for, delays of the pretreatment interval were independently associated with racism toward Black and Hispanic people, less education, lower socioeconomic status, and nonprivate insurance.

CONCLUSIONS:
Evidence gaps on disparities in timeliness of endometrial cancer care reveal emphasis of patient-driven help-seeking delays, reliance on health care–derived databases, underutilization of participatory methods, and a paucity of intervention studies.

SYSTEMATIC REVIEW REGISTRATION:
Given that PROSPERO was not accepting systematic scoping review protocols at the time this study began, this study protocol was shared a priori through Open Science Framework on January 13, 2021 (doi: 10.17605/OSF.IO/V2ZXY), and through peer review publication on April 13, 2021 (doi: https://doi.org/10.1186/s13643-021-01649-x).
The Role of En Bloc Resection in the Modern Era for Primary Spine Tumors
Authors: Yeung Caleb M. , Bilsky Mark , Boland Patrick J. , Vaynrub Max 
Published: September 2023

Study Design.
A literature review.

Objective.
The aim of this review is to provide an overview of benign and malignant primary spine tumors and a balanced analysis of the benefits and limitations of (and alternatives to) surgical treatment with en bloc resection.

Summary of Background Data.
Primary spine tumors are rare but have the potential to cause severe morbidity, either from the disease itself or as a result of treatment. The prognosis, goals, and treatment options vary significantly with the specific disease entity. Appropriate initial management is critical; inappropriate surgery before definitive treatment can lead to recurrence and may render the patient incurable, as salvage options are often inferior.

Methods.
We performed a comprehensive search of the PubMed database for articles relevant to primary spine neoplasms and en bloc spine surgery. Institutional review board approval was not needed.

Results.
Although Enneking-appropriate en bloc surgery can be highly morbid, it often provides the greatest chance for local control and/or patient survival. However, there is growing data to support modern radiotherapy as a feasible and less morbid approach to certain primary neoplasms that historically were considered radioresistant.

Conclusions.
Choosing the optimal approach to primary spine tumors is complex. A comprehensive and up-to-date assessment of the evidence is required to guide patient care and to balance the often-competing goals of prolonging life and preserving quality of life.
