Design and Performance of Low Heating Value Fuel Gas Turbine Combustors

General Electric Company is developing and testing low heating value fuel gas turbine combustors for use in integrated gasification combined cycle power generation systems. This paper presents the results of a series of combustion tests conducted at the pilot scale coal gasification and high temperature desulfurization system located at GE Corporate Research and Development in Schenectady, New York. Tests were performed in a modified GE MS6000 combustor liner operating at a pressure of 10 bar and over a wide load range (combustor exit temperatures from 760 to 1400°C). The primary objective of these tests was to compare and contrast the performance (emissions, flame stability, and combustor liner temperatures) of six different low heating value fuel nozzle designs, representing three distinct nozzle concepts. With 2200 to 4600 ppmv NH3 in the fuel, the conversion of fuel NH3 to NOx was roughly independent of fuel nozzle type, and ranged from about 70% at low combustor exit temperatures to about 20% at high combustor exit temperatures. For all of the fuel nozzles, CO emissions were typically less than 5 ppmv (on a dry, 15% O2 basis) at combustor exit temperatures greater than 980°C. Significant differences in CO emissions were observed at lower combustor exit temperatures. Some differences in liner temperatures and flame stability were also observed with the different nozzles. In general, nozzles which produced lower CO emissions and greater flame stability had higher fuel swirl angles and resulted in higher combustor liner temperatures. The nozzle with the best overall performance (consisting of concentric axial air and fuel swirlers and an air cooled mixing cup) has been selected for use at a commercial site.Copyright © 1996 by ASME
Effects of Varying the Fin Width, Fin Height, Gate Dielectric Material, and Gate Length on the DC and RF Performance of a 14-nm SOI FinFET Structure

The FinFET architecture has attracted growing attention over the last two decades since its invention, owing to the good control of the gate electrode over the conductive channel leading to a high immunity from short-channel effects (SCEs). In order to contribute to the advancement of this rapidly expanding technology, a 3D 14-nm SOI n-FinFET is performed and calibrated to the experimental data from IBM by using Silvaco TCAD tools. The calibrated TCAD model is then investigated to analyze the impact of changing the fin width, fin height, gate dielectric material, and gate length on the DC and RF parameters. The achieved results allow gaining a better understanding and a deeper insight into the effects of varying the physical dimensions and materials on the device performance, thereby enabling the fabrication of a device tailored to the given constraints and requirements. After analyzing the optimal values from different changes, a new device configuration is proposed, which shows a good improvement in electrical characteristics.
Artificial intelligence and atrial fibrillation

In the context of atrial fibrillation (AF), traditional clinical practices have thus fallen short in several domains, such as identifying patients at risk of incident AF or patients with concomitant undetected paroxysmal AF. Novel approaches leveraging artificial intelligence have the potential to provide new tools to deal with some of these old problems.
PENGALAMAN MAHASISWI BERHIJAB YANG MENGALAMI CATCALLING

ABSTRACT This study is a study of the experiences of hijab students who experience catcalling. Catcalling can occur regardless of place, class, age and social class. Most victims of harassment are often blamed for their wear which is considered inviting, but in fact this phenomenon also occurs in some female students who wear the hijab, resulting in a mismatch between expectations and their social environment. This study aims to see how experiences are experienced, the form of verbal and non-verbal catcalling messages, and self-concept in female hijab students after experiencing catcalling. By using Alfred Schutz's phenomenological method as a qualitative research method and using in-depth interview techniques as a data collection technique, the researchers found that the forms of verbal and non-verbal catcalling were experienced by different informants. This experience made female hijab students gain an understanding of why catcalling happened to them and resulted in a self-concept with physical and social aspects that were mostly negative rather than positive. Keywords: experience, catcalling, hijab students ABSTRAK Penelitian ini merupakan penelitian mengenai pengalaman mahasiswi berhijab yang mengalami catcalling.

When Robot (Vs. Human) Employees Say “Sorry” Following Service Failure

ABSTRACT This paper aims to understand travelers’ responses to apologies of robot (vs. human) employees following service failures and how travelers’ age influences their responses. Using a scenario-based between-subject experimental design, Study 1 finds that human employees’ apologies (vs. no apologies) enhance travelers’ revisit intention while robot employees’ apologies do not have such an effect. Study 2 reveals that human employees’ apologies increase satisfaction among younger travelers, whereas robot employees’ apologies increase satisfaction among older travelers. Managers in the hospitality and tourism industry may train their employees (vs. design robot employees’ apology messages) effectively to serve travelers in different ages.
Urinary Biomarkers in Interstitial Cystitis/Bladder Pain Syndrome and Its Impact on Therapeutic Outcome

Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as a chronic bladder disorder with suprapubic pain (pelvic pain) and pressure and/or discomfort related to bladder filling accompanied by lower urinary tract symptoms, such as urinary frequency and urgency without urinary tract infection (UTI) lasting for at least 6 weeks. IC/BPS presents significant bladder pain and frequency urgency symptoms with unknown etiology, and it is without a widely accepted standard in diagnosis. Patients’ pathological features through cystoscopy and histologic features of bladder biopsy determine the presence or absence of Hunner lesions. IC/PBS is categorized into Hunner (ulcerative) type IC/BPS (HIC/BPS) or non-Hunner (nonulcerative) type IC/BPS (NHIC/BPS). The pathophysiology of IC/BPS is composed of multiple possible factors, such as chronic inflammation, autoimmune disorders, neurogenic hyperactivity, urothelial defects, abnormal angiogenesis, oxidative stress, and exogenous urine substances, which play a crucial role in the pathophysiology of IC/BPS. Abnormal expressions of several urine and serum specimens, including growth factor, methylhistamine, glycoprotein, chemokine and cytokines, might be useful as biomarkers for IC/BPS diagnosis. Further studies to identify the key molecules in IC/BPS will help to improve the efficacy of treatment and identify biomarkers of the disease. In this review, we discuss the potential medical therapy and assessment of therapeutic outcome with urinary biomarkers for IC/BPS.
Brain Morphometry and Chronic Inflammation in Bangladeshi Children Growing up in Extreme Poverty

Over 300 million children grow up in environments of extreme poverty, and the biological and psychosocial hazards endemic to these environments often expose these children to infection, disease, and consequent inflammatory responses. Chronic inflammation in early childhood has been associated with diminished cognitive outcomes and despite this established relationship, the mechanisms explaining how inflammation affects brain development are not well known. Importantly, chronic inflammation is very common in areas of extreme poverty, raising the possibility that it may serve as a mechanism explaining the known relationship between low socioeconomic status (SES) and atypical brain development. To examine these potential pathways, seventy-nine children growing up in an extremely poor, urban area of Bangladesh underwent structural MRI scanning at six years of age. Structural brain images were submitted to Mindboggle software, a Docker-compliant and high-reproducibility tool for tissue segmentation and regional estimations of volume, surface area, cortical thickness, sulcal depth, and mean curvature. Concentration of C-reactive protein was assayed at eight time points between infancy and five years of age and the frequency with which children had elevated concentrations of inflammatory marker served as the measure of chronic inflammation. Children’s SES was measured with years of maternal education and income-to-needs. Chronic inflammation predicted total brain volume, total white matter volume, average sulcal depth, and bilateral putamen volumes. Chronic inflammation also mediated the link between maternal education and bilateral putamen volumes. These findings suggest that chronic inflammation is associated with brain morphometry globally and in the putamen, and further suggests that inflammation may be a potential mechanism linking SES to brain development.
Cytochrome b561 Serves as a Potential Prognostic Biomarker and Target for Breast Cancer

Purpose Cytochrome b561 (CYB561) is a transmembrane protein and participates in ascorbate recycling and iron homeostasis. However, its role in breast cancer remains unclear. Patients and Methods In this study, we explored the expression pattern and prognostic value of CYB561 in breast cancer through The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), PrognoScan and Kaplan–Meier Plotter and confirmed its mRNA expression in human breast cell lines. LinkedOmics, Metascape and Gene Expression Profiling Interactive Analysis (GEPIA2) databases were applied to investigate the co-expression genes and construct microRNA (miRNA) networks associated with CYB561. The correlations between CYB561 and immune infiltration cells and genes were also illustrated. Results The CYB561 expression was upregulated in breast cancer tissues and cell lines and significantly correlated with the clinical features of breast cancer patients. High CYB561 expression was associated with poor survival and was an independent risk factor for overall and disease-specific survival. Functional enrichment analysis showed that CYB561 and its co-expressed genes were mainly enriched in lipid biosynthetic process, Wnt signaling pathway, Hippo signaling pathway, etc. The miRNA network analysis suggested that hsa-miR-497 was negatively correlated with CYB561 expression and was predicted to direct target CYB561. CYB561 expression was positively correlated with infiltrating levels of CD4+ T cells, neutrophils and dendritic cells in breast cancer. Subsequent analysis found that B cells could predict the outcome of breast cancer. Also, CYB561 showed strong correlations with diverse immune marker sets in breast cancer. Conclusion CYB561 may serve as a potential prognostic biomarker and target for breast cancer. Our findings laid foundation for future research on molecular mechanisms of CYB561 in breast cancer.
Risk Factors of Unsatisfactory Robot-Assisted Pedicle Screw Placement: A Case-Control Study

Objective To identify potential risk factors of unsatisfactory screw position during robot-assisted pedicle screw fixation. Methods A retrospective analysis of robot-assisted pedicle screw fixation performed in Beijing Jishuitan Hospital from March 2018 to March 2019 was conducted. Research data was collected from the medical record and imaging systems. Univariate tests were performed on the potential risk factors (patient’s characteristics and surgical factors) of unsatisfactory screw position during robot-assisted pedicle screw fixation. For statistically significant variables in univariate tests, a logistic regression test was used to identify independent risk factors for unsatisfactory screw position. Results A total of 780 pedicle screws placed in 163 robot-assisted surgeries were analyzed. The rate of perfect screw positions was 93.08%, and the unsatisfactory rate was 6.92%. In patients with severe obesity (body mass index ≥ 30 kg/m2) (odds ratio [OR], 2.459; 95% confidence interval [CI], 1.199–5.044; p=0.014), osteoporosis (T ≤ -2.5) (OR, 1.857; 95% CI, 1.046–3.295; p=0.034), and the segments 3 levels away from the tracker (OR, 2.216; 95% CI, 1.119–4.387; p=0.022), robot-assisted pedicle screw placement has a higher risk of screw malposition. Conclusion During robot-assisted pedicle screw placement for patients with severe obesity, osteoporosis, and segments 3 levels away from the tracker, vigilance should be maintained during surgery to avoid postoperative complications due to unsatisfactory screw position.
GETTING BACK TO BACK: ALTERNATE BEHAVIORS FOR A WEB BROWSER'S BACK BUTTON

This paper concerns the ubiquitous Back button found in most Web browsers. First, we outline why Back is an effective method for revisiting WWW pages: a) It allows rapid return to very recently visited pages, which comprises the majority of pages a person wishes to return to; b) People can use it even with a naive model of the way it works; c) People usually keep it on permanent display because it is visually compact; and d) Back works via a simple ‘click until the desired page is recognized’ strategy. Second, we investigate the behavior of Back. The typical stack-based behavior underlying Back is problematic because some previously seen pages are not reachable through it. To get around this problem, we offer several alternate behaviors of the Back button, all based upon a recency model. The advantage of recency is that all previously seen pages are now available via Back. Because trade-offs exist, we present both problems and prospects of these different Back behaviors in various navigational situations.
The Match Factor: Exploring the Match Between Expectations and Experiences and Its Effect on Student Retention TCU Retention Data Analysis Committee

A photographic film cassette has a spool, rotation of which causes a film leader to advance outside of a cassette shell. In a receiving recess formed on a spool end for receiving a rewinding shaft of a camera, a pentagonal circumference is formed for receiving a driving force from the rewinding shaft. Inclined planes are formed on the inside of the receiving recess for guiding insertion of the rewinding shaft into the receiving recess. Because the spool is rotated in axial coincidence with the rewinding shaft, the film can be advanced reliably outside of the cassette by slipping the outermost turn of the wound film smoothly with reference to a self-advancing mechanism. In a preferred embodiment, a film cassette is constituted by two shell halves, with one of which a part of the film passage mouth is integrated. A positioning member is integrated with the same shell half for positioning the cassette shell in contact with a receiving member formed in a film loading chamber. The film passage mouth thus can be connected precisely to the film passageway in the camera.
Operational and Safety Effects of Right-Turn Deceleration Lanes on Urban and Suburban Arterials

Right-turn deceleration lanes reduce the potential for rear-end collisions from vehicles slowing to make right-turn maneuvers. Right-turn lanes also improve arterial capacity by removing slower-moving vehicles from the main traffic stream. Transportation agencies must have an understanding of the traffic operational and safety effects of right-turn lanes to determine effectively where right-turn lanes are needed. Therefore, in this research, a computer simulation study of motor vehicles and pedestrians at right-turn lanes was conducted to determine their operational effects. A benefit-cost analysis of right-turn lanes that considered both their operational and safety effects was performed. The research indicates that right-turn maneuvers from a two-lane arterial at an unsignalized intersection or driveway can delay through traffic by 0 to 6 s per through vehicle where no right-turn lane is present. Delays to through traffic due to right turns in the same situation on a four-lane arterial are substantially lower, in the range from 0 to 1 s per through vehicle. Pedestrians at unsignalized intersections or driveways can have a substantial impact on delay to through vehicles due to slowing of right-turning vehicles yielding to pedestrians. Provision of a right-turn lane can reduce pedestrian-related delays to through traffic by as much as 6 s per through vehicle, depending on pedestrian volume. Also presented is an economic-analysis procedure that can identify unsignalized intersections and major driveways at which provision of right-turn lanes is cost-effective.
Avoidance and engagement: Do societal problems fuel political parties’ issue attention?

An important part of political parties’ competition for votes is the extent to which parties avoid or engage the issues that rival parties talk about. Despite a large literature on this topic, it remains largely unknown when parties engage. Drawing on research on political attention allocation and party behaviour, this study argues that societal problems are a central source of issue engagement: The engagement is due to a pressure to not ignore electorally important problems. The analysis shows that issue engagement emerges because parties address the same issues in a negative development. Moreover, and particularly important for issue engagement, parties attend more to a negative development if other parties already attend to the development, particularly at elections. The argument is tested across 16 issue areas through the collection and coding of 5523 press releases from seven parties in Denmark at a quarterly level from 2004 to 2017.
Radio Drama Competition as an Effective Tool to Boost the Motivation and Self-Confidence of Primary and Secondary School English Learners in Hong Kong

In this report, we investigate the use of a radio drama competition to boost motivation, self-confidence, and cooperation in language learning for primary and secondary school students in Hong Kong. The results suggest the radio drama competition had a positive impact on increasing motivation, collaboration, and confidence in language learning. For the study, we used online surveys and interviews with students and teachers who participated in the radio drama competition to examine their perceptions of the competition. We have included the surveys and interview results of two competitions in consecutive years, and both years’ results indicate students had positive views about their experience. Both students and teachers believed the competition enhanced collaboration and teamwork, confidence, and communication skills most. This paper contributes to the literature by shedding light on the pedagogical implications of English teachers incorporating more radio drama and language arts into their classrooms to improve students’ language learning. Well-selected language arts materials could increase students’ language learning process as well as their motivation and self-confidence to learn the target language.
Experiments and Analysis of the Hydraulic Fracture Propagation Behaviors of the Granite with Structural Planes in the Gonghe Basin

Hydraulic fracture (HF) propagation behavior is significant when building enhanced geothermal systems (EGS). HF geometry is closely related to the structural planes (SPs) in hot dry rock (HDR), such as natural fractures (NFs), quartz veins (QVs) and lithologic interfaces (LIs). However, the HF behaviors in HDR have not been well understood, especially the influence of multiple SPs on the HF geometry. To clarify this mechanism, several groups of physical simulation experiments of hydraulic fracturing were conducted to investigate the intersection relationship between the HFs and the SPs. Results show that the HF geometry shows great differences when intersecting with different SPs. In summary, the HF geometry displays four basic patterns, namely, propagation along the SPs, branching, capture, penetration/non‐dilation. The fluctuation degree of the pressure‐time curve and the HF complexity show a positive correlation. The cementing strength of the SP and their different mechanical properties from rock matrix influence the HF behaviors significantly. Therefore, the HF shows diverse geometries when intersecting with the NFs and LIs, while propagating along the QV when intersecting with it. For the complex networks, it is favorable for the HF to penetrate through and dilate several SPs, rather than simply cross or propagate along the SP.
The Significance of Phytochemicals on Periodontal Health

Periodontal disease is an inflammatory disorder of tooth-supporting tissues that affects almost 90% of the population worldwide. The treatment of periodontal disease involved mechanical therapy, surgery, and administration of antibiotics. The high cost of the treatment and bacterial resistance to certain antibiotics regime has led to the search for the alternative treatment to overcome the disease at less cost and side effects. Natural products had been proven to be an important source in developing modern medicine to promote general health. Herbal plant extracts had been widely used in oral health particularly to prevent bacterial plaque adherence and dental caries. In periodontal disease, several studies and reviews have documented that herbal plant extracts had the potential to prevent and treat periodontitis through their active ingredients associated with antimicrobials, antiinflammatory, and anti-oxidant properties. The sources to obtain the herbs are readily available and economical to produce in the market. Some of the herbs had been marketed for public uses in the form of toothpaste and mouth rinses. This review is an attempt to outline the importance of herbal medicine to provide potential effective and economical medicaments for periodontal disease and its significance for further clinical research in the future.
Per se performance and diversity analysis in turmeric (Curcuma longa L.) genotypes for plant and rhizome yield characters

Evaluation of turmeric genotypes is useful to study genetic variation among them and to identify high yielding genotypes. Analysis of genetic divergence in turmeric genotypes is much essential for grouping them based on the observed biometrical and yield traits and to choose the traits responsible for contribution to diversity. Turmeric genotypes were evaluated during 2020 -2021 and 2021 – 2022 and they exhibited wide variation among the observed quantitative traits. Among the turmeric genotypes, CL 95 recorded the highest fresh rhizome yield per plant of 381.8 g followed by CL 258 (341.2 g). CL 95, CL 258, Salem local and CL 197 exhibited better performance for yield and yield contributing traits. Totally six clusters were formed by using Mahalanobis D2 statistics method and genotypes listed in cluster VI were more diverse. Fresh rhizome yield per plant contributed more (41. 99 %) for genetic diversity. The genotypes selected in the present study could used to improve the rhizome yield of turmeric.
