Published: March 2024

Abstract
Extensive research and development has been undertaken in the UK on MarBN steels. These were first proposed by Professor Fujio Abe from NIMS in Japan. Within the UK, progress has been made towards commercialisation of MarBN-type steel through a series of Government funded industrial collaborative projects (IMPACT, IMPEL, INMAP and IMPULSE). As part of the IMPACT project, which was led by Uniper Technologies, boiler tubes were manufactured from the MarBN steel developed within the project, IBN1, and installed on the reheater drums of Units 2 and 3 of Ratcliffe-on-Soar Power Station. The trial tubes were constructed with small sections of Grade 91 tubing on either side of the IBN1 to allow direct comparison after the service exposure. This is the world’s first use of a MarBN steel on a full-scale operational power plant. In September 2018 the first tube was removed having accumulated 11,727 hours operation and 397 starts. This paper reports microstructural and oxidation analysis, that has been undertaken by Loughborough University as part of IMPULSE project, and outlines future work to be carried out.

Abstract
Electron beam melting (EBM) is one of the candidate manufacturing processes for TiAl alloys which have been considered as next generation high-temperature structural materials. The microstructure and mechanical properties of Ti-48Al-2Cr-2Nb (48-2-2) alloy bars fabricated using EBM were investigated, with a particular focus on the effect of processing parameters such as input energy density and building direction. We observed that the microstructure of the alloy bars fabricated using EBM depends strongly on the processing parameters used during the fabrication process of alloy. In particular, the alloy bars fabricated under appropriate processing parameters have a unique layered microstructure composed of duplex regions and equiaxed γ-grain regions (γ bands). Because of their fine microstructure and deformable soft γ bands, the alloy bars with the unique layered microstructure exhibit higher strength and higher ductility at room temperature (RT) than that of cast alloys. In addition, the alloy bars fabricated at an angle between the building direction and the loading axis of 45° show good fatigue properties at RT even without hot isostatic pressing treatment.
The Status of Continued Development of Heavy Section Castings in 9%Cr Steels and Nickel Alloys for High Temperature Applications

Published: March 2024

Abstract
To meet worldwide emission targets many Government policies either avoid the use of coal burning plant for future energy production, or restrict emissions per kilogram of coal consumed beyond the capability of most conventional plant. As a result this has accelerated current worldwide developments of steel and nickel alloys for coal-fired plant to operate at temperatures in excess of 625°C. Within the UK a modified 9%Cr steel has been developed which is based on the MarBN steel first proposed by Professor Fujio Abe of NIMS Japan, and has been designated IBN-1. The steel is modified by additions of, typically, 3% cobalt and tungsten with controlled additions of boron and nitrogen. While development of 9%Cr steels has continued since the last EPRI high temperature material conference in 2016 (Portugal), parallel developments in nickel alloy castings for even higher temperature and pressure applications have also continued. This paper summarises the latest developments in both of these material types.

Published: March 2024

Abstract
Effects of microstructure constituents of α2-Ti3Al/γ-TiAl lamellae, β-Ti grains and γ grains, with various volume fractions on room-temperature ductility of γ-TiAl based alloys have been studied. The ductility of the alloys containing β phase of about 20% in volume increases to more than 1% as the volume fraction of γ phase increases to 80%. However, γ single phase alloys show very limited ductility of less than 0.2%. Microstructure analysis have revealed that intragranular fracture along γ/γ grain boundary occurred in γ single phase alloy whereas it does not along β/γ interphase in alloys containing β phase. In addition, local strain accumulations along β/γ interphase have been confirmed. The present results, thus, confirmed the significant contribution of β phase, especially the existence of β/γ interphase to enhancement of the room-temperature ductility in multicomponent TiAl alloys.

Published: March 2024

The presented results determine the functional activity of platelets in 35 patients diagnosed with chronic generalized periodontitis (CGP). Dystrophic changes in the periodontium were assessed by measuring pathological periodontal pockets and the Ramfjord index. The level of inflammation in periodontal tissues was determined by PMA and PBI indices.
The evaluation of platelet functional activity in patients with CGP was conducted before and after combined treatment, including the administration of "Tanakan" (orally 120mg/day for 1 month). It was observed that an increase in adhesive-aggregational platelet function is typical for periodontal patients (degree of aggregation% and rate of aggregation%). Additionally, the parallel investigation of coagulation hemostasis in this patient group showed no significant changes in clotting time of plasma citrate. It was found that the prescribed "Tanakan" medication promotes inhibition of platelet aggregational activity, thus improving microcirculation in periodontal pathology.
The Correlation between Fetuin-A Levels And Nafld Fibrosis Score (NFS)
Authors: Hafiz Syaifullah Siregar  
Published: March 2024

Abstract. Fetuin-A is a plasma glycoprotein expressed in the liver. Fatty liver accumulation because changing fetuin-A expression leads to nonalcoholic fatty liver disease (NAFLD). The benefits of serum fetuin-A as a predictor of fibrosis biomarkers in NAFLD patients remain unclear. Non-invasive scoring system predicting fibrosis among patients with NAFLD is the NAFLD fibrosis score (NFS). Objective. This study aims to find the correlation between circulating fetuin-A levels and NFS in NAFLD patients. Methods. Eighty subjects (male, 52; female, 26) followed this cross-sectional study. NAFLD is diagnosed with an abdominal ultrasound. The serum levels of fetuin-A measured by ELISA. NFS is used to identify the probability of fibrosis in subjects. The correlation between Fetuin-A levels and NFS was determined using Pearson correlation tests. A p-value < 0.05 was significant. Results. There was significant difference in fetuin-A levels (p < 0.001) between NAFLD degree I (421.71 pg/mL), NAFLD degree II (494.88 pg/mL), and NAFLD degree III (692 pg/mL). The NFS low probability score in 46 subjects and NFS indeterminate score in 34 subjects. Serum concentrations of fetuin-A correlate significantly with NFS (r = 0.478, p < 0.001). Conclusion. There is a positive correlation between serum levels of fetuin-A and NFS.

Published: March 2024

Abstract. Introduction: Whitish lesion over the oropharyngeal mucosal lesion is traditionally attributed to benign lesions such as leukoplakia, oral candidiasis or lichen planus, which can be diagnosed through histopathological examination. Yet, performing a biopsy is prudent in all cases of persistent whitish lesions to rule out a more sinister pathology such as malignancy. Herein, we report an incidental finding of a whitish lesion in the soft palate of a gentleman who presented with otalgia and otorrhea, which turned out to be basaloid squamous cell carcinoma (BSCC). Therefore, we highlight the importance of thorough, meticulous and complete Ear, Nose and Throat examinations in all patients as they enable early diagnosis of a sinister pathology in this patient.

Authors: Mahmoud Hoda 
Published: March 2024

<p>Ultra-high performance concrete is a new generation of concrete that supersedes traditional concrete. The new material is self-consolidated, and the present research focuses on the impact resistance of UHPC under impact loading. Four specimens in the form of simply supported beams with identical dimensions and steel reinforcement ratios are tested under low-velocity impact loading. The specimens are 140 mm in diameter and 2000 mm in length. </p>
<p><br></p>
<p>The experimental results revealed that the concrete type significantly affects the lateral impact resistance. UHPC specimen deform in a more ductile manner, and there is no severe local buckling in the steel tube. UHPC specimen effectively restricts the indentation and local bulking within a highly localized region around the impact point and limits the deformation of the steel tube. UHPC material is easy to mix and demonstrates superior impact resistance under lateral impact load.</p>
The Dark Side of Work-life Policies: Examining the Impact of Co-worker Childcare Policy Usage on Work Anxiety
Authors: Silva Katia Osso Lourenco da 
Published: March 2024

<p>Work-life policies (WLPs) are tools employees may draw on to better manage and balance their work and life demands. While WLP research generally shows WLPs positively impact the individuals that use the policy, there is growing evidence to suggest that WLPs may also negatively impact other employees. Drawing from the theory of role dynamics and social role theory, we examine the indirect effect of co-worker childcare policy usage (CUCP) on work anxiety via work-role overload (WRO), as well as the impact of gender on this indirect relationship. Findings from a three-wave field study (n = 357) reveal: (1) CUCP positively relates to work anxiety via WRO for men, and (2) CUCP negatively relates to work anxiety via WRO for women. Theoretical and practical implications are discussed. </p>

Background & objectives: Urinary tract infection (UTI) is one of the most common infectious diseases affecting all age & sex groups, causing significant morbidity & mortality with a substantial economic burden. Due to the irrational empiric use of antibiotics, resistance is increasing at an alarming rate. Bacteria causing UTIs & their antimicrobial susceptibility pattern varies among different areas & changes frequently over time. This study aimed to identify microorganisms causing UTI at a private hospital in the southern part of Bangladesh & to determine their sensitivity pattern towards commonly used antibiotics. Methods: A cross-sectional study was conducted in the clinical pathology & microbiology laboratory at Islami Bank Hospital (IBH), Khulna during the period of January’2021 to July’2021. Clean catch midstream urine samples (MSU) from 221 clinically suspected UTI cases of all age & sex groups were included in the study. Uropathogens were isolated & identified by standard microbiological techniques & susceptibility was determined by Kirby Kirby-Bauer disc diffusion method. Results: Among 221 suspected UTI cases, 108 (48.8%) were positive for urine culture, of which 103 (95.37%) showed antimicrobial growth. The majority 75 (69.4%) of the culture-positive cases were female. E. coli 50(44.24%) was the most predominant bacterial isolate, followed by Klebsiella 18(15.92%) & Enterococcus 16(14.15%). All Isolated gram-positive cocci (GPC) showed very high sensitivity to Vancomycin (83.3% to 100%), Linezolid (87.5% to 100%) & moderate sensitivity to Meropenem (66.7% to 75%). However, they showed relatively lower sensitivity to Ciprofloxacin, Doxycycline, Gentamicin, and Amoxiclav & very poor sensitivity to Nitrofurantoin (31.3% to 50% only). Levofloxacin had relatively better sensitivity against GPC (S. aureus- 83.3% & CONS- 75%), except Enterococcus. All gram-negative bacilli (GNB) showed a very good sensitivity towards Amikacin & Meropenem, ranging from 77.8% to 100%. E. coli & Pseudomonas were highly sensitive to Piperacillin-Tazobactam (90% & 88.9% respectively). GNB were poorly sensitive to commonly used 3rd generation cephalosporins, Azithromycin, Amoxiclav & Ciprofloxacin. Except for Pseudomonas & Klebsiella, Levofloxacin showed relatively good sensitivity against other GNB. Nitrofurantoin showed lower sensitivity against GNB, except for Pseudomonas (66.7%) & Enterobacter (75%). Conclusion: E. coli remains the most predominant uropathogen. Vancomycin, linezolid, Levofloxacin & Meropenem were very effective against GPC whereas Amikacin, Piperacillin- tazobactam & Meropenem showed good responses against GNB. Empiric antibiotics must be selected based on the current antibiogram of uropathogens in a particular area to prevent the increasing trends of antimicrobial resistance.

Stunting merupakan kondisi dimana terjadi gangguan pada masa pertumbuhan dan perkembangan akibat dari kuranngaya gizi kronik dan infeksi berular. Stunting dipengaruhi oleh beberapa faktor antara lain, kondisi soisal ekonomi, gizi ibu saat hamil, kurangnya asupan gizi pada bayi ataupun karena infeksi bakteri/virus pada bayi. Kondisi ini menyebabkan balita akan mengalami penghambatan pertumbuhan fisik dan kognitif yang berakibat pada bentuk fisik tubuh dan pola pikir anak dalam penyelesaian masalah. Kejadian gizi buruk dan gizi kurang kini menjadi masalah baru yang hadir dimasyarakat. Upaya penanganan gizi buruk pada balita dan anak telah banyak dilakukan di seluruh dunia termasuk Indonesia, mengingat tingginya kasus gizi buruk yang dilaporkan. Berdasarakan data RISKESDAS tahun 2007 sampai dengan 2013 terjadi peningkatan data gizi buruk (0,31%) dan gizi kurang (0,96%) di Indonesia. Hingga tahun 2022 masih terdapat 27,7% angka kejadian stunting di Sulawesi tenggara. Hal ini perlu mendapatkan perhatian untuk menekan prevalensi stunting yang sejalan dengan Perpres nomor 72 tahun 2021 tentang percepatan penurunan stunting. Kasus stunting juga erat kaitanya dengan kecacinganan. Kejadian cacingan berulang pada anak dapat menyebabkan malnutrisi. Stunting dapat menyebabkan cacingan karena merupakan salah satu faktor resiko kecacinganan.
A cost-sensitive deep neural network-based prediction model for the mortality in acute myocardial infarction patients with hypertension on imbalanced data

Published: March 2024

Background and objectivesHypertension is one of the most serious risk factors and the leading cause of mortality in patients with cardiovascular diseases (CVDs). It is necessary to accurately predict the mortality of patients suffering from CVDs with hypertension. Therefore, this paper proposes a novel cost-sensitive deep neural network (CSDNN)-based mortality prediction model for out-of-hospital acute myocardial infarction (AMI) patients with hypertension on imbalanced data.MethodsThe synopsis of our research is as follows. First, the experimental data is extracted from the Korea Acute Myocardial Infarction Registry-National Institutes of Health (KAMIR-NIH) and preprocessed with several approaches. Then the imbalanced experimental dataset is divided into training data (80%) and test data (20%). After that, we design the proposed CSDNN-based mortality prediction model, which can solve the skewed class distribution between the majority and minority classes in the training data. The threshold moving technique is also employed to enhance the performance of the proposed model. Finally, we evaluate the performance of the proposed model using the test data and compare it with other commonly used machine learning (ML) and data sampling-based ensemble models. Moreover, the hyperparameters of all models are optimized through random search strategies with a 5-fold cross-validation approach.Results and discussionIn the result, the proposed CSDNN model with the threshold moving technique yielded the best results on imbalanced data. Additionally, our proposed model outperformed the best ML model and the classic data sampling-based ensemble model with an AUC of 2.58% and 2.55% improvement, respectively. It aids in decision-making and offers a precise mortality prediction for AMI patients with hypertension.
