Abstract: This study investigates the combustion characteristics of hydrogen catalysed biodiesel (HCB) ignited gasoline in an optical engine using the Reactivity Controlled Compression Ignition (RCCI) combustion model. The experiment uses a single injection strategy to determine the optimum injection timing for gasoline ignition by varying the HCB injection timing (-30 to -15° CAATDC) and the ratio of high to low reactivity fuel energy (10% to 30%), to investigate the gasoline premix ratio, and to analyse the flame development characteristics. The results indicate that as the HCB energy ratio increases, the in-cylinder pressure and heat release rate increase significantly, and the in-cylinder combustion temperature improves significantly. As the injection timing is delayed, the combustion phase shifts back, and when the injection timing is close to the upper stop, the in-cylinder combustion pressure and heat release rate increase first increase and then decrease. Based on the results, it can be concluded that optimising the HCB injection timing and energy ratio can effectively control the distribution of the fuel-air mixture in the combustion chamber, thereby improving combustion efficiency and emission performance. By strategically adjusting the injection timing, an ideal balance between fuel stratification and flame propagation can be achieved, which ultimately improves the overall combustion process. The results of this study provide valuable insights for the further development of combustion control strategies and contribute to the development of more efficient and environmentally friendly engine technologies.
Gut microbiota predicts the diagnosis of ulcerative colitis in Saudi children
Authors: El Mouzan Mohammad , Al Sarkhy Ahmed , Assiri Asaad
Published: March 2024

BACKGROUND

Ulcerative colitis (UC) is an immune-mediated chronic inflammatory condition with a worldwide distribution. Although the etiology of this disease is still unknown, the understanding of the role of the microbiota is becoming increasingly strong.

AIM

To investigate the predictive power of the gut microbiota for the diagnosis of UC in a cohort of newly diagnosed treatment-naïve Saudi children with UC.

METHODS

The study population included 20 children with a confirmed diagnosis of UC and 20 healthy controls. Microbial DNA was extracted and sequenced, and shotgun metagenomic analysis was performed for bacteria and bacteriophages. Biostatistics and bioinformatics demonstrated significant dysbiosis in the form of reduced alpha diversity, beta diversity, and significant difference of abundance of taxa between children with UC and control groups. The receiver operating characteristic curve, a probability curve, was used to determine the difference between the UC and control groups. The area under the curve (AUC) represents the degree of separability between the UC group and the control group. The AUC was calculated for all identified bacterial species and for bacterial species identified by the random forest classification algorithm as important potential biomarkers of UC. A similar method of AUC calculation for all bacteriophages and important species was used.

RESULTS

The median age and range were 14 (0.5-21) and 12.9 (6.8-16.3) years for children with UC and controls, respectively, and 40% and 35% were male for children with UC and controls, respectively. The AUC for all identified bacterial species was 89.5%. However, when using the bacterial species identified as important by random forest classification algorithm analysis, the accuracy increased to 97.6%. Similarly, the AUC for all the identified bacteriophages was 87.4%, but this value increased to 94.5% when the important bacteriophage biomarkers were used.

CONCLUSION

The very high to excellent AUCs of fecal bacterial and viral species suggest the potential use of noninvasive microbiota-based tests for the diagnosis of unusual cases of UC in children. In addition, the identification of important bacteria and bacteriophages whose abundance is reduced in children with UC suggests the potential of preventive and adjuvant microbial therapy for UC.
The Voice of the Non-Human: Scientific Knowledge, It-Narratives and Fiction in the Long Eighteenth Century
Authors: Mattana Alessio
Published: March 2024

This article examines the connection between early scientific ideas and It-Narratives in Britain over the long eighteenth century. A set of It-Narratives - fictional texts narrated by, or centred on, non-human entities like things or animals - will be read against the attempt to detect the voice of natural things by a number of early-modern experimental and natural philosophers. It will be argued that, although causal links are hard to prove, there is a degree of epistemic vicinity between these early scientific ideas and It-Narratives. In particular, it will be shown how in both disciplines fiction helped contemplate the possibility that non-human knowledge is more reliable than human-derived one.
El discurso bajo sospecha en la dramaturgia española contemporánea: una mirada de Sanchis Sinisterra a María Velasco
Authors: Castro Filho Claudio
Published: March 2024

Aunque las dramaturgias gestadas en España desde los años 70 hasta este comienzo de siglo conformen un campo discursivo plural y estéticamente heterogéneo, podemos hallar en diferentes autoras y autores cierta similitud en cuanto a la problematización discursiva y, en concreto, al valor de la palabra. Unas veces buscada, otras diagnosticada, la crisis de la palabra —su insuficiencia o inocuidad, su potencia bélica o adictiva, etc.— atraviesa poéticas dramatúrgicas como las de Angélica Liddell, María Velasco, Alberto Conejero, Juan Mayorga o, antes, José Sanchis Sinisterra. En este artículo, indagaremos en la plasmación estética de la crisis de la palabra (o del discurso bajo sospecha) que se manifiesta, quizás como síntoma o rasgo generacional, en obras recientes de la dramaturgia española. Por un lado, observaremos cómo en este reducido corpus se recuperan debates sobre la crisis autoral heredados del siglo XX (con énfasis en la filosofía del teatro) y cómo, a nivel histórico, sigue en boga —pese a las ya casi cuatro décadas de democracia— una relación traumática con la memoria y con la legitimidad del relato.
Krínein, entre la vida y la muerte. Alternativas discursivas en el relato sobre violencia de género
Authors: Calabrese Giuliana
Published: March 2024

Según el Diccionario Crítico Etimológico Castellano e Hispánico, la etimología de “crisis” tiene su origen en el ámbito médico derivando del griego κρίνειν (krínein: separar, decidir); en la medicina de la antigüedad clásica, dicha separación indicaba un punto crucial y decisivo debido a un cambio brusco o profundo, hasta el punto de separar la vida de la muerte. En la actualidad, la supuesta “crisis de la masculinidad” y la violencia de género nos sitúan cada día más en un peligroso punto de separación entre la vida y la muerte que, desde la literatura, se pretende abordar en este trabajo desde un punto de vista del lenguaje y de construcción del discurso en obras como La feliz y violenta vida de Maribel Ziga (2020), de Itziar Ziga, o Violencia (2020), de Bibiana Collado Cabrera, sin dejar de mencionar obras de referencia publicadas en los últimos años y no solo en el ámbito peninsular, como por ejemplo El invencible verano de Liliana (2021), de Cristina Rivera Garza. Desde la etimología de “crisis” que remite directamente al punto de separación entre la vida y la muerte, la difusión y el análisis de obras literarias que exploran la violencia machista proporcionan por lo menos dos grandes posibilidades: en primer lugar permiten alejarse de la dimensión del sujeto contemporáneo acorralado y solitario en su dimensión de individualidad en crisis para que, en cambio, sea posible reconocerse y encontrar respaldo en un colectivo; en segundo lugar, la literatura que se acerca a ese daño problematiza el arquetipo de mujer o cuerpo feminizado maltratado como víctima pasiva, sin voz ni agencia para pensar y debatir acerca de la autodefensa.

OUTCOMES OF ROTATIONAL ATHERECTOMY IN CALCIFIED PROXIMAL LEFT ANTERIOR DESCENDING (LAD) LESIONS IN THE CONTEXT OF TRIPLE VESSEL DISEASE
Authors: ASLAM K , IQBAL E , KHAN FR , SAJJAD W , KHAN MS
Published: March 2024

Percutaneous coronary intervention (PCI) has become more complex with the advancement of medical devices. One such device is the rotational atherectomy (RA), which uses a rotating diamond-coated burr to modify calcified lesions. This makes it easier to deliver balloons and stents to specific lesions. However, there is a lack of literature regarding the success of RA in calcified proximal 'left anterior descending (LAD) lesions' following PCI. To address this gap, a study was conducted to evaluate the clinical outcomes of RA in calcified proximal LAD lesions in triple vessel disease (TVD). The study included 112 patients who underwent PCI using RA between February 2022 and November 2022 at Lady Reading Hospital, Peshawar. Data was collected using a standard report structure, including operative and follow-up details and medical and demographic features. Retrospective data was collected using medical records and interviews with patients or doctors. The ethical committee approved the study. The participants had an average age of 68.4± 0.45 years, with 85 men (75.8%) and 40 (35.7%) with diabetes mellitus. The technical success rate was 97.6%, with 20 individuals (17.8%) experiencing significant adverse cerebral and cardiac events while hospitalized. At 1.5 years, 25 (22.3%) TVFs had occurred. Independent variables such as current smoking, chronic renal disease, history of cerebrovascular attack, left ventricle ejection fraction, and left central disease were assessed to predict TVF. Based on the results, the investigation showed that rotational atherectomy in calcified proximal LAD lesions had promising success rates.

Authors: Dong Qiuran , He Yifan
Published: March 2024

The aim of this research paper is to provide a comprehensive comparison between Riemann integral and Lebesgue integral. Integration is described as the inverse process of differentiation, which is used to determine the original function. Riemann integration is a specific type of definite integral applied to find the exact area under a function graph between two limits in a closed interval. Lebesgue integration, on the other hand, provides a more generalized framework for integration theory. Integrals are essential in mathematical modelling and analysis tools. Studying and comparing the similarities and differences between these two integration methods can help us better understand the essence and properties of integrals, so as to more accurately apply integration methods to solve practical problems. This paper provides a systematic analysis of the basics, definitions, concepts, and properties of Riemann integral and Lebesgue integral. Reasoning, proofs, and examples are consolidated to explain the properties and characteristics of these two integral methods. Finally, this paper explores the strengths and limitations of each integration methods, summarising their advantages and applicability to practical problems and providing insights into their respective computational methods and applicability in different contexts.

An in-depth analysis and derivation of extremum conditions based on gradient information
Authors: Honghao Yang , Guizhong He
Published: March 2024

This paper explores the necessary conditions for extremum in both constrained and unconstrained problems by extracting fundamental principles of constraint conditions. We provide a precise geometric understanding of the Lagrange Multiplier, prioritizing analytical insight. Beginning with a geometric interpretation of the gradient, we leverage the expansion of functions and their images to comprehend extremum and detail the Lagrangian derivation process.We expand the base vectors of the constraint surface into those of the full space and use a transition matrix to assess the function's extremum. This demonstrates how the second derivative matrix is transformed into its full-space representation to discern extrema in optimization problems. Additionally, we introduce incremental variables to optimize the second-order derivative matrix in full space, providing a novel perspective to solve extremal necessary conditions.
Thermal-Hydraulic performance of microchannel heat sink designed with counter-flow and different groove shape
Authors: Liu Ruize
Published: March 2024

Microchannel heat sink is a potential procedure for scatter heat as a result of its little size and high effectiveness. Thermal resistance and pumping power are two significant parameters to assess the behavior of microchannel heat sink. In this review, heat transfer and fluid behavior have been concentrated mathematically in a microchannel heat sink with the counter stream and different shape of the groove. Four unique cases are discussed in this paper, microchannel heat sink with rectangular groove (R-MCHS), microchannel heat sink with circular groove (C-MCHS), microchannel heat sink with triangular groove (T-MCHS), and straight microchannel heat sink (S-MCHS). Three-dimensional numerical simulation is conducted with the Reynolds number, Re, shifting from 100 to 500 with expanding 100 for each step. As the coolant, Single-stage fluid water streams in the heat sink. The thermal and hydraulic performance of these cases are evaluated by comparing the average temperature of the solid domain, Nusselt number, Thermal Resistance, and Pumping Power. Contrasted with the S-MCHS, the thermal performance of MCHSs with grooves is increased, and the Nusselt number increased at the furrow area. Likewise, the pumping power is bigger for all cases with grooves contrasted and S-MCHS. In all grooved cases, R-MCHS has the lowest average temperature on the bottom surface and the highest average temperature in the solid domain. The C-MCHS has the least thermal resistance for all Re between 100 to 500. In light of the component, the plan standards to move toward the presentation of inclination are proposed.
Improving liquid cancer biopsy through computer-aided microfluidic device design based on the tubular pinch effect and Deans flow
Authors: Recce Alexander
Published: March 2024

A blood test, called a liquid biopsy is being developed by several research groups for the early detection of cancer. The key challenge in this process is enrichment, or isolation, of the small number of cancer cells in blood serum from other cells. This study uses numerical simulations to design devices that advance the state of art in the enrichment of circulating cancer cells. In particular, the lift forces acting on neutrally buoyant small spherical particles in a Poiseuille flow bounded by a wall are modelled using numerical computation. Specifically, we explore the influence of the Reynolds number, distance to the wall, and particle size on these lift forces, building upon previous research on the Segre-Silberberg effect. By validating the mechanism by which particles concentrate at specific positions within the fluid, we confirm the existence of the Segre-Silberberg effect in this system. Subsequently, we apply a customized 3D model of a filtration device to investigate the Segre-Silberberg effect and Deans effect in a non-Poiseuille flow, which can be applied in liquid cancer biopsy. Our results demonstrate that this flow pattern could potentially be used to separate cancer cells from the mean flow. Finally, we apply the flow separation mechanisms in microfluidic design through a rapid 3D design and computational fluid dynamics (CFD) verification cycle. The popular spiral microfluidic design does not demonstrate strong flow separation pattern in our tests, while the sinusoidal design shows much more promise. Further research is needed to empirically evaluate these designs.

Published: March 2024

This research aims to examine the challenges, the condition of religious material understanding, and effective strategies and methods of religious education for students at SMPLB Shafa Mojokerto. The study employs a qualitative approach with a case study method. Data collection is conducted through interviews, observations, and documentation of the school principal, three teachers, and three students. The research findings indicate that the main challenges faced by religious teachers are the disparity in students' understanding levels, resource limitations, and the difficulty of effective communication with students with special needs. Nevertheless, the maximum efforts of teachers and school support manage to overcome these various obstacles. Overall, the students' understanding and acceptance of religious material are relatively good, although some students still encounter difficulties in grasping specific topics. Effective learning strategies include implementing an inclusive approach, active and contextual learning, optimizing the role of parents and the family environment, and emphasizing the internalization of religious values in shaping students' character. Recommendations include improving the availability of learning resources and support facilities, providing teacher training, and continuously evaluating and refining religious education methods to adapt to students' evolving needs.
