Authors: Badr Marwa J. , Ismael Mohammed Q.
Published: August 2024

Sustainable waste management aims to reduce the consumption of raw materials by reusing as many RCA materials as possible. This research aims to evaluate the influence treated and untreated recycling coarse aggregate on the hot asphalt mixture’s properties using asphalt grade (40-50) modified with 3% Polyphosphoric Acid (PPA). RCA was used in different proportions (25%, 50%, 75%, and 100%) as a substitute for raw coarse aggregate; the effect of treatment on improving the RCA’s quality was tested. Volumetric properties associated with the Marshall test for asphalt concrete were tested. Tensile strength ratio (TSR) and index of retained strength (IRS) measurements were used to assess the moisture effect. The study findings indicated that 25% RCA is the maximum amount of RCA from concrete that should be added to asphalt mixtures. This percentage recorded the highest values for TSR and IRS, with the ideal modified asphalt content of 4.86%. Based on the results of this study, asphalt concrete's durability will generally grow with RCA use, while its susceptibility to moisture will increase. However, treated RCA improved the results compared to untreated RCA. Using asphalt modified with polyphosphoric acid remarkably improved the asphalt mixtures’ performance and reduced the asphalt consumption rate.

Serum phosphorus levels as a predictor and severity marker for mechanical ventilation in adults versus elderly patients – A cross-sectional study
Authors: Ambali Anand P , Tomar Priyanka , Shivanand L K
Published: August 2024

Objectives

Mechanical ventilation (MV) is a supportive therapy for patients with acute respiratory failure. Studies have shown direct relationship between serum phosphorus on admission and risk of respiratory failure requiring MV. This study aims to determine admission serum phosphorus level’s ability to predict severity in 64 mechanically ventilated patients among two groups: Group A was designated to adults (<60 years of age) and Group B to elderly (60 years or older) admitted to the critical care unit (CCU). Study Design: It is a cross-sectional study.

Material and Methods

Data were collected from 64 adults admitted to CCU. The Sequential Organ Failure Assessment (SOFA) score and serum Phosphorus level on admission were assessed. Patients with Diabetic Ketoacidosis, Head Trauma, Renal Failure, Hyper or Hypoparathyroidism, Leukaemia, and Lymphoma were excluded.

Results

The study had 32 subjects in each group. The commonest indication for mechanical ventilation was Poisoning (31.25%) in Group A and Cerebrovascular Accident (34.37%) in Group B. The common complication among the study group was ventilator- associated pneumonia (14.06%). Out of 64 patients requiring mechanical ventilation, nine patients had hypophosphatemia, and eighteen had hyperphosphatemia. In the case of hypophosphatemia, 100% and in hyperphosphatemia, 55.5% mortality was observed.

Conclusion

Altered serum phosphorus levels on admission can be a potential indicator for requiring MV and mortality. Both hypophosphatemia and hyperphosphatemia are potential risk factors for the development of respiratory failure. Also, age-related variation in phosphorus levels has not shown any association with the outcome.

Authors: Iqbal Hamna Mariyam , Samad K. Abdul , Nair Pradeep S.
Published: August 2024

Objectives:

Methotrexate (MTX) is one of the oldest conventional agents used for management of chronic plaque psoriasis, and apremilast (APM) is a recent small molecule for the treatment of chronic plaque psoriasis. The objective of this study was to compare the clinical response of patients with chronic plaque psoriasis treated with MTX versus APM.

Materials and Methods:

This is a 1½ year descriptive observational study of all new chronic plaque psoriasis patients. The sample size was 64 (31 in MTX group and 33 in APM group). Sixty-four patients diagnosed with chronic plaque psoriasis were treated with MTX or APM. The patients were evaluated for therapeutic outcome by psoriasis area and severity index (PASI) score at 4 weeks, 12 weeks, and 24 weeks. The efficacy of drugs was compared using PASI 75. The data obtained from the patient was entered in Microsoft Excel and analyzed using the Statistical Package for the Social Sciences software.

Results:

Out of the 64 patients, 31 were treated with MTX and 33 patients were treated with APM. At 12 weeks, 35.5% of patients receiving MTX group achieved PASI 75 whereas only 9% of patients achieved PASI 75 in APM group which was found to be statistically significant (P = 0.01). The PASI 75 was achieved by 93.5% of patients in the MTX group and 87.9% of patients in the APM group with no statistical significance at 24 weeks.

Conclusion:

The MTX and APM demonstrated equal efficacy in the treatment of chronic plaque psoriasis at the end of 24 weeks.

Published: August 2024

Giant retinal tears (GRTs) are rare and challenging complications of rhegmatogenous retinal detachment (RRD) that necessitate intricate surgical management. This study aimed to systematically review and analyze the functional outcomes, anatomical success rates, and complications associated with surgical interventions for GRTs in adults. A comprehensive literature search was conducted using electronic databases, including PubMed, Embase, Web of Science, and the Cochrane Library, from 2002 to February 2024. We included original research articles with diverse study designs involving adult patients (≥18 years) who underwent surgical treatment for GRTs. The identified interventions included pars plana vitrectomy, scleral buckling, combined procedures, and pneumatic retinopexy. The outcome measures included detailed descriptions of pre-and post-operative visual acuity, initial and final anatomical success rates, and main post-operative complication descriptions. After screening 4104 records, 22 studies were ultimately included in the study. The total sample comprised 1607 participants, with a male predominance. Surgical interventions have resulted in varying improvements in post-operative visual acuity. Notably, the anatomical success rates ranged from 70% to 100%, with microincision vitrectomy surgery (MIVS) platforms currently being the predominant gold-standard surgical method for GRT-associated RRDs. The postoperative complications identified were proliferative vitreoretinopathy (PVR), epiretinal membrane (ERM) development, hypotony, cataracts, uveitis, and foreign body reaction. Subsequent examination revealed poor pre-operative visual acuity, pre-operative PVR, and younger age, which presented challenges that impacted the outcomes. Despite limited evidence, this systematic review offers valuable insights into the diverse outcomes and difficulties associated with surgical approaches and interventions for GRTs in the adult population. This study highlights the significance of management strategies and calls for additional research in this field.
Textile Development (TED) Method – a new method for the sustainable development of new textile products
Authors: Bettermann Isa , Mukherjee-Kleiber Debolina , Heesemann Rahel , Gries Thomas
Published: August 2024

The textile field is diverse and encompasses products intended for technical and non-technical applications. The product diversity in the textile domain has led to various product development approaches. This paper describes a product development method for textile products that is generally applicable. In the so-called Textile Development (TED)-Method, the textile surface manufacturing process is determined in the product development process. In this way, it is possible to develop in an open, target-oriented way and independent of an existing supplier or machine park. By using correlation matrices, a broad design field is considered and specific solutions are extrapolated that lead to the desired product without lengthy iteration series. Thus, the TED-Method additionally represents a resource-saving product development without renouncing a broad design field. Three different development examples of the TED-Method are presented, thus demonstrating the open and comprehensive use of the method
Strong asymmetry in near-fault ground velocity during an oblique strike-slip earthquake revealed by waveform particle motions and dynamic rupture simulations
Authors: Kearse Jesse , Kaneko Yoshihiro , Nozuka Yoshito , Milliner Christopher , Hsu Ya-Ju , Avouac Jean-Philippe
Published: August 2024

The 2022 Mw 7.0 Chihshang (Taiwan) earthquake, captured by almost a dozen near-fault strong-motion seismometers, high-rate GPS and satellite data, offers a rare opportunity to examine dynamic fault rupture in detail. Using dynamic rupture simulations, we investigate the particle motions recorded at near-fault strong-motion and 1 Hz GPS stations surrounding the main asperity. Some of these stations were as close as 250 m from the fault trace as determined by sub-pixel correlation of Sentinel-2 images. Our model reproduces the observed strong asymmetry in the ground motions on either side of the fault rupture, which results from along-dip spatial variability in rake angle on the steeply dipping fault (70°) at shallow depth (2 km). Observed near-fault, pulse-like fault-parallel ground velocity larger than fault-normal velocity can be explained by a model with a sub-shear rupture speed, which may be due to shallow rupture propagation within low-velocity material and to free surface reflections. In addition, we estimate a slip-weakening distance Dc of ~0.7-0.9m from strong-motion seismogram recorded at Station F073, which is located ~250 m from the fault rupture, and the results of dynamic rupture modeling. The inferred Dc is similar to other empirically derived estimates found for crustal earthquakes. These results have important implications for near-fault ground-motion hazard.

Published: August 2024

Under the background of the big data era, the education of big data majors is undergoing a profound teaching reform and innovation. With the increasing role of big data technology in analysis and decision-making, updating and expanding the teaching content of big data majors has become particularly important. In the era of big data, modern enterprises have put forward new and higher demands for big data talents, which not only include traditional data analysis skills but also knowledge of data visualization and information technology. To address these challenges, big data education needs to reform and innovate in the development and utilization of teaching content, methods, and resources. This paper proposes teaching models and reform methods for big data majors and analyzes corresponding teaching reforms and innovations to meet the requirements of the new development of big data majors. The traditional classroom teaching method is no longer sufficient to meet the learning needs of students, and more dynamic and interactive teaching methods, such as case studies, flipped classrooms, and project-based learning, are becoming increasingly essential. These innovative teaching methods can more effectively cultivate students’ practical operation skills and independent thinking while allowing them to better learn advanced knowledge in a real big-data environment. In addition, the paper also discusses the construction of big data processing and analysis platforms, as well as innovative teaching management and evaluation systems to improve teaching quality.

Analogy helps students find solutions to problems that involve new knowledge by referring to previously learned knowledge. Analogical argumentation plays a crucial role in supporting solutions to interconnected problems. Analogical argumentation itself is defined as the process of analyzing information from two similar and interconnected problems to provide logical reasons to justify conclusions. This research aims to describe the analogical argumentation of high school students on predictive analogy problems. This study uses a descriptive qualitative approach. The research subjects are three 10th-grade students from a public high school in Bojonegoro, selected based on the criteria of the source problem 1) claim being supported by grounds and warrant, 2) claim being supported by grounds, warrants focusing on congruence, and backing, 3) claim being supported by grounds, warrants focusing on square rotation, and backing. The data from the analogical argumentaion task and interviews were analyzed using predefined indicators by the researcher. The research findings indicate that students' analogical argumentation begins with identifying information, questions, and identical concepts between the two problems. Then, students make assumptions about the structure of the target problem in relation to the source problem, search for similarities in geometric properties, and discover relationships between the questions in both problems. Students engage in appropriate argumentation based on the source problem to predict conclusions for the target problem. They construct grounds and warrants based on the structure of analogical argumentation. Students tend not to double-check their answers because they are already confident with their stated conclusions.

Based on the results of the research, it can be concluded that the critical thinking skills of (1) male and female students with high mathematical ability met the indicators of interpretation, analysis, evolution (on argument proof, because in argument assessment only male students met the sub-indicator), inference, and explanation. Male students did not fulfill the indicators of self-regulation, while female students did. (2) Male and female students with moderate mathematics ability met the indicators of interpretation, inference, and explanation. Male students did not fulfill the indicators of analysis and self-regulation, while female students did. However, both did not fulfill the evaluation indicator. (3) Male and female students with low mathematics ability have many differences in critical thinking skills. Male students did not fulfill the indicators of interpretation, analysis, explanation, and evaluation. However, the self-regulation indicator is fulfilled. While female students fulfill the indicators of interpretation and analysis. Female students did not fulfill the indicators of evaluation, explanation, and self-regulation.

Technological developments in the world of education are growing rapidly, one of which is electronic modules (e-modules) which can be alternative learning media used in the teaching and learning process. This study aims to develop Android-based interactive e-module learning media that meets valid, practical, and effective criteria. It uses the ADDIE model, which consists of five stages: analysis by performance, students, curriculum, and media. The design stage involves material preparation, instrument manufacturing, flowcharts, and storyboards. The development phase involves interactive e-modules based on Android, media validation, revision, and limited trials. The implementation phase involves implementing the e-module for class VII students at SMPN 26 Surabaya. The Evaluation stage is carried out by analyzing the results of the research that has been done.The results of the development of this media are suitable for use based on predetermined criteria. The first criterion is that learning media has been declared very valid with a score of 82.7% for the design, a score of 81.2% for the material, and the validity of the test questions which get a score of 86.1%. The second criterion is that learning media is declared practical by the percentage of student response questionnaires of 77.7%. The third criterion is that the learning media is declared effective and there is a significant difference between the results of student scores before and after using the e-module as evidenced by the average N-Gain score of 0.79.

Problem solving competence is the ability of a person to carry out the problem solving process. This is he one of the skills a student must master after learning mathematics. Different students have different solutions when solving problems in statistical context. This is because each student has a different level of intelligence to solve problems. This intelligence is called Adversity Quotient (AQ). There are three AQ levels for him: Climber, Camper and Climber. The purpose of this study is to illustrate the ability of AQ to solve contextual problems of statistical material. This study was a descriptive study with a qualitative approach and was conducted in her 8th grade consisting of 3 of her students with different AQ levels. The research equipment used consisted of ARP, TPMS, and an interview guide. The results of this study suggested that, at the level of problem understanding, subjects who abandoned the problem were able to retell in their own language, which was different from that of the subjects who abandoned the problem, giving the language of the question a different meaning. During the planning stage, professional mountaineers understand the relationship between problems and statistical concepts and daily life and develop a very coherent and clear plan, whereas professional mountaineers and promoters develop a plan with a good understanding of the relationship between statistical concepts and daily life. During the execution phase of planning, professional movers and campers can find the right answers, but professional movers can also find the wrong answers. In the hindsight stage, the climber double-checks to reach the correct conclusion, but the climber and the climber can make fairly accurate conclusions without double-checking. Therefore, it is important for students and teachers to know problem-solving skills in the context of statistical material in order to improve comprehension and information comprehension in making logical conclusions using statistical ideas derived from statistical information about everyday problems.

Students' low understanding of relations between quadrilaterals indicates a problem in the construction process of quadrilateral concepts. The construction process of students can be assisted by the application of APOS theory in geometry, besides that it can develop abstract geometry knowledge through the use of appropriate geometry representations. Some studies don’t involve technology in the construction process, which makes researchers interested in implementing GeoGebra software. This research is qualitative research that aims to reveal the students' construction process about relations between quadrilateral assisted by GeoGebra. The subjects of this study were three 8th-grade SMP Negeri 1 Tuban. To reveal the students' construction process regarding the relations between quadrilateral, the researcher made a knowledge test, construction test, and conducted interviews for students with poor, intermediate, and high knowledge improvement. The results of this study revealed that with the help of GeoGebra (1) the subject is able to determine the characteristics of each quadrilateral in a more complex manner and specializes the quadrilaterals, (2) the subject is able to determine several quadrilateral relations but the subject has not been able to use the ability to classify quadrilaterals. There are obstacles faced by the subject such as lack of subject ability and limited time when processing GeoGebra.
