In partnership with NASA, National Institute of Aerospace (NIA) and Bennett College for Women, University of Maryland Eastern Shore (UMES) hosted the 11thPre-service Teacher program. The program had two significant components: a) A national Pre-service Teacher Conference (PSTC) held at Alexandria, VA, during February 16-18, 2006, that drew participation from HBCUs (Historically Black Colleges and Universities), HSIs(Hispanic Serving Institutions), TCUs ( Tribal Colleges and Universities) and majority universities with significant minority enrollment and b) An intensive two week Preservice Teacher Institute (PSTI) in the summer for a relatively small group of pre-service teachers held at NASA Langley for inspiring future K-12 teachers in the fields of mathematics, science, and technology education fields. This paper will focus on a robotics activity designed by the primary author for the PSTI. While designing the activity the technology education standards as proposed by ITEA (International Technology Education Association)/CTTE (Council on Technology Teacher Education) and ISTE (International Standard for Technology Education) were consulted and incorporated in the lesson. For the primary author, who is an engineering educator the experience revealed the confusion that prevails in the teacher education field with regard to "technology education" and its evolving standards. It is important for engineering educators to get involved and facilitate K-12 curricula development efforts based on these standards, and provide clarity to how "technology education" in the K-12 is related to vocational technology, instructional technology, mathematics, sciences, engineering and engineering technology. © American Society for engineering Education, 2007.

Applied Mathematical Modelling 2024年 133卷 41-64页

Using an asymptotic method, this article deals with flexural-gravity wave scattering with undulating bottom topography, including the effect of uniform currents. The interest in this problem lies in developing second-order solutions using the Fourier transform, which minimises the error gap between first and second-order solutions. The present method allows the physical processes involved in the sea-bed topography, uniform current, plate-covered surface, and wave interaction to be studied. Specifically, we observe Bragg resonance between the flexural-gravity waves and the bottom ripples, which are associated with the reflection of incident wave energy. We examine the effects of wave current and emphasise how crucial the asymptotic expansion method is to the emergence of the current response. We demonstrate that bottom topography dominates the effects of Bragg resonance for depth Froude numbers valued at 0.8 or less. Further, most reflected wave components have their frequencies shifted by the current, and wave action conservation causes reflected wave energy to be enhanced for following currents. Using the Joint North Sea Wave Observation Project spectrum and the discrete Fourier transform, the theory derived in the frequency domain is shown in the time domain to analyse wave propagation through the whole system. © 2024

Although much has been learned about the fibrillization kinetics, structure and toxicity of amyloid proteins, the properties of amyloid fibrils beyond the saturation phase are often perceived as chemically and biologically inert, despite evidence suggesting otherwise. To fill this knowledge gap, we examined the physical and biological characteristics of human islet amyloid polypeptide(IAPP) fibrils that were aged up to two months. Not only did aging decrease the toxicity of IAPP fibrils, but the fibrils also sequestered fresh IAPP and suppressed their toxicity in an embryonic zebrafish model. The mechanical properties of IAPP fibrils in different aging stages were probed by atomic force microscopy and sonication, which displayed comparable stiffness but age-dependent fragmentation, followed by self-assembly of such fragments into the largest lamellar amyloid structures reported to date. The dynamic structural and toxicity profiles of amyloid fibrils and plaques suggest that they play active, long-term roles in cell degeneration and may be a therapeutic target for amyloid diseases.

Microbially induced calcite precipitation (MICP) is an emerging geotechnical improvement technology that has received wide attention from researchers around the world. The applications of MICP in geotechnical field including soil improvement, surface resistance from erosion, coastal protection, and slope stabilization have been investigated by previous researchers. This paper presents a review on application of MICP for slope stabilization. Three subtopics were selected to be discussed: application of native bacteria, modified MICP methods, and field-scale studies. This review reveals that (1) MICP has the potential for slope stabilization;(2) native bacteria are ideal for use in MICP for application in slopes located in regions with variable cold climatic conditions;(3) to improve the effectiveness of MICP for slope stability, traditional MICP needs be modified;(4) MICP appears to have the potential to be one of the future landslide mitigation strategies since it works effectively in the field-scale test. Additionally, the recommended further researches in MICP for slope stabilization are: (1) Study on the other types of native bacteria for diverse environmental condition is required;(2) to discover the best slope stabilization method, the combination of MICP and other traditional slope stabilization techniques should be investigated;(3) it is critical to investigate the effectiveness of the MICP technology for slope stabilization under various conditions in the field. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Gastric or duodenal ulcers can lead to upper gastrointestinal (GI) bleeding. Infection with Helicobacter pylori (H. pylori) is one of the most common infections in the world and can cause both gastric ulcers and gastric cancer. The treatment aims to eradicate H. pylori and treatment with antibiotics has made it possible to cure gastric ulcers. The most common complication of untreated peptic ulcer disease is bleeding (hematemesis, melena, and anemia), while perforation occurs in a smaller proportion of patients. In some individuals, the infection causes mucosal changes with increasing age that lead to atrophy and intestinal metaplasia. It is believed that atrophy and especially intestinal metaplasia are a prerequisite for the most common form of gastric cancer, adenocarcinoma. There is presently a demand for an alternate treatment devoid of the current strategies drawbacks including recurrence, resistance and antibiotic abuse. The current workhighlights the possibility of bee product-based treatments for preventing and eliminating H. pylori infestation. Sci-finder, Google Scholar, PubMed, scienceDirect, Web of science, and Scopus were used for literature screening. Terms and keywords, i.e. “helicobacter pylori”, “epidemiology”, “chemotherapy”, “honey”, “propolis”, “bee venom”, “bioactive compounds”, and “mechanism of action” were used in the search. Bee products are important alternatives that have been utilized for treating many ailments due to their diverse biochemical and biological characteristics. Various mechanisms, such as direct antibacterial, antioxidant, anti-inflammatory, and wound healing capacities, are proposed to explain the potential effect of bee products against H. pylori. The bee product's metabolites have a role in the adherence of H. pylori to stomach epithelial cells. The disruption of bacterial cell membranes and the inhibition of virulence factors are the two mechanisms behind the bee product's promising therapeutic applications against H. py
