Standardization of In-Hospital Cardiac Arrest Recording and Documentation Processes
Get PDFWith the advancement of modern medical practices and technology, the lives of patients have been prolonged, and their outcomes have improved. Patients who were once in intensive care units are now cared for on the medical/surgical ward, while patients who are now in the intensive care units would not have survived a century ago. However, when all measures have been exhausted, a patient may enter cardiac arrest, triggering a cascade of life-saving interventions in an attempt to achieve resuscitation, more commonly known as a “code blue.” The research and implementation of new evidence-based practices has been slow when discussing the processes of code blues, leading to survival rates that have not kept up with those of other medical interventions. Each year, there are over 290,000 in-hospital cardiac arrests (IHCA); of those, only 25% will survive to hospital discharge. The struggle in researching IHCA comes with their infrequency and quick onset, relying on retrospective research. With that, accurate documentation and recording is necessary in order to make significant observations and changes in the code blue process. Interventions that would improve the quality of cardiac arrest recording include incorporating a universal form of documentation across institutions, designating appropriate staff as the recorder in a code blue, adding advanced cardiac life support education to all registered nursing curricula, and establishing a structured environment with proper placement of the recorder during a cardiac event
High-Performance Bio-Based Polyurethane Antismudge Coatings Using Castor Oil-Based Hyperbranched Polyol as Superior Cross-Linkers
Get PDFBio-based antismudge coating, as a substitute for the petroleum-based one, has excellent liquid repellency and self-cleaning ability, which is of great value to keep a coated surface free of contaminants. In this study, we report a facile strategy to fabricate high-performance biobased hyperbranched polyurethane antismudge coatings. More specifically, a castor oil-based hyper-branched polyol was employed as a coating precursor, a hexamethylene diisocyanate trimer was used as the curing agent, and a mono-hydroxyl-terminated poly(dimethysiloxane) (PDMSOH) was introduced as a low-surface-tension lubricant through covalent bonding. Consequently, a highly transparent smooth coating was obtained after the coating solution was completely cured. The coating loaded with 0.5 wt % PDMS-OH exhibited superb liquid repellency and self-cleaning ability, as attested by liquids such as water, hexadecane, peanut oil, pump oil, salt solution, strong acid, and strong alkali solutions that could slide off the coated surfaces cleanly. In addition, even after 1000 writing and erasing cycles, the coating still retained its ability to contract ink traces and the contracted ink could be easily removed with tissue paper. Apart from antigraffiti and antifingerprint performance, the coating applied on tin plate surfaces showed an adhesion grade of 5B and a pencil hardness of 3H and displayed superior corrosion resistance. Furthermore, this mechanically robust coating could withstand 1000 abrasion cycles without sacrificing its ink contraction ability. Therefore, this biobased antismudge coating should provide an alternative avenue for developing green and sustainable functional coatings
Study of Post-Industrial and Post-Consumer Plastics for Degradation Behavior and Material Properties
Get PDFPlastic pollution is a rapidly growing global problem. Current methods of plastics disposal cause even greater environmental impacts. For example, landfills are at capacity, incinerators are increasing greenhouse gases, and microplastics are polluting woodlands and water ways. Thermoplastics recycling of high-density polyethylene (HDPE) has become a focal point in the plastics industry. In this study, we demonstrated the effects that different processing levels have on HDPE physical properties. We processed and analyzed six different plastics: “virgin HPDE”, “internal regrind”, “internal regrind pelletized”, “repro”, “repro with additive”, and “flake”. We first processed the material that was donated to us by Rehrig Pacific into test bars using twin-screw extrusion compounding and injection molding. We then tested mechanical properties such as tensile strength, flexural strength, and impact strength, as well as thermal properties via differential scanning calorimetry, thermogravimetric analysis, and melt flow analysis. Thermal analysis showed no substantial difference between the materials analyzed. All materials had similar mechanical properties with the exception of “repro”, which had higher flexural strength, and lower tensile strength and elongation. Melt flow analysis indicated that “internal regrind pelletized” had slightly lower melt viscosity compared to other materials, suggesting that extrusion may have reduced the material’s molecular weight. Additionally, inclusion of an additive to “repro” improved all material properties we studied. We have demonstrated that differences in post-industrial and post-consumer treatment had an effect on physical properties of plastics, and we can process recycled plastics into plastic parts while gaining a better understanding of processing effects on material properties
Bioinspired Natural Magnolol-Based Adhesive with Strong Adhesion and Antibacterial Properties for Application in Wet and Dry Environments
Get PDFAdhesives are frequently employed in various industries like footwear, electronics, automotive, construction, and furniture. Most of the commonly employed thermoset adhesives contain formaldehyde, such as phenol-formaldehyde (PF) resin and urea-formaldehyde (UF). Although they offer economic benefits, their use has prompted concerns about the production of harmful formaldehyde and phenol. Developing ecologically safe, green, and nontoxic adhesives with superior dry and wet adhesion qualities is extremely important. Barnacles and mussels secrete a hydroxyl-rich dopa, resulting in strong adherence. A biobased adhesive made from magnolol (MAG) and pentaerythritol tetra (3-mercaptopropionate) (PETMP) was created using a thiol-ene click chemistry procedure, inspired by the adhesion mechanism. MP adhesives have excellent binding strength with various substrates like wood, PVC, glass, and metal substrates due to hydrogen bonds created by hydroxyl groups at the interface. They also have a thermosetting network structure. MP\u27s thermosetting network provides superior thermal stability, solvent resistance, and mechanical strength, making it robust in conditions of moisture. To alter the degree of cross-linking in MP, modify the molar ratio of MAG and PETMP. The MP 1 formulation has a high elongation at break (174.27%), making it suitable for use as a flexible adhesive. Furthermore, MAG\u27s natural antibacterial capabilities allow for some antimicrobial and antibacterial adhesion. This article proposes a simple biomimetic technique for using MAG in adhesives
Guided Inquiry Design Lesson: Claim to Fame – Biographies and Facts
Get PDFMy son participated in a Wax Museum project in elementary school that I found fascinating. When presented with the opportunity to create my own project, I was inspired to do something similar. This project was a culmination of the entire graduate course, Information Literacy and Inquiry. Throughout the semester, while utilizing Guided Inquiry Design, I worked on this project which focused on creating a full lesson plan that covers every stage of Guided Inquiry Design while also being built to accommodate different teaching and learning styles. This assignment included several resources, most of which were created by myself using the program Canva. It focuses on library skills, research, and presentation, and is taught by an inquiry team consisting of a classroom teacher, technology teacher, librarian, and art teacher. The Guided Inquiry Design lesson was challenging but, in the end, I learned the value of constructive feedback, taking another look at my ideas and thoughts, and changing directions. This project is also part of my program portfolio as it meets the ISTE Coaching Standard 4.4 – Learning Designer. By creating a lesson plan for Guided Inquiry Design, I created an effective digital learning environment that allows me or any educators to model instructional design principles. This project can easily be modified to meet the needs of learners and educators alike and was built to accommodate the many different learning styles and paces of learners. Educators using this artifact can model the effectiveness of Guided Inquiry Design while also promoting engagement and creativity
