Polyethylene Oxide and Silicon-Substituted Hydroxyapatite Composite: A Biomaterial for Hard Tissue Engineering in Orthopedic and Spine Surgery

Background: Tissue engineering and biomaterials have made it possible to produce bone therapy for orthopedic and spine disorders. The aim of this research is to produce a unique polyethylene oxide/silicon-substituted hydroxyapatite composite that can be used as a scaffold for hard tissue engineering in orthopedic and spine procedures. Results: Scanning electron microscope photographs revealed that 5% PEO, 5% PEO/0. 2 percent Si-HA, and 5% PEO/0. 6 percent Si-HA fibers had been produced successively. The comparison between the mean fiber diameters of 5% PEO/0. 2% Si-HA and 5% PEO/0. 6% Si-HA revealed to be highly different. As the Si-HA content increased, some fibers were being contaminated with Si-HA particles that were not fully integrated into the polymer matrix. Conclusions: Electrospinning assisted in the production of a new biomaterial for a hard tissue scaffold. PEO/Si-HA fibers are manufactured with the intention of mimicing bone's extracellular matrix.

An Extended Constructive Alignment Model in Teaching Electromagnetism to Engineering Undergraduates

It's difficult to start abstract concepts to students from applied fields. This paper describes a conceptual model that identifies learning goals in three levels of Engineering Electromagnetics. This model gives students more access to the learning objectives and improves the visibility of the learning and grading processes. The main aim of this conceptual model is to encourage students to study with the end in mind.

Networks and Emotions in Cooperative Work: A Quasi-Experimental Study in University Nursing and Computer Engineering Students

We can examine the reticular structures that have been created and find patterns of collaboration among university students through social network analysis. The main aim of this research was to investigate the effects of interdisciplinary collaborative research between nursing and computer engineering students on the collaboration and friendship networks, emotions, and performance of the participants. The most central people in the network corresponded with those who believe positive emotions were most in their academic environment, while the less prominent ones resembled those who highlighted negative emotions.

FORENSIC ENGINEERING SURVEYS WITH UAV PHOTOGRAMMETRY AND LASER SCANNING TECHNIQUES

This paper aims to demonstrate the use of emerging technologies in the field of forensic engineering. Particularly, the use of UAV photogrammetry and laser scanning is compared to the traditional methods of surveying an accident site. Surveys must be carried out quickly, carried out in a short time, and completed with such precision that the most crucial data is not lost when the scene is no longer preserved. These requirements can be satisfactorily fulfilled by a combination of new surveying techniques such as UAV photogrammetry and laser scanning.

Engineering actinomycetes for biosynthesis of macrolactone polyketides

Actinobacteria is the most popular manufacturer of natural products with pharmaceutical importance. The bulk of these BGCs include polyketide synthase or non-ribosomal peptide synthase, or a mixture of both PKS and NRPS. Macrolides compounds contain a central macro-lactone ring adorned with several functional groups in their chemical structures. In this report, we have discussed several ways for generating a variety of macrolide cascades from either enzyme or cellular levels in actinobacteria species strains, either native or heterologous producer strains.

First year engineering students: Perceptions of engineers and engineering work amongst domestic and international students

Students enter engineering school without knowing the truth of either their degree program or engineering career, as well as a lack of motivation and commitment are all potential reasons for this. The study involved over 1,100 first year engineering students enrolled in a common first-year unit. Respondents were coded using the Engineers Australia graduate curriculum as a framework, and this paper presents findings from the most diverse cohort of students, of whom 49% were international students with English as their second language. The study revealed differences between international and domestic students' opinions of self and career skills, which may be related to self-confidence and self-confidence. The study shows that comparative and educational history of international students may help determine how different cohorts of international students self-appraise and how they integrate learning with their future careers.
