The designed nature and controlled, one-pot synthesis of DNA origami provides exciting opportunities in many fields, particularly nanoelectronics. Many of these applications require interaction with and adhesion of DNA nanostructures to a substrate. Due to its atomically flat and easily cleaned nature, mica has been the substrate of choice for DNA origami experiments. However, the practical applications of mica are relatively limited compared to those of semiconductor substrates. For this reason, a straightforward, stable, and repeatable process for DNA origami adhesion on derivatized silicon oxide is presented here. To promote the adhesion of DNA nanostructures to silicon oxide surface, a self-assembled monolayer of 3-aminopropyltriethoxysilane (APTES) is deposited from an aqueous solution that is compatible with many photoresists. The substrate must be cleaned of all organic and metal contaminants using Radio Corporation of America (RCA) cleaning processes and the native oxide layer must be etched to ensure a flat, functionalizable surface. Cleanrooms are equipped with facilities for silicon cleaning, however many components of DNA origami buffers and solutions are often not allowed in them due to contamination concerns. This manuscript describes the set-up and protocol for in-lab, small-scale silicon cleaning for researchers who do not have access to a cleanroom or would like to incorporate processes that could cause contamination of a cleanroom CMOS clean bench. Additionally, variables for regulating coverage are discussed and how to recognize and avoid common sample preparation problems is described.

In this paper, I examine the procedures used by Andreas Vesalius for conducting public dissections in the early sixteenth century. I point out that in order to overcome the limitations of public anatomical demonstration noted by his predecessors, Vesalius employed several innovative strategies, including the use of animals as dissection subjects, the preparation and display of articulated skeletons, and the use of printed and hand-drawn illustrations. I suggest that the examination of these three strategies for resolving the challenges of public anatomical demonstration helps us to reinterpret Vesalius's contributions to sixteenth-century anatomy. © 2015 The Author.

In this article I examine the origins and progression of the practice of vivisection in roughly the first half of the sixteenth century, paying particular attention to the types of vivisection procedures performed, the classical sources for those procedures and the changing nature of the concerns motivating the anatomists who performed them. My goal is to reexamine a procedure typically treated as something revived by Vesalius from classical sources as a precursor to early modern discoveries by placing the practice of vivisection in its sixteenth-century context. There were a variety of reasons for employing vivisection in the sixteenth century, including exploring the differences between living and dead bodies, considering how parts of the body worked, and advocating the entirely new idea of the pulmonary transit. By exploring the discussions of Berengario, Niccolò Massa, Vesalius, Colombo and Juan Valverde I try to elaborate on these various reasons and their origins. © 2012 Springer Science+Business Media B.V.

High quality formative feedback is an integral component of a fruitful learning experience. Pedagogical approaches are needed to increase the quality of instructor feedback and train students to interpret and appropriately respond to feedback. To develop research-informed approaches, students' thinking from receipt of feedback to action can be explored through an analysis of documented works, such as written feedback and students' iterative solutions. However, such approaches do not reveal the whole story of their interactions with feedback.The purpose of this study is to explore student team responses to teaching assistants' (TAs') written feedback while revising their mathematical model. The research question that guides this study is: How do student teams respond to feedback and convey their ideas from their team discussions in their documented works? We report case findings from two first-year engineering student teams' responses to TA feedback on a Model-Eliciting Activity (MEA). The teams were videotaped while working to revise their draft. The findings from this data are supported by documented works (written feedback and students' iterative solutions) along with student interviews. In trying to understand the complexity of students' learning experience, this study provides insights into how students respond to TA feedback, specifically how they interpret feedback, budget time, and effectively report the outcomes of team discussion. Moreover, findings imply that TAs need to better identify misconceptions and target feedback appropriately. © American Society for Engineering Education, 2013.

Secondary schools are in a prime position to introduce students into careers in Supply Chain Management and Logistics. However, these teachers often lack any practical experience in the field and lack the understanding to communicate the latest trends, technologies, and career opportunities to their students. The teachers also lack understanding in how to connect these high-demand careers to their current course offerings in technology or business management. The NSF Award "Technology-Based Logistics: Leveraging Indiana's Role as the Crossroads of America" (Awards 1304619 and 1304520) specifically addresses these concerns through building a pipeline of educational curriculum that begins with secondary education and continues through community college and four-year institutions. Through dual credit opportunities, strong linkages to potential supply chain careers are reinforced beginning at grade 10. A combination of teacher professional development, curriculum development and support, and national certifications creates an opportunity for students to enter the supply chain management and logistics industry sector. Entry points in this sector are available at a wide variety of skill levels, including high school diploma, certificate programs, and two year and four year degree programs. This paper will document best practices used in training secondary educators on supply chain management topics, including simulation and game-based instruction. It will also describe the secondary to post-secondary educational pathway, a career opportunity matrix and present associated curriculum and articulation agreements. © American Society for Engineering Education, 2016.

In a freshman introductory plastics course at a mid-western state university and a technical college, students were introduced to several metal and plastic materials properties and were taught how some of these properties could be determined using testing procedures described in the American Society for Testing and Materials (ASTM) standards. One such standard is designated D-638-14, titled "Standard Test Method for Tensile Properties of Plastics," which states that "test specimens shall be prepared by machining operations, or die cutting, from materials in sheet, plate, slab, or similar form. Specimens can also be prepared by molding the material to be tested." Missing from the list of test specimen preparation methods are 3D-priting techniques. In this study, students prepared test specimens of Acrylonitrile-Butadiene-Styrene (ABS) plastic material by 3D-printing according to ASTM D638 Type 1 specimen specifications. These test specimens were compared to specimens prepared from ABS sheets by laser cutting to determine if 3D printing had a significant effect on the tensile properties of ABS test specimens. The test specimens prepared by laser cutting served as the control test specimens; this option replaced the use of injection molded specimens as the control test specimens because of the higher costs of the latter specimens. The fused-deposition-modeling 3D-printing machines used in this study were Makerbot" Replicator 2x, Lulzbot" TAZ 5, and Stratasys' Dimensions". The Instron materials testing machine, model 5967, was used in testing the tensile properties of the ABS specimens.

If you knew no one with a mental illness, what would mold your perceptions of someone with a mental illness? A movie character, a television actor, a description from a friend? Each of these explanations has been given to me by nursing students beginning their mental health nursing clinical rotation. Reconsideration of the limited amount of mental health education in nursing school is urgent. As we become more engrossed as a society in television and movies, the result appears to be a deceptive idea of what true mental illness entails. This piece shares personal insight from a mental health nursing educator and the transformation she witnesses in her students after a mental health clinical rotation.

There is nothing more important to the success or failure of a business than its customers. According to a report in Fortune Magazine, one-fourth of all customers are lost every year due to subpar service or poor quality. In order to succeed, an organization must focus on satisfying or exceeding the requirements, expectations, needs, and preferences of customers. Good customer service is all about bringing customers back. Since the purpose of the changes would eventually benefit everyone, the real problem was not the change itself, but rather a lack of discussion, inclusion, and negotiation in which winners could compensate those who saw themselves as losers in order to make everyone whole. Additional studies have revealed that prolonged exposure to artificial light decreases antibody activity, increases infections and colds, and results in depression. Creating workplaces that reduce these impediments must, therefore, be considered an integral part of sustainable work practices.
