Visual Literacy Of Molecular Biology Revealed Through A Card-Sorting Task, Dina L. Newman, Hannah Spector, Anna Neuenschwander, Anna J. Miller, Lauren Trumpore, Leslie Kate Wright

Articles

Visual literacy, which is the ability to effectively identify, interpret, evaluate, use, and create images and visual media, is an important aspect of science literacy. As molecular processes are not directly observable, researchers and educators rely on visual representations (e.g., drawings) to communicate ideas in biology. How learners interpret and organize those numerous diagrams is related to their underlying knowledge about biology and their skills in visual literacy. Furthermore, it is not always obvious how and why learners interpret diagrams in the way they do (especially if their interpretations are unexpected), as it is not possible to “see” inside the …

From Fully-Supervised Single-Task To Semi-Supervised Multi-Task Deep Learning Architectures For Segmentation In Medical Imaging Applications, S M Kamrul Hasan

Effect Of Blank Moisture Content On Forming Behaviour And Mechanical Properties Of Paperboard Tray Packages, Arvo Niini, Lena Berthold, Tobias Müller, Panu Tanninen, Jens-Peter Majschak, Juha Varis, Ville Leminen

Journal of Applied Packaging Research

Tray blanks were moisturised to study the effect of different blank moisture content levels on forming behaviour and mechanical properties of paperboard tray packages. The blank moisturisation was done by spraying water to the blanks before their three-dimensional (3D) forming. The trays were 3D formed by press forming or deep drawing. Visual quality and punch force values were used as indicators to evaluate the forming behaviour of the trays. The mechanical properties of the trays were investigated with compression, torsion, and storing tests. A high blank moisture content reduced the punch force, and the elevated blank moisture was connected to …

Adjusting/Modifying Assignments To Support Students With Learning Disabilities While Engaging In Ngss Science And Engineering Practices And Inquiry-Based Learning, Shannon Morago Dr.

Journal of Science Education for Students with Disabilities

Effective science instruction involves opportunities for all students to do science, including engaging in the NGSS Science and Engineering Practices through inquiry-based learning.

The stability of the juvenile delinquency-free equilibrium of the model is examined using the standard non-linear dynamical systems theory technique. We carried out a data fitting based on real-life data from the New York State Criminal Justice Services. The research result reveals that the formulated model conforms with the available data and …

Analysis Of Strain Correction Procedures For Single Fiber Tensile Testing, Amy Engelbrecht-Wiggans, Amanda L. Forster

Articles

Accurate strain measurement for single fibers is critical for many engineering applications. Typically, the crosshead displacement is used to calculate strain when performing mechanical testing, however there are complicating factors: slack in the specimen or slipping/seating in the grips, other grip effects, and load frame compliance. These are addressed in various testing standards for single fibers, such as ASTM Standards D3822, “Standard Test Method for Tensile Properties of Single Textile Fibers” and C1557, “Standard Test Method for Tensile Strength and Young's Modulus of Fibers”.

Drawing From The Past, Pengpeng Chen

Theses

Drawing From the Past is a short, 3D animated film that portrays the different thoughts about drawing between two generations and is based on my personal experience. Some art students get less encouragement from their families than other students. In Asian traditional thinking, majoring in art was not the correct career direction, which is correct in that period， because of the economy. Majoring in art means students need to pay more money than other majors. In addition, art is not necessary for some people who worry about food. In the previous period, many people worry about their lives. That means …

Side-Channel Attacks And Countermeasures For The Mk-3 Authenticated Encryption Scheme, Peter Fabinski

Theses

In the field of cryptography, the focus is often placed on security in a mathematical or information-theoretic sense; for example, cipher security is typically evaluated by the difficulty of deducing the plaintext from the ciphertext without knowledge of the key. However, once these cryptographic schemes are implemented in electronic devices, another class of attack presents itself. Side-channel attacks take advantage of the side effects of performing a computation, such as power consumption or electromagnetic emissions, to extract information outside of normal means. In particular, these side-channels can reveal parts of the internal state of a computation. This is important because …

Effect Of Plasma Treatment On Soil Degradation Of A Biodegradable Mulch Film, Swapnil Bhattacharya

Theses

Biodegradable Mulch Films (BMFs) offer a sustainable alternative to traditional non-degradable PE mulch films. However, their slow rate of biodegradation can lead to plastics accumulation in the soil. In this study, a commercially available BMF based on polybutylene adipate co-terephthalate (PBAT) and polylactic acid (PLA) is examined. Here the effects of gliding arc plasma treatment on the bulk and surface properties, as well as its soil degradation behavior, is studied. An increase in surface oxygen containing species and hydrophilicity was observed following plasma treatment. Only a small hydrophobic recovery was noted over 30 days. No changes in the bulk polymer …
