An Online Interactive Video Vignette That Helps Students Learn Key Concepts Of Fermentation And Respiration, Jean A. Cardinale, Dina L. Newman, L. Kate Wright

Articles

Topics related to energy transformation and metabolism are important parts of an undergraduate biology curriculum, but these are also topics that students traditionally struggle with. To address this, we have created a short online Interactive Video Vignette (IVV) called To Ferment or Not to Ferment: That is the Question. This IVV is designed to help students learn important ideas related to cellular respiration and metabolism. Students in various courses across four institutions were assigned the IVV as an out-of-class preinstruction homework assignment. To test the effectiveness of this IVV on student learning, we collected and analyzed data from questions embedded …

Mimicking Prophage Induction In The Body: Induction In The Lab With Ph Gradients, Taylor Miller-Ensminger, Andrea Garretto, Nicole Stark, Catherine Putonti

Bioinformatics Faculty Publications

The majority of bacteria within the human body are lysogens, often harboring multiple bacteriophage sequences (prophages) within their genomes. While several different types of environmental stresses can trigger or induce prophages to enter into the lytic cycle, they have yet to be fully explored and understood in the human microbiota. In the laboratory, the most common induction method is the DNA damaging chemical Mitomycin C. Although pH has been listed in the literature as an induction method, it is not widely used. Here, we detail a protocol for prophage induction by culture under different pH conditions. We explored the effects …

Transformational Game Trial In Nutrition Education, Donna Barwood, Sandra Smith, Margaret Miller, Julie Boston, Martin Masek, Amanda Devine

Australian Journal of Teacher Education

The development of healthy eating habits in adolescents is challenging. Resultantly, health educators are turning to digital devices to engage young people in nutrition education. This paper focuses on the development and evaluation of a computer game (Test Game B) to support healthier food choices. Test Game B was developed at an Australian university and trialled with 72 tertiary student volunteers along with a control game (Control Game A). Both games provided information related to the progression of food along the digestive tract with knowledge of digestion, nutrition, a healthy diet and attitudes to food choice measured before and after …

The Glass Ceiling: Exploring The Leadership Journey Of Men And Women In High-Tech, Shelia Faye Krueger

Dissertations

The literature is replete with evidence of the proliferation of women entering into the workplace, their remarkable progress in attaining higher education, their overrepresentation in professional and management roles, and their placement in CEO leadership positions in certain high-profile S&P 500 global companies. Yet women continue to be noticeably underrepresented in leadership roles, especially in high tech companies. Through the lenses of social constructivist and feminist theories of gender stereotypes, social/gender roles, and role congruity expectations, this instrumental case study was conducted to gain insight into the reasons women are underrepresented in leadership roles in high tech and the ways …

The Effect Of Phytoplankton Properties On The Ingestion Of Marine Snow By Calanus Pacificus, Grace Cawley

Theses

The aggregation of phytoplankton into marine snow provides a mechanism by which smaller particles can coagulate to form larger particles, which can be consumed at various depths or readily transported to the deep ocean and sequestered from the atmosphere on time scales of a thousand years or more. Zooplankton interacting with these large carbon-rich aggregates can obtain nutrition in environments where the phytoplankton size spectrum is small and not directly available, enhancing the possibility of obtaining adequate nutrition in environments dominated by small cells. In addition, interactions between zooplankton and marine snow can result in fragmentation, thus affecting the particle …

Design And Synthesis Of Fluorescent Silica Nanoparticle Conjugates For Metal Ion Sensing Applications, Hank Deuermeyer

Master's Theses

A novel series of fluorescent nanoparticle conjugates were designed and synthesized for the selective turn-off sensing of low concentrations of Cu2+ ion (nM-μM) in 2:1 ethanol:10 mM HEPES (pH 7). Silica nanoparticles (~250 nm) were modified with heterobifunctional polyethylene glycol (PEG) linkers and a third generation PAMAM dendron to function as chelator for Cu2+ ions. The organic dye fluorescein isothiocyanate (FITC) was subsequently conjugated to the dendron to act as a fluorescent sensitizer for the nanoparticle that is quenched upon the binding of Cu2+. Fluorescent nanoparticle conjugates using third and fourth generation PAMAM dendrimers (SNP-G3-FITC and SNP-G4-FITC) were synthesized for …

Membrane-Based Removal Of Ammonia From A Waste Stream And Its Recovery, Philip A. Aligwe

Dissertations

At neutral pH levels, ammonia in aqueous streams exists in two forms: ammonium ion (NH₄⁺) and dissolved ammonia gas molecules (NH₃). Membrane separation serves as a viable option for treatment of ammonia containing effluents. This can be achieved via by stripping NH₃ from an ammonia feed solution at feed solution pH > 11 via hollow fiber supported gas membrane (SGM) or removing NH₄⁺ from an ammonia feed solution at feed solution pH < 7 via liquid or polymeric membranes.

The first study reported here examines the influence of feed volumetric flow rates on outlet NH₃ concentrations in parallel flow …

Graphene Based Barrier Membrane For Gas Separation Processes, Cheng Peng

Dissertations

Novel graphene oxide (GO) flake-based composite lamellar membrane structure is being developed as a potential component of a garment for protection against chemical warfare agents (CWAs) represented here by simulants, dimethyl methyl phosphonate (DMMP) (a sarin-simulant) and 2-chloroethyl ethyl sulfide (2-CEES) (a simulant for sulfur mustard), yet allowing a high moisture transmission rate. GO flakes of dimensions 300-800 nm, 0.7-1.2 nm thickness and dispersed in an aqueous suspension are formed into a membrane by vacuum filtration on a porous polyethersulfone (PES) or poly (ether-ether-ketone) (PEEK) support membrane for noncovalent π-π interactions with GO flakes. After physical compression of such a …

Moisture Permeable Barrier Membranes For Toxic Gases And Vapors, Yufeng Song

Dissertations

Defense against small molecule toxic gases is an important aspect of protection against chemical and biological threat as well as chemical releases from industrial accidents. Current protective respirators/garments cannot effectively block small molecule toxic gases and vapors and retain moisture transmission capability without a heavy burden.

Metal organic frameworks (MOFs) have been used as highly effective adsorbents and catalysts to remove ammonia, cyanogen chloride, and sulfur dioxide from air. A nanopacked bed of nanoparticles of MOF by synthesizing them in the pores of microporous membranes is developed in the study. The submicron scale size of membrane pores ensures a large …

Place Based Education As A Tool For Rural Career Development, David J. Bright

Journal of Counselor Preparation and Supervision

Rural career development is rarely studied despite a large portion of American students attending school in a rural area. Rural career development is affected by factors such as student attachment to place, access to professional role models, local economic development, school funding, and geographic proximity to professional industries and higher education. A Critical Pedagogy of Place (Gruenewald, 2003) empowers students to critical explore the spacial and social constructs of their local area.Given that school counselors are in a unique position as career development and social justice advocates, this article explores the use of a Critical Pedagogy of Place as an …
