Mechanically Tuned 3 Dimensional Hydrogels Support Human Mammary Fibroblast Growth And Viability, Kathryn Woods, Catlyn Thigpen, Jennifer Peyling Wang, Hana Park, Abigail Hielscher

PCOM Scholarly Works

BACKGROUND: Carcinoma associated fibroblasts (CAFs or myofibroblasts) are activated fibroblasts which participate in breast tumor growth, angiogenesis, invasion, metastasis and therapy resistance. As such, recent efforts have been directed toward understanding the factors responsible for activation of the phenotype. In this study, we have investigated how changes in the mechanical stiffness of a 3D hydrogel alter the behavior and myofibroblast-like properties of human mammary fibroblasts (HMFs).

RESULTS: Here, we utilized microbial transglutaminase (mTG) to mechanically tune the stiffness of gelatin hydrogels and used rheology to show that increasing concentrations mTG resulted in hydrogels with greater elastic moduli (G'). Upon encapsulation …

Guitar Music Manuscripts In The Senate Library Of Madrid: The CancióN PatrióTica De La Alianza And Its Experimental Notation, Ricardo Aleixo

Soundboard Scholar

The modest collection of manuscripts of guitar music preserved in the Senate Library of Madrid seems to provide a representative sampling of the types of guitar repertoire circulating in Spain in the late eighteenth and early nineteenth centuries. Despite its small size, this corpus contains the most typical genres of the period— namely, two chamber music works for guitar with bowed string instruments, by Federico Moretti and Antonio Ximénez, a guitar duet by Pierre-Jean Porro, a solo guitar work by the mysterious señor D. G. G. M. A., and two songs with guitar accompaniment, one by Francisco Xavier Moreno and …

Moving Bed Biofilm Reactors: Evaluation Of Geometry, Attachment Surface Material And Biofilm Populations On The Uptake Of Ammonia And Synthetic Organic Contaminants In Wastewater., Patrick D. Mclee

Civil Engineering ETDs

Plastic biofilm carriers are used in biological wastewater treatment to encourage the attachment and retention of microorganisms that metabolize pollutants. The following research was conducted to better understand how different characteristics of the biofilm carrier affect the treatment performance of the attached biofilms in moving bed bioreactors. Lab scale reactors were used in this study to grow nitrifying biofilms in reactors with contrasting and controlled conditions. The effect of surface geometry on nitrification performance was evaluated by testing commercially available moving bed bioreactor media that contrast in physical design, and by varying operational parameters. Additionally, mature biofilm from a similar …

Quantifying The Effect Of Construction Site Factors On Concrete Quality, Costs And Production Rates, Jorge L. Santamaria

Civil Engineering ETDs

Factors affecting concrete can be categorized as structured factors or unstructured factors. The first group of factors consists of those related to the production process of concrete including water-cement ratio, properties of raw materials and mix proportions. Unstructured factors or construction site factors are related to labor skills and local conditions during the construction process of a project. Concrete compressive strength as a quality metric, costs and production rates may be affected significantly by such factors while performing concrete operations at the jobsite. Several prior studies have investigated the effect of structured factors on concrete. However literature is limited regarding …

Passing, Paul Kelley

The Transdisciplinary STEAM+ Journal

Passing is a Site-specific public installation assembled with plastic and an iPad. At its center, the iPad displays a video loop of a human image repeatedly walking in and out of the frame. The work maintains my foundational interest in having the viewer slow down to have a more thoughtful and absorptive experience with the work and surrounding space – continuing my practice of challenging viewer’s expectations and putting them in a position to stop and question.

3d Printing – An Insider’S Perspective, Siddharth Sah

The Transdisciplinary STEAM+ Journal

The 3D printing market globally is still at its infancy, - or some might argue that there isn’t really a market yet. The knowledge of 3D printing design is still largely limited to engineering design – not product design. At MakeWhale, we are constantly pushing the boundaries of the application of 3D printing technology to consumer products resulting in a beautiful mix of technology and art.

Science Theater As Steam: A Case Study Of "Save It Now", Christopher D. Davidson, Willard Simms

The Transdisciplinary STEAM+ Journal

What are the markers of a successful STEAM program? How and when can educators be reasonably sure that an interdisciplinary unit or project, rich in both the sciences and the arts, has delivered on its implicit promise – by adding value to a student’s education in ways that are beyond the scope of traditional discipline-specific learning? I attempt to address this question with a case study of Theatre of Will’s “Save It Now,” a pilot program for 4^th, 5^th and 6^th graders at eight Los Angeles public schools that integrates theater arts, music and the STEM …

Science And Sentiment: Affecting Change In Environmental Awareness, Attitudes, And Actions Through The Daily Nature Project, Elizabeth D. Haynes Poronsky

The Transdisciplinary STEAM+ Journal

Knowledge about what motivates pro-environmental behavior is important to organizations that seek to encourage environmental stewardship. Research suggests that targeting emotions and beliefs about nature can be more effective in changing environmental actions than increasing knowledge. Daily Nature, a site on the social media platform Facebook, features a daily nature photograph, a quote from a notable historical person and a related lyrical written passage. The popularity of this site lends credence to the appeal of interdisciplinary formats, and underscores the benefits of encouraging emotional and aesthetic ties to nature.

Getting Girls In Stem & The Dangers Of Forgetting That Science Is Art - Someone Made It Up, Heidi Therese Dangelmaier, Camilla Hermann

The Transdisciplinary STEAM+ Journal

Encouraging girls to participate in STEM is a hot topic that has captured the concern of the world’s academic, business and scientific communities. The intention is noble, however the strategies being deployed are reinforcing the very bias society seeks to eliminate. If we wish to advance our evolutionary journey as a species, a shift from “feeling sorry for disadvantaged girls” to “fearing STEM without girls’ reformation” is imperative. This piece discusses the rise to an initiative to redesign culture: Girlapproved.
