Line Tension And Its Influence On Droplets And Particles At Surfaces, Bruce M. Law, Sean P. Mcbride, Jiang Yong Wang, Haeng Sub Wi, Govind Paneru, Santigo Betelu, Baku Ushijima, Youichi Takata, Bret Flanders, Fernando Bresme, Hiroki Matsubara, Takanori Takiue, Makoto Aratono

Physics Faculty Research

In this review we examine the influence of the line tension s on droplets and particles at surfaces. The line tension influences the nucleation behavior and contact angle of liquid droplets at both liquid and solid surfaces and alters the attachment energetics of solid particles to liquid surfaces. Many factors, occurring over a wide range of length scales, contribute to the line tension. On atomic scales, atomic rearrangements and reorientations of submolecular components give rise to an atomic line tension contribution satom (1 nN), which depends on the similarity/dissimilarity of the droplet/particle surface composition compared with the surface upon which …

Masculinity And Disproportionate Risk Of Contact With The Criminal Justice System: Findings From A Select Sample Of Low-Income Black Males In New York City, Michael G. Pass

Dissertations, Theses, and Capstone Projects

Official statistics document that Black males experience disproportionate contact with the criminal justice system (CJS). Existing theory and research suggest that this contact may be attributed to unique attributes of Black masculine behavior. Utilizing a meta-analysis of Black masculinity studies and content analysis of narratives from a select sample of Black males, ages 19-50, the current study examines the similarities and differences between the construction and performance of normative or traditional masculinity, as measured by Mahalik et als’ CMNI and the attributes of Black masculinity as defined in the literature. A goal of the study was to assess whether Black …

Soluble Factors Secreted By Endothelial Cells Allow For Productive And Latent Hiv-1 Infection In Resting Cd4+ T Cells, John Henry Morris, Tran Nguyen, Abuoma Nwadike, Mackenzie L. Geels

University Faculty Publications and Creative Works

In vitro, it is difficult to infect resting CD4+ T cells with human immunodeficiency virus type 1 (HIV), but infections readily occur in vivo. Endothelial cells (ECs) interact with resting CD4+ T cells in vivo, and we found previously that EC stimulation leads to productive and latent HIV infection of resting CD4+ T cells. In this study, we further characterize the interactions between EC and resting T cells. We found that resting CD4+ T cells did not require direct contact with EC for productive and/or latent infection to occur, indicating the involvement of soluble factors. Among 30 cytokines tested in …

Incorporating Sociocultural Phenomena Into Ecosystem-Service Valuation: The Importance Of Critical Pluralism, Carena J. Van Riper, Adam C. Landon, Sarah Kidd, Patrick Bitterman, Lee A. Fitzgerald, Elise F. Granek, Sonia Ibarra, David Iwaniec, Christopher Raymond, David Toledo

Environmental Science and Management Faculty Publications and Presentations

Ecosystem-services scholarship has largely focused on monetary valuation and the material contributions of ecosystems to human well-being. Increasingly, research is calling for a deeper understanding of how less tangible, nonmaterial values shape management and stakeholder decisions. We propose a framework that characterizes a suite of sociocultural phenomena rooted in key social science disciplines that are currently underrepresented in the ecosystem-services literature. The results from three example studies are presented to demonstrate how the tenets of this conceptual model can be applied in practice. We consider the findings from these studies in light of three priorities for future research: (1) complexities …

Forest Management Scenarios In A Changing Climate: Trade-Offs Between Carbon, Timber, And Old Forest, Robert M. Scheller, Megan K. Creutzburg, Melissa S. Lucash, Stephen D. Leduc, Mark G. Johnson

Environmental Science and Management Faculty Publications and Presentations

Balancing economic, ecological, and social values has long been a challenge in the forests of the Pacific Northwest, where conflict over timber harvest and old-growth habitat on public lands has been contentious for the past several decades. The Northwest Forest Plan, adopted two decades ago to guide management on federal lands, is currently being revised as the region searches for a balance between sustainable timber yields and habitat for sensitive species. In addition, climate change imposes a high degree of uncertainty on future forest productivity, sustainability of timber harvest, wildfire risk, and species habitat. We evaluated the long-term, landscape-scale trade-offs …

Regulation Of Sterol Biosynthesis In The Human Fungal Pathogen Aspergillus Fumigatus: Opportunities For Therapeutic Development, Sourabh Dhingra, Robert A. Cramer

Dartmouth Scholarship

Sterols are a major component of eukaryotic cell membranes. For human fungal infections caused by the filamentous fungus Aspergillus fumigatus, antifungal drugs that target sterol biosynthesis and/or function remain the standard of care. Yet, an understanding of A. fumigatus sterol biosynthesis regulatory mechanisms remains an under developed therapeutic target. The critical role of sterol biosynthesis regulation and its interactions with clinically relevant azole drugs is highlighted by the basic helix loop helix (bHLH) class of transcription factors known as Sterol Regulatory Element Binding Proteins (SREBPs). SREBPs regulate transcription of key ergosterol biosynthesis genes in fungi including A. fumigatus. …

Explosive Weapon Effects, Gichd

Global CWD Repository

Motivated by its strategic goal to improve human security and equipped with subject expertise in explosive hazards, the GICHD launched a research project to characterise explosive weapons. The GICHD perceives the debate on explosive weapons in populated areas (EWIPA) as an important humanitarian issue. The aim of this research into explosive weapons characteristics and their immediate, destructive effects on humans and structures, is to help inform the ongoing discussions on EWIPA, intended to reduce harm to civilians. The intention of the research is not to discuss the moral, political or legal implications of using explosive weapon systems in populated areas, …

The Effect Of Time Of Day Of Chronic Exercise On Neural Response To Visual Food Cues, Jessica Taylor Davies

Theses and Dissertations

This study examined the effect of an 8-week, progressive exercise intervention on neural responses, specifically N2 amplitude as a measure of inhibitory control, to pictures of food. Healthy women ages 18-44 years were randomized to a morning (AM) exercise group or evening (PM) exercise group. The AM group did moderate-to-vigorous intensity exercise on 4 days per week between 6:30 and 9:30 a.m. while the PM group had the identical volume of exercise between 6:30 and 9:30 p.m. Neural responses, eating behaviors, cardiovascular fitness outcomes, and body weight/composition were measured at baseline and after the 8-week intervention. The N2 amplitude in …

Frequency Response Reduced Order Model Of Primary Resonance Of Electrostatically Actuated Mems Circular Plate Resonators, Dumitru I. Caruntu, Reynaldo Oyervides

Mechanical Engineering Faculty Publications

This paper deals with the amplitude-frequency response of soft AC electrostatically actuated MEMS clamped circular plates. Alternating Current (AC) frequency is near half natural frequency of the plate. This results in primary resonance of the system. Two methods are used and compared, namely the Method of Multiple Scales (MMS), and Reduced Order Model (ROM). Both methods are in excellent agreement for amplitudes less than 0.4 of the gap. For amplitudes between 0.4 and 1 of the gap only seven terms ROM accurately predicts the behavior of the system. The effects of the voltage and damping parameters on the frequency response …

Multiscale Mutation Clustering Algorithm Identifies Pan-Cancer Mutational Clusters Associated With Pathway-Level Changes In Gene Expression., William Poole, Kalle Leinonen, Ilya Shmulevich, Theo A Knijnenburg, Brady Bernard

Articles, Abstracts, and Reports

Cancer researchers have long recognized that somatic mutations are not uniformly distributed within genes. However, most approaches for identifying cancer mutations focus on either the entire-gene or single amino-acid level. We have bridged these two methodologies with a multiscale mutation clustering algorithm that identifies variable length mutation clusters in cancer genes. We ran our algorithm on 539 genes using the combined mutation data in 23 cancer types from The Cancer Genome Atlas (TCGA) and identified 1295 mutation clusters. The resulting mutation clusters cover a wide range of scales and often overlap with many kinds of protein features including structured domains, …

Complexity's Shadow: American Indian Property, Sovereignty, And The Future, Jessica A. Shoemaker

Michigan Law Review

This Article offers a new perspective on the challenges of the modern American Indian land tenure system. While some property theorists have renewed focus on isolated aspects of Indian land tenure, including the historic inequities of colonial takings of Indian lands, this Article argues that the complexity of today’s federally imposed reservation property system does much of the same colonizing work that historic Indian land policies—from allotment to removal to termination—did overtly. But now, these inequities are largely overshadowed by the daunting complexity of the whole land tenure structure. This Article introduces a new taxonomy of complexity in American Indian …

Center Pivot Irrigation Handbook (Ec3017), Derrel Martin, William Kranz, Tyler Smith, Suat Irmak, Charles Burr, Ron Yoder

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Center pivot irrigation has been the most rapidly expanding form of irrigation in the Central Great Plains and across the United States. The amount of land irrigated with sprinkler, gravity and drip or trickle systems was determined for all states in the USA in the Farm and Ranch Irrigation Survey1 by the USDA in 2012. Results of the survey for the Great Plains States shows that approximately 85% of the land in Nebraska is irrigated with center pivots and that very little land was irrigated with drip systems in 2012 (Figure 1). The percentage of land irrigated with sprinklers in …

A Model Of The Use Of Evolutionary Trees (Muet) To Inform K-14 Biology Education, Yi Kong, Ankita Thawani, Trevor R. Anderson, Nancy Pelaez

PIBERG Publications

Evolutionary trees are powerful tools used in modern biological research, and also commonly used in textbooks and classroom instruction. Studies have shown that K-14 students have difficulties interpreting evolutionary trees. To improve student learning about this topic, it is essential to teach them how to understand and use trees like professional biologists. Unfortunately, few currently used teaching frameworks for evolution instruction are designed for this purpose. In this study we developed the Model of the Use of Evolutionary Trees (MUET), a conceptual model that characterizes how evolutionary trees were used by professional biologists as represented in their research publications. The …

Structural And Biochemical Characterization Of Cinnamoyl-Coa Reductases, Steven A. Sattler, Alexander M. Walker, Wilfred Vermerris, Scott E. Sattler, Chulhee Kang

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Cinnamoyl-coenzyme A reductase (CCR) catalyzes the reduction of hydroxycinnamoyl-coenzyme A (CoA) esters using NADPH to produce hydroxycinnamyl aldehyde precursors in lignin synthesis. The catalytic mechanism and substrate specificity of cinnamoyl-CoA reductases from sorghum (Sorghum bicolor), a strategic plant for bioenergy production, were deduced from crystal structures, site-directed mutagenesis, and kinetic and thermodynamic analyses. Although SbCCR1 displayed higher affinity for caffeoyl-CoA or p-coumaroyl-CoA than for feruloyl-CoA, the enzyme showed significantly higher activity for the latter substrate. Through molecular docking and comparisons between the crystal structures of the Vitis vinifera dihydroflavonol reductase and SbCCR1, residues threonine-154 and tyrosine-310 were pinpointed …

A Novel Tantalum-Containing Bioglass. Part Ii. Development Of A Bioadhesive For Sternal Fixation And Repair, Adel Mf Alhalawani, Cina Mehrvar, Wendy Stone, Stephen D. Waldman, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

With over a million median sternotomy surgeries performed worldwide every year, sternal wound complications have posed a serious risk to the affected patients. A rigid therapeutic sternal fixation device has therefore become a necessity. In this work, the incorporation of up to 0.5 mol% of tantalum pentoxide (Ta₂O₅), in exchange for zinc oxide (ZnO), into the SiO₂-ZnO-CaO-SrO-P₂O₅ glass system is presented. The effect of Ta incorporation on the physical, chemical and biological properties of the glass polyalkenoate cements (GPCs) prepared from them have been presented in this manuscript. The data obtained …

Feticide And Us Law, Gerard V. Bradley

Journal Articles

That abortion kills someone with a right-to-life has become easier to see since Roe v. Wade. Progress in scientific research and medical practice has made both birth and viability unrealistic criteria for demarcating between human life, which demands moral respect, and merely “potential life” which does not have moral or legal equivalency with maternal interest. The Eighth Circuit recently criticized the use of viability as a litmus test because it “tied a state’s interest in unborn children to developments in obstetrics, not to developments in the unborn.” The near-ubiquity of sonograms has probably done more than intellectual arguments to …

Large-Scale Behavior-Change Initiative For Infant And Young Child Feeding Advanced Language And Motor Development In A Cluster-Randomized Program Evaluation In Bangladesh, Edward A. Frongillo Jr., Phuong H. Nguyen, Kuntal K. Saha, Tina Sanghvi, Kaosar Afsana, Raisul Haque, Jean Baker, Marie T. Ruel, Rahul Rawat, Purnima Menon

Faculty Publications

Background: Promoting adequate nutrition through interventions to improve infant and young child feeding (IYCF) has the potential to contribute to child development.

Objective: We examined whether an intensive intervention package that was aimed at improving IYCF at scale through the Alive & Thrive initiative in Bangladesh also advanced language and gross motor development, and whether advancements in language and gross motor development were explained through improved complementary feeding.

Methods: A cluster-randomized design compared 2 intervention packages: intensive interpersonal counseling on IYCF, mass media campaign, and community mobilization (intensive) compared with usual nutrition counseling and mass media campaign (nonintensive). Twenty subdistricts …

5'-Terminal Nucleotide Variations In Human Cytoplasmic Trnahisgug And Its 5'-Halves., Megumi Shigematsu, Yohei Kirino

Computational Medicine Center Faculty Papers

Transfer RNAs (tRNAs) are fundamental adapter components of translational machinery. tRNAs can further serve as a source of tRNA-derived noncoding RNAs that play important roles in various biological processes beyond translation. Among all species of tRNAs, tRNA(HisGUG) has been known to uniquely contain an additional guanosine residue at the -1 position (G-1) of its 5'-end. To analyze this -1 nucleotide in detail, we developed a TaqMan qRT-PCR method that can distinctively quantify human mature cytoplasmic tRNA(HisGUG) containing G-1, U-1, A-1, or C-1 or lacking the -1 nucleotide (starting from G1). Application of this method to the mature tRNA fraction of …

Identity And Its Political Manipulation In Syria, Nada Yasser Sharkawy

Theses and Dissertations

This research takes a social constructivist approach in order to analyze how identity is used as a political tool, leading to the current civil war in Syria. Identity plays a great role in the political scene in Syria ever since the French Mandate, in which the state was broken into an ethnofederal system. Subsequently the French employed a divide and conquer tactic in order to prevent the unity of Syria therefore making it easier to establish control. Later on, after multiple coups, Hafiz Al-Assad rose to power along with a select group of trusted individuals from his family, tribe, and …

The Influence Of Disclosure History And Body Diagrams On Children's Reports Of Inappropriate Touching: Evidence From A New Analog Paradigm, Jason Dickinson, Debra Ann Poole

Department of Psychology Faculty Scholarship and Creative Works

We tested a new paradigm for child eyewitness research that incorporates children's disclosure histories into analog study designs. Mr. Science - Germ Detective creates meaningful touching experiences and varied patterns of preinterview disclosures by convincing children that touching in the laboratory is potentially contaminating (germy). Children (N = 287, 4 to 8 years) heard that Mr. Science could no longer touch children's skin and then participated in an educational program involving 2 attempted touches. A week later, their disclosure histories were determined by a phone call that occurred a day before a forensic-style interview in the laboratory. This interview was …
