The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck

Human–Wildlife Interactions

Bird interactions with electric power lines can cause faults (e.g., disruption of electrical service). Faults on 500kV transmission lines in Montana, USA, which are integral to the Northwest USA power grid, became concerning during winter 2016–2017. In 2017 we found insulators contaminated with bird droppings and discovered a large nocturnal roost of common ravens (Corvus corax). To assess the potential magnitude of the impact of raven roosts on electric power transmission, we summarized fault data obtained from the Energy Management System and raven abundance data obtained from the Christmas Bird Count in central Montana from 2005 to 2020. …

Imagining The Internal Reproductive Environment: Function And Evolution Of The Drosophila Melanogaster Female Reproductive Tract, Caitlin Elizabeth Mcdonough-Goldstein

Dissertations - ALL

Sexual reproduction involves complex coordination, and potentially competition, among the reproductive cells, fluids, and structures of all individuals involved. For internally fertilizing species, these interactions occur within the body of one sex, predominantly the female, or ovary-associated, reproductive tract. Thus, characterizing the dynamics of the female reproductive tract is critical to understanding the interactions that mediate reproductive success. Although there has been increasing movement toward revealing the active role of the female reproductive tract in shaping and influencing reproductive outcomes, our knowledge of this environment remains limited as a result of both historical biases and technical constraints. My dissertation advances …

Control Of Blood Volume Following Hypovolemic Challenge In Vertebrates: Transcapillary Versus Lymphatic Mechanisms., Stanley S. Hillman, Robert C. Drewes, Michael S. Hedrick

Biology Faculty Publications and Presentations

Anurans have an exceptional capacity for maintaining vascular volume compared with other groups of vertebrates. They can mobilize interstitial fluids via lymphatic return at rates that are ten-fold higher than mammals. This extraordinary capacity is the result of coordination of specialized skeletal muscles and pulmonary ventilation that vary volume and pressure of subcutaneous lymph sacs, thus moving lymph to dorsally located lymph hearts that return lymph to the vascular space. Variation in the capacity to mobilize lymph within anurans varies with the degree of terrestriality, development of skeletal muscles, lung volume and lung compliance, and lymph heart pressure development. This …

Effect Of Surfactant Addition On The Dispersion And Antioxidant Performance Of Pyrogallol In Biodiesel, Silvya Yusri, Mohammad Nasikin, Hery Sutanto

Makara Journal of Science

Biodiesel is one of the most feasible energy sources that can be used as a replacement for fossil fuel. Biodiesel has several advantages over conventional fuels because of its availability, renewability, and high combustion efficiency. However, biodiesel that contains unsaturated fatty acid methyl esters is prone to oxidation during the blending process and storage period. The complete oxidation reaction of biodiesel produces insoluble gums that could potentially plug the fuel engines. This reaction has become the main barrier for biodiesel to compete with other biofuels. Among several methods, the addition of antioxidants is the most cost-effective method to prevent the …

Lemongrass (Cymbopogon Citratus) Ethanolic Extract Exhibited Activities That Inhibit -Glucosidase Enzymes And Postprandial Blood Glucose Elevation, Maria Dewi Puspitasari Tirtaningtyas Gunawan Puteri, Felicia Melissa Tjiptadi, Phebe Hendra, Filiana Santoso, Zalinar Udin, Nina Artanti, Florence Ignatia Florence Ignatia

Makara Journal of Science

Lemongrass is a common ingredient in Indonesian traditional herbal medicine that potently inhibits carbohydrate hydrolysis. In this study, the in vitro α-glucosidase inhibitory (AGI) activity of lemongrass was compared with its in vivo activity to retard postprandial blood glucose elevation, and the bioactive compounds responsible for these activities were observed. Both water and ethanolic extracts of lemongrass (WLG and ELG, respectively) were tested in vitro for its inhibition of the sucrose and maltose hydrolyzing activities of rat intestinal glucosidase. ELG was observed to exert higher inhibitory activities (Sucrase IC₅₀ = 8.74 mg/mL; Maltase IC₅₀ = 18.93 mg/mL) than …

Computational Analysis Of Chromophore Tripeptides Followingfusion Of Enhanced Green Fluorescent Protein And Cell-Penetrating Peptides, Silvia Tri Widyaningtyas, Ekawati Betty Pratiwi, Budiman Bela

Makara Journal of Science

Cell-penetrating peptides (CPPs) are small peptides that can transfer other materials into a cellular compartment. In this research, we studied the effect of fusion of new CPPs to the N-terminal of enhanced Green Fluorescent Protein eGFP on the ability of the latter to fluoresce. Results showed that the recombinant protein CPPs-eGFP could be successfully expressed in Escherichia coli. In contrast to E. coli expressing wild-type eGFP, which could fluoresce under ultraviolet (UV) or visible light, E. coli expressing CPPs-eGFP lost their ability to fluoresce. PyMol, a molecular visualization system, revealed that fusion of the new CPPs to the N-terminal …

Organic Production Of Livestock And Livestock Products In Nebraska, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

USDA “Certified Organic” is a form of production that has received considerable public attention in the last 10 years, particularly among small, beginning and/or minority farmers. Spiking retail prices for red meat and poultry have seemingly accelerated consumer’s interest in organic locally produced products. Consumers demonstrate their desire for these products by paying premiums when purchasing meat products. Producers receive premiums by either directly marketing live animals to consumers that are custom harvested or marketing animals to meat wholesalers. The primary difference is the way premiums are captured. Producers doing custom harvesting capture the full premium whereas producers …

Quantifying Anticancer Drug Doxorubicin Binding To Dna Using Optical Tweezers, Zachary Ells

Honors Program Theses and Projects

Doxorubicin is a successful anticancer drug approved for use in the 1970s and is considered to be one of the most effective cancer treatment methods today. Although Doxorubicin has positive survival statistics it has very negative side effects in many cases. Bleeding from the soles of the palms and feet, along with excruciating pain is often exhibited through the administration of this drug. Based on the preliminary findings utilizing optical tweezers we anticipate that this study will provide critical information about the drug binding mechanism. Single molecule biophysics techniques have provided useful insight into the DNA-binding mechanisms of small molecules. …

Influence Of Testosterone On Male-Male Competition In The Red-Sided Garter Snake, Thamnophis Sirtalis Parietalis, Isabella M. G. Bukovich

Senior Honors Projects, 2020-current

Female mimicry in the red-sided garter snake, Thamnophis sirtalis parietalis, is described in several well-studied evolutionary advantages, but an aspect that remains elusive is how reproductive traits are linked to the 3-fold higher circulating androgens in males with this phenotype. In this study, we implanted male garter snakes (n=15 per group) with either a blank implant (SHAM; control) or a T implant, the latter simulating the female mimic phenotype. Following simulated low-temperature dormancy, males were scored for courtship intensity over three days of behavioral trials with females housed in the same facility. Males were sacrificed, and sperm were collected …

Widaman, Bettina Hieronimus, Marinelle V. Nunez, Vivien Lee, Yanet Benyam, Andrew A. Bremer, Valentina Medici, Peter J. Havel, Kimber L. Stanhope, Nancy L. Keim

Faculty Research, Scholarly, and Creative Activity

Sugar-sweetened beverage (sugar-SB) consumption is associated with body weight gain. We investigated whether the changes of (Δ) circulating leptin contribute to weight gain and ad libitum food intake in young adults consuming sugar-SB for two weeks. In a parallel, double-blinded, intervention study, participants (n = 131; BMI 18–35 kg/m2; 18–40 years) consumed three beverages/day containing aspartame or 25% energy requirement as glucose, fructose, high fructose corn syrup (HFCS) or sucrose (n = 23–28/group). Body weight, ad libitum food intake and 24-h leptin area under the curve (AUC) were assessed at Week 0 and at the end of Week …

Mission-Centered Collaborative Bridges To Increase Stem Motivations, Colleen Duffy

Journal of Vincentian Social Action

Many school administrators are enthusiastic about implementing new educational initiatives but have their plans thwarted because they are faced with the reality of insufficient resources. This can greatly limit the expansion of K-12 educational programs and deprive students of valuable learning opportunities. Additionally, teacher preparation programs are required to meet state mandates such as providing field experiences for preservice teachers that promote the authentic application of knowledge in PK-12 classrooms, but regional competition for placement opportunities create tremendous obstacles for higher education faculty. This essay describes the creation and implementation of a mission-centered mutually beneficial K-12 and intercollegiate partnership that …

Building Teacher Empathy And Culturally Responsive Practice Through Professional Development And Self-Reflection, Barbara S. Rieckhoff, Melissa Ockerman, Amira Proweller, James Wolfinger

Journal of Vincentian Social Action

Today’s teachers face growing demands and mandates to support every aspect of a student’s academic success, with additional expectations to support students’ social and emotional needs both inside and outside of the classroom. In the face of increasing student cultural, racial and linguistic diversity, the teaching pool remains relatively homogeneous, consisting largely of white, European-American educators. This disconnect between the lived experiences of teachers and their students makes it difficult for teachers to value and connect to a diverse student body. This qualitative study explores how a collaborative multi-tiered critical professional development model between a non-for-profit organization and a University, …

Symbolic Boundaries And The Clinical Preparation Of Teacher Candidates, Bilge Cerezci, Donald Mcclure

Journal of Vincentian Social Action

The purpose of this essay is to make sense of the two divides in the clinical preparation of teacher candidates: (1) between professional knowledge and skilled practice, and (2) between university-based courses and school-based field experiences. This essay extends the work of Lamont and Molnár (2002) to conceptualize symbolic boundaries related to these two divides. Within this framework, a review of the research highlights three main implications. First, teacher education programs need to design teaching and learning experiences that allow teacher candidates to use the professional knowledge they have gained through their university courses across multiple educational settings. Second, such …

Improving Co-Teachers Relationships, Asher Samuel

Journal of Vincentian Social Action

Co-teaching is an instructional strategy wherein two teachers, a general education teacher and a special education teacher, share instructional responsibilities in a general education class that includes students with disabilities (SWDs) (Friend, 2010). An important component of co-teaching is the relationship between the teachers (Kohler-Evans, 2006), which has been described as a professional marriage (Friend, 2010). However, there is limited information on factors influencing the relationship. This study investigated if teaching experience affects co-teachers’ perception of teamwork. Participants included special and general education co-teachers from eight public school districts in New York City. Co-teachers from grades K-12 completed the Tuckman …

The Impact Of Universally Accelerating Eighth Grade Mathematics Students On Participation And Achievement, Patrick Walsh

Journal of Vincentian Social Action

In New York State students are traditionally scheduled to take Algebra I in their first year of high school mathematics. However, in many schools, the “top” students in a cohort have access to this course in eighth grade, tracking these high-achieving students ahead of their lower-achieving peers. In response, some schools have adopted the policy of “Algebra for all” in eighth grade – called universal acceleration. While this policy ensures equal access to a challenging curriculum for all students, regardless of race, socioeconomic status, and prior achievement, there is a concern that not all students are developmentally ready to take …
