Percutaneous Tracheostomy; As It Stands Today, Devaraja K

Manipal Journal of Medical Sciences

Conventionally, tracheostomy includes surgical creation of tracheo-cutaneous communication. It is done either to bypass the upper airway obstruction or to facilitate optimal mechanical ventilation and early weaning off the ventilator support in neurologically unstable patients. For many years now, percutaneous tracheostomy has been proposed as an alternative to open surgical tracheostomy in ventilator-dependent patients. This review briefly narrates the principles and procedure of percutaneous tracheostomy. In addition, the article sheds light on a few critical problems that one could encounter during the process and discusses countermeasures to overcome those difficulties. Finally, the role of intra-procedure bronchoscopy or ultrasonography and of …

Post-Coarctectomy Syndrome And The Use Of Gabapentin For Gi Ileus: A Case Report, Vinay Krupadev

Manipal Journal of Medical Sciences

Post-coarctectomy syndrome is a complication of aortic arch repair that occurs due to a sudden increase in reperfusion of the body’s vasculature following surgery. One complication related to postcoarctectomy syndrome is ileus which can prolong a patient’s ICU stay and delay discharge home. While traditionally supportive care has been used to resolve this condition, this case highlights the use of gabapentin as a relatively novel treatment for post-coarctectomy syndrome gastrointestinal ileus.

Getting It Right! Improving Kenya’S Human Capital By Reducing Stunting—A Household Account, Timothy Abuya, Wangari Ng'ang'a

Reproductive Health

In the last two decades, Kenya has attained middle-income status and established a diverse and private-sector-driven economy. On several socio-economic indicators, such as education, gender equality, and democracy, Kenya scores much higher than its peers. More than two-thirds of Kenyans are under 35 years of age, thus the country’s development hinges on the quality of its youth—their levels of education and skills, their values and attitudes, and the quality of their health and productivity. While Kenya’s investments in the development of its human capital positions the country well to sustain accelerated growth, the trajectory is threatened by high rates of …

School of Law, Humanities and Social Sciences

Animism and Interconnectivity is an ethnographic study of Batek Dè’ and Manya’ religion on the periphery of the Malaysian rainforest. In the twenty-first century, the lives of these two small-scale groups of former hunter-gatherers take place on the interconnected frontier between forest and the outside world, a nexus of different ideas, peoples and objects of diverse origins. Through an examination of specific events occurring in particular places on the forest periphery, the thesis highlights changes and continuities in shamanistic practices, myths, cosmologies and relations with other-than-human beings in the transformed physical and social landscape. Each chapter presents ethnographic vignettes and …

Electroshock Treatment Dependent Microstructural Evolution And Mechanical Properties Of Near-Β Titanium Alloy Manufactured By Directed Energy Deposition, Haojie Guo, Pu Liu, Xunpeng Qin, Yanli Song, Dongsheng Qian, Lechun Xie, Liqiang Wang, Lai-Chang Zhang, Lin Hua

Research outputs 2014 to 2021

Effects of electroshock treatment (EST) on the microstructural evolution and mechanical properties of near-β titanium alloy (Ti-55531) formed by directed energy deposition (DED) was studied in this work. With the increase in EST time, the average hardness of specimen decreased from 426 HV to 316 HV, and the fracture strain increased significantly, which was attributed to the uniform dispersion of α phase along grain boundaries and inside the β grains. After EST, the texture intensity decreased in terms of the orientation distribution function (ODF), which was ascribed to the redistribution of α phase. Moreover, more atomic vacancies and lattice distortion …

Modifying The Aspect Survey To Support The Validity Of Student Perception Data From Different Active Learning Environments, Nicole Naibert, Erin E. Shortlidge, Jack Barbera

Chemistry Faculty Publications and Presentations

Measuring students’ perceptions of active learning activities may provide valuable insight into their engagement and subsequent performance outcomes. A recently published measure, the Assessing Student Engagement in Class Tool (ASPECT), was developed to assess student perceptions of various active learning environments. As such, we sought to use this measure in our courses to assess the students’ perceptions of different active learning environments. Initial results analyzed with confirmatory factor analysis (CFA) indicated that the ASPECT did not function as expected in our active learning environments. Therefore, before administration within an introductory biology course that incorporated two types of active learning strategies, …

Inequalities In Heterosexual Sex And How We Can Become Equals, Sophie Bierly

Undergraduate Honors Theses

Sexual inequality is well researched in the academic sphere but is absent from the political realm. Previous research has identified that sex is defined for men’s pleasure, that women suffer from an orgasm gap, and that male domination is standard in heterosexual sex. Due to the private nature of sex, sexual inequality is untouched as a personal problem rather than deconstructed as a political injustice. However, the universality of sexual inequality in heterosexual relationships demonstrates that these overlooked personal problems are rooted in widespread cultural misogyny. Sex is one of the primary ways in which we perform gendered socialization, due …

Age-Dependent Search Behavior In The Colorado Checkered Whiptail (Aspidoscelis Neotesselatus), Carina Kusaka, Kaera Utsumi, Catherine Staley, Rachael Pedersen, Julia Valdivia, Elizabeth Liu, Hannah Caracalas, Hannah Reynolds, Maria A. Eifler, Douglas A. Eifler

Western North American Naturalist

We compared movement and space use patterns of foraging adult and juvenile Colorado checkered whiptails (Aspidoscelis neotesselatus) in pinyon pine–juniper woodland. Through focal observations, we characterized (1) movement paths as a series of step lengths and turn angles at 30-s intervals, and (2) habitat use reflected by the proportion of time spent in different vegetation types and in the open. Adults and juveniles differed in both movement and habitat use. Adults spent more time in the open and in association with mountain mahogany (Cercocarpus montanus), while juveniles were more frequently found in association with dead wood, …

Nesting Biology And Offspring Development Of The Cavity-Nesting Solitary Wasp Isodontia Elegans (F. Smith) From Trap-Nests In Oregon, Ronald C. Spendal, Kevin M. O'Neill, Casey M. Delphia

Western North American Naturalist

We studied the nesting biology and developmental schedules of the cavity-nesting solitary wasp Isodontia elegans in Oregon, USA. Trap-nests contained 1–15 brood cells each, separated by partitions, which adult females made with grass fragments. Before leaving nests to hunt, females made loose, temporary closures of longer fragments of dried grass and, upon returning, briefly deposited prey just inside the nest entrance before transferring them to a cell. Cells were provisioned with katydids (Meconema thalassinum, an invasive species in North America) and tree crickets (Oecanthus fultoni), the latter predominating as summers progressed. The inner cells of nests, …

Whooping Crane (Grus Americana) Family Consumes A Diversity Of Aquatic Vertebrates During Fall Migration Stopover At The Platte River, Nebraska, Andrew J. Caven, Keith D. Koupal, David M. Baasch, Emma M. Brinley Buckley, Jenna Malzahn, Michael L. Forsberg, Mariah Lundgren

Western North American Naturalist

The Aransas-Wood Buffalo population of Whooping Cranes (Grus americana) migrates approximately 4000 km through the central Great Plains biannually, between their breeding and wintering grounds. Whooping Cranes depend on stopover sites to provide secure resting locations and the caloric resources necessary to complete their migration, such as the USFWS-designated critical habitat area in the Central Platte River Valley (CPRV) of Nebraska. This area includes braided river habitat characterized by low-elevation and submerged sandbars, which provide important roosting and foraging opportunities for migrating Whooping Cranes. We used long-range photography, videography, and behavioral scan sampling to document forage items consumed …

Ultrafast Spectroscopy Of Air Lasing In Filaments, Brian Robert Kamer

Optical Science and Engineering ETDs

Filamentation in air is a phenomenon that has been extensively investigated for the last two decades. At sufficiently high intensity, even air is a nonlinear medium. These intensities are reached with ultrashort pulses (50 to 100 fs) of more than 1 J energy, which self-focus in air, reach ionizing intensities of oxygen and nitrogen, creating a plasma that defocuses the beam. The air filament is a self-induced waveguide resulting from a balance of focusing and defocusing. In this work new techniques were developed to visualize and analyze this phenomenon through its emission, in particu- lar the UV emission of the …

Spatial Variability In Streambed Microbial Community Structure Across Two Watersheds, Philips Akinwole, Jinjun Kan, Louis A. Kaplan, Robert H. Findlay

Biology Faculty publications

Both spatial and temporal variability are key attributes of sedimentary microbial communities, and while spatial effects on beta-diversity appear to dominate at larger distances, the character of spatial variability at finer scales remains poorly understood, especially for headwater stream communities. We investigated patterns of microbial community structure (MCS) in biofilms attached to streambed sediments from two watersheds across spatial scales spanning ,1 m within a single stream to several hundred kilometers between watersheds. Analyses of phospholipid fatty acid (PLFA) profiles indicated that the variations in MCS were driven by increases in the relative abundance of microeukaryotic photoautotrophs and their contribution …

Lived Experiences Of New Nurses With Lateral Violence And Their Decision To Remain In The Nursing Profession, Lorraine Ann Hover

Dissertations

The issue of lateral violence, or nurse-on-nurse violence, is a major factor in why new nurses leave the nursing profession within the first two years of professional practice. There is considerable research into mitigating factors, why nurses leave, and programs to address lateral violence, however, little to no research has been conducted on why nurses choose to remain in the profession despite their experiences. This lack of research necessitates the need for further study into the lived experiences of new nurses with lateral violence and their decision to remain in the profession. This qualitative descriptive phenomenological study helps to address …

Mixture Design Response Surface Methodology Analysis Of Seven Natural Bioactive Compounds To Treat Prostate Cancer, Ian Geddes Berlin

Theses and Dissertations

Natural bioactive compounds have drawn the interest of many researchers worldwide in their effort to find novel treatments, including prostate cancer (PC) treatment which is estimated to be 13.1% of all new cancer cases in the U.S. in 2021. Many of these bioactive compounds have been identified from treatments in traditional Chinese medicine (TCM), that often have multiple bioactive compounds present. However, in vitro studies frequently focus on the compounds in isolation, or in simple combinations of two compounds. We used mixture design response surface methodology (MDRSM) to assess changes in PC cell viability after 48 hours of treatment to …

Calculating Common Vulnerability Scoring System’S Environmental Metrics Using Context-Aware Network Graphs, Christopher Thomas Enoch

Theses

Software vulnerabilities have significant costs associated with them. To aid in the prioritization of vulnerabilities, analysts often utilize Common Vulnerability Scoring System’s Base severity scores. However, the Base scores provided from the National Vulnerability Database are subjective and may incorrectly convey the severity of the vulnerability in an organization's network. This thesis proposes a method to statically analyze context-aware network graphs to increase accuracy of CVSS severity scores. Through experimentation of the proposed methodology, it is determined that context-aware network graphs can capture the required metrics to generate modified severity scores. The proposed approach has some accuracy to it, but …

Analyzing The Arguments And Opinions Surrounding Space Privatization, Henry Yaeger

Theses

As space exploration technology advances and more private actors engage in independent space activities, national governments and international organizations need to reform and modernize their approach to regulating private space activities in order to better capture and distribute the benefits of those activities. This paper examines several disparate suggestions and ideas found in 38 articles ranging from current space policy literate to international treaties in order to generate four possible policy approaches to private space activities: the Status Quo, Self-Regulation, New International Treaties and Expanded Public-Private Partnership models. It then compares and contrasts these four alternatives to determine which can …
