Opportunistic Validation Of Sulfur Dioxide In The Sarychev Peak Volcanic Eruption Cloud, S. Carn, T. M. Lopez

Michigan Tech Publications, Part 1

We report attempted validation of Ozone Monitoring Instrument (OMI) sulfur dioxide (SO 2) retrievals in the stratospheric volcanic cloud from Sarychev Peak (Kurile Islands) in June 2009, through opportunistic deployment of a ground-based ultraviolet (UV) spectrometer (FLYSPEC) as the volcanic cloud drifted over central Alaska. The volcanic cloud altitude (∼12-14 km) was constrained using coincident CALIPSO lidar observations. By invoking some assumptions about the spatial distribution of SO 2, we derive averages of FLYSPEC vertical SO 2 columns for comparison with OMI SO 2 measurements. Despite limited data, we find minimum OMI-FLYSPEC differences within measurement uncertainties, which support the validity …

Spectral Geometry Image: Image Based 3d Models For Digital Broadcasting Applications, Boon Seng Chew, Lap Pui Chau, Ying He, Dayong Wang, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

The use of 3D models for progressive transmission and broadcasting applications is an interesting challenge due to the nature and complexity of such content. In this paper, a new image format for the representation of 3D progressive model is proposed. The powerful spectral analysis is combined with the state of art Geometry Image(GI) to encode static 3D models into spectral geometry images(SGI) for robust 3D shape representation. Based on the 3D model's surface characteristics, SGI separated the geometrical image into low and high frequency layers to achieve effective Level of Details(LOD) modeling. For SGI, the connectivity data of the model …

An Efficient Adaptive Vortex Particle Method For Real-Time Smoke Simulation, Shengfeng He, Hon-Cheng Wong, Un-Hong Wong

Research Collection School Of Computing and Information Systems

Smoke simulation is one of the interesting topics in computer animation and it usually involves turbulence generation. Efficient generation of realistic turbulent flows becomes one of the challenges in smoke simulation. Vortex particle method, which is a hybrid method that combines grid-based and particle-based approaches, is often used for generating turbulent details. However, it may cause irrational artifacts due to its initial condition and vorticity forcing approach used. In this paper, a new vorticity forcing approach based on the spatial adaptive vorticity confinement is proposed to address this problem. In this approach, the spatial adaptive vorticity confinement force varies with …

Evolutionary Theory Of Mate Selection And Partners Of Trans People: A Qualitative Study Using Interpretative Phenomenological Analysis, Amanda Forde

The Qualitative Report

Despite much research into mate selection, non-heterosexual populations are often only included for comparison purposes, while trans people and their partners are overlooked. This study attempts to address this using qualitative methodology to explore the mate selection of the partners of trans people. Six participants were recruited from online communities and interviewed via instant messaging, the results were then analysed using Interpretative Phenomenological Analysis. The author organised the results into four themes. Theme one: Identities/relationships which defy categorisation, Theme Two: Attractive traits and mate selection, Theme Three: Impact of past romantic relationships, other relationships and life changes and Theme Four: …

A Dynamic Inventory Optimization Method Applied To Printer Fleet Management, Surya Saripalli

Theses

Current optimization methods for inventory management of toner cartridges for printer fleets typically focus on aggregate cartridge demand. However, with the development of printer technology, toner consumption algorithms are being developed which can accurately quantify the amount of toner that has been consumed over time, based on print job characteristics. This research introduces a dynamic inventory optimization approach for a fleet of printers over a rolling time horizon. Given, the consumption algorithm for the printer system, the cumulative toner consumed per cartridge per printer can be tracked. A forecasting method is developed which utilizes this toner consumption data for individual …

Dynamic Alteration Of Adiponectin/Adiponectin Receptor Expression And Its Impact On Myocardial Ischemia/Reperfusion In Type 1 Diabetic Mice., Yanzhuo Ma, Yi Liu, Shaowei Liu, Yan Qu, Rutao Wang, Chenhai Xia, Haifeng Pei, Kun Lian, Tao Yin, Xiaoyan Lu, Lu Sun, Lu Yang, Yanjie Cao, Wayne Bond Lau, Erhe Gao, Haichang Wang, Ling Tao

Department of Emergency Medicine Faculty Papers

The present study determined the dynamic change of adiponectin (APN, a cardioprotective adipokine), its receptor expression, and their impact upon myocardial ischemia/reperfusion (MI/R) injury during type 1 diabetes mellitus (T1DM) progression, and involved underlying mechanisms. Diabetic state was induced in mice via multiple intraperitoneal injections of low-dose streptozotocin. The dynamic change of plasma APN concentration and cardiac APN receptor-1 and -2 (AdipoR1/2) expression were assessed immediately after diabetes onset (0 wk) and 1, 3, 5, and 7 wk thereafter. Indicators of MI/R injury (infarct size, apoptosis, and LDH release) were determined at 0, 1, and 7 wk of DM duration. …

Relationship Of Adipokines With Insulin Sensitivity In African Americans., Maria P Martinez Cantarin, Scott W Keith, Stephanie Deloach, Yonghong Huan, Bonita Falkner

Department of Medicine Faculty Papers

INTRODUCTION: Cytokines produced by adipose tissue, including adiponectin, have been associated with metabolic abnormalities. The purpose of this study was to examine the relationship of insulin sensitivity measured by euglycemic hyperinsulinemic insulin clamp with plasma adiponectin and other adipokines in young adult African Americans.

METHODS: Participants were healthy African Americans. Anthropometric measures, blood pressure, an oral glucose tolerance test and an euglycemic hyperinsulinemic insulin clamp were performed. Insulin sensitivity measurements were adjusted for percentage of fat mass. Plasma concentrations of adiponectin, plasminogen activator inhibitor-1 (PAI-1) and interleukin-6 (IL-6) were assayed on plasma from fasting blood samples. Pearson correlation coefficients and …

Sirolimus-Induced Pneumonitis Complicated By Pentamidine-Induced Phospholipidosis In A Renal Transplant Recipient: A Case Report., E J Filippone, J M Carson, R A Beckford, B C Jaffe, E Newman, B K Awsare, C Doria, J L Farber

Department of Medicine Faculty Papers

The proliferation signal inhibitors (PSIs)-sirolimus, everolimus, and temsirolimus-have been associated with a noninfectious pneumonitis characterized by lymphocytic alveolitis and bronciolitis obliterans with organizing pneumonia (BOOP). This condition usually occurs within the first year. Herein we presented a case of a deceased donor renal transplant with interstitial pneumonitis developing 6 years after a switch from tacrolimus to sirolimus due to chronic graft dysfunction. After the addition of intravenous pentamidine due to the suspicion of Pneumocystis pneumonia, there was marked clinical deterioration requiring intubation. Open lung biopsy revealed sirolimus-induced pulmonary toxicity (BOOP) with the additional finding of a drug-induced phospholipidosis (DIPL) that …

Using Skos To Express Faceted Classification On The Semantic Web, Theresa Putkey

Library Philosophy and Practice (e-journal)

This paper looks at Simple Knowledge Organization System (SKOS) to investigate how faceted classifications can be expressed in RDF and shared on the Semantic Web. This paper first restates a definition of faceted classification, shares a faceted taxonomy, restates the definition of the Semantic Web and RDF, then looks into the SKOS standard and the PoolParty software to build a faceted taxonomy in an SKOS compliant format. This paper then discusses the research approach.

Socially Induced Ovulation Synchrony And Its Effect On Seabird Population Dynamics, Shandelle M. Henson, J. M. Cushing, James L. Hayward

Faculty Publications

Spontaneous oscillator synchrony is a form of self-organization in which populations of interacting oscillators ultimately cycle together. This phenomenon occurs in a wide range of physical and biological systems. In rats and humans, oestrous/menstrual cycles synchronize through social stimulation with pheromones acting as synchronizing signals. In previous work, we showed that glaucous-winged gulls (Larus glaucescens) can lay eggs synchronously on an every-other-day schedule, and that synchrony increases with colony density. We posed a discrete-time mathematical model for reproduction during the breeding season based on the hypothesis that pre-ovulatory luteinizing hormone surges synchronize by means of visual, auditory and/or olfactory cues. …

Type Ii Toxoplasma Gondii Ku80 Knockout Strains Enable Functional Analysis Of Genes Required For Cyst Development And Latent Infection, Barbara A. Fox, Alejandra Falla, Leah M. Rommereim, Tadakimi Tomita

Dartmouth Scholarship

Type II Toxoplasma gondii KU80 knockouts (Δku80) deficient in nonhomologous end joining were developed to delete the dominant pathway mediating random integration of targeting episomes. Gene targeting frequency in the type II Δku80 Δhxgprt strain measured at the orotate (OPRT) and the uracil (UPRT) phosphoribosyltransferase loci was highly efficient. To assess the potential of the type II Δku80 Δhxgprt strain to examine gene function affecting cyst biology and latent stages of infection, we targeted the deletion of four parasite antigen genes (GRA4, GRA6, ROP7, and tgd057 …

Deletion Of Rb Accelerates Pancreatic Carcinogenesis By Oncogenic Kras And Impairs Senescence In Pre-Malignant Lesions, Catherine Carrière, A. Jesse Gore, Alixanna M. Norris, Jason R. Gunn, Alison Young, Daniel Longnecker, Murray Korc

Dartmouth Scholarship

Rb1 encodes a cell-cycle regulator that is functionally disrupted in most human cancers. Pancreatic ductal adenocarcinomas (PDACs) have a high frequency of mutations in KRAS and INK4A/CDKN2A that might allow cells to bypass the regulatory actions of retinoblastoma (RB). To determine the role of loss of RB function in PDAC progression, we investigated the effects of Rb disruption during pancreatic malignant transformation initiated by oncogenic Kras.We generated mice with pancreas-specific disruption of Rb, in the absence or presence of oncogenic Kras, to examine the role of RB in pancreatic carcinogenesis.

Protoporphyrin Ix Fluorescence Contrast In Invasive Glioblastomas Is Linearly Correlated With Gd Enhanced Magnetic Resonance Image Contrast But Has Higher Diagnostic Accuracy, Kimberley S. Samkoe, Summer L. Gibbs-Strauss, Harold H. Yang, S. Khan Hekmatyar, P. Jack Hoopes, Julia A. O'Hara, Risto A. Kauppinen, Brian W. Pogue

Dartmouth Scholarship

The sensitivity and specificity of in vivo magnetic resonance (MR) imaging is compared with production of protoporphyrin IX (PpIX), determined ex vivo, in a diffusely infiltrating glioma. A human glioma transfected with green fluorescent protein, displaying diffuse, infiltrative growth, was implanted intracranially in athymic nude mice. Image contrast from corresponding regions of interest (ROIs) in in vivo MR and ex vivo fluorescence images was quantified. It was found that all tumor groups had statistically significant PpIX fluorescence contrast and that PpIX contrast demonstrated the best predictive power for tumor presence. Contrast from gadolinium enhanced T1-weighted (T1W+Gd) and absolute T2 …

Step-Wise Loss Of Bacterial Flagellar Torsion Confers Progressive Phagocytic Evasion, Rustin R. Lovewell, Ryan M. Collins, Julie L. Acker, George A. O'Toole, Matthew J. Wargo, Brent Berwin, Craig R. Roy

Dartmouth Scholarship

Phagocytosis of bacteria by innate immune cells is a primary method of bacterial clearance during infection. However, the mechanisms by which the host cell recognizes bacteria and consequentially initiates phagocytosis are largely unclear. Previous studies of the bacterium Pseudomonas aeruginosa have indicated that bacterial flagella and flagellar motility play an important role in colonization of the host and, importantly, that loss of flagellar motility enables phagocytic evasion. Here we use molecular, cellular, and genetic methods to provide the first formal evidence that phagocytic cells recognize bacterial motility rather than flagella and initiate phagocytosis in response to this motility. We demonstrate …

The Impact Of Dynamic And Passive Standing On Bone Mineral Density And Appositional Growth In Immobilized Children, Megan Diane Damcott

Dissertations

The first discovery of the potential role that mechanical loading has on determining the strength of bone occurred in 1892. However, for almost a century after this discovery, the specific mechanisms influenced by mechanical loading remained locked in a mysterious 'black box'. Then in the 1960s, the 'black box' was opened and continued work has now unlocked the basic mechanisms involved in mechanical loading and whole-bone strength. This increased knowledge has spurred clinicians and researchers to investigate the impact of weight-bearing interventions on individuals with an increased risk of osteoporosis. The most common weight-bearing clinical intervention used in non-ambulant populations …

Development Of Guidelines For Using Bioextraction Technologies To Manage Nutrients In New Hampshire's Estuarine Waters, Raymond E. Grizzle

PREP Reports & Publications

There is growing literature on bioextraction approaches to managing nutrients in coastal waters, and it includes studies using a variety of species. Bivalve mollusks and macroalgae have received the most attention for several reasons, but perhaps foremost because of their aquaculture potential. A December 2009 workshop at the University of Connecticut, which included speakers from several countries, indicated overall that although bioextraction approaches hold substantial potential there are still many unanswered questions. The present review takes a “what we know/what we need to know” perspective, and focuses on aquaculture. For some taxa (e.g., eastern oyster), wild populations occur in New …

De-Placing Local At The Farmers' Market: Consumer Conceptions Of Local Foods, Damian C. Adams, Alison E. Adams

Journal of Rural Social Sciences

Demand for local foods is typically explained using traditional product attributes like price, freshness, and taste. However, these factors fail to address more socially-based motivations or barriers to purchases. We administered a survey at two farmers’ markets (FMs) in Florida. The survey included: (1) respondents’ local produce purchases; (2) perceived cost and difficulty in accessing those products; (3) a Likert scale that measured attitudes toward local food; (4) a willingness to pay measure; (5) a definition of local by distance and ownership; and (6) frequency of produce purchases from traditional and alternative venues. A two-stage cluster analysis revealed three distinct …

Family Farming And Economic Cooperation: The Emergence And Decline Of Agrarian Condominios In Southern Brazil, Flavio Sacco Dos Anjos, Eduardo Moyano Estrada, Nadia Vellada Caldas

Journal of Rural Social Sciences

In this work the authors analyze the Condominios as an example of economic cooperation adapted to the characteristics of family farming in the Brazilian state of Santa Catarina. The process of modernization of Brazilian agriculture that took place in the 1960s and 1970s under the military governments is analyzed with special attention to the selective and exclusionary effects this process had on the small farmers, along with a study of the development of cooperativism. The consolidation of macro-cooperative models demonstrated reflect the interests and characteristics of modernized, export-oriented agriculture. The origins and development of Condominios as an alternative to the …
