Discontinuous Galerkin Methods for Numerical Weather Prediction: DG in a large-eddy simulation
No full textThe coarse grid of numerical weather prediction and climate models requires parametrization models to resolve atmospheric processes that are smaller than the grid size. For parametrization development, these processes are simulated by a high resolution model. At the Royal Netherlands MeteorologicalInstitute, the Dutch Atmospheric Large-Eddy Simulation (DALES) is used. This three-dimensional high resolution model uses advection schemes that are too diffusive when steep gradients are present. In this thesis, an advection scheme based on the Discontinuous Galerkin (DG) method is implementedfor DALES.The DG method is known to be dispersive. To remove those non-physical oscillations, the moment limiter of Krivodonova is used. Krivodonova constructed the limiter for one- and two-dimensions. In this thesis the moment limiter and limiting order are derived for three-dimensions. DALES is a model based on the finite difference method and uses operational splitting. Therefore, the DG advection scheme needs a mapping from each cell average to all nodal values that are needed for one DG cell, and a mapping back, which we called mapping a and b respectively. Mappings a that are discussed are taking the cell average as value for all nodal points of the DG cell (cell average a), and taking the L -projection of the cell average to the continuous finite element space (L -projection). This thesis describes mappings b that calculate cell averages of nodal DG values (cell average b)and calculate the cell averages of the tendencies of DG values (cell average of tendency). Using cell average a combined with cell average of tendency, made the DG method as diffusive as the first order upwind scheme. Substituting the cell average a method with the L -projection, the DG method becamevery dispersive, meaning that there was not enough diffusion. At last, cell average b was tested with the L -projection. Its numerical results showed that the speed of the advection was slower than the theoretical velocity. Therefore, a method is suggested which does not need mappings. An option couldbe a supergrid that takes multiple DALES cells as a DG cell.Applied Mathematic
Factors associated with dairy farmers' satisfaction and preparedness to adopt recommendations after veterinary herd health visits
No full textHerd health and production consultancy are important aspects of the modern dairy veterinary practice; therefore, veterinary farm visits will likely be more successful if veterinary practitioners communicate effectively and meet farmers' expectations. Objectives were to assess dairy farmers' satisfaction with veterinary advisors and their perceived preparedness to adopt veterinary advice. Furthermore, we assessed whether farmers' satisfaction and preparedness to adopt advice were associated with specific predictor variables; that is, general (demographic) factors of veterinarians or farmers, communication tools used by veterinarians, and veterinarians' affective attributes during the farm visit. Audio-video recordings of 14 dairy veterinarians during 70 herd health and production management farm visits were analyzed using the Roter interaction analysis system. Demographic data, farmers' satisfaction, and farmers' preparedness to adopt advice were obtained by using questionnaires. Overall, farmers were satisfied with their veterinarian's communication during farm visits and 58% of farmers felt "absolutely" prepared to follow veterinary recommendations. Based on multivariable regression analysis, farmers' satisfaction was positively associated with their level of education and the amount of talk the veterinarian dedicated to counseling the farmer. However, satisfaction was negatively association with the ratio between veterinarian talk and farmer talk. In addition to various demographic variables, farmers' preparedness to adopt veterinary advice was positively associated with their satisfaction. Other predictor variables for farmers' preparedness to follow recommendations included increased veterinary counseling and frequent herd data discussions, whereas there was a negative relationship between number of farmer questions and dominance of the veterinarian during the farm visit. Identification of factors influencing farmers' satisfaction and preparedness to adopt advice will make veterinary communication more effective and could inform training of veterinarians in communication
An evaluation study of the biomedical careers program at Robert Wood Johnson Medical School
No full textThe Biomedical Careers Program (BCP) began 35 years ago at Robert Wood Johnson Medical School as an effort to provide a pipeline to medical school for students from racial, ethnic, and economic groups that are underrepresented in medical careers. Over the years, the program has expanded to include preparation for admission to a wide variety of health professions careers, but the primary purpose was and continues to be preparation for matriculation into medical school. This evaluation is the first empirical study of the medical school matriculation outcomes of the BCP program and will provide a foundation for further exploration and program improvement. Sample The evaluation study looks at the medical school enrollment outcomes for 456 students who are receiving support from the Educational Opportunity Fund of New Jersey and applied for admission to the BCP program from 1990-2010. Research Questions 1. Do medical school matriculation outcomes vary for EOF students based on BCP attendance? 2. Do medical school matriculation outcomes for EOF students who applied to BCP vary based on race and gender? Methodology The research design was a quasi-experimental retrospective examination of documentary data on the medical school matriculation outcomes of EOF students who applied to BCP, were accepted and either enrolled in BCP or declined admission. This data was collected over the life of the program as part of the ongoing tracking of academic outcomes for the applicants to the program. Additional information about student outcomes was obtained from the National Student Clearinghouse. The analysis was conducted using descriptive and regression model statistical methods. Findings The study showed that Black and Hispanic women who attended the program matriculated into medical school at a statistically significantly larger percentage than those who did not attend BCP. Medical school matriculation outcomes for Black and Hispanic males were not statistically significant. Medical school matriculation outcomes were lower for males from racial categories of White, Asian and Other that attended BCP. Limitation of sample size and parameters of the study affected the results since the study looked at medical school matriculation rate and not medical school acceptance rate.Ed.D.Includes bibliographical referencesby Cindy L.

Clinical communication patterns of veterinary practitioners during dairy herd health and production management farm visits
No full textEffective communication with clients is an important skill for veterinary practitioners and is linked to clients' satisfaction with the consultancy and adherence to medical advice. Detailed description of veterinary communication styles in companion animal contexts has added to the communication knowledge base and informed veterinary curricula and postgraduate education programs. The objective here was to describe veterinary practitioners' communication patterns during dairy herd health and production management farm visits. Fourteen veterinarians in Alberta and Ontario, Canada, were provided with action cameras (Hero3 black edition; GoPro Inc., San Mateo, CA) and recorded 3 to 7 farm visits each. The resulting 70 audio-video recordings were analyzed using the Roter Interaction Analysis System. Additionally, demographic variables were obtained from study participants to investigate associations of these variables with communication patterns. Intraclass correlation coefficients were calculated for communication units, and multilevel negative binomial regression was used to compare communication patterns between demographic groups. Additionally, the relationship-centeredness of interactions was evaluated and compared between groups using linear regression models. Communication patterns varied considerably among recordings of the same veterinarian interacting with different clients. However, most veterinary talk focused on farmer education, counseling, and building a relationship, whereas especially open-ended questions were rare. When discussion revolved around health issues of an individual animal, veterinarians used less social talk but focused more on biomedical information gathering. Veterinarians' age and sex and the length of the veterinarian-farmer relationship had limited association with communications; however, if the farmer and veterinarian were both male, the conversation was more relationship centered. Communication of veterinarians with previous communication training was very similar to that of those without training. Detailed description of veterinary practitioners' communication patterns on dairy farms will contribute to establishing the importance of communication as a clinical skill and is critical to identifying unique aspects of veterinary on-farm communication
Generation and characterization of murine alternatively activated macrophages
No full textThe chapter, "Generation and characterization of murine alternatively activated macrophages" was written by the listed authors including Shelley B. Weisser (Douglas College Faculty). Part of the "Methods in Molecular Biology (Methods and Protocols)" book series (MIMB, volume 946): For over 35 years, biological scientists have come to rely on the research protocols and methodologies in the critically acclaimed Methods in Molecular Biology series. The series was the first to introduce the step-by-step protocols approach that has become the standard in all biomedical protocol publishing. Each protocol is provided in readily-reproducible step-by step fashion, opening with an introductory overview, a list of the materials and reagents needed to complete the experiment, and followed by a detailed procedure that is supported with a helpful notes section offering tips and tricks of the trade as well as troubleshooting advice. These hallmark features were introduced by series editor Dr. John Walker and constitute the key ingredient in each and every volume of the Methods in Molecular Biology series. Tested and trusted, comprehensive and reliable, all protocols from the series are indexed in PubMed.
Book "Basic Cell Culture Protocols": At some point in their careers, virtually every scientist and technician, as well as many medical professionals, regardless of their area of specialization have a need to utilize cell culture systems. Updating and significantly expanding upon the previous editions, Basic Cell Culture Protocols, Fourth Edition provides the novice cell culturist with sufficient information to perform the basic techniques, to ensure the health and identity of their cell lines, and to be able to isolate and culture specialized primary cell types. The intent of this extensive volume is to generate a valuable resource containing clear methodologies pertinent to current areas of investigation, rather than attempting to educate cell culturists on specific cell types or organ systems. Written in the highly successful Methods in Molecular Biology™, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
Comprehensive and up-to-date, Basic Cell Culture Protocols, Fourth Edition compiles the essential techniques needed to approach this vital laboratory activity with full success.
Book Chapter: Macrophages play a key role in the innate immune response and help to direct the acquired immune response. Early in the innate immune response, they produce reactive oxygen species and pro-inflammatory cytokines and chemokines to drive inflammation and are referred to as “classically activated” or “killer” macrophages (M1). During the resolution phase of inflammation, they switch to what is known as an “alternatively activated” phenotype or “healer” macrophage (M2) and contribute to debris scavenging, angiogenesis, and wound healing. M1 macrophages are activated by treatment with IFNγ or LPS and M2 macrophages are activated by treatment with Th2 cytokines IL-4 or IL-13 and the M2 phenotype switch can be enhanced by IL-10. Macrophages can also be skewed during differentiation in vitro, and the resultant phenotype depends upon the cytokine provided to support their differentiation. In murine macrophages, MCSF promotes differentiation to an M1 phenotype, GM-CSF promotes differentiation to an M2 phenotype and IL-3 promotes differentiation into a profoundly M2 skewed phenotype. A defining feature of the phenotype of murine M1 versus M2 macrophages is how they metabolize L-arginine. In response to an inflammatory stimulus like LPS, M1 macrophages produce inducible nitric oxide synthase (iNOS) which uses L-arginine as a substrate to produce nitric oxide (NO). M2 macrophages constitutively produce the enzyme arginase I (argI), which sequesters L-arginine from iNOS and results in the production of ornithine and downstream polyamines and L-proline. M1 macrophages also produce relatively higher levels of pro-inflammatory IL-12 and lower levels of anti-inflammatory IL-10 relative to M2 macrophages. In this chapter, we describe in vitro derivation of polarized bone marrow macrophages and methods to analyze the resulting phenotype including Q-PCR, Western blotting, and enzyme assays to determine argI and iNOS expression and activity, as well as production of IL-12p40 and IL-10 and determination of IL-12/IL-10 ratios. Production of iNOS, NO, IL-12p40, and IL-10 are measured after treatment with LPS.book chapterPublished.IL-10IL-12p40Arginase INitric oxideInducible nitric oxide synthesisIL-4IL-3Granulocyte macrophage colony stimulating factorMacrophage colony stimulating factorBone marrow derived macrophagesMacrophage phenotypeMacrophage polarizationAlternative activatio
