Scaling relations from scale model experiments on equilibrium accretionary beach profiles
Movable bed, scale model experiments were conducted at three length scales, 1/8.5, 1/10 and 1/11, in a 90 ft-long wave tank to study scale effect and equilibrium profile characteristics under sinusoidal, accreting wave action. Geometric similarity, deep water wave steepness, wave Froude number, densimetric Froude number, and particle Reynolds number were preserved by selecting the same sediment and fluid in the model and prototype. Wave height was measured with parallel-wire resistance gauges wh
Case study of a professional development program: meaningful technology integration in secondary edu
This case study investigated the effects of the design, development, implementation, and evaluation of a professional development program to facilitate the meaningful integration of technology into the curriculum for secondary teachers at a large suburban school. This study addressed the problem of the high cost of technology for a district that had yielded disappointing levels of meaningful technology integration in the teaching and learning process. The professional development program was bas
Numerical simulation of chlorine disinfection processes in non-ideal reactors
The efficacy of disinfection processes in water purification systems is governed by several key factors including reactor hydraulics, disinfectant chemistry and microbial inactivation kinetics. The objective of this work was to develop a computational fluid dynamics (CFD) model to predict flow structure, mass transport, chlorine decay and microbial inactivation in a continuous flow reactor. The significance of this dissertation is that comprehensive 3D numerical model was developed to address al
The United States Postal Service: A Case Study of Large Scale Government Transformation
The challenge of replacing the baby-boomer generation of employees is beginning in government agencies as they face a “tsunami” of retirements. This generation forms the core of middle managers or supervisors who are essential to providing the continuity in government organizations that serve the needs of citizens on a daily basis, or most critically in times of crisis.
This same generation of government employees worked through decades of change in public administration. The 1980s privat
Improved Critical Thinking Skills as a Result of Direct Instruction and Their Relationship to Academ
This experimental study examined the effect of direct instruction in critical thinking on the critical thinking ability and academic achievement of Freshman students being tutored in repeat courses at a rural southeastern Pennsylvania university. This study used the Thinker's Guides, based on Richard Paul's model of critical thinking, and the Rationale Argument Mapping Program, based on the research of Tim van Gelder. Subjects' abstract reasoning and problem solving skills were measured by the C
Parenting Education for Low-Income Parents of Preschoolers: What is the Most Effective Approach?
Parent education programs have been found to be effective interventions for lower-socioeconomic families. (Baydar, Reid, & Webster-Stratton, 2002). Although research has reliably reported that any parent training is better than no parent training (Helm & Kozloff, 1986), the effectiveness of group parent education programs which emphasize relational improvement is largely unknown. The present study attempted to address this question by comparing archival data collected between the years 1999 and
Healthy People 2010 disease prevalence in the Marshfield Clinic Personalized Medicine Research Proje
Objectives: The purpose of this study was to estimate the prevalence of Healthy People 2010 disease conditions in a large population-based cohort in central Wisconsin (WI, USA) and to consider how these conditions can be prioritized for research based on the use of healthcare services, the prevalence of various disease states and the resulting study power.
Methods: Healthy People 2010 diagnoses were estimated for participants in
the Personalized Medicine Research Project (PMRP), a large popula
Prostate Cancer Screening Decision Making Under Controversy: Implications for Health Promotion Pract
Prostate cancer is a major health problem for U.S. men and is characterized by paradoxes and controversies. Despite the wide availability of the prostate-specific antigen (PSA) test, prostate cancer screening remains a controversial practice mainly because the direct impact of screening on mortality is not yet proven. As the relative value of screening, early detection, and treatment strategies continue to be debated, glaring racial-ethnic disparities persist with African American men experienci
The Role of Community Advisory Boards: Involving Communities in the Informed Consent Process
Ethical research involving human subjects mandates that individual informed consent be obtained from research participants or from surrogates when participants are not able to consent for themselves.The existing requirements for informed consent assume that all study participants have personal autonomy; fully comprehend the purpose, risks, and benefits of the research; and volunteer for projects that disclose all relevant information. Yet contemporary examples of lapses in the individual informe
Health inequalities and the welfare state: perspectives from social epidemiology
It might be assumed that welfare states that have done so much to reduce inequality of opportunity have also reduced inequality of health outcomes. While great advances have been seen in reducing the rates of many diseases in welfare states, disparities in health have not been eliminated. Is it the case that lowering risks overall will leave disparities that cannot be remediated, and that such efforts are at the point of diminishing returns? The evidence suggests that this is not true. Instead t
The end and the beginning:a model for analyzing visual/verbal news broadcasts of protest coverage
This project brings together two areas of prior research: framing and visual rhetoric. Framing as it relates to news coverage of protests constitutes the core theoretical foundation. In using prior research by McLeod, Gitlin, and Lee, we see how news coverage can potentially bias an audience against protestors. However, this research focuses extensively on newspapers or transcripts of televised news. Consequently, by combining visual theories like semiotics, gestalt, and film theory into a visua

4 Other influences on evolution
In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.
Cardiology Examination - Carotid Pulse
Examine the carotid pulse.
1. Observe for carotid pulsations.
2. Place your fingers behind the patient's neck and compress the carotid artery on one side with your thumb at or below the level of the cricoid cartilage. Press firmly but not to the point of
discomfort. Avoid compressing both sides at the same time. This could cut off the blood supply to the brain and cause syncope. Avoid compressing
the carotid sinus higher up in the neck. This could lead to bradycardia and depressed bloo
Cardiology Examination - Auscultation for bruits
If the patient is middle-aged or elderly, you should auscultate for bruits. A bruit is often, but not always, a sign of arterial narrowing and risk of a stroke.
- Place the bell of the stethoscope over each carotid artery in turn. You
may use the diaphragm if the patient's neck is highly contoured.
- Ask the patient to stop breathing for a moment.
- Listen for a blowing or rushing sound-a bruit. Do not be confused by heart sounds or murmurs transmitted from the chest.
L’utilisation de la propriété intellectuelle comme moteur de développement
Les premières ”Rencontres lorraines de la propriété intellectuelle” tenues à Metz en mai 2008 avaient été consacrées à la propriété intellectuelle face au défi de la mondialisation.
L’édition 2009 de ces Rencontres, organisée le 6 octobre 2009 à Nancy, s’est concentrée sur la filière « fibres et éco-matériaux », laquelle, que ce soit à travers le bois, le textile, le papier, les composites ou encore les marchés utili
Physique et médecine : l'imagerie médicale (video)
L'imagerie médicale a sans aucun doute entraîné ces vingt dernières années une transformation radicale dans la façon d'aborder le diagnostic et le suivi thérapeutique. Un diagnostic de localisation d'une lésion cérébrale qui nécessitait un examen clinique long et minutieux par un neurologue expérimenté se fait aujourd'hui avec une précision millimétrique grâce au scanner ou à l'imagerie par résonance magnétique (IRM). Là où le maître entouré de ses élèves démontrait
