Growth Of Well-Defined Zno Microparticles By Hydroxide Ion, Ruth Mcbride, Declan Mccormack, John Kelly

Articles

The morphology of the microcrystalline zinc oxide formed by reaction of zinc salts with sodium hydroxide depends critically on the reaction conditions. To understand this, the nature of the solid product has been probed by scanning electron microcopy (SEM) and X-ray diffraction (XRD) and the concentration of zinc remaining in the solution has been determined at regular intervals throughout the reaction. Two general preparative procedures have been followed. The first, which involves simply heating an aqueous solution containing Zn(NO3)2 (0.025 M) and sodium hydroxide (0.375 M) to 101 uC and maintaining it at that temperature for periods of up to …

Autonomous Field-Deployable Wildland Fire Sensors, Robert Kremens, Jason Faulring, A. Gallagher, A. Seema, Anthony Vodacek

Articles

An Autonomous Fire Detector (AFD) is a miniature electronic package combining position location capability [using the Global Positioning System (GPS)], communications (packet or voice-synthesized radio), and fire detection capability (thermal, gas, smoke detector) into an inexpensive, deployable package. The AFD can report fire-related parameters, like temperature, carbon monoxide concentration, or smoke levels via a radio link to firefighters located on the ground. These systems are designed to be inserted into the fire by spotter planes at a fire site or positioned by firefighters already on the ground. AFDs can also be used as early warning devices near critical assets in …

Articles

The MPEG-7 standard provides a framework of standardized tools that can be used to describe and efficiently manage multimedia content. Visual descriptors include color, texture, shape and motion. In this paper, we address the hardware implementation of MPEG-7 motion descriptors using Handel-C. In particular, descriptors for motion intensity and spatial distribution of motion activity are generated and implemented.

A Web-Based Distance-Learning Course In Structural Analysis, Abi Aghayere

Articles

There are some asynchronous web-based courses available in the civil engineering technology field but to the author’s knowledge, very few courses exist in structural analysis and design. The advantages of web-based online learning include flexibility and the ability to accommodate various learning styles such as visual and auditory learners, with the visual learning style being the most common among people of college age and older. The Civil Engineering Technology program at RIT recently developed a suite of web-based courses as part of the new Certificate in Structural Design. The online courses available include Structural Analysis, Timber Design, Reinforced Concrete Design, …

Landsat-7 Etm+ Radiometric Stability And Absolute Calibration, Brian L. Markham, John L. Barker, Julia A. Barsi, Ed Kaita, Kurtis J. Thome, Dennis L. Helder, Frank D. Palluconi, John R. Schott, Pat Scaramuzza

Articles

Launched in April 1999, the Landsat-7 ETM+ instrument is in its fourth year of operation. The quality of the acquired calibrated imagery continues to be high, especially with respect to its three most important radiometric performance parameters: reflective band instrument stability to better than ±1%, reflective band absolute calibration to better than ±5%, and thermal band absolute calibration to better than ± 0.6 K. The ETM+ instrument has been the most stable of any of the Landsat instruments, in both the reflective and thermal channels. To date, the best on-board calibration source for the reflective bands has been the Full …

Children's Understanding Of Television Advertising Intent, Margaret-Anne Lawlor, Andrea Prothero

Articles

Over the last three decades, a substantial body of research has accumulated seeking to address how exactly advertising, and in particular, telelvision advertising, influences children. Yet, given the diversity of methodologies used and the findings presented, it has been suggested that a common consensus on how exactly advertising affects children has not been reached. This paper presents a brief overview of the literature addressing chidlren's understanding of advertising with a view to identifying the contributions to date in this area and the accompanying gaps, omissions and under-resesearched perspectives. Findings are then presented from an exploratory study of eight and nine …

The Internet And The Persistence Of Law, Justin Hughes

Articles

Since legal commentators first confronted cyberspace, three broad stories have emerged to describe the interrelation of law and the Internet: the "no-law Internet," the "Internet as a separate jurisdiction," and Internet law as "translation" of familiar legal concepts. This Article reviews these stories, focusing on how ongoing "translation" is giving way to a growing convergence in Internet law. The Article makes the case for convergence among legal responses to cyberspace and proposes a basic taxonomy for different models of convergence. With this taxonomy, the Article examines the ways in which convergence is occurring, as well as its effects on both …

Real-Life Perspectives: Quality Of Life Assessments, Susan Foster, Kerstin Moller

Articles

This article explores the ways in which deaf college students who are members of minority racial groups think about and describe their identities. In-depth, semi structured interviews with 33 deaf students of Asian American, Hispanic American, and African American background were analyzed for themes regarding the self-reported identities of respondents. Results suggest that each person is a constellation of many parts, some of which are stronger than others but any of which can be drawn out in response to a particular set of circumstances, resulting in a contextual and interactive model of identity. Four factors arc described as central to …

A Qualitative Study Of Teachers' Acceptance Of A Speech-To-Text Transcription System In High School And College Classrooms, Lisa Elliot, Susan Foster, Michael Stinson

Articles

Student success using an assistive technology may be partially attributed to educators' acceptance of the technology. High school and college educators in New York and California participated in a qualitative study of the implementation of a speech-to-text support service for students who are deaf or hard of hearing. Educators' interviews were analyzed using criteria from Rogers (1995) model of diffusion of innovations. Educators accepted the support service due to its relative advantage to other notetaking services, perceived simplicity of the system, and perceived potential for students. Acceptance was less clear-cut in the domains of compatibility and trialability. Educators were less …

The research is case study based and reports the findings of a study undertaken in Courtown, a small seaside resort in the Republic of Ireland. Specifically, it investigates the role that holiday home owners played in a controversy that arose with respect to developing tourism accommodation in an area of …

Symbols, Practices And Myth-Making: Cultural Perspectives On The Wexford Festival Opera, Bernadette Quinn

Articles

In recent decades geographers have paid increasing attention to festivals. They have construed festivals as important practices through which people connect with their place and as authored landscapes designed to promote particular sets of values and attach specific meanings to place. Tourism influences the processes and dynamics ongoing in festival settings and this paper seeks to unravel some of the complex ways in which it influences the reproduction of cultural meanings there. It draws on research conducted on the Wexford Festival Opera in the Republic of Ireland and analyses the symbolism, practices and meanings found to be associated with the …
