The Use of Demolition Wood in Papermaking

The reason for this study came from three factors affecting the paper industry as well as society as a whole. These factors are decreasing landfill space, increasing tipping fees, and increasing demands for alternative fiber sources. In the United States, approximately 9.8 million tons of demolition wood waste is landfilled per year. Increasing governmental regulations which require greater amounts of secondary fiber to be used in papermaking are forcing the industry to consider alternative fiber options. The seven steps in the procedure include: rough wood, wood chips, kraft pulping, fiber refining, screening, handsheets, and testing. The four types of wood involved are a 50 year old house wood, a 100 year old barn wood, a kiln-dried wood, and a red pine green wood. All wood types are pine. The strength test (tensile, burst, tear) revealed that demolition wood fiber is strong enough to be considered as a secondary fiber source. The average value obtained for tear from the demolition wood is 13.7 (mN m2/g). The average values for burst and tensile are 20.3 psi and 4.18 km, respectively. In fact, the values obtained from the old wood are comparable to those obtained by Kleppe for a green wood pine(4). Drawbacks to its use include containment removal, probable bleaching limitations, obtaining the wood, and labor/energy requirements. The resource may best be utilized by having a demolition company deliver the wood, pulp, screen, and refine the wood separately, and have the fibers metered in at know quantities at the blend chest within the paper mill. Ultimately the use of this source becomes a function of society\u27s focus on the green movement and regulations imposed on the industry by the government

For a Voice and the Vote

During the summer of 1964, hundreds of American college students descended on Mississippi to help the state\u27s African American citizens register to vote. Student organizers, volunteers, and community members canvassed black neighborhoods to organize the Mississippi Freedom Democratic Party (MFDP), a group that sought to give a voice to black Mississippians and demonstrate their will to vote in the face of terror and intimidation. In For a Voice and the Vote, author Lisa Anderson Todd gives a fascinating insider\u27s account of her experience volunteering in Greenville, Mississippi, during Freedom Summer, when she participated in organizing the MFDP. Innovative and integrated, the party provided political education, ran candidates for office, and offered participation in local and statewide meetings for blacks who were denied the vote. For Todd, it was an exciting, dangerous, and life-changing experience. Offering the first full account of the group\u27s five days in Atlantic City, the book draws on primary sources, oral histories, and the author\u27s personal interviews of individuals who were supporters of the MFDP in 1964.https://uknowledge.uky.edu/upk_cr/1007/thumbnail.jp

THE EFFECT OF MINDFUL LISTENING INSTRUCTION ON LISTENING SENSITIVITY AND ENJOYMENT

The purpose of this study was to examine the effect of Mindful Listening Instruction on Music Listening Sensitivity and Music Listening Enjoyment. The type of mindfulness investigated in this study was of the social-psychological type, which shares both commonalities with and distinctions from meditative mindfulness. Enhanced context awareness, openness to new information, situation in the present, awareness of novel distinctions, and awareness of multiple possible perspectives (cognitive flexibility) are components of social-psychological mindfulness. A pretest-posttest control group design was used for this study. Two different age groups of students were studied: fourth-grade students (N = 42) and undergraduate non-music major college students (N = 48). The fourth-grade participants in this study were selected from an elementary school in a large city in the Northeastern United States. The college students were selected from a large university in the Southeastern United States. Participants were randomized into either the experimental or control group. Gordon’s Intermediate Measures of Music Audiation and Advanced Measures of Music Audiation were used as a pretest for fourth-grade students and college students, respectively. The results showed no statistically significant differences between the experimental and control groups. Student demographical information was also collected and reported. The treatment consisted of 10 lessons for fourth-grade students. Five of the 10 lessons were used with the college students. For each age level, participants in both groups, Mindful Listening and Control, received instruction using listening-map-based and non-listening-map-based lessons from the Share the Music textbook series. Students in the Mindful Listening groups also received listening instructions designed to promote mindful listening. Music Listening Sensitivity was measured using the phrasing test from the Sensitivity portion of Gordon’s Music Aptitude Profile (MAP-P), as well as the researcher-created Anderson Test of Music Listening Sensitivity (ATMLS). Music Listening Enjoyment was measured using students’ ratings of their Listening Enjoyment after each lesson on a seven-point Likert-type scale. Results indicated that Mindful Listening Instruction yielded higher scores, which were statistically significant (at α = .05), for Music Listening Sensitivity (as measured by both the ATMLS and the MAP-P) and Music Listening Enjoyment for fourth-grade and college-student participants

Proposal for three Greek papyrological characters

This is a proposal to add three Greek characters to the international character encoding standard Unicode, needed to represent text on papyri. The characters were published in Unicode Standard version 7.0 in June 2014

The Relationship of Motivation Factors to Level of Development In Outdoor Adventure Recreationists

A growing body of empirical studies tests theories of developmental level in a recreation activity. Most are based on two prominent lei­sure theories: specialization (Bryan, 1977, 1979) and amateur/professionalism or serious leisure (Stebbins, 1979, 1992). A parallel group of stud­ies has focused on understanding the developmental levels of outdoor adventure (or risk) receation behavior, primarily using the Adventure Recreation Model (ARM) (Ewert, 1989) as a cornerstone. Both areas of the literature have sought to understand developmental levels in relation to other variables, including motivation. The purpose of this study was to determine the motivation factors that are related to partici­pants\u27 level of development in outdoor adven­ture recreation pursuits. This study will further test the ARM, add to the empirical body of knowledge in the areas of recreation specializa­tion and serious leisure, and integrate these two parallel areas of study

Constructing informative Bayesian map priors: A multi-objective optimisation approach applied to indoor occupancy grid mapping

The problem of simultaneous localisation and mapping (SLAM) has been addressed in numerous ways with different approaches aiming to produce faster, more robust solutions that yield consistent maps. This focus, however, has resulted in a number of solutions that perform poorly in challenging real life scenarios. In order to achieve improved performance and map quality this article proposes a novel method to construct informative Bayesian mapping priors through a multi-objective optimisation of prior map design variables defined using a source of prior information. This concept is explored for 2D occupancy grid SLAM, constructing such priors by extracting structural information from architectural drawings and identifying optimised prior values to assign to detected walls and empty space. Using the proposed method a contextual optimised prior can be constructed. This prior is found to yield better quantitative and qualitative performance than the commonly used non-informative prior, yielding an increase of over 20% in the F2 metric. This is achieved without adding to the computational complexity of the SLAM algorithm, making it a good fit for time critical real life applications such as search and rescue missions

Preface of Bioremediation through Rhizosphere Technology

The use of MICROORGANISMS to remediate environments contaminated by hazardous substances is an innovative technology and an area of intense interest. Although biological technology has been used for decades in wastewater treatment, recent examination of the cost-effectiveness of this technology has led to its application to hazardous chemicals at waste sites. Successes obtained by using the natural metabolic capabilities of bacteria and fungi to clean up soil, sediment, and water have encouraged continued interest and research in bioremediation
