Grass Pellet Bioenergy in the Northeastern USA

Grass pellets are a renewable energy supply that combines low technology/small-scale with local production/consumption for a cost effective energy system. There have been significant recent advances in pellet furnace technology and some pellet stove manufacturers now claim their stoves are capable of burning biomass with 5-6% ash content. Cool-season grasses have not been considered acceptable for pelleting and direct combustion in the past due to high ash content. Rain after harvest, however, has been shown to leach significant amounts of potassium and chlorine from grass (Sander, 1997). High yields are possible under lax harvest management (Cherney et al., 2003), producing grass biomass with potassium content as low as 0.5%. Ash content of cool-season grasses is dependent on species, plant maturity, soil type, leaching before and after cutting, loss of high-ash plant parts, and soil contamination. Our objective was to develop a strategy for practical commercial production of relatively low ash cool-season grass biomass

The Psychology of Gender

This chapter presents examples of active learning activities and how these experiential learning exercises are adapted to the course goals and objectives in a psychology of gender course. The focus of the chapter is on how to best integrate new research findings to the students’ existing knowledge base to create a new appreciation of these complex issues and how they influence each individual’s lif

Incidental memory for spatial information in young children as a function of age and gender

The purpose of the present study was to investigate Hasher and Zacks\u27 (1979,1984) automaticity theory of memory for spatial location information in young children using two incidental memory tasks. A total of 96 three- and fiveyear- olds (48 boys and 48 girls) were randomly assigned to either the manipulation condition (MC) or the observation condition (OC). In order to assess task difficulty, half of the participants manipulated a total of 18 genderstereotyped animal toys (male, female, neutral) and half of the participants a total of 9. After a 2 minute filler task, the participants were instructed to return the animals into their original spaces. Analyses of variance indicated a main effect of age, task difficulty, and gender-stereotype of the animals. Timing of reconstruction, strategy usage as well as implications for the automaticity theory are discussed

Influence of Grass Species and Sample Preparation on Ensiling Characteristics

Laboratory silos are considered a practical method of comparing a number of treatments (O\u27Kiely, 1993). Cherney et al. (2004) reported that vacuum-sealed polyethylene bags effectively ensiled corn silage samples in the laboratory. Grasses, with their inherently higher buffering capacities and lower sugar levels, generally are more difficult to ensile. Objectives were to evaluate the influence of species and chopping (whole vs. shredded) on pH and volatile fatty acid profile of grasses ensiled in vacuum-sealed polyethylene bags and to assess the suitability of this method as a laboratory ensiling method

Evaluation of Narrow-Row Forage Maize in Field-Scale Studies

Some dairy producers in the north-eastern USA adopted narrow row (0.38 m) maize forage production in the mid-1990s because of its 5% dry matter (DM) yield advantage (Cox et al., 1998). These dairy producers, however, continued to plant forage maize at high plant densities (125,000 plants/ha) under high N fertility (225 kg N/ha), despite research that indicated that forage maize had optimum DM yields and forage quality when planted at the recommended 100,000 plants/ha under 175 kg/ha of N fertility (Cox & Cherney, 2001). We evaluated forage maize at 0.38 and 0.76 m (conventional) row spacing under recommended vs. high plant densities and N fertility on a large dairy farm in New York. The objective of the study was to demonstrate to dairy producers that narrow-row forage maize does not require high plant densities and N fertility for optimum DM yield and forage quality

A Coversation with Chris Lowney

Chris Lowney, author of four books on leadership including Heroic Leadership: Best Practices from a 450-Year-Old Company that Changed the World, was interviewed for the inaugural issue of the Creighton Journal of Interdisciplinary Leadership. Heroic Leadershipdiscusses characteristics of great leaders based on principles developed by the Jesuits. In his interview he refers to the four core leadership pillars which are: self-awareness, ingenuity, love, and heroism. He sat down with Dr. Kristin Winford for an interview to talk about leadership and social justice

Administrators\u27 and Faculty\u27s Perceived Online Education Barriers and the Role of Transformational Leadership at a U.S. University in Lebanon

The purpose of this quantitative study was to identify the perceived barriers obstructing the implementation of online education by administrators and faculty at the School of Arts and Sciences of a U.S. university located in Lebanon. The aim of this study was to offer a solution to the most important perceived barriers to online education that informs administrative decisions concerning the appropriate modalities of online instruction that may be implemented at the university. The exploratory factor analysis identified 8 factors out of 35 possible perceived barriers to online education. Faculty and administrators perceived the structural barriers and the pedagogical barriers as very important. Faculty also perceived technical barriers as very important. As a first step toward offering online instruction, the university leadership could offer blended traditional and online education instruction for suitable courses in the School of Arts and Sciences with the goal of assessing feasibility and acceptance. The implementation of this solution may be smoother if facilitated using various leadership styles. In this article, the transformational leadership style is used for implementing the solution to the problem. The findings of this research may be beneficial for other universities in Lebanon and other nations that may be considering the implementation of online education

Non-linear duality invariant partially massless models?

We present manifestly duality invariant, non-linear, equations of motion for maximal depth, partially massless higher spins. These are based on a first order, Maxwell-like formulation of the known partially massless systems. Our models mimic Dirac–Born–Infeld theory but it is unclear whether they are Lagrangian

BRST Detour Quantization

We present the BRST cohomologies of a class of constraint (super) Lie algebras as detour complexes. By giving physical interpretations to the components of detour complexes as gauge invariances, Bianchi identities and equations of motion we obtain a large class of new gauge theories. The pivotal new machinery is a treatment of the ghost Hilbert space designed to manifest the detour structure. Along with general results, we give details for three of these theories which correspond to gauge invariant spinning particle models of totally symmetric, antisymmetric and K\"ahler antisymmetric forms. In particular, we give details of our recent announcement of a (p,q)-form K\"ahler electromagnetism. We also discuss how our results generalize to other special geometries.Comment: 43 pages, LaTeX, added reference
