Pesticides on Tobacco: Federal Activities to Assess Risks and Monitor Residues

A letter report issued by the General Accounting Office with an abstract that begins "Pesticides play a significant role in increasing production of tobacco, food, and other crops by reducing the number of crop-destroying pests. However, if used improperly, pesticides can have significant adverse health effects. GAO was asked to (1) identify the pesticides commonly used on tobacco crops and the potential health risks associated with them, (2) determine how the Environmental Protection Agency (EPA) assesses and mitigates health risks associated with pesticides used on tobacco, and (3) assess the extent to which federal agencies regulate and test for pesticide residues on tobacco."

Frequency Control Concerns in the North American Electric Power System (open access)

Frequency Control Concerns in the North American Electric Power System

This paper examines the relationship between system frequency, reliability and markets. It was prompted by the frequency deviations recently experienced at 2200 hours daily but is more generally concerned with the question of what frequency control is necessary. The paper does not provide new information or document new research. Nor is it intended to educate readers concerning power system engineering. Instead, the purpose is to reexamine well known truths concerning the power system and to freshly explore the basic relationship between frequency, reliability and markets: stepping back, if you will, to see if we are collectively missing something. The concern of this paper is with frequency and reliability. Off-nominal frequency can impact reliability and markets efficiency (as we are using the term here) in four ways. It could damage equipment (generation, transmission, or load). It could degrade the quality of the product being delivered to end users (too low and lights would flicker unacceptably, for example). It could result in the collapse of the power system itself (by triggering protective system actions, for example). Or it could result in overloading transmission lines as various generators try to restore system frequency impacting markets efficiency. Often these causes operate in concert. Generator …

Delamination Failure Investigation for Out-Of-Plane Loading in Laminates (open access)

Delamination Failure Investigation for Out-Of-Plane Loading in Laminates

In contrast to failure approaches at the lamina level or the micromechanics level the present work concerns failure characterization at the laminate level. Specifically, attention is given to the ultimate failure characterization for quasi-isotropic laminates. This is in further contrast to the commonly used approaches for initial damage or progressive damage. It is shown that the analytical failure forms decompose into two modes, one for out of plane, delamination type failure and one for in plane, fiber controlled type failure. The work here is mainly given over to the delamination mode of failure. Experimental results are presented for laminates in this mode of failure. These results are then integrated with the analytical forms to give a simple criterion for delamination failure.

Proteins as paradigms of complex systems. (open access)

Proteins as paradigms of complex systems.

The science of complexity has moved to center stage within the past few decades. Complex systems range from glasses to the immune system and the brain. Glasses are too simple to possess all aspects of complexity; brains are too complex to expose common concepts and laws of complexity. Proteins, however, are systems where many concepts and laws of complexity can be explored experimentally, theoretically, and computationally. Such studies have elucidated crucial aspects. The energy landscape has emerged as one central concept; it describes the free energy of a system as a function of temperature and the coordinates of all relevant atoms. A second concept is that of fluctuations. Without fluctuations, proteins would be dead and life impossible. A third concept is slaving. Proteins are not isolated systems; they are embedded in cells and membranes. Slaving arises when the fluctuations in the surroundings of a protein dominate many of the motions of the protein proper.

FEASIBILITY ANALYSIS FOR INSTALLING A CIRCULATING FLUIDIZED BED BOILER FOR COFIRING MULTIPLE BIOFUELS AND OTHER WASTES WITH COAL AT PENN STATE UNIVERSITY

The Pennsylvania State University, utilizing funds furnished by the U.S. Department of Energy's Biomass Power Program, investigated the installation of a state-of-the-art circulating fluidized bed boiler at Penn State's University Park campus for cofiring multiple biofuels and other wastes with coal, and developing a test program to evaluate cofiring biofuels and coal-based feedstocks. The study was performed using a team that included personnel from Penn State's Energy Institute, Office of Physical Plant, and College of Agricultural Sciences; Foster Wheeler Energy Services, Inc.; Foster Wheeler Energy Corporation; Parsons Energy and Chemicals Group, Inc.; and Cofiring Alternatives. The activities included assessing potential feedstocks at the University Park campus and surrounding region with an emphasis on biomass materials, collecting and analyzing potential feedstocks, assessing agglomeration, deposition, and corrosion tendencies, identifying the optimum location for the boiler system through an internal site selection process, performing a three circulating fluidized bed (CFB) boiler design and a 15-year boiler plant transition plan, determining the costs associated with installing the boiler system, developing a preliminary test program, determining the associated costs for the test program, and exploring potential emissions credits when using the biomass CFB boiler.

Reconstruction of mechanically recorded sound by image processing (open access)

Reconstruction of mechanically recorded sound by image processing

Audio information stored in the undulations of grooves in a medium such as a phonograph record may be reconstructed, with no or minimal contact, by measuring the groove shape using precision metrology methods and digital image processing. The effects of damage, wear, and contamination may be compensated, in many cases, through image processing and analysis methods. The speed and data handling capacity of available computing hardware make this approach practical. Various aspects of this approach are discussed. A feasibility test is reported which used a general purpose optical metrology system to study a 50 year old 78 r.p.m. phonograph record. Comparisons are presented with stylus playback of the record and with a digitally re-mastered version of the original magnetic recording. A more extensive implementation of this approach, with dedicated hardware and software, is considered.

Reduction of Constraints: Phase 2 Experimental Assessment for Sludge-Only Processing (open access)

Reduction of Constraints: Phase 2 Experimental Assessment for Sludge-Only Processing

The homogeneity constraint is currently used by the Defense Waste Processing Facility (DWPF) to discriminate compositions that are likely to result in glasses containing glass-in-glass amorphous phase separation from compositions that are likely to be homogeneous. The durability of glasses containing amorphous phase separation can be unpredictable so a phase separation discriminator was developed and implemented as part of the Product Composition Control System (PCCS) to avoid processing unacceptable phase separated glasses in the DWPF. However, implementation of the homogeneity constraint (i.e., the amorphous phase separation discriminator) has resulted in an overly restrictive operating region for the DWPF (i.e., it has limited processing in regions that would have resulted in acceptable glasses being produced). Therefore, studies were initiated to determine if the homogeneity constraint could be eliminated while still allowing processing flexibility for DWPF during sludge-only processing. At the same time, the alternative constraint must not compromise product quality.
