Noise Measurements

Tire-road noise levels for Ohio Department of Transportation pavement types were investigated to provide an additional criterion for pavement selection in noise-sensitive areas. Tire-road noise measurements were conducted in accordance with the International Organization for Standardization’s statistical pass-by method (ISO 11819-1)—the first use of this standard in the United States. A statistical pass-by index (SPBI) was determined for each pavement test, which enabled the ranking of the pavement types according to tire-road noise levels, as well as a means of comparing results with other studies conducted according to the standard. There was a difference of 6.7 dB between the lowest (open-graded asphalt) and the highest (random-transverse-grooved concrete) SPBI for all of the pavements measured. Additionally, the data were analyzed to produce reference energy mean emission levels for future use with traffic-noise prediction modeling.

Certification Requirements

Within the next five years, small package delivery drones and larger human passenger drones will become the next mode of transportation to fill our environment with noise. They are already being used in test markets around the world to gauge community acceptance of the concept; none the least of which being the noise generated by these drones. In fact, along with safety, noise is the prime concern for gaining acceptance and regulatory approval for widespread use of drones. Title 14 CFR Part 36 contains FAA's current certification requirements for drone flyover noise at the source. But what about receiver noise criteria? This paper will describe some of the prototype drones in use today, the major manufacturers and drone delivery services already well into development, and the current federal regulatory setting for community noise in the United States for various modes of transportation. The paper concludes with a recommended noise criteria approach, for FAA to consider adopting, that would provide a balance between the drone manufacturers' need to produce noise with the community's need for peace and quiet.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

Quantitative Image

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
