Rochester Fair, September 1930

Trott\u27s Official Score Card for the Friday, September 26, 1930 Rochester Fair race at Cold Spring Park, Rochester, N.H. The card includes the names of race officials and Guy Kendall\u27s handwritten notes recording race details, as well as a photo mounted inside the score card. The score card was printed by Frank G. Trott, an agent with Hartford Live Stock Insurance Co., selling insurance coverage for race horses but was also a reporter covering harness racing for The Boston Globe from 1896-1949

Sulfur reduction in sediments of marine and evaporite environments

Transformations of sulfur in sediments of ponds ranging in salinities from that of normal seawater to those of brines saturated with sodium chloride were examined. The chemistry of the sediment and pore waters were focused on with emphasis on the fate of sulfate reduction. The effects of increasing salinity on both forms of sulfur and microbial activity were determined. A unique set of chemical profiles and sulfate-reducing activity was found for the sediments of each of the sites examined. The quantity of organic matter in the salt pond sediments was significantly greater than that occurring in the adjacent intertidal site. The total quantitative and qualitative distribution of volatile fatty acids was also greater in the salt ponds. Volatile fatty acids increased with salinity

An Analysis of the Telecommunication Performance of a Data Relay Satellite System

The Data-Relay Satellite System (DRSS) has been proposed as a means of providing a communication capability between a number of earth-orbiting space vehicles and the Mission Control Center- Houston (MCC-H) using earth-orbiting synchronous satellites as relay devices. The purpose of this paper is to report the investigation of the performance characteristics of the relay system and to determine the expected communications capabilities of the DRSS operating with Apollo spacecraft systems and with an advanced spacecraft-systems concept. When the DRSS is used with the spacecraft high-gain antenna (Apollo or modified spacecraft), positive circuit margins can be expected for all up-link and down-link, pulse modulated (PM) modes, which include pseudorandom noise (PRN) ranging, telemetry, and voice. Wideband frequency modulated (FM) modes (television or 1-Mbps data dump) have positive circuit margins for the modified spacecraft system configuration; however, only marginal performance can be expected with the Apollo system
