    The sample of water was taken from a well in the town of Sangerfield, Oneida County, New York, about a mile and a half south of the village of Waterville. It is located on the flat land in the bottom of the Sangerfield valley near the headwaters of Chenango River

    Evaluation of Stress Corrosion Cracking Susceptibility Using Fracture Mechanics Techniques, Part 1

    Get PDF
    Stress corrosion cracking (SSC) tests were performed on 13 aluminum alloys, 13 precipitation hardening stainless steels, and two titanium 6Al-4V alloy forgings to compare fracture mechanics techniques with the conventional smooth specimen procedures. Commercially fabricated plate and rolled or forged bars 2 to 2.5-in. thick were tested. Exposures were conducted outdoors in a seacoast atmosphere and in an inland industrial atmosphere to relate the accelerated tests with service type environments. With the fracture mechanics technique tests were made chiefly on bolt loaded fatigue precracked compact tension specimens of the type used for plane-strain fracture toughness tests. Additional tests of the aluminum alloy were performed on ring loaded compact tension specimens and on bolt loaded double cantilever beams. For the smooth specimen procedure 0.125-in. dia. tensile specimens were loaded axially in constant deformation type frames. For both aluminum and steel alloys comparative SCC growth rates obtained from tests of precracked specimens provide an additional useful characterization of the SCC behavior of an alloy

    Spacecraft design sensitivity for a disaster warning satellite system

    Get PDF
    A disaster warning satellite (DWS) is described for warning the general public of impending natural catastrophes. The concept is responsive to NOAA requirements and maximizes the use of ATS-6 technology. Upon completion of concept development, the study was extended to establishing the sensitivity of the DWSS spacecraft power, weight, and cost to variations in both warning and conventional communications functions. The results of this sensitivity analysis are presented

    Quantum Mechanics and Linearized Gravitational Waves

    Get PDF
    The interaction of classical gravitational waves (GW) with matter is studied within a quantum mechanical framework. The classical equations of motion in the long wave-length limit is quantized and a Schroedinger equation for the interaction of GW with matter is proposed. Due to its quadrapole nature, the GW interacts with matter by producing squeezed quantum states. The resultant hamiltonian is quite different from one would expect from general principles, however. The interaction of GW with the free particle, the harmonic oscillator and the hydrogen atom is then studied using this hamiltonian.Comment: 24 pages, written in REVTE

    У статті здійснено комплексний аналіз північноамериканської історіографії діяльності УПА. Виходячи з методологічних підходів, дослідницьких технік та світоглядних позицій було виокремлено три групи північноамериканських дослідників: емігрантську, діаспорну та американську. Автор зосереджується на детальному аналізі часу створення і чисельності УПА та Волинській трагедії.The article is dedicated to the complex analysis of the North-American historiography of the UPA activity. According to methodological approaches, investigation technique, and world outlook of the authors, the three groups of North-American researchers were singled out: the emigrant, the diaspora and the American one. The author analyzes in detailed the time of creation and number of the UPA troops as well as the Volynian tragedy
