We performed a ground level geomagnetic survey of Greene County, Ohio in the fall of 1976. The geomagnetic map showed a positive magnetic anomaly running from the northwestern section to the southeastern section of the county while the remainder of the map was relatively undisturbed. We analyzed the localized anomaly of the southeastern section by the Peters methods and by fitting to the model ...
introduction in general, loess sediments are one of the most widespread forms of aeolian sediments. during the past few decades, loess stratigraphy studies played key role in the investigation about global climate changes. these sediments are usually yellowish in color and silt makes 70 to 90 percent of its volume. in iran, loesses outcrop are often in northeast part of south caspian sea. the p...
Organization Democrats far and near acted as if they were ashamed of their own President. His name was barely mentioned in speeches and campaign literature. With an eye to the Gallup polls, which indicated a drop in Mr. Truman’s popularity from a honeymoon percentage of 87 percent to an October brown of 32 percent, they decided then he was to be written off as a loss. Republicans made the most ...
The oil industry uses geomagnetic field information to aid directional drilling operations when drilling for oil and gas offshore. These operations involve continuous monitoring of the azimuth and inclination of the well path to ensure the target is reached and, for safety reasons, to avoid collisions with existing wells. Although the most accurate method of achieving this is through a gyroscop...
In this paper, the trend and determinants of health and poverty among the elderly in rural India is analysed. Two rounds of National Sample Survey (NSS) data for the year 1995-96 and 2004 are employed. The analysis has been done with independent and pooled datasets. Our analysis shows that levels of consumption poverty have declined marginally between 1995-96 and 2004 while increased proportion...
helicopter-borne electromagnetic (hem) is a fast and high resolution airborne electromagnetic (aem) method that is frequently used for imaging of the subsurface resistivity structures. this is a versatile and cost effective method, frequently has used in mineral and groundwater exploration and various environmental problems. modern frequency-domain hem systems utilize small electromagnetic, mag...
A high-resolution aeromagnetic survey over the Cape Roberts Rift Basin: Correlations with seismic reflection and magnetic susceptibility log data" (2007). Related Publications from ANDRILL Affiliates. Paper 21. Summary A high-resolution aeromagnetic survey (altitude 125 m asl, spacing 500 m , area 800 km 2) was carried out in 1994 offshore of Cape Roberts by the GITARA (German ITalian Aeromagne...
We present new results of a survey for weak magnetic fields among DA white dwarfs with inclusion of some brighter hot subdwarf stars. We have detected variable circular polarization in the Hα line of the hot subdwarf star Feige 34 (SP: sdO). From these data, we estimate that the longitudinal magnetic field of this star varies from −1.1 ± 3.2 kG to +9.6 ± 2.6 kG, with a mean of about +5 kG and a...
This is a survey of the current experimental information on some of the interesting issues in neutrino physics: neutrino species, neutrino masses, neutrino magnetic moments, solar neutri-nos, and the atmospheric neutrino anomaly.
