original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

We present direct ground based observations of the plasma flow sunward and tailward of the nucleus of comet P/Swift-Tuttle. The observations a•e long-slit high resolution spectra of the H•.O + emission centered at 6199]t with a velocity resolution of about 7 km s -• (FWHM) and a spatial resolution of about 104 km at the comet. Emission is visible from just inside the predicted position of the c...

The aim of this paper is to present an analytical solution for the spin motion equations of spin-stabilized satellite considering only the influence of solar radiation torque. The theory uses a cylindrical satellite on a circular orbit and considers that the satellite is always illuminated. The average components of this torque were determined over an orbital period. These components are substi...

We measure the large-scale intrinsic alignments of galaxy clusters in the Sloan Digital Sky Survey (SDSS) using subsets of two cluster catalogues: 6625 clusters with 0.1 < z < 0.3 from the maxBCG cluster catalogue (7500 deg2) and 8081 clusters with 0.08 < z < 0.44 from the adaptive matched filter catalogue (6500 deg2). We search for two types of cluster alignments using pairs of clusters: the a...
