it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
An experiment to search for short-period intensity oscillations in the solar corona was conducted during the total solar eclipse of August 11, 1999 in Esfahan, Iran. The intensity in the continuum, centered about 4700 Å and with a passband having a half-width of 190 Å, was recorded at a counting rate of 5 Hz using six low-noise Hamamatsu R647 photomultiplier tubes. We recorded intensity value...
BACKGROUND Lipoatrophy and metabolic complications of treatment of human immunodeficiency virus (HIV) infection may share common associations with adipose tissue pathology and inflammation. To investigate these relationships, we undertook a large-scale study of adipose tissue, body composition, and metabolic outcomes among HIV-infected adult men at a tertiary hospital HIV cohort during the peri...
Passive seismic methods using earthquakes can be applied for extracting body waves and obtaining information of subsurface structure. To analyze earthquake data, one traditionally uses receiver functions, tomography, and seismic interferometry. In this study, we retrieve reflected body waves by applying seismic interferometry to the recorded ground motion from a cluster of earthquakes. We emplo...
Discussion S waves are seismic body waves meaning they travel through the Earth’s interior. Their velocity is slower than that of P waves, and they are normally the second major phase to be observed on a seismogram, and are therefore also referred to as secondary waves. In the Earth’s crust, S wave velocities are typically 3–4 km/s. S waves are usually larger in amplitude than P waves and may c...
We explore prospects for detecting gravitational waves from stellar-mass compact objects spiraling into intermediate mass black holes (BHs) M approximately 50M to 350M) with ground-based observatories. We estimate a rate for such intermediate-mass-ratio inspirals of <or= 1-30 yr(-1) in Advanced LIGO. We show that if the central body is not a BH but its metric is stationary, axisymmetric, reflec...
Ambient noise correlation is now widely used in seismology to obtain the surface 6 waves part of the Green's function. More difficult is the extraction of body waves from noise 7 correlations. Using 42 temporary broad-band three components stations located on the 8 northern part of fennoscandian region, we identify high frequency (0.5-2 Hz) body waves 9 emerging from noise correlations for inte...
Background. Malnourished infants are small for age and weight. Objectives. Determine profiles in 24-hour energy metabolism in recovering malnourished infants and compare to similarly aged healthy controls. Methods. 10 malnourished infants (58.1 +/- 5.9 cm, 7.7 +/- 5.6 months) were healthy prior to spending 22 hours in the Enhanced Metabolic Testing Activity Chamber for measurement of EE (kcal/m...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
