Seismic images and the geologic information they provide contribute significantly to our understanding of the earth’s subsurface. In this thesis, I focus on methods relevant for constructing and interpreting seismic images, including methods for velocity estimation, seismic imaging, and interpretation, which together address key aspects of reflection seismic data processing. Specifically, I pro...

Medical information plays a pivotal role in collecting health information which can be used to determine the main health problems at national and international levels and to change main health policies. Patient management is impossible without having accurate information regarding prevention, treatment and recovery of diseases. Thus, in this issue of International Electronic Journal of Medicine...

the alborz mountains, as a folded and faulting region, is the northern region of crust shortening in iran. dominant mechanism (harvard, 2002) of alborz earthquakes is left-lateral strick-slip paralleled to the range. east alborz is one of the active regions that plays a significant role in the tectonics of its neighbors like south casbin basin. regarding the geological maps of the area, the fau...

introduction: accurate documentation of the cause of death is critical for health care planning. in this study, the most important causes of death registered on death certificates and the most important issues preventing accurate registration and access to death information in the town of rafsanjan were surveyed. methods: this was a descriptive study. all death certificates (totally 1197) issue...

the velocity data of seismic waves in a region has an important role in locating occurred events. information such as velocity ratio of vp/vs and velocity curves for pg, pn, sg, and sn phases directly affect the locating results. it is well known that the vp/vs ratio can be used to predict lithology, and that s-waves are sensitive to microcracks aligned by the present day stress field. also, th...

BACKGROUND AND AIM: Clinical indices that determine the need for orthodontic treatment do not provide information about the impact of malocclusion on the quality of life. The present study was carried out to assess the correlation between the aesthetic component of the Index of Orthodontic Treatment Need (IOTN) and the Child Perception Questionnaire (CPQ11-14) in determining the need for orthod...
