we study the set of all determinants of adjacency matrices of graphs with a given number of vertices. using brendan mckay's data base of small graphs, determinants of graphs with at most $9$ vertices are computed so that the number of non-isomorphic graphs with given vertices whose determinants are all equal to a number is exhibited in a table. using an idea of m. newman, it is proved that if $...

magnetotelluric (mt) method is an electromagnetic method which provides information about subsurface conductivity structures using earth's natural electromagnetic fields. static shift is one of disorders arising from shallow conductors; therefore static shift must be corrected as one of mt data processing steps. in the absence of sufficient information about the near surface distortions, w...

objective: social determinant of health (sdh) are different from medical care and services. these factors themselves are affected by social policies, and they influence health more than medical care and services do. due to the importance of chronic non-communicable diseases especially diabetes in yazd, and assuming the effect of sdh, the present study was conducted in order to examine the relat...

background and purpose: the age of the onset of obsessive-compulsive disorder (ocd) and its manifestation is now identified at childhood. in the present study, we aimed to epidemiologically assess ocd and its main determinants in school-age children. materials and methods: this cross-sectional study was performed on 600 consecutive schoolage children (7-12 years old) in primary schools at kerma...
