self-concept component and its relationship with family structure and perceived parental rearing practices was examined in a sample of 163 adolescents ( 87 girls and 76 boys, aged 16 years old) selected randomly from high schools in tabriz. the subjects completed tennessee self-concept scale with 84 items and a 77-item inventory measuring parental rearing practices. results revealed no signific...

ABSTRACT I analyse some properties of the luminous transient event SN 2019zrk and conclude that jets were main powering sources pre-explosion outburst (pre-cursor) ejection a massive circumstellar matter (CSM), very energetic explosion itself, post-explosion bump in light curve. The energy source is mainly companion (main sequence, Wolf–Rayet, neutron star, or black hole) star accreted mass lau...

a novel mathematical model has been developed to aid the formulation of emulsion explosives. this mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a ms excel program. the effects of the different content of nh4no3, nano3, h2o, and span-80 and composite fuel oil...

PACS. 61.10.-i – X-ray diffraction and scattering. PACS. 32.80.-t – Photon interactions with atoms. PACS. 36.40.-c – Atomic and molecular clusters. Abstract. – The ingenious idea of single molecule imaging by hard x-ray Free Electron Laser (X-FEL) pulses was recently proposed by Neutze et al. [1]. However, in their numerical modelling of the Coulomb explosion several interactions were neglected...

Abstract In the literature, theory of complex-valued random fields is usually recalled to describe evolution vector data in space, without including temporal dimension. However, as real case, development complex formalism a spatio-temporal context and construction some new classes covariance models are sure interest for scientific community partly due ongoing explosion availability observations...

The response of underwater structures to a near-field explosion is coupled with the dynamics bubble and surrounding water. This multiphase fluid–structure interaction process investigated in paper using two-dimensional model problem that features yielding collapse thin-walled aluminum cylinder. A recently developed computational framework couples finite volume compressible fluid solver element ...
