in this paper, we introduce $p$-semilinear transformations for linear algebras over a field ${bf f}$ of positive characteristic $p$, discuss initially the elementary properties of $p$-semilinear transformations, make use of it to give some characterizations of linear algebras over a field ${bf f}$ of positive characteristic $p$. moreover, we find a one-to-one correspondence between $p$-semiline...

Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. Additionally, in shaly sand formations this assumption may not be true as the ion...

We generally investigate the scalar field model with the lagrangian L = F (X) − V (φ), which we call it General Non-Linear Scalar Field Model. We find that it is the square po-tential(with a negative minimum) that drives the usual linear field solution(φ = φ 0 t) while in K-essence model(with the lagrangian L = −V (φ)F (X)) the potential should be taken as a inverse square form, and their cosmo...

A review of the construction of a Weyl-invariant spinning-membrane action that is polynomial in the fields, without a cosmological constant term, comprised of quadratic and quartic-derivative terms, and where supersymmetry is linearly realized, is presented. The action is invariant under a modified supersymmetry transformation law which is derived from a new Q+K + S sum-rule based on the 3D-sup...

introduction: studies on behavioral patterns and personality traits play a critical role in the prediction of healthy or unhealthy behaviors and identification of high-risk individuals for cardiovascular diseases (cvds) in order to implement preventive strategies. this study aimed to compare personality types in individuals with and without cvd based on the enneagram of personality. materials a...

study of the potential fields at different altitudes, constituting a multiscale field is a class of interpretative methods which are used to approximate depth and geometry of sources. interpretation of potential fields by this class of methods is mainly based on the recognition that the gravity or magnetic fields, generated by ideal sources (point mass, line of mass, sheet and contact) are homo...
