there is a close connection between saltwater intrusion into aquifers and groundwater extraction. freshwater extraction in coastal aquifers is one of the most important reasons for the saltwater intrusion into these aquifers. condition of extraction system such as well depth, discharge rate, saltwater concentration and etc. could affect this process widely. thus, investigating different extract...

In this work, polynomials and the finite q-exponential operator are constructed. The is used to combine an proof of generating function with its extension, Mehler's formula extension Roger's for . Rogers Al-Salam-Carlitz deduced by giving special values

Abstract Very recently, the LHCb Collaboration observed distinct structures with $$cc{\bar{c}}{\bar{c}}$$ c ¯ in $$J/\Psi $$ J / Ψ -pair mass spectrum. In this work, we construct four scalar ( $...

In this paper, we study approximate duals of $g$-frames and fusion frames in Hilbert $C^ast-$modules. We get some relations between approximate duals of $g$-frames and biorthogonal Bessel sequences, and using these relations, some results for approximate duals of modular Riesz bases and fusion frames are obtained. Moreover, we generalize the concept of $Q-$approximate duality of $g$-frames and ...

We consider cyclic codes $\mathcal{C}_\mathcal{L}$ associated to quadratic trace forms in $m$ variables $Q_R(x) = \operatorname{Tr}_{q^m/q}(xR(x))$ determined by a family $\mathcal{L}$ of $q$-linearized polynomials $R$ over $\mathbb{F}_{q^m}$, and three related $\mathcal{C}_{\mathcal{L},0}$, $\mathcal{C}_{\mathcal{L},1}$ $\mathcal{C}_{\mathcal{L},2}$. describe the spectra for all these when is ...

background: q fever is an important widespread reemerging zoonosis. the presence of coxiella burnetii in 100 tick-infested dogs was assessed in this study. methods: the blood samples from 100 referred dogs were acquired and evaluated by nested-pcr. results: c. burnetii was detected in 11 out of 100 (11%) blood samples. most of the positive dogs were kept outdoor and fed on raw diet. based on ou...
