It is proposed an operational calculus method for obtaining explicit solutions of a class of local and nonlocal BVPs for the Laplace equation. It is based on direct two-dimensional operational calculi built on two non-classical convolutions for the operators ∂xx and ∂yy. The corresponding operational calculi use multiplier fractions instead of convolution fractions. An extension of the Duhamel ...

Electrophoresis is a meticulous method in para-clinical science but has received less attention. In this study, the protein profile of synovial fluid of carpal joint and blood serum in buffalo was detected. Sampling was performed by arthrocentesis of 80 left and right forelimbs and obtaining blood serums of 40 Bubalus bubalis in Ahvaz industrial slaughterhouse. Samples were str...

This paper studies a new classical natural deduction system, presented as a typed calculus named λμlet. It is designed to be isomorphic to Curien-Herbelin’s λμμ̃-calculus, both at the level of proofs and reduction, and the isomorphism is based on the correct correspondence between cut (resp. left-introduction) in sequent calculus, and substitution (resp. elimination) in natural deduction. It is ...

The last fteen years have seen an explosion in work on explicit substitution, most of which is done in the style of the-calculus. In KR95a], we extended the-calculus with explicit substitutions by turning de Bruijn's meta-operators into object-operators ooering a style of explicit substitution that diiers from that of. The resulting calculus , s, remains as close as possible to the-calculus fro...

Peak aortic blood acceleration is recognized to be a sensitive index of global left ventricular performance. In the present study peak acceleration was assessed noninvasively in patients with a continuous-wave Doppler velocity meter. Peak aortic blood velocity and peak blood acceleration were measured by placing the ultrasonic transducer at the suprasternal notch. Measurements were obtained in ...

The general fractional integrals and derivatives considered so far in the Fractional Calculus literature have been defined for functions on real positive semi-axis. main contribution of this paper is introducing a finite interval. As case Riemann–Liouville interval, we define both left- right-sided operators investigate their interconnections. results presented are 1st 2nd fundamental theorems ...

We show that the quotient of a Hom-finite triangulated category C by the kernel of the functor HomC(T,−), where T is a rigid object, is preabelian. We further show that the class of regular morphisms in the quotient admits a calculus of left and right fractions. It follows that the Gabriel–Zisman localization of the quotient at the class of regular morphisms is abelian. We show that it is equiv...
