Abstract It is well-known that the number of particles produced in cosmology, commonly defined in the literature from the Fock space of the instantaneous hamiltonian of the canonically normalized fields, is ambiguous.On the other hand, the energy computed from the energy-momentum tensor should be physical.We compare the corresponding Fock spaces an
The solar energy is a source of energy that is abundant in Malaysia and can be easily harvested.However, because of the rotation of the Earth about its axis, it is impossible to harvest the solar energy to the maximum capacity if the solar pabst blue ribbon chandelier thermal collector is placed fix to a certain angle.In this research, a solar ther
The dependences of the coefficient of use of the working time of the change 14b-ca0013dx of the proposed multifunctional unit for harrowing winter crops with simultaneous additional fertilizing with solid mineral fertilizers are theoretically justified.In the conditions of agriculture of Krasnodar Territory, with an increase in the working speed of
Data from animal experiments strongly suggest that ceramide is an important mediator of lipotoxicity in the heart and that accumulation of ceramide contributes to cardiomyocyte apoptosis associated with type 2 diabetes and obesity.However, it remains unknown whether a similar relationship is present also in the human heart.Therefore, we aimed to ex
roue zonda disc In this article, following Gorgi and Yazdanpanah, we define two new concepts of the ideal amenability for a Banach algebra A.We compare these notions with J-weak amenability and ideal amenability, where J is a closed two-sided ideal in A.We also study the hereditary properties of quotient ideal amenability for Banach algebras.Some e
